随着我国国民经济的快速发展,轻钢结构的应用日益广泛。特别是轻钢门式刚架这种房屋结构形式,在工业厂房、公路(铁路)库、仓库、飞机库、集贸市场、体育场馆、航空港、商业建筑中越来越得到人们的青睐。在我国已建成的此类工程已达800多万m~2,而且每年以200多万m~2的速度增长,不但国外许多厂家纷纷涌入我国,国内的许多钢结构厂家也转入此类构件的生产。以下就轻型门式刚架的特点及工程中的应用作一简单介绍。 With the rapid development of our national economy, the application of light steel structure is increasingly widespread. In particular, the light steel portal frame is a type of housing structure that is gaining increasing popularity among industrial buildings, roads (railroads), warehouses, hangars, bazaars, stadiums, airports, and commercial buildings. In China, more than 8 million m 2 of these projects have been completed and have grown at an annual rate of over 2 million m 2. Not only many foreign manufacturers have flooded into our country, many domestic steel manufacturers have also moved into this category Production of components. Following on the characteristics of lightweight gantry and engineering applications for a brief introduction.
