UNBONDED PRECAST PRE-STRESSED CONCRETE STRUCTURE AND BUILDING WITH THE STRUCTURE
To prevent compression fracture of an unbonded PCaPC structure.SOLUTION: An unbonded PCaPC structure has a joint part that includes a first unbonded PCaPC column body that includes a first concrete member molded in a columnar shape and a tension material inserted into the first concrete member in an unbonded state and applied with tension, and a second unbonded PCaPC column body including a second concrete member molded in a columnar shape and a tension material inserted into the second concrete member in an unbonded state and applied with tension, and has the first unbonded PCaPC column body and the second unbonded PCaPC column body arranged vertically such that one end of the first unbonded PCaPC column body and one end of the second unbonded PCaPC column body face each other. In the joint part, end surfaces of one or both of the first concrete member and the second concrete member have peripheral edge parts shaped into curved surfaces.SELECTED DRAWING: Figure 1
【課題】アンボンドＰＣａＰＣ構造体において圧縮破壊を防止することを目的とする。【解決手段】アンボンドＰＣａＰＣ構造体は、柱状に成型された第１のコンクリート部材と第１のコンクリート部材にアンボンド状態で挿通され張力が印加された緊張材とを含む第１のアンボンドＰＣａＰＣ柱体と、柱状に成型された第２のコンクリート部材と第２のコンクリート部材にアンボンド状態で挿通され張力が印加された緊張材とを含む第２のアンボンドＰＣａＰＣ柱体と、を含み、第１のアンボンドＰＣａＰＣ柱体の一端と、第２のアンボンドＰＣａＰＣ柱体の一端とが対向するように上下方向に配置されて形成された接合部を有し、接合部において、第１のコンクリート部材及び第２のコンクリート部材の一方又は双方の端面は、周縁部が曲面に成型されている。【選択図】図１
