REINFORCEMENT METAL FITTING AND REINFORCEMENT STRUCTURE FOR REINFORCED CONCRETE PERFORATED BEAM
To provide a reinforcement metal fitting for reinforced concrete perforated beam capable of exhibiting a higher shear reinforcement effect in the periphery of a through-hole.SOLUTION: A reinforcement metal fitting 10 includes: a frame-like outside reinforcement bar 11 in which an angle formed by a left short side part 111a and a left upper long side part 112a, an angle formed by the left short side part 111a and a left lower long side part 112d, an angle formed by a right short side part 111c and a right upper long side part 112b and an angle formed by the right short side part 111c and a right lower long side part 112c are substantially 135 degrees respectively; a frame-like inside reinforcement bar 12 in which first to fourth side parts 121a-121d are substantially in parallel with the left upper long side part 112a, the right upper long side part 112b, the right lower long side part 112c and the left lower long side part 112d; a first anchoring bar 13 which has anchoring parts (hook parts H) on both ends and in which an intermediate part is joined to the upper part of the outside reinforcement bar 11; and a second anchoring bar 14 which has anchoring parts (hook parts H) on both ends and in which an intermediate part is joined to a lower part of the outside reinforcement bar 11.SELECTED DRAWING: Figure 1
【課題】貫通孔の周囲においてより高いせん断補強効果を発揮することのできる鉄筋コンクリート有孔梁の補強金具を提供する。【解決手段】補強金具１０は、左短辺部１１１ａと左上長辺部１１２ａとがなす角度、左短辺部１１１ａと左下長辺部１１２ｄとがなす角度、右短辺部１１１ｃと右上長辺部１１２ｂとがなす角度及び右短辺部１１１ｃと右下長辺部１１２ｃとがなす角度のそれぞれが略１３５度である枠状の外側補強筋１１と、第１〜第４辺部１２１ａ〜１２１ｄが左上長辺部１１２ａ、右上長辺部１１２ｂ、右下長辺部１１２ｃ、左下長辺部１１２ｄに略平行な枠状の内側補強筋１２と、両端に定着部（フック部Ｈ）を有すると共に中間部が外側補強筋１１の上部に接合された第１定着筋１３と、両端に定着部（フック部Ｈ）を有すると共に中間部が外側補強筋１１の下部に接合された第２定着筋１４と、を含む。【選択図】図１
