The present invention relates, among other things, to a working platform and an arrangement of a working platform on a slope surface of reinforced earth. The working platform can additionally or alternatively be used as a protective scaffold and/or safety scaffold

be trained or act.

Reinforced earth is used to construct dams and retaining structures in road and landscape construction. A composite system is formed from reinforcement grids, geotextiles if necessary, and soil material, which has a high load-bearing capacity. The slope surface formed has an inclination that is above the friction angle of the soil material, so that structures made of reinforced earth

typically have slope angles of 60° and more.

Such systems are usually constructed in layers, with each layer having a height of up to 60 cm. Reinforcing elements are mainly made of steel mesh that is pre-bent into a wedge shape, whereby the corresponding wedge angle can correspond to the desired slope angle. After the reinforcement elements have been placed, the soil material is piled up and compacted. Furthermore, the surface is typically covered with a geotextile before the next layer is laid in

is formed in the same way.

When erecting such structures, for reasons of occupational safety,

Provision of fall protection is necessary, especially if the possible

Fall height is more than 2 m. Fall protection for structures made of reinforced earth is known in the state of the art, but these are often time-consuming to install, so that in practice makeshift solutions are often used, which

usually do not provide the necessary security.

In addition, when constructing structures from reinforced earth, work may be required in the slope area or on the edge of the slope. For this purpose, the installation of a work surface or a work platform is required. Conventional fall protection cannot be used for regulatory and/or practical reasons.

can be used as a work surface.

If appropriate, an object of the present invention can now be seen in making the construction of a structure made of reinforced earth safer and more efficient. In particular, this includes providing a work platform for use on the slope surface of reinforced earth, which also serves as a fall protection device. Preferably, this work platform should be easy to install and transport. If appropriate, the work platform should be able to be moved in its entirety, i.e. as a module, and with a lift, which, among other things, enables simple

In this embodiment, the stage surface 17 has a working depth 29 of approximately 100 cm. The stage surface 17 is divided into several surface sections 23 in the form of

of post covering, which is arranged between the two stage legs 3.

The two brackets 2 also each comprise a fastening leg 4 arranged orthogonally to the stage leg 3. The fastening leg 4 in turn comprises a suspension hook 5 arranged in its upper area and a

its lower area arranged support part 8. The hook 5 of the two brackets 2 is each provided with a securing part 10

which is pivotally mounted about a pivot axis 9. The safety part

10 comprises a securing leg 11 which points in the direction of the suspension hook 5.

In the view of Fig. 1, the hook 5 is hooked into a hook part 6, whereby the hook part 6 is arranged on the slope surface 1 of a slope construction made of reinforced earth. The slope surface 1 here has an inclination angle a of

about 80°.

The suspension part 6 is arranged in a suspension area 7 of the suspension hook 5. The safety part 10 is in a locking position in which the safety leg 11

closes the hanging area 7.

The safety part 10 also has a lifting section 14 which is designed to engage a lifting device 15. Together with the attachment points 16 arranged on the railing 19, the work platform can be lifted using a 4-strand chain suspension. The function of the lifting section 14 is

In the case of the safety part 10, the horizontal distance between the center of gravity and the hook 5 is greater than the horizontal distance between the pivot axis 9 and the hook 5. Furthermore, the normal distance between the center of gravity and the hook 6 is greater than the normal distance between the pivot axis 9 and the hook 6. The safety leg 11 therefore hits the hook 6. If no hook 6 were arranged in the hook area 7, the safety leg 11 would swing over or swing into the hook area 7. The indicator section 30

of the securing part 10 would then no longer be parallel to the upper area of the

hook 5 so that incorrect positioning can be easily detected

This position of the safety part is shown in Fig. 5.
