Abstract

The invention discloses an assembleable permanent formwork laminated FRP rib seawater sea sand recycled concrete beam and a manufacturing method thereof, comprising prefabricated assembleable permanent formwork and FRP rib seawater sea sand recycled concrete beam; the prefabricated assembleable permanent The formwork is assembled from corner strip pieces, the first panel, the second panel and positioning connectors, and the formwork is made of engineering cement-based composite material ECC and fiber woven mesh; the FRP reinforced seawater sea sand recycled concrete beam includes pouring in The seawater and sea sand recycled concrete in the prefabricated permanent formwork and the FRP reinforcement skeleton fixed in the seawater and sea sand recycled concrete. The invention effectively reduces the cost of formwork engineering through the compounding of TRE formwork and FRP-reinforced seawater and sea-sand recycled concrete, improves the ductility of FRP-reinforced seawater-sea-sand recycled concrete beams, ensures the long-term durability of FRP rebars, and solves the problem of existing integrity at the same time The formwork takes up a lot of space and is not easy to transport.

Description

Technical field [0001] The present invention relates to an assembled permanent template to laminate the FRP ribs seafood seafood regenerative concrete beams and their production methods, which belong to engineering technology, such as sea industries, port structures and hydraulic structures. Background technique [0002] The Necessity of Raoli Sand Resources and Ecological Environmental Protection Plus Transportation Cost, Industrial Stop Restrictions, etc. How to use the necessity and importance of seawater seafood resources in marine engineering construction. At the same time, the regenerative aggregate is used as the preparation of the concrete, and the maximum use of resources can be achieved. [0003] Fiber Reinforced Polymer, referred to as FRP ribs have superior performance such as high strength, corrosion resistance, anti-fatigue, is an ideal alternative material for reinforcing reinforcements in an extremely erosive environment. Therefore, the FRP-rib sea-salad regenerat...
