OPENING STRUCTURE OF REINFORCED CONCRETE SKELETON, REINFORCING MEMBER AND CONSTRUCTION METHOD FOR REINFORCED CONCRETE SKELETON
To provide a construction technology of an opening structure of a reinforced concrete skeleton capable of reducing the amount of material required for construction by reducing the scale of construction.SOLUTION: An opening structure of a reinforced concrete skeleton comprises: an opening 5 formed by removing reinforcing bars 3 of an existing reinforced concrete skeleton 2 and a part of a concrete 4; a reinforcing member 6 inserted into the opening part 5 and provided along the inner periphery of the opening part 5; a cutout part 11 extending from the edge part on the front side in the inserting direction of the reinforcing member 6 toward the rear side; and a joint part 12 for joining the reinforcing member 6 and the reinforcing bar 3 arranged in the cutout part 11, where the reinforcing bar 3 projected from an inner periphery of an opening part 5 is arranged in the cutout part 11.SELECTED DRAWING: Figure 3
【課題】工事の規模を縮小して工事に必要な物量を抑えることができる鉄筋コンクリート躯体の開口構造の施工技術を提供する。【解決手段】既設の鉄筋コンクリート躯体２の鉄筋３およびコンクリート４の一部を除去して形成された開口部５と、開口部５に挿入され、開口部５の内周に沿って設けられた補強部材６と、補強部材６の挿入方向の先頭側の縁部から後尾側に向かって延びる切欠部１１と、開口部５の内周から突出された鉄筋３が切欠部１１に配置され、補強部材６と切欠部１１に配置された鉄筋３とを接合する接合部１２とを備える。【選択図】 図３
