Strengthened concrete column structure with anticorrosion and anti-fire functions

Abstract

The invention discloses a strengthened concrete column structure with anticorrosion and anti-fire functions. The strengthened concrete column structure comprises sealing gum, a high-strength anti-crack anti-leakage shell, a separating anti-fire material, a rock wool board, fiber-reinforced-material-filled concrete and shearing pins. The concrete column structure is sequentially provided with the sealing gum, the high-strength anti-crack anti-leakage shell, the separating anti-fire material, the rock wool board and the fiber-reinforced-material-filled concrete from outside to inside; the separating anti-fire material is internally provided with a plurality of fixing ribs, and the shearing pins are inserted into the fiber-reinforced-material-filled concrete from the sealing gum. The strengthened concrete column structure with the anticorrosion and anti-fire functions has the advantages of being good in anticorrosion performance, earthquake resistance and durability, large in bearing capacity and high in anti-fire function, the anti-fire capacity of the concrete column structure is furthest improved, disasters generated by fire are remarkably reduced, an earthquake response of a building structure is reduced, the good protection effect on the building structure is achieved, and the strengthened concrete column structure is of great significance in building of the field of buildingstructure vibration control.

Description

technical field [0001] The invention belongs to the field of structural engineering, in particular to a reinforced concrete column structure with anti-corrosion and fire-proof functions. Background technique [0002] Concrete is currently the most widely used and used building material, especially in coastal areas, where there are a large number of concrete structures. There are many factors that may cause the performance degradation of concrete materials, especially under the erosion of coastal warm and humid air currents, the aging phenomenon of concrete structures is very serious. The problem of durability damage to building structures has become increasingly prominent, the ability to maintain the original performance of concrete for a long time has become weakened, and cracking and peeling of concrete are common. Among the many reasons that lead to the corrosion of steel bars in concrete, the carbonation of concrete and the erosion of chloride ions are the most importan...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a reinforced concrete column structure with both anti-corrosion and fire-proof functions, and provides a reinforced concrete column structure with good anti-corrosion performance, good shock resistance, good durability, large bearing capacity, and strong fire-proof function. The concrete column structure can overcome the problems of severe corrosion of buildings and insufficient anti-corrosion measures due to the limited thickness of the concrete protective layer of concrete structural members in areas such as coastal areas and high-salt areas. It not only solves the problems of poor ductility and insufficient durability of traditional concrete structural members In addition, it maximizes the fire resistance of the concrete column structure, significantly reduces the disaster caused by fire, and at the same time reduces the seismic response of the building structure, which plays a very good role in protecting the building structure.
