Composite column made of whole bamboo tube and filled with filler and production process

Abstract

The invention provides a composite column made of a whole bamboo tube and filled with filler. A whole joint is cut off according to the length requirement, and after inner segments and tabasheer are removed, the filler is subjected to glue mixing and the bamboo tube after removal of the inner segments and tabasheer is filled with the filler; and when filling the filler, the outer circle of the bamboo tube is first clamped (to prevent the bamboo tube from burst when the filler is pressed), the small end of the bamboo tube is blocked, the bamboo tube is filled with the filler from the big end, the whole bamboo tube is filled and pressed tightly, and then the composite column made of the whole bamboo tube and filled with wood chips is manufactured. The composite column can be used as a standcolumn in a building construction or as a decorative material, maintains the original appearance characteristics of the bamboo tube, and has an excellent anti-pressure ability.

Description

technical field [0001] The invention relates to the field of supporting building structures made of whole bamboo without cracks, in particular to a composite column made of whole bamboo tubes filled with fillers and a production process thereof. Background technique [0002] my country is the main bamboo-producing country in the world, with an area of ​​about 4 million hectares of bamboo forest 2 , accounting for more than 90% of the world's moso bamboo production. my country's bamboo forest area accounts for about 0.5% of the country's land area, accounting for about 2.9% of the national forest area, and about 500 million moso bamboos can be cut down every year, equivalent to 10 million m 3 above wood. my country's bamboo forest resources are mainly distributed in the hilly and mountainous areas of 14 provinces, municipalities, and autonomous regions south of the Yellow River and the Yangtze River. As long as scientific management is carried out, these resources are inex...

AI Technical Summary

Problems solved by technology

[0004] 1. Most wood processing equipment and technologies cannot be directly applied in bamboo processing, so the technical level of bamboo processing industry is far behind that of wood processing industry

[0005] 2. Due to the special structure of bamboo, most products processed by bamboo can only be mechanized, and it is difficult to get rid of manual labor for individual processes or products. It is more difficult to achieve continuity and automation, so the labor production efficiency of bamboo processing industry is low

[0006] 3. The bamboo green on the outside of the bamboo and the yellow on the inside cannot be wetted by the adhesive, and the properties of the bamboo in the middle layer are also very different. The material that can be used in bamboo processing is the middle part, so the utilization rate of bamboo is low. According to The utilization rate of different products is mostly between 20% and 50%.

[0007] 4. Bamboo is difficult to be processed into large-sized boards or squares like wood through simple processing; bamboo can only be processed into widths of 20-30mm and thicknesses of 5-8mm through sawing, cutting or planing The bamboo chips are difficult to use directly

[0009] In the construction process, it is often necessary to set up corresponding columns. These columns often have high requirements for compression resistance, and the columns made of columns often have high compression resistance. However, due to the above reasons in actual use, the performance and strength Often still not enough, the production process needs to be improved for this reason, the applicant therefore applies for a composite column made of a whole bamboo tube filled with fillers and the production process
