STEEL BEAM REINFORCEMENT STRUCTURE
To be able to reinforce steel beams while keeping costs down.SOLUTION: In a steel beam reinforcement structure in which a reinforcement member 2 is welded and fixed to a web 13 of an existing steel beam 1 on which a through hole 13A is formed, the reinforcement member 2 comprises a closing plate 20 in the form of passing through the through hole 13A from the surface side of the web 13 and closing the through hole 13A from the rear side. The closing plate 20 has a closing portion 21 that is fitted into the through hole 13A and closes the through hole 13A, and a backing plate 22 and a bevel 23 that are integrally formed to enable full penetration welding of the outer circumference portion of the closing portion 21 and a peripheral portion 13B of the through hole of the web 13 from the surface side of the web 13.SELECTED DRAWING: Figure 3
【課題】コストを抑えながら鉄骨梁の補強を図れるようにする。【解決手段】貫通孔１３Ａが形成された既存の鉄骨梁１のウェブ１３に対して補強部材２を溶接固定する鉄骨梁補強構造において、補強部材２は、ウェブ１３の表面側から貫通孔１３Ａを通過して裏面側から貫通孔１３Ａを閉塞する形態の閉塞プレート２０にて構成され、閉塞プレート２０には、貫通孔１３Ａに嵌め込まれて貫通孔１３Ａを閉塞する閉塞部２１と、当該閉塞部２１の外周部分とウェブ１３の貫通孔周縁部１３Ｂとのウェブ１３の表面側からの全周にわたる完全溶け込み溶接を可能にする裏当て金２２と開先部２３とが一体形成されている。【選択図】図３
