Description

Structure de joint coupe-feu en boudin  Flange fire joint structure
La présente invention concerne une structure de joint coupe-feu en boudin notamment pour l'industrie de la construction immobilière. The present invention relates to a flange fire joint structure in particular for the 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.  It is known that there already exist in the state of the art firewall structures of this nature that are used to seal voids, holes .... and constitute fire barriers between different building elements for example, to prevent it from spreading.
Ces structures de joint 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 joint structures are for example currently made by winding a sheet of fibers in the form of a bead or a bead and maintaining the shape of the bead or bead using a layer of fibers wound around this sheet .
Cependant, on conçoit que ces structures présentent un certain nombre d'inconvénients notamment au niveau de la qualité du joint obtenu et de la difficulté de fabrication de celle-ci et donc de son coût de fabrication.  However, it is conceivable that these structures have a number of disadvantages, particularly in terms of the quality of the joint obtained and the difficulty of manufacturing thereof and therefore its manufacturing cost.
Le but de l'invention est donc de résoudre ces problèmes.  The object of the invention is therefore to solve these problems.
A cet effet, l'invention a pour objet une structure de joint coupe-feu en boudin notamment pour l'industrie de la construction immobilière, caractérisée en ce qu'elle 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.  For this purpose, the subject of the invention is a flanged fire-joint structure, particularly for the building construction industry, characterized in that it is in the form of an outer envelope comprising two associated layers of which one internal is formed by a grid of fibers and the other outer is formed by a knitted layer of fibers and in which insulating wool is placed in bulk.
Selon d'autres caractéristiques de la structure suivant l'invention prises seules ou en combinaison :  According to other features of the structure according to the invention taken alone or in combination:
- la fibre est de la fibre de verre ;  fiber is fiberglass;
- la fibre est de la fibre de silice ;  the fiber is silica fiber;
- la laine en vrac est de la laine de roche ;  - loose wool is rockwool;
- la laine en vrac est de la laine broyée ;  - loose wool is ground wool;
- la grille est colorée ;  - the grid is colored;
- la laine en vrac est placée sur la grille à plat qui est ensuite refermée sur elle- même et maintenue fermée par la couche tricotée ;  - The loose wool is placed on the flat grid which is then closed on itself and kept closed by the knitted layer;
- la couche tricotée est réalisée à l'aide d'une machine à quatre aiguilles et à mailles ouvertes ;  the knitted layer is made using a machine with four needles and open meshes;
- la jonction de deux tronçons de joints est réalisée par enroulement dans une pièce de fibres.  - The junction of two sections of joints is made by winding in a piece of fibers.
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 with reference to the appended drawing which represents a perspective view with torn portions of an exemplary embodiment of a fire seal structure according to the invention.
On a en effet illustré sur cette figure une structure de joint coupe-feu en boudin ou en cordon notamment utilisable dans l'industrie de la construction immobilière pour constituer une barrière coupe-feu.  It has in fact shown in this figure a firewall seal structure or coil particularly used in the construction industry to build a fire barrier.
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 deux couches associées.  This structure is designated by the general reference 1 in this figure and it is then in the form of an outer envelope designated by the general reference 2, comprising two associated layers.
L'une des couches associées est une couche interne désignée par la référence générale 3, et est formée par une grille de fibre.  One of the associated layers is an inner layer designated by the general reference 3, and is formed by a fiber grid.
L'autre des couches associées est une couche externe désignée par la référence générale 4, et est formée par une couche tricotée de fibres.  The other of the associated layers is an outer layer designated by the general reference 4, and is formed by a knitted fiber layer.
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 être envisagés. Different embodiments of these different elements can be envisaged.
Ainsi, par exemple, la fibre peut être de la fibre de verre ou de la fibre de silice ou autre. Thus, for example, the fiber may be fiberglass or silica fiber or the like.
La laine en vrac peut quant à elle être de la laine broyée telle que par exemple de la laine de roche.  Bulk wool can be ground wool such as for example rock wool.
La grille de fibres peut quant à elle être colorée.  The fiber grid can be colored.
On peut en effet prévoir des couleurs différentes de grille permettant de reconnaître/identifier l'une des caractéristiques de la structure de joint comme par exemple son diamètre ou autre.  We can indeed provide different colors of grid to identify / identify one of the characteristics of the joint structure such as its diameter or other.
Selon un procédé de fabrication possible d'une telle structure de joint coupe-feu, la laine en vrac par exemple peut être placée sur la grille de fibres qui est alors posée à plat et qui est ensuite refermée sur elle-même pour former le boudin ou cordon en utilisant par exemple un organe en forme d'entonnoir ou autre, à travers lequel l'ensemble grille-laine est amené à passer.  According to a method of possible manufacture of such a fire seal structure, loose wool for example can be placed on the fiber grid which is then laid flat and which is then closed on itself to form the flange or cord using for example a funnel-shaped member or the like, through which the grid-wool assembly is passed.
La grille étant ensuite maintenue fermée autour de la laine, par la couche tricotée en fibres au-dessus de cette grille.  The grid is then kept closed around the wool, by the knitted fiber layer above this grid.
La grille en fibres sert alors à maintenir la laine dans le boudin ou le cordon.  The fiber grid is then used to hold the wool in the bead or cord.
Cette laine est en effet en vrac mais ne peut pas passer à travers le maillage très serré de la grille.  This wool is indeed loose but can not pass through the very tight mesh of the grid.
La couche tricotée en fibres sert quant à elle à maintenir la grille fermée et donc la structure sous la forme d'un cordon ou d'un boudin. Cette couche tricotée peut par exemple être réalisée à l'aide d'une machine à tricoter à quatre aiguilles et à mailles ouvertes. The knitted fiber layer serves to keep the grid closed and thus the structure in the form of a cord or a bead. This knitted layer may for example be made using a knitting machine with four needles and open meshes.
Bien entendu d'autres modes de réalisation encore peuvent être envisagés.  Of course other embodiments can be envisaged.
On notera également que la jonction de deux tronçons de joints tels que décrits peut être réalisée par enroulement dans une pièce de fibres autour de la zone de raboutement de ces tronçons de joints.  It will also be noted that the junction of two sections of joints as described can be made by winding in a piece of fibers around the splicing zone of these joint sections.
