Description

La présente invention a pour objet un ensemble (E) d'un dispositif de connexion (DC) entre deux corps en béton selon le préambule de la revendication 1.The present invention relates to an assembly (E) of a connection device (DC) between two concrete bodies according to the preamble of claim 1.

On connaît de nombreux dispositifs de connexion entre deux corps en béton.Many connection devices are known between two concrete bodies.

Ainsi par exemple, on connait par le document EP 554483 un dispositif de connexion comportant une plaque de retenue comportant des doigts de clipsage pour la fixation de barres d'une armature métalique. Le clipsage requiert un effort assez important. De plus, ce clipsage n'est possible qu'après fixation de la douille sur la plaque de retenue. Dès lors, si la douille n'est pas préfixée, il est nécessaire de retirer la plaque de retenue de la paroi de coffrage, ceci pour éviter tout déplacement de la plaque de retenue lors du coulissement du support de la douille le long de la plaque de retenue. De plus en cas de fixation erronée de l'armature sur les doigts, le retrait de celle-ci n'est pas aisé et peut entraîner un arrachement de la plaque de retenue par rapport à la paroi de coffrage.So for example, we know from the document EP 554483 a connection device comprising a retaining plate comprising clipping fingers for fixing bars of a metal frame. Clipping requires a fairly significant effort. Moreover, this clipping is only possible after fixing the sleeve on the retaining plate. Therefore, if the sleeve is not pre-fixed, it is necessary to remove the retaining plate from the formwork wall, this to prevent any displacement of the retaining plate when sliding the sleeve support along the plate. restraint. In addition, in the event of incorrect fixing of the reinforcement on the fingers, its removal is not easy and may lead to the retaining plate being torn from the formwork wall.

Par le document EP 773324 , on connaît un dispositif de connexion avec une douille solidaire à une tôle pliée avec une extrémité recourbée. Le remplissage correct de béton entre la douille et la tôle n'est pas aisé. La fixation de l'ensemble douille et tôle pliée à une paroi de coffrage et armature n'est pas facile, en particulier de par le poids total de l'ensemble à fixer.By document EP 773324 , there is known a connection device with a socket integral with a folded sheet with a curved end. The correct filling of concrete between the sleeve and the sheet is not easy. The fixing of the socket and folded sheet assembly to a formwork and reinforcement wall is not easy, in particular due to the total weight of the assembly to be fixed.

Par le document EP1113115 , on connaît un dispositif de connexion comprenant un ensemble formé par une tôle pliée soudée à des barres d'armature et solidaire d'une douille. La fixation de cet ensemble à une paroi n'est pas facile.By document EP1113115 , a connection device is known comprising an assembly formed by a folded sheet welded to reinforcing bars and secured to a socket. Fixing this assembly to a wall is not easy.

L'invention a pour objet un ensemble d'un dispositif de connexion permettant une fixation aisée de l'ensemble à une paroi de coffrage, tout en assurant un positionnement correct de l'armature, ainsi qu'après la prise du béton un excellent maintien de l'armature dans le corps en béton. En cas d'erreur de positionnement, le retrait de l'ensemble est aisé, ce qui favorisera le personnel à corriger l'emplacement des ensembles. Au cas où la douille venait à être endommagée après le positionnement d'un ensemble sur une paroi de coffrage ou au cas de l'utilisation d'une douille non appropriée, l'ensemble permet un remplacement aisé de la douille endommagée ou non appropriée par une autre.The subject of the invention is an assembly of a connection device allowing easy fixing of the assembly to a formwork wall, while ensuring correct positioning of the reinforcement, as well as, after setting the concrete, excellent maintenance. reinforcement in the concrete body. In the event of a positioning error, the assembly can be easily removed, which will encourage personnel to correct the location of the assemblies. In the event that the bushing becomes damaged after positioning an assembly on a formwork wall or in the event of the use of an inappropriate bushing, the assembly allows easy replacement of the damaged or inappropriate bushing by another.

D'autres avantages que procurent l'invention ressortiront de la description.Other advantages afforded by the invention will emerge from the description.

L'invention a pour objet un ensemble ayant les caractéristiques de la revendication 1.The subject of the invention is an assembly having the characteristics of claim 1.

Ceci permet une fixation aisée de la plaque de retenue sur une paroi de coffrage avant la fixation par simple clipsage sur la plaque de retenue, d'une part de la douille de coulissement (2) et de l'armature (3), le clipsage pouvant s'opérer dans un ordre ou dans un autre. Cette fixation par clipsage permet un démontage aisé de l'ensemble, par exemple en cas de positionnement incorrect de la plaque de retenu ou en cas d'une pièce défectueuse.This allows easy fixing of the retaining plate on a formwork wall before fixing by simple clipping on the retaining plate, on the one hand of the sliding sleeve (2) and of the frame (3), the clipping can operate in one order or another. This clip-on fixing allows easy dismantling of the assembly, for example in the event of incorrect positioning of the retaining plate or in the event of a defective part.
