ABSTRACT:
Adjacent precast reinforced concrete modules or members are secured together by a plurality of coupler systems each including a cast metal coupler body embedded in an edge portion of the first concrete member and connected by a coupling member to a reinforcing bar within the first concrete member. The coupler body has an internal cavity with a side opening and an end opening extending to the cavity, and reinforcing wings border the side opening. The second concrete member has another coupling member rigidly connected to an axially aligned reinforcing bar and includes an end portion with a threaded bore. A bolt is inserted into the cavity through the side opening, aligned with the end opening and then threaded into the bore where the bolt is tightened with a wrench extending into the cavity through the side opening. A reusable locating pin may be used to align the concrete members.
