Prefabricated Mould for House Floor Slabs
The prefabricated mould for house floor slabs is a key industrial equipment used for producing prefabricated concrete floor slabs, achieving concrete forming through a specific structure and directly influencing the geometric accuracy and production efficiency of the components. The following provides an explanation from four aspects: technical principles, structural composition, application scenarios, and development trends:
1. Technical Principles and Core Functions
The prefabricated component mould uses a steel mould as its main structure and employs wet demoulding technology to achieve non-destructive separation of uncured components. This technology enhances movement efficiency through wing-shaped torsion spring positioning and oil lubrication in sliding slots. The modular design of chamfering forming tools reduces mould modification costs and improves production line adaptability, while new positioning systems such as magnetic box-fixed side moulds further optimize component accuracy. Mould manufacturing must adhere to stiffness calculation specifications, with support structures selected from section steel or steel plates. The design value of the bearing capacity must meet specification requirements to ensure no deformation occurs during repeated use.
2. Structural Composition and Standardized Design
A typical mould consists of standardized components including a bottom mould, side moulds, and end moulds, facilitating quick assembly and disassembly. Moulds with large bottom plates have higher reuse rates, reducing production costs. Finished products must be coated with machine oil for rust prevention during storage and undergo structural inspections when the number of turnovers is high to ensure safety. Current technological development focuses on the composite application of automated demoulding devices and lightweight materials. For example, glass-reinforced plastic and aluminium alloy composites reduce weight by over 30% compared to traditional steel moulds while maintaining the same stiffness, significantly increasing the number of turnovers.
3. Application Scenarios and Component Types
Moulds are primarily used for producing six types of standard components, such as composite floor slabs and balcony slabs, covering residential and commercial buildings. For example, composite slab moulds must meet specifications for a span of 4.2 meters and a thickness of 120-150 mm, while the live load rating must comply with standards for residential Grade I slabs (1 kN/m²) or Grade II slabs (2 kN/m²). Due to special geological conditions in the southwest region, a minimum of Grade IV slabs (4 kN/m²) is specified, imposing higher requirements on the mould's bearing capacity.
4. Development Trends and Innovation Directions
Mould design is evolving towards modularity and combinability, reducing modification costs through structural optimization. For example, mobile moulds can adapt to different production line requirements, while assembled moulds achieve quick replacement through standardized components. Additionally, material innovation is a key breakthrough. The composite application of aluminium alloys and glass-reinforced plastics not only reduces mould weight but also extends service life, providing a more efficient solution for building industrialization.
