Abstract

A plywood block relates to a wood product serving as a bearing structure part. The plywood block fills a blank in the prior art, adopts fast growing wood as a raw material to replace top grade solid wood, and comprises a plurality of wood single-boards. The plywood block is composed of at least two plate blanks which are integrally glued and stacked, each plate blank is formed by the plurality of wood single-boards in a glued and stacked mode, the thickness of the plate blanks is 20-40mm, and the density is 0.75-1.10g/mm3. The plywood block solves a problem that a 'core' portion of the plywood block cannot be tightly pressed when the thickness is large (more than 40mm), the plywood block adopts layering manufacture, namely firstly the plate blank with the thickness which can be tightly pressed is manufactured, and the plate blanks are then pressed to be manufactured products with the thickness of more than 40mm. During pressing, the fast growing wood with low density is pressed to be the products with high density, so that the strength of the products is improved. In addition, due to the fact that loads in different directions are loaded during use, the single-boards forming the plate blanks are arranged to be slope, slope direction of each plate blank is different, so that the loads in different directions are loaded.

Description

Glued board side

Technical field

The utility model relates to a kind of timber-work as load-bearing structural member.

Background technology

As the timber-work of load-bearing structural member, tradition generally is to adopt solid wood to make; But rare along with the forest reserves makes use cost progressively increase, and is unfavorable for protecting the rare forest reserves.In recent years, along with development of technology, released products such as density board, glued board, science and technology wood, bamboo offset plate at the timber-work manufacture field and arisen at the historic moment.But this type sheet material thickness maximum generally speaking can only reach 40mm, because surpass this thickness, adds man-hour in hot pressing, outside and " core " portion meeting appearance temperature, the uneven phenomenon of pressure.Therefore the said goods can not substitute the wooden structure part with large-size fully, like beam, post etc.Its intensity of the formed fast growing wood of fast growing wood industry, the density that grow up simultaneously nearly decades also is difficult to satisfy the requirement of big load load-bearing.

The utility model content

The utility model provides a kind of prior art blank of filling up to above problem, adopts fast growing wood to make raw material, can substitute the glued board side of high-grade solid wood.

The technical scheme of the utility model is: comprise some Wooden veneers, said plate side is made up of the slab that at least two cementing layers are stacked as one; Said slab is cascaded by some said Wooden veneer gummeds; Said slab thickness is 20-40mm, and density is 0.75-1.10g/mm ³.

The end face of said veneer and said slab is 20-70 ° of angle and is obliquely installed.

In the said plate side in the upper and lower adjacent slab incline direction of veneer opposite.

" core " portion pressed the not disadvantage of " reality " when the utility model (surpassed 40mm) greatly for solving thickness, adopted layering processing, promptly was processed into the slab that can press " reality " thickness earlier, slab was suppressed again, and then was made the product above 40mm thickness.And when compacting, the low-density fast growing wood is pressed into high density product, makes that the intensity of product is bigger.In addition, consider the load of carrying different directions when utilizing, the veneer that the utility model also constitutes slab is set to, and the incline direction between each slab is different, the feasible load that can carry all directions.

Fig. 2 is the structural representation of the utility model,

Fig. 3 is the left view of Fig. 2;

1 is plate side among the figure, the 11st, and slab, the 110th, veneer, the 111st, end face.

The specific embodiment

The plate side of the utility model 1 comprises some Wooden veneers 110 shown in Fig. 1-3, said plate side 1 is made up of the slab 11 that at least two cementing layers are stacked as one; Said slab 11 is cascaded by some said Wooden veneer 110 gummeds; Said slab 11 thickness are 20-40mm, and density is 0.75-1.10g/mm ³.

The end face 111 of said veneer 110 and said slab 11 is 20-70 ° of angle and is obliquely installed.

In the said plate side 1 in the upper and lower adjacent slab 1 incline direction of veneer 110 opposite.After this sample product is cut to beam, post from vertical branch (that is: cross section is a herringbone), nail all can be eaten in four sides.

The product of the utility model is mainly used in: composite floor board panel, blank, and door, window, door pocket, the load-bearing beam column, furniture, and form the OSB solid wooden compound floor with OSB gummed.

Claims (3)

1. glued board side comprises some Wooden veneers, it is characterized in that, said plate side is made up of the slab that at least two cementing layers are stacked as one; Said slab is cascaded by some said Wooden veneer gummeds; Said slab thickness is 20-40mm, and density is 0.75-1.10g/mm ³.

2. glued board side according to claim 1 is characterized in that, the end face of said veneer and said slab is 20-70 ° of angle and is obliquely installed.

3. glued board side according to claim 2 is characterized in that, in the said plate side in the upper and lower adjacent slab incline direction of veneer opposite.
