Ringlock scaffolding and wheel scaffolding are not the same type. Many people in China confuse ringlock scaffolding with wheel scaffolding, which is obviously wrong. The ringlock scaffolding technology originated in Germany and is the mainstream product in Europe and America. Our country has introduced ringlock scaffolding since the beginning of the 20th century.
Ringlock scaffolding is mainly divided into vertical rods, cross rods, and inclined rods. All kinds of rods are integrated with dedicated connection accessories. The connecting calipers on the horizontal rod and the inclined rod are fixed on the connecting plate of the vertical rod through a bolt. The connecting plate of the vertical pole has a total of 8 holes, 4 small holes are dedicated for cross bars, and 4 large holes are dedicated for diagonal bars, and they are evenly arranged.
1. Advanced technology
The disc type connection method is the international mainstream scaffolding connection method, and the reasonable node energy can achieve that the force transmission of each member passes through the node center. Ringlock scaffolding is mainly used in European and American countries and regions, and is an upgraded product of scaffolding. It has mature technology, strong connection, stable structure, safety and reliability.
2. Upgrading of raw materials
The main materials of ringlock scaffolding are all low-alloy structural steel, which is 1.5 times stronger than traditional scaffolding.
3. Hot-dip galvanizing process
The main parts of ringlock scaffolding adopt internal and external hot-dip galvanizing anti-corrosion process. It 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 entire product processing has to go through 20 procedures. Each process is carried out by professional machines, reducing the intervention of human factors. Especially for the production of horizontal and vertical poles, the self-developed automatic welding machine is used to achieve high product 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, and the breaking load reaches 19 tons, which is 2-3 times that of traditional products.
6. Less dosage and light weight
Under normal circumstances, the distance between the vertical poles is 1.5 meters and 1.8 meters, the step distance of the cross bars is 1.5 meters, the maximum distance can reach 3 meters, and the step distance can reach 2 meters. Therefore, the amount of the same support volume will be reduced by 1/2 compared with the traditional product, 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 more conveniently. Tie-up and disassembly fees, transportation fees, rental fees, and maintenance fees will be saved accordingly, and under normal circumstances, it can save 30%.
Ringlock scaffolding, as a new type of formwork support frame, is now more and more recognized by China Railway System and China State Construction System, as a scaffold with twice the price of a bowl buckle scaffolding. The following analyzes the four major advantages of ringlock scaffolding from the four aspects of its ringlock scaffolding functionality, safety, service life and space.
1. Complete functionality
Ringlock scaffolding adopts a uniform 500mm disc distance, with its vertical poles, diagonal poles and tripods, it can be built into bridge supports of different spans and different cross-sections, stage supports, lighting towers, etc. The traditional bridge formwork system is cumbersome and only suitable for specific specifications, which has great limitations. Ringlock scaffolding can be set up into template brackets with different shapes and functions to meet the construction needs of various styles.
2. Good safety
Ringlock scaffolding adopts self-locking connecting plate and pin. The pin can be locked by its own weight after being inserted, and its horizontal and vertical diagonal bars make each unit a fixed triangular lattice structure. The frame body will not deform after being subjected to horizontal and vertical forces. Ringlock scaffolding is a complete system, and both scaffolding boards and step ladders can play a role in ensuring the stability of the frame and the safety of workers. Therefore, compared with other laying scaffolding, the hook pedal of ringlock scaffolding improves the safety of the rack to a higher level.
3. Long service life
Ringlock scaffolding adopts uniform hot-dip galvanizing surface treatment, which completely eliminates paint and spray paint surface treatment. In addition to reducing the high per capita maintenance cost, this surface treatment method that does not fall off the paint and does not rust, it also enhances the image of the project. The galvanized surface treatment method extends the life of the steel pipe to 15-20 years.
4. Large space
In the traditional bridge support construction, the spacing of most bowl buckle scaffolding is below 1.2 meters, even reaching 0.6 meters and 0.9 meters. This resulted in the lack of space on the construction site. After the erection was completed, the workers were unable to enter the middle of the frame for inspection and acceptance, and it was even difficult to take out a thing if it dropped. The ringlock scaffolding pole adopts Q345b low-alloy structural steel, which improves the bearing capacity and allows the scaffolding step and spacing to be enlarged, thus expanding the construction space for workers and the acceptance space for supervision.
