Heightening installation method for prefabricated steel roof truss
The invention provides a heightened installation method for a prefabricated steel roof truss, and belongs to the technical field of steel roof truss installing.The prefabricated steel roof truss is divided into at least two roof truss part structures by dismantling a preset number of inter-shaft components at preset positions of the prefabricated steel roof truss which is basically installed and formed; then the roof truss part structure is integrally lifted to a preset elevation, prefabricated heightened steel columns are installed on the tops of concrete columns below the roof truss part structure and fixed to the roof truss part structure, and prefabricated side supporting trusses are installed on the two sides of a formed preliminarily heightened roof truss, so that the overall structure is stable; finally, the preset number of inter-shaft components are reinstalled to the corresponding positions of the stable and heightened roof truss. By means of reasonable design change and ingenious construction planning, refitting within a limited range is carried out, it is guaranteed that the steel roof truss meets the elevation requirement for heightening, large-area dismantling and reworking of a roof system are avoided, the design risk is avoided, and a large amount of material cost and time cost are saved.
本发明提供一种预制钢屋架的加高安装方法，属于钢屋架安装技术领，通过先在基本安装成型的预制钢屋架的预设位置处拆除预设数量的轴间构件，将预制钢屋架分成至少两个屋架部分结构；然后将屋架部分结构整体吊起升至预设标高，将预制加高钢柱安装至屋架部分结构下方的混凝土柱的顶部，并与屋架部分结构固定，在形成的初步加高屋架的两侧安装预制侧撑桁架，使其整体结构稳固；最后将预设数量的轴间构件重新安装到稳固加高屋架的对应位置；通过合理的设计变更和巧妙的施工策划，进行了范围有限的改装，既确保钢屋架达到增高的标高要求，又避免了屋面系统的大面积拆除返工，规避了设计风险，节约了大量的材料成本和时间成本。
