AI Technical Summary
In existing lightweight prefabricated PC housing structures, the connection between walls, roof and base relies on manual adjustment, which can easily lead to misalignment or gaps, resulting in poor overall structural integrity. Furthermore, the connection method is cumbersome and prone to loosening, affecting safety and transportation costs. Simply thinning the material results in insufficient resistance to lateral forces, making it prone to deformation or tilting.
The mounting blocks in the base groove are precisely fitted with the PC board connecting blocks, and the roof positioning groove is matched with the positioning column. Combined with the triangular support system of the external frame, reinforcing plate and PC board, the elastic locking structure achieves rigid connection and elastic buffer, disperses lateral force and load, and ensures accurate positioning and deformation resistance.
It achieves precise positioning and rigid connection between the wall and the roof, enhancing the overall stability and deformation resistance of the structure, while reducing transportation and construction difficulties, and ensuring the strength and safety of the lightweight design.
