PRECAST FLOOR SLAB SYSTEM AND BRIDGE STRUCTURE
PROBLEM TO BE SOLVED: To provide a precast floor slab system in which peeling at a boundary surface between a precast floor slab and a filling member is suppressed.SOLUTION: A precast floor slab system 21 comprises: a pair of precast floor slabs 22 that are formed in a tabular shape and are arranged side by side in a direction intersecting the thickness direction Z; a first rod-like member 23A protruding from a side surface 22aA that is part of one precast floor slab 22A of the pair of precast floor slabs and faces the other precast floor slab 22B, toward the other precast floor slab; and a filling member 24 that is filled between the pair of precast floor slabs in a state in which the filling member covers the first rod-like member and is bonded to each of the pair of precast floor slabs, the filling member transmitting the bending moment between the pair of precast floor slabs to integrate the pair of precast floor slabs. Tensile strength of the filling member is equal to or larger than tensile strength of the pair of precast floor slabs.SELECTED DRAWING: Figure 3
【課題】プレキャスト床版と充填部材との界面で剥離するのを抑え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２１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２２と、一対のプレキャスト床版のうち、一方のプレキャスト床版２２Ａにおける他方のプレキャスト床版２２Ｂに対向する側面２２ａＡから他方のプレキャスト床版に向かって突出する第１棒状部材２３Ａと、一対のプレキャスト床版の間に第１棒状部材を覆った状態で充填されるとともに一対のプレキャスト床版にそれぞれ付着され、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充填部材２４と、を備え、充填部材の引張強度は、一対のプレキャスト床版の引張強度以上である。【選択図】図３
