Sheng steel silo, fabricated steel silo, silo Central Sheng silo available. We are filled steel silo Anyang City Development Co., Ltd. (www.aclsol.com) located at: Henan Anyang specializes in: Large steel base, cement silo, fly ash silo, grain silo, steel slag powder solve cement steel libraries and library at the end of the water seepage problem. This design uses the library bottom outer polymer waterproof materials and other technologies to the bottom of the library secondary reinforcement steel waterproof, steel and metal plates above the bottom library database library using corrosion-resistant waterproof material basis for the final barrier waterproof, steel library foundation and library at the end of the use of Concrete full waterproof, impermeable concrete. The scope of the design of a controlled prevention: waterproof grade level, grades 1-3 million tons of steel library leakage between P8-P12, libraries 5-20 million tons of steel between P12. Cement steel silo structure design should be based on the structure of the course load may occur simultaneously, according to the carrying capacity limit state and serviceability limit state load effect combinations, respectively, and taking into their most unfavorable combination meter design. Cement steel silo by ultimate limit state design should adopt the basic combination of load effects, load partial coefficient values ??according to the following provisions: a permanent load factors: unfavorable structure of steel silo, taking 1.2; structure favorable to wine silo, generally take 1.0; silos against overturning calculation, taking 0.9. 2 variable load factors: Chu cement load take 1.3; other variable loads take 1.4. 3 earthquakes take 1.3. Cement steel silo press limit state design, the short-term effect should be used in combination metal silo load, load factors were taken 1.0. Cement steel silo carried load combinations, variable load combination factors should be drawn to the following provisions : 1 No wind loads participation and assembled steel silo, taking 1.0. 2 wind load participation portfolio, cement load is 1.0; other variable load is 0.6. 3 have to participate in a combination of earthquake, cement loading take 0.9; seismic action taken 1.0; snow load take 0.5; wind load Excluding; floor variable load: according to practical considerations when taking 1.0, when you press the equivalent uniform load is 0.6.
