This production method has the advantages of high efficiency, energy conservation, environmental protection, and controllable quality, and is widely used in modern construction projects. The extended parts at both ends of the prestressed steel bars in commercial concrete precast components need to be cut off. In order to prevent the steel bar heads from splashing when breaking, causing safety accidents, a clamping device is usually required to clamp and fix the steel bar ends.

[0003] As disclosed in a steel bar clamping device for commercial concrete precast component production with the authorization announcement number CN214925584U, it includes a bottom plate and a top plate. The bottom plate and the top plate are arranged at intervals to form a clamping space for the corresponding steel bars to pass through between the bottom plate and the top plate. A clamping connecting piece is also arranged on the bottom plate and the top plate to relatively clamp the bottom plate and the top plate to clamp and fix the steel bars located in the clamping space. After adopting the above technical solution, the beneficial effects of the utility model are: it can be reused for a long time and is convenient to disassemble, is not easy to be damaged after long-term use, the overall use cost is very low, and no construction waste will be generated.

[0004] Although the above patent can be reused for a long time and is convenient to disassemble, when clamping the steel bar ends with the top plate and the bottom plate, it is necessary to use tools to tighten and fix the bolts at each position, which is more cumbersome in operation and has a high labor intensity.
