Description
L'invention concerne la réalisation d'une rupture thermique entre unThe invention relates to the realization of a thermal break between a
plancher (ou un refend) et un mur contigu. floor (or a slit) and an adjoining wall.
La publication FR 2 837 227 concerne un plancher constitué par une dalle coulée sur un support constitué d'entrevous portés par des poutrelles, avec un intervalle entre le plancher et un mur parallèle aux poutrelles. Un élément isolant est placé en appui sur la dernière poutrelle par une extrémité et encastré dans le mur par une extrémité opposée, et il est complété par un second élément isolant porté par le premier élément isolant dans l'intervalle entre l'extrémité de la dalle et le mur. Dans une telle conception, l'isolant est essentiellement situé à l'extérieur du mur et est porté en partie par le mur et en partie par la structure de plancher. The publication FR 2 837 227 relates to a floor consisting of a slab cast on a support consisting of interjoists carried by beams, with an interval between the floor and a wall parallel to the beams. An insulating element is placed in abutment on the last beam by one end and embedded in the wall by an opposite end, and it is completed by a second insulating element carried by the first insulating element in the gap between the end of the slab. and the wall. In such a design, the insulation is essentially located outside the wall and is carried partly by the wall and partly by the floor structure.
La publication WO 01/86082 qui concerne un plancher en béton porté par des poutrelles ancrées dans un mur, préconise d'utiliser des poutrelles de faible conductivité thermique, d'arrêter le béton du plancher avant le mur et de loger un isolant porté par les poutrelles dans l'intervalle ainsi constitué. The publication WO 01/86082 relates to a concrete floor carried by beams anchored in a wall, recommends using beams of low thermal conductivity, to stop the concrete floor before the wall and to house an insulator carried by the beams in the interval thus formed.
Ces solutions préconisées dans ces publications ne s'appliquent qu'à des planchers reposant sur des poutrelles indépendantes du mur ou ancrées dans le mur et impliquent que l'isolant soit intégralement ou pour l'essentiel situé à l'extérieur du mur. These solutions recommended in these publications apply only to floors resting on beams independent of the wall or anchored in the wall and imply that the insulation is wholly or mainly located outside the wall.
La présente invention concerne le cas d'une rupture thermique réalisée par un isolant intégralement ou pour l'essentiel situé dans le mur et applicable à tout type de plancher, y compris aux planchers dépourvus de poutrelles. The present invention relates to the case of a thermal break made by an insulator integrally or substantially located in the wall and applicable to any type of floor, including floors without joists.
Elle s'applique avantageusement au cas d'un plancher, porté par un mur, réalisé par coulage et durcissement d'un béton, et à un refend contigu au mur. It applies advantageously to the case of a floor, carried by a wall, made by pouring and hardening of a concrete, and a slit contiguous to the wall.
La publication FR 2 832 745 préconise de noyer dans l'épaisseur d'un mur réalisé par coulage d'un béton un insert isolant conçu et dimensionné pour se caler sur les deux parois entre lesquelles sera coulé le béton du mur. The publication FR 2 832 745 recommends drowning in the thickness of a wall made by casting a concrete insulating insert designed and sized to wedge on the two walls between which will be poured concrete wall.
Dans cette conception, le matériau isolant est porté par le mur, indépendamment du plancher mais la solution est complexe à mettre en oeuvre et d'un résultat aléatoire, du fait qu'il est impossible de contrôler l'état de l'isolant après coulage du béton du mur et difficile de vérifier sa position. In this design, the insulating material is carried by the wall, independently of the floor but the solution is complex to implement and a random result, because it is impossible to control the state of the insulation after casting concrete wall and difficult to check its position.
La publication FR 2 861 767 préconise d'éviter les 15 problèmes de l'insertion de l'isolant dans le mur en intégrant l'isolant à la dalle. The publication FR 2 861 767 recommends avoiding the problems of inserting the insulation in the wall by integrating the insulation to the slab.
La présente invention propose de réaliser la rupture thermique entre un mur et un plancher ou un refend au moyen d'un élément isolant intégré au mur, cet élément étant placé dans une cavité ouverte formée dans le mur de façon à déboucher par son ouverture à l'extérieur du mur en direction du plancher ou du refend. The present invention proposes to achieve the thermal break between a wall and a floor or a slit by means of an insulating element integrated in the wall, this element being placed in an open cavity formed in the wall so as to open by its opening to the wall. outside the wall towards the floor or the slit.
Il est ainsi facile de contrôler l'état et la position de l'isolant après la construction du mur. It is thus easy to control the state and position of the insulation after the construction of the wall.
Le qualificatif intégré signifie que l'élément isolant est intégralement ou au moins en majeure partie contenu dans le mur et est porté seulement par le mur, indépendamment du plancher ou du refend. The built-in qualifier means that the insulating element is wholly or at least largely contained in the wall and is carried only by the wall, regardless of the floor or the wall.
De préférence, on délimite la cavité au moyen d'une boîte ouverte que l'on place dans le coffrage du mur avant le coulage du béton du mur en sorte que l'ouverture de la boîte affleure une face du mur au droit du futur plancher ou du futur refend. Preferably, the cavity is defined by means of an open box that is placed in the wall formwork before pouring the concrete wall so that the opening of the box is flush with one side of the wall to the right of the future floor or the future split.
Dans le cas fréquent de parois de coffrage métalliques, on préconise d'utiliser une boîte également métallique qui peut facilement être positionnée par un effet magnétique. In the frequent case of metal formwork walls, it is recommended to use a box also metal which can easily be positioned by a magnetic effect.
La boîte peut également servir de façon connue en soi à la mise en place d'armatures d'attente qui assureront la liaison mécanique du mur avec la dalle ou le refend et, dans ce cas, il est prévu que l'isolant n'occupe qu'une partie de la boîte. L'isolant est de préférence placé dans la boîte avant le coulage du mur, mais il peut aussi être rapporté dans la boîte après construction du mur. The box can also be used in a manner known per se to the establishment of waiting frames which will ensure the mechanical connection of the wall with the slab or the slit and, in this case, it is expected that the insulation does not occupy only part of the box. The insulation is preferably placed in the box before pouring the wall, but it can also be returned to the box after the wall has been built.
On décrira ci-après des exemples de réalisation conformes à l'invention, en référence aux figures du dessin 15 joint sur lesquelles: É la figure 1 est une coupe transversale et verticale schématique du mur comportant un isolant selon l'invention; É la figure 2 est une coupe transversale et verticale 20 schématique du mur de la figure 1 après coulage d'une dalle de plancher, et É la figure 3 est une coupe horizontale schématique d'un mur comportant un isolant selon l'invention et d'un refend. Examples of embodiments according to the invention will be described below, with reference to the figures of the attached drawing, in which: FIG. 1 is a schematic transverse and vertical section of the wall comprising an insulator according to the invention; FIG. 2 is a schematic vertical cross-section of the wall of FIG. 1 after casting a floor slab, and FIG. 3 is a schematic horizontal section of a wall comprising an insulator according to the invention and FIG. a splinter.
Le mur représenté pour l'exemple sur les figures 1 à 3 est un voile de béton (1), coulé en place ou préfabriqué. The wall shown for the example in Figures 1 to 3 is a concrete veil (1), cast in place or prefabricated.
Selon l'invention, le voile comporte une cavité (2) qui débouche par une ouverture (2a) sur la face interne (la) du mur et qui contient un isolant (3) qui, dans cet exemple, affleure la face (la) du mur. De fait, l'isolant est placé dans une boîte (4) qui a été incorporée au mur, comme un insert, lors du coulage du béton du mur. According to the invention, the web has a cavity (2) which opens through an opening (2a) on the inner face (la) of the wall and which contains an insulator (3) which, in this example, is flush with the face (la) from the wall. In fact, the insulation is placed in a box (4) which has been incorporated into the wall, as an insert, during the pouring of concrete wall.
En dessus ou en dessous de l'isolant sont prévus dans le mur des armatures en acier (5) qui serviront à assurer la liaison mécanique du mur et de la dalle de plancher (6). Above or below the insulation are provided in the wall steel reinforcements (5) which will serve to ensure the mechanical connection of the wall and the floor slab (6).
Une boîte (7) ouverte sur la face interne (la) du mur, est avantageusement prévue, de façon connue en soi, pour loger les aciers (5) en position dépliée dans la boîte. Ces aciers seront dépliés au moment de l'exécution de la dalle. A box (7) open on the inner face (la) of the wall, is advantageously provided, in a manner known per se, for housing the steels (5) in the unfolded position in the box. These steels will be unfolded at the time of execution of the slab.
La boite (4) de l'isolant et la boite (7) des aciers en attente peuvent être constituées par deux zones ou deux compartiments d'une seule et même boite. The box (4) of the insulation and the box (7) of steel standby can be constituted by two zones or two compartments of one and the same box.
Dans le cas représenté, l'isolant (3) ne recouvre qu'une partie (a) de la tranche (c) du plancher (6) et déborde avantageusement cette tranche en partie supérieure. L'isolant pourrait aussi déborder en partie inférieure et/ou latéralement. In the case shown, the insulator (3) covers only part (a) of the wafer (c) of the floor (6) and advantageously overflows this slice in the upper part. The insulation could also overflow in the lower part and / or laterally.
De préférence, l'isolant couvre au moins 40% de la tranche de plancher (ou du refend). Preferably, the insulation covers at least 40% of the floor slice (or slit).
On notera que l'invention permet facilement de contrôler la position et la qualité de l'isolant avant le coulage de la dalle(ou du refend). Note that the invention makes it easy to control the position and quality of the insulation before pouring the slab (or the slit).
L'isolation peut être complétée, de façon connue en soi, par des parois de doublage (8) Dans le cas représenté, la dalle est encastrée partiellement (b) dans la boîte où se trouvent les aciers en attente. The insulation can be supplemented, in a manner known per se, by lining walls (8). In the case shown, the slab is partially embedded (b) in the box where the waiting steels are located.
