DISPLAY MEMBER FOR FLOOR SLAB CONSTRUCTION AND FLOOR SLAB CONSTRUCTION METHOD
To clearly determine a position where a reinforcement should be cut and accurately install a void at an accurate position when a floor slab having a through hole is constructed, and secure a predetermined covering depth between an inner peripheral surface of the through hole of the floor slab and the reinforcement.SOLUTION: An inner circle 21 and an outer circle 22 are formed on an upper surface 11 of a planar display member 10. The size of the inner circle 21 corresponds to the size of a through hole 2 of a floor slab 1. A radius difference Δr20 between the outer circle 22 and the inner circle 21 corresponds to a covering depth t1a between an inner peripheral surface of the through hole 2 and a reinforcement 3 in the floor slab 1. The display member 10 is arranged at a predetermined position of a form 4 defining a bottom surface of the floor slab 1. After the reinforcement 3 is arranged, the reinforcement 3 crossing the outer circle 22 is cut and removed right above the outer circle 22, and a void 6 is arranged on the inner circle 21 in planar projection view.SELECTED DRAWING: Figure 4
【課題】貫通穴を有する床スラブの施工に際して、鉄筋を切断すべき位置を明確に判断でき、かつボイドを正確な位置に設置でき、ひいては床スラブの貫通穴の内周面と鉄筋との間に所定のかぶり厚さを確保する。【解決手段】面状の表示部材１０の上面１１に内側円２１及び外側円２２を形成する。内側円２１の大きさを床スラブ１の貫通穴２の大きさと対応させる。外側円２２と内側円２１との半径差Δｒ２０を貫通穴２の内周面と床スラブ１内の鉄筋３とのかぶり厚さｔ１ａと対応させる。表示部材１０を、床スラブ１の底面を画成する型枠４の所定位置に配置する。鉄筋３を配筋した後、平面投影視において、外側円２２と交差する鉄筋３を外側円２２の直上において切断して撤去し、内側円２１の上にボイド６を配置する。【選択図】図４
