Method for forming floor

Abstract

【課題】スラブ厚みの増加を抑えながら、上下階の遮音性能の向上を図る。 【解決手段】板本体3Aの長手方向両端面に開口する貫通穴3Bが板本体3Aの幅方向に間隔をあけて並列状態となるように成形してある穴あきプレキャストコンクリート板3の複数を、梁2間に並列に架設して、穴あきプレキャストコンクリート板3の上にコンクリート4を打設して一体の床版1を構築する床形成方法において、穴あきプレキャストコンクリート板3の複数枚の内の少なくとも一部に対して、貫通穴3Bの長手方向での中間部にセメント系充填材Gを充填する。 【選択図】図1
PROBLEM TO BE SOLVED: To enhance sound insulation performance on upper and lower stories while suppressing an increase in thickness of a slab. SOLUTION: In this method for forming a floor, a plurality of perforated precast concrete plates 3, which are molded in such a manner that through-holes 3B opened in both the longitudinal end surfaces of a plate body 3A are brought into a juxtaposed state at intervals in the width direction of the plate body 3A, are erected in parallel between beams 2; and concrete 4 is placed on the perforated precast concrete plates 3 so as to construct an integrated floor slab 1. Longitudinal intermediate portions of the through-holes 3B of at least some of the plurality of precast perforated concrete plates 3 are filled with a cement-based filler G.
