Description

La présente invention est relative à une sous-couche adaptée à la pose directe de carreaux ou carrelages sur une dalle de support, notamment en béton précontraint.The present invention relates to a sub-layer suitable for the direct laying of tiles on a support slab, in particular in prestressed concrete.

Lors de la construction de locaux, en particulier à usage d'habitation ou autres, il est fréquent d'équiper les rez-de-chaussée des bâtiments sur tout ou partie de leur surface avec du carrelage.When building premises, in particular for residential or other use, it is common to equip the ground floors of buildings on all or part of their surface with tiling.

Or, l'expérience montre que, sans précaution particulière, notamment si le retrait du béton après coulée de la dalle formant support, n'est pas complètement achevé, des désordres apparaissent. Ils consistent en un décollement ou une fissuration du carrelage.However, experience shows that, without any particular precaution, in particular if the removal of the concrete after pouring of the support slab, is not completely completed, disorders appear. They consist of detachment or cracking of the tiles.

Il est fréquent que, fixé à nouveau, le carrelage se désolidarise une nouvelle fois de son support apportant ainsi la preuve qu'il se passe à l'interface carrelage dalle des phénomènes physiques que le mortier de carrelage ne peut absorber. Même si la dalle est recouverte d'une chape de mortier d'épaisseur notable dans laquelle sont scellés les carreaux, on démontre par un modèle mathématique que le retrait du béton se traduit à l'interface entre la chape et le carrelage par une contrainte de cisaillement.It is frequent that, fixed again, the tiling is detached once again from its support thus bringing the proof that it occurs at the tiling interface slab of the physical phenomena that the tiling mortar cannot absorb. Even if the slab is covered with a thick mortar screed in which the tiles are sealed, it is demonstrated by a mathematical model that the shrinkage of the concrete results in the interface between the screed and the tiling by a stress of shear.

Cet effet préjudiciable est moins sensible lorsque les carreaux sont scellés dans une chape de mortier, mais la construction ne permet pas toujours de disposer au-dessus de la dalle d'une épaisseur libre acceptable.This detrimental effect is less noticeable when the tiles are sealed in a mortar screed, but the construction does not allow always have an acceptable free thickness above the slab.

L'effet préjudiciable est plus perceptible lorsque les carreaux ne sont plus scellés mais simplement collés notamment au moyen d'une couche de collage, en mortier colle disposée au-dessus de la dalle de béton, et cela d'autant plus que les carreaux sont de plus grande dimension.The detrimental effect is more noticeable when the tiles are no longer sealed but simply glued, in particular by means of a bonding layer, in adhesive mortar placed above the concrete slab, and all the more so since the tiles are larger.

La mise en place des carreaux par collage constituerait un procédé plus satisfaisant en raison de la rapidité de pose qu'il procure. Cependant, dans l'état actuel des règles de l'art (Cahiers de prescriptions techniques), la pose par collage est interdite sur de nombreux supports en béton ou béton précontraint, en particulier sur les dalles des maisons individuelles pour limiter des dommages quasi systématiques.The installation of the tiles by gluing would constitute a more satisfactory process because of the speed of laying that it provides. However, in the current state of the art (Cahiers de prescriptions techniques), laying by gluing is prohibited on many concrete or prestressed concrete substrates, in particular on the slabs of individual houses to limit almost systematic damage .

Or, lorsque la dimension des carreaux augmente, le scellement devient une pratique impossible, on ne peut, en effet, obtenir une assise parfaite du carreau de grande dimension par battage, sans risque de le briser, ce qui rend plus nécessaire encore la mise au point d'une technique de collage telle que la propose la présente invention.However, when the size of the tiles increases, sealing becomes an impossible practice, one cannot, in fact, obtain a perfect seating of the large tile by threshing, without the risk of breaking it, which makes it even more necessary to point of a bonding technique as proposed by the present invention.

La présente invention a pour objet une sous-couche pour la pose de carreaux ou d'un carrelage analogue, qui évite les invonvénients des solutions classiques, en permettant à la fois une pose facile de ce carrelage au moyen d'une substance de collage appropriée et un affaiblissement satisfaisant de la contrainte de cisaillement à l'interface entre la sous-couche et le carrelage.The subject of the present invention is a sub-layer for laying tiles or the like, which avoids the drawbacks of conventional solutions, by allowing both easy laying of this tile by means of an appropriate bonding substance. and a satisfactory weakening of the shear stress at the interface between the underlay and the tiling.

A cet effet, la sous-couche considérée, apte notamment à être disposée entre une dalle ou support en béton ou béton précontraint et une surface de revêtement formée par les carreaux jointifs et juxtaposés d'un carrelage, se caractérise en ce qu'elle est constituée par un matériau présentant un faible module d'élasticité, propre à constituer une zone de rupture ou d'affaiblissement pour la transmission des contraintes de la dalle vers le carrelage.To this end, the underlay considered, suitable in particular for being disposed between a concrete or prestressed concrete slab or support and a covering surface formed by the adjoining tiles and juxtaposed with a tiling, is characterized in that it is constituted by a material having a low modulus of elasticity, capable of constituting a zone of rupture or weakening for the transmission of the stresses from the slab to the tiling.

Dans un mode de réalisation particulier de l'invention, le matériau de la sous-couche est un matériau bitumineux sur lequel est disposé une couche mince d'un mortier de collage sur laquelle est directement posé le carrelage.In a particular embodiment of the invention, the material of the sub-layer is a bituminous material on which is placed a thin layer of a bonding mortar on which the tile is directly laid.

Avantageusement et dans ce premier mode de réalisation, le matériau bitumeux est un bitume convenablement fluxé et est revêtu sur sa face recevant la couche mince de mortier de collage d'une dispersion d'un granulé minéral, du type diorite, quartzite, silice ou analogue. De préférence également, la sous-couche de matériau bitumineux comporte dans sa face venant au contact de la dalle de béton une couche mince adhésive, facilitant sa liaison avec la surface de la dalle. De façon connue, la couche mince adhésive peut être revêtue d'un film de protection anti-adhérent en plastique, du type polyéthylène ou en papier siliconé, apte à être retiré de la couche d'adhésif avant application de la sous-couche de matériau bitumineux sur la dalle de béton. Le cas échéant, une couche intermédiaire peut être disposée entre la dalle et la sous-couche en matériau bitumineux.Advantageously and in this first embodiment, the bituminous material is a suitably fluxed bitumen and is coated on its face receiving the thin layer of bonding mortar with a dispersion of a mineral granule, of the diorite, quartzite, silica or similar type. . Preferably also, the sub-layer of bituminous material has in its face coming into contact with the concrete slab a thin adhesive layer, facilitating its connection with the surface of the slab. In a known manner, the thin adhesive layer can be coated with a non-stick protective protective film of plastic, of the polyethylene type or of silicone paper, capable of being removed from the adhesive layer before application of the material sublayer. bituminous on the concrete slab. If necessary, an intermediate layer can be placed between the slab and the sub-layer of bituminous material.

Dans un autre mode de réalisation, le matériau de la sous-couche est constitué par un mortier de collage incorporant dans une proportion convenable une émulsion d'une résine. De préférence, la résine de collage incorpore une proportion donnée de ciment, permettant l'absorption de l'eau excédentaire par réaction d'hydratation du ciment, en facilitant la pose du carrelage. Avantageusement, la résine utilisée est une résine formée d'un copolymère acrylovinylique.In another embodiment, the material of the sub-layer consists of a bonding mortar incorporating in an appropriate proportion an emulsion of a resin. Preferably, the bonding resin incorporates a given proportion of cement, allowing the absorption of excess water by hydration reaction of the cement, facilitating the laying of the tiles. Advantageously, the resin used is a resin formed from an acrylovinyl copolymer.

D'autres caractéristiques d'une sous-couche pour la pose de carreaux ou carrelages sur un dalle de béton précontraint apparaîtront encore à travers la description qui suit d'un exemple de réalisation donné à titre indicatif et non limitatif, en référence au dessin annexé sur lequel :

  • La Figure 1 est une vue en coupe et en perspective partielle d'une dalle de béton recouverte d'une surface en carrelage, celui-ci étant mis en place selon la pratique habituelle.
  • Les Figures 2 et 3 sont des vues également en coupe et en perspective partielle de sous-couches résilientes selon l'invention, correspondant à deux variantes de réalisation de cette dernière.
Other characteristics of an underlay for laying tiles on a prestressed concrete slab will become more apparent from the following description of an exemplary embodiment given by way of non-limiting example, with reference to the attached drawing. on which :
  • Figure 1 is a sectional view in partial perspective of a concrete slab covered with a tiled surface, the latter being put in place according to usual practice.
  • Figures 2 and 3 are views also in section and in partial perspective of resilient underlayers according to the invention, corresponding to two alternative embodiments of the latter.

Sur la Figure 1, la référence 1 désigne la partie supérieure d'une dalle en béton armé ou précontraint destinée notamment à constituer le plancher d'une maison d'habitation ou d'un local analogue, avec mise en place sur le dessus de la dalle d'un revêtement de carrelage 2 constitué, de façon en soi tout à fait classique, de carreaux jointifs et juxtaposés 3. Selon la pratique habituelle sur la pose d'un tel carrelage, on dépose sur la dalle 1 une couche épaisse 4 constituant une chape en mortier, dans laquelle les carreaux sont scellés en étant placés un par un à la surface de la chape, en les juxtaposant selon le dessin du carrelage à réaliser et les dimensions relatives de ces carreaux. De façon classique, les carreaux comportent dans leur face venant en contact avec le mortier de scellement une surface 5 non régulière et en particulier non plane, afin de faciliter le fluage du mortier dans les parties en creux ainsi présentées et solidariser parfaitement chaque carreau de la chape en assurant une parfaite horizontalité du revêtement.In Figure 1, the reference 1 designates the upper part of a reinforced or prestressed concrete slab intended in particular to constitute the floor of a dwelling house or a similar room, with placement on top of the slab of a covering of tiling 2 constituted, in itself quite classic, of contiguous and juxtaposed tiles 3. According to the usual practice on the laying of such a tiling, a thick layer 4 is deposited on the slab 1 a mortar screed, in which the tiles are sealed by being placed one by one on the surface of the screed, juxtaposing them according to the design of the tiling to be produced and the relative dimensions of these tiles. Conventionally, the tiles have in their face coming into contact with the sealing mortar a non-regular and in particular non-planar surface 5, in order to facilitate the creep of the mortar in the hollow parts thus presented and perfectly secure each tile of the screed ensuring perfect horizontality of the coating.

On constate cependant, pour les raisons déjà précisées, que si le retrait du béton de la dalle 1 n'est pas achevé de façon pratiquement complète, se produit à l'interface entre le carrelage 2 et la chape de mortier 4, des contraintes de cisaillement qui sont d'autant plus importantes que l'épaisseur de la chape est plus faible et surtout que les efforts de compression créés dans la dalle de béton consécutivement au retrait de ce dernier, sont plus grands. Or, selon les nécessités de la construction, il n'est pas toujours possible de réserver au-dessus de la dalle une hauteur de seuil suffisante pour la mise en place d'une chape épaisse. En outre, dans un souci de rentabilité de l'opération, il est préférable de procéder à la mise en place du carrelage en utilisant une technique de collage des carreaux, ceci d'autant plus que les dimensions de ces derniers sont elles-mêmes importantes. Dans ces conditions, les contraintes de cisaillement se produisent à l'interface 6 entre la chape et le carrelage 2 et deviennent telles qu'elles dépassent la résistance du mortier de collage utilisé dans une telle technique, en produisant inéluctablement des soulèvements ou fissures du carrelage qui se décolle du mortier, la libération des contraintes pouvant en outre s'accompagner d'un bruit d'explosion particulièrement gênant.However, it is noted, for the reasons already specified, that if the removal of the concrete from the slab 1 is not completed in a substantially complete manner, occurs at the interface between the tiling 2 and the mortar screed 4, constraints of shear which are all the more important as the thickness of the screed is lower and especially that the compressive forces created in the concrete slab following the withdrawal of the latter, are greater. However, depending on the requirements of the construction, it is not always possible to reserve above the slab a threshold height sufficient for the installation of a thick screed. In addition, for the sake of profitability of the operation, it is preferable to proceed with the installation of the tiling using a technique of gluing the tiles, this all the more so since the dimensions of the latter are themselves important. . Under these conditions, the shear stresses occur at the interface 6 between the screed and the tiling 2 and become such that they exceed the resistance of the bonding mortar used in such a technique, inevitably producing uplifts or cracks in the tiles which peel off from the mortar, the release of stresses being able to be accompanied by a particularly annoying explosion noise.

Conformément à l'invention, on réalise la mise en place du carrelage sur la dalle de béton en interposant entre eux une sous-couche résiliente 7, sur laquelle les carreaux 3 peuvent être directement collés selon la technique habituelle, et dont les Figures 2 et 3 illustrent respectivement deux variantes de réalisation.According to the invention, the tiling is carried out on the concrete slab by interposing between them a resilient underlay 7, on which the tiles 3 can be directly bonded according to the usual technique, and of which Figures 2 and 3 respectively illustrate two alternative embodiments.

Dans l'exemple illustré sur la Figure 2, la sous-couche résiliente 7 est constituée par un matériau bitumeux 8 et notamment un bitume fluxé approprié, présenté en plaques ou en rouleaux et qui peut être ainsi directement mis en place sur la dalle de béton 1. Avantageusement, la couche de bitume comporte dans sa surface dirigée vers le carrelage d'un revêtement 9 d'un granulé minéral, du genre diorite, quartzite, silice ou autre, permettant un bon accrochage sur la couche d'une faible épaisseur 10 d'un mortier de collage classique, sur laquelle les carreaux 3 du carrelage 2 sont ensuite disposés, conformément à la pratique habituelle. De préférence également, la sous-couche 7 comporte, sous la couche de bitume 8, un revêtement adhésif 11 qui facilite la mise en place sur la dalle de béton 1 et la solidarisation avec celle-ci de la couche déposée. De façon habituelle, le revêtement adhésif peut être protégé par un film plastique (non représenté) en polyéthylène ou en papier siliconé, ce film étant retiré avant la mise en place de la couche de bitume sur la dalle.In the example illustrated in FIG. 2, the resilient sub-layer 7 is constituted by a bituminous material 8 and in particular an appropriate fluxed bitumen, presented in plates or in rolls and which can thus be directly placed on the concrete slab 1. Advantageously, the bitumen layer comprises in its surface directed towards the tiling a coating 9 of a mineral granule, of the diorite, quartzite, silica or other type, allowing good adhesion to the layer of thin thickness 10 a conventional bonding mortar, on which the tiles 3 of the tile 2 are then arranged, in accordance with usual practice. Preferably also, the sub-layer 7 comprises, under the bitumen layer 8, an adhesive coating 11 which facilitates the placing on the concrete slab 1 and the joining with the latter of the deposited layer. Usually, the adhesive coating can be protected by a plastic film (not shown) made of polyethylene or silicone paper, this film being removed before the bitumen layer is placed on the slab.

Dans la variante illustrée sur la Figure 3, la sous-couche 7 est constituée par une épaisseur 12 d'un mortier de collage souple au sein de laquelle est dispersée une quantité appropriée d'une résine polymérisable, notamment du genre copolymère acrylovinylique, à laquelle est en outre ajoutée un certaine quantité de ciment, ce dernier contribuant d'une part à l'absorption de l'eau excédentaire dans la sous-couche par hydratation du ciment, et également à la fixation du carrelage. En effet, la pose de ce dernier à l'aide de la seule résine, poserait un problème de l'évacuation de l'eau d'émulsion qui resterait prisonnière entre le support et le carrelage et ne pourrait s'évacuer qu'au bout d'un temps très long, non compatible avec les contraintes de mise en oeuvre habituelles.In the variant illustrated in FIG. 3, the sub-layer 7 consists of a thickness 12 of a flexible bonding mortar within which is dispersed an appropriate quantity of a polymerizable resin, in particular of the acrylovinyl copolymer type, to which a certain amount of cement is also added, the latter contributing on the one hand to the absorption of excess water in the underlayment by hydration of the cement, and also to the fixing the tiles. Indeed, the installation of the latter using only resin, would pose a problem of the evacuation of the emulsion water which would remain trapped between the support and the tiling and could not be evacuated until the end. a very long time, not compatible with the usual implementation constraints.

On réalise ainsi une sous-couche résiliente permettant la pose facile et sûre d'un carrelage sur une dalle de béton, dont les caractéristiques permettent d'affaiblir de façon significative, voire d'éliminer les contraintes de cisaillement à l'interface entre ce carrelage et la sous-couche, et par suite de s'affranchir des inconvénients qui résultent d'un retrait non définitif du béton. Une telle sous-couche est d'un prix de revient réduit et présente une grande facilité d'emploi en même temps qu'elle permet de fixer le carrelage par le procédé de collage plus rapide et plus efficace, surtout lorsque la dimension des carreaux devient importante.A resilient underlay is thus produced allowing the easy and safe installation of a tile on a concrete slab, the characteristics of which make it possible to significantly weaken, or even eliminate the shear stresses at the interface between this tile. and the undercoat, and consequently to overcome the disadvantages which result from an indefinite withdrawal of the concrete. Such an undercoat has a reduced cost price and is very easy to use at the same time as it makes it possible to fix the tiles by the faster and more efficient bonding process, especially when the size of the tiles becomes important.

Bien entendu, il va de soi que l'invention ne se limite pas aux seuls exemples de réalisation donnés ci-dessus ; elle en embrasse au contraire toutes les variantes.Of course, it goes without saying that the invention is not limited to only the exemplary embodiments given above; on the contrary, it embraces all its variants.
