Steel bridge integral synchronous jacking beam falling method
The invention relates to the technical field of building fixing, in particular to a steel bridge integral synchronous jacking beam falling method. The method comprises the following steps: during beamfalling, jacks conduct synchronous jacking, a main beam leaves a beam falling steel support located between the main beam and a bent cap, part of the beam falling steel support is extracted, the jacks return oil, then part of a jacking steel support located below the jacks is extracted, the jacks are placed for repeated jacking, the main beam falls down, and beam falling is completed; and duringjacking, the jacks synchronously jack, the main beam leaves the beam falling steel support, part of the beam falling steel support is inserted, the jacks return oil, part of the jacking steel supportis inserted, the jacks are placed, jacking is repeated, the main beam ascends, and jacking is completed. By the adoption of the steel bridge integral synchronous jacking beam falling method, the problems that in the prior art, accurate positioning control is difficult during beam falling, due to the fact that the tonnage of a beam body is large, lifting and falling of the four corners of the beambody are not synchronous, the beam body is prone to torsional deformation, and safety risks are increased are solved.
本发明涉及建筑固定技术领域，尤其涉及一种钢桥整体同步顶升落梁方法，包括以下步骤：落梁时，千斤顶同步顶升，主梁离开位于主梁与盖梁之间的落梁钢支躲，抽取部分落梁钢支躲，千斤顶回油，然后，抽取部分位于千斤顶下方的顶升钢支躲，再安放千斤顶重复顶升，主梁下落，完成落梁；顶升时，千斤顶同步顶升，主梁离开落梁钢支躲，插入部分落梁钢支躲，千斤顶回油，然后，插入部分顶升钢支躲，再安放千斤顶重复顶升，主梁上升，完成顶升。采用本方案的钢桥整体同步顶升落梁方法，解决了现有技术中落梁时精确定位控制困难，由于梁体吨位大，梁体四角起、落不同步，使得梁体容易扭转变形，安全风险增高的问题。
