The support frame is divided into vertical rods, horizontal rods, and oblique rods. There are eight holes on the disc, four small holes are dedicated to the horizontal rods; four large holes are dedicated to the oblique rods. The connection methods of the horizontal bar and the oblique bar are all bolt-type, which can ensure the firm connection between the bar and the vertical bar. The joints of the horizontal bar and the inclined bar are specially manufactured according to the arc of the pipe, and they are in full contact with the steel pipe of the vertical bar. After the bolt is tightened, three points of force (two points above and below the joint and one point of the bolt against the disc) can be firmly fixed and increased. The structure is strong and transmits horizontal force. The cross bar head and the steel pipe body are fixed by full welding, and the force transmission is correct. The slanting rod head is a rotatable joint, and the slanting rod head and the steel pipe body are fixed with rivets. As for the connection method of the pole, the square tube connecting rod is the main method, and the connecting rod has been fixed on the pole, and there is no need for additional joint components to assemble, which can save the trouble of material loss and arrangement.
Buckle node:
Through the disc welded to the vertical bar, the horizontal bar and the inclined bar are snapped into the disc by rod-end buckle joints and connected with wedge-shaped bolts. There are eight holes on the disc, four small holes are dedicated for horizontal rods; four large holes are dedicated for oblique rods.
Buckle scaffolding is mainly divided into two types: type A and type B. Type A: 60 series, the diameter of the pole is 60mm, mainly used for heavy support, such as in bridge engineering. Type B: the 48 series, the diameter of the pole is 48mm, mainly used in the fields of house construction and decoration.

Main feature:
1. The disc-type connection method with advanced technology is the international mainstream scaffold connection method. The reasonable node design can achieve the force transmission of each rod through the node center. It is mainly used in European and American countries and regions. It is an upgraded product of scaffolding. Mature technology, firm connection, stable structure, safe and reliable.
2. Raw material upgrade
The main materials are all made of low-alloy structural steel (national standard Q345B), whose strength is 1.5-2 times higher than that of ordinary carbon steel pipes (national standard Q235) of traditional scaffolding.
3. Hot-dip galvanizing process
The main components are all made of internal and external hot-dip galvanized anti-corrosion technology, which not only improves the service life of the product, but also provides a further guarantee for safety, and at the same time it is beautiful and beautiful.
4. Reliable quality
The product starts from blanking, and the whole product processing has to go through 20 processes, each process is carried out by professional machines to reduce the intervention of human factors, especially the production of horizontal bars and vertical bars, using a self-developed fully automatic welding machine, Achieve high product precision, strong interchangeability, stable and reliable quality.
5. Large bearing capacity
Taking the 60 series heavy-duty support frame as an example, the allowable bearing capacity of a single vertical pole with a height of 5 meters is 9.5 tons (safety factor is 2), and the failure load reaches 19 tons, which is 2-3 times that of traditional products.
6. Less consumption and light weight
Under normal circumstances, the spacing of the vertical poles is 1.5 meters and 1.8 meters, and the step distance of the horizontal bars is 1.5 meters. The maximum spacing can reach 3 meters, and the step distance can reach 2 meters. Therefore, under the same support volume, the dosage will be reduced by 1/2 compared with traditional products, and the weight will be reduced by 1/2~1/3.
7. Fast assembly, convenient use and cost saving
Due to the small amount and light weight, the operator can assemble it more conveniently. Building and dismantling fees, transportation fees, leasing fees, and maintenance fees will all be saved accordingly, generally 30% can be saved.
