Description

Technical Field

[0001] The utility model relates to the technical field of flooring, and more specifically to a multi-layer reinforced solid wood flooring. Background Art

[0002] In the field of floor materials, solid wood flooring is favored by consumers for its natural, environmentally friendly and high-end quality. However, single-layer solid wood flooring also has some inherent disadvantages, such as poor stability, easy to be affected by moisture and deformation, and high price. In order to overcome these disadvantages, a variety of alternative products have appeared on the market, among which multi-layer solid wood flooring has gradually attracted attention due to its unique structure and performance.

[0003] At present, the solid wood floors on the market usually simply insert the first protrusion into the limit groove to achieve the purpose of splicing multiple solid wood floors, but there is no fixing effect. When used for a long time, due to the influence of external factors, the floor will move, so that the gap between the floors will become larger, affecting user use.

[0004] Moreover, the multi-layer solid wood floors on the market simply fix each layer of solid wood floors together by gluing, and the structure is not tight, so it is easy for the upper and lower layers to shift. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a multi-layer laminate solid wood floor, which achieves the technical purpose of improving the connection stability between floor panels by adopting limit blocks and protrusions.

[0007] The utility model is further configured as follows: each of the limit grooves is provided with two relatively arranged limit blocks, each of the limit blocks is provided with two springs at the bottom, and the bottom of the limit groove is provided with two relatively arranged accommodating grooves, one end of each spring is fixedly connected to the bottom of the accommodating groove, and the other end is fixedly connected to the limit block, the limit block can be completely squeezed into the accommodating groove, the inclination angle of the spring is consistent with the inclination angle of the inclined surface of the limit groove, each of the limit blocks is provided with protrusions on both sides, and four sliding grooves are provided in the limit groove, and the protrusions are slidably connected to the sliding grooves.

[0008] The utility model is further configured as follows: the cross section of the first protrusion is a trapezoid, the cross section of the limiting groove is also a trapezoid, and the cross section of the limiting block is a triangle.

[0009] The utility model is further configured as follows: the top surface and the bottom surface of the moisture-proof layer are both provided with a plurality of second protrusions, the substrate layer and the bottom surface facing the moisture-proof layer are respectively provided with grooves, the second protrusions correspond to the grooves one by one, and the second protrusions can be inserted into the grooves.

[0010] The utility model is further configured as follows: the base material layer is made of pine wood board, the moisture-proof layer is made of polyethylene material, and the bottom layer is made of poplar wood board.

[0011] The utility model is further configured as follows: the thickness of the floor body is 3-5 cm, and the thickness of the substrate layer is 1-2 cm.

[0012] In summary, the utility model has the following beneficial effects: by arranging a limiting plate and a spring in the limiting groove, the first step-shaped protrusion can be fixedly connected with the limiting groove after being inserted into the limiting groove, which is easy to operate and makes the connection between two adjacent floors tighter.

The bottom layer 6 is made of poplar wood boards, which are relatively low in cost and have good stability and durability. The bottom layer 6 uses these woods to maintain the overall stability and structural strength of the floor; a plurality of second protrusions 14 are provided on the top and bottom surfaces of the moisture-proof layer 5, and grooves are respectively provided on the sides of the substrate layer 4 and the bottom layer 6 facing the moisture-proof layer 5. The second protrusions 14 correspond to the grooves one by one, and the second protrusions 14 can be inserted into the grooves and fit tightly with the grooves. The thickness of the floor body 1 is 3-5cm, the thickness of the substrate layer 4 is 1-2cm, and the three material layers of the substrate layer 4, the moisture-proof layer 5 and the bottom layer 6 account for 80% of the total thickness. The second protrusions 14 are mutually engaged with the grooves, which enhances the tightness of the connection between these material boards.
