To provide a beam through-hole reinforcing metal fitting that can improve workability more than the conventional one and stably reinforce a beam having a web on which a beam through-hole is formed.SOLUTION: A beam through-hole reinforcing metal fitting 1 comprises: a ring-shaped body part 10 whose both lateral faces 10a and 10b are parallel to each other; a first cylindrical portion 11 that cylindrically protrudes from one lateral face 10a of the body part 10 and has outer diameter OD1 smaller than outer diameter OD0 of the body part 10; and a second cylindrical portion 12 that cylindrically protrudes from the other lateral face 10b of the body part 10 and has outer diameter OD2 smaller than the outer diameter OD0 of the body part. A metal fitting through-hole 13 allowing the beam through-hole reinforcing metal fitting 1 to penetrate in a width direction is formed of an inside space of the body part 10, an inside space of the first cylindrical portion 11 and an inside space of the second cylindrical portion 12. The body part 10 is welded and fixed on one surface of the web in a state where the first cylindrical portion 11 or the second cylindrical portion 12 is inserted in the beam through-hole.SELECTED DRAWING: Figure 1
【課題】従来に比べて施工性を向上させることができ且つウェブに梁貫通孔が形成された梁の補強を安定して行うことのできる梁貫通孔補強金具を提供する。【解決手段】梁貫通孔補強金具１は、両側面１０ａ，１０ｂが平行なリング状の本体部１０と、本体部１０の一方の側面１０ａから円筒状に突出すると共に本体部１０の外径ＯＤ０より小さい外径ＯＤ１を有する第１円筒部１１と、本体部１０の他方の側面１０ｂから円筒状に突出すると共に本体部の外径ＯＤ０より小さい外径ＯＤ２を有する第２円筒部１２と、を有し、本体部１０の内側空間、第１円筒部１１の内側空間及び第２円筒部１２の内側空間によって梁貫通孔補強金具１を幅方向に貫通する金具貫通孔１３が形成され、第１円筒部１１又は第２円筒部１２が前記梁貫通孔に挿入された状態で本体部１０が前記ウェブの片面に溶接固定される。【選択図】図１
