Shanxi Prefabricated Floor Slab Mold for Houses
The prefabricated floor slab mold for houses in Shanxi, represented by the assembled concrete roof panel mold, is a specialized forming tool used for prefabricated or cast-in-place concrete roof panels. The following provides an introduction from the perspectives of mold structure, materials, technical characteristics, and application areas:
Mold Structure: It generally consists of a bottom mold, side molds, end molds, support devices, and fastening devices. The bottom mold is a crucial part for forming the bottom surface of the roof panel, directly determining the shape and dimensional accuracy of the bottom surface. The side molds and end molds are used to form the side and end shapes of the roof panel respectively, ensuring that the overall shape of the roof panel meets the design requirements. For example, the YWB prestressed large-scale roof steel formwork from Zhengzhou Mana Company adopts pin connections and trapezoidal threaded bolt connections. This design makes the mold easy to assemble and disassemble, with high repeated positioning accuracy, greatly improving construction efficiency.
Mold Materials: Commonly used steels include Q235 or Q355 steel plates, with thicknesses typically ranging from 3 to 6mm. Additionally, section steels, angle steels, and channel steels are used as frames to enhance rigidity. Steel molds have advantages such as high strength, high rigidity, and good durability, ensuring the accuracy and stability of the mold during long-term use. Furthermore, aluminum alloy molds are also commonly used. They have advantages such as light weight, corrosion resistance, and good thermal conductivity, facilitating easy handling and installation, and accelerating the concrete setting speed. However, their strength is relatively lower.
Technical Characteristics: The mold has high processing accuracy, ensuring accurate dimensions and a smooth, flat surface of the roof panel, effectively reducing quality issues such as misalignment and honeycombing. The mold forming surface uses a special isolation coating that can be applied once and used multiple times, avoiding the cumbersome process of applying an isolation agent for each forming operation, while also ensuring excellent appearance quality of the components. The mold design is advanced, with a reasonable structure and high rigidity, enabling it to reliably withstand the weight and lateral pressure of the poured concrete, ensuring no leakage during the pouring process.
Application Areas: Concrete roof panel molds are widely used in the roof structures of industrial plants, warehouses, civil buildings, as well as in large-scale venues and bridge ancillary facilities, providing reliable roof structure solutions for various types of buildings.
