COMPOSITE WRAPPED STEEL BAR AND MANUFACTURING METHOD THEREFOR, ON-SITE BENDING METHOD, AND APPLICATION

WIPO Patent Application WO/2024/088361

A1

The present application provides a composite wrapped steel bar and a manufacturing method therefor, an on-site bending method, and an application. The composite wrapped steel bar comprises a steel bar of a core portion and a composite protection layer wrapped around the surface of the steel bar. The composite wrapped steel bar of the present application has the characteristics of corrosion resistance, impact resistance, peeling resistance, good bonding performance with concrete, and a price–performance ratio, etc. A concrete structure is enhanced by using the composite wrapped steel bar provided by the present application, so that the durability of the structure can be significantly improved, and the service life of the structure can be prolonged. The composite wrapped steel bar provided by the present application is suitable for infrastructure construction in corrosive environments, for concrete structures obtained by directly mixing sea water and sea sand, and for the construction of offshore islands and reefs having national defense and economic value.
