Title:

Installation on scaffolding with pre-built staircases

The invention relates to a device on scaffolds constructed from standpipes and walkable levels with pre-built staircases for the transition to the lower or upper end of the individual staircase to the respective scaffold levels.

When using general types of scaffolding, it is necessary for people to be able to reach the individual work levels safely at any height. One way to do this is to use stair towers or staircases built in front of the scaffolding from the outside. The transition from a staircase to the respective scaffolding level results in a more or less large gap in the foot area, which presents safety risks and problems and is not permitted depending on the gap width. According to safety regulations, side protection is required in both the scaffolding and the staircase.

The present invention is based on the object

to create a device of the type mentioned above, with which the aforementioned crossings can be secured without any problems and by means of which it is also possible to easily attach system-compatible railing posts and toe boards and railing beams to these.

To solve the problem, a device of the type mentioned at the beginning is proposed, which is characterized by an intermediate crossbeam in the form of a rectangular transition plate, which has a scaffold coupling on one side for fastening to the vertically running standpipe of the scaffolding cell and a scaffold coupling on the other side for fastening to the vertically running standpipe of the staircases, with two pipe connectors being provided on the opposite side of the transition plate, to which system-compatible railing posts for railing bars and toe boards arranged thereon can be fastened.

The device according to the invention achieves the significant advantage that the transition from the staircases to the individual scaffolding levels is safe. The additional pipe connectors make it possible to create additional side protection using railing posts and railing bars and toe boards that can be attached to them.

According to a special embodiment, the axis dimension between the standpipes and the pipe connectors can be approximately 500 mm, which makes it possible to use system components with a nominal width one meter less than the initial width

The device according to the invention will be explained in more detail using the example of a preferred embodiment with reference to the drawings.

In the drawings

Fig. 1 is a basic side view of a scaffold with the device according to the invention.

Fig. 2 shows a top view of the scaffold according to Fig. 1.

Fig. 3 shows a perspective view of the cross member for the device according to the invention.

As can be seen from the figures in the drawings, the scaffolding consists of vertically running uprights 1, to which scaffolding levels 2 are attached horizontally by any construction. The individual scaffolding levels are secured to the outside by so-called toe boards 3 to prevent people from walking on them.

In front of the scaffold shown in this way, several staircases 4 are arranged according to its height. The transition from each staircase 4 to the respective scaffold level 2 results in a more or less large gap 5 in the foot area due to the system. This presents safety risks and problems and is therefore not permitted. In addition, side protection is required both in the scaffold and in the staircase.

For this reason, according to the invention, an intermediate crossbeam in the form of a rectangular transition plate 6 is provided at the lower and upper end of the staircase 4. The transition plate 6 has a scaffold coupling 7 on each side for attachment to the vertically running

Standpipe 8 of the staircase 4 and a scaffold coupling 9 for attachment to a standpipe 1 of the scaffold cell. This ensures that the transition plate 6 of the intermediate crossbeam can be attached at the same level as the scaffolding deck and the stair landings. This ensures that the safety-related permissible openings of the gaps between the stair landing and the scaffolding level or scaffolding deck are maintained.

On the opposite side, two pipe connectors 10 and 11 are attached to the transition plate 6. System-compatible railing posts and railing bars and toe boards 12 can be attached to these in both directions.

If, when designing the transition plate serving as an intermediate cross member, the dimension between the standpipe 8 and the pipe connector 11 or the standpipe 1 and the pipe connector 10 is selected to be approx. mm, the use of system components with a nominal width one meter below the initial width is possible.
