OPENING REINFORCEMENT UNIT
PROBLEM TO BE SOLVED: To provide an opening reinforcement unit of an underfloor inspection opening capable of surely reinforcing the underfloor inspection opening, and capable of easily executing installation-removal work.SOLUTION: In an opening reinforcement unit 1, an upward opening box-shaped reinforcement frame body is constituted of a reinforcement frame plate 2, a shear reinforcement front plate 3 and a back plate 4 detachably installed on its front face and a back face. A buckling preventive horizontal member 8 is extended in a detachable state on the inside of the box-shaped reinforcement frame body so that a strut state can be formed between left-right side plate parts 22 and 23. Bearing force reduction in a continuous footing caused by chipping of a reinforcement and concrete in an inspection opening part can be compensated by rigidity of the box-shaped reinforcement frame body for installing the horizontal member 8.SELECTED DRAWING: Figure 2
【課題】床下点検用開口の補強を確実に行うことができ、取り付け・取り外し作業を簡単に行うことができる床下点検用開口の開口補強ユニットを提供すること。【解決手段】開口補強ユニット１では、補強用枠板２と、その前面および背面に着脱可能に取り付けたせん断補強用の前面板３、背面板４とによって、上方に開口する箱型補強枠体が構成される。箱型補強枠体の内部には左右の側板部分２２、２３の間に突っ張り状態を形成できるように座屈防止用の横架部材８が着脱可能な状態で架け渡される。横架部材８が取り付けられた箱型補強枠体の剛性によって、点検用開口部分における鉄筋やコンクリートの欠損に起因する布基礎の耐力低下を補うことができる。【選択図】図２
