Prefabricated Components on Property Certificate
The property certificate does not directly indicate whether a house is made of prefabricated components, but a preliminary judgment can be made based on the house's structural type. Property certificates for prefabricated panel houses typically state 'brick-concrete structure'. Here is a detailed explanation:
Association Between Property Certificate and House Structural Type
The property certificate is a legal document proving house ownership, primarily recording basic information about the house, such as its location, area, purpose, and owner. In terms of the house's structural type, the property certificate will clearly indicate it, with common types including brick-concrete structure, frame structure, and steel structure. Among them, the brick-concrete structure is a relatively traditional form of building structure that combines the load-bearing characteristics of brick walls with the stress-bearing features of concrete floor slabs, beams, and other components.
Relationship Between Prefabricated Panel Houses and Brick-Concrete Structure
Prefabricated panels were a commonly used floor slab form in early 20th-century construction. They were processed and molded into modules or panels of specific sizes and shapes using concrete in a prefabrication yard through specific molds and processes, and then transported to the construction site for installation. Both prefabricated panels and cast-in-place panels are floor slab forms in composite or brick-concrete structures. In houses using prefabricated panels as floor slabs, the overall structure still relies on brick walls as the main load-bearing components, with prefabricated panels serving as just one construction method for the floor slab part. Therefore, such houses are typically labeled as brick-concrete structures on property certificates.
Reasons Why the Property Certificate Alone Cannot Determine the Use of Prefabricated Components
Although the property certificate indicates a brick-concrete structure, it cannot be concluded that the house definitely uses prefabricated panels. This is because, in addition to prefabricated panels, the floor slabs in brick-concrete structures may also be cast-in-place panels. Cast-in-place panels are formed by directly supporting formwork, binding reinforcement, and pouring concrete on the construction site, differing from prefabricated panels in construction process and performance characteristics. To accurately determine whether a house uses prefabricated components, it is necessary to refer to materials such as the house's construction year, design drawings, and construction records, or conduct on-site inspections through professional house inspection agencies.
