Description

[0001] The present invention relates to a bracket for a railing post for fastening to a slab formwork element of a slab formwork, in particular a prefabricated slab formwork. Furthermore, the invention relates to a slab formwork system comprising a slab formwork element.

[0002] It is well known that slab formwork should be equipped with safety devices to prevent people from falling. Installing these safety devices is a significant challenge and time-consuming.

[0003] The document WO 2017 / 178460 A1 shows a safety railing for slab formwork, which has a support clamp for railing posts.

[0004] It is an object of the invention to provide an improved bracket for railing posts on slab formwork. In particular, it is an object of the invention to simplify the assembly and disassembly of such brackets.

[0005] These objects are achieved according to the invention by a bracket for a railing post for attachment to a ceiling formwork and a ceiling formwork system with a ceiling formwork element according to the independent claims. Advantageous embodiments are claimed in the subclaims.

[0006] A first aspect of the invention relates to a holder for a railing post for fastening to a ceiling formwork element of a ceiling formwork, in particular an element ceiling formwork, comprising a receptacle, in particular a hollow profile, for a railing post, a first hook element which is connected to the receptacle in a force-conducting manner, and a locking element which is displaceably mounted on the receptacle and, in a locked position, cooperates with the hook element in such a way that the holder can be detachably connected to the element ceiling formwork by form-fitting.

[0007] A second aspect of the invention relates to a ceiling formwork element comprising a formwork panel with a formwork surface, an edge, in particular of the formwork panel, against which the locking element of the holder can be brought into abutment in the locked position, and a first frame profile, in particular a reinforcement profile, on the side facing away from the formwork surface. At least a first section of the first frame profile in a plane at least substantially parallel to the formwork surface preferably extends parallel to the edge in such a way that a first hook element of a holder for railing posts can engage with the first section.

[0008] A third aspect of the invention relates to a ceiling formwork system with a ceiling formwork element and a holder, wherein the ceiling formwork has, on the side facing away from a formwork surface, a first frame profile and / or a second frame profile, in particular reinforcement profiles, which extend at least partially in a plane that is at least substantially parallel to the formwork surface, and wherein, when the first hook element is in engagement with the first frame profile and / or the second hook element is in engagement with the second frame profile of the ceiling formwork element, the locking element can be brought into abutment with an edge of the element ceiling formwork in the locked position in such a way that a positive connection exists between the holder and the ceiling formwork element.

[0009] Furthermore, the disclosure relates to a method for mounting a bracket on a ceiling formwork element, comprising the following steps: Bringing the bracket to the edge of the slab formwork element with the locking element in an open position; Lifting the bracket in a direction perpendicular to the formwork surface; Hanging the first hook element into the first section of the first frame profile and / or a second hook element into a second section of a second frame profile by a movement of the holder in a direction at least substantially parallel to the formwork surface; and Moving the locking element into a locked position, whereby the bracket is releasably connected to the element slab formwork by form-fitting.

[0010] An element ceiling formwork within the meaning of the invention is preferably a ceiling formwork in which formwork panels and frames are realized in a single ceiling formwork element.

[0011] Force-conducting, in the sense of the invention, preferably means that two elements are connected directly or indirectly in such a way that a force can be transmitted between them. In particular, one element is supported on the other element.

[0012] The invention is based on the realization that large forces and moments occur at the foot of a railing when a person leans on it or is held back by it.

[0013] The invention pursues the approach of using the bracket to clamp the slab formwork elements together through a positive fit. This clamping is functionally achieved by hooking the bracket onto the frame profiles of the slab formwork elements and simultaneously supporting the bracket against the edge of the slab formwork elements.

[0014] For this purpose, hook elements are attached to the bracket, which extend laterally from the bracket's receptacle and engage behind the frame profiles. A locking element is slidably mounted on the bracket. In a locked position, the locking element rests against the edge of the slab formwork elements by means of a positive fit. In an open position, it does not interact with the slab formwork element, allowing the bracket to be removed from the slab formwork element.

[0015] In addition to the positive fit, the edge of the slab formwork elements is also clamped, preferably by engaging behind the frame profiles and supporting the edge in essentially opposite directions. This allows for a largely play-free attachment of the bracket to the slab formwork elements.

[0016] The invention offers a simple and cost-effective solution for providing a ceiling formwork with a bracket for a railing: The bracket can first be hooked onto the frame profiles of the slab formwork element and then secured to the formwork element by moving the locking element from the open position to the locked position. Additional fastening devices such as screws or wedges are not required. This minimizes the number of steps required to attach the bracket to the slab formwork element.

[0017] By using the bracket in conjunction with formwork elements that have a suitable edge and suitable frame profiles, a ceiling formwork system is created that is particularly easy to assemble and at the same time increases the work safety of the fitters.

[0018] The combination of locking element and hook elements blocks only two of the three translational degrees of freedom of movement of the bracket on such a slab formwork element. This offers the advantage that a bracket during assembly can be moved by the installer parallel to the edge of the slab formwork to which it is attached, to another, particularly final, position parallel to the edge.

[0019] Preferably, the first hook element and / or the second hook element are U-shaped. This shape has the advantage of being able to absorb greater loads.

[0020] In an advantageous embodiment of the holder, it has a support element which extends in a first direction away from the receptacle and connects the receptacle to the hook element, wherein the locking element is arranged on one side of the first hook element with respect to the support element.

[0021] The support element acts as a lever arm in order to effectively support an outward-acting force on a safety railing, particularly as seen from the accessible ceiling formwork element.

[0022] Preferably, the first direction is oriented at least substantially perpendicular to a longitudinal axis of the receptacle. Further preferably, the support element is attached to one end of the receptacle. This has the advantage that the available lever arm for force support is fully utilized. Further preferably, the receptacle extends, with respect to the support element, on the same side of the support element as the first hook element and / or the second hook element.

[0023] In a further advantageous embodiment of the holder, the locking element has a projection which projects beyond the locking element on a side on which the first hook element is arranged with respect to the receptacle.

[0024] Preferably, the projection of the locking element of the bracket acts as an attachment point during installation on the slab formwork element. This allows the bracket to be brought into a desired orientation relative to the slab formwork element, preferably by pivoting about a rotation axis formed between the formwork surface and the projection. By subsequently hooking the hook element into the first frame profile and sliding the locking element so that the projection rests against the edge of the slab formwork element, the bracket is securely fixed and cannot tilt.

[0025] In a further advantageous embodiment of the holder, the locking element is captively connected to the holder's receptacle and automatically moves into the locked position in a use position. This is preferably achieved by gravity, but alternative designs that secure the locked position with the aid of a spring force or similar are also feasible. This has the advantage of simplified handling and increases the intrinsic security of the holder.

[0026] In a further advantageous embodiment of the holder, it has a locking device with which the locking element can be secured against displacement on the receptacle. This also increases the security of the holder.

[0027] The securing device preferably comprises a bolt, first bores in the receptacle, and second bores in the locking element, wherein the bolt can be guided through the first bores in the hollow profile and the second bores in the locking element to secure the locking element. Further preferably, the receptacle comprises first bores for defining an open position of the holder and first bores for defining a locked position of the holder. This has the advantage that a secure locking of the holder in a locked position is easy to implement.

[0028] In a further advantageous embodiment of the bracket, it has a second hook element, which is attached to the support element on the same side as the first hook element and at a greater distance from the receptacle than the first hook element, in particular at one end of the support element. This additional attachment point allows the bracket to be more securely attached to a ceiling formwork element.

[0029] In a further advantageous embodiment of the bracket, the first hook element and / or the second hook element has two prongs separated by a gap. The prongs serve to hook the hook elements into the first and / or second frame profiles. Additionally, the prongs can also serve to guide the bracket on the frame profiles during installation. Furthermore, they allow the brackets to be moved in the longitudinal direction of a frame profile.

[0030] In a further advantageous embodiment of the holder, the second hook element has a base arranged between the two prongs. This base can be used to support a force on a frame profile.

[0031] Preferably, the base comes into contact with one, in particular a second, frame profile of the ceiling formwork element.

[0032] In a further advantageous embodiment of the holder, a hook opening of the first hook element and / or a hook opening of the second hook element is oriented toward the receptacle. This has the advantage that the receptacle can be clamped against the edge of the formwork element in such a way that the hooks cannot move out of their hooked position.

[0033] In a further advantageous embodiment of the mount, the support element has a length of approximately 0.2 m to approximately 1.5 m, preferably approximately 0.4 m to approximately 1.0 m, and most preferably approximately 0.7 m. This has the advantage that a sufficiently large lever arm is available for force support, yet opposing or corner-arranged mounts do not interfere with each other.

[0034] In an advantageous embodiment of the formwork element according to the second aspect of the invention, the first frame profile is arranged in the region of the edge. This facilitates the process of hanging the bracket into the slab formwork element during assembly.

[0035] In a further advantageous embodiment, the slab formwork element has a second frame profile, in particular a reinforcement profile, on the side facing away from a formwork surface, which is oriented perpendicular to the edge. The second hook element can be engaged with this second frame profile, resulting in an improved distribution of the supporting forces.

[0036] In an advantageous embodiment of the ceiling formwork system according to the third aspect of the invention, the first hook element and / or the second hook element are oriented such that they can engage with a first frame profile of the ceiling formwork element upon movement of the support element in the direction of the receptacle. This has the advantage of simplified assembly.

[0037] Preferably, the first hook element and / or the second hook element are designed in such a way as to encompass a first portion of the frame profile which is arranged on the side facing away from a ceiling formwork element of the ceiling formwork.

[0038] Further features and advantages of the invention will become apparent from the following description with reference to the figures, which show, at least partially schematically: Fig. 1 shows a first embodiment of a ceiling formwork system in a perspective view; Fig. 2a shows a first embodiment of a holder in a first perspective view; Fig. 2b shows the first embodiment of a holder in a second perspective view; Fig. 3a shows a second embodiment of a ceiling formwork system in a first perspective view; Fig. 3b the second embodiment of a ceiling formwork system in a second perspective view; Fig. 4 shows the second embodiment of a slab formwork system in five side views (a) to (e), which illustrate a process of mounting the bracket; and Fig. 5 an embodiment of a method for mounting a bracket on a ceiling formwork element.

[0041] Document DE10 2022 206 972 describes a method for assembling a slab formwork element 100 of a panel slab formwork system, designed as a formwork table element. The content of document DE10 2022 206 972 is incorporated herein by reference. Preferably, the bracket 1 is mounted on a slab formwork element 100 before a panel slab formwork system is assembled using such a method.

[0042] Fig. 2a and Fig. 2b show an embodiment of a holder 1 in two perspective views.

[0043] The bracket 1 has a receptacle 4, which in the illustrated embodiment is designed as a hollow profile and can accommodate a railing post 2 (not shown). Furthermore, the bracket 1 has a first hook element 5, which is connected to it in a force-conducting manner, and a locking element 6, which is slidably mounted on it.

[0044] Preferably, the holder 1 also has a support element 7, which extends away from the receptacle 4 in a first direction A. The first hook element 5 is attached, in particular welded, either directly to the hollow profile 4 or indirectly via the support element 7 to the hollow profile 4. Furthermore, the first hook element 5 can also be attached to both elements.

[0045] The locking element 6 is arranged on one side of the first hook element 5 with respect to the support element 7.

[0046] The locking element 6 interacts with the first hook element 5 in such a way that the holder can be releasably connected to a ceiling formwork (not shown) by means of a positive fit.

[0047] Preferably, the holder 1, as shown in Fig. 2a and Fig. 2b, a second hook element 10. The second hook element 10 is also preferably firmly connected to the support element, for example by a welded connection.

[0048] Further preferably, the locking element 6 has a safety device 9 with which the locking element 6 can be secured against displacement on the receptacle 4. The safety device 9 has, as in Fig. 2a and Fig. 2b, preferably comprises a bolt 14, a first bore 12b in the receptacle 4, and second bores 13 in the locking element 6. To secure the locking element 6, the bolt 14 can be guided through the first bore 12b in the hollow profile 4 and the second bores 13 in the locking element 6. The first bores 12a of the receptacle 4 serve to lock a railing post to the bracket 1.

[0049] The hollow profile 4 has a first bore 12b (not shown) for defining a locked position of the holder 1. This has the advantage that a secure locking of the holder 1 in a locked position can be easily carried out.

[0050] Further preferably, the bolt 14 of the securing device 9 is secured against slipping out with a split pin 15.

[0051] As in Fig. As shown in Figure 2b, the first hook element 5 has two prongs 16a, 16b, each designed as a hook. A recess is formed between the two prongs 16a, 16b. Accordingly, the second hook element 10 also has two prongs 17a, 17b, each also designed as a hook.

[0052] The Fig. 3a and Fig. 3b show a second embodiment of a ceiling formwork system 200 in two perspective views.

[0053] Fig. 3a shows a slab formwork element 100 with a formwork panel 101 and a formwork surface 102. A first frame profile 104 is arranged at the edge 103 of the slab formwork element 100, to which brackets 1 for railing posts 2 (not shown) are attached. Preferably, the frame profile 104 is designed as a frame element. The formwork panel 101 is preferably inserted into this frame element. Preferably, the edge 103 is formed by the formwork panel 101 and / or the frame profile 104.

[0054] Fig. Figure 3b shows the same arrangement from a side facing away from the formwork surface 102. The support elements 7 extend, as already described with respect to the Fig. 2a and the Fig. 2b, preferably perpendicularly away from the receptacle 4, wherein the first hook element 5 engages around the profile of the frame profiles 104.

[0055] Hook openings, which are defined by the hooks 16a, 16b, 17a, 17b of the hook elements 5, 10, are preferably oriented toward the receptacle 4. In cooperation with the locking element 6, in particular with its projection 8, which rests against the edge 103, a positive connection of the holder 1 with the ceiling formwork element 100 preferably results.

[0056] The first direction A of the support elements 7 of the brackets 1 can be aligned vertically or parallel with respect to second frame profiles 105, which stiffen the slab formwork element 100: When mounting the holder 1 in which the support elements 7 are aligned parallel to the second frame profiles 105, the base 11 of the second hook element 10 is preferably supported on a second frame profile 105.

[0059] Fig. 4 shows a third embodiment of a ceiling formwork system 200 in five side views (a) to (e), which illustrate the process of mounting the bracket 1.

[0060] Preferably, the holder 1 is first placed with the projection 8 of the locking element 6 on the edge 103 of the ceiling formwork element 100, as shown in Fig. 4a. The projection 8 rests on the formwork surface 102, which simplifies handling. Furthermore, a pin 19 in the holder 4, by engaging in the second bore 13 of the locking element 6, prevents the locking element 6 from slipping out of the holder 4. The holder 1 is then moved toward the formwork panel 101; in other words, the holder 1 is lifted until the hook elements 5, 10 rest against the frame profiles 104, 105 ( Fig. 4b).

[0061] Subsequently, the holder 1 is preferably pulled away from the ceiling formwork element 100 so that the prongs 16a, 17a of the hook elements 5, 10 engage in those areas of the frame profiles 104, 105 which are aligned parallel to the formwork surface 102 ( Fig. 4c).

[0062] Following this, the locking element 6, which is designed as a tubular section, is preferably displaced on the receptacle 4 in the direction of the hook element 5, so that the end face of the projection 8 rests against the edge 103 ( Fig. 4d).

[0063] Finally, the locking element 6 is secured in its locked position by means of the securing device 9 by inserting its bolt 14 into the bores 12a, 13 and by securing it with its split pin 15 (not shown) ( Fig. 4e).
