Abstract

A layered bamboo plate includes longitudinal layer (4), and transverse layers (5) and wood glue (3) wait each one.Longitudinal layer is glued together with wood glue (3) by vertical bamboo branch (1) to form, and transverse layers is glued together with wood glue (3) by horizontal bamboo branch (2) to form.In when combination, longitudinal layer is folded in turn alternately mutually with transverse layers, and makes the bamboo branch of the bamboo branch of longitudinal layer and transverse layers orthogonal, uses wood glue (3) that each laminating is closed then and forms.

Description

Layered bamboo plate

The growth of trees, the diameter of its trunk, the increase of pressing annual ring is and continuous cumulative big, and And is formed solid result thus, so since ancient times, just changes places very much and is sawn into plank, is applied on the various purposes.

The invention of wooden splint is the mat lathe does the wood of diameters,,, cutting sheet is sticked together with glue again and forms after obtaining continuously thin slice along its garden week planing with lathe tool.Because technical difficulty, wood is done last core and often can not be arrived below the diameter four English inch.

The growth of bamboo is with thick bamboo tube from bottom to top, and the Zhi Jing And of bamboo pole does not have horizontal expansion.Because innately be that genus is hollow, diameter is again little simultaneously, can not be sawn into plate, extremely difficult again method for making of imitating wooden splint is so that the product of bamboo clappers not to be arranged so far yet.

The high-toughness fibres that bamboo had in fact, the wood that actual specific is general is more winning, if it can be made into plate, it is lighter or stronger than plank to be bound to, best be exactly maturity period of bamboo be 2 to 6 years approximately, and the fastest non-ten several years of trees to the many decades of growth can not be become a useful person, dual trouble time that increases day by day in world forest day by day withered thirsty (the especially forest of diameters) and demand, the timber of necessary for human must substitute by the dependence bamboo wood from now on.For China, populous, the soil deficiency, modernization is urgent required in order to build a large amount of timber of house, furniture and product etc., more non-pecuniary in time can the purchase, moreover annual every mu of fiber growth rate of bamboo is two to six times of general trees approximately, and its influence is extremely great on economic interests.

Because bamboo and woody be exactly the plant of sibling species not; except trunk diameter, fiber, color and striped have great difference; their planting method, harvesting method and Protection Code all respectively have lattice of one's own; machinery after the harvest or chemical treatment; even the process of making or processing is all the same not to the utmost; therefore present wood products such as wooden splint (Plywoods) laminated wood (Laminate Woods) force fit plate (Wafer Woods) and particieboard (Particle Boards) etc., must not with the present invention's Ti And opinion Xiang.

In order to break through above-mentioned difficulty and the utilization of bamboo wood to be brought into play greatly, purpose of the present invention is exactly earlier the bamboo branch to be utilized wood glue to make two kinds of vertical and horizontal thin slices, and then with longitudinal and transverse veneering, make the bamboo clappers of stratiform, to substitute present plank or wooden splint etc., make the purposes of various kinds.

Though this layered bamboo plate principle is made up of the bamboo branch, can also be according to principle of uniformity, with the material replacement of wood branch or other strips.

This Zhu Ban And can add the material that covers other outside changing its appearance, or promotes its purposes.

Detailed situation and other advantages can be from following accompanying drawing and explanations and learn.

Fig. 1 is a side view of the present invention.

Fig. 2 is a top view of the present invention, wherein in turn every layer part is cut open, to show inner situation.

Fig. 3 is a front view of the present invention.

The present invention is the longitudinal layer of being made up of vertical bamboo branch (1) (4), the transverse layers (5) that horizontal bamboo branch (2) is formed, and wood glue (3) is formed.

Vertically bamboo branch (1) be cross section from bamboo pole longitudinally cut with sharp sword and must the bamboo branch, in view of the geometry of bamboo pole annular cross section special, cut the bamboo branch, its Heng Jie Mian And is not limited to rectangle, also may be trapezoidal, triangle or other shape.

Laterally the method for making of bamboo branch (2) is identical with vertical bamboo branch (1), but its length, shape and size can be different with vertical bamboo branch.

When combination, vertical bamboo branch (1) is neat flat raft earlier, with wood glue (3) it is sticked to form flat thin longitudinal layer (4), and laterally bamboo branch (2) is also complied with method and formed flat thin transverse layers (5).And then longitudinal layer and transverse layers is folded mutually alternately, with wood glue (3) each laminating is closed and to form, when folded mutually, the bamboo branch of each longitudinal layer must be orthogonal with the bamboo branch of transverse layers, but the total number of plies behind the number of plies of longitudinal layer and transverse layers and the composition then can be any.

This layered bamboo plate such as purely each bamboo branch is all formed along same direction by longitudinal layer, or when longitudinal layer and transverse layers are folded mutually,, then can make the usefulness of bamboo Beam or bamboo post with the ratio minimizing of all parallel phase Fang ， of bamboo branch And with width and thickness.

Though the method for making of above-mentioned layered bamboo plate is different with other artificial wooden plate And, the industrial technology of some planks can improve slightly, is applied in the present invention.

Claims

1, a layered bamboo plate is characterized in that: with wood glue uniform bamboo branch flat raft is pasted mutually earlier and form longitudinal layer and transverse layers, then that longitudinal layer and transverse layers is folded mutually, with wood glue each laminating is closed again and forms, but when folded mutually the bamboo branch of longitudinal layer, must be orthogonal with the bamboo branch of transverse layers.

2, the described bamboo clappers of claim 1, can become bamboo Beam or bamboo post, as long as it is triangle, trapezoidal or irregular shape that the cross section of bamboo branch has some, it is characterized in that: only select longitudinal layer to fold mutually and make each bamboo branch all along same direction, or when longitudinal layer and transverse layers are folded mutually, make the bamboo branch of each layer all parallel to each other.

3, the described bamboo clappers of claim 1, the feature of its appearance is: add and covered some other material such as cured, paper, paint, plastics, chemical glue, thin metal or veneer etc.

4, the described invention of claim 1, its another feature is: form the bamboo branch of each layer, available wood branch replaces, or generation is with material such as rattan class, reed, jowar, straw, straw and the fiber crops branch etc. of other strips, as long as contained fiber all is along same direction.

5, the method for making of a layered bamboo plate is characterized in that comprising following program:

(1) bamboo pole is longitudinally cut with sharp sword, to obtain uniform bamboo branch.

(2) with the neat flat raft of described bamboo branch, with wood glue with it gummed to obtain flat thin rectangular longitudinal layer.

(3) with the neat flat raft of described bamboo branch, with wood glue it gummed is its width to obtain flat thin rectangular transverse layers ， And with the length of described longitudinal layer, the width of described longitudinal layer is its length.

(4) described longitudinal layer and transverse layers interaction is folded, make the bamboo branch of longitudinal layer orthogonal at Die Shi And mutually with the bamboo branch of transverse layers, with wood glue each laminating is closed then, with the bamboo clappers product of acquisition rectangle stratiform.
