Definitions

  • the present invention relates to the technical field of scaffolding.
  • sealing is meant here any temporary building or structure, fixed or movable, facilitating access to works and carrying out work.
  • the invention finds a particularly advantageous application for rapid scaffolding.
  • a scaffold In a conventional assembly, of rather old design, a scaffold comprises vertical uprights, formerly called poles, pegs, pins, fixed or wedged to the ground on soles or pads, these amounts being spaced in the direction of the length of the scaffolding horizontal spars (dies, longrins, or tendons). Transversally, sleepers or boulins carry floors. The elements are assembled for example by lashings of ropes or chains. The whole is stiffened by cross struts of St. Andrew and provided with smooth or railing.
  • a conventional scaffold comprises two ladders with stiles and tubular steps and of round section, the ladders being connected to each other vertically by at least two diagonal bars fixed in cross and on each side of the scaffolding , the bars being fixed at their ends to ladder steps.
  • the scaffolding includes sleepers such as horizontal dies, tendons, balls, handling members, platform support, diagonal bracing struts, separately connected to the uprights or pegs.
  • sleepers such as horizontal dies, tendons, balls, handling members, platform support, diagonal bracing struts, separately connected to the uprights or pegs.
  • the invention also finds an application for rolling scalding called platforms.
  • platform is meant here in particular small collapsible platforms, known in themselves for a long time: see for example the US patent 2,599,670 published in 1952 .
  • These platforms are particularly used for the work, for example painting, inside buildings.
  • folding folding scaffolds As a guide, we currently know on the market such platforms in aluminum tubes (called folding folding scaffolds) having the following dimensions: length 1.9 m, width 0.8 m, maximum working height 2.8 m, for a maximum load of 200 kg per meter, these platforms once folded, passing through the doors. These dimensions are only indicative.
  • Such platforms are conventionally at least partly foldable and / or removable, so as to reduce their size and to facilitate their storage and transport.
  • the invention more particularly relates to a scaffolding support leg or platform.
  • the weight of the scaffolding is in fact conventionally taken directly by its vertical uprights, the scaffolding being also very often fixed against the structure of the building.
  • the document FR 2 821 103 describes the use of weights fixed on the struts of a scaffold, so as to improve the resistance to tilting, for example when scaffolding is subject to wind.
  • the document FR 2,819,533 describes a scaffold support leg, this leg comprising two telescopic tubular elements, a free end of one of the elements resting on the ground, while the other element is articulated in rotation to the scaffolding. Disengageable locking means prevents length reduction of the support leg.
  • a connecting arm connects the support leg to a vertical upright of the scaffold, the link arm being pivotally mounted relative to the scaffold amount and relative to one of the telescopic elements.
  • the device described in the document FR 2,819,533 has many disadvantages.
  • it is not adaptable to different profiles of scaffold amounts, and no means can adjust the angle of inclination of the support leg. In some cases, such a setting is very useful, especially when there is little floor space available.
  • the invention aims in particular to overcome these disadvantages by providing a support leg structure for a very versatile use: different site conditions, various types of scaffolding.
  • the invention relates, in a first aspect, to means for assembling a support leg to a scaffolding post, these means comprising a plate-shaped connecting piece and a piece of hook-shaped clamping, the connecting piece comprising a first end portion forming a mounting flange for the support leg foot, the connecting piece comprising a second end portion provided with through holes for both ends of the support piece; the first end portion of the connecting piece extending at an angle of between 20 and 70 degrees to the second end portion of the connecting piece and more particularly about 45 degrees, the clamping piece and the second end portion of the connecting piece defining, by their assembly, a passage opening to the scaffolding post, means allowing the clamping the clamping piece to the connecting piece.
  • the second end portion of the connecting piece is in the form of angle
  • one of the wings is provided with at least two through holes for an end portion of the clamping piece.
  • the hook-shaped clamping piece comprises a first end portion provided with a thread and a second U-shaped end portion with a flat or curved bottom, said clamping means comprising screwing means.
  • the invention relates, in a second aspect, to a scaffolding support leg comprising assembly means as presented above, the support leg foot comprising two sliding tubes, one of the tubes being mounted bearing against one of the faces of said mounting bracket.
  • the support leg foot further comprises a sleeve, with respect to which at least two tubes are slidably mounted.
  • the foot further comprises a spacer arm mounted articulated on said sleeve.
  • the leg comprises assembly means as presented above, at the extreme end of its spacer arm, for assembling this spacer arm to a scaffold amount.
  • the invention also relates to a scaffolding comprising at least one leg as presented previously, or assembly means of a support leg as presented above, this scaffolding comprising amounts of round section, oval, square or polygonal.
  • the strut shown in Figure 1 extends substantially in a plane and comprises two substantially aligned tubes 1, 2 each mounted sliding in a sleeve 3.
  • a first tube 1, lower, is provided at its free end portion, a pad 4.
  • This first tube 1 and the sleeve 3 are provided with mutual assembly means allowing adjustment of the total length of the assembly they form.
  • the first tube 1 is provided with holes coming opposite at least one orifice 5 formed in the sleeve 3, a locking member such as a pin (not shown) passing through this orifice 5 and the first tube 1.
  • the second tube 2, upper, and the sleeve 3 are also provided with mutual assembly means allowing adjustment of the total length of the assembly they form.
  • the second tube 2 is provided with holes coming opposite at least one orifice 6 formed in the sleeve 3, a locking member such as a pin (not shown) passing through this orifice 6 and the second tube 2.
  • the two tubes 1, 2 are advantageously substantially identical.
  • these two tubes are circular in section and made of aluminum alloy or steel.
  • these two tubes have a diameter of 35 mm, the sleeve 3 having a diameter of 40 mm.
  • a spacer bar 7 is hingedly mounted on the sleeve 3.
  • this articulation is obtained by a stirrup 8 fixed on the sleeve 3, for example by screwing, welding or any other equivalent method.
  • This stirrup 8 defines a passage for a hinge axis 9 of the spacer bar 7.
  • the spacer bar 7 is provided with first assembly means of the supporting leg to a scaffold amount.
  • the second tube 2 is also provided, at its free end opposite the sleeve 3, second assembly means of the support leg to a scaffold amount.
  • the first and second assembly means have substantially identical structures.
  • these first and second assembly means are identical.
  • the following description relates only to the first assembly means, it being understood that what will be said for these first means must be transposed for the second means.
  • These assembly means comprise a connecting piece 10 and a clamping piece 11.
  • the connecting piece 10 is shown, in side view, in Figure 12, in one embodiment.
  • This connecting piece 10 comprises a first end portion 12 defining two contact surfaces 13, 14 with the second tube 2. These contact surfaces 13, 14 are advantageously flat, the second tube 2 can thus be indifferently of round, square section, rectangular or polygonal. In certain embodiments, not shown, the first end portion 12 is shaped in counterprint of the section of the second tube 2, so as to be able to marry the curve.
  • the first end portion 12 of the connecting piece 10 is provided with a through hole through which an assembly member such as a wing nut screw 16, or any other equivalent reversible mounting member (for example a pin can pass). ).
  • the connecting piece 10 comprises a second end portion 17 shaped angle, and therefore comprises two wings 18, 19 substantially perpendicular.
  • this second end portion 17 does not depend on the shape of the cross section of the scaffolding upright.
  • the second end portion 17 in the form of an angle can easily be pressed against a square or rectangular upright 20 of scaffolding.
  • the connecting piece 10 can also be used very effectively when the upright 20 is of round section or other.
  • This clamping piece 11 comprises a first substantially straight end portion 21 provided in the vicinity of its free end with a thread 22 for a nut, for example a butterfly 23.
  • This clamping piece 11 comprises a second end portion 24 in the form of a hook.
  • the first end portion 21 of the hand 11 is intended to pass through at least one hole 25 formed in the second end portion of the connecting piece 10.
  • the second end portion 24 of the hand 11 is intended to pass through at least one hole 26 formed in the connecting piece 10, between the two end portions 12, 17.
  • the clamping piece 11 can have various shapes and sizes.
  • this hand 11 has a U-shaped hook, the bottom wall of the U and the two wings being substantially perpendicular. A use of such a hand 11 is illustrated in FIGS. 4 and 5 for mounting a support leg on a round section scaffolding post.
  • this hand 11 has a U-shaped hook shape, the bottom wall of the U being curved, in contrast with the embodiment of FIG. 10.
  • a use of such a hand 11 is illustrated in FIGS. 7 for mounting a support leg on an amount 20 scaffold oblong section.
  • Another use of such a hand 11 is illustrated in Figures 8 and 9 for mounting a support leg on an upright 20 of rectangular section.
  • the support leg 1 comprises two tubes 1, 2 slidably mounted with respect to each other, the spacer rod 7 being articulated directly to the upper tube 2, without a sleeve. 3.
  • Figures 4 and 5 show first that the strut can be set in rotation relative to the axis of slenderness of the scaffold upright, especially when this upright 20 is round or oval section. To do this, before tightening the wing nut 23, it is sufficient to rotate the clamping piece assembly 11 / connecting piece 10 to obtain the desired orientation for the support leg. By tightening the wing nut 23, the upright 20 is then clamped between the hand 11 and the connecting piece 10.
  • Figure 2 shows how it is possible to change the position of the strut mounting areas along a scaffold upright, especially when this post is of rectangular section.
  • FIG. 4 shows how it is possible to fit the support leg to different sections of upright.
  • the upright 20 is of circular section and the hand 11 passes through a first hole 25a of the second end portion 17 of the connecting piece 10.
  • FIG. amount 20 is now oblong section: its smaller diameter may be smaller than the diameter of the upright 20 of Figure 4, its largest diameter may be greater than the diameter of the amount 20 of Figure 4.
  • the adaptation is performed in the manner next: the clamping piece no longer passes through the hole 25a but through another hole 25b of the second end portion of the connecting piece 10.
  • the two holes 25a, 25b are replaced by an oblong hole.
  • Figures 7 and 9 show that it is also possible to mount the second rod 2 (and the spacer bar 7) not on the first end portion 12 of the connecting piece 10, but on the second end portion 17 of this piece 10.
  • the wing nut (or any other equivalent means) is tightened the second rod 2 (or the spacer bar 7) against the second end portion 17 of the connecting piece 10, the piece of clamping through the rod 2 (or the spacer bar 7). It is thus possible to place the support leg in a plane substantially parallel to the plane of the scaffolding uprights. It is also possible to fix an additional support (not shown) on the first end portion 12 of the connecting pieces 10, in this configuration of FIGS. 7 and 9.
  • attachment zone, on the upright 20, of the second rod 2 and the mounting area on the upright 20 of the spacer bar 7 can be adjusted independently. Once this adjustment is made, the operator can advantageously leave in place the connecting pieces 10 and clamping piece 11, and disassemble the assembly formed by the tubes 1, 2 and the sleeve 3. The operator will immediately find a good setting during the next use.
  • the strut In four first positions, the strut is substantially at 45 ° to the vertical planes P1, P2 of the scaffold. This angle of 45 ° is derived from the angle formed by the first end portion 12 of the connecting piece 10 with the bearing surfaces of this connecting piece 10 against the square or rectangular upright 20 of scaffolding. Although tense, this angle could be different from 45 °. This position of the support legs is shown in FIG.
  • the strut is substantially 90 ° to the vertical planes P1, P2 of the scaffold, in practice the vertical planes front and rear. This configuration corresponds to the mounting of the struts as illustrated in FIGS. 7 and 9.
  • each strut can be positioned on demand, regardless of the position of others.
