Sichuan Prefabricated Floor Slab Molds for Houses
Sichuan prefabricated floor slab molds for houses, with steel molds as the main structure, cover various types and feature modular design and wet demolding technology, directly affecting the precision and efficiency of prefabricated components.
1. Mold Types and Applications
In Sichuan, prefabricated floor slab molds for houses are categorized into multiple types based on production needs. Cement house molds are used for the prefabrication of entire house structures, capable of producing large components such as walls and floor slabs. Drainage cover molds and four-hole notch cover molds are designed specifically for drainage systems, producing covers with holes or special shapes to meet drainage requirements in road and residential areas. These molds, through standardized design, can adapt to the production of prefabricated components with different shapes and sizes, covering core components in industrialized construction such as laminated slabs and stairs.
2. Mold Structure and Materials
The core structure of prefabricated component molds consists of standardized components including bottom molds, side molds, and end molds. The bottom mold, serving as the bearing surface, requires high flatness and deformation resistance. Side molds and end molds are fixed with bolts or clips to form a closed pouring space. In terms of materials, steel molds are the mainstream choice, known for their high strength and wear resistance, allowing for thousands of reuses and significantly reducing long-term costs. Some molds have their surfaces sprayed with release agents or coated with special coatings to further reduce adhesion between components and molds.
3. Key Technical Characteristics
- Wet demolding technology: By optimizing mold surface treatment or using chemical release agents, undried concrete components can be separated without damage. This technology avoids edge damage to components caused by traditional violent demolding, improving the finished product rate while reducing mold wear.
- Modular design: Components such as side molds and end molds of the mold can be quickly disassembled and replaced to meet the production needs of components with different specifications. For example, adjusting the height of the side mold allows for the production of floor slabs with different thicknesses, reducing mold modification costs and improving production line adaptability.
4. Impact on Prefabricated Component Production
The precision of molds directly affects the geometric dimensions of prefabricated components. The high rigidity of steel molds ensures that the perpendicularity error of component edges and corners is controlled within ±1mm, meeting the requirements for component splicing precision in prefabricated construction. Additionally, standardized mold components shorten mold change times, increasing daily production capacity by 20%-30% on a single production line, which is crucial for large-scale production in industrialized construction.
