Description

Technical Field

[0001] The present invention relates to the technical field of breeding buildings, in particular to a steel structure prefabricated pig house for rapid construction and its construction method. Background Art

[0002] In recent years, prefabricated buildings and industrial modernization have developed rapidly in China. The State Council has issued the "Guiding Opinions on Vigorously Developing Prefabricated Buildings", further clarifying that in the future, prefabricated building technologies should be actively promoted, and it is hoped that within about 10 years, the proportion of prefabricated buildings in newly built buildings will reach 30%. The advantages of prefabricated buildings are fast construction speed, little restriction by climate conditions, labor saving and improved building quality.

[0003] With the rapid development of modern aquaculture, modern heat-insulating and energy-saving pig houses have replaced traditional semi-open pig houses. Modern intensive aquaculture technology requires the installation of an environmental control system, a ventilation and air exchange system, a feed supply system, and a lighting system, etc. in the heat-insulating and energy-saving pig house. At the same time, after ammonia and hydrogen sulfide formed by pig excrement are combined with water, they will form a chemical electrolytic reaction with the metal surface, and the metal components will be quickly corroded. Ordinary color steel pig houses will be scrapped in only about 3 - 5 years, and a ceiling system with heat insulation, flame retardancy, corrosion resistance, and high-pressure flushing resistance needs to be set up. Therefore, using conventional construction techniques to build modern heat-insulating and energy-saving pig houses has a long construction period and unstable quality.

[0004] Existing modular buildings based on container technology are limited by transportation dimensions, have small bays, and cannot meet the space requirements of modern intensive aquaculture. Summary of the Invention

[0005] The purpose of the present invention is to provide a steel structure prefabricated pig house for rapid construction and its construction method, which can significantly improve the construction speed, ensure the construction quality, and reduce the cost.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A rapid construction steel structure prefabricated pigsty, which is assembled by several pigsty units. The pigsty unit includes a prefabricated roof ceiling frame, steel frame columns, supporting beams and truss connectors. The steel frame columns are distributed in a rectangular array. At the upper end of the steel frame column, there is a supporting plate for supporting the prefabricated roof ceiling frame. On the upper side wall of the steel frame column, there is a side connecting plate for locking the supporting beam. The supporting beam spans between adjacent steel frame columns on the left and right sides. The end of the supporting beam is locked and connected to the side connecting plate, and a beam supporting plate is arranged in the middle of the supporting beam. The prefabricated roof ceiling frame is arranged between two parallel supporting beams. Two prefabricated roof ceiling frames are arranged side by side on the same supporting beam. The prefabricated roof ceiling frame is a rectangular frame surrounded by several trusses. At the four corners of the rectangular frame, there are steel short columns. The steel short columns are locked and connected to the supporting plate at the upper end of the steel frame column or supported on the beam supporting plate in the middle of the supporting beam. The truss connector is arranged between two steel short columns on the butt joint side of the prefabricated roof ceiling frame, and it includes two channel-shaped parts with opposite openings and a cross bar connected between the two channel-shaped parts.

[0008] A construction method for a rapid construction steel structure prefabricated pigsty, which includes the following steps: S1. Fix the steel frame columns in a rectangular array. S2. Span the supporting beam between adjacent steel frame columns on the left and right sides, and lock and connect the end of the supporting beam to the side connecting plate on the steel frame column. S3. Place two prefabricated roof ceiling frames side by side between parallel supporting beams. The steel short columns intersecting with the steel frame columns are locked and connected to the supporting plate through the short column bottom plate, and the steel short columns intersecting with the supporting beam are temporarily supported on the beam supporting plate through the short column bottom plate. S4. Install the truss connector between two steel short columns on the butt joint side of the prefabricated roof ceiling frame, and permanently fix the channel-shaped part to the steel short column. S5. Remove the supporting beam to complete the assembly of the pigsty unit. S6. Continue to install pigsty units on the left and right sides of the assembled pigsty unit. Adjacent pigsty units on the left and right are fixed through truss connectors, and the channel-shaped parts of the truss connectors are locked on the steel short columns of adjacent pigsty units. S7. Continue to install pigsty units on the front and back sides of the assembled pigsty unit. Adjacent pigsty units on the front and back are fixed through connecting rods, and the connecting rods are respectively fixed on the extended section suspensions of adjacent pigsty units.

[0009] Compared with the prior art, the advantages of the present invention are as follows:

[0010] 1. Decomposing the prefabricated pigsty unit into a prefabricated roof ceiling frame and steel frame columns can meet the space requirements during the operation and maintenance of the pigsty while meeting the transportation size limitations.

[0011] 2. The prefabricated roof ceiling frame can be produced and processed in the factory. Due to its fixed shape, it can be transported and hoisted as a whole. Since the highly completed prefabricated roof ceiling frame can be prefabricated off-site, it can significantly accelerate the on-site construction speed.

[0012] 3. The steel short columns of the prefabricated roof ceiling frame are arranged to ensure good stability during transportation; at the same time, it can ensure that the completed roof and ceiling in the factory are not easily damaged during transportation.

[0013] 4. The combined application of steel frame columns, supporting beams and truss connectors can achieve a column-free space within twice the transportation width limit in the length direction of the pigsty, which is convenient for the later operation and maintenance management of the pigsty;

[0014] 5. The construction of large pigsties can be achieved by the horizontal combination of prefabricated pigsty units, and the construction cost can be significantly reduced through the mass production of standard module units. BRIEF DESCRIPTION OF THE DRAWINGS
