Fully-assembled modular bridge expansion device and mounting method thereof
The invention relates to the technical field of bridge expansion devices, in particular to a full-assembly modular bridge expansion device and a mounting method thereof. An elastic element in sliding fit with the supporting cross beam is fixedly arranged on the lower portion of the displacement box of the full-assembly modular bridge expansion device, the supporting cross beam is erected on the top of the elastic element, and a displacement control assembly is fixedly arranged between the bottom of the edge beam and the supporting cross beam. And the middle beam and the supporting cross beam, the displacement box top cover plate and the boundary beam and the box body are connected through anchor bolts respectively. According to the full-assembly modular bridge expansion device, all parts are broken up into parts, and the parts are assembled into a whole in a factory-like mode. Once the parts of the expansion device are damaged, the parts can be detached and replaced by new parts in time, overall replacement after anchoring area concrete chiseling is not needed any more, the maintenance speed is increased, the maintenance operation time is shortened, the influence on bridge deck traffic is reduced, and the whole-life economic index of the expansion device is better.
本发明涉及桥梁伸缩装置技术领域，尤其涉及一种全组装模数式桥梁伸缩装置及其安装方法。全组装模数式桥梁伸缩装置位移箱下部固定设置与支撑横梁滑动贴合的弹性元件，支撑横梁架设在弹性元件顶部，边梁底部与支撑横梁之间固定设置有位移控制组件；中梁与支撑横梁、位移箱顶部盖板与边梁和箱体均分别通过锚固螺栓连接。全组装模数式桥梁伸缩装置将其所有零部件全部化整为零，并通过工厂化集零为整组装而成。一旦伸缩装置零部件出现损坏，可及时进行拆除更换新件，而不再需要凿除锚固区混凝土后整体更换，养护维修速度提升，维护作业时间缩短，降低对桥面交通的影响，伸缩装置的全寿命期经济指标更好。
