1. In the middle and late application of the dry coal shed space frame, the corrosion resistance of its own stainless steel sheet is weak, because it is impossible to completely block the gas with architectural coatings on the construction site, and it is in a closed and restricted space, accumulating The unique chemical substances such as coal also have many uncertain factors, which cause and accelerate the corrosion of the steel structure.If there is a lack of timely maintenance measures during application, and in the whole process of application, if you do not pay attention to the extrusion of the rubber bearing and the bending of the components caused by the stacking pressure of coal, this will give safety to different levels. lead to a safety hazard or an immediate accident.
2. At the construction site of the space frame of the dry coal shed, in order to control the cost or not attach great importance to the construction party, the construction party will not carry out the engineering construction or timely engineering construction of the fireproof material for the surface layer of the steel structure. The heat resistance of stainless steel sheet is weak, and many of its properties change with the rise and fall of temperature. When the temperature reaches 430-540 °C, the yield limit, compressive strength and elastic mold of the stainless steel sheet will be greatly reduced, and the bearing capacity will be lost.
