Prefabricated assembled steel bridge deck pavement structure and implementation method thereof
The invention discloses a prefabricated assembled steel bridge deck pavement structure and an implementation method thereof. The prefabricated assembled steel bridge deck pavement structure comprisesa steel panel, positioning profile steel, a prefabricated ECC panel, an FRP grating, shear connectors, shear studs, a cast-in-place ECC section and a wearing layer. The shear-resistant studs are arranged in adjacent corners of the four prefabricated ECC panels. The shear connectors are arranged on the edges of the prefabricated ECC panels, and a cast-in-place ECC section is arranged between everytwo adjacent prefabricated ECC panels. Longitudinal steel bars and transverse steel bars are arranged in the prefabricated ECC panel. And the FRP grid is arranged in the wearing layer at the upper part of the prefabricated ECC panel. The method can be used for bridge deck pavement of medium-span and large-span steel bridges, and the pavement construction of the steel bridge deck can be quickly completed by adopting a prefabricated and assembled construction method. The ECC material is used for replacing a traditional asphalt material, the rigidity of the pavement layer can be improved, and fatigue cracking of the steel panel and damage of the pavement layer are effectively relieved. Due to the arrangement of the shear connectors, the problem of interface slippage of the pavement layer andthe steel panel under the action of various loads can be solved.
本发明公开了一种预制拼装钢桥面铺装结构及其实施方法，该预制拼装铺装结构中包括钢面板、定位型钢、预制ECC面板、FRP格栅、抗剪连接件、抗剪栓钉、现浇ECC段及磨耗层。四块预制ECC面板相邻的角部内设置抗剪栓钉。预制ECC面板边缘设置抗剪连接件，相邻两块预制ECC面板中间设置现浇ECC段。预制ECC面板内部配置纵向钢筋和横向钢筋。FRP格栅设置在预制ECC面板上部的磨耗层中。本发明可用于中、大跨径钢桥的桥面铺装，采用预制拼装的施工方法，可以快速完成钢桥面的铺装施工。使用ECC材料代替传统的沥青材料，可以提高铺装层的刚度，有效缓解钢面板的疲劳开裂和铺装层破损。抗剪连接件的设立，可以解决铺装层与钢面板在各种荷载作用下发生的界面滑移问题。
