Abstract

A decorative sheet material, comprising a long or square sheet body having a first side and a second side opposite to each other, wherein: the first side surface is convexly provided with at least two connecting tenons arranged at intervals from top to bottom, and the second side surface is concavely provided with at least two connecting grooves arranged at intervals matched with the connecting tenons of the first side surface from top to bottom. The connecting tenon and the connecting groove of the utility model have at least two channels, compared with a single-groove tenon matching structure, the matching area of the groove and tenon joint of the plate body is enlarged, the friction force is increased, and the engaging platform of the groove and tenon joint of the plate body is more compact, the stability is good, and the connecting strength is high; in addition, because the connecting grooves and the connecting tenons are of a multi-layer structure, when the board body is cleaned by water, the water is blocked by the uppermost connecting groove or connecting tenon and cannot permeate into the rest connecting grooves or connecting tenons below, and the phenomenon that the board body is deformed or arched due to water permeation can be reduced. The design of the long mortise and the short mortise can save wood resources more than that of a common single tenon, and brings better economic value.

Description

a decorative plate

Technical field:

The utility model relates to a decorative plate.

Background technique:

Existing decorative boards, such as wooden floors, generally have a structure in which a single connection groove and a single connection tenon are matched and connected, and the cross-section of the tenon and groove is a semicircular structure, as shown in FIG. The wooden floor of this structure has the following defects: 1. The groove and tenon fit area is limited, the stability is poor, and the connection strength is low; 2. The groove and tenon bite is not firm, and there is noise in the floor during use; The groove and tenon joint of the floor penetrates from the upper surface of the floor, causing the floor to arch and deform due to moisture.

Invention content:

The purpose of the utility model is to provide a decorative plate with good stability and high connection strength.

A decorative plate, including a long or square plate body, the plate body has a first side and a second side opposite to each other. The connecting tenon, the second side is concavely provided with at least two connecting grooves arranged at intervals matched with the connecting tenon on the first side from top to bottom.

The utility model has at least two connecting tenons and connecting grooves. Compared with the single-groove tenon matching structure, the matching area of the board groove and the tenon joint is enlarged, and the friction force is increased, so that the board groove and the tenon joint are occluded. More compact, good stability, and high connection strength; in addition, because the connection groove and the connection tenon are multi-layered, when the board is cleaned with water, the water will be blocked by the top connection groove or connection tenon, and cannot penetrate into the rest of the connections below Grooves or connecting tenons can reduce the deformation or arching of the board due to the infiltration of water.

There are two connecting tenons, including a first connecting tenon and a second connecting tenon. The first connecting tenon starts from the top surface of the board body; there are two connecting grooves, including a second connecting tenon matched with the first connecting tenon. A connecting groove and a second connecting groove matched with the second connecting tenons, the first connecting groove starts from the top surface of the board body, which makes the utility model simple in structure and convenient in installation and splicing of the board body.

The protrusion height of the first connecting tenon is lower than that of the second connecting tenon, the structure is simple, the installation and splicing of the boards are convenient, and the separation of the wood during the process of swelling and shrinking can be reduced; and the first and second connections of the utility model The mortise is designed with different lengths and lengths, which saves wood material compared with ordinary single mortise and groove, which is conducive to saving resources and creating value. The wood area lost by the new type of long and short tenon and groove is only the width of the short tenon, which is the width of the first connecting tenon multiplied by the length of the first connecting groove. The width of the short tenon is 2mm, while the ordinary single tenon and tenon will The wood area lost by the groove is the width of the single connecting tenon 4mm multiplied by the length of the single connecting groove, so that the newly designed long and short tenon can save a certain amount of waste of wood area, because the floor has a large amount of processing, the economic value of this saving very big.

The thickness of the first connecting tenon is thinner than that of the second connecting tenon, the structure is simple, the installation and splicing of the plates are convenient, and the joint separation during the process of swelling and shrinking of wood is reduced.

The upper surface of the board body is respectively provided with symmetrical inclined chamfers at the edges of the first connecting tenon and the first connecting groove. After the boards are spliced and installed, V-shaped grooves are formed at the joints of the upper surfaces, and the upper surface of the boards is more beautiful.

When the first side is mated with the second side, expansion joints are left at least below the mating surfaces of the first connecting tenon and the first connecting groove. When the boards are spliced together, an anti-deformation expansion joint is provided between the end surface of the second connecting tenon and the bottom surface of the second connecting groove, which is scientifically designed and can inhibit the arching or deformation caused by the expansion of the board when it is wet.

As a further improvement of the above-mentioned solution, the said expansion joint increases gradually from top to bottom. Since the bottom of the decorative panels such as the floor and the ground is most susceptible to moisture and has the largest expansion and contraction, the expansion joints gradually increase from top to bottom to reasonably solve this problem.

The cross-sections of the first connecting tenon, the second connecting tenon, the first connecting groove and the second connecting groove are rectangular, and the grooves and tenons are firmly engaged, which can reduce the noise generated during the use of the board.

Detailed ways:

A decorative board, especially a double-groove wooden floor, comprising a board body 1, the first side of the board body 1 protruding from top to bottom with first connecting tenons 2 and second connecting tenon 3 arranged at intervals, the board The second side of the body 1 is concavely provided with first connecting grooves 4 matched with the first connecting tenons 2 arranged at intervals and second connecting grooves 5 matched and installed with the second connecting tenons 3 . The cross sections of the two connecting tenons and the first and second connecting grooves are rectangular. The protrusion height of the first connecting tenon 2 is lower than that of the second connecting tenon 3, and the recessed depth of the first connecting groove 4 is shallower than that of the second connecting groove 5; the thickness of the first connecting tenon 2 is lower than that of the second connecting tenon. The tenon 3 is thin, and the width of the first connecting groove 4 is smaller than that of the second connecting groove 5; a lower groove 8 is provided between the second connecting tenon 3 and the bottom surface of the plate body 1, and the second connecting groove 5 and the plate body 1. There is a lower tenon 9 between the bottom surfaces. When the boards 1 are spliced together, the lower tenon 9 and the lower groove 8 are matched and installed, and an expansion joint 61 is provided between the mating surfaces of the lower tenon 9 and the lower groove 8. At the same time, the second connection An expansion joint 62 is also provided between the mating surfaces of the tenon 3 and the second connecting groove 5 , and the size of the expansion joint 61 is larger than that of the expansion joint 62 .
