Definitions

  • the invention relates to a working platform consisting of individual butt-jointed planks for scaffolding, in particular tubular steel scaffolding, in which the planks can be supported on the crossbars of the scaffolding with the aid of hooks fixedly arranged at their ends and can be locked on the crossbars by means of a locking device.
  • the locking device In a known work platform (French patent 2o 83 43o), the locking device consists of individual bars arranged pivotably at both ends of the boards. These lie in the latch position under their heavy weight on the circumference of a crossbar so that in cooperation with the hooks of the boards, unintentional detachment of the boards from the crossbar is prevented.
  • a locking device has a major disadvantage, which can be seen in the fact that each plank is provided with bolts at both ends must and that the bolts must be operated by hand. The assembly and disassembly of a scaffold is therefore relatively time-consuming.
  • the invention has for its object to simplify the locking of the planks on the crossbars of the scaffold in a work platform of the type described above.
  • each plank protrusions are firmly arranged, which after assembly of the planks are operatively connected to one end of the hooks arranged on the adjacent plank, the hooks with their other ends Reach under cross bars located between two planks.
  • planks lock themselves mutually on the crossbars when the work platform is being built, ie when the boards are supported on the crossbars of the scaffold.
  • the planks at both ends of the working platform i.e. the first and last plank to be secured in a suitable manner on the associated crossbars.
  • the work platform is then secured against unintentional lifting from the crossbars.
  • the boards can be detached from the crossbars in an equally simple manner after the two boards at the two ends of the working platform have been unlocked by the crossbars assigned to them.
  • the locking device according to the invention thus enables comparison to the known Verriegelun g s device faster assembly and dismantling of the scaffold.
  • an advantageous embodiment of the invention is that the projections are designed like a console and the one ends of the hooks which are operatively connected to the projections serve as supports.
  • the planks are secured on the crossbars of the scaffold provided that the scaffold is usually stiffened by longitudinal bars. Otherwise, it cannot be ruled out with absolute certainty that the planks will separate from one another when the tensile forces are applied to the work platform by lifting the hooks supported on the console-like projections from the projections and sliding off the crossbars together with the adjacent hooks.
  • the projections are arranged so that they engage under the ends of the hooks with which the latter engage under the cross bar after assembly of the planks at a distance from the ends.
  • two planks of the working platform are at one with 1.2 Designated tubular steel frame. These are provided at both ends with fittings 3.4, which are firmly connected to the planks 1, 2 by means of rivets 5.
  • the planks 1, 2 have two hooks 6, 6 'at both ends, of which the hooks 6 arranged at one end of the planks 1, 2 are offset from the hooks 6' arranged at the other end of the planks 1, 2 and with which the planks 1,2 can be supported on crossbars 7, 7 'of the scaffold.
  • two console-like projections 8 are arranged. The hooks 6, 6 'and the projections 8 are formed on the fitting 3 and 4, respectively.
  • the assembly of the planks is as follows.
  • the one-sided raised plank 1 is attached with its hooks 6 'located at one end to the crossbar 7' of the scaffold shown in dashed lines in FIG. 2 and then pivoted into the horizontal, with the one end of the hooks 6 'the crossbar 7' reaches under. It also supports the plank 1 in this position with the hook 6 located at its other end on the next cross bar 7. Thereafter, a one-sided raised plank 2 with one end of the hooks 6 'located at one end is placed on the console-like projections 8 of the adjacent plank 1 and then pivoted so far horizontally until the hooks 6' with their other ends the crossbar 7 have intervened (Figure 3). The plank 2 is supported in this position with the hook 6 located at its other end on the next cross bar.
  • planks of the working platform are installed in the same way.
  • the first and the last plank of the Work platforms are then secured in a suitable manner on the crossbars assigned to them. According to this, all planks of the working platform are secured against unintentional lifting off the crossbars on a scaffold that is stiffened by longitudinal bars.
  • the projections designated 8 'on the planks 1, 2 or on the fittings 3, 4 are arranged such that they have the ends of the hooks 6 "with which the Hook 6 "under the cross bar 7, reach under it at a distance from the ends.
  • the distance is dimensioned such that the boards 1, 2 can be assembled or disassembled without obstruction by the projections 8 '.
  • FIGS. 6 and 7 of the drawing The securing of the first and the last plank of the working platform is illustrated in FIGS. 6 and 7 of the drawing for a plank designated by 1. It is carried out by bolts 9 and 10, which, depending on whether the board 1 is at one end or the other at the working platform outside, is guided into the hooks 6 and 6 "and can be driven against the associated cross bar 7 so that the Floorboard is clamped to the crossbar.
