Fabricated FRP-sea sand concrete sound insulation and noise reduction wallboard

Abstract

The invention discloses a fabricated FRP-sea sand concrete sound insulation and noise reduction wallboard. The wallboard comprises FRP grids, FRP ribs, a high-ductility fiber reinforced sea sand cement-based composite material, sea sand concrete, sound absorption cotton 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 sound insulation and noise reduction layer, wherein the FRP grids and the vertical and horizontal FRP ribs are planted in the two sides of the high-ductility fiber reinforced sea sand cement-based composite material layer; and the vertical and horizontal FRP bars on the two sides are connected through the connecting pieces at part of crossed joints. The fabricated sound insulation and noise reduction wallboard has the characteristics of easiness in standardization of structural form, convenience in transportation, construction and installation, sound insulation, noise reduction, corrosion resistance, high lateral stiffness, high flexural rigidity and the like, has good adaptability in severe environments such as coastal sea, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of structural engineering new materials and combined structure applications, in particular to an assembled FRP-sea sand concrete sound-insulating and noise-reducing wallboard. 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 const...
