High efficiency: The longest commonly used rod is 3130mm and weighs 17.07kg. The assembly and disassembly speed of the whole frame is 3 to 5 times faster than the conventional one. The assembly and disassembly is fast and labor-saving. Workers can complete all operations with a hammer, avoiding many inconveniences caused by bolt operation.

2: Large bearing capacity: The connection of the vertical pole is coaxial socket, and the cross bar is connected to the vertical pole by a bowl buckle joint. The joint has reliable bending, shear and torsion mechanical properties. Moreover, the axis lines of each bar intersect at one point, and the node is in the plane of the frame. Therefore, the structure is stable and reliable, and the bearing capacity is large. The bearing capacity of the whole frame is improved, which is about 15% higher than that of the coupler steel pipe scaffolding under the same situation.
3: Safe and reliable: When designing the joint, the spiral friction and self-gravity of the upper bowl buckle are taken into consideration, so that the joint has a reliable self-locking ability. The load acting on the crossbar is transmitted to the vertical pole through the lower bowl buckle, and the lower bowl buckle has a strong shear resistance (maximum 199kN). Even if the upper bowl buckle is not tightened, the crossbar joint will not fall out and cause an accident. At the same time, it is equipped with a safety net bracket, a crossbar, a scaffolding board, a footboard, and a ladder. The pole accessories such as the cantilever beam and the wall support are safe and reliable to use.
4: Easy to process: The main component is made of Φ48×3.5, Q235B welded steel pipe, the manufacturing process is simple, the cost is moderate, and the existing coupler scaffolding can be directly processed and modified. No complex processing equipment is required.
