High-position girder falling method for steel box girder incremental launching construction
The invention discloses a steel box girder incremental launching construction high-position girder falling method which comprises a plurality of sections of flange plate columns supported by a longitudinal distribution girder, and the supporting height of a preset target is adjusted by increasing or decreasing the number of the sections of flange plate columns in the height direction; the pushing bearing beam, the front supporting bearing beam and the rear supporting bearing beam are adjusted to the preset height through the corresponding flange plate column sets. A base of the jack is arranged at the top of a flange plate column group for supporting the pushing bearing beam, and a lifting end of the jack supports the pushing bearing beam; a plurality of bearing beam cushion blocks are further included, and the height of the cushion layer is adjusted by increasing or decreasing the bearing beam cushion blocks in the height direction. The superposition height of the x cushion beam cushion blocks is consistent with the height of one section of flange plate column; safety and controllability in the beam falling process can be achieved, the stability of the linear shape of the steel box beam is guaranteed, it is guaranteed that beam falling is in place at a time, and the good effect in beam falling control is achieved.
本发明公开了一种钢箱梁顶推施工高位落梁方法，包括被纵向分配梁支撑的法兰盘柱，所述法兰盘柱为若干节，若干节所述法兰盘柱通过在高度方向的增加或减少调节对预设目标的支撑高度；所述顶推垫梁、前支撑垫梁和后支撑垫梁分别通过各自对应的法兰盘柱组调节至预设高度；所述千斤顶的底座设置于将顶推垫梁支撑的法兰盘柱组顶部，所述千斤顶的升降端将顶推垫梁支撑；还包括垫梁垫块，所述垫梁垫块为若干块，若干块所述垫梁垫块通过在高度方向的增加或减少调节垫层高度；x块垫梁垫块的叠加高度与一节法兰盘柱高度一致；能够实现落梁过程中的安全可控，保证了钢箱梁线形的稳定，保证落梁后一次到位，达到了落梁控制中的良好效果。
