Connection element to scaffold node

Description

The invention relates to a scaffold node connection element for diagonal bracing in scaffolding systems. It is a supplementary element for the wedge pocket modular scaffolding according to P 43 14 001.

Wedge pocket modular scaffolds have node elements with the following basic structure:

A node element has four wedge pockets into which wedge-shaped plug elements engage, each of which is attached to the free end of a connection element. In the locked state, the wedge-shaped plug elements protrude downwards from the pockets and have at least one opening in this area for receiving locking elements.

The plug-in elements are designed in a disc shape so that when locked, the underside of the pocket and the lower edge of the plug-in element form an acute angle.

The crossbars can be hooked into the wedge pockets, leading radially away from the scaffolding stand.

The diagonal braces used to improve the statics had to be attached to the scaffolding stand using swivel couplings. This means that special additional elements in the form of these couplings must be available and that a considerable amount of assembly work is required when installing the diagonal braces.

gen is.

Derived from this state of the art, the object of the invention is to equip diagonal struts with coupling elements that enable rapid assembly and disassembly without further additional elements.

This object is achieved according to the invention by the features of the main claim, the subclaims show further advantageous embodiments of the invention.

According to the invention, a wedge plate is welded to the bevelled front sides of the diagonal struts, the shape of which enables it to be inserted/pushed in/hung into a wedge pocket of the scaffolding node.

The surface spanned by the wedge plate rests on the imaginary front surface of the diagonal strut at an acute angle α determined by the diagonal course of the installed diagonal strut.

To secure the diagonal brace suspended in the wedge pocket, the wedge plate attached as the end of the diagonal brace is designed in such a way that, in the suspended position, it protrudes far enough beyond the lower edge of the wedge pocket that a securing element can be put into operation.

According to the preferred embodiment of the invention, the securing element is connected to the wedge plate and thus to the diagonal strut and can be easily brought into the functional position after mounting (hanging) the diagonal strut in the wedge pocket or assumes the functional position solely through the effect of gravity

automatically.

The safety element is a freely movable bracket that is bent at the top and bottom ends, for example at right angles, pointing in the same direction. The upper part of the bracket is guided through an opening in the wedge plate in the front area of the diagonal brace. A locking mechanism on the part of the bracket that is pushed through inside the diagonal brace, for example a cross bolt on the inside of the wedge plate, ensures that the bracket cannot slip out.

In the assembly position, the hook-shaped lower part of the bracket hits the second opening located below the wedge pocket in the wedge plate by gravity alone and penetrates - at least a few mm - into this opening.

The bracket, i.e. the hook-shaped lower part, reaches the final securing position (end position) after a bounce on the back of the bracket.

The bracket can be secured against slipping out of the lower wedge pocket opening by pairing a drill hole in the bracket hook with an inserted split pin.

The invention is described below without limiting the general inventive concept using exemplary embodiments with reference to the drawing, to which reference is expressly made with regard to the disclosure of all details of the invention not explained in more detail in the text. They show:

Fig. 1 shows the scaffold node connection element according to the invention in the installed state. The wedge pockets 3 of the scaffold node are welded to the scaffold stand 11. A diagonal strut 1 is suspended in a wedge pocket 3 by means of a wedge plate 2 welded to the beveled end; the diagonal strut is only shown with its support plan on the wedge plate 2.

The wedge plate 2 has two slot-shaped openings 6 and 9 through which the angled ends 5, 8 (see Fig. 2 and 3) of the safety bracket 4 are guided.

Fig. 2 shows the end piece of a diagonal brace 1 designed according to the invention with a wedge plate 2 and a safety bracket 4, with the safety bracket 4 being shown in the position caused by gravity. The lower hook-shaped part 8 of the bracket 4 is already immersed a few millimeters into the lower wedge plate opening 9. The upper angled part 5 of the freely movable bracket 4 runs through the upper wedge plate opening 6 into the interior of the diagonal brace 1 and is secured against slipping out by a cross bolt 7 while maintaining freedom of movement.
