Abstract

The covering consists of a corrugated supporting panel (3) with ribs (6), an insulating layer (9) and a waterproof covering material. The insulating layer is connected to the supporting panel by fixings (13). The fixings are joined to insert strips (14) adapted to the shape and dimensions of the ribs (6) and joined to them by fixings (18). Alternatively, the insert strips can be of different shapes, either with lengthwise folds or tongues to attach them to the ribs. They can have up-turned lower edges to join them to the fixings between the supporting panel and roof girders (2) below them.

Description

La présente invention est relative à une couverture étanche pour toiture comprenant un élément de support, généralement une tôle profilée, un matelas isolant et au moins un revêtement d'étanchéité, l'ensemble étant fixé à des éléments de structure de la toiture, tels que des pannes.The present invention relates to a waterproof roof covering comprising a support element, generally a profiled sheet, an insulating mat and at least one waterproof covering, the whole being fixed to structural elements of the roof, such as breakdowns.

Pour résister aux efforts en compression ou en arrachement notamment en cas de violentes tempêtes, il est d'usage de fixer mécaniquement au moins le matelas isolant à la tôle profilée. Cette fixation mécanique à l'aide de vis par exemple traverse la tôle profilée et est visible en sous-face de la couverture, ce qui n'est pas satisfaisant.To resist compressive or tearing forces, particularly in the event of severe storms, it is customary to mechanically fix at least the insulating mat to the profiled sheet. This mechanical fixing using screws for example passes through the profiled sheet and is visible on the underside of the cover, which is not satisfactory.

Pour rendre ces fixations non invisible, on a déjà proposé par exemple dans la publication de brevet EP 0 553 012 d'utiliser, en tant qu'élément de support, des tôles contiguës comportant des bords se superposant mutuellement de l'une à l'autre dans une zone de recouvrement marginale formant un logement fermé dans lequel s'étend l'extrémité des moyens de fixation.To make these fasteners non-invisible, it has already been proposed for example in patent publication EP 0 553 012 to use, as a support element, contiguous sheets having edges overlapping each other from one to the another in a marginal overlap zone forming a closed housing in which extends the end of the fixing means.

Cette solution nécessite néanmoins l'utilisation de tôles profilées spécifiques.This solution nevertheless requires the use of specific profiled sheets.

L'invention propose une couverture étanche pour toiture utilisant des éléments de supports profilés standard comportant des nervures sur lesquels sont fixés mécaniquement au moins un matelas d'isolation, les fixations s'effectuant sur un profil rapporté sur au moins une des nervures et de dimensions et forme adaptées aux dimensions et forme de la nervure et formant avec elles un espace destiné notamment à rendre non visibles en sous-toiture les moyens mécaniques de fixation, le profil rapporté étant lui-même fixé sur les éléments de support profilés.The invention provides a waterproof roof covering using standard profiled support elements comprising ribs on which at least one insulation mat is mechanically fixed, the fastenings being carried out on a profile attached to at least one of the ribs and of dimensions and shape adapted to the dimensions and shape of the rib and forming with them a space intended in particular to make the mechanical fixing means not visible under the roof, the added profile itself being fixed on the profiled support elements.

Le profil rapporté utilisé selon l'invention présente une structure adaptée à la structure de la nervure et, de préférence, une structure permettant un montage par emboîtement au moins partiel dans la nervure du support profilé, la face sur laquelle s'effectue la fixation étant disposée en position rapportée à un niveau sensiblement égal au niveau supérieur des nervures. Le profil rapporté présente le cas échéant une élasticité permettant notamment un emboitement au moins partiel.The attached profile used according to the invention has a structure adapted to the structure of the rib and, preferably, a structure allowing mounting by at least partial interlocking in the rib of the profiled support, the face on which the fixing takes place. disposed in the attached position at a level substantially equal to the upper level of the ribs. The added profile has, where appropriate, an elasticity allowing in particular an interlocking that is at least partial.

Selon une première forme de réalisation de l'invention, le profil rapporté est un profil sensiblement plan prenant appui sur des parties des bords supérieures de la nervure. Afin d'augmenter sa rigidité, ce profil peut présenter une ou plusieurs nervures longitudinales, c'est-à-dire parallèles à la nervure du support profilé. Ce profil plan peut aussi présenter une structure facilitant son centrage et sa mise en place dans la nervure du support profilé. On peut ainsi prévoir des crevés rabattus sur les flancs de la nervure ou encore au moins un pliage pouvant épouser ce flanc de la nervure. Le profil rapporté peut être fixé sur les bords de la nervure du support profilé par des vis de petites dimensions quasi invisibles.According to a first embodiment of the invention, the added profile is a substantially planar profile bearing on parts of the upper edges of the rib. In order to increase its rigidity, this profile may have one or more longitudinal ribs, that is to say parallel to the rib of the profiled support. This planar profile can also have a structure facilitating its centering and its positioning in the rib of the profiled support. It is thus possible to provide punctures folded over the sides of the rib or at least one folding which can match this side of the rib. The attached profile can be fixed to the edges of the rib of the profiled support by screws of small dimensions which are almost invisible.

Selon une autre forme de réalisation de l'invention, le profil rapporté présente une structure permettant un emboîtement total ou quasi total dans une nervure de l'élément de support en formant un espace fermé. Le profil rapporté peut alors présenter la forme d'un U inversé, les deux ailes du U, avantageusement en tôle mince, venant le cas échéant s'appuyer sur les flancs inclinés de la nervure en s'adaptant grâce à l'élasticité des ailes à cette inclinaison des flancs de la nervure. Le système de fixation du profil rapporté sur l'élément support peut alors utiliser le même système de fixation que l'élément support dans la structure de la toiture.According to another embodiment of the invention, the added profile has a structure allowing a total or almost total fitting in a rib of the support element by forming a closed space. The added profile can then have the shape of an inverted U, the two wings of the U, advantageously made of thin sheet metal, coming if necessary to bear on the inclined sides of the rib, adapting by virtue of the elasticity of the wings. at this inclination of the sides of the rib. The profile fixing system attached to the support element can then use the same fixing system as the support element in the structure of the roof.

Selon une autre forme de réalisation de l'invention, le profil rapporté peut être formé de deux élément s'assemblant pour former un espace fermé dans une nervure de l'élément de support.According to another embodiment of the invention, the added profile can be formed of two elements joining together to form a closed space in a rib of the support element.

Sur la figure 1, la couverture étanche 1 selon l'invention est une couverture pour toiture d'un local, reposant sur des pannes 2. La couverture 1 comprend un élément de support 3 formé de tôles profilées 4 contiguës qui peuvent présenter des petites nervures longitudinales 5 en vue d'améliorer leur rigidité.In FIG. 1 , the waterproof cover 1 according to the invention is a cover for the roof of a room, based on purlins 2. The cover 1 comprises a support element 3 formed from contiguous profiled sheets 4 which may have small ribs longitudinal 5 to improve their rigidity.

L'élément de support 3 présente des nervures 6 dont la base 7 est en appui et fixée par des moyens mécaniques 8 sur les pannes 2. Sur l'élément de support 3 sont disposés des panneaux 9 isolants thermiques et/ou acoustiques notamment en laine minérale.The support element 3 has ribs 6 whose base 7 is supported and fixed by mechanical means 8 on the purlins 2. On the support element 3 are arranged panels 9 thermal and / or acoustic insulation, in particular wool mineral.

Le panneau isolant 9 peut avantageusement comporter un revêtement de liaison 10 notamment à base d'un matériau bitumineux. Sur ce panneau 9 est enfin disposée et liée au moins une couche 11 d'un revêtement étanche qui peut également être à base d'un matériau bitumineux.The insulating panel 9 can advantageously include a bonding coating 10 in particular based on a bituminous material. On this panel 9 is finally arranged and bonded at least one layer 11 of a waterproof coating which can also be based on a bituminous material.

Les panneaux isolants sont fixés mécaniquement par exemple à l'aide de plaquettes 12 et de vis 13 ou de goujons dans des profils rapportés 14 en tôle par exemple, qui recouvrent au moins une des nervures 6 de l'élément support. Les nervures 6 recouvertes par les profils rapportés sont espacées régulièrement. Généralement, au moins une nervure 6 est recouverte par un profil rapporté pour chaque tôle profilée.The insulating panels are mechanically fixed, for example using plates 12 and screws 13 or studs in added profiles 14 made of sheet metal, for example, which cover at least one of the ribs 6 of the support element. The ribs 6 covered by the added profiles are regularly spaced. Generally, at least one rib 6 is covered by an attached profile for each profiled sheet.

Sur la figure 2, le profil rapporté 14 en tôle de 1 mm d'épaisseur par exemple prend appui sur les bords supérieurs 15 de la nervure et présente avantageusement deux plis longitudinaux 16 qui facilitent un bon centrage du profil rapporté sur la nervure. Le profil rapporté 14 peut aussi présenter un pli central 17 améliorant la rigidité du profil. Le profil rapporté 14 peut être fixé à l'élément de support 3 par des vis 18 de petites dimensions quasi invisibles en sous-toiture. Comme représenté sur la figure, le panneau isolant 9 est fixé sur le profil rapporté à l'aide de plaquettes 12 et de vis 13 qui traversent ce profil. L'extrémité des vis est alors située dans l'espace fermé 19 créé par l'association du profil et de la nervure, et est non visible en sous-toiture. Le nombre de plaquettes 12 et de vis 13 peut varier d'une couverture à l'autre selon notamment le type de panneau utilisé, la situation géographique de la couverture, etc... On comprend que les vis de fixation des panneaux seront disposés selon des lignes qui correspondent à la disposition des profils rapportés.In FIG. 2 , the attached profile 14 made of sheet metal 1 mm thick for example bears on the upper edges 15 of the rib and advantageously has two longitudinal folds 16 which facilitate good centering of the profile added on the rib. The added profile 14 may also have a central fold 17 improving the rigidity of the profile. The added profile 14 can be fixed to the support element 3 by screws 18 of small dimensions which are almost invisible under the roof. As shown in the figure, the insulating panel 9 is fixed to the added profile using plates 12 and screws 13 which pass through this profile. The end of the screws is then located in the closed space 19 created by the association of the profile and the rib, and is not visible under the roof. The number of plates 12 and screws 13 may vary from one cover to another depending in particular on the type of panel used, the geographic location of the cover, etc. It is understood that the screws for fixing the panels will be arranged according to lines that correspond to the arrangement of the profiles reported.

Sur la figure 3 on a représenté une variante d'un profil rapporté 20 selon l'invention. Dans cette variante, le profil rapporté 20 est entièrement emboîté dans une nervure 6 de l'élément support 3. Le profil 20 présente une forme sensiblement trapézoïdale 21, la grande base 22 servant à la fixation notamment par des plaquettes 12 et des vis 13 des panneaux isolants 9. La fixation du profil rapporté 20 sur l'élément support 3 peut être réalisée par les mêmes moyens que ceux utilisés pour la fixation de l'élément support sur la panne. Il s'agit par exemple de vis 8 qui ici sont munies d'entretoises 23 et rondelles 24 formant un logement 26 et permettant un montage par « clipsage » c'est-à-dire par pincement et/ou emprisonnement des deux ailes recourbées 25 formant la petite base du trapèze. Les deux côtés 27 du trapèze sont sensiblement parallèles et le cas échéant au contact des flancs 28 de la nervure. La mise en place du profil rapporté est facilité par une élasticité des côtés et des ailes de celui-ci qui peuvent s'engager sous la rondelle 24 lors de la mise en place du profil par simple poussée de haut en bas. FIG. 3 shows a variant of an attached profile 20 according to the invention. In this variant, the added profile 20 is fully fitted into a rib 6 of the support element 3. The profile 20 has a substantially trapezoidal shape 21, the large base 22 serving for fixing in particular by plates 12 and screws 13 of the insulating panels 9. The attachment of the added profile 20 to the support element 3 can be carried out by the same means as those used for the attachment of the support element to the purlin. These are for example screws 8 which here are provided with spacers 23 and washers 24 forming a housing 26 and allowing mounting by “clipping”, that is to say by pinching and / or imprisonment of the two curved wings 25 forming the small base of the trapezoid. The two sides 27 of the trapezium are substantially parallel and, where appropriate, in contact with the sides 28 of the rib. The establishment of the added profile is facilitated by an elasticity of the sides and of the wings thereof which can engage under the washer 24 during the establishment of the profile by simple push from top to bottom.

Sur la figure 4 est représentée une troisième variante d'un profil rapporté utilisé conformément à l'invention. Dans cette variante, le profil 29 est formé de deux pièces 30, 31 pouvant se monter l'une sur l'autre par pincement et formant ensemble une forme à section trapézoïdale. Une pièce de base 30 est fixée sur l'élément de support 3 à l'aide des moyens 8 utilisés pour la fixation de l'élément de support 3 sur la panne 2. Cette pièce de base 30 présente la forme d'un U dont la base des branches est inclinée pour épouser la pente des flancs 28 de la nervure 6. L'extrémité supérieure 32 du U est recourbée vers l'extérieur de manière à fixer la pièce de dessus 31 qui à cette fin présente également des extrémités 33 de bras recourbés. FIG. 4 shows a third variant of an attached profile used in accordance with the invention. In this variant, the profile 29 is formed of two parts 30, 31 which can be mounted one on the other by pinching and together forming a shape with a trapezoidal section. A base part 30 is fixed to the support element 3 using the means 8 used for fixing the support element 3 to the purlin 2. This base part 30 has the shape of a U whose base of the branches is inclined to follow the slope of the sides 28 of the rib 6. The upper end 32 of the U is bent outward so as to fix the top piece 31 which to this end also has ends 33 of curved arms.

Le panneau isolant est fixé par l'intermédiaire de plaquettes 12 et de vis 13 sur la base supérieure 34 de la pièce de dessus 31.The insulating panel is fixed by means of plates 12 and screws 13 to the upper base 34 of the top piece 31.

Les extrémités 35 des vis de fixation sont disposées dans l'espace fermé 19 constitué ici par le profil rapporté.The ends 35 of the fixing screws are arranged in the closed space 19 formed here by the attached profile.

Sur la figure 5 est représentée une quatrième variante d'un profil rapporté selon l'invention. Dans cette variante, le profil rapporté 36 est entièrement emboîté dans une nervure 6 de l'élément support. Le profil 36 présente une forme sensiblement trapézoïdale 37, la petite base formée de deux ailes 38 reposant sur l'élément support 3, la grande base 39 est fixée à l'élément de support 3 par les mêmes vis qui assurent la fixation de cet élément à la panne 2. Le panneau isolant est fixé sur le profil rapporté 36 par des plaquettes 12 et des vis 13 dont les extrémités débouchent dans l'espace intérieur 19 et sont donc non visibles en sous- toiture. FIG. 5 shows a fourth variant of an attached profile according to the invention. In this variant, the added profile 36 is fully fitted into a rib 6 of the support element. The profile 36 has a substantially trapezoidal shape 37, the small base formed by two wings 38 resting on the support element 3, the large base 39 is fixed to the support element 3 by the same screws which fix the element on failure 2. The insulating panel is fixed to the added profile 36 by plates 12 and screws 13, the ends of which open into the interior space 19 and are therefore not visible under the roof.

Sur la figure 6, est représentée une autre variante d'un profil rapporté 40 selon l'invention qui en combinaison avec une nervure 6 forme un espace 19 destiné à rendre non visibles, en sous face de la couverture, les extrémités des vis de fixation 13 des panneaux isolants (non représentés). Le profil rapporté 40 sensiblement plat, présente des crevés 41 disposés selon deux lignes longitudinales, parallèles aux bords supérieurs de la nervure, séparées de la distance correspondant à l'ouverture supérieure de ladite nervure, de manière à permettre d'une part un centrage du profil rapporté sur ladite nervure et d'autre part sa fixation par vis 42, les parties rabattues ou languettes 43 des crevés venant s'appuyer sur les extrémités supérieures 44 des flans inclinés 28 de la nervure.In FIG. 6, another variant of an attached profile 40 according to the invention is shown, which in combination with a rib 6 forms a space 19 intended to make the ends of the fixing screws not visible, on the underside of the cover. 13 insulating panels (not shown). The substantially flat attached profile 40 has punctures 41 arranged in two longitudinal lines, parallel to the upper edges of the rib, separated by the distance corresponding to the upper opening of said rib, so as to allow the centering of the profile attached to said rib and on the other hand its fixing by screws 42, the folded parts or tabs 43 of the punctures coming to bear on the upper ends 44 of the inclined blanks 28 of the rib.
