Definitions

  • the invention relates to a new scaffolding bracing, as well as the scaffolding elements or frames allowing the mounting of this bracing.
  • scaffolding be provided, on their front face, with bracing, or with railings and plinths, in order to ensure the safety of workers working on the scaffolding.
  • the bracing generally consists of two rods mounted obliquely in a cross between two scaffolding frames located at the same level and spaced from each other by a predetermined distance generally corresponding to the length of a section of floor.
  • the bars forming a spacer are fixed at their ends to the vertical uprights of the frames by means of sliding key collars.
  • the object of the present invention is precisely to avoid all the drawbacks presented by the bracing systems of the current technique.
  • a bracing for scaffolding comprising two bars forming a spacer mounted obliquely in a cross on the front face of the scaffolding between parallel vertical scaffolding elements or frame spaced apart by a predetermined distance, the two spacer bars being fixed at their ends on vertical uprights of said frames, characterized in that each spacer bar consists of a straight bar, for example a cylindrical tubular, the end parts of which are bent so that one of these bent parts extends horizontally and the other extends vertically when said spacer bar is mounted obliquely in the desired position between two scaffolding frames.
  • each above-mentioned bent part is extended by a mounting part on the corresponding frame, and this part mounting extends perpendicular to the bent part.
  • each spacer bar is mounted and fixed on the corresponding vertical upright of the scaffolding frame, simply by introducing one end of its mounting part comprising an unbalanced stud in a hole a mounting lug secured to the frame upright.
  • the bracing can only be mounted in one position on the scaffolding, which prohibits any mounting error of the bracing, any incorrect positioning of the bracing, etc.
  • a mounted scaffolding part comprising the bracing according to the invention, is shown diagrammatically in FIG. 1.
  • This scaffolding part is intended for example to be mounted along a vertical wall, not shown, which would be parallel to the plane of the drawing and located behind the scaffolding.
  • This scaffolding comprises two vertical rows 11 and 12 of frames or scaffolding elements 13, mounted one at the end of the other.
  • Two spacers 14 extending between the two vertical rows 11 and 12 of frames 13, have been shown in FIG. 1.
  • Each spacer 14 is formed by two spacer bars 15 arranged in a cross and which are fixed by their ends on vertical uprights of the frames 13, as will be described in more detail below.
  • Each spacer 15, in the embodiment shown, consists of a straight cylindrical tubular bar, the two ends of which are bent.
  • a first end 16 of the spacer 15 is bent so that its longitudinal axis makes an angle ⁇ of 142 ° with the longitudinal axis of the straight part of the bar 15, while the second end 17 of the bar 15 is bent so that its longitudinal axis makes with the longitudinal axis of the right part of bar 15 an angle t of 128 °.
  • the longitudinal axes of the bent end portions 16 and 17 are perpendicular to each other.
  • This arrangement is such that, when the spacer 15 is mounted in place on a scaffolding as shown in FIG. 1, the longitudinal axis of the bent end part 16 is horizontal, while the longitudinal axis of the bent part 17 end is vertical.
  • Each bent part 16 and 17 is extended, perpendicular to its longitudinal axis, by a mounting part 18 which is shown in more detail in ' Figures 7 and 8.
  • These mounting parts have substantially the shape of an L and are mounted fitted and welded, by their short side, to the end of the corresponding bent part 16, 17. The long side of the mounting part 18 therefore extends perpendicular to the longitudinal axis of the bent part 16, 17.
  • Each mounting piece is formed by folding a metal plate so as to have a substantially U-shaped cross section.
  • the end of the long side of each mounting piece 18 comprises a imbalance locking pin 19 which is pivotally mounted, inside the part 18 near its end, about a transverse axis 20 so as to be able to occupy only a locking position shown in FIG. 8 and an inactive position in which the stud 19 is raised by 90 ° relative to the locking position, and is thus housed entirely inside the part 18.
  • the center of gravity of the stud 19 is spaced from its pivot axis 20, we understands that, when the part 18 is in the position shown in FIG. 8, the stud 19 switches itself into the locking position shown under the effect of its own weight.
  • the mounting piece 18 which is provided at the bent end 16 of the spacer 15 extends perpendicular to this bent end, in the plane defined by the axes of the straight part of the spacer 15 and the bent part 16
  • the mounting part 18 provided at the bent end 17 extends perpendicular to the plane defined by the axis of the straight part of the spacer 15 and the axis of the bent part 17.
  • Each frame 13 of the scaffolding essentially comprises, as best seen in FIG. 2, two vertical uprights 21 which are joined together, near their upper ends, by a transverse bar 22. Oblique reinforcements 23 are provided between the crossbar 22 and each of the uprights vertical 21, as shown in FIG. 2.
  • the lower end of one of the uprights 21 constitutes a male interlocking element, and its upper end constitutes a female interlocking element, while the lower end of the other upright 21 constitutes a female element , and its upper end constitutes a male interlocking element.
  • each upright 21 comprises a horizontal tab 24 for attaching or hooking one end of a spacer 15, and a vertical tab 25 for attaching or hooking the opposite end of a another spacer 15.
  • These tabs 24 and 25 are shown in more detail in Figures 3,8 and 4, 7 respectively.
  • Each horizontal tab 24 comprises two half-tabs 26 of substantially triangular shape, which are arranged symmetrically and at the same level around the vertical tubular upright 21, and which comprise a semi-circular collar 27 by means of which they are welded by bosses on the upright 21.
  • These horizontal half-legs 26 extend horizontally, and perpendicular to the plane defined by the frame 13. They each have a circular hole 29 allowing the passage of the long side of a mounting piece 18, as shown in FIG. 8.
  • Each vertical leg 25 is formed in one piece, and comprises two straight wings 30 joined together by a semi-circular part 31 by means of which they are welded by bosses on the upright 21.
  • Each straight wing 30 comprises a hole 32 allowing the passage of the long side of a mounting piece 18 of a spacer 15.
  • the vertical legs 25 extend perpendicular to the plane defined by a frame 13.
  • the lugs 24 and 25 of each upright 21 are provided in the vicinity of the upper end of the upright, the horizontal lug 24 being located above the crosspiece 22 of the frame 13, and the vertical tab 25 being located below this crosspiece.
  • FIG 5 there is shown an alternative embodiment of a frame 13a, which differs from the frame 13 in that it comprises a single reinforcement 23 between the crosspiece 22 and one of the uprights 21, and in that a ladder 33 is formed between the other upright 21 and the crosspiece 22, in the plane of the frame 13a.
  • the frame 13a comprises horizontal and vertical tabs 24 and 25 for attaching or hooking the spacers.
  • the uprights 21 of the frames 13 and 13a comprise, a little above their lower end, two horizontal lugs 35 for attachment or attachment, which are identical to the horizontal lugs 24, and which are intended for example to the hanging of a railing.
  • the vertical lateral uprights of the railings each comprise two mounting parts, identical to the mounting parts 18 of the spacers 15, making it possible to hang them on the horizontal lugs 35.
  • the spacers and scaffolding frames according to the invention are used as follows: For the mounting of the scaffolding, the frames 13 and / or 13a are mounted one at the end of the other, as shown in FIG. 1, the male and female parts formed at the lower ends of the uprights 21 of a frame being fitted in the female and male interlocking parts respectively formed at the upper ends of the uprights 21 of a lower frame 13 or 13a.
  • the procedure is as follows: a worker takes a spacer 15, and, holding it obliquely roughly in the position shown in FIG.
  • the worker introduces the mounting piece 18 of the bent upper end 17 of the spacer 15 into the hole 32 of the vertical tab 25 of the frame 13 or 13a which is located at the upper level, and on the opposite side of the scaffolding part to be braced.
  • the attachment of the lower part 16 of the spacer 15 it suffices to push the long side of the mounting piece 18 into the hole 32, the stud 19 placing itself in the locking position as soon as 'he came out of hole 32.
  • the bracing 14 makes it possible to rigidly join the two frames 13 of a level of the scaffolding to the two frames 13 of the immediately lower level of the scaffolding which avoids any risk of accidental disengagement of the frames 13 mounted vertically one after the other.
  • the particular configuration of the spacers 15 absolutely prohibits any risk of mounting these spacers backwards.
  • the part 17 of a spacer cannot be hung on a horizontal tab 24, and likewise, the bent part 16 of a spacer 15 cannot be hung on a vertical tab 25.
  • the horizontal phantom lines 40 of FIG. 1 schematically represent the scaffolding floors, which are carried directly by the crossbeams 22 of the frames 13 and / or 13a.
  • the length of the long side of the mounting lugs 18 is much greater than what is necessary for the precise mounting of the spacers. This great length makes it possible to compensate for the height differences due to manufacturing tolerances and slight assembly faults.
  • spacers 15 are simply fixed by their mounting pieces 18 introduced into round holes, they do not need to occupy a determined angular orientation at the time of their mounting, which facilitates operations.
