STEEL BEAM REINFORCEMENT METAL FITTING AND STEEL BEAM REINFORCEMENT STRUCTURE
To provide a steel beam reinforcement metal fitting and a steel beam reinforcement structure using the same, capable of improving work efficiency of positioning and welding and reducing work costs.SOLUTION: A steel beam reinforcement metal fitting 24 for reinforcing a steel beam 6 on which a through hole 6b passing through a web part 6a in the thickness direction is formed comprises a body part 26 formed in an annular shape having the approximately same center axis as that of the through hole 6b, the body part having a center hole 26b passing through in its axial direction and having a diameter smaller than that of the through hole 6b. On one end surface in the axial direction of the body part 26 is formed a contact end surface 26c in approximately parallel with a side surface of the web part 6a of the steel beam 6, the contact end surface having an outer shape formed so as to be larger than a cross-sectional shape of the through hole 6b. On the contact end surface 26c is formed a protrusion 28 protruding in the axial direction. The protrusion has an outer peripheral surface having a cross-sectional shape that is formed so as to be the approximately same as the cross-sectional shape of the through hole 6b in the vicinity of the contact end surface 26c and is formed so as to be smaller than the cross-sectional shape of the through hole 6b at an end on the opposite side to the contact end surface 26c in the axial direction.SELECTED DRAWING: Figure 1
【課題】位置決めや溶接の作業効率を向上させ、作業コストを低減することができる鉄骨梁補強金具、及びこれを用いた鉄骨梁補強構造を提供する。【解決手段】ウェブ部６ａを厚さ方向に貫通する貫通孔６ｂが形成された鉄骨梁６を補強する鉄骨梁補強金具２４であって、貫通孔６ｂと略同一の中心軸を有する環状に形成された本体部２６を備え、その軸線方向に貫通する、貫通孔６ｂより小さな径の中心孔２６ｂが形成され、本体部２６の軸線方向の一方の端面には、鉄骨梁６のウェブ部６ａの側面と略平行な接触端面２６ｃが形成され、その外形は貫通孔６ｂの断面形状より大きく形成され、接触端面２６ｃには軸線方向に突出する突出部２８が形成され、その外周面の断面形状は、接触端面２６ｃの近傍では貫通孔６ｂの断面形状と略同一に形成されると共に、軸線方向の接触端面２６ｃと反対側の端部においては貫通孔６ｂの断面形状より小さく形成された。【選択図】図１
