초록 ▼

Each half of a bifurcated circumferential clamp includes a pair of spaced apart internally oriented semicircular ridges for engaging grooves formed at the end of abutting pipes. Teeth extending adjacent the ridges penetrate the groove walls to physically lock the clamp with the pipes. A circular gas

대표청구항 ▼

A pipe clamp for drawing the ends of a pair of aligned pipes toward one another and for joining them with one another, each of the pipes including an annular groove having an annular base and opposed radially oriented side walls formed proximate the end of the pipe and extending inwardly from the surface of the pipe, said pipe clamp comprising in combination: (a) a first clamp half for encircling approximately one half of the joined pipes and extending across the junction therebetween; (b) a second clamp half for encircling approximately the other half of the joined pipes and extending across the junction therebetween; (c) means for securing said first and second clamp halves to one another and about the joined pipe ends; (d) a pair of arcuate ridges formed in axially opposed halves of each of said first and second clamp halves extending radially inwardly therefrom for engaging the grooves in the respective pipe ends, each of said ridges including a extending radially with respect to the longitudinal axis of the respective clamp half facing inwardly toward the axial center of the respective clamp half and an annular shoulder extending perpendicularly from said inwardly facing side wall; and (e) teeth means extending from each of said ridges for penetrably engaging simultaneously one of the side walls of the groove in the pipe and the surface of the pipe adjacent the engaged side wall, each of said teeth means including an apex extending from said side wall of said ridge to said adjacent annular shoulder extending from said ridge inwardly toward the axial center of the respective clamp half, each of said teeth means having a triangular cross section in a plane transverse to said apex; whereby, upon penetration of said apex simultaneously into the side wall of the pipe groove and the surface of the pipe, each of said teeth means urges the engaged pipe axially toward the junction of the pair of pipes and simultaneously exerts a radial inward force upon the engaged pipe commensurate with securing said first and second clamp having to one another and about the joined pipe ends.
