These parts are interconnected and mutually restricted to form an organic whole. According to different functions and uses, steel structures can be divided into many types, such as main beams, columns, roof trusses, bridges, steel plates, steel pipes, steel sheet piles and steel grids.

[0003] Most existing steel structures are fixed by bolts during assembly and connection, and the bolts only fix the connection parts, which results in a single reinforcement method.

Through the set connecting nails, the first screw hole and the second screw hole can be connected, and the first steel structure and the second steel structure can be reinforced.

[0005] In response to the above problems, although the existing patent can reinforce the first steel structure and the second steel structure by installing connecting nails in the first screw holes and the second screw holes, fixing only by connecting nails cannot achieve the effect of multi-point fixing, thereby affecting the stability of the connection. Summary of the invention
