轻钢结构的优点是节材高效,耗钢少,自重轻,制造安装运输简便,工期短,可拆迁,定型批量生产易于实现商品化等,近年来发展迅速,特别是门式刚架轻钢结构工业厂房应用日益广泛。为达到进一步减少钢耗,降低成本的目的,还可以采用各种先进的科技手段,如引入预应力技术以加强结构刚度和承载力,提高结构稳定性,若能在檩条中张拉板材可以防止风吸力下的局部失稳和提高弹性受力幅值,将可大大减少檩条的用钢量,因此,对门式刚架轻钢结构工业厂房施工技术及质量控制措施进行分析与探讨有较强的现实指导意义。
The advantages of the light steel structure are high efficiency in material saving, low steel consumption, light weight, simple manufacture, installation and transportation, short construction period, relocation, stereotyped mass production and easy commercialization, etc., and the rapid development in recent years, especially the light steel with portal frame The use of structural industrial plants has become increasingly widespread. In order to further reduce steel consumption and reduce costs, various advanced technological means can also be adopted, such as the introduction of prestressing technology to enhance the structural rigidity and bearing capacity, and improve the structural stability. If the sheet can be stretched in the purlin, it can prevent The local instability under wind suction and the increase of the elastic force amplitude will greatly reduce the amount of steel used for purlins. Therefore, there is a strong analysis and discussion on the construction technology and quality control measures of the portal plant with light steel structures. Realistic guidance significance.
