Prestress zinc-based double-coating steel structure net rack
The invention discloses a prestress zinc-based double-coating steel structure net rack. The net rack comprises a grid and prestress steel cables and is characterized in that the grid is formed by connecting multiple oblique equilateral polygons in a sealed mode, force conversion devices are arranged on stay cable sections of the grid, transmission devices are arranged on lower chord cross points in the middle of the grid, and after the prestress steel cables penetrate through the force conversion devices and the transmission devices, the two ends of the prestress steel cables are fixed to two supporting base points of the grid respectively; the surface of a metal base material of the grid is protected by adopting double coatings, the bottom layer of the double coatings is a zinc-based heavy-duty anticorrosion powder coating layer and is 50-110 micrometer thick, and the surface layer of the double coatings is a decorative or functional thermosetting powder coating layer and is 50-110 micrometer thick. The prestress zinc-based double-coating steel structure net rack has the advantages of being easy to construct, prominent in anticorrosion effect and low in manufacturing cost.
