External expansion type construction method for large-span aluminum alloy single-layer reticulated shell dome structure
The invention relates to the technical field of reticulated shell dome construction, in particular to an external expansion type construction method for a large-span aluminum alloy single-layer reticulated shell dome structure, which comprises a supporting jig frame, a steel ring beam is mounted on the outer wall of the upper end of one side of the supporting jig frame, and the supporting jig frame and the steel ring beam are mounted in a matched manner to form an elliptical structure; the method has the beneficial effects that the problem of surveying and setting-out of a complex space reticulated shell structure is solved through a space positioning measurement technology, the splicing error of a steel-aluminum structure is eliminated by adopting a post-mounting mode of a connecting piece between an aluminum alloy reticulated shell dome and an outer ring steel structure ring beam, and construction is performed by adopting an externally-expanded ring-by-ring mounting method, so that the mounting efficiency of the reticulated shell structure is improved, and the construction cost is reduced. And the mounting quality is effectively controlled.
本发明涉及网壳穹顶施工技术领域，具体为一种大跨度铝合金单层网壳穹顶结构“外扩式”施工方法，包括：支撑胎架，支撑胎架的一侧上端外壁安装有钢环梁，支撑胎架和钢环梁配合安装为椭圆形结构；有益效果为：通过空间定位测量技术，解决了复杂空间网壳结构的测量放线难题，通过采用铝合金网壳穹顶与外圈钢结构环梁间连接件后装方式，消除钢铝结构拼装误差，采用“外扩式”环环相扣的安装方法施工，提高了网壳结构安装效率，有效控制安装质量。
