Description

Magnetic self-priming floor and installation method thereof

Technical field

The present application belongs to the field of home building materials, and relates to a magnetic self-priming floor and a method for installing the same.

Background technique

China's wood flooring output and export volume have taken the first place in the world. It plays a pivotal role in the world's floor decoration materials market. However, the growth and improvement of the wood flooring industry has also been accompanied by the emergence of contradictions, especially the knowledge related to wood flooring. The increasing number of international property rights disputes has severely restricted the development of China's wooden flooring industry. For example, wooden flooring is usually fixed to the floor to be paved using wooden flooring locking technology. Wooden flooring locking technology is one of the core technologies of the wooden flooring industry. Technical points that trigger patent disputes.

The core technology of wood floor lock technology is mainly in the hands of Unilin in Belgium and Valinge in Sweden. If Chinese floor companies want to enter the global market smoothly, they must pay high technology patent fees in order to participate in the global floor market competition, which makes The production cost of wooden flooring in China has greatly increased, patent costs accounted for almost 20% of the cost of flooring export enterprises, and the lack of independent intellectual property rights of lock technology has become the biggest technical bottleneck for China's flooring products to enter the international market.

Adopting buckle-free floor connection technology is a bold innovation of flooring technology. At present, such products are rare in the market. For example, CN202755608U discloses a PVC non-locking non-adhesive non-slip floor. The left and right anti-slip film layers and the glass glue filled between the floor and the wall prevent relative movement between the floor and the floor to be paved. In the long-term use process, it is difficult to ensure a tight connection of the floor.

Another alternative floorless solution is to replace the traditionally fixed floor with a lock with a magnetically fixed floor. For example, CN205116626U discloses a magnetic floor. The floor is laid by the attraction of a magnet. In this technology, the floor used is magnetic, and the floor to be paved needs to be iron or concrete ground with iron powder. It also has great limitations in use; CN203271063U discloses a magnetic For the floor, a magnet is provided on the laying base, and a magnetic attraction device is provided on the floor block. The floor block is attracted to the laying base by the attraction of the magnetic attraction device. However, the magnetic floor and the attracted There is no buffer effect in the middle of the magnetic attraction device, which causes a large noise when the floor is laid, and it is easy to be displaced when it is impacted, so it needs to be further improved.

Based on the related technology, it is necessary to provide a magnetic flooring product that does not require slotting and paving and is easy to replace. It solves the problems of traditional magnetic flooring when it is used, such as noise and impact resistance. On this basis, magnetic flooring products are also It should have the advantages of easy installation, firm floor connection, good antistatic and impact resistance.
