Technical Field
[0001] This invention belongs to the field of agricultural and livestock building technology, specifically, it relates to a fully prefabricated double-layer pig farm building and its construction method. Background Technology
[0002] Against the backdrop of the booming development of the large-scale pig farming industry today, the traditional pig farm building structure and construction methods have revealed many drawbacks.
[0003] On the one hand, traditional pigsties mostly use red brick masonry structures, steel frame structures, etc., which require a large amount of on-site construction work. This not only consumes a lot of time and labor, but also wastes a lot of materials, resulting in high investment costs. In addition, a large amount of solid waste is generated during the construction process, causing noise, dust, water pollution, etc., which cause serious secondary pollution to the environment.
[0004] On the other hand, traditional pigsties are mostly single-story structures, occupying a large area, resulting in low land utilization efficiency and increased unit investment costs. Their standardization is low, with structural design often relying on the pig farmers' concepts and experience. Construction quality is affected by capital investment and the skill level of construction workers, lacking unified standards, leading to unreasonable structures, poor quality, and significant difficulty and cost in later upgrades and renovations.
[0005] Meanwhile, the low level of automation in animal husbandry, including manual feeding, environmental control, and manure removal, not only increases labor costs but also makes farm management more difficult and reduces efficiency. Furthermore, traditional pigsty manure cleaning is difficult, with low efficiency, high water consumption, and incomplete separation of wet and dry waste. Existing manure treatment facilities are mostly civil engineering projects, which occupy large areas, have high costs, and low treatment and utilization efficiency, greatly hindering subsequent manure treatment and resource utilization.
[0006] Furthermore, as the scale of the pig farming industry continues to expand, the demand for efficient utilization of breeding space and precise control of the breeding environment is becoming increasingly urgent. Although some pig farms have achieved partial prefabricated construction, they have not yet achieved fully prefabricated construction as a whole, which makes it difficult to meet the needs of the rapid and standardized development of the pig farming industry.
[0007] Therefore, there is an urgent need for an innovative fully prefabricated double-layer pig farm building structure system and its construction method to overcome the shortcomings of the traditional model. Summary of the Invention
[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an agricultural and livestock breeding building that can overcome or at least partially solve the above problems.
[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a fully prefabricated two-story pig farm building, comprising: The main structure, from top to bottom, consists of a roof truss, a double-layer breeding area, and a manure collection area, with an outer enclosure. The main structure, excluding the roof truss, adopts a fully prefabricated reinforced concrete frame structure, and the horizontal load-bearing components adopt standardized fully prefabricated beams and fully prefabricated ribbed plates.
[0010] Furthermore, the double-layer breeding area includes upper and lower passageways and multiple breeding rooms located on both sides of the passageways.
[0011] Furthermore, the feeding room is divided by partitions and prefabricated wall panels. The front part of the partitions near the passageway is equipped with breeding equipment, and the rear part is equipped with a prefabricated manure-leaking panel.
[0012] Furthermore, the sewage collection area is located below the precast slab with a slatted floor. The bottom slab of the sewage collection area is a fully precast slab with ribs at the bottom. The ribs and the floor slab are cast and precast together in the component factory.
[0013] Furthermore, the fecal waste collection area includes a cleaning ditch and a collection tank. The cleaning ditch has a smooth surface, is wider at the top and narrower at the bottom, and has an inclined slope, which enables automatic cleaning and centralized collection of fecal waste.
[0014] Furthermore, the breeding equipment includes an automatic feeding module, a constant temperature and humidity ventilation system, lighting equipment, and an Internet of Things (IoT) control system. The automatic feeding module consists of a waterer, a feeder, and a controller, which can automatically feed and water the pigsty at set times and in set quantities. The constant temperature and humidity ventilation system can regulate the temperature, humidity, and ventilation in the pigsty to provide a comfortable growth environment for the pigs. The IoT control system can realize real-time monitoring and intelligent management of the pigsty environment and breeding process.
[0015] Furthermore, the enclosure consists of prefabricated partition walls and insulation materials.
[0016] Furthermore, the width of the precast concrete slab with a manure leakage feature is 600mm or 800mm.
[0017] Furthermore, the roof truss is set on top of the main structure, and a light steel frame is covered with color steel plate pitched roof.
[0018] A construction method for a fully prefabricated two-story pig farm building, mainly including the following steps: Step 1: Factory Prefabrication: According to the design requirements, the main structure, roof truss, enclosure, feeding partition walls, slatted floor, and fully prefabricated ribbed panels are prefabricated in the factory.

The main structure is installed using hoisting, assembly, and welding processes. Step 5, Roof Truss Installation: A modular assembly method is adopted. First, the anchor bolts at the bottom of the square steel tube column are positioned and the embedded parts are corrected. High-strength bolts or self-tapping screws are used for node connection. A temporary support system is used to ensure structural stability. Corrosion protection is carried out simultaneously during construction. The durability is improved by galvanizing or spraying fireproof and anti-corrosion coatings. Step Six: External Enclosure Installation: Install the external enclosure to form a semi-enclosed pigsty; Step 7: Installation of internal facilities: Install internal partition walls and slatted flooring in the pigsty; Step 8: Installation of breeding equipment: Install feeding modules, constant temperature and humidity ventilation equipment, lighting equipment, Internet of Things control system and other breeding equipment; Step Nine: System Debugging and Acceptance: Conduct a comprehensive debugging and acceptance test on the entire building system and its equipment to ensure that all functions are operating normally.

[0028] The sewage collection area 3 is located below the slatted precast slab. The bottom slab of the sewage collection area 3 is a fully precast slab with ribs at the bottom. The ribs and the floor slab are cast and precast together in the component factory.
[0029] The fecal waste collection area 3 includes a fecal cleaning ditch and a fecal collection tank. The fecal cleaning ditch has a smooth surface, is wider at the top and narrower at the bottom, and has an inclined slope, which can realize automatic cleaning and centralized collection of fecal waste.
[0030] Fecal waste collection area: Located below the precast slab with slatted floor. The septic tank floor slab innovatively adopts a fully precast slab with ribs at the bottom. The ribs and the floor slab above are cast and precast together in the component factory, which can effectively improve the load-bearing capacity of the septic tank floor slab.
[0031] Precast deep beams are used on the exterior of the building to serve as the side walls of the septic tank. The connection between the precast deep beams and the precast columns of the outer frame is achieved through a reserved post-cast section, which can effectively ensure the mechanical performance and anti-leakage ability of the connection nodes.
[0032] The fecal waste collection area includes a cleaning ditch and a collection tank. The cleaning ditch has a smooth surface, is wider at the top and narrower at the bottom, and has a sloping surface to enable automatic cleaning and centralized collection of fecal waste, facilitating subsequent treatment and resource utilization.
[0033] The breeding equipment includes an automatic feeding module, a constant temperature and humidity ventilation system, lighting equipment, and an Internet of Things (IoT) control system. The automatic feeding module consists of a waterer, a feeder, and a controller, which automatically feeds and waters the pigsty at set times and in set quantities. The constant temperature and humidity ventilation system regulates the temperature, humidity, and ventilation in the pigsty to provide a comfortable growing environment for the pigs. The IoT control system enables real-time monitoring and intelligent management of the pigsty environment and the breeding process.

[0036] Enclosure 4 consists of prefabricated partition walls and insulation materials.
[0037] Enclosure 4: Composed of prefabricated partition walls and insulation materials, it has good insulation performance, which can reduce heat loss in the pigsty, reduce energy consumption, and also help maintain a stable temperature in the pigsty.
[0038] The width of the precast concrete slabs is 600mm or 800mm. Roof truss 1 is set on the top of the main structure, and a light steel frame is used with a pitched roof covered with color steel plates.
[0039] A construction method for a fully prefabricated two-story pig farm building, mainly including the following steps: Step 1, Factory Prefabrication: According to the design requirements, prefabricate the main structure, roof truss 1, enclosure 4, feeding partition wall, slatted floor, fully prefabricated ribbed plate and other components in the factory to ensure the quality and precision of the prefabricated components and improve construction efficiency and building quality. Step 2: On-site measurement and positioning: Conduct on-site measurement and positioning according to the drawings to determine the specific location of the main structure and ensure the accuracy and stability of the building; Step 3: Foundation Construction: Excavate earthwork according to the drawings, construct the independent foundation for the main structure, and pre-embed pre-reserved components to provide a solid foundation for the subsequent installation of the main structure. To facilitate the installation of precast columns, the foundation of this invention has pre-reserved vertical reinforcing bars, which are welded to the longitudinal reinforcing bars extending from the bottom of the precast columns. Simultaneously, square steel pipes are pre-reserved at the bottom of the columns according to the cast-in-place height, which not only improves the connection performance at the bottom of the columns but also facilitates the determination of the vertical positioning of the precast column installation. In the connection area between the precast beams and precast columns on the first floor, this is achieved by setting corbels on top of the foundation. The precast beams are directly placed on the corbels to achieve a hinged connection, making construction convenient and quick. Step 4: Main Structure Installation: Fix the prefabricated main structure to the main foundation to ensure accuracy and stability. The main structure can be installed using hoisting, assembly, and welding techniques to improve construction efficiency and quality. Specifically, the overall frame is connected to the prefabricated beams by installing corbels on the top of the prefabricated columns. In the ground floor of the livestock area, columns and corbels at the base of the columns are used as supports for the prefabricated beams on the manure pit floor slab. On the second floor, columns are erected on the beams of the manure pit floor slab as supports for the prefabricated beams. No in-situ casting connection is required at the supports, making construction simple and quick. The prefabricated slatted floor at the livestock area elevation is placed on top of the prefabricated beams in a simply supported one-way slab configuration, with a 20mm joint left between the prefabricated slabs at the supports for sealing. Step 5: The construction process of the light steel roof truss focuses on lightweight, high-strength, and prefabricated construction. First, material pretreatment is carried out, with cold-formed thin-walled steel components prefabricated in the factory to ensure dimensional accuracy. On-site, a modular assembly method is adopted. First, the anchor bolts at the bottom of the square steel tube columns are positioned and the embedded parts are corrected. Then, professional technicians install the main and secondary trusses according to the design drawings, using high-strength bolts or self-tapping screws for node connections, and a temporary support system to ensure structural stability. Corrosion protection is implemented simultaneously during construction, with galvanized coating or fire-retardant and anti-corrosion coatings to enhance durability. Finally, verticality and horizontality are checked using a laser calibrator, and non-destructive testing of weld points and overall load testing are completed to ensure that the roof truss system meets the requirements of seismic resistance, wind resistance, and load-bearing capacity specifications, achieving the goal of efficient and environmentally friendly industrialized construction. Step 6: Installation of External Enclosure 4: Install external enclosure 4 to form a semi-enclosed pigsty, which provides insulation, heat insulation, wind protection, and rain protection, providing a good growth environment for the pigs. Step 7: Installation of internal facilities: Install internal facilities such as partition walls and slatted floors in the pigsty to ensure that the layout of the pigsty is reasonable and the functions are complete. Step 8: Installation of breeding equipment: Install breeding equipment such as feeding modules, constant temperature and humidity ventilation equipment, lighting equipment, and Internet of Things control system to realize automated and intelligent management of the breeding process; Step Nine, System Debugging and Acceptance: Conduct a comprehensive debugging and acceptance test on the entire building system and its equipment to ensure that all functions operate normally and meet the design requirements and usage standards before it can be put into use.
