如果把当前的建筑结构材料进行分类,主要就三种:钢材、木材、混凝土。用于索膜结构的只能抗拉的有机材料,因其用量极小,可忽略不计。“空中造楼机”发明人董善白先生认为:前两种是“天生”的装配式建筑构件,适合在工厂制作、加工,但混凝土就不同了。混凝土构件当然可以在工厂预制,但构件连接处的
If the current classification of building materials, mainly three: steel, wood, concrete. The tensile-resistant organic material used for the membrane structure is negligible because of its extremely small amount. Mr. Dong Shanbai, the inventor of “Aerial Building Machine,” said: The first two are “natural” assembly type building components that are suitable for making and processing in the factory, but the concrete is different. Concrete components can of course be prefabricated at the factory, but the components are joined together
