Preferably, the two adjacent sides 11a 11b of the square part 11 have, in cross section, a T-shape which can engage in the profile of a corresponding element T or P of the console structure 1 so as to retain the part at right angle 11 to this element.

  The railing post member P may adopt first and second mounting positions on the crossbar member T. In the first position, the railing post member P is perpendicular to the crossbar member T, as shown in FIGS. 2, 3 and 4. In this first position, the railing post element P is held by the square-shaped part 11 whose adjacent sides 11a, 11b are respectively engaged in the two sections. members forming a crossbar T and forming a railing post P. The latter is thus resting on the hypotenuse side 11c of the square-shaped part 11.

  In second position, the railing post member P is inclined relative to the crossbar member T, as shown in FIG. 1. In this second position, the railing post member P is held by the workpiece. in the form of a bracket 11, one of the adjacent sides 11a is engaged in the profile of the cross member T element and whose hypotenuse side 11c is engaged in the profile of the railing post element P.

  The square piece 11 is locked in translation relative to the profile of the horizontal cross member T through a bolt 12 through the opposite holes 2p, 3p, 4p of the side walls of the section of the element. forming a crossbar T and engaging in a notch 13a on the adjacent side 11a of the square-shaped piece 11. The square-shaped piece 11 is locked in translation relative to the profile of the vertical railing post member P via a pin 14 passing through opposite holes 2p, 3p, 4p of the side walls of the section of the railing member element P and engaging either in a notch 13b on the adjacent side 11b of the part in the form of a square 11 when the railing post member P occupies its first position, or in a perforation 13c of the hypotenuse side 11c when the railing post member P occupies its second position tion. FIG. 11 shows an alternative embodiment of the console structure 1 in which the jamb member J comprises two sections 2, 4 assembled to one another so as to allow their relative sliding in the longitudinal direction. To do this, the profiles 2, 4 have a constant cross section H-shaped as shown in Figure 13, or in the form of read, as shown in Figure 14 and cooperate as shown in Figure 12. In the configuration of Figure 11, the element 3 form crosses T of the console structure 1. An element 4, read, is supported on the ground S via a mooring 9 shaped sole.

The jamb member J is extended by a third section 4 ', to read, which is slidably guided along the section 2 jamb J to form the element forming railing post P.

  In this configuration mode, the jamb J is fixed to the crossbar T via the third profile 4 '. This embodiment of the jamb J in at least two profiles 2, 4 assembled to one another can increase the length of the jamb J with ground fixing S according to the mounting height of the cross member T of the structure of 1 in the wall M. In each of the configurations shown in Figures 1 to 4 and 11, the scaffolding console structure 1 comprises an additional leg 15. This additional leg 15 is removably attached by its ends 15a, 15b between the element forming a cross member T and the leg member J at a position to adjust and maintain the leg member J at an inclined position relative to the cross member member T under the latter. Each end 15a and 15b of the additional leg 15 is respectively fixed to the cross member T and to the jamb member J by means of an assembly key 5 identical to those for fixing the profiles 2, 3 , 4 to each other. As shown in Figure 15, the end 5a of the assembly key 5 is engaged in the end portion 15b of a profile forming the additional leg 15 and secured thereto by a bolt 6 through the hole d 8a end of the assembly key 5 and opposite holes of the side walls of the profile forming the additional leg 15. The opposite end 5b of the assembly key 5 is attached to the jamb member J via a pin 7 passing through the end hole 8b of the assembly key 5 and through opposite holes 2p, 3p, 4p of the side walls of the profile 2, 3, 4 forming jamb J. The intermediate portion 5c of the key assembly 5 is not engaged in the profile of the additional leg 15 so that it can pivot relative to the jamb member J to be able to adjust the inclination of the jamb J and bring the docking 9 in support on the wall M.

  It should be noted that the additional leg 15 is not interchangeable with the elements 2, 3, 4 of the console structure 1. The invention also relates to a scaffolding system 30, shown in FIG. Scaffolding Console Structures 1. These structures 1 are installed on the wall M while being arranged parallel to each other along this wall M. The scaffolding system 30 comprises a scaffolding floor 16 shown in FIGS. 16A and 16B . The floor 16 consists of a longitudinal and end-to-end assembly of 16m and 16f male plank elements. A male element 16m is connected to a female element 16f by at least one clip 17 for clamping the upper rails 16'm and 16'f male and female elements 16m, 16f to one another. This floor 16 is removably attached to the various elements forming horizontal crosspieces T of the console structures 1 by anchoring means 18, 19, 20, 21 shown in FIG. 17. These anchoring means comprise a piece forming a ring. anchoring 18, visible in Figure 18 and secured to the cross member T through a pin 19 through a hole 18p of the anchor ring member 18 and two opposite holes of the T-member forming element.

  These anchoring means also comprise a hook 20 surrounding an edge 16b of the floor 16 and one end 20a of which is connected, via a spring 21, to the ring 18a of the anchoring ring piece 18.

  Thus, under the effect of the spring 21, the floor 16 is pressed against the cross member T element on which it is placed. The scaffolding system 30 comprises horizontal, parallel rails 22 and fastened to the guardrail post members P of the console structures 1 via clamping collars 23, as can be seen in FIG. 20, each clamp 23 is constituted by a semi-circular rigid part of which one of the ends 23a is pivotally mounted in the profile of the railing post element P and whose opposite end 23b can be removably fixed in this profile. To do this, each end 23a, 23b of a clamp 23 has a hole 23'a, 23'b intended to be traversed by a pin 24 also passing through two opposite holes 2p, 3p, 4p of the element 2, 3, 4 forming railing post P. Each clamp 23 comprises a core having two arcuate cutouts 25, 26 of different radii and able to grip respectively two corresponding rails 22 of different diameters. As can be seen in FIGS. 21 and 22, the rails 22 are connected coaxially end-to-end by means of sleeves 27 comprising fingers 28 intended to engage elastically in end holes 22p of the rails 22 to fix each rail 22 to sleeve 27. The scaffolding console structure according to the invention offers the advantage of being flexible and adaptable, once on the site, to the dimensional constraints of it.
