BEAM REINFORCEMENT METAL FITTING AND BEAM REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a beam reinforcement metal fitting and the like that efficiently reinforces a beam.SOLUTION: A beam reinforcement metal fitting 1 has a welded surface 3, a surface 5 facing a flange, a contacting surface 9, a protrusion 7, etc. The beam reinforcement metal fitting 1 is a metallic member made of steel, for example. The beam reinforcement metal fitting 1 is not of a plate-form, but has a three-dimensional form. More specifically, a shape of a cross-section thereof in a longitudinal direction changes from an end toward a central part. The cross-section (cross-section area) of the central part of the beam reinforcement metal fitting 1 in the longitudinal direction is larger than the cross-section (cross-section area) at both ends. By enlarging the cross-section area near the central part of the beam reinforcement metal fitting 1, bending strength may be secured for a portion that bears a largest stress when the beam reinforcement metal fitting 1 is fixed on a beam.
【課題】 効率よく梁を補強することが可能な梁補強金具等を提供する。【解決手段】 梁補強金具１は、溶接面３、フランジ部対向面５、接触面９、突起７等を有する。梁補強金具１は、例えば鋼などの金属製の部材である。梁補強金具１は板状ではなく、３次元的な立体形状を有する。より具体的には、長手方向の端部から中央部に掛けて、断面形状が変化する。梁補強金具１の長手方向の中央部の断面（断面積）は、両端部の断面（断面積）よりも大きい。梁補強金具１の中央部近傍の断面積を大きくすることで、梁補強金具１を梁に固定した際に、最も大きな応力を受け持つ部位の曲げ耐力を確保することができる。【選択図】図４
