Definitions

  • the vertical structure of rectangular horizontal section includes two opposite scales and connected to each other by crossbars or diagonals. These scales generally correspond to the short sides of the rectangular horizontal section, while the braces or diagonals correspond to the long sides of this section.
  • a metal frame ensures the mechanical resistance of the tray and the plinth function, and a plywood panel inserted in the frame provides the floor function.
  • a second difficulty lies in adjusting the level of the tray. Indeed, for height positioning needs to work in the ceiling, it is often necessary to vertically move the tray of a bar or two. This operation requires two people, because it is necessary to lift the plate to release its hooks from the bars, tilt the plate so that the hooks escape these bars during the vertical adjustment movement, and reposition it horizontally often by engaging the plate between bars. This operation is not only dangerous but also difficult to perform, because the operators must stand outside the ladders, while holding the tray inside the vertical structure.
  • a third difficulty lies in the installation of scales and diagonals. These, according to a known operating mode, are hoisted to the top of the structure using ropes or manually, the ladder nesting operation being possible only if the operator releases his body outside of the structure, while being attached to the structure with its legs. It is a dangerous operation.
  • Another method consists in placing the trays approximately every two meters and in constructing the scaffolding from said trays. This operation remains long and requires a large number of trays, which is not always advantageous, especially for great heights where you only need the last tray to work.
  • scaffolding plates have already been proposed provided, at their ends, with hooks mounted pivoting about substantially horizontal axes, which in the assembled position of the plate s' extend parallel to the bars of the ladders, so that the hooks can be erased by pivoting in the space requirement of the tray.
  • These pivoting hooks have in their upper part a ramp configuration allowing them to automatically disappear when a bar passes, then to automatically reposition themselves above this bar, during an elevation movement of the plate.
  • said pivoting hooks situated outside the longitudinal sides of the frame of the plate, respectively near its four angles, comprise, towards the two ends, respectively inner and outer, of their upper part, mooring points for a rope or a traction cable used for hoisting or lowering this platform inside the vertical structure of the scaffolding, the mooring point used tends to align with the vertical of the pivot axes when the rope or pull cable is stretched.
  • the scaffolding plate according to the invention offers the advantage of being able to be hoisted or lowered, inside the vertical structure of the scaffolding, thanks to ropes or traction cables linked to the pivoting hooks in judiciously chosen mooring points.
  • the hooks not only ensure the connection between the scaffolding plate and a ladder bar, when this plate is brought to the level desired, but still these hooks are an integral part of the traction chain, allowing the platform to be raised to a higher level or lowered.
  • the present invention also provides a scaffolding mounting system, in particular a rolling scaffolding, using the swivel hook plate previously defined, this mounting system comprising at least two ropes or traction cables whose ends are attached to the points of mooring provided on the upper parts of said hooks, and which pass over respective return pulleys, of substantially horizontal axis, positioned towards the top of the scales of the vertical structure of the scaffolding.
  • the two traction cords associated respectively with the two ends of the plate scaffolding each have, in addition to their strand extending between the pivoting hooks and the corresponding return pulley, another strand extending from the corresponding return pulley to the ground.
  • the traction on the two ropes can be exerted from the ground, or quite safely, by two operators, this to hoist a tray to the chosen level, the hooks of the tray automatically disappearing with each passage of a bar according the principle set out above.
  • This simple and inexpensive embodiment allows the rapid assembly, adjustment and disassembly of the scaffolding platform (s).
  • the two traction cables associated respectively with the two ends of the scaffolding plate each have, in addition to their strand extending between the pivoting hooks and the corresponding return pulley, another strand extending from the corresponding return pulley to a winch carried by the scaffolding plate itself.
  • the hoisting of the platform is thus achievable by operators posted on this platform, who actuate or control the winches so as to wind the cables and thus cause the elevation of the platform, whose pivoting hooks are erased as before the passage of the bars .
  • the scaffolding plate 7, of generally rectangular shape, has a metal frame 8 into which is inserted a horizontal plywood panel 9, forming a floor capable of supporting people and equipment.
  • the scaffolding plate 7 can be moved, in the direction of its hoisting or its descent, at the by means of two traction cords 16 and 17, which pass over respective return pulleys 18 and 19 with a horizontal axis mounted, respectively, at the top of the two opposite scales 3 as shown in FIG. 1, and as also shown, more schematically, Figures 2 to 5.
  • Each rope 16 or 17 has a first strand, which is subdivided into two end parts 20 intended to be moored respectively at points 15 'and 15''of the two hooks 10 at the same end of the plate 7.
  • the other strand of each rope 16 or 17 extends from the corresponding return pulley 18 or 19 to the ground, and can thus be actuated by an operator posted on the ground.
  • each hook 10 comes into contact at a given moment, by its edge 14 forming a ramp, with a bar 6.
  • the cooperation of the bar 6 and the ramp 14 repels the hook 10 inward, this hook pivoting about its axis 13 as shown in FIG. 4.
  • the hook 10 automatically returns to position in the space between two consecutive bars 6 (return to the position of Figure 3).
  • the two ropes 16 and 17 being pulled in a synchronized manner, by two operators posted on the ground on either side of the scaffolding, the plate 7 can thus be hoisted inside the vertical structure, crossing without difficulty all the bars 6 encountered, and while remaining horizontal, the length L of this plate 7 being less than the center distance E of the two scales 3.
  • the two ropes 16 and 17 are attached, by their end portions 20, to the mooring points 15 '' located on the outside of the upper parts 12 of the hooks 10 - see Figure 5.
  • the mooring points 15 '' then tend to align with the vertical of the hinge pin 13, this for each hook 10.
  • the hooking lugs of the four hooks 10 are thus brought back from the bars 6 of the ladders 3, these hooks 10 being kept erased in the space taken up by the plate 7.
  • the two ropes 16 and 17 being actuated in a suitable direction indicated by arrows G, still by operators posted on the ground, the plate 7 can thus be lowered without encountering any obstacle, in particular without hitting the bars 6.
