Design Drawings for Prefabricated Panel Factory Buildings
Currently, there is no complete publicly available information specifically targeting the design drawings for prefabricated panel factory buildings. However, two types of related drawings can be provided for reference, while noting the limitations of prefabricated panels in building construction.
The first type is detailed processing drawings for prefabricated modular mobile houses. These drawings include 21 detailed design elements, with a core structure consisting of a steel frame paired with thermal and acoustic insulation composite walls. The design logic involves overall prefabrication in the factory, achieving standardized component manufacturing through modular production. The houses are fully decorated upon leaving the factory and only require on-site hoisting and placement for immediate use, making them suitable for temporary business premises, emergency housing, and other scenarios. This design enhances overall stability through the steel frame and addresses the poor sound insulation and thermal insulation performance of traditional prefabricated panels with composite walls. However, due to the temporary nature of mobile houses, their design standards differ from those of fixed buildings and cannot be directly applied to long-term factory construction.
The second type is design drawings for prefabricated components of a certain building. This drawing system is more complex, including a general description of prefabricated component design, floor plans, node waterproofing details, connection details, formwork drawings, and internal partition board layout drawings. The design focuses on resolving the coordination issues between prefabricated components and the main structure: optimizing leakage risks through node waterproofing details, ensuring structural integrity with connection details, standardizing component production dimensions with formwork drawings, and conducting modular design for non-load-bearing parts with internal partition board layout drawings. These drawings are closer to the design approach of modern prefabricated buildings but should be noted that they are applicable to building construction. If used for factories, parameters such as span and load-bearing capacity need to be adjusted according to the functional requirements.
It is particularly important to emphasize that prefabricated panels have been explicitly prohibited by the state for use in commercial housing construction due to issues such as poor seismic performance, short service life, and susceptibility to leakage and cracking. This restriction also applies to factory buildings with high structural safety requirements. If designing a factory building, it is recommended to prioritize cast-in-place concrete structures or prefabricated concrete components that comply with national standards to avoid safety hazards caused by improper material selection. If prefabricated components must be used for special needs, it is essential to strictly follow specifications such as the 'Technical Standard for Prefabricated Concrete Buildings', conduct structural safety calculations through professional institutions, and ensure that component quality complies with standards such as GB/T 51231-2016.
