Construction device and method for installing arch ribs of steel box basket arch bridge
The invention discloses a construction device and method for installing a steel box basket arch bridge arch rib, and belongs to the technical field of arch bridge arch rib construction. Comprising a hoisting assembly arranged at at least one end of an arch rib, the hoisting assembly comprises symmetrically-arranged arc-shaped rails, arc-shaped sliding ways are arranged on the arc-shaped rails, rotating blocks are arranged on the inner sides of the arc-shaped rails, the outer walls of the rotating blocks are attached to the inner walls of the arc-shaped rails, and containing cavities for containing the ends of the arch rib are formed in the rotating blocks. The outer side of the rotating block is provided with a protruding edge matched with the arc-shaped sliding way in position, the protruding edge is arranged in the arc-shaped sliding way in a sliding mode, the outer wall, located between the arc-shaped rails, of the rotating block is provided with a plurality of protruding teeth, an installation frame is arranged on the outer side face of the arc-shaped sliding way, and a worm matched with the protruding teeth is arranged in the installation frame. According to the technical scheme, the problems that in the prior art, the dip angle of the arch rib is difficult to adjust accurately, arch rib construction is difficult, and construction efficiency is low are solved.
本发明公开了一种安装钢箱提篮拱桥拱肋的施工装置及方法，属于拱桥拱肋施工技术领域。包括在拱肋的至少一端上设置的吊装组件，所述吊装组件包括对称设置的弧形轨道，所述弧形轨道上设有弧形滑道，所述弧形轨道内侧设有转动块，所述转动块的外壁与弧形轨道的内壁贴合，且所述转动块的上设有放置拱肋端部的容纳腔，所述转动块的外侧设有与弧形滑道位置匹配的凸棱，所述凸棱滑动设置于弧形滑道内，所述转动块位于弧形轨道之间的外壁上设有若干凸齿，所述弧形滑道的外侧面上设有安装架，所述安装架内设有于凸齿匹配的蜗杆。本技术方案用以解决现有技术中难以对拱肋的倾角进行精确调节，导致拱肋施工困难和施工效率低下的问题。
