Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor design, in particular to a three-layer solid wood floor. Background Art
[0002] Solid wood flooring is categorized as either single-layer solid wood or composite solid wood flooring. Single-layer solid wood flooring is made from a single wood species. While the production process is simple, the raw material costs are high, resulting in a higher price. Composite solid wood flooring is made by gluing together multiple layers of solid wood. Only the surface layer is made of high-quality, high-value wood, while the remaining layers use lower-cost, fast-growing wood as the base. This reduces material costs, but the production process is relatively complex. Furthermore, the three layers are made of different materials. Over time, due to the varying properties of the wood, the wood expands and contracts differently, leading to stress deformation and, ultimately, warping and buckling.
[0003] Currently, most of the three-layer solid wood composite floors on the market are processed using conventional methods, resulting in a large number of scraps, which are generally digested by direct combustion or combustion after particle processing, resulting in a huge waste of resources and thus increasing costs.
[0004] Oak has straight texture, sometimes with diagonal grain, coarse structure, beautiful patterns, high mechanical strength, wear resistance, not easy to dry, easy to slice to obtain a smooth surface, and good paint and coloring properties. It is widely used as raw material for furniture and flooring. Summary of the Invention
[0005] The utility model provides a three-layer solid wood floor to solve the shortcomings of existing composite solid wood floors, such as easy deformation due to different materials, waste of resources and high cost.
[0006] A three-layer solid wood floor, consisting of a surface board, a core board and a back board, all of which are made of the same material solid wood, with the surface board and the back board distributed and bonded to the two surfaces of the core board.
[0007] The panel comprises four frames, a left-leaning panel and a right-leaning panel, the four frames forming a square panel, the left-leaning panel and the right-leaning panel being cross-jointed on the four frames at an angle of 90 degrees;
[0008] The core board is composed of several solid wood strips fixed and spliced in parallel;
[0009] The backboard is composed of an array of transverse boards and longitudinal boards, which are stacked and spliced from the center to the surrounding areas. Two first transverse boards are aligned and spliced, two first longitudinal boards are spliced on both sides of the two first transverse boards, two second transverse boards are spliced outside the two first transverse boards and the two first longitudinal boards, and two second longitudinal boards are spliced on both sides of the two first longitudinal boards and the two second transverse boards. In this way, the array of transverse boards and longitudinal boards are spliced outward to form the backboard.
[0010] The adjacent solid wood strips constituting the core board are fixed by gluing.
[0011] One side of the several solid wood strips constituting the core board is provided with several grooves in the transverse direction, strips are fixedly laid in the grooves, and the side with the grooves is bonded to the surface board.
[0012] The strip is a paper rope.
[0013] The strip is fixed in the groove by bonding.
[0014] The strip is pressed into the groove by pressure.
[0015] The surface plate, core plate and back plate are all made of oak.
[0016] Beneficial effects of the utility model:
[0017] This utility model adopts the traditional three-layer wood grain direction crisscross processing to save wood resources. In the current environment of reducing carbon emissions, it can effectively utilize the waste generated by wood processing residues, reduce costs, reduce the amount of glue applied, reduce formaldehyde release, ensure environmental protection, and solve the stress problem caused by the three layers being made of the same material, ensuring the stability of the floor.
