Description
La présente invention concerne une structure de joint coupe-feu notamment pour l’industrie de la construction immobilière.The present invention relates to a fire joint structure, in particular for the building construction industry.
On sait qu’il existe déjà dans l’état de la technique, des structures de joints coupe-feu de cette nature qui sont utilisées pour obturer des vides, des trous…. et constituer des barrières coupe-feu entre différents éléments de construction par exemple, afin d’éviter que celui-ci ne se propage.We know that there are already in the state of the art, structures of fire seals of this nature which are used to seal voids, holes, etc. and build fire barriers between different construction elements, for example, to prevent it from spreading.
Ces structures de joint coupe-feu sont par exemple actuellement réalisées par enroulement d’une nappe de fibres sous la forme d’un boudin ou d’un cordon et maintien de la forme du boudin ou du cordon en utilisant une couche de fibres enroulées autour de cette nappe.These fire seal structures are, for example, currently produced by winding a layer of fibers in the form of a sausage or a cord and maintaining the shape of the sausage or cord by using a layer of fibers wound around of this sheet.
La Demanderesse a également proposé dans le document FR 3 024 947, une structure de joint coupe-feu en boudin notamment pour l’industrie de la construction immobilière, qui se présente sous la forme d’une enveloppe externe comportant deux couches associées dont l’une interne est formée par une grille de fibres et dont l’autre externe est formée par une couche tricotée de fibres et dans laquelle est placée de la laine isolante en vrac.The Applicant has also proposed, in document FR 3 024 947, a bead firestop joint structure, in particular for the building construction industry, which is in the form of an outer envelope comprising two associated layers, the an internal one is formed by a grid of fibers and the other external is formed by a knitted layer of fibers and in which is placed loose insulating wool.
Des voiles de fibres peuvent également être utilisés avec, en combinaison ou à la place de la grille.Fiber veils can also be used with, in combination or instead of the grid.
Le but de l’invention est de perfectionner encore ce type de structures.The object of the invention is to further improve this type of structure.
A cet effet, l’invention a pour objet une structure de joint coupe-feu notamment pour l’industrie de la construction immobilière, comprenant une enveloppe externe comportant au moins une couche tricotée de fibres et dans laquelle est placée de la laine isolante en vrac, caractérisée en ce que la couche tricotée de fibres est au moins en partie colorée.To this end, the subject of the invention is a fireproof seal structure, in particular for the building construction industry, comprising an outer envelope comprising at least one knitted layer of fibers and in which loose insulating wool is placed. , characterized in that the knitted layer of fibers is at least partly colored.
Selon d’autres caractéristiques de la structure suivant l’invention prises seules ou en combinaison :According to other characteristics of the structure according to the invention taken alone or in combination:
- la couche tricotée de fibres comporte des portions présentant des pas de fibres différents ;the knitted layer of fibers comprises portions having different fiber pitches;
- la fibre est en un matériau ignifuge ;the fiber is made of a flame retardant material;
- la fibre est en un matériau choisi dans le groupe comprenant en outre :the fiber is made of a material chosen from the group further comprising:
- du verre,glass,
- de la silice,silica,
- du coton,cotton,
- du polypropylène,polypropylene,
- du polyester,polyester,
- du polyuréthane,polyurethane,
- de l’aramide,aramid,
- de la roche,rock,
- du carbone ;carbon;
- la laine en vrac est de la laine minérale ;loose wool is mineral wool;
- la laine est de la laine de roche ;the wool is rock wool;
- la laine en vrac est de la laine cardée ;loose wool is carded wool;
- la couche tricotée de fibres est placée autour d’une gaine de maintien de la laine ;the knitted layer of fibers is placed around a sheath to hold the wool;
- la gaine est formée par au moins une grille et/ou un voile de fibres.the sheath is formed by at least one grid and/or a web of fibres.
L’invention sera mieux comprise à l’aide de la description qui va suivre donnée uniquement à titre d’exemple et faite en se référant au dessin annexé qui représente une vue en perspective avec des portions arrachées, d’un exemple de réalisation d’une structure de joint coupe-feu selon l’invention.The invention will be better understood with the aid of the following description given solely by way of example and made with reference to the appended drawing which represents a perspective view with portions cut away, of an example embodiment of a fire joint structure according to the invention.
On a en effet illustré sur cette figure, une structure de joint coupe-feu par exemple en boudin ou en cordon notamment utilisable dans l’industrie de la construction immobilière pour constituer une barrière coupe-feu.In fact, this figure illustrates a firestop joint structure, for example made of sausage or cord, which can be used in particular in the building construction industry to form a firestop barrier.
En effet ces structures sont utilisées pour constituer des barrières coupe-feu entre différents éléments de construction par exemple, afin d’éviter que celui-ci ne se propage dans la construction.Indeed, these structures are used to constitute fire barriers between different construction elements, for example, in order to prevent it from spreading in the construction.
Cette structure est désignée par la référence générale 1 sur cette figure et elle se présente alors sous la forme d’une enveloppe externe désignée par la référence générale 2, comportant par exemple deux couches associées.This structure is designated by the general reference 1 in this figure and it then takes the form of an outer envelope designated by the general reference 2, comprising for example two associated layers.
L’une des couches associées est une couche interne désignée par la référence générale 3, et est formée par une gaine ou un manchon de fibres ou de fils.One of the associated layers is an internal layer designated by the general reference 3, and is formed by a sheath or a sleeve of fibers or yarns.
Cette gaine ou manchon peut alors comporter au moins une grille et/ou un voile de fibres.This sheath or sleeve can then comprise at least one grid and/or a web of fibers.
Dans la présente demande les termes fibres et fils doivent être considérés comme équivalents.In the present application, the terms fibers and yarns must be considered equivalent.
Ils peuvent être d’origine naturelle ou synthétique.They can be of natural or synthetic origin.
L’autre des couches associées est une couche externe désignée par la référence générale 4, et est formée par une couche tricotée de fibres ou de fils.The other of the associated layers is an outer layer designated by the general reference 4, and is formed by a knitted layer of fibers or yarns.
De la laine isolante en vrac est placée dans cette enveloppe externe, cette laine isolante en vrac étant désignée par la référence générale 5.Bulk insulating wool is placed in this outer casing, this bulk insulating wool being designated by the general reference 5.
Différents modes de réalisation de ces différents éléments peuvent bien entendu être envisagés.Different embodiments of these different elements can of course be envisaged.
Ainsi, par exemple, la fibre est en un matériau ignifuge.Thus, for example, the fiber is made of a flame retardant material.
La fibre est alors en un matériau choisi dans le groupe comprenant en outre :The fiber is then made of a material chosen from the group further comprising:
- du verre,glass,
- de la silice,silica,
- du coton,cotton,
- du polypropylène,polypropylene,
- du polyester,polyester,
- du polyuréthane,polyurethane,
- de l’aramide,aramid,
- de la roche,rock,
- du carbone.carbon.
La laine en vrac peut quant à elle être de la laine cardée telle que par exemple de la laine minérale.The bulk wool can itself be carded wool such as for example mineral wool.
Ainsi on peut utiliser par exemple de la laine de roche.Thus, for example, rock wool can be used.
La couche tricotée de fibres ou de fil peut quant à elle être au moins en partie colorée.The knitted layer of fibers or yarn can itself be at least partly colored.
On peut en effet prévoir des couleurs différentes de fibres ou de fils permettant de reconnaitre/identifier l’une des caractéristiques de la structure de joint comme par exemple ses propriétés coupe-feu, son diamètre ou autre.It is indeed possible to provide different colors of fibers or threads making it possible to recognize/identify one of the characteristics of the joint structure such as for example its fireproof properties, its diameter or other.
La couche tricotée de fibres ou de fils peut également comporter des portions présentant des pas de fibres différents.The knitted layer of fibers or yarns may also include portions having different fiber pitches.
La couche tricotée en fibres ou en fils sert alors par exemple à maintenir la structure sous la forme d’un cordon ou d’un boudin ce qui permet de renforcer ou « maintenir » le produit pour faciliter la mise en place sur chantier.The knitted layer of fibers or yarns then serves, for example, to maintain the structure in the form of a cord or a sausage, which makes it possible to reinforce or “maintain” the product to facilitate installation on site.
Ceci permet alors de sécuriser ou de préserver le produit lors de la mise en place sur chantier. Il est renforcé pour éviter qu’il se dégrade et perde donc ses propriétés coupe-feu (Par exemple un cordon qui s’éventre suite à une mise en place trop rugueuse…)This then makes it possible to secure or preserve the product during installation on site. It is reinforced to prevent it from degrading and therefore losing its fire-resistant properties (for example, a cord that splits following too rough installation, etc.)
Cette couche tricotée peut par exemple être réalisée à l’aide d’une machine à tricoter à quatre aiguilles et à mailles ouvertes de type connu en soi.This knitted layer can for example be produced using a knitting machine with four needles and open stitches of a type known per se.
Bien entendu d’autres modes de réalisation encore peuvent être envisagés.Of course, still other embodiments can be envisaged.
