Construction method of large-span columnar bolt-sphere joint grid
The invention belongs to the technical field of building construction, and discloses a large-span columnar bolt-sphere joint grid construction method which comprises the following steps: construction preparation; carrying out basic measurement and rechecking; checking and sorting entering components; mounting a bracket: starting to mount the gable net rack, follow-up mounting the arched net racks on the two sides, setting a temporary support, folding and correcting the arched net racks on the two sides, hoisting and correcting a small unit, and welding a support; the installed net rack is subjected to anti-corrosion and fireproof coating; and acceptance. A construction method combining a block installation method and a high-altitude bulk method is adopted, a construction method of a gable starting and deflection control method is utilized to complete installation of the starting net rack, tensioning ropes and temporary supporting rods are additionally arranged in a segmented mode in the starting rack assembling process, the design camber and the appearance size of the net rack are guaranteed, and the construction efficiency is improved. And the rest part of the net rack is mounted by adopting a method of performing high-altitude assembly towards one end by taking the starting rack as a reference, and the net rack gable wall is constructed by adopting a construction method of performing high-altitude assembly from one end to the other end.
本发明属于建筑施工技术领域，且公开了一种大跨度柱状螺栓球节点网架施工方法，包括以下步骤：施工准备；基础测量及复核；进场构件清点和分拣；支架安装：对山墙网架起步安装，两侧拱形网架跟进安装，设置临时支撑设置，两侧拱网架形合拢并校正，小单元吊装，校正，支座焊接；对安装好的网架进行防腐、防火涂装；验收。本发明采用分块安装法和高空散装法相结合的施工方法，利用“山墙起步、挠度控制法”的施工方法完成起步网架安装，起步架拼装过程中分段增设张紧绳和临时支撑杆，保证网架设计拱度和外形尺寸，其余部分的网架安装方法采用以起步架为基准向一端进行高空散拼的方法，网架山墙采用从一端开始向另一端进行高空散拼的施工方法。
