AI Technical Summary
Existing foam boards have poor stability at the joints in long, flat surface covering scenarios. They are prone to loosening or separation due to vibration or compression, affecting the integrity of the overall structure.
It adopts a snap-fit design, which uses the cooperation of plug-in components and plug-in parts, and the combination of limit posts, docking plates, screws and locking bolts to form a multi-dimensional fixation with the semi-circular studs and diamond nuts at the corners of the frame, which enhances the structural strength of the splicing.
It significantly improves the vibration and compression resistance of the splice joints, prevents loosening or separation, ensures the stability and integrity of the overall structure, and facilitates construction and maintenance.
