Abstract
Description
La pose de tuyauteries de canalisation, de conducteurs variés dans des locaux d'habitation, nécessite La mise en place de supports, généralement des colliers de fixation, qui sont attelés aux parois du Local (mur ou plafond). L'attelage de ces dispositifs est réalisé par le scellement ou le chevillage, dans le matériau de la paroi, d'un insert possédant soit une tige filetée, soit un orifice taraudé avec lequel L'un des demi-colliers du dispositif est attelé par vissage. The installation of pipework, various conductors in residential premises, requires the installation of supports, generally fixing collars, which are coupled to the walls of the Local (wall or ceiling). The coupling of these devices is achieved by sealing or pegging, in the wall material, an insert having either a threaded rod or a threaded orifice with which one of the half-collars of the device is coupled by screwing.
Or l'évolution des matériaux de construction, liée aux caractéristiques d'isolation et de Légèreté requises dans les bâtiments modernes conduit au fait que certaines parois présentent des faces en matériau léger du genre polystyrène expansé ou produit alvéolaire dans lesquels il n a pas été possible jusqu'à ce jour d'assujettir fermement des dispositifs de fixation. C'est notamment le cas de parois horizontales (planchers) des constructions individuelles o ù la face inférieure formant Le plafond d'un sous-sol ou d'un vide sanitaire présente directement à la vue des ourdis (entrevous) en polystyrène, entre des poutreLles de béton armé précontraint auxquelles il n'est pas autorisé de fixer des supports pour ne pas en modifier les caractéristiques
mécaniques.L'installation des canalisations dans le local nécessite Leur fixation le long des parois latérales ou au sol si ce dernier n' est qu'un vide sanitaire ce qui est relativement mal commode et peu rationnel.However, the evolution of construction materials, linked to the characteristics of insulation and lightness required in modern buildings leads to the fact that certain walls have faces made of light material of the expanded polystyrene type or cellular product in which it was not possible until '' to date firmly fasten fasteners. This is particularly the case of horizontal walls (floors) of individual constructions where the underside forming the ceiling of a basement or a crawl space presents directly in view of the polystyrene wadding (between) prestressed reinforced concrete beams to which it is not authorized to fix supports so as not to modify their characteristics
The installation of the pipes in the room requires their fixing along the side walls or on the ground if the latter is only a crawl space which is relatively inconvenient and not very rational.
L'invention entend remédier à cet inconvénient en proposant un dispositif qui permet de fixer de telles canalisations directenent à ce type de matériau qui présente une faible résistance à l'arrachement. The invention intends to remedy this drawback by proposing a device which makes it possible to fix such pipes directly to this type of material which has a low resistance to tearing.
A cet effet, l'invention a donc pour objet un élément d'ancrage de la tige de fixation d'un support dans un matériau présentant une faible résistance à l'arrachement, tel par exemple qu'un matériau en polystyrène ex pansé. Selon l'une des caractéristiques de l'invention, cet élément est constitué par une semelle pourvue en son centre d'un orifice traversant destiné à recevoir Ladite tige et par au moins un fil, conformé en hélice cylindrique autour de l'axe de
L'orifice et solidaire par l'une de ses extrémités de ladite semelle tandis que son autre extrémité est effilée.To this end, the subject of the invention is therefore an element for anchoring the rod for fixing a support in a material having a low resistance to tearing, such as for example a polystyrene material which has been coated. According to one of the characteristics of the invention, this element consists of a sole provided in its center with a through hole intended to receive said rod and by at least one wire, shaped in a cylindrical helix around the axis of
The orifice and secured by one of its ends to said sole while its other end is tapered.
De préférence, L'élément selon L'invention présentera deux fils hélicoidaux de pas égal décalés de 180 . Preferably, the element according to the invention will present two helical wires of equal pitch offset by 180.
L'orifice de fixation de la tige peut etre taraudé ou coopérer élastiquement à la retenue de la tige. Une variante de l'invention consiste à prévoir sur la semelle, au lieu de L'orifice taraudé, un embout male fileté permettant le vissage d'un demi-collier présentant de manière connue une embase taraudée. The rod fixing hole can be tapped or cooperate elastically to retain the rod. A variant of the invention consists in providing on the sole, instead of the threaded orifice, a threaded male end allowing the screwing of a half-collar having in known manner a threaded base.
L'invention sera mieux comprise au cours de la description donnée ci-apres à titre d'exemple purement indicatif et non limitatif qui permettra d'en dégager les avantages et les caractéristiques secondaires. The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will make it possible to identify the advantages and the secondary characteristics thereof.
IL sera fait référence aux dessins annexés dans
Lesquels :
- la figure 1 illustre un mode de réalisation de l'invention,
- la figure 2 en montre une variante préférée de réalisation
- la figure 3 est une vue suivant F de la figure 2,
- la figure 4 est une vue en coupe de l'élément de la figure 2.Reference will be made to the accompanying drawings in
Which :
FIG. 1 illustrates an embodiment of the invention,
- Figure 2 shows a preferred embodiment
FIG. 3 is a view along F of FIG. 2,
- Figure 4 is a sectional view of the element of Figure 2.
En se reportant tout d'abord à La figure 2, on voit un élément selon L'invention constitué par une semelle 1, ici en forme de disque, comportant en son centre un orifice 2 d'axe 3, et par un fil hélicoidal 4 de section poLygonale carrée rectangulaire ou en forme de losange....). L'hélice décrite par le fil 4 est cylindrique d'axe 3 et son diamètre intérieur D est supérieur au diamètre de L'orifice 2. Il sera intéressant de prévoir ce diamètre D de dimension voisine de celle du diamètre de La semelle 1 de manière à disposer d'une grande longueur pour le fil hélicoidal 4 et ainsi d'une surface importante de contact entre ce fil e t le m a t é - riau dans lequel il est inséré.A l'une de ses extrémités, le fil 4 est solidaire de la semelle 1 tandis que son extrémité Libre 4a est effilée en une pointe acérée. Ce fil peut être métallique et noyé dans la semelle en matière plastique par son extrémité correspondante ou peut etre en une seule pièce en matière plastique avec ladite semelle. Par ailleurs, pour augmenter La Longueur de L'orifice 2, La se rrelle peut présenter une portion tubulaire 5 prolongeant L'orifice 2 du côté du fil 4. Referring first to Figure 2, we see an element according to the invention consisting of a sole 1, here in the form of a disc, having in its center an orifice 2 of axis 3, and by a helical wire 4 with rectangular or diamond-shaped square polygonal section ....). The propeller described by the wire 4 is cylindrical with an axis 3 and its internal diameter D is greater than the diameter of the orifice 2. It will be advantageous to provide this diameter D of dimension close to that of the diameter of the sole 1 so to have a great length for the helical wire 4 and thus a large contact surface between this wire and the material in which it is inserted. At one of its ends, the wire 4 is integral with the sole 1 while its free end 4a is tapered into a sharp point. This wire can be metallic and embedded in the plastic sole by its corresponding end or can be in one piece of plastic with said sole. Furthermore, to increase the length of the orifice 2, the rrelle may have a tubular portion 5 extending the orifice 2 on the side of the wire 4.
La mise en place de l'élément d'ancrage dans une paroi 6 de matériau du genre polystyrène expansé s' opère, à la main par vissage du fil 4 dans Le matériau. Du fait de la petite section du fil par rapport au diamètre de l'hélice et de sa pointe acérée, ce dernier pénètre sans déchirer Le produit et s'y trouve placé à la fin du vissage en contact intime nécessaire à l'existence de forces de frottement suffisante pour Le retenir. En outre, la pénétration du fil, sans déchirure du matériau, conserve à ce dernier, autour du fil, une cohésion aussi grande que possible qui permet d'offrir un maximum de résistance à l'arrachement en direction axiale. The positioning of the anchoring element in a wall 6 of material of the expanded polystyrene type takes place, by hand, by screwing the wire 4 into the material. Due to the small section of the wire compared to the diameter of the propeller and its sharp point, the latter penetrates without tearing The product and is placed there at the end of the screwing in intimate contact necessary for the existence of forces enough friction to hold it. In addition, the penetration of the wire, without tearing the material, keeps the latter, around the wire, as large a cohesion as possible which allows to offer a maximum resistance to tearing in the axial direction.
L'orifice 2 constitue alors un moyen d'attelage pour un organe de fixation, par exemple un collier pour une canalisation ou une tuyauterie, dont un demi-collier 7 repré senté partiellement sur La figure 1 est pourvu d'une tige 7a destinée à coopérer avec L'orifice 2. La tige 7a est ici représentée schématiquement élastiquement déformable pour pénétrer dans L'orifice 2 de manière que des griffes d'extrémité 7b puissent s'encliqueter derrière l'épaulement que constitue l'extrémité 5a de la partie tubulaire 5. The orifice 2 then constitutes a coupling means for a fixing member, for example a collar for a pipe or piping, of which a half-collar 7 partially represented in FIG. 1 is provided with a rod 7a intended to cooperate with the orifice 2. The rod 7a is here shown schematically elastically deformable to penetrate into the orifice 2 so that the end claws 7b can snap behind the shoulder which constitutes the end 5a of the tubular part 5.
Sur Les figures 2, 3 et 4 on a représenté une variante préférée de réalisation de L'élément selon l'inven- tion qui comporte deux fils héiicoidaux 4 et 4' associés à la semelle 1. Ces fils, identiques dans leur forme et leur longueur, sont décalés de 180" l'un par rapport à L'autre autour de l'axe 3. Le pouvoir d'ancrage de l'élément est ainsi augmenté. On mentionnera, à titre d'exemple, qu'un tel élément, ayant une semelle 1 de 30 miLLimètres di diamètre, un diamètre extérieur d'hélice de 28 millimètres, une longueur d'ancrage mesurée selon L'axe 3 de 50 millimètres environ, un pas d'hélice de 20 millimètres, un diamètre D intérieur d'hélice de l'ordre de 20 miLLimètres, mis en place dans environ 4 centimètres de polystyrène expansé présente une résistance à l'arrachement de l'ordre de 50 kg. Figures 2, 3 and 4 show a preferred embodiment of the element according to the invention which comprises two helical son 4 and 4 'associated with the sole 1. These son, identical in their shape and length, are offset by 180 "relative to each other around the axis 3. The anchoring power of the element is thus increased. It will be mentioned, by way of example, that such an element , having a sole 1 of 30 millimeters in diameter, an outer helix diameter of 28 millimeters, an anchor length measured along axis 3 of about 50 millimeters, a helix pitch of 20 millimeters, an inner diameter D of helix of the order of 20 millimeters, placed in about 4 centimeters of expanded polystyrene has a tear resistance of the order of 50 kg.
Par ailleurs, on voit sur ces figures que la partie tubulaire 5 se prolonge par quatre parois minces 8a, 8b, 8c, 8d qui convergent par leur extrémité effilée sur l'axe 3 en un point 9 situé au-delà de l'extrémité 4a, 4'a des fils hélicoidaux. Ces parois peuvent se déformer élastiquement vers l'extérieur Lors de L'introduction d'une tige filetée dans l'orifice 2' de la semelle et du tube 5, qui est ici taraudé. Au moment de la mise en place de l'élément, les parois 8a, 8b, 8c, 8d agissent comme un poinçon qui guide l'élément Vendant le vissage tout en écartant progressivement sans arrachement le matériau de l'axe 3. IL se produit une compression de ce dernier par les parois 8 à 8d qui en augmente la densité au centre et crée des forces complémentaires de retenue de L'élément sur Les parois 8a à 8d. Ces forces sont augmentées lors de la pénétration dela vis au delà de l'orifice 2', qui déforme vers l'extérieur lesdites parois. Furthermore, it can be seen in these figures that the tubular part 5 is extended by four thin walls 8a, 8b, 8c, 8d which converge by their tapered end on the axis 3 at a point 9 located beyond the end 4a , 4 'has helical wires. These walls can deform elastically outward during the introduction of a threaded rod into the orifice 2 'of the sole and of the tube 5, which is here tapped. When the element is put in place, the walls 8a, 8b, 8c, 8d act as a punch which guides the element Selling the screwing while progressively moving the material away from the axis 3 without pulling out. IT occurs compression of the latter by the walls 8 to 8d which increases the density in the center and creates additional forces for retaining the element on the walls 8a to 8d. These forces are increased during penetration of the screw beyond the orifice 2 ', which deforms said walls outwards.
On notera enfin que la semelle 1 présente une fente 10 ouverte sur sa face opposée à celle portant les fils 4, 4', pour permettre son vissage au moyen d'un outil d'entraînement. Finally, note that the sole 1 has a slot 10 open on its face opposite to that carrying the wires 4, 4 ', to allow it to be screwed by means of a drive tool.
L'invention trouve une application intéressante dans le domaine des accessoires de fixation. The invention finds an interesting application in the field of fixing accessories.
Elle n'est pas limitée aux modes de réalisation décrits ci-dessus et comprend notamment une variante dans laquelle l'orifice 2, 2' serait remplacé par un téton fileté faisant saillie de la semelle 1 à l'opposé des fils 4, 4' pour recevoir, par exemple, un collier o o u r v j 4'une embase de fixation tubulaire taraudée. It is not limited to the embodiments described above and includes in particular a variant in which the orifice 2, 2 'would be replaced by a threaded stud projecting from the sole 1 opposite the wires 4, 4' to receive, for example, a collar oourvj 4 'a threaded tubular fixing base.
Dans une autre variante, on peut prévoir une pLuralité de fils hélicoidaux, régulièrement répartis autour de l'axe de la partie tubulaire. In another variant, provision may be made for a plurality of helical wires, regularly distributed around the axis of the tubular part.
