AI Technical Summary
Existing expansion anchors cannot meet quality standards due to displacement under external forces and repeated crack opening and closing in cracked concrete, and the lack of specialized installation tools leads to unstable performance.
An anti-seismic expansion anchor and its installation tool were designed. The anchor uses a cone head with a fastest curve structure and a serrated expansion plate. Combined with the hammering and rotation mechanism of the installation tool, the expansion plate is cut into the concrete and fits tightly in real time through continuous hammering and torque application. The hammering force and torque are controlled by a spring to coordinate the expansion and installation of the expansion plate.
It achieves stable fixation of expansion anchors in concrete, meets the tensile performance of national standards, and improves the stability and reliability of installation effect through the coordination of installation tools.
