Fabricated FRP-gradient sea sand concrete composite wallboard

Abstract

The invention discloses a fabricated FRP-gradient sea sand concrete combined wallboard. The combined wallboard comprises FRP grids, FRP ribs, a high-ductility fiber reinforced sea sand cement-based composite material, sea sand concrete and connecting pieces; a wallboard main body is composed of a high-ductility fiber reinforced sea sand cement-based composite material layer and an internal sea sand concrete layer, wherein the FRP grids, and the vertical and horizontal FRP bars are planted in the two sides of the high-ductility fiber reinforced sea sand cement-based composite material layer; and the vertical FRP bars and the horizontal FRP bars on the two sides are connected through the connecting pieces at part of crossed joints. According to the fabricated combined wallboard, the characteristics of light weight, high strength, corrosion resistance and the like of a FRP material and the advantage that the sea sand concrete can be obtained from local materials are fully utilized, so that the fabricated combined wallboard has the characteristics of easiness in standardization of the structural form, convenience in transportation, construction and installation, corrosion resistance, high bearing capacity, high lateral stiffness, high flexural rigidity and the like, has good adaptability in severe environments such as coastal ocean, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of new materials for structural engineering and the application of composite structures, in particular to an assembled FRP-gradient sea sand concrete composite wall panel. Background technique [0002] Reinforced concrete structure is one of the most common and widely used structural forms in the construction industry. However, in coastal and reef areas, the marine environment is rich in a large amount of chloride ions, which will cause corrosion of steel bars, affect the durability of reinforced concrete structures, and cause structural damage, resulting in economic losses and even endangering people's safety. Engineering construction in marine environments such as coastal areas and islands and reefs is far away from the inland, and resources such as fresh water and river sand are scarce. The use of traditional reinforced concrete structures has problems such as large material transportation, high construct...
