Wood floor

Abstract

The invention relates to a wood floor. After the existing wood floor is used for a period, one surface, which contacts with the ground, of the wood floor is bent because of moisture absorption expansion, thus the use effect is influenced. The lower surface of the wood floor provided by the invention is provided with a plurality of deep grooves the depth of which accounts for 1 / 5-1 / 3 of the thickness of the wood floor, and the expansion stress of the wood floor after moisture absorption can be dispersed and offset, thus the wood floor provided by the invention can not bend from the ground because of moisture absorption expansion after being used for a long term.

Description

technical field [0001] The invention relates to a building material, in particular to a wooden floor. Background technique [0002] Wooden floor is a commonly used home decoration material, but after the existing wooden floor is used for a period of time after being laid, the side of the wooden floor often appears to be lifted from the ground ( figure 1 ), this is because wooden materials are susceptible to moisture, and the wooden floor laid on the ground is easy to absorb moisture after a period of use. However, due to the air flow and dryness, the shape does not change, so the side of the wooden floor is tilted upwards, which affects the use. In order to overcome the defect of wooden floor moisture absorption and expansion, some people have improved the structure of wooden floor, figure 2 It is a schematic diagram of the cross-section structure of the wooden floor in the prior art.

[0002] Wooden floor is a commonly used home decoration material, but after the existing wooden floor is used for a period of time after being laid, the side of the wooden floor often appears to be lifted from the ground ( figure 1 ), this is because wooden materials are susceptible to moisture, and the wooden floor laid on the ground is easy to absorb moisture after a period of use.

In order to overcome the defect of wooden floor moisture absorption and expansion, some people have improved the structure of wooden floor, figure 2 It is a schematic diagram of the cross-section structure of the wooden floor in the prior art. The wooden floor (1') is provided with multiple sets of parallel grooves (10') on the side in contact with the ground, and the depth of the grooves (10') is relatively shallow , and its ratio to the thickness of the wooden floor (1') is usually between 1 / 15 and 1 / 18. When the wooden floor (1') absorbs moisture from the ground, the existence of the groove (10') can to a certain extent Relieve the phenomenon of side warping of the wooden floor (1'), but the effect is very small, and it cannot meet the use requirements
