Fabricated building

Abstract

The invention relates to a fabricated building and an assembling method thereof, and belongs to the technical field of fabricated buildings. The fabricated building comprises a rectangular frame bodyformed by plugging a stand column, a top beam and a bottom beam, the frame body is installed on a base, wall boards are installed at the periphery of the frame body, a roof board is installed at the top through a roof connecting mechanism, a building base plate is arranged on the bottom, the wall boards and the roof board are each formed by assembling a plurality of heat preservation decoration integrated wall board units through rabbets, and the roof top board is formed by sequentially assembling and connecting a plurality of heat preservation decorative integrated roof top plate units end toend. No decoration needs to be added, the weather resistance is good, the heat preservation performance is excellent, the sealing performance is good, the weight is low, assembling is convenient, thewaterproof effect is good, the safety coefficient is high, and the on-site construction and transportation cost can be greatly lowered.

Description

Technical field [0001] The invention relates to a prefabricated house and an assembly method thereof, and belongs to the technical field of prefabricated houses. Background technique [0002] Prefabricated houses are residential buildings constructed by industrialized production methods. Some or all of the residential components are prefabricated in the factory and then transported to the construction site. The components are assembled through reliable connections. The existing prefabricated houses are mainly composed of house frames, wall panels and roofs. The existing prefabricated houses mainly have the following defects: [0003] 1. The wallboard has poor weather resistance. At present, most wallboards on the market are composed of metal layer composite insulation materials. The metal structure is easy to rust and has poor weather resistance; [0004] 2. Poor thermal insulation performance, poor thermal insulation of the metal layer of the wall panel, and cold bridges indoors; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The wall panels have poor weather resistance. Most of the wall panels currently on the market are metal layer composite insulation material structures. The metal structure is easy to rust and has poor weather resistance;

[0004] 2. The thermal insulation performance is poor, the metal layer of the wallboard has poor thermal insulation performance, and there is a cold bridge phenomenon in the room;

[0005] 3. The weight is heavy, and the metal layer of the wallboard is heavy, which affects transportation and handling;

[0006] 4. The sealing performance is poor. Most of the wallboard connections on the market are in the form of linear simple male and female notches, with large gaps and poor sealing performance;

[0007] 5. At present, the wall panels and roof panels on the market have a single combination of layers, complex processing and compounding processes, additional decorative materials are installed, the performance of the adhesive material used for installation is unstable, and the screws used for installation will damage the airtightness of the house;

[0008] 6. The roof slabs currently on the market need a secondary waterproof layer on the outside after being installed on site. The construction cost is high, the waterproof performance is poor, and structural waterproofing cannot be achieved;

[0009] 7. The load-bearing capacity of the roof slab is poor. At present, the load-bearing capacity of the roof slab on the market needs to rely on the external rigid frame of the roof. Its own load-bearing capacity is poor, and the external rigid frame affects the appearance;

[0010] 8. At present, most of the frames on the market are steel structure trusses, which require some welding work, and the on-site installation process is complicated;

[0011] 9. There is a cold bridge phenomenon, the frame structure is separated from the wall and other maintenance structures, the thermal insulation performance is poor, and the cold bridge phenomenon is prone to occur;

[0012] 10. The weather resistance is poor, the steel structure is easy to rust, and the service life is low

[0013] 11. The roof is mostly a flat structure, which is easy to accumulate rainwater, causing water leakage in the house, and the waterproof effect is poor;

[0014] 12. The connection between the roof and the roof beam of the house is not firm, the roof and the roof beam of the house are easy to separate, and the safety factor is low;

[0015] 13. The roof is heavy and must be installed by lifting equipment, and the on-site construction cost and transportation cost are high
