AI Technical Summary
Traditional ultra-long and large-area concrete structure floor anti-cracking construction devices are prone to produce gaps during the installation of anti-cracking bars or anti-cracking steel mesh, causing cracks in the concrete structure floor and affecting the stable use of the device.
The combined design of fixed cylinder, docking rod, sliding frame, sliding cylinder, magnet ring and air bag is adopted. The sliding and rotation of the docking rod are achieved through the interaction of threaded rod, magnet ring and gas supply of air bag. The installation is stabilized by the limit of sliding tip and the repulsive force of magnet ring, which alleviates the cracks caused by temperature shrinkage of concrete.
It effectively alleviates the temperature shrinkage cracks of ultra-long and large-area concrete structure floors, ensures the stability and crack resistance of the device, and avoids the formation of gaps.
