Description
Jusqu'a présent, on s'est heurté à de nombreuses difficultêes pour le maintien de divers revêtements formant isolants thermiques et acoustiques, le plus souvent lorsqu'il s'agit de batiments de formes diverses car il est difficile, d'une part, d'assurer une mise sous tension permanente du revêtement et, d'autre part, d'éviter des jeux provoqués par des vibrations diverses auxquelles sont soumis ces bâtiments et ce, en particulier, lorsque ces derniers sont voisins de points de travail provoquant des vibrations, d'autoroutes, de voies de chemins de fer et de pistes de de collage et d'atterrissage pour avions. Until now, many difficulties have been encountered in maintaining various coatings forming thermal and acoustic insulators, most often in the case of buildings of various shapes because it is difficult, on the one hand, to ensure a permanent tensioning of the coating and, on the other hand, to avoid games caused by various vibrations to which these buildings are subjected and this, in particular, when the latter are close to work points causing vibrations , highways, railways and aircraft bonding and landing strips.
C'est en particulier le cas dans des bâtiments de bureaux ou d'entrepots situés dans des zones de forte industrialisation, de circulation terrestre ou aérienne intense, ou il faut cependant que ces bâtiments soient revêtus, soit intérieurement, soit extérieurement, ou sur les deux côtés, de couches d'isolation thermique et sonore. This is particularly the case in office or warehouse buildings located in areas of high industrialization, intense land or air traffic, or it is however necessary that these buildings are coated, either internally, externally, or on two sides, layers of thermal and sound insulation.
La présente invention crée donc un ensemble mécanique de maintien anti-vibrations permettant le montage aisé des couches isolantes mais également leur démontage sans avarie notable pour les ensembles mécaniques de maintien anti-vibrations qui peuvent également comporter, dans leur constitution, un élément de longueur variable permettant ainsi la pose d'éléments isolants d'épaisseur différente. The present invention therefore creates a mechanical anti-vibration holding assembly allowing the easy mounting of the insulating layers but also their disassembly without significant damage for the mechanical anti-vibration holding assemblies which may also include, in their constitution, an element of variable length. thus allowing the installation of insulating elements of different thickness.
Conformément à l'invention, l'ensemble mécanique anti-vibrations pour le maintien sous tension de divers revêtements, en particulier de revêtements isolants thermiques et sonores, comporte une rondelle de répartition solidaire d'une première pièce d'espacement maintenant une tige filetée entourée par un ressort spiral dont le sens des spires est dirigé dans le sens contraire des aiguilles d'une montre et dont l'extrémité coopère avec les dents de loup portées par la partie inférieure de la première pièce d'espacement, la tige filetée étant reliée par son extrémité inférieure à une deuxième pièce d'espacement qui porte à son extrémité inférieure une pointe foreuse et taraudeuse tandis que son extrémité supérieure est munie de dents de loup coopérant avec l'autre extrémité du ressort. In accordance with the invention, the mechanical anti-vibration assembly for keeping various coatings under tension, in particular thermal and sound insulating coatings, comprises a distribution washer integral with a first spacer maintaining a threaded rod surrounded by a spiral spring whose direction of the turns is directed anticlockwise and whose end cooperates with the wolf teeth carried by the lower part of the first spacer, the threaded rod being connected by its lower end to a second spacer which carries at its lower end a drilling and tapping tip while its upper end is provided with wolf teeth cooperating with the other end of the spring.
Suivant une autre caracteristique de l'invention, l'ensemble mecanique anti-vibrations est caractérisé en ce qu'un circlip permet un blocage temporaire du ressort lors du démontage de l'ensemble mécanique. According to another characteristic of the invention, the anti-vibration mechanical assembly is characterized in that a circlip allows a temporary blocking of the spring during the disassembly of the mechanical assembly.
Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.
Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple non limitatif, aux dessins annexés. An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawings.
La fig. 1 est une vue éclatée du dispositif de maintien anti-vibrations, conforme à l'invention. Fig. 1 is an exploded view of the anti-vibration holding device according to the invention.
La fig. 2 est une élévation de face de l'ensemble mécanique de maintien. Fig. 2 is a front elevation of the mechanical holding assembly.
La fig. 3 est une vue en plan prise suivant la ligne
III-III de la fig. 2 de la tête plane supérieure de 1 'ensemble mécanique.Fig. 3 is a plan view taken along the line
III-III of fig. 2 of the upper flat head of the mechanical assembly.
La fig. 4 est une coupe suivant la ligne IV-IV de la fig. 2. Fig. 4 is a section along the line IV-IV of FIG. 2.
La fig. 5 est une coupe suivant la ligne V-V de la fig. 2. Fig. 5 is a section along the line V-V of FIG. 2.
A la fig. 1, on a représenté l'ensemble mécanique en vue éclatée et l'on peut voir, ainsi, une vis 1 à tige semi-sphérique 2 pénétrant normalement dans un trou 3 d'une rondelle de répartition 4 qui vient reposer sur l'extrémité décolletée 5a d'une pièce d'espacement supérieure cylindrique 5 dont la base 5b comporte des dents de loup 6. La pièce d'espacement cylindrique 5, qui recoit dans son canal supérieur 5d la vis 1, comporte, à sa partie inférieure, un canal élargi 5e dans lequel pénètre une tige filetée 7 de longueur variable et qui vient se glisser dans le canal élargi taraudé 5e mentionné ci-dessus. La tige filetée 7 est entourée par un ressort de compression 8 à spires 9 qui sont dirigées dans le sens contraire des aiguilles d'une montre. In fig. 1, the mechanical assembly has been shown in exploded view and one can thus see a screw 1 with a semi-spherical rod 2 normally penetrating a hole 3 of a distribution washer 4 which comes to rest on the end neck 5a of a cylindrical upper spacer 5 whose base 5b has wolf teeth 6. The cylindrical spacer 5, which receives in its upper channel 5d the screw 1, comprises, at its lower part, a enlarged channel 5e into which a threaded rod 7 of variable length enters and which slides into the enlarged tapped channel 5e mentioned above. The threaded rod 7 is surrounded by a compression spring 8 with turns 9 which are directed anti-clockwise.
Sur la partie inférieure de la tige filetée 7 vient se visser une pièce d'espacement inférieure 10 percée d'un canal central 11 permettant le vissage d'une partie de la tige filetée 7. I1 est à remarquer que la partie supérieure de la pièce d'épaisseur 10 comporte également des dents de loup 12 sur lesquelles repose normalement une bague d'arrêt 13. On the lower part of the threaded rod 7 is screwed a lower spacer 10 pierced with a central channel 11 allowing the screwing of a part of the threaded rod 7. It is to be noted that the upper part of the part of thickness 10 also includes wolf teeth 12 on which a stop ring 13 normally rests.
Finalement, la base du canal central 11 de la pièce d'épaisseur inférieure 10 recoit la tige filetée 15 d'une pointe foreuse et taraudeuse 16. Finally, the base of the central channel 11 of the piece of lower thickness 10 receives the threaded rod 15 with a drilling and tapping point 16.
A la fig. 2, l'ensemble mécanique est monté et l'on peut se rendre compte aisément qu'en section, la pièce d'espacement supérieure 5 est cylindrique (voir fig. 4) tandis que la pièce d'espacement inférieure 10 est polygonale (voir fig. 5), dans le cas présent à six pans. In fig. 2, the mechanical assembly is mounted and it can easily be seen that in section, the upper spacer 5 is cylindrical (see FIG. 4) while the lower spacer 10 is polygonal (see fig. 5), in this case hexagon.
Lorsque l'ensemble doit être mis en place pour maintenir, sur une surface quelconque, un revêtement, ce dernier est perforé de part en part par la tête 16 jusqu'au moment où la face libre du revêtement vient prendre appui sous la rondelle de répartition 4. La pointe foreuse et taraudeuse 16 a pénétré largement dans l'épaisseur de l'isolant et celui-ci se trouve donc bloqué entre la rondelle de répartition 4 et la face inférieure ou interne du support. When the assembly must be put in place to maintain, on any surface, a coating, the latter is perforated right through by the head 16 until the free face of the coating comes to bear under the distribution washer 4. The drilling and tapping point 16 has penetrated widely into the thickness of the insulation and the latter is therefore blocked between the distribution washer 4 and the lower or internal face of the support.
La force du ressort spiral 8 dont les spires 9 sont dirigées dans le sens contraire des aiguilles d'une montre permet de maintenir une pression constante sur la couche isolante même s il se produit des vibrations. En effet, les différents éléments constituant l'ensemble mécanique de support ne se desserrent pas sous les vibrations puisque le sens de dévissage de l'ensemble est contrarié par cette disposition inverse du ressort 8 dont les extrémités 8a, 8b viennent en opposition dans les dents de loup 6 et 12 prévues sur les pièces 5 et 10. The force of the spiral spring 8, the turns 9 of which are directed anticlockwise makes it possible to maintain constant pressure on the insulating layer even if vibrations occur. Indeed, the various elements constituting the mechanical support assembly do not loosen under vibrations since the direction of unscrewing of the assembly is thwarted by this reverse arrangement of the spring 8 whose ends 8a, 8b come into opposition in the teeth wolf 6 and 12 provided on parts 5 and 10.
L'ensemble résiste donc bien aux vibrations et aux chocs mais, cependant, il est possible, en resserrant le ressort 8 par l'action de la bague d'arrêt 13, de dégager l'extrémité 8b du ressort 8 des dents de loup 12 solidaires de la pièce 10 afin de pouvoir desserrer et démonter l'ensemble et donc de libérer rapidement l'élément isolant de son support, ce qui est parfois nécessaire soit pour le renforcer, soit pour le remplacer au bout d'un laps de temps déterminé. The assembly therefore withstands vibrations and shocks well but, however, it is possible, by tightening the spring 8 by the action of the stop ring 13, to release the end 8b of the spring 8 from the wolf teeth 12 integral with the part 10 in order to be able to loosen and disassemble the assembly and therefore to quickly release the insulating element from its support, which is sometimes necessary either to reinforce it, or to replace it after a determined period of time .
Le ressort 8 permet également d'assurer une compression de l'isolant suivant des valeurs prédéterminées, conformes aux normes de cet isolant. The spring 8 also makes it possible to ensure compression of the insulation according to predetermined values, in accordance with the standards of this insulation.
