Prefabricated houses are increasingly used in various fields due to their convenient assembly and disassembly, as well as their ease of movement and transportation. Currently, most prefabricated corner sections of steel structures require destructive connections to the main structure, directly using self-tapping screws or connecting bolts on the columns, increasing the difficulty of connection and fit. Furthermore, the use of clamps for installation does not allow for adjustment of the facade, making it difficult to control the flatness of the facade. Summary of the Invention

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0027] A prefabricated corner structure includes: a corner module, comprising a column 1 and corner support beams 2 respectively disposed at both ends of the column 1, with fixing members 4 respectively disposed on the corner support beams 2, and fixing members 4 having first strip-shaped adjustment holes; and an external corner piece 3, with adjusting members 5 respectively disposed at both ends of the external corner piece 3, and adjusting members 5 having second strip-shaped adjustment holes; the first strip-shaped adjustment holes and the second strip-shaped adjustment holes are matched one-to-one, and the angle between the first strip-shaped adjustment holes and the second strip-shaped adjustment holes on the same horizontal plane is greater than 0° when they are matched. Preferably, the angle between the first strip-shaped adjustment holes and the second strip-shaped adjustment holes on the same horizontal plane is 90° when they are matched. Through the design of the strip-shaped holes, the relative positions of the fixing members 4 and the corresponding adjusting members 5 can be adjusted, thereby adjusting the relative positions of the corner support beams 2 and the external corner piece 3, and thus adjusting the angle of the outer surface of the external corner piece 3. Specifically, using the upper and lower fixing parts 4 as the reference plane, the upper and lower adjusting parts 5 can be adjusted and positioned according to the direction of the strip holes. This connection structure is not directly connected to the column 1, reducing the risk of facade skewing due to non-vertical adjustment during column 1 fabrication or installation. The planar position of the adjusting parts 5 on both sides of the building corner can be adjusted using a plumb line for overall adjustment, saving construction time and facilitating installation. The entire structure can be connected with screws, achieving 100% prefabrication and over 95% recyclability. Furthermore, this invention achieves standardized design: standardizing the building corner module installation process, providing standardized products and processes through coding, effectively improving design and detailing efficiency; productizing connecting components to meet high-precision mass production in factories, improving production efficiency; simplifying on-site construction, eliminating on-site welding, reducing disassembly and assembly losses, allowing for recyclability, generating no construction waste, and meeting environmental protection requirements; and improving the versatility of building structural components, enabling mass prefabrication in factories, providing integrated design conditions, reducing design and processing cycles, and improving efficiency.

[0028] In an optional embodiment, the corner support beam 2 includes: a square connector, which includes a cross-shaped connecting column 21 and connecting plates 22 respectively disposed at both ends of the cross-shaped connecting column 21; the cross-shaped connecting column 21 is connected to the corresponding fixing member 4, and the column 1 is connected to the corresponding connecting plate 22; and two crossbeams 23 respectively disposed on adjacent sides of the square connector. The square connector serves as the central connection, connecting to each functional component (fixing member 4, column 1, and crossbeam 23). The processing and installation standards of each functional component only need to be referenced to the square connector. That is, when producing a certain functional component, only the square connector needs to be considered, which significantly reduces the difficulty of production and installation compared to the need to consider multiple factors when producing a certain component.

[0029] In an optional embodiment, the fastener 4 includes: a fixing plate 41, which is connected to the cross-shaped connecting column 21; and a first adjusting plate 42, which is disposed on the fixing plate 41 and has a first strip-shaped adjusting hole. The plane of the first adjusting plate 42 is perpendicular to the axis of the column 1.

[0030] In an optional embodiment, multiple first adjusting plates 42 are provided and respectively disposed on the fixed plate 41. Each first adjusting plate 42 is selectively matched with a corresponding adjusting member 5. This allows for a relatively ample selection range in the height of the corner piece 3 relative to the column 1.

[0031] In an optional embodiment, the external corner piece 3 is provided with a mounting strip 31, and mounting holes are provided at both ends of the mounting strip 31. The adjusting piece 5 is provided with a strip-shaped assembly hole, which corresponds to and engages with the mounting hole. A fixing nut 32 can be welded to the inner side of the mounting strip 31 at the corresponding mounting hole. During installation, the screw passes through the strip-shaped assembly hole and engages with the nut 32. The relative position of the strip-shaped assembly hole and the mounting hole can be adjusted according to the direction of the strip-shaped assembly hole, so that the position of the adjusting piece 5 relative to the external corner piece 3 can be adjusted to a certain extent. This achieves adjustment in all three axes, giving the external corner piece 3 higher adjustability and making installation easier.

[0032] In an optional embodiment, the adjusting component 5 includes: an assembly plate 52, on which a strip-shaped assembly hole is provided; and a second adjusting plate 51, which is connected to the assembly plate 52, and on which a second strip-shaped adjusting hole is provided, and the plane of the second adjusting plate 51 is perpendicular to the axis of the column 1.

[0033] In an optional embodiment, a mating plate 53 is provided on the second adjusting plate 51, and the mating plate 53 is fitted to the inner or outer side wall of the corner piece 3. This makes the connection structure between the corner piece 3 and the adjusting piece 5 more stable and less prone to loosening.

[0034] In an optional embodiment, an intermediate fixing block 6 is further included. The intermediate fixing block 6 is located in the middle of the column 1. The two ends of the intermediate fixing block 6 are respectively provided with a locking part 61 and a connecting part 62. The locking part 61 engages with the column 1, and the connecting part 62 connects with the corner piece 3. The intermediate fixing member 4 is fixed to the column 1 and bolted to the corner piece 3. This structure eliminates the need for splicing between the corner piece 3 and the column 1, strengthens the installation of the corner piece 3, increases the stress points of the corner piece 3, and reduces deflection deformation.

[0035] In an optional embodiment, the corner support beam 2 includes a top support beam and a bottom support beam, wherein: the top support beam includes a square connector and a crossbeam 23, the square connector includes a cross-shaped connecting column 21 and connecting plates 22 respectively disposed at both ends of the cross-shaped connecting column 21, the cross-shaped connecting column 21 is connected to the corresponding fixing member 4, the column 1 is connected to the corresponding connecting plate 22, and there are two crossbeams 23 respectively disposed on adjacent sides of the square connector; the bottom support beam is a cement foundation component 8.

[0036] In an optional embodiment, the fixing member 4 includes a top fixing member disposed on the top support beam and a bottom fixing member 7 disposed on the bottom support beam, wherein: the top fixing member includes a fixing plate and a first adjusting plate, the fixing plate is connected to the top support beam, the first adjusting plate is disposed on the fixing plate, the first adjusting plate is provided with a first strip-shaped adjusting hole, and the plane of the first adjusting plate is perpendicular to the axis of the column 1; the bottom fixing member 7 includes an upper mounting plate 71 and a lower mounting plate 72 fixed to each other, the lower mounting plate 72 is used to install the bottom fixing member 7 on the cement foundation member 8, and the upper mounting plate 71 is provided with a first strip-shaped adjusting hole.
