Description

Technical Field

[0001] The utility model relates to the technical field of solid wood boards, in particular to a cross-mortise solid wood board. Background Art

[0002] As a common decoration material, solid wood boards are usually made of wood. However, under climate change, solid wood boards will repeatedly experience moisture and drying processes, which will cause lateral expansion and contraction deformation and distortion caused by deformation of the wood along the wood grain curve, seriously affecting the flatness of the solid wood boards. The solid wood boards currently on the market have obvious deficiencies in dealing with this deformation problem. For example, traditional solid wood board structures are often unable to effectively control deformation when faced with the impact of climate change, which brings a lot of inconvenience to users. In order to improve this situation, Chinese utility model patent CN2404656Y once disclosed a wooden floor with a cross bottom groove, which attempts to cut off the wood fibers at the bottom of the wooden floor by opening longitudinal through grooves and transverse through grooves at the bottom, hoping to achieve the purpose of reducing distortion, but some problems are exposed in actual applications. On the one hand, prevention of twisting and deformation mainly relies on transverse through grooves. It can be seen from the description and drawings of the patent that the transverse through grooves cannot be set too deep, otherwise the wooden floor will easily break. However, if the transverse through grooves are too shallow, the effect of preventing twisting and deformation will be poor. On the other hand, the wooden floor is a single-layer structure, and its deep transverse grooves, the mating surfaces of the falcon strips and the transverse through grooves are extremely susceptible to accelerated thermal expansion and contraction deformation of the wooden floor due to water seepage. Utility Model Content

[0003] In view of this, the utility model proposes a cross-mortise solid wood board to improve the anti-twisting and deformation performance and strength of the solid wood board.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A cross-mortise solid wood board comprises a base plate, a first panel and a second panel; the front surface of the base plate is provided with deep grooves at intervals along its length direction, and falcon strips are embedded in the deep grooves, and the top surface of the falcon strips is flush with the top surface of the base plate; the first panel is pressed onto the top surface of the base plate and the falcon strips, and the second panel is pressed onto the bottom surface of the base plate.

[0006] To better implement the above technical solution, optionally, the back side of the substrate is provided with first shallow grooves at intervals along its width direction, and the first shallow grooves intersect with the deep groove spaces and are connected or disconnected at the intersection of the spaces.

[0007] Optionally, the front side of the substrate is provided with second shallow grooves spaced apart between the deep grooves along its width direction, and the second shallow grooves are parallel to the first shallow grooves and are staggered along the thickness direction of the substrate.

[0008] Optionally, both ends of the deep groove are closed ends.

[0009] Optionally, the distance between both ends of the deep groove and the corresponding side edges of the substrate is 0.1 - 5 cm.

[0010] Optionally, both ends of the first shallow groove are open ends.

[0011] Optionally, the depth of the deep groove is 3.5 - 60 times the depth of the first shallow groove and the second shallow groove respectively.

[0012] Optionally, the material of the substrate includes merbau, discus bean, oak, ramin, ash, teak, black walnut, and kompas.

[0013] Optionally, the materials of the first panel and the second panel include black walnut, rosewood, oak, ash, teak, rosewood, merbau, ramin, discus bean, and the material of the substrate is different from that of the first panel and the second panel.

[0014] Advantages of the present utility model:

[0015] For a cross-mortise solid wood board of the present utility model, the wood fibers at the top of the substrate are cut off by the deep groove, thereby reducing the deformation of the substrate along the wood fiber line. By inserting tenon strips into the deep groove, on the one hand, the strength of the substrate can be improved, and on the other hand, the upward warping of both sides caused by the drying shrinkage at the top of the substrate and the downward warping of both sides caused by the swelling due to moisture absorption at the top can be reduced. By pressing the first panel on the top surface of the substrate and the second panel on the bottom surface of the substrate, a multi-layer solid wood board can be formed. On the one hand, it helps to increase the strength of the solid wood board, and on the other hand, both the top and bottom surfaces of the solid wood board can be used as decorative surfaces, which helps to expand the usage scenarios.

[0016] For a cross-mortise solid wood board of the present utility model, the first shallow groove provided on the bottom surface of the substrate can cut off the wood fibers at the top of the substrate, and the wood fibers at the bottom of the substrate are cut off by the first shallow groove. Furthermore, the wood fibers of the substrate are separated into several small pieces by the deep groove, the first shallow groove, and the intersection of the deep groove and the first shallow groove. Thereby, the deformation of the substrate along the wood fiber line can be reduced. The first shallow groove can provide space for the thermal expansion of the bottom of the substrate, thus preventing the upward warping of both sides caused by the swelling of the bottom of the substrate due to moisture absorption.

[0017] For a cross-mortise solid wood board of the present utility model, the second shallow groove provided on the top surface of the substrate can cut off the wood fibers between the deep grooves, further reducing the amount of deformation of the substrate along the wood fiber line, and at the same time reducing the influence of thermal expansion and contraction on the top plate of the substrate.

[0026] The technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The same components are denoted by the same reference numerals.

[0027] Embodiment 1

[0028] Please refer to Figure 1 and Figure 2 , Embodiment 1 discloses a cross-mortise solid wood board, including a substrate 10, a first panel 20 and a second panel 30.

[0029] As Figure 2 shown, deep grooves 11 are arranged at intervals along the length direction of the front surface of the substrate 10, tenon strips 13 are embedded in the deep grooves 11, the top surface of the tenon strips 13 is flush with the top surface of the substrate 10, the first panel 20 is pressed on the top surfaces of the substrate 10 and the tenon strips 13, and the second panel 30 is pressed on the bottom surface of the substrate 10.

[0030] A cross-mortise solid wood board according to an embodiment of the present utility model has deep grooves 11 spaced apart on the top surface of the substrate 10, which can cut off the wood fibers at the top of the substrate 10, thereby reducing the deformation of the substrate 10 along the wood fiber line. A tenon strip 13 is embedded in the deep groove 11. On the one hand, it can enhance the strength of the top of the substrate 10 at the deep groove 11, and on the other hand, it can also reduce the upward warping of the two sides caused by the dry shrinkage of the top of the substrate 10 and the downward arching of the two sides caused by the swelling of the top due to moisture. A first panel 20 is pressed on the top surface of the substrate 10, and a second panel 30 is pressed on the bottom surface of the substrate 10 to form a multi-layer solid wood board. On the one hand, it helps to increase the strength of the solid wood board, and on the other hand, both the top and bottom surfaces of the solid wood board can be used as decorative surfaces, which helps to expand the usage scenarios.

[0031] In the embodiment of the present utility model, both ends of the deep groove 11 are closed ends, and the distance between both ends of the deep groove 11 and the corresponding side edges of the substrate 10 is 0.1 - 5 cm. When both ends of the deep groove 11 are closed ends, the top of the substrate 10 can be connected to form an integral structure.

[0032] In the embodiment of the present utility model, the material of the substrate 10 includes merbau, iroko, oak, ramin, ash, teak, black walnut, and compass. The materials of the first panel 20 and the second panel 30 include black walnut, rosewood, oak, ash, teak, rosewood, merbau, ramin, and iroko. The materials of the substrate 10 are different from those of the first panel 20 and the second panel 30. The thickness of the first panel 20 and the second panel 30 is 0.4 - 4.0 mm. The thickness of the first panel 20 and the second panel 30 can be selected according to the usage scenario of the solid wood board and the thickness of the substrate 10. When the solid wood board is used as a floor, the thickness of the first panel 20 and the second panel 30 can be selected as 2.0 - 4.0 mm. When the solid wood board is used as a board of a cabinet, its thickness can be selected as 0.4 - 4.0 mm.

[0033] Embodiment 2

[0034] Please refer to Figures 3 to 5 , this embodiment is similar to Embodiment 1, and the difference lies in that: first shallow grooves 12 are provided at intervals along the width direction on the back surface of the substrate 10, and the first shallow grooves 12 intersect with the deep grooves 11 in space and are connected or separated at the space intersection.

[0035] A cross-mortise solid wood board according to an embodiment of the present utility model has a first shallow groove 12 provided on the bottom surface of the substrate 10. The deep groove 11 and the first shallow groove 12 intersect with each other in space and are connected or separated at the intersection. This can cut the wood fibers at the top of the substrate 10 by the deep groove 11 and cut the wood fibers at the bottom of the substrate 10 by the first shallow groove 12. Furthermore, the wood fibers of the substrate 10 are separated into several small pieces by the deep groove 11, the first shallow groove 12, and the intersection of the deep groove 11 and the first shallow groove 12. Thus, the deformation of the substrate 10 along the wood fiber line can be reduced. The first shallow groove 12 can provide space for the thermal expansion of the bottom of the substrate 10, which can prevent the two sides of the substrate 10 from warping upwards due to moisture expansion at the bottom.

[0036] In an embodiment of the present utility model, both ends of the first shallow groove 12 are open ends, which can form a strip structure parallel to each other at the bottom of the substrate 10 to facilitate adapting to the thermal expansion and contraction of the substrate 10.

[0037] In an embodiment of the present utility model, the depth of the deep groove 11 is 3.5 - 60 times the depth of the first shallow groove 12. Preferably, the depth of the deep groove 11 is 4 times the depth of the first shallow groove 12. When the thickness of the substrate 10 is 18 mm, the depth of the deep groove 11 is 14.4 mm, and the depth of the first shallow groove 12 is 3.6 mm. The vertical distance between adjacent deep grooves 11 is 5 - 20 cm, and the distance between adjacent shallow grooves 12 is 1 - 20 cm. Through experimental measurement, the substrate 10 with this specification has better anti-deformation ability when detected under the condition of temperature -10° - 38°.

[0038] Embodiment 3

[0039] Please refer to Figure 6 , this embodiment is similar to Embodiment 1, and the difference lies in that: on the front surface of the substrate 10, second shallow grooves 14 located between the deep grooves 11 are provided at intervals along the width direction. The second shallow grooves 14 and the first shallow grooves 12 are parallel to each other and are arranged in a staggered manner along the thickness direction of the substrate 10. Specifically, the width and depth of the second shallow grooves 14 are the same as those of the first shallow grooves 12, and the length of the second shallow grooves 14 is shorter than the length of the first shallow grooves 12. Preferably, both ends of the second shallow grooves 14 are respectively connected to two adjacent deep grooves 11. By providing the second shallow grooves 14 on the top surface of the substrate 10, the wood fibers between the deep grooves 11 can be cut by the second shallow grooves 14, which can further reduce the amount of deformation of the substrate 10 along the wood fiber line and at the same time reduce the influence of thermal expansion and contraction on the top plate of the substrate 10.

The described specific embodiments are used to help understand the idea of the present utility model. The derivations and deformations made by those skilled in the art based on the specific embodiments of the present utility model also fall within the protection scope of the present utility model.
