Problems solved by technology

[0003] 1. The locking of the tube fasteners of the tube buckle scaffolding is carried by frictional force, which is easy to fall off and cause safety accidents. It has been eliminated in developed countries;

[0004] 2. The bearing capacity of portal scaffolding is small, and the overlapping height is limited; the bowl-buckle scaffolding is supported by short-distance horizontal bars at right angles and uses a large amount of steel, so the lateral bearing capacity is poor and it is easy to collapse in a large area;

[0005] 3. Due to the wedge-shaped flat pin, the self-locking failure of the wedge-shaped flat pin under the action of factors such as horizontal load, dynamic load, thermal expansion and contraction, etc., will cause the node to loosen, and the fra...
