Description

La présente invention concerne une toiture autoportante, en particulier pour bâtiments industriels, formée d'éléments modulaires de grande portée, conformément au préambule de la revendication 1.The present invention relates to a self-supporting roof, in particular for industrial buildings, formed of modular elements of large span, in accordance with the preamble of claim 1.

Il est connu du FR-A-1 558 925 d'utiliser des éléments de toiture modulaires à plans obliques comprenant une coque ou paroi extérieure autoportante conférant la résistance mécanique à l'élément, une couche d'isolation thermique et une paroi intérieure supportant la couche d'isolation et portée par la paroi extérieure, celle-ci étant en outre raidie par des éléments métalliques, tels que des fers "oméga" soudés à la coque. Les éléments de toiture sont préfabriqués en usine, le travail restant à faire sur le chantier consistant essentiellement à mettre en place les éléments et à les assembler pour former la toiture totale.It is known from FR-A-1 558 925 to use modular roof elements with oblique planes comprising a self-supporting outer shell or wall conferring mechanical resistance to the element, a layer of thermal insulation and an inner wall supporting the insulation layer and carried by the outer wall, the latter being further stiffened by metallic elements, such as "omega" irons welded to the shell. The roof elements are prefabricated in the factory, the work remaining to be done on the site essentially consists of putting the elements in place and assembling them to form the total roof.

Le FR-A-2 147 866 décrit une toiture du même type que celle du FR-A-1 558 925 en précisant qu'elle est composés d'éléments longitudinaux reposant sur une structure horizontale et constitués chacun par une coque en V renversée, et de cadres raidisseurs transversaux pliés de manière à présenter une géométrie congruente à la section droite de la coque.FR-A-2 147 866 describes a roof of the same type as that of FR-A-1 558 925, specifying that it is composed of longitudinal elements resting on a horizontal structure and each consisting of an inverted V hull, and transverse stiffening frames folded so as to have a geometry congruent to the cross section of the shell.

Le FR-A-1 494 733 décrit un élément de structure autoportante comprenant deux tôles nervurées disposées face à face et réunies entre elles par des baguettes isolantes. La toiture ainsi réalisée peut être plane ou composée de voûtes.FR-A-1 494 733 describes a self-supporting structural element comprising two ribbed sheets placed face to face and joined together by insulating rods. The roof thus produced can be flat or composed of vaults.

Le DE-A-2 609 405 décrit un élément de toiture en forme de gouttière, qui se comporte d'une manière analogue à celle d'une poutre en caisson sollicitée en flexion et comportant une série de raidisseurs internes formés par un seul profilé plein disposés transversalement entre les deux parois et liés rigidement à ces dernières.DE-A-2 609 405 describes a roofing element in the shape of a gutter, which behaves in a manner similar to that of a box beam subjected to bending and comprising a series of internal stiffeners formed by a single solid profile arranged transversely between the two walls and rigidly linked to the latter.

L'invention vise précisément à augmenter le moment fléchissant supportable par la toiture et à réduire le poids mort à supporter tout en réduisant l'existence de pont thermique au niveau des raidisseurs entre les deux parois intérieure et extérieure.The invention aims precisely to increase the bending moment which can be supported by the roof and to reduce the dead weight to bear while reducing the existence of thermal bridge at the level of the stiffeners between the two inner and outer walls.

A cet effet, il est prévu, conformément à l'invention que la section des éléments modulaires étant en forme de voûte renversée, les extrémités des raidisseurs sont ainsi fixées aux barres de compression que les raidisseurs sont constitués par deux fers ou deux profilés écartés l'un de l'autre et fixés chacun respectivement aux parois intérieure et extérieure et que des pièces d'entretoisement sont fixées par intervalles le long de chaque raidisseur entre lesdits profiles, de façon à empêcher la formation d'un pont thermique continu entre ceux-ci.To this end, it is provided, in accordance with the invention, that the section of the modular elements being in the form of an inverted vault, the ends of the stiffeners are thus fixed to the compression bars that the stiffeners are constituted by two irons or two spaced apart profiles l 'from each other and each fixed respectively to the inner and outer walls and that bracing pieces are fixed at intervals along each stiffener between said profiles, so as to prevent the formation of a continuous thermal bridge between them this.

L'association ainsi réalisée des deux parois, de leurs raidisseurs, des barres de sollicitation et de l'isolant intérieur, conduit à une structure unitaire autoportante qui ne se retrouve pas dans les documents cités plus haut et qui assure une bonne répartition des efforts d'une paroi à l'autre, donc fait participer la paroi intérieure à la résistance d'ensemble de l'élément de toiture tout en assurant une bonne coupure thermique entre les parois, même au niveau des raidisseurs.The combination thus produced of the two walls, of their stiffeners, of the stress bars and of the interior insulation, leads to a self-supporting unitary structure which is not found in the documents cited above and which ensures a good distribution of the forces of 'one wall to another, therefore involves the inner wall in the overall resistance of the roofing element while ensuring good thermal break between the walls, even at the stiffeners.

Les éléments de toiture selon l'invention présentent la forme d'une voûte, les parois étant formées par exemple de tôles nervurées cintrées.The roofing elements according to the invention have the shape of a vault, the walls being formed for example of curved ribbed sheets.

Les caractéristiques des revendications 2 et 3 concernent de mode préférentiels de réalisation de raidisseurs. L'invention sera bien comprise à la lecture de la description suivante, faite en référence aux dessins annexés. Dans les dessins:

On a représenté à la figure 1 deux éléments 1 d'une toiture autoportante pour bâtiment industriel.FIG. 1 shows two elements 1 of a freestanding roof for an industrial building.

Chaque élément a en section une forme sensiblement semicirculaire ouverte vers le haut, avec une largeur qui peut être d'environ 2 mètres, et peut avoir une longueur allant jusqu'à 30 mètres. Les éléments sont supportés à leurs extrémités par des appuis symbolisés en A, qui peuvent être constitués par les murs de façade du bâtiment.Each element has in section a substantially semicircular shape open upwards, with a width which can be around 2 meters, and can have a length of up to 30 meters. The elements are supported at their ends by supports symbolized in A, which can be constituted by the front walls of the building.

Chaque élément, comprend une paroi extérieure 2 et une pardi intérieure 3 cintrée de façon identique et de même résistance mécanique. Entre ces parois sont disposés, à intervalles réguliers dans le sens longitudinal, des raidisseurs transversaux épousant la forme des parois (voir la figure 5 pour cette disposition) et dont l'un est représenté en coupe à la figure 2 et à la figure 6.Each element comprises an exterior wall 2 and an interior wall 3 curved in an identical manner and with the same mechanical strength. Between these walls are arranged, at regular intervals in the longitudinal direction, transverse stiffeners conforming to the shape of the walls (see FIG. 5 for this arrangement) and one of which is shown in section in FIG. 2 and in FIG. 6.

On a représenté à la figure 2 une variante dans, laquelle deux fers 10, 11 ayant des ailes écartées forment le raidisseur 4; ils sont fixés respectivement aux parois 2 et 3, et entre les fers 10 et 11 sont placés à intervalles réguliers des pièces d'entretoisement formées par des tampons 12 en matière rigide thermiquement isolante, par exemple en bois ou en matière plastique rigide. La liaison entre les fers 10 et 11 est assurée par des pièces de serrage 13, 14 enserrant respectivement les tampons 12 et reliées par blocage d'un écrou 15 sur un boulon 16.There is shown in Figure 2 a variant in which two irons 10, 11 having spread wings form the stiffener 4; they are fixed respectively to the walls 2 and 3, and between the irons 10 and 11 are placed at regular intervals bracing pieces formed by pads 12 of rigid thermally insulating material, for example wood or rigid plastic material. The connection between the bars 10 and 11 is ensured by clamping pieces 13, 14 respectively enclosing the pads 12 and connected by blocking a nut 15 on a bolt 16.

Les parois 2 et 3 sont, dans la réalisation de la figure 1 constituées de bacs en acier, c'est-à-dire de tôles d'acier nervurées. Ces bacs se trouvent dans le commerce et chaque paroi sera formée d'un ou plusieurs de ces bacs, suivant la largeur requise. Si une paroi comprend plusieurs bacs, la liaison sera obtenue par recouvrement des ondes (ou nervures) et fixation par vis.The walls 2 and 3 are, in the embodiment of Figure 1 made of steel tanks, that is to say of ribbed steel sheets. These containers are commercially available and each wall will be formed from one or more of these containers, depending on the required width. If a wall comprises several tanks, the connection will be obtained by covering the waves (or ribs) and fixing by screws.

Pour renforcer la résistance aux sollicitations longitudinales des parties d'extrémité de l'élément de toiture on prévoit, comme le montre la figure 3, des profilés longitudinaux 17 logés dans la dernière onde de la paroi extérieure 2, et de même des profilés longitudinaux 18 logés dans la dernière onde de la paroi intérieure 3. Chacun de ces profilés constituent des banes qui travaillent en compression, puisque la voûte est ouverte vers le haut. Chaque profilé est placé entre deux raidisseurs 4 consécutifs et est fixé par ses extrémités sur des platines 19 soudées sur les raidisseurs 4.To strengthen the resistance to longitudinal stresses of the end parts of the roofing element, as shown in FIG. 3, longitudinal profiles 17 are provided, housed in the last wave of the outer wall 2, and likewise longitudinal profiles 18 housed in the last wave of the inner wall 3. Each of these sections constitute strips which work in compression, since the vault is open upwards. Each profile is placed between two consecutive stiffeners 4 and is fixed by its ends on plates 19 welded to the stiffeners 4.

Entre deux éléments de toiture adjacents sont disposées des barres de liaison 20 formant entretoises, qui sont fixées sur les extrémités découvertes des raidisseurs 4. Audessus des barres de liaison 20 est placé un faîtage étanche 21, et sous les barres 20 se trouve un sous-plafond 22 supporté par la face supérieure des banes longitudinales de compression 18 en vis-à- vis. Une couche d'isolant thermique 23 est posée sur le sous-plafond 22.Between two adjacent roofing elements are placed connecting bars 20 forming spacers, which are fixed to the exposed ends of the stiffeners 4. Above the connecting bars 20 is placed a watertight ridge 21, and under the bars 20 is a sub- ceiling 22 supported by the upper face of the longitudinal compression strips 18 opposite. A layer of thermal insulation 23 is placed on the sub-ceiling 22.

Un simple lanterneau translucide pourrait également être placé entre deux éléments de toiture adjacents.A simple translucent skylight could also be placed between two adjacent roof elements.

Les avantages de la toiture selon l'invention sont les suivants.The advantages of the roof according to the invention are as follows.

Grâce à la liaison rigide établie entre les parois intérieure et extérieure par les raidisseurs 4, et '"' les banes longitudinales de compression, la intérieure 3 contribue par sa résistance . à la rigidité de la toiture, au lieu de former mort que la paroi extérieure doitThanks to the rigid connection established between the interior and exterior walls by the stiffeners 4, and "" 'the longitudinal compression strips, the interior 3 contributes by its resistance to the rigidity of the roof, instead of forming dead as the wall exterior must

.'mr, comme dans l'état de la technique mentionné plus haut. Cela permet d'augmenter la portée d'un élément ou, pour une portée donnée, de réduire l'épaisseur des parois..'mr, as in the state of the art mentioned above. This makes it possible to increase the range of an element or, for a given range, to reduce the thickness of the walls.

D'autre part, les éléments de toiture 1 sont préfabriqués en usine et les seules opérations restant à effectuer sur le chantier sont la mise en place des éléments 1 sur les murs d'appui et la pose des barres de liaison, du faîtage, etc., entre les éléments 1.On the other hand, the roof elements 1 are prefabricated in the factory and the only operations remaining to be carried out on the site are the installation of the elements 1 on the support walls and the installation of the connecting bars, the ridge, etc. ., between elements 1.

On a représenté à la figure 4 une variante de réalisation dans laquelle il est prévu deux banes longitudinales de compression constitués par des tubes de section carrée 25, 26 s'étendant de façon continue sur toute la longueur de l'élément de toiture, au lieu d'être placés entre les raidisseurs dans les ondes des parois, comme représenté à la figure 3 Dans cette variante, tous les raidisseur 27 ont leurs extrémités fixées respectivement aux tubes 25, 26.There is shown in Figure 4 an alternative embodiment in which there are provided two longitudinal compression strips formed by tubes of square section 25, 26 extending continuously over the entire length of the roofing element, instead to be placed between the stiffeners in the waves of the walls, as shown in FIG. 3 In this variant, all the stiffeners 27 have their ends fixed respectively to the tubes 25, 26.

Une telle variante renforce le rôle de transmission des efforts entre les parois joué par les profilés de compression. Les profilés 25, 26 sont par ailleurs, remplis d'une mousse d'isolation thermique formée en place.Such a variant reinforces the role of transmission of forces between the walls played by the compression profiles. The sections 25, 26 are moreover filled with a thermal insulation foam formed in place.

Les raidisseurs ont également une structure différente de ce qu'on a décrit précédemment. Ils sont formés chacun de deux profilés en T 28a, 28b fixés respectivement à la paroi extérieure et à la paroi intérieure, de préférence au moyen de vis autotaraudeuses, non représentées. Les profilés 28a, 28b sont écartés et réunis par intervalles par des pièces d'entretoisement constituées par des plaques métalliques 29 soudées sur les âmes des profilés 28a, 28b. Une telle réalisation présente l'avantage d'une grande simplicité de réalisation et assure une coupure thermique entre parois très satisfaisante, sur toute la longeur du raidisseur 27.The stiffeners also have a different structure from what has been described above. They are each formed of two T sections 28a, 28b fixed respectively to the outer wall and to the inner wall, preferably by means of self-tapping screws, not shown. The sections 28a, 28b are separated and joined at intervals by bracing pieces constituted by metal plates 29 welded to the webs of the sections 28a, 28b. Such an embodiment has the advantage of great simplicity of construction and provides a very satisfactory thermal break between walls, over the entire length of the stiffener 27.
