METHOD FOR PRODUCING A WALL ELEMENT

Description

[0001] The present application claims priority from German patent application No. 10 2021 120 441.0.

[0002] The invention relates to a method using a system for formwork of a wall element, comprising at least one formwork panel, at least one connecting component and at least one scaffolding section, wherein the connecting component comprises at least one scaffolding interface which is provided for detachable connection to the one scaffolding section and at least one formwork interface which is provided for detachable connection to the formwork panel. The at least one connecting component is connected to the scaffolding section with its scaffolding interface and the connecting component is connected to the at least one formwork panel with its formwork interface. When the system is assembled, the scaffolding section supports and positions the formwork panel and the system can be used freestanding. The invention further relates to a method for producing a wall element using such a system.

[0003] The invention relates to the field of construction. When erecting or renovating buildings, building components are often formed by pouring concrete. The shape of these cast building components is predetermined by formwork, which is erected on site prior to pouring. In particular, ceilings or walls of a building are erected with the aid of formwork. When constructing high walls or wall elements, scaffolding is required to prepare the formwork for the manufacture of the wall element. Scaffolding is required, on the one hand, to connect individual formwork panels to one another to form the overall formwork, for example by attaching formwork locks. Furthermore, two opposing formwork panels must be connected to one another by anchors before a wall element is constructed in order to absorb the outward pressure of the poured concrete material.To do this, the formwork panels must be accessible to workers across their entire height, which is usually achieved using scaffolding or a work platform. Furthermore, in most cases, reinforcement must be attached to an already positioned temporary formwork or between such a temporary formwork and a closing formwork opposite the temporary formwork before the wall element is manufactured. According to the state of the art, scaffolding or work platforms intended for attaching formwork locks are arranged on the formwork in such a way that reinforcement cannot be attached from these scaffolds or work platforms. The points where the reinforcement must be positioned are simply not accessible from the scaffolding or work platforms used to prepare the formwork panels, as they are located on the opposite side of the formwork panel.In practice, this means that a first type of scaffold is required to operate the formwork, and a second type of scaffold is required to position and insert the reinforcement into the formwork. In addition, there are usually a variety of different types of scaffolding and formwork panels on site, which means that the scaffolding and formwork panels can often not be connected, especially for the applications described above. Differences in the grid that exist between the scaffolding systems and the formwork systems usually prove to be problematic. Finally, in many applications, after a wall element has been poured using the formwork, further work still needs to be carried out on the wall element after the formwork has been removed, for example filling anchor holes or plastering or painting.In order to reach the entire height of the wall element, a scaffold or work platform is required after the actual pouring to carry out the final work. Therefore, the production of a wall element using formwork requires a multitude of different scaffolds or work platforms, resulting in complicated work processes and the need for a variety of different scaffolding elements. Methods for producing wall elements using formwork and scaffolding are known, for example, from JP2015212495A or US 5 575 938 A.

[0004] The object of the invention is therefore to propose solutions with which the production of a wall element can be simplified.

[0005] This object of the invention is achieved by a method according to claim 1.

[0006] The system comprises at least one formwork panel, at least one scaffolding section and at least one connecting component which connects the formwork panel to the scaffolding section. The connecting component enables a connection, in particular a statically load-bearing connection, between the formwork panel and the scaffolding section. The connecting component allows the formwork panel and the scaffolding section to be easily connected to one another, whereby the connection and the separation of this connection can be carried out simply and quickly. A system according to the invention usually comprises several formwork panels and can also comprise more than one scaffolding section. For the connection, several connecting components are usually provided which are arranged at different positions between the formwork panel(s) and the scaffolding section.

[0007] The scaffolding section of the system is formed by a scaffolding section according to the state of the art and comprises several vertical posts that are essentially vertically oriented when erected and several horizontal bars that are essentially horizontally oriented when erected. These elements of the scaffolding section are connected to one another and, when erected, form a scaffolding section extending in three spatial directions. The scaffolding section can comprise additional elements, such as treads, ladders, railings, and the like. The scaffolding section is preferably modular in design, meaning that the scaffolding section can be constructed from standard elements in different sizes and shapes. The scaffolding section can, for example, be a so-called system scaffold.

[0008] The system 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 lattice shape, with a plurality of longitudinal struts which are oriented essentially vertically when assembled and a plurality of cross struts which are oriented essentially horizontally when assembled forming this frame. The longitudinal struts and the cross struts are oriented at right angles to one another. The formwork skin is fastened to the frame and rests on at least some of the longitudinal struts and cross struts. As a result of this resting, forces acting from the concrete material on the formwork skin during the manufacture of a wall element are diverted into the supporting frame of the formwork panel. At least some of the longitudinal struts and / or the cross struts have an undercut.An undercut is an area that is set back from adjacent areas. If a counter element is connected to the frame of the formwork panel in such a way that it engages partially in the undercut, a positive connection is created through which the counter element is connected to the frame. The undercut is intended to create a positive and force-fitting connection with a formwork interface of a connecting component, which will be described later. The undercut extends in the longitudinal direction of the longitudinal struts and / or cross struts. For example, the undercut can be formed by a groove that is set back from the remaining surface of the longitudinal struts and / or cross struts and that extends along these struts.This longitudinal extension of the undercut allows a connecting component to be attached to the formwork skin at a variety of positions. This variability in the position at which a connecting component can be connected to the frame means that formwork panels and scaffold sections with different grids can be connected very easily. The longitudinally extending undercut allows a connection to be made at virtually any position, meaning the grid used for the formwork panel or the formwork system between multiple formwork panels is irrelevant for the connection to the connecting component. Preferred embodiments of the undercut will be described later.

[0009] The system further comprises at least one connecting component with a scaffolding interface and a formwork interface. The formwork interface is provided 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 designed to be movable relative to one another. The distance from one gripping arm to the other is variable or adjustable. The gripping arms of the clamping element are designed to engage, at least in some areas, in the undercut in the frame of the formwork panel and thus create a positive connection between the connecting component and the formwork panel. In addition to the gripping arms, the clamping element can 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 created by first adjusting the two gripping arms so that they can partially grip a cross strut or a longitudinal strut of the frame. In this state, the gripping arms are partially pushed over the longitudinal strut or the cross struts until an area of ​​the gripping arms is positioned adjacent to one or more undercuts on the cross strut or the longitudinal strut. The distance between the two gripping arms is then reduced, with the latter engaging at least partially in the undercut on the frame. This creates the previously described positive connection between the connecting component and the frame of the formwork panel. Preferably, this connection simultaneously creates a force-fitting connection, in particular a clamping between the gripping arms and the frame.Such a force-locking connection ensures that there is no play between the connecting component and the formwork panel, thus creating a stable connection that can withstand static and dynamic loads. A particularly advantageous feature of this connection is that it can be created at various positions along the length of the cross brace or the longitudinal brace. This means that the connecting component can be variably positioned relative to the frame of the formwork panel. Advantageously, the undercut extends over the entire free length of the cross braces and the longitudinal braces. This allows a connection to the connecting component at almost any location on the frame of the formwork panel. Only at the intersection points of the longitudinal braces and the cross 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 so that it can be easily made and broken. When the system is assembled, when the connecting component connects the formwork panel and the scaffolding section, the system is free-standing. Free-standing means that the system stands firmly on the ground and will not fall over. In addition, the scaffolding section of the free-standing system can be accessed by people and used for work. The scaffolding section supports the formwork panel and vice versa. At the same time, the scaffolding section positions the formwork panel, for example within a formwork or a formwork system for producing a wall element. The system is designed so that it can preferably be used without additional support elements such as props.The system according to the invention thus avoids the effort required to attach additional support elements for erecting and positioning the formwork panel. The connection of the formwork panel and the scaffolding section by the connecting component also makes it possible to transport and position the entire system together. For example, the assembled system can be positioned using a crane at the location where it is needed to manufacture the wall element. This eliminates the need to assemble the system at the site where the wall element is to be created. It is also possible to remove the system according to the invention in one piece or in the assembled state after the wall element has been manufactured, or to change its alignment and position relative to the produced wall element. For example, the system can be rotated by 180°, whereby the opposite side of the system faces the wall element that has been produced or is to be produced.Even in this rotated position, the system can be used freestanding for any work that may arise.

[0010] The system 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 enables a simple and flexible connection. Preferably, several connecting components mounted 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, allowing a system according to the invention to be provided easily and cost-effectively using an existing scaffolding section. Existing equipment can thus be advantageously converted to a system according to the invention. The scaffolding section can be used for multiple tasks, for example, for attaching reinforcement to or in the formwork and for safely pouring the concrete material into the formwork. Thus, a system according to the invention saves effort and working time in the manufacture of a wall element, which is achieved through the multiple use of a single scaffolding section. The system according to the invention is thus particularly suitable for the manufacture of a wall element. Furthermore, the system according to the invention can of course also be used for the manufacture 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 complementary in shape to an element of the formwork panel. "Complementary in shape" here means that an area of ​​the clamping element, in particular the tip area of ​​the gripping arms, has a negative shape for undercutting the frame of the formwork panel. This ensures a secure form fit between the formwork interface and the formwork panel.

[0012] Furthermore, it is provided that the scaffolding interface is designed to be at least partially complementary in shape to an interface on the scaffolding section. By complementary in shape is meant here that at least a partial area of ​​the scaffolding interface has a negative shape to a partial area at an interface on the scaffolding section. The scaffolding section has interfaces for connecting its components, for example vertical posts and horizontal bars. Preferably, a partial area of ​​the scaffolding 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 scaffolding section. For example, connecting disks with recesses can be arranged on a vertical post of the scaffolding section, into which interface elements of a horizontal bar can be inserted in a form-fitting manner.In this case, the scaffolding interface of the connecting component can be designed to correspond to the interface on the horizontal ledger. In this way, the scaffolding interface can be connected to a vertical post in the same way as a horizontal ledger of the scaffolding section. This embodiment allows the connecting component to be easily attached to various positions on the scaffolding section. Alternatively, the connecting component can also be designed such that it simultaneously forms a component of the scaffolding section while functionally combining the two. In this alternative embodiment, the scaffolding interface is also identical to or very similar to an interface used in the scaffolding section and is shape-compatible with a corresponding interface in the scaffolding section.

[0013] In an advantageous embodiment, a support element is provided which is connected to the formwork interface and the scaffolding interface, in particular wherein the support element is rod-shaped, wherein the formwork interface and the scaffolding interface are arranged at a distance from one another on the support element. In this embodiment, a support element is provided which connects the formwork interface and the scaffolding interface to one another. The support element can have various shapes. Preferably, the support element is rod-shaped and can be formed, for example, by a tube or a tube section. The distance between the formwork panel and the scaffolding section can be adjusted when the system is in the assembled state by the distance at which the formwork interface and the scaffolding interface are arranged from one another on the support element.To allow for individual adjustment of the distance between the formwork panel and the scaffolding section, the support element can also be designed to be adjustable in length, for example, telescopic. The scaffolding interface and the formwork interface can be rigidly connected to the support element, or their position and alignment can be adjustable.

[0014] It is preferably provided that the support element has a longitudinal axis and the formwork interface and the scaffolding interface are arranged at a distance from one another along the longitudinal axis, and wherein the longitudinal axis is oriented substantially parallel to the surface of the formwork facing or substantially perpendicular to the surface of the formwork facing. In this embodiment, the support element has a longitudinal axis which runs between the formwork interface and the scaffolding interface. Preferably, the connecting component is oriented to the formwork panel such that the longitudinal axis runs substantially parallel to the surface of the formwork facing or substantially perpendicular to the surface of the formwork facing. However, the orientation of the longitudinal axis relative to the surface of the formwork facing can also be at a different angle.

[0015] In one embodiment, it is provided that the support element comprises a vertical post which is designed substantially identically to a vertical post of the scaffolding section, wherein at least one formwork interface is fastened to the vertical post and the scaffolding interface is designed substantially identically to an interface which the vertical post of the scaffolding section has, in particular wherein a plurality of spaced-apart scaffolding interfaces are arranged on the support element comprising the vertical post. In this embodiment, the support element comprises a vertical post or is formed by a vertical post. Thus, the support element can be integrated directly into the scaffolding section. In contrast to the other elements of the scaffolding section, however, the support element has at least one formwork interface which is connected to the formwork skin.The advantage of this embodiment is that at least one vertical post, which must be provided additionally in other embodiments, is formed by the connecting component in this alternative embodiment. In this way, the number of parts required for the system and in particular for the scaffolding section is reduced. Preferably, the vertical post, which forms the support element, is provided with a plurality of scaffolding interfaces for connecting to other components of the scaffolding section. This corresponds to known vertical posts of a scaffolding section, which usually also have a plurality of interfaces for connecting to other components of a scaffolding section. The vertical post, which forms the support element, can, however, be designed differently from another vertical post in some regions.For example, additional fastening surfaces or fastening elements can be provided for attaching one or more formwork interfaces.

[0016] Advantageously, a compensating element is provided which is arranged between the support element and the scaffolding interface, wherein the compensating element has a linear bearing by means of which the scaffolding interface and the support element can be displaced relative to the support element, at least in some regions, in a direction parallel to the longitudinal axis of the support element. In this embodiment, a compensating element is provided which enables a displacement between the scaffolding interface and the support element and thus also a displacement between the scaffolding interface and the formwork interface. For this purpose, the compensating element has a linear bearing which guides a linear movement in a direction parallel to the longitudinal axis of the support element. This displaceability between the scaffolding interface and the formwork interface further increases the flexibility of the connection between the formwork facing and the scaffolding section.The adjustable distance between the two interfaces allows for continuous adjustment, compensating for tolerance differences or grid spacing between the scaffold section and the formwork panel. Furthermore, the compensation element also allows for height differences in the system's substructure to be compensated. 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 using the compensation element without requiring any adjustments to the system.

[0017] Furthermore, it is provided that the distance between the scaffolding interface and the formwork interface, in particular in a direction perpendicular to the longitudinal axis of the support element, is greater than or equal to the thickness of the formwork panel. The distance between the scaffolding interface and the formwork interface defines the distance between the formwork panel and the scaffolding 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 facing. However, this distance can also be smaller. Furthermore, the distance can also be chosen to be significantly greater; for example, the distance between the scaffolding interface and the formwork interface, in particular in a direction perpendicular to the longitudinal axis of the support element, can also be greater than three times the thickness of the formwork panel, or greater than five times the thickness of the formwork panel.

[0018] In a further embodiment, two scaffolding interfaces and two formwork interfaces are provided, which are each arranged at a distance from one another on a common support element. In this embodiment, two scaffolding 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 post of the scaffolding section in the system. The length of the support element is at least 1 m. Two scaffolding interfaces are arranged on the support element pointing in a first direction, which are or are connected to interfaces on the scaffolding section.On a second, opposite side, two formwork interfaces are also arranged, which are connected to the frame of the formwork panel. Such a connecting component enables a two-point connection to the formwork panel and to the scaffolding section. The connecting component is thus more stable and has a higher load-bearing capacity. Furthermore, the number of components required to assemble a system is reduced by such a connecting component, simplifying logistics on the construction site and reducing the system's assembly time.

[0019] Cleverly, it is provided that the clamping element of the two formwork interfaces, which are arranged on a common support element, has a release mechanism which can be actuated by a simple linear or rotary movement, wherein the positive connection between the formwork interface and the formwork panel can be released by actuating the release mechanism. In this embodiment, the clamping element has a release mechanism which can be operated quickly and easily by hand. This allows the formwork interface of the connecting component to be quickly and easily separated from the formwork panel. This is advantageous if, during the manufacture of a wall element, the formwork panel is to be separated from the scaffolding section when the system is dismantled. The release mechanism makes such a 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 comprise a rod-shaped lever that is actuated in a linear or rotary movement, thereby releasing the positive 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 is actuated. Such an unlocking mechanism is preferably used in a connecting component that has two or more formwork interfaces. Such a connecting component is described in the previous embodiment.It can be provided that a common release mechanism is provided for several formwork interfaces, or each formwork interface has its own release mechanism, with the release mechanisms being coupled to one another. In this way, several formwork interfaces can be simultaneously separated from the formwork panel with a single actuation process. This further reduces the time required to separate the formwork panel and the scaffold section. Of course, it is also possible to provide a release mechanism for embodiments of a connecting component that has only one formwork interface.

[0020] In a further embodiment, it is provided that the direction of movement of at least one of the gripping arms of the clamping element is oriented substantially parallel to the connecting direction of the scaffolding interface and / or substantially parallel to the surface of the formwork facing. The distance between the two gripping arms of the clamping element is adjustable, with at least one of the gripping arms being designed to be movable. In one embodiment, at least one of these gripping arms is movable in a direction which, when the system is disassembled, runs substantially parallel to the surface of the formwork facing. In this way, the movement of the gripping arm can at least partially encompass a longitudinal strut or a transverse strut of the frame of the formwork panel. The direction of movement of the gripping arm is understood to be the direction along which the distance between the two gripping arms is designed to be adjustable.The clamping element can also be designed so that both gripping arms are movable. Preferably, the direction of movement of the gripping arm is parallel to a connection direction of the scaffolding interface. This connection direction is the direction in which the scaffolding interface is moved to establish or release a connection with the scaffolding section. The connection direction can be oriented parallel to a vertical post of the scaffolding section, i.e., essentially vertically when the system is assembled. In this case, the direction of movement of the gripping arm is also essentially vertical, enabling the clamping element to grip a cross brace of the formwork panel.

[0021] In an alternative embodiment, it is provided that the direction of movement of at least one of the gripping arms of the clamping element is oriented substantially perpendicular to the connecting direction of the scaffolding interface and / or perpendicular to the surface of the formwork facing. In this embodiment, the direction of movement of a 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 runs perpendicular to the surface of the formwork facing. This enables the clamping element to engage around an edge region of the frame of the formwork panel. This enables the connecting component to be arranged at the edge of the formwork panel, which, for example, enables the arrangement of a second formwork panel between the formwork panel and the scaffolding section. When the system is assembled, the direction of movement is preferably horizontal.Thus, the direction of movement is oriented essentially perpendicular to a connection direction of the scaffold interface, which preferably runs in the vertical direction.

[0022] 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. 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 designed to be telescopic. The support element can also have at least one locking device with which a set length of the support element can be securely fixed.

[0023] In an advantageous embodiment, the undercut on the frame of the formwork panel is designed as a groove which is oriented in the longitudinal direction of the longitudinal struts and / or cross struts, wherein the groove has a U-shaped, rectangular or curved cross-section. The undercut can be designed as a groove which is introduced into the longitudinal struts and / or cross struts and which extends, at least in regions, along these struts. Preferably, the longitudinal struts and the cross struts have a rectangular cross-section, wherein the formwork skin rests on a side surface of this rectangular cross-section. The undercut is preferably arranged on a side surface which is adjacent to the side surface on which the formwork skin rests. Two undercuts can also be arranged on a cross strut or longitudinal strut, which are preferably arranged on two opposite side surfaces of the struts.In cross-section, such an undercut designed as a groove can have a U-shaped, rectangular, polygonal, or semicircular shape. In general, 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 cross member or longitudinal member.

[0024] In a further embodiment, at least two connecting components are provided, each connecting component having at least two formwork interfaces, and the formwork panel having a plurality of cross struts with an undercut arranged thereon at least in some regions, wherein the distance between the at least two formwork interfaces on the connecting component corresponds to an integer multiple of the distance between two adjacent cross struts of the formwork panel. In this embodiment, the grids of the formwork panel and the connecting component are coordinated with one another, thus enabling flexible use of the components of the system. Each connecting component has two formwork interfaces, which are arranged at a distance from one another on a supporting element. The distance between the two formwork interfaces on the supporting element corresponds to an integer multiple of the distance between two cross struts of the formwork panel.The distance between two adjacent cross braces of the formwork panel is smaller than the distance between the two formwork interfaces on the connecting component. This choice of dimensions allows the connecting component to be connected to different cross braces of the formwork panel at different positions. When the system is assembled, the connecting component can therefore be arranged at different heights in the vertical direction relative to the formwork panel. 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 the areas of the combined formwork where two formwork panels meet, it may not be possible to attach the formwork interface.In this case, the connection with the connecting component can be offset from the points where two formwork panels meet. Thus, connecting a scaffold section to a formwork panel using the connecting component is possible even if the overall size or shape of the formwork and / or scaffold section is varied.

[0025] Advantageously, the formwork panel and the scaffold section are oriented parallel to each other, with the distance between the formwork panel and the scaffold section being determined by the connecting component. Such a parallel arrangement of the formwork panel and scaffold section is particularly advantageous when producing a wall element, since the formwork or 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.

[0026] Furthermore, it is provided that the connecting component forms a vertical post of the scaffolding section in functional combination, and the scaffolding interface is formed by at least one interface which corresponds in shape and size to a connecting interface within the scaffolding section. In this embodiment, the connecting component can be integrated into the scaffolding section like a vertical post and assumes a supporting function within the scaffolding section. The connecting component is designed, at least in some regions, identical to a vertical post as used within the scaffolding section. In this way, the connecting component, in functional combination, simultaneously forms an element of the scaffolding section, thereby eliminating the need for a vertical post in the scaffolding section. This reduces the number of components or parts required for the system.In this embodiment, the scaffolding interface corresponds to an interface that also has a vertical post in the scaffolding section. The length and the grid in which the connection interfaces are arranged on the connecting component also correspond to the dimensions of a vertical post in the scaffolding section.

[0027] In one embodiment, the clamping element has a release mechanism that is operatively connected to the movable gripping arm. The release mechanism can be operated manually or with a simple hand tool and generates a relative movement of the movable gripping arm to another gripping arm. This embodiment builds on the previously described embodiment, in which the connecting component, in functional combination, forms a vertical post of the scaffolding section. An unlocking mechanism is arranged on this vertical post and serves to actuate the clamping element of the connecting component. By actuating this unlocking mechanism, the connecting component can be quickly and easily connected to or separated from the formwork panel.Preferably, the release mechanism is designed so that the formwork panel and scaffold section can be easily connected when the formwork panel is placed on the subsurface or ground with the formwork facing. This also allows the scaffold section to be erected in a horizontal position, which offers advantages in terms of occupational safety.

[0028] Furthermore, it is advantageously provided that the clamping element comprises a tenon element and a tensioning element, wherein the tenon element is positively inserted into a recess, in particular into a bore, in one of the longitudinal struts or the transverse struts of the formwork panel and the tensioning element is designed to be movable relative to the tenon element and the tensioning element bears at least partially against one of the longitudinal struts or the transverse struts, wherein a tensioning mechanism is provided which generates the relative movement between the tenon element and the tensioning element and wherein the tensioning mechanism generates a positive and a non-positive 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.A tenon element is provided on the clamping element, which is inserted into the recess in the frame during connection in a form-fitting manner. The tenon element has a negative shape to the recess in some areas and forms a movable gripping arm of the clamping element. In this embodiment, the second gripping arm is formed by a tensioning element, which rests against a longitudinal strut or a cross strut when connected to the frame and partially encloses it. A tensioning mechanism is arranged between the tenon element and the tensioning element, which creates a relative movement between the two elements or gripping arms. By actuating the tensioning mechanism, the distance between the tenon element and the tensioning element is reduced, thereby establishing a flow of force and a form-fitting connection between the scaffolding interface and the frame of the formwork panel.

[0029] Cleverly, it is provided that the scaffolding interface, which is arranged at a distance from the formwork interface on a support element, is designed as a connecting clamp, wherein the connecting clamp is non-positively attached to a vertical post of the scaffolding section. In this embodiment, the scaffolding interface is designed as a connecting clamp which is non-positively and positively connected to a vertical post of the scaffolding section. This connection point can be positioned almost arbitrarily on the vertical post. In this embodiment, the scaffolding interface is therefore not identical to an interface which is used to connect components within the scaffolding section. The connecting clamp encloses a vertical post in the circumferential direction and is clamped at the desired connection position, for example using a screw connection.A scaffolding interface designed as a connecting clamp offers the advantage of being particularly flexible in terms of the relative position between the connecting component and the scaffolding section. This design also allows for the compensation of tolerances or differences in the height of the substructure beneath the formwork panel and the scaffolding section between the connecting component and the scaffolding section.

[0030] In an alternative embodiment, it is provided that the formwork interface is formed by a compensation rail and the scaffolding interface by a clamp, wherein the compensation rail is introduced with a first partial area, which forms a gripping arm, into the undercut in the frame of the formwork panel, wherein the second gripping arm is formed by a locking pin, which can be introduced into the first partial area and the compensation rail has a second partial area, which is designed as a rail with a constant cross-section and the clamp has a connection area, which is at least partially designed to be complementary in shape to the compensation rail and the clamp further has a locking element, which can be introduced into the connection area and in the connected state, the connection area and the locking element together completely enclose the compensation rail,The clamp is designed to be displaceable parallel to the longitudinal direction of the compensating rail, and the clamp further comprises a connecting clamp arranged adjacent to the connection area, the connecting clamp being non-positively fastened to a vertical post of the scaffolding section. In this embodiment, the formwork interface is designed as a compensating rail. A formwork interface designed in this way comprises a first partial area, which is positively inserted into 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 partial area 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 the connection, the first section is guided through the undercut in the frame, and then the locking pin is inserted into the part that extends beyond the longitudinal strut or the transverse strut. In this way, the formwork interface is positively connected to the frame of the formwork panel. Adjacent to the first section, the compensation 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. The provision of the second sub-area as a rail with a constant cross-section improves flexibility with regard to the relative position between the formwork panel and the scaffolding section. Using this rail with a constant cross-section, the relative position between the formwork interface and the scaffolding interface in the connecting component can be varied along the length of this rail. Thus, in this embodiment, not only is there variability with regard to the attachment of the connecting component to the formwork panel and the scaffolding section, but there is also additional variability or adjustability within the connecting component. This embodiment is particularly advantageous,if the formwork panel has undercuts on its frame only at discrete points. Such formwork panels are often in the inventory of construction companies and are intended to be reused in the future. Using a connecting component according to this embodiment, such formwork panels from older stock can be used very flexibly in a system. The adjustability of the scaffold interface relative to the formwork interface is further enabled by the connection area of ​​the clamp, which in this embodiment forms the scaffold interface. This connection area is at least partially designed to complement the shape of the second section of the compensation rail. This means that the connection area encompasses a section of the compensation rail. To firmly connect the scaffold interface to the formwork interface, the clamping point also has a locking element.which can be inserted into the connection area and, together with the connection area when connected, completely encompasses the constant-cross-section rail. The locking element is designed in such a way that a frictional connection can also be created between the clamping point and the compensation rail. During the connection, the connection area is first pushed over the second section of the compensation rail. In this state, the connection area can be moved relative to the compensation rail along the length of the constant-cross-section rail, allowing the position between the formwork interface and the scaffold interface to be adjusted. The locking element is then inserted into the connection area.This creates a positive and a frictional connection between the components. In this state, the connecting component is then fixed. As in the previously described embodiment, the scaffold interface is connected to the scaffold section via a connecting clamp, which, when connected, encloses a vertical post of the scaffold section and is frictionally fastened to it. As previously described, this connecting clamp is advantageous here because it can be positioned almost continuously relative to a vertical post of the scaffold section. The described embodiment thus offers a very high degree of adaptability with regard to the shape and positioning of the connecting component between formwork panels and scaffold sections.

[0031] The method according to the invention, according to claim 1, for producing a wall element comprises the steps A) Erecting a formwork system comprising at least one formwork panel, B) Erecting the system parallel to the formwork system, with the scaffolding section facing the formwork system, C) Fastening reinforcement to the attached formwork system, with the reinforcement being fastened from the scaffolding section, D) Rotating the system until the formwork panel and the formwork system delimit the spatial area in which the wall element is provided, with the reinforcement being arranged between the formwork system and the formwork skin, and with the scaffolding section being arranged on the side of the formwork system opposite the formwork system, E) Preparing the formwork for the filling of a liquid material between the formwork system and the closing formwork, in particular inserting anchors which connect the formwork system and the closing formwork system, F) Filling the formwork with a liquid material, G) Curing the material,which together with the reinforcement forms the wall element, H) Removal of formwork and system. ,

[0032] The method according to the invention serves to produce a wall element, for which purpose a system according to one of the previously described embodiments is used. Thus, the use of a system according to one of the previously described embodiments for producing a wall element is also disclosed. The method according to the invention can of course also be used to produce other structural components, such as columns or pillars, although this does not constitute part of the present invention. The method is preferably carried out in the described order of method steps A) to H). However, it is also possible to carry out the method steps in a different order.

[0033] In a first method step A), a formwork assembly is constructed, comprising at least one formwork panel. The formwork assembly can be formed by a known formwork panel. Preferably, several formwork panels are combined to form a formwork assembly. It is also possible to use a system according to the invention as the formwork assembly.

[0034] In a second process step B), a system is assembled according to one of the previously described embodiments, with the surface of the formwork skin of the system preferably oriented parallel to the surface of the already assembled formwork. In process step B), the system is positioned so that the scaffold section faces the formwork and the formwork panel faces away from the formwork.

[0035] In a third process step (C), reinforcement is attached to the formwork. This work is carried out from the scaffolding section of the system. It is advantageous that the scaffolding section runs parallel to the formwork, making it easily accessible from all points of the scaffolding. Since the reinforcement is attached from the scaffolding section of the system, no additional reinforcement scaffolding is required in this process step. After this work is completed, the workers leave the scaffolding section.

[0036] In a fourth process step D), the system is rotated in order to use it as a closing formwork. The system is rotated 180° around a vertical, fictitious axis until the surface of the formwork facing of the system points towards the surface of the formwork facing of the temporary formwork and preferably runs parallel to it. In this rotated state, the previously erected temporary formwork and the system serving as the closing formwork delimit the spatial area in which the wall element is to be created and in which the reinforcement is also arranged. In the rotated state, the scaffolding section of the system points away from the temporary formwork and the spatial area in which the wall element is to be created. The advantage of this is that the system does not need to be supported by additional mechanisms; instead, the formwork panel of the system is supported and held in position by the connected scaffolding section.The closing formwork can thus be positioned and secured by simply rotating the system. This rotation of the system is preferably carried out using a crane, which, after completing process step C), lifts the system, rotates it 180° in the raised position, and then lowers it vertically again.

[0037] In a fifth process step E), the formwork is prepared for the pouring of a liquid material, preferably a concrete material, between the temporary formwork and the closing formwork. For this purpose, anchors can be attached to or in the formwork, for example, which connect the temporary formwork to the closing formwork and absorb and compensate for outward compressive forces acting on the formwork during the pouring of the wall element. Furthermore, in process step E), if several formwork panels are used for the temporary formwork and the closing formwork, formwork locks can be attached to connect these several formwork panels to one another. This preparation of the formwork takes place from the scaffolding section of the system, from which the formwork can be easily reached over its entire height.Since the scaffold section was already connected to the formwork panel before rotation, the previously required effort to erect a scaffold or work platform to prepare the formwork is no longer necessary.

[0038] In a sixth process step (F), a liquid material is poured into the formwork. This material, preferably a concrete material, then encloses the reinforcement and, together with it, forms the wall element. This filling of the formwork can also be carried out and monitored from the scaffolding section.

[0039] In a seventh process step (G), the liquid material poured into the formwork is given time to harden. After the material has hardened, the wall element formed from this material and the reinforcement is self-supporting.

[0040] In an eighth process step H), the temporary formwork and the system that forms the closing formwork are removed. Either the system or the temporary formwork can be removed first; both alternatives are possible. Preferably, after removal of the formwork, the system is rotated again by 180° around a vertical axis until the scaffold section is once again parallel to the produced wall element. In this way, the scaffold section can then be used for further processing of the produced wall element, for example, to fill the holes created in the formwork by the anchors inserted. Rotating the system in this way is significantly less complex than erecting another or additional scaffold for post-processing of the produced wall element. Furthermore, it is possible to position the system on the side on which the temporary formwork was previously arranged.On this opposite side of the wall element, the system is then aligned so that the scaffolding section points toward the wall element. This allows the side where the formwork was previously attached to be reworked from the scaffolding section of the system. The rotation and positioning of the system after the formwork has been removed is again preferably carried out using a crane.

[0041] The method according to the invention has the advantage that the scaffolding section of the system can be used for multiple process steps and for multiple activities during the production of a wall element. This eliminates the effort required for maintaining, assembling, and disassembling different scaffolds or scaffolding systems. In particular, the attachment of the reinforcement and the subsequent preparation of the formwork for filling the material can be carried out very quickly one after the other by simply rotating the system 180°. Furthermore, at the end of the method according to the invention, a connection still exists between the formwork panel and the scaffolding section, making the system inherently stable and load-bearing.It is therefore easy to relocate the system a little further in space to create another wall section or wall element of the building and to use it again directly without having to carry out the assembly and disassembly steps.

[0042] The method according to the invention thus significantly simplifies and accelerates the production of a wall element.

[0043] In one embodiment of the method, in method step B) the system is erected on the ground as in the application, or the system is laid on the ground for assembly. There are several options for erecting the system in method step B). Firstly, the system can be erected from the bottom up, starting from the ground or ground, which corresponds to the assembly sequence usually used for a scaffolding section. Alternatively, the system and / or the scaffolding section can be erected lying on the ground at a different location, even away from the position where the wall element is to be created. This has the advantage that there is no risk of falling for people working on the scaffolding during assembly, and therefore fewer safety precautions need to be taken.Furthermore, the system can be erected at a location on the construction site that is less frequented than the site where the structure is being built. This streamlines logistics and facilitates work on the site. The scaffolding section, which is assembled horizontally, can also be connected to the formwork panel horizontally, and the system can then be positioned, for example, by a crane, at the location where the wall element is to be constructed.

[0044] In a further embodiment of the method, in method step B) the system is anchored in the ground or a support is attached to the system, which points from the formwork panel to the side opposite the scaffolding section. In this embodiment of the method, the system is additionally fastened to the subsurface or to the ground. This may be necessary in cases where the system, and in particular the formwork panel, is very high or where increased loads act on the system, such as high wind loads or a large number of people working on the scaffolding section. Such additional fastening can be achieved, for example, by anchoring the system in the ground or subsurface. The anchoring can be effected between the scaffolding section and the subsurface and / or between the formwork panel of the system and the subsurface. Alternatively, it is possible to attach a known support to the system.Such a support points away from the temporary formwork and away from the scaffolding section of the system in process step B). In this way, the support does not hinder access to the scaffolding section and the attachment of the reinforcement in process step C). Optionally, it is also possible in process step D) to provide additional fastening of the system after rotation and positioning of the system. This can again be achieved by anchoring it in the substructure or by providing a support. However, in process step D), a support is preferably attached to the side of the system on which the scaffolding section is located, so as not to hinder the production of the wall element between the temporary formwork and the closing formwork.

[0045] Features, effects, and advantages disclosed in connection with the system are also deemed to be disclosed in connection with the methods. The same applies in reverse: features, effects, and advantages disclosed in connection with the methods are also deemed to be disclosed in connection with the system.

[0048] Fig. 1 shows a perspective view of an embodiment of a system 100. In Fig. 1 A section of an embodiment of a system 100 is shown schematically. The system 100 comprises a scaffolding section 3, which is shown at the front right. The scaffolding section 3 extends three-dimensionally in three spatial directions and comprises a plurality of vertically oriented vertical posts 51. The scaffolding section 3 further comprises a plurality of horizontally oriented horizontal bars 52. The vertical posts 51 and the horizontal bars 52 are connected to one another via interfaces. The scaffolding section 3 has a modular design, meaning that different shapes and sizes of scaffolding sections 3 can be assembled from standard components such as the vertical posts 51 and the horizontal bars 52 according to the modular principle. The scaffolding section 3 shown here comprises three tread levels, which are arranged one above the other and can be accessed by working persons. The system 100 further comprises at least one formwork panel 2.In the illustrated embodiment, a plurality of formwork panels 2 are provided which are connected to one another at their edges and together form a formwork. The formwork panels 2 are connected to one another via formwork locks. In the illustrated embodiment, a support M is attached to the front of the formwork panel 2, which supports the formwork panel 2 and the system 100 and holds them in position. However, this support M is optional here; the system 100 is also load-bearing without this support M, with the scaffolding section 3 supporting and positioning the formwork panel. This means that the system can also be used free-standing, in particular without the support M. Each formwork panel 2 comprises a frame 21, which forms the load-bearing and load-bearing element of the formwork panel 2. A formwork skin 22 is detachably attached to the frame 21, pointing to the rear left in the illustration.This detachable arrangement of the formwork skin 22 enables easy replacement of the formwork skin 22, for example when it is worn. The frame 21 comprises a plurality of cross struts 212, which are oriented horizontally in the illustration, and a plurality of longitudinal struts 211, which are oriented vertically in the illustration. The longitudinal struts 211 and the cross struts 212 are oriented essentially perpendicular to one another. The formwork skin 22 rests at least partially on the longitudinal struts 211 and the cross struts 212. Undercuts 213 are arranged on the cross struts 212, running in their longitudinal direction, which grooves thereby form grooves with a rectangular cross-section. Details of a cross strut 212 with an undercut 213 are shown in . Fig. 3 The undercuts 213 are intended to be connected to a connecting component 1 in a form-fitting and force-fitting manner. It is also possible for one or more undercuts 213 to be arranged on one or more longitudinal struts 211 for fastening a connecting component 1. Furthermore, it is possible to arrange further struts in the frame 21, which are oriented at different angles to one another and which may also have one or more undercuts 213. Fig. 1 Three connecting components 1 can also be seen, which also belong to the system 100. These connecting components 1 connect the formwork panel 2 to the scaffolding section 3. In the illustrated embodiment, each connecting component 1 has two formwork interfaces 12, which are connected to the frame 21 of the formwork panel 2. Details of a connecting component 1 and its interfaces are shown in Fig. 2 Each formwork interface 12 comprises a clamping element 121, which in turn comprises two gripping arms 1211. The gripping arms 1211 engage in an undercut 213 in some areas and thus form a positive connection between the formwork interface 12 and the frame 21, in particular a cross strut 212, of the formwork panel 2. One of the two gripping arms 1211 is designed to be movable relative to another gripping arm 1211. The distance between the two gripping arms 1211 is thus adjustable, whereby the clamping element 121 can be brought into engagement with one or more undercuts 213. Each connecting component 1 further comprises a support element 13, to which the formwork interface 12 is fastened. The support element 13 is rod-shaped and is formed here by a tube with a round cross-section. The support element 13 has a longitudinal axis, which extends in the vertical direction in the illustration.The longitudinal axis of the support element 13 is arranged essentially parallel to the surface of the formwork facing 22. In the illustrated embodiment, the support element 13 is designed very similarly to a vertical post 51 of the scaffolding section 3. In the illustrated embodiment, the connecting component 1, in functional combination, simultaneously forms a vertical post 51 of the scaffolding section 3. Furthermore, in the illustrated embodiment, a plurality of scaffolding interfaces 11 are arranged on the support element 13, which are arranged here at regular intervals along the longitudinal axis of the support element 13. The scaffolding interfaces 11 of the illustrated embodiment correspond to interfaces that are also arranged on the vertical post 51 of the scaffolding section 3. Thus, the scaffolding interfaces 11 can be connected to other components or elements of the scaffolding section 3 in the same way as the interfaces arranged on a conventional vertical post 51.As a result, the connecting component 1 is fully integrated into the scaffolding section and can be modularly combined with other components of the scaffolding section 3. The scaffolding interfaces 11 are designed as connecting discs or rosettes. Both the connection between the scaffolding interface 11 and the scaffolding section 3 and the connection between the formwork interface 12 and the formwork panel 2 are designed to be just as load-bearing as connections within the scaffolding section 3. This enables force transmission between the formwork panel 2 and the scaffolding section 3 through the connecting component 1. In this way, the system 100 can be used freestanding, since the formwork panel 2 and the scaffolding section 3 support each other and hold each other in position. Furthermore, it is possible to transport the system using a crane; it is sufficient to connect the crane either to the formwork panel 2 or to the scaffolding section 3.The other component of the system 100 is held to the crane by the connections through the connecting component 1. In . Fig. 1 It is clearly visible that the selected embodiment of a connecting component 1, which in functional combination forms a vertical post 51, makes it possible to save additional vertical posts 51 in the scaffolding section 3. The system 100 according to the invention thus reduces the weight of a connection between the formwork panel 2 and the scaffolding section 3. Furthermore, components for the scaffolding section 3 are saved compared to the prior art. In the embodiment shown, it is provided that when the system is assembled or during production of the wall element, the formwork panel 2 and the scaffolding section 3 remain connected to one another by the connecting component 1. However, the connections to the connecting component 1 are easily detachable, so that the formwork panel 2 and the scaffolding section 3 can also be easily separated, for example when dismantling the system.

[0049] Fig. 2 shows a side view of a connecting component 1 in functional combination with a vertical post 51. In Fig. 2 a connecting component 1 according to the embodiment can be seen, which is also shown in Fig. 1 The connecting component comprises a support element 13, the longitudinal axis of which is oriented vertically in the illustration. Two formwork interfaces 12 are arranged on the support element 13, pointing to the left and spaced from one another. Opposite the formwork interfaces 12, a total of eight scaffolding interfaces 11 are arranged on the support element 13, also spaced from one another. Six of these scaffolding interfaces 11 are designed as connecting discs or rosettes, which extend from the support element 13 to the right. These connecting discs or rosettes are identical to, or at least very similar to, interfaces that are also arranged on a vertical post 51 of the scaffolding section 3. Thus, a connection of components of the scaffolding section 3 to the scaffolding interfaces is possible in the same way as with a connection of components within the modularly constructed scaffolding section 3.The upward-facing end and a recess in the downward-facing end of the support element 13 are also scaffolding interfaces 11. These two scaffolding interfaces 11 can be used to establish a connection to vertical posts 51 of the scaffolding section 3 at the ends of the support element 13 by inserting them. The scaffolding interfaces 11 are arranged on the support element 13 at distances from one another which correspond to the grid of connection interfaces in the scaffolding section 3. Thus, the connecting component 1 in the illustrated embodiment can be fully integrated into the scaffolding section 3. Each formwork interface 12 has a clamping element 121, which in turn comprises two gripping arms 1211. The lower of the gripping arms 1211 is designed to be immovable relative to the support element 13, whereas the upper of the two gripping arms 1211 is designed to be movable relative to the lower gripping arm 1211.The clamping element 121 further comprises an unlocking mechanism 1220, which is operated via a lever. The distance between the two gripping arms 1211 can be changed by the unlocking mechanism 1220. To connect the connecting component 1 to the formwork panel 2, the unlocking mechanism 1220 is first actuated such that the distance between the two gripping arms 1211 is greater than the width of a cross strut 212 of the frame 21. In this state, the two gripping arms 1211 are partially pushed over the cross struts 212. The unlocking mechanism 1220 is then actuated so that the distance between the two gripping arms 1211 is reduced. In this process, a projection 1211a, which is arranged at the left-facing tip of the gripping arm 1211, penetrates into an undercut 213 on the cross strut 212. Details of this connection are in . Fig. 3 can be seen. By further actuating the unlocking mechanism 1220, the cross strut 212 is then clamped between the gripping arms 1211. In this state, a positive connection and a frictional connection then exist between the formwork interface 12 and the frame 21. In the illustrated embodiment, each clamping element 121 has an unlocking mechanism 1220, which is operated individually. However, it is also possible to couple the unlocking mechanisms 1220 of both formwork interfaces 12 to one another, for example by connecting them with a cable or a rod. In this coupled embodiment, both unlocking mechanisms 1220 can then be operated simultaneously. This accelerates the connection and separation between the connecting component 1 and the formwork panels 2.The distance between the two formwork interfaces 12 in a direction parallel to the longitudinal axis of the supporting element 13 corresponds to an integer multiple of the distance between two cross struts 212 of the formwork panel 2. Fig. 1 This ensures compatibility between the grid of the connecting component 1 and the grid of the formwork panel 2. Due to this compatibility of the grids, the connecting component 1 can be flexibly and securely fastened to different positions on the formwork panel 2 without the need for additional components to compensate for any grid differences. Alternatively, the position of a formwork interface 12 on the support element 13 can be adjustable in order to compensate for tolerances. In addition, a compensation element 14 can be provided, which allows the formwork interface 12 to be displaced relative to the support element 13 in its longitudinal direction. However, such a compensation element 14 is optional and therefore not included in Fig. 2 A compensating element 14 can also be arranged between the support element 13 and one or more scaffold interfaces 11.

[0050] Fig. 3 shows a sectional view through a cross brace 212 of a formwork panel 2, which belongs to an embodiment of the system. In Fig. 3 the cross braces 212 can be seen, which are Fig. 2 is connected to the formwork interface 12 of the connecting component 1. The cross strut 212 is shown in section in a plane perpendicular to its longitudinal direction. In the illustration, to the left of the cross strut 212, also shown in section, the formwork skin 22 can be seen, which is connected to the frame 21. The formwork skin 22 lies flat on the left-facing side of the cross struts 212. In the background, a longitudinal strut 211 can be seen in some areas, which is connected to the sectioned cross strut 212. The illustration also shows the two gripping arms 1211 of the clamping element 121, which are connected to the cross strut 212 in a force-fitting and form-fitting manner. The cross strut 212 is formed by a profile tube which has the shape of a bone.On the side of the cross strut 212 pointing upwards in the illustration and on the side pointing downwards in the illustration, an undercut 213 can be seen, which here is designed as a groove extending in the longitudinal direction of the cross strut 212, i.e., in the illustration, into the plane of the drawing. The grooves forming the two undercuts in 213 have an identical, rectangular cross-section. The two undercuts 213 are vertically symmetrical and arranged opposite one another on the cross strut 212. The areas of the gripping arms 1211, which in . Fig. 3 are illustrated are of identical design. Both gripping arms 1211 have a projection 1211a at their tip, which is directed to the left in the illustration, which projection here forms an area that engages in one of the undercuts 213. In the embodiment shown, the lower of the two gripping arms 1211 is designed to be movable in a direction parallel to the formwork skin 22, whereby the distance between the two gripping arms 1211 is adjustable. 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 symbolized by an arrow in the illustration, so that the distance between the two projections 1211a is greater than the width of the cross struts 212 in the vertical direction.The two gripping arms 1211 are then partially pushed over the cross struts 212 until the projections 1211a are adjacent to the two undercuts 213. The lower gripping arm 1211 is then moved toward the upper gripping arm 1211, and the distance between the two gripping arms 1211 is reduced. In doing so, the two projections 1211a each engage in an undercut 213, creating a positive fit. In this state, in which the two projections 1211a already form a positive fit with the undercuts 213, the clamping element 121 can be moved parallel to the direction of the undercuts 213 along the cross struts 212 until the desired relative position between the clamping element 121 and the cross strut 212 is reached. The lower gripper arm 1211 is then moved towards the upper gripper arm 1211 until the two gripper arms 1211 clamp the cross struts 212.In this state, a force flow also exists between clamping element 121 and cross braces 212. The described adjustability of the relative position of clamping element 121 along undercut 213 is particularly advantageous for a flexible connection between connecting component 1 and 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 illustrated longitudinal brace 211, which is aligned with the undercuts 213 of the cross brace 212.

[0051] Fig. 4 shows a perspective detailed view of an embodiment of a formwork interface 12 of a connecting component 1. The connecting component 1 in the Fig. 4 The embodiment shown does not comprise a support element 13. In the embodiment shown, the clamping element 121 of the formwork interface 12 comprises an intermediate post 122, which is formed by a tubular section with a round cross-section. The size and shape of the cross-section of the tubular section of the intermediate post 122 corresponds to the shape and size of a vertical post 51 of the scaffolding section 3. The two gripping arms 1211 and the unlocking mechanism 1220 are arranged on the intermediate post 122 and connected to a cross strut 212 of the formwork panel 2. A scaffolding interface 11 is arranged on the intermediate post 122. The relative position of the scaffolding interface 11 and the intermediate post 122 is adjustable here, with at least three possible positions of the scaffolding interface 11 being provided on the intermediate post 122. These three positions can be adjusted by moving the scaffolding interface 11 on the intermediate post 122 along its longitudinal direction.In the embodiment shown, both the scaffolding interfaces 11 and the intermediate post 122 have bores into which a plug-in element can be inserted to establish the position of the components relative to one another. Thus, in the embodiment shown, the position of the scaffolding interface 11 relative to the clamping element 121 is adjustable. This means that the connecting component 1 can be easily adapted to different applications. The scaffolding interface 11 is identical in shape and size to an interface which is also used within the scaffolding section 3, in particular on a vertical post 51. Thus, elements of the scaffolding section 3, such as a . Fig. 4 shown horizontal bar 52, in the same way as a connection of different scaffolding elements within the scaffolding section 3 takes place. Also in the Fig. 4 In the embodiment shown, the clamping element 121 comprises an unlocking mechanism 1220, by means of which the connection between the gripping arms 1211 and the cross strut 212 can be easily and quickly established and released again.

[0052] Fig. 5 shows a perspective detailed view of another embodiment of a formwork interface 12 of a connecting component 1. 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 strut 212 of the formwork panel 2. In Fig. 5 this pin element 1212 is hidden and therefore not shown. A corresponding recess, which is suitable for receiving the pin element 1212, is shown on the right-hand side adjacent to the clamping element. The recess here forms an undercut 213. The second gripping arm 1211 is formed in the illustrated embodiment by a clamping element 1213. This clamping element 1213 partially encompasses the cross strut 212 and rests against it. The clamping element 121 further comprises a clamping mechanism, which here contains a threaded spindle and a handwheel. By means of this clamping mechanism, the relative position between the pin element 1212 and the clamping element 1213 can be changed. When the clamping element 121 is attached to the cross strut 212, the pin element 1212 is inserted into the recess and the clamping mechanism is then actuated.As a result, the pin element 1212 and the tensioning mechanism 1213 are moved towards each other, creating a positive and non-positive connection between the clamping element 121 and the cross brace 212. A support element 13 is arranged on the clamping element 121 and the scaffolding interface 12. This support element 13 connects the formwork interface 12 to a scaffolding interface 11. The scaffolding interface 11 is designed here as a connecting clamp 1214, which is connected to a vertical post 51 of the scaffolding section 3. The connecting clamp 1214 engages around the vertical post 51 and is fastened to it in a non-positive manner using a screw connection. The advantage of this embodiment is that the scaffolding interface 11, designed as a connecting clamp 1214, can be continuously moved along the vertical post 51 and then positioned in a non-positive manner. This allows the relative position of the connecting component 1 to the scaffolding section 3 to be adjusted very flexibly.It is also possible to arrange several scaffolding interfaces 11 on the supporting element 13 if required.

[0053] Fig. 6 shows a perspective detailed view of another embodiment of a formwork interface 12 of a connecting component 1. In this embodiment of a connecting component 1, the relative position of the formwork interface 12 to the scaffolding interface 11 is adjustable. For this purpose, the formwork interface 12 is designed as a compensating rail 1215. This compensating rail 1215 comprises a first partial area, which forms a gripping arm 1211, which is inserted into the undercut 213 in the cross strut 212. This first partial area is formed by two flat irons arranged at an angle to one another, which are connected by a bolt that is oriented vertically in the illustration. This bolt is inserted into a cylindrical recess in the cross strut 212, which forms an undercut 213.The second gripping arm 1211 is not visible in the illustration and is formed by a locking pin which is inserted into the vertically oriented bolt on the side which, in the illustration, is located below the cross strut 212. The compensating rail 1215 further comprises a second partial region which, in the illustration, faces to the front right. This second partial region is formed by a rail with a constant cross-section, which in this case has a rectangular cross-section. In this embodiment, the scaffolding interface 11 is formed by a clamp 1216 which is adjustably connected to the compensating rail 1215. For this purpose, the clamp 1216 has a connection region which, in some regions, is designed to be complementary in shape to the rail with a constant cross-section of the compensating rail 1215.The connection area encompasses the rail with a constant cross-section and is movable along the longitudinal axis of the rail with a constant cross-section. The clamp 1216 further comprises a locking element which can be inserted into the connection area and which, in the state shown, clamps the clamp 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 scaffolding interface 11 and the formwork interface 12, the connection area is first moved relative to the compensation rail 1215 until the desired position of the formwork interface 12 and the scaffolding interfaces 11 is reached. The locking element is then inserted and this relative position is fixed. The clamp 1216 further comprises a connecting clamp 1214 which is firmly connected to the connection area.The connecting clamp 1214 is as shown in . Fig. 5 illustrated embodiment is non-positively connected to a vertical post 51 of the scaffolding section 3. The illustrated embodiment of a connecting component 1 is particularly advantageous because, on the one hand, the relative position between the formwork interface 12 and the scaffolding interface 11 is adjustable and, on the other hand, the connecting clamp 1214 of the scaffolding interface 11 is continuously adjustable in its position relative to a vertical post 51. Thus, this embodiment of a connecting component 1 enables adjustment of the position between the formwork panel 2 and the scaffolding section 3 in two spatial directions oriented perpendicular to one another.

[0054] The Fig. 4 bis Fig. 6 The embodiments of a connecting component 1 shown can all 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 alternatively and / or additionally in a system 100 according to the Fig. 1 und 2 The embodiments shown in the Fig. 1, 2 , 4 , 5 und 6 The embodiments shown can thus be used in any combination in a system 100, which allows 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.

[0055] Fig. 7 shows a perspective view of a first state when carrying out a method according to the invention. In Fig. 7 bis 9 sequentially occurring states are shown which occur in a method for producing a wall element using a system 100. In Fig. 7 According to process step A), a formwork assembly has already been erected, which is located at the back left in the illustration. The formwork assembly corresponds to the state of the art and is constructed from several formwork panels 2 which are connected to one another. The formwork assembly is held in its vertically oriented position by at least one support M. Opposite the formwork facing of the formwork assembly, a system parallel to the formwork assembly was constructed according to process step B). The system 100 here comprises a total of twelve formwork panels 2 which are joined together to form a common formwork. The formwork panels 2 are connected to a scaffolding section 3 via several connecting components 1 which are hidden in the illustration. The scaffolding section 3 points towards the formwork assembly and is oriented parallel to its formwork facing. There is a distance between the formwork assembly and the scaffolding section 3 which roughly corresponds to the thickness of the wall element to be produced.In the one in . Fig. 7 In the state shown, reinforcement B has already been attached to the formwork. The reinforcement B is formed by several iron mats. The reinforcement B was attached and secured by people working from scaffold section 3. Scaffold section 3, with its three treads arranged one above the other, is designed so that the entire surface of the formwork can be easily reached by working people. Thus, reinforcement can be attached quickly and easily from scaffold section 3. In the Fig. 7 In the state shown, the reinforcement B is already completely attached to the formwork and the workers have left the scaffold section 3. In the next step, the system 100 will be rotated around a vertically oriented, fictitious axis VA in order to Fig. 7 The formwork skin 22 of the formwork panels 2 of the system 100, facing forward to the right, is to be oriented toward the formwork and the reinforcement B. For this rotation, the entire system can be lifted by a crane and rotated while suspended from the crane. The rotation of the system 100 occurs according to the arrow P shown to the right of the system 100.

[0056] Fig. 8 shows a perspective view of a second state when carrying out a method according to the invention. In Fig. 8 a state is shown which occurs during the rotation of the system 100 according to method step D). Starting from the Fig. 7 In the state shown, the system 100 has already been rotated around the fictitious, vertically oriented axis VA by an angle of approximately 120°. The scaffold section 3, which is Fig. 7 nor to the formwork, indicates in the Fig. 8 The state shown is already away from the formwork. Starting from the Fig. 8 In the state shown, the rotation of the system around the axis VA in the direction of the arrow P is continued until the formwork panels 2 of the system 100 are aligned parallel to the temporary formwork and the formwork skin 22 of the scaffolding system 100 points towards the reinforcement B and the temporary formwork. Overall, the system 100 is rotated by 180°. This rotation according to process step D) enables a very rapid erection of a closing formwork, which is formed by the same system 100 that previously served with its scaffolding section 3 to fasten the reinforcement B. The system is simply rotated by 180° using a crane and set up parallel to the temporary formwork. The formwork is thus already fully erected and the temporary formwork and the system together delimit the spatial area in which the wall element is to be manufactured. A further advantage is that after the 180° rotation, the scaffolding section 3 is still connected to the formwork panels 2 of the system 100.After rotating, preparation of the formwork for the pouring of liquid concrete material according to process step E) can begin directly from scaffold section 3. During this preparation of the formwork, anchors could, for example, be placed between the system and the temporary formwork. These anchors connect the two parts of the formwork and hold the two parts of the formwork together and absorb forces when the concrete material is poured. The work to prepare the formwork can again be carried out by people who are on scaffold section 3 and can easily reach every point on the formwork from there. By rotating according to process step D), there is no longer any need to dismantle a reinforcement scaffold, which according to the state of the art must be used to attach the reinforcement to the temporary formwork.In addition, the erection of a scaffold or a working platform to prepare the formwork after the erection of the system 100 as closing formwork is eliminated, since the scaffold section 3 is already in connection with the formwork panels 2.

[0057] Fig. 9 shows a perspective view of a third state when carrying out a method according to the invention. Before the Fig. 9 In the state shown, after the formwork had been prepared according to process step E), liquid material, in particular concrete material, was filled into the formwork according to process step F). In the process, the reinforcement B was enclosed in the concrete material. The formwork can also be filled by persons located on scaffold section 3. Furthermore, the filling of the formwork can be conveniently monitored from scaffold section 3. Furthermore, before the Fig. 9 In the state shown, the filled material in the formwork has hardened according to process step G), whereby the wall element W has been created, which consists of the hardened concrete material and the reinforcement B. The hardening of the concrete material can also be monitored from the scaffold section 3. In the Fig. 9 In the state shown, the formwork and the system 100 are removed from the manufactured wall element W. In the illustration, the formwork and the system 100 are shown parallel and offset from the wall element W. However, the formwork and the system can also be lifted out using a crane. After the manufacture of this wall element W, the system can be used directly to attach another reinforcement B to another formwork without any further modifications, analogous to the Fig. 7The system can be used in the state shown. For example, the system 100 can simply be rotated back around the fictitious vertically oriented axis VA by crane and positioned elsewhere on the construction site. The system can thus be used again without interruption to produce another wall element. This simplifies the production of a wall element, as significantly less effort is required for the assembly and dismantling of formwork and scaffolding. This also reduces the time required to produce a wall element W. List of reference symbols:
