1966年,我们第五冶金建设公司和重庆钢铁设计院在65厂平炉车间厂房的钢结构工程上,采用了高强螺栓连接技术。经过近十年的观察、检验,这个车间钢结构所有各连接部位的高强螺检均未松动,连接板均未滑移,各接点的强度和刚度足够,整个厂房结构的稳定性一直很好。 In 1966, our fifth metallurgical construction company and Chongqing Iron and Steel Design Institute adopted the high-strength bolt connection technology in the steel structure of the factory of the open-workshop of the 65th factory. After nearly a decade of observation and inspection, the high-strength screw inspections at all joints of the shop steel structure were not loosened, and the connecting plates were not slippery. The strength and stiffness of each joint were sufficient, and the stability of the entire plant structure was always good.
