Abstract

The invention discloses an assembled permanent formwork overlapped FRP rib seawater sea sand recycled concrete beam and a manufacturing method thereof. The assembled permanent formwork overlapped FRPrib seawater sea sand recycled concrete beam comprises a prefabricated assembled permanent formwork and an FRP rib seawater sea sand recycled concrete beam. The prefabricated assembled permanent formwork is formed by assembling corer strip assembly blocks, first panels, second panels and positioning connecting parts, and the formwork is manufactured from an engineering cement-based composite (ECC)and a fiber woven mesh. The FRP rib seawater sea sand recycled concrete beam comprises seawater sea sand recycled concrete poured into the prefabricated assembled permanent formwork and an FRP rib framework fixedly arranged in the seawater sea sand recycled concrete. As the TRE formwork and the FRP rib seawater sea sand recycled concrete are compounded, the engineering manufacturing cost of the formwork is effectively reduced, the ductility of the FRP rib seawater sea sand recycled concrete beam is improved, the long-time durability of FRP ribs is guaranteed, and meanwhile the problems that an existing integral formwork is large in occupied space and not easy to transport are solved.

Description

technical field [0001] The invention relates to an assembled permanent formwork laminated FRP bar seawater sea sand recycled concrete beam and a manufacturing method thereof, belonging to the technical fields of marine engineering structures, port structures, hydraulic structures and the like. Background technique [0002] Due to the increasingly depleted river sand resources and the necessity of ecological environment protection, coupled with transportation costs and construction period constraints, the necessity and importance of how to rationally and effectively utilize seawater and sea sand resources in marine engineering construction has become increasingly apparent. At the same time, using recycled aggregate as the raw material for concrete preparation can maximize the utilization of resources. [0003] Fiber Reinforced Polymer (FRP) bars have excellent properties such as light weight, high strength, corrosion resistance, and fatigue resistance, and are ideal substitut...
