    [0001] FIELD OF THE INVENTION The present invention relates to a gasket firewall structure in particular for the construction industry.
    [0002] 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. 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 . 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. The object of the invention is therefore to solve these problems. 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. According to other features of the structure according to the invention taken alone or in combination: the fiber is fiberglass; the fiber is silica fiber; loose wool is rockwool; loose wool is ground wool; the grid is colored; the loose wool is placed on the flat grid which is then closed on itself and kept closed by the knitted layer; the knitted layer is made using a machine with four needles and open meshes; the junction of two sections of joints is made by winding in a piece of fibers.
    [0003] 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 shows a perspective view with torn portions of an exemplary embodiment. a fire seal structure according to the invention. It has in fact shown in this figure a firewall seal structure or coil particularly used in the building construction industry to 5 constitute a fire barrier. 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. One of the associated layers is an inner layer designated by the general reference 3, and is formed by a fiber grid. The other of the associated layers is an outer layer designated by the general reference 4, and is formed by a knitted fiber layer. Bulk insulating wool is placed in this outer casing, this bulk insulating wool being designated by the general reference 5.
    [0004] Different embodiments of these different elements can be envisaged. Thus, for example, the fiber may be fiberglass or silica fiber or the like. Bulk wool can be ground wool such as for example rock wool.
    [0005] The fiber grid can be colored. We can indeed provide different colors of grid to recognize / identify one of the characteristics of the joint structure such as its diameter or other. According to a possible method of manufacturing such a fire seal structure, loose wool, for example, can be placed on the fiber grid which is then laid flat and then closed again to form the coil or cord using for example a funnel-shaped member or the like, through which the grid-wool assembly is passed. The grid is then kept closed around the wool, by the knitted fiber layer 30 above this grid. The fiber grid is then used to hold the wool in the bead or cord. This wool is indeed loose but can not pass through the very tight mesh of the grid. The knitted fiber layer serves to keep the grid closed and thus the structure in the form of a bead or a bead.
    [0006] This knitted layer may for example be made using a knitting machine with four needles and open meshes. Of course other embodiments can be envisaged. It will also be noted that the junction of two sections of joints as described can be carried out by winding in a piece of fibers around the splicing zone of these joint sections. 10
