Abstract

The utility model discloses a kind of anti-deformation dovetail wooden floor, be bonded by floor surface, floor solid wood layer, floor solid wood balance layer successively, described floor solid wood layer has many uniform dovetail grooves in interval in cross-sectional direction hollow out, is combined with the horizontal bolt of trapezoidal solid wood in described dovetail groove.The utility model passes through cross section hollow out in middle floor solid wood layer, coordinate again the horizontal bolt of solid wood, effectively cut off the fiber of solid wood, prevent the variation shrinkage strain of solid wood because of external environment, dovetail formula connects the consolidation more that coordinates that makes dovetail groove and the horizontal bolt of trapezoidal solid wood, thus more difficult distortion; Also reduced bonding needed wood glue amount between solid wood board and solid wood board, effectively protected IAQ (indoor air quality) simultaneously.

Description

A kind of anti-deformation dovetail wooden floor

Technical field

The utility model relates to finishing material field, relates in particular to a kind of anti-deformation dovetail wooden floor that is applied in flooring finishing.

Background technology

In house decoration, need to lay earth material, general conventional ceramic tile, wooden floor and plastic floor are as the material of laying ground, wooden floor is that natural timber is through open, the floor decorative material forming after processing, have pollution-free, decorative pattern nature, elegant noble, rich tactile sensation, the advantages such as elasticity is true, it is the preferred material of floor covering layers in current house decoration, natural wood texture and color and luster pattern that it presents give nature, the soft texture that is rich in affinity, simultaneously because it is cool in summer and warm in winter, the characteristic that sense of touch is good, the floor laying out is to the more gentle suitable sensation of people, it is a kind of ideal material of laying ground.

The wooden floor of prior art is all generally that multi-layer solid wood is glued together layer by layer by wood glue, because plank itself has fibre structure, run into water or wet air, or when expanding with heat and contract with cold, be easily out of shape along with the contraction of wood fibre, and the wood glue amount of the bonding needs of multi-layer solid wood is larger, as everyone knows, in glue, contain a large amount of formaldehyde, the invisible increase content of formaldehyde of wood glue amount conference, shines into room air pollution.

Summary of the invention

For addressing the above problem, the utility model provide a kind of simple in structure, be difficult for deforming, lay solid wood floor board with deformation-preventing easily.

The utility model is by the following technical solutions: a kind of anti-deformation dovetail wooden floor, be bonded by floor surface, floor solid wood layer, floor solid wood balance layer successively, described floor solid wood layer has many uniform dovetail grooves in interval in cross-sectional direction hollow out, is combined with the horizontal bolt of trapezoidal solid wood in described dovetail groove.

Preferably, the fit system of described dovetail groove and the horizontal bolt of described trapezoidal solid wood is interference fit.

Preferably, the width of the upper surface of described dovetail groove is greater than the width of soffit, and the soffit of soffit and described floor solid wood layer is positioned at same plane.

Preferably, the height of described dovetail groove be described floor solid wood layer height 1/2nd to 2/3rds.

Preferably, described floor solid wood layer is pine, and described floor surface and floor solid wood balance layer are masson pine bark.

Preferably, the thickness of described floor solid wood layer is 20mm, and the thickness of described floor surface and floor solid wood balance layer is 2mm, and the height of described dovetail groove is 12mm.

Compared with prior art, the utlity model has following beneficial effect: the utility model passes through cross section hollow out in middle floor solid wood layer, coordinate again the horizontal bolt of solid wood, effectively cut off the fiber of solid wood, prevent the variation shrinkage strain of solid wood because of external environment, dovetail formula connects the consolidation more that coordinates that makes dovetail groove and the horizontal bolt of trapezoidal solid wood, thus more difficult distortion; Also reduced bonding needed wood glue amount between solid wood board and solid wood board, effectively protected IAQ (indoor air quality) simultaneously.

Brief description of the drawings

Fig. 1 is stereogram of the present utility model;

Fig. 2 is decomposing schematic representation of the present utility model;

Wherein: 1, floor surface, 2, floor solid wood layer, 3, floor solid wood balance layer, 21, dovetail groove, 22, the horizontal bolt of trapezoidal solid wood.

Detailed description of the invention

Describe by the following examples the utility model, should be noted that, cited embodiment should not understand the restriction to utility model.

As depicted in figs. 1 and 2, a kind of anti-deformation dovetail wooden floor, successively by floor surface 1, floor solid wood layer 2, floor solid wood balance layer 3 is bonded, described floor solid wood layer 2 has four uniform dovetail grooves 21 in interval in cross-sectional direction hollow out, the height of described dovetail groove 21 be described floor solid wood layer 2 height 3/5ths, the soffit of the soffit of described dovetail groove 21 and described floor solid wood layer 2 is positioned at same plane, the horizontal bolt 22 of trapezoidal solid wood has closely cooperated in described dovetail groove 21, described dovetail groove 21 is interference fit with the fit system of the horizontal bolt 22 of described trapezoidal solid wood, such design has effectively been cut off the fiber of solid wood, prevent that solid wood from not changing shrinkage strain because of external environment.

Above-mentioned anti-deformation dovetail wooden floor, wherein, described floor surface is the masson pine bark that 2mm is thick, and described floor solid wood layer is the pine that 20mm is thick, and described floor solid wood balance layer is the masson pine bark that 2mm is thick, and three is bonding by wood glue successively.

In the present embodiment, dovetail groove can also be two, three, five even many, and the quantity of dovetail groove can specifically arrange as the case may be.

Obviously, foregoing is just for feature of the present utility model is described, and the not restriction to utility model, the variation that the those of ordinary skill in relevant technologies field is made in corresponding technical field according to the utility model should belong to protection category of the present utility model.
