Large cantilever bent cap support and construction method
The invention relates to a large cantilever bent cap support and a construction method, and belongs to the technical field of bridge construction. The two piers are arranged on the bearing platform, the main frame assembly is detachably connected with the piers, the horizontal support is erected at the tops of the piers, and the main frame assembly supports the horizontal support; the top of the horizontal support is detachably connected with an installation platform. The pulley mechanism is installed on the installation platform. The pulley mechanism comprises a first pulley assembly and a second pulley assembly; the first pulley assembly is installed at the end of the installation platform, the second pulley assembly is installed in the middle of the horizontal support, the first pulley assembly and the second pulley assembly are connected through a steel cable, the first pulley assembly changes the downward stress direction of the support cantilever into the upward stress direction, and the second pulley assembly is used for saving the stress of the support cantilever. The bridge pier can be supported from the top of the large cantilever support, use of ground supports is greatly reduced, influence and dependence on ground activities are reduced, and the bridge pier is concentrated in stress and stable in structure.
本发明涉及一种大悬臂盖梁支架及施工方法，属于桥梁施工技术领域，包括桥墩、滑轮机构、水平支架和主架组件；两个桥墩设置在承台，主架组件与桥墩可拆卸连接，水平支架搭设在桥墩的顶部，主架组件支撑水平支架；水平支架顶部可拆卸连接有安装平台，滑轮机构安装在安装平台；滑轮机构包括第一滑轮组件和第二滑轮组件；第一滑轮组件安装在安装平台的端部，第二滑轮组件安装在水平支架的中部，第一滑轮组件和第二滑轮组件通过钢缆连接，第一滑轮组件将支架悬臂的向下的受力方向改变为向上，第二滑轮组件用于节省支架悬臂的受力大小，能从大悬臂支架的顶部支撑，大大减少地面支架的使用，降低对地面活动的影响和依赖，桥墩受力集中，结构稳定。
