随着社会主义建设事业的飞跃发展,工业建筑物大量建造,许多新型的结构不断湧现;为了有效的完成这些任务,我们就必须以工厂化制造和机械化施工相结合的施工方法进行工作.如何充分发挥现有设备的潜在能力,改进施工方法,是提高劳动生产率、降低建造成本的重要保证.新型的大、中、小型工业车间正在广泛地采用重型承重结构以及大块的围护结构(如1.5~M×6.0~M大型屋面板);而且这种结构还在不停地改进,以 With the rapid development of socialist construction, a large number of industrial buildings have been built, and many new types of structures have emerged. In order to accomplish these tasks effectively, we must work with a combination of factory manufacturing and mechanized construction methods. Extending the potential capabilities of existing equipment and improving construction methods are important guarantees for increasing labor productivity and reducing construction costs. New types of large, medium and small-sized industrial plants are widely adopting heavy-duty load-bearing structures and large-scale envelope structures (such as 1.5 ~M×6.0~M large roof panels); and this structure is constantly improving to
