Description

Technical Field

[0001] This utility model relates to the field of building decoration materials technology, specifically a magnetic adsorption composite paving stone. Background Technology

[0002] Currently, traditional paving stones are mostly installed using cement bonding or interlocking grooves. Cement bonding is complex to install, has a long drying and curing time, and is difficult to disassemble and replace during later maintenance. Once a part is damaged, a large area needs to be broken up and replaced, resulting in material waste and increased costs. While interlocking grooves are easy to install, the connection stability is limited. After being subjected to external impacts or long-term use, they are prone to loosening and displacement, affecting the overall flatness and aesthetics of the ground. In addition, most paving stone joints lack effective protection, making pedestrians susceptible to bumps and injuries. The joints are also easily damaged by external impacts, affecting the lifespan of the paving stones, especially in high-traffic areas. Some paving stone base layers are not strong enough and are prone to deformation and cracking under heavy pressure or external forces. Weak connections between layers lead to a decline in the overall performance of the paving stones, shortening their service life and increasing maintenance costs. Traditional paving stones have poor anti-slip properties in wet environments, with a low surface friction coefficient, making pedestrians prone to slipping and posing safety hazards, especially in areas such as bathrooms, kitchens, and outdoor roads.

[0003] Therefore, it is necessary to design a magnetic adsorption composite paving stone to solve the problems mentioned above. Utility Model Content
