Newly-added support mounting method for additionally arranging steel member in anti-overturning transformation of single-column pier bridge
According to the newly-added support installation method for the additionally-arranged steel member in anti-overturning transformation of the single-column pier bridge, the back pressure device and the newly-added support are arranged between the top face of the additionally-arranged steel member and the beam bottom in advance, a certain numerical value torque is applied to the device, reverse loading of the newly-added support is achieved, the stress state of the support is accurately controlled, and the stability of the newly-added support is improved. And the design requirements are met. The newly-added support installation method is suitable for the scheme that steel members are additionally arranged in the anti-overturning stability transformation of the single-column pier bridge, and pot-type supports or plate-type rubber supports are all suitable for the single-column pier bridge. According to the method, the adverse effect on the stress safety of the main beam structure and the transverse linkage component of the main beam structure caused by asynchronous forced displacement and transverse displacement of synchronous jacking is avoided, the installation construction process of the newly-added support is controllable, the construction procedure is simple, and the economic benefit advantage is obvious.
本发明提供一种独柱墩桥梁抗倾覆改造增设钢构件的新增支座安装方法，通过在增设的钢构件顶面及梁底之间提前布置反压装置和新增支座，并对装置施加一定数值扭矩实现对新增支座的反向加载，精确控制支座受力状态，使其符合设计要求。本发明新增支座安装方法适用于独柱墩桥梁抗倾覆稳定性改造增设钢构件方案，盆式支座或板式橡胶支座均适用。该方法避免了同步顶升强迫位移及横向位移不同步对主梁结构及其横向联系构件受力安全带来的不利影响，新增支座安装施工过程可控且施工工序简单，经济效益优势明显。
