The key (8) then slides until entering the hole (70) to tighten in force a scaffolding tube (9) which would have been placed in the collar (7).
  • the panels thus equipped can be used both for roofers when removing the stirrups which can constitute obstacles to walking of the roofer and still allow the roofer to tie the panel located in roof edge with scaffolding incorporating a stirrup connecting with the panel and linking this stirrup to a scaffolding tube.

But it is possible to provide tubes (199) of which the longitudinal axes of symmetry of the legs (91A, 91B) are perpendicular to the axis of symmetry of the tube (199), so that in the lateral assembly position of two panels (1A, 1B), the tube (199) is perpendicular to the angles (11A, 10B).
  • Figures 8C and 8D show two alternative means lateral assembly of two modular elements (1A, 1B) according to the invention.
  • the assembly element (270) of FIG. 8C consists of a part having substantially U-shaped with a first (273) leg forming a surface plane on which is made at least in translation a collar (7) in U.
  • the U-shaped collar (7) integral with the assembly element (270) is substantially identical to that of FIG. 7D.
  • the second leg of the element assembly (270) is formed by two legs (271, 272) slightly parallel spaced apart and substantially identical to the first (171) leg of the part (170) U-shaped connection of Figure 7D.
  • the assembly part (270) allows the lateral joining of two adjacent panels (1A, 1B) by the introduction and tightening of the two tabs (271, 272) in the orifices of two stirrups (6A, 6B) belonging to two adjacent panels (1A, 1B).
  • the means of lateral assembly of two modular elements (1A, 1B) of Figure 8D consists of a double U-shaped collar (370) in length corresponding substantially to twice the length of the U-shaped collars (7) described above or simple U-shaped collars (in particular in FIGS. 7D, 8C).
  • a necklace in a simple U (7) is made integral at least in translation with the base (371) of the double U-shaped collar (370).
  • the U-shaped collar (7) simple is intended to accommodate a scaffolding tube fixed by means of a tightening key.
  • the double U-shaped collar (370) is provided, substantially in its middle, of a transverse cut (372) in its two parallel legs.
  • the transverse cutout (372) is intended to accommodate the two angles (11A, 10B, FIG. 8B) joined to two adjacent panels (1A, 1B).
  • the legs of the double U-shaped collar (370) are provided with orifices or slots allowing the connection lateral of two adjacent panels (1A, 1B) by the introduction and tightening of two keys (175) in the respective superposed holes of the double collar (370) and two stirrups (6A, 6B) belonging to two panels (1A, 1B) adjacent side to side.
  • FIGS. 10A and 10B represent a fourth variant of embodiment of the invention using a support piece (300) consisting of a bar (301) secured by a first of its ends to the surface upper of a flat plate (302) parallel to the axis of symmetry longitudinal of the bar (301).
  • the second end of the bar (301) is intended to be mounted on a bracket (6) of a panel, the bar (301) being at horse on the angle (10).
  • the bar (301) has a U-shaped section and is integral of the plate (302) by the ends of the two legs of the U.
  • the lower surface of the plate (302) is provided with one or two flexible and adherent coatings (2, 22).
  • the second end of the bar (301) is provided with two rectangular slots perpendicular to the legs of the tube (301) and substantially identical to the slots of the stirrups (6) of FIG. 7A. Only a rectangular slot (361) is visible in Figures 10A and 10B.
  • the two slots (361) of the bar (301) are intended to be superimposed on the slots (161, 162) of a stirrup (6) in order to be able fasten, using a clamping key, the bar (301) to the support of the panel (1).
  • the bar (301) is also provided with a cutout (303) formed transversely in the two legs of its U-shaped section.
  • cutout (303) is provided to allow mounting of the bar (301) on a angle iron (10), the angle iron being housed in the cutout (303) and the second end of the tube provided with the slots (361) is mounted on the bracket. So the bar (301) is arranged in the extension of a bar, the covering (2, 22) of the plate resting on the roof (302). Significantly above the cutout (303), the upper face of the bar (301) forming the base of the U-shaped section is provided with a cylinder (304) perpendicular to the bar (301) and intended to receive a tube (9, FIG. 10A) of threaded scaffolding and or fixed on the cylinder (304).
  • the support piece (s) (300) mounted on a line of connected panels (1) make it possible to start scaffolding or to mount guardrails for workers on assembled panel lines and simultaneously guarantee the stability of the whole. Thanks to the invention it is for example possible to build railings (400, figure 11) longitudinal along a line of assembled panels or railings (401, FIG. 11) transverse, that is to say between two angles, perpendicular to these. Likewise, it is possible to constitute railings (402, Figure 11) between two or more lines of panels assembled.
