Synchronous pre-pressing reference section bracket construction device and pre-pressing construction method thereof
The invention discloses a synchronous pre-pressing reference section bracket construction device which comprises a pier column, triangular brackets are symmetrically installed on the two sides of the pier column in the bridge direction, a pressed beam system is arranged on the triangular brackets, counter-force frame inclined supporting rod embedded parts are symmetrically arranged on the two sides of the pier column in the bridge direction, the counter-force frame inclined supporting rod embedded parts are located above the triangular brackets, the outer sides of the counter-force frame inclined supporting rod embedded parts are connected with a counter-force frame inclined supporting rod, and the top end of the counter-force frame inclined supporting rod is fixedly connected with a counter-force frame horizontal rod system. The counter-force frame horizontal rod system is fixedly connected with the pier column in the position over the pier column through finish rolling deformed steel bars anchored in the pier column, a hydraulic jack is further arranged between the pressed beam system and the counter-force frame horizontal rod system, and the counter-force frame horizontal rod system is composed of a plurality of parallel counter-force frame horizontal rods. A pier top embedded steel bar vertical passing seam is reserved between every two adjacent counter-force frame horizontal rods in each group of counter-force frame horizontal rod system.
本发明公开了一种同步预压基准段托架施工装置，包括墩柱，所述墩柱顺桥向两侧对称安装有三角托架，所述三角托架上设置有受压梁系统，所述墩柱的顺桥向两侧对称地设置有反力架斜撑杆预埋件，且所述反力架斜撑杆预埋件位于三角托架的上方，在反力架斜撑杆预埋件的外侧连接有反力架斜撑杆，所述反力架斜撑杆的顶端与反力架水平杆系统固结，反力架水平杆系统在墩柱正上方位置通过锚固于墩柱内的精轧螺纹钢与墩柱相互连接固定，在受压梁系统与反力架水平杆系统之间还设置有液压千斤顶，所述反力架水平杆系统由多根相互平行的反力架水平杆组成，且每组反力架水平杆系统中相邻的两根反力架水平杆之间，都预留有墩顶预埋钢筋竖向通过缝。
