Steel structure steel by Q235, Q345, Q390, Q420. 6, landing fire shall not be less than 1 hours, the ladder is not less than 0.25 hours. 7, the apron width should be 0.6-1 meters, generally more than the cornice is 0.2-0.3 meters, 20-30 meters expansion joint. Apron and wall set the gap width of 20-30 mm, aproll slope 3%-5%. 8, open to the public aisle windows, the bottom height of not less than 2 meters, 0.8 meters lower than the set protection measures. 9, fire doors, fire window, division three, 1.2, 0.9, the fire resistance limit of 0.6 hours.
