Abstract

The insulation device for avoiding thermal rupture of a floor constituted by a concrete slab (4) on an assembly of beams (1) and floor blocks (3) consists of an insulating element (10) one side (11) of which is shaped to correspond with the beam section. The other side (12) is cut to a length so as to slightly overhang the length (X) separating the last beam from the wall (5) and to be encastered in the wall. An additional element (20) is placed on the insulating element and supported against the wall.

Description

tiges etant entoures par un carter inferieur ( 7) de la canne.rods being surrounded by a lower casing (7) of the rod.

La presente invention est relative a un dispositif destine a combattre les effete  The present invention relates to a device intended to combat the effects

de rupture thermique d'un plancher a l'autre.  thermal break from one floor to another.

I1 est connu de realiser des planchers ou separateurs d'etage en coulant une dalle de beton. De fa,con usuelle on dispose, comme elements porteurs, des poutrelles s en beton qui portent, entre elles, des entrevous qui peuvent etre en beton, en ceramique, en plastique ou en materiaux isolants, puis sur cet assemblage on coule  I1 is known to make floors or floor separators by pouring a concrete slab. As usual, we have, as load-bearing elements, concrete beams which carry, between them, interjoists which can be made of concrete, ceramic, plastic or insulating materials, then on this assembly we pour

une dalle de beton.a concrete slab.

Ces dalles de beton, d'un usage tres repandu, presentent ['inconvenient de former un pont thermique au niveau de la liaison entre le plancher ainsi realise et le mur. Pour supprimer ce pont thermique, on a deja propose des entrevous d'extremite qui vent constituees d'une partie horizontale, destinee a etre recouverte par le beton coule et une partie verticale s'etendant en hauteur jusqu'au niveau que  These concrete slabs, of very widespread use, have the drawback of forming a thermal bridge at the level of the connection between the floor thus produced and the wall. To remove this thermal bridge, we have already proposed end interjoists which consist of a horizontal part, intended to be covered by poured concrete and a vertical part extending in height up to the level that

doit atteindre la couche de beton qui sera coulee.  must reach the concrete layer which will be poured.

Ce produit donne d'excellents resultats, mais presente ['inconvenient d'etre de dimensions fixes aussi bien en largeur, quten hauteur et il en resulte qu'on ne peut pas  This product gives excellent results, but has the disadvantage of being of fixed dimensions as well in width, as in height and it results from it that one cannot

tonjours ['adapter aux dimensions du plancher que l'on coule.  always adapt to the dimensions of the floor being poured.

La presente invention a pour objet de supprimer cet inconvenient et concerne un element de raccord, en un materiau isolant, dont un cate a une forme analogue a un entrevous usuel de fa,con a pouvoir prendre appui sur la derriere poutrelle et dont l'autre cOte est. sur place, coupe a la largeur desiree de fa,con a faire la jonction entre  The object of the present invention is to eliminate this drawback and relates to a connecting element, made of an insulating material, one side of which has a shape analogous to that of a conventional interjoist, so that it can rest on the rear beam and the other East Coast. on site, cut to the desired width in a way, suitable for joining

deux etages.two floors.

De preference, cet element est complete par un insert additionnel dont ltepaisseur est determinee en fonction de l'epaisseur de la dalle en beton qui doit etre  Preferably, this element is completed by an additional insert whose thickness is determined according to the thickness of the concrete slab which must be

coulee.coulee.

A titre d'exemple et pour faciliter la comprehension de ['invention, on a represente aux dessins annexes: - Figure 1 une vue en coupe, perpendiculairement aux poutrelles d'un mode  By way of example and to facilitate understanding of the invention, the following drawings are shown: - Figure 1 a sectional view, perpendicular to the beams of a mode

de realisation du dispositif selon ['invention.  for making the device according to the invention.

- Figure 2 une vue en bout, d'un plancher muni des elements isolants selon ['invention. En se reportant a la figure 1 on volt que le plancher comporte, comme cela est connu, une pluralite de poutrelles 1 en beton, munies de fils de precontrainte 2, entre lesquelles vent mis en place des entrevous 3, qui peuvent etre en matiere ceramique,  - Figure 2 an end view of a floor provided with insulating elements according to the invention. Referring to FIG. 1, it can be seen that the floor comprises, as is known, a plurality of concrete beams 1, provided with prestressing wires 2, between which the wind is placed in between 3, which can be made of ceramic material. ,

en beton ou autres matieres.in concrete or other materials.

Sur cet assemblage on vient couler une dalle en beton 4.  On this assembly we pour a concrete slab 4.

Le probleme a resoudre se situe au niveau de la jonction entre la dalle 4 et le mur S. 0 Ledit mur 5 comporte, en general, des materiaux isolants et si l'on coule la dalle 4 jusqu'au mur 5, la dalle 4 va provoquer une rupture thermique dans ['isolation  The problem to be solved is at the junction between the slab 4 and the wall S. 0 Said wall 5 comprises, in general, insulating materials and if we pour the slab 4 to the wall 5, the slab 4 will cause thermal break in insulation

du mur.from the wall.

Pour eviter cette rupture, il est connu de disposer entre la derriere poutrelle 1 et le mur 5 un element isotherme; mais les dispositifs connus presentent ['inconvenient d'avoir des dimensions fixes, de sorte qu'il faut que le matre d'ccuvre calcule avec exactitude l'ecartement des poutrelles 1 de son plancher pour que la derriere poutrelle soit exactement a une distance X predeterminee du mur 5. Or, ltecartement entre les poutrelles 1 depend de la largeur des entrevous 3; de sorte qu'il est tres difficile, et meme parfois impossible, de respecter la cote X. Selon la presente invention, on realise un element de jonction en matiere isolante dont un des cotes 11 est conforme de fa,con a correspondre au profil de la poutrelle 1 afin de pouvoir y prendre appui, comme les entrevous 3, et dont l'autre cote 12 est coupe a la longueur voulue pour respecter la cote X plus une petite  To avoid this break, it is known to have an insulated element between the rear beam 1 and the wall 5; but the known devices have the drawback of having fixed dimensions, so that the supervisor must accurately calculate the spacing of the beams 1 from his floor so that the rear beam is exactly at a distance X predetermined wall 5. Now, the spacing between the beams 1 depends on the width of the interjoists 3; so that it is very difficult, and even sometimes impossible, to comply with dimension X. According to the present invention, a junction element made of insulating material is produced, one of the dimensions 11 of which conforms so that it corresponds to the profile of the beam 1 in order to be able to support it, like the interjoists 3, and the other dimension 12 of which is cut to the desired length to respect the dimension X plus a small

longueur Y permettant son encastrement dans l'epaisseur du mur 5.  length Y allowing it to be embedded in the thickness of the wall 5.

L'epaisseur Z de ltelement isolant 10 est egale ou legerement inferieure a  The thickness Z of the insulating element 10 is equal to or slightly less than

ltepaisseur des entrevous 3.the thickness of the interjoists 3.

De preference pour completer la suppression du pont thermique, on place sur ['element isolant 10 et en appui contre le mur 5 un element complementaire d'isolation 20, la largeur L de cet element etant quelconque (mats inferieure a celle de ['element 10) et sa hauteur H etant determinee de fac,on a etre au meme niveau que la  Preferably to complete the removal of the thermal bridge, a complementary element of insulation 20 is placed on the insulating element 10 and pressing against the wall 5, the width L of this element being arbitrary (mast less than that of the element 10) and its height H being determined so, we are at the same level as the

surface superieure de la dalle 4.upper surface of the slab 4.
