Problems solved by technology

[0002] my country is the country with the largest bamboo resources in the world. The bamboo processing industry has developed rapidly, but the utilization rate of bamboo is very low. Taking bamboo flooring as an example, the utilization rate of whole bamboo is less than 25%.
Its disadvantages and deficiencies are: the arc-shaped bamboo blanks are cut into square strips, resulting in a lot of waste of raw materials, and the general utilization rate is less than 30%.
Although the utilization rate of this kind of reorganization is higher than that of rectangular reorganization, it still has the following disadvantages and defi

Example Embodiment

[0059] Example 1:

[0060] figure 1 For the manufacturing process of the trapezoidal bamboo material in its original state of the present invention, the moso bamboo with a diameter at breast height of 80-120mm is selected as the basic material, and the round bamboo is split into arc-shaped bamboo blanks of certain specifications according to the different diameters of bamboo materials. figure 2 As shown, after milling and processing into a standard trapezoidal cross-section bamboo board with consistent specifications (see image 3 ), one end or double end milling finger tenon, according to the set finger joint bamboo board as the set length. Then arrange and stack the blanks and glue them into a sheet, or recombine them twice to form a square lumber. Specific steps are as follows:

[0061] (1) According to the diameter, taper, wall thickness and straightness of the bamboo, the moso bamboo is sawed into standard sections with a length of 500-2000mm. Use a bamboo breaking machine t...

[0087] Example 2:

[0088] Reference Figure 1 ~ Figure 3 , Image 6 As shown, large-size dragon bamboo with a diameter at breast height of 100-200mm is selected as the basic material. According to the different diameters of bamboo, the round bamboo is split into arc-shaped bamboo blanks of certain specifications, and then milled into standard trapezoidal bamboo boards with the same specifications. Double short milling finger tenon. Then arrange the blanks and superimpose the glue to synthesize materials with various geometric shapes, or recombine them to form larger square timbers. Specific steps are as follows:

[0089] (1) According to the diameter, taper, wall thickness and straightness of the bamboo, the dragon bamboo is sawed into standard sections with a length of 100-3000mm. Use a bamboo breaking machine to split the round bamboo into arc-shaped bamboo blanks.

Abstract

The invention relates to a ladder-shaped bamboo original state recombined material and a manufacturing method thereof, which belong to the field of materials. The ladder-shaped bamboo original state recombined material is formed by orderly arranging and splicing smooth ladder-shaped bamboo boards which take bamboo outers as ladder-shaped upper bases and bamboo inners as ladder-shaped lower bases; and the ladder-shaped bamboo boards can take the shape of an isosceles trapezoid or a non-isosceles trapezoid. The ladder-shaped bamboo original state recombined material has the advantages: a rounded hollow bamboo slab is processed into the ladder-shaped bamboo board so as to carry out original state bamboo slab recombination on the basis of keeping the natural structure of the bamboo according to characteristics of hollowness and cone-shape of the bamboo and large differences of the bamboo outers, the bamboo inners and bamboo joints in terms of the metal property and the like; compared with the traditional rectangular (square) combination, the utilization rate is increased due to the original state combination; multiple geometric figure recombination can be realized, and the recombined bamboo material with high strength can be manufactured. The ladder-shaped bamboo original state recombined material can be used for replacing precious woods and various artificial slabs. The utilization rate of the bamboo resources is increased, and wood resources are saved. The invention also provides a manufacturing method of the recombined material.

Description

technical field [0001] The invention belongs to the field of materials, and relates to an original recombined material of trapezoidal bamboo, and also relates to a manufacturing method of the recombined material. Background technique [0002] my country is the world's largest bamboo resource-rich country. The bamboo processing industry has developed rapidly, but the utilization rate of bamboo is very low. Taking bamboo flooring as an example, the utilization rate of whole bamboo is less than 25%. Bamboo has the characteristics of rapid growth and short rotation period. Processing hollow bamboo into new composite materials has a good application prospect. Existing bamboo recombination technologies mainly include: [0003] (1) Rectangular recombination technology: Split the hollow bamboo into arc-shaped bamboo blanks (such as figure 2 shown), and then the bamboo blank is processed into a rectangular (or square) strip of a certain specification (such as Figure 4b As shown),...
