Claims

[Scope of Claim for Utility Model Registration] A mortar threaded joint, which is a reinforcing bar joint made up of a sleeve part and a threaded part, coaxially joined together, is embedded in one end of the main reinforcing bar of the member. In the precast concrete member, (a) the open end of the sleeve portion of the joint is located inward from and opens into the end surface of the end portion, and (b) there is a connection between the end surface and the open end of the sleeve portion. An insertion hole that communicates with the sleeve part is provided between them, and (c) an inlet and an outlet, which are through holes provided in the side wall of the sleeve part, are provided in the member so as to open into the side wall of the member. (iv) A precast concrete member characterized by a structure in which the end of the main reinforcing bar of the member is screwed into the threaded portion of the joint.
