Abstract

The utility model discloses a composite wooden board, which is formed by adhesion of a standing wood layer formed by the close packing of polygonal standing wood blocks whose tangential sections are mutually adhesional and a wood bark layer formed by more than two layers of wood barks. The composite wooden board has two kinds, one is with a single bark surface, and the other is with double bark surfaces. The utility model has high intensity, and is uneasy to deform after long-time use. The board is rot-proof, waterproof, vermin proof, abrasion-proof and flame-proof after the bark is chemically treated. The utility model can be widely used in the fields of construction, furniture, decoration, etc.

Description

Composite wood board

The utility model relates to a kind of construction material, particularly a kind of wooden boards.

Timber be a kind of three-dimensional (fiber to, tangent line to, radius to) three sections (cross section, radial longitudinal section, tangential section) anisotropy material, to different sections and service orientation, its mechanical-physical character is significantly different.Existing timber-work uses with radial longitudinal section and tangential section and the form of depositing usually, and fibre guide is inconsistent.Like this, timber-work moisture absorption in use or drying are with regard to easy deformation, cracking.

The purpose of this utility model is to provide the permanent use of a kind of warp on-deformable wooden boards.

The purpose of this utility model is achieved in that and has designed a kind of composite wood board that is made of wooden cortex and standing tree layer, interlayer has adhesive, the composite wood board that said wooden cortex and standing tree layer constitute, interlayer has adhesive, the wood cortex is made of with the overwood skin two-layer, and interlayer has adhesive, and the prismatic wooden unit of polygon that the standing tree layer is fitted mutually by tangential section constitutes, between the wooden unit tangential section adhesive is arranged, the wooden unit tangential section is vertical with wooden cortex.

The standing tree layer both ends of the surface of the utility model composite wood board can all have wooden cortex, use to make multiple building materials, also can have only one of end face that wooden cortex is arranged, to do floor etc.

In order to guarantee the intensity of composite wood board, and be easy to process amalgamation, preferably adopt positive six prismatic wooden units to form the standing tree layers.

The utility model composite wood board is according to the guidance quality on the timber mechanics, it is bonding that the tangential section of the wooden unit of forming the standing tree layer is close to, and radial longitudinal section and wooden cortex are bonding, and shrinkage ratio, compression ratio, tension such as compare at the mechanical and physical performance unanimity in the same way to make it, bulk strength improves, and is not yielding.After testing, the existing wooden boards of its rupture strength has improved more than 2.5 times, and coefficient of elasticity has improved more than 20 times; Compression strength has improved more than 6.5 times.In order to improve plate property, the wooden skin that constitutes wooden cortex also can use slicing wood skin except that using volume to cut the wooden skin, and wooden skin is permeated processing with macromolecular material and fire retardant, makes sheet material anticorrosion, and waterproof is wear-resisting, fire-retardant.

Embodiment further specifies the utility model below in conjunction with accompanying drawing.

Fig. 1 is the structure chart of one of the utility model embodiment single-skin drum face composite wood board floor tile.

Fig. 2 is the standing tree layer structural representation of composite board.

Fig. 3 is the structure chart of the two surface composite wood boards of another embodiment of the utility model.

As shown in Figure 1, outer wooden skin 4 is arranged through the adhesive 3 bonding wooden cortexes that are composited with by regular hexagon standing tree piece 5 by orthogonal fiber orientation with internal layer wood skin 2 and is bonded into composite board with the adhesive 6 bonding standing tree layers that form.The suitable floor tile of doing of this sheet material.Standing tree layer shown in Figure 2 is bonded with adhesive 6 by regular hexagon standing tree piece 5.

As shown in Figure 3, the two surface composite wood boards of another embodiment of the present utility model all post wooden cortex by the two sides that regular hexagon standing tree piece 5 sticks with glue the agent 3 bonding standing tree layers of forming, the internal layer wood skin 2 of wooden cortex and outer wooden skin 4 through adhesive 3 and 1 and standing tree piece 5 bonding.The thickness of composite board can be different different because of the length of standing tree 3.This pair of surface composite wood board can be made door-plate, furniture etc.
