Abstract
The utility model discloses an allotypic unit integrated plate, which relates to a splice plate, and solves the problems that the existing leftover material of the lumber can not be fully used, the application range of the small diameter lumber is narrow, the utilization rate is low, the yield rate is low and the mechanical property is poor. The plate of the utility model is produced by splicing a bar lumber (1) with a right triangular cross section and a bar lumber (2) with a right triangular cross section in units. The utility model causes the leftover material of the lumber and the utilization rate of the small diameter lumber to achieve up to above 80 percent, and the yield rate achieve above 75 percent, and causes the leftover material of the lumber and the small diameter lumber products to become high added value products and non-structural or structural lumber with good performance from low added value products. The performance index is that the structural integrated lumber achieves the Notification 111 of the Ministry of Agriculture, forestry, fisheries of Japan structural integrated lumber standard; and the non-structural integrated lumber achieves the Notification 112 of the Ministry of Agriculture, forestry, fisheries of Japan non-structural integrated lumber standard. The leftover material of the lumber and the small diameter lumber can realize good use of inferior lumbers and great use of small lumbers, and thus the utility model can be widely used in the fields such as the furniture, the building, the interior decoration, etc.
Description
Technical field
The utility model relates to splicing sheet material.
Background technology
At present, the big footpath of China wildwood level high-quality timber resources is burst weary, and the leftover pieces waste of timber is serious, the substitute is the artificial forest fast growing wood, and artificial fast-growing woods area has reached first of the world.Because the artificial fast growing wood growth cycle is short, the footpath level is little, material difference and mechanical property are low.Craze and transfiguration very easily in dry run, qualification rate is low.So be used for producing the materials such as sandwich layer veneer, building form and purlin material for building of glued board more, make its range of application be subjected to bigger restriction.Adopt the leftover pieces of the method timber of traditional saw lumber to be not fully utilized, its volume recovery only is 60～65%.
The utility model content
The utility model is not fully utilized for the leftover pieces that solve existing timber, and the artificial fast growing wood range of application is narrow, and utilization rate is low, volume recovery is hanged down problems such as reaching poor mechanical property, and a kind of special-shaped unit circuit board is provided.The concrete technical scheme that addresses the above problem is as follows:
The utility model is that right angled triangle web 1 and cross section are the integrated bonding sheet materials of making in triangle web Unit 2 by the cross section, first cross section of sheet material left end side is that the inclined-plane of right angled triangle web 1-1 and inclined-plane that adjacent first cross section is the waist of triangle web 2-1 link together, first cross section is that the inclined-plane of another waist of triangle web 2-1 and adjacent cross section are that second cross section is that the inclined-plane of right angled triangle web 1-2 links together, the straight flange that the straight flange that second cross section is right angled triangle web 1-2 and the 3rd cross section are right angled triangle web 1-3 links together, the inclined-plane that the hypotenuse that the 3rd cross section is right angled triangle web 1-3 and second cross section are the waist of triangle web 2-2 links together, the cross section is that the inclined-plane of another waist of triangle web 2-2 and the hypotenuse that the 4th cross section is right angled triangle web 1-4 link together, the upper surface of sheet material is that the last plane that triangle web 2-1 and second cross section are triangle web 2-2 constitutes by first cross section, and the lower surface of sheet material is right angled triangle web 1-1 by first cross section, second cross section is right angled triangle web 1-2, the 3rd cross section is right angled triangle web 1-3 and the 4th the lower plane formation that the cross section is right angled triangle web 1-4.
It is that the different right angled triangle web 1 in cross section, cross section are different triangle web Unit 2, cross section that the utility model is processed into the cross section with the leftover pieces of timber or small dimension wood, adopt integrated splicing, make sheet material, the utilization rate that makes the leftover pieces of timber or small dimension wood is up to more than 85%, volume recovery is 75～80%, the leftover pieces of timber are utilized effectively, make the leftover pieces of timber and small dimension wood become high value added product and non-preferably structure of characteristic or structure material by low value-added product.Sheet material after testing, every performance indications: the structure integrated timber reaches " No. the 111st, Japanese Agriculture, Forestry and Fisheries Ministry bulletin " structure integrated timber standard; Non-structure integrated timber reaches " No. the 112nd, Japanese Agriculture, Forestry and Fisheries Ministry bulletin " non-structure integrated timber standard; Make the leftover pieces of timber or the purpose that small dimension wood is able to the big usefulness of small wood, the excellent usefulness of bad material.The integrated sheet material of its special-shaped unit can be widely used in fields such as furniture, building, interior decoration.
Description of drawings
Fig. 1 is the schematic cross-sectional view of right angled triangle web 1, and Fig. 2 is the schematic cross-sectional view of triangle web 2, and Fig. 3 is the overall structure schematic diagram of the specific embodiment one timber transect.
The specific embodiment
The specific embodiment one: describe present embodiment in conjunction with Fig. 1, it is that the different right angled triangle web 1 in cross section is the integrated bonding sheet materials of making in different triangle web Unit 2, cross section with the cross section that the leftover pieces of present embodiment employing timber or small dimension wood are sawn into the cross section, first cross section of sheet material left end side is that the inclined-plane of right angled triangle web 1-1 and inclined-plane that adjacent first cross section is the waist of triangle web 2-1 link together, first cross section is that the inclined-plane of another waist of triangle web 2-1 and adjacent cross section are that second cross section is that the inclined-plane of right angled triangle web 1-2 links together, the straight flange that the straight flange that second cross section is right angled triangle web 1-2 and the 3rd cross section are right angled triangle web 1-3 links together, the inclined-plane that the hypotenuse that the 3rd cross section is right angled triangle web 1-3 and second cross section are the waist of triangle web 2-2 links together, the cross section is that the inclined-plane of another waist of triangle web 2-2 and the hypotenuse that the 4th cross section is right angled triangle web 1-4 link together, the upper surface of sheet material is that the last plane that triangle web 2-1 and second cross section are triangle web 2-2 constitutes by first cross section, and the lower surface of sheet material is right angled triangle web 1-1 by first cross section, second cross section is right angled triangle web 1-2, the 3rd cross section is right angled triangle web 1-3 and the 4th the lower plane formation that the cross section is right angled triangle web 1-4.
Should guarantee during splicing that the upper and lower surface of sheet material is parallel.
The processing process: at first leftover pieces and the Logs of small diameter with timber blocks, adopting special-shaped sawing method to process the cross section by the shape (raising volume recovery) of leftover pieces and Logs of small diameter is that cross section different right angled triangle web 1-1,1-2,1-3,1-4 and cross section are the special-shaped unit material of cross section different triangle web 2-1,2-2, unit material makes it become perfectly straight special-shaped unit material through the laggard capable finger of super-dry, to improve the utilization rate and the volume recovery of timber leftover pieces and small dimension wood, make sheet material by the specific embodiment one described integrated bonding way then.
