Description

La présente invention concerne le domaine des constructions à structure ou ossature dites "légères", c'est-à-dire comportant un squelette métallique ou en bois sur lequel sont montés les parois latérales extérieures et le toit, à la différence des constructions dites massives, c'est-à-dire en briques, en béton, en pierres ou analogues.The present invention relates to the field of constructions with structure or frame called "light", that is to say comprising a metal or wooden skeleton on which are mounted the outer side walls and the roof, unlike so-called massive constructions that is, brick, concrete, stone, or the like.

Toutefois, l'invention peut également concerner un bâtiment composite, c'est-à-dire dont seulement une partie est à structure ou ossature légère, seule cette partie étant alors concernée par l'invention.However, the invention may also relate to a composite building, that is to say of which only a part is of structure or light frame, only this part then being concerned by the invention.

L'invention concerne plus particulièrement les bâtiments fermés, à vocation résidentielle (individuelle ou collective), industrielle ou tertiaire, présentant à la base une bonne isolation thermique.The invention relates more particularly to closed buildings, residential (individual or collective), industrial or tertiary, having at the base a good thermal insulation.

Les parois de ce type de bâtiments présentent généralement une constitution composite à plusieurs couches avec, de l'intérieur vers l'extérieur : une composante surfacique rigide à base de panneaux ou de plaques formant une structure de paroi continue, une ou plusieurs couches de matériau isolant thermique, et le cas échéant phonique, et une couche de parement ou peau extérieure. De manière alternative, la composante surfacique rigide à base de panneaux ou de plaques (ou plateaux) peut être disposée entre la ou les couches isolantes et le parement extérieur, comme par exemple les panneaux de contreventement extérieurs en bois dans le cas d'un bâtiment à ossature en bois. Des couches d'isolation additionnelles ou une ossature complémentaire peuvent en outre être prévues.The walls of this type of building generally have a multilayer composite structure with, from the inside to the outside: a rigid surface component based on panels or plates forming a continuous wall structure, one or more layers of material thermal insulation, and if necessary phonic, and a cladding layer or outer skin. Alternatively, the rigid surface component based on panels or plates (or trays) can be arranged between the insulation layer (s) and the external facing, such as, for example, wooden external bracing panels in the case of a building. wooden frame. Additional insulation layers or a complementary framework may further be provided.

Bien que ce type de bâtiment présente a priori une isolation thermique satisfaisante du point de vue des moyens et matériaux mis en oeuvre, il existe une demande pressante pour réduire sensiblement les consommations et/ou les coûts de chauffage/climatisation de tels bâtiments.Although this type of building has a priori satisfactory thermal insulation from the point of view of the means and materials used, there is a pressing demand to significantly reduce the consumption and / or heating / cooling costs of such buildings.

Or, les inventeurs ont constaté que les déperditions sont en partie, voire majoritairement (de 10 à 15 % pour les bâtiments résidentiels, et jusqu''a 75 % dans certains cas de bâtiments non résidentiels) liées à des fuites d'air non contrôlées à travers l'enveloppe du bâtiment (distinctes des flux d'air échangés de manière contrôlée à des fins de renouvellement d'air, par exemple par circulation à double flux).However, the inventors have found that part or even the majority of losses (from 10 to 15% for residential buildings, and up to 75% in some cases of non-residential buildings) are related to uncontrolled air leaks. through the building envelope (distinct from air flows exchanged in a controlled manner for air renewal purposes, for example by double-flow circulation).

En outre, il existe également une demande pour la réalisation d'une enveloppe de bâtiment provisoire, au moins hors d'eau, qui permet d'effectuer les travaux d'aménagement ou d'équipement complémentaires et les travaux de finition sans nécessiter de coordination des travaux intérieurs et extérieurs entre eux, ni des corps de métier intervenant pour leur réalisation (obtention d'une barrière temporaire non définitive permettant de déconnecter suffisamment les environnements intérieur et extérieur pour autoriser des évolutions/aménagements indépendants et différents sur les faces intérieures et extérieures du bâtiment).In addition, there is also a demand for the realization of a temporary building envelope, at least out of water, which allows to carry out the development work or complementary equipment and finishing work without requiring coordination internal and external work between them, or trades involved in their implementation (obtaining a non-definitive temporary barrier to sufficiently disconnect the indoor and outdoor environments to allow evolutions / independent and different arrangements on the inner and outer faces of the building).

De plus, l'étanchéité et l'isolation du bâtiment devraient être conçues pour pouvoir être aisément confiées à un seul prestataire et la solution mise en oeuvre devrait être fiable dans le temps.In addition, the watertightness and insulation of the building should be designed so that it can be easily entrusted to a single provider and the solution implemented should be reliable over time.

Par le document US 2002/164447 , on connaît déjà un bâtiment selon le préambule de la revendication 1.By the document US 2002/164447 a building according to the preamble of claim 1 is already known.

Le but de l'invention est de proposer un bâtiment du type précité avec une couche additionnelle formant un écran sensiblement étanche à l'eau et à l'air et perméable à la vapeur, qui est solidement supportée et dont la réalisation et l'étanchéification de l'assemblage de ses bandes constitutives sont simples à exécuter.The object of the invention is to provide a building of the aforementioned type with an additional layer forming a substantially watertight and airtight and vapor-permeable screen, which is firmly supported and the production and sealing of which the assembly of its constituent strips are simple to perform.

En outre, l'écran 7 étant étanche à l'eau, il est possible d'obtenir un élément d'ouvrage étanche sur sa face extérieure et formant écran imperméable contre les agents atmosphériques.In addition, the screen 7 being waterproof, it is possible to obtain a waterproof workpiece on its outer face and forming a screen impermeable against atmospheric agents.

Dans la présente, le terme "paroi latérale" vise essentiellement des parois verticales délimitant l'enceinte périphérique d'un bâtiment. Toutefois, l'invention peut également s'appliquer à des parois inclinées, voire en pente.In the present, the term "side wall" is essentially vertical walls delimiting the peripheral enclosure of a building. However, the invention can also be applied to inclined or sloping walls.

En outre, comme déjà indiqué précédemment, l'invention concerne un bâtiment 22 dans sa totalité, c'est-à-dire dont toutes les parois latérales 10 sont formées par des dispositifs de paroi 1.In addition, as already indicated above, the invention relates to a building 22 in its entirety, that is to say of which all the side walls 10 are formed by wall devices 1.

Comme l'illustrent les figures 1 et 12, le ou chaque dispositif de paroi 1 selon l'invention peut se présenter sous deux modes de réalisation qui diffèrent par le positionnement relatif de la couche isolante 4 et de la structure de paroi 3' continue et rigide.As illustrated by figures 1 and 12 , the or each wall device 1 according to the invention can be in two embodiments which differ by the relative positioning of the insulating layer 4 and the wall structure 3 'continuous and rigid.

En effet, la couche isolante 4 peut être située, soit sur la face extérieure de la structure de paroi 3' (figures 1 à 11), soit sur la face intérieure de cette dernière (figure 12).Indeed, the insulating layer 4 may be located on the outer face of the wall structure 3 '( Figures 1 to 11 ), or on the inside of the latter ( figure 12 ).

La première variante constructive des parois 10 (figures 1 à 11) est normalement mieux adaptée à des bâtiments à ossature métallique 2 et à plateaux métalliques 3, alors que la seconde variante (figure 12) trouve une application privilégiée dans les bâtiments à ossature bois 2 et à panneaux en bois 3 (une couche de parement intérieure 21 peut éventuellement être prévue).The first constructive variant of the walls 10 ( Figures 1 to 11 ) is normally better suited to buildings with metal framework 2 and metal plates 3, while the second variant ( figure 12 ) finds a preferred application in wood frame buildings 2 and wood panels 3 (an inner cladding layer 21 may optionally be provided).

La description qui suit, ainsi que les dessins annexés, portent plus particulièrement sur la première variante constructive (ordre des couches : 3', 4, 7, 5), mais les caractéristiques et avantages mentionnés s'appliquent bien entendu également à la seconde variante (ordre des couches : 4, 3', 7, 5).The description which follows, as well as the appended drawings, relate more particularly to the first constructive variant (order of the layers: 3 ', 4, 7, 5), but the characteristics and advantages mentioned apply, of course, also to the second variant (order of layers: 4, 3 ', 7, 5).

Conformément à l'invention, les bandes d'écran 7' consistent en des bandes d'écran présentant une étanchéité élevée à l'eau, une haute étanchéité à l'air, une haute perméabilité à la vapeur d'eau et une bonne résistance à la déchirure, telles que par exemple des bandes d'écran de sous-toiture ou d'écran pare-pluie, ces bandes d'écran 7' étant aptes à être soudées ensemble par simple apport calorique, sans moyen ou substance additionnel(le), par exemple par soudure à l'air chaud, au niveau de portions latérales de bandes mutuellement chevauchantes 7"'.According to the invention, the screen strips 7 'consist of screen strips having high water tightness, high airtightness, high water vapor permeability and good resistance at tear, such as for example strips of under-roof screen or rain screen, these screen strips 7 'being able to be welded together by simple caloric intake, without means or additional substance (the ), for example by hot air welding, at lateral portions of mutually overlapping strips 7 "'.

Préférentiellement, ces bandes d'écran 7' sont soudables sur chantier ou site, notamment par l'intermédiaire d'un pistolet à air chaud ou analogue connu de l'homme du métier.Preferably, these screen strips 7 'are weldable on site or site, in particular by means of a hot air gun or the like known to those skilled in the art.

Le liaisonnement des bandes d'écran 7' par soudure, préférentiellement avec chevauchement latéral partiel entre bandes 7', permet d'obtenir un assemblage continu de ces bandes, sans matériau d'apport, sans nécessiter de pièces de liaison rapportées et en étant fiable dans le temps.The bonding of the screen strips 7 'by welding, preferably with partial lateral overlap between the strips 7', makes it possible to obtain a continuous assembly of these strips, without filler material, without the need for reported connection pieces and being reliable in time.

De plus, une telle possibilité d'assemblage des bandes 7' permet de conserver l'ensemble des propriétés intrinsèques desdites bandes 7' au niveau de la totalité de l'écran 7 (étanchéité à l'eau et à l'air, perméabilité à la vapeur d'eau, bonne résistance à la déchirure).In addition, such an assembly possibility strips 7 'keeps all the intrinsic properties of said strips 7' at the entire screen 7 (water and air tightness, permeability to water vapor, good resistance to tearing).

Les bandes d'écran 7' peuvent consister en des bandes d'écran de sous-toiture conforme à la norme NF EN 13859-1 ou d'écran pare-pluie conforme à la norme NF EN 13859-2.The screen strips 7 'may consist of under-roof screen strips in accordance with standard NF EN 13859-1 or rain screen in accordance with the standard NF EN 13859-2.

A titre d'exemples illustratifs et non limitatifs de leurs caractéristiques techniques, les bandes 7' constituant la couche additionnelle 7 peuvent faire état :

  • d'un classement W1 ou W2 (norme EN 13859) en ce qui concerne le critère d'étanchéité à l'eau ;
  • d'une perméabilité à l'air inférieure à 0,2 m3/m2.h, préférentiellement inférieure à 0,1 m3/m2.h, sous une pression de 50 Pa et selon la norme NF EN 12114 ;
  • d'une perméabilité à la vapeur d'eau avec une valeur Sd inférieure ou égale à 50 cm, avantageusement inférieure ou égale à 30 cm, préférentiellement inférieure ou égale à 18 cm, selon la norme NF EN 12572 ;
  • d'une résistance à la déchirure au clou supérieure à 70 N, préférentiellement supérieure à 150 N, selon la norme NF EN 12310-1.
By way of illustrative and non-limiting examples of their technical characteristics, the strips 7 'constituting the additional layer 7 may show:
  • a W1 or W2 classification (EN 13859) with regard to the watertightness criterion;
  • a permeability to air of less than 0.2 m 3 / m 2 .h, preferably less than 0.1 m 3 / m 2 .h, at a pressure of 50 Pa and according to standard NF EN 12114;
  • a permeability to water vapor with a value Sd less than or equal to 50 cm, advantageously less than or equal to 30 cm, preferably less than or equal to 18 cm, according to standard NF EN 12572;
  • a tear strength to the nail greater than 70 N, preferably greater than 150 N, according to the standard NF EN 12310-1.

Ces bandes 7' peuvent, par exemple, correspondre à des bandes d'écran de sous-toiture commercialisées par la demanderesse sous la désignation "Soplutec", ou encore à des bandes d'écran de sous-toiture commercialisées par la demanderesse sous la désignation "Stratec" pour les ouvrages de couverture ou des bandes d'écran pare-pluie commercialisées par la demanderesse sous la désignation "Stratec Façade" pour les parois verticales.These strips 7 'may, for example, correspond to sub-roofing screen strips sold by the applicant under the designation "Soplutec", or to strips of under-roof screen marketed by the applicant under the designation "Stratec" for roofing works or rainscreen strips marketed by the applicant under the designation "Stratec Façade" for the vertical walls.

Selon un mode de réalisation pratique avantageux, en rapport avec le premier mode de réalisation de l'invention, les bandes d'écran 7' et la couche d'isolation thermique 4 sont solidarisées avec les éléments surfaciques 3 par l'intermédiaire de vis de fixation 8 traversant ladite couche d'isolation thermique 4 et venant s'ancrer dans des nervures ou lèvres 3" en saillie vers l'extérieur de la structure de paroi 3', par exemple formées par les bords en contact des éléments surfaciques 3, des moyens d'étanchéification 8' étant prévus au niveau de chaque vis 8.According to an advantageous practical embodiment, in connection with the first embodiment of the invention, the screen strips 7 'and the thermal insulation layer 4 are secured to the surface elements 3 by means of screws. fastening 8 passing through said thermal insulation layer 4 and coming to anchor in ribs or lips 3 "protruding outwards from the wall structure 3 ', for example formed by the edges in contact with the surface elements 3, sealing means 8 'being provided at each screw 8.

Les moyens d'étanchéification 8' peuvent consister en des portions de bandes d'étanchéité bitumineuses ou d'un autre matériau membranaire à liant mou (non tissé ou laminé non tissé enduit), aptes à être traversées par les vis 8 en étanchéifiant le filetage de ces dernières (par exemple des portions de bandes de matériau du type commercialisé sous la désignation "Soprasolin" par la demanderesse).The sealing means 8 'may consist of portions of bituminous sealing strips or of another soft-binder membrane material (non-woven or non-woven laminated coating), able to be traversed by the screws 8 by sealing the threading of the latter (for example portions of strips of material of the type marketed under the designation "Soprasolin" by the Applicant).

Dans le mode de réalisation de la figure 12, les bandes d'écran 7 peuvent être soit collées, soit fixées mécaniquement sur les panneaux 3' de la structure de paroi continue 3.In the embodiment of the figure 12 , the screen strips 7 may be glued or mechanically fixed to the panels 3 'of the continuous wall structure 3.

Afin d'augmenter les propriétés isolantes du, de certains ou de chaque dispositif de paroi 1 selon l'invention, le bâtiment 22 peut comprendre, comme cela ressort des figures 1, 3A et 5 à 7 notamment des dessins annexés, une couche secondaire d'isolation thermique et/ou phonique 9 disposée entre l'écran continu 7 et la couche de parement ou peau extérieure 5, le cas échéant avec formation d'une lame d'air 9' entre lesdites couche 5 et 9. Les éléments constitutifs 6' de l'ossature secondaire 6, par exemple sous forme de profilés à section en Ω, sont intégrés dans ladite couche secondaire d'isolation 9 et fixés aux éléments surfaciques ou plateaux 3 de la structure de paroi 3', par exemple par l'intermédiaire des vis 8 de fixation de l'écran continu 7 et de la couche d'isolation thermique 4.In order to increase the insulating properties of, some or each wall device 1 according to the invention, the building 22 may comprise, as is apparent from the figures 1 , 3A and 5 to 7 in particular appended drawings, a secondary thermal and / or sound insulation layer 9 disposed between the continuous screen 7 and the facing layer or outer skin 5, where appropriate with the formation of an air gap 9 'between said layer 5 and 9. The constituent elements 6 'of the secondary framework 6, for example in the form of Ω section profiles, are integrated in said secondary insulation layer 9 and fixed to the surface elements or plates 3 of the structure of wall 3 ', for example by means of screws 8 for fixing the continuous screen 7 and the thermal insulation layer 4.

En variante, et comme le montre la figure 3B, la couche isolante additionnelle 9 peut également être disposée intérieurement.Alternatively, and as shown in figure 3B the additional insulating layer 9 may also be disposed internally.

Dans ce cas, le bâtiment 22 peut comprendre, au niveau du ou d'au moins un dispositif de paroi 1, une couche secondaire ou additionnelle d'isolation thermique et/ou phonique 9 installée contre la face interne des éléments surfaciques 3 formant la structure de paroi continue 3', ladite couche isolante interne additionnelle 9 étant recouverte ou doublée intérieurement d'une couche structurelle et/ou décorative autoportante 9", par exemple formée de panneaux ou de plaques de plâtre ou analogues (figure 1B).In this case, the building 22 may comprise, at the level of the or at least one wall device 1, a secondary or additional layer of thermal and / or sound insulation 9 installed against the internal face of the surface elements 3 forming the structure. continuous wall 3 ', said additional internal insulating layer 9 being covered or lined internally with a self-supporting structural and / or decorative layer 9 ", for example formed of panels or plasterboard or the like ( Figure 1B ).

Bien entendu, les deux variantes précitées peuvent éventuellement être panachées entre les différentes parois 10.Of course, the two aforementioned variants may optionally be variegated between the different walls 10.

L'état intermédiaire de construction (après mise en place de l'écran 7 - voir figures 2 et 4), avec mise hors d'eau du bâtiment 2 et mise en place d'une étanchéité à l'air au moins au niveau des parois 10, sera sensiblement identique pour les deux variantes.The intermediate state of construction (after setting up the screen 7 - see figures 2 and 4 ), with out of water of the building 2 and implementation of an airtightness at least at the walls 10, will be substantially identical for both variants.

Le choix définitif de la mise en place intérieure ou extérieure de la couche 9 peut encore être effectué après la phase intermédiaire précitée.The final choice of the internal or external placement of the layer 9 can be made after the intermediate phase mentioned above.

Le cas échéant, au moins certaines des parois 10 peuvent présenter des couches 9 intérieure et extérieure (non représenté).Where appropriate, at least some of the walls 10 may have inner and outer layers 9 (not shown).

Comme cela ressort des figures 8 et 9 des dessins annexés, le bâtiment 22 peut comporter, au niveau du ou de chaque dispositif de paroi 1, au moins une baie ou au moins une ouverture de passage 16 délimitée par un cadre dormant 16' d'un dispositif de fenêtre, porte ou analogue, l'écran continu 7 étant solidarisé de manière continue, par exemple par collage, par raccordement ou fixation mécanique, par exemple par pincement ou raccordement au moyen d'un profilé 17, audit ou à chacun desdits dormant(s) 16'.As is apparent from figures 8 and 9 In the appended drawings, the building 22 may comprise, at the level of the or each wall device 1, at least one bay or at least one passage opening 16 delimited by a fixed frame 16 'of a window device, door or the like. , the continuous screen 7 being secured in a continuous manner, for example by gluing, by mechanical connection or fixing, for example by pinching or connection by means of a profile 17, audit or each of said frame (s) 16 '.

De même, comme le montrent les figures 6, 10 et 11, ledit écran 7 est également solidarisé de manière continue, par collage, soudure ou fixation mécanique, aux éléments 2' de l'ossature primaire 2 entourant ledit dispositif de paroi 1 concerné, au bord ou longeron périphérique de la dalle 18, du socle, du soubassement ou analogue et, le cas échéant, à l'écran 7 d'un autre dispositif de paroi latérale 1 attenant.Similarly, as shown by figures 6 , 10 and 11 said screen 7 is also secured in a continuous manner, by bonding, welding or mechanical fixing, to the elements 2 'of the primary framework 2 surrounding said wall device 1 concerned, at the peripheral edge or edge of the slab 18, of the base, basement or the like and, if appropriate, the screen 7 of another adjoining sidewall device 1.

L'homme du métier comprend que ces différentes mesures, dont la mise en oeuvre pratique ne nécessite pas de description plus détaillée, permettent d'étendre les propriétés particulières du ou de chaque dispositif de paroi 1 découlant notamment de l'écran 7 aux interfaces de raccordement raccordement dudit dispositif de paroi 1 avec les équipements qu'il intègre ou les composantes structurelles auxquelles il est relié.Those skilled in the art understand that these various measurements, the practical implementation of which does not require a more detailed description, make it possible to extend the particular properties of the or each wall device 1 resulting in particular from the screen 7 at the interfaces of FIG. connection connecting said wall device 1 with the equipment it incorporates or the structural components to which it is connected.

En vue de diminuer davantage encore le risque de condensation dans la couche isolante 4 et/ou d'améliorer les caractéristiques acoustiques de la paroi (notamment lorsque les panneaux ou plateaux 3 sont perforés), un écran pare-vapeur 19 peut être disposé entre la couche d'isolation 4 et la structure de paroi continue 3', en étant éventuellement solidarisé à cette dernière, au niveau du ou de chaque dispositif de paroi 1 du bâtiment 22.In order to further reduce the risk of condensation in the insulating layer 4 and / or to improve the acoustic characteristics of the wall (especially when the panels or trays 3 are perforated), a vapor barrier 19 may be placed between the insulation layer 4 and the continuous wall structure 3 ', possibly being secured to the latter, at the or each wall device 1 of the building 22.

Un tel écran pare-vapeur peut éventuellement consister en un écran du type tel que décrit dans le document EP 1 046 760 ou commercialisé par la demanderesse sous la désignation "Sopravap stick alu", ou encore un produit équivalent non bitumineux.Such a vapor barrier screen may possibly consist of a screen of the type as described in the document EP 1 046 760 or marketed by the applicant under the designation "Sopravap stick aluminum", or a non-bituminous equivalent product.

Selon l'invention, toutes les parois latérales 10 du bâtiment selon l'invention consistent en des dispositifs de paroi 1 tel que décrits ci-dessus et représentés aux dessins annexés, ces parois 10 formant avec le toit 10' une enveloppe de bâtiment étanche à l'eau, sensiblement étanche à l'air et perméable à la vapeur d'eau.According to the invention, all the side walls 10 of the building according to the invention consist of wall devices 1 as described above and shown in the accompanying drawings, these walls 10 forming with the roof 10 'a waterproof building envelope to water, substantially airtight and permeable to water vapor.

Dans sa version finalisée, à la différence de son état de réalisation intermédiaire (après mise en place de l'écran 7), l'étanchéité à l'eau du bâtiment résultera essentiellement de la couche de parement ou peau extérieure 5, l'écran 7 contribuant alors, sauf circonstances exceptionnelles, uniquement à l'étanchéité à l'air et à la perméabilité à la vapeur d'eau de l'enveloppe du bâtiment.In its finalized version, unlike its intermediate embodiment (after placement of the screen 7), the waterproofness of the building will result essentially from the facing layer or outer skin 5, the screen 7 contributing, except in exceptional circumstances, only to airtightness and water vapor permeability of the building envelope.

Comme le montre la figure 7 des dessins annexés, la continuité des différentes composantes constitutives de chacune des parois latérales 10 sous forme de dispositif de paroi 1 est assurée au niveau des arêtes de jonction entre ces parois 10. En particulier, l'écran 7 présente une continuité structurelle au niveau de ses jonctions.As shown in figure 7 In the accompanying drawings, the continuity of the various constituent components of each of the side walls 10 in the form of a wall device 1 is provided at the junction edges between these walls 10. In particular, the screen 7 has a structural continuity at the level of its junctions.

Conformément à l'invention et comme le montrent les figures 3, 5 et 6 des dessins annexés, le toit 10' est constitué d'une structure de paroi continue porteuse 11 recouverte d'un complexe d'isolation et d'étanchéification 12, 12', ce dernier comportant en sous-face un écran pare-vapeur 13 lequel est relié de manière continue et étanche à l'écran continu 7 étanche à l'air et à l'eau et perméable à la vapeur d'eau, intégré dans les parois latérales 10.According to the invention and as shown by figures 3 , 5 and 6 In the accompanying drawings, the roof 10 'consists of a continuous supporting wall structure 11 covered with an insulation and sealing complex 12, 12', the latter comprising on the underside a vapor barrier 13 which is continuously and tightly connected to the continuous screen 7 sealed to water and water and permeable to water vapor, integrated into the side walls 10.

Avantageusement, cet écran pare-vapeur 13 présente également des propriétés d'étanchéité à l'air, à l'instar de l'écran 7, mais éventuellement à un degré différent.Advantageously, this vapor barrier screen 13 also has airtightness properties, like the screen 7, but possibly to a different degree.

Selon une variante constructive de l'invention représentée aux figures 3A, 3B et 4 des dessins annexés, les bandes 7' de l'écran 7 formant la couche additionnelle faisant partie des parois latérales 10 se prolongent au niveau des bords supérieurs 10" de ces parois 10 par des portions 14 formant retours et recouvrant lesdits bords 10".According to a constructive variant of the invention shown in Figures 3A , 3B and 4 In the accompanying drawings, the strips 7 'of the screen 7 forming the additional layer forming part of the side walls 10 extend at the upper edges 10 "of these walls 10 by portions 14 forming returns and covering said edges 10".

Comme le montrent également ces figures, l'écran pare-vapeur 13 en sous-face du complexe d'isolation et d'étanchéification 12, 12' se prolonge latéralement par des portions 13' formant galons de recouvrement, ces derniers s'étendant par-dessus les portions supérieures formant retours 14 de l'écran 7 des parois latérales, jusqu'à dépasser au-delà desdits retours 14 et le long de la face extérieure dudit écran 7.As also shown in these figures, the vapor barrier screen 13 on the underside of the insulation and sealing complex 12, 12 'is laterally extended by portions 13' forming cover strips, the latter extending by above the upper portions forming returns 14 of the screen 7 of the side walls, to exceed beyond said returns 14 and along the outer face of said screen 7.

Avantageusement, les portions 14 formant retours sont fixées mécaniquement sur les plateaux ou panneaux 3 des structures de paroi continues 3' des parois latérales 10 délimitant les bords supérieurs 10" de ces derniers et les galons de recouvrement 13' de l'écran pare-vapeur 13 sont assemblés par soudure, collage ou adhésion à froid continu(e) avec lesdites portions 14 formant retours, ce en fonction du type de l'écran pare-vapeur 13, ce dernier pouvant éventuellement être du même type que le pare-vapeur 19 précité.Advantageously, the portions 14 forming returns are mechanically fixed to the trays or panels 3 of the continuous wall structures 3 'of the side walls 10 delimiting the upper edges 10 "of the latter and the cover strips 13' of the vapor barrier 13 are assembled by welding, gluing or continuous cold adhesion (e) with said portions 14 forming returns, depending on the type of the vapor barrier 13, the latter possibly being of the same type as the vapor barrier 19 supra.

En vue de pouvoir fournir un bâtiment hors d'eau avant les travaux de finition extérieurs, en particulier avant la mise en place des éléments de parement (couvertine 20 et contre-parement ou contre-bardage 20' par exemple faisant partie de l'acrotère) destinés à recouvrir les bords périphériques supérieurs du bâtiment (zone de jonction entre les parois latérales 10 et le toit 10'), il peut être prévu que les parties latérales 12" de la couche isolante 12 du complexe 12, 12' s'étendant au-dessus des bords supérieurs 10" des parois latérales 10 et non couvertes par la ou les couche(s) 12' formant la composante superficielle d'étanchéité dudit complexe 12, 12' sont recouvertes par des portions d'écran pare-pluie 15, retombant librement au-delà des bords supérieurs 10" des parois latérales 10 et des galons de recouvrement 13' de l'écran pare-vapeur 13 (figure 3A). Ces portions d'écran 15 peuvent éventuellement ne réaliser qu'une étanchéité provisoire et transitoire dans une phase constructive intermédiaire (figure 3B).In order to be able to provide a building out of water before the exterior finishing work, in particular before the placement of the facing elements (roofing 20 and counter-facing or counter-cladding 20 'for example forming part of the acroterium ) intended to cover the upper peripheral edges of the building (junction zone between the side walls 10 and the roof 10 '), it may be provided that the lateral portions 12 "of the insulating layer 12 of the complex 12, 12' extending above the upper edges 10 "of the side walls 10 and not covered by the layer (s) 12 'forming the surface sealing component of said complex 12, 12' are covered by portions of rain screen 15 , falling freely beyond the upper edges 10 "of the side walls 10 and the cover strips 13 'of the vapor barrier screen 13 ( figure 3A ). These screen portions 15 may possibly achieve only temporary and transient sealing in an intermediate constructive phase ( figure 3B ).

Selon une autre variante constructive de l'invention représentée à la figure 5 des dessins annexés, les bandes 7' de l'écran 7 formant la couche additionnelle des parois latérales 10 se prolongent au niveau des bords supérieurs 10" de ces parois 10 par des portions 14 formant retours, qui recouvrent lesdits bords supérieurs 10" et s'étendent partiellement par-dessus la structure de paroi continue porteuse 11 et l'écran pare-vapeur 13 porté par cette structure 11 (par exemple formée d'éléments du type bac acier). Ces portions 14 sont assemblées continûment directement par soudure, collage ou adhésion à froid, ou indirectement par l'intermédiaire d'une membrane d'étanchéité (le cas échéant avec formation d'un relevé d'étanchéité) à l'écran pare-vapeur 13, ce en fonction de la nature de ce dernier, lesdites portions 14 se prolongeant au moins jusqu'à être situées sous la ou les couche(s) 12' formant la composante superficielle d'étanchéité du complexe 12, 12'.According to another constructive variant of the invention shown in figure 5 In the accompanying drawings, the strips 7 'of the screen 7 forming the additional layer of the side walls 10 extend at the upper edges 10 "of these walls 10 by return portions 14, which cover said upper edges 10" and extend partially over the continuous wall structure carrier 11 and vapor barrier 13 carried by this structure 11 (for example formed of elements of the type steel tray). These portions 14 are assembled continuously directly by welding, gluing or cold adhesion, or indirectly via a waterproofing membrane (where appropriate with formation of a tightness statement) to the vapor barrier screen. 13, this depending on the nature of the latter, said portions 14 extending at least until being located under or layer (s) 12 'forming the sealing surface component of the complex 12, 12'.

La figure 6 illustre une troisième variante constructive de l'invention, moins performante au niveau thermique, dans laquelle la paroi latérale 10 s'étend verticalement au-delà du toit 10' et forme un bord relevé périphérique (acrotère) recouvert par la couvertine 20. Dans ce cas également, les bandes d'écran 7' se prolongent par des portions 14 formant retours qui recouvrent le bord supérieur 10" de la paroi 10 concernée.The figure 6 illustrates a third constructive variant of the invention, less efficient at the thermal level, wherein the side wall 10 extends vertically beyond the roof 10 'and forms a peripheral raised edge (acroterium) covered by the cover 20. In this also, the screen strips 7 'are extended by return portions 14 which cover the upper edge 10 "of the wall 10 concerned.

Enfin, l'invention concerne également un procédé de construction d'un bâtiment tel que décrit précédemment et représenté par parties sur les figures des dessins annexés.Finally, the invention also relates to a method of constructing a building as described above and shown in parts in the figures of the accompanying drawings.

Ce procédé consiste essentiellement à mettre en place la dalle 18, le soubassement ou analogue et l'ossature primaire 2, puis à réaliser une enveloppe de bâtiment provisoire étanche à l'eau, sensiblement étanche à l'air et perméable à la vapeur d'eau, formée d'un toit 10' pourvu d'un complexe d'isolation et d'étanchéification 12, 12' et de parois latérales 10 provisoires comprenant chacune une structure de paroi continue 3', une première couche d'isolation 4 externe ou interne (par rapport à 3') et un écran continu 7, à réaliser ensuite, de manière indépendante et éventuellement à des périodes distinctes, des opérations d'équipement, d'aménagement et de parement des faces internes, d'une part, et des faces externes, d'autre part, desdites parois latérales 10 et, le cas échéant, du toit 10' et, enfin, à effectuer les travaux de finition éventuellement souhaités ou nécessaires.This method consists essentially in setting up the slab 18, the bedrock or the like and the primary frame 2, then in making a temporary building envelope waterproof, substantially airtight and vapor permeable. water, formed of a roof 10 'provided with an insulation and sealing complex 12, 12' and temporary side walls each comprising a continuous wall structure 3 ', a first external insulation layer 4 or internal (with respect to 3 ') and a continuous screen 7, to be carried out independently, and possibly at different periods, operations of equipment, layout and facing of the internal faces, on the one hand, and external faces, on the other hand, said side walls 10 and, where appropriate, the roof 10 'and, finally, to carry out any finishing work desired or necessary.

Après la phase de réalisation de l'enveloppe de bâtiment provisoire, l'écran 7 constitue ainsi la couche externe enveloppante au niveau des différentes parois latérales 10 et est relié, de manière continue et avec réalisation de l'étanchéité à l'eau et à l'air, au toit 10' et à la dalle 18, au soubassement ou analogue, permettant ainsi d'aboutir à un bâtiment hors d'eau et étanche à l'air.After the construction phase of the temporary building envelope, the screen 7 thus constitutes the enveloping outer layer at the level of the various lateral walls 10 and is connected, in a continuous manner and with the achievement of watertightness and watertightness. air, roof 10 'and slab 18, the basement or the like, thus resulting in a building out of water and airtight.

Afin d'évaluer les performances de l'enveloppe du bâtiment en cours de construction et éventuellement de permettre de corriger, avant les travaux de finition, de possibles imperfections au niveau de l'étanchéité à l'air de l'enveloppe, le procédé consiste avantageusement à réaliser au moins un test d'étanchéité à l'air du bâtiment par mise en surpression du volume intérieur de ce dernier, au moins après achèvement de l'enveloppe provisoire étanche à l'eau, sensiblement étanche à l'air et perméable à la vapeur d'eau, à localiser les emplacements des éventuelles fuites et, le cas échéant, à réaliser les travaux nécessaires pour limiter, voire supprimer, lesdites fuites.In order to evaluate the performance of the building envelope under construction and possibly to correct, before the finishing work, possible imperfections in the airtightness of the envelope, the process consists of advantageously to carry out at least one test of airtightness of the building by putting overpressure of the internal volume of the latter, at least after completion of the temporary waterproof envelope, substantially airtight and permeable with the steam, to locate the locations of any leaks and, if necessary, to carry out the work necessary to limit or even eliminate said leaks.

Compte tenu de la qualité de l'étanchéité à l'air de l'enveloppe du bâtiment selon l'invention, ces tests peuvent être réalisés avec un équipement à puissance limitée (porte soufflante), même dans le cas d'un bâtiment de volume important (par exemple supérieur à 1 000 m3).Given the quality of the airtightness of the building envelope according to the invention, these tests can be performed with a limited power equipment (fan door), even in the case of a building volume important (eg greater than 1000 m 3 ).

Grâce à l'invention, il est donc possible de proposer un bâtiment à ossature légère dont les performances thermiques sont notablement améliorées (les inventeurs ont relevé un gain de 50 à 75 % en termes de consommation d'énergie de chauffage).Thanks to the invention, it is therefore possible to provide a lightweight frame building whose thermal performance is significantly improved (the inventors have found a gain of 50 to 75% in terms of heating energy consumption).

En outre, il est également possible d'aboutir, en cours de réalisation du bâtiment, rapidement à une construction provisoire hors d'eau, isolée thermiquement et sensiblement étanche à l'air. Cette construction provisoire permet aux différents intervenants extérieurs et intérieurs d'effectuer les travaux qui leur sont attribués de manière indépendante, l'étanchéité à l'air du bâtiment étant du ressort d'un unique prestataire, même au niveau des interfaces entre les différents lots du chantier.In addition, it is also possible to achieve, during construction of the building, quickly to a temporary construction out of water, thermally insulated and substantially airtight. This temporary construction allows the various external and internal participants to carry out the work allocated to them independently, the air tightness of the building being the responsibility of a single provider, even at the level of the interfaces between the different batches. of the building site.

L'invention repose, par conséquent, sur le principe de base qui consiste à utiliser les caractéristiques d'un produit existant étanche à l'air et perméable à la vapeur d'eau pour permettre de faire l'étanchéité à l'air à l'extérieur d'un bâtiment (ce qui est contraire à la pratique usuelle). Cette particularité de réaliser l'étanchéité à l'air à l'extérieur avec une paroi perméable à la vapeur d'eau (pour éviter tout problème de point de rosée et de condensation dans la paroi) permet de s'affranchir de tous les points singuliers intérieurs difficiles à traiter (refend, dalle intermédiaire, percement divers...). De plus, la perméabilité à la vapeur d'eau permet aux différents composants de sécher en cas d'humidification accidentelle.The invention is therefore based on the basic principle of utilizing the characteristics of an existing airtight and water vapor permeable product to enable airtightness to be achieved at the same time. exterior of a building (which is contrary to usual practice). This peculiarity of achieving airtightness on the outside with a wall permeable to water vapor (to avoid any problem of dew point and condensation in the wall) makes it possible to get rid of all the singular interior points difficult to treat (slitting, intermediate slab, various drilling ...). In addition, the permeability to water vapor allows the various components to dry in case of accidental humidification.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des drivers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, in particular from the point of view of the constitution of the driver elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
