Abstract

The invention relates to a novel solid wood board, in particular to a deformation-preventing solid wood board. The deformation-preventing solid wood board is characterized by being formed by splicing and squeezing three layers, such as an upper layer, a middle layer and a lower layer, wherein the upper layer and the lower layer are solid wood lamina layers (1) and the middle layer is a solid wood slat layer (2) which is formed by splicing and squeezing long batten strips (21) side by side; the long batten strips (21) are formed by the finger joint of short wood batten strips (211); and finger-joint interfaces (212) on the adjacent long batten strips (21) are arranged in a staggering way. Due to the adoption of the structure that the solid wood slat layer is clamped by the two layers of solid wood lamina layers, the long batten strips at the middle layer become supporting rods of the wood board so as to effectively prevent the deformation of the wood board; and the long batten strips are formed by the finger joint of the short batten strips so that wastes are changed into valuables while thin and short woods are avoided from being wasted.

Description

A kind of distortion-free solid wood plank

Technical field

The present invention relates to a kind of novel solid wood timber, relate in particular to a kind of distortion-free solid wood plank.

Background technology

Along with improving constantly of living standard, people require also progressively to promote to the class of furniture, and wherein solid wood furniture especially is well received by consumers.Follow the progress of science and technology, contact between all parts of the world is more and more nearer, the fast-selling all parts of the world of the solid wood furniture of domestic product, brought a technical difficult problem also for simultaneously the solid wood furniture industry: because the temperature difference of different regions is big on the earth, humidity differs, the framework timber of solid wood furniture is very easy to cracking and distortion, thereby has destroyed the product phase of solid wood furniture, has brought great puzzlement for the solid wood furniture business and consumer.

Summary of the invention

The invention provides a kind of distortion-free solid wood plank, it is rational in infrastructure, and is firmly indeformable.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:

A kind of distortion-free solid wood plank is formed by three layers of bonding extruding of upper, middle and lower, and two-layer up and down is the solid wood thin plate layer, and the middle level is a solid wood bar flaggy; Described solid wood bar flaggy is formed by the bonding side by side extruding of long fillet.

Described long fillet is formed by short fillet finger, and the finger interface interlace on the adjacent long fillet is arranged;

Finger interface between the described short fillet is the zigzag interface, surperficial parallel towards with solid wood bar flaggy of sawtooth crown;

Bonding between the described finger interface with viscose glue.

Beneficial effect of the present invention is: owing to adopt the structure of two-layer solid wood thin plate layer folder solid wood bar flaggy, the long fillet in middle level becomes the brace rod of plank, has effectively prevented the distortion of plank; Long fillet is formed by short fillet finger, when avoiding thin billet to waste, also turns waste into wealth; The sawtooth interface of short fillet surperficial parallel towards with solid wood bar flaggy, the usefulness viscose glue is bonding between the interface, has further increased the anti-deformation intensity of plank.

Description of drawings

Fig. 1 is the sectional schematic diagram of a kind of distortion-free solid wood plank of the present invention;

Fig. 2 is the structural representation of solid wood bar flaggy 2 among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of distortion-free solid wood plank of the present invention is made detailed description:

As shown in Figure 1, solid wood plank of the present invention is formed by three layers of bonding extruding of upper, middle and lower, the upper and lower are solid wood thin plate layers 1, from the log timber of handling through anticracking, be sawn into the solid wood thin plate with special mechanical equipment, handle through fixed thick sanding, one-tenth thickness is 3 ~ 7 millimeters solid wood thin plate layer 1 eventually again, and solid wood thin plate layer 1 is solid wear-resisting, texture is happy naturally, and is attractive in appearance firm.The middle level is a solid wood bar flaggy 2, form by the bonding side by side extruding of the long fillet 21 of several specification standards, between the adjacent long fillet 21 with viscose glue 22 bonding after mechanical presses again, sanding is carried out on the surface after forming plank, solid wood bar flaggy 2.Two sides daub at solid wood bar flaggy 2 is stained with solid wood thin plate layer 1 respectively, carries out mechanical presses again, and drying has been made distortion-free solid wood plank of the present invention with the back.

As shown in Figure 2, the long fillet 21 of solid wood bar flaggy 2 is formed by short fillet 211 fingers, short fillet 211 is the weak point side's bars from the specification standards that are sawn into special equipment on the log timber of anticracking processing, also the thin billet of discarding can be processed into weak point side's bar of same specification standard, the finger interface 212 of two ends serrate that then will the side's of weak point bar, sawtooth is the isoceles triangle shape of symmetry, surperficial parallel towards with short fillet 211 itself of its symmetry axis, again to the 212 even applying glues of finger interface, to lack fillet 211 at last is stitched together by finger interface 212, mechanical compaction, the fillet 21 of promptly growing up after the drying.

Claims
