Prefabricated frp-sea sand concrete sound and noise reduction wall panel

Abstract

The invention discloses an assembled FRP-sea sand concrete sound insulation and noise reduction wall panel. The structure includes FRP grids, FRP bars, high ductility fiber reinforced sea sand cement-based composite materials, sea sand concrete, sound-absorbing cotton, and connectors. . The main body of the wall panel is composed of a high ductility fiber reinforced sea sand cement-based composite material layer with FRP grids and vertical and horizontal FRP bars implanted on both sides, and an internal sound insulation and noise reduction layer. The vertical and horizontal FRP bars on both sides are connected by connecting pieces at some intersection nodes. The prefabricated sound insulation and noise reduction wall panel is easy to standardize in structure, convenient for transportation, construction and installation, and has the characteristics of sound insulation and noise reduction, corrosion resistance, high lateral stiffness, high bending stiffness, etc., and has good performance in harsh environments such as coastal oceans. Adaptability, suitable for promotion and use.

Description

technical field [0001] The invention relates to the technical field of application of new materials and combined structures in structural engineering, in particular to a prefabricated FRP-sea sand concrete sound insulation and noise reduction 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 areas and islands and reefs, the marine environment is rich in chloride ions, which can cause corrosion of steel bars, affect the durability of reinforced concrete structures, and then damage the structures, causing economic losses and even endangering people's safety. Engineering construction in marine environments such as coastal areas and islands and reefs is far from 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 construction...
