Unit type hoisting construction method for large-span and ultra-long overhanging plane steel pipe truss roof
The invention discloses a unit type hoisting construction method for a large-span and ultra-long overhanging plane steel pipe truss roof, which comprises the following steps of: carrying out steel structure construction deepening design in advance before steel structure construction, determining hoisting weight and hoisting piece length according to a construction environment, operation conditions and maximum hoisting capacity of construction machinery, and carrying out hoisting construction according to the hoisting weight and the hoisting piece length. The maximum hoisting capacity of a construction machine is fully utilized, a main body structure is divided into large hoisting units as much as possible according to the maximum hoisting capacity of the construction machine, high-altitude operation and hoisting of scattered rod pieces are reduced as much as possible through hoisting unit division, the hoisting units are reasonably divided, all the hoisting units are segmented and assembled on the ground, and then air butt joint hoisting is conducted. Ground welding and high-altitude hoisting are convenient, high-altitude welding is greatly changed into ground welding, the welding quality, the construction safety and the construction progress are more easily and effectively controlled, the construction period is effectively shortened, the installation cost is effectively reduced, and high popularization value is achieved.
本发明公开了一种大跨度、超长悬挑平面钢管桁架屋盖单元式吊装施工方法，在钢结构施工前提前进行钢结构施工深化设计，根据施工环境、作业条件、施工机械的最大起重能力，确定吊装重量及吊装件长度，充分利用施工机械的最大起重能力，将主体结构按施工机械的最大起重能力尽量分为大吊装单元，吊装单元划分尽可能减少高空作业和零散杆件的吊装，且吊装单元划分合理，将各吊装单元分段并进行地面拼装，再进行空中对接吊装，地面焊接及高空吊装方便，通过大量地将高空焊接改为地面焊接，更易有效控制焊接质量、施工安全及施工进度，有效节约工期及降低安装成本，具有较高的推广价值。
