Reverse installation construction method for tree-shaped steel huge column supported by hinged joint
The invention belongs to the technical field of building construction, and discloses a hinged joint supported tree-shaped steel huge column reverse installation construction method, which comprises the following steps of adopting a three-dimensional scanner to carry out reading measurement and ruler returning on a net rack attached to the top of a tree-shaped steel huge column, and building an on-site actual model of the steel net rack; all machining sizes and installation sequences are determined based on an on-site actual model, a reverse installation hanging bracket and a sling hanger of the tree-shaped steel huge column are arranged and lifted together with a net rack, and a temporary rigid lateral supporting structure is installed; the construction method provided by the invention is short in time consumption, less in overhead operation, suitable for increasingly complex steel structure engineering construction actual sites, also capable of meeting increasingly improved safety management standards, low in hoisting in-place difficulty, not easy to cause installation deviation, and capable of effectively overcoming the defect that the construction cost is low when a net rack adopts a ground splicing matched integral lifting process. The tree-shaped huge columns, serving as supporting structures, at the bottom of the steel net rack are forced to be inserted for construction, and the construction efficiency is high.
本发明属于建筑施工技术领域，且公开了一种铰接节点支撑的树状钢巨柱逆向安装施工方法，包括如下步骤：采用三维扫描仪对树状钢巨柱柱顶附着的网架进行抄测返尺，搭建钢网架的现场实际模型；基于现场实际模型确定各加工尺寸和安装顺序，设置树状钢巨柱的逆向安装吊架、吊索吊具，并与网架一同提升，安装临时刚性侧向支撑结构；本发明提供的施工方法耗时短、高空作业少，适用于日趋复杂的钢结构工程施工实际现场，也满足日益提高的安全管理标准，其吊装就位难度低，不易出现安装偏差，能有效克服网架采用地面拼装配合整体提升工艺时，导致钢网架底部作为支撑结构的树状巨柱被迫后插入施工的难题，施工效率高。
