Bamboo wood original state regular polygon recombined material and method for producing the same

Abstract

The invention provides a bamboo original state multiparty recombination material, which is characterized in that the external surface of the position of bamboo segment with equivalent diameter are processed into regular polygonal bamboo units; bamboo recombination material is obtained by arranging the bamboo units in parallel by the edges of the cross sections, vertical finger joint and prolonged bonding. The basic manufacturing method comprises the sawing of segments, milling of regular polygons, milling of finger tenons, glue application and assembly, compression and heating, cold solidification and other working procedures. The edges of the regular polygonal bamboo units range from four to eight. The bamboo original state multiparty recombination material has the advantages that bamboo has the physical structural characteristics of hollowness, conicity and bamboo joint; by arranging the hollow bamboo units in parallel by the edges and extending vertically at will, the recombination material maintains the natural structure of bamboo, and structural material with high strength, long length and large span can be manufactured; the material can replace wood, improve the utilization ration of bamboo, save forest resources, and can replace concrete, steel and other structural materials in certain usages, and the natural-intimate ability of structural material is improved.

Description

technical field [0001] The invention relates to an original multi-party recombined bamboo material and a manufacturing method thereof, belonging to the field of materials. Background technique [0002] my country is rich in bamboo resources and is the world's largest bamboo resource country. Bamboo has the characteristics of rapid growth, short rotation period, hollow bamboo joints, strong shear resistance, and excellent physical properties. Recombining hollow bamboo into composite materials that can replace wood can make full use of the original structure and physical properties of bamboo. Processed into environmentally friendly green materials, effectively alleviating the contradiction between my country's timber supply and demand. 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,...

AI Technical Summary

Problems solved by technology

The disadvantages and shortcomings of this technology are: cutting the arc-shaped bamboo blanks into square strips, resulting in a large amount of waste of raw materials, and the general utilization rate of bamboo is less than 30%.

The disadvantages and deficiencies of this technology are: 1) the texture of natural bamboo is damaged to varying degrees; 2) tiny gaps are easily formed inside bamboo boards or bamboo squares, which affects the quality of the section

The disadvantages and shortcomings of this technology are: 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

The disadvantages and shortcomings of this technology are: since the material is made of superimposed curved bamboo slices, it does not take advantage of the natural structure of the internal hollow and bamboo partitions of the bamboo, so it is very uneconomical to manufacture large columns or beams

[0007] The above four bamboo recombination technologies do not fully reflect the structural and physical characteristics of bamboo itself, the mechanical properties per unit mass are not high, and the requirements for long-range and large-span reorganization cannot be realized, so they cannot be used for mechanical strength, length, Structural materials with high span requirements
