New anti-corrosion refractory column

Abstract

The invention discloses a novel anti-corrosion and refractory column, which comprises a hollow active powder concrete pipe and carbon fiber cloth wound outside the active powder concrete pipe; the hollow cavity of the active powder concrete pipe is filled with ordinary concrete; the active powder concrete pipe The thickness of the base wall is 1 / 10 to 1 / 20 of its diameter; the two ends of the active powder concrete pipe are glued with carbon fiber cloth through high-strength bonding glue. The invention avoids the corrosion problem of the existing steel pipe concrete structure, improves the durability of the column, and at the same time reduces the energy consumption and maintenance cost of the existing column; utilizes the high tensile performance of carbon fiber and the high compressive performance of active powder concrete , and make the structure in the process of use, both reactive powder concrete and ordinary concrete are in a three-dimensional compression state, making full use of the performance of the material and saving costs; taking advantage of the high volume temperature stability of reactive powder concrete at high temperatures, ensuring In case of fire, the bearing capacity and performance of the structure.

Description

technical field [0001] The invention relates to the field of construction engineering pressure-bearing structures, specifically a novel anti-corrosion and fire-resistant column. Background technique [0002] With the continuous development of society and the advancement of science and technology, people have put forward higher requirements for the living transportation environment, comfortable housing, and office conditions. The construction industry, as the construction of the above-mentioned environment, bears a considerable part of the responsibility, especially in terms of fast, efficient and safe construction, and ensuring high quality and high quantity of buildings. [0003] When it comes to the construction industry, the contribution of concrete is indispensable, especially the existing steel pipe concrete structure has been widely used in the field of engineering structures, but the corrosion of the outer steel pipe, the disappearance of the outer hoop of the outer s...
