Description

Technical Field

[0001] This application relates to the field of ground or floor layer technology composed of several similar components, and specifically to a geothermal impregnated paper laminate solid wood composite floor. Background Technology

[0002] Winters in northern regions are long and cold, so wooden flooring can be used for insulation to improve home comfort. Northern regions often use centralized heating, including underfloor heating, during winter. Underfloor heating results in low air humidity. To increase indoor humidity, some families use humidifiers while the underfloor heating is on to maintain a comfortable environment. However, this can cause the flooring to become damp, leading to warping and swelling due to excessive moisture absorption. Summary of the Invention

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a geothermal-resistant impregnated paper-laminated solid wood composite flooring that reduces bulging of wooden floors caused by underfloor heating. The technical solution adopted includes:

[0004] A geothermal-resistant impregnated paper laminate solid wood composite flooring includes a strip-shaped flooring body, comprising impregnated paper, high-density fiberboard, plywood, and a single baseboard arranged sequentially from top to bottom. The plywood comprises multiple layers of wood boards arranged sequentially from top to bottom, with the topmost layer of the multiple layers of wood boards being the first layer. The conduits of the first layer of wood boards are distributed along the length of the wood flooring, and the conduit holes of the first layer of wood boards face the wide side of the flooring body.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the guide tubes of the multi-layer wooden board are distributed alternately from top to bottom.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a wax layer is provided on each of the four sides of the floor body.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the plywood is provided with male tenons and female tenons that cooperate with each other on the side of the corresponding width direction. When the male tenon and female tenon are engaged with each other, the first layer of wood boards of the male tenon and female tenon of two adjacent floor bodies are bonded to each other.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: when the male tenon and the female tenon are engaged with each other, there is a gap between the remaining layers of wood boards of two adjacent floor bodies except for the first layer of wood boards.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the male tenon includes an upper male tenon surface, a tongue, and a lower male tenon surface distributed from top to bottom, and a limiting block is provided at the lower end of the tongue;

[0010] The tenon includes an upper tenon surface, a slot, and a lower tenon surface distributed from top to bottom, and the slot is provided with a limiting groove that matches the limiting block;

[0011] The thickness of the upper male tenon and upper female tenon is matched with the thickness of the first layer of wood.

[0012] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the first layer of wood board is provided with chamfered R-angles on both sides of the corresponding length direction, so that when the male tenon and the female tenon are mortised and tenoned together, there is a gap on the side of the two adjacent first layer wood boards in the corresponding length direction.

[0013] The beneficial effects of this utility model are:

[0014] The plywood is made of multiple layers of wood boards glued together. The top layer of wood boards is the first layer. Since the ducts of the first layer of wood boards are distributed along the length of the wood flooring and the duct holes face the wide edge of the flooring body, when the moisture content in the air is high, the exposed area of ​​the duct holes in the first layer of wood boards can be reduced, thus reducing the water absorption of the plywood. This controls the water absorption of the wood flooring when the air humidity is high and reduces the bulging phenomenon of the wood flooring. Attached Figure Description

[0023] Reference Figure 1-3 This application proposes an embodiment of the geothermal impregnated paper laminate solid wood composite flooring, which includes a strip-shaped floor body 10, comprising impregnated paper 20, high-density fiberboard 30, plywood 40 and single bottom board 70 arranged sequentially from top to bottom. The plywood 40 comprises multiple layers of wood boards arranged sequentially from top to bottom, and the topmost layer of wood boards is the first layer of wood board 41. The conduits of the first layer of wood board 41 are distributed along the length of the wood flooring, and the conduits of the first layer of wood board 41 face the wide side of the floor body 10.

[0024] Referring to the attached drawings, the plywood 40 is made of multiple layers of wood boards glued together. The top layer of wood boards is the first layer 41. Since the ducts of the first layer 41 are distributed along the length of the wood flooring and the duct holes face the wide edge of the flooring body 10, when the moisture content in the air is high, the exposed area of ​​the duct holes in the first layer 41 can be reduced, thus reducing the water absorption of the plywood 40. This controls the water absorption of the wood flooring when the air humidity is high and reduces the bulging phenomenon of the wood flooring.

[0025] In this embodiment, the conduits of the multi-layer wood board are distributed alternately from top to bottom, which helps to ensure the structural stability of the plywood 40.

[0026] Based on the above, in this embodiment, a wax layer is also provided on the four sides of the floor body 10. The wax layer can form a sealing layer around the high-density fiberboard 30, plywood 40 and single bottom board 70, further reducing the water absorption of the floor body 10.

[0027] Furthermore, the plywood 40 has male tenons 50 and female tenons 60 that cooperate with each other on the side corresponding to the width direction. When the male tenon 50 and female tenon 60 are engaged with each other, the first layer of wood boards 41 of the male tenons 50 and female tenons 60 of the two adjacent floor bodies 10 are bonded to each other.

[0028] Because the first layer of wood panels 41 has holes distributed on both sides of the width of the plywood 40, after the floor is laid, the first layer of wood panels 41 of the adjacent two floor panels 10 are bonded together by the male tenon 50 and female tenon 60 after the floor body 10 is mortised and tenoned together, which improves the sealing effect between the first layer of wood panels 41. When the moisture content in the air is high, it prevents moisture in the air from entering the plywood 40 through the gaps between the plywood 40.

[0029] Meanwhile, there are gaps between the remaining layers of wood boards to provide expansion gaps for the floor body 10.

[0030] Specifically, the tenon 50 includes an upper tenon surface 51, a tongue 52, and a lower tenon surface 53 distributed from top to bottom, and a limiting block 54 is provided at the lower end of the tongue 52;

[0031] The tenon 60 includes an upper tenon surface 61, a slot 62, and a lower tenon surface 63 distributed from top to bottom. The slot 62 is provided with a limiting groove 64 that matches the limiting block 54.

[0032] The thickness of the upper male tenon surface 51 and the upper female tenon surface 61 matches the thickness of the first layer of wood board 41. When the male tenon 50 and the female tenon 60 are mortised together, the upper male tenon surface 51 and the upper female tenon surface 61 fit together. The tongue piece 52 is inserted into the slot 62, and its upper end abuts against the inner top wall of the slot 62.

[0033] Based on the above, through the structure of the male tenon 50 and female tenon 60, the first layer of wood board 41 is provided with chamfered R-angle 42 on both sides of the corresponding length direction, so that when the male tenon 50 and female tenon 60 are mortised together, there is a gap between the two adjacent first layer wood boards 41 on the sides of the corresponding length direction. Since the first layer of wood board 41 does not have pipe holes on both sides of the length direction of the floor body 10, when the tongue 52 is inserted into the slot 62 and abuts against the inner top wall of the slot 62, the abutting time of the two provides space for the expansion of the first layer of wood board 41, preventing moisture from entering between the other layers of wood board.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
