SYSTEM FOR FORMING A WALL ELEMENT WITH A FREESTANDING SCAFFOLDING SECTION

Description

[0001] The present application claims priority from German patent application No. 10 2021 120 438.0.

[0002] The invention relates to a formwork system for a wall element, comprising at least one formwork panel, at least one connecting component, and at least one scaffold section, wherein the connecting component comprises at least one scaffold interface provided for detachable connection to the scaffold section and at least one formwork interface provided for detachable connection to the formwork panel. The at least one connecting component is connected to the scaffold section via its scaffold interface, and the connecting component is connected to the at least one formwork panel via its formwork interface.The connection between the connecting component and the formwork panel and / or the connection between the connecting component and the scaffold section is designed to be detachable in the assembled state of the system, and the scaffold section is separable from the formwork panel, wherein the scaffold section can be used as a freestanding scaffold section after separation from the formwork panel. The invention further relates to a method for manufacturing a wall element using such a system.

[0003] The invention relates to the field of construction. When constructing or renovating buildings, building components are often formed by pouring concrete. The shape of these cast building components is determined by formwork, which is erected on the construction site before pouring. In particular, ceilings or walls of a building are constructed using formwork. When producing tall walls or wall elements, scaffolding is required to prepare the formwork for the production of the wall element. Scaffolding is needed, firstly, to connect individual formwork panels to form the overall formwork, for example, by attaching formwork locks. Furthermore, two opposing formwork panels must be connected to each other by anchors before the production of a wall element in order to absorb the outward pressure of the poured concrete.For this to work, the formwork panels must be accessible to workers along their entire height, which is usually achieved using scaffolding or a work platform. Furthermore, in most cases, reinforcement must be installed on a pre-positioned temporary formwork or between such temporary formwork and a closing formwork opposite it before the wall element is manufactured. According to current best practices, scaffolding or work platforms intended for installing formwork interlocks are positioned on the formwork in such a way that reinforcement cannot be installed from these scaffolding or work platforms. The points where the reinforcement must be positioned are simply inaccessible from these scaffolding or work platforms used for preparing the formwork panels, as they are located on the opposite side of the panel.In practice, this means that one type of scaffolding is required to operate the formwork, and a second type is needed for positioning and inserting the reinforcement into the formwork. Furthermore, a construction site typically contains a variety of different types of scaffolding and formwork panels, often making it impossible to connect the scaffolding to the formwork panels, especially for the applications described above. Differences in the grid spacing between the scaffolding and formwork systems usually prove problematic. Finally, in many applications, after a wall element has been cast using formwork, further work is required on the element after the formwork has been removed, such as filling anchor holes or applying plaster or paint.To access the wall element along its entire height, scaffolding or a work platform is required again after the actual casting process to perform final work. Therefore, manufacturing a wall element using formwork necessitates a multitude of different scaffolding or work platforms, leading to complex workflows and a need for a variety of different scaffolding components. A system for forming a wall element with the features of the introductory part of claim 1 is disclosed in US5575938A.

[0004] The object of the invention is therefore to propose solutions that can simplify the production of a wall element.

[0005] This problem of the invention is solved according to claim 1 by a system for formwork of a wall element, comprising at least one formwork panel, at least one connecting component, and at least one scaffold section, wherein the scaffold section comprises several vertical uprights and several horizontal beams and extends in three spatial directions, wherein the formwork panel comprises a frame and a formwork skin, wherein the frame has several longitudinal struts and several transverse struts, wherein the longitudinal struts and the transverse struts are arranged substantially perpendicular to each other and the formwork skin is detachably attachable to the frame, wherein in a connected state the formwork skin rests on at least a part of the longitudinal struts and the transverse struts, wherein at least a part of the longitudinal struts and / or transverse struts has an undercut which is oriented in the longitudinal direction of the longitudinal struts and / or transverse struts, wherein the undercut is provided for a positive and force-fit connection with the formwork interface of a connecting component.wherein the connecting component comprises at least one scaffold interface, which is provided for detachable connection to the scaffold section, and at least one formwork interface, which is provided for detachable connection to the formwork panel, wherein the formwork interface comprises at least one clamping element and the clamping element comprises at least two gripping arms, wherein at least one of the gripping arms is movable relative to another gripping arm, wherein the distance between the at least two gripping arms is adjustable, wherein the at least one connecting component is connected to the scaffold section via its scaffold interface, wherein the gripping arms of the clamping element engage at least partially in the undercut on the frame of the formwork panel, thereby providing at least a positive-locking, preferably also a force-locking, connection between the formwork interface and the formwork panel.wherein this connection can be positioned arbitrarily along the undercut, whereby the relative position between the connecting component and the formwork panel is adjustable in a direction parallel to the direction of the undercut, and the connecting component is connected to the at least one formwork panel via its formwork interface, wherein the connection between the connecting component and the formwork panel and / or the connection between the connecting component and the scaffold section is detachable in the erected state of the system, and thus the scaffold section can be separated from the formwork panel, wherein the scaffold section can be used as a freestanding scaffold section after separation from the formwork panel.

[0006] The system according to the invention comprises at least one formwork panel, at least one scaffold section, and at least one connecting component that connects the formwork panel to the scaffold section. The connecting component enables a connection, in particular a structurally sound connection, between the formwork panel and the scaffold section. The connecting component allows the formwork panel and the scaffold section to be easily connected, and the connection and disconnection can be carried out simply and quickly. A system according to the invention typically comprises several formwork panels and can also include more than one scaffold section. For the connection, several connecting components are usually provided, which are arranged at different positions between the formwork panel(s) and the scaffold section.

[0007] The scaffold section of the system according to the invention is formed by a scaffold section according to the prior art and comprises several vertical uprights, which are essentially vertically oriented when erected, and several horizontal ledgers, which are essentially horizontally oriented when erected. These elements of the scaffold section are connected to one another and, when erected, form a scaffold section extending in three spatial directions. The scaffold section can include further elements, such as platforms, ladders, guardrails, and the like. The scaffold section is preferably modular in design, meaning that it can be assembled from standard elements of different sizes and shapes. The scaffold section can, for example, be a so-called system scaffold.

[0008] The system according to the invention further comprises at least one formwork panel with a supporting frame and a formwork skin which is detachably connected to the frame. The frame is preferably constructed in a grid pattern, with several longitudinal struts, which are essentially vertically oriented in the assembled state, and several transverse struts, which are essentially horizontally oriented in the assembled state, forming this frame. The longitudinal struts and the transverse struts are oriented at right angles to each other. The formwork skin is attached to the frame and rests on at least a portion of the longitudinal and transverse struts. This contact allows forces acting on the formwork skin from the concrete material during the production of a wall element to be transferred into the supporting frame of the formwork panel. At least a portion of the longitudinal struts and / or the transverse struts have an undercut.An undercut is an area that is recessed relative to adjacent areas. If a mating element is connected to the formwork panel frame in such a way that it partially engages the undercut, a positive fit is created, connecting the mating element to the frame. The undercut is designed to create a positive and force-fit connection with a formwork interface of a connecting component, as will be described later. The undercut extends along the longitudinal direction of the longitudinal and / or transverse braces. For example, the undercut can be formed by a groove that is recessed relative to the rest of the surface of the longitudinal and / or transverse braces and extends along these braces.This longitudinal extension of the undercut allows a connecting component to be attached to the formwork panel frame at any position. This flexibility in positioning the connecting component makes it very easy to join formwork panels and scaffold sections with different grid patterns. The longitudinal undercut allows for a connection at virtually any position, rendering the grid pattern used between the formwork panel or the formwork system irrelevant for the connection to the connecting component. Preferred embodiments of the undercut are described later.

[0009] The system according to the invention further comprises at least one connecting component with a scaffold interface and a formwork interface. The formwork interface is designed for connection to the formwork panel, in particular to the frame of the formwork panel. For this purpose, the formwork interface comprises at least one clamping element, which in turn comprises at least two gripping arms. These gripping arms are movable relative to each other. The distance between one gripping arm and the other gripping arm is variable or adjustable. The gripping arms of the clamping element are designed to engage, at least partially, in the undercut in the frame of the formwork panel and thus create a positive-locking connection between the connecting component and the formwork panel. In addition to the gripping arms, the clamping element may have further elements, for example, a mechanism for actuating and locking the gripping arms.The connection between the connecting component and the frame of the formwork panel is established by first adjusting the two gripping arms so that they can partially grip a cross member or a longitudinal member of the frame. In this position, the gripping arms are partially slid over the longitudinal member or the cross member until a portion of the gripping arms is positioned adjacent to one or more undercuts on the cross member or the longitudinal member. Subsequently, the distance between the two gripping arms is reduced, with them engaging at least partially in the undercut on the frame. This creates the previously described positive locking connection between the connecting component and the frame of the formwork panel. Preferably, this connection simultaneously creates a force-fit connection, in particular a clamping connection, between the gripping arms and the frame.Such a force-fit connection ensures that there is no play between the connecting component and the formwork panel, thus creating a stable connection capable of withstanding both static and dynamic loads. A particular advantage of this connection is that it can be created at various positions along the longitudinal or transverse brace. This allows the connecting component to be positioned variably relative to the formwork panel frame. The undercut, advantageously, extends over the entire free length of the transverse and longitudinal braces. This enables a connection to be made with the connecting component at virtually any point on the formwork panel frame. Only at the intersections of the longitudinal and transverse braces is such a connection not possible, or only possible with the use of an additional component.The connection between the connecting component and the formwork panel via the clamping element is designed to allow for easy separation, even when the formwork panel and scaffold section are assembled and being used to manufacture a wall element. In the system according to the invention, the connecting component is thus detachable from the formwork panel and / or the connecting component from the scaffold section in the assembled state. This has the advantage that the scaffold section can be separated from the formwork panel in the assembled state during the production of a wall element. Such separability offers advantages in the production of the wall element. For example, one and the same scaffold section can be used for different tasks in the production of the wall element.The scaffold section of a system according to the invention is designed such that, after separation from the formwork panel (preferably also involving the removal of the connecting component), it can be used as a freestanding scaffold section. This means that the scaffold section itself is load-bearing and stable on the ground and can be used by workers as a scaffold section. The connecting component allows the scaffold section to be connected to the formwork panel, for example, to transport or position both components while connected. After separation of the scaffold section and the formwork panel, however, the scaffold section can be used like a conventional scaffold section. Furthermore, it is possible for a system according to the invention to reconnect the two components after a previous separation of the formwork panel and the scaffold section.This is achieved by simply connecting at least one connecting component to both the formwork panel and the scaffolding section.

[0010] The system according to the invention enables the connection of different types or systems of formwork panels and scaffold sections. In particular, the continuously adjustable connection between the formwork interface of the connecting component and the frame of the formwork skin allows for a simple and flexible connection. Preferably, several connecting components, attached at different positions, are provided for connecting a formwork panel to a scaffold section. The scaffold interface of the connecting component is preferably designed to be compatible with a connecting interface used within the scaffold section. Thus, the connecting component can be easily combined with different types of scaffold sections by varying or adapting the scaffold interface.The connecting component has a simple design, enabling the easy and cost-effective provision of a system according to the invention that utilizes an existing scaffold section. This allows existing equipment to be advantageously retrofitted into a system according to the invention. The easy separability of the formwork panel and scaffold section, facilitated by the connecting component with its formwork interface and scaffold interface, offers several advantages in the production of a wall element. The scaffold section can be used for multiple tasks, such as attaching reinforcement to or within the formwork, safely pouring the concrete material into the formwork, and, after removing the formwork panel, for finishing work on the already cast wall element.Thus, the system according to the invention saves effort and working time in the production of a wall element, which is achieved through the multiple use of a single scaffold section. The system according to the invention is therefore particularly suitable for the production of wall elements. Furthermore, the system according to the invention can, of course, also be used for the production of other building elements, such as pillars or columns.

[0011] In one embodiment of the system, the clamping element is designed to be at least partially form-complementary to an element of the formwork panel. Form-complementary here means that a region of the clamping element, in particular the tip area of ​​the gripping arms, has a negative shape corresponding to the undercut on the frame of the formwork panel. This ensures a secure positive fit between the formwork interface and the formwork panel.

[0012] Furthermore, it is provided that the scaffold interface is designed to be at least partially form-complementary to an interface on the scaffold section. Form-complementary here means that at least a portion of the scaffold interface has a negative form corresponding to a portion of an interface on the scaffold section. The scaffold section has interfaces for connecting its components, for example, vertical standards and horizontal ledgers. Preferably, a portion of the scaffold interface of the connecting component is designed to be similar or identical in shape and size to an interface that is also used in the scaffold section. For example, connecting discs with recesses into which interface elements of a horizontal ledger can be positively inserted can be arranged on a vertical standard of the scaffold section.In this case, the scaffold interface of the connecting component can be designed to correspond to the interface on the horizontal ledger. This allows the scaffold interface to be connected to a vertical upright in the same way as a horizontal ledger of the scaffold section. This design allows the connecting component to be easily attached to various positions on the scaffold section.

[0013] According to the invention, a support element is provided which is connected to the formwork interface and the scaffold interface, in particular wherein the support element is rod-shaped, wherein the formwork interface and the scaffold interface are arranged at a distance from each other on the support element, and the support element connects the formwork interface and the scaffold interface to each other. The support element can have various shapes. Preferably, the support element is rod-shaped and can, for example, be formed by a tube or a tube section. The distance between the formwork interface and the scaffold interface on the support element allows the distance between the formwork panel and the scaffold section in the erected state of the system to be adjusted.To allow for individual adjustment of the distance between the formwork panel and the scaffold section when the longitudinal axis of the support element is not oriented according to the invention, the support element can also be designed to be adjustable in length, for example, telescopically. The scaffold interface and the formwork interface can be rigidly connected to the support element or adjustable in their position and orientation.

[0014] According to the invention, the support element has a longitudinal axis, and the formwork interface and the scaffold interface are spaced apart from each other along this longitudinal axis, wherein the longitudinal axis is essentially parallel to the surface of the formwork skin and vertically oriented. The support element has a longitudinal axis that runs between the formwork interface and the scaffold interface.

[0015] Advantageously, a compensating element is provided, which is arranged between the support element and the scaffold interface. This compensating element has a linear bearing, allowing the scaffold interface and the support element to be displaced, at least partially, in a direction parallel to the longitudinal axis of the support element relative to the support element. In this embodiment, a compensating element is provided that enables displacement between the scaffold interface and the support element, and thus also displacement between the scaffold interface and the formwork interface. For this purpose, the compensating element has a linear bearing that facilitates linear movement in a direction parallel to the longitudinal axis of the support element. This displaceability between the scaffold interface and the formwork interface further increases the flexibility of the connection between the formwork panel and the scaffold section.The adjustable design allows for stepless adjustment of the distance between the two interfaces, compensating for tolerance differences or grid variations between the scaffold section and the formwork panel. Furthermore, the leveling element also enables compensation for height differences in the system's substructure. For example, if the substructure beneath the formwork panel is higher than the substructure beneath the scaffold section, this height difference can be continuously compensated for by the leveling element without requiring any modifications to the system.

[0016] Furthermore, it is provided that the distance between the scaffold interface and the formwork interface, particularly in a direction perpendicular to the longitudinal axis of the load-bearing element, is greater than or equal to the thickness of the formwork panel. The distance between the scaffold interface and the formwork interface defines the distance between the formwork panel and the scaffold section. Preferably, the distance between the two interfaces is greater than the thickness of the formwork panel in a direction perpendicular to the surface of the formwork skin. However, this distance can also be smaller. Moreover, the distance can also be significantly larger; for example, the distance between the scaffold interface and the formwork interface, particularly in a direction perpendicular to the longitudinal axis of the load-bearing element, can be greater than three times the thickness of the formwork panel, or greater than five times the thickness of the formwork panel.

[0017] In a further embodiment, two scaffold interfaces and two formwork interfaces are provided, each spaced apart from the others on a common support element. In this embodiment, two scaffold interfaces and two formwork interfaces are arranged on each support element. In this embodiment, the length along the longitudinal direction of the support element is greater than in the previously described embodiments. In this embodiment, the support element is arranged with its longitudinal direction parallel to a vertical upright of the scaffold section in the system. The length of the support element is at least 1 m. Two scaffold interfaces are arranged on the support element, pointing in a first direction, and these are connected to or interconnected with interfaces on the scaffold section.On the opposite side, two formwork interfaces are also arranged, which are connected to, or already connected to, the frame of the formwork panel. Such a connecting component enables a connection at two points between the formwork panel and the scaffolding section. This makes the connecting component more stable and load-bearing. Furthermore, the number of components required to assemble a system is reduced by such a connecting component, thereby simplifying logistics on the construction site and reducing the system's assembly time.

[0018] Cleverly, the clamping element of the two formwork interfaces, which are arranged on a common support element, has a release mechanism that can be actuated by a simple linear or rotary movement. Actuating the release mechanism releases the positive locking connection between the formwork interface and the formwork panel. In this embodiment, the clamping element has a release mechanism that can be operated quickly and easily by hand. This allows the formwork interface of the connecting component to be separated from the formwork panel quickly and easily. This is advantageous when, during the production of a wall element in the disassembled state of the system, the formwork panel needs to be separated from the scaffolding section. The release mechanism makes such separation quick and easy.The unlocking mechanism can be actuated by a simple movement, which can be linear, rotary, or a simple combination of both. For example, the unlocking mechanism can have a rod-shaped lever that is actuated in a linear or rotary motion, thereby releasing the positive locking connection between the formwork interface and the formwork panel. To prevent accidental actuation of the unlocking mechanism, a safety mechanism can be provided which must first be deactivated before the unlocking mechanism can be actuated. Such a unlocking mechanism is preferably used in a connecting component that has two or more formwork interfaces. Such a connecting component is described in the preceding embodiment.It is possible to provide a common release mechanism for multiple formwork interfaces, or for each formwork interface to have its own release mechanism, with the release mechanisms being coupled together. In this way, several formwork interfaces can be simultaneously separated from the formwork panel with a single actuation action. This further reduces the time required to separate the formwork panel and the scaffolding section. Naturally, it is also possible to provide a release mechanism for embodiments of a connecting component that only has one formwork interface.

[0019] In a further embodiment, the direction of movement of at least one of the gripping arms of the clamping element is oriented essentially parallel to the connection direction of the scaffold interface and / or essentially parallel to the surface of the formwork panel. The distance between the two gripping arms of the clamping element is adjustable, with at least one of the gripping arms being movable. In one embodiment, at least one of these gripping arms is movable in a direction that, in the disassembled state of the system, runs essentially parallel to the surface of the formwork panel. In this way, the movement of the gripping arm allows for at least partial gripping of a longitudinal strut or a transverse strut of the formwork panel frame. The direction of movement of the gripping arm is understood to be the direction along which the distance between the two gripping arms is adjustable.The clamping element can also be designed such that both gripping arms are movable. Preferably, the direction of movement of the gripping arm is parallel to a connection direction of the scaffold interface. This connection direction is the direction in which the scaffold interface is moved to establish or release a connection with the scaffold section. The connection direction can be oriented parallel to a vertical upright of the scaffold section, i.e., essentially vertical in the assembled state of the system. In this case, the direction of movement of the gripping arm is also essentially vertical, thus enabling the clamping element to grip around a cross member of the formwork panel.

[0020] In an alternative embodiment, the direction of movement of at least one of the gripping arms of the clamping element is oriented essentially perpendicular to the connection direction of the scaffold interface and / or perpendicular to the surface of the formwork panel. In this embodiment, the direction of movement of one gripping arm is oriented perpendicular to the direction of movement in the previously described embodiment. The direction of movement of at least one of the gripping arms is perpendicular to the surface of the formwork panel. This allows the clamping element to engage an edge region of the formwork panel frame. This enables the connecting component to be positioned at the edge of the formwork panel, thus allowing, for example, the arrangement of a second formwork panel between the formwork panel and the scaffold section. In the assembled state of the system, the direction of movement is preferably horizontal.Thus, the direction of movement is essentially oriented perpendicular to a connection direction of the scaffold interface, which preferably runs in a vertical direction.

[0021] Cleverly, the length of the support element is designed to be adjustable. In this embodiment, the distance between the scaffold section and the formwork panel can be varied by adjusting the support element, even if the longitudinal axis of the support element is not oriented according to the invention. This is particularly advantageous when objects of different thicknesses, such as wall elements to be manufactured, are to be arranged between the scaffold section and the formwork panel. For this purpose, the support element can be telescopically designed. Furthermore, the support element can have at least one locking device with which a set length of the support element can be stably fixed.

[0022] In an advantageous embodiment, the undercut on the frame of the formwork panel is designed as a groove oriented longitudinally along the longitudinal and / or transverse struts, with the groove having a U-shaped, rectangular, or curved cross-section. The undercut can be designed as a groove integrated into the longitudinal and / or transverse struts and extending, at least partially, along these struts. Preferably, the longitudinal and transverse struts have a rectangular cross-section, with the formwork skin resting on a side face of this rectangular cross-section. The undercut is preferably arranged on a side face adjacent to the side face on which the formwork skin rests. Two undercuts can also be arranged on a transverse or longitudinal strut, preferably on two opposing side faces of the struts.In cross-section, such an undercut, designed as a groove, can have a U-shaped, rectangular, polygonal, or semicircular form. Generally, a wide variety of shapes are suitable for the cross-section of the groove, as long as these cross-sections create an undercut relative to the adjacent areas on the transverse or longitudinal member.

[0023] In a further embodiment, at least two connecting components are provided, each having at least two formwork interfaces. The formwork panel has several cross members with an undercut arranged at least partially on it, the distance between the at least two formwork interfaces on the connecting component being an integer multiple of the distance between two adjacent cross members of the formwork panel. In this embodiment, the grids of the formwork panel and the connecting component are coordinated to allow for flexible use of the system components. Each connecting component has two formwork interfaces, which are arranged opposite each other on a support element. The distance between the two formwork interfaces on the support element is an integer multiple of the distance between two cross members of the formwork panel.The distance between two adjacent crossbeams of the formwork panel is less than the distance between the two formwork interfaces on the connecting component. This choice of dimensions allows the connecting component to be attached to different crossbeams of the formwork panel at various positions. In the assembled state of the system, the connecting component can thus be positioned at different heights relative to the formwork panel in the vertical direction. Such variability in the connection position between the connecting component and the formwork panel is particularly useful when several formwork panels are combined to formwork for a wall element. In areas of the combined formwork where two formwork panels meet, it may not be possible to install the formwork interface.In this case, the connection with the connecting component can be positioned offset from the points where two formwork panels meet. This allows a connection between a scaffold section and a formwork panel via the connecting component even if the overall size or shape of the formwork and / or the scaffold section is varied.

[0024] Advantageously, the formwork panel and the scaffold section are arranged parallel to each other, with the distance between the formwork panel and the scaffold section determined by the connecting component. Such a parallel arrangement of formwork panel and scaffold section is particularly advantageous when producing a wall element, as the formwork or the wall element is always at a constant distance from the scaffold. Of course, it is also possible to arrange the formwork panel and scaffold section at a different angle to each other, for example, if the wall element to be produced has an irregular or angular shape.

[0025] Furthermore, it is advantageously provided that the clamping element comprises a pin element and a clamping element, wherein the pin element is positively engaged in a recess, in particular a bore, in one of the longitudinal or transverse struts of the formwork panel, and the clamping element is movable relative to the pin element and bears at least partially against one of the longitudinal or transverse struts, wherein a clamping mechanism is provided which generates the relative movement between the pin element and the clamping element, and wherein the clamping mechanism creates a positive and a force-fit connection between the connecting component and the frame of the formwork panel. In this embodiment, the undercut on the frame of the formwork panel is formed by a recess or a groove in a transverse strut or a longitudinal strut.The clamping element incorporates a pin element which, during connection, engages positively in the recess on the frame. The pin element has a negative shape in some areas corresponding to the recess and forms a movable gripping arm of the clamping element. In this embodiment, the second gripping arm is formed by a clamping element which, during connection to the frame, rests against and partially encloses a longitudinal or transverse strut. A clamping mechanism is arranged between the pin element and the clamping element, generating relative movement between the two elements or gripping arms. Actuation of the clamping mechanism reduces the distance between the pin element and the clamping element, thereby establishing a force transmission and a positive connection between the frame interface and the formwork panel frame.

[0026] Cleverly, the scaffold interface, which is spaced apart from the formwork interface on a support element, is designed as a connecting clamp, with the connecting clamp being force-fitted to a vertical upright of the scaffold section. In this embodiment, the scaffold interface is designed as a connecting clamp that is force-fit and positively locked to a vertical upright of the scaffold section. This connection point can be positioned almost arbitrarily on the vertical upright. In this embodiment, the scaffold interface is therefore not identical to an interface used to connect components within the scaffold section. The connecting clamp encircles a vertical upright and is clamped at the desired connection position, for example, by means of a screw connection.A scaffold interface designed as a connecting clamp has the advantage of being particularly flexible with regard to the relative position between the connecting component and the scaffold section. This design therefore also allows for the compensation of tolerances or differences in the ground height beneath the formwork panel and the scaffold section between the connecting component and the scaffold section.

[0027] In an alternative embodiment, the formwork interface is formed by an compensating rail and the scaffold interface by a clamping clamp, wherein the compensating rail is inserted into the undercut in the frame of the formwork panel with a first sub-section forming a gripping arm, wherein the second gripping arm is formed by a locking pin which can be inserted into the first sub-section, and the compensating rail has a second sub-section which is designed as a rail with a constant cross-section, and the clamping clamp has a connection section which is at least partially form-complementary to the compensating rail, and the clamping clamp further has a locking element which can be inserted into the connection section, and in the connected state the connection section and the locking element together completely enclose the compensating rail.wherein the clamping clamp is designed to be displaceable parallel to the longitudinal direction of the compensating rail and the clamping clamp further comprises a connecting clamp which is arranged adjacent to the connection area, the connecting clamp being force-fitted to a vertical post of the scaffold section. In this embodiment, the formwork interface is designed as a compensating rail. A formwork interface designed in this way comprises a first sub-section which is positively engaged in an undercut in the frame and which forms a first gripping arm. In this embodiment, the undercut penetrates a longitudinal strut or a transverse strut in the frame and the first sub-section is inserted into the undercut in such a way that it penetrates the entire longitudinal strut or transverse strut. In this embodiment, a locking pin is provided as the second gripping arm.which can be inserted into the first section. During connection, the first section is guided through the undercut in the frame, and then the locking pin is inserted into the part that protrudes beyond the longitudinal or transverse strut. In this way, the formwork interface is positively connected to the frame of the formwork panel. Adjacent to the first section, the compensating rail has a second section, which is designed as a rail with a constant cross-section. This rail then serves to connect to the scaffold interface.which is designed as a clamp. Providing the second section as a rail with a constant cross-section improved flexibility regarding the relative position between the formwork panel and the scaffold section. Using this rail with a constant cross-section, the relative position between the formwork interface and the scaffold interface within the connecting component can be varied along its length. Thus, this embodiment not only offers variability regarding the attachment of the connecting component to the formwork panel and the scaffold section, but also provides additional variability or adjustability within the connecting component itself. This embodiment is particularly advantageous becauseThis is particularly relevant if the formwork panel has undercuts at only discrete points on its frame. Such formwork panels are often found in the inventory of construction companies and are intended for future use. A connecting component according to this embodiment allows such older formwork panels to be used very flexibly within a system. The adjustability of the scaffold interface relative to the formwork interface is further enhanced by the connection area of ​​the clamping bracket, which in this embodiment forms the scaffold interface. This connection area is at least partially form-complementary to the second section of the compensating rail. This means that the connection area encompasses a section of the compensating rail. For a secure connection between the scaffold interface and the formwork interface, the clamping point also features a locking element.which can be inserted into the connection area and, together with the connection area in the connected state, completely encircles the rail with a constant cross-section. The locking element is designed in such a way that a force-fit connection can also be established between the clamping point and the compensating rail. During the connection process, the connection area is first slid over the second section of the compensating rail. In this state, the connection area can be moved relative to the compensating rail along the length of the rail with a constant cross-section, allowing the position between the formwork interface and the scaffold interface to be adjusted. Subsequently, the locking element is inserted into the connection area.This creates a positive and force-fit connection between the components. In this state, the connecting element is fixed. The connection of the scaffold interface to the scaffold section is achieved, as in the previously described embodiment, via a connecting clamp which, in the connected state, encloses a vertical post of the scaffold section and is force-fitted to it. As previously described, this connecting clamp is advantageous here because it can be positioned almost steplessly relative to a vertical post of the scaffold section. The described embodiment thus exhibits a very high degree of adaptability with regard to the shape and positioning of the connecting element between the formwork panel and the scaffold section.

[0028] The object of the invention is further achieved according to claim 6 by a method for manufacturing a wall element comprising the steps A) Erecting a temporary formwork comprising at least one formwork panel, B) Attaching reinforcement to the erected temporary formwork, C) Erecting a closing formwork, wherein the temporary formwork and the closing formwork define the area in which the wall element is provided, and wherein the reinforcement is arranged between the temporary formwork and the closing formwork, and wherein the closing formwork is formed by a system according to one of the previously described embodiments, the formwork panel of which is oriented towards the reinforcement and the scaffold section of the system is arranged on the side of the formwork panel opposite the temporary formwork, D) Preparing the formwork for the injection of a liquid material between the temporary formwork and the closing formwork, wherein, in particular, anchors are inserted which connect the temporary formwork and the closing formwork to each other, E) Filling the formwork with a liquid material, F) Curing of the material.whereupon this, together with the reinforcement, forms the wall element, G) Separation of the formwork panel from the scaffold section, wherein the scaffold interface of the connecting component is detached from the scaffold section or the formwork interface of the connecting component is detached from the formwork panel, H) Removal of the formwork panel, wherein the scaffold section remains in an unchanged position, I) Machining of the cast wall element from the scaffold section.

[0029] The method according to the invention can be used to manufacture a wall element of a building. However, this method is also suitable for manufacturing other building elements, such as columns or pillars. Preferably, the method is carried out in the specified sequence of process steps A) to I). However, it is also possible to modify the sequence of the process steps.

[0030] In a first process step, a temporary formwork system is erected, comprising at least one formwork panel. Temporary formwork is understood to be the formwork system that is erected as the first part of the formwork before the construction of a wall element. The temporary formwork is typically erected on the substrate on which the wall element is to be constructed. To secure the temporary formwork against tipping over, it preferably has a support, which is positioned on the side of the temporary formwork facing away from the wall element to be erected. Preferably, the temporary formwork comprises several interconnected formwork panels. Process step A) is completed as soon as the entire temporary formwork system is erected and thus positioned.

[0031] In a second process step B), reinforcement is arranged and attached to or in front of the formwork. The reinforcement serves to strengthen the wall element to be erected and can, for example, consist of steel mesh. For tall wall elements, scaffolding or a work platform is required to attach the reinforcement to the formwork. The reinforcement is preferably positioned and attached to the formwork using fasteners such as wire.

[0032] After the reinforcement has been arranged, a closing formwork is erected opposite the initial formwork as a third process step (C). According to the invention, this closing formwork is formed by a system according to one of the previously described embodiments. The system forming the closing formwork is erected such that the formwork skin of the system's formwork panel faces the reinforcement and the initial formwork. In the dismantled state, the initial formwork and the formwork panel of the closing formwork then define the space in which the wall element is to be created. The reinforcement is also arranged between the initial formwork and the closing formwork. The system, comprising at least one formwork panel, at least one connecting component, and at least one scaffold section, is assembled, with the scaffold section being arranged on the side of the system's formwork panel facing away from the initial formwork.In this way, formwork is created, formed on one side by the positioning formwork and on the other side by the closing formwork formed by the system. The scaffold section is positioned outside the area in which the wall element is to be constructed. At the end of process step C), all components are fixed in place. The scaffold section, which is connected to the formwork panel of the system, can then be accessed by workers and used to carry out work.

[0033] In a fourth process step D), the formwork, consisting of the initial formwork and the closing formwork panel, is prepared for the pouring of liquid concrete. The closing formwork typically also comprises several panels, which must be tightly connected before the wall element is produced. To connect multiple panels, formwork interlocks are installed, linking adjacent panels together. These interlocks are installed from the scaffolding section of the closing formwork. From this scaffolding section, workers can access the entire back of the panels. Furthermore, during formwork preparation, anchors are installed between the panels of the initial formwork and the closing formwork. These anchors ensure the formwork's structural stability during the pouring of the concrete.Several anchors must be positioned at various locations between the formwork and the closing formwork. This installation or insertion of the anchors is also carried out by personnel on the scaffold section. The scaffold section is thus used for various tasks and work during the formwork preparation.

[0034] In a fifth process step E), liquid material, preferably a concrete mix, is poured into the formwork. This pouring of the material can also be carried out from the scaffold section. The scaffold section provides a secure platform from which supply elements for the concrete mix, such as hoses, can be positioned according to the area enclosed by the formwork. Alternatively, the scaffold section can also be used solely for observing and evaluating the filling of the formwork.

[0035] In a sixth process step (F), the poured material is given time to harden and form a load-bearing wall element. During this process step, the framework section can be used to observe and, if necessary, influence the hardening process, for example, by adding water.

[0036] In a seventh process step (G), the formwork panel is separated from the scaffold section in its disassembled state during the closing formwork formed by the system. This can be achieved either by separating the scaffold interface of the connecting component from the scaffold section, leaving the connecting component attached to the formwork panel, or alternatively, by detaching the formwork interface of the connecting component from the formwork panel, leaving the connecting component attached to the formwork panel. Due to the design of the connecting component, this separation can be carried out quickly and easily from the scaffold section. In particular, no special tools are required to separate the formwork panel and the scaffold section, and all or at least most of the necessary steps can be performed manually.An advantage of this method is that the scaffold section remains stable and load-bearing on its own even during and after separation from the formwork panel, and can be continuously accessed and used for work by personnel.

[0037] In an eighth process step (H), the formwork panel of the closing formwork is removed, while the scaffold section remains in its original position. Preferably, the formwork panel of the closing formwork is removed vertically upwards by a crane. It is possible that, prior to removal, the formwork panel must be separated from the produced and cured wall element through further work steps. After removal of the formwork panel, the scaffold section is positioned relative to the newly produced wall element. The distance between the scaffold section and the wall element is approximately equal to the thickness of the previously removed formwork panel. This small distance now allows access to the wall element from the scaffold section. Additionally, the temporary formwork can also be removed in this process step, as the wall element is cured and self-supporting.

[0038] In a final, ninth process step (I), the cast wall element is further processed from the scaffold section that remains in position. This further processing allows, for example, filling holes in the wall element caused by the previously installed anchors. Furthermore, unevenness in the wall element can be removed. Finally, it is also possible to carry out plastering or painting work on the wall element from the scaffold section. This allows for very efficient work, as the subsequent work steps can be performed directly from the same scaffold section immediately after the formwork is removed.

[0039] The method according to the invention has the advantage that the scaffold section, which is part of the closing formwork, is used multiple times during the production of the wall element. First, in process step C), the scaffold section is erected together with the formwork panel that forms the closing formwork. In particular, if the system is assembled or mounted before the closing formwork is erected, the scaffold section can be erected or positioned very quickly. Preferably, the assembled system is simply positioned using a crane. In this way, the closing formwork, with the scaffold section already attached to it, is erected and positioned within a very short time. The formwork can then be prepared from the scaffold section. Without any further modifications to the scaffold section or the formwork, the concrete material can then be poured into the formwork from the scaffold section.Finally, after stripping the formwork, the system's formwork panel can be removed, leaving the same scaffold section in the same position for post-processing of the produced wall element. Compared to conventional methods, only a single scaffold section is required for tasks that would otherwise require at least two different scaffold sections. This saves time and effort during the production of the wall element. Furthermore, logistics on the construction site are simplified, as only a single scaffold section needs to be transported, assembled, disassembled, and removed, whereas otherwise at least two different scaffold sections would need to be kept on hand and processed. The inventive method thus significantly increases efficiency on the construction site and considerably simplifies the production of a wall element.In the method according to the invention, at least one system according to one of the previously described embodiments is used to produce a wall element. Using one embodiment of a system to produce a wall element provides the same advantages previously described for the method.

[0040] In one embodiment of the method, the formwork panel, the scaffold section, and at least one connecting component of the system are assembled before process step C). In this embodiment, the complete system, or at least a part of the system, is assembled before the system is erected as a closing formwork. This assembly can be carried out, for example, while the system is lying on the ground or a surface. This has the advantage that there are no risks of falls during assembly, which are otherwise present when erecting a scaffold section. Assembling the system on the ground thus significantly improves the occupational safety of the workers. Furthermore, the system can be pre-assembled in this way away from the location where the wall element is to be constructed.The fully assembled system can then be transported very quickly, for example with the help of a crane, to the location where the wall element is to be manufactured. This approach also improves logistics at the construction site and reduces the number of people in the danger zone near the installation location of the wall element.

[0041] In a further embodiment, the connecting component is attached to the side of the formwork panel facing away from the formwork skin, thus connecting the frame section to the frame on the side of the formwork panel facing away from the formwork skin. In this embodiment, the connecting component is attached to the formwork panel, and in particular to its frame, on the side facing away from the formwork skin. Preferably, several connecting components are arranged between a formwork panel and a frame section. This allows the frame of the formwork panel to be used for attaching one or more connecting components. The frame has a plurality of transverse and longitudinal struts, so that one or more connecting components can be attached to the formwork panel at various points.This also makes it possible to create a stable and load-bearing connection at several points between the formwork panel and the scaffold section using connecting components.

[0042] The object of the invention is further achieved according to claim 8 by an alternative method for manufacturing a wall element comprising the steps I) Construction of a system according to one of the previously described embodiments, wherein the at least one connecting component is connected to the scaffold section via its scaffold interface and to the formwork panel via its formwork interface, and wherein the system forms a temporary formwork system; II) Attachment of reinforcement to the formwork skin of the formwork panel of the system, wherein the reinforcement is attached from the scaffold section; III) Erection of a closing formwork, wherein the closing formwork is placed between the formwork panel and the scaffold section, and wherein the closing formwork and the formwork skin of the formwork panel define the space in which the wall element is provided, and wherein the reinforcement is arranged between the closing formwork and the formwork panel; IV) Preparation of the formwork for the pouring of a liquid material between the temporary formwork and the closing formwork, wherein, in particular, anchors are inserted.which connect the formwork and the closing formwork, V) Filling the formwork with a liquid material, VI) Hardening of the material, whereby it forms the wall element together with the reinforcement, VII) Separation of the formwork panel from the scaffold section, whereby the scaffold interface of the connecting component is detached from the scaffold section or the formwork interface of the connecting component is detached from the formwork panel, and removal of the formwork panel, VIII) Removal of the closing formwork, whereby the scaffold section remains in an unchanged position, IX) Finishing of the cast wall element from the scaffold section.

[0043] This second method according to the invention is linked by the common inventive concept of first connecting a scaffold section to a formwork panel and subsequently separating these two components again, whereby the scaffold section is used multiple times. The two methods according to the invention represent alternative solutions to the same problem and are complementary to each other.

[0044] The second method according to the invention also serves to produce a wall element using a system according to one of the embodiments described above. Preferably, the second method is also carried out in the specified sequence of process steps. However, if necessary, the process steps can also be partially reversed.

[0045] In a first process step (I), such a system is assembled, with the connecting component being arranged between a formwork panel, which serves as the positioning formwork, and a scaffold section supported by the formwork panel. In contrast to the previously described method according to the invention, the distance between the formwork panel and the scaffold section of the system is significantly greater in the second method. The distance between the formwork panel, which here forms the positioning formwork, and the scaffold section is chosen such that the wall element and a closing formwork to be installed yet to fit within this space. After the system is assembled, it stands stably and load-bearing on the ground, with the scaffold section holding the formwork panel in position via the connection with the connecting component, so that no further support mechanisms for the positioning formwork are required. In this way, such additional support mechanisms are eliminated, which reduces the effort.

[0046] In a second process step (II), reinforcement is attached to the formwork skin or panel of the system, which serves as the formwork support. The reinforcement is attached to the formwork panel by workers located on the scaffolding section of the system, from where they can easily reach the formwork panel to its full height. This eliminates the need for additional scaffolding or work platforms, which are typically required for attaching the reinforcement to the formwork panel according to current best practices.

[0047] In a third process step (III), a closing formwork is erected, the closing formwork being formed in particular by an additional formwork panel which is inserted into the already erected system between the formwork panel serving as the positioning formwork and the scaffold section. After the closing formwork is erected, the positioning formwork and the closing formwork define the area in which the wall element is to be produced and in which the reinforcement was already installed in the previous step. The formwork panel forming the closing formwork is preferably inserted vertically from top to bottom between the scaffold section and the positioning formwork. For this purpose, a crane can be used, for example, to lower the closing formwork at this point.

[0048] In a fourth process step (IV), the formwork is prepared for the pouring of liquid concrete between the initial formwork and the final formwork. This preparation involves, in particular, installing locks between adjacent formwork panels and inserting anchors that hold the initial and final formwork together and absorb the forces exerted on the formwork by the subsequently poured concrete. This formwork preparation can be carried out from the scaffold section, which is now located on the side of the final formwork facing away from the initial formwork. Thus, the final formwork is very easily accessible from the scaffold section. The advantage here is that the scaffold section is already in position, and the formwork preparation can be carried out directly from there after the final formwork has been erected.

[0049] In a fifth process step (V), the formwork is filled with a liquid concrete material, which encases the reinforcement arranged within it. This forms the wall element. The liquid material can be poured into the formwork from a section of scaffolding, which remains in the same position.

[0050] In a sixth process step (VI), the concrete material is cured, creating a load-bearing wall element. The curing process can be checked from the scaffolding section.

[0051] In a seventh process step (VII), the system consisting of the formwork panel forming the positioning formwork, the scaffold section, and the connecting component is dismantled. For this purpose, the connecting component is separated from at least the formwork panel or the scaffold section. Alternatively, the connecting component can be separated from both the formwork panel and the scaffold section. Once dismantled, the formwork panel forming the positioning formwork is removed. This removal can be carried out, for example, by a crane. The separation of the connecting component from the formwork panel or the scaffold section can also be performed from the scaffold section.

[0052] In an eighth process step (VIII), the formwork panel located between the manufactured wall element and the scaffold section, which formed the closing formwork, is removed. This removal is again preferably carried out vertically, for example by a crane. During and after the removal of the closing formwork, the scaffold section remains in its original position.

[0053] In a ninth process step (IX), the produced wall element undergoes finishing work. This finishing work can include, for example, filling and smoothing the anchor holes in the wall element. Other finishing work can also be carried out, such as plastering or painting the wall element. This finishing work is again performed from the scaffolding section, which remains in the same position throughout the entire process. This allows finishing work to begin immediately after the formwork is removed, eliminating the need for the time-consuming erection of scaffolding after the wall element has been produced. Furthermore, it is possible to attach additional formwork from the scaffolding section, for example, to create a ceiling section adjacent to the completed wall element.

[0054] The second method according to the invention also has the advantage that a scaffold section, which is erected here already in the first process step I), is used multiple times and for different tasks during the production of the wall element. This saves time and effort for the assembly and disassembly of different scaffold systems for different tasks. In addition, the scaffold section is advantageously used, in conjunction with the connecting component, as a support for the formwork to prevent it from tipping over. This eliminates the need for other support mechanisms, such as pivoting supports arranged on the formwork. This further simplifies and accelerates the method for producing the wall element compared to the prior art.

[0055] In one embodiment of the second method, it is provided that in process step I), the formwork panel and the scaffold section are erected at a distance from each other, and the length of at least one connecting component is equal to or greater than the thickness of the wall element to be produced. In this embodiment, the length of the connecting component determines the distance between the formwork panel, which serves as the positioning formwork, and the scaffold section. The length of the connecting component between its formwork interface and scaffold interface is equal to or greater than the thickness of the wall element to be produced. Preferably, the length of the connecting component is greater than the sum of the thickness of the wall element and the thickness of the closing formwork to be used.

[0056] Furthermore, it is provided that in process step I), at least one connecting component is attached to the upward-facing edge of the formwork panel via the formwork interface. In this embodiment, the connecting component is attached to the formwork panel by securing the formwork interface to the vertically upward-facing edge of the formwork panel. The connecting component is thus positioned outside the area where the reinforcement is attached and where the wall element is subsequently formed. Therefore, this arrangement eliminates any risk of collision between the connecting component and the wall element being produced. The arrangement of the connecting component at the upper edge of the formwork panel is also particularly effective in securing the formwork panel, which here forms the temporary formwork, against tipping over. The connecting component is preferably connected to the scaffolding section in an upper area via the scaffolding interface.This arrangement also allows the formwork panel, which forms the closing formwork, to be inserted between the scaffold section and the reinforcement after the reinforcement has been installed, without causing a collision with the connecting component. Alternatively, it is also possible to connect the connecting component, or one or more additional connecting components, to the formwork panel at one or more lateral edges via the formwork interface. The formwork interface can, for example, be designed to enclose the edge area of ​​the formwork panel and clamp it in the closed position.

[0057] It is also possible to carry out process steps VII) and VIII) in reverse order. In this embodiment of the second process, after the wall element has been manufactured, the closing formwork, which is located between the scaffold section and the wall element, is removed first. During this removal of the closing formwork, the connecting component can remain in its assembled position and connect the scaffold section to the formwork panel that forms the positioning formwork. Only after the closing formwork has been removed is the connecting component then dismantled and the formwork panel that forms the positioning formwork removed. Even with this alternative sequence of process steps, the scaffold section always remains in its original position to allow for subsequent finishing of the wall element.

[0058] Cleverly, the scaffold section is anchored in the ground during process step I). This anchoring further improves the system's stability during and after the wall element's construction. The scaffold section, which also serves as support for the formwork, can thus transfer forces into the subsoil or ground via the anchoring. Additionally or alternatively, the formwork panel, which forms the formwork and is part of the system, can also be anchored in the ground.

[0059] Cleverly, the system is designed so that in process step I), the scaffold section is either erected on the ground as in the application scenario or laid on the ground for assembly. Several options exist for assembling the system and process step I). Firstly, the system can be erected from the bottom up, starting from the ground or subsoil, which corresponds to the assembly sequence typically used for a scaffold section. Alternatively, the scaffold section can also be erected lying flat on the ground at a different location, away from where the wall element is to be constructed. This has the advantage that there is no risk of falls for workers during the erection of the scaffold section, thus requiring fewer safety precautions.Furthermore, the scaffolding can be erected at a less busy location on the construction site than the actual building site. This streamlines logistics and facilitates work on the site. The scaffolding section, assembled horizontally, can then be positioned, for example by crane, at the location where the wall element is to be constructed. The connection between the formwork panel, which forms the temporary formwork, and the scaffolding section via the connecting component is preferably made at the location where the wall element is to be constructed. Alternatively, it is also possible to assemble the system, consisting of the formwork panel, connecting component, and scaffolding section, at a different location and then position it fully assembled at the site where the wall element is to be constructed.

[0062] In the figures, identical elements are labelled with the same reference symbols. Generally, the described properties of an element in one figure also apply to the other figures. Directional terms such as "up" or "down" refer to the described figure and should be applied analogously to other figures.

[0063] Fig. 1 Figure 1 shows a perspective view of a first embodiment of a system 100 according to the invention. In this embodiment, the illustrated system 100 according to the invention comprises two formwork panels 2, which are oriented towards the rear left. The two formwork panels 2 are arranged vertically one above the other and are rigidly connected to each other. In the illustrated embodiment, two identical formwork panels 2 are connected to each other to increase the formwork in its vertical extent. A system according to the invention comprises at least one formwork panel 2. The system 100 further comprises a scaffold section 3, which is oriented towards the front right, wherein the formwork panel 2 and the scaffold section 3 are connected to each other by four connecting elements 1. This connection between the formwork panel 2 and the scaffold section 3 is designed to be detachable.It is possible to extend the system 100 by providing several parallel or aligned formwork panels 2 and / or several scaffold sections 3, or by providing a longer or higher scaffold section 3.

[0064] Each formwork panel 2 comprises a frame 21 on which a formwork skin 22 is arranged on the side facing rear left in the illustration. The frame 21 is constructed of steel tubes with a rectangular cross-section. The frame is surrounded by a rectangular rim that runs around the frame 21. Within this rectangular rim, a plurality of transverse braces 212, which are oriented horizontally in the illustration, are provided. Perpendicular to these, two vertically oriented longitudinal braces 211 are arranged in the frame 21 in the illustrated embodiment. The transverse braces 212 and the longitudinal braces 211 intersect and are connected to each other at each intersection point. This creates a stable, grid-like frame 21 on which the formwork skin 22 rests, at least partially. Preferably, the connection between the formwork skin 22 and the frame 21 is designed so that it can be easily separated, thus enabling simple replacement of the formwork skin 22.The cross braces 212 and the longitudinal braces 211 are oriented essentially perpendicular to each other. Of course, different braces can also be arranged at a different angle to each other. In the illustrated embodiment, all cross braces 212 have at least one undercut 213. In the illustrated embodiment, each cross brace 212 has two undercuts in 213, which are arranged on opposite sides of the cross braces 212, namely on the sides that point upwards and downwards in the illustration. Details of a cross brace 212 and the undercuts 213 are given in [reference missing]. Fig. 3 The undercuts 213 extend along the transverse struts 212 in their respective longitudinal directions. In the illustrated embodiment, the undercuts 213 extend along the entire length of the transverse struts 212. It is also possible to arrange at least one identical or similarly designed undercut 213 along the longitudinal struts 211, at least in certain areas.

[0065] Scaffold section 3 extends in three spatial directions, has a three-dimensional structure, and, in the illustrated embodiment, features three platforms arranged parallel and one above the other. These three platforms allow convenient access to the entire rear of the formwork panel 2 for personnel standing on scaffold section 3. Scaffold section 3 comprises several vertical uprights 51, oriented vertically in the illustration, and several horizontal ledgers 52, oriented horizontally in the illustration. The vertical uprights 51 and the horizontal ledgers 52 are connected to each other via interfaces. These interfaces are designed as connecting discs or rosettes, which are fixed to the vertical uprights 51. The horizontal ledgers 52 have connection areas that can be positively engaged with the connecting discs or rosettes.In this way, scaffold section 3 has a modular structure and can therefore have various shapes and sizes, which can be formed by standardized vertical standards 51 and horizontal ledgers 52. Furthermore, the illustrated scaffold section 3 has treads on each of its three platforms, each of which is connected to several horizontal ledgers 52. Scaffold section 3 can also include additional scaffold elements, such as guardrails or ladders.

[0066] In the illustrated system 100, the formwork panel 2 and the scaffold section 3 are connected to each other via a total of four connecting components 1. Each of these connecting components 1 comprises a support element 13, which is designed here as a rod. The support element 13 has a longitudinal axis that extends in the direction in which the support element 13 has its longest dimension. In the illustrated embodiment, the longitudinal axis of the support elements 13 is oriented vertically and runs parallel to the vertical uprights 51 of the scaffold section 3. In the illustrated embodiment, the support element 13 is formed by a metal tube with a square cross-section. Of course, it is also possible to design the support element 13 differently, for example as a tube with a round cross-section or as an aluminum or plastic profile.In the illustrated embodiment, each connecting component 1 has two formwork interfaces 12 and two scaffold interfaces 11. Each formwork interface 12 is for connecting the connecting component 1 to the formwork panel 2, and each scaffold interface 11 is for connecting the connecting component 1 to the scaffold section 3, and is connected to these components in the illustrated state. Details of the formwork interface 12 and the scaffold interface 11 are enlarged in Figure 1. Fig. 2 as shown. In the illustrated embodiment in Fig. 1 The longitudinal axis of the support element 13 of the connecting component 1 is oriented essentially parallel to the surface of the formwork skin 22 and also essentially parallel to the frame 21 of the formwork panel 2. Two formwork interfaces 12 are arranged on the support element 13, pointing towards the formwork panel 2. On the opposite side of the formwork interface 12, two scaffold interfaces 11 are arranged on the support element. Both the formwork interfaces 11 and the scaffold interfaces 12 are spaced apart from each other in a direction parallel to the longitudinal axis of the support element 13. In the illustrated embodiment, each connecting component 1 thus has two mutually opposing connection points between the connecting component 1 and the formwork panel 2, and two mutually opposing connection points between the connecting component 1 and the scaffold section 3. Additionally, the four connecting components 1 are spaced apart from each other.Two connecting components 1 are positioned vertically one above the other with their longitudinal axes aligned. In the horizontal direction shown in the illustration, two connecting components 1 are oriented with the longitudinal axes of their supporting elements 13 parallel to each other. This arrangement results in a total of eight connection points between the formwork panel 2 and the connecting components 1, as well as between the scaffold section 3 and the connecting components 1. In this way, the formwork panel 2 and the scaffold section 3 are stably and securely connected. This stable connection allows, for example, the system 100 to be transported together suspended from a crane. The connection is so stable that it is sufficient to attach a crane hook to either the formwork panel 2 or the scaffold section 3, whereby, during lifting, the connection points between the scaffold section 3 and the formwork panel 2 are sufficiently stable to support the other component.

[0067] The cross braces 212 of the frame 21 are mostly arranged at a constant distance from one another. The distance between two formwork interfaces 12 is significantly greater than the distance between two adjacent cross braces 212. The distance between the two formwork interfaces 12, which are arranged on a common support element 13, corresponds to an integer multiple of the distance between two adjacent cross braces 212. This ensures that the grid of the frame 21 and the connecting component 1 are compatible. This means that the positions of two cross braces 212 and the two formwork interfaces 12 correspond to each other, enabling a positive-locking connection. The connecting component 1 can be attached at different positions relative to the frame 21. The connecting component 1 can therefore be offset within the grid of the cross brace 212 spacing relative to the formwork panel 2.This makes it possible to connect a connecting component 1 to one or more formwork panels 2. In the illustrated embodiment, two formwork panels 2 are arranged vertically one above the other and connected to each other. At this connection point, which in the illustration is located approximately in the middle of the system 100 in the vertical direction, it is often not possible to attach a formwork interface 12. Because the distance between two formwork interfaces 12 on a connecting element 1 is an integer multiple of the distance between two cross braces 212, the connecting component 1 can also be arranged such that one of the two formwork interfaces 12 is attached to a formwork panel 2 and the second of the two formwork interfaces 12 is attached to an adjacent formwork panel 2, with the connecting component 1 simply overlapping the boundary area between the two formwork panels 2.This allows the system 100 to be flexibly mounted in different positions relative to each other, and thus always adaptable to individual applications. In the illustrated embodiment, each connecting component 1 is connected to only one formwork panel 2. However, it would also be possible, for example, to arrange a further, fifth connecting component 1 such that it is connected between the already positioned connecting components 1 with a first formwork interface 12 to the upper formwork panel 2 and with its second formwork interface 12 to the lower formwork panel 2. The position of the connecting component 1 relative to the formwork panel 2 is also flexibly selectable in a direction parallel to the cross braces 212. Details can be found in [reference missing]. Fig. 2 presented and described.

[0068] Fig. 2 shows a perspective detail view of a first embodiment of a system 100 according to the invention. Fig. 2 This is a detailed view of System 100. Fig. 1 to see which area II from Fig. 1 The connecting component 1 includes the support element 13, which is oriented vertically here. Fig. 2 A formwork interface 12 is shown, which is positively and force-fit connected to a cross member 212. The formwork interface 12 includes a clamping element 121 with two gripping arms 1211. The upper gripping arm 1211 is fixedly connected to the support element 13. The lower gripping arm 1211 is movable relative to the upper gripping arm 1211, and the distance between the two gripping arms 1211 is adjustable. The clamping element 1211 also includes a release mechanism 1220, which moves the lower gripping arm 1211 relative to the upper gripping arm 1211. The release mechanism 1220 has a lever pointing forward to the left as its actuating element. Actuating this lever changes the distance between the two gripping arms 1211. The lever can be actuated by a simple linear movement.The clamping element 121 is connected to a cross member 212, with the gripping arms 1211 engaging partially in an undercut 213 on the frame 21. In the illustrated embodiment, an undercut 213 with a rectangular cross-section runs along the upward-facing side of each cross member 212. A sectional view through a cross member 212 is shown in . Fig. 3 As shown, an undercut 213 is also arranged on the downward-facing side of the crossbeams 212, opposite the undercut 213 on the upper side. In the illustrated embodiment, both gripping arms 1211 engage partially in each of these two undercuts 213. Since the undercuts 213 extend along the longitudinal axis of the crossbeams 212, the clamping element 121 can be positioned at any desired position along the longitudinal direction of the crossbeams 212 and clamped to the crossbeams 212 using the release mechanism 1220. Thus, the relative position of the connecting component 1 relative to the crossbeam 212 is continuously adjustable. In this way, it is ensured that a connection between the scaffold section 3 and the formwork panel 2 is always possible via the connecting component 1 in a direction that runs horizontally in the illustration.Possible differences in the horizontal grid between formwork panel 1 and scaffold section 3 do not impede the connection of the two components. As in . Fig. 2 As can be clearly seen, the clamping element is movable between at least two adjacent longitudinal struts 211 across the entire width of the transverse struts 212. The relative position between scaffold section 3 and formwork panel 2 can thus be individually adjusted to the requirements of the construction site. Furthermore, the clamping element 121 is very easy to operate thanks to the release mechanism 1220, and this can be done quickly.

[0069] In the detailed view in Fig. 2 A scaffold interface 11 is visible. This scaffold interface 11 is at least partially form-complementary to an interface on the vertical upright 51 of the scaffold section 3 shown on the left. Form-complementary here means that a portion of the scaffold interface 11 geometrically fits into a portion of an interface on the vertical upright 51. In the illustrated embodiment, the scaffold interface 11 is identical to an interface located on the adjacent horizontal ledger 52 of the scaffold section 3. Due to this similarity of the interfaces, the scaffold interface 51 of the connecting component 1 can be connected to the same interfaces on the vertical upright 51 as the horizontal ledgers 52. Thus, there are many different connection positions at which the connecting component 1 and the scaffold section 3 can be joined.This in turn provides a very flexible connection between formwork panel 2 and scaffold section 3. In the illustrated embodiment, connecting discs or rosettes are arranged on the vertical upright 51 as interfaces for connection with other scaffold elements. On the vertical upright 51 shown on the left, it is clearly visible that the scaffold interface 11 is connected to such a connecting disc on the left-facing side. Opposite this connection, the same connecting disc is connected to a horizontal beam 52. It is clearly visible that, at least in some areas, the connecting interface 11 and the interface with which the horizontal beam 52 is connected to the vertical upright 51 are identical. In the illustrated embodiment, the connecting component 1 includes a compensating element 14 which is arranged between the support element 13 and the scaffold interface 11.This compensating element 14 enables tolerance compensation or other positional adjustment in the vertical direction between the connecting component 1 and the scaffold section 3. For this purpose, the compensating element 14 has a linear bearing, which in this case comprises a round bolt running parallel to the longitudinal direction of the support element 13. A tubular element is inserted into this round bolt with clearance, so that it is movable relative to the round bolt in a direction that is vertical in the illustration. Along the length of the round bolt, the scaffold interface 11, which points away from the compensating element 14, can thus be moved vertically. This movement can also be used to connect the scaffold interface 11 to an interface on the scaffold section 3.Furthermore, this leveling element can compensate for differences in ground level that may exist between the ground beneath formwork panel 2 and the ground beneath scaffold section 3. Such a leveling element 14 is not strictly necessary, but it is helpful to further improve the connection between formwork panel 2 and scaffold section 3.

[0070] Fig. 3 Figure 1 shows a sectional view through a cross member 212 of a formwork panel 2, which belongs to an embodiment of the system according to the invention. Fig. 3 The crossbar 212 can be seen, which is in Fig. 2 The cross member 212 is connected to the formwork interface 12 of the connecting component 1. The cross member 212 is shown in a section cut in a plane perpendicular to its longitudinal direction. In the section to the left of the cross member 212, the formwork skin 22, which is connected to the frame 21, is also shown in section. The formwork skin 22 lies flat on the left-facing side of the cross member 212. In the background, a longitudinal member 211, which is connected to the sectioned cross member 212, is partially visible. The two gripping arms 1211 of the clamping element 121, which are positively and force-fit connected to the cross member 212, are also shown in the section. The cross member 212 is formed by a profile tube that has the shape of a bone.On both the upward-facing and downward-facing sides of the cross member 212 shown in the illustration, an undercut 213 is visible, which here is designed as a groove extending longitudinally along the cross member 212, i.e., into the plane of the drawing. The grooves forming the two undercuts 213 have an identical, rectangular cross-section. The two undercuts 213 are vertically symmetrical and arranged opposite each other on the cross member 212. The areas of the gripping arms 1211, which are in . Fig. 3 The gripping arms 1211 shown in the illustration are identical in design. Both gripping arms 1211 have a projection 1211a at their tip, which faces left in the illustration. This projection forms a section that engages in one of the undercuts in 213. In the illustrated embodiment, the lower of the two gripping arms 1211 is movable in a direction parallel to the formwork skin 22, thus allowing the distance between the two gripping arms 1211 to be adjusted. To create a connection between the formwork interface 12 and the formwork panel 2, the lower gripping arm is moved vertically downwards in the direction indicated by an arrow in the illustration, so that the distance between the two projections 1211a is greater than the width of the cross braces 212 in the vertical direction.The two gripping arms 1211 are then partially slid over the crossbars 212 until the projections 1211a are adjacent to the two undercuts 213. The lower gripping arm 1211 is then moved towards the upper gripping arm 1211, reducing the distance between them. In this process, the two projections 1211a engage in an undercut 213, creating a positive fit. With the two projections 1211a already positively engaged with the undercuts 213, the clamping element 121 can be moved parallel to the direction of the undercuts 213 along the crossbars 212 until the desired relative position between the clamping element 121 and the crossbar 212 is reached. The lower gripping arm 1211 is then moved towards the upper gripping arm 1211 until the two gripping arms 1211 clamp the crossbars 212.In this state, a force flow exists between the clamping element 121 and the cross braces 212. The described adjustability of the relative position of the clamping element 121 along the undercut 213 is particularly advantageous for a flexible connection between the connecting component 1 and the formwork panel 2. Such a connection can also be made between a clamping element 121 and a longitudinal brace 211. In the background, an undercut 213 is also arranged on the longitudinal brace 211 shown, which is aligned with the undercuts 213 of the cross brace 212.

[0071] Fig. 4 Figure 1 shows a perspective view of a second embodiment of a system 100 according to the invention. In this second embodiment, the system 100 also comprises a formwork panel 2, a scaffold section 3, and at least one connecting component 1. The distance between the formwork panel 2 and the scaffold section 3 is significantly greater here than in embodiment 1. Fig. 1 . which in Fig. 4 The illustrated embodiment is designed such that a wall element can be produced between the formwork skin 22 facing the scaffold section 3 and the scaffold section 3. A reinforcement B, shown here, is located between the formwork skin 22 and the scaffold section 3 and is already attached to the formwork panel 2. The reinforcement B is formed by several reinforcing meshes. In the illustrated embodiment, the connecting component 1 comprises a support element 13, the length of which is adjustable. The support element 13 is telescopic, meaning that a section of the support element 13 can be inserted into and removed from another section of the support element 13 to adjust the overall length. This allows the support element 13 to be used to adjust the distance between the scaffold section 3 and the formwork panel 2 to the wall element to be produced. Fig. 4 In the illustrated embodiment, the longitudinal direction of the support element of the 13 is essentially horizontal, whereas the longitudinal direction of the support element of the 13 is in Fig. 1 The formwork interface 12 of the connecting component 1 is connected here to the upward-facing edge of the formwork panel 2, as shown in the illustration. The formwork interface 12 encompasses this edge. In the illustrated embodiment as well, the formwork interface 12 includes a clamping element 121 with two gripping arms in 1211. For clarity, details of the clamping element 121 are shown in Fig. 4 Not shown. In the illustrated embodiment, at least one of the gripping arms 1211 is movable essentially perpendicular to the surface of the formwork skin 22. This allows a positive and force-fit connection between the clamping element 121 and the formwork panel 2 to be established, even in the illustrated embodiment. The connecting component 1 also includes a scaffold interface 11, which is connected here to a horizontal beam 52 of the scaffold section 3. This connection can be made, for example, via a clamp or clamping connection. The arrangement of the connecting component 1 in the illustrated second embodiment makes it possible to arrange another formwork panel 2 between the scaffold section 3 and the formwork panel 2 without this arrangement being obstructed by the connecting component 1.

[0072] Fig. 5 Figure 1 shows a perspective detail view of an embodiment of a formwork interface 12 of a connecting component 1 of a system not according to the invention. The connecting component 1 in the Fig. 5 The illustrated embodiment does not include a support element 13. In the illustrated embodiment, the clamping element 121 of the formwork interface 12 comprises an intermediate upright 122, which is formed by a pipe section with a round cross-section. The size and shape of the cross-section of the pipe section of the intermediate upright 122 correspond to the shape and size of a vertical upright 51 of the scaffold section 3. The two gripping arms 1211 and the release mechanism 1220 are arranged on the intermediate upright 122 and connected to a cross brace 212 of the formwork panel 2. A scaffold interface 11 is arranged on the intermediate upright 122. The relative position of the scaffold interface 11 and the intermediate upright 122 is adjustable, with at least three possible positions of the scaffold interface 11 on the intermediate upright 122 being provided. These three positions can be set by sliding the scaffold interface 11 on the intermediate upright 122 along its longitudinal direction.In the illustrated embodiment, both the scaffold interfaces 11 and the intermediate upright 122 have bores into which a plug-in element can be inserted to define the position of the components relative to each other. Thus, in the illustrated embodiment, the position of the scaffold interface 11 relative to the clamping element 121 is adjustable. This allows the connecting component 1 to be easily adapted to different applications. The scaffold interface 11 is identical in shape and size to an interface that is also used within the scaffold section 3, in particular on a vertical upright 51. Therefore, elements of the scaffold section 3, such as a [missing information], can be [missing information]. Fig. 5 The horizontal beam 52 shown is connected to the scaffold interface 11 in the same way as different scaffold elements are connected within the scaffold section 3. This is also the case in the Fig. 5 In the illustrated embodiment, the clamping element 121 comprises a release mechanism 1220, by which the connection between the gripping arms 1211 and the crossbar 212 can be easily and quickly established and released.

[0073] Fig. 6 Figure 1 shows a perspective detail view of a further embodiment of a formwork interface 12 of a connecting component 1 of a system not according to the invention. In this embodiment, one of the gripping arms 1211 is formed by a pin element 1212, which is inserted into a recess in a cross member 212 of the formwork panel 2. Fig. 6 This pin element 1212 is concealed and therefore not shown. A corresponding recess, suitable for receiving the pin element 1212, is shown on the right side adjacent to the clamping element. Here, the recess forms an undercut 213. In the illustrated embodiment, the second gripping arm 1211 is formed by a clamping element 1213. This clamping element 1213 partially encompasses the cross member 212 and rests against it. The clamping element 1211 also includes a clamping mechanism, which here comprises a threaded spindle and a handwheel. This clamping mechanism allows the relative position between the pin element 1212 and the clamping element 1213 to be changed. When the clamping element 1211 is attached to the cross member 212, the pin element 1212 is inserted into the recess, and then the clamping mechanism is actuated.This causes the pin element 1212 and the clamping mechanism 1213 to move towards each other, creating a positive and force-fit connection between the clamping element 121 and the cross brace 212. A support element 13 is arranged on the clamping element 121 and the scaffold interface 12. This support element 13 connects the formwork interface 12 to a scaffold interface 11. The scaffold interface 11 is designed here as a connecting clamp 1214, which is connected to a vertical upright 51 of the scaffold section 3. The connecting clamp 1214 grips the vertical upright 51 and is force-fitted to it by means of a screw connection. An advantage of this embodiment is that the scaffold interface 11, designed as a connecting clamp 1214, can be continuously moved along the vertical upright 51 and then force-fitted into position. This allows the relative position of the connecting component 1 to the scaffold section 3 to be adjusted very flexibly.It is also possible to arrange several scaffold interfaces 11 on the support element 13 if required.

[0074] Fig. 7 Figure 1 shows a perspective detail view of a further embodiment of a formwork interface 12 of a connecting component 1 of a system not according to the invention. In this embodiment of a connecting component 1, the relative position of the formwork interface 12 to the scaffold interface 11 is adjustable. The formwork interface 12 is designed as an compensating rail 1215. This compensating rail 1215 comprises a first section, which forms a gripping arm 1211 that is inserted into the undercut 213 in the cross member 212. This first section thus forms two flat bars arranged at an angle to each other, which are connected by a bolt oriented vertically in the illustration. This bolt is inserted into a cylindrical recess in the cross member 212, which forms an undercut 213.The second gripping arm 1211 is not shown in the illustration and is formed by a locking pin inserted into the vertically oriented bolt on the side located below the cross member 212 in the illustration. The compensating rail 1215 further comprises a second section, which is oriented towards the front right in the illustration. This second section is formed by a rail with a constant cross-section, which here has a rectangular cross-section. In this embodiment, the scaffold interface 11 is formed by a clamping bracket 1216, which is adjustably connected to the compensating rail 1215. For this purpose, the clamping bracket 1216 has a connection area that is partially form-complementary to the rail with the constant cross-section of the compensating rail 1215.The connection area encompasses the rail with a constant cross-section and is displaceable along the longitudinal axis of the rail with a constant cross-section. The clamping bracket 1216 also includes a locking element that can be inserted into the connection area and which, in the illustrated state, clamps the clamping bracket 1216 onto the rail with a constant cross-section. In this state, the locking element and the connection area completely enclose the rail with a constant cross-section. When connecting the scaffold interface 11 and the formwork interface 12, the connection area is first displaced relative to the compensating rail 1215 until the desired position of the formwork interface 12 and scaffold interface 11 is reached. The locking element is then inserted and this relative position is fixed. The clamping bracket 1216 also includes a connecting clamp 1214, which is firmly connected to the connection area.The connecting clamp 1214 is as shown in the [document / section]. Fig. 6 In the illustrated embodiment, the formwork panel 2 is positively connected to a vertical upright 51 of the scaffold section 3. The illustrated embodiment of a connecting component 1 is particularly advantageous because, firstly, the relative position between the formwork interface 12 and the scaffold interface 11 is adjustable, and secondly, the connecting clamp 1214 of the scaffold interface 11 is continuously adjustable in its position relative to a vertical upright 51. Thus, this embodiment of a connecting component 1 allows for adjustment of the position between the formwork panel 2 and the scaffold section 3 in two mutually perpendicular spatial directions.

[0075] The in Fig. 5 bis Fig. 7 All of the illustrated embodiments of a connecting component 1 can be used in a system 100. It is also possible to use several embodiments of a connecting component 1 together and in combination with each other in a system 100. Furthermore, it is possible to use one or more connecting components 1 according to the design shown in the illustrations in a system 100, alternatively and / or additionally. Fig. 1 and 2 to use the embodiments shown. The ones in the Fig. 1 , 2 , 5 , 6 und 7 The illustrated embodiments can therefore be combined with one another in any way in a system 100 according to the invention, thereby enabling a very high degree of flexibility with regard to the type and position of the connection between a formwork panel 2 and a scaffold section 3.

[0076] Fig. 8 shows a perspective view of a first state during the execution of a method according to the invention. Fig. 8 bis 10 Various states during the execution of a method according to the invention are depicted, which occur chronologically one after the other in the process. Fig. 8 The diagram shows a state in which, according to process step A), a temporary formwork has already been erected. This temporary formwork is composed of a total of twelve formwork panels 12, which are connected to each other. The temporary formwork is held in its vertically oriented position by a support M. Another support M is arranged on the rearward-facing side, which is, however, concealed by the formwork panels 2. The temporary formwork forms one half or side of a formwork unit required for the construction of a wall element. Starting from the position shown in the diagram, the diagram shows the following steps: Fig. 8 In the depicted state, reinforcement B will next be attached to the formwork, which will be fastened to the formwork. This attachment of the reinforcement can be carried out from a scaffold section (not shown) or with the aid of one or more working platforms.

[0077] Fig. 9 Figure 1 shows a perspective view of a second state during the execution of a method according to the invention. In the depicted state, reinforcement B has already been attached to the formwork. Furthermore, according to process step C), a system 100 was erected as a closing formwork opposite the formwork and the reinforcement B. The formwork panel 2 of the system 100 faces the reinforcement B and the formwork with its formwork skin 22, the formwork and the closing formwork together defining the area in which the wall element is to be produced. The scaffold section 3 is located on the side of the formwork panel 2 of the system 100 facing away from the formwork. In this way, the formwork panel 2 of the system 100 is easily accessible from the scaffold section 3 by persons located on the scaffold section 3. The system comprises several formwork panels 2, which are oriented parallel to each other and connected to one another.Starting from the one in . Fig. 9 In the depicted state, the formwork can now be prepared for pouring liquid concrete material according to process step D). For this purpose, anchors are inserted between the inset and closing formwork, which absorb the compressive forces acting on the formwork during the pouring of the wall element. These anchors can be conveniently installed from scaffold section 3. Furthermore, it is possible to carry out additional work to prepare the formwork from scaffold section 3. After the formwork has been prepared, liquid material is poured into the formwork according to process step E). This pouring can also be done from scaffold section 3. After the material has hardened according to process step F), the formwork can then be prepared for stripping. This preparation can again be carried out from scaffold section 3.During this preparation for stripping the formwork, for example, the anchors previously inserted between the formwork and the closing formwork are removed again.

[0078] Fig. 10 shows a perspective view of a third state during the execution of a method according to the invention. In the Fig. 10 In the depicted state, formwork panel 2 has already been separated from scaffold section 3 of system 100 according to process step G). Furthermore, formwork panel 2 has been separated from the now hardened and self-supporting wall element W. To separate formwork panel 2 from scaffold section 3, the scaffold interfaces 11 of the connecting components 1 were detached from scaffold section 3. It can be seen that the connecting components 1 are still connected to formwork panel 2 via the formwork interfaces 12 and are removed together with it. Alternatively, it is also possible to disconnect the connection between the formwork interfaces 12 under formwork panel 2, in which case the connecting components 1 remain connected to scaffold section 3. Alternatively, the connections of the formwork interfaces 12 and the scaffold interfaces 11 can be disconnected, and the connecting components 1 can be separated from both scaffold section 3 and formwork panel 2.The removal of formwork panel 2 of system 100 is carried out here in a vertical direction, parallel to the constructed wall element W and to scaffold section 3. Formwork panel 2 can be removed, for example, using a crane that lifts it upwards. During and after the removal of the formwork panel according to process step H), scaffold section 3 remains in an unchanged position parallel to the constructed wall element W. Before or after the removal of formwork panel 2 of system 100, the temporary formwork is also removed from the constructed wall element W. In the illustrated state, the temporary formwork with its support M extended has been detached from the wall element W and moved to the rear left. The temporary formwork can also be removed from the wall element using a crane.After the removal of the formwork and closing formwork, further work on the produced wall element W can be carried out from scaffold section 3 without the need for prior work to erect additional scaffolding or a further work platform. Scaffold section 3 is already positioned so that tasks such as filling holes left by the anchors can be performed from it. The finishing or post-processing of the produced wall element W can therefore begin immediately after the removal of formwork panel 2, thus simplifying the wall element manufacturing process compared to the prior art and making it faster.

[0079] Fig. 11 shows a perspective view of a first state during the execution of an alternative method according to the invention. Fig. 11 bis 13 Various states occurring sequentially during the execution of an alternative method for manufacturing a wall element are depicted. The alternative method differs from the previously described method in that the distance between formwork panel 2 and scaffold section 3 of system 100 is greater, and the wall element is manufactured between formwork panel 2 of system 100 and scaffold section 3. Fig. 11 The diagram shows a state in which system 100 has already been assembled according to process step I) and forms a temporary formwork. A total of three connecting components 1 connect the formwork panel 2 to the scaffold section 3. The formwork skin 22 faces the scaffold section 3. The wall element will later be produced in the space between the formwork panel 2, in particular the formwork skin 22, and the scaffold section 3. In the Fig. 11 In the depicted state, reinforcement B was already attached to the formwork panel 2 in accordance with process step II). This attachment of the reinforcement B was carried out by persons who were on the scaffold section 3. An advantage of this embodiment is that the scaffold section 3 supports and positions the formwork panel 2 of the formwork system, so that no support M, as in Fig. 8 bis 10 , is required. At the same time, scaffold section 3 can already be used for attaching the reinforcement B to the formwork.

[0080] Fig. 12 Figure 1 shows a perspective view of a second state during the execution of an alternative method according to the invention. Fig. 12 In the depicted state, another formwork panel 2 was erected as closing formwork between the already erected formwork panel 2 of system 100 and scaffold section 3. This additional formwork panel 2 was swung into place from above between the already erected formwork panel 2 and scaffold section 3 using a crane and connected to scaffold section 3. The positioning formwork and the closing formwork together define the area in which the wall element is to be manufactured and in which the reinforcement B has already been installed. In the Fig. 12 In the depicted state, personnel located on scaffold section 3 can now prepare the formwork for the pouring of liquid concrete material according to process step IV). This preparation can include, for example, inserting anchors between the formwork and the closing formwork. After the formwork has been prepared, liquid material is poured into the formwork according to process step V), and the poured material is cured according to process step VI) until the wall element W itself is load-bearing. Pouring the material into the formwork and monitoring the curing process can also be carried out from scaffold section 3.

[0081] Fig. 13 shows a perspective view of a third state during the execution of an alternative method according to the invention. Fig. 13 The diagram shows a state that occurs during the execution of process step VII), in which the formwork panel 2 is separated from the scaffold section 3. For this purpose, the connecting components 1 have already been dismantled, whereby both the formwork interface 12 and the scaffold interface 11 have been separated from the formwork skin 2 and the scaffold section 3, respectively. The formwork panel 2, which forms the closing formwork, is in the Fig. 13The formwork shown is removed vertically upwards, for example, using a crane. The formwork panel 2, which forms the temporary formwork, is symbolically offset backwards from the wall element W. The temporary formwork can also be removed vertically upwards using a crane. After the removal of the temporary and closing formwork, scaffold section 3 remains in its original position parallel to the manufactured wall element W. Thus, according to process step IX), post-processing or finishing of the manufactured wall element W can be carried out from this scaffold section 3. In this alternative method as well, scaffold section 3 is used for several different tasks performed sequentially during the production of the wall element W. This simplifies the process for manufacturing the wall element W and allows it to be carried out in less time. Reference symbol list:
