[0050] (1) The building structure uses standardized connecting components (including full-length clips, wall panel connecting components, purlin connecting components and purlin brackets) to achieve efficient assembly between various components. The connection method combines structural simplicity with assembly efficiency. The types and structural forms of connecting components are integrated and optimized to achieve unification and simplification, forming a standardized connection system. The wall panel components adopt a standardized prefabrication model, based on a simplified processing process, adapted to the needs of industrialized batch processing and production, and effectively reduce the overall cost. Through the collaborative operation mode of factory prefabrication and on-site modular rapid assembly, the construction cost is significantly reduced while the construction efficiency is improved, achieving the dual technical effects of resource intensiveness and construction efficiency.

[0051] (2) The wall panels are rigidly connected to the precast concrete foundation plate using bottom embedded fixing devices (full-length clips). Adjacent wall panel units are assembled using standardized connection components, which include one or a combination of flat connectors and U-shaped connectors. This constructs a three-dimensional spatial constraint system to achieve a self-stabilizing structure for the wall panels, abandons the traditional temporary fixing method of diagonal braces, significantly improves the efficiency of prefabricated construction and ensures the accuracy of structural installation. Compared with conventional construction processes, the construction period can be shortened by 25% to 40%.

[0052] (3) The vertical mold casting process is adopted in the manufacturing of wall panels to realize the simultaneous molding of multiple components in the same batch, which significantly reduces the occupation of production space by mold equipment, effectively improves space utilization, and thus greatly improves production efficiency.

[0053] (4) The house adopts a combination of factory prefabrication and on-site spraying, which can effectively solve the common problem of cracks in the wall joints, effectively ensure the integrity of the wall, and fundamentally avoid the problem of wall cracks; the protective layer is tightly combined with the wall panel, fundamentally eliminating quality defects such as hollowing and falling off, and reducing the maintenance cost of the building throughout its life cycle by 40~60%.

[0133] The beneficial effects of the construction method of the single-layer light-weight plate-type structure house of the present invention are:

[0134] (1) The building structure uses standardized connecting components (including full-length clips, wall panel connecting components, purlin connecting components and purlin brackets) to achieve efficient assembly between various components. The connection method combines structural simplicity with assembly efficiency. The types and structural forms of connecting components are integrated and optimized to achieve unification and simplification, forming a standardized connection system. The wall panel components adopt a standardized prefabrication model, based on a simplified processing process, adapted to the needs of industrialized batch processing and production, and effectively reduce the overall cost. Through the collaborative operation mode of factory prefabrication and on-site modular rapid assembly, the construction cost is significantly reduced while the construction efficiency is improved, achieving the dual technical effects of resource intensiveness and construction efficiency.

[0135] (2) The wall panels are rigidly connected to the precast concrete foundation plate using bottom embedded fixing devices (full-length clips). Adjacent wall panel units are assembled using standardized connection components, which include one or a combination of flat connectors and U-shaped connectors. This constructs a three-dimensional spatial constraint system to achieve a self-stabilizing structure for the wall panels, abandons the traditional temporary fixing method of diagonal braces, significantly improves the efficiency of prefabricated construction and ensures the accuracy of structural installation. Compared with conventional construction processes, the construction period can be shortened by 25% to 40%.

[0136] (3) The vertical mold casting process is adopted in the manufacturing of wall panels to realize the simultaneous molding of multiple components in the same batch, which significantly reduces the occupation of production space by mold equipment, effectively improves space utilization, and thus greatly improves production efficiency.

[0137] (4) The house adopts a combination of factory prefabrication and on-site spraying, which can effectively solve the common problem of cracks in the wall joints, effectively ensure the integrity of the wall, and fundamentally avoid the problem of wall cracks; the protective layer is tightly combined with the wall panel, fundamentally eliminating quality defects such as hollowing and falling off, and reducing the maintenance cost of the building throughout its life cycle by 40~60%.
