Cast-in-place support for 0 # block of concrete beam of cable-stayed bridge and construction method
The cable-stayed bridge concrete beam 0 # block cast-in-place support comprises a bracket base, a bracket frame, a beam frame and a pre-pressing frame, the bracket base is connected with a main tower through an embedded part, one side of the bracket frame is connected with the bracket base, the beam frame is installed on the upper portion of the bracket frame, a plurality of lifting ropes are connected to the beam frame, and the ends, away from the beam frame, of the lifting ropes extend to the ground; the pre-pressing frame is connected with the ends, away from the beam frame, of the lifting ropes, a buoyancy piece is installed at the bottom of the pre-pressing frame, and a gap is reserved between the buoyancy piece and the bearing platform. During construction, the pool is adopted to provide buoyancy for the buoyancy piece, so that the pre-pressing material can be pre-loaded on the pre-pressing frame at a time, then the pre-pressing frame and the pre-pressing material are hoisted into the pool together, and loading and unloading of loads are controlled by controlling the water level of the pool. The device has the effects that the loading material can be conveniently hoisted, and the loading and unloading load can be conveniently controlled.
本申请公开了一种斜拉桥混凝土梁0#块现浇支架，其包括牛腿座、牛腿架、梁架和预压框，牛腿座通过预埋件连接主塔，牛腿架的一侧连接牛腿座，梁架安装于牛腿架的上部，梁架上连接有多根吊绳，吊绳远离梁架的一端延伸到地面，预压框连接吊绳远离梁架的一端，预压框的底部安装有浮力件，浮力件与承台之间留有间隙；施工时，采用水池对浮力件提供浮力，使得预压材料能够预先一次性堆载到预压框上，再将预压框连通预压材料一起吊运到水池中，再通过控制水池的水位来控制加载和卸载载荷。本申请具有便于加载材料吊运以及便于控制加载和卸载载荷的效果。
