Abstract
Description
La présente invention concerne un dispositif pour isoler des maçonneries ou analogues de l'humidité, un milieu isolant liquide rejetant l'eau, de préférence un liquide isolant du type silicone étant alors placé dans da; trous borgnes. The present invention relates to a device for isolating masonry or the like from moisture, a liquid insulating medium rejecting water, preferably an insulating liquid of the silicone type then being placed in da; blind holes.
Pour former dans la maçonnerie de bâtiments sans couche d'arrêt d'humidité, une zone de rejet de l'eau, il est habituel de ménager dans la maçonnerie des trous dans lesquels un moyen d'isolation liquide rejetant l'eau est incorporé. Dans le brevet autrichien N" 253 178, on représente un dispositif à cet effet, les trous borgnes étant alors scellés vers ltextérieur par un tube de pression lors de l'incorporation du moyen d'isolation. Le moyen d'isolation est cependant absorbé avec une vitesse différente de trou à trou et de tuile à tuile ou bien par le mortier.Par conséquent, dans la plupart des cavités et des fissures présentes à l'intérieur de la maçonnerie,une partie du moyen d'isolation s'écoule sans efficacité, de sorte qu'il en résulte davantage d'utilisation de celui-ci qu'il n'en est nécessaire et qu on ne peut pas atteindre la répartition horizontale désirée du moyen d'isolation. To form in the masonry of buildings without a moisture barrier layer, a water rejection zone, it is usual to provide holes in the masonry in which a liquid insulation means rejecting water is incorporated. In the Austrian patent N "253 178, a device is represented for this purpose, the blind holes being then sealed towards the inside by a pressure tube during the incorporation of the means of insulation. The means of insulation is however absorbed with a different speed from hole to hole and from tile to tile or through the mortar. Consequently, in most of the cavities and cracks present inside the masonry, part of the insulation means flows ineffectively , so that it results in more use thereof than is necessary and that one cannot achieve the desired horizontal distribution of the insulation means.
On connait pour éviter cet inconvénient d'introduire dans les trous des tubes perforés dans lesquels est placé le moyen d'isolation. Le passage du moyen d'isolation peut alors être empêché ou complètement supprimé par le colmatage des orifices des trous. It is known to avoid this drawback of introducing perforated tubes into the holes in which the insulation means is placed. The passage of the insulation means can then be prevented or completely eliminated by the clogging of the holes of the holes.
On a donc déjà proposé de munir les trous perforés d'une enveloppe poreuse de caoutchouc mousse à pores ouverts ou de matière plastique du type mousse. It has therefore already been proposed to provide the perforated holes with a porous envelope of open-pored foam rubber or of plastic material of the foam type.
Le moyen d'isolation peut alors sortir par effet capillaire, même lors d'un colmatage éventuel des pores au voisinage de la surface de l'enveloppe, en une quantité suffisante et uniformément par toute la surface. L'écoulement superflu du moyen d'isolation dans les cavités ne peut pas cependant être empêché. The insulation means can then exit by capillary effect, even during a possible clogging of the pores in the vicinity of the surface of the envelope, in a sufficient quantity and uniformly over the entire surface. The superfluous flow of the insulation means into the cavities cannot however be prevented.
Selon la présente invention, on élimine cet inconvénient en introduisant dans les trous borgnes des boyaux de tissu imprégnes, de préférence en coton à fines mailles. According to the present invention, this drawback is eliminated by introducing into the blind holes casings of impregnated fabric, preferably cotton with fine mesh.
Grâce au tissu, la tension de surface se fait sentir et lutte contre le passage du moyen d'isolation. La pression du liquide d'isolation dans le boyau de tissu est choisie de manière qu'en raison de la tension de surface, aucun liquide ou presque aucun liquide ne sorte à des endroits, travers le tissu, où il y a des cavités dans la maçonnerie, ce qui veut dire qu'il n'y a aucun contact entre la maçonnerie et le tissu (effet de toile de tente). A l'inverse, lors du contact du tissu trempé de moyen d'isolation, avec la maçonnerie, la tension de surface est diminuée, de sorte qu'alors le moyen d'isolation sort ou bien est davantage transféré dans la maçonnerie. Thanks to the fabric, the surface tension is felt and fights against the passage of the insulation means. The pressure of the insulation liquid in the fabric hose is chosen so that due to the surface tension, no liquid or almost no liquid comes out at places, through the fabric, where there are cavities in the masonry, which means that there is no contact between the masonry and the fabric (tent canvas effect). Conversely, upon contact of the quenched fabric of insulation means with the masonry, the surface tension is reduced, so that the insulation means then leaves or is more transferred to the masonry.
Il est avantageux en outre que la face de contact efficace avec la maçonnerie soit importante à cause de la flexibilité du boyau de tissu. Par courbage sur l'extrémité interne du trou, le boyau de tissu peut être adapté d'une manière particulièrement simple à la longueur du trou borgne. La sortie de liquide est alors considérablement stoppée ou même entièrement stoppée à l'endroit de courbure. It is further advantageous that the effective contact face with the masonry is important because of the flexibility of the fabric hose. By bending over the internal end of the hole, the fabric hose can be adapted in a particularly simple way to the length of the blind hole. The liquid outlet is then considerably stopped or even entirely stopped at the point of curvature.
L'imprégnation du boyau de tissu a lieu de préférence par son trempage avec le milieu d'isolation et par séchage subséquent avant première utilisation du boyau de tissu. L'imprégnation consiste alors en milieu d'isolation séché, un liquide d'isolation du type silicone étant particulièrement utilisé. The impregnation of the fabric hose preferably takes place by soaking it with the insulating medium and by subsequent drying before first using the fabric hose. The impregnation then consists of a dried insulation medium, a silicone type insulation liquid being particularly used.
Finalement,lors de l'utilisation du dispositif selon la présente invention pour isoler des maçonneries, on peut procéder de telle manière qu'au début de l'isolation de la maçonnerie, on dilate briSvement au mcyen d'une surpression les mailles de tissu des boyaux pour déterminer l'écoulement du milieu d'isolation lors du processus d'isolation subséquent. On obtient de ce fait une sortie accélérée du moyen d'isolation en fonction de la nature de la maçonnerie. Finally, when using the device according to the present invention to isolate masonry, one can proceed in such a way that at the beginning of the insulation of the masonry, the mesh of fabrics of the hoses to determine the flow of insulation medium during the subsequent insulation process. This gives an accelerated exit from the insulation means depending on the nature of the masonry.
