Unbonded precast prestressed concrete structure and structures with the structure

摘要

PROBLEM TO BE SOLVED: To prevent compression failure in an unbonded PCaPC structure. SOLUTION: An unbonded PCaPC structure is a first unbonded PCaPC pillar body including a first concrete member molded into a columnar shape and a tension material inserted through the first concrete member in an unbonded state and a tension is applied. A first unbonded PCaPC including a second unbonded PCaPC pillar body including a second concrete member molded into a columnar shape and a tension material inserted through the second concrete member in an unbonded state and to which tension is applied. It has a joint formed by arranging one end of the pillar body and one end of the second unbonded PCaPC pillar body in the vertical direction so as to face each other. The peripheral edge of one or both end faces of the member is molded into a curved surface. [Selection diagram] Fig. 1
