Steel construction broiler chicken house
Brief Introduction of Poultry House:
Steel Framework: Galvanized Steel Framework, included H section steel beam, H section steel column, roof purlin. (All parts are bolted together)
Brief Introduction of Poultry House
Main Structure
(Steel tube truss system)we adopt hot-dip galvanizing C section or steel tube truss beam to reduce self-weight of design load and dosage of the steel. At the same time, hot-dip galvanized can widely improve anti-corrosion of the steel. (The construction cycle of the steel structure work is short, which reduces the cost of the project effectively. The steel structure has strong shock resistance and can improve the comprehensive anti-seismic property of the whole house).
Substructure(Cold-formed thin-walled steel)
Roof purlin uses the hot-dip galvanized Z or C section. The way to continuous lap makes the steel frame as whole. Roof purlin uses the hot-dip galvanized C section steel. All components adopt bolted connection, no welding, which makes the structure overall appearance smooth.
Protecting system
In order to satisfy the protecting material for 20 years, the outside roof is 0.5 mm aluminum zinc color steel plate. To prevent dewing phenomenon, 50 mm aluminum foil glass wool is laid at the bottom of the roof plate (can be customized according to the climatic conditions). To prevent sagging of the fiber wool, the wire mesh is added, which effectively improve the utilization rate of the glass wool insulation and moisture proof. To add ceiling panels below steel trusses and the ceiling panels laid horizontally is composite color plate, which not only improves the overall stability of steel trusses, but also plays a very good thermal insulation effect. The inside and outside walls laid horizontally is hot-dip galvanized color steel plate, which are all used self-tapping screw to connect into a whole, effectively increasing the lateral stability of steel columns. The indoor humidity is relatively large, so a layer of plastic film is added in order to prevent moisture from entering the fiber glass wool.
Basic rules of structure design
1. Design code for steel structure GB50017-2003;
2. Design Specification for Curved Thin-walled Steel Structure GB50018-2002.
Design parameters
1. Coefficient for importance of a structure is 0.95. The usage life is 25 years;
2. 3 security level;
3. Seismic fortification categories: C-class;
4. Earthquake-resistant level: the main structure is level four.
Structural design load
Uniformly distributed load standard values:KN/m2
1. YX-980 0.5mm outsider roof aluminum-zinc steel plate: 0.049KN/m2;
2. 16kg/m3 50mm heat-insulating fiber glass wool: 0.008 KN/m2;
3. Z or C roof purlin: 0.034 KN/m2;
4.Roof live load: 0.5 KN/m2.
Concentrated load:KN/m2(3mis a lifting point)
1. Waterline : 0.11 KN/m2;
2. Feed line : 0.22 KN/m2;
3. Motor(the end of waterline and feed line): 0.41 KN/m2;
4. Full load of hopper : 1 KN/m2;
5. Main feed line : 0.18 KN/m2;
6. Wind load : 0.6 KN/m2;
7. Snow load : 0.5 KN/m2.
Material
Load-bearing structural steel (steel column, steel beam) usually adopt Q235 and Q345. According to machinery performance and chemical composition, Steel should be Q235B which conforms to the requirement of current national standard high strength low alloy structural steel (GB/T1591-94) and (GB1591-88).
The ration of the steel tensile strength and yield strength measured value should not be less than 1.25, and there is obvious yield level. Elongation should be more than 20%, and has good weld ability and qualified impact toughness.
