Abstract

The utility model discloses a core-board comprising a panel and a soleplate assembled by a plurality of battens whose length is equal with the core-board adhesively pressed along the longitudinal direction. Each batten is assembled by a plurality of small wood blocks with equal width adhesively connected along the transverse direction. The utility model can sufficiently make use of small diameter, bending and soft wood, the residue of the wood or the residual deforestation wood to manufacture the panel and the soleplate to improve the utilization rate of the wood. Meanwhile the scars and the worm holes on the wood and other defects also can be eliminated to enable the bottom surface and the panel to be more beautiful.

Description

A kind of core-board

Technical field

The utility model relates to a kind of core-board.

Background technology

Existing core-board is five laminates, the central layer that is positioned at the intermediate layer be by the wide wooden unit of polylith earlier behind the isometric batten of horizontally-spliced one-tenth and core-board again with batten longitudinally glue laminated be combined into, wooden unit is formed through sawing by materials such as log, short and small rim charge and rotary-cut reels, and face, base plate and the veneer that is positioned at the central layer levels all are whole the veneers that log forms by the peeler rotary-cut.Rotary cut venner must be made raw material with the big or middle footpath material of diameter more than 24cm, and its material wants hard, and it is straight that timber is wanted, and wooden soft timber (as China fir), the timber and the curved timber of minor diameter all can not be used the peeler rotary-cut, make that the utilization rate of timber is lower.On the other hand, most of timber itself have defectives such as knot, small holes caused by worms, and the veneer after the rotary-cut just has knot, small holes caused by worms, and such veneer will influence the outward appearance of core-board as being used as panel.Along with the decline of quality grade of structural timber situation and the shortage of big or middle footpath material raw material, the production of core-board is had a strong impact in recent years.

The utility model content

The utility model aims to provide the core-board of a kind of timber utilization rate height, good looking appearance.

The technical scheme that utility model adopted is: a kind of core-board, comprise panel, base plate, central layer, central layer is positioned at the intermediate layer, it is characterized in that: panel and base plate be by the isometric batten of many length and core-board longitudinally glue laminated be combined into, described batten is to be combined into along laterally glueing joint by the wide wood particle of polylith, between adjacent batten on the batten position of seam stagger mutually.

Batten is to be combined into along horizontal toe joint by the wide wood particle of polylith on described, base plate, is positioned at wood particle one end indention end to end, and the wood particle that is positioned at interlude is held indention end to end.

Described core-board is made up of panel, base plate and core plate three-layer, on the central layer on the orientation of wooden unit and face, the base plate orientation of wooden unit vertical, between adjacent batten on the batten position of seam stagger mutually.

The beneficial effects of the utility model are: one, since panel and base plate be by the isometric batten of many length and core-board longitudinally glue laminated be combined into, batten is to be combined into along laterally glueing joint by the wide wood particle of polylith, therefore can make full use of timber with small diameter, curved timber, soft wood, timber leftover pieces or timber felling residue, obtain wood particle by mode with the saw saw, be spliced into a veneer again, improve the utilization rate of timber.Two, can remove defectives such as knot, small holes caused by worms, make the end, panel more attractive in appearance.Three, the two ends of wood particle are done be stitched together after the toothing and can increase bonding plane between the wooden unit, increase bonding strength, make the anti-deformation of the end, panel good.

The specific embodiment

The structure of an embodiment of the utility model, as shown in Figure 1 and Figure 2, this core-board is made up of panel 1, central layer 2, base plate 3.Panel 1 and base plate 3 be by the isometric batten of many length and core-board longitudinally glue laminated be combined into, batten is to be combined into along horizontal toe joint by the wide wood particle of polylith, be positioned at wood particle 4 foremost and be positioned at an end indention of the wood particle 6 of least significant end, the wood particle 5 that is positioned at interlude is held indention end to end, between the adjacent batten on the batten position of seam stagger mutually.Central layer 2 also is to be formed by parquet, on the orientation of its wood particle and the end, the panel orientation of wooden unit vertical, promptly wide parquet becomes batten, many battens are along transversely arranged, between the adjacent batten on the batten position of seam stagger mutually.

The manufacture craft of face, base plate is as follows: with circular saw or band saw with timber leftover pieces or timber felling residue be sawn into more than the wide 4cm, the wood particle of thick 0.6cm, after the wood particle oven dry, become the equal wooden unit of width with the four side moulder power blader, with rack shaper the end end to end of wood particle is left saw shape tooth again, gluing on saw shape tooth, then the wood particle butt joint is combined into the rectangular of 2.5m length, behind rectangular four side moulder power blader excessively, at rectangular side gluing, be combined into panel and the base plate that 1.25m is wide, 2.5m is long with the jigsaw machine.

The manufacture craft of central layer is as follows: with circular saw or band saw with timber leftover pieces or timber felling residue be sawn into more than the wide 3cm, the wood particle of thick 1.0cm, after the wood particle oven dry, become the equal wooden unit of width with the four side moulder power blader, with wood particle side gluing, be combined into the plate that 1.25m is wide, 2.5m is long with the jigsaw machine, then plate is sawn into two halves along its length, is combined into the central layer that 1.25m is wide, 2.5m is long.

With central layer upper and lower surface gluing, cover upper plate and panel, after the last hot press compression moulding, be sawn into required size with Sawing machine, again the end, panel are promptly obtained the finished product core-board through abrasive finishing machine abrasive finishing.

Claims

1, a kind of core-board, comprise panel, base plate, central layer, central layer is positioned at the intermediate layer, it is characterized in that: panel and base plate be by the isometric batten of many length and core-board longitudinally glue laminated be combined into, described batten is to be combined into along laterally glueing joint by the wide wood particle of polylith, between adjacent batten on the batten position of seam stagger mutually.

2, core-board according to claim 1, it is characterized in that: batten is to be combined into along horizontal toe joint by the wide wood particle of polylith on described, base plate, be positioned at wood particle one end indention end to end, the wood particle that is positioned at interlude is held indention end to end.
