Prefabricated House National Standard Size Atlas
The atlases involving national standard sizes for prefabricated houses mainly include the 'Prefabricated Concrete Shear Wall Exterior Wall Panels' and relevant series of atlases from Sichuan Province. Here is a detailed introduction:

15G365-1 'Prefabricated Concrete Shear Wall Exterior Wall Panels'
This atlas is an important national standard reference document in the field of prefabricated houses, applicable to prefabricated concrete shear wall structure residential buildings in areas with non-seismic design and seismic fortification intensities of 6 to 8 degrees. Its core content revolves around non-composite sandwich insulation exterior wall panels with floor heights of 2800mm, 2900mm, and 3000mm, covering five commonly used planar component types, including exterior walls without openings, exterior walls with window openings, and exterior walls with door openings. The sizes of these components have been standardized to meet the needs of different building layouts. The atlas not only provides basic design drawings such as template drawings and reinforcement drawings but also includes material lists and detailed drawings of connection node structures, offering a complete technical solution that designers can directly select or refer to. For example, in the connection node structure, key parameters such as the anchorage length of steel bars and the scope of concrete pouring are clearly marked to ensure standardization and safety during the construction process.
Sichuan Provincial Series of Atlases for Standard Components of Prefabricated Concrete in Prefabricated Residential Buildings
This series of atlases, issued by Sichuan Province, consists of four sub-atlases: 'Standard Base Plates for Prestressed Concrete Steel Pipe Truss Composite Slabs', 'Standard Base Plates for Composite Slabs in Prefabricated Residential Buildings (Part 1)', 'Standard Base Plates for Composite Slabs in Prefabricated Residential Buildings (Part 2)', and 'Standard Tread Plates for Prefabricated Concrete Stairs in Prefabricated Residential Buildings'. The compilation goal of these atlases is to shorten the drawing conversion cycle by improving standardization, thereby controlling project costs, enhancing production efficiency, and improving construction quality. Taking 'Standard Base Plates for Composite Slabs in Prefabricated Residential Buildings (Part 1)' as an example, the atlas clearly defines key size parameters such as the thickness and span of the composite slabs and specifies the arrangement and spacing of steel bars, providing a unified standard for the production and installation of prefabricated components. This standardized design not only simplifies the construction process but also reduces material waste caused by size discrepancies, aligning with the development concept of green buildings.
The above-mentioned atlases standardize the component sizes of prefabricated houses through standardized design, providing a unified technical basis for the industry and contributing to the large-scale application of prefabricated buildings.
