Description

A four-layer wooden floor

technical field

The utility model relates to the field of wood floors, in particular to a wood floor with a four-layer structure.

Background technique

Wooden floor refers to the floor made of wood. Wooden flooring produced in China is mainly divided into six categories: solid wood flooring, laminate flooring, solid wood composite flooring, multi-layer composite flooring, bamboo flooring and cork flooring, as well as the emerging wood-plastic flooring. . The surface layer of solid wood composite flooring is high-quality precious wood, which retains the beautiful and natural characteristics of solid wood flooring. In order to prevent cracking and other phenomena in the dry heating season, the surface of most wood composite flooring will use precious wood species veneer. But this also makes the price of solid wood flooring, which is not cheap, more expensive; at the same time, the cost of replacement and maintenance has also increased. Some manufacturers can only settle for the next best thing, and the price of planks has dropped, but the problems of deformation, warping and cracking of the surface wood of the wooden floor are more serious.

To sum up, we propose a four-layer structure wooden floor to solve the above problems.
