The plate-fastening scaffold (also known as the disc scaffold or socket-and-spigot plate-fastening scaffold) is a modular, high-load-bearing modern scaffold system, with the following core structural features:
1. Node connection method: disc + pin
Disc design: A circular connecting disc with 8 holes (typically spaced at 500mm or 600mm) is welded onto the upright tube, facilitating quick insertion and connection of horizontal and diagonal tubes.
Pin locking: The wedge-shaped pins at the ends of the horizontal and diagonal rods are inserted into the holes in the circular disc, and secured through self-locking due to gravity or by tapping, ensuring rigid connection at the node and strong resistance to torsion.
2. Rod standardization and modularization
Upright tube: Made of Q355B high-strength steel pipe, commonly used specifications include Φ48.3mm, Φ60.3mm, etc. The length is designed according to modulus (such as 0.5m, 1m, 2m).
Horizontal bar and diagonal rod: They are connected through plugs and discs, forming a stable triangular truss structure that enhances overall stability.
3. High load-bearing capacity
The single pole can achieve a bearing capacity of 20-60kN (design load), making it suitable for heavy-load construction scenarios (such as bridges and high-rise buildings).
The rigid connection of nodes reduces the risk of loosening and is superior to the friction-fixing method of traditional coupler-type scaffolding.
4. Multi-functional component
Adjustable base/jacking: used to adjust the height and levelness of scaffolding, adapting to uneven foundations.
Accessories such as ladders and platform boards: Integrate safety access features to reduce the need for additional construction.
5. Safety and efficiency
Fall protection design: Some models are equipped with hooked pedals or guardrail sockets.
Quick assembly and disassembly: No need to tighten bolts. Workers can complete the assembly with a hammer, achieving an efficiency increase of over 3 times compared to the fastener type.
6. Materials and Surface Treatment
The steel pipe is treated with hot-dip galvanizing or epoxy coating process, making it corrosion-resistant and durable (with a lifespan of over 15 years).
Typical application scenarios: Fields requiring high stability and rapid construction, such as high-rise buildings, bridge engineering, and stage setup. Its structural advantages make it one of the mainstream choices to replace traditional scaffolding.
