Description
La présente invention a pour objet un organe de maintien et de fixation étudié pour résister aux agents considérés qui corrodent ces organes en présence d'humidité surtout lorsque la couche isolante placée entre la surface inférieure, par exemple une toiture, et la peau de revêtement, est en une matière synthétique telle que, par exemple de la mousse phénolique. The subject of the present invention is a holding and fixing member studied to resist the agents considered which corrode these members in the presence of moisture, especially when the insulating layer placed between the lower surface, for example a roof, and the covering skin is made of a synthetic material such as, for example, phenolic foam.
En effet, en présence d'humidité,- la mousse phénolique se modifie et produit un liquide acide & base d'acide phénolique qui corrode et détruit rapidement les organes de maintien et de fixation de ces couches isolantes. Indeed, in the presence of moisture, - the phenolic foam changes and produces an acidic liquid & base of phenolic acid which corrodes and destroys quickly the organs of maintenance and fixing of these insulating layers.
Or, pour des raisons diverses,- la peau supérieure peut devenir légèrement poreuse et laisser passer l'humidité d'où des dégâts importants allant jusqu' une destruction pratiquement totale du revêtement constitué par la peau et les couches d'isolants thermique et phonique. However, for various reasons, - the upper skin can become slightly porous and allow moisture to pass through, resulting in significant damage going up to practically total destruction of the coating formed by the skin and the layers of thermal and sound insulation.
On a déjd tenté de fixer de manières diverses, ces couches isolantes thermique et phonique dont on revêtait en particulier les toitures par des vis du type connu dans le commerce sous le nom de Parker avec l'aide de rondelles centrées sur la tête de la vis puis en revêtant le tout d'une peau synthétique ou naturelle par exemple un composite à base de goudron. We have already tried to fix in various ways, these thermal and sound insulating layers with which the roofs were coated in particular by screws of the type known in the trade under the name of Parker with the aid of washers centered on the head of the screw. then by coating the whole with a synthetic or natural skin, for example a tar-based composite.
Mais, sous différents incidents tels que par exemple la marche d'ouvriers sur la toiture pour des réparations, nettoyage et entretiens divers, la peau supérieure est "découpée" par les têtes de vis du fait que la rondelle de protection s'enfonce sous le poids de l'ouvrier en provoquant ainsi des passages pour l'air humide ou même l'eau de pluie, ce qui provoque très rapidement une modification chimique de la masse isolante qui est très souvent réalisée à base de masse phénolique et ainsi l'acide phénolique créé corrode et détruit les vis de maintien et de fixation allant jusqu'à la destruction parfois complète du revêtement de toiture. But, under various incidents such as for example the walk of workers on the roof for various repairs, cleaning and maintenance, the upper skin is "cut" by the screw heads because the protective washer sinks under the weight of the worker thus causing passages for humid air or even rainwater, which very quickly causes a chemical modification of the insulating mass which is very often carried out on the basis of phenolic mass and thus the acid phenolic created corrodes and destroys the retaining and fixing screws up to the sometimes complete destruction of the roof covering.
La présente invention remédie ; cet inconvénient en créant un organe de maintien et de fixation de l'isolant sur des surfaces diverses qui comporte une rondelle raidie par des gaufrages circulaires et radiaux et présentant en son centre autour de l'ouverture de passage pour la vis et servant de logement la tête de cette dernière une conformation tronconique ou autre sur laquelle vient s'adapter une entretoise circulaire couvrant la vis de façon à ce que cette dernière soit protégée de la couche d'isolant en évitant ainsi la corrosion et la destruction de la vis ainsi que l'enfoncement intempestif de l'isolant lors du serrage. The present invention remedies; this disadvantage by creating a member for holding and fixing the insulation on various surfaces which comprises a washer stiffened by circular and radial embossings and having in its center around the passage opening for the screw and serving as housing the head of the latter a frustoconical or other conformation to which is fitted a circular spacer covering the screw so that the latter is protected from the insulating layer thereby preventing corrosion and destruction of the screw as well as the inadvertent insertion of the insulation during tightening.
Conformément c l'invention, l'organe est constit-ué par une rondelle en matière résistant la corrosion présentant en son centre un évidement pénétrant dans la corolle d'une entretoise formant gaine dont la partie inférieure vient reposer sur la face supérieure de la tôle ' isoler puis on fixe le tout en des endroits convenables & l'aide soit d'une vis, soit d'un rivet. According to the invention, the member is constituted by a washer made of corrosion-resistant material having in its center a recess penetrating into the corolla of a spacer forming a sheath, the lower part of which comes to rest on the upper face of the sheet. 'isolate then fix everything in suitable places using either a screw or a rivet.
Suivant une autre caractéristique de l'invention, la vis utilisée est du type Parler permettant la pénétration dans la tôle de recouvrement sans pratiquer de pré-trous. According to another characteristic of the invention, the screw used is of the Talking type allowing penetration into the cover sheet without making pre-holes.
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.
Des formes de réalisation de l'objet de l'invention sont représentees, 2 titre d'exemples non limitatifs, aux dessins annexés. Embodiments of the object of the invention are shown, 2 by way of nonlimiting examples, in the accompanying drawings.
La fig. 1 est'unie coupe longitudinale d'une surface revêtue d'une couche d'isolant thermique et phonique montrant, dans la partie gauche, l'état antérieur de la technique avec destruction de la peau supérieure et, dans la partie droite, une première forme de réalisation de l'invention. Fig. 1 is a longitudinal section of a surface coated with a layer of thermal and sound insulation showing, in the left part, the prior art with destruction of the upper skin and, in the right part, a first embodiment of the invention.
La fig. 2 est une vue en perspective de la rondelle munie de son entretoise et de la vis de fixa- tion. Fig. 2 is a perspective view of the washer provided with its spacer and the fixing screw.
La fig. 2a est une coupe diamétrale de la rondelle. Fig. 2a is a diametrical section of the washer.
La fig. 2b est une élévation de face de la gaine formant entretoise. Fig. 2b is a front elevation of the sheath forming a spacer.
La fig. 3 est une variante de l'organe de maintien et de fixation à l'aide d'un rivet. Fig. 3 is a variant of the holding and fixing member using a rivet.
La fig. 4 est une coupe, à plus petite échelle, d'une surface revêtue de l'isolant thermique et phonique fixé à l'aide de rondelles, d'entretoises et de rivets conformes à l'invention. Fig. 4 is a section, on a smaller scale, of a surface coated with thermal and sound insulation fixed using washers, spacers and rivets according to the invention.
A la fig. 1, on a représenté partiellement une toiture de bâtiment, par exemple un bâtiment de stockage, un atelier ou autres, qui est constituée par une surface métallique ondulée 1 qui, en général, est une tôle d'acier qui est revêtue sur sa face. supérieure la d'une mousse isolante 2 thermique et phonique du commerce qui est réalisée en différents matériaux mais assez souvent une mousse phénolique. In fig. 1, a building roof is partially shown, for example a storage building, a workshop or the like, which is constituted by a corrugated metal surface 1 which, in general, is a sheet of steel which is coated on its face. the upper of a commercial thermal and phonic insulating foam 2 which is made of different materials but quite often a phenolic foam.
Cette masse isolante est maintenue sur la surface métallique ondulée 1 jusqu'a présent par des rondelles 3 présentant en son centre un trou 4 à travers lequel passe une vis 5 (voir partie gauche de la fig. 1). This insulating mass is maintained on the corrugated metal surface 1 until now by washers 3 having in its center a hole 4 through which passes a screw 5 (see left part of fig. 1).
Le tout est revêtu d'une manière connue en soi par une peau supérieure de recouvrement 6, en général réalisée à partir d'un produit bitumineux mais qui, sous l'effet d'un poids par exemple le poids d'un ouvrier, se déchire du fait que la tête de vis découpe la peau supérieure de recouvrement 6 lorsque la rondelle 3 s'enfonce suivant les flèches. The whole is coated in a manner known per se by an upper covering skin 6, generally made from a bituminous product but which, under the effect of a weight for example the weight of a worker, is tears because the screw head cuts the upper cover skin 6 when the washer 3 sinks in according to the arrows.
Il s'ensuit que de l'humidité peut pénétrer à travers la mousse isolante 2 et si celle-ci, en présence d'eau, donne un mélange corrosif ce qui est le cas pour les mousses phénoliques, les vis 5 sont détruites rapidement et l'ensemble de recouvrement formant l'isolement thermique et phonique risque de se détacher complètement du toit et de tomber provoquant ainsi des accidents graves. It follows that moisture can penetrate through the insulating foam 2 and if this, in the presence of water, gives a corrosive mixture which is the case for phenolic foams, the screws 5 are destroyed quickly and the cover assembly forming the thermal and sound insulation may completely detach from the roof and fall, causing serious accidents.
La présente invention a donc pour objet de proposer une rondelle 10 (voir fig. 2) dont la surface est raidie radialement et circonférentiellement par des gaufrages 11, 12 et qui présentent en son centre un évidement 13 en forme d'entonnoir sur la partie infé-rieure duquel vient s'accrocher une entretoise 14 formant gaine terminée a' sa partie supérieure par une corolle 15 et la vis 16 qui est du genre Parker est donc noyée à l'intérieur de l'entretoise 14 formant gaine, ce qui fait que lorsque la vis 16 est en place, comme le montre la partie droite de la fig. 1, même si un ouvrier circule sur le toit la rondelle ne peut pas s'abaisser du fait que l'entretoise 14 prend appui sur la face supérieure du toit métallique ondulé 1 et qu'ainsi la peau supérieure de recouvrement 6 ne peut pas être détériorée. The present invention therefore aims to provide a washer 10 (see Fig. 2) whose surface is stiffened radially and circumferentially by embossments 11, 12 and which have at its center a recess 13 in the form of a funnel on the lower part -rieure which hangs a spacer 14 forming a sheath terminated at its upper part by a corolla 15 and the screw 16 which is of the Parker type is therefore embedded inside the spacer 14 forming a sheath, which means that when the screw 16 is in place, as shown in the right part of FIG. 1, even if a worker travels on the roof, the washer cannot be lowered because the spacer 14 is supported on the upper face of the corrugated metal roof 1 and thus the upper covering skin 6 cannot be deteriorated.
On assure ainsi, par des moyens simples, la protection contre l'humidité de la masse isolante 2 et même si celle-ci est réalisée en mousse phénolique la vis 16 ne peut en aucun cas être détériorée. This provides, by simple means, protection against moisture of the insulating mass 2 and even if it is made of phenolic foam the screw 16 can in no way be damaged.
En général, la rondelle 10, l'entretoise 14 et sa corolle 15 sont fabriquées en un matériau résistant aux agents considérés, par exemple en aluminium traité, en matière plastique ou en métal inoxydable. In general, the washer 10, the spacer 14 and its corolla 15 are made of a material resistant to the agents considered, for example treated aluminum, plastic or stainless metal.
Dans le cas où on utilise une rondelle 10 avec une entretoise 14 et que l'on remplace la vis 16 par un rivet 20 (voir fig. 4) on pratique d'abord un trou 21 a' l'aide d'un foret 22 monté sur un perceuse 23 puis on place ensuite sous la peau 6, la rondelle 10, l'entretoise 14 et l'on fixe le rivet 20 d'une manière connue en soi. In the case where a washer 10 is used with a spacer 14 and the screw 16 is replaced by a rivet 20 (see fig. 4), a hole 21 is first made using a drill 22 mounted on a drill 23 and then placed under the skin 6, the washer 10, the spacer 14 and the rivet 20 is fixed in a manner known per se.
En utilisant l'organe de fixation et de maintien de l'invention, on obtient une étanchéité parfaite et enaucun cas le revêtement isolant thermique et phonique ne peut se séparer de la face supérieure la de la tôle 1. By using the fixing and holding member of the invention, a perfect seal is obtained and in no case can the thermal and sound insulating coating be separated from the upper face 1a of the sheet 1.
