Abstract
The invention comprises an improved rebar coupler designed to simplify joining rebar while minimizing slippage. It features a male and female threaded external housing, an internal cylinder, springs, and tightening members with wedges. The coupler creates an opposing force to lock rebar securely, addressing challenges in existing methods. Available in two-piece and three-piece configurations, it accommodates various rebar sizes without modification. The design allows for single-person operation, reduces manual labor, and enhances structural integrity. The rebar coupler meets stringent standards like CalTrans CT670, offering advantages over existing products by eliminating heavy equipment needs and complex installation procedures.
