Carbon fiber composite steel pipe concrete column and construction method thereof
The invention discloses a carbon fiber composite steel pipe concrete column and a construction method thereof. The concrete column includes a concrete column body. The end of the concrete column body is coated with a carbon fiber cloth formed carbon fiber cloth confining region, the outside of the concrete column body is also coated with a steel pipe formed steel pipe confining region, and the carbon fiber cloth confining region is adjacent to the steel pipe confining region. The carbon fiber cloth confining region at the end of the concrete column body provides circumferential constraining force to the concrete column. Carbon fiber cloth has good tension resistant, shear resistant and seismic reinforcement effects, but cannot be pressed, blocks transmission of axial force to the steel pipe confining region, thereby suppressing the effect of pressure on the steel pipe. The concrete column body part and the steel pipe confining region can be completed during pouring, and then carbon fiber cloth is sticked to form the carbon fiber cloth confining region so as to adapt to different shapes and adapt to the shortcomings of complex node structure, difficult construction and the like of steel pipe concrete columns.
