Method for installing small-curve-radius fan-shaped unequal-span cloth span bridge beam plate
The invention relates to a small-curve-radius fan-shaped unequal-span cloth span bridge beam plate installation method, and belongs to the technical field of bridge construction, and the method comprises the following steps: enabling the central axis in the length direction of a main beam of a bridge girder erection machine to be parallel to the longitudinal axis of an N-1 #-N # span beam; the front track is mounted on the N-1 # cover beam, so that the length direction of the front track is parallel to the width direction of the N-1 # cover beam; the middle track is parallel to the front track; the two ends of the beam plate are hoisted to the installation positions of the N-1 # cover beam and the N # cover beam through the 1 # movable winch and the 2 # movable winch correspondingly, and then beam falling is conducted; the embedded steel bars of the end cross beams, the top plates and the middle partition plates of the adjacent beam plates are mutually lapped and firmly welded; the installation method has the effect of improving the installation efficiency and the installation precision of the small-curve-radius fan-shaped unequal-span cloth-span bridge beam plate.
本申请涉及一种小曲线半径扇形不等跨布跨桥梁梁板安装方法，属于桥梁施工技术领域领域，其包括如下步骤：使架桥机主梁长度方向的中轴线与N‑1#‑N#跨梁纵向轴线平行；前轨道安装在N‑1#盖梁上，使前轨道的长度方向与N‑1#盖梁宽度方向平行；使中轨道与前轨道相互平行；1#移动卷扬和2#移动卷扬将梁板的两端分别吊运至N‑1#盖梁和N#盖梁梁板安装处后进行落梁；将相邻梁板的端横梁、顶板、中隔板的预埋钢筋相互搭接焊接牢靠；本申请具有提高小曲线半径扇形不等跨布跨桥梁梁板的安装效率和安装精度的效果。
