Abstract
Description
Technical Field
[0001] This utility model relates to a solid wood floor, and more particularly to a heat-insulating solid wood composite floor. Background Technology
[0002] Solid wood flooring is a floor covering material made from natural wood that has been dried and processed. However, solid wood flooring is relatively expensive, and due to the natural characteristics of wood, it is easily affected by temperature and humidity. In humid environments, it is prone to swelling, while in dry environments, it may shrink and deform, resulting in gaps, warping, or cracks, which affects its performance. Maintenance costs are also high, requiring regular waxing and cleaning to maintain its beauty and durability.
[0003] Engineered wood flooring is made by bonding and compressing solid wood and various other materials. It generally consists of a wear layer, a decorative layer, a core layer, and a bottom layer. Currently, multi-layer engineered wood flooring is widely used in the flooring industry due to its good stability, lower solid wood usage, high wear resistance, reduced cost, and ease of maintenance.
[0004] However, engineered wood flooring also has some drawbacks. For example, although it is relatively stable under certain conditions, it is still prone to deformation in extreme environments, such as humid and high-temperature environments. This not only affects its service life but also affects the tightness of the splicing, creating gaps in the splicing. Heat can easily be lost through these gaps, thus affecting the floor's heat insulation performance. Utility Model Content
[0005] The purpose of this invention is to provide a thermally insulated solid wood composite floor. This invention features resistance to deformation and improved thermal insulation performance.
[0006] The technical solution of this utility model is as follows: Thermal insulation solid wood composite flooring, comprising, from bottom to top, a balance layer, a first insulation layer, an adhesive reinforcement layer, a solid wood layer, a second insulation layer, and a wear-resistant layer; the first insulation layer includes heat insulation boards and insulation boards arranged alternately in the horizontal and vertical directions, with a reflective film provided at the joint between the heat insulation boards and insulation boards; one side of the solid wood layer has a splicing groove, and the other side of the solid wood layer has a splicing protrusion matching the splicing groove; the inner bottom surface and inner side surface of the splicing groove are provided with a first elastic strip, the inner top surface of the splicing groove is provided with a locking block, the splicing protrusion is provided with a locking groove corresponding to the locking block, and the locking groove is provided with a second elastic strip.
[0007] In the aforementioned heat-insulating solid wood composite flooring, the outer surfaces of the first elastic strip and the second elastic strip are both arc-shaped, and the interiors of the first elastic strip and the second elastic strip are both provided with cavities.
[0008] In the aforementioned insulated solid wood composite flooring, the insulation board is made of polystyrene board or rock wool board; the heat insulation board is made of vacuum heat insulation board or polystyrene heat insulation board; and the reflective film is made of aluminum foil reflective film.
[0009] In the aforementioned heat-insulating solid wood composite flooring, the bonding reinforcement layer includes a fiberglass mesh, and both the upper and lower layers of the fiberglass mesh are provided with polymer mortar layers.
[0010] In the aforementioned heat-insulating solid wood composite flooring, the bottom of the balance layer is provided with a moisture-proof layer, the interior of the moisture-proof layer is filled with an adsorption layer, and the bottom of the moisture-proof layer is provided with micropores that communicate with the adsorption layer.
[0011] In the aforementioned insulated solid wood composite flooring, the wear-resistant layer is made of aluminum oxide or UV coating.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention uses a first insulation layer to prevent cold air from entering the floor and a second insulation layer to reduce heat loss upwards, forming "two-way insulation" and improving the floor's insulation effect. The first insulation layer combines an insulation board, a heat insulation board, and a reflective film. The insulation board and heat insulation board block heat transfer, effectively preventing indoor heat loss to the floor and the low temperature of the floor from being conducted to the floor. The reflective film conducts heat upwards, thereby reducing indoor heat loss and better retaining heat. Furthermore, the insulation board and heat insulation board are arranged alternately horizontally and vertically, which can improve the floor's resistance to deformation. The reflective film is placed at the joint between the insulation board and the heat insulation board, improving the tightness of the first insulation layer and preventing heat from escaping from the gaps, thereby further improving the insulation effect.
[0014] Adjacent floorboards are joined using splicing grooves and protrusions. These grooves and protrusions are further reinforced with locking blocks and slots to enhance stability. First and second elastic strips with a certain degree of deformation capability are incorporated into the splicing grooves and slots, ensuring a tight fit between the splicing protrusions / locks and the first and second elastic strips during splicing. This results in a more secure connection, preventing damage from compression even during thermal expansion and contraction, reducing gaps and heat loss at the joints, and improving the stability and sealing of the connection, thereby enhancing the floor's insulation performance.
[0015] Therefore, this utility model has the characteristics of anti-deformation and improved thermal insulation performance. Attached Figure Description

[0023] Example:
[0024] like Figures 1-4 As shown, the thermal insulation solid wood composite flooring includes, from bottom to top, a balance layer 1, a first insulation layer 2, an adhesive reinforcement layer 3, a solid wood layer 4, a second insulation layer 51, and a wear-resistant layer 52. The first insulation layer 2 includes heat insulation boards 21 and 22 that are alternately distributed horizontally and vertically. A reflective film 23 is provided at the joint between the heat insulation boards 21 and 22. One side of the solid wood layer 4 is provided with a splicing groove 41, and the other side of the solid wood layer 4 is provided with a splicing protrusion 42 that matches the splicing groove 41. The inner bottom surface and inner side surface of the splicing groove 41 are provided with a first elastic strip 43, and the inner top surface of the splicing groove 41 is provided with a locking block 44. The splicing protrusion 42 is provided with a locking groove 45 that corresponds to the locking block 44, and the locking groove 45 is provided with a second elastic strip 46.
[0025] This invention uses a first insulation layer 2 to prevent cold air from entering the floor and a second insulation layer 51 to reduce heat loss upwards, forming "two-way insulation" and improving the floor's insulation effect. The first insulation layer 2 combines an insulation board 21, an insulation board 22, and a reflective film 23. The insulation board 21 and the insulation board 22 are used to block heat transfer, effectively preventing indoor heat loss to the floor and the low temperature of the floor from being conducted to the floor. The reflective film 23 conducts heat upwards, thereby reducing heat loss and better retaining heat. Furthermore, the insulation board 21 and the insulation board 22 are arranged alternately in the horizontal and vertical directions, which can improve the floor's resistance to deformation. The reflective film 23 is located at the joint between the insulation board 21 and the insulation board 22, improving the tightness of the first insulation layer 2 and preventing heat from escaping from the gaps, thereby further improving the insulation effect.
[0026] Adjacent floorboards are joined together using splicing grooves 41 and splicing protrusions 42. Locking blocks 44 and slots 45 are also provided on the splicing grooves 41 and 42 to improve splicing stability. First elastic strips 43 and second elastic strips 46 with a certain deformation capacity are provided on the splicing grooves 41 and 45, ensuring that the splicing protrusions 42 and 44 fit tightly with the first elastic strips 43 and second elastic strips 46 during splicing. This results in a tighter splice, preventing damage from compression between floorboards even in the event of thermal expansion and contraction, reducing gaps and heat loss at the splicing seams, improving the connection stability and sealing of the floorboards, and thus enhancing their thermal insulation performance.
[0027] The outer surfaces of both the first elastic strip 43 and the second elastic strip 46 are arc-shaped, and both the first elastic strip 43 and the second elastic strip 46 have cavities 47 inside. The first elastic strip 43 and the second elastic strip 46 can be made of elastic insulation felt. The arc-shaped surface and the cavity 47 design improve the elastic deformation capability of the first elastic strip 43 and the second elastic strip 46.
[0028] The insulation board 22 is made of polystyrene board or rock wool board; the heat insulation board 21 is made of vacuum heat insulation board or polystyrene heat insulation board; and the reflective film 23 is made of aluminum foil reflective film. These materials effectively improve the heat insulation performance while also providing certain sound insulation and moisture protection.
[0029] The bonding reinforcement layer 3 includes a fiberglass mesh 31, with polymer mortar layers 32 on both the upper and lower layers of the fiberglass mesh 31. The fiberglass mesh 31, in conjunction with the polymer mortar layers 32, provides toughening and reinforcement, and is less prone to delamination, thus improving the performance of the flooring and extending its service life.
[0030] The bottom of the balancing layer 1 is provided with a moisture-proof layer 6, and the interior of the moisture-proof layer 6 is filled with adsorption layers 61 at intervals. The bottom of the moisture-proof layer 6 is provided with micropores 62 that communicate with the adsorption layers 61. The moisture-proof layer 6 prevents moisture from the ground from eroding into the floor structure. The adsorption layers 61 can absorb moisture and humidity, reducing the possibility of moisture eroding into other floor structure layers, thus improving moisture-proof performance.
[0031] The wear-resistant layer 52 is made of aluminum oxide or UV coating to improve the surface wear resistance of the floor.
[0032] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
