Abstract
The utility model relates to a three-layer solid wood composite floor which belongs to the building material technology field. The three-layer solid wood composite floor is made of three layers of wood by hot pressing. In the structure, the floor is divided into a surface layer, a core layer and a bottom layer. The total thickness of the surface layer, the core layer and the bottom layer is 18-21mm. The thickness of the bottom layer is 4-6mm. The three-layer solid wood composite floor is the three-layer solid wood composite floor of 18mm which can be directly paved on a keel, solve the limitation that the common three-layer solid wood composite floors can only be paved on a plane and expand the scope of the installation and the application.
Description
Technical field
The utility model relates to a kind of three-layer wood composite flooring, belongs to building material technical field.
Background technology
Known three-layer wood composite flooring is meant with the plates of solid wood to be surface layer, the solid wood bar is a sandwich layer, veneer is the grooved and tongued floor that bottom is made, wherein skin depth is the 3-4 millimeter, core layer thickness is that 8-9 millimeter and base plate thickness are the 2-2.5 millimeter, and the floor gross thickness is at the three-layer wood composite flooring of 15 millimeters crisscross structure.What this three-layer wood composite flooring adopted when laying usually is floated shop method, promptly directly can be installed on the ground grading or keel add on the core-board.Common three-layer wood composite flooring is laid immediately on the high keel of frame, makes floor and ground that certain distance be arranged, and plays the effect of temperature isolation and ground grading to a certain extent, reduces the Yin Wendu deformation effect of project sound generation over the ground.Because the structural defective of common three-layer wood composite flooring, cause the MOR on floor and flexural strength not enough and can not load-bearing, can not adopt traditional single keel to set up method, reduce the installation applicability of three-layer wood composite flooring.
Summary of the invention
The utility model mainly is to solve the common three-layer wood composite flooring that exists in the prior art can not be laid immediately on limitation on the keel, changes the technical problem of deficiency etc. of the quiet bending resistance of common three-layer wood composite flooring.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of three-layer wood composite flooring is formed by three layers of timber wood hot pressing, is divided into top layer, sandwich layer, bottom from structure, and the gross thickness of described top layer, sandwich layer, bottom is 18 millimeters to 21 millimeters, and the thickness of described bottom is 4 millimeters to 6 millimeters.Described sandwich layer is a uniform thickness, wide and have a fast-growing Chinese fir bar of best flakiness ratio combination, and with the cross-under of natural wood glue line.
As preferably, the gross thickness of described top layer, sandwich layer, bottom is 18 millimeters, and the thickness of described bottom is 5 millimeters.
As preferably, there is the joint tongue and the tongue-and-groove of the combination that cooperatively interacts the two ends of described three-layer wood composite flooring, two sides.
As preferably, adopt two vertical and one horizontal wood composite structures between described top layer, sandwich layer, the bottom.
Therefore, 18 millimeters three-layer wood composite floorings of the utility model can be laid immediately on the keel, have solved common three-layer wood composite flooring and can only lay in the plane limitation, have enlarged the installation scope of application.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A-A amplification profile of accompanying drawing 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1 and Figure 2, three-layer wood composite flooring is formed through heat pressure adhesive by top layer 1, sandwich layer 2, bottom 3.Top layer 1 is a decorative layer, and multiselect is hard with quality, the seeds of beautiful texture.Sandwich layer 2 is spliced by the China fir sawn timber.Sandwich layer 2 is vertical with bottom 2 directions with top layer 1, forms two vertical and one horizontal wood composite structures.There is the joint tongue 4 and the tongue-and-groove 5 of the combination that cooperatively interacts the two ends of three-layer wood composite flooring, two sides.The gross thickness that its mesexine 1, sandwich layer 2, bottom are 3 three layers is 18 millimeters, and wherein bottom 3 is 5 millimeters.
It is described that the claimed scope of the utility model is not limited only to above embodiment, and the thickness of top layer, sandwich layer, bottom can be selected the size of other suitable type.
Claims (3)
1. three-layer wood composite flooring, form by three layers of timber wood hot pressing, be divided into top layer (1), sandwich layer (2), bottom (3) from structure, it is characterized in that: the gross thickness of described top layer (1), sandwich layer (2), bottom (3) is 18 millimeters to 21 millimeters, and the thickness of described bottom (3) is 4 millimeters to 6 millimeters.
