Definitions

  • the invention relates to a scaffold, in particular facade scaffolding according to the preamble of claim 1.
  • Such facade scaffolds are e.g. from DE 196 33 091 A1 known and generally serve in front of the facade of a building to be built, e.g. Plastering or painting work. Stabilization of the scaffold against horizontal displacements Diagonal supports usually extend from one Place directly above a cross strut to one Place the adjacent vertical support, which is slightly is located below the cross strut above. The Diagonal supports must be attached to the vertical supports in this way that both tensile and compressive forces from the vertical supports can be exercised on the diagonal supports.
  • the disadvantage of the known scaffolding is that the Diagonal supports with torsional moments on the load Exercise vertical supports and that special components on the Vertical supports must be attached to the diagonal supports to be able to attach.
  • a lattice lightweight structure which consists of tubular vertical and horizontal support elements and arranged in between Diagonal struts exist.
  • the vertical and horizontal support elements by means of mountable node connectors connected to the vertical and horizontal support elements form a positive and non-positive connection, the node connector each are divided into two half-shells, which hold the vertical support elements reach around and by means of projections in corresponding Engage holes in the vertical support elements in a form-fitting manner, and the knot connectors continue to form connecting pins on which the horizontal support elements be pushed on and held firmly.
  • US-A-2435171 is a scaffold with vertical, horizontal and diagonal supports described in which pairs of vertical sleeves on the vertical supports are welded to the bent ends of the diagonal supports to record.
  • US-A-1552333 shows vertical, horizontal and diagonal supports showing scaffolding, in which in the walls of the vertical supports perpendicular to that defined by the vertical and diagonal supports Plane-extending holes are provided in which the bent Ends or fastening bolts arranged for diagonal and horizontal supports are.
  • US-A-3330583 discloses a safety latch with which Support tubes attached to vertical and apertured rails can be.
  • a shelf is already known from US-A-4 379 430, in which between some of the vertical supports each have two halves Diagonal supports are arranged in the middle by screws are connected to one another and have hooks at their ends which with the diagonal support halves pivoted into an insertion position into vertical Slots of the assigned vertical supports introduced and through Swiveling the diagonal support halves into the final diagonal position with regard to tensile and compressive forces can be determined on what then a screw connection in the middle of all four diagonal support halves is done to form two intersecting diagonal supports.
  • the slots in the vertical supports connected by the diagonal supports lie opposite one another opposite and close to the axes of the vertical supports, so that of the Diagonal supports on the vertical supports at least no essential ones Torsional moments are exerted.
  • each must have two diagonal supports crossing each other be combined, which also consist of two halves, whereby Numerous components and work steps required for assembly are to achieve stable diagonal support,
  • the object of the present invention is to provide a framework to create the type mentioned, in which for the attachment of Diagonal supports have no special components on the vertical supports must be and from the diagonal supports to the vertical supports at least no significant torsional moments exerted in which, however, the diagonal supports with fewer components in fewer, easy to perform work steps can be stably mounted.
  • Diagonal supports used, but it is by the inventive, different training and securing of those provided at both ends Hook a stable assembly and arrangement of individual diagonal supports on two vertical supports with fewer components and in fewer, easy to perform steps.
  • FIG. 1 is a facade scaffold on a building 37 under construction.
  • On the ground 35 are four vertical supports 11 in an arrangement with a rectangular base area, the longer side of which is parallel to the front of building 37 extends, supported by height-adjustable spindle arrangements 36 and by upper cross members 38, longitudinal supports 39 and Diagonal struts 27 completed to a load-bearing base frame 41, which is suitable in Fig. 1 bottom right Way continues what is not shown in detail.
