[0002] In engineering projects such as buildings, ships, and ports, concrete structures and steel structures are usually used. However, when conventional concrete structures or steel structures are used in some harsh erosion environments (such as cold regions, oceans, and offshore areas, etc.), due to their low corrosion resistance or crack resistance performance, problems such as functional degradation and short service life are likely to occur. In addition, the concrete structures or steel structures used in these engineering projects are usually large-volume precast components, which generally have the problems of heavy weight, difficult transportation, and hoisting. The above two problems restrict the application scope of such structures to some extent. Summary of the Invention

Combining with the characteristics of good integrity and high plasticity of traditional concrete structures or steel structures, it can solve the difficulties in the current civil engineering industry.

This system can be adjusted into different structural forms of different shapes with basic wall panels as units according to the size and style of the structure body. The surface layer of this composite system has the advantage of corrosion resistance, while the frame structure skeleton has high overall strength and good stability.
