Description

The present 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. Furthermore, the invention relates to a ceiling formwork system with a ceiling formwork element and a method for mounting a holder on a ceiling formwork element of a ceiling formwork, in particular an element ceiling formwork.

It is well known that ceiling formwork can be fitted with safety devices to prevent people from falling down. Installing the safety devices is a major challenge and is time-consuming.

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

It is an object of the invention to provide an improved bracket for railing posts on ceiling formwork. A further object is to provide an improved method for mounting such a bracket on a ceiling formwork element. In particular, it is an object of the invention to simplify the assembly and disassembly of such brackets.

These objects are achieved according to the invention by a holder for a railing post for fastening to a ceiling formwork, a ceiling formwork system with a ceiling formwork element and a method for mounting a holder according to the independent claims. Advantageous embodiments are claimed in the subclaims.

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 slidably mounted on the receptacle and, in a locked position, interacts with the hook element in such a way that the holder can be detachably connected to the element ceiling formwork by positive locking.

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.

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 a first frame profile and/or a second frame profile, in particular reinforcement profiles, on the side facing away from a formwork surface, 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.

• Heranführen der Halterung an den Rand des Deckenschalungs-Elements, wobei sich das Verriegelungselement in einer geöffneten Position befindet;

A fourth aspect of the invention 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;

Suspending the first hook element in the first section of the first frame profile and/or a second hook element in a second section of a second frame profile by moving 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 ceiling formwork by form-fitting.

An element ceiling formwork in the sense of the invention is preferably a ceiling formwork, in which formwork panels and frames are realized in a single ceiling formwork element.

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

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.

The invention follows the approach of using the bracket to clamp the ceiling formwork elements by means of a positive fit. This clamping is functionally achieved by hooking the bracket onto the frame profiles of the ceiling formwork elements and simultaneously supporting the bracket on the edge of the ceiling formwork elements.

For this purpose, hook elements are attached to the bracket, which extend laterally from the bracket's mount and engage behind the frame profiles. A locking element is slidably attached to the bracket. In a locked position, the locking element rests on the edge of the ceiling formwork elements by means of a positive fit. In an open position, this does not interact with the ceiling formwork element, so that the bracket can be removed from the ceiling formwork element.

In addition to the positive connection, the edge of the ceiling formwork elements is preferably also clamped by engaging behind the frame profiles and supporting the edge in essentially opposite directions. This allows the bracket to be attached to the ceiling formwork elements with as little play as possible.

• Die Halterung kann an den Rahmenprofilen des Deckenschalungs-Elements zunächst eingehakt werden und dann durch ein Verschieben des Verriegelungselements von der geöffneten Position in die verriegelte Position an dem Schalungs-Element fixiert werden. Weitere Befestigungsmittel, wie Schrauben oder Keile, sind nicht nötig. Dies verringert die Anzahl an Arbeitsschritten zur Befestigung der Halterung an dem Deckenschalungs-Element auf ein Minimum.

The invention offers a simple and cost-effective solution to provide a ceiling formwork with a bracket for a railing:

• The bracket can first be hooked onto the frame profiles of the ceiling formwork element and then fixed 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 necessary. This reduces the number of work steps for attaching the bracket to the ceiling formwork element to a minimum.

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 increases the work safety of the fitters.

The combination of locking element and hook elements only blocks two of three translational degrees of freedom of movement of the bracket on such a ceiling formwork element. This offers the advantage that a bracket that is being assembled can be moved by the fitter parallel to the edge of the element ceiling formwork to which it is attached to another, in particular final, position parallel to the edge.

Preferably, the first hook element and/or the second hook element is U-shaped. This shape has the advantage that greater loads can be absorbed.

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.

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

Preferably, the first direction is aligned 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 to the same side of the support element as the first hook element and/or the second hook element.

In a further advantageous embodiment of the holder, the locking element has a projection which protrudes beyond the locking element on a side on which the first hook element is arranged in relation to the receptacle.

Preferably, the projection of the locking element of the bracket acts as an attachment point when mounting on the ceiling formwork element. This allows the bracket to be preferably pivoted about an axis of rotation which is located between The bracket is securely fixed and cannot tip over by means of the hook element that forms a gap between the formwork surface and the projection in a desired orientation in relation to the ceiling formwork element. By then hanging the hook element in the first frame profile and moving the locking element in such a way that the projection rests on the edge of the ceiling formwork element.

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 position of use. This is preferably achieved by gravity, but alternative designs that secure the locked position using a spring force or similar are also possible. This has the advantage of simplified handling and increases the intrinsic safety of the holder.

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

The securing device preferably has a bolt, first holes in the receptacle and second holes in the locking element, wherein the bolt for securing the locking element can be guided through the first holes in the hollow profile and the second holes in the locking element. The receptacle also preferably has first holes for defining an open position of the holder and first holes for defining a locked position of the holder. This has the advantage that a secure locking of the holder in a locked position can be carried out easily.

In a further advantageous embodiment of the holder, 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 fastening point allows the holder to be attached more securely to a ceiling formwork element.

In a further advantageous embodiment of the holder, the first hook element and/or the second hook element has two prongs which are separated by a gap. The prongs serve to hook the hook elements into the first and/or second frame profiles. In addition, the prongs can also serve to guide the holder on the frame profiles during assembly. They also enable the holders to be moved in the longitudinal direction of a frame profile.

In a further advantageous embodiment of the holder, the second hook element has a base which is arranged between the two prongs. A force can be supported on a frame profile via this base.

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

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 aligned in the direction of the receptacle. This has the advantage that the receptacle can be braced against the edge of the formwork element in such a way that the hooks cannot move out of their hooked position.

In a further advantageous embodiment of the holder, the support element has a length of about 0.2 m to about 1.5 m, preferably from about 0.4 m to about 1.0 m, and most preferably about 0.7 m. This has the advantage that a sufficiently large lever arm is available for force support, but holders arranged opposite one another or at an angle do not get in each other's way.

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

In a further advantageous embodiment, the ceiling formwork element has a second frame profile, in particular a reinforcement profile, on the side facing away from a formwork surface, which is aligned perpendicular to the edge. The second hook element can be brought into engagement with this second frame profile, which results in an improved distribution of the supporting forces.

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 is aligned in such a way that it can be engaged by a movement of the support element in the direction of the receptacle with a first frame profile of the ceiling formwork system. Elements can be engaged. This has the advantage of simplified assembly.

Preferably, the first hook element and/or the second hook element are designed 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.
