Novel anti-corrosion fire-resisting column
The invention discloses a novel anti-corrosion fire-resisting column. The novel anti-corrosion fire-resisting column comprises a hollow active powder concrete pipe and carbon fiber cloth which winds the active powder concrete pipe; ordinary concrete is filled in the hollow cavity of the active powder concrete pipe; the base wall thickness of the active powder concrete pipe is 1/10-1/20 of the diameter thereof; the pipe walls of two ends of the active powder concrete pipe are bonded with carbon fiber cloth through high-intensity cohesive glue. The novel anti-corrosion fire-resisting column avoids the corrosion problem of an existing steel pipe concrete structure, enables the durability of the column to be improved and enables the energy consumption and maintenance cost of an existing column to be lowered; the novel anti-corrosion fire-resisting column uses the high tensile resistance of the carbon fiber and the high pressure resistance of the active powder concrete, when using, both the active powder concrete and ordinary concrete are located at a three-dimensional compression state, the performance of the material is completely used, and the cost is saved; by means of the high volume-stability of the active powder concrete under a high temperature, the bearing ability and use performance of the structure are guaranteed in the case of fire.
