OPENING REINFORCEMENT STRUCTURE OF REINFORCEMENT CONCRETE SLAB, AND OPENING REINFORCEMENT
To provide an opening reinforcement structure of a reinforcement concrete slab capable of improving reinforcement arrangement workability compared with conventional ones.SOLUTION: An opening reinforcement structure of a reinforcement concrete slab RCS includes a surrounding reinforcement 4 surrounding an opening of a reinforcement concrete slab RCS (that corresponds to a sleeve 3). The surrounding reinforcement 4 is formed to be an octagon shape in plan view, and is disposed so that a pair of vertical side portions 4a,4b is arranged in parallel to a main reinforcement 1 of the reinforcement concrete slab RCS and a pair of lateral side portions 4c,4d is arranged in parallel to a distributing bar 2 of the reinforcement concrete slab RCS.SELECTED DRAWING: Figure 1
【課題】従来に比べて配筋作業性を向上させることのできる鉄筋コンクリートスラブの開口部補強構造を提供する。【解決手段】鉄筋コンクリートスラブＲＣＳの開口部補強構造は、鉄筋コンクリートスラブＲＣＳの開口部（スリーブ３に相当）を囲繞する囲繞補強筋４を含み、囲繞補強筋４は、平面視で八角形状に形成され、その一対の縦辺部４ａ、４ｂが鉄筋コンクリートスラブＲＣＳの主筋１に平行となり、かつ、その一対の横辺部４ｃ、４ｄが鉄筋コンクリートスラブＲＣＳの配力筋２に平行となるように設置される。【選択図】図１
