Combined formwork suitable for large-dip-angle arch bridge cantilever pouring and construction method
The invention provides a combined formwork suitable for large-dip-angle arch bridge cantilever casting, which is characterized by comprising a side formwork, a bottom formwork and an inner formwork system, the side formwork and the bottom formwork are mounted on a hanging basket, the inner formwork system comprises a heavy frame and a plurality of inner formworks, a walking system comprises a displacement guide rail and a walking mechanism, the heavy frame is driven by the walking mechanism to move, and the inner formworks are arranged on the side formwork and the bottom formwork. A self-balancing supporting frame is arranged at the front end of the hanging basket, the front end of the displacement guide rail is connected with the self-balancing supporting frame, the rear end of the displacement guide rail is supported by a rail tail support, and a front supporting leg and a rear supporting leg are arranged on the displacement guide rail at intervals. And a laser displacement range finder is arranged on the displacement guide rail. The inner formworks are connected with the heavy frame through the supporting system, real-time distance monitoring is carried out through the laser displacement distance measuring instrument, dynamic adjustment is carried out through the distance adjusting jack, the rail tail support extends to provide supporting for the inner formwork system in the supporting state, and the front supporting legs and the rear supporting legs alternately stretch out and draw back to provide walking supporting for the inner formwork system in the moving state. And the working efficiency is effectively improved.
本发明创造提供了一种适用于大倾角拱桥悬臂浇筑的组合模板，其特征在于：包括侧模板、底模板和内模系统，侧模板和底模板安装于挂篮，内模系统包括承力架和若干内模板，走行系统包括位移导轨和行进机构，由行进机构带动承力架移动，挂篮前端设有自平衡支撑架，位移导轨前端与自平衡支撑架连接，后端由轨尾支架支撑，位移导轨上间隔的设有前、后两支撑腿；位移导轨上设有激光位移测距仪。本发明创造中各内模板通过支撑体系与承力架相连，通过激光位移测距仪进行实时距离监测，通过调距千斤顶进行动态调整，内模系统在支撑状态下由轨尾支架伸长提供支撑，移运状态下前、后支撑腿交替伸缩提供行走支撑，有效提升工作效率。
