Abstract
Description
La présente invention concerne le domaine du bâtiment, en particulier de la réalisation de charpentes, et a pour objet un tendeur perdu, en particulier pour assemblage de feuillards perforés de contreventement. The present invention relates to the building sector, in particular the production of frameworks, and relates to a lost tensioner, in particular for the assembly of perforated bracing strips.
Actuellement, le contreventement des fermes de charpentes s'effectue généralement au moyen de pièces de bois fixées sur lesdites fermes après mise en place de celles-ci. Currently, the bracing of structural trusses is generally carried out using pieces of wood fixed to said trusses after they have been put in place.
Cependant, un tel mode de contreventement de charpente ne permet pas une légèreté de construction et un faible encombrement. I1 existe également des procédés de contreventement par feuillards perforés, mais l'utilisation de ces derniers est limitée du fait d'une mise en oeuvre longue et difficile. However, such a method of bracing the frame does not allow a light construction and a small footprint. There are also methods of bracing with perforated strips, but the use of the latter is limited due to long and difficult implementation.
La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet un tendeur perdu, en particulier pour assemblage de feuillards perforés de contreventement, caractérisé en ce qu'il est essentiellement constitué par deux éléments en tôle avantageusement pliés en U, munis chacun à sa partie inférieure de tétons de section carrée ou rectangulaire obtenus par estampage, éventuellement, par deux contre-plaques munies chacune de trous de forme correspondante à la section des te tons, et coopérant avec chaque élément pour le maintien du feuillard correspondant, les totons traversant le feuillard et étant, soit repliés sur lui, soit tournés en hélice après passage dans les trous de la contre-plaque, et par un dispositif de mise sous tension des feuillards constitué par une vis de serrage à filetages inverses coopérant avec des écrous ou autres parties filetées prévues dans l'ame des éléments en U ou par un système à excentrique verrouillable. It has, in fact, for its object a lost tensioner, in particular for assembling perforated bracing strips, characterized in that it is essentially constituted by two sheet metal elements advantageously bent in a U shape, each provided at its lower part with nipples of square or rectangular section obtained by stamping, optionally, by two counter-plates each provided with holes of shape corresponding to the section of the tones, and cooperating with each element for the maintenance of the corresponding strip, the studs passing through the strip and being either folded back on it, either turned in a helix after passing through the holes in the counterplate, and by a device for tensioning the straps constituted by a clamping screw with reverse threads cooperating with nuts or other threaded parts provided in the core of U-shaped elements or by a locking eccentric system.
L'invention sera mieux comprise gracie à la description ci-apres, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel la figure I est une vue en plan d'un tendeur conforme à l'invention la figure 2 est une vue en élévation latérale d'un élément en U, et la figure 3 est une vue en plan d'une contre-plaque. The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which FIG. I is a view in plan view of a tensioner according to the invention, FIG. 2 is a side elevation view of a U-shaped element, and FIG. 3 is a plan view of a counterplate.
Conformément à l'invention, et comme le montre plus particulièrement, à titre d'exemple, la figure 1 du dessin annexé, le tendeur perdu, en particulier pour assemblage de feuillards de contreventement, est essentiellement constitué par deux éléments en tôle 1, qui sont avantageusement pliés en U, par exemple à ailes inégales, par deux contre-plaques 2 coopérant avec les éléments 1 pour le maintien des feuillards 3 correspondants, et par une vis de serrage 4 à filetages inverses coopérant avec des écrous 5, ou autres éléments filetés, prévus dans l'amie 6 des éléments en U 1. In accordance with the invention, and as shown more particularly, by way of example, FIG. 1 of the attached drawing, the lost tensioner, in particular for assembling bracing strips, is essentially constituted by two sheet metal elements 1, which are advantageously bent in a U, for example with uneven wings, by two counter-plates 2 cooperating with the elements 1 for holding the corresponding strips 3, and by a clamping screw 4 with reverse threads cooperating with nuts 5, or other elements threaded, provided in friend 6 of U-shaped elements 1.
Les éléments 1 sont munis chacun à sa partie inférieure de totons 7 de section carrée ou rectangulaire obtenus par estampage lors de la découpe desdits éléments 1 avant pliage. (figure 2). Ces totons 7 traversent les feuillards 3 correspondants grâce à des perçages 9 de ces derniers, et coopèrent avec des trous 8 de forme correspondante des contre-plaques 2, le maintien des contre-plaques étant obtenu par torsion en hélice des totons 7 après montage. The elements 1 are each provided at its lower part with studs 7 of square or rectangular section obtained by stamping during the cutting of said elements 1 before folding. (figure 2). These studs 7 pass through the corresponding strips 3 by means of holes 9 in the latter, and cooperate with holes 8 of corresponding shape of the counterplates 2, the retaining of the counterplates being obtained by helical torsion of the studs 7 after assembly.
Il est également possible de monter les éléments 1 sur les feuillards 3 sous les contre-plaques 2, les tetons étant alors simplement repliés après montage. It is also possible to mount the elements 1 on the strips 3 under the counter plates 2, the pins then being simply folded back after assembly.
La vis de serrage 4 à filetage inverse, qui coopère avec des écrous 5 solidaires des éléments en U1, est munie dans sa partie centrale d'un élément de manoeuvre 10, par exemple sous forme d'un écrou solidarisé par soudure, permettant son vissage dans les écrous 5, et aisni le serrage des éléments 1 ensemble avec les feuillards 3. The clamping screw 4 with reverse thread, which cooperates with nuts 5 integral with the U1 elements, is provided in its central part with an operating element 10, for example in the form of a nut secured by welding, allowing it to be screwed in the nuts 5, and aisni the tightening of the elements 1 together with the strips 3.
I1 est également possible de tendre les feuillards 3 en solidarisant les deux éléments avec un système de traction à excentrique verrouillable. It is also possible to tension the strips 3 by joining the two elements with a locking eccentric traction system.
Gracie à l'invention, il est possible de réaliser de manière simple et rapide une mise sous tension de feuillards de contreventement. Thanks to the invention, it is possible to quickly and simply tension the bracing strips.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing.
Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
