空间网架结构的优点是重量轻、刚度好、材料消耗少、施工进度快,最适用于大型屋盖体系。近年来国外采用这种结构建造了许多展览馆、会议厅、体育馆以及工业建筑等。空间网架是由简单的预制部件组装建造而成的。单个构件具有相同的尺寸和形式,可以在工厂成批生产,然后在现场拼装。单 The advantages of the space grid structure are its light weight, good rigidity, low material consumption, and quick construction progress, which is most suitable for large roof systems. In recent years, foreign countries have used this structure to build many exhibition halls, conference halls, gymnasiums, and industrial buildings. The space grid is assembled from simple prefabricated components. Individual components have the same size and form, can be mass produced at the factory, and then assembled on site. single
