Abstract (en)
[origin: WO9810211A1] A joint restraint (10) for securing a first pipe (12) to a second pipe. The joint restraint (10) includes an annular body (14) and a plurality of wedge housings (18) extending from the annular body (14) and characterized by open rear faces (38) to allow coreless casting. A bolt (32) is disposed within a hole (30) in each wedge housing (18) and a wedge (40) is disposed within each wedge housing (18). Each wedge (40) has a bolt-actuated tooth (52), a larger pressure-actuated tooth (54), a top surface (44) having a groove (48) adapted to slidably receive a bolt actuator (32), and a bottom surface (42) that is partially tapered to act as a bearing (76) limiting the extent of bolt-driven actuation.
