Abstract

The utility model discloses a solid wood floor with a double-layer structure, which is composed of long wood plates, wherein the wood plates are formed by pressing of decoration layers and weight bearing layers in the thickness direction from top to bottom; tenons which is a tongued-and-grooved structure are respectively arranged on each pair of parallel sides of the wood plates and mutually matched with each other. The utility model is characterized in that the decoration layers adopt solid wood single plates of saw cutting or shaving; the thickness of each solid wood single plate is two to eight MM; the fiber direction of the solid wood single plates is the same as the length direction; the weight bearing layers are composed of wood strips in a transverse array mode at intervals; the distance of the adjacent wood strips is between one to three MM. The utility model is not easy to deform and crack.

Description

The double-decker wooden floor

Technical field

The utility model relates to a kind of floor, is specifically related to the solid wood laminate flooring that a kind of double-decker type gummed forms.

Background technology

The floor of adopting natural wood to process is called wooden floor, such floor has the characteristic of relatively getting close to nature, and owing to be pure woodwork, material is warm in nature, and feel is good, there is not radioactivity, burst size of methanal reaches E1 even higher level, to human body without any harm, yet with the floor price comparison costliness of pure log processing, meet water or tan by the sun etc. all may be out of shape, and being not easy to arrange becomes the main cause that people are reluctant to use wooden floor.

On the other hand, when local slab integral adopts a slice Wood Processing, to having relatively high expectations of material, and in fact, influence just its top layer of flooring look, if just top layer 3-5 millimeter adopts decorative pattern timber more attractive in appearance, middle other lower-cost material of changing can effectively reduce cost.

Summary of the invention

The utility model purpose provides a kind of double-decker and constitutes, and on-deformable double-decker wooden floor is to reduce the cost on floor.

For achieving the above object, the technical solution adopted in the utility model is: a kind of double-decker wooden floor, constitute by the strip plank, described plank constitutes top-down the compacting by decorative layer and bearing course of thickness direction, on every pair of side parallel to each other of plank, be respectively equipped with the tenon-tongue-and-groove structure of working in coordination, described decorative layer adopts the plates of solid wood of sawing or slicing, thickness is between 2 millimeters to 8 millimeters, its machine direction is consistent with length direction, the batten that described bearing course is arranged by the lateral separation constitutes, and adjacent batten spacing is between 1 millimeter to 3 millimeters.

During making, blank is made in two-layer process gluing, hot pressing (or colding pressing), passes through balancing of stresses, mechanical sanding, mortise, oiling (lacquer) again, promptly obtains required double-decker wooden floor.

This wooden floor can also be applied to other multi-layer floor, and thereunder binding equilibrium layer or other layer use again.

In the technique scheme, the density of wood of described bearing course is 0.4～0.8 gram per centimeter ³, thickness is greater than decorative layer, and each batten width is at 25 millimeters to 50 millimeters.

In the technique scheme, the direction of wooden fibers of described bearing course and the direction of wooden fibers of decorative layer are arranged vertically.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model bearing course is arranged by the batten lateral separation constitutes, fully separately do not have splicing between batten, thereby expanding with heat and contract with cold or humidity when changing, the problem of the cracking that is difficult for deforming;

2. the utility model decorative layer adopts precious plates of solid wood, obtains good result, and bearing course then adopts soft, medium-hard timber, both can reduce the floor echo, also can reduce the floor cost.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: referring to accompanying drawing 1, shown in 2, a kind of double-decker wooden floor, constitute by strip plank 1, described plank 1 constitutes top-down the compacting by decorative layer 2 and bearing course 3 of thickness direction, on plank 1 every pair of side parallel to each other, be respectively equipped with the tenon-tongue-and-groove structure 4 of working in coordination, described decorative layer 2 adopts the plates of solid wood of sawing or slicing, thickness is 4 millimeters, its machine direction is consistent with length direction, the batten 5 that described bearing course 3 is arranged by the lateral separation constitutes, each batten 5 width is 30 millimeters, and thickness is 12 millimeters, and adjacent batten 5 spacings are 2 millimeters.

It is 0.4～0.8 gram per centimeter that the bearing course of present embodiment adopts density of wood ³Soft, medium hardness timber, the direction of wooden fibers of direction of wooden fibers and decorative layer is arranged vertically.

Embodiment two: a kind of double-decker wooden floor, constitute by the strip plank, described plank constitutes top-down the compacting by decorative layer and bearing course of thickness direction, on every pair of side parallel to each other of plank, be respectively equipped with the tenon-tongue-and-groove structure of working in coordination, described decorative layer adopts the plates of solid wood of sawing or slicing, thickness is between 2 millimeters to 8 millimeters, its machine direction is consistent with length direction, the batten that described bearing course is arranged by the lateral separation constitutes, and adjacent batten spacing is between 1 millimeter to 3 millimeters.The density of wood of described bearing course is 0.4～0.8 gram per centimeter ³, thickness is greater than decorative layer, and each batten width is at 25 millimeters to 50 millimeters.

Claims
