The disc-type scaffolding is also called disc-type scaffolding. The disc-type scaffolding technology originated in Germany and is a mainstream product in Europe and the Americas. The support frame is divided into vertical rods, horizontal rods, and diagonal rods. The disc has eight holes, four One small hole is dedicated to the horizontal bar; four large holes are dedicated to the diagonal bar. The connection method of the cross bar and the diagonal bar is a bolt type, which can ensure that the bar and the vertical bar are firmly connected. The joints of the cross bar and the diagonal bar are specially made according to the arc of the tube, and they are in full contact with the vertical steel tube. After the bolt is tightened, it is stressed at three points (the upper and lower two points of the joint and the pin to the disc) can be firmly fixed and increased. The structural strength and horizontal force are transmitted. The crossbar head and the steel pipe body are fixed by full welding, and the power transmission is correct. The inclined rod head is a rotatable joint, and the inclined rod head and the steel pipe body are fixed by rivets. As for the connection method of the vertical pole, a square tube connecting rod is mainly used, and the connecting rod is fixed on the vertical pole, and no other joint component is used for combination, which can save the trouble of missing materials and finishing.
1. Advantages of plate buckle scaffolding:
1. Perfect technology
The disc-type connection method is the international mainstream scaffolding connection method. The reasonable node design can achieve the power transmission of each member through the node center. It is mainly used in European and American countries and regions. Firm, stable structure, safe and reliable.
2. Raw material upgrade
The main materials are all made of low alloy structural steel (national standard Q345B), which is 1.5-2 times stronger than ordinary carbon steel tubes (national standard Q235) of traditional scaffolding.
3. Hot galvanizing process
The main components are 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 makes it beautiful and beautiful.
4. Reliable quality
The product starts from cutting, the entire product processing has to go through 20 processes, and each process uses a special machine to reduce the intervention of human factors, especially the production of crossbars and uprights. The product has high precision, strong interchangeability, and stable and reliable quality.
5. Large bearing capacity
Take the 60 series heavy-duty support frame as an example, the allowable bearing capacity of a single pole with a height of 5 meters is 9.5 tons (safety factor is 2). The destruction load reached 19 tons. It is 2-3 times that of traditional products.
6. Low dosage and light weight
Under normal circumstances, the spacing of the poles is 1.5 meters, 1.8 meters, the step of the crossbar is 1.5 meters, the large spacing can reach 3 meters, and the step distance reaches 2 meters. Therefore, the dosage under the same support volume will be reduced by 1/2 compared with traditional products, and the weight will be reduced by 1/21/3.
7. Fast assembly, easy to use and cost saving
Due to the small amount and light weight, the operator can assemble more conveniently. The disassembly, transportation, rental, and maintenance costs will be saved accordingly.
