WORK PLATFORM

[0001] The present invention relates, inter alia, to a working platform and to an arrangement of a working platform on an embankment surface of reinforced earth. The working platform can additionally or alternatively be designed or act as a protective scaffold and/or safety scaffold.

[0002] Reinforced earth is used to construct dams and retaining structures in road and landscape construction. For this purpose, a composite system is formed from reinforcement grids, possibly geotextiles, 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 can typically have slope angles of 60° and more.

[0003] Such systems are usually constructed in layers, with each layer possibly having a height of up to 60 cm. Reinforcing elements used are in particular steel mesh that is pre-bent in 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 formed in the same way.

[0004] When erecting such structures, it is necessary to provide fall protection for reasons of occupational safety, particularly 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 it is often time-consuming to install, so that in practice makeshift solutions are often used, which usually do not offer the necessary safety. Fall protection for reinforced earth is described, for example, in JP H09170235 A.

[0005] Moreover, when constructing structures from reinforced earth, work may be required in the area of the slope or on the edge of the fall. For this purpose, the installation of a work surface or a work platform is required. Conventional fall protection devices cannot be used as a work surface for regulatory and/or practical reasons.

[0006] A fastening device for a scaffolding that can be attached to a wall or roof is described in DE 19641813 A1. The use on reinforced soil is not mentioned in this document.

[0007] 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 easy installation and can prevent individual parts from falling down.

[0008] These and other tasks can be solved with the work platform described here.

[0009] The working platform comprises two consoles, a stage surface and a fall protection device protruding from the stage surface, whereby the fall protection device can form the lower part of a railing. The stage surface has a working depth of at least 100 cm.

[0010] Each of the brackets comprises a stage leg that supports the stage surface and a fastening leg. If necessary, the two legs are arranged essentially orthogonally to each other. A suspension hook is provided on the fastening leg, in particular at its upper end.

[0011] Furthermore, on the fastening leg, in particular at its lower end, a

support part is provided to support the console on the embankment surface.

[0012] The suspension hook is designed to be suspended in a suspension part arranged on the slope surface. For this purpose, a section of the suspension part is introduced into a suspension area of the suspension hook.

[0013] The two brackets also have a securing part which is designed to close off the hanging area or to secure the section of the hanging part inserted into the hanging area in the hanging area. For this purpose, the securing part has a securing leg.

[0014] If necessary, the securing part is pivotally mounted on the fastening leg so that it can be brought into a locking position and a release position. In the locking position, the securing leg closes the hooking area in particular completely, while in the release position the securing leg can at least partially release the hooking area and thus enable the hooking hook to be guided out.

[0015] The safety part is designed in particular in such a way that the safety leg can swing freely into the hooking area or pivot in if no hooking part is arranged in the hooking area. This allows, among other things, a position control of the safety part. In particular, the safety part has a position indicator that shows the position of the safety part. The position indicator can be a section of the safety part that is aligned parallel to a corresponding section of the hooking hook when the safety part is correctly positioned, i.e. in particular when the safety part is in the locked position.

[0016] It can be provided that the center of gravity of the safety part is located below the pivot axis of the safety part in the operating position of the work platform. It can also be provided that the horizontal distance between the center of gravity of the safety part and the suspension hook in the locked position is greater than the horizontal distance between the pivot axis of the safety part and the suspension hook when the work platform is in the operating position. The operating position refers in particular to the position of the work platform in which the platform surface is aligned essentially horizontally.

The safety part can additionally have a locking device to hold the safety part in the locking position. The locking device can be formed from or comprise a locking bolt which is guided in corresponding recesses in the safety part.

[0017] A lifting section is provided on the safety part in order to be able to lift the work platform with a lifting device, for example with a crane hook. The lifting section is designed in particular in such a way that the safety part pivots into the release position when the work platform is lifted on the lifting section. Additional attachment points can also be provided on the work platform for the engagement of a lifting device. The attachment points and lifting section can be designed together to enable the work platform to be lifted with a 4-strand chain sling.

[0018] The support part can be adjustably arranged on the fastening leg. If necessary, the support part can have a T-shape.

[0019] The stage leg can be arranged at any suitable position on the fastening leg, in particular in the area of the suspension hook or in the area of the support part.

[0020] The suspension part can be arranged on the reinforcement grid of a reinforced earth. The reinforced earth can have soil material in addition to the reinforcement grid and a geotextile arranged between the reinforcement grid and the soil material. The suspension part can have two fastening legs and a centrally arranged suspension loop. The fastening legs can hold the suspension part in the reinforcement grid, while the suspension loop protrudes from the reinforcement grid and is ready for hanging the suspension hooks of the work platform.

[0021] The distance between two suspension loops corresponds in particular essentially

the distance between the two hooks of the work platform.

[0022] If necessary, the geotextile can be arranged between the fastening legs and the reinforcement grid. If necessary, the fastening legs can be arranged between the geotextile and the reinforcement grid. In the latter case, additional hooks can be provided for further fastening of the hanging part, into which the fastening legs or the hanging part are hooked. The additional hooks run in particular transversely to the fastening legs.

[0023] The reinforcement grids of the reinforced soil can be wedge-shaped, with the wedge angle corresponding to the slope angle. The wedge angle can be between 60° and 90°. The reinforcement grids are in particular structural steel mats.

[0024] When forming the reinforced soil, the reinforcement grid is placed in the desired position. The suspension parts can then be arranged in the desired position, after which a geotextile can be positioned on the inside of the reinforcement grid. Alternatively, the geotextile can also be positioned on the inside of the reinforcement grid before the suspension parts are arranged. In this case, the suspension parts penetrate the geotextile. Finally, the soil material can be arranged in the area of the reinforcement grid and geotextile and compacted if necessary to form a layer of reinforced soil. A layer can have a height of 30 cm to 70 cm, for example about 40 cm or about 60 cm.

[0025] The work platform described here can be suspended in the suspension parts thus provided.

[0026] The suspension parts can be arranged in the area of the lower edge of a layer of reinforced earth, i.e. in particular less than 20 cm from the lower edge of this layer. In this case, the support parts can support the working platform on the layer of reinforced earth below.

[0027] Where appropriate, the distance between the upper edge of the top layer of reinforced soil and the stage surface, i.e. the potential fall height, is less than 200 cm.

[0028] A working platform for arrangement on an embankment surface of reinforced earth is described, wherein the embankment surface has a slope inclination between 60° and 90°, wherein the working platform comprises two consoles and a stage surface, wherein the stage surface has a working depth of at least 100 cm and wherein the stage surface is limited by a fall protection protruding at an angle from the stage surface.

[0029] The brackets each comprise a platform leg with a platform surface arranged thereon and a fastening leg. The fastening leg comprises a suspension hook for hanging the bracket in a suspension part arranged on the embankment surface, so that the suspension part is arranged in a suspension area of the suspension hook, and comprises a support part arranged remotely from the suspension hook for supporting the work platform on the surface.

[0030] A securing part which is pivotably mounted about a pivot axis is arranged on the fastening leg and which comprises a securing leg pointing in the direction of the suspension hook, wherein the securing leg closes off the suspension area in a locking position of the securing part.

[0031] If necessary, it is provided that the centre of gravity of the safety part in the locking position is below the pivot axis of the safety part when the work platform is in the operating position.

[0032] According to the invention, the securing part comprises a lifting section for engagement of a lifting device, such as a crane hook. If necessary, further attachment points for engagement of a lifting device are provided on the work platform, for example for lifting with a 4-strand chain sling.

[0033] If necessary, it is provided that the lifting section is arranged in such a way that the securing part pivots into a release position when the work platform is raised on the lifting section, so that the securing leg releases the suspension area.

[0034] Optionally, it is provided that the support part is adjustably arranged on the fastening leg and/or that the support part is T-shaped.

[0035] Optionally, it is provided that the fastening leg is arranged substantially orthogonally to the stage leg.

[0036] If necessary, it is provided that at least one locking device is provided on the securing part, which can limit or prevent pivoting of the securing part in the direction of the release position.

[0037] If appropriate, it is provided that the safety part is designed in such a way that the safety leg swings over into the suspension area when the suspension part is not arranged in the suspension area in the operating position of the work platform and thereby indicates in particular an incorrect positioning of the work platform.

[0038] If appropriate, it is provided that the stage surface comprises several surface sections, wherein the surface sections run transversely to the extension of the stage legs, and/or that a folding device, in particular a hinge, is provided for folding the fall protection and, if appropriate, the railing towards the stage surface. If appropriate, the height of the railing on which the fall protection can be arranged is less than or equal to the working depth of the stage surface.

[0039] If appropriate, it is provided that the fall protection is designed to be closed at least up to a height of 50 cm starting from the stage area. If appropriate, the fall protection forms the lower area of a railing, wherein the railing has a height of at least 100 cm.

[0040] Where appropriate, the working platform is additionally designed or functions as a protective scaffold and/or safety scaffold.

[0041] An arrangement of a work platform with the features mentioned on a slope surface of reinforced earth with a slope inclination between 60° and 90°, in particular between 65° and 80°, is also described. The slope surface can be formed by a reinforcement grid of the reinforced earth, wherein suspension parts are provided on the reinforcement grid into which the suspension hooks of the work platform are suspended.

[0042] Optionally, it is provided that the reinforced soil is formed from several layers, wherein the layers comprise a, in particular wedge-shaped, reinforcement grid, soil material and optionally a geotextile arranged between the reinforcement grid and the soil material (22).

[0043] If necessary, it is provided that a layer has a height of up to 60 cm.

[0044] Optionally, it is provided that the suspension parts comprise a suspension loop and fastening legs arranged on both sides of the suspension loop, wherein the suspension loops protrude from the surface, wherein preferably each of the fastening legs spans at least four bars of the support grid.

[0045] If necessary, it is provided that the fastening legs are arranged between the reinforcement grid and the geotextile, wherein the fastening legs are further held on the reinforcement grid by additional hooks.

[0046] If necessary, it is provided that the geotextile is arranged between the fastening legs and the reinforcement grid, whereby the suspension loop penetrates the geotextile.

[0047] If necessary, it is provided that the securing legs rest against the suspension parts, in particular against the suspension loops.

[0048] Where appropriate, it is provided that the centre of gravity of the securing parts is in the

Locking position is below the swivel axis, whereby the normal distance between the swivel axis and the suspension part is smaller than the normal distance between the center of gravity and the suspension part.

[0049] If appropriate, it is provided that the suspension parts are arranged in the uppermost layer of the reinforced earth or in the layer directly adjacent to the uppermost layer, and/or that the vertical distance between the surface of the reinforced earth and the platform surface, i.e. the fall height, is less than 200 cm. In particular, the suspension parts rest on a horizontal section of the reinforcement grid, i.e. they are arranged in the lower area of a layer.

[0050] A method is also described for using a working platform with the features described here in forming a slope surface of reinforced earth with a horizontal inclination between 60° and 90°, in particular between 65° and 80°. The method may comprise the following steps:

- Arranging the suspension parts on the slope surface,

- Attach the work platform with its hooks to the suspension parts, whereby the

Safety parts are in a release position, and - moving the safety parts into the locked position.

[0051] If necessary, it is provided that the embankment surface is formed by a reinforcement grid of reinforced earth, the reinforced earth being formed by

- Arranging the reinforcement grid,

- Arranging the suspension parts on the reinforcement grid,

- if necessary, arranging a geotextile on the reinforcement grid, and

- Filling the reinforcement grid with soil material, whereby the working platform is attached after the reinforcement grid has been filled with soil material.

[0052] If appropriate, it is provided that the method further comprises the following steps: - moving the securing parts into the release position, in particular by lifting the work platform at the lifting sections, - unhooking the hooks of the work platform from the hooking parts, - hanging the work platform with its hooks in other hooking parts, the securing parts being in the release position, and - moving the securing parts into the locking position.

[0053] If necessary, the reinforced soil can be formed in several layers, with the suspension parts then being arranged on one of these layers. If necessary, layers without suspension parts can be formed, with these layers being located above the layer on which suspension parts are arranged. If necessary, one, two, three or four layers without suspension parts are formed between a layer with suspension parts. After that, another layer with suspension parts can be arranged.

[0054] If appropriate, the method may therefore comprise the formation of several layers of reinforced earth arranged one above the other. If appropriate, the working platform is suspended from one layer to a layer above it if the height of fall between the surface of the uppermost layer and the platform surface is more than 200 cm, in particular more than 140 cm.

[0055] The work platform is repositioned in particular by lifting the work platform using a lifting section arranged on the lifting sections. If present, the locking device is released beforehand so that the securing parts can move into the release position. By lifting the work platform, the suspension hooks are released from the suspension parts so that the suspension hooks can be arranged on other suspension parts, in particular on suspension parts of an overlying layer of reinforced earth.

[0056] If necessary, after positioning the work platform, the lifting device is released from the lifting sections so that the safety parts can move into the locking position. This is particularly the case if the suspension parts are arranged in the suspension areas. If present, the locking device can then be actuated again.

[0057] After the transfer, layers of reinforced earth can be formed again if necessary, with further transfer taking place in particular when a predefined maximum fall height is reached.

[0058] Further features emerge from the patent claims, the figures and the description of the embodiments. The work platform is described in detail below using exemplary embodiments.

[0069] Unless otherwise indicated, the following features are shown in the figures: slope surface 1, console 2, platform leg 3, fastening leg 4, suspension hook 5, suspension part 6, suspension area 7, support part 8, pivot axis 9 (of the securing part 10), securing part 10, securing leg 11, locking device 12 (of the securing part 10), suspension loop 13, lifting section 14, lifting device 15, anchor point 16, platform surface 17, fastening leg 18, railing 19, reinforcement grid 20, geotextile 21, soil material 22, surface section 23 (of the platform surface 17), folding device 24, fall protection 25, layer 26, additional hook 27, height 28 (of layer 26), working depth 29, indicator section 30, connecting leg 31, supporting leg 32, fastening hole 33, surface 34, fall height 35, lattice bar 36, folding device 37, slope inclination a.

[0070] Fig. 1 shows a schematic side sectional view of a work platform according to a first embodiment. The work platform is here in an operating position. In particular, the platform surface 17 of the work platform is in a substantially horizontal position.

[0071] The work platform comprises two consoles 2, of which only one is visible in Fig. 1. The stage surface 17 is arranged on a stage leg 3 of the consoles 2 and is delimited by a fall protection 25. The fall protection 25 is closed and forms the lower area of a railing 19. The railing 19 is connected to the stage surface 17 via a folding device 24 so that it can be folded down towards the stage surface for transport.

[0072] The stage surface 17 has in this embodiment a working depth 29 of approximately

100 cm. The stage surface 17 is formed by several surface sections 23 in the form of post covering, which is arranged between the two stage legs 3.

[0073] The two brackets 2 each further 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 region and a support part 8 arranged in its lower region.

[0074] The suspension hook 5 of the two brackets 2 is each assigned a securing part 10 which is pivotably mounted about a pivot axis 9. The securing part 10 comprises a securing leg 11 which points in the direction of the suspension hook 5.

[0075] In the view of Fig. 1, the suspension hook 5 is suspended in a suspension part 6, wherein the suspension 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 approximately 80°.

[0076] The suspension part 6 is arranged in a suspension area 7 of the suspension hook 5. The securing part 10 is in a locking position in which the securing leg 11 closes the suspension area 7.

[0077] 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 explained in more detail below in connection with the description of Fig. 3.

[0078] The support part 8 is adjustably arranged on the fastening leg 4 and it supports the working platform against the embankment surface 1.

[0079] In the embodiment shown in Fig. 1, the stage leg 3 is arranged at the lower end of the fastening leg 4, i.e. in the region of the support part 8.

[0080] A further folding device 37 in the form of a hinge is arranged between the two posts that are closest to the hooks 5. This allows the outermost post to be folded away, which allows a better view of the support part 8 and better stacking when the fall protection 25 or railing 19 is folded in.

[0081] An alternative embodiment is shown in Fig. 2, in which the stage leg 3 is arranged at the upper end of the fastening leg 4, i.e. in the region of the suspension hook 5.

[0082] The second embodiment shown in Fig. 2 otherwise corresponds largely to the first embodiment and is therefore not described in detail. In contrast to the first embodiment, in the second embodiment the attachment points 16 are arranged in the area of the stage surface 17.

[0083] Fig. 3 shows a schematic detailed view of the area of the suspension hook 5 of a work platform according to an embodiment in the release position, while Fig. 4 shows this area in the locking position. Fig. 5 shows the same area, with the securing part 10 in a further position. The securing part 10 assumes this position if the suspension hook 5 is incorrectly positioned, namely if the suspension part 6 is not in the suspension area 7.

[0084] The suspension hook 5 has a suspension area 7 for receiving the suspension part 6. A securing part 10 is also provided, which is pivotably mounted about a pivot axis 9. The securing part 10 comprises a securing leg 11, which closes off the suspension area 7 in a locking position (as shown in Fig. 4). If the securing part 10 is lifted at the lifting section 14 by means of a lifting device 15, the securing part 10 is displaced into a release position (as shown in Fig. 3).

[0085] In the locking position, the center of gravity of the safety part 10 is below the pivot axis 9, so that the safety part 10 automatically pivots into the locking position when

the lifting device 15 does not lift the work platform.

[0086] In the case of the securing part 10, the horizontal distance between the center of mass 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 mass and the hook 6 is greater than the normal distance between the pivot axis 9 and the hook 6. The securing leg 11 therefore hits the hook 6. If no hook 6 were arranged in the hook area 7, the securing 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 aligned parallel to the upper area of the hook 5, so that incorrect positioning could easily be detected. This position of the securing part is shown in Fig. 5.

[0087] In order to hold the safety part 10 in the locking position, a locking device 12 is provided, which is designed as a locking bolt that is guided through corresponding holes in the safety part 10. This prevents the safety part 10 from being accidentally moved after the work platform has been placed.

[0088] Fig. 6 shows a schematic view of a support part 8 according to an embodiment. This support part 8 is T-shaped and has a connecting leg 31 for connection to the fastening leg 4 and a supporting leg 32 for support on the slope surface 1. Several fastening holes 33 are provided on the connecting leg 31 in order to be able to adjust the position of the support part 8.

[0089] Fig. 7 shows a schematic side sectional view of an arrangement of a work platform on reinforced earth according to an embodiment. The reinforced earth comprises three layers 26, each having a height 28 of approximately 60 cm. Each layer 26 is formed from a wedge-shaped reinforcement grid 20, compacted soil material 22 and a geotextile 21 arranged between the reinforcement grid 20 and the soil material 22.

[0090] The outer side of the reinforcement grid 20 forms the slope surface 1, which in this embodiment has a slope inclination a of approximately 65°.

[0091] In Fig. 7, suspension parts 6 are arranged in the lower area of the uppermost layer. The positioning of the suspension parts 6 on the reinforced soil is shown in detail in Fig. 7.

[0092] A working platform with its hooks 5 is suspended in the suspension parts 6, as has already been described in detail in connection with Fig. 1. The support parts 8 support the working platform against the embankment surface 1, wherein the support parts 8 are supported on the layer 26 which is directly below the layer 26 on which the suspension parts 6 are arranged.

[0093] The vertical distance between the surface 34 of the reinforced earth and the stage surface 17, i.e. the fall height 35, is approximately 85 cm in this view.

[0094] Fig. 8 shows a schematic detailed view of the suspension hook 6 of the arrangement from Fig. 7. The suspension hook 6 comprises two fastening legs 18, each of which spans four bars 36 of the reinforcement grid 20. Between the fastening legs 18, a suspension loop 13 is arranged, which projects out from the embankment surface 1 and into which the suspension hooks 5 of the work platform can be hooked.

[0095] The geotextile 21 is arranged between the fastening legs 18 and the reinforcement grid 20. For this purpose, it is necessary that the suspension loop 13 penetrates the geotextile 21.

[0096] Fig. 9 shows a further schematic detailed view of a suspension hook 6 which is arranged on a reinforcement grid 20. In contrast to Fig. 8, the fastening legs 18 are arranged here between the geotextile 21 and the reinforcement grid 20. For stabilization, additional hooks 27 are provided which run transversely to the fastening legs 18.
