Pre-pressing device for 0 # block bracket of continuous rigid frame bridge and construction method
The invention discloses a pre-pressing device for a 0 # block bracket of a continuous rigid frame bridge and a construction method, and belongs to the technical field of design and construction of bridge engineering structures. According to the pre-pressing device for the 0 # block bracket of the continuous rigid frame bridge and the construction method, the construction period is relatively short, and high-altitude hoisting operation is obviously reduced. The pre-pressing device comprises a bracket or a falsework, the bracket or the falsework is detachably arranged at the corresponding position of the top of the pier column, the pre-pressing device further comprises a back frame system and a pre-pressing loading system, and the back frame system and the bracket or the falsework are arranged at the top of the pier column in the mode that the position of the back frame system is matched with that of the bracket or the falsework. And the bracket or the falsework applies pre-pressure of a specified load through the pre-pressure loading system under the matching of the back frame system.
本发明公开了一种用于连续刚构桥0#块托架的预压装置及施工方法，属于桥梁工程结构物设计建造技术领域。提供一种施工周期相对较短，高空吊装作业明显减少的用于连续刚构桥0#块托架的预压装置及施工方法。所述的预压装置包括托架或膺架，托架或膺架可拆卸的布置在墩柱顶部的相应位置处，所述的预压装置还包括背架系统和预压加载系统，背架系统与托架或膺架位置相适应的布置在墩柱的顶部，托架或膺架通过预压加载系统在背架系统的配合下施加规定载荷的预压力。
