Structural Requirements For Steel Structure Poultry Building

Foundation and Floor: The foundation should be deep and solid. The floor must be higher than outside the house, moisture-proof, flat, and easy to clean and disinfect.

Walls: Good thermal insulation properties and can protect against external wind and rain. They are mostly built with bricks or stones, cement joints on the outside, and cement or white ash inside to prevent moisture and facilitate erosion. Roof: Double-slope roofs are generally used except for single-slope roofs for tiny chicken houses with small flat spans. 

Doors and windows: Doors are generally located on the south side of the south-facing chicken house. The door size is generally a single door with a height of 2 meters and a width of 1 meter, a double door with a height of 2 meters and a width of about 1.6 meters. The windows of the steel structure poultry building should be located on the front and rear walls, and the front window should be broad and low to the ground to facilitate lighting. The ratio of windows to ground area is 110 to 18. The rear window should be small, about 2/3 of the front window area, and can be higher from the ground to facilitate ventilation in summer. There are no windows in a closed chicken house, only emergency windows, ventilation inlets, and outlets. 

House span, length, and height:

The span of the steel structure poultry building depends on the form of the chicken house roof, the type of chicken house, and the feeding method. The general span is 6 to 10 meters for open chicken houses and 12 to 15 meters for closed chicken houses. The length of the steel structure poultry building generally depends on the span of the chicken house and the degree of mechanization of management. Chicken houses with a span of 6 to 10 meters are usually 30 to 60 meters long; chicken houses with a larger span, such as 12 meters, are generally 70 to 80 meters long. Chicken houses with a higher degree of mechanization can be longer, but generally, they should not exceed 100 meters. Otherwise, the production and installation of mechanical equipment will be more complex, and the materials will not be easy to deal with. The height of the steel structure poultry building should be determined according to the feeding method, manure cleaning method, span, and climatic conditions. The chicken house does not need to be too high in areas with small spans, dry farming, and not-too-hot regions. Generally, the eaves height of the steel structure chicken house is 2.0 to 2.5 meters; if the span is large and it is a multi-layer cage, the chicken house is about 3 meters or more. The uppermost chicken coop is preferably 1 to 1.5 meters away from the roof; if it is a high-bed closed chicken coop, the height is generally 4.5 to 5 meters (1.8 to 2 meters higher than ordinary chicken coops) due to the manure pit at the bottom. 

Operation room and aisle: The operation room is where the breeder performs operations and stores tools. If the length of the steel chicken house does not exceed 40 meters, the operation room can be located at one end of the chicken house. If the size of the chicken house exceeds 40 meters, it should be found in the center of the chicken house. The location of the walkway depends on the span of the chicken house. The span of a flat chicken house is relatively small, and the walkway is generally located on one side of the chicken house, with a width of 1 to 1.2 meters. When the span is greater than 9 meters, the walkway is located in the middle, with a width of 1.5 to 1.2 meters—1.8 meters, convenient for feeding by trolley. No matter how large the span of the cage chicken house is, it depends on the arrangement of the chicken cages. The walkway between the chicken cages is 0.8 to 1.0 meters. Sports ground: When open chicken houses are raised on flat ground, there is usually a sports ground. The sports field is the same length as the chicken house, and the width is about twice the span of the chicken house.
