Description

TECHNICAL FIELD

[0001] The utility model relates to a mortise and tenon structure two-layer solid wood floor, in particular to a wood floor adopting shrinkage gap to solve the deformation problem caused by wood floor dry shrinkage and wet expansion. BACKGROUND

[0002] At present, the wood floor on the market mainly has solid wood floor, reinforced floor and solid wood composite floor etc. The solid wood floor has natural texture and comfortable foot feeling, is formed by natural wood after drying and processing, and has the characteristics of winter warm, summer cool, good touch, nature, softness and affinity, so it becomes the ideal material for ground decoration of bedroom, living room, study room and the like, however, the whole pure solid wood floor is manufactured by natural precious wood, the cost is high, resources are wasted, and the solid wood floor is prone to dry shrinkage off-joint, wet arching and other problems, although some two-layer solid wood floors of combination and splicing appear on the market, but the floor cannot well solve the deformation problem caused by dry shrinkage and wet expansion, and the stability of the two-layer solid wood floor is not high. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at providing a mortise and tenon structure two-layer solid wood floor which can well solve the deformation problem caused by wood floor dry shrinkage and wet expansion and has good structural stability, so as to solve the problems of complex production process and high cost of the existing solid wood composite floor.

[0004] The technical solution of the utility model is that on the basis of the bottom plate, the face plate and the face plate and the bottom plate being installed in up-down superposition, the feature is that there is a balance strip, the left and right sides of the bottom plate are respectively provided with a tongue and a groove in the middle, there is not less than one longitudinal arrayed dovetail groove penetrating the width of the bottom plate and not less than one transverse arrayed shrinkage gap penetrating the length of the bottom plate on the top of the bottom plate, and the balance strip is inserted into the dovetail groove for installation.

[0005] The length of the balance strip is equal to the width of the bottom plate, the cross-sectional shape of the balance strip is the same as that of the dovetail groove, and the interval distance between the dovetail grooves is 20cm-40cm.

[0006] The working principle of the utility model is that the face plate and the bottom plate are installed in up-down superposition, the dovetail groove and the shrinkage gap are arrayed on the top of the bottom plate, the wood floor and the wood floor are spliced by the tongue and the groove, the wood grain of the dovetail groove is perpendicular to the wood grain of the bottom plate and the face plate. The dovetail groove and the balance strip have angles on the side surfaces, so that the bottom plate has high structural stability and is not prone to fracture and off-joint, the transverse warping problem of the wood floor is solved, meanwhile, a plurality of gaps are formed in the longitudinal direction of the bottom plate, the gaps can provide space for the shrinkage or expansion of the solid wood floor in the dry or wet state, the deformation problem of the wood floor caused by dry shrinkage and wet expansion is solved, and the service life of the solid wood floor is improved.

[0007] The advantages of this utility model are that it can be quickly and easily spliced ​​into flooring by gluing the tongue and groove. The expansion gap provides space for the wood flooring to shrink or expand when it is dry or wet, solving the problem of deformation caused by the shrinkage and expansion of wood flooring. The balance bar adopts a trapezoidal structure, which strengthens the stability of the bottom board structure and prevents problems such as lateral warping of the wood flooring.

[0011] Example 1

[0012] according to Figure 1 , Figure 2 , Figure 3 As shown, the directions of front, back, left, right, up, and down in this embodiment are described with reference to... Figure 1 Based on the stacked installation of base plate 2, panel 1, and panel 1 on top of base plate 2, the feature is the presence of a balance bar 3. The base plate 2 has tenons 2.1 and mortises 2.2 located at the center of its left and right sides, respectively. Four dovetail grooves extending through the width of the base plate are arranged longitudinally on the top of the base plate 2, and seventeen expansion joints 2.3 extending through the length of the base plate are arranged transversely. The balance bar 3 is inserted into the dovetail grooves. Panel 1 and base plate 2 have equal length and width, the balance bar 3 has the same length as the width of base plate 2, and the cross-sectional shape of the balance bar 3 is the same as the cross-sectional shape of the dovetail grooves. The spacing between the dovetail grooves is 20cm.

[0013] In this invention, the baseboard 2 is made of fast-growing timber, coniferous wood, and broadleaf wood, while the balance strip 3 is made of broadleaf wood processed from small pieces. The top panel 1 is made of precious broadleaf wood, reducing the amount of precious timber used, significantly lowering costs and minimizing waste of precious timber resources. The wood grain of the baseboard 2 and top panel 1 is perpendicular to the wood grain of the balance strip 3, and a tenon and mortise structure is used to make the connection more secure. The balance strip 3 is vertically inlaid between the baseboard and top panel according to the length and width of the wood flooring, overcoming the internal stress caused by unidirectional isotropic deformation of the wood, increasing the stability of the wood flooring, and greatly reducing the defects of wood flooring deformation due to shrinkage and expansion. The longer or wider the wood flooring, the more balance strips need to be inlaid.

[0014] This utility model's mortise and tenon structure two-layer solid wood flooring features a reasonable structural design, which improves the comprehensive utilization of wood, conforms to the requirements of a low-carbon economy and my country's energy conservation and emission reduction industrial policies, and is a green and environmentally friendly product. Furthermore, this utility model's mortise and tenon structure solid wood flooring retains the inherent advantages of traditional solid wood flooring, such as its decorative appearance, breathability, hardness, texture, and visual appeal. By employing the mortise and tenon structure, it also improves the dimensional stability of the flooring, offering advantages such as convenient production and installation, tight and stable fit between floorboards, and minimal deformation, resistance to twisting and warping. It can be widely used in various environments, especially suitable for underfloor heating.

[0015] The above is a detailed description of the preferred embodiments of this utility model. However, the invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
