JOINT STRUCTURE AND JOINING METHOD
To provide a joint structure and a joining method for a precast floor slab which makes it possible to apply a sufficient tensioning force and also reduce a friction force of tendon so as to improve workability.SOLUTION: Each of a first precast floor slab 10 and a second precast floor slab 20 has end faces 11b, 21b extending in the bridge axial right angle direction D2 and height direction, and insertion holes 11f, 21f extending in a curved manner along the bridge axial right angle direction D2 and into which a tendon 30 is inserted. The end face 11b, 21b and the insertion holes 11f, 21f have irregularities 11c, 21c, 2 extending along the bridge axis right angle direction D2 when viewed from the height direction. When viewed from the height direction, concave portions 11h, 21h of the irregularity 2 of the insertion holes 11f, 21f are formed at the positions of convex portions 11e, 21e of the irregularities 11c, 21c of the end faces 11b, 21b.SELECTED DRAWING: Figure 1
【課題】緊張力を十分に付与することができると共に、緊張材の摩擦力を低減して作業性を向上させることができるプレキャスト床版の接合構造及び接合方法を提供する。【解決手段】第１のプレキャスト床版１０及び第２のプレキャスト床版２０は、共に、橋軸直角方向Ｄ２及び高さ方向に延びる端面１１ｂ，２１ｂと、橋軸直角方向Ｄ２に沿って曲線状に延びる緊張材３０が挿通される挿通孔１１ｆ，２１ｆと、を有し、端面１１ｂ，２１ｂ及び挿通孔１１ｆ，２１ｆには、高さ方向から見たときに橋軸直角方向Ｄ２に沿って延びる凹凸１１ｃ，２１ｃ，２が形成されており、高さ方向から見たときに、挿通孔１１ｆ，２１ｆの凹凸２の凹部１１ｈ，２１ｈは、端面１１ｂ，２１ｂの凹凸１１ｃ，２１ｃの凸部１１ｅ，２１ｅの位置に形成される。【選択図】図１
