AI Technical Summary
Technical Problem
The existing precast steel bar connecting sleeves require repeated rotation when connecting the second steel bar, which increases the workload and reduces the installation efficiency.
Method used
It adopts a combination structure of end sleeve, slot, plug block, connecting plate, gear, toothed ring, swing rod and clamp plate. The clamp plate limits the position of the steel bar, so that a stable connection can be achieved without rotating the steel bar.
Benefits of technology
This achieves a stable connection between the reinforcing bar and the sleeve, reduces the intensity of the connection work, and improves installation efficiency.
