Definitions

  • the invention relates to a beam/floor board combination for system scaffolds having beams, mostly cross girders, for supporting floor boards, the extremities of the floor boards being provided with hitching means which will hitch across a portion of the beam.
  • the cross girder is designed as a U profile, in which hook-shaped means are hitched across both raised edges of the U-profile.
  • the hitching means can be made considerably more compact and robust than the members mentioned earlier; however, the hitching means will remain vulnerable during rough treatment on the building site. Since this concerns a closed frame system, the floor boards are prevented from blowing away in that the hitching means are covered by the upper scaffold frame. Such locking does not exist in a system scaffold having modular posts and beams. This would require an additional cross profile, which is difficult to realize in existing modular post systems.
  • the object of the present invention is to provide a solution for the difficulties mentioned above by which a suitable beam/floor board combination can be put on the market in a labour technically and economically sound way.
  • the beam/floor board combination according to the invention has been developed further, c.q. modified, in a novel way, characterized in that the cross-section of said beam is provided with a lower flange having raised edges at the extremities, with said hitching means hitching across the raised edges, said cross-section of the beam also being provided with a narrow upper flange, in which the intermediate distance L1 between two successive upper flanges of the beams is smaller than the total length L2 of the floor board plus hitching means and the length L2 in turn is smaller than the length L3 between the webs of the beams.
  • the floor board can be mounted to and be demounted from the beam in a smooth way and that if the floor board is blown up by the wind, this will only be possible at one side and across a small height, and that subsequently the floor board will be locked to the beam at the other side.
  • the cross-section of the beam allows the use of various profiles, such as an inverted T-profile, a rectangular or a U-shaped profile and transverse profile and the like, said transverse profile being provided with raised edges and a narrow upper flange.
  • the beam/floor board combination according to the invention has been developed such, that said hitching means at the extremities of the floor board for hitching across the raised edges of the beam are fastened to the floor board by means of shock absorbing intermediate layers.
  • the advantage is that on demounting the floor boards, parts will be thrown to the ground from the scaffold and will hit the hitching means, which will then be able to absorb the shock without getting damaged.
  • the beam/floor board combination has been developed further, characterized in that the resulting transverse profile of the beam is a hollow web having a narrow upper flange and a U-shaped bottom flange for receiving the hitching means at the extremities of the floor boards.
  • the advantage is a relatively low cross girder having a relatively large stiffness against bending and torsion and allowing for easy insertion of the hitching means.
  • the beam/floor board combination has been developed further, characterized in that said hitching means have an H-shaped transverse profile.
  • the advantage is that the floor boards can also be mounted and demounted in inverted positions.
  • the beam/floor board combination has been developed further, characterized in that said hitching means have an inverted U-shaped transverse profile.
  • the advantage is that the hitching means can be designed in a more robust cross-section, however, the floor boards can only be mounted in one position.
  • Figures 1A through 1D illustrate the mounting diagram of the floor board 1 in the mutually parallel beams 2 having e.g. a roughly inverted T-shaped cross-section.
  • the lower flange of the inverted T-shaped cross-section of the beams 2 have raised edges 3 at the lower flange 4 and a narrow upper flange 5.
  • the length L1 between upper flanges 5 is smaller than L2 being the complete floor board 1 having the hitching means 6, 7, 8, 9, 10 (see figures 4A-4C and 5A-B) and in turn smaller than L3 being the distance between the webs 11 of beam 2 having the inverted T-shaped cross-section (see also figure 3). Sliding in or mounting the floor board 1 is indicated by arrows and can therefore be deducted from figures 1A through 1D.
  • Figures 2A through 2D show the opposite, namely, demounting, and the complete proces can be deducted from these figures too.
  • Figure 3 shows locking of the beam/floor board combination.
  • the beam 1 can be inserted completely, then the other side of the floor board 1 can be blown up by the wind past the narrow upper flange 5, causing the floor board 1 to be at an angle ⁇ briefly, and then the hitching means 6, 7, 8, 9, 10 will be fixedly clamped between web 11 and the raised edge 3 of the lower flange 4. when the gust of wind disappears again, the end brought up will, with its hitching means, fall back onto the raised edge 3, etc.
  • FIGs 4A through 4C show a hitching means 6, 7, 8 having an H-shaped transverse profile. Then, the floor boards 1 can also be used in the opposite direction, which can be important when the floor boards are dirty. Between the hitching means 6, 7 of figurens 4A and 4B and the floor boards 1, a shock absorbing intermediate layer 12, 13 is mounted in order to protect edges 13 of the hitching means 6, 7 against excessive permanent distortion during rough treatment (floor boards 1 falling from the scaffold onto the ground) of the floor boards 1. In figure 4C, the entire hitching means 8 is designed in shock absorbing material 14.
  • the hitching means 9, 10 is designed with a U-shaped transverse profile.
  • a shock absorbing intermediate layer 15 is mounted and in figure 5B, the shock absorbing intermediate layer 16 is combined with a hook 17.
  • floor board 1 is designed as metal plate 18 having edges 19 all round.
