Definitions
- FR-A-1 315 671 describes a triangulated scaffolding element allowing, by fitting the male mounting fittings into the female fittings, the production of robust and stable scaffolding, in particular in the industrialized form in which a pin locks the fitting of each pair of two male-female fittings.
- the complementary tubes have sufficient sections to support the loads to be supported.
- the male end pieces have a narrowed lower section, and in any case have a normal section smaller than that of the vertical tubes of the triangulated elements into which they are introduced, so that it becomes impossible, without modifications, to use the corresponding scaffolding.
- the practically used interlocking locking pins passing through the interlocking fittings also constitute obstacles to the adaptation of the complementary adjustment tubes.
- the object of the invention is to propose a modification of these triangulated elements in order, while retaining the principle of construction of a scaffold by means of such triangulated elements, substantially all of the same model for a determined scaffold, allowing adaptation of the aforementioned upper complementary tubes and thus obtain the desired adjustment.
- the invention therefore relates to a scaffolding constituted by the assembly of a plurality of triangulated elements, each of them comprising a vertical hollow tube having two ends, a first of these two ends being provided with a male connector d 'fitting and the second of these ends being provided with a female fitting fitting; a substantially horizontal tube having two ends, a first of these two ends of the substantially horizontal tube being fixed on the vertical tube in the vicinity of one of the two said ends of this vertical tube and the second of the two ends of the substantially horizontal tube being provided with '' a female immobilization fitting, and, an oblique tube for connecting said vertical and substantially horizontal tubes, fixed on these said tubes, while the male fitting fitting the vertical tube of a first triangulated element is capable of being introduced concomitantly, first in the female fitting for immobilizing the substantially horizontal tube of a second triangulated element, then in the female fitting fitting the vertical tube of a third triangulated element, in order, on the one hand, to produce the mounting in alignment of the vertical tubes
- the male fitting fitting of the vertical tube of a triangulated element is hollow and has an internal diameter at least equal to that of said vertical tube
- the lock is constituted by a "bayonet" mounting "of two latch elements opening one into the external surface of the male interlocking fitting, the other into the internal surface of the female interlocking fitting of each vertical tube, so that an outer diameter tube slightly smaller than the inner diameter of the vertical tubes of the triangulated elements can slide freely inside two adjacent vertical tubes assembled from triangulated elements without being hampered by said latch.
- the male fitting fitting of the vertical tube of a triangulated element is constituted by the first end itself of said vertical tube;
- the female fitting fitting of the vertical tube of a triangulated element is constituted by a sleeve which has an inside diameter greater than the outside diameter of the second end of said vertical tube and which is fixed to this second end of the vertical tube;
- the element of the "bayonet" lock secured to the male fitting connector is constituted by the male element of this "bayonet” lock and cooperates with the female element of said latch, which is constituted by a groove formed in the thickness of said sleeve, the part of the sleeve delimited by two transverse sections between which is located said groove being preferably reinforced by an external ring;
- the main advantage of the invention is functional: while retaining the principle of using triangulated elements, appreciated for their robustness and the simplicity of the assemblies, it has become possible, with the new triangulated elements, to carry out all of the desired size settings.
- FIGS. 1 and 9 intends to retain the use of triangulated elements for the construction of scaffolding.
- an element represented in FIGS. 1 and 9, comprises: - A vertical hollow tube 1, whose internal section has a substantially constant diameter D1, and which has a first end 2, constituting a male fitting connector, and a second end 3, constituting a female fitting connector; - a substantially horizontal tube 4, a first end 5 of which is fixed to the external part of the second end 3 (female connector) of the vertical tube, and the second end of which 6 is constituted by a bent flat iron, having a horizontal wing 7 , provided with an orifice 8 forming immobilization fitting; - an oblique tube 9, for connecting said vertical 1 and substantially horizontal tubes 4, fixed, on the one hand, near the first end 2 (male interlocking connector) of the vertical tube, on the other hand, on a wing vertical 10 which comprises the second end 6 of the substantially horizontal tube 4.
- the male fitting connector 2 of a vertical tube 1 is constituted by the section of the lower end of said vertical tube 1, delimited by the lower end cross section 11 of the tube.
- This section is surrounded from a D12 of said cross-section distance 11, by a first sleeve 12 fitted to the outer face 1a of this part of the tube 1 in the lower part of which has been cut the male member 13 a bayonet type locking bolt.
- This first sheath 12 has its upper part (above the male element 13 which remains free) surrounded by a second sheath 14, delimited by its section extreme lower transverse 15.
- the female fitting connector 3 of a vertical tube 1 is constituted by the section of the upper end of said vertical tube 1, delimited by the upper extreme cross section 16 of said vertical tube.
- This section is surrounded by a first sheath 17, which exceeds said cross section 16, which is notched with a notch 18 constituting the female element of said nesting lock of the "bayonet" type and which is finally delimited by a cross section upper 19.
- the upper part of this first sheath 17 is surrounded, from a cross section 24 located below the notch 18, and in the region of this notch 18, by a second sheath 20, intended to mask said notch and to reinforce the first sheath 17 in the region of the notch, and delimited by an upper cross section 21.
- FIG. 9 represents the assembly of the vertical tube 1 of a first upper triangulated element A, with the immobilization fitting 8 (constituted by an orifice) of a second intermediate triangulated element B and with the vertical tube 1 of third lower triangulated element C.
- These triangulated elements are represented just before and after assembly in FIGS. 5 and 6. The following points can be noted, with reference to FIG.
- the alignment of the vertical tubes 1 of the two triangulated upper A and lower C elements (common axis 22) and the absence of prominence inside said tubes (in particular the absence of a locking pin) makes it possible to freely pass a tube 23 of outside diameter D23 slightly smaller than the inside diameter D1 of the vertical tubes 1;
- the upper cross sections 19 and 21 of the first and second sleeves located at the upper part of a vertical tube 1 are located substantially in the same plane P (perpendicular to the axis 22) of the vertical tubes 1); - As shown in Figure 1, the plane P of the upper cross sections 19 and 21 of the upper end of the vertical tube 1 of a triangulated element contains also substantially the lower face 7b of the second end 6 of the substantially horizontal tube 4 of the same triangulated element; -
- the underside 7b of the wing 7 of the triangulated intermediate element B rests on the upper cross section 21 of the sheath 20 ( Figure 9); the internal diameters of the sleeves 17 and 20 are slightly greater than the external diameters of the sleeves 12
- FIGS. 2A, 2B, 3A, 3B and 4A, 4B show three configurations that the substantially horizontal tubes 4 of the upper A and lower C triangular elements can take, the male interlocking fitting of the vertical tube of one being introduced into the female fitting of the vertical tube on the other, the axes 22 of the two vertical tubes being combined.
- Figures 2A, 2B first show the configuration for introducing the male element 13 of the latch into the female groove 18 of said latch, the substantially horizontal tube 4 of the upper triangulated element A being offset by a rotation R1 in a first direction S1 relative to the substantially horizontal tube of the lower triangulated element C.
- the upper triangulated element A can be mounted on the lower triangulated element C as well as being separated from this lower triangulated element C.
- Figures 3A, 3B show the configuration of the final assembly, as illustrated in Figure 6.
- the angular offset R1 has been removed, compared to the previous configuration of Figure 2A, by a rotation R1 of the upper triangulated element A in the opposite direction to the direction S1.
- the two substantially horizontal arms are superimposed (seen from above), and the male element 13 of the latch of the upper triangulated element A cooperates with the lower part of the notch 18 of the lower triangulated element C to prevent any disengagement of the vertical tube of one relative to the vertical tube of the other triangulated element.
- FIGS. 4A, 4B represent a configuration in which, beyond that of FIGS. 3A, 3B, the upper triangulated element A has undergone a new rotation R2, in the direction S2 opposite to S1. This rotation allows the mounting of a triangulated element according to the upper triangulated element A considered, next element located at the same height as the element A (at the upper end of the rightmost vertical tube of Figures 5 and 6) .
- Figures 5 and 6 show the quite conventional presence of screw jacks 24 of foot for the support of the columns of vertical tubes 1 superimposed. Note that, in these figures, the scaffolding shown has a square or a diamond as a base, but that the provisions of the invention apply to all other types scaffolding with a polygonal base (five, six sides, or more, or even three sides).
- Figures 7 and 8 show the upper part of a scaffolding according to the invention.
- last isolated vertical tubes 23, not included in non-deformable triangles should be noted, associated of course with other horizontal 25 and oblique tubes 26 (of adjustable lengths) allowing the various triangulations to be completed.
- These vertical tubes 23 are capable of sliding inside the one or two last vertical tubes 1 of the columns of such superposed tubes, in the manner shown in FIG. 9.
- These tubes 23 are provided with several tansversal holes 27, regularly spaced, which allow the height adjustment by means of pins 28 introduced concomitantly into the orifices of a particular mounting element 29, described with reference to FIG. 10, and of a pair of said holes 27 of each tube 23.
- screw jacks 30 are adapted to the upper part of each vertical tube 23 to adjust the total support height of the scaffolding with precision.
- FIGS. 7 and 8 show the same part of scaffolding before assembly, the various elements being presented for assembly, and, after assembly.
- the mounting element 29 is shown in FIG. 10. It consists of two half-shells 31, of generally cylindrical shape, articulated by an axis 32, around adjacent edges 33, and which, once closed, are capable of perform the same function as that of the male fitting connector 2 of a vertical tube 1.
- This mounting element 29 can be fixed at any desired height along a tube 23, because each of its shells is provided with a hole 34, which in cooperation with a pair of holes 27 of the tube 23 and of the pin 28, effectively allows said fixing of the mounting element 29 on the tube 23.
- a male latch element 13A similar to element 13, equips at least one of the shells 31 and allows the tube 23 to be locked on the upper end of the last vertical element tube 1 triangular monoblock.
- the advantage of this particular mounting element 29 is that it can be dismantled independently of the tube 23 on which it is mounted, by simple removal of the pin 28, unlocking of the lock 13A, sliding along the tube 23 and opening of the shells 31, and, after this dismantling of the element 29, the sliding of the tube 23 inside the vertical tube or tubes 1 of the triangulated elements.
- Figure 11 shows an alternative assembly of two vertical tubes 1 of triangulated elements.
- the upper end of the lower tube widens into a collar 35, in the internal face of which two grooves 36 are formed.
- the end of the substantially horizontal tube 4 is shaped like a U, the upper branch 37 of which is provided with the orifice 8 forming an immobilizing connector, and adapts to the upper end face of the collar 35, while the lower leg 38 of the U has an opening 39 allowing it to pass a vertical tube 1, but to be blocked under the lower face 40 of collar 35.
- two pins 41 secured to the end lower of the vertical tube 1 upper extend transversely, towards the outside, from the external face of said tube 1, and can cooperate with the grooves 36 to ensure the mounting, and the locking in the mounted position of the three parts: the two vertical tubes 1 and the substantially horizontal tube 4.
- the arrangements in accordance with the invention allow free sliding, inside vertical tubes 1 of triangulated elements, of complementary vertical tubes 23 with external diameters very little less than their internal diameter, therefore without excessive weakening of the supporting structure, and as long as necessary to obtain a desired height adjustment and good guidance in the tubes 1.
- the definition of the locks used makes it possible to obtain extreme configurations which are safety configurations, since the pivoting deflections of the upper triangulated element are limited there, this upper triangulated element also providing support for an edifying fitter. scaffolding.
