钢结构的焊接与螺栓连接.docx

钢结构的焊接与螺栓连接 前言发展绿色生态建筑，是我国建筑发展战略的一个重要方向，在绿色生态建筑方面，钢结构厂房和住宅体系的推广应用和产业化是一个较好的切入点。随着国民经济的发展和国外技术的引进，建筑领域中的钢结构得到了迅猛的发展。钢结构工程以其工厂化作业程度高，材料低质高强、环保、节约能源等诸多优势，越来越多的被应用在国内较多的大型建筑中。钢结构节点施工质量的好坏又是关系整个钢结构体系安全的一个关键部分。 摘要 The connection method of steel structure components or parts of each other has weld connection, common bolt connection or rivets connection. Welding is early traditional steel structure connection. It dont weaken the welding section, and its a simple and automation method, a main connection of modern steel structure. But welding has the disadvantages that workload is big, high difficulty, and has serious damage to the environment so that it gradually replaced by bolt connection. Relative to the welding, the bolt connection of steel structure gradually began to spread, and develop ordinary bolt connection to the high strength bolt connection technique. And bolt connections environmental protection, high speed and strength fully adapt to the trend of the modern engineering. The rapid development of bolt connection is the important factor of prefabricated steel structure building to the popularity. In some heavy steel structure and light steel structure, high strength bolt connection has better than the on-site welding in comprehensive economic and rational, and its quality control also is more convenient than the on-site welding. So, with the construction steel structure project is industrialization, standardization, the high strength bolt connection have been applied more and more. Despite the current domestic mainstream method of steel structure connection is welding, but welding is gradually tends to lag behind, and high strength bolt connection is tend to be universal. For the construction efficiency and construction speed is concerned, the advantages of the bolt connection is far more than the welding connection. In the background of prefabricated building large scale popularization and development, as a quality and fast method, bolt connection will play a cr
