HOLLOW BAMBOO STRIP, HOLLOW BAMBOO BOARD AND MANUFACTURING METHOD THEREOF

Abstract

A hollow bamboo strip includes mao bamboo sheets formed by splitting bamboo; the two sides of a mao bamboo sheet are cut with matching surfaces, thereby making a finished bamboo sheet with a trapezoidal cross section, the matching surfaces of a plurality of finished bamboo sheets are successively spliced or finger jointed into a hollow bamboo strip with a hollow structure. A hollow bamboo board is spliced by fitting several hollow bamboo strips at side surfaces. A method for manufacturing a hollow bamboo board includes: splitting the bamboo into several mao bamboo sheets in its peripheral direction; cutting a mao bamboo sheet into a finished bamboo sheet with a trapezoidal cross section; carbonizing the finished bamboo sheet; forming the finished bamboo sheets subjected to carbonization into a hollow bamboo strip; fitting corresponding side surfaces of several hollow bamboo strips to be spliced into a hollow bamboo board.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0026] In order to better set forth the present invention, the present invention will be explained below in detail in combination with the embodiments.

[0027] As shown in FIGS. 2-4, a hollow bamboo strip 3 consists of a plurality of finished bamboo sheets 2 with a trapezoidal cross section and a hollow structure. Such a structure has the advantage of material saving, and avoids the deformation of the hollow bamboo strips 2 due to its property of stress buffer.

[0028] Specifically, the cross section of the hollow bamboo strip 3 is a square (as shown in FIG. 4) or a regular hexagon. Such a structure may reserve the raw material to the greatest degree, has less waste of the bamboo sheet to be cut out, and is convenient to splice and combine the products subsequently.

[0029] As shown in FIGS. 5-6, a hollow bamboo board is formed by splicing the hollow bamboo strips 3 at side surfaces. Similarly, such a hollow bamboo board saves materials, has the characteristic of stress buffer and is not easily deformed.

[0030] Further, in other embodiments, the hollow bamboo strip 3 is filled with one or more of a thermal insulation material, a sound-proof material or a fire-proof material therein, so as to improve its overall performance.

[0031] As shown in FIGS. 1-6, a method for manufacturing a hollow bamboo board includes:

[0032] (1) splitting fresh bamboo into several mao bamboo sheets 1;

[0033] (2) cutting a mao bamboo sheet 1 into a finished bamboo sheet 2 with an isosceles trapezoidal cross section, with a bottom angle ranging from 40 to 70;

[0034] (3) carbonizing the finished bamboo sheet 2;

[0035] (4) subsequent to carbonization, forming the finished bamboo sheets 2 into a hollow bamboo strip 3;

[0036] (5) fitting side surfaces of the above hollow bamboo strips 3 to be spliced into a hollow bamboo board.

[0037] It is known from geometric knowledge that such a processing method can reserve the raw materials to the greatest extent, and reduce the waste to be cut out. Compared with the existing bamboo sheet with a rectangular cross section, its waste is much less, with considerable economic benefits for an enterprise with an output value of tens of millions.

[0038] The above embodiments are not taken as further limits to the present invention. Non-material modifications to the contents of the present invention made by persons skilled in the art shall fall within the protection scope of the present invention.
