Field of the Invention The present invention relates to a walkable platform for slab construction with parallel ribbed open profiles, which are provided with reinforcing ribs extending from the underside of their floor slabs, with a groove cross section and a roughening formed on the surface of the floor plate, and which profiles on a forehead are attached to a holder, preferably a hollow section, where a front end portion of the slab is provided with a slit. with attachment means for fastening to scaffolding or similar equipment.

Scaffolding made of light alloy alloys are known in various embodiments. In addition to those made of extruded and / or perforated sheets folded on their edges, they also produce strips of ribbed profiles. Taking into account statically determined vertical and horizontal forces, the scaffolds must be designed to withstand the stresses during their use and handling, that is to say, they have to withstand permanent forces, such as shock, without permanent deformation. As a result, the smallest wall thickness cannot be chosen to any degree of thinness, as a result of which scaffolding made of hollow profiles is generally quite heavy. On the other hand, the advantage of using hollow cross sections is their rigidity against torsional forces.

An easier design is provided by the so-called open profile of the plates, which has ribs. The disadvantage of this, however, is that, in contrast to the scaffolds described above, there is a greater tendency for deformation, especially when loading the edge sections. However, if the rim section is designed to be stronger with structural measures, the weight and height of the scaffold will be undesirably increased.

EP-A-0 451 617 discloses a walkable support support hook according to which the support hook is provided with a fastening part, for example a sliding pin, and a support member formed as a downwardly open hook hook. This document does not include the teachings of the frame structure of the walkable deck or the design of the whole of the platform.

U.S. Pat. No. 2,742,121 discloses a planer made of an open profile and having flange holders on both sides and parallel inner supports therein. Above the upper surface, there are a plurality of parallel strips parallel to the reinforcing profiles, and the spaces between the ribs are provided with breakthroughs provided with two parallel flanges extending upwardly. These flange booms are transverse to the reinforcement profiles and rib strips.

Based on this prior art knowledge, it is an object of the present invention to provide a walkable dowel that provides greater strength and stability to known torsion forces and torsion as a result thereof, without substantially increasing the weight of the plank.

The solution of the invention according to the invention can be applied to plain scaffold construction, parallel ribbed open profiles, which are provided with reinforcing ribs protruding from the underside of their floor slabs with reinforcing ribs formed on the surface of the floor slab, and which profiles are connected to a support, preferably a hollow section, on the front side, where the slab is frontal. In this part of the invention, there are means of attachment for fastening to a scaffold element or similar device, the connecting means for the hollow sections, and these hollow sections in the entire width of the board, are rigidly connected to each other, where the height of the profiles corresponds to the height of the board.

The attachment to the scaffold may be, for example, a hook-shaped structural element. Preferably, the plunger is assembled from a plurality of ribbed profiles, which are laid in longitudinal directions, i.e. parallel to the reinforcing ribs, and are attached to a hollow section at the front of the plank, the height of which corresponds to the height of the plunger to ensure torsional strength.

In the case of bending stress, the cross-sectional hollow sections provide the bend with high bending strength. Thus, with regard to strength, a significantly improved strength of the plank can be formed with a low weight according to the open profiles.

In order to provide the desired torsional strength, the height of the hollow section placed in front of the profile or profiles must correspond to the height of the tile, where the heel height is equal to the distance between the lower plane of the base of the reinforcing ribs and the floor plate.

It is preferred that the profile is formed at least at one end by a longitudinal L-shaped perimeter having a shorter stem toward the adjacent reinforcing rib and optionally provided with longitudinal reinforcement ribs on its outside.

A further feature of the invention is that the adjacent profiles can be joined to each other by lateral protrusions and recesses; for example, a first profile is provided with a collar rib protruding from the side of the floor plate, adapted to a shoulder or recess of the second profile, the base of the second profile lying on a collar rib of the first profile, or the collar rib is formed in the form of a hook and extends into the groove of the connector profile.

In a further embodiment, the base-bearing profile of the rectum is formed by a hook strip extending behind the wall of the undercut groove of the other profile, wherein the profiles are fixed to each other in a section of their floor slabs by a groove-to-groove connection, or by force-locking, such as screws, rivets or welding. by.

The invention relates to the secure connection of two adjacent planks. Therefore, the ridge of the edge or rib of one of the planks is formed with at least one bulging or transverse rib, and the ridge of the flange or rib of the adjacent plank is adapted to the bulging or transverse ribs.

HU 214 is equipped with a groove or grooves. In the case of two parallel transverse ribs, the spine of the other profile formed with the receiving grooves has an E-shaped cross section.

The hollow section increases the torsional strength of the plank, and serves also the purpose of having a device attached to the scaffold. Therefore, the hollow section is provided with at least one hook-shaped attachment means, wherein the hollow section and the attachment means are sealed together. This attachment means may be, for example, a ribbed hook profile, to which a trough-shaped section is connected, and which has a concave tube inserted between its two parallel fixing tabs and a hook bar perpendicular to the attachment legs and a ridge plate connecting the fastening legs to define a gap into which the respective rack portion can be inserted.

It is particularly advantageous if the hook profile is directly formed on the sealing tube by way of a ribbon. In this case, the front face of the hollow section opposite to the side of the beam attached to the beam, and the hookhole spaced therefrom, are designed to form a hook-shaped cross-section with a slot for receiving a support of a scaffold, in particular a scaffold.

In a further embodiment of the hollow section, a plurality of hook sections forming one piece with the hollow sections may be formed by cutting the sections of the hook. The fastening legs on the other surface of the rear wall allow the ribbon-shaped profile to be inserted therein, and thus simple assembly.

In order to ensure the rigidity of the hollow section, a diagonal rib is provided in its inner space, which is connected to the rear wall of the hollow section by a slope at an angle of inclination of the hook section formed on the end face of the hollow section, where the inclination angle between the bottom plate and the diagonal rib is preferably 30 °. Due to this diagonal rib, a stable closure is formed whose wall thickness can be chosen relatively thinly, namely between 2 mm and 3.5 mm.

According to a further feature of the invention, the topsheet of the hollow section is substantially parallel to the bottom plate and the upper plane of the joining member connecting the hook section to the front panel is spaced from the top plane of the topsheet.

In another embodiment, the topsheet of the hollow section is inclined at a plane parallel to the bottom plate and extends sloping to the engagement portion of the coupling member and front face, wherein the slope angle is preferably selected from 10 ° to 20 °, thereby forming a direct transition from the floor plate. and the surface of the deeper connecting member of the hook.

In another embodiment of a rectangular tube, two mutually aligned holes are pressed in two opposing walls of the hollow section, the extruded extruded flanges extending into the sleeve receiving the fastening element, which may be in the form of pins attached to the scaffold. .

In order to ensure that the floorboard is non-slip, there are breakthroughs, the edges of which are partially folded upwards, partially downward, where two opposing breakthrough edges are pressed up or down in the same sense, and / or the perforations of the breakthroughs in the same direction are 90 ° rotated relative to adjacent breakthroughs in the same direction.
