REINFORCEMENT STRUCTURE FOR REINFORCED CONCRETE FOOTING BEAM
PROBLEM TO BE SOLVED: To improve a reinforcement structure applied to a reinforced concrete footing beam having a circular through-hole.SOLUTION: A reinforcement structure (12) includes beam-type parts (24 and 26) that are provided above and below a circular through-hole (22) of a footing beam (10), respectively. The beam-type parts comprise extension-direction parts (16A and 18A) of a main reinforcement and a plurality of auxiliary main reinforcements (30 and 32), and auxiliary stirrups (38 and 40). The beam-type parts also comprise X-shaped auxiliary main reinforcements (34 and 36) that are arranged in a space surrounded by the auxiliary stirrups.
【課題】円形の貫通孔を有する鉄筋コンクリート造基礎梁に適用される補強構造についてその改善を図ること。【解決手段】補強構造（１２）は、基礎梁（１０）の円形の貫通孔（２２）の上方及び下方にそれぞれ設けられた梁型部（２４、２６）を含む。梁型部は、主筋の伸長方向における一部（１６Ａ、１８Ａ）及び複数の補助主筋（３０、３２）と、補助肋筋（３８、４０）とを備える。梁型部は、さらに、補助肋筋が取り囲む空間に配置されたＸ形補助主筋（３４、３６）を備える。【選択図】図１
