Design Specifications for Prefabricated Panel Factory Buildings
The design specifications for prefabricated panel factory buildings cover aspects such as design standards, structural systems, material requirements, design principles, and construction and acceptance. Details are as follows:
Design Standards: The design of prefabricated panel buildings must meet relevant national standards, such as the 'Code for Fire Protection Design of Buildings', 'General Code for Design of Buildings', and 'Code for Design of Concrete Structures in Building Structures'. These standards set basic requirements for building design from the perspectives of fire protection, general design, and structural safety. For assembled shear wall residential buildings, reference can be made to the Beijing local standard 'Design Code for Assembled Shear Wall Residential Buildings' (db11/t 970—2013). This code provides detailed regulations on basic requirements, building modular coordination, planar design, prefabricated wall design, and other aspects, offering specific guidance for the design of certain types of prefabricated panel buildings.
Structural Systems: The structural system of assembled rural houses (similar to prefabricated panel buildings) needs to be clearly defined, such as assembled concrete shear wall structural systems. Different structural systems have their unique design and construction specifications. During the design process, it is necessary to reasonably select a structural system based on factors such as the building's purpose, scale, and geological conditions, and strictly follow the corresponding specifications for design and construction to ensure the safety and stability of the structure.
Material Requirements: During the design process, it is advisable to adapt to local conditions and use locally available materials, giving priority to green and economical building materials or recyclable building materials. This not only reduces construction costs but also minimizes the impact on the environment. At the same time, the use of high-energy-consuming and excessively polluting materials is prohibited to meet the requirements of sustainable development.
Design Principles: Respect for usage needs should be prioritized, taking into account local climate, topography, and traditional architectural characteristics to meet modern functional requirements. For example, appropriate consideration should be given to aging-friendly design, and barrier-free ramps should be installed at entrances and exits to facilitate the travel of the elderly. The planar layout and facade design should facilitate winter sunshine and summer ventilation, and a north-south orientation should be preferred to improve building comfort and energy efficiency.
Construction and Acceptance: The production and installation of prefabricated panels must comply with relevant construction specifications and safety regulations. Construction personnel should possess the corresponding professional skills and qualifications to ensure safety and construction quality during the installation process. Prefabricated panels should undergo strict acceptance procedures before leaving the factory and before use, including appearance inspection, dimension measurement, and performance testing. Only prefabricated panels that pass the acceptance can be used in building construction.
