REINFORCEMENT DEVICE FOR EXISTING STEEL FRAME STRUCTURE
PROBLEM TO BE SOLVED: To provide a reinforcement device capable of easily and securely reinforcing a parallel type angle steel assembly constituting an existing steel frame structure without processing the parallel type angle steel assembly at all by using minimum materials.SOLUTION: A steel frame structure 10 is constituted using a parallel type angle steel assembly 20 constituted by combining first and second angle steel materials 21, 22 such that one-edge sides thereof are arranged closely in parallel with each other, and fastened tightly with first to fourth fastening bolts and nuts 51-53 provided at three peripheral places of first to sixth fixing metal fittings 42-47 arranged to be coupled with one another while surrounding a periphery of the parallel type angle steel assembly 20 to make fastening force moving toward the axis of the parallel type angle steel assembly 20 act on the first to sixth fixing metal fittings 42-47, thereby uniting a first reinforcement plate material 31 and the first angle steel material 21, and a second reinforcement plate material and the second angle steel material 22 together.SELECTED DRAWING: Figure 3
【課題】既存の鉄骨構造物を構成するパラレル型山形鋼集成体に何らの加工を施すことなく、かつ最小限の材料を利用してパラレル型山形鋼集成体を容易かつ確実に補強することができる補強装置を提供する。【解決手段】第１及び第２山形鋼材２１、２２を、その一方の辺同士が互いに近接して平行に配列されるように組合わせてなるパラレル型山形鋼集成体２０を用いて鉄骨構造物１０を構成し、パラレル型山形鋼集成体２０の周囲を取り巻くように互いに連結されるように配置された第１乃至第６の固定金具４２〜４７の周方向の三箇所に設けられた第１〜第４の締め付け用ボルト・ナット５１〜５３で締め付けることにより、第１乃至第６の固定金具４２〜４７に対しパラレル型山形鋼集成体２０の軸心に向け移動する締め付け力を作用させて第１補強板材３１と第１山形鋼材２１及び第２補強板材と第２山形鋼材２２を一体化する構成にした。【選択図】 図３
