Curve-shaped steel shell mounting, positioning and hoisting method
The invention belongs to the technical field of bridge construction, and particularly relates to a curved steel shell mounting, positioning and hoisting method, which comprises the following steps of: 1, preparing for construction, manufacturing and assembling a positioning steel bracket and a first section of steel shell, and finishing acceptance; conducting wire remeasurement and control point encryption work are completed according to conducting wires and benchmarks provided by design, setting-out conditions are met, and all measuring instruments are comprehensively checked and corrected before construction; and the requirements of the distance between two adjacent steel bars and the tensioning force are met. According to the mounting, positioning and hoisting method for the curved steel shell, by arranging the positioning equipment, the mounting table can be fixed to the positioning steel support through relative movement of two limiting frames in the fixing device, the positioning device is driven to move through the deviation device along with descending of the first-section steel shell, and the first-section steel shell is continuously positioned; and then the first-section steel shell is controlled to be accurately placed on the positioning steel support to be in butt joint with the positioning steel support, and the mounting efficiency of the first-section steel shell is improved.
本发明属于桥梁施工技术领域，尤其是一种曲线型钢壳安装定位吊装方法，步骤一、施工准备，对定位钢支架和首段钢壳制造拼装完成，并完成验收；根据设计提供的导线、水准点，完成导线复测、控制点的加密工作，具备放样条件，施工前对所有测量仪器进行全面检查、校正；根据两个相邻钢棒之间的间距及张拉力的要求。该曲线型钢壳安装定位吊装方法，通过设置定位设备，能够通过固定装置内部的两个限位架的相对运动将安装台固定在定位钢支架上，并随着首段钢壳的下降通过偏移装置带动定位装置进行移动，持续对首段钢壳进行定位，进而控制首段钢壳能够准确的放置到定位钢支架上与定位钢支架进行对接，提高了对首段钢壳的安装效率。
