Abstract
Disclosed is a solid wood plywood which belongs to a plywood, in particular to a substrate material of a solid wood composite floorboard. The deflection and flatness of the current solid wood plywood are not ideal, while the solid wood composite plywood of the utility model is composed of a plurality of layers of rigid and mixed solid wood boards, and the contact surfaces are coated with environment friendly adhesive for bonding. The utility model is characterized in that a plurality of wood fibre score breaks are arranged in the direction presenting 45 degrees - 70 degrees between one face or two faces of the board and the wood fibre grains. The solid wood plywood has advantages of good deflection and flatness performance, environment protection, firmness and durability, and can resist the change of outside condition.
Description
Technical field
The utility model belongs to a kind of glued board, especially a kind of solid wooden compound floor base material.
Background technology
The base material of known solid wooden compound floor mostly is common glued board, according to the design thickness of glued board, adopts moisture content less than 12% the crisscross assembly of hardwood sheet material, through colding pressing, hot pressing, surface sands flat, the type of being sawn into is made again.The yield rate of the glued board of this explained hereafter of pressing normal plywood is low, and the deflection degree of 80% product, glacing flatness, environmental protection effect aspect all do not reach requirement.A kind of assembling plywood (patent No.: 200520112190.2) disclose and a kind ofly constitute uniform thickness or many groups glued boards of forming of some groups of glued boards gummed of uniform thickness not, the crisscross assembly of every group multi-layered board by multi-layered board is arranged at present.Its deflection degree of this assembling plywood and glacing flatness are better, and can satisfy the requirement of environmental protection aspect, the corresponding raising of yield rate.But this assembling plywood is in extraneous environmental change; the deflection degree and the glacing flatness of be heated, catch a cold, the back glued board is steeped in water logging are still not ideal enough; and this assembling plywood needs earlier sheet material to be glued together assembly and then will organize the glued board gummed more; therefore the sheet material environmental protection glue number of times that is heated has increased once; it is few more good more that common environmental protection glue is heated, and can not surpass 3 times, and the number of times that is heated increases the character that changes glue easily; thereby influence its bonding strength, and then influenced the service life of glued board.
Summary of the invention
Technical problem to be solved in the utility model is to make the glued wood plate that good deflection degree and glacing flatness be arranged, and a kind of environmental protection is provided, and good glacing flatness and deflection degree are arranged, and can resist external environment and change a kind of glued wood plate of firm and durable.
This glued wood plate is made up of the assorted firmly solid wood board of multilayer, and its contact-making surface is coated with the environmental protection gluing and closes, it is characterized in that sheet material one or both sides and lumber fibre lines at 45～70 ° of directions have some lumber fibre marks of break.
By longitudinal grin sheet material with band sheet material is crisscross forms, promptly the sheet material length direction is parallel with the lumber fibre direction is band sheet material to this glued wood plate by the assorted firmly solid wood board of multilayer, and the sheet material length direction is vertical with the lumber fibre direction to be longitudinal grin sheet material; Its contact-making surface is coated with the environmental protection gluing and closes and form.
When sheet material lumber fibre lines mark of break face was single face, adjacent two boards material mark of break face can be relatively or contrarily or is made up the mark of break face is relative with the one side of no mark of break, and its contact-making surface is coated with the environmental protection gluing and closes and form.
The degree of depth of this glued wood wood plate fiber mark of break is that 1/2 of sheet metal thickness is advisable, and cut will be drawn protruding end too deeply, too shallowly can not well reach desirable deflection degree and glacing flatness.
The sheet material of selecting for use is single, and consistency of thickness, moisture content are less than 12%, and then the deflection degree of glued board and glacing flatness are better.
The utility model is made by solid wood, has possessed the advantage of wood floor, adopts the environmental protection gluing to close, and burst size of methanal is low, environmental protection.And glued board is crisscross, on sheet material, form the mark of break of intersecting with sheet material lumber fibre lines, can better eliminate stress when producing stress in extraneous environmental change, guarantee that glued board has good deflection degree and glacing flatness, effectively prevent the glued board warpage, and environmental protection glue only is heated once in sheet material gummed process, can better keep its character, to guarantee the service life of glued board.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the embodiment as shown in Figure 1,, adopt thickness to be 1.65mm according to the design thickness 1.5cm of glued board, 10 layers of the Eucalyptus sheet materials of moisture content 12%, wherein 5 layers sheet material is band sheet material 1, other 5 layers sheet material is longitudinal grin sheet material 2.At first on any one side of band sheet material 1 and longitudinal grin sheet material 2, form mark of break 4 with the cutter cutting-up with 3 one-tenth 70 ° of directions of sheet material lumber fibre lines, the degree of depth of mark of break is 1/2 of a sheet metal thickness, then band sheet material 1 there is the mark of break face relative with longitudinal grin sheet material 2 no mark of break faces, and band sheet material 1 and the 2 crisscross overlapping combinations of longitudinal grin sheet material, its contact-making surface is coated with the environmental protection gluing and closes, through hot pressing, cooling, surface sand flat and form the glued wood plate naturally.
Claims (5)
1. glued wood plate is made up of the assorted firmly solid wood board of multilayer, and its contact-making surface is coated with the environmental protection gluing and closes, it is characterized in that sheet material one or both sides and lumber fibre lines at 45～70 ° of directions have some lumber fibre marks of break.
2. a kind of glued wood plate as claimed in claim 1, it is characterized in that the assorted firmly solid wood board of multilayer is by longitudinal grin sheet material and the crisscross composition of line transverse slat material, be that the sheet material length direction is parallel with the lumber fibre direction for band sheet material, the sheet material length direction is vertical with the lumber fibre direction to be longitudinal grin sheet material; Its contact-making surface is coated with the environmental protection gluing and closes and form.
