Definitions

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

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • joints are at least partially encased, in particular covered by means of a cover, preferably a tubular cover, as a clamping protection.
  • 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.
  • leading side protection module 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.
  • 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.
  • a side protection module is also provided which, in cooperation with a vertical post (14), prevents the side protection module (1) from being uninstalled, in particular blocked by means of a vertical post (14), in particular prevented by a stop on a vertical post (14).

  • 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.
