近年来,在我国采用墙板的厂房不断增加,墙板的规格类型很多,有的达几十种,甚至上百种。为使钢筋混凝土预制构件逐步纳入工厂化生产,以促进建筑工业化的发展,必须尽量地减少构件的规格类型。因此,研究解决减少墙板规格类型的工作已成 In recent years, there has been an increase in the number of factory buildings using wall panels in China. There are many types of wallboards, some of which are dozens or even hundreds. In order to gradually incorporate reinforced concrete prefabricated components into factory production to promote the development of building industrialization, it is necessary to reduce the type of component specifications as much as possible. Therefore, research to solve the problem of reducing the type of wallboard specifications has become
