SOLID WOOD COMPOSITE FLOOR BASE MATERIAL HAVING FISHBONE-SHAPED CORE MATERIAL

Abstract

A solid wood composite floor base material includes a central transverse grain core plate, insertion strips on two sides of the central transverse grain core plate, a surface layer, a bottom layer panel, and a longitudinal grain batten. The longitudinal grain batten is embedded in the middle of the central transverse grain core plate in the length direction. The central transverse grain core plate is divided into a left part and a right part by the middle longitudinal grain batten, i.e., a left central transverse grain core plate and a right central transverse grain core plate. The middle longitudinal grain batten, the left central transverse grain core plate and the right central transverse grain core plate form a fishbone-shaped wood grain structure.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] FIG. 1 is a schematic diagram of a solid wood composite floor base material of the disclosure; and

[0014] FIG. 2 is a schematic diagram showing the bond between the central transverse grain core plate, the middle longitudinal grain batten and the insertion strips on the two sides.

DETAILED DESCRIPTIONS

[0015] FIG. 1 and FIG. 2 are examples of a solid wood composite floor base material of the disclosure.

[0016] A solid wood composite floor base material having a fishbone-shaped core material of the disclosure comprises a central transverse grain core plate 1, insertion strips 2, 3 on the two sides, a surface layer 4, and a bottom layer panel 5. A longitudinal grain batten 6 is embedded in the middle of the central transverse grain core plate 1 in the length direction. The central transverse grain core plate 1 is divided into a left part and a right part by the middle longitudinal grain batten 6, i.e., a left central transverse grain core plate 1a and a right central transverse grain core plate 1b. The middle longitudinal grain batten 6, the left central transverse grain core plate 1a and the right central transverse grain core plate 1b form a fishbone-shaped wood grain structure.

[0017] The widths of the left central transverse grain core plate 1a and the right central transverse grain core plate 1b are equal.

[0018] The insertion strips 2, 3 on the two sides are bonded with the left central transverse grain core plate 1a, the right central transverse grain core plate 1b, and the middle longitudinal grain batten 6.

[0019] The panels of the surface layer 4 and/or the bottom layer panel 5 are made of wood veneers which are 2-5 mm thick and have rotary-cut transverse wood grains, and the wood veneers are coated and laminated above and below the left central transverse grain core plate 1a, the right central transverse grain core plate 1b, the middle longitudinal grain batten 6, and the insertion strips 2, 3 on the two sides by means of an adhesive.

[0020] The central transverse grain core plate of the base material plates of the disclosure is made of fast-growing species or coniferous species.

[0021] The central transverse grain core plate and the insertion strips (hard batten) on the two sides are connected as a whole by bonding means, such as by adhesive cold pressing (or hot pressing). The surface layer and the bottom layer panel are made of wood veneers which are 2-5 mm thick and have rotary-cut transverse wood grains, and the wood veneers are coated thereon and then bonded by means of an adhesive and finally made into the floor by mechanical processing. The disclosure is also suitable for making floors of various shapes, such as ordinary straight floors or curved floors.

[0022] The core of the disclosure is that the longitudinal grain batten is embedded in the middle of the central transverse grain core plate in the length direction, enabling to make the left central transverse grain core plate, the right central transverse grain core plate and the middle longitudinal grain batten form a fishbone-shaped wood grain structure. The disclosure makes full use of fast-growing wood and narrow wood and improves the flexural strength of the plate body. Therefore, any base material or floor with a middle longitudinal grain batten in the length direction belongs to the protection scope of the present disclosure.
