Technical Field

The utility model belongs to the wood laminate flooring field that low floor was used especially relates to a core three layer construction's that low floor was used wood laminate flooring.

Background

The core board of the solid wood composite floor (floor for short) is usually composed of a plurality of layers of solid wood boards, the fiber directions of the solid wood boards between the upper layer and the lower layer are mutually vertical, so that the deformation stress directions between the solid wood boards on the upper layer and the solid wood boards on the lower layer are different, the deformation stress generated by a single-layer solid wood board is limited by the adjacent layer of solid wood boards under the action of glue, and therefore, each layer of solid wood board is ensured to be straight, the floor has good structural stability, and the whole floor is not easy to. However, after the environmental humidity reaches a certain degree, especially in the environment of low floors (one floor and two floors) in plum rain season, the solid wood boards are affected by moisture in the air, the volume of the solid wood boards is increased after being affected by moisture, the generated deformation stress is correspondingly increased, the deformation stress can overcome the bonding force of glue and is separated from the limitation of the solid wood boards of adjacent floors, so that the solid wood boards are bent, and the solid wood boards are separated from each other due to the fact that the directions of the deformation stress between the solid wood boards of the upper floor and the solid wood boards of the lower floor are different, so that the solid wood boards of the upper floor and the solid wood boards.

Therefore, the existing solid wood composite floor has the defect that interlayer peeling is easy to occur in a humid environment.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. As shown in fig. 1, the solid wood composite floor with a three-layer core structure comprises a core board, wherein a decorative layer 1 is arranged on the top surface of the core board, a balance layer 2 is arranged on the bottom surface of the core board, and the core board is formed by compounding a top board 3, a middle board 4 and a bottom board 5 through glue; the grain direction of the top plate 3 is consistent with the length direction of the top plate 3, and a plurality of first through grooves 6 vertical to the length direction of the top plate 3 are arranged on the bottom surface of the top plate 3; the grain trend of the middle plate 4 is vertical to the length direction of the middle plate 4, and a plurality of second through grooves 7 parallel to the length direction of the middle plate 4 are arranged on the top surface and the bottom surface of the middle plate 4; the grain direction of the bottom plate 5 is consistent with the length direction of the bottom plate 5, and a plurality of third through grooves 8 vertical to the length direction of the bottom plate 5 are arranged on the top surface of the bottom plate 5; and rivets 9 for connecting the top plate 3, the middle plate 4 and the bottom plate 5.

The decorative layer 1 is the log veneer of 1mm thick, balanced layer 2 is thickness 1 mm's beech board, roof 3 and bottom plate 5 are 4mm thick eucalyptus wooden boards, medium plate 4 is the russian siberian cinnamomum pini plank of 8mm thick, and the texture of russian siberian cinnamomum pini is light soft, the material is tough and tensile, can make the stability on floor better, the feel comfort level is better, has fine protection against insects decay nature moreover.

The rivet 9 is only one and is located in the middle of the core plate, or the rivets 9 are multiple and are evenly distributed along the central axis of the core plate.

The width and the depth of the first through groove 6, the second through groove 7 and the third through groove 8 are all 0.8mm and 1.5mm respectively.

The distance between the adjacent first through grooves 6 is 75mm, the distance between the adjacent second through grooves 7 is 23m, and the distance between the adjacent third through grooves 8 is 75 mm.

The second through grooves 7 on the top surface of the middle plate 4 and the second through grooves 7 on the bottom surface of the middle plate 4 are arranged in a staggered manner, so that the strength of the middle plate 4 is prevented from being reduced too much.

The first through groove 6, the second through groove 7 and the third through groove 8 are all provided with silica gel strips, and the silica gel strips are formed by filling liquid silica gel and fixing the silica gel strips in corresponding grooves.

The side wall of the floor is provided with a mortise structure, which is the prior art and is not shown in the attached drawings.

The lateral wall of the core plate is coated with tung oil, so that the infiltration of moisture from the lateral wall of the core plate can be reduced.

The working principle is as follows: as shown in fig. 4, since the grain of the middle plate 4 runs perpendicular to the longitudinal direction of the middle plate 4, the bending axis of the middle plate 4 is parallel to the longitudinal direction of the middle plate 4, the middle plate 4 is bent in the width direction, and the bending of the middle plate 4 is mainly caused by the stress difference generated by the unequal stress between the top surface and the bottom surface of the middle plate 4, which generates the bending torque with respect to the middle surface of the middle plate 4, thereby causing the middle of the middle plate 4 to bend upward or downward. Through set up second through groove 7 on the top surface and the bottom surface of medium plate 4, the transmission of destruction stress on medium plate 4 top surface and bottom surface makes stress mainly concentrate on the layer at second through groove 7 bottom surface place, reduces the distance between stress difference and the medium side of medium plate 4, can reduce the stress difference and produce the bending torque value for the medium side of medium plate 4, and this bending torque is overcome the elimination by the cohesion of glue easily, so medium plate 4 is difficult to take place the bending.

As shown in fig. 5, since the grain direction of the top plate 3 coincides with the longitudinal direction of the top plate 3, the bending axis of the top plate 3 is perpendicular to the longitudinal direction of the top plate 3, and the top plate 3 is bent in the longitudinal direction. Under the action of moisture, the whole expansion of the top plate 3 generates stress, the bottom surface of the top plate 3 is grooved, the stress on the bottom surface of the top plate 3 is partially eliminated, the stress on the bottom surface of the top plate 3 is smaller than the stress on the top surface, the bending trend of the top plate 3 is caused to be that the middle part is arched upwards, namely, the top plate 3 has the bending stress with the middle part bulging upwards, most of the bending stress is overcome under the action of the rivets 9, and the rest part can be overcome by the bonding force of glue easily, so that the top plate 3 is not easy to bend. The same applies to the bottom plate 5.

The utility model discloses be difficult to take place the advantage that the layer peeled off under humid environment, have in addition to trample the less advantage of noise.
