Description

Dispositif permettant l'accrochage d'éléments en sousface d'un plancher constitué de poutrelles en béton
La présente invention a pour objet un dispositif destiné à permettre l'accrochage de divers bléments tels que faux-plafond, rails de supports de plaques, supports d'éclairage, canalisations etc... en sous face d'un plancher constitué de poutrelles en béton
Il est connu de réaliser des planchers en disposant parallèleleinrit les unes aux autres des poutrelles en béton dont le profil est analogue & celui d'un T inversé puis en disposant entre lesdites poutrelles des entrevous qui reposent sur les ailes de ces poutrelles, ce après quoi on coule une chape de béton sur cet assemblage.Device allowing the attachment of elements beneath a floor made of concrete joists
The present invention relates to a device intended to allow the attachment of various elements such as false ceilings, support rails for plates, lighting supports, pipes, etc. on the underside of a floor made of beams in concrete
It is known to make floors by placing parallel to each other concrete beams whose profile is similar to that of an inverted T then by placing between said beams interjoists which rest on the wings of these beams, after which a concrete screed is poured on this assembly.

Il est également connu que l'on ne peut pas employer les moyens usuels de perçage pour mettre en place des fixations dans la face inférieure des poutrelles (par exemple par le procédé appelé "Spitage") parce que l'on risque d'endommager les fils d'acier ou de faire éclater la sous-face. It is also known that it is not possible to use the usual drilling means to set up fasteners in the underside of the beams (for example by the process called "Spitage") because there is a risk of damaging the steel wire or popping the underside.

Lorsque les entrevous sont en céramique ou en béton, on peut placer les fixations en question dans ces entrevous. Nais lorsque les entrevous sont en polystyrène, cela n'est pas possible parce que le polystyrène n'a aucune tenue mécanique. En outre, lorsque l'on veut suspendre des éléments lourds, comme par exemple des canalisations, il est préférable d'en faire supporter le poids par les poutrelles elles-memes qui sont les plus porteuses, ce qui jusqu'à présent n'est pas possible. When the interjoists are ceramic or concrete, the fixings in question can be placed in these interjoists. Born when the interjoists are made of polystyrene, this is not possible because the polystyrene has no mechanical strength. In addition, when you want to suspend heavy elements, such as pipes, it is preferable to have the weight supported by the beams themselves which are the most load-bearing, which until now has not been Not possible.

La présente invention a pour objet d'apporter une solution à ce problème en permettant de suspendre les divers éléments sus-mentionnés aux poutrelles. The object of the present invention is to provide a solution to this problem by making it possible to suspend the various elements mentioned above from the beams.

La présente invention concerne un dispositif d'accrochage constitué par une pièce de jonction comportant deux suspentes de suspension, symetriques, ladite pièce de jonction supportant au moins une pièce de liaison 8 laquelle est fixe l'élément a suspendre les deux suspentes de suspension étant placées sur la pièce de jonction symétriquement par rapport au centre de la pièce de jonction. The present invention relates to a hooking device constituted by a junction piece comprising two symmetrical suspension lines, said junction piece supporting at least one connecting piece 8 which is fixed the element to be suspended, the two suspension lines being placed on the connecting piece symmetrically with respect to the center of the connecting piece.

De préférence, la ou les pièces de liaison sont également placées symétriquement par rapport au centre de la pièce de jonction. Preferably, the connecting piece or pieces are also placed symmetrically with respect to the center of the connecting piece.

De préférence également, les crochets de suspension sont disposés de façon à être l'un et l'autre contenus dans le plan vertical médian de la pièce de jonction. Also preferably, the suspension hooks are arranged so as to be both contained in the median vertical plane of the connecting piece.

A titre d'exemples non limitatifs et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés

Figures 9 to 12 four alternative embodiments of the connecting piece.

En se reportant å ces figures, on voit que le dispositif selon l'invention est constitué par une pièce de jonction 1 comportant deux suspentes de suspension 2 et 3. Dans cet exemple, la pièce de jonction 1 est un parallélépipède en bois et les suspentes 2 et 3 comportent une partie centrale 2a, 3a verticale ; une partie inférieure, horizontale, filetée 2b, 3b traversant la pièce de jonction 1 pour y être fixée par deux écrous ; une partie supérieure 2c, 3c constituant les suspentes proprement dites, qui viennent faire prise sur les épaulement ou ailes 4a et 4b du talon de la poutrelle 4 en béton précontraint. Referring to these figures, it can be seen that the device according to the invention consists of a connecting piece 1 comprising two suspension lines 2 and 3. In this example, the connecting piece 1 is a wooden parallelepiped and the lines 2 and 3 have a vertical central part 2a, 3a; a lower, horizontal, threaded part 2b, 3b passing through the junction piece 1 so as to be fixed there by two nuts; an upper part 2c, 3c constituting the lines proper, which come to grip on the shoulder or wings 4a and 4b of the heel of the beam 4 in prestressed concrete.

Sur les figures 1 a 3, la pièce de jonction comporte un évidement 5 qui traverse de part en part la pièce de jonction 1. Cet évidement 5 est placé au centre de symétrie de la pièce de jonction 1. In FIGS. 1 to 3, the junction piece has a recess 5 which passes right through the junction piece 1. This recess 5 is placed at the center of symmetry of the junction piece 1.

Les deux parties 2b et 3b de fixation des suspentes 2 et 3 sont disposées symétriquement par rapport à l'évidement 5 et donc par rapport au centre de symétrie de la pièce de jonction. Ceci a pour effet que le plan géométrique contenant les parties verticales 2a et 3a des suspentes passe par ledit centre de symétrie. The two parts 2b and 3b for fixing the lines 2 and 3 are arranged symmetrically with respect to the recess 5 and therefore with respect to the center of symmetry of the junction piece. This has the effect that the geometric plane containing the vertical parts 2a and 3a of the lines passes through said center of symmetry.

Il est cependant préférable que ce plan géométrique soit confondu avec le plan vertical médian. However, it is preferable that this geometrical plane be confused with the median vertical plane.

de la pièce de jonction 1. Dans ce but, comme cela est représenté à la figure 3 les parties inférieures des parties centrales 2a et 3a sont légèrement coudées.of the connecting piece 1. For this purpose, as shown in FIG. 3, the lower parts of the central parts 2a and 3a are slightly bent.

Ainsi, l'évidement 5 des parties centrales des suspentes et les parties supérieures 2c, 3c faisant prise sur les rebords 4a et 4b de la poutrelle 4 sont dans un même plan perpendiculaire à la pièce de jonction et à la poutrelle 4.Thus, the recess 5 of the central parts of the lines and the upper parts 2c, 3c engaging on the edges 4a and 4b of the beam 4 are in the same plane perpendicular to the junction piece and to the beam 4.

Sur la figure 4, on voit que dans l'évidement 5 on peut mettre une tige filetée 6 au bout de laquelle est placé un sabot 7 qui est enfilé dans les rainures d'un profilé 8. Ce profilé 8 peut servir à la fixation d'un faux plafond ou analogue. In Figure 4, we see that in the recess 5 we can put a threaded rod 6 at the end of which is placed a shoe 7 which is threaded in the grooves of a profile 8. This profile 8 can be used for fixing d 'a false ceiling or the like.

La figure 5 représente une variante selon laquelle une patte 9 est clouée (ou vissée) å l'extrémité de la pièce de jonction, l'extrémité inférieure de cette patte 9 étant découpée pour recevoir les rebords du profilé 8. FIG. 5 represents a variant according to which a tab 9 is nailed (or screwed) at the end of the junction piece, the lower end of this tab 9 being cut out to receive the edges of the profile 8.

Sur les figures 7 et 8, on voit que la tige filetée 6 peut supporter soit une rampe éclairage le, soit un collier 11 pour une canalisation 12. In FIGS. 7 and 8, it can be seen that the threaded rod 6 can support either a lighting ramp 1c or a collar 11 for a pipe 12.

La figure 6 est une variante de la figure 4 selon laquelle la tige 6 est suffisamment longue pour permettre au moyen de deux ecrous de bloquer le dispositif par appui contre la face inférieure du talon de la poutre 4. FIG. 6 is a variant of FIG. 4 according to which the rod 6 is long enough to allow by means of two nuts to block the device by pressing against the underside of the heel of the beam 4.

La figure 9 représente une première variante de réalisation de la pièce 1. Selon cette variante, elle est constituée par un profilé en U inverse, la partie centrale comportant un orifice 13, correspondant é l'évidement 5, et les deux ailes latérales comportant deux paires d'orifices 14 et 15 correspondant aux perçages de la pince 1 des figures 1 à 3, recevant les parties inférieures de fixation 2b et 3b des suspentes 2 et 3. FIG. 9 represents a first alternative embodiment of the part 1. According to this alternative, it is constituted by an inverted U-shaped profile, the central part comprising an orifice 13, corresponding to the recess 5, and the two lateral wings comprising two pairs of holes 14 and 15 corresponding to the holes in the clamp 1 of Figures 1 to 3, receiving the lower fixing parts 2b and 3b of the lines 2 and 3.

La figure ie représente une variante de réalisation de la figure 9, l'orifice central 13 étant remplacé par une plaque verticale 16. FIG. 1e represents an alternative embodiment of FIG. 9, the central orifice 13 being replaced by a vertical plate 16.

Sur la figure 11, on voit que l'on peut fixer à la pièce de jonction 1 des pattes en équerre 17, la figure 12 représentant une variante de ces pattes.  In FIG. 11, it can be seen that the brackets 17 can be fixed to the junction piece 1, FIG. 12 showing a variant of these lugs.
