1986年8月,苏联在安装诺沃阿利得让斯克面粉厂的粉磨工段框架结构时,发生了一起6层框架倒塌的事故。该粉磨工段的平面尺寸为18×48m,高35m,处于谷物清理工段和成品工段之间。按设计,粉磨工段应是7层框架结构,设计套用多层工业厂房装配式钢筋混凝土结构标准设计1.420-12,柱网尺寸是6×9m,楼板为工型断面,支承在横梁的翼缘上。厂房的基础是现浇的十字交叉带形基础,外墙为轻骨料混凝土悬挂外墙板,内墙和隔墙是砖砌的。
In August 1986, when the Soviet Union installed the frame structure of the pulverizing section of the Novo Alleghensk Flour Mill, a six-story frame collapse occurred. The plane size of the pulverization section is 18×48m and height is 35m, and it is between the clear grain section of the grain and the product section. According to the design, the grinding section should be a 7-story frame structure. The design applies a multi-layered industrial building. The standard design of a reinforced concrete structure is 1.420-12. The column size is 6×9m. The floor is an engineering section and supported on the flange of the beam. on. The factory building is based on a cast-in-place cross-belt foundation. The exterior wall is made of lightweight aggregate concrete hanging wall panels. The interior walls and partition walls are brickwork.
