  • fixing pins not shown
  • Such an attachment of the upper end of the foldable ladder 41 allows sliding movement of said end under the floor panel 4 in the packing position of the board 1.
  • the folding ladder 41 cooperates at its lower part with a retractable step 42, which is articulated at one end to the infrastructure of the formwork 1 and which is provided at its free end with hooks 43 or the like latching, in the service position, with the lower step of said foldable ladder 41.
  • a retractable step 42 which is articulated at one end to the infrastructure of the formwork 1 and which is provided at its free end with hooks 43 or the like latching, in the service position, with the lower step of said foldable ladder 41.
  • a platform according to the invention is carried out from a storage or packing position of a block 1, that is to say from a position of block 1 to horizontal, in which the platform 2 is folded against the infrastructure of the panel 1 in a pivoting position about the axis 8 of the self-locking bearings 7, as shown in Figure 3 of the accompanying drawings.
  • the railing 3 is put into service position by tilting from a position, not shown, in which it extends in extension of the platform 2 being connected to the latter through the intermediary of pins 24 cooperating with the guide grooves 23 'of the guide lugs 23 of the tubular housing elements 22, in its operating position shown in Figures 1 and 5.
  • the amounts 3' of the railing 3 are brought in extension of the tubular housing elements 22 and it suffices for the operator to lower the railing 3 to penetrate the ends of the uprights 3 'in said tubular elements 22.
  • This insertion of the ends of the uprights 3' is ensured by guiding the pins 24 in the guide grooves 23 ', so that the railing 3 is locked in its operating position.
  • the operator then performs the deployment operation of the platform 2 itself. For this purpose, he grasps the free end of the folding ladder 41, whose other end is slidably mounted under the floor panel 4 and is, in the folding position of the platform 2, partially engaged under this last.
  • the board 1 can then be operated, in the usual way, for its implementation on the site.
  • the foldable ladder 41 is locked in its operating position by simply folding the step 42 with hooking of the free end of the latter by the hooks 43 or the like on the lower rung of the scale 41.
  • the maneuver is carried out in the opposite way to that described above, that is to say that the form 1 is first laid horizontally. Then an operator realizes the unlocking of the locks 11 assigned to each pivoting mounting beam 5 by pressing the corresponding actuating lug 14 to move said latch 11 against the action of its return spring 15.
  • the latch 11 is thus completely cleared , at its ends, latching housings 17 and, by the action of the operator on the rod 18 for temporarily holding the latch 11 in the retracted position, it moves the stop 19 for retaining the latch 11 under said latch 11, so that the locking link in the service position of the platform 2 is interrupted.
  • the railing 3 is unfolded from its operating position in a horizontal position, parallel to the board 1 by lifting relative to the platform 2 to clear the lower ends of the uprights 3 'out of the elements tubular housing 22, with guiding, during the entire operation through the pins 24 cooperating with the guide grooves 23 'of the guide lugs 23, then, on arrival at the end of the pins 24 to the upper end of the grooves 23 ', by folding to the horizontal.
