Title (EN) U-BOLT CLAMP ASSEMBLY
(FR) ASSEMBLAGE DE COLLIER DE SERRAGE EN U
Abstract: front page image
(EN)Saddles for U-bolt clamp assemblies used for joining together sections of tubing at a connection, wherein one section of tubing is telescoped within another, have a tendency to twist when a force sufficient to effect the connection is applied to the clamp assembly. To avoid this twisting of the saddle various complicated methods have been used to strengthen the saddle member which often involves welding. The object of the disclosed invention is to provide an uncomplicated strengthened saddle (10) formed from a single sheet metal member (36) which is bent into a configuration that obviates any welding requirements. The member (36) is folded along a line to (52) from a two-layer web portion (24) and a pair of tubular portions (26, 28). Each of the tubular portions (26, 28) receives a leg (18) of a U-shaped bolt (12). Each tubular portion (26, 28) is formed of an inner layer of sheet metal (30) which has substantially a 360 circumferential extent and an outer layer (32) bent around the inner layer (30) and which extends around at least a 180 circumferential extent. The outer layer (32) thus serves to hold the saddle (14) in a folded condition without the use of welds.
(FR)Des pattes d"attache pour des assemblages de bride de serrage en U utilisees pour attacher ensemble des sections de tubes a un raccordement, ou une section de tubes entre dans une autre, ont tendance a se tordre lorsqu"une force suffisante pour effectuer la connexion est appliquee sur l"assemblage de brides de serrage. Pour eviter cette torsion de la patte d"attache differentes methodes compliquees ont ete utilisees pour renforcer la patte d"attache et consistent souvent a souder. Une patte d"attache renforcee simple (10) est formee a partir d"une seule feuille metallique (36) qui est pliee avec une configuration qui evite toute soudure. La plaque metallique (36) est pliee suivant une ligne (52) en une partie a deux couches (24) et en une paire de parties tubulaires (26, 28). Chacune des parties tubulaires (26, 28) recoit une jambe (18) d"un etrier en U (12). Chaque partie tubulaire (26, 28) est formee d"une couche interne de feuilles metalliques (30) ayant une circonference de 360 et une couche externe (32) repliee autour de la couche interne (30) et qui se prolonge circonferentiellement a 180 au moins. La couche externe (32) sert ainsi a maintenir la patte d"attache (14) dans un etat plie sans utiliser des soudures.
