Description

The invention relates to a side protection module for a system frame structure comprising a first post, a second post, an upper member and a lower member.

Such side protection modules are used to prevent workers from falling during assembly work on system frameworks. In particular, it is necessary to have side protection prior to work in a new scaffolding level by means of leading side protection modules.

Known systems of separate individual elements are used as temporary protection for the erection and dismantling of the scaffolding. Railing elements running ahead are installed during assembly and replaced by other railing elements for regular operation.

The prior art also shows systems of rigid side guard rails that can be mounted from a secure position and that can remain permanently in the system frame structure.

The disadvantage here is that the side guard rails are unwieldy to handle and take up a large volume when they are transported.

The invention is therefore based on the object of creating a leading side protection which can be handled more practically.

This object is achieved by the characterizing features of the independent claims. The subclaims reflect advantageous and expedient developments.

The invention relates to a side protection module for a system frame structure comprising a first post, a second post, an upper beam and a lower beam, characterized in that the upper beam can be pivoted by means of a first upper beam joint and a second upper beam joint and the lower beam can be pivoted by means of a first lower beam joint and a second lower beam joint attached to the first handle and the second handle and detached using a special tool.

The formation of the side protection module by means of articulated upper and lower bars makes it possible to move the side protection module into an assembly position, whereby a worker can use an improved radius of movement during the assembly process.

In a preferred embodiment it is provided that the upper bar by means of joints and the lower bar by means of joints pivotably in a plane between the first post and the second post are arranged, in particular fastened, and the joints are horizontally offset from one another.

The degree of freedom between the spars and the stems is restricted in this version, which enables easier handling of the side protection module. In addition, the side protection module can be folded up to save space. If the side protection module is installed on a system frame scaffolding, the bars can be hung down in parallel by loosening the joints, making the scaffolding level freely accessible.

Furthermore, it is provided that a longitudinal extension of the first stem and / or a longitudinal extension of the second stem is greater, in particular at least a third longer, is preferred at least twice as long as the distance between the upper bar and the lower bar, preferably in the installed state, and / or the distance between the first upper bar hinge and the first lower bar hinge and the distance between the second upper bar hinge and the second lower bar hinge.

This ensures the necessary stability, which also enables flexible use in low or higher building areas.

Another embodiment provides that the first handle and the second handle are jointly connected to the upper bar and the lower bar in the form of a parallelogram.

This gives the side protection module a defined shape with restricted degrees of freedom of movement. Elongated shapes with narrow dimensions as well as right-angled shapes with a large area are possible. The side protection module can be swiveled together in a controlled manner in order to store it compactly for transport purposes. In addition, this enables the side protection modules to be passed on over a greater distance. Tilting for installation and extensive protection of the levels are thereby possible.

In a further preferred embodiment it is provided that the side protection module comprises a holding means or securing means, in particular a locking mechanism or a band or a chain on at least one of the joints, which in particular in a pivoted and / or collapsed state preferably the upper rail and the lower rail to one another releasably fixed.

In this way, compact and safe storage and transport are possible without the available degrees of freedom of the joints being able to jam or catch the side protection modules with one another, for example on a transport pallet.

Another embodiment of the side protection module provides that a holding means or securing means fixes the bars to one another, e.g. the upper bar with the lower bar to one another in a detachable manner. In this way, the side protection module can be easily and compactly transported in the collapsed state and handled on the frame without having to handle a bulky, possibly inherently non-dimensionally stable object. A securing means is provided, which is designed, for example, as a mouth-shaped securing means, preferably with a locking means for locking the securing means in the collapsed state.

It is also provided that the upper beam and the lower beam are rigid.

The stability of the bars ensures simplified handling and increased safety. Furthermore, by varying the bars, greater flexibility can be used when using the side protection modules.

It is also provided that the upper spar and / or the lower spar are shortened compared to a scaffolding bay, in particular the bar length is made smaller by 50 cm compared to the scaffolding bay. The dimensions of a scaffolding bay are in particular formed by the distance along the longitudinal direction of a walking floor between the two vertical styles.

This increases the flexibility and compatibility of the side protection module when used with existing systems.

In a preferred embodiment it is provided that on the first post and / or on the second post, one arm protruding from a plane defined by the post and the spars is formed.

The outriggers ensure that the bars are offset in the direction of the walking floor, which enables greater safety thanks to the side protection module.

An expedient development of the side protection module provides that a receptacle forming a support is attached to the first arm and a receptacle forming a counter bearing for a vertical post is attached to the second arm. In particular, at least one, preferably both, receptacles is fork-shaped.

The securing on the vertical post is improved by a corresponding receptacle formation, in particular a fork-shaped formation engages around the vertical post in a form-fitting manner.

It is further provided that the first stick has at least one first support arm and / or the second stick has at least one second support arm.

The support brackets ensure increased stability of the side protection module within a system frame structure and, in conjunction with a vertical frame, can prevent the side protection modules from being removed at a later date.

In a preferred embodiment it is provided that the first handle comprises a double-cranked first suspension arm and the second handle has a single-cranked second suspension arm.

The suspension brackets each form a bearing point on a module stand or vertical frame and enable the side protection modules to be securely fixed to the covering-bearing components of the scaffolding systems, preferably the decking traverses of the vertical frames, with the first suspension bracket allowing the side protection module to tilt due to the double cranking in order to attach the second To enable suspension arm on a second module carrier.

Furthermore, it is provided that the joints are at least partially encased, in particular covered by means of a cover, preferably a tubular cover, as a clamping protection.

This prevents fingers from being trapped and the function being restricted by dirt.

The invention also provides a collapsible system frame scaffolding segment, which comprises at least two module stands or vertical frames, at least one walking floor, and at least one side protection module, the side protection module comprising a first post, a second post, an upper bar and a lower bar, the upper bar by means of a first upper rail joint and a second upper rail joint and the lower rail by means of a first lower rail joint and a second lower rail joint are pivotally attached between the first handle and the second handle, wherein the Side protection module is designed according to the embodiments set out above.

The use of a leading side protection module according to the invention on a separable system frame scaffolding segment facilitates both assembly and dismantling and always gives the worker protection against falling as soon as he has to step onto a new level when assembling the scaffolding.

Furthermore, it is provided that a receptacle forming a support of a first side protection module in combination with a receptacle forming a counter bearing of a second side protection module in combination with a vertical post of a module stand or the frame post of a vertical frame form a half-shell bearing point in a form-fitting manner. The receptacle forming a support of a first side protection module in combination with the receptacle forming a counter bearing of a second side protection module in combination with a vertical post of a module stand or vertical frame form a detachable, in the assembled state self-locking, in particular engaging behind and / or overlapping, locking.

This prevents unintentional detachment of individual elements during installation and enables quick connection to the assembly or dismantling of the system frame frame segment with the side protection module.

Figure 1 shows a side protection module 1 for a system framework. This side protection module 1 comprises a first handle 3, a second handle 4, an upper beam 5 and a lower beam 6. The upper beam 5 is by means of a first upper beam joint 7a and a second upper beam joint 7b and the lower beam 6 by means of a first lower beam joint 8a and a second lower beam joint 8b pivotable in one plane, fastened between the first handle 3 and the second handle 4. A longitudinal extension 9 of the first stem 3 and / or a longitudinal extension 10 of the second stem 4 is greater than the distance 11 between the upper spar 5 and the lower spar 6. In particular, the longitudinal extension 9 and / or 10 is at least a third longer, preferably at least twice as long. This is preferably the case when installed. In particular, the longitudinal extent 9 and / or 10 can be greater than the distance 11 between the first upper rail joint 7a and the first lower rail joint 8a and the distance 11 between the second upper rail joint 7b and the second lower rail joint 8b. The first handle 3 and the second handle 4 are connected together with the upper beam 5 and the lower beam 6 in the form of a parallelogram. On the first handle 3 and / or on the second handle 4, a respective arm 12a, 12b protruding from a plane defined by the handles 3, 4 and the bars 5, 6 is formed. A mounting hinge 13a, which forms a pivot point for pivoting, is attached to the first arm 12a, and an assembly hinge 13b, which forms an assembly counter-hinge, for a vertical post 14 is attached to the second arm 12b. The receptacles 13a, 13b are fork-shaped. The first arm 3 has at least one first support arm 15a and / or the second arm 4 has at least one second support arm 15b. The first handle 3 comprises a first double cranked Suspension arm 16. The second arm 4 has a second suspension arm 17 that is simply cranked. In sync with Figure 2 it can be seen that the suspension arms 16, 17 are a counter bearing to the in Figure 2 Form cross members 29 shown.

Figure 2 shows a collapsible system frame framework segment 18 standing on a plane N 27. This comprises a first module stand 25 or vertical frame and a second module stand 26 or vertical frame. The module uprights or vertical frames 19 comprise vertical posts 14 and carry a walking floor 20 to form a level N1 28. In connection with the side protection module (1) according to the invention, the level N1 28 can be secured in advance. In the synopsis with Figure 1 it can be seen that traverses 29 are a support to the in Figure 1 Form hanging arm 16 and 17 shown.

Figure 3 shows an installation of a side protection module 1 according to the invention on a system frame structure standing on level N 27. A first side protection module 21a is already attached in level N2 30 and a second protection module 21b is also installed. First, starting from a level N1 28, a first post 3 is installed by tilting the side protection module 21b just below the level N2 30 on a module stand 19 or vertical frame, in that the first suspension arm 16 is suspended from the cross member 29. The side protection module 1 is then tilted up into a plane N2 30 in order to hang a second post 4 in a further module stand 19 or vertical frame. Slipping out of the first post 3 is prevented by a loose lock 23, which is prevented by a mounting hinge 13a and a mounting counter-hinge 13b of a side protection module 21a already in the scaffolding, as well as the vertical post 14 encompassed by a fork-shaped receptacle.

Figure 4 shows a schematic top view of a vertical post 14 with two side protection modules 1 installed on it, each on the right and left. A second post 4 of a first side protection module 21a installed on the vertical post 4 can be seen (in FIG Figure 3 shown in full) and a first post 3 of a second side protection module 21b (in Figure 3 shown completely) with a second arm 12b of the first side protection module 21a and a first arm 12a of a second side protection module 21b. The walking floors 20 are installed on the traverse 29. A first suspension arm 16 and a second suspension arm 17 (not visible) are suspended from the vertical post 14. The first arm 12a of a second side protection module engages the vertical post 14 by means of a fork-shaped receptacle 13a and prevents slipping out during the installation of the side protection module 21b. The outriggers 12a and 12b ensure a reduced distance between the walking floors 20 and the bars, which prevents slipping through between walking floors and bars.

Figure 5 shows a perspective view of a total of four installed side protection modules 1 on two module stands 19 or vertical frames combined one above the other. A first stick 3 with a first arm 12a, a first upper beam joint 7a, as well as a first lower beam joint 8a and a first support bracket 15a can be seen twice. In addition, there is a second arm 4 with a second arm 12b, a second upper beam joint 7b, as well as a second lower beam joint 8b and a second support bracket 15b. Installed walkways 20 can be seen on a traverse 29, which form the levels secured by the side protection modules 1.

Figure 6 shows a representation of the Figure 5 excerpts in plan view. You can see part of a system frame structure formed from a first side protection module 21a and a second side protection module 21b, installed on a module frame 19 or vertical frame with walkways 20. The following is shown in detail: a first post 3 with a first upper beam joint 7a, a first lower beam joint 8a , a first support bracket 15a, a first bracket 12a, a first suspension bracket 16 and a receptacle 13a. In addition, a second handle 4 with a second upper beam joint 7b, a second lower beam joint 8b, a second support bracket 12b, a second hanging bracket 17 and a receptacle 13b can be seen. This is installed on a vertical post 14. The receptacles 13a and 13b form the half-shell pivot point 22 and a loose lock 23 Pivot point 22 is tilted to the right in order to hang the second handle 4 on the left by means of the second hanging arm 17. The mounting joints 13a and 13b prevent the elements from being accidentally detached from one another. It can also be seen that the horizontal offset of the joints 7a and 8a enables the joints 7b and 8b on a side protection module to be released by means of a special tool, and the bars can be hung down in parallel. This ensures that the level secured by this side protection module can be made freely accessible.

Figure 7 shows schematically a detailed view of the reaching under of a support arm 15a on a tilting pin 24 of a vertical post 14. This prevents an upper member 5 attached to a first post 3 by means of a first upper member joint 7a from being pulled inward in the direction of the walking levels.

Figure 8 shows a schematic representation of a side protection module 1 in the collapsed state, with a holding means or securing means 31, for example, on the first upper rail joint 7a, detachably fixing the upper rail 5 with the lower rail 6 in that the securing means 31, which is mouth-shaped in this exemplary embodiment, engages the lower rail 5 and clicks into place. Unfolding of the side protection module 1 can thus be prevented, thereby enabling space-saving storage or simpler transport.
