Door Frame

The door frame is the basic unit that constitutes the overall scaffolding structure. It takes the form of a "door" or "H" shape and is welded from horizontal rods, vertical rods or reinforcement rods. It is usually made of Q235 steel tubes to bear the perpendicular pressure from the plank and construction load with a common width of 1.2m or 1.9m and height of 1.7m or 1.9m. Two adjacent frames are connected by cross bracing to form the basic load-bearing structure.

Connection Method

Horizontal connection: Use cross bracing along the longitudinal direction to enhance the stability and anti-overturning ability of the door-frame in the horizontal direction; on the top of the frame, use grid or plank to connect each frame into an entire structure,forming a stable working platform.

Vertical connection: Use joint pin and locking arms to connect the upper and lower door frames together to ensure the coaxiality and stability of the vertical standard in the perpendicular direction, allowing the load to be smoothly transmitted.
