Problems solved by technology

Disadvantages and deficiencies: cutting arc-shaped bamboo blanks into square strips leads to a lot of waste of raw materials, and the utilization rate of moso bamboo is generally less than 30%.
Disadvantages and deficiencies: 1) The texture of natural bamboo is damaged to varying degrees; 2) Small gaps are easily formed inside bamboo boards or bamboo squares, which affects the quality of the section
Disadvantages and deficiencies: the macrostructure of natural bamboo is destroyed, the "original state" of bamboo is lost, the surface quality is not good, and it cannot replace higher-grade solid wood

Embodiment 1

[0036] Referring to Figures 1-9, according to the different diameters of the bamboo, the bamboo is split into curved bamboo blanks of a certain specification, and the inner and outer bamboo joints are removed by milling, and the "standard curved" bamboo blanks with the same specifications and smooth surface are processed. , one end or double short milling finger tenon. Then arc-shaped anastomosis is superimposed and glued to form a board, or a second reorganization is made to form a square material. Specific steps are as follows:

[0037] (1) Cut the moso bamboo into standard sections with a length of 500-3000 mm according to the diameter, taper, wall thickness and straightness of the bamboo. The bamboo splitting machine is used to split the round bamboo into arc-shaped blanks.

[0038] Specifications: Length: 500~3000mm

[0039] Width: 20~60mm

[0040] Thickness: natural wall thickness of bamboo

[0041] (2) Milling the bamboo green surface and the bamboo yellow surface ...

Abstract

It relates to the arc shape bamboo wood original status restructuring material. It is made by arc bamboo plates with smooth inside and outside compressing and sticking along the same direction. It maintains the natural structure of the bamboo wood with high strength restructured material. It can replace many precious wood and all kinds of artificial board. It improves bamboo wood utilization rate and saves this particular resource.

Description

technical field [0001] The invention relates to an original recombined arc-shaped bamboo material and a manufacturing method thereof, belonging to the field of materials. Background technique [0002] my country is the world's largest bamboo resource country. Bamboo has the characteristics of rapid growth and short rotation period. Processing hollow bamboo into composite materials that can replace wood can effectively alleviate the contradiction between supply and demand of wood in my country. Existing bamboo recombination technologies mainly include: [0003] (1) Bamboo recombination technology: split the hollow bamboo into arc-shaped bamboo blanks, then process the bamboo blanks into bamboo square strips of a certain specification, and glue the bamboo square strips together to form bamboo boards or bamboo squares. Disadvantages and deficiencies: Cutting arc-shaped bamboo blanks into square strips results in a lot of waste of raw materials, and the utilization rate of mos...
