Abstract

The breaker has a variable thickness lower layer (3) e.g. polystyrene, made of non-flammable thermally insulated material. The layer supports an upper layer (4) made of non-combustible insulation material e.g. rock wool. The layer (4) is of greater width than that of the layer (3) to project from each edge (21) of the layer (3). The breaker is partly broken to create a reinforced concrete joint between wall tie (7) and floor (8). An independent claim is also included for a method for construction of buildings using thermal bridge breakers.

Description

La présente invention concerne les rupteurs de ponts thermiques et un procédé de construction de bâtiment comportant de tels rupteurs:
Les bâtiments sont habituellement prévus pour être isolés thermiquement par l'intérieur , mais on constate que l'isolation thermique n'est pas régulière, elle est soit interrompue, soit réduite au niveau du chaînage des planchers et des murs de refend créant des ponts thermiques qui nuisent fortement à la fonction isolante de la construction.
La présente invention a pour but de remédier à cet inconvénient en fournissant des éléments composites isolants appelés rupteurs de ponts thermiques capables d'assurer la continuité de l'isolation thermique au droit des planchers et des murs de refend tout en assurant la cohésion, la solidité, la résistance et la fonction coupe-feu du plancher.
L'invention a, en effet, pour objet un système de rupteurs de ponts thermiques au droit des planchers et des murs de refend capable de s'intercaler entre le chaînage et le plancher préfabriqué en béton armé ou précontraint et d'entrer en contact, sans interruption, avec toutes les autres couches voisines de matériaux isolants des systèmes de construction à isolation thermique par l'intérieur.
Selon un mode de réalisation préféré, le rupteur de ponts thermiques est composé de deux couches de matériaux thermiquement isolant de nature différente, la première couche inférieure d'épaisseur variable, tel que du polystyrène ou équivalent, est support de la deuxième couche plus mince incombustible tel que de la laine de roche ou analogue. Les deux couches de matériaux thermiquement isolantes sont reliées entre elles, soit par fixations, soit par collage (19).
Chacun des éléments ainsi formé constitue une coupure thermique efficace en prolongeant les parois isolées par l'intérieur de la construction, tout en rendant impossible la propagation du feu par un véritable écran pare-feu.
L'invention s'étend également au procédé de construction formé à l'aide des rupteurs thermiques associés à un plancher préfabriqué à poutrelles et entrevous en béton armé ou précontraint. Des noyaux de liaisons mécaniques en béton armé sont prévues entre le plancher et le gros- u̇vre permettant d'une part, de transférer les charges et les surcharges du plancher sur les éléments porteurs de la construction et d'autre part, d'assurer la fonction diaphragme du plancher préfabriqué. La résistance, la stabilité et la cohésion de l'ouvrage s'en trouvent assurées.
La description, ci-dessous, d'un mode de réalisation donné à titre d'exemple non limitatif de l'invention et représenté aux dessins annexés fera d'ailleurs ressortir les avantages et caractéristiques de l'invention.
Sur les dessins, - la fig. 1 est une coupe verticale du rupteur thermique posé parallèlement aux poutrelles du plancher préfabriqué. - la fig.2 est une vue de face du rupteur thermique posé parallèlement aux poutrelles du plancher préfabriqué. - la fig.3 est une vue de côté du rupteur thermique posé parallèlement aux poutrelles du plancher préfabriqué. - la fig. 4 est une coupe verticale du rupteur thermique posé perpendiculairement aux poutrelles du plancher préfabriqué - la fig. 5 est une vue de face du rupteur thermique posé perpendiculairement aux poutrelles du plancher préfabriqué. - la fig. 6 est une vue de côté du rupteur thermique posé perpendiculairement aux poutrelles du plancher préfabriqué. - la fig.7 est une vue en plan du positionnement des rupteurs thermiques posés parallèlement et perpendiculairement aux poutrelles du plancher préfabriqué. - la fig. 8 est une vue de côté des rupteurs thermiques posés parallèlement aux poutrelles du plancher préfabriqué. - la fig. 9 est une vue de côté des rupteurs thermiques posés perpendiculairement aux poutrelles du plancher préfabriqué.
Comme le montre ces dessins, le rupteur thermique (1) placé parallèlement aux poutrelles (2) du plancher préfabriqué (8) est formé de deux couches de matériaux thermiquement isolant, une couche épaisse (3) tel que du polystyrène ou équivalent, qui forme l'organe support de la couche supérieure isolante (4) plus mince en matériau isolant incombustible, type laine de roche ou équivalent rendant impossible la propagation du feu. La couche de matériau isolant incombustible (4) du rupteur posé parallèlement aux poutrelles est partiellement interrompue (5) pour permettre la création de noyaux de liaison (6) en béton armé, après la pose de l'armature (9) et du bétonnage du plancher (10), entre le chaînage périphérique (7) et le plancher préfabriqué (8).
Le rupteur de pont thermique (1) placé parallèlement aux poutrelles comporte, dans la couche épaisse basse, plusieurs encoches (11) et (12) dont la fonction est de servir d'appui et de positionnement sur l'élément porteur (18) et sur la poutrelle (2) préfabriquée du plancher.
Comme le montre ces dessins, le rupteur de pont thermique (13) perpendiculaire aux poutrelles est partiellement interrompu.pour permettre de créer une liaison en béton armé (14) permettant aux poutrelles (2) du plancher préfabriqué de transférer les charges et les surcharges du plancher sur le système porteur (18) du plancher permettant d'assurer sa résistance .
Le rupteur de pont thermique (13) posé perpendiculairement aux poutrelles comporte sans sa couche épaisse basse plusieurs encoches (15) et (16) servant d'appui, de maintien, de positionnement sur l'élément porteur (18) d'une part, et d'autre part, sur les poutrelles (2) préfabriquées du plancher.
La couche de matériau isolant incombustible (4) située en partie supérieure des rupteurs (1) et (13) est d'une largeur supérieure à la partie isolante inférieure épaisse (3), de façon à déborder de chaque côté (21). La couche de matériau isolant incombustible se trouve ainsi ancrée dans le béton du chaînage d'une part et le béton du plancher d'autre part, rendant impossible la propagation du feu. Bien entendu, la couche de matériau thermiquement isolante d'épaisseur variable (3) située en partie basse des rupteurs est en matériau ininflammable.
Selon un mode de réalisation préféré, les rupteurs parallèles (1) aux poutrelles sont placés aux abouts des planchers, les uns à côté des autres FIG. 8, les rupteurs perpendiculaires (13) sont placés entre les poutrelles aux abouts du plancher FIG. 9.
Comme le montre ces dessins, les rupteurs thermiques (1) et (13) assurent la continuité (17) de l'isolation thermique par l'intérieur (20) de la construction éliminant les ponts thermiques entre le chaînage et le plancher, à l'exception des noyaux de liaison mécaniques en béton armé (6) et (14) nécessaires à la stabilité de l'ouvrage et à la fonction coupe-feu du plancher.The present invention relates to thermal bridge breakers and a building construction method comprising such breakers:
Buildings are usually designed to be thermally insulated from the inside, but it can be seen that the thermal insulation is not regular, it is either interrupted or reduced at the level of the chaining of the floors and the cross walls creating thermal bridges which strongly harm the insulating function of the construction.
The object of the present invention is to remedy this drawback by providing insulating composite elements called thermal bridge breakers capable of ensuring the continuity of the thermal insulation in line with the floors and the cross walls while ensuring cohesion and solidity. , resistance and fire resistance of the floor.
The subject of the invention is in fact a system of thermal bridge breakers in line with the floors and cross walls capable of interposing between the chaining and the prefabricated floor of reinforced or prestressed concrete and of coming into contact, without interruption, with all the other neighboring layers of insulating materials for interior thermal insulation building systems.
According to a preferred embodiment, the thermal bridge breaker is composed of two layers of thermally insulating material of different nature, the first lower layer of variable thickness, such as polystyrene or equivalent, supports the second thinner non-combustible layer such as rock wool or the like. The two layers of thermally insulating material are connected together, either by fasteners or by gluing (19).
Each of the elements thus formed constitutes an effective thermal break by extending the walls insulated by the interior of the construction, while making it impossible to propagate the fire by a real fire screen.
The invention also extends to the construction method formed using thermal breakers associated with a prefabricated floor with beams and interjoists of reinforced or prestressed concrete. Reinforced concrete mechanical connection cores are provided between the floor and the shell allowing, on the one hand, to transfer the loads and overloads from the floor to the load-bearing elements of the construction and, on the other hand, to ensure the diaphragm function of the prefabricated floor. The strength, stability and cohesion of the structure are ensured.
The description below of an embodiment given by way of nonlimiting example of the invention and shown in the accompanying drawings will moreover highlight the advantages and characteristics of the invention.
In the drawings, - fig. 1 is a vertical section of the thermal breaker placed parallel to the beams of the prefabricated floor. - Fig.2 is a front view of the thermal breaker placed parallel to the beams of the prefabricated floor. - Fig.3 is a side view of the thermal breaker placed parallel to the beams of the prefabricated floor. - fig. 4 is a vertical section of the thermal breaker placed perpendicular to the beams of the prefabricated floor - FIG. 5 is a front view of the thermal breaker placed perpendicular to the beams of the prefabricated floor. - fig. 6 is a side view of the thermal breaker placed perpendicular to the beams of the prefabricated floor. - Fig.7 is a plan view of the positioning of the thermal switches placed parallel and perpendicular to the beams of the prefabricated floor. - fig. 8 is a side view of the thermal breakers placed parallel to the beams of the prefabricated floor. - fig. 9 is a side view of the thermal breakers placed perpendicular to the beams of the prefabricated floor.
As shown in these drawings, the thermal breaker (1) placed parallel to the beams (2) of the prefabricated floor (8) is formed of two layers of thermally insulating material, a thick layer (3) such as polystyrene or equivalent, which forms the support member of the thinner upper insulating layer (4) made of non-combustible insulating material, such as rock wool or the like, making it impossible to spread fire. The layer of non-combustible insulating material (4) of the breaker placed parallel to the beams is partially interrupted (5) to allow the creation of connecting cores (6) in reinforced concrete, after the installation of the reinforcement (9) and the concreting of the floor (10), between the peripheral chaining (7) and the prefabricated floor (8).
The thermal bridge breaker (1) placed parallel to the beams comprises, in the low thick layer, several notches (11) and (12) whose function is to serve as support and positioning on the support element (18) and on the prefabricated beam (2) of the floor.
As shown in these drawings, the thermal bridge breaker (13) perpendicular to the joists is partially interrupted. To allow the creation of a reinforced concrete connection (14) allowing the joists (2) of the prefabricated floor to transfer the loads and overloads from the floor on the carrier system (18) of the floor to ensure its resistance.
The thermal bridge breaker (13) placed perpendicularly to the beams comprises, without its low thick layer, several notches (15) and (16) serving as support, holding, positioning on the support element (18) on the one hand, and on the other hand, on the prefabricated beams (2) of the floor.
The layer of noncombustible insulating material (4) located in the upper part of the breakers (1) and (13) is of a width greater than the thick lower insulating part (3), so as to overflow on each side (21). The layer of non-combustible insulating material is thus anchored in the concrete of the chaining on the one hand and the concrete of the floor on the other hand, making it impossible to spread the fire. Of course, the layer of thermally insulating material of variable thickness (3) located in the lower part of the breakers is made of non-flammable material.
According to a preferred embodiment, the breakers parallel (1) to the beams are placed at the ends of the floors, one next to the other FIGs. 8, the perpendicular breakers (13) are placed between the beams at the ends of the floor FIG. 9.
As shown in these drawings, the thermal breakers (1) and (13) ensure the continuity (17) of the thermal insulation by the interior (20) of the construction eliminating the thermal bridges between the chaining and the floor, at the 'except the reinforced concrete mechanical connection cores (6) and (14) necessary for the stability of the structure and the firebreak function of the floor.
