PRECAST FLOOR SLAB INSTALLATION METHOD AND PRECAST FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a precast floor slab installation method and precast floor slab capable of reducing cracking in a filler.SOLUTION: A precast floor slab 20a which forms projected parts 23a on an opposing face 22 which faces a top face 11 on a beam 10 is arranged on the top face 11 of the beam 10 by an arranging process. A filler consisting of a shrinkage-compensating mortar 42, etc., is filled and solidified between the top face 11 of the beam 10 and the opposing face 22 of the precast floor slab 20a on which the projected parts 23a are formed by a filling process. Thereby, cracking of the filler can be reduced as the filler is reinforced by integrating the precast floor slab 20a with the filler using the projecting part 23a.SELECTED DRAWING: Figure 3
【課題】充填材が割れることを低減することができるプレキャスト床版の設置方法及びプレキャスト床版を提供する。【解決手段】配置工程により、桁１０の上面１１と対向する対向面２２に凸部２３ａが形成されたプレキャスト床版２０ａが桁１０の上面１１に配置され、充填工程により、桁１０の上面１１とプレキャスト床版２０ａの凸部２３ａが形成された対向面２２との間に無収縮モルタル４２等の充填材が充填されて固化させられる。凸部２３ａによりプレキャスト床版２０ａと充填材とが一体化されることにより充填材が補強されるため、充填材が割れることを低減することができる。【選択図】図３
