Description
DISPDSITIF DE FIXATION ISOLANT
L'invention concerne un dispositif de fixation isolant d'un élément de structure chaud sur une paroi de réservoir en matériau thermiquement fusible au moyen d'une vis de fixation.INSULATING FIXING DEVICE
The invention relates to an insulating fixing device for a hot structural element on a tank wall made of thermally fusible material by means of a fixing screw.
On connalt un dispositif de fixation isolant dans lequel une rondelle polyamide chargée de fibres de verre ou d'amiante, traversée une vis de fixation, est intercalée entre un élément fusible à cette même température. Dans les liaisons de ce type, la vis de fixation constitue un conducteur de chaleur susceptible de détériorer le filetage porté par l'élément thermiquement sensible.An insulating fixing device is known in which a polyamide washer loaded with glass fibers or asbestos, crossed by a fixing screw, is interposed between a fusible element at this same temperature. In connections of this type, the fixing screw constitutes a heat conductor capable of damaging the thread carried by the thermally sensitive element.
Conformément à l'invention cet inconvénient est à éliminé par le fait que le tronçon fileté de la vis est engagé dans un plot isolant loge dans un support de fixation rapporté sur la paroi du réservoir.In accordance with the invention, this drawback is eliminated by the fact that the threaded section of the screw is engaged in an insulating stud housed in a fixing support attached to the wall of the tank.
D'autres caractéristiques de l'invention apparaîtront à la lecture de la description faite en référence au dessin annexé dans lequel - la figure 1, est une coupe axiale du dispositif de fixation conforme à l'état de la technique antérieur - la figure 2, est une coupe axiale du dispositif de fixation conforme à l'invention.Other characteristics of the invention will appear on reading the description made with reference to the appended drawing in which - FIG. 1 is an axial section of the fixing device in accordance with the state of the prior art - FIG. 2, is an axial section of the fixing device according to the invention.
Sur les figures 1 et 2, on voit une partie d'un réservoir défini par sa paroi 1. Sur la paroi 1 sont rapportées par soudure des supports de fixation 2, réalisés dans la matière constitutive du réservoir tel qu'une matière plastique. Un élément de structure chaud tel qu'un écran thermique 3 est constitué par une tôle et isole la paroi 1 d'une source de chaleur rayonnante telle qu'une tubulure d'échappement 4. Le tronçon fileté de la vis de fixation 5 est vissé selon la figure 1, dans le support 2 après interposition d'une rondelle isolante 6 en polyamide chargé de fibre de verre.In Figures 1 and 2, we see a part of a tank defined by its wall 1. On the wall 1 are attached by welding of the mounting brackets 2, made of the material of the tank such as plastic. A hot structural element such as a heat shield 3 is constituted by a sheet and insulates the wall 1 from a radiant heat source such as an exhaust pipe 4. The threaded section of the fixing screw 5 is screwed according to Figure 1, in the support 2 after interposition of an insulating washer 6 in polyamide loaded with glass fiber.
Selon la figure 2, le tronçon fileté de la vis est engagé dans un plot isolant 10 en polyamide chargé de fibre de verre monté dans le support 2.According to FIG. 2, the threaded section of the screw is engaged in an insulating stud 10 of polyamide loaded with glass fiber mounted in the support 2.
Les ensembles constitués par le plot 10 et le support 2 sont préassemblés avant leur liaison à la paroi I. A cet effet, le support 2 possède un perçage axial 11 dont l'extrémité évasée 12 assure la rétention axiale du plot 10. The assemblies constituted by the stud 10 and the support 2 are preassembled before their connection to the wall I. For this purpose, the support 2 has an axial bore 11 whose flared end 12 ensures the axial retention of the stud 10.
