随着生产发展的需要,在中山县石歧镇建造一批小型工业厂房。为了节约钢材与木材,我们采用了磗薄壳作为屋盖。选择通用机械厂作为试点,其中金工车间鍛铸车间在1960年1月前先后竣工,并已投入生产两年,使用情况良好。 厂房长60米、宽24米、横向分为6米～12米～6米高低跨三跨(見图1)。柱网:边跨采用6×6米,中跨12×12米。尾盖:边跨采用6×6米,1/4磗双曲扁壳 With the development of production, a group of small industrial plants were built in Shiqi Town, Zhongshan County. In order to save steel and wood, we used a thin shell as a roof. The general machinery factory was chosen as a pilot project. The metalworking workshop forging workshop was completed before January 1960 and has been put into production for two years. The use situation is good. The factory building is 60 meters long, 24 meters wide, horizontally divided into 6 meters to 12 meters to 6 meters high and low span three spans (see Figure 1). Column net: 6 × 6 m for the side span and 12 × 12 m for the middle span. Tail cover: 6 × 6 m on the side span, 1/4 inch double curved shell
