Abstract

The invention discloses a wooden thin plate overcoming the defect that the traditional wooden thin plate takes large-caliber raw woods as raw materials. The wooden thin plate comprises wood splints with equal widths and thicknesses, the abutting ends of the wood splints are in finger joint along the directions of wood grains; tenon fingers (11) are symmetrical with tenon grooves (12); the end surfaces of the tenon grooves (12) of two wood splints are attached with adhesives and are jogged and wedged to become a finger joint wood (1); the side surface of the finger joint wood (1) is attached with the adhesives and adhered with an another finger joint wood so as to form a single-layer assembly (2); the single-layer assembly (2) is a width-reducing thickness-reducing plate (4); and the side surface (31) of the width-reducing thickness-reducing plate (4) is attached with the adhesives and then adhered with an another width-reducing thickness-reducing plate to be spliced into the wooden thin plate (5). The invention takes small-diameter woods as the raw materials to ensure small woods for great use and high increment; the invention enhances the wooden bonding strength of products through structures, thereby overcoming the inherent defects of easy cracking and bending strain of original woods and also enhancing the combination properties, i.e. compressive resistance, bending resistance, nail holding, and the like; and in addition, the invention reduces the dependence on large-caliber natural forests, thereby having the social benefits of ecological environment protection.

Description

A kind of wooden thin plate

Technical field

The present invention relates to a kind of wooden profile material

Background technology

Traditional wooden large stretch of thin plate, be to form with bigbore rounding flakiness and gummed, it is to the dependence of heavy caliber wildwood, cause the felling wildwood to destroy the situation of ecological environment, as how undersized log, mountain firewood time material, short and small material, timber processing residue leftover pieces are raw material, make large stretch of wooden thin plate, make small wood become big usefulness, be only the environmental protection behave that reduces the felling wildwood and ensure market supply and demand, keep ecological balance.The present invention to the patent No. is: the extension of the patent of invention of ZL 200720004370.8 " a kind of wooden profile material ".

Summary of the invention

The object of the present invention is to provide a kind of is raw material with undersized log, mountain firewood time material, short and small material, timber processing residue leftover pieces, and structure is connected into large stretch of wooden thin plate.

For achieving the above object, described wooden thin plate is made up of batten sheet wide, uniform thickness, and its technical scheme is: direction along the grain, the butt end of batten sheet becomes finger joint, its tenon refers to be symmetry shape with the tenon ditch, and the tenon ditch end face of two batten sheets becomes finger wood with adhesive and stick wedging; Finger wood side is the individual layer assembly with adhesive and bonding another finger wood; Individual layer assembly along the grain direction saw is separated to subtracting wide plate, will subtract wide plate and saw thin being again and subtract the reductions slab; The described side that subtracts the reductions slab behind the adhesive bonding another and subtracts the reductions slab and be spliced into wooden thin plate.

Its beneficial effect is:

One, does raw material with undersized log, make large stretch of wooden thin plate, make small wood become big then self-evident with, its appreciation.

Two, the overall structure of combination woodwork, its wood fibre is through, the latitude shape that interweaves, improved internal bond strength, it is easy to crack and scratch the inherent shortcoming of change to have overcome timber, has also improved resistance to compression, bending resistance, has held combination property such as nail, strengthens the mechanical strength of timber-work effectively, thereby, improved product quality,, more showed its importance veneer!

Three, can satisfy the demand of raw materials market, can reduce dependence again, have the social benefit of preserving the ecological environment the heavy caliber wildwood.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the batten sheet is wide through deburring, behind the thicknesser uniform thickness, direction along the grain, the butt end of batten sheet becomes finger joint, its tenon refers to that (11) and tenon ditch (12) are symmetry shape, tenon ditch (12) end face of two batten sheets becomes finger wood (1) with adhesive and stick wedging; Finger wood (1) side is individual layer assembly (2) with adhesive and bonding another finger wood; Individual layer assembly (2) along the grain direction saw is separated to subtracting wide plate (3), makes it to follow the specified limit for width of plane sawing machine, will subtract wide plate (3) and saw thin being again and subtract reductions slab (4); The described side (31) that subtracts reductions slab (4) behind the adhesive bonding another and subtracts the reductions slab and be spliced into wooden thin plate (5).

As improvement of the present invention, referring to Fig. 3, Fig. 4, the described wide plate (3) that subtracts has at least a side to be scarf (31).For strengthening the intensity of recombinant multiple connection, the described reductions slab (4) that subtracts is spliced into wooden thin plate (5) mutually with its scarf (31).

As another kind of improvement the of the present invention, referring to Fig. 6, with individual layer assembly (2) as the intermediate layer, its upper and lower plate face adhesive and is laminated wooden thin plate (5) respectively at the upper and lower plates face, the grain direction of middle individual layer assembly (2) layer wooden thin plate upper and lower with it (5) right angle each other is staggered, get the plank of desired thickness, width, length, become the wooden thin plate of multiple layer combination (6).
