Definitions

  • the invention relates to a clamp fitting for scaffolding according to the preamble of protection claim 1.
  • Such scaffolding is available as a mobile or as a standing scaffold and consists essentially of a lower boarding level, which is referred to as an access platform, which is arranged horizontally and from which vertical scaffolding frames extend upwards, which may be connected by diagonal struts, with further work platforms attached to the top of the scaffolding frame.
  • the invention has for its object to improve the attachment of the horizontal stages to the horizontal crossbeams of the scaffolding by means of clamp fittings so that there is a virtually play-free connection.
  • the invention is characterized by the technical teaching of claim 1.
  • An essential feature of the present invention is the clamp fitting, which offers a practically positive and non-positive connection between the respective platform and the associated cross member.
  • crossbeam is polygonal, e.g. as a square, rectangular, roof profile, oval profile or the like and it is ensured that the clamping fitting is adapted in its inner circumference to the outer profile of the cross member, so that the clamping fitting encompasses this cross member in a form-fitting manner and can be clamped to it.
  • the clamp fitting is designed in its inner profile in such a way that it positively encloses the profile of the crossmember to be enclosed and that at least one locking part is also present, which can be pivoted with a corresponding screw on one side of the crossmember that, in addition to the positive engagement mentioned, there is still a frictional engagement, ie the clamp fitting on the crossbar tensions.
  • the clamp fitting is easy to open and close, which has the advantage that when the clamp fitting is opened, the entire access platform can be moved in relation to the fixed crossmember and, moreover, that with the crossmember connected scaffolding frames.
  • the clamp fitting is not only used for fastening the respective platforms (entry platform and work platforms), but also on the undersides of the respective scaffolding frames, which are equipped with the same clamp fittings.
  • the respective clamp fittings When the respective clamp fittings are opened, the scaffold frames and the platforms can be moved horizontally along the crossbars.
  • This shift can be adapted to the progress of work without the need to partially dismantle the entire scaffolding in order to achieve a gradual shift (repositioning), as in the prior art.
  • the mobile scaffold 1 essentially consists of a base platform 2, which in turn consists of horizontal crossbeams 5 which form a mutual distance, only the foremost crossbeam 5 being visible in FIGS. 1 and 2.
  • the two trusses 5 are connected to one another via a so-called access platform 3.
  • An adjustment foot 6 is attached to each cross member 5 and can have rollers 7 that can be locked on its underside.
  • the scaffold frame 4 and the access platform 3 can be moved continuously along the cross members 5 in the direction of the arrow 9.
  • the clamp fittings 8 according to the invention are released; the mentioned parts are then shifted according to FIG. 2 and the clamping fittings 8 are then tightened again.
  • the access platform 3 with the clamp fittings 8 attached to it is first attached to one side of the crossmember 5 and fastened, the clamp fittings 8 located here on the opposite side remaining free.
  • the opposite traverse is then moved up with the adjustment feet 6 attached to it and the access platform 3 is raised and the clamping fittings 8 are placed around the crossbar 5 and tightened in the open state, so that the state according to FIG. 3 results.
  • the work scaffold can be further built by a single person, for example after the attachment of the scaffold frames 4, which are also fastened to the cross members 5 with the clamping fittings 8, further diagonal struts 11 are fastened to the scaffold frames 4.
  • the clamp fitting 8 is fastened to the end face of the respective entry platform 3 with the aid of tabs 13.
  • the tabs 13 are welded or screwed or riveted.
  • the clamp fitting essentially consists of the tabs 13, which are connected in one piece with the material or via corresponding connecting points to the vertical leg 14 of the clamp fitting.
  • the leg 14 is connected to a horizontal leg 15, on the outer, free end of which a pivot pin 17 is fastened, on which a locking part 16 is pivotally arranged.
  • a slot 20 is arranged on the underside of the closing part 16.
  • a further pivot pin 18 is arranged on the leg 14, on which the pivot bearing for a clamping screw 22 is formed. This extends below the cross member 5 and is provided with a ring nut 19.
  • the closing part 16 is thus rotated about the pivot pin 17 until it bears against the outside of the cross member 5.
  • the clamping screw 22 is then pivoted about the pivot pin 18 until the screw enters the slot 20 in the leg 16, and the ring nut 19 is then tightened so that the locking part 16 clamps against the outside of the cross member 5 and at the same time the leg 14 generates the corresponding counter pressure.
  • the cross member 5 which is designed as a square profile, is connected to the adjustable feet 6 with vertical round parts 12, each round part being designed as a sleeve, through which a spindle 10 extends.
  • the spindle 10 is firmly connected to a roller bearing 23.
  • a spindle nut 21 is rotatably seated on the spindle 10, so that the height of the roller bearing 23 and thus the roller 7 can be adjusted continuously.
