PRECAST FLOOR SLAB SYSTEM, BRIDGE STRUCTURE, PRECAST FLOOR SLAB SYSTEM DESIGN METHOD, AND BRIDGE STRUCTURE MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To provide a precast floor slab system being easily constructed from precast floor slabs and improving fatigue durability while preventing the precast floor slab thickness from increasing.SOLUTION: A precast floor slab system 2 comprises: a pair of precast floor slabs 20, which are formed into tabular shape and disposed in an arrangement direction that intersects a thickness direction Z; and a connection part 25, which is disposed between and attached to the pair of precast floor slabs and integrates the pair of precast floor slabs by transmitting bending moment between the pair of precast floor slabs. The elastic modulus of the connection part is smaller than that of the pair of precast floor slabs and the tensile strength of the connection part is higher than that of the pair of precast floor slabs. The adhesive strength of the connection part to adhere to the pair of precast floor slabs is higher than the tensile strength of the pair of precast floor slabs.SELECTED DRAWING: Figure 2 【課題】プレキャスト床版から容易に構成でき、プレキャスト床版の厚さの増加を抑えつつ疲労耐久性を向上させたプレキャスト床版システムを提供する。【解決手段】プレキャスト床版システム２は、板状に形成され、厚さ方向Ｚに交差する方向に並べて配置された一対のプレキャスト床版２０と、一対のプレキャスト床版の間に設けられるとともに一対のプレキャスト床版に付着され、一対のプレキャスト床版の間で曲げモーメントを伝達することで一対のプレキャスト床版を一体化する接続部２５と、を備え、接続部の弾性率は、一対のプレキャスト床版の弾性率よりも小さく、接続部の引張強度は、一対のプレキャスト床版の引張強度以上であり、接続部が一対のプレキャスト床版に付着する付着強度は、一対のプレキャスト床版の引張強度以上である。【選択図】図２
