近几年苏联发展起一个新的建筑工业部门——在工厂生产、配套供应轻结构(每平米围护结构重150公斤以下)的部门。占全部工业建筑约60%的统一标准厂房(单元)体系共采用五种承重结构(表1)。其中三种为网架屋盖。生产网架结构的工艺线的年产能力为二亿平方米,占轻钢结构制造厂全部生产能力的很大部分。空间格构钢结构体系以及由此演变而来的规则角锥网架结构体系,在各种先进结构中占有领先地位。与传统的平面结构相比,它们具有许多优点。其中主要的有:构件最大限度统一化,为自动化生产创造条件;可
In recent years, the Soviet Union has developed a new construction industry sector - a factory that manufactures and supplies light structures (less than 150 kilograms per square meter of building envelope). A total of 5 load-bearing structures are used in the unified standard factory building (unit) system, which accounts for about 60% of all industrial buildings (Table 1). Three of them are grid roofs. The annual production capacity of the production line of the production grid structure is 200 million square meters, which accounts for a large part of the total production capacity of the light steel structure manufacturing plant. The space lattice steel structure system and the regular pyramid network structure system evolved from it have occupied a leading position in various advanced structures. They have many advantages over traditional planar structures. The main ones are: the maximum unity of components, creating conditions for automated production;
