Definitions

  • the invention relates to a scaffolding according to the preamble of claim 1.
  • the work scaffolding consists of horizontal, mutually spaced trusses, which are connected to each other by an entry platform. At the end of each traverse an adjustable foot is arranged in a manner known per se.
  • Vertical scaffolding frames are arranged on the trusses, which are connected by diagonal struts, the scaffolding frames being connected to horizontal work platforms, which work platforms are arranged parallel to the lowest entry platform lying on the crossmember.
  • the telescopic design of the trusses has the disadvantage that the manufacture and maintenance is relatively complex.
  • the telescopic struts tend to get dirty and seize, so that it is not easily possible to change the working width.
  • the manufacturing effort for the entire scaffolding is extremely high, because you only have to provide for certain, relatively few scaffolding the need to change the stand width.
  • the crossheads can be telescoped regardless of the height, which is associated with the high manufacturing costs mentioned.
  • the invention is therefore based on the object of developing a work scaffold with a variable standing width so that a simple and reliable change in the standing width is provided with significantly lower manufacturing costs.
  • the invention is characterized by the technical teaching of claim 1.
  • crossbeams are not designed to be telescopic, but that with the aid of a coupling fitting at the free end of each crossbeam an extension arm can be attached which is equipped with the adjustable foot.
  • a work scaffold with a relatively small standing width is therefore proposed, the trusses themselves cannot be extended.
  • the stand width must also be increased accordingly.
  • the adjustable foot is simply removed from one end of the respective traverse, and a coupling fitting is attached at this point, which is connected to an additional extension arm.
  • the extension arm corresponds to the extension of the traverse and carries at its free, outer end again a holder (round part) for holding the adjustable foot.
  • an extension arm is simply added, which is coupled to the crossbar with an associated coupling fitting and which in turn has the receptacle for the adjustable foot at its outer end.
  • a clamping fitting is used as the coupling fitting, which is constructed essentially like a scaffolding coupling, in order to fasten the extension arm to the tubular part of the crossmember, in order to create a first of two existing fastenings.
  • the second attachment of the extension arm is that either the tubular part of the traverse is gripped with an eyelet of the extension arm, thereby creating a dimensionally stable holder.
  • a beveled hook part is proposed, which engages around the crossbeam from below.
  • the extension arm in the working position the extension arm forms the continuation of the longitudinal axis of the cross member, in order to avoid that the extension arm inadvertently extends to the cross member in the working position.
  • the extension arm can be pivoted inwards and outwards, for example in order to be able to drive through the work scaffold through narrow passages and the like.
  • the adjusting foot In the first-mentioned solution, where the extension arm is formed with a lower eyelet which encompasses the tubular part of the traverse, the adjusting foot must first be removed from this tubular part when the extension arm is being installed, so that it can then be mounted at the end of the extension arm.
  • the crosshead must be supported during this time.
  • the second solution provides that the extension arm can be attached to this tube part when the adjustment foot is located in the tube part.
  • the adjustable foot can then remain at this point and the extension arm then carries at its outer end a further adjustable foot, so that there is additional support via two spaced-apart adjustable feet.
  • the standing width 10 is to be increased to the standing width 11.
  • the work scaffold consists, in a manner known per se, of horizontal crossbeams 3 which are at a mutual distance from one another and which (not shown in the drawing) are connected to one another by corresponding horizontal platforms.
  • At least one scaffold frame 2 is attached to each crossmember 3 with the aid of associated clamp fittings 4.
  • an adjustable foot 5 is arranged, which is held adjustably in a tubular part 6 connected to the cross member 3.
  • the work scaffold 1 now has the right adjustable foot 5 at the stand width 10.
  • an extension arm 8 is mounted at the location of the right adjusting foot 5 with the aid of a coupling fitting 7, which in turn has the tubular part 6 on its outside, on which an adjusting foot 5 'can be mounted.
  • either the right adjustment foot 5 can remain in place, or it can be removed (shown in dashed lines in FIG. 1) and mounted at the location of the adjustment foot 5 '.
  • the standing width 10 has been increased to the standing width 11 in a simple manner.
  • the work scaffold 1 is shown with an increased standing width 11.
  • the assembly of the extension arm 8 on the crossmember takes place in that at the free end of the extension arm 8 an eyelet 12 is arranged at the bottom, which comprises the lower part of the tubular part 6, so that in the assembled state the central axis 13 through the tubular part 6 of the central axis 13 of the Coupling fitting 7 corresponds.
  • the scaffold bracket 22 forming part of the coupling fitting 7 is opened.
  • the scaffold bracket 22 essentially exists from a locking part 15 which is pivotally attached to a fixed holder 21 via a pivot pin 17.
  • a hammer head screw 18 engages, onto which a ring nut 14 is screwed.
  • FIGs 7 and 8 show the relationships according to Figures 3 to 6 in the assembled state. It can be seen here that the eyelet 12 encompasses the lower part of the tubular part 6, while the upper part of the tubular part is enclosed by the scaffold tip 22.
  • the tubular part 6 then grips the spindle 9 of the adjustable foot 5, the height of the adjustable foot being adjustable by turning the spindle nut 16.
  • FIGS. 9-14 show a second embodiment of a coupling fitting.
  • the coupling fitting 23 in turn has the previously described scaffold bracket 22, the encirclement of the lower part of the tubular part 6 now being solved differently.
  • a connecting part 20 is provided, on the free end of which a hook part 19 is formed.
  • This hook part 19 has a cranked hook which at least partially encompasses the rectangular profile of the cross member 3 according to FIG.
  • the hook part thus forms an upwardly open receptacle 24, which engages in a form-fitting manner on the underside of the cross member 3, and the hook of the hook part which is bent upward attaches itself the side faces of the crossbar 3.
