With its unique design and performance, the socket-type disc-lock scaffolding has become the optimal solution for solving the challenges of construction in high-rise, large-span, and complex terrain. In the export construction industry, high-rise, large-span, and complex terrain construction has become the norm, and traditional steel pipe scaffolding can no longer meet the requirements in terms of safety, efficiency, and adaptability. The socket-type disc-lock scaffolding, with its unique design and performance, has become the optimal solution for solving these problems.
First, the structure of disc-lock scaffolding is suitable for high-rise structure construction.
With a 200kN load-bearing capacity, it provides a solid safety barrier at high altitudes. The intake towers and sluice gates of overseas hydropower stations are generally over 50 meters high. Under the dual challenges of lateral pressure and strong winds at high altitudes during concrete pouring, traditional scaffolding joints loosen, resulting in noticeable swaying and posing safety hazards. The disc-lock scaffolding utilizes disc-joint locking technology, achieving an axial load-bearing capacity of 200kN (equivalent to 20 tons) for the uprights and a tensile strength of 15kN for the joints. During the construction of the No. 3 intake tower at an international hydropower station, the 70-meter-high pouring platform remained completely stationary throughout the process. Safety inspections showed that the load-bearing capacity far exceeded design requirements, resulting in a 60% safety redundancy improvement compared to traditional scaffolding. This advantage stems from its unique joint design, which uses a locking mechanism to achieve a tight connection between the uprights and horizontal members, effectively distributing the load and improving overall stability.
Second, disc-lock scaffolding is suitable for large-span spaces.
A 6-meter horizontal member span frees up space for heavy machinery operations. The main powerhouse spans of overseas hydropower stations are often 20-30 meters, requiring large spaces to accommodate heavy equipment such as generator sets and hoists. Traditional scaffolding has an upright spacing of 1.5-2 meters, with dense uprights obstructing machinery passage and reducing material transportation efficiency. Disc-lock scaffolding can achieve a 6-meter horizontal span without the need for additional uprights. During the construction of the main powerhouse of an international hydropower station, the upright spacing was 3.5 meters, allowing a 50-ton crawler crane to pass directly through, increasing equipment installation efficiency by 40% and shortening the construction period from 25 days to 17 days. This advantage stems from its modular design, which increases the length of horizontal bars while reducing the number of uprights, achieving efficient utilization of large-span spaces.
Third, disc-lock scaffolding is suitable for complex terrain.
A 50cm adjustable base allows for precise leveling of sloping foundations. Overseas hydropower stations are often located in canyons and riverbanks, where sloping foundations and stepped terrain are common. Traditional scaffolding uses bricks and gravel for leveling, which can easily lead to uneven stress and tilting of the scaffold. The high-precision adjustable base (adjustment range 0-50cm) of disc-lock scaffolding ensures precise leveling. During the construction of a hydroelectric power station in a canyon, facing a 30° sloping foundation, the construction team completed the erection of a 500㎡ scaffolding structure in two days, controlling the horizontal error within 3mm. This saved three days of construction time compared to traditional scaffolding that required repeated leveling and adjustments, and the entire process was safe. This advantage stems from its adjustable base design, which allows for precise leveling of the scaffolding by adjusting the base height, adapting to complex terrain.
With its three core advantages—high load-bearing capacity, large span, and strong adaptability to complex terrain—disc-lock scaffolding is becoming a new favorite in the export construction industry. Choose it for more efficient and safer overseas project construction!
