Disc-locked steel tubular scaffolding is a new type of socket-type steel tubular scaffolding based on a disc-node connection system, which is composed of vertical poles, horizontal poles, diagonal poles and special accessories (such as adjustable bases, adjustable U-heads, foot planks, etc.). The vertical poles are welded with disc nodes, and the ends of horizontal poles and diagonal poles are equipped with wedge-shaped pins, which are quickly locked with the discs to form a stable three-dimensional stress structure.

The disc nodes and wedge-shaped pins form a rigid connection. Vertical poles, horizontal poles and diagonal poles bear forces collaboratively, with strong overall anti-overturning and anti-deformation capacity. The node pull-out resistance is ≥12kN, which can resist complex construction loads

No bolts or couplers are needed, and it can be locked with one click via pins. The installation and disassembly speed is 3-5 times that of traditional coupler-type scaffolding; workers can take up their posts after simple training, greatly shortening the construction period

Q355B steel has high strength and good toughness. The hot-dip galvanized layer thickness is ≥85μm, with excellent resistance to moisture, acid and alkali corrosion. The service life of the main structure can reach 15-20 years, and the turnover times are ≥200
