Chicken coop construction regulations

1. The construction of the chicken coop first considers the local natural climate, and prevents the damage to the chicken coop caused by floods, rains, and extreme weather in advance. In areas with long-term rainfall, the viewing angle of flat roof can be slightly larger and not lower than 12°C; in areas with strong winds, the angle of view of flat roof can be smaller and not higher than 11°C. In areas with heavy snowfall, the compressive strength of steel roof trusses must be high enough .

2. The construction of the chicken coop must take into account the anti-corrosion properties, and the commonly used raw materials can resist acid and alkalinity.

3. The construction of closed chicken coops must ensure that three properties are good: fire resistance, thermal insulation, and closed type.

Regulations on raw materials for the construction of closed chicken coops

1. Ensure good fire resistance and thermal insulation: In areas where the temperature is lower than -10°C for a long time in winter, the thickness of the wall should not be less than 37 cm, and the color of the flat roof should not be less than 15 cm high foam. The location where the temperature is lower than -20°C needs to be pasted with a 5cm high-foam thermal insulation layer within the 37cm wall. In the area where the temperature is around -5°C in winter, the thickness of the wall should not be less than 24cm. The high foam of not less than 15 cm (1 square meter is about 13kg up and down is suitable) and must be a fireproof material. The eaves can be up and down for 30 minutes when the eaves exceed the wall.

2. Ensure that the closed type is good: ensure that the built chicken house cannot have evil winds entering (the flat roof and the corners, front and rear doors, manure outlet, middle egg outlet, etc. need to be closed and tight, and the front and rear doors are all selected doors. side door). The emergency window is not repaired at the axillary corner (an emergency door of 2m*1.2m*3/axillary corner can be selected, but it must be sealed with structural glue usually).

3. For sandalwood strips, use 80*40*2.5/100*50*3 hot-dip galvanized rectangular square tubes with an interval of no more than 1.1 meter. Do not use C-shaped steel (C-shaped steel is easy to corrode, hides dust and mice, etc.)

4. The inclined support point of the exhibition surface can be welded by electric welding of 80*40*2.5/100*50*3 hot zinc rectangular square tube or 24# I-beam raw material. Pay special attention when applying the I-shaped outline, and the bottom must be pushed. , so that a complete prefabricated component can be built as a whole to improve the bearing capacity; in addition, after the steel roof truss is completed, every span is sealed with building templates/color steel tiles to increase the total area of ​​the wind circulation system.

5. To improve the impact resistance of the chicken house, at least one span of scissors is placed in the front, middle and rear of the chicken house. Triangular plates are welded between the vertical pole and the road surface, the roof and the surface of the sandalwood, and the overall structure is more solid.

Regulations for the construction of pavement for closed chicken coops

The thickness of concrete on the pavement of the chicken coop should not be less than 120mm. The unique geological environment (such as the backfill road) needs to be thickened or structurally reinforced; the inclination of the pavement in the front, rear, left and right directions and up and down directions of the chicken coop should not be made (the tail dung removal ditch can be made moderately). Steep slopes of a few centimeters), the more tidy the better, and the road surface should be polished after it is done to prevent anti-sand, resulting in the trouble of cleaning.

Regulations for the construction of canals in closed chicken coops

Except for the manure removal ditch at the tail, there will be no ditch in the chicken house. Some pig farmers make sewage ditches on both sides or in the middle of the house in order to better clean the house, which is extremely bad for the cleanliness of the house and the prevention of flies and fouling. It is suggested that a 300mmx300mm semi-circular drainage ditch (this ditch can be slightly inclined) can be made 80 cm away from the tail manure removal ditch (towards the front of the chicken house) to discharge the waste water from the cleaning house to prevent environmental pollution. manure ditch.

Regulations for the construction of water curtains in closed chicken houses

The distance between the water curtain and the chicken is not less than 2.5m, and the water curtain needs to be installed with air-conditioning fan blades. Therefore, the front water curtain is installed 50 cm out of the wall (to prevent the water curtain from entering the water, and the water is injected into the chicken house), and the side water curtain is out of the wall. 1.5m installation. The aspect ratio of the side wind window needs to be higher than the top net of the chicken cage by 40 cm, and the side wind window should be made on the water curtain in front of the chicken house.

Regulations for the construction of water curtain supply reservoirs in closed chicken coops

The water curtain power supply reservoir should not be installed in the middle of the water curtain and the wall. It is easy to cause water pollution and air pollution in the chicken house. It is recommended to be installed on the basic side of the water curtain.
