在设计革命运动中,我们设计出一些适合我国情况的、能够减轻建筑物自重的轻型构件。例如适合于中小型厂房用的钢筋混凝土门式刚架、组合式小屋架、钢筋混凝土Γ形檩条等承重构件,以及钢丝网水泥折板瓦、钢筋混凝土Γ形板等屋盖构件。现就试点工程中采用轻型构件的情况作一些介绍。 一、试点工程的概况 这些轻型构件,经过试验后已在几个城市的四、五个试点工程中采用。有的已建成,有的正在施工(图1、表1)。实践证
In the design revolutionary movement, we designed some lightweight components that are suitable for our country and can reduce the weight of buildings. For example, it is suitable for heavy-concrete portal girders, modular huts, reinforced concrete purlins and other load-bearing components used in small and medium-sized factories, as well as roofing components such as wire mesh concrete folding slats and reinforced concrete stiles. We will now give some details on the use of lightweight components in pilot projects. I. Overview of Pilot Projects These lightweight components have been tested in four or five pilot projects in several cities. Some have been completed, and some are under construction (Figure 1, Table 1). Practice certificate
