AI Technical Summary

Problems solved by technology

However, the ultra-high performance concrete shrinkage is relatively large, which causes the ultra-high performance concrete shell to easily produce fine cracks, which reduces the protection performance of the ultra-high performance concrete shell to the internal concrete
In addition, due to the thin UHPC shell layer, it is difficult to arrange stirrups, so that when the concrete column is under pressure, the UHPC shell will also expand laterally due to compression and produce fine cracks; this also reduces the ultra-high performance concrete. Protective properties of high performance concrete shells

Abstract

The invention discloses a concrete column and belongs to the technical field of building structures. The concrete column comprises a composite shell and common concrete poured into the composite shell. The composite shell is of a closed multi-layer composite structure and sequentially comprises an outside coating layer and an inside coating layer from outside to inside, an inner cavity is composedof the outside coating layer and the inside coating layer, ultra-high-performance concrete is poured into the inner cavity, and longitudinal supporting ribs are embedded in the ultra-high-performanceconcrete; and the outside coating layer and the inside coating layer are made of a fiber reinforced composite material. The composite structure of the concrete column is optimized, the service life can be prolonged, and cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a concrete column. Background technique [0002] Concrete columns are a common form of structural components, generally used as bridge piers or pile foundations in bridge structures, and are the main load-bearing components. Because most of the bridge piers and pile foundations are in a humid environment, ordinary concrete columns will be severely eroded, especially in sea or coastal areas, which will pose a serious threat to the safety of bridge structures. [0003] Ultra-high performance concrete is a new type of material, which has the characteristics of good ductility, high strength, and strong impermeability; the ultra-high performance concrete is used as the outer shell, and ordinary concrete is poured inside to form composite concrete columns to improve bridge piers or The ability of the pile foundation to resist the erosion of the external environment. Howev...
