大型单层工业厂房屋面多采用钢屋架,吊装具有高处作业多、安全性差、质量要求高等特点,其施工方案也受施工单位机具设备条件、施工场地、工程规模等因素影响,因时因地而异。主要吊装方式有单榀吊装、双榀或多榀组合的综合吊装等。采用综合吊装方案时,地面组装很关键。由于柱顶标高常因施工因素影响而出现偏差,因此以往作法是在屋架吊装就位后用垫铁进行找
Large-scale single-story industrial plants mostly use steel trusses on the roof of the house. The hoisting has many features such as high work height, poor safety, and high quality requirements. The construction plan is also affected by the equipment and equipment conditions of the construction unit, the construction site, the project scale, and other factors. Different. The main lifting methods are single-lift, double-lift, or multi-turn assembly. When using an integrated hoisting scheme, ground assembly is critical. Due to the deviation of the column top elevation often due to construction factors, the past practice was to use horns to find the truss after it was lifted into place.
