Double fastener for fixing under the beam of a disc fastener rack
By using double fasteners under the beams of the disc-lock frame, the problem of eccentric force on the uprights was solved, and the load on the uprights was arranged axially symmetrically, thus improving the load-bearing capacity and installation stability.

AI Technical Summary
The traditional disc-lock scaffolding system's pole fastener configuration causes the uprights to be subjected to eccentric forces, affecting their load-bearing capacity.
A double fastener for the beam under the disc-lock frame is adopted, including a base frame, first and second pipe clamps, and first and second half clamps are connected by locking screws to ensure that the horizontal bar clamps are symmetrically arranged on both sides of the upright clamp to prevent eccentric force.
This design ensures that the load on the upright is located at the axial position, avoiding eccentric loads and improving the load-bearing capacity and installation stability of the upright.
