Definitions
- the invention relates to a substrate for sound insulation.
- a floating slab made from a glass veil. It is usual in the building industry and more particularly for the realization new housing or the repair of old housing to combat the transmission of noise from one accommodation to another.
- One of the nuisances main sound is caused by impact noise transmit through the floor.
- the invention thus relates more specifically to a substrate intended to improve sound insulation and more particularly to reduce the transmission of impact noise from a dwelling to another located below and therefore reducing the transmission of impact noise through the ground or floor.
- floating slabs or screeds for example made of cement
- main slab usually made of concrete armed which constitutes the separation between two superimposed housings.
- the floating slab or screed is made so as not to be in contact direct with the reinforced concrete slab nor with any partitions which are connected directly to said reinforced concrete slab. He is thus known to make the floating slab or screed by interposing between it and the reinforced concrete slab with acoustic insulating material.
- Insulating materials that can be used for this application are all the acoustic insulation materials usually used in the building industry; these may in particular be products of the bituminous type, mineral wool mattress type products, plastering materials, foam products, polystyrene, etc.
- the choice of these products may be limited by constraints imposed on them; first of all, the material used should be able to support heavy loads and therefore possibly be compressed while retaining its properties sound insulation. Furthermore, said acoustic properties of the material must keep over time, for a period minimum of ten years and advantageously for long periods more important.
- Materials more particularly well suited to this type of application are materials based on mineral fibers, or many bituminous materials, or even products combining these two materials. It appears that these materials allow obtain good sound insulation against impact noise and that this insulation is preserved almost constantly over time.
- the operators When making a floating slab or screed, the operators will therefore first install the insulating material.
- This installation consists of completely covering the concrete slab reinforced, as well as the lower part of the partitions bordering the area or room in which the floating slab or screed must be made.
- the the reinforced concrete slab is covered with the material chosen insulator in the form of a rectangular slab, especially in the case of a glass wool mattress; Recovery of the lower parts of the partitions is produced by strips of the same material that we call edge bands. These edge strips are generally obtained by cutting in plates similar to those covering the reinforced concrete slab; their width is defined by the thickness of the floating slab which will then be produced.
- This realization is therefore carried out with numerous cuts on the one hand to make the edge strips and also to adapt the dimensions of the plates to those of the part to be covered.
- the installation of all of these elements requires very rigorous important to guarantee a good connection between in particular the different plates between them and between the plates and the edge strips.
- the operator must then cover all of the material insulating with a waterproof material which protects the insulating material acoustics of humidity. Indeed, during the realization of the slab or floating screed, this usually being made of cement, the presence of waterproof material is essential to prevent any degradation of the insulating material due to the presence of moisture in the cement. It is also essential to protect the edge strips of the same risks, which increases the complexity of installing this waterproof material which like the insulating material must therefore cover the floor and the lower part of the partitions.
- the inventors have thus given themselves the mission of finding means of producing a floating slab or screed and more particularly the installation of an acoustic insulating coating simplified in view of the techniques usually used.
- This object was achieved according to the invention by carrying out a substrate for the acoustic insulation of a floating slab comprising a glass veil, the surface of one of the faces of said glass veil glass being associated with a waterproof plastic film.
- the substrate thus produced according to the invention has as first advantage of being able to simultaneously set up a acoustic insulating material and waterproof material.
- polyolefin (s) polyolefin (s), and preferably it is a film polyethylene, the film thickness preferably being at least about 150 microns.
- a film polyethylene the film thickness preferably being at least about 150 microns.
- such a film has the advantage of having interesting mechanical properties for the application.
- tests have shown that once the substrate thus produced and more particularly the aforementioned film has such resistance that it is possible for an operator to step on the substrate without damaging it and in particular without risk of damaging the waterproof film which has a resistance in particular to tearing completely satisfactory.
- this material to constitute the waterproof plastic film allows repair a cut or small tear with adhesive tape which adheres perfectly and in a sustainable way, guaranteeing perfect seal.
- This good resistance, in particular to tearing, waterproof material and the simplicity of repairing it in case guarantee the watertightness which is necessary during the subsequent realization of the floating screed.
- the plastic film is associated with the glass veil by bonding.
- An adhesive is preferably used which allows immediate adhesion; such bonding allows avoid any risk of slipping between the plastic film and the glass which could lead to flatness defects.
- Such glue is for example a "hot melt” adhesive such as Thermoresol A / F 460 adhesive marketed by the Bostik company.
- Other bonding systems such as for example double-sided adhesives, which also provide immediate adhesion can be used according to the invention.
- the glass fleece-plastic film assembly can advantageously be carried out in the factory immediately after the last stage of manufacture of the glass veil, according to techniques which are related by example in the manufacture of multilayer cardboard; the plastic film which can be rolled up a mat which conveys the veil coming out of the oven after baking the binder assembled with a glass veil after passing, for example on rollers glue coaters or by spraying glue on the glass veil.
- the glass veil is produced according to the usual so-called dry technique and it advantageously has a thickness between 5 and 10 mm and preferably close to 7 mm.
- the glass veil has a basis weight between 350 and 500 g / m 2 and preferably still close to 450 g / m 2 .
- the substrate according to the invention has a good resistance to crushing when making the screed floating but also over time. And the substrate according to the invention has sound insulation properties in view of impact noise completely satisfactory; laboratory tests according to the ISO 140 standard for measurement methodology have shown acoustic performance of the product according to the invention such as the value ⁇ Lw, defined according to ISO 717, that is 28 dB. Furthermore, such substrate according to the invention has a reduced thickness compared to to commonly used products with insulation comparable acoustics, which leads to material savings for the realization of the floating slab whose thickness must be proportional to that of the covering separating it from the concrete slab armed.
- the glass veil has at least one pre-cut along its length and on the face opposite to that associated with plastic film.
- Such precuts are made so as to allow subsequent folding of the substrate according to the lines formed by the precuts.
- These precuts can be made over the entire thickness of the glass veil or partially in its thickness; in the first case, the folding is carried out very simply since it is simply a question of folding the film, which retains the parts of the sail which were separated during the precut but which remain associated due to the presence of this film. In the second case, folding is more difficult since there remains a part of the thickness of the veil which is intact but on the other hand, the front substrate folding retains better integrity.
- Such folds will advantageously be carried out on the edges of the substrate, and the precuts are advantageously provided on each of the two edges, so that the folded part (s) come (s) to bear on a partition when placing the substrate to form an edge strip.
- the substrate thus described according to the invention will therefore allow the recovery of the floor and the lower part of the partitions.
- the substrate according to the invention allows in the case of edge strips, as mentioned above for covering of the floor, to simultaneously put in place the insulating material acoustics and the material that seals between this material insulation and floating slab.
- the substrate according to the invention comprises at least at least one adhesive strip partially attached to at least one length of plastic film, part of said adhesive strip remaining usable.
- the expression “remaining usable” means part of the adhesive area remains protected and can be fixed later to another substrate.
- the adhesive strip is glued to the substrate of not overflowing so that the non-adhering part is not not subject to possible tearing.
- This adhesive tape will allow the operator when putting in place of the substrate attach two substrates to each other while ensuring a perfect seal at the junction. Indeed, in depending on the dimensions of the floor to be covered, it can be necessary to use several substrates according to the invention, these having a limited width, and therefore to ensure the junction between these substrates.
- the presence of the adhesive tape thus allows according to the invention to make cover two substrates, the second coming between the first substrate and the adhesive strip partially fixed on said first substrate. It is thus possible to properly position the second substrate which comes into abutment on the bonding area and then we make adhere the adhesive strip to the second substrate so as to preserve this one in place.
- the adhesive tape then guarantees the watertightness of the junction zone between the two substrates.
- the substrate according to the invention may also include inscriptions allowing to position two substrates one relative to the other. It is indeed possible to provide inscriptions or patterns, especially on the plastic film which constitutes the upper face of the substrate when laying on the floor, for example to ensure the parallelism of two substrates.
- the substrate thus described according to the invention makes it possible to simplify the insulating material and material placement operations waterproof, on the one hand on a floor and on the other hand in overlap low parts of partitions, before the realization of a slab or screed floating.
- the substrate according to the invention also has other benefits ; the thinness of a glass veil and the flexibility of a plastic film allow a presentation of the substrate in the form of roller. This further simplifies when setting up the produced at the site because an unwinding operation is very simple. In addition, transport and handling of rollers are simpler than those of products in the form of plates or slabs.
- Figure 1 a side view of a substrate 1 according to the invention.
- This consists of a glass veil 2 on which is glued in full on its surface a polyethylene film 3.
- the glass veil has was carried out using the dry process technique.
- This technique consists of fiberizing by aerodynamic drawing a mixture of vitrifiable oxides mixed beforehand.
- the fibers are collected on a carpet conveyor in the form of nonwoven fibers to which a thermally crosslinkable binder and optionally longitudinal fibers of enhancement.
- the veil thus formed then passes through an oven to crosslink the binder.
- This film 3 which has a thickness of approximately 150 microns is in the form of a roll which is unwound above of the course of the glass veil 1 and is glued to the upper surface of this using the Bostik Thermoresol A / F 460 glue which is deposited on the spray film. It is thus possible to make the substrate 1 according to a continuous process which only lengthens the line of production of the glass veil.
- an adhesive strip 4 is partially glued to the polyethylene film 3 automatically immediately after assembly of glass fleece 2-polyethylene film 3. It appears more clearly in figure 2 how this adhesive strip 4 is positioned; it covers an edge of the substrate 1 along a large length by flush with its song but without going beyond. Such a realization allows in particular when the substrate is rolled or simply manipulated, not to risk tearing off this strip adhesive 4 accidentally, the latter remaining partially free.
- the free part of this adhesive strip 4 is protected by a film protective cover that the operator can remove by peeling when he needs to to use this part of the adhesive strip 4 to associate two substrates 1 to each other.
- these pre-cuts 5 were made over part of the thickness so that the glass veil retains integrity in itself. These pre-cuts 5 create lines which when laying substrates 1 on a floor will make it possible to fold, in particular to form the edge strips which cover the lower part of the partitions.
- Such precuts can also be made according to a transverse direction, and for example provided at intervals regular to allow folding in the other direction so that form the edge strips on the partitions perpendicular to the previous.
- Figure 3 is shown an assembly between two substrates 1 according to their length.
- the operator will partially superimpose the two substrates 1 so that the strip adhesive 4 initially fixed on one of the substrates covers the second substrate 1 and can adhere to its polyethylene film 3.
- This superposition causes a slight crushing of the two substrates which is preserved due to the holding by the adhesive tape 4.
- Figure 4 clearly shows that after assembling the two substrates 1, the strip adhesive 4 ensures a perfect seal at the level of the junction.
- rollers In order to provide a product that is simple to install and easy to transport, it is planned to provide the user with rollers whose weight advantageously does not exceed 25 kg, the substrate unrolled having a length of 30 meters or more and a width of 1.25 meters.
- Figure 4 shows an installation in exploded view of a realization of a floating slab.
- a substrate 1 according to the invention comprising in particular a glass veil 2 and a film polyethylene 3, which seals.
- the substrate 1 is folded so as to cover the lower part of said partitions along fold lines 8 which correspond to 5.
- These precuts are defined so that the strips of bank have a height greater than that of the floating slab which will be carried out.
- the floating slab or screed 9 can then be produced without risk of damaging the glass veil 2 which is protected from moisture by the polyethylene film 3.
- Above the floating slab 9, can then install a floor covering 10 and plinths 11.
- the substrates 1 according to the invention allow also to overlap the angles between two partitions particularly effective and simple to carry out. Indeed, it is possible at level of the angle that the operator eliminates a square of glass veil at using a sharp tool without cutting the polyethylene film; the square glass veil peels off very easily from the polyethylene film.
- a such a modification will make it possible to fold two parts of the substrate 1 to form two perpendicular edge strips without excess material in with regard to the glass veil and on the other hand retaining an excess of polyethylene film, which is not annoying and on the contrary guarantees sealing in this area where the usual techniques are often very delicate to implement to guarantee an equivalent result.
- the substrate thus described according to the invention therefore makes it possible to produce sound insulation effective over time in a simplified way and faster than the usual techniques.
Abstract
Description
L'invention concerne un substrat destiné à l'isolation acoustique d'une dalle flottante et réalisé à partir d'un voile de verre. Il est usuel dans l'industrie du bâtiment et plus particulièrement pour la réalisation de logements neufs ou la réfection de logements anciens de lutter contre la transmission des bruits d'un logement à un autre. Une des nuisances sonores principales est causée par les bruits d'impact qui se transmettent par le plancher.The invention relates to a substrate for sound insulation. a floating slab made from a glass veil. It is usual in the building industry and more particularly for the realization new housing or the repair of old housing to combat the transmission of noise from one accommodation to another. One of the nuisances main sound is caused by impact noise transmit through the floor.
L'invention concerne ainsi plus spécifiquement un substrat destiné à améliorer l'isolation acoustique et plus particulièrement à diminuer la transmission des bruits d'impact depuis un logement vers un autre situé en dessous et donc à diminuer la transmission des bruits d'impact au travers du sol ou plancher.The invention thus relates more specifically to a substrate intended to improve sound insulation and more particularly to reduce the transmission of impact noise from a dwelling to another located below and therefore reducing the transmission of impact noise through the ground or floor.
Il est usuel dans la construction ou la réfection de logements, notamment dans le but de réduire la transmission des bruits d'impact de réaliser des dalles ou chapes flottantes, par exemple réalisées en ciment, au-dessus de la dalle principale, généralement réalisée en béton armé qui constitue la séparation entre deux logements superposés. La dalle ou chape flottante est réalisée de manière à ne pas être en contact direct avec la dalle en béton armé ni avec les éventuelles cloisons qui sont reliées directement à ladite dalle en béton armé. Il est ainsi connu de réaliser la dalle ou chape flottante en intercalant entre celle-ci et la dalle en béton armé un matériau isolant acoustique.It is usual in the construction or the repair of housing, especially in order to reduce the transmission of impact noise to produce floating slabs or screeds, for example made of cement, above the main slab, usually made of concrete armed which constitutes the separation between two superimposed housings. The floating slab or screed is made so as not to be in contact direct with the reinforced concrete slab nor with any partitions which are connected directly to said reinforced concrete slab. He is thus known to make the floating slab or screed by interposing between it and the reinforced concrete slab with acoustic insulating material.
Les matériaux isolants pouvant être utilisés pour cette application sont tous les matériaux isolants acoustiques habituellement utilisés dans l'industrie du bâtiment ; il peut s'agir notamment de produits du type bitumineux, de produits de type matelas de laine minérale, de matériaux plâtreux, de produits mousseux, de polystyrène, etc....Insulating materials that can be used for this application are all the acoustic insulation materials usually used in the building industry; these may in particular be products of the bituminous type, mineral wool mattress type products, plastering materials, foam products, polystyrene, etc.
Toutefois, le choix de ces produits peut être limité par les contraintes qui s'imposent à eux ; tout d'abord, le matériau utilisé doit être capable de supporter des charges importantes et donc éventuellement être comprimé tout en conservant ses propriétés d'isolation acoustique. En outre, lesdites propriétés acoustiques du matériau doivent se conserver dans le temps, ceci pour une durée minimum de dix années et avantageusement pour des durées beaucoup plus importantes. Des matériaux plus particulièrement bien adaptés à ce type d'application sont les matériaux à base de fibres minérales, ou bien des matériaux bitumineux, ou bien encore des produits combinant ces deux matériaux. Il apparaít en effet que ces matériaux permettent d'obtenir une bonne isolation acoustique contre les bruits d'impact et que cette isolation se conserve de façon quasi constante dans le temps.However, the choice of these products may be limited by constraints imposed on them; first of all, the material used should be able to support heavy loads and therefore possibly be compressed while retaining its properties sound insulation. Furthermore, said acoustic properties of the material must keep over time, for a period minimum of ten years and advantageously for long periods more important. Materials more particularly well suited to this type of application are materials based on mineral fibers, or many bituminous materials, or even products combining these two materials. It appears that these materials allow obtain good sound insulation against impact noise and that this insulation is preserved almost constantly over time.
Lors de la réalisation d'une dalle ou chape flottante, le ou les opérateurs vont donc tout d'abord mettre en place le matériau isolant. Cette mise en place consiste à recouvrir intégralement la dalle de béton armé, ainsi que la partie basse des cloisons bordant la zone ou pièce dans laquelle la dalle ou chape flottante doit être réalisée. Le recouvrement de la dalle de béton armé est réalisé avec le matériau isolant choisi qui se présente sous forme de dalle rectangulaire, notamment dans le cas d'un matelas de laine de verre ; le recouvrement des parties basses des cloisons est réalisé par des bandes du même matériau que l'on qualifie de bandes rives. Ces bandes de rive sont généralement obtenues par découpe dans des plaques semblables à celles qui recouvrent la dalle de béton armé ; leur largeur est définie par l'épaisseur de la dalle flottante qui sera ensuite réalisée. Cette réalisation est donc effectuée avec de nombreuses découpes d'une part pour réaliser les bandes de rive et également pour adapter les dimensions des plaques à celles de la pièce à recouvrir. En outre, la mise en place de l'ensemble de ces éléments nécessite une rigueur très importante pour garantir une bonne jonction entre notamment les différentes plaques entre elles et entre les plaques et les bandes de rive.When making a floating slab or screed, the operators will therefore first install the insulating material. This installation consists of completely covering the concrete slab reinforced, as well as the lower part of the partitions bordering the area or room in which the floating slab or screed must be made. The the reinforced concrete slab is covered with the material chosen insulator in the form of a rectangular slab, especially in the case of a glass wool mattress; Recovery of the lower parts of the partitions is produced by strips of the same material that we call edge bands. These edge strips are generally obtained by cutting in plates similar to those covering the reinforced concrete slab; their width is defined by the thickness of the floating slab which will then be produced. This realization is therefore carried out with numerous cuts on the one hand to make the edge strips and also to adapt the dimensions of the plates to those of the part to be covered. In addition, the installation of all of these elements requires very rigorous important to guarantee a good connection between in particular the different plates between them and between the plates and the edge strips.
L'opérateur doit ensuite recouvrir l'intégralité du matériau isolant par un matériau étanche qui protège le matériau isolant acoustique de l'humidité. En effet, lors de la réalisation de la dalle ou chape flottante, celle-ci étant habituellement réalisée en ciment, la présence d'un matériau étanche est indispensable pour prévenir toute dégradation du matériau isolant due à la présence d'humidité dans le ciment. Il est également indispensable de protéger les bandes de rive des même risques, ce qui augmente la complexité de la pose de ce matériau étanche qui comme le matériau isolant doit donc recouvrir le plancher et la partie basse des cloisons.The operator must then cover all of the material insulating with a waterproof material which protects the insulating material acoustics of humidity. Indeed, during the realization of the slab or floating screed, this usually being made of cement, the presence of waterproof material is essential to prevent any degradation of the insulating material due to the presence of moisture in the cement. It is also essential to protect the edge strips of the same risks, which increases the complexity of installing this waterproof material which like the insulating material must therefore cover the floor and the lower part of the partitions.
La réalisation d'une dalle ou chape flottante est donc relativement compliquée du fait de la nécessité de réaliser un revêtement isolant acoustique auparavant et dont la pose est complexe.The realization of a floating slab or screed is therefore relatively complicated due to the need to carry out a acoustic insulation coating previously and whose installation is complex.
Les inventeurs se sont ainsi donné pour mission de trouver des moyens de réalisation d'une dalle ou chape flottante et plus particulièrement de la mise en place d'un revêtement isolant acoustique préalable simplifiés au vu des techniques habituellement utilisées.The inventors have thus given themselves the mission of finding means of producing a floating slab or screed and more particularly the installation of an acoustic insulating coating simplified in view of the techniques usually used.
Ce but a été atteint selon l'invention par la réalisation d'un substrat destiné à l'isolation acoustique d'une dalle flottante comportant un voile de verre, la surface d'une des faces dudit voile de verre étant associée à un film plastique étanche. This object was achieved according to the invention by carrying out a substrate for the acoustic insulation of a floating slab comprising a glass veil, the surface of one of the faces of said glass veil glass being associated with a waterproof plastic film.
Le substrat ainsi réalisé selon l'invention présente comme premier avantage de pouvoir mettre en place simultanément un matériau isolant acoustique et un matériau étanche.The substrate thus produced according to the invention has as first advantage of being able to simultaneously set up a acoustic insulating material and waterproof material.
Concernant ce dernier, il s'agit avantageusement, comme matière, de polyoléfine(s), et de préférence il s'agit d'un film polyéthylène, l'épaisseur du film étant de préférence d'au moins environ 150 microns. Outre ses propriétés d'étanchéité un tel film présente l'avantage de présenter des propriétés mécaniques intéressantes pour l'application. En effet, les essais ont montré qu'une fois mis en place le substrat ainsi réalisé et plus particulièrement le film précité présente une résistance telle, qu'il est possible à un opérateur de marcher sur le substrat sans le détériorer et notamment sans risque d'endommager le film étanche qui présente une résistance notamment au déchirement tout à fait satisfaisante. Par ailleurs, si toutefois un accident survenait le choix de ce matériau pour constituer le film plastique étanche permet de réparer une entaille ou une petite déchirure avec du ruban adhésif qui adhère parfaitement et de façon durable en garantissant une étanchéité parfaite. Cette bonne résistance, notamment au déchirement, du matériau étanche et la simplicité de le réparer en cas d'incident permettent de garantir l'étanchéité qui est nécessaire lors de la réalisation ultérieure de la chape flottante.Regarding the latter, it is advantageously, as material, polyolefin (s), and preferably it is a film polyethylene, the film thickness preferably being at least about 150 microns. In addition to its sealing properties, such a film has the advantage of having interesting mechanical properties for the application. In fact, tests have shown that once the substrate thus produced and more particularly the aforementioned film has such resistance that it is possible for an operator to step on the substrate without damaging it and in particular without risk of damaging the waterproof film which has a resistance in particular to tearing completely satisfactory. In addition, if, however, an accident occurs the choice of this material to constitute the waterproof plastic film allows repair a cut or small tear with adhesive tape which adheres perfectly and in a sustainable way, guaranteeing perfect seal. This good resistance, in particular to tearing, waterproof material and the simplicity of repairing it in case guarantee the watertightness which is necessary during the subsequent realization of the floating screed.
Avantageusement encore selon l'invention, le film plastique est associé au voile de verre par collage. On utilise de préférence une colle qui permet d'obtenir une adhésion immédiate ; un tel collage permet d'éviter tout risque de glissement entre le film plastique et le voile de verre qui pourrait conduire à des défauts de planéité. Une telle colle est par exemple une colle « hot melt » telle que la colle Thermoresol A/F 460 commercialisée par la société Bostik. D'autres systèmes de collage tels que par exemples des adhésifs double face, qui fournissent également une adhésion immédiate, peuvent être utilisés selon l'invention. Advantageously also according to the invention, the plastic film is associated with the glass veil by bonding. An adhesive is preferably used which allows immediate adhesion; such bonding allows avoid any risk of slipping between the plastic film and the glass which could lead to flatness defects. Such glue is for example a "hot melt" adhesive such as Thermoresol A / F 460 adhesive marketed by the Bostik company. Other bonding systems such as for example double-sided adhesives, which also provide immediate adhesion can be used according to the invention.
L'assemblage voile de verre-film plastique peut avantageusement être réalisé en usine immédiatement après la dernière étape de fabrication du voile de verre, selon des techniques qui s'apparentent par exemple à la fabrication de carton multicouche ; le film plastique qui peut se présenter sous forme de rouleau peut être déroulé au-dessus d'un tapis qui convoie le voile sortant du four après cuisson du liant et assemblé au voile de verre après passage par exemple sur des rouleaux enducteurs de colle ou par pulvérisation de la colle sur le voile de verre.The glass fleece-plastic film assembly can advantageously be carried out in the factory immediately after the last stage of manufacture of the glass veil, according to techniques which are related by example in the manufacture of multilayer cardboard; the plastic film which can be rolled up a mat which conveys the veil coming out of the oven after baking the binder assembled with a glass veil after passing, for example on rollers glue coaters or by spraying glue on the glass veil.
De préférence selon l'invention, le voile de verre est réalisé selon la technique usuelle dite par voie sèche et il possède avantageusement une épaisseur comprise entre 5 et 10 mm et de préférence voisine de 7 mm.Preferably according to the invention, the glass veil is produced according to the usual so-called dry technique and it advantageously has a thickness between 5 and 10 mm and preferably close to 7 mm.
Selon une réalisation préférée de l'invention, le voile de verre présente un grammage compris entre 350 et 500 g/m2 et de préférence encore voisin de 450 g/m2.According to a preferred embodiment of the invention, the glass veil has a basis weight between 350 and 500 g / m 2 and preferably still close to 450 g / m 2 .
Les essais ont montré qu'un tel voile de verre est tout à fait adapté à l'application des substrats destinés à l'isolation acoustique de dalles flottantes ; d'une part, le substrat selon l'invention présente une bonne résistance à l'écrasement lors de la réalisation de la chape flottante mais aussi dans le temps. Et le substrat selon l'invention présente des propriétés d'isolation acoustique au vu des bruits d'impact tout à fait satisfaisantes ; des tests réalisés en laboratoire selon la norme ISO 140 concernant la méthodologie de mesure ont montré une performance acoustique du produit selon l'invention telle que la valeur ΔLw, définie selon la norme ISO 717, soit de 28 dB. En outre, un tel substrat selon l'invention possède une épaisseur réduite par rapport aux produits habituellement utilisés présentant une isolation acoustique comparable, ce qui conduit à des économies de matière pour la réalisation de la dalle flottante dont l'épaisseur doit être proportionnelle à celle du revêtement la séparant de la dalle de béton armé. Tests have shown that such a glass veil is quite suitable for the application of substrates intended for sound insulation of floating slabs; on the one hand, the substrate according to the invention has a good resistance to crushing when making the screed floating but also over time. And the substrate according to the invention has sound insulation properties in view of impact noise completely satisfactory; laboratory tests according to the ISO 140 standard for measurement methodology have shown acoustic performance of the product according to the invention such as the value ΔLw, defined according to ISO 717, that is 28 dB. Furthermore, such substrate according to the invention has a reduced thickness compared to to commonly used products with insulation comparable acoustics, which leads to material savings for the realization of the floating slab whose thickness must be proportional to that of the covering separating it from the concrete slab armed.
Selon une réalisation avantageuse de l'invention le voile de verre comporte au moins une prédécoupe sur sa longueur et sur la face opposée à celle associée au film plastique. De telles prédécoupes sont réalisées de manière à permettre un pliage ultérieur du substrat selon les lignes formées par les prédécoupes. Ces prédécoupes peuvent être réalisées sur toute l'épaisseur du voile de verre ou partiellement dans son épaisseur ; dans le premier cas, le pliage est effectué très simplement puisqu'il s'agit simplement de plier le film, qui retient les parties de voile qui ont été séparées lors de la prédécoupe mais qui restent associées du fait de la présence de ce film. Dans le second cas, le pliage est effectué plus difficilement puisqu'il subsiste une partie de l'épaisseur du voile qui est intact mais par contre, le substrat avant pliage conserve une meilleure intégrité.According to an advantageous embodiment of the invention the glass veil has at least one pre-cut along its length and on the face opposite to that associated with plastic film. Such precuts are made so as to allow subsequent folding of the substrate according to the lines formed by the precuts. These precuts can be made over the entire thickness of the glass veil or partially in its thickness; in the first case, the folding is carried out very simply since it is simply a question of folding the film, which retains the parts of the sail which were separated during the precut but which remain associated due to the presence of this film. In the second case, folding is more difficult since there remains a part of the thickness of the veil which is intact but on the other hand, the front substrate folding retains better integrity.
De tels pliages vont avantageusement être réalisés sur les bords du substrat, et les prédécoupes sont avantageusement prévues sur chacun des deux bords, de façon à ce que la (ou les) partie(s) pliée(s) vienne(nt) en appui sur une cloison lors de mise en place du substrat pour former une bande de rive. Le substrat ainsi décrit selon l'invention va donc permettre de réaliser simultanément le recouvrement du plancher et de la partie basse des cloisons.Such folds will advantageously be carried out on the edges of the substrate, and the precuts are advantageously provided on each of the two edges, so that the folded part (s) come (s) to bear on a partition when placing the substrate to form an edge strip. The substrate thus described according to the invention will therefore allow the recovery of the floor and the lower part of the partitions.
Il est ainsi inutile de procéder à des découpes sur site pour réaliser les bandes de rive et d'autre part, la pose de ces différents éléments est grandement simplifiée par rapport aux techniques habituellement utilisées. En effet, la réalisation de ces prédécoupes peut être prévue en usine par exemple immédiatement après la réalisation du substrat, c'est-à-dire après l'assemblage du voile et du film plastique ; une telle réalisation en usine permet en outre avantageusement de définir très précisément la profondeur de la prédécoupe.It is therefore unnecessary to cut on site to realize the edge strips and on the other hand, the laying of these different elements is greatly simplified compared to techniques usually used. Indeed, the realization of these precuts can be planned in the factory for example immediately after completion of the substrate, that is to say after the assembly of the veil and the film plastic; such a factory production also allows advantageously define very precisely the depth of the pre-cut.
Par ailleurs, le substrat selon l'invention permet dans le cas des bandes de rive, comme il l'a été dit précédemment pour le recouvrement du plancher, de mettre en place simultanément le matériau isolant acoustique et le matériau qui assure l'étanchéité entre ce matériau isolant et la dalle flottante.Furthermore, the substrate according to the invention allows in the case of edge strips, as mentioned above for covering of the floor, to simultaneously put in place the insulating material acoustics and the material that seals between this material insulation and floating slab.
De façon avantageuse le substrat selon l'invention comporte au moins une bande adhésive fixée partiellement sur au moins une longueur du film plastique, une partie de ladite bande adhésive demeurant utilisable. L'expression " demeurant utilisable " signifie qu'une partie de la zone adhésive reste protégée et peut être fixée ultérieurement à un autre substrat.Advantageously, the substrate according to the invention comprises at least at least one adhesive strip partially attached to at least one length of plastic film, part of said adhesive strip remaining usable. The expression "remaining usable" means part of the adhesive area remains protected and can be fixed later to another substrate.
De préférence, la bande adhésive est collée sur le substrat de manière non débordante de sorte que la partie qui n'adhère pas ne soit pas sujette à un possible arrachement.Preferably, the adhesive strip is glued to the substrate of not overflowing so that the non-adhering part is not not subject to possible tearing.
Cette bande adhésive va permettre à l'opérateur lors de la mise en place du substrat de fixer deux substrats l'un à l'autre tout en assurant une étanchéité parfaite au niveau de la jonction. En effet, en fonction des dimensions du plancher qui doit être recouvert, il peut être nécessaire d'utiliser plusieurs substrats selon l'invention, ceux-ci ayant une largeur limitée, et donc d'assurer la jonction entre ces substrats. La présence de la bande adhésive permet ainsi selon l'invention de faire se recouvrir deux substrats, le second venant s'intercaler entre le premier substrat et la bande adhésive partiellement fixée sur ledit premier substrat. Il est ainsi possible de bien mettre en position le second substrat qui vient en butée sur la zone de collage et ensuite on fait adhérer la bande adhésive sur le second substrat de façon à conserver celui-ci en place. La bande adhésive garantit alors l'étanchéité de la zone de jonction entre les deux substrats.This adhesive tape will allow the operator when putting in place of the substrate attach two substrates to each other while ensuring a perfect seal at the junction. Indeed, in depending on the dimensions of the floor to be covered, it can be necessary to use several substrates according to the invention, these having a limited width, and therefore to ensure the junction between these substrates. The presence of the adhesive tape thus allows according to the invention to make cover two substrates, the second coming between the first substrate and the adhesive strip partially fixed on said first substrate. It is thus possible to properly position the second substrate which comes into abutment on the bonding area and then we make adhere the adhesive strip to the second substrate so as to preserve this one in place. The adhesive tape then guarantees the watertightness of the junction zone between the two substrates.
Le substrat selon l'invention peut encore comporter des inscriptions permettant de positionner deux substrats l'un par rapport à l'autre. Il est en effet possible de prévoir des inscriptions ou motifs, notamment sur le film plastique qui constitue la face supérieure du substrat lors de la pose sur le plancher, par exemple pour assurer le parallélisme de deux substrats.The substrate according to the invention may also include inscriptions allowing to position two substrates one relative to the other. It is indeed possible to provide inscriptions or patterns, especially on the plastic film which constitutes the upper face of the substrate when laying on the floor, for example to ensure the parallelism of two substrates.
Le substrat ainsi décrit selon l'invention permet de simplifier les opérations de mise en place d'un matériau isolant et d'un matériau étanche, d'une part sur un plancher et d'autre part en recouvrement des parties basses de cloisons, avant la réalisation d'une dalle ou chape flottante.The substrate thus described according to the invention makes it possible to simplify the insulating material and material placement operations waterproof, on the one hand on a floor and on the other hand in overlap low parts of partitions, before the realization of a slab or screed floating.
Le substrat selon l'invention présente en outre d'autres avantages ; la faible épaisseur d'un voile de verre et la flexibilité d'un film plastique autorisent une présentation du substrat sous forme de rouleau. Cela offre encore une simplification lors de la mise en place du produit sur le lieu du chantier car une opération de déroulement est très simple. En outre, le transport et les manipulations de rouleaux sont plus simples que ceux de produits qui se présentent sous forme de plaques ou dalles.The substrate according to the invention also has other benefits ; the thinness of a glass veil and the flexibility of a plastic film allow a presentation of the substrate in the form of roller. This further simplifies when setting up the produced at the site because an unwinding operation is very simple. In addition, transport and handling of rollers are simpler than those of products in the form of plates or slabs.
D'autres détails et caractéristiques avantageux de l'invention ressortiront ci-après de la description d'un exemple de réalisation d'un substrat en référence aux figures qui représentent :

Les différentes figures ne sont pas représentées à l'échelle de manière à simplifier la compréhension de l'invention.The different figures are not represented on the scale of so as to simplify the understanding of the invention.
Sur la figure 1 est représentée une vue de côté d'un substrat 1
selon l'invention. Celui-ci se compose d'un voile de verre 2 sur lequel est
collé en plein sur sa surface un film polyéthylène 3. Le voile de verre a
été réalisé selon la technique de voie sèche. Cette technique consiste à
fibrer par étirage aérodynamique un mélange d'oxydes vitrifiables
mélangés au préalable. Les fibres sont recueillies sur un tapis
convoyeur sous forme de fibres non tissées auxquelles on ajoute un
liant thermoréticulable et éventuellement des fibres longitudinales de
renforcement. Le voile ainsi constitué passe ensuite dans un four pour
faire réticuler le liant. A l'issue de cette fabrication continue, il est
possible, comme évoqué précédemment, d'associer au voile de verre 2 le
film polyéthylène 3. Ce film 3 qui présente une épaisseur d'environ 150
microns se présente sous forme d'un rouleau qui est dévidé au-dessus
du parcours du voile de verre 1 et est collé sur la surface supérieure de
celui-ci à l'aide de la colle Bostik Thermorésol A/F 460 qui est déposée
sur le film par pulvérisation. Il est ainsi possible de réaliser le substrat
1 selon un procédé en continu qui ne fait qu'allonger la ligne de
production du voile de verre.In Figure 1 is shown a side view of a
Si des inscriptions sur le film polyéthylène 3 sont nécessaires
lors de la mise en place, celles-ci peuvent également être réalisées
durant cette production.If inscriptions on
De même, une bande adhésive 4 est partiellement collée sur le
film polyéthylène 3 de manière automatique immédiatement après
l'assemblage voile de verre 2-film polyéthylène 3. Il apparaít plus
clairement sur la figure 2 la façon dont cette bande adhésive 4 est
positionnée ; elle couvre un bord du substrat 1 selon une grande
longueur en affleurant son chant mais sans aller au-delà. Une telle
réalisation permet notamment lorsque le substrat est mis en rouleau ou
simplement manipulé, de ne pas risquer d'arracher cette bande
adhésive 4 accidentellement, celle-ci demeurant partiellement libre. La
partie libre de cette bande adhésive 4 est protégée par un film
protecteur que l'opérateur pourra retirer par pelage lorsqu'il aura besoin
d'utiliser cette partie de la bande adhésive 4 pour associer deux
substrats 1 l'un à l'autre. Likewise, an
Durant le procédé de fabrication en continu du substrat 1, il est
encore possible de réaliser les prédécoupes 5. Sur la figure 1, ces
prédécoupes 5 ont été réalisées sur une partie de l'épaisseur de sorte
que le voile de verre conserve une intégrité en soi. Ces prédécoupes 5
créent des lignes qui lors de la pose des substrats 1 sur un plancher
vont permettre de réaliser des pliages, notamment pour former les
bandes de rive qui viennent couvrir la partie basse des cloisons.During the continuous manufacturing process of the
De telles prédécoupes peuvent également être réalisées selon une direction transversale, et par exemple prévues à des intervalles réguliers pour autoriser des pliages selon l'autre direction de façon à former les bandes de rive sur les cloisons perpendiculaires aux précédentes.Such precuts can also be made according to a transverse direction, and for example provided at intervals regular to allow folding in the other direction so that form the edge strips on the partitions perpendicular to the previous.
Sur la figure 3 est représenté un assemblage entre deux
substrats 1 selon leur longueur. Lors de la pose, l'opérateur va
partiellement superposer les deux substrats 1 de sorte que la bande
adhésive 4 fixée initialement sur l'un des substrats vienne recouvrir le
second substrat 1 et puisse adhérer sur son film polyéthylène 3. Cette
superposition provoque un léger écrasement des deux substrats qui est
conservé du fait du maintien par la bande adhésive 4. La figure 4
montre clairement qu'après assemblage des deux substrats 1, la bande
adhésive 4 permet de garantir une étanchéité parfaite au niveau de la
jonction.In Figure 3 is shown an assembly between two
De façon à fournir un produit simple à installer et facile à transporter, il est prévu de fournir à l'utilisateur des rouleaux dont le poids n'excède avantageusement pas 25 Kg, le substrat déroulé présentant une longueur de 30 mètres ou plus et une largeur de 1,25 mètres.In order to provide a product that is simple to install and easy to transport, it is planned to provide the user with rollers whose weight advantageously does not exceed 25 kg, the substrate unrolled having a length of 30 meters or more and a width of 1.25 meters.
La figure 4 montre une installation en vue éclatée d'une
réalisation d'une dalle flottante. Sur une dalle de béton armé 6, bornée
par des cloisons 7, un opérateur est venu déposer un substrat 1 selon
l'invention comportant notamment un voile de verre 2 et un film
polyéthylène 3, qui assure l'étanchéité. Au niveau des cloisons 7, le
substrat 1 est plié de façon à venir recouvrir la partie basse desdites
cloisons selon les lignes de pliages 8 qui correspondent aux
prédécoupes 5. Ces prédécoupes sont définies pour que les bandes de
rive présentent une hauteur supérieure à celle de la dalle flottante qui
sera réalisée. La dalle ou chape flottante 9 peut ensuite être réalisée
sans risque de détériorer le voile de verre 2 qui est protégé de l'humidité
par le film polyéthylène 3. Au-dessus de la dalle flottante 9, peuvent
ensuite être installés un revêtement de sol 10 et des plinthes 11.Figure 4 shows an installation in exploded view of a
realization of a floating slab. On a reinforced
Lors de l'installation, les substrats 1 selon l'invention permettent
également de réaliser un recouvrement des angles entre deux cloisons
particulièrement efficace et simple à réaliser. En effet, il est possible au
niveau de l'angle que l'opérateur élimine un carré de voile de verre à
l'aide d'un outil tranchant sans découper le film polyéthylène ; le carré
de voile de verre se décolle très simplement du film polyéthylène. Une
telle modification va permettre de plier deux parties du substrat 1 pour
former deux bandes de rive perpendiculaires sans excès de matière en
ce qui concerne le voile de verre et par contre en conservant un excès de
film polyéthylène, qui n'est pas gênant et au contraire garantit
l'étanchéité dans cette zone où les techniques habituelles sont souvent
très délicates de mise en oeuvre pour garantir un résultat équivalent.During installation, the
Le substrat ainsi décrit selon l'invention permet donc de réaliser une isolation acoustique efficace dans le temps d'une façon simplifiée et plus rapide que selon les techniques habituellement utilisées.The substrate thus described according to the invention therefore makes it possible to produce sound insulation effective over time in a simplified way and faster than the usual techniques.
