Description

L’invention se rattache au secteur technique des éléments de fixation dans le bâtiment et concerne plus particulièrement un piton, dit de suspension.The invention relates to the technical sector of fasteners in the building and relates more particularly to a piton, said suspension.

Ce type de piton est parfaitement connu pour un homme du métier. Pour l’essentiel, ce piton comprend un corps cylindrique constituant une vis à bois pour taraudeuse, généralement de 6 x 60 mm, présentant à l’une de ses extrémités une tête hexagonale, par exemple de 10 mm, avec un taraudage femelle M6, M7 ou M8, destinée à recevoir une tige filetée. Cette tige filetée a une longueur adaptée à la configuration, par exemple d’éléments de poutre en bois, et est destinée à recevoir des éléments d’une ossature, par exemple, pour la fixation d’un faux-plafond.This type of piton is well known to a person skilled in the art. For the most part, this stud comprises a cylindrical body constituting a wood screw for tapping, generally 6 x 60 mm, having at one of its ends a hexagonal head, for example 10 mm, with a female thread M6, M7 or M8, for receiving a threaded rod. This threaded rod has a length adapted to the configuration, for example of wooden beam elements, and is intended to receive elements of a frame, for example, for fixing a false ceiling.

Ce même type de piton existe également dans une configuration, non plus femelle, mais dans une configuration mâle, en ce sens que la tête hexagonale est remplacée par une portée cylindrique filetée pour le vissage de la tige. Une portée hexagonale est formée entre cette portée cylindrique filetée, et la portée de vissage du piton.This same type of bolt also exists in a configuration, no longer female, but in a male configuration, in that the hexagonal head is replaced by a threaded cylindrical bearing for screwing the rod. A hexagonal seat is formed between this threaded cylindrical seat, and the bolt of the bolt.

Quelle que soit sa forme de réalisation, ce type de piton est, le plus souvent, destiné à être fixé sur un support bois, par exemple des poutres.Whatever its embodiment, this type of stud is, in most cases, intended to be fixed on a wooden support, for example beams.

Par contre, pour certaines applications, lorsqu’il est nécessaire de fixer ce piton dans du béton, il convient préalablement de percer dans le béton un trou de diamètre 8 mm pour la mise en place d’une cheville, par exemple métallique, taraudée au moyen d’un outil.On the other hand, for certain applications, when it is necessary to fix this stud in concrete, it is first necessary to drill into the concrete a hole of diameter 8 mm for the establishment of an anchor, for example metal, threaded at means of a tool.

Il résulte donc de cet état de la technique que ce type de piton, réalisé en acier, ne peut pas être vissé directement dans le béton, mais nécessite préalablement la mise en place d’une cheville, ce qui augmente les coûts et les temps de pose. L’invention s’est fixée pour but de remédier à ces inconvénients d’une manière simple, sûre, efficace et rationnelle.It follows therefore from this state of the art that this type of stud, made of steel, can not be screwed directly into the concrete, but requires the prior installation of an ankle, which increases the costs and times of pose. The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.

Le problème que se propose de résoudre l’invention est de pouvoir visser ce type de piton directement dans le béton en supprimant, par conséquent, l’utilisation de chevilles.The problem to be solved by the invention is to screw this type of piton directly into the concrete, thereby eliminating the use of pegs.

Pour résoudre ce problème, il a été conçu un piton du type de ceux comprenant, de manière connue, une portée cylindrique auto-taraudeuse, dont l’une des extrémités présente une tête agencée pour le vissage d’une tige filetée apte à recevoir un élément tel qu’une ossature pour faux plafondTo solve this problem, it was designed a piton of the type comprising, in known manner, a self-tapping cylindrical bearing, one end of which has a head arranged for screwing a threaded rod adapted to receive a element such as false ceiling framing

Selon l’invention, compte tenu du problème posé à résoudre le problème, le piton est soumis à un traitement de dureté du type carbonitruration pour être vissé directement dans du béton sans l’utilisation d’une cheville.According to the invention, given the problem solved to solve the problem, the stud is subjected to a carbonitruration type hardness treatment to be screwed directly into concrete without the use of an ankle.

La longueur de la portée cylindrique est comprise entre 35 et 45 mm et le diamètre de la portée cylindrique correspond à un perçage de 5 mm dans le béton.The length of the cylindrical bearing is between 35 and 45 mm and the diameter of the cylindrical bearing corresponds to a hole of 5 mm in the concrete.

Il résulte de ces caractéristiques que le fait de percer à 5 mm, et non plus à 8 mm, permet de supprimer la cheville, et par conséquent, de travailler plus rapidement, avec moins de fatigue.It follows from these characteristics that the fact of drilling at 5 mm, and no longer at 8 mm, allows to remove the ankle, and therefore to work faster, with less fatigue.

On observe également une diminution significative de la longueur, comprise entre 35 et 45 mm, au lieu de 50 à 60 mm, lorsque le piton est réalisé en acier normal, selon l’état antérieur de la technique.There is also a significant decrease in length, between 35 and 45 mm, instead of 50 to 60 mm, when the piton is made of normal steel, according to the prior art.

Comme indiqué dans l’analyse de l’état antérieur de la technique, le piton peut être du type femelle, ou du type mâle, de sorte que la tête agencée pour le vissage de la tige filetée peut être réalisée selon deux formes de réalisations différentes, à savoir : - soit la tête est du type femelle, en étant constitué par portée hexagonale présentant un taraudage interne pour le vissage de ladite tige, - soit la tête est du type mâle, en étant constituée par une portée cylindrique filetée pour le vissage de ladite tige, une portée hexagonale étant formée entre ladite portée cylindrique filetée et la portée cylindrique auto-taraudeuse. L’invention est exposée ci-après plus en détail à l’aide des figures des dessins annexés dans lesquels : - la figure 1 est une vue de face du piton, selon les caractéristiques de l’invention, dans le cas d’un piton du type femelle, - la figure 2 montre une forme de réalisation du piton du type mâle, - la figure 3 montre, par une vue à caractère schématique, une utilisation donnée à titre d’exemple du piton, dans le cas de la réalisation d’un faux-plafond.As indicated in the analysis of the prior art, the stud may be of the female type, or of the male type, so that the head arranged for screwing the threaded rod can be made according to two different embodiments , ie: - either the head is of the female type, being constituted by hexagonal bearing having an internal thread for screwing said rod, - or the head is of the male type, being constituted by a threaded cylindrical bearing for screwing said rod, a hexagonal bearing being formed between said threaded cylindrical seat and the self-tapping cylindrical seat. The invention is described below in more detail with the help of the figures of the accompanying drawings in which: - Figure 1 is a front view of the peak, according to the features of the invention, in the case of a peak of the female type, FIG. 2 shows an embodiment of the male-type peak, FIG. 3 shows, by a schematic view, a use given by way of example of the pin, in the case of the production of 'a false ceiling.

De manière classique, ce piton, plus communément connu sous le nom de piton de rénovation, comprend une portée cylindrique auto-taraudeuse (1), dont l’une des extrémités présente une tête (2) agencée pour le vissage d’une tige filetée (3). Cette tige (3) est destinée à recevoir un élément (4), tel qu’une ossature pour, par exemple, la fixation d’un faux-plafond (P).Conventionally, this pin, more commonly known as the renovation pin, comprises a self-tapping cylindrical seat (1), one end of which has a head (2) arranged for screwing a threaded rod (3). This rod (3) is intended to receive an element (4), such as a frame for, for example, the fixing of a false ceiling (P).

Toujours de manière connue, la tête (2) peut être du type femelle, en étant constituée par une portée hexagonale (2a) présentant un taraudage interne (2b) pour le vissage de la tige (3), figure 1. Ou bien, comme le montre la figure 2, la tête (2) est du type mâle, en étant constitué par une portée cylindrique filetée (2c), pour le vissage de la tige (3), qui dans ce cas présente une extrémité taraudée. Une portée hexagonale de manœuvre (2d) est formée entre la portée filetée (2c) et la portée auto-taraudeuse (1).Still in known manner, the head (2) may be of the female type, consisting of a hexagonal bearing (2a) having an internal thread (2b) for screwing the rod (3), FIG. 1. Or, as As shown in Figure 2, the head (2) is of the male type, being constituted by a threaded cylindrical bearing surface (2c), for the screwing of the rod (3), which in this case has a threaded end. A hexagonal operating surface (2d) is formed between the threaded seat (2c) and the self-tapping seat (1).

Selon une caractéristique à la base de l’invention, le piton, tel que défini, et ce, quelle que soit sa forme de réalisation, c’est-à-dire, du type femelle, figure 1, ou du type mâle, figure 2, est soumis à un traitement de dureté, du type carbonitruration.According to a characteristic underlying the invention, the peak, as defined, and this, whatever its embodiment, that is to say, of the female type, Figure 1, or the male type, figure 2, is subjected to a hardness treatment of the carbonitriding type.

Il en résulte que le piton peut être vissé directement dans le béton, sans l’utilisation d’une cheville, comme rappelé dans l’analyse de l’état antérieur de la technique.As a result, the stud can be screwed directly into the concrete, without the use of an ankle, as recalled in the analysis of the prior art.

Par ailleurs, la longueur de la portée cylindrique auto-taraudeuse (1) peut être diminuée d’une manière significative, en étant désormais comprise entre 35 et 45 mm, et non plus de 60 mm, selon l’état antérieur de la technique.Furthermore, the length of the self-tapping cylindrical surface (1) can be reduced significantly, now being between 35 and 45 mm, and no longer than 60 mm, according to the prior art.

De même, le diamètre de la portée cylindrique auto-taraudeuse permet de faire un perçage de 5 mm dans le béton. Or, le fait de percer à 5 mm et non plus à 8 mm, permet de supprimer, comme indiqué, l’utilisation d’une cheville.In the same way, the diameter of the self-tapping cylindrical surface makes it possible to drill 5 mm in the concrete. However, the fact of drilling at 5 mm and no longer at 8 mm, allows to remove, as indicated, the use of ankle.

On renvoie à la figure 3, qui montre, à titre schématique, l’utilisation d’un piton, selon les caractéristiques de l’invention, fixé directement dans le béton (B), et dans le cadre d’une application à la réalisation d’un faux-plafond (P).Referring to Figure 3, which shows, schematically, the use of a peak, according to the features of the invention, fixed directly in the concrete (B), and in the context of an application to the realization a false ceiling (P).

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la suppression de l’utilisation d’une cheville, dans le cas où le piton de rénovation doit être fixé dans le béton.The advantages are apparent from the description, in particular it is emphasized and recall the removal of the use of an ankle, in the case where the piton renovation must be fixed in the concrete.

On observe également que la diminution de la longueur du piton, n’altère pas ses caractéristiques techniques, en considérant le traitement de carbonitruration auquel est soumis ledit piton.It is also observed that the decrease in piton length does not alter its technical characteristics, considering the carbonitriding treatment to which said piton is subjected.
