Abstract

The scaffolding has risers (5) each with a cup shaped housing (6) at each end that take short vertical tube extensions from the ends of cross braces (11). Each cross brace has two struts (10, 12) attached to it to form a triangle, the apex of which fits into a socket joint (14) in the underside of the brace above. The scaffolding has adjustable feet (7) at the bottom, screw jacks (8) at the top, and when dismantled can be stored and transported easily as the largest single part of the assembly is the brace triangle.

Description

La présente invention a pour objet un échafaudage démontable qui est tout particulièrement étudié en vue d'être utilisé pour soutenir des coffrages, notamment des coffrages pour couler des éléments en beton, en béton armé ou en matière analogue, mais dont la conception permet un démontage rapide sans outil en éléments simples facilitant le transport et le stockage. The present invention relates to a removable scaffolding which is very particularly studied with a view to being used to support formwork, in particular formwork for pouring elements of concrete, reinforced concrete or similar material, but whose design allows disassembly fast without tools in simple elements facilitating transport and storage.

On connaît déja des échafaudages démontables du type mentionné ci-dessus mais tous présentent l'inconvénient de ne pouvoir être aisément démontés sans l'emploi d'outils et de plus, une fois en partie démontés, les éléments de base présentent un volume trop important pour rendre facile leur stockage et leur transport. There are already known demountable scaffolds of the type mentioned above but all have the drawback of not being able to be easily dismantled without the use of tools and moreover, once partly dismantled, the basic elements have too large a volume. to make storage and transport easy.

La présente invention remédie à ces inconvénients en créant un échafaudage démontable qui est essentiellement constitué par des éléments rectilignes formant partie de montants et des contreventements, réalisés d'une manière très simple, peu volumineux, qui peuvent être fixés sur des organes de maintien solidaires des montants sans l'utilisa- tion d'outils. Ainsi, on peut facilement monter et démonter ces échafaudages, ce travail pouvant être effectué, par une main-d'oeuvre non spécialisée, d'une manière sûre et rapide sans aucun risque d'accident. The present invention overcomes these drawbacks by creating a demountable scaffolding which is essentially constituted by rectilinear elements forming part of uprights and braces, made in a very simple manner, not very bulky, which can be fixed on holding members integral with the uprights without the use of tools. Thus, one can easily assemble and disassemble these scaffolding, this work being able to be carried out, by an unskilled labor, in a safe and fast manner without any risk of accident.

Conformément à l'invention, l'échafaudage démontable est constitué par au moins deux montants verticaux réalisés par des éléments s'emmanchant les uns dans les autres et comportant, de distance en distance, des gorges circulaires destinées à recevoir des pièces solidaires des extrémités des contreventements. According to the invention, the removable scaffolding is constituted by at least two vertical uprights produced by elements which fit into one another and comprising, from distance to distance, circular grooves intended to receive parts integral with the ends of the braces.

Suivant une autre particularité de l'invention, les contreventements qui affectent une forme quelconque sont fixés, d'une part, sur les gorges circulaires et, d'autre part, sur les montants par des moyens divers. According to another particular feature of the invention, the braces which affect any shape are fixed, on the one hand, on the circular grooves and, on the other hand, on the uprights by various means.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées; à titre d'exemples, aux dessins annexés. Embodiments of the object of the invention are shown; by way of examples, to the accompanying drawings.

La fig. 1 est une vue en perspective d'un échafauda dage démontable réalisé à partir des éléments de l'invention. Fig. 1 is a perspective view of a removable scaffolding made from the elements of the invention.

La fig. 2 est une vue en perspective, partie en coupe, à plus grande échelle, d'un élément de la fig. 1. Fig. 2 is a perspective view, partly in section, on a larger scale, of an element of FIG. 1.

Les fig. 3, 4, 5, 6 et 7 montrent diverses possibilités de réalisation de contreventements. Figs. 3, 4, 5, 6 and 7 show various possibilities for making bracing.

La fig. 8 montre, en élévation latérale, la réalisation d'un autre échafaudage à partir d'un contreventement particulier. Fig. 8 shows, in side elevation, the making of another scaffolding from a particular bracing.

La fig. 9 est une coupe sensiblement suivant la ligne IX-IX de la fig. 8. Fig. 9 is a section substantially along the line IX-IX of FIG. 8.

A la fig. 1, on a représenté un échafaudage démontable plus spécialement dénommé "tour" et utilisé pour le soutènement de coffres de moulage tels que ceux employés pour la réalisation de constructions en béton armé. Comme on peut s'en rendre compte, pour cette figure, l'échafaudage est constitué par des montants verticaux 1, 2, 3 et 4 réalisés chacun par des éléments tubulaires 5 de longueur standard présentant à chacune de leurs extrémités des coupelles 6 (voir fig. 1 et 2) dans lesquelles peuvent pénétrer les extrémités 5a des tubes 5 pour les coupelles supérieures 6 tandis que les coupelles inférieures 6 sont placées audessus de l'extrémité inférieure 5a des tubes 5. In fig. 1, there is shown a removable scaffolding more especially called "tower" and used for the support of molding boxes such as those used for the realization of reinforced concrete constructions. As can be seen, for this figure, the scaffolding is constituted by vertical uprights 1, 2, 3 and 4 each made by tubular elements 5 of standard length having at each of their ends cups 6 (see Fig. 1 and 2) into which the ends 5a of the tubes 5 can penetrate for the upper cups 6 while the lower cups 6 are placed above the lower end 5a of the tubes 5.

Dans le cas de la fig. 1, on se trouve en présence de montants qui sont réalisés par trois tubes 5 emboîtés les uns dans les autres, les tubes inférieurs 5 étant supportés par des pieds 7 réglables en hauteur. Ces pieds sont connus en eux-mêmes. De plus, les montants 1, 2, 3, 4 et 5 se terminent, à leur partie supérieure, par des vérins 8 également connus en eux-mêmes. In the case of fig. 1, we are in the presence of uprights which are produced by three tubes 5 nested one inside the other, the lower tubes 5 being supported by feet 7 adjustable in height. These feet are known in themselves. In addition, the uprights 1, 2, 3, 4 and 5 end, at their upper part, by jacks 8 also known in themselves.

Les contreventements 10 sont, dans le cas de la fig. 1, réalisés par des traverses horizontales ll solidaires de jambes de force 12, 13 formant sensiblement avec chaque traverse inférieure 11 un triangle et la pointe de ce triangle comporte un élément de jonction 14 des jambes de force 12, 13. En outre, l'organe de jonction 14 peut présenter un téton vertical pénétrant dans un trou borgne percé dans la traverse 11 du contreventement supérieur. The braces 10 are, in the case of FIG. 1, produced by horizontal crosspieces ll integral with struts 12, 13 forming substantially with each lower cross member 11 a triangle and the tip of this triangle comprises a junction element 14 of the struts 12, 13. In addition, the junction member 14 may have a vertical stud penetrating a blind hole drilled in the cross member 11 of the upper bracing.

On obtient ainsi une tour très légère qui peut être démontée en éléments de tout petit volume car l'élément de plus grand volume est constitué par une traverse 11 et les deux jambes de force 12, 13 réunies à leur partie superieure par l'organe de jonction 14. A very light tower is thus obtained which can be disassembled into elements of very small volume because the element of larger volume consists of a cross member 11 and the two struts 12, 13 joined at their upper part by the member of junction 14.

Comme cela est connu depuis fort longtemps, les extrémités des traverses 11 comportent des pattes verticales lla qui pénètrent aisément dans les coupelles 6 supérieures et inférieures comme cela est visible à la fig 2. As has been known for a very long time, the ends of the crosspieces 11 have vertical tabs lla which easily penetrate into the upper and lower cups 6 as can be seen in FIG. 2.

Bien entendu, certaines tours peuvent ne comporter que trois montants convenablement contreventes par ceux déjà décrits (contreventement 10) soit par des barres 20 horizontales (voir fig. 3) des contreventements 21 (voir fig. 4) en croix de Saint-André, soit par des contreventements en triangle isocèle 22 (voir fig. 5) avec à la partie supérieure une traverse complémentaire llb fixe ou amovible, en triangle quelconque 23 (voir fig. 6), soit par des contreventements 24 en Z (voir fig. 7). Of course, some towers may have only three uprights suitably braced by those already described (bracing 10) or by horizontal bars 20 (see fig. 3) bracing 21 (see fig. 4) in Saint Andrew cross, or by isosceles triangle braces 22 (see fig. 5) with a complementary or fixed additional cross member llb at the top, in any triangle 23 (see fig. 6), or by Z-shaped braces 24 (see fig. 7) .

I1 est également possible, sur les montants 30 réalisés de la façon décrite ci-dessus, de fixer des traverses horizontales 31 par des pattes solidaires de leurs extrémités et pénétrant dans les coupelles 6 mais également d'ajouter des contreventements réalisés par des croix de Saint
André 33 fixées à l'une de leurs extrémités sur la traverse supérieure 31 reliée ensuite aux montants 30 par des pièces d'accrochage 35 en L passant autour de ceux-ci et comportant des parties filetées d'extrémité 35a sur lesquelles viennent se fixer les extrémités des profilés formant la croix de
Saint-André 33. I1 est à signaler que les contreventements en Croix de Saint-André 33 sont reliés en leur centre (point 37) par tout moyen convenable. Ce dernier montage permet de maintenir correctement les contreventements qui, ainsi, travaillent à de grandes distances sur les montants 30, ces contreventements en croix de Saint-André pouvant être renforcés par des contreventements 40 en Z du type de la fig. 7.
It is also possible, on the uprights 30 produced in the manner described above, to fix horizontal crosspieces 31 by lugs integral with their ends and penetrating into the cups 6 but also to add bracing made by Saint crosses
André 33 fixed at one of their ends on the upper cross member 31 then connected to the uprights 30 by latching pieces 35 in L passing around them and comprising threaded end portions 35a on which are fixed the ends of the profiles forming the cross of
Saint-André 33. It should be noted that the cross-bracing of Saint-André 33 is connected at their center (point 37) by any suitable means. This last assembly makes it possible to correctly maintain the braces which, thus, work at great distances on the uprights 30, these bracing in cross of Saint-André being able to be reinforced by bracing 40 in Z of the type of fig. 7.

De tels échafaudages permettent, grâce aux pieds réglables 7 constitués par des vérins hydrauliques ou mécaniques, d'obtenir une course de réglage très suffisante qui évite le démontage complet de l'échafaudage dans le cas de son utilisation dans des endroits divers. Such scaffolding makes it possible, thanks to the adjustable feet 7 constituted by hydraulic or mechanical jacks, to obtain a very sufficient adjustment stroke which avoids the complete dismantling of the scaffolding in the case of its use in various places.

L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the embodiments shown and described in detail, since various modifications can be made thereto without departing from its scope.
