ELEVATED RIGID FRAME BRIDGE AND ELEVATED RIGID FRAME BRIDGE CONSTRUCTION METHOD
To provide an elevated rigid frame bridge and elevated rigid frame bridge construction method that is easy to construct and has excellent durability.SOLUTION: In an elevated rigid frame bridge 100 having a plurality of columns 1 arranged in a prescribed direction and a vertical beam 2 joined on the plurality of columns, at least one of the columns arranged in the prescribed direction (bridge axis direction) has a gate-shaped column constructed with a pair of column members 10 erected across a vertical beam and a cross beam 20 joined on the pair of column members. The vertical beam is joined on the cross beam of the gate-shaped column. As an example, when the vertical beams are joined to the cross beam, if the cross beam and the vertical beams are joined by a joint formed by placing concrete on the upper surface of the cross beam, a large-scale support scaffolding will not be required and the construction period can be shortened. Thus allowing an elevated rigid frame bridge to be constructed with good workability.SELECTED DRAWING: Figure 1
【課題】施工し易く耐久性に優れたラーメン高架橋及びラーメン高架橋の構築方法を提供する。【解決手段】所定方向に配列された複数の柱１と、その複数の柱上に接合された縦梁２とを有しているラーメン高架橋１００における、所定方向（橋軸方向）に配列された複数の柱のうちの少なくとも１つは、縦梁を挟む配置に立設された一対の柱材１０と、その一対の柱材上に接合された横梁２０とを備えて構成された門型の柱であり、縦梁は門型の柱の横梁上に接合されている。例えば、横梁上に縦梁を接合するにあたり、横梁の上面にコンクリートを打設して形成した接合部によって横梁と縦梁を接合するようにすれば、大掛かりな支保工足場が不要となって工期を短縮することができるので、施工性よくラーメン高架橋を構築することができる。【選択図】図１
