Installation method of large-span steel truss overhanging special-shaped structure
The invention provides an installation method of a large-span steel truss overhanging special-shaped structure, which comprises a permanent support column, a temporary support column, a truss beam, a cantilever beam and a steel bar truss floor support plate, and the permanent support column and the temporary support column are used as support seats of the truss beam; the truss girder is of an arc-shaped steel truss structure, the two arc-shaped ends are connected with adjacent building components, and the cantilever beam is attached to the arc-shaped section of the steel truss and is in a double-layer radial shape. The steel bar truss floor support plate is laid on the cantilever beam, and concrete is poured in the later period to serve as a building structure floor; according to the method, components are partially and integrally spliced and then hoisted, and the frequency of aerial work of personnel is reduced as much as possible; the stress working conditions such as structure hoisting and temporary supporting are accurately and comprehensively analyzed, and then actual operation is carried out; the construction method is safe and reliable; the method is simple in structure and wide in application range, and has good applicability for complex steel structure installation and construction, especially for cantilever structures with many numbers.
本发明提供了一种大跨度钢桁架悬挑异型结构的安装方法，包括永久支撑柱、临时支撑柱、桁架梁、悬臂梁和钢筋桁架楼承板，永久支撑柱与临时支撑柱作为桁架梁的支撑座；桁架梁为弧形钢桁架结构，弧形两端与相邻建筑构件相连，悬臂梁附着于钢桁架的弧形段上，呈双层放射状；钢筋桁架楼承板敷设于悬臂梁上，后期浇筑混凝土作为建筑结构楼板；该方法将构件进行部分整体拼装后吊装，尽量减少人员高空作业的频率；结构吊装、临时支撑等受力工况采用精确、全面的分析，然后再实际操作；施工方法安全可靠；适用范围广，对于复杂的钢结构安装施工，特别是悬臂结构较多的，采用本方法及思路，具有较好的适用性。
