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
