PROBLEM TO BE SOLVED: To provide a wire support structure capable of suppressing generation of a recess on an outside surface of a beam even when the length of a wire beam itself increases and a large load is applied to the wire beam according to the increase.SOLUTION: A wire support structure comprises: a pair of columns; a pair of beams 12 arranged at an interval in a vertical direction and bridged between the pair of columns, respectively; and a tie material 16 bridged between the pair of beams. The beam is formed in a cylindrical shape whose cross section orthogonal to a longitudinal direction is a closed cross section. The tie material is joined to the outside surfaces of the beams. Projections 18 projecting radially inward are formed on the inside surfaces of the beams, where the tie material is joined.SELECTED DRAWING: Figure 2
【課題】架線ビーム自体の長さが増大し、それに伴い架線ビームに大きな負荷が加わったとしても、梁の外側面における凹みの発生を抑制することができる架線支持用構造物を提供する。【解決手段】架線支持用構造物は、一対の支柱と、上下方向に間隔をおいて一対に配設され、一対の支柱間にそれぞれ架け渡された梁12と、これら一対の梁間に架け渡された繋ぎ材16と、を備える。梁は、長手方向に直交する断面が閉断面となる筒状に形成されており、梁の外側面に繋ぎ材が接合され、梁における繋ぎ材が接合された箇所の内側面に、径方向内側に向けて突出する凸部18が形成されている。【選択図】図2
