CONSTRUCTION METHOD FOR SLAB-LIKE MEMBER
To achieve improvement in workability and shortening of a construction period, in construction of a slab-like member made of half-precast concrete.SOLUTION: A construction method for a slab-like member made of half-precast concrete which comprises a precast slab and cast-in-place concrete and which is mounted striding over a pair of support members includes steps of: mounting width direction end parts of the precast slab on the pair of support members; suspending the precast slab by a timbering stretched above the precast slab via a suspension material extending downward from the timbering; constructing a reinforcement structure above the precast slab; placing and curing cast-in-place concrete at an upper part of the precast slab so as to bury at least part of the suspension material and the reinforcement structure; and separating the suspension material from the timbering and removing the timbering.SELECTED DRAWING: Figure 1
【課題】ハーフプレキャストコンクリート製のスラブ状部材の構築において、作業性の向上や工期の短縮を図る。【解決手段】プレキャストスラブと現場打ちコンクリートからなり、一対の支持部材に跨って搭載されるハーフプレキャストコンクリート製のスラブ状部材の構築方法であって、前記一対の支持部材に前記プレキャストスラブの幅方向端部を搭載する工程と、前記プレキャストスラブの上方に掛け渡した支保工により当該支保工から下方に向かって伸びる吊り下げ材を介して前記プレキャストスラブを吊り下げる工程と、前記プレキャストスラブの上方に鉄筋構造を構築する工程と、前記吊り下げ材の少なくとも一部と前記鉄筋構造を埋設するように前記プレキャストスラブの上部に現場打ちコンクリートを打設し養生する工程と、前記支保工から前記吊り下げ材を分離し、前記支保工を撤去する工程と、を含む。【選択図】図１
