Description

La présente invention se rapporte à un profilé de sup­port en paroi mince ou en tôle pour faîte de toiture dont la section présente la forme générale d'un U en auge et, à proxi­mité du fond de l'auge, une série d'ouvertures de ventilation longitudinales alignées et discontinues, ainsi qu'à un profilé de recouvrement destiné à coopérer avec le profilé de support. Elle concerne également un système de fermeture ventilée de faitage ou d'arêtier de toiture posé sur des éléments de support fixés sur le faîtage de la toiture.The present invention relates to a support profile in thin wall or sheet metal for roof ridge whose section has the general shape of a U in trough and, near the bottom of the trough, a series of openings of aligned and discontinuous longitudinal ventilation, as well as a cover profile intended to cooperate with the support profile. It also relates to a ventilated closure system for roof ridge or hip placed on support elements fixed to the ridge of the roof.

L'architecture moderne tend à utiliser des toits faible­ment inclinés où l'on pallie la faible capacité d'écoulement de l'eau en utilisant des couvertures métalliques à grande capacité d'étanchéité. Ces couvertures étanches et le plus souvent isolées thermiquement favorisent la condensation de la vapeur d'eau sur leurs parties froides et nécessitent, pour éviter cette condensation, l'établissement d'une bonne venti­lation naturelle de faîte. Les ventilations de faîte nécessi­tent des ouvertures pour obtenir un bon écoulement de l'air vers l'extérieur mais aussi des mesures particulières pour éviter la pénétration des intempéries à l'intérieur du bâti­ment en cas de pluie intense par vent violent ou de transport de neige poudreuse.Modern architecture tends to use slightly sloped roofs where the low flow capacity of the water is compensated for by using metal covers with a high sealing capacity. These waterproof and most often thermally insulated covers promote the condensation of water vapor on their cold parts and require, to avoid this condensation, the establishment of good natural ridge ventilation. Ridge ventilation requires openings to obtain good air flow to the outside but also special measures to prevent the penetration of bad weather inside the building in the event of intense rain by strong wind or snow transport. powdery.

La présente invention vise précisément à proposer des moyens simples, esthétiques, efficaces et aisés à mettre en oeuvre pour établir la ventilation de faîte d'une toiture en s'assurant que l'eau des intempéries ne pénètre pas à l'inté­rieur du bâtiment.The present invention aims precisely to provide simple, aesthetic, effective and easy to implement means for establishing the roof ventilation of a roof while ensuring that the water from bad weather does not penetrate inside the building.

A cet effet, au moins l'une des branches du U de la section du profilé de support présente à son extrémité un moyen de fixation et, du côté externe du U, des moyens d'ac­crochage disposés sur la branche du U ou sur le fond du U. Le moyen de fixation est avantageusement constitué par un rebord de la paroi mince ou de la tôle replié vers l'extérieur pour être fixé sur un élément de charpente et les moyens d'accro­chage sont constitués par des crochets fixés à la branche du U entre les ouvertures de ventilation et dont la partie d'accro­chage s'étend en direction de l'extrémité de la branche. Les crochets sont avantageusement montés rotatifs de manière à pouvoir être éloignés du rebord replié à l'extérieur et ils sont montés rotatifs de préférence sur un axe disposé entre deux ouvertures de ventilation voisines disposées de façon sensiblement parallèles au fond de l'auge.To this end, at least one of the branches of the U of the section of the support profile has at its end a fixing means and, on the external side of the U, hooking means arranged on the branch of the U or on the bottom of the U. The fixing means advantageously consists of a rim of the thin wall or of the sheet folded outwards to be fixed on a frame element and the hooking means consist of hooks fixed to the branch U between the ventilation openings and the hooking part of which extends towards the end of the branch. The hooks are advantageously mounted to rotate so as to be able to be moved away from the flange folded out and they are preferably mounted to rotate on an axis disposed between two neighboring ventilation openings arranged substantially parallel to the bottom of the trough.

Selon un autre mode de réalisation du profilé selon l'invention, l'extrémité des crochets est enroulée sur elle­même vers l'extérieur sur un arc légèrement supérieur à 180°, en laissant une ouverture ou zone d'entrée libre constituant une entrée d'encliquetage.According to another embodiment of the profile according to the invention, the end of the hooks is wound on itself towards the outside on an arc slightly greater than 180 °, leaving an opening or free entry area constituting an entry of snap-on.

Le profilé de recouvrement selon l'invention destiné à coopérer avec le profilé de support présente une section transversale en U en forme générale d'auge à au moins une branche élastique dont l'extrémité est enroulée sur elle-même vers l'intérieur du U pour former un bord arrondi d'enclique­tage.The cover profile according to the invention intended to cooperate with the support profile has a U-shaped cross section in the general shape of a trough with at least one elastic branch, the end of which is wound on itself towards the inside of the U to form a rounded snap edge.

Le système de fermeture ventilée de faîtage ou d'arêtier de toiture posé sur des éléments de support fixés sur la charpente de faîte de la toiture, est caractérisé en ce que les éléments de support sont constitués par des profilés de support du type précédent alignés sur le faîte ou l'arêtier et dont la section est disposée en U renversé, le bord replié de la branche du U étant fixé sur des éléments de la toiture de faîte, par exemple des embouts de chevron, tandis que les ouvertures de ventilation de la branche du U sont disposées en partie haute, chaque branche utilisée du U étant recouverte par le pli fortement incliné d'une plaque de tôle de couver­ture moins inclinée, venant se glisser sous les crochets jusqu'au voisinage des ouvertures de ventilation, sans obturer celles-ci et en ce qu'un profilé de recouvrement à section transversale en auge du type décrit précédemment recouvre l'extérieur du profilé en U au voisinage du fond de la section des éléments de support en venant s'encliqueter dans l'ouver­ture de la partie d'accrochage en arc des crochets, par son bord arrondi d'encliquetage pour laisser libre un passage d'air ménagé autour des crochets et relié aux ouvertures de ventilation entre les branches respectives qui se font face du profilé de recouvrement et du profilé de support.The ventilated roof ridge or hip closure system placed on support elements fixed to the roof ridge frame, is characterized in that the support elements consist of support profiles of the previous type aligned on the ridge or the hip and whose section is arranged in an inverted U, the folded edge of the branch of the U being fixed on elements of the ridge roof, for example rafter ends, while the ventilation openings of the branch of the U are arranged in the upper part, each branch used of the U being covered by the strongly inclined fold of a less inclined cover sheet plate, slipping under the hooks to the vicinity of the ventilation openings, without blocking them and in that a cover profile with trough cross section of the type described above covers the outside of the U-shaped profile in the vicinity of the bottom of the section of the support elements by snapping into the opening of the arc-shaped hooking portion of the hooks, by its rounded latching edge to leave free an air passage formed around the hooks and connected to the ventilation openings between the respective branches which face the cover profile and the support profile.

Lorsque les éléments de support sont constitués par des profilés de support à une branche active, alignés sur le faîte et dont la section est posée en U retourné, le bord replié de la branche active est fixé sur des éléments de toiture de faîte tandis que la branche inactive du U est réduite, retour­née vers le haut et fixée au mur et les fentes de ventilation sont placées en partie haute et à l'extérieur du profilé de support au voisinage du fond et recouvert par un profilé de recouvrement du type décrit précédemment mais dont une branche est retournée vers le haut, fixée sur le mur et étanchée par son bord sur le mur et dont l'autre branche qui recouvre les ouvertures de ventilation est encliquetée par son extrémité arrondie dans l'ouverture de la partie d'accrochage en arc des crochets, en laissant libre un passage d'air ménagé autour des crochets et relié aux ouvertures de ventilation entre les branches respectives qui se font face du profilé de recouvre­ment et du profilé de support.When the support elements are constituted by support profiles for an active branch, aligned on the ridge and whose section is laid in an inverted U, the folded edge of the active branch is fixed on ridge roofing elements while the inactive branch of the U is reduced, turned upwards and fixed to the wall and the ventilation slots are placed in the upper part and outside the support profile in the vicinity of the bottom and covered by a cover profile of the type described above but one branch of which is turned upward, fixed to the wall and sealed by its edge on the wall and the other branch of which covers the ventilation openings is snapped in place by its rounded end into the opening of the hooking part in arc of the hooks, leaving free an air passage formed around the hooks and connected to the ventilation openings between the respective branches which face the profile of cover and support profile.

Selon un autre mode de réalisation du système de ferme­ture ventilée selon l'invention, les profilés de support et les profilés de recouvrement sont réalisés en tôle métallique mince résistante aux intempéries, par exemple en tole de zinc ou d'acier inoxydable, les profilés de support étant cloués sur une charpente en bois et les profilés de recouvrement étant uniquement encliquetés par leur bord sur les profilés de support.According to another embodiment of the ventilated closure system according to the invention, the support profiles and the cover profiles are made of thin weather-resistant metal sheet, for example zinc or stainless steel sheet, the profiles of support being nailed to a wooden frame and the cover profiles being only snapped on by their edge on the support profiles.

On a représenté sur la figure 1 les éléments les plus courants utilisés pour réaliser la ventilation du faîte d'une toiture selon l'invention. L'élément principal est constitué par un profilé de support 1 à section en auge ou en U retourné dont au moins l'une des branches 2a et/ou 2b présente à son extrémité un bord replié 3 muni de trous 4 pour sa fixation sur un élément de charpente tel qu'une volige 5 ou une panne (voir la figure 2) à l'aide de vis 6 ou de pointes (non repré­sentées). Le profilé de support 1 présente, au voisinage du fond 7 de l'auge, des ouvertures sous forme de fentes ou lumières longitudinales de ventilation 8 alignées, mais discon­tinues pour maintenir l'intégrité du profilé. Les profilés de support qui doivent résister aux intempéries pendant des années sont de préférence réalisés en tôle métallique mince résistante à la corrosion, par exemple en zinc, en acier inoxydable, mais peuvent également être réalisés en matière plastique résistante. Entre les fentes 8 sont fixés des cro­chets 9 à l'extérieur des branches 2a et 2b, par exemple à l'aide d'un rivet 10. La partie d'accrochage 11 des crochets 9 s'étend normalement en direction du bord replié 3 mais, grâce à la fixation à un seul rivet, on peut faire tourner le cro­chet 9 autour du rivet 10 faisant fonction d'axe de rotation, de manière à éloigner la partie d'accrochage encombrante de la zone repliée de fixation, par exemple pendant sa fixation sur des voltiges ou chevrons 5.The most common elements used to perform ventilation of the roof ridge according to the invention are shown in FIG. 1. The main element is constituted by a support profile 1 with trough or inverted U section, at least one of the branches 2a and / or 2b of which has at its end a folded edge 3 provided with holes 4 for its fixing on a structural element such as a battens 5 or a breakdown (see Figure 2) using screws 6 or spikes (not shown). The support profile 1 has, in the vicinity of the bottom 7 of the trough, openings in the form of slots or longitudinal ventilation slots 8 aligned, but discontinuous to maintain the integrity of the profile. The support profiles which have to withstand the weather for years are preferably made of thin corrosion-resistant metal sheet, for example zinc, stainless steel, but can also be made of material resistant plastic. Between the slots 8 are hooks 9 attached to the outside of the branches 2a and 2b, for example using a rivet 10. The hooking portion 11 of the hooks 9 normally extends towards the folded edge 3 but, thanks to the fixing with a single rivet, the hook 9 can be rotated around the rivet 10 acting as an axis of rotation, so as to move the bulky attachment part away from the folded fixing zone, for example during its attachment to aerobatics or rafters 5.

La partie d'accrochage 11 des crochets 9 est représentée plus en détail et en coupe à la figure 2. On voit que la tôle métallique d'extrémité est ici enroulée sur elle-même en direction de l'extérieur des branches 2a et 2b sur un arc légèrement supérieur à 180° en laissant une entrée libre 12 qui peut recevoir le bord 13, également enroulé sur lui-même mais en sens opposé, d'un profilé de recouvrement 14, en cons­tituant ainsi un système à encliquetage 11, 12, 13. Le profilé de recouvrement 14 présente également une forme d'auge mais à branches plus écartées que l'élément de support 1. Les deux extrémités de rive 13 du profilé de recouvrement en tôle métallique 14 (un profilé sensiblement identique mais réalisé en matière plastique serait également possible) sont enroulées sur elles-mêmes presque sur un cercle fermé (en laissant néanmoins une ouverture pour donner de l'élasticité à l'écra­sement de l'extrémité) pour former un rebord d'encliquetage en saillie.The attachment portion 11 of the hooks 9 is shown in more detail and in section in FIG. 2. It can be seen that the end metal sheet is here wound on itself towards the outside of the branches 2a and 2b on an arc slightly greater than 180 °, leaving a free entry 12 which can receive the edge 13, also wound on itself but in the opposite direction, of a covering profile 14, thus constituting a snap system 11, 12, 13. The cover profile 14 also has a trough shape but with branches more spaced apart than the support element 1. The two edge ends 13 of the sheet metal cover profile 14 (a profile that is substantially identical but made of material plastic would also be possible) are wound on themselves almost on a closed circle (nevertheless leaving an opening to give elasticity to the crushing of the end) to form a rim protruding ratchet.

Le système de fermeture ventilée réalisé à l'aide des composants de la figure 1 est représenté en cours de pose à la figure 2. Les profilés de support 1 étant fixés bout-à-bout sur les deux extrémités des voltiges 5 et 5a par des vis ou pointes 6, ils forment sur toute leur longueur une chambre collectrice supérieure 15 munie d'ouvertures de ventilation 8 à sa partie haute. Les crochets 9 étant retournés vers le haut pour dégager les branches 2a et 2b, on place selon la pente du toit des bacs 16 collecteurs de pluie et de neige, étanchés entre eux par des tasseaux 17 et munis d'un pli 18 à forte pente qui vient s'appliquer sur les branches 2a ou respecti­vement 2b jusqu'à proximité des fentes de ventilation 8.The ventilated closure system produced using the components of FIG. 1 is shown during installation in FIG. 2. The support profiles 1 being fixed end-to-end on the two ends of the aerobatics 5 and 5a by screws or points 6, they form over their entire length an upper collecting chamber 15 provided with ventilation openings 8 at its upper part. The hooks 9 being turned upward to release the branches 2a and 2b, we place according to the slope of the roof of the trays 16 rain and snow collectors, sealed between them by cleats 17 and provided with a fold 18 with a steep slope which is applied to the branches 2a or 2b respectively until near the ventilation slots 8.

Pour éviter la remontée de la pluie par vent violent jusque dans la chambre collectrice 15 à travers les fentes 8, le support tubulaire constitué par les éléments de support 1 mis bout-à-bout ou superposés sur une faible longueur à leur extrémité est coiffé de l'élément de recouvrement 14 après orientation des crochets 9 vers le bas au-dessus des plis 18. Les bords enroulés 13 de l'élément 14 sont engagés dans les ouvertures 12 et forcés à l'intérieur des crochets 11 où ils restent emprisonnés par un puissant effet d'encliquetage utilisant l'élasticité réciproque des bords 13 et des parties d'accrochage 11. Un canal d'évacuation 19 permettant à l'air de ventilation de s'écouler vers le bras est ainsi formé entre les branches parallèles du profilé de recouvrement 14 et les branches 2a et 2b du profilé de support 1. Le trajet d'écou­lement de l'air de ventilation est représenté par des flè­ches 20 et 21. La flèche 21 indique le circuit de ventilation le plus général de l'intérieur du batiment vers l'extérieur. L'élément de recouvrement 14 étane très fortement retenu sur les crochets 9 ne peut être arraché par le vent et ne risque pas de s'oxyder car il est réalisé en un métal résistant à la corrosion (par exemple en zinc) appliqué sur des crochets également en métal noble et résistant, par exemple en acier inoxydable.To avoid the rise of rain in strong wind into the collecting chamber 15 through the slots 8, the tubular support constituted by the support elements 1 placed end to end or superimposed on a short length at their end is capped with the covering element 14 after orientation of the hooks 9 downwards above the folds 18. The rolled edges 13 of the element 14 are engaged in the openings 12 and forced inside the hooks 11 where they remain trapped by a powerful snap-on effect using the reciprocal elasticity of the edges 13 and the hooking parts 11. An exhaust channel 19 allowing the ventilation air to flow towards the arm is thus formed between the parallel branches of the cover profile 14 and the branches 2a and 2b of the support profile 1. The flow path of the ventilation air is represented by arrows 20 and 21. The arrow 21 indicates the fan circuit most general from the inside of the building to the outside. The covering element 14 etane very strongly retained on the hooks 9 cannot be torn off by the wind and is not likely to oxidize because it is made of a metal resistant to corrosion (for example zinc) applied to hooks also in noble and resistant metal, for example stainless steel.

Dans le cas où la toiture est adossée à un mur 22, comme représentée à la figure 3, le profilé de support la doit être modifié de façon à ne conserver que la moitié de la forme en U aved une seule branche active 23. La branche inactive 24 du U est réduite, retournée vers le haut et est fixée (par exemple par des vis 25) sur le mur 22. le profilé de recouvrement 14a subit un traitement similaire, sa branche inactive 26 étant retournée vers le haut, fixée au mur 22, par exemple par des vis 27, et étanchée en bordure sur le mur 22 par une couche adhésive 28. Un seul canal de ventilation inversé 19a est créé entre la branche active du profilé de recouvrement 14a et al branche 23 du profilé de support modifié 1a. Le canal 19a permet d'assurer un parcours d'air de ventilation 29 identique à celui obtenu pour le troit à deux pentes. On remarquera que la branche inactive 26 présente à sa partie supérieure un rebord replié 30 qui retient pendant le temps de prise un mastic très adhérent pour réaliser la couche adhésive d'étan­chéité 28 interdisant pendant une longue durée toute pénétra­tion d'eau en dessous du fond 7 de l'auge, le long du mur 22.In the case where the roof is backed by a wall 22, as shown in FIG. 3, the support profile 1a must be modified so as to keep only half of the U shape with a single active branch 23. The branch inactive 24 of the U is reduced, turned upwards and is fixed (for example by screws 25) to the wall 22. the cover profile 14a undergoes a similar treatment, its inactive branch 26 being turned upwards, fixed to the wall 22, for example by screws 27, and sealed at the edge on the wall 22 by an adhesive layer 28. A single inverted ventilation channel 19a is created between the active branch of the cover profile 14a and al branch 23 of the modified support profile 1a. The channel 19a ensures a ventilation air path 29 identical to that obtained for the troit with two slopes. It will be noted that the inactive branch 26 has at its upper part a folded rim 30 which retains during the setting time a very adherent mastic for producing the adhesive sealing layer 28 preventing for a long time any penetration of water below the bottom 7 of the trough, along the wall 22.

Dans le système de fermeture ventilée pour un toit mono­pente représenté à la figure 4, on utilise pour l'élément de support 1b une section identique à celle de la figure 3, à la seule différence que la branche inactive 31 du U est dirigée vers le bas; l'élément de recouvrement 14 est identique à celui des figures 1 et 2 dans le cas d'un toit à deux pentes. Afin de retenir correctement en position l'élément de sup­port 1b qui ne peut s'appuyer que d'un côté par son bord 3 sur le chevron 5, on prévoit un support vertical en bois 32, posé par exemple sur une poutre de support de chevrons 33 (qui peut être, le cas échéant, remplacée par une façade de mur). Le fond 7 de l'auge de l'élément de support 1b est posé sur la face d'extrémité 34 du support 32 et est fixé sur ce support, par exemple par des vis 35. Un bardage 36 qui prolonge la branche 31 peut venir se glisser sous la branche extérieure 37 du profilé de recouvrement 14.In the ventilated closure system for a single-slope roof shown in FIG. 4, the support element 1b is used with a section identical to that of FIG. 3, with the only difference that the inactive branch 31 of the U is directed towards the low; the covering element 14 is identical to that of FIGS. 1 and 2 in the case of a roof with two slopes. In order to correctly retain in position the support element 1b which can only bear on one side by its edge 3 on the rafter 5, a vertical wooden support 32 is provided, placed for example on a support beam rafters 33 (which can be replaced, if necessary, by a wall facade). The bottom 7 of the trough of the support element 1b is placed on the end face 34 of the support 32 and is fixed to this support, for example by screws 35. A cladding 36 which extends the branch 31 may come slide under the outer branch 37 of the cover profile 14.
