STEEL GIRDER REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a steel girder reinforcement structure which can suitably reinforce steel girders roughly having a H-shape cross section.SOLUTION: A steel girder reinforcement structure 100 comprises a belt-like member 10, which is arranged to bridge a pair of steel girders 1, each of which roughly has a H-shape cross section, and contacts with the bottom face of each lower flange 1b, and one end part 10a of which is connected to an upper flange 1a of one steel girder 1 while the other end part 10b being connected to an upper flange 1a of the other steel girder 1. Tensile force given in the belt-like member 10 reacts in a direction, in which the upper flanges of the pair of steel girders 1 move away from each other. Thus, a swinging movement of webs 1c of the pair of steel girders 1 to tilt to each other of the pair of steel girders was suppressed, enabling reinforcement of the steel girders 1.SELECTED DRAWING: Figure 1
【課題】略Ｈ形断面を有する鋼桁を好適に補強することができる鋼桁補強構造を実現する。【解決手段】対を成して配されている略Ｈ形断面を有する鋼桁１に架け渡すように、それぞれの下フランジ１ｂの下面に接触させた状態に配され、一端部１０ａが一方の鋼桁１の上フランジ１ａに繋がれ、他端部１０ｂが他方の鋼桁１の上フランジ１ａに繋がれている綱状部材１０を備えている鋼桁補強構造１００において、その綱状部材１０に付与されている張力が、対を成す鋼桁１の上フランジ１ａを互いに離間させる方向に作用するので、対を成す鋼桁１のウェブ１ｃが対向する鋼桁１に向けて傾くような首振りを抑制するようにして、鋼桁１を補強することを可能にした。【選択図】図１
