Description

Formwork panel and system for forming a wall element

The present application claims the priority of German Patent Application No. 10 2021 120 438.0 and the priority of German Patent Application No. 10 2021 120 441.0, the contents of which are incorporated herein by reference in their entirety.

The invention relates to a formwork panel having a frame which has a number of longitudinal struts and a number of transverse struts, the longitudinal struts and the transverse struts being arranged essentially perpendicularly to one another. The invention also relates to a system for shuttering a wall element, comprising at least one shuttering panel.

The invention relates to the field of construction. When erecting or remodeling buildings, building parts are often formed by pouring concrete. The shape of these cast building parts is specified by a formwork, the formwork being erected on the construction site before the casting. In particular, ceilings or walls of a building are erected with the help of formwork.

When constructing high walls or wall elements, scaffolding is required in order to be able to prepare the formwork for the construction of the wall element. On the one hand, scaffolding is required 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 one another by anchors before the production of a wall element in order to absorb the outward pressure of the poured concrete material. For this purpose, the formwork panels must be accessible to workers over their entire height, which is usually done using scaffolding or a working platform. Furthermore, in most cases, before the wall element is produced, reinforcement must be attached to an already positioned formwork or between such a formwork and a closing formwork which is opposite the formwork.

According to the state of the art, scaffolding or working platforms that are provided for attaching formwork locks are arranged on the formwork in such a way that no reinforcement can be attached to these scaffolding or working platforms. The places where the reinforcement must be positioned are simply not accessible from these scaffolding or work platforms used to prepare the formwork panels, since they are on the opposite side of the formwork panel. In practice, this means that a first type of scaffolding is required to operate the formwork and a second type of scaffolding is required to position and insert the reinforcement into the formwork. In addition, there are usually a large number of different types of scaffolding and formwork panels on the construction site, which often means that the scaffolding cannot be connected to the formwork panels, in particular for the applications described above. Differences in the grid, which exist between the scaffolding systems and the formwork systems, usually prove to be problematic. In many applications, after the wall element has been poured using the formwork, work must still be carried out on the wall element after the formwork has been removed, for example the filling of anchor holes or plastering or painting work. In order to be able to reach the wall element over its entire height, scaffolding or a work platform is required again after the actual casting in order to be able to carry out the final work. A large number of different scaffolding or work platforms are therefore required for the production of a wall element using formwork, which leads to complicated work processes and the need for a large number of different scaffolding elements. In addition, it is also necessary to provide the formwork panels with push-pull supports.

The object of the present invention is therefore to simplify the production of a wall element, in particular to enable flexible, universal and/or secure attachment of scaffolding, platforms and/or supports to formwork panels.

The object is achieved by claim 1 according to the invention.

According to the invention, a formwork panel is proposed, having a frame which has a plurality of longitudinal struts and a plurality of transverse struts, the longitudinal struts and the transverse struts being arranged essentially perpendicularly to one another, with at least some of the longitudinal struts and/or the transverse struts having at least two grooves running in the longitudinal direction and run on opposite side surfaces of the respective longitudinal strut and/or transverse strut.

The transverse and/or longitudinal struts (hereinafter collectively referred to as struts) have, geometrically speaking, two indentations on both sides, which serve as rails. In cross-section, the profile of the depression has the shape of a bone. As a result, different scaffolding, platforms and / or supports, in particular push-pull supports, can be easily and safely attached to formwork panels, for example by means of a connecting component, e.g. B. a clamping device are attached. The connecting component which z. B. adapted to the profile includes gripping devices or grippers can be variably attached to the frame and removed. Scaffolding, platforms and/or supports, in particular push-pull supports, can thus be flexibly connected for aligning the formwork.

It has been shown that, with the solution according to the invention, not only scaffolding and platforms, but also supports, in particular push-pull supports, can be fixed in a suitable manner.

Viewed in the cross section of the respective longitudinal strut and/or transverse strut, the grooves can be arranged axially symmetrically to one another and/or arranged opposite one another.

Viewed in the cross section of the respective longitudinal strut and/or transverse strut, the grooves can have at least approximately the same shape.

The grooves can extend at least over part of the length or over the entire length of the respective longitudinal strut and/or transverse strut. It has turned out to be particularly suitable if the grooves extend over the entire length of the respective strut. As a result, connection components, for example clamping devices, can be fixed to the frame in a particularly advantageous and flexible manner.

The side surfaces of the respective longitudinal strut and/or transverse strut, in which the grooves are arranged, can run essentially perpendicularly to a front side of the frame provided for the attachment of a formwork skin.

The formwork panel can have a formwork skin which, when connected to the frame, rests on at least part of the longitudinal struts and/or the transverse struts, in particular on a front surface which is oriented forward and runs plane-parallel to the formwork skin.

The frame can have two outer frame transverse struts and two outer frame longitudinal struts, between which inner transverse struts and/or inner longitudinal struts are arranged, with preferably a part of the inner longitudinal struts and/or the inner transverse struts having the grooves.

All inner transverse struts and/or all inner longitudinal struts preferably have the grooves. The outer frame transverse struts and/or the outer frame longitudinal struts preferably have no grooves.

In a particularly advantageous embodiment of the formwork panel, it can be provided that at least some of the inner transverse struts, preferably all of the inner transverse struts, have grooves and the inner longitudinal struts have no grooves. It has proven to be particularly suitable for fixing scaffolding, platforms, supports, in particular props, if these can be fixed to the cross braces, in particular to the inner cross braces. An additional attachment to the longitudinal struts is usually not necessary.

The grooves can run eccentrically in the side surfaces of the respective longitudinal struts and/or transverse struts.

Preferably, the grooves in the side faces run at a constant distance from the edges of the side faces, i. H. the edges of the side surfaces, in which the side surfaces converge with a front surface and a rear surface of the struts.

The grooves preferably run off-centre in the side surfaces in such a way that the grooves are at a greater distance from a front edge of the struts, in which the side surfaces converge with a front surface, than from a rear edge of the struts, in which the side surfaces converge with the rear surface. Due to the fact that the grooves run eccentrically in this way, a connecting component or a clamping device can be fixed in the grooves in a particularly advantageous manner. It is advantageous if the longitudinal struts and/or the transverse struts have holes in the side surfaces that are spaced apart from the grooves.

This ensures that liquids, such as rainwater, can drain off.

The holes are preferably made in a part of the side faces located between the grooves and the front edge.

The side walls of the respective grooves can be inclined outwards from a groove base of the respective grooves, in which case the side walls can preferably enclose an angle of 95° to 125°, in particular 110°, with the groove base.

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

The inventor has recognized that this geometry allows connecting components to be fixed in the grooves in a particularly simple and non-twisting manner, preferably by means of clamps.

Claim 13 specifies a system for forming a wall element, comprising at least one formwork panel with a frame having a number of longitudinal struts and a number of transverse struts and at least one connecting component which has a formwork interface for detachable connection to the frame of the formwork panel.

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.

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 to connect or disconnect the jaws from the frame.

According to the invention, the system provides that the formwork panel is a formwork panel according to one of Claims 1 to 12 and/or one of the embodiments described above and the first and second gripping arms of the connecting component are designed to fit into the at least two grooves of a respective longitudinal strut and/or intervene cross brace of the formwork panel.

Such a system has proven to be particularly suitable for fixing scaffolding, platforms and supports, in particular push-pull supports, in a flexible, safe and simple manner.

Advantageous features of a connection component for the system are given below. A connection component is proposed, having a formwork interface for detachable connection to a frame of a formwork panel, the formwork interface comprising a first gripping device having at least a first gripping arm with a clamping jaw and a second gripping device having at least a second gripping arm with a clamping jaw, the first gripping arms of the first gripping device can be moved in a closing direction relative to the second gripping arms of the second gripping device in order to connect or release the clamping jaws to the frame and having at least one attachment interface for detachable connection to an attachment, the formwork interface and the attachment interface being operable independently of one another .

These measures create a combination between a formwork interface and an attachment interface, with which a large number of different types of scaffolding, platforms, supports, etc. can be connected in an advantageous manner.

The attachment interface can be connectable to a scaffolding section, a stage section, a support, in particular an alignment support, as an attachment.

The shuttering interface may include a locking mechanism to adjust and/or releasably fix the position of the gripping arms in the closing direction.

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

This measure provides a simple and at the same time secure locking option.

The two gripping devices can each have recesses which at least partially overlap one another and into which the wedge can be inserted or has been inserted.

The wedge can be arranged captively in the recesses, with the wedge preferably having stops projecting beyond the recesses at its front ends in order to form the captive device.

The first gripping device can have two first gripping arms and the second gripping device can have a second gripping arm.

This creates a stable connection.

The gripping arms can run plane-parallel and spaced apart from one another, and the second gripping arm can be arranged in a space between the two first gripping arms.

There may be at least one bolt bridging a gap between the first gripping arms and arranged to act as a stop for the second gripping arm. It is advantageous if the clamping jaws have a projection at their front ends which is designed to engage in grooves in the frame.

As a result, the gripping device can be captively fixed to the longitudinal and/or transverse struts of the frame of the formwork panel.

The formwork interface and at least one of the attachment interfaces can be releasably connected to one another, the formwork interface and the attachment interface preferably each having a contact surface with an elongated hole, and a fastening element being insertable through the elongated holes in order to detachably connect the contact surfaces to one another.

The fastening element can be materially connected to the contact surface of the attachment interface and/or one of the first gripping arms can have a projection which is designed and arranged in such a way that rotation of the fastening element is limited by the projection.

The integral connection of the fastening element to that of the attachment interface can preferably be produced by welding.

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 bottom of a rail with a U-shaped cross section.

At least one of the add-on part interfaces can have a hole for attaching an alignment support.

Alternatively or additionally, at least one of the first and/or second gripping arms can have the bore.

Advantageous refinements and developments of the invention result from the dependent claims.

Elements with the same function are provided with the same reference symbols in the figures.

FIG. 1 shows a formwork panel 1 which, together with connecting components 2, forms a system 3 for forming a wall element, which is not shown. The formwork panel 1 has a frame 4 which has a plurality of transverse struts 5 and a plurality of longitudinal struts 6, the longitudinal struts 6 and the transverse struts 5 being arranged essentially perpendicular to one another. At least part of the longitudinal struts 6 and/or the transverse struts 5 has at least two grooves 7, 8 which run in the longitudinal direction and on opposite side surfaces 9 of the respective longitudinal strut 6 and/or transverse strut 5. Only the upper side surfaces 9 of the cross braces 5 with the grooves 7 are visible in FIG. Also, only the cross braces 5 are provided with the grooves 7 . The grooves 8 on the lower side surfaces 9 of the cross braces 5 can be seen in more detail in FIG. As further shown in FIG. 1, a scaffolding section 10 with vertical posts 10a and horizontal bars 10b is attached to the formwork panel 1 by means of the connecting components 2 .

As can also be seen from FIG. 1, the formwork panel 1 has a formwork skin 11 which, in a state connected to the frame 4, rests on at least 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 perpendicularly to a front side of the frame 4 intended for attachment of the formlining 11. The frame 4 comprises two outer frame transverse struts 5a and two outer frame longitudinal struts 6a, between which the inner transverse struts 5 and/or the inner longitudinal struts 6 are arranged, the inner transverse struts 5 having the grooves 7,8.

All inner transverse struts 5 and/or all inner longitudinal struts 6 can have the grooves 7, 8 and the outer frame transverse struts 5a and/or the outer frame longitudinal struts 6a cannot have any grooves 7, 8.

In the present exemplary embodiment, all of the inner cross braces 5 include the grooves 7, 8.

FIG. 2 shows a transverse strut 5 of a formwork panel 1 (not shown in FIG. 2) with a connecting component 2 which engages in the grooves 7, 8 of the transverse strut 5. In a further exemplary embodiment, the transverse strut 5 could also be a longitudinal strut 6 . The grooves 7, 8 are viewed in cross section of the respective longitudinal strut 6 and/or transverse strut 5 arranged axially symmetrically to one another and arranged opposite one another.

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

The connection component 2 has a formwork interface 200 for detachable connection to 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). The first gripping arms 211 of the first gripping device 210 can be moved in a closing direction relative to the second gripping arms 221 of the second gripping device 220 (indicated by the double arrow R in Figure 3) in order to connect or release the clamping jaws 212, 222 to the frame 4 . The connecting component 2 also has an attachment interface 300 for detachable connection to an attachment, in particular the scaffolding section 10, it being possible for the formwork interface 200 and the attachment interface 300 to be operated independently of one another. The inclusion of the add-on part interface 300 for fastening the add-on part is well known, so that it will not be discussed in detail.

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

FIG. 3 shows a side view of the arrangement from FIG. 2. As can be seen from FIG almost the same shape. At least one of the gripping arms 211 has a bore 240 for attaching an alignment support 13 (see FIGS. 6, 9 and 10).

The grooves 7, 8 run eccentrically in the side surfaces 9 of the respective longitudinal struts 6 and/or transverse struts 5.

As can also be seen from FIG. 1, the transverse struts 5 in the side surfaces 9 have holes 12 spaced apart from the grooves 7, 8 for liquid drainage. Of course, the holes 12 can also be present in the struts 5, 5a, 6a in other exemplary embodiments.

As can be seen from FIGS. 2 and 3, the first and second gripping arms 21 1 , 221 of the connecting component 2 are designed to engage in the at least two grooves 7 , 8 of a respective longitudinal strut 6 and/or transverse strut 5 of the formwork panel 1 .

FIG. 4 shows a sectional view through a cross brace 5 of a formwork panel 1 . In FIG. 4, the cross brace 5 can be seen in a greatly simplified manner, which is connected to the formwork interface 200 of the connecting component 2 in FIG. The cross brace 5 is shown in section in a plane perpendicular to its longitudinal direction. In the illustration to the left of the cross brace 5 , the formwork skin 11 , which is connected to the frame 4 , can also be seen in section. The shift skin 11 lies flat on the left-hand side or front side of the cross braces 5 . A longitudinal strut 6 can be seen in some areas in the background, which is connected to the sectioned transverse strut 5 . 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 brace 5 in a non-positive and positive manner. The cross brace 5 is formed by a profile tube which has the shape of a bone. A groove 7, 8 can be seen on the side of the cross brace 5 pointing upwards in the illustration and on the side pointing downwards in the illustration, which extends in the longitudinal direction of the cross brace 5, ie in the illustration into the plane of the drawing. The grooves 7, 8 here have an identical, rectangular cross section. The two grooves 7, 8 are arranged symmetrically in the vertical direction and opposite one another on the cross brace 5. The areas of the gripper arms 211, 221, which are shown in Figure 4, are identical. Both gripping arms 211, 221 have a projection or a clamping jaw 212, 222 on their tip, which faces to the left in the illustration, which here forms an area which engages in one of the grooves 7, 8 in each case. In the embodiment shown, the lower of the two gripping arms 221 is designed to be movable in a direction parallel to the formwork skin 11, as a result of which the distance between the two gripping arms 211, 221 is designed to be adjustable. To establish a connection between the formwork interface 200 and the formwork panel 1, the lower gripping arm 221 is moved vertically downwards in the direction symbolized by an arrow in the illustration or in the closing direction R, so that the distance between the two clamping jaws 211, 212 is greater than the width of the cross brace 5 in the vertical direction. The two gripper arms 211, 221 are then partially pushed over the cross brace 5 until the clamping jaws 212, 222 are adjacent to the two grooves 7, 8. The lower gripping arm 221 is then moved towards the upper gripping arm 211 and the distance between the two gripping arms 21 1 , 221 is reduced. The two grab it Projections or clamping jaws 212, 222 each in a groove 7, 8, whereby a form fit is created. 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 displaced parallel to the direction of the grooves 7, 8 along the crossbar 5 until the desired relative position between Connection component 2 and cross member 5 is reached. The lower gripping arm 221 is then moved towards the upper gripping arm 211 until the two gripping arms 211 , 221 clamp the cross brace 5 . In this state, there is also a frictional connection between the clamping element or the formwork interface 200 of the connecting component 2 and the cross brace 5 . The described adjustability of the relative position of the connecting component 2 along the grooves 7 , 8 is particularly advantageous for a flexible connection between the connecting component 2 and the formwork panel 1 . Such a connection can also be made between a connecting component 2 and a longitudinal strut 6 . In the background, a groove 7 is also arranged on the longitudinal strut 6 shown, which is aligned with the grooves 7, 8 of the transverse strut 5.

FIG. 5 shows a perspective detailed view of a further embodiment of a formwork interface 200 of a connecting component 2. The connecting component 2 of the embodiment illustrated in FIG. The size and shape of the cross section of the pipe section of the intermediate post 10c corresponds to the shape and size of a vertical post 10a of the scaffolding section 10. The two gripping arms 211, 221 of the formwork interface 200 and the locking mechanism 230 are arranged on the intermediate post 10c and with a cross brace 5 of the formwork panel 1 connected (not shown). The scaffolding section 10 is connected via a scaffolding interface (not designated in more detail) on the intermediate post 10c via a horizontal bar 10b.

FIG. 6 shows a perspective detailed view of a cross brace 5 into which a connecting component 2 is clamped. Furthermore, an alignment support 13 is attached to the bore 240 of the gripping arm 211 of the connecting component 2 .

FIG. 7 shows a perspective detailed view of a cross brace 5 to which a frame section 10 is connected by means of the connecting component 2.

FIG. 8 shows a simplified sectional view through a longitudinal strut 6 or a transverse strut 5 of the frame 4 of the formwork panel according to the invention. The dimensions here are to be understood as purely exemplary and not restrictive, but have turned out to be advantageous.

The side walls 7b, 8b of the respective grooves 7, 8 are inclined outwards from a groove base 7a, 8a of the respective grooves 7, 8, the side walls 7b, 8b preferably having an angle of 95° to 125° with the groove base 7a, 8a. include in particular 110 °.

Furthermore, the grooves 7, 8 can have a depth of 9 mm to 16 mm, preferably 13 mm. FIG. 9 shows a perspective view of a system 3 for shuttering a wall element. There is both a scaffolding section 10 with vertical posts 10a, a horizontal bar 10b and a tread 10d as well as props 13. FIG. 10 shows a side view of a system 3 for shuttering a wall element.
