Connecting component and system for the formwork of a wall element

Description

[0001] The present application claims priority from German patent application No. 10 2021 120 438.0 and priority from German patent application No. 10 2021 120 441.0.

[0002] The invention relates to a connecting component having a formwork interface for detachable connection with a frame of a formwork panel.

[0003] The invention also relates to a system for the formwork of a wall element, comprising at least one formwork panel and at least one connecting component.

[0004] 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 happen, the formwork panels must be accessible to workers along their entire height, which is usually achieved using scaffolding or a work platform.

[0005] In most cases, reinforcement must be installed on a pre-positioned formwork panel or between such a formwork panel and a closing formwork panel opposite the formwork panel before the wall element is manufactured. According to current technology, scaffolding or work platforms intended for installing formwork locks 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 formwork panel. In practice, this means that one type of scaffolding is required for operating the formwork, and a second type of scaffolding is required for positioning and installing the reinforcement within 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 needed again after the actual casting process to carry out these final tasks. In addition, it is also necessary to equip the formwork panels with guide supports.The production of a wall element using formwork therefore requires a large number of different scaffolds or work platforms, which leads to complicated work processes and a need for a large number of different scaffold elements.

[0006] Connecting elements with a formwork interface and an attachment interface are known in the prior art, for example, through KR101339284B1 or US5575938A.

[0007] The present invention is therefore based on the objective of simplifying the manufacture of a wall element, in particular enabling flexible, universal and / or secure fastening of scaffolding, stages and / or supports to formwork panels.

[0008] The problem is solved according to the invention by claim 1.

[0009] According to the invention, a connecting component is proposed, comprising a formwork interface for detachable connection with a frame of a formwork panel, wherein the formwork interface comprises a first gripping device having at least one first gripping arm with a clamping jaw and a second gripping device having at least one second gripping arm with a clamping jaw, wherein the first gripping arms of the first gripping device are movable relative to the second gripping arms of the second gripping device in a closing direction in order to connect or disconnect the clamping jaws with the frame and comprising at least one attachment interface for detachable connection with an attachment, wherein the formwork interface and the attachment interface can be operated independently of each other.

[0010] The connecting component according to the invention creates a combination between a formwork interface and an attachment interface, with which a large number of different objects, in particular different types of scaffolding, platforms, supports, etc., can be detachably connected to the frame of the switchboard in an advantageous manner.

[0011] The attachment interface can be connected to a scaffold section, in particular a vertical standard of a scaffold, a platform section, or a support, in particular a guide support, as an attachment. In particular, several attachment interfaces can also be provided, in particular one attachment interface for a scaffold section and a separately designed attachment interface for a support, in particular a guide support.

[0012] The attachment interface preferably includes a connecting clamp for receiving an attachment. The connecting clamp can preferably be positively connected to, for example, a vertical post of a scaffold section, or be connectable to it.

[0013] The formwork panel to which the connecting component can be detachably fixed may preferably have a frame to the front of which a formwork skin can be fixed, in particular attached or affixed. The frame of the formwork panel further preferably has several longitudinal struts and several transverse struts running parallel to each other. The longitudinal struts and the transverse struts may be arranged substantially perpendicular to each other or may run perpendicular to each other.

[0014] In an advantageous embodiment of the frame, particularly suitable for the system defined in claim 12, at least one arched bridging element can be arranged between at least two adjacent crossbeams. The bridging element can have two end regions, each end region being fixed to one of the two adjacent crossbeams. The arched bridging element can ergonomically simplify the handling of the formwork panel. The formwork panel can be transported and positioned more easily with the aid of the arched bridging element. Provided this is legally permissible in the respective jurisdictions, the bridging element can also advantageously serve as a handle and / or as a climbing aid or as a climbing rung, particularly in conjunction with scaffolding positioned adjacent to or on the formwork panel.The arched bridging element can, in particular, be an arched handle. The arched design of the bridging element makes it especially advantageous for a worker to grip it.

[0015] The formwork interface can have a locking mechanism to adjust and / or releasably fix the position of the gripping arms in the closing direction.

[0016] The locking mechanism allows the clamping jaws of the first and second gripping arms to be connected to the frame, in particular to the crossbars and / or longitudinal bars of the frame, e.g. clamped.

[0017] The locking mechanism can include a wedge, the outer contour of which preferably forms at least a partial control surface.

[0018] This measure provides a simple, reversible and at the same time secure locking option.

[0019] The two gripping devices can each have recesses which at least partially overlap each other and into which the wedge can be inserted or is inserted.

[0020] It is advantageous if the connecting component is designed such that a movement of the wedge relative to the recesses results in a closing movement (in the closing direction), during which the gripping arms move towards each other. Preferably, one of the gripping devices, preferably the first gripping device, does not move relative to the frame, but rather the closing movement of the gripping devices results solely from the movement of one of the two gripping devices, preferably the second gripping device, which thus also moves relative to the frame, e.g., orthogonally to a cross member of the frame to which the connecting component is to be attached.

[0021] The wedge can be arranged in the recesses in a way that prevents it from being lost, preferably with stops projecting beyond the recesses at its end faces to form the loss prevention mechanism.

[0022] The locking device can be designed, for example, in the form of a tension pin, a tension sleeve, a cotter pin, a locking pin, a bolt, or the like.

[0023] The control surface of the wedge can preferably be designed such that, by moving the wedge into a locking position, the gripping arms of the first gripping device and the second gripping device move relative to each other in the closing direction and thus engage the frame, in particular the cross members and / or longitudinal members of the frame, or engage the frame or are clamped to the frame.

[0024] The control surface of the wedge or the locking mechanism is particularly suitable if, as will be explained in more detail below, the frame, in particular the crossbars and / or longitudinal bars of the frame, have grooves and the clamping jaws of the gripping arms engage in the grooves.

[0025] Preferably, the wedge can be moved into its locking position using a hammer or a similar, suitable tool.

[0026] The first gripping device may preferably have two first gripping arms and the second gripping device may have a second gripping arm.

[0027] This allows the connecting component to be stable and fixed to the frame.

[0028] The gripping arms can run parallel to each other and spaced apart, and the second gripping arm can be arranged in a gap, preferably in the middle, between the two first gripping arms.

[0029] At least one bolt may be present, which bridges a gap between the first gripping arms and is arranged in such a way that it serves as a stop for a movement of the second gripping arm in the opposite direction to the closing movement.

[0030] The bolt can also be used to connect the first two gripping arms.

[0031] It is advantageous if the clamping jaws have a projection at their front ends that is designed to engage in grooves of the frame.

[0032] It is advantageous if at least some of the crossbars and / or longitudinal bars have at least one groove on the top and bottom surfaces that runs in the longitudinal direction of the crossbars.

[0033] Within the scope of the invention, the "top" and the "bottom" of the transverse struts (or longitudinal struts) are also collectively referred to as side surfaces.

[0034] In cross-section, the profile of the transverse and / or longitudinal struts can preferably have the shape of a bone or an "H". Using the grooves and the connecting component according to the invention, various scaffolds, platforms, and / or supports, especially alignment supports, can be attached to the formwork panel particularly easily and securely. The connecting component, whose gripping devices or gripping arms are preferably adapted to the profile, can be variably attached to and removed from the frame. This allows for particularly flexible attachment of scaffolds, platforms, and / or supports, especially alignment supports for aligning the formwork.

[0035] It has proven particularly suitable if the grooves extend over the entire length of the respective cross member and / or longitudinal member. This allows the connecting components to be attached to the frame in a particularly advantageous and flexible manner.

[0036] The grooves can be arranged axially symmetrically to each other in the cross-section of the respective longitudinal strut and / or transverse strut and / or be arranged opposite each other and have at least approximately the same shape in cross-section.

[0037] By engaging the clamping jaws in the grooves, a stable force-fit and form-fit connection can be created between the connecting component and the longitudinal struts and / or transverse struts of the frame of the formwork panel.

[0038] Preferably, the clamping jaws are designed to be form-complementary to the grooves in the longitudinal and transverse struts of the formwork panel.

[0039] The relative position between the connecting component and the formwork panel can be continuously adjustable in a direction parallel to the direction of the grooves in the longitudinal struts and / or transverse struts.

[0040] The connecting component is particularly advantageous because it can be attached to the frame at a suitable horizontal (or vertical) position, especially along the frame's cross members, using the grooves. Additionally, the position between the formwork interface and the attachment interface can also be adjustable.

[0041] Secondly, a connecting element formed at the attachment interface, e.g., a connecting clamp of the attachment interface, can be designed to be continuously adjustable in its position relative to a scaffold section, e.g., a vertical standard. Thus, the connecting element allows for adjustment of the position between the formwork panel and the scaffold section or a guide support in two mutually perpendicular spatial directions.

[0042] The grooves allow the connecting component to be securely attached to the longitudinal and / or transverse struts of the formwork panel frame.

[0043] It is advantageous if the grooves in the top and bottom surfaces of the respective crossbars and / or longitudinal bars run off-center, such that the grooves are closer to the back of the frame than to the front.

[0044] Preferably, the grooves in the top and bottom surfaces run at a constant or uniform distance to the edges of the top or bottom surfaces of the cross member or longitudinal member.

[0045] Preferably, the grooves run off-center on the top or bottom of the cross braces and / or longitudinal braces such that they are located further away from the front edge of the brace, where the top or bottom abuts the front of the frame or the formwork skin, than from the respective rear edge of the brace, which abuts the back of the frame. Because the grooves run off-center in this way, the connecting component can be particularly advantageously fixed or clamped in the grooves.

[0046] It is also advantageous if the crossbars have holes spaced apart from the grooves on the top and / or bottom, which preferably serve to drain liquids, for example rainwater.

[0047] It has proven advantageous if the side walls or the flanks of the respective grooves are inclined outwards from the base of the respective grooves, wherein the side walls can preferably form an angle of 95° to 125°, in particular 110°, with the base of the groove.

[0048] The grooves can preferably have a depth of 9 mm to 16 mm, preferably 13 mm.

[0049] The aforementioned values ​​have proven particularly suitable for defining the connecting component. This geometry allows the connecting components to be fixed in the grooves particularly easily and securely, preferably using clamps.

[0050] The optional design of one or more bridging elements has proven particularly advantageous in conjunction with cross members that have at least one groove on their upper and lower surfaces, extending longitudinally along the cross members, especially as described above. Particularly with a particularly advantageous design of the cross members featuring grooves that run off-center such that the grooves are a greater distance from a leading edge of the cross member, the arc-shaped profile of the bridging element is especially suitable. The arc-shaped profile of the bridging element makes it possible to fix the bridging element in a section of the upper or lower surface of the cross members that does not have a groove. These sections border the front of the frame.A linear bridging element would have the disadvantage that, due to its proximity to the front of the frame and thus also to the formwork skin, it would be difficult for a worker's hand to grip it properly or easily. The curved design of the bridging element advantageously solves this problem.

[0051] It can be advantageous if the frame has two outer cross members and two outer longitudinal members, between which inner cross members are arranged.

[0052] It is possible for at least one bridging element to be arranged between two of the inner crossbars. This arrangement has proven particularly suitable. Such a positioning is especially advantageous when the bridging element serves as a handrail or climbing aid.

[0053] It can be designed so that all inner cross members have grooves and the outer frame cross members do not. It has proven sufficient if all inner cross members have grooves. Therefore, the additional provision of grooves on the outer frame cross members can be omitted for cost reasons.

[0054] According to the invention, the formwork interface and at least one of the attachment interfaces are detachably connected to each other, wherein the formwork interface and the attachment interface each have a contact surface with an elongated hole, and wherein a fastening element can be inserted through the elongated holes to detachably connect the contact surfaces to each other.

[0055] The fastening element can preferably be designed in the form of a double T. This achieves an advantageous and preferably detachable coupling between the formwork interface and the attachment interface.

[0056] The positive-locking connection between the formwork interface and the attachment interface using the fastening element can preferably be achieved by inserting the fastening element into the elongated holes in an orientation aligned with the elongated holes and then rotating it preferably by 90 degrees, so that a crossbar of a T rests on the inside of the respective elongated hole and thus the fastening element can no longer be removed from the elongated holes.

[0057] Alternatively, a connection between the formwork interface and the attachment interface can also be established by means of a screw connection or other method familiar to the expert.

[0058] The fastening element can be materially bonded to the contact surface of the attachment interface or the formwork interface and / or the second gripping arm can have a projection which is designed and arranged in such a way that rotation of the fastening element is limited by the projection.

[0059] The material-bonded connection of the fastening element to the attachment interface or the formwork interface can preferably be achieved by welding or riveting. Other connection methods are also conceivable.

[0060] Preferably, the fastening element is materially bonded to the attachment interface and positively bonded to the formwork interface, wherein rotation of the fastening element relative to the formwork interface is preferably prevented by the projection of the second gripping arm.

[0061] The contact surface of the formwork interface can be formed by an angled surface of one of the first gripping arms and / or the contact surface of the attachment interface can be formed by a base of a rail with a U-shaped cross-section.

[0062] The contact surface of the formwork interface can preferably be designed by angling one of the first gripping arms at its end furthest from the clamping jaw. Following this angled section, the contact surface of the formwork interface, which serves to connect the attachment interface, can be formed.

[0063] At least one of the attachment interfaces may have a bore for attaching a guide support.

[0064] The bore or the attachment interface for the guide support can preferably be formed in at least one of the first and / or the second gripping arms.

[0065] Instead of being used to attach a guide support, the hole can also be used, for example, to fix tools using a carabiner or similar device.

[0066] The attachment interface for the guide support can alternatively be realized by another fastening option instead of a bore; for example, the attachment interface can be designed as a hook or angle.

[0067] Claim 12 specifies a system for formwork of a wall element, comprising at least one formwork panel and at least one connecting component, wherein the formwork panel has a frame with several longitudinal struts and several transverse struts, wherein the longitudinal struts and the transverse struts are arranged substantially perpendicular to each other, wherein at least a part of the longitudinal struts and / or the transverse struts has at least two grooves which extend longitudinally and on opposite side faces of the respective longitudinal strut and / or transverse strut, and wherein the connecting component is a connecting component according to any one of claims 1 to 11, wherein the gripping arms of the connecting component engage in the at least two grooves of a respective longitudinal strut and / or transverse strut.

[0068] Within the scope of the invention, it may be provided that a cross member is divided into two or more cross member sections by a longitudinal member. Such a multi-section cross member is to be regarded as a single cross member within the scope of the invention. This applies in particular if all cross member sections run parallel to each other and thus, from a functional perspective, form a single cross member.

[0069] In a particularly advantageous embodiment of the formwork panel, it can be provided that it has two longitudinal struts, which form outer frame longitudinal struts, and optionally an inner longitudinal strut running centrally and parallel to the frame longitudinal struts. This inner longitudinal strut can divide each of the transverse struts into two transverse strut parts.

[0071] Functionally identical elements are provided with the same reference symbols in the figures.

[0072] Figure 1Figure 1 shows a formwork panel 1, which, together with connecting components 2, forms a system 3 for the formwork of a wall element (not shown). The formwork panel 1 has a frame 4, which has several transverse braces 5 and several longitudinal braces 6, wherein the longitudinal braces 6 and the transverse braces 5 are arranged substantially perpendicular to each other. At least some of the longitudinal braces 6 and / or the transverse braces 5 have at least two grooves 7, 8, which run longitudinally and on opposite side surfaces 9 (or on the top and bottom) of the respective longitudinal brace 6 and / or transverse brace 5. Figure 1 Only the upper side surfaces 9 of the crossbars 5 with the grooves 7 are visible. Only the crossbars 5 are provided with the grooves 7. The grooves 8 on the lower side surfaces 9 of the crossbars 5 are in Figure 2 more clearly. As in Figure 1As further shown, a scaffold section 10 with vertical posts 10a and horizontal beams 10b is attached to the formwork panel 1 by means of the connecting components 2.

[0073] What's next? Figure 1 As can be seen, the formwork panel 1 has a formwork skin 11 which, when connected to the frame 4, rests on at least a part of the longitudinal struts 6 and / or the transverse struts 5. The side surfaces 9 of the respective longitudinal strut 6 and / or transverse strut 5, in which the grooves 7, 8 are arranged, run essentially perpendicular to a front face of the frame 4 provided for attaching the formwork skin 11.

[0074] The frame 4 comprises two outer frame cross members 5a and two outer frame longitudinal members 6a, between which the inner cross members 5 and / or the inner longitudinal members 6 are arranged, the inner cross members 5 having the grooves 7, 8.

[0075] All inner cross members 5 and / or all inner longitudinal members 6 may have the grooves 7, 8 and the outer frame cross members 5a and / or the outer frame longitudinal members 6a may preferably not have grooves 7, 8.

[0076] In the present embodiment, all inner crossbars 5 include the grooves 7, 8.

[0077] In Figure 2 is a cross brace 5 of a formwork panel 1 (in Figure 2 (not shown) with a connecting component 2, which engages in the grooves 7, 8 of the cross member 5. In a further embodiment, the cross member 5 could also be a longitudinal member 6. The grooves 7, 8 are arranged axially symmetrically to each other and opposite each other in the cross-section of the respective longitudinal member 6 and / or cross member 5.

[0078] The grooves 7, 8 can extend at least over a partial length or over the entire length of the respective longitudinal strut 6 and / or transverse strut 5.

[0079] The connecting component 2 has a formwork interface 200 for detachable connection with the frame 4 of the formwork panel 1. The formwork interface 200 comprises a first gripping device 210 having at least one first gripping arm 211 with a clamping jaw 212 and a second gripping device 220 having at least one second gripping arm 221 with a clamping jaw 222 (see Figure 3 ).

[0080] In the exemplary embodiments (see also the Figures 11 to 18 and the Figures 22 to 25 The first gripping device 210 has two first gripping arms 211, each with a clamping jaw 212. The second gripping device 220 has a second gripping arm 221, on which a second gripping arm 221 is arranged in a space between the two first gripping arms 211.

[0081] The first gripping arms 211 of the first gripping device 210 are movable in a closing direction relative to the second gripping arm 221 of the second gripping device 220 (indicated by the double arrow R). Figure 3 (indicated), to connect or disconnect the clamping jaws 212, 222 with the frame 4, in particular a cross member 5 or a longitudinal member 6 of the frame 2.

[0082] The connecting component 2 further comprises at least one attachment interface 300 for detachable connection with an attachment, in particular the scaffold section 10, wherein the formwork interface 200 and the attachment interface 300 can be operated independently of each other. The provision for the attachment interface 300 for fastening the attachment is well known, so it will not be discussed in detail. The provision for the attachment interface 300 for connection with the scaffold section 10 can, in particular, be a connecting clamp, a pipe clamp, or similar.

[0083] The at least one attachment interface 300 can be connected as an attachment to a scaffold section 10, a stage section, a support, in particular a guide support 13 (as explained below).

[0084] The formwork interface 200 can have a locking mechanism 230 to adjust and / or releasably fix the position of the gripping arms 211, 221 in the closing direction R. The locking mechanism 230 can include a wedge 231, the outer contour of which preferably forms at least a part of a control surface 232.

[0085] Figure 3 shows a side view of the arrangement Figure 2 As from Figure 3 As can be seen, the grooves 7, 8 of the respective longitudinal strut 6 and / or transverse strut 5 have at least approximately the same shape when viewed in cross-section.

[0086] At least one of the gripping arms 211 preferably has a bore 240 for attaching a guide support 13 (see e.g. the Figure 6 , 9 and 10The bore 240, within the scope of the invention, constitutes an attachment interface 300 for connecting, in particular, the alignment support 13 or another support. The attachment interface 300, designed as a bore 240, can also serve to fix tools by means of a carabiner or similar device. Furthermore, instead of a bore 240 in one of the gripping arms 211, the attachment interface 300 can also be formed by hooks or angles in one of the gripping arms 211.

[0087] The example shown below Figure 3 The illustrated connecting component 2 thus has two attachment interfaces 300, one attachment interface 300 being provided or designed for connection to a scaffold section 10 and the other attachment interface 300 for connection to a guide support 13. Additional attachment interfaces 300 or even just one of the two attachment interfaces 300 may also be provided.

[0088] The grooves 7, 8 run in the side surfaces 9 of the respective longitudinal struts 6 and / or transverse struts 5 preferably off-center.

[0089] Furthermore, how from Figure 1 As can be seen, the crossbars 5 have holes 12 spaced apart in their side surfaces 9 from the grooves 7, 8 for liquid drainage. The holes 12 can, of course, also be present in the bars 5, 5a, 6, 6a in other embodiments.

[0090] The first and second gripping arms 211, 221 of the connecting component 2 are, as shown in the Figures 2 and 3 evidently designed to engage in at least two grooves 7, 8 of a respective longitudinal strut 6 and / or transverse strut 5 of the formwork panel 1.

[0091] Figure 4a (and the Figure 4b analogous) show a sectional view through a cross member 5 of a formwork panel 1. In Figure 4a In a highly simplified manner, the crossbar 5 can be seen, which is in Figure 3The cross member 5 is connected to the formwork interface 200 of the connecting component 2. The cross member 5 is shown in a section cut in a plane perpendicular to its longitudinal direction. In the illustration to the left of the cross member 5, the formwork skin 11, which is connected to the frame 4, is also shown in a section. The formwork skin 11 lies flat on the left-facing side or front of the cross member 5. In the background, a longitudinal strut 6, which is connected to the sectioned cross member 5, can be seen in some areas. The illustration also shows the two gripping arms 211, 221 of the gripping devices 210, 220 of the connecting component 2, which are connected to the cross member 5 by a force-fit and form-fit connection. The cross member 5 is formed by a profile tube which has the shape of a bone or an "H".On both the upward-facing and downward-facing sides of the cross member 5 shown in the illustration, a groove 7, 8 is visible, extending longitudinally along the cross member 5, i.e., into the plane of the drawing. The grooves 7, 8 have an identical rectangular cross-section. The two grooves 7, 8 are arranged symmetrically and opposite each other on the cross member 5. The areas of the gripping arms 211, 221, which are located in... Figure 4aThe gripping arms 211, 221 shown are identical in design. Both gripping arms have a projection or a clamping jaw 212, 222 at their tip, which faces left in the illustration. This jaw forms a section that engages in one of the grooves 7, 8. As can be seen, the clamping jaws 212, 222 have a projection at their front ends designed to engage in the grooves 7, 8 of the frame 4. In the illustrated embodiment, the lower of the two gripping arms 221 is movable in a direction parallel to the formwork skin 11, thus allowing the distance between the two gripping arms 211, 221 to be adjusted. To create a connection between the formwork interface 200 and the formwork panel 1, the lower gripping arm 221 is moved in the direction symbolized by an arrow in the illustration.In the closing direction R, the gripping arms 211 and 221 are moved vertically downwards so that the distance between the two clamping jaws 211 and 212 is greater than the width of the crossbar 5 in the vertical direction. The two gripping arms 211 and 221 are then partially pushed over the crossbar 5 until the clamping jaws 212 and 222 are adjacent to the two grooves 7 and 8. The lower gripping arm 221 is then moved towards the upper gripping arm 211, reducing the distance between the two gripping arms 211 and 221. During this movement, the two projections or clamping jaws 212 and 222 engage in a groove 7 and 8, creating a positive fit. In this state, in which the two clamping jaws 212, 222 already form a positive fit with the grooves 7, 8, the connecting component 2 can be moved parallel to the direction of the grooves 7, 8 along the cross member 5 until the desired relative position between connecting component 2 and cross member 5 is reached.The lower gripping arm 221 is then moved towards the upper gripping arm 211 until both gripping arms 211 and 221 clamp the cross member 5.
