Fabricated combined box girder for constructing anti-seismic structure and construction method of fabricated combined box girder
The invention provides a fabricated combined box girder for constructing an anti-seismic structure and a construction method of the fabricated combined box girder, belongs to the technical field of box girder anti-seismic structure construction, and solves the problem that a web plate is prone to cracking when a large load or vibration is applied to a top plate. According to the technical scheme, the box girder comprises a damping support, an inner supporting assembly arranged in the damping support and a top plate arranged on the top of the inner supporting assembly, the damping support comprises a bottom plate and web plates fixedly arranged at the two sides of the top of the bottom plate, and a plurality of evenly-distributed transverse partition plates are arranged on the inner supporting assembly. The fabricated combined box girder has the beneficial effects that stepped inner clamping grooves are formed in the inner sides of the web plates, and the stepped outer clamping blocks are arranged at the two sides of the inner supporting assembly, so that the contact area of the inner supporting assembly and the web plates is increased, a good vibration isolation effect is achieved, and when a large load or vibration is applied to the top plate, the shear strength of the web plates can be enhanced, and therefore, the probability of cracks of the web during vibration is reduced, and the service life of the box girder is prolonged.
本发明提供了一种施工抗震结构的装配式组合箱梁及其施工方法，属于箱梁抗震结构施工技术领域。解决了在顶板施加较大载荷或者震动时腹板容易出现裂痕的问题。其技术方案为：包括减震支座、设置在减震支座内部的内支撑组件以及设置在内支撑组件顶部的顶板，减震支座包括底板和固定设置于底板顶部两侧的腹板，内支撑组件上设置有若干个均匀分布的横隔板。本发明的有益效果为：本发明通过在腹板内侧设置阶梯状的内卡槽，内支撑组件两侧设置阶梯状的外卡块，增加了内支撑组件与腹板的接触面积，起到很好的隔振效果，在顶板施加较大载荷或者震动时，可以加强腹板的抗剪切强度，从而减小腹板在震动时出现裂痕的几率，延长箱梁的使用寿命。
