Precast concrete member joining sleeve holding structure

摘要

PROBLEM TO BE SOLVED: To simultaneously project the whole sleeves, while holding the sleeve in a state of being stored in a cavity formed in one PC member, when joining a pair of PC members opposed in the axial direction by using the sleeve of straddling between reinforcements buried in respective ones.SOLUTION: A sleeve 3 is movably arranged in the axial direction in a cavity 1c of one PC member 1, and an energization member 4 for energizing the sleeve 3 to the other PC member 2 side is arranged between the innermost side end surface in the cavity 1c and an end surface 3a of the sleeve 3 opposed to this. A locking object member 5 is rotatably connected around a support shaft parallel to the material axis of the PC member 1 to an end surface 1b of the one PC member 1, and a state of storing the sleeve 3 in the cavity 1c is maintained by locking an end surface 3b on the other PC member 2-side of the sleeve 3 on the locking object member 5, and a tension material 6 for rotating the locking object member 5 around a support shaft is connected to the locking object member 5.SELECTED DRAWING: Figure 1
