多跨大面积厂房有工艺布置紧凑、节约占地面积、减少外围护结构、节约能源、降低单位建筑造价等优点。尤其在近代大工业生产水平的高速发展、机械化自动化程度的提高,以及工业用地紧张等情况下,大面积厂房的出现一定会成为必然的趋势。 The multi-span large-scale factory buildings have the advantages of compact layout, saving of floor space, reduction of external protective structures, energy conservation, and reduction of unit construction cost. Especially in the modern high-tech industry, the rapid development of the level of production, the degree of automation of mechanization, as well as the tension of industrial land, and so on, the emergence of large-scale plant will certainly become an inevitable trend.
