Hoisting construction method based on large-span heavy-weight reinforced concrete superposed beam
The invention provides a hoisting construction method based on a large-span heavy-weight reinforced concrete superposed beam, and relates to the technical field of bridge engineering. The device is used for bridge hoisting construction of large-span and heavy-weight steel beams. According to the hoisting sequence of the steel beams, firstly, the steel beams are hoisted according to the full-bridge temperature deformation maximum section and the full-bridge temperature deformation minimum section, and the steel beams can adapt to large-displacement temperature deformation of the girder section and small-displacement temperature deformation of the girder section at first; beam section machining and manufacturing errors can be effectively avoided, and the overall structure of the finally formed bridge is more reasonable in stress; and meanwhile, integral hoisting is adopted, a support system does not need to be arranged, aerial work is reduced to the maximum extent, and the construction efficiency is high.
本发明提供一种基于大跨度大重量钢混叠合梁的吊装施工方法，涉及桥梁工程技术领域。用于针对大跨度大重量的钢梁的桥梁吊装施工。本发明中钢梁的吊装顺序首先根据全桥温度变形最大区段和全桥温度变形最小区段进行钢梁的吊装，能够首先适应大梁段大位移的温度变形和大梁段小位移的温度变形，结合本专利中分段方式采用非标准分段的方式，能有效的避免梁段加工制造误差，使得最终成型的桥梁整体结构受力更加合理；同时本方法采用整体吊装，不需布设支架系统，最大限度的减少高空作业，施工效率高。
