CN2132607Y - Small-diameter wood-core joinery board - Google Patents

Abstract

The utility model discloses a small-diameter wood-core joinery board, which belongs to a wood processing product; the utility model is composed of a core wooden board glued by building block style collecting standard blocks and a single board; the structure is characterized in that the upper and the lower both surfaces of the core wooden board are respectively pressed with a single board, and simultaneously, a thin wooden board is also pressed close to the two single boards respectively. A joinery board made according to the method can be sawn freely, and the strength is very high.

Description

Small-diameter wood-core joinery board

The utility model belongs to timber-work, and relates to the making of mosaic parquets ornamental blocks.

Common core-board is formed by central layer surface paste veneer veneer or veneer.The structure of central layer has following several at present: a kind of is to make long 200-800 millimeter with the timber saw, wide 25-40 millimeter, the batten of thick 10-20 millimeter, the central layer that staggered splicing becomes.Generally with the bigger timber processing of footpath level, because of the timber volume recovery of small diameter grade is low, useless edges of boards are too many in the making of this batten.Another kind of central layer is the stalk section that becomes the 10-20 millimeters long with crosscuts such as jowar stalk, Sunflower Stalk.Intensive being emitted on the veneer of stalk section that length is identical, end face and veneer gummed, by the table of upper and lower surface that the stalk section is glued together, form core-board.Between the central layer part stalk section of this core-board and the stalk section big slit is arranged, thus frame must be arranged when producing sheet material, and can not arbitrarily cut and use.Also having a kind of central layer is to make netted lattice or cellular glazing bar with paper or cardboard, overlays veneer up and down.This core-board more can not arbitrarily cut usefulness certainly, and its intensity is also poor.

The utility model is intended to utilize the forest zone to fell processing central layers such as brush wood, thinnings, the assorted shrub of path, the core-board that making can arbitrarily be cut and intensity is high.

The technical solution of the utility model is to realize like this, the calibrated bolck of the different shape that is pressed into wood waste, path brush wood, thinnings and assorted shrub, be bonded to the monoblock core plank of various cell cubes respectively, and then descend two sides pressing veneer and veneer successively thereon, make the core-board that this programme proposes.

The utility model accompanying drawing is explained:

Fig. 1 is the core-board cut-away structure chart that the trapezoidal strip wood glue core plank of forming and veneer and veneer combine for the utility model adopts the cross section.(1) is the core plank among the figure, and (2) are veneer, and (3) are veneer.

The core-board cut-away structure chart that Fig. 2 adopts core plank that four limit indent arc cylinders and cylinder gluing form and veneer and veneer to combine for the utility model.

The core-board cut-away structure chart that Fig. 3 core plank that positive hexagonal prism gluing forms for the utility model adopts and veneer and veneer combine.

Below in conjunction with accompanying drawing the utility model is explained in detail, the utility model is 90213058.7 in the patent No. " the building block system parquets decorate calibrated bolck " the basis on develop and form.Its elementary cell is a cylinder, and four limit indent arc cylinders are trapezoidal strip wood with sticking mutually body of cylinder and cross section.The classification of described unit is pasted and can be become seamless bulk board, and after planing, the upper and lower veneer that overlays promptly becomes core-board.See Fig. 2 and Fig. 3.

Another kind of plate cored structure is to be processed into the positive hexagonal prism of strip, longitudinally to cut open from the diagonal of end face, and becoming the cross section is trapezoidal strip wood, becomes the core plank as the splicing among Fig. 1 then, upper and lower overlay again veneer core-board.

For gaining in strength, but above-mentioned core-board in pressing pressing one deck veneer on the basis of veneer.

Adopting the cross section among Fig. 1 is that trapezoidal strip wooden unit splicing becomes core plank (1), its upper and lower surface overlay respectively a veneer (2) core-board, and then on each veneer (2), overlay a veneer (3), to strengthen its intensity.Core plank (1) among Fig. 2 is four limit indent arc cylinders and the sticking mutually bulk board that forms of cylinder, and the core plank (1) among Fig. 3 is the sticking mutually thin piece plate of positive hexagonal prism.

Core plank of the present utility model is the assembly of the different shape made by scoot because of what adopt, so saved the utilization rate of bulk sheet material.Because of the core plank is the integral body that is formed by some cell cube bondings, after planing processing, Paint Gloss smooth, behind the pressing veneer, sheet material is closely knit seamless, and can arbitrarily cut use again.

Claims (2)

1, a kind of path reel core-board is to be made of core plank and veneer, it is characterized in that core plank (1) is formed by building block system parquets calibrated bolck bonding, the upper and lower surface of core plank (a 1) veneer of each pressing (2), and adjacent two veneers (2) overlay a veneer (3) respectively.

2, path reel core-board according to claim 1 is characterized in that core plank (1) can be that the strip wood glue knot of ladder type forms by the cross section, can be formed by four limit indent arc cylinders and cylinder gluing, also can be formed by positive hexagonal prism gluing.
