发明名称 HIGH STRENGTH GROUTED PIPE COUPLER
摘要 A high strength grouted pipe coupler by which either a pair of spaced, axially aligned steel reinforcement bars (i.e. rebars) are reliably spliced to one another or a single reinforcement bar is spliced to a flat steel plate to form a T-headed bar configuration. The reinforcement bars are surrounded by a spiral reinforcing spring within a hollow cylindrical sleeve or tube. The coupler tube is filled with an epoxy or cement based grout within which the reinforcement bars and the reinforcing spring are embedded. Set screws are moved through the coupler tube to maintain the position of the reinforcement bars prior to the coupler tube being filled with epoxy or cement. The pipe coupler 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.
