Raw bamboo structural component partially reinforced by adopting fiber reinforced plastics (FRP) and manufacturing method thereof

Abstract

The invention discloses a raw bamboo structural component partially reinforced by adopting fiber reinforced plastics (FRP) and a manufacturing method thereof. The raw bamboo structural component partially reinforced by adopting the fiber reinforced plastics comprises a raw bamboo tube, a fiber reinforced plastic outer coating layer, a shear pin, and a sealing layer, wherein an internal cavity is defined in the raw bamboo tube; the fiber reinforced plastic outer coating layer is arranged outside the raw bamboo tube and comprises resin, fiber, and an inner filling material; the inner filling material is arranged in the inner cavity; the shear pin penetrates through the inner filling material and the raw bamboo tube and is used for limiting the position of the inner filling material; and thesealing layer is arranged in the inner cavity and is located at the at least one end of the inner filling material in the length direction. The extension of cracks on the raw bamboo tube can be effectively suppressed, and meanwhile the bearing capacity and deformation capacity of the raw bamboo tube are greatly improved, so that the raw bamboo structural component partially reinforced by adoptingthe fiber reinforced plastics has a relatively stable mechanical property, is corrosion-resistant and is prevented from suffering air shrinkage.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an original bamboo structural component partially reinforced by FRP and a manufacturing method thereof. Background technique [0002] In related technologies, China is one of the central bamboo production areas in the world, and the bamboo forest area accounts for a quarter of the global bamboo planting area. Bamboo has a short growth cycle and significant carbon sequestration, making it a green and environmentally friendly ecological building material. The full use of bamboo can alleviate the plight of timber shortage, reduce the use of traditional non-environmental protection building materials, and promote the construction of ecological civilization. The original bamboo structure is a common structural form of bamboo. The unyielding, noble and elegant cultural connotation contained in the original bamboo structure makes it common in various domestic landscape designs. In th...

AI Technical Summary

Problems solved by technology

The steel hoop can slightly increase the compressive and shear strength along the grain in a short period of time, but as the original bamboo structure shrinks, the stress of the steel hoop relaxes, and the restraining effect is poor

At the same time, the steel hoop has poor corrosion resistance and is prone to corrosion fracture
