BEAM PENETRATION HOLE REINFORCEMENT STRUCTURE
To provide, in a beam penetration hole reinforcement structure having an unreinforced part in a perimeter of a penetration hole, further reliable reinforcement of the penetration hole as well as to improve constructability.SOLUTION: A reinforcement structure 1 for a penetration hole 14 provided in a steel beam 10 having a web 11 and flanges 12, 13, is provided with reinforcements 20a, 20b which include a hole perimeter reinforcement part 21 having an arc edge 22 shaped along a part of a perimeter of the penetration hole 14 and a fastening part 23 which is a fastening point with the web 11, and an unreinforced part 30 provided along a remainder of the perimeter of the penetration hole 14. The hole perimeter reinforcement part 21 is present between the unreinforced part 30 and the flanges 12, 13, and at least one fastening part 23 is provided in each of a plurality of first regions R1 provided in the hole perimeter reinforcement part 21, as well as at least one fastening part is provided in each of second regions R2.SELECTED DRAWING: Figure 1
【課題】貫通孔の周囲に無補強部を有する梁貫通孔補強構造において、貫通孔の補強をより確実に行い、かつ、施工性を改善する。【解決手段】ウェブ１１とフランジ１２、１３を有する鉄骨梁１０に設けられた貫通孔１４の補強構造１において、貫通孔１４の周縁の一部に沿った形状の円弧辺２２を有する孔周補強部２１と、ウェブ１１との締結箇所である締結部２３と、を備えた補強材２０ａ、２０ｂと、貫通孔１４の周縁の残部に沿って設けられた無補強部３０と、を設け、無補強部３０とフランジ１２、１３との間には、孔周補強部２１が存在し、締結部２３を孔周補強部２１に複数設けられた第一領域Ｒ1の各々の領域内に少なくとも一つ設け、かつ、第二領域Ｒ2の各々の領域内に少なくとも一つ設ける。【選択図】図１
