Description
La présente invention a trait aux produits isolants thermo-acoustiques fixés sur des supports présentant en général une surface régulière, par l'intermédiaire de plots de colle consistant en mortier adhésif. Le support est habituellement constitué de parpaings, béton, briques ou similaires.The present invention relates to fixed thermo-acoustic insulation products on supports generally having a regular surface, through glue dots consisting of adhesive mortar. Support is usually made of concrete blocks, concrete, bricks or the like.
A l'état fixé, l'isolant se trouve à une distance moyenne du support de l'ordre du centimètre, un tel espace étant lié à l'utilisation des plots de colle.In the fixed state, the insulation is at an average distance from the support of the order of the centimeter, such a space being linked to the use of the pads of glue.
L'isolant dont il s'agit ici est relativement rigide, consistant par exemple en laine de verre d'une densité de 10 à 80 kg/m3. Une laine de verre est susceptible de procurer une isolation thermique performante, une très bonne tenue mécanique, une isolation acoustique excellente, et elle est ininflammable ; son emploi peut donc notamment être recommandé pour doubler les murs séparant deux logements, les cages d'escalier et d'ascenseur ainsi que les murs de façade.The insulation in question here is relatively rigid, consisting for example of glass wool with a density of 10 to 80 kg / m 3 . Glass wool is capable of providing effective thermal insulation, very good mechanical strength, excellent acoustic insulation, and it is non-flammable; its use can therefore in particular be recommended to double the walls separating two dwellings, the stairwells and elevator, as well as the front walls.
La fixation d'isolant par plots de colle présente cependant quelques aspects problématiques.There are some aspects to fixing insulation with adhesive pads. issues.
Une bonne fixation suppose en général une promotion de l'adhésion des plots eux-mêmes à l'isolant, par préenduction de l'isolant au moyen d'une composition de mortier adhésif relativement fluide et susceptible de pénétrer superficiellement dans l'isolant. Cette préenduction, limitée éventuellement à l'emplacement des plots, est relativement consommatrice en mortier adhésif et longue à effectuer.A good fixation generally implies a promotion of the adhesion of studs themselves to the insulation, by pre-coating the insulation by means of a relatively fluid and susceptible to penetrating adhesive mortar composition superficially in the insulation. This pre-coating, possibly limited to the location of the studs, is relatively consuming in adhesive mortar and long to perform.
D'autre part les plots, régulièrement répartis à la surface de l'isolant, et de masses sensiblement identiques résultant d'un calibrage, sont à la fois nombreux et volumineux; les opérations consistant à calibrer, au moyen de moules, et répartir à la surface de l'isolant les plots, est longue elle aussi et la quantité de mortier adhésif employée importante. On the other hand, the studs, regularly distributed on the surface of the insulation, and substantially identical masses resulting from a calibration, are both numerous and bulky; the operations consisting in calibrating, using molds, and distributing the studs on the surface of the insulation is also long and the quantity of adhesive mortar used important.
Il existait donc un besoin pour une fixation de qualité au moins aussi bonne, telle qu'évaluée par des essais d'arrachement décrits en détails ci-dessous, et pouvant être obtenues par des opérations plus simples, moins longues et moins consommatrices de matières adhésives de valeur. Ce but est atteint par l'invention.There was therefore a need for a fixation of quality at least as good, as assessed by pullout tests described in detail below, and obtainable by simpler, shorter and less time consuming operations consumers of valuable adhesive materials. This goal is achieved by the invention.
A cet effet, l'invention a pour objet un produit d'isolation acoustique et/ou thermique comprenant un isolant de densité au moins égale à 10 kg/m3 et des plots de colle de masse et répartition à la surface de l'isolant appropriées. L'invention consiste plus particulièrement en ce qu'au moins un auxiliaire rigide de fixation de l'isolant sur un support comporte une première partie noyée dans un plot de colle et une seconde partie simultanément ancrée dans l'isolant. L'invention permet d'augmenter la résistance à l'arrachement de l'isolant tout en supprimant l'étape préalable de préenduction de mortier liquide, en diminuant le nombre des plots et la quantité de matière constituant chaque plot.To this end, the subject of the invention is an acoustic and / or thermal insulation product comprising an insulator with a density at least equal to 10 kg / m 3 and pads of mass adhesive and distribution on the surface of the insulator appropriate. The invention more particularly consists in that at least one rigid auxiliary for fixing the insulation to a support comprises a first part embedded in an adhesive pad and a second part simultaneously anchored in the insulation. The invention makes it possible to increase the tear resistance of the insulation while eliminating the prior step of pre-coating of liquid mortar, by reducing the number of pads and the amount of material constituting each pad.
De préférence, l'isolant est une laine minérale. Celle-ci, consistant en fibres minérales liées entre elles par une résine thermodurcissable telle que formophénolique, est parfaitement appropriée à la pénétration et l'ancrage mécanique de l'auxiliaire de fixation constitué, par exemple , d'une tige métallique d'extrémité pointue et de forme adaptée. Peuvent être citées, en tant que laines minérales, la laine de roche, et la laine de verre qui est préférée.Preferably, the insulator is mineral wool. This, consisting of fibers minerals bonded together by a thermosetting resin such as formophenolic, is perfectly suitable for penetration and anchoring mechanics of the fixing aid consisting, for example, of a metal rod pointed end and adapted shape. May be cited as wool mineral, rock wool, and glass wool which is preferred.
Selon un mode de réalisation, les plots de colle sont répartis sur une première face principale de l'isolant, dont la seconde face principale est solidaire d'une plaque rigide, telle qu'une plaque de plâtre de 5 à 25 mm, notamment 8 à 15 mm d'épaisseur. La plaque de plâtre, en général collée à l'isolant, est susceptible de constituer la paroi d'une pièce dans un bâtiment.According to one embodiment, the adhesive pads are distributed over a first main face of the insulation, of which the second main face is integral a rigid plate, such as a plasterboard of 5 to 25 mm, in particular 8 to 15 mm thick. The plasterboard, usually glued to the insulation, is likely to constitute the wall of a room in a building.
Conformément à d'autres caractéristiques :
- l'isolant est un feutre ou matelas d'épaisseur comprise entre 10 et 150 mm ;
- l'isolant a une densité au moins égale à 40 kg/m3, cette densité pouvant par ailleurs atteindre des valeurs de l'ordre de 80 kg/m3, mais n'excédant que rarement 100 kg/m3, dans des applications particulières.
- the insulation is a felt or mattress of thickness between 10 and 150 mm;
- the insulation has a density at least equal to 40 kg / m 3 , this density can moreover reach values of the order of 80 kg / m 3 , but rarely exceeding 100 kg / m 3 , in applications special.
L'invention a d'autre part pour objet l'auxiliaire rigide de fixation d'un isolant sur un support, décrit précédemment, et comprenant une première partie apte à faire saillie par rapport à la surface de l'isolant et à être noyée dans un plot de colle, et une seconde partie simultanément apte à être ancrée dans l'isolant. Il est intéressant que ladite première partie ait une forme telle qu'à l'état fixé de l'isolant, elle fasse saillie par rapport à la surface de l'isolant ; ainsi le plot de colle qui adhère au support de béton ou autre, comprend une partie de sa matière constitutive entre l'isolant et ladite première partie. Cette dernière est ainsi solidarisée au support béton par l'intermédiaire du plot, d'une part, et bien entendu, est solidaire de ladite seconde partie de l'auxiliaire rigide, notamment par le fait qu'elle est venue de matière avec celle-ci, d'autre part. Finalement, l'ancrage de la seconde partie de l'auxiliaire rigide de fixation dans l'isolant renforce la solidarisation de celui-ci au support.The invention also relates to the rigid auxiliary for fixing an insulator to a support, described above, and comprising a first part capable of making protrusion from the surface of the insulation and to be embedded in a glue pad, and a second part simultaneously capable of being anchored in the insulation. It is interesting that said first part has a shape such that in the fixed state of the insulation, it protrudes from the surface of the insulation; thus the glue pad which adheres to concrete or other support, includes some of its material constitutive between the insulator and said first part. The latter is thus secured to the concrete support via the stud, on the one hand, and well understood, is integral with said second part of the rigid auxiliary, in particular by the fact that it came together with it, on the other hand. Finally, anchoring the second part of the rigid fixing aid in the insulation strengthens the connection of the latter to the support.
Selon une caractéristique avantageuse de l'auxiliaire rigide de fixation, sa partie apte à être ancrée dans l'isolant comprend une fraction d'hélice ou plusieurs identiques. Ainsi l'auxiliaire de fixation est-il susceptible de pénétrer dans l'isolant par rotation selon un axe perpendiculaire à la surface de l'isolant ; ensuite, à l'inverse, une traction de l'isolant selon un tel axe ne permet pas d'en extraire l'auxiliaire de fixation.According to an advantageous characteristic of the rigid fixing aid, its part capable of being anchored in the insulation comprises a fraction of a helix or more identical. Thus the fixing aid is likely to penetrate into the insulation by rotation about an axis perpendicular to the surface of the insulation; then conversely, pulling the insulation along such an axis does not allow it to be extracted the fixing aid.
De préférence, l'auxiliaire rigide de fixation est métallique ou en matière plastique.Preferably, the rigid fixing aid is metallic or made of a material plastic.
Un autre objet de l'invention consiste en un procédé de fixation d'un produit d'isolation acoustique et/ou thermique sur un support au moyen de plots de colle, caractérisé en ce que l'on ancre au moins un auxiliaire rigide de fixation dans l'isolant, puis on le noie dans un plot de colle.Another object of the invention consists in a method of fixing a product acoustic and / or thermal insulation on a support by means of adhesive pads, characterized in that at least one rigid fixing aid is anchored in the insulation, then drown it in a glue pad.
L'intérêt essentiel de l'invention apparaít dans la description de l'exemple suivant, illustré par la figure unique en annexe, représentant en perspective un panneau de laine de verre dans lequel un auxiliaire rigide de fixation est en position intermédiaire d'ancrage.The essential interest of the invention appears in the description of the example following, illustrated by the single figure in the appendix, representing in perspective a glass wool panel in which a rigid fixing aid is in intermediate anchoring position.
En référence à cette figure, un auxiliaire rigide de fixation 1 est constitué
d'une tige métallique de 4 mm de diamètre et de forme complexe. Celle-ci
consiste en une première partie 2 sensiblement rectiligne de 12 cm de longueur
comprenant une saillie centrale 3 et prolongée à chacune de ses deux extrémités
par une fraction d'hélice constituant une seconde partie 4. Les deux fractions
d'hélice sont identiques et de même axe, passant par le centre, c'est-à-dire le
sommet de la saillie 3, chacune étant la transformée de l'autre par rotation de 180°
selon cet axe. Les extrémités, non apparentes et situées dans l'épaisseur de la
laine de verre 10, des deux fractions d'hélice sont pointues afin de faciliter la
pénétration dans celle-ci.With reference to this figure, a rigid fixing aid 1 is constituted
a
La position représentée est une position d'ancrage intermédiaire, dans
laquelle les fractions d'hélice 4 n'ont pas encore pénétré dans leur totalité dans la
laine de verre 10. A partir de cette position, une rotation de l'auxiliaire de fixation 1
selon l'axe des fractions d'hélice a pour effet de faire pénétrer progressivement la
totalité des fractions d'hélice 4 dans la laine de verre 10. Alors en position de
fixation de l'isolant 10 à un support, seule la première partie 2 de l'auxiliaire de
fixation 1 est située à l'extérieur de la laine de verre 10.The position shown is an intermediate anchoring position, in
which the
L'efficacité de cet auxiliaire de fixation 1 est évaluée de la manière suivante.The effectiveness of this fixing aid 1 is evaluated in the following manner.
On fixe sur un support en aggloméré de béton, au moyen de plots de mortier adhésif, des panneaux de laine de verre de 80 mm d'épaisseur et 50 kg/m3 de densité, sur lesquels est collée une plaque de plâtre de 10 mm d'épaisseur, produits composites commercialisés par la Société Saint-Gobain Isover France sous la dénomination commerciale Calibel.Glass wool panels 80 mm thick and 50 kg / m 3 density are fixed on a concrete agglomerate support, using adhesive mortar pads, onto which a 10 mm plasterboard is glued. thick, composite products marketed by the Saint-Gobain Isover France Company under the trade name Calibel.
On utilise un mortier adhésif commercialisé sous la dénomination M.A.P. par la société Placoplâtre, dont 25 kg sont mélangés à 13 à 13,5 litres d'eau. Préalablement, l'emplacement des plots sur la laine de verre a été préenduit au moyen du même mortier deux fois plus dilué.An adhesive mortar sold under the name M.A.P. is used. by the company Placoplâtre, of which 25 kg are mixed with 13 to 13.5 liters of water. Beforehand, the location of the studs on the glass wool was pre-coated at the using the same mortar twice as diluted.
Deux panneaux de 2 m de haut et 1,2 m de large sont fixés bord à bord sur le support. Les plots sont disposés régulièrement espacés à l'aide d'un gabarit : sur la hauteur de 2m sont réparties 5 rangées de plots espacées en leur centre de 400 mm, les deux rangées extrêmes étant distantes de 200 mm des bords, tandis que sur la largeur de 1,2 m sont réparties 4 rangées de plots espacées en leur centre de 300 mm, les deux rangées extrêmes étant distantes des bords de 150 mm. Les plots sont calibrés par le gabarit à 130 mm de diamètre et 15 mm d'épaisseur.Two panels, 2 m high and 1.2 m wide, are fixed edge to edge on the support. The studs are arranged regularly spaced using a template: on the height of 2m are distributed 5 rows of studs spaced in their center of 400 mm, the two extreme rows being 200 mm from the edges, while that over the width of 1.2 m are distributed 4 rows of studs spaced at their center of 300 mm, the two extreme rows being distant from the edges of 150 mm. The studs are calibrated by the template to 130 mm in diameter and 15 mm thick.
Après deux semaines de séchage, on perce 16 avant-trous de 8,5 mm, puis 12,5 mm de diamètre, au moyen d'un gabarit de 0,9m x 0,9m disposé pour moitié sur chacun des deux panneaux, puis on pose des chevilles commercialisées sous la marque Molly (6 mm x 37 mm x 15 mm), on fixe le gabarit que l'on soumet à une traction mesurée par un dynamomètre. L'arrachement est observé à plus de 97% dans les fibres, au voisinage des plots, pour une traction de 190 daN. After two weeks of drying, 16 pilot holes of 8.5 mm are drilled, then 12.5 mm in diameter, using a template of 0.9m x 0.9m arranged for half on each of the two panels, then ankles sold under Molly mark (6 mm x 37 mm x 15 mm), we fix the template which we submit to a traction measured by a dynamometer. The tearing is observed at more than 97% in the fibers, near the studs, for a traction of 190 daN.
On reproduit cet essai en employant un auxiliaire de fixation tel que décrit en relation avec la figure annexée, pour chaque plot de mortier adhésif, et en diminuant à la fois le nombre des plots et la masse de chacun ; de plus il n'est procédé à aucune préenduction de la laine de verre.This test is repeated using a fixing aid as described in relation to the appended figure, for each adhesive mortar pad, and in reducing both the number of studs and the mass of each; moreover it is not no pre-coating of glass wool.
Sur la hauteur de 2 m de chaque panneau sont ici réparties 4 rangées de plots espacées de 500 mm, les deux rangées extrêmes étant distantes de 250 mm des bords ; sur la largeur de 1,2 m sont réparties 3 rangées de plots espacées de 400 mm, les deux rangées extrêmes étant distantes de 200 mm des bords. L'épaisseur des plots est réduite à 100 mm. L'arrachement dans les mêmes conditions que ci-dessus n'est ici observé que pour une traction de 300 daN.On the height of 2 m of each panel are here distributed 4 rows of studs spaced 500 mm apart, the two extreme rows being 250 mm apart edges; over the width of 1.2 m are distributed 3 rows of studs spaced 400 mm, the two extreme rows being 200 mm from the edges. The thickness of the studs is reduced to 100 mm. Wrenching in the same conditions that above are observed here only for a traction of 300 daN.
L'emploi des auxiliaires de fixation de l'invention a donc permis d'augmenter la résistance à l'arrachement de l'ensemble constitué par les panneaux et leurs plaques de plâtre, en supprimant la préenduction, en diminuant le nombre des plots de 20 à 12 et leur masse d'un tiers.The use of the fixing aids of the invention therefore made it possible to increase the pull-out resistance of the assembly constituted by the panels and their plasterboard, eliminating the pre-coating, reducing the number of plots from 20 to 12 and their mass by a third.
