In the field of rapid construction of bridges and building projects, on-site connection of rods is very common and used in large quantities. During on-site construction, rapid connection of rods is widely used in the rapid construction of bridges and building projects, and the quality, life and safety of rod connections are becoming more and more important.

[0003] The commonly used rod connection methods now are: first, the press-fit connection of a semi-conical connector + a cone sleeve; its characteristics are fast connection, easy operation, and high connection strength. The disadvantage is that it is a rigid connection with the rod, has poor fatigue impact resistance, low fatigue life, and requires equipment loading and manual operation at the same time, which is not suitable for high-rise operations. Second, the ends of the rods need to be processed with threads and connected with connecting screw sleeves; its characteristics are simple operation, certain connection strength, and can be used in high-rise operations, but its disadvantages are too obvious, low connection strength, poor fatigue impact resistance, and low fatigue life. It is necessary to make threads on the rods in advance, and the production cost is very high. The third is the general rod connection construction method at the wet joints of prefabricated components, which adopts rod bending and lap connection or rod welding connection. It has high strength, requires more materials and labor, and is difficult to construct. It is not suitable for on-site connection operations of high-rise building structure rods.
