Manufacturing method of thin-wall steel pipe confined bamboo member

Abstract

The invention relates to a manufacturing method of a thin-wall steel pipe confined bamboo member. The manufacturing method of the thin-wall steel pipe confined bamboo member comprises the steps that acore bamboo material is formed by docking a constant section bamboo material section with a wedged end head, a jacking pipe is mounted, a thin wall steel pipe is placed, a variable section sleeve ismounted, the core bamboo material is embedded, ajack is pressed downward, the variable section sleeve and the jackingpipe are removed, and the member is ground, and the thin-wall steel pipe confined bamboo member is formed. The core bamboo material is composed of the constant section bamboo material section and the wedged end head, and the wedged end head, the thin-wall steel pipe, the variable section sleeve and the jacking pipe can be reused. According to the manufacturing method of the thin-wall steel pipe confined bamboo member, the core bamboo material with cross section size being slightly larger than the inner diameter of the thin-wall steel pipe being pressed in the thin-wall is realized through the lap joint of the variable section sleeve and the thin-wall steel pipe and the arrangement of the wedged end head of the core bamboo material. The bearing capacity and deformation capacity of a single bamboo material in the process of using are effectively improved, meanwhile, the existence of the steel pipe further avoids a brittle failure mode of the core bamboo material, and the manufacturing method of the thin-wall steel pipe confined bamboo membercan be widely used in beams,columns and other members in the civil engineering field.

Description

Technical field [0001] The invention belongs to the field of civil engineering, and specifically relates to a manufacturing method of a composite member, in particular to a manufacturing method of a thin-walled steel pipe restraining bamboo member. Background technique [0002] At present, most of the building structures in my country use brick-concrete structures and reinforced concrete structures, which require the use of a large amount of clay products, cement and steel. These building materials have high energy consumption, high pollution, difficult to degrade after being abandoned, poor thermal insulation performance, and earthquake resistance. Defects such as poor performance. In the current environment of developing a low-carbon economy, green, ecological, and environmentally friendly new building structural materials are the inevitable direction of the development of civil engineering technology. Bamboo is one of the current varieties of environmentally friendly materials...

AI Technical Summary

Problems solved by technology

[0004] The research on steel-pipe-confined concrete structures has a long history and mature technology. Steel pipes can provide continuous circumferential restraint to the core concrete, making the concrete in a three-dimensional compression state, improving its bearing capacity and deformation capacity, and avoiding brittle failure of concrete. It also avoids the inward buckling of the steel pipe, but the concrete has the disadvantages of self-heaviness and high energy consumption
