REINFORCEMENT STRUCTURE AND REINFORCEMENT UNIT FOR REINFORCED CONCRETE FOUNDATION BEAM
PROBLEM TO BE SOLVED: To provide a reinforcement structure and a reinforcement unit for a reinforced concrete foundation beam having a human passage opening and capable of suppressing an increase in a beam height.SOLUTION: A reinforcement structure (12) of the present invention for a reinforced concrete foundation beam (10) having a circular opening (22) includes at least one frame unit (26) installed inside the foundation beam to surround the opening. The unit includes a pair of first reinforcing members (28) made of an angle steel and extending in a longitudinal direction of the foundation beam (10) at above and below the opening, and at least a pair of second reinforcing members (30, 32) disposed on both sides of the opening (22) along the longitudinal direction of the foundation beam. The second reinforcing members comprise a belt-like flat steel bar or reinforcing bar fixed on the pair of first reinforcing members.
【課題】人通口を有する鉄筋コンクリート造基礎梁の補強構造であって梁せいの増大を抑えることを可能とする補強構造及び補強用ユニットを提供すること。【解決手段】本発明は、円形の貫通孔（２２）が設けられた鉄筋コンクリート造の基礎梁（１０）の補強構造（１２）に係る。補強構造は、基礎梁の内部に配置され貫通孔の周囲を取り巻く少なくとも１つのフレーム状のユニット（２６）を含む。ユニットは、貫通孔の上方及び下方をそれぞれ基礎梁（１０）の長手方向へ伸びる、山形鋼からなる一対の第１の補強部材（２８）と、基礎梁の長手方向に関して、貫通孔（２２）の両側にそれぞれ位置する少なくとも一対の第２の補強部材（３０、３２）とを備える。第２の補強部材は、一対の第１の補強部材に固定された帯状の平鋼又は鉄筋からなる。【選択図】図１
