Description

[0001] The invention relates to a fall protection device, in particular for the assembly of a commercial hall, such as a steel hall, with walls and a roof. background

[0002] The invention relates in particular to the entire fall protection device, with aluminum plate and fleece, support rod, center console, steel bracket, tube and eyelets and screws for mounting the fall protection device, preferably a roof edge fall protection device.

[0003] It is particularly suitable for use in the construction of an industrial hall or other commercial hall, e.g. a steel hall.

[0004] When constructing such halls, vertical steel supports are installed first, followed by the walls, and finally the roof. During construction, it is necessary to provide fall protection for the installers. State of the art

[0005] With conventional fall protection systems, it's not possible to install fall protection after the walls have been installed. This is because the conventional fall protection systems are attached to the steel supports, which are no longer accessible from the outside once the walls are in place.

[0006] In halls with a roof overhang, it is also almost impossible to assemble the walls with a crane, as the crane's "block" and "chain" cannot reach the desired position because the roof overhang is in the way. Task and solution of the invention

[0007] Object of the invention: The above-mentioned disadvantages of the prior art are to be avoided.

[0008] This object is achieved according to the invention in a fall protection device of the type mentioned at the outset in that the fall protection device comprises a central console (19) for supporting and carrying a fall protection net and a holding bracket (16, 17) for connecting the central console (19) to a wall (18) of the hall, and that the central console (19) and the holding bracket (16, 17) are separable from one another.

[0009] This problem is solved with the fall protection device according to the invention, since this fall protection device is not mounted on steel supports, but on a steel profile above the wall.

[0010] This makes it easier to install the wall panels.

[0011] The fall protection system according to the invention is specifically designed for the safe and efficient installation of roofs and walls in hall structures with sandwich panels. The key advantage of this design is that it allows the wall panels to be installed first, before the roof is installed. This simplifies the installation of the wall panels and allows even heavy walls to be installed by crane without the roof structure (roof overhang) getting in the way. This fall protection system reduces installation times and the need for additional temporary safety measures.

[0012] Support rod with aluminum plate: An aluminum plate is attached to a steel tube with a screw; its angle can be adjusted through a slotted hole. A fleece is glued to this plate to prevent scratching the exterior wall. Additionally, the angle of the support rod can be adjusted using a toothed system. Horizontal support is provided by the plate resting against the exterior wall.

[0013] Center console: The center console contains the counterpart of the support rod's interlocking system. Above the interlocking system is a welded tube; the rod with eyelets is inserted into this tube for attaching nets. Next to the tube is a tab with a hole; this is used to attach the steel bracket.

[0014] Steel bracket: The steel bracket is attached to the center console with a screw, washer, and nut. It has two holes on the opposite side. These holes are used to attach it to a U-profile inside the hall with two self-tapping screws. This bracket is subjected to tensile stress and prevents the support rod from falling down.

[0015] The entire fall protection system is protected from external influences by hot-dip galvanizing to prevent corrosion. Advantages of the invention

[0016] Among other things, the following benefits are achieved: Once the thermal roof and thermal wall are installed, the fall protection system according to the invention can be removed by loosening three screws without causing any damage to the fall protection system or the hall.

[0017] Thanks to the innovative interlocking of the center console and support rod, the fall protection system can be adjusted to any roof pitch. This adjustment can be made on-site, saving time and ensuring very easy installation.

[0018] The toothing in the center console allows for adjustment of both the angle of the support rod and the angle to the support tube 1. Furthermore, the support tube is secured to the center console with a screw. Because the center console and steel bracket are connected by only one screw (thread in the steel bracket), the entire fall protection system can be removed from the roof and wall after installation without damaging any components.

[0019] The support rod has a counterpart to the toothing on the center console. Thanks to the welded-in tube 7 (center section), it is very robust and can absorb high forces.

[0020] The aluminum plate 12 has a radial slot 22 in the welded tab 13 and a hole 23 below it. This radial slot 22 allows the aluminum plate 12 (support foot) to be adjusted at a 60° angle and adapted to the wall 18. A 250 mm diameter fleece is glued to the underside to prevent damage to the surface of the wall panels.

[0021] Most importantly, the detachable fall protection system allows wall panels to be installed before the roof is installed.

[0022] In developing the invention, the inventor has overcome the following technical difficulties in a non-obvious manner.

[0023] The biggest challenge in the design was creating a way to remove the fall protection system without leaving any residue after the roof and wall were installed. By separating the steel bracket (support brackets 16, 17) and the center console, the front section of the fall protection system can now be removed forward and the steel bracket removed from the inside.

[0024] Another problem was that the steel bracket (originally made of flat steel t = 5 mm) was not stable enough. The inventor replaced it with a flat steel t = 10 mm.

[0025] Advantageous embodiments of the invention are set out in the subclaims.

[0026] It is proposed that - that the center console (19) and the retaining bracket (16, 17) are screwed together, - that the fall protection device has a support rod (2) and that the central console (19) and the support rod (2) have teeth which engage with each other and with which the angle of inclination of the support rod (2) to the central console (19) can be adjusted. Examples of implementation

[0027] Several exemplary embodiments of the invention are described in more detail below with reference to the drawings. In all drawings, the same reference numerals have the same meaning and are therefore explained only once if necessary.

[0028] It shows Fig. 1 a first embodiment of the fall protection device according to the invention in perspective view, before assembly, in a variant for the eaves side as variant 1, Fig. 2 the fall protection according to Fig. 1 in perspective view, after assembly, Fig. 3 fall protection according to Fig. 1 in longitudinal section or side view, Fig. 4 fall protection according to Fig. 1 in longitudinal section or in side view, but as a second embodiment of the fall protection device according to the invention in a variant for the gable side as variant 2, Fig. 5 the center console of the fall protection devices according to the Fig. 1 to 4, in three different views, Fig. 6 the support rod of the fall protection devices according to Fig. 1 to 4, in two different views, Fig. 7 the base of the fall protection devices according to Fig. 1 to 4, in three different views, with aluminum plate and tab, Fig. 8 the steel bracket (holding bracket) for the variant on the eaves side, in two different views, and Fig. 9 the steel bracket (holding bracket) for the variant on the gable side, in two different views. Structure of the fall protection device according to the invention

[0029] The Fig. 1 to 3 show a first embodiment of the fall protection device according to the invention in perspective view, in a variant for the eaves side (variant 1), before assembly ( Fig. 1), after assembly ( Fig. 2) and in longitudinal section or in side view ( Fig. 3).

[0030] The fall protection consists of 12 elements, namely • a support rod 2, consisting of 3 parts, namely (see Fig. 6) ◯ serrated sheet 6 ◯ Round tube 7 ◯ Mounting bracket 20 • a toothed center console 19, consisting of 5 parts, some of which are welded together, namely (see Fig. 5) ◯ Pipe holder 8 ◯ toothed tab 9 ◯ Angle 10 ◯ Screw 3 ◯ Mother(s) 4 • a plate 12 with a welded tab 13 and a hook-like retaining bracket 16, 17.

[0031] Using the retaining bracket 16, the fall protection device can be mounted on the eaves side of the hall.

[0032] In a corresponding way, Fig. Figure 4 shows a second embodiment of the fall protection device according to the invention in perspective, in a variant for the gable side (variant 2) in longitudinal section and in side view. The retaining bracket 17, with which the fall protection device can be mounted on the gable side of the hall, is different.

[0033] Fig. 5 shows the so-called center console 19 in three views, namely in a side view, from behind and from above, with • a pipe holder 8 for a holding pipe 1 for a fall protection net • a toothed tab 9 • an angle 10.

[0034] The parts of the center console are welded together.

[0035] Fig. Figure 6 shows the support rod 2 in two views, namely a top view and a side view, with • a toothed sheet 6 • a round tube 7 and • two fastening tabs 20.

[0036] Support rod 2 consists primarily of a round tube (RR ø48.3 × 5.0 - 282 mm) and supports the entire fall protection system downwards against the wall. It is connected to the support foot (plate 12 and bracket 13) and, on the other side, to the bracket 8 for tube 1.

[0037] Part 9 is a flame-cut part (a steel molded part cut from thick steel plates using oxyacetylene cutting) and is the counterpart to Part 6, which is also a flame-cut part. These two "rows of teeth" interlock and ensure the ability to adapt the entire fall protection system to the specific wall and roof slope.

[0038] The two different brackets for the gable side (part 17) and the bracket for the eaves side (part 16), see Fig. 8 and Fig. 9, can be exchanged depending on the application and screwed onto the basic concept of the fall protection, depending on how many brackets are needed per side. Operation of the fall protection device according to the invention

[0039] The operation of the fall protection device according to the invention is explained in detail below: Step 1: Screw the corresponding bracket 16, 17 to the center console 19: There is a hole 5 in bracket 10 of the center console 19. Through this hole, the center console 19 and the corresponding retaining bracket 16, 17 are connected with a screw 3, depending on whether the fall protection is to be used on the gable or eaves side. Step 2: Slightly loosen the two screws 21 in the base 11 (plate 12), but do not loosen them completely, just so that the plate 12 and the tab 13 can be moved relative to the support rod 2. Step 3: Attach the complete fall protection system (without support tube 1) to the retaining bracket 16, 17: The base 11, since it is freely movable, will now align itself against the wall 18. Once the base 11 is against the wall 18, retighten the two screws 21 that were loosened in step 2. Step 4: The retaining bracket 16, 17 has two holes positioned one above the other. These are attached to the hall using self-tapping screws, either to the verge angle 15 or to the eave purlin 14. Step 5: The last step is to insert the holding tube 1 into the pipe holder 8 provided and to secure it with a screw 3 provided through the holes in the pipe holder 8 and in the holding tube 1.

[0040] Thanks to the interlocking system in the center console, the product according to the invention can achieve an inclination angle of 0° to 10° to the vertical for any roof pitch angle, according to DGUV 301-002, December 2017 (3.2.2). Therefore, for the fall protection system according to the invention, only 1 / 3 of the load may be applied in the static design. For larger angles, namely 10° to 45° angle of the edge tube, three times the load would have to be applied. This angle can be adjusted via the center console.

[0041] In addition, the fall protection system according to the invention works with different panel thicknesses of both roof and wall.

[0042] According to the German Social Accident Insurance (DGUV), the edge safety net must be 1.5 meters high from the roof edge. This is very well implemented in the inventive solution, as the bracket is suspended directly below the roof. This eliminates the need for excessively long support poles.
