AI Technical Summary
In existing technologies, bolts for precast reinforced concrete foundations cannot be integrated with the foundation blocks, leading to bolt loss and affecting installation progress and results.
The first splicing block is fixedly connected to the left side of the base block. A circular groove is opened on the front side of the first splicing block to connect the threaded bolt. The upper and lower sides of the annular groove at the rear end of the bolt are fixedly connected to the second connecting rod. The outer wall of the second connecting rod is slidably connected to a spring and a trapezoidal locking block. The sliding column is slidably connected to the front side of the base block. The second splicing block is fixedly connected to the right side. Combined with the sliding mechanism and the protective shell, flexible splicing is achieved.
This design ensures that bolts are less likely to be lost during the splicing process, improving installation efficiency and the stability of the results, and enhancing the flexibility and adaptability of the splicing.
