[Sichuan] Industrial plant steel structure Installation method statement
This project is: the 10m2 shaft furnace pelletizing plant construction project of XX Co., Ltd. - steel structure sub item, designed by Anhui Masteel Engineering Technology Co., Ltd. and contracted by XXXX Construction Co., Ltd. The project site is located in Leba Town, XX County, Bazhong City, Sichuan Province. The project is a steel structure and reinforced concrete plant, with a total floor area of 32166m2. The steel structure part mainly includes the following devices: shaft furnace room: building elevation is 30.490m (calculated based on indoor ± 0.000), columns on both sides are 16.100m away from A-D axis, and 23.300m away from 1-5 axis. The largest component is the steel column at the intersection of axis B and axis 2, which is a cross square steel column with a length of 28.700m and a weight of 9.5t. The foundation form is -1.800m cup foundation; Pelletizing chamber: the building elevation is 13.630m (calculated based on indoor ± 0.000), the distance between columns on both sides is 17.000m from A-D axis, 18.000m from 1-3 axis, the largest component is the steel column at the intersection of axis C and axis 2, which is H-shaped steel column, 15.230m long, 3.5t weight, and the foundation form is -1.600m cup foundation; The fire resistance rating of the steel structure of the project is Level II, the fire resistance limit of the frame beam and column is 2.5h, the fire resistance limit of the secondary beam is 1.5h, and the fire resistance limit of the purlin is 1.0h. The surface of the steel member is coated with fire retardant coating.
