360-Degree lockrand structure of roofing corrugated board

The invention relates to a 360-degree lockrand structure of a roofing corrugated board. The 360-degree lockrand structure comprises a base plate (1), a primary fastener (2) and a secondary fastener (3); the primary fastener (2) and the secondary fastener (3) are arranged on the two sides of the base plate (1); the primary fastener (2) comprises a vertical part (4) of the primary fastener, a second bent part (5) of the primary fastener and a first bent part (6) of the primary fastener, wherein the lower end of the vertical part (4) of the primary fastener is connected with the base plate (1), while the upper end of the vertical part (4) of the primary fastener is connected with one end of the second bent part (5) of the primary fastener, and the vertically downward first bent part (6) of the primary fastener is arranged on the other end of the second bent part (5) of the primary fastener; the secondary fastener (3) comprises a vertical part (7) of the secondary fastener and a bent part (8) of the secondary primary, wherein the lower end of the vertical part (7) of the secondary fastener is connected with the other end of the base plate (1), while the upper end of the vertical part (7) of the secondary fastener is connected with the bent part (8) of the secondary primary. The 360-degree lockrand structure of the roofing corrugated board has the advantages of simple and novel structure, quick installation, labor saving and time saving, simple lockrand operation, and good waterproof and sealing properties.
