Abstract

The element (1) moulded from synthetic material has a thin wall (2) whose outer face has an attractive appearance which imitates traditional coverings (slates, tiles, etc.). Two consecutive ends of the element comprise profiles intended for assembly which form depressions with a U-shaped cross-section (12 and 15), which are open on the side of the outer face (3) and arranged in order to be communicating. The front and rear ends of the element have a tongue (16) which engages in a groove (17) on mounting. The groove (17) opens out into the transverse depression (12) with a U-shaped cross-section on the arm (10) of the U placed on the inner side of the element. This type of element is particularly advantageous for constructing building roofs. <IMAGE>

Description

La présente invention concerne un élément préfabriqué pour la construction de panneaux de recouvrement, du type comportant : une paroi sensiblement plane dont une face destinée à être située à l'extérieur présente un relief esthétique, imitant éventuellement l'aspect des revêtements traditionnels, et l'autre face, interne, comprend des nervures de raidissage, sensiblement parallèles et orientées longitudinalement selon la ligne de plus grande pente de l'élément, seules en appui sur la structure porteuse et délimitant des espaces libres entre la paroi et la structure porteuse sur la dimension longitudinale du panneau constitué par l'assemblage d'éléments ; des moyens d'assemblage de l'élément à d'autres éléments identiques disposés côte à côte, composés pour l'essentiel d'emboîtement de profils d'extrémités complémentaires solidaires ou rapportés ; des moyens de fixation de l'élément à une structure porteuse par l'intermédiaire des nervures de la face interne.The present invention relates to a prefabricated element for the construction of covering panels, of the type comprising: a substantially planar wall, one face of which intended to be situated outside presents an aesthetic relief, possibly imitating the appearance of traditional coverings, and the other side, internal, comprises stiffening ribs, substantially parallel and oriented longitudinally along the line of greatest slope of the element, alone bearing on the support structure and delimiting free spaces between the wall and the support structure on the longitudinal dimension of the panel formed by the assembly of elements; means for assembling the element to other identical elements arranged side by side, essentially composed of interlocking complementary end profiles joined or attached; means for fixing the element to a support structure by means of the ribs on the internal face.

L'invention vise à exploiter au mieux les avantages que peut offrir une telle conception lors de son utilisation, ces avantages étant notamment :

  • - une circulation d'air ascendante en sous-toiture évitant les phénomènes de condensation et augmentant le confort thermique du volume habitable concerné ;
  • - des liaisons et fixations des éléments permettant divers degrés de liberté pour absorber les dilatations ;
  • - un système de liaison entre les éléments, qui permet le drainage des eaux longitudinalement et transversalement;
  • - un espacement des points d'appui sur la structure porteuse, choisi indépendamment de celui des reliefs imités de la face externe de l'élément.
The invention aims to make the best use of the advantages that such a design can offer during its use, these advantages being in particular:
  • - an ascending air circulation under the roof avoiding the phenomena of condensation and increasing the thermal comfort of the living space concerned;
  • - connections and fixings of the elements allowing various degrees of freedom to absorb expansions;
  • - a connection system between the elements, which allows water drainage longitudinally and transversely;
  • - a spacing of the support points on the supporting structure, chosen independently of that of the reliefs imitated from the external face of the element.

Selon la présente invention, on cherche en particulier à éviter encore mieux toute formation d'humidité sous la face interne de la paroi constituée d'éléments, ce qui est obtenu non seulement en permettant la libre circulation de l'air ascendant, mais en assurant en plus un drainage des eaux de ruissellement à la périphérie de l'élément. A cet effet, l'élément de l'invention se caractérise en ce que les extrémités de l'élément, prises opposées deux à deux, présentent des profils complémentaires, transversaux et parallèles aux nervures, destinés à s'emboîter l'un dans l'autre pour assurer l'assemblage à d'autres éléments adjacents, deux desdits profils d'extrémités, placés consécutivement sur le pourtour--de l'élément, étant constitués dans la paroi de l'élément par une dépression à section en U, ouverte du côté de la face externe et agencés pour que la dépression en U de l'un communique avec la dépression en U de l'autre à leur jonction, à l'angle notamment supérieur d'un élément en situation.According to the present invention, it is sought in particular to avoid even better any formation of moisture under the internal face of the wall made up of elements, which is obtained not only by allowing the free circulation of ascending air, but by in addition a drainage of runoff water at the periphery of the element. To this end, the element of the invention is characterized in that the ends of the element, taken opposite two by two, have complementary profiles, transverse and parallel to the ribs, intended to fit one into the 'other to ensure assembly with other adjacent elements, two of said end profiles, placed consecutively on the periphery - of the element, being formed in the wall of the element by a depression with a U-section, open on the side of the external face and arranged so that the U-shaped depression of one communicates with the U-shaped depression of the other at their junction, at the notably upper angle of an element in situation.

C'est ainsi que les eaux de ruissellement qui arrivent à s'infiltrer entre les assemblages par emboîtement des éléments, sont récupérées transversalement puis collectées longitudinalement jusqu'au bas du panneau grâce aux dépressions à section en U communicantes. Lorsque le ruissellement cesse, une circulation d'air-remplace l'eau-et participe à l'assèchement par la face interne des boues humides pouvant se former avec les poussières de l'atmosphère aux joints des éléments.This is how the runoff which arrives to infiltrate between the assemblies by interlocking of the elements, is recovered transversely and then collected longitudinally to the bottom of the panel thanks to the depressions with communicating U section. When runoff ceases, air circulation replaces water and participates in the drying by the internal face of wet sludge which can form with atmospheric dust at the joints of the elements.

De plus, l'étanchéité de l'assemblage transversal est augmentée en complétant l'emboîtement par un engagement dans le plan et l'épaisseur de la paroi de l'élément, ce qui procure l'avantage supplémentaire de rendre indissociables les éléments, particulièrement en présence de vent. Cet assemblage, par engagement latéral, est disposé de manière à s'effectuer dans le conduit en U de drainage transversal de manière à assurer dans tous les cas une reprise de l'eau qui pourrait franchir le joint d'assemblage.In addition, the tightness of the transverse assembly is increased by completing the fitting by engagement in the plane and the thickness of the wall of the element, which provides the additional advantage of making the elements inseparable, particularly in the presence of wind. This assembly, by lateral engagement, is arranged so as to be carried out in the U-shaped transverse drainage conduit so as to ensure in all cases a recovery of water which could pass through the assembly joint.

A cet effet, l'élément comporte des moyens d'assemblage de deux éléments côte à côte par les extrémités transversales aux nervures, réalisés par l'emboîtement de profils complémentaires, notamment d'arêtes se logeant dans une dépression à section en U, et complétés par l'engagement, dans la direction sensiblement du plan de l'élément, d'une languette dans une rainure qui débouche dans la dépression transversale à section en U et sur la branche du U placée du côté intérieur de l'élément.To this end, the element comprises means for assembling two elements side by side by the ends transverse to the ribs, produced by the interlocking of complementary profiles, in particular of edges accommodating in a depression in U-shaped section, and supplemented by the engagement, in the direction substantially of the plane of the element, of a tongue in a groove which opens into the transverse depression of U-section and on the branch of the U placed on the inner side of the element.

Par ailleurs, l'existence des nervures a permis la création, pour l'élément de l'invention, d'un système simple de fixation à la structure porteuse. On prévoit avantageusement, dans l'épaisseur de la nervure, des pièces de fixation susceptibles de coopérer, pour immobiliser l'élément, avec des pièces solidaires de la structure porteuse.Furthermore, the existence of the ribs has enabled the creation, for the element of the invention, of a simple system of attachment to the support structure. Advantageously, there are provided, in the thickness of the rib, fastening parts capable of cooperating, to immobilize the element, with parts integral with the support structure.

Selon une forme de réalisation préférée, mais non limitative, des écrous métalliques sont inclus dans l'âme des nervures. On solidarise alors l'élément à la structure porteuse à l'aide de tiges filetées vissées dans les écrous du côté de la face interne. Ce type de fixation permet un espacement des points d'appui sur la structure porteuse, choisie indépendamment du pas des dessins en relief retenus pour l'esthétique de la face externe de l'élément. Dans ce but, deux nervures au moins de l'élément présentent localement, incluse dans l'âme de la nervure et débouchant sur son arête, une pièce de fixation, notamment un écrou, qui s'engage sur une autre pièce de fixation, notamment une tige filetée, solidaire de la structure porteuse pour immobiliser l'élément en position.According to a preferred, but not limiting, embodiment, metal nuts are included in the core of the ribs. The element is then secured to the supporting structure using threaded rods screwed into the nuts on the side of the internal face. This type of attachment allows spacing of the support points on the supporting structure, chosen independently of the pitch of the relief drawings retained for the aesthetics of the external face of the element. For this purpose, at least two ribs of the element have locally, included in the core of the rib and opening on its edge, a fixing part, in particular a nut, which engages on another fixing part, in particular a threaded rod, integral with the support structure to immobilize the element in position.

Selon une variante préférée, la retenue de l'élément peut être obtenue en le bridant, par un bord latéral, contre la structure porteuse à l'aide d'une patte de ferrure solidaire de ladite structure. Ce bridage par simple appui procure les degrés de liberté de l'élément, nécessaires pour absorber les dilatations. On disposera avantageusement ce bridage sur un profilé complémentaire transversal qui sera réalisé de manière à intégrer, puis masquer complètement, la ferrure derrière les surfaces externes des éléments assemblés.According to a preferred variant, the retention of the element can be obtained by clamping it, by a lateral edge, against the supporting structure using a fitting lug secured to said structure. This clamping by simple support provides the degrees of freedom of the element, necessary to absorb the expansions. This clamping will advantageously be arranged on a complementary transverse profile which will be produced so as to integrate, then completely mask, the fitting behind the external surfaces of the assembled elements.

A cet effet, l'élément comporte des profilés complémentaires d'assemblage transversal qui permettent l'immobilisation de l'élément par bridage contre la structure porteuse de la branche extérieure du U de la dépression transversale, à l'aide de la patte libre d'une équerre solidaire de la structure porteuse. On convient que l'élément préfabriqué, objet de l'invention, est conçu, sans que cela soit limitatif, pour réaliser des panneaux de toiture de maison. En raison du système de fixation, les deux éléments qui se trouvent au faîte du toit laissent entre eux un espace. Il convient donc de combler et d'étancher cet espace et à cet effet la pièce de faîtage est constituée par une cornière coiffant les extrémités supérieures des panneaux de toiture et comportant, sur la face interne de chacune de ses ailes, un profilé destiné à immobiliser le faîtage en position en s'engageant dans un profilé complémentaire rendu solidaire de chacun des bords libres des panneaux.To this end, the element has complementary transverse assembly profiles which allow the element to be immobilized by clamping against the supporting structure of the outer branch of the U of the transverse depression, using the free tab d '' a bracket attached to the supporting structure. It is agreed that the prefabricated element, object of the invention, is designed, without this being limiting, for producing house roof panels. Due to the fixing system, the two elements at the roof ridge leave a space between them. It is therefore necessary to fill and seal this space and for this purpose the ridge piece is constituted by an angle iron covering the upper ends of the roofing panels and comprising, on the internal face of each of its wings, a profile intended to immobilize the ridge in position by engaging in a complementary profile made integral with each of the free edges of the panels.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description, ci-après donnée à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels :

  • La figure 1 est une vue en perspective avec coupe partielle d'un panneau de revêtement selon l'invention ;
  • la figure 2 est une vue latérale de deux éléments assemblés ;
  • la figure 3 est une vue d'extrémité montrant l'assemblage de deux panneaux consécutifs ;
  • la figure 4 est une vue en perspective montrant le bridage d'un élément sur la structure porteuse ; et
  • la figure 5 représente schématiquement un élément de faîtage selon l'invention..
Other characteristics and advantages of the invention will appear during the description, given below by way of nonlimiting example with reference to the appended drawings in which:
  • Figure 1 is a perspective view with partial section of a covering panel according to the invention;
  • Figure 2 is a side view of two assembled elements;
  • Figure 3 is an end view showing the assembly of two consecutive panels;
  • Figure 4 is a perspective view showing the clamping of an element on the support structure; and
  • FIG. 5 schematically represents a ridge element according to the invention.

Dans l'exemple représenté et décrit ci-après, on conviendra, sans que cela soit limitatif, que l'élément préfabriqué objet de l'invention est conçu pour réaliser des panneaux de toiture de maison.In the example shown and described below, it will be understood, without this being limiting, that the prefabricated element that is the subject of the invention is designed to produce house roof panels.

A cet égard, on indiquera dès à présent que lorsqu'on regarde la figure 1, l'arête faîtière du toit se trouve vers le haut et la base du toit vers le bas de la figure.In this regard, it will be indicated now that when we look at Figure 1, the ridge edge of the roof is up and the base of the roof down in the figure.

Dans l'exemple représenté, l'élément préfabriqué a été désigné de façon générale en 1 et il présente une forme carrée ou sensiblement rectangulaire. L'élément moulé en une seule pièce en un matériau synthétique, armé ou non, comporte une paroi 2 mince, d'une épaisseur de quelques millimètres, dont la face externe 3 destinée à être visible de l'extérieur présente un aspect esthétique particulier, imitant dans l'exemple représenté une succession d'ardoises se chevauchant, le repère 5 désignant des épaulements figurant les bords visibles des ardoises. De plus, des rainures 4 alternées sont pratiquées dans la face externe 3, dans le sens de la pente du toit, pour compléter l'imitation.In the example shown, the prefabricated element has been generally designated at 1 and it has a square or substantially rectangular shape. The element molded in one piece from a synthetic material, reinforced or not, has a thin wall 2, a thickness of a few millimeters, whose external face 3 intended to be visible from the outside has a particular aesthetic appearance, imitating in the example shown a succession of overlapping slates, the reference 5 designating shoulders representing the visible edges of the slates. In addition, alternating grooves 4 are made in the external face 3, in the direction of the roof slope, to complete the imitation.

A partir de la face interne 6 de la paroi 2, une série de nervures parallèles 7 s'étendent dans le sens de la pente du toit. Les nervures 9a et 9c forment les bords latéraux opposés de l'élément, alors que les nervures 7 désignent les nervures intermédiaires. Avantageusement, ces nervures sont formées au droit des rainures 4, de telle sorte que l'affaiblissement local dû à ces rainures soit compensé largement par la surépaisseur des nervures 7.From the internal face 6 of the wall 2, a series of parallel ribs 7 extend in the direction of the slope of the roof. The ribs 9a and 9c form the opposite lateral edges of the element, while the ribs 7 designate the intermediate ribs. Advantageously, these ribs are formed in line with the grooves 4, so that the local weakening due to these grooves is largely compensated for by the extra thickness of the ribs 7.

A l'extrémité haute de l'élément 1, destiné à être montée vers le faite du toit, on a prévu un profilé constitué par une dépression 12 en forme de U ouvert vers l'extérieur. Cette dépression 12 présente deux cloisons 10 et 11 sensiblement perpendiculaires à la paroi 2. Une rainure 17, sensiblement parallèle à la paroi 2, débouche dans la cloison 10 de la dépression 12. Cette rainure 17 est destinée à recevoir la languette 16 du profilé complémentaire de l'autre extrémité transversale. La dépression 12 communique avec la dépression 15 du profilé latéral de l'élément. La communication est établie par le passage 21.At the upper end of the element 1, intended to be mounted towards the roof, there is provided a profile constituted by a depression 12 in the shape of a U open towards the outside. This depression 12 has two partitions 10 and 11 substantially perpendicular to the wall 2. A groove 17, substantially parallel to the wall 2, opens into the partition 10 of the depression 12. This groove 17 is intended to receive the tongue 16 of the complementary profile from the other transverse end. The depression 12 communicates with the depression 15 of the lateral profile of the element. Communication is established by passage 21.

Les eaux drainées dans la dépression 12 sont collectées dans la dépression 15, après franchissement de l'ouverture 21, pour être évacuées à la base du panneau de toiture.The water drained into the depression 12 is collected in the depression 15, after crossing the opening 21, to be discharged at the base of the roofing panel.

A l'extrémité basse de l'élément 1, on a prévu un profilé constitué par une cloison 8 sensiblement perpendiculaire à la paroi 2 et une languette 16 sensiblement parallèle à la surface de l'élément. Cette cloison 8 est destinée à s'emboîter contre la cloison 10 complémentaire, tandis que la languette 16 s'engage dans la rainure 17 d'une extrémité transversale d'un autre élément.At the lower end of the element 1, a profile is provided consisting of a partition 8 substantially perpendicular to the wall 2 and a tongue 16 substantially parallel to the surface of the element. This partition 8 is intended to fit against the complementary partition 10, while the tongue 16 engages in the groove 17 of a transverse end of another element.

Comme on le voit particulièrement aux figures 1 et 2, les éléments une fois mis en place se complètent parfaitement et la dépression 12 de drainage est masquée par la paroi 2. L'autre cloison 11 de la dépression 12 s'encastre dans une échancrure 23 des nervures 7, plus particulièrement dans la découpe 22. Dans une autre forme de réalisation, la cloison 11 pourrait s'emboîter sur une cloison complémentaire, en sous-face de l'élément, reliant les extrémités basses des nervures.As seen particularly in Figures 1 and 2, the elements once in place complement each other perfectly and the drainage depression 12 is masked by the wall 2. The other partition 11 of the depression 12 is embedded in a notch 23 ribs 7, more particularly in the cutout 22. In another embodiment, the partition 11 could fit onto a complementary partition, on the underside of the element, connecting the lower ends of the ribs.

L'assemblage des éléments dans le sens longitudinal du toit est représenté à la figure 3. On voit que celui-ci est réalisé par l'emboîtement de deux nervures d'extrémité latérales 9a et 9b formant les branches d'un U par-dessus les cloisons 13 et 14 de la dépression 15. Les nervures particulières 9a et 9b, ainsi que les cloisons 13 et 14, sont toutes sensiblement perpendiculaires à la paroi 2. Après emboîtement de deux éléments côte à côte, la dépression 15 est parfaitement masquée par la paroi 2. Afin de bien positionner un élément par rapport à l'autre, des excroissances de matière 18, placées entre la nervure 9c et la cloison 13 à intervalles réguliers, s'engagent dans les échancrures 19 pratiquées sur la nervure 9a, dans une forme de découpe complémentaire des excroissances. On décrira maintenant la manière dont les éléments sont fixés à la structure porteuse L. Cette fixation est représentée sur la figure 4 où un élément 1 est bridé contre un linteau L de la structure porteuse par la ferrure en forme d'équerre 24 solidaire du linteau par la fixation 25.The assembly of the elements in the longitudinal direction of the roof is shown in Figure 3. It can be seen that this is achieved by the interlocking of two lateral end ribs 9a and 9b forming the branches of a U over the partitions 13 and 14 of the depression 15. The particular ribs 9a and 9b, as well as the partitions 13 and 14, are all substantially perpendicular to the wall 2. After fitting two elements side by side , the depression 15 is perfectly masked by the wall 2. In order to properly position one element relative to the other, protuberances of material 18, placed between the rib 9c and the partition 13 at regular intervals, engage in the notches 19 made on the rib 9a, in a form of cutting complementary to the growths. We will now describe the way in which the elements are fixed to the supporting structure L. This fixing is represented in FIG. 4 where an element 1 is clamped against a lintel L of the supporting structure by the bracket-shaped fitting 24 secured to the lintel by fixing 25.

La patte de l'équerre 24 maintient l'élément 1 contre le linteau en s'appuyant sur la cloison 11 du profilé d'extrémité. On voit que l'épaisseur de cette patte et la hauteur de la cloison 11 doivent être telles que leur superposition, lors du bridage, permet l'engagement de l'élément adjacent dans la rainure 17 et son emboîtement sur la cloison 11. Cette fixation devient invisible après l'assemblage des éléments formant le panneau de toiture. Elle permet de légers déplacements, parallèlement ou transversalement aux nervures. La présence des nervures 7 sous la dépression 12 en forme de U assure la continuité des espaces libres longitudinaux et la libre circulation de l'air ascendant sous la paroi de l'élément.The bracket tab 24 holds the element 1 against the lintel by pressing on the partition 11 of the end profile. It can be seen that the thickness of this tab and the height of the partition 11 must be such that their superimposition, during clamping, allows the adjacent element to be engaged in the groove 17 and its fitting onto the partition 11. This fixing becomes invisible after the assembly of the elements forming the roofing panel. It allows slight displacements, parallel or transverse to the ribs. The presence of the ribs 7 under the U-shaped depression 12 ensures the continuity of the longitudinal free spaces and the free circulation of the ascending air under the wall of the element.

Si la structure porteuse se présente sous la forme d'une surface plane continue, on modifie légèrement l'équerre 24 tout en conservant la méthode de fixation. La nouvelle ferrure a alors la forme d'une double équerre en S dont une patte bride la cloison 11 comme précédemment et l'autre, sensiblement parallèle à la première, prend appui et se fixe sur la structure plane.If the supporting structure is in the form of a continuous flat surface, the bracket 24 is slightly modified while retaining the method of attachment. The new fitting then has the form of a double S-bracket, one leg of which flanges the partition 11 as before and the other, substantially parallel to the first, is supported and fixed on the flat structure.

Les deux éléments standard 1 de l'invention qui se trouvent au faîte du toit laissent entre eux un espace. On prévoit donc un élément faitier qui pourra être constitué, comme représenté à la figure 5, par une cornière 26 qui vient coiffer les deux éléments terminaux. Pour fixer la cornière 26, on utilise une pièce de fixation intermédiaire 28 qui se présente sous la forme d'un profilé. La rainure 29 de cette pièce de fixation s'emboîte sur la paroi 2 de l'élément. La pièce de fixation est rendue solidaire de l'élément par la pose d'un rivet 31 reliant la paroi 2 à la pièce 28.The two standard elements 1 of the invention which are at the roof ridge leave a space between them. There is therefore provided a ridge element which may be constituted, as shown in Figure 5, by an angle 26 which covers the two end elements. To fix the angle 26, an intermediate fixing piece 28 is used which is in the form of a profile. The groove 29 of this fixing piece fits on the wall 2 of the element. The fixing part is made integral with the element by the installation of a rivet 31 connecting the wall 2 to the part 28.

Un profilé 30, solidaire de la pièce de fixation 28 par un bord, ménage sur la surface de la pièce une rainure profonde. On équipe les deux éléments terminaux de la toiture de cette pièce de fixation 28. On introduit alors les deux languettes 27 que comporte la surface interne des ailes de la cornière 26 dans les rainures aménagées sur les pièces de fixation 28. On solidarise ainsi l'élément faîtier à la couverture de la toiture. On remarquera que la fixation de la cornière 26 sur le faîtage pourra se faire par simple coulissement selon la direction de l'arête terminale du toit.A profile 30, integral with the fixing piece 28 by an edge, provides a deep groove on the surface of the piece. We equip the two end elements of the roof of this fastener 28. We then introduce the two tabs 27 that comprise the inner surface of the wings of the angle iron 26 in the grooves provided on the fasteners 28. This secures the roof element on the roof cover. Note that the fixing of the angle 26 on the ridge can be done by simple sliding in the direction of the end edge of the roof.

Au niveau de la faîtière 26, la ventilation est assurée par échappement latéral de l'air aux extrémités du toit, ce qui permet de supprimer ainsi les systèmes d'aération de tous genres.At the ridge 26, ventilation is ensured by lateral exhaust of the air at the ends of the roof, which thus eliminates ventilation systems of all kinds.
