<p><P>PROBLEM TO BE SOLVED: To provide a connection structure and a recycle method capable of recycling a precast concrete member. <P>SOLUTION: In a connection structure, cylindrical joints 13 and 23 arranged opposite each other are embedded in respective edge sections of two precast concrete members 10 and 20, and both edge sections of relay reinforcement 40, which passes through a joint space 30 between the precast concrete members 10 and 20, are stored inside the joints 13 and 23. Then, the precast concrete members 10 and 20 are connected each other by filling inside the joints 13 and 23 as well as the joint space 30 with mortar 50 to 52. The connection structure enables the precast concrete members 10 and 20 to be recycled by: separating the two precast concrete members 10 and 20 by cutting the mortar 50 and the relay reinforcement 40 in the joint space; removing the mortar 51 and 52 inside the joints 13 and 23 by water jet; and pulling the cut relay reinforcement 40 out from the joints 13 and 23. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
