Description

Dispositif d'assemblage etanche de tuyaux. Lobjet de 1'invention est un dispositif d'assemblage Manche de tuyaux; il peut eire avantageusement utilise pour assembler des tuyaux en ciment arme. Device for the leaktight assembly of pipes. The object of the invention is a pipe sleeve assembly device; it can be advantageously used to assemble reinforced cement pipes.

11 est caracterise en ce qu'il comporte une gaine @de section libre superieure au diametre exterieur des tuyaux qui seront introduits en elle, ainsi quo des bagues en matiere d6for- mable faisant saillie ä 1'interieur de 1a gaine, se repliant vers 1e milieu de celle-ei lors de 1'introduction des tuyaux et s'ap-pliquant for- tement contre leur surface exterieure, saus 1'action de la Pression du fluide contenu Jans los tuyaux, pour assurer 1',etancheite de 1'as- semblage. 11 is characterized in that it comprises a sheath @ of free section greater than the outside diameter of the pipes which will be introduced into it, as well as rings of deformable material protruding inside the sheath, folding towards the middle of this one during the introduction of the pipes and applying strongly against their outer surface, except the action of the pressure of the fluid contained Jans los pipes, to ensure the tightness of the as - semblance.

Le dessin ,annexe represente, ä titre d'exemples, plusieurs formes d'execution du dispositif. The appended drawing shows, by way of examples, several embodiments of the device.

Los fig. 1 et 2 sont des coupes longitudi- nales d'un.e Premiere forme U'execution avant et apres 1'assemblage des tuyaux; Los fig. 3 et 4 se rapportent ä deux au- tres formes d'execution; La fig. 5 est une coupe longitudinale dune variante de la troisieme forme d'exe- cution; La fig. 6 montre une variante de la pre- miere forme d'exkution. Los fig. 1 and 2 are longitudinal sections of a first form of execution before and after assembly of the pipes; Los fig. 3 and 4 refer to two other embodiments; fig. 5 is a longitudinal section of a variant of the third embodiment; fig. 6 shows a variant of the first form of execution.

Cette Premiere forme d'execution (fig. 1 et 2) comporte une gaine cylindrique a faite par exemple en ciment arme et presentant in Mrieurement deux surfaces cylindriques ex- trAmes de diametre un peu supArieur au dia- metre exterieur des tuyaux A B, ainsi qu'une surface cylindrique mediane ayant un dia- metre notablement plus grand que ce dia- metre exterieur. Aux extremites de la sur- fa.ce mediane sont pratiquees deux rainures circulaires b c oü sont encastrees deux bagues circulaires d e en une matiere defOrmable, elastique ou plastique, en caoutchouc par exemple, faisant saillie ä 1'interieur de la gaine. This first form of execution (fig. 1 and 2) comprises a cylindrical sheath made for example of reinforced cement and presenting two extreme cylindrical surfaces on the inside with a diameter slightly greater than the outside diameter of the pipes A B , as well as a central cylindrical surface having a diameter significantly larger than this outer diameter. At the ends of the median sur- fa.ce are practiced two circular grooves b c where are embedded two circular rings d e in a deformable material, elastic or plastic, rubber for example, protruding inside the sheath.

L'assemblage des deux tuyaux A B se fait en introduisant l'une des .extremites de clha- que tuyau, de chaque cöt6, d.ans la gaine comme 1e montre la fig. 2. Los bagues d et e The two pipes A B are assembled by inserting one of the ends of each pipe, on each side, into the sheath as shown in fig. 2. The rings d and e

sont refoulees et prennent les positions indi duee par rette figlire, s'appliquant contre 1e pourtour des tuyaux A et B. La Pression du fluide contenu Jans les tuyaux applique for tement les bagues de caoutehouc co.ntre la. paroi des tuyaux et assure ainsi 1'etancheite du joint, sann qu'il soit necessaire que les deux tuy aux A et B soient jointifs, un cer tain espace pouvant etre menaA entre eux. are driven back and take the positions indi duee by rette figlire, applying against the first periphery of the pipes A and B. The pressure of the fluid contained Jans the pipes strongly applies the rubber rings co.ntre. wall of the pipes and thus ensures the tightness of the joint, without it being necessary for the two pipes at A and B to be contiguous, a certain space being possible between them.

Danla. seconde forme d'execution (fig. 3) la gaine a a interieurement Sur toute sa Ion ;-ueur 1e meme diametre notablement plus ..rang qu=# 1e diametre exterieur des tuyaus A B, de faqon que les Parties des bagues d e repliees. par Suite de 1'introduction de res tuyaux, trouvent place entre ceux-ei et la -aine. Danla. second form of execution (fig. 3) the sheath has internally Over its entire Ion; -eur the same diameter significantly more .. row that = # 1st outer diameter of the pipes A B, so that the Parts of the rings of folded e. by Following the introduction of res pipes, find place between those and the groin.

La troisieme forme d'execution (fig. 4) presente une saillie interieure mediane f en forme de couronne circulaire continne qui, Tors de 1'assemblage des tuyaux A. B, se place entre res derniers et empeche tont g lissement longitudinal du dispositif. The third form of execution (fig. 4) has a median inner projection f in the form of a continuous circular crown which, when connected to the assembly of the pipes A. B, is placed between the last ones and prevents any longitudinal sliding of the device.

La saillie f peut presenter des interrup tions. The protrusion f may present interruptions.

Si la, gaine a est en ciment arme, an peut obtenir 1e meme resultat en constituant sim plement la. saillie interne au moyen de 1'ar mature metallique g de rette gaine (fig. 5). If sheath a is made of reinforced cement, an can obtain the same result by simply constituting it. internal protrusion by means of the mature metallic ar g of the sheath (fig. 5).

L6 dispositif, au lieu de n'avoir qu'une Beule ba;gue pour cha@clu e tuyau. peut en com porter deux ou plus de deux. Dans ce ras la gaine a (fig. 6) peut presenter interieurement plusieurs surfaces cylindriques de diametre relativement Brand separees par des surfa.ces eylindriques de diametre relativement Petit. Dans les premieres sont pratirlttees les rai nures b L' oü sont encastrees les bagues d faisant saillie ä 1'interieur de la. gaine et se repliant Tors de 1'introduction des tuyaux, comme les traits mixtes 1'indiquent. L6 device, instead of having a Beule ba; gue for cha @ clu e pipe. may comprise two or more. In this flush the sheath a (fig. 6) can present internally several cylindrical surfaces of relatively Brand diameter separated by eylindric surfa.ces of relatively Small diameter. In the first are pratirlttees the grooves b L where are embedded the rings d protruding inside the. sheath and folding Tors of the introduction of the pipes, as the dotted lines 1'indicate.

La raine a peut etre en une mauere autre clue du ciment arme et les bab ies d e d' en une matiere dAformable autre que du caout- chouc. The raincoat may have been made of something else like reinforced cement and the babies d e d' made of a deformable material other than rubber.

Le dispositif peut naturellement servir ä, assembler d'autres tuyaux que des tuyaux en ciment arme. The device can of course be used to assemble pipes other than reinforced cement pipes.
