Cast-in-place box girder cantilever support and mounting method thereof
The invention discloses a cast-in-place box girder cantilever support and a mounting method thereof. The cast-in-place box girder cantilever support comprises a support body, a bearing beam, verticallength-adjustable supporting pieces, an oblique length-adjustable supporting piece and a tripod. A first jacking is mounted at the upper part of the support body; the bearing beam is mounted at the upper part of the first jacking; a first distribution beam and a second distribution beam are mounted at the upper part of the bearing beam; the vertical length-adjustable supporting pieces are respectively mounted at the upper parts of the first distribution beam and the second distribution beam; transverse connecting rods are installed between the vertical length-adjustable supporting pieces, theoblique length-adjustable supporting piece is installed on the side portion of the second distribution beam, the tripod is installed on the upper portion of the bearing beam, and the side portion of the tripod is connected with the side, deviating from the first distribution beam, of the second distribution beam. The problems that in the prior art, when a cantilever support bears large lateral force, instability is likely to happen, economy is poor, and the side web formwork supporting stability is poor are solved.
本申请公开了一种现浇箱梁悬臂支架及其安装方法。所述现浇箱梁悬臂支架包括支架本体、承重梁、竖向长度可调支撑件、斜向长度可调支撑件和三脚架，支架本体的上部安装有第一顶托，承重梁安装于第一顶托的上部，承重梁的上部安装有第一分配梁和第二分配梁，竖向长度可调支撑件分别安装于第一分配梁和第二分配梁的上部，竖向长度可调支撑件之间安装有横向连接杆，斜向长度可调支撑件安装于第二分配梁的侧部，三脚架安装于承重梁的上部，三脚架的侧部与第二分配梁背离第一分配梁的一侧相连。本申请解决现有技术中，悬臂支架受较大侧向力时容易失稳、经济性差以及边腹板模板支撑稳定性差的问题。
