To provide a construction passage with which the material costs are low, and which is easy to construct.SOLUTION: Each opposing main girder 3 of a construction passage 1A includes an upper piece 3a, a lower piece 3b, and a connection part 3c between the upper piece and the lower piece. The upper piece 3a protrudes in a horizontal direction to the opposing main girder side. The lower piece 3b protrudes in parallel with the upper piece 3a. The connecting part 3c, the upper piece 3a, and the lower piece 3b form a U-shaped cross section. A bolt head engaging groove 11 opened on the opposite side to the opposing main girder is formed in the longitudinal direction in the connecting part 3c. A transverse beam 5 has an L-shaped cross section with a horizontal piece 5a and a vertical piece 5b. The horizontal piece 5a is mounted across the pair of lower pieces 3b, 3b of the main girder. A brace 9 has an L-shaped horizontal cross section. An L-shaped one side piece 9a has a bolt shaft insertion hole 9c. A shaft 20b of a bolt 20 having a head 20a engaged with the bolt head engaging groove 11 of the main girder 3 is inserted into the bolt shaft insertion hole 9c and fixed with a nut 21.SELECTED DRAWING: Figure 1
【課題】材料コストが安価であり、施工し易い架設通路を提供する。【解決手段】本発明にかかる架設通路１Ａにおいて、対向する各主桁３は、上片３ａと、下片３ｂと、上片と下片との連結部３ｃを有し、上片３ａは対向する主桁側へ水平方向に突出しており、下片３ｂは上片３ａと並行に突出しており、連結部３ｃと上片３ａと下片３ｂとで断面コ字形状を形成しており、連結部３ｃには対向する主桁と反対側に開口したボルト頭係合溝１１が長手方向に形成してあり、横梁５は、水平片５ａと垂直片５ｂとで断面Ｌ字形状を成してあり、水平片５ａを一対の主桁の下片３ｂ、３ｂ間に架け渡して取り付けてあり、支柱９は、水平断面がＬ字形状を成しており、Ｌ字の一側片９ａにボルト軸挿通孔９ｃを有し、主桁３のボルト頭係合溝１１に頭２０ａを係合したボルト２０の軸２０ｂをボルト軸挿通孔９ｃに挿通してナット２１で固定してある。【選択図】図１
