摘要： A high strength grouted pipe coupler (1, 30) by which either a pair of spaced, axially aligned steel reinforcement bars (i.e. rebars 3 and 5) are reliably spliced to one another or a single reinforcement bar (32) is spliced to a flat steel plate (34) to form a T-headed bar configuration. The reinforcement bars (3, 5, 32) are surrounded by a spiral reinforcing spring (12, 44) within a hollow cylindrical sleeve or tube (10, 36). The coupler tube (10, 36) is filled with an epoxy or cement based grout (22) within which the reinforcement bars and the reinforcing spring (12, 44) are embedded. Set screws (20, 46) are moved through the coupler tube (10, 36) to maintain the position of the reinforcement bars (3, 5, 32) prior to the coupler tube being filled with epoxy or cement. The pipe coupler (1, 30) herein disclosed has application for connecting together contiguous columns, walls, beams and similar structures to enable buildings, parking garages, bridges, subways and airports to be better able to survive a seismic event.
