DISPOSITIF DE LIAISON POUR REUNIR BOUT A BOUT DEUX BARRES.CONNECTION DEVICE FOR JOINING END TO END TWO BARS.
La présente addition a pour objet des perfectionnements au The subject of this addition is improvements to the
brevet principal na 90 13404 du 29 octobre 1990. main patent na 90 13404 of October 29, 1990.
Dans le brevet principal le dispositif de liaison bout à bout de deux barres comprenant une douille pour recevoir les deux extrémités des barres est caractérisé en ce qu'il comprend au moins un écrou pouvant se fixer sur la douille et au moins une pièce de butée fixée sur l'extrémité de l'une des barres pour venir en contact avec l'extrémité de l'écrou interne à la In the main patent, the end-to-end connection device of two bars comprising a socket for receiving the two ends of the bars is characterized in that it comprises at least one nut which can be fixed on the socket and at least one fixed stop piece. on the end of one of the bars to come into contact with the end of the internal nut at the
douille.socket.
La solidité de la liaison dépend ainsi de celle de la fixation de l'écrou sur la douille d'une part, et du contact entre la The solidity of the connection thus depends on that of the fixing of the nut on the sleeve on the one hand, and on the contact between the
pièce de butée et l'écrou, d'autre part. stop piece and nut, on the other hand.
Les barres peuvent être filetées et/ou non filetées. The bars can be threaded and / or unthreaded.
Dans l'exemple représenté, dans le brevet principal, les barres sont des barres filetées à pas rapide sur lesquelles sont fixés des manchons cylindriques filetés intérieurement au même pas, constituant des pièces de butée alors que les écrous In the example shown, in the main patent, the bars are threaded bars with rapid pitch on which are fixed cylindrical sleeves internally threaded at the same pitch, constituting stop parts while the nuts
se vissent dans ou sur la douille au pas ISO. are screwed into or onto the socket with ISO pitch.
Dans ce cas, le diamètre externe du manchon est inférieur au diamètre interne de la douille, ce qui permet de réunir deux barres qui ne sont pas alignées Bien entendu, le diamètre de l'alésage central de l'écrou est également supérieur au In this case, the external diameter of the sleeve is less than the internal diameter of the sleeve, which makes it possible to join two bars which are not aligned Of course, the diameter of the central bore of the nut is also greater than the
diamètre externe de l'écrou.external diameter of the nut.
Mais il peut se produire des cas o les axes des barres à réunir forment entre eux un angle de quelques degrés et le -2- dispositif selon le brevet principal ne peut pas rattraper ce However, there may be cases where the axes of the bars to be joined form an angle of a few degrees between them and the device according to the main patent cannot catch up with this.
décalage angulaire.angular offset.
La présente addition a pour objet de pallier cet inconvénient. The purpose of this addition is to overcome this drawback.
Conformément à l'addition, le dispositif selon la revendication 1 du brevet principal est caractérisé en ce que la face arrière d'au moins l'un des manchons est bombée de manière à pouvoir prendre appui sur l'écrou dans une position 1 C angulaire variant de quelques degrés autour de l'axe de l'écrou. Ainsi, la portée des manchons sur la face avant de l'écrou According to the addition, the device according to claim 1 of the main patent is characterized in that the rear face of at least one of the sleeves is curved so as to be able to bear on the nut in an angular 1 C position varying a few degrees around the axis of the nut. Thus, the range of the sleeves on the front face of the nut
n'est plus linéaire mais est plus ou moins sphérique. is no longer linear but is more or less spherical.
Selon une autre caractéristique de l'invention, le corps du manchon est de forme générale tronconique pour permettre un déplacement angulaire maximum à l'intérieur de la douille et According to another characteristic of the invention, the body of the sleeve is of generally frustoconical shape to allow maximum angular displacement inside the socket and
par rapport à l'axe de celle-ci.with respect to the axis thereof.
De préférence, la partie avant de l'écrou recevant la face bombée du manchon est conformée en cuvette pour assurer une meilleure portée sensiblement de type à rotule du manchon Preferably, the front part of the nut receiving the convex face of the sleeve is shaped into a bowl to ensure a better bearing substantially of the ball-joint type of the sleeve.
contre l'écrou.against the nut.
Les deux manchons d'un même dispositif peuvent présenter la The two sleeves of the same device can have the
même structure ou être différents. same structure or be different.
Ainsi, si dans le cas o l'on doit réunir un ensemble de barres d'armatures sur des barres s'étendant sensiblement dans la même direction il est possible en remplaçant un manchon selon le brevet par un manchon selon l'addition de compenser Thus, if in the case where a set of rebar has to be assembled on bars extending substantially in the same direction, it is possible by replacing a sleeve according to the patent with a sleeve according to the addition to compensate
un écart angulaire limité.limited angular deviation.
-3- Il est également possible, selon l'addition, dans le cas d'un manchon cylindrique de prévoir une cavité interne excentrique -3- It is also possible, depending on the addition, in the case of a cylindrical sleeve to provide an eccentric internal cavity
par rapport à l'axe du manchon.relative to the axis of the sleeve.
Cette disposition permet dans certains cas de compenser des This provision allows in certain cases to compensate for
écarts d'alignement plus importants. greater alignment deviations.
Le manchon qui a été cité dans le brevet principal peut dans certains cas être serti à l'extrémité d'une barre filetée ou non Il est également possible de forger en bout de l'une ou des deux barres une protubérance destinée à assurer la fonction du manchon, c'est- à-dire essentiellement le contact The sleeve which was cited in the main patent can in certain cases be crimped at the end of a threaded bar or not It is also possible to forge at the end of one or both bars a protuberance intended to ensure the function the sleeve, i.e. essentially the contact
avec l'écrou.with the nut.
Il est bien entendu possible de réunir ou liaisonner deux It is of course possible to combine or link two
barres dont l'une est filetée et dont l'autre ne l'est pas. bars, one of which is threaded and the other of which is not.
Il va de soi que de nombreuses variantes peuvent être introduites, notamment par substitution de moyens techniquement équivalents sans pour autant sortir du cadre de l'addition. -4- It goes without saying that many variants can be introduced, in particular by replacing technically equivalent means without going beyond the scope of the addition. -4-
