Abstract

The utility model discloses a solid wood composite floor, including solid wood layer and base plate layer, the solid wood layer complex is on the base plate layer, and the upper and lower surface on base plate layer all sets up slottedly, sets up the groove on upper surface and sets up the crisscross distribution in the groove of lower surface. The grooves can be distributed transversely along the substrate layer and can be distributed at equal intervals, the width of the grooves can be 0.5 mm-2 mm, the thickness of the substrate layer can be 5-15 mm, and the depth of the grooves can be 1/2-2/3 of the thickness of the substrate layer. The utility model discloses owing to all set up slottedly on the upper and lower surface on base plate layer, set up the groove on upper surface and set up the crisscross distribution in the groove of lower surface, destroyed the base plate in syntropy, reverse ascending tension, overcome the deformation that consequently arouses, the floor is under the condition that keeps rigidity in addition, has increased better pliability, and intensity also increases because of one side and the laminating of wood surface course in the base plate, has overcome the not enough shortcoming of single face grooved bearing strength.

Description

Parquet

technical field

The utility model relates to a solid wood composite floor.

Background technique

The upper solid wood layer of solid wood composite flooring and the base plywood layer are different in moisture content and are affected by external temperature and humidity, resulting in different expansion coefficients, resulting in layered cracks, surface cracks, arching, and warping. Once this kind of solid wood composite floor is twisted, the two ends are upturned, and the middle is arched, etc., the use effect of the floor will be seriously affected, and it may even be completely unusable. In order to change this situation, destroy the tension formed by the opposite stress of the plywood and the solid wood layer of the floor, and the arch warpage formed by the same tensile force, the technicians try to open a transverse groove at the bottom of the floor substrate, that is, the bottom of the plywood along the width direction, so that the floor becomes "soft" ", can be placed and installed obediently along the paved ground. But the disadvantages are: A. This kind of floor is not strong enough, and the load-bearing and compressive strength on the ground keel are more worrying. B. In terms of production technology, Funeng first completes woodworking planing and milling, and then slots. When the "soft" solid wood composite board enters the painting line, when it is painted by rollers, because the rollers are pressed down from the top, it is easy to tilt both ends, and the uneven floor will also cause the hidden danger of the floor being stuck into the machine. After the paint is finished, the grooves will be opened, and the paint film on the floor surface will be damaged, so there are hidden dangers in the remanufacturing of this process.

Utility model content

In view of the above-mentioned shortcomings in the prior art, the purpose of the present utility model is to provide a solid wood composite floor that is not easily deformed and has better flexibility.

The technical solution adopted by the utility model is: a solid wood composite floor, including a solid wood layer and a base plate layer, the solid wood layer is compounded on the base plate layer, grooves are opened on the upper and lower surfaces of the base plate layer, and the grooves arranged on the upper surface are connected with the The grooves on the lower surface are staggered.

The grooves can be distributed laterally along the substrate layer, and can be equidistantly distributed, and the width of the grooves can be 0.5mm-2mm.

The thickness of the substrate layer may be 5-15 mm, and the groove depth may be 1/2-2/3 of the thickness of the substrate layer.

The transverse surface of the groove can be square, circular, triangular or polygonal.

Since the utility model has grooves on the upper and lower surfaces of the substrate layer, the grooves arranged on the upper surface and the grooves arranged on the lower surface are alternately distributed, which destroys the tension of the base plate in the same direction and in the opposite direction, and overcomes the deformation caused by it. Moreover, under the condition of maintaining rigidity, the floor has increased flexibility, and the strength is also increased because one side of the base plate is bonded to the solid wood surface layer, which overcomes the disadvantage of insufficient load-bearing strength of single-sided grooves.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Detailed ways

As shown in Figure 1-2, the solid wood composite flooring of the present utility model includes a solid wood layer 1 and a substrate layer 2. The grooves 3 on the upper surface and the grooves 4 on the lower surface are alternately distributed.

Grooves 3 and 4 can be distributed equidistantly, the width of grooves 3 and 4 can be 0.5mm-2mm, the thickness of substrate layer 2 can be 5-15mm, and the depth of grooves 3 and 4 can be 1/2-1/2 of the thickness of substrate layer 2. 2/3, the transverse surfaces of grooves 3 and 4 can be square, circular, triangular, polygonal or other shapes.

In the production process, the substrate of the solid wood composite board is carried out before the solid wood surface layer is glued, and the upper and lower sides are opened with horizontal grooves, and the positions of the grooves on the two sides are staggered. After the slotting is completed, it enters the solid wood surface layer laminating and gluing process, and then enters the original floor processing procedures such as four-sided planing and double-end milling. The production process is safer and there is no potential safety hazard.
