REINFORCEMENT DEVICE OF THROUGH HOLE IN STEEL BEAM
PROBLEM TO BE SOLVED: To provide a reinforcement device of through hole in a web of steel beam such as H-steel or I-steel formed with a through hole, capable of reinforcing the web in the outer periphery of the through hole by using a high-strength bolt without using welding while eliminating problems due to welding.SOLUTION: In a steel beam 1 of H-steel or I-steel which has a web 3 formed with a through hole 4, a reinforcing plate 6, which has a communication hole 6a penetrating therethrough and a joint portion 6b in the outer periphery of the communication hole 6a, is positioned on the side face of the web 3 with the communication hole 6a aligned with the through hole 4 of the web 3, and the web 3 and the reinforcing plate 6 are joined using high-strength bolts.SELECTED DRAWING: Figure 2
【課題】Ｈ型鋼又はＩ型鋼からなる鉄骨梁のウェブに貫通穴を形成するものにおいて、この貫通穴の外周部のウェブを補強するとともに、この補強において、溶接を用いることなく、高力ボルトを用い、溶接による問題を解消する。【解決手段】ウェブ３に貫通穴４を形成したＨ型鋼又はＩ型鋼からなる鉄骨梁１において、貫通した連通穴６ａと、該連通穴６ａの外周部に接合部６ｂを有する補強板６を、その連通穴６ａを前記ウェブ３の貫通穴４に位置させて前記ウェブ３の側面に重合し、前記ウェブ３と補強板６とを高力ボルト接合で接合した。【選択図】 図２
