Imitated bamboo recombinant bamboo column and preparation method thereof

Abstract

The invention relates to an imitated bamboo recombinant bamboo column. The imitated bamboo recombinant bamboo column comprises a recombinant bamboo column cylinder, a built-in pipe and wrapping FRP (Fiber Reinforce Plastic) reinforcing belts, wherein the built-in pipe is arranged inside the recombinant bamboo column cylinder, and is integrally connected with the recombinant bamboo column cylinder;the outside of the recombinant bamboo column cylinder is wrapped and reinforced with the FRP reinforcing belts at certain intervals; the FRP reinforcing belts are bonded with the recombinant bamboo column cylinder. By adopting the imitated bamboo recombinant bamboo column, a hollow recombinant member is reinforced by the built-in pipe and the FRP reinforcing belts, so that the carrying capacity,cracking resistance and buckling resistance of the hollow recombinant bamboo column are enhanced; by imitating the natural structure of original bamboo, the imitated bamboo recombinant bamboo column is simple and attractive in appearance and reasonable in stress, and can be directly taken as a stand column of buildings in scenic spots, holiday resorts and the like to realize perfect combination ofattractiveness and practicability; the hollow recombinant bamboo column can be taken as a building column.

Description

technical field [0001] The invention relates to a recombined bamboo product, in particular to a bamboo imitation recombined bamboo column and a preparation method thereof. Background technique [0002] Bamboo is a low-carbon and renewable biomass material with the advantages of high strength-to-weight ratio, light weight and earthquake resistance. It is a high-quality and potential structural material that can be used for load-bearing structures such as frame beams and columns. Recombined bamboo is a high-strength, high-density, and uniform engineering material obtained by deep processing of bamboo. The development of recombinant bamboo processing technology has greatly improved the utilization rate and production efficiency of bamboo. The cross-sectional size of recombined bamboo components is generally controlled by factors such as stiffness, stability, and bolt spacing in the node area. The material strength in the middle of the cross-section of solid components cannot be...

AI Technical Summary

Problems solved by technology

The cross-sectional size of the recombined bamboo member is generally controlled by factors such as stiffness, stability, and bolt spacing in the joint area. The material strength in the middle area of ​​the cross-section of the solid member is not fully utilized, which increases the weight of the structure and is not conducive to reducing the cost.

[0003] Due to the unidirectional nature of bamboo bundle fibers, the cross-grain strength of recombined bamboo is lower than the along-grain strength, and the hollow column has the risk of splitting in the direction along the grain. Orientation prone to split risk issues
