PRECAST CONCRETE FLOOR SLAB AND JOINING METHOD

To provide a precast concrete floor slab and a joining method capable of efficiently performing joining work and enhancing safety.SOLUTION: A precast concrete floor slab according to one embodiment is a precast concrete floor slab 1 extending in a bridge axis direction D1 and a bridge axis perpendicular direction D2, and comprising: a pair of wall balustrades 20; a pair of ground covering parts 30 positioned below the pair of wall balustrades 20; and a floor slab part 10 extending in the bridge axis perpendicular direction D2 between the pair of ground covering parts 30. The pair of wall balustrades 20, the pair of ground covering parts 30, and the floor slab part 10 are integrated in advance. A recess 23 is formed in one of a pair of end faces 21 and 22 of each wall balustrade 20 facing the bridge axis direction D1. A protrusion 24 to be inserted into the recess 23 is formed on the other of the pair of end faces 21 and 22 of each wall balustrade 20 facing the bridge axis direction D1.SELECTED DRAWING: Figure 3 【課題】接合作業を効率よく行うことができると共に、安全性を高めることができるプレキャストコンクリート床版及び接合方法を提供する。【解決手段】一実施形態に係るプレキャストコンクリート床版は、橋軸方向Ｄ１及び橋軸直角方向Ｄ２に延びるプレキャストコンクリート床版１であって、一対の壁高欄部２０と、一対の壁高欄部２０のそれぞれの下部に位置する一対の地覆部３０と、一対の地覆部３０の間において橋軸直角方向Ｄ２に延びる床版部１０と、を備え、一対の壁高欄部２０、一対の地覆部３０、及び床版部１０は、予め一体化されており、橋軸方向Ｄ１を向く各壁高欄部２０の一対の端面２１,２２のうちの一方には、凹部２３が形成されており、橋軸方向Ｄ１を向く各壁高欄部２０の一対の端面２１，２２のうちの他方には、凹部２３に挿入される突出部２４が形成されている。【選択図】図３
