Embodiment 1

[0022] Example 1: Floor

[0023] The floor shown in Fig. 1, 2, from top to bottom is table board 1, base material 2 successively, and forms with adhesive pressing between adjacent two boards. The surface board 1 is a sawn solid wood veneer or bamboo veneer, and the thickness A is 4mm. The surface M of the substrate 2 (that is, the joint surface with the surface plate 1) is a wood cross-section, and the thickness B is 6 mm. The fiber direction F1 of the surface board 1 is a horizontal direction, and the wood fiber direction F2 of the substrate 2 is a vertical direction, and they are perpendicular to each other.

[0024] Both sides of the base material 2 are provided with a tenon 8 and a tenon groove 9 .

Embodiment 2

[0025] Example 2: Making the base material with laminated veneer lumber

[0026] As shown in Fig. 3, the laminated veneer lumber P formed by coating and pressing the laminated veneer 10 parallel to the fiber direction of the multi-layer, its surface is the wood chord section, and the fiber direction is F2. Use the circular saw blade 7 to cut the laminated veneer lumber P into strips 4 in the transverse direction perpendicular to the fiber direction F2, turn the strips clockwise 90 degrees (as shown in Figure 4), apply glue on the side, and then press T Under the action of lateral pressure (as shown in Figure 5), the base material 2 (as shown in Figure 6) is obtained. The fiber direction F2 of the substrate 2 is a vertical direction, and the surface M is a transverse plane. It can be seen from the figure that the sawn width of the slats is the thickness B of the base material.

[0027] The surface board is bonded to the surface M of the obtained substrate 2, and the fiber dir...

Embodiment 3

[0028] Example 3: Making the base material with laminated veneer lumber

[0029] As shown in Figure 7, the laminated veneer lumber P formed by coating and pressing the laminated veneer 10 parallel to the fiber direction of the multi-layer, its surface is the wood chord section, and the fiber direction is F2. Use the circular saw blade 7 to cut the laminated veneer lumber P into strips 5 in the longitudinal direction parallel to the fiber direction F2, turn the strips clockwise 90 degrees (as shown in Figure 8), apply glue on the side, and then press T Under the action of side pressure (as shown in Figure 9), the base material 2 (as shown in Figure 10) is obtained. The fiber direction F2 of the substrate 2 is a horizontal direction, and the surface M is a radial section. It can be seen from the figure that the sawn width of the slats is the thickness B of the base material.

[0030] The surface plate is bonded to the surface M of the obtained base material 2, and the fiber di...

Abstract

The invention provides a warpproof floor and manufacturing process thereof. This floor comprises a face board and a base material, the surface of base material is timber cross section, radial section or staggered section of timber cross section and radial section. The method of this floor comprises the steps of cementing the face board and the base material together; the base material is prepared according to the following methods: after sawing the single board laminated wood transversely or longitudinally to lath, the side of the lath is applied glue, a plurality of lath are made by lateral pressures again, or after sawing plywood to lath, the side of the lath is applied glue, a plurality of lath are made by lateral pressures again. This floor has good dimensional stability, and can prevent radically warp deform in use and eliminate crazing phenomenon in use.

Description

technical field [0001] The invention relates to a wooden floor, especially a two-layer structure, which has good dimensional stability during use and prevents warping and deformation and surface cracking; in addition, the invention also relates to a preparation method of the floor and its use as Geothermal floors. Background technique [0002] There are many kinds of wood flooring, such as common solid wood flooring, laminate flooring, solid wood composite flooring and bamboo wood composite flooring on the market, which are selected as interior floor decoration materials because of their beautiful appearance. Wooden floors generally have two or more layers structurally. No matter it is two-layer or multi-layer, the first layer is the surface plate, and the second layer is the substrate. Most of the surface boards are solid wood veneers or bamboo veneers, and the base materials are mostly laminated veneer lumber, plywood, and solid wood veneers. T...
