Overall closure construction device and method for side-span steel beams of oversized-span cable-stayed bridge
The invention provides an oversized span cable-stayed bridge side span steel beam integral closure construction device and method, and belongs to the technical field of side span closure construction.The oversized span cable-stayed bridge side span steel beam integral closure construction device comprises a crane frame assembly and two ground lifting hook supporting assemblies, and the two sides of the lower portion of the crane frame assembly are connected with lifting hook assemblies correspondingly. The overall height is adjusted according to the height of a bottom steel beam by placing a plurality of ground lifting hook supporting assemblies on the surfaces of the bridge bodies at the two ends, the lifting hook assemblies penetrate through the bottom from a circular sliding block and hook a bridge assembly through the two lifting hook assemblies, and the surfaces of the bridge bodies at the two ends are spliced by a circle along a bridge floor through splicing fixing frames to be fixed; the bottommost portion and the bottom of the bridge assembly are placed at the bottom of the bridge assembly through a bottom-holding cylinder and a telescopic connecting hook lock, the telescopic connecting hook lock is connected to the surface of the splicing fixing frame to support the bottom of the bridge assembly in a bottom-holding mode, and the situation that after an upper device loosens a hook by mistake, the bridge assembly can fall off immediately to cause accidents is avoided.
本发明提供一种超大跨径斜拉桥边跨钢梁整体合龙施工装置及方法，属于边跨合龙施工技术领域，包括吊机架组件和两个地面吊钩支撑组件，所述吊机架组件的下方两侧分别连接有吊钩组件。本发明通过设置在两端桥体的表面放置多个地面吊钩支撑组件根据底部钢梁的高度来调整整体高度，并且将吊钩组件从圆形滑块贯穿到底部利用两个吊钩组件勾住桥梁组件，在两端桥体的表面利用拼接固定架沿着桥面拼接一圈固定，在最底部与桥梁组件的底部利用兜底圆柱和可伸缩连接钩锁放置在桥梁组件的底部，可伸缩连接钩锁连接在拼接固定架的表面为桥梁组件的底部做以兜底的支撑形式，放置上部装置失误松钩后桥梁组件会立刻掉落而照成意外。
