Description

L'invention se rapporte à des membrures constituant les éléments d'une structure spatiale portante.The invention relates to frames constituting the elements of a bearing spatial structure.

On connaît des structures spatiales telles qu'échafaudages, planchers, charpentes, dômes, etc. qui sont constituées par ses membrures tubulaires, fixées par exemple, par vissage axial sur des noeuds par l'intermédiaire d'une pièce ou embout soudé sur cette membrure et comportant un taraudage correspondant - voir par exemple FR 2 452 628 -. Cet embout peut avoir suivant le cas une forme cylindrique ou tronconique.Spatial structures are known such as scaffolding, floors, frames, domes, etc. which are constituted by its tubular members, fixed for example, by axial screwing on nodes by means of a part or end welded on this member and comprising a corresponding thread - see for example FR 2 452 628 -. This tip may have, depending on the case, a cylindrical or frustoconical shape.

Cette réalisation présente les inconvénients suivants :

  • les opérations de soudage de l'embout taraudé à l'extrémité des tubes sont délicates et ne peuvent pas en général être exécutées sur chantier, avec une fiabilité suffisante,
  • les dimensions de ces embouts, qui sont fonction des diamètres des tubes de membrure sont très variables ce qui exige un stock minimum pour réaliser tous les assemblages concernés,
  • la longueur des tubes doit être fixée à l'avance en fonction de la distance exacte des noeuds à relier, avant fixation des embouts.
This embodiment has the following drawbacks:
  • the welding operations of the threaded nozzle at the end of the tubes are delicate and generally cannot be carried out on site, with sufficient reliability,
  • the dimensions of these end fittings, which are a function of the diameters of the frame tubes, are very variable, which requires a minimum stock to carry out all of the assemblies concerned,
  • the length of the tubes must be fixed in advance according to the exact distance of the nodes to be connected, before fixing the end caps.

On connaît, par ailleurs, des structures spatiales constituées de membrures tubulaires de forme circulaire dont la fonction est de résister aux efforts longitudinaux de traction ou de compression (US 4 183 190).In addition, spatial structures are known which consist of tubular members of circular shape whose function is to resist longitudinal tensile or compressive forces (US 4,183,190).

Cependant, dans la plupart des utilisations pratiques, les membrures supportent en plus des efforts axiaux, des efforts de flexion, souvent dans une direction préférentielle (par exemple verticale dans le cas de la pesanteur). Les profils, généralement autres que circulaires, présentant une forme et un moment d'inertie adaptés aux efforts subits, en vue d'une économie de matière, sont donc généralement utilisés.However, in most practical uses, the members support in addition to the axial forces, bending forces, often in a preferred direction (for example vertical in the case of gravity). Profiles, generally other than circular, having a shape and a moment of inertia adapted to the sudden forces, with a view to saving material, are therefore generally used.

D'autre part, les liaisons de ces membrures sur les noeuds se font par l'intermédiaire d'une surface d'extrémité plane ou tout au moins d'une surface sphérique de projection égale à la section droite du tube cylindrique utilisé ; il en résulte un encombrement très important qui réduit le nombre et/ou la section unitaire des membrures utilisables, liées à un même noeud.On the other hand, the connections of these members on the nodes are made via a plane end surface or at least a spherical projection surface equal to the cross section of the cylindrical tube used; this results in a very large footprint which reduces the number and / or the unitary section of the usable members, linked to the same node.

La présente invention résout ces difficultés en utilisant des membrures dont la section droite de forme quelconque, comporte un canal circulaire central, et dont au moins une des extrémités est effilée, afin de dégager ledit canal central, par exemple selon une forme conique ou pyramidale. De cete façon, l'encombrement au voisinage des noeuds est limité, sans avoir recours à une pièce spécifique rapportée par soudage ou autre moyen de liaison, telle que celle décrite dans le FR 2 452 628.The present invention solves these difficulties by using members whose cross section of any shape, comprises a central circular channel, and at least one of the ends of which is tapered, in order to release said central channel, for example in a conical or pyramidal shape. In this way, the size in the vicinity of the nodes is limited, without having recourse to a specific piece added by welding or other connecting means, such as that described in FR 2 452 628.

Cette disposition facilite en outre le freinage de la vis axiale de fixation, une fois mise en place, par ovalisation du canal central de part et d'autre de celle-là, à l'aide d'une pince manuelle ou pneumatique, utilisable sur chantier, en exerçant une pression en deux zones diamétralement opposées de celui-ci.This arrangement also facilitates braking of the axial fixing screw, once put in place, by ovalization of the central channel on either side of it, using a manual or pneumatic clamp, usable on site, by exerting pressure in two diametrically opposite zones thereof.

Les membrures selon les revendications 1 et 2 peuvent également servir d'embouts de liaison à fixer dans un profilé tubulaire simple dont le profil intérieur est égal au profil extérieur de la membrure considérée ; ces embouts sont usinés en une forme effilée ; ils sont fixés dans le profilé tubulaire simple par soudage, collage ou tout autre moyen ; ce procédé est cependant mieux adapté aux structures préfabriquées en usine.The members according to claims 1 and 2 can also serve as connecting ends to be fixed in a simple tubular profile whose internal profile is equal to the external profile of the member considered; these tips are machined into a tapered shape; they are fixed in the simple tubular profile by welding, gluing or any other means; this process is however better suited to prefabricated structures in the factory.

L'invention sera mieux comprise à l'aide des exemples suivants.

  • La figure 1 représente une vue en bout des sections de diverses membrures selon l'invention, ne comportant qu'un canal central.
  • La figure 2 représente en perspective une membrure tubulaire dont la section droite est représentée à la figure 3.
  • La figure 4 représente une coupe axiale d'un embout de liaison réalisé avec les membrures selon l'invention et présentant une extrémité effilée selon l'invention.
  • La figure 1 représente diverses sections de membrures présentant un seul canal central (3). Dans le cas de la figure 3-1, les rainures longitudinales de la membrure (10) permettent la fixation de divers éléments de structure, tels que faux- plafonds, ou autres.
The invention will be better understood using the following examples.
  • Figure 1 shows an end view of the sections of various members according to the invention, comprising only a central channel.
  • FIG. 2 shows in perspective a tubular member whose cross section is shown in FIG. 3.
  • Figure 4 shows an axial section of a connecting end piece made with the members according to the invention and having a tapered end according to the invention.
  • Figure 1 shows various sections of members with a single central channel (3). In the case of Figure 3-1, the longitudinal grooves of the frame (10) allow the attachment of various structural elements, such as false ceilings, or others.

Les figures 2 et 3 représentent une membrure suivant l'invention, présentant un canal axial (3) relié à la forme tubulaire extérieure cylindrique (5) par quatre ailettes (6). L'extrémité de celle-ci a été chanfreinée en cône de manière à dégager le canal central (3). De ce fait, la membrure présente d'une part une surface frontale réduite et d'autre part, cela permet le freinage de la vis de fixation, une fois en place, en exerçant les efforts représentés par les flèches.Figures 2 and 3 show a frame according to the invention, having an axial channel (3) connected to the cylindrical outer tubular form (5) by four fins (6). The end of the latter has been chamfered in a cone so as to release the central channel (3). Therefore, the frame has on the one hand a reduced front surface and on the other hand, it allows the braking of the fixing screw, once in place, by exerting the forces represented by the arrows.

La figure 4 représente un embout de liaison effilé (a) réalisé par prélèvement de la partie (a) de la membrure (2) - figure 2 - qui est fixé à l'extrémité d'un tube cylindrique circulaire (7) par le cordon de soudure (8).FIG. 4 represents a tapered connecting end piece (a) produced by removing the part (a) of the frame (2) - FIG. 2 - which is fixed to the end of a circular cylindrical tube (7) by the cord solder (8).
