An Introduction to Disc-Coupler Scaffolding: A Comprehensive Analysis of Its Technical Features

Disc-coupler scaffolding is a new type of scaffolding and an upgraded version of bowl-coupler scaffolding.

It is also known as chrysanthemum-disc scaffolding, plug-disc scaffolding, wheel-disc scaffolding, and coupler-disc scaffolding.

 

                                                            I. Basic Structure of the Socket:

 

A circular disc with a diameter of 133 mm and a thickness of 10 mm, with 8 holes drilled into it

 

 

Poles: Made of φ48×3.5 mm Q345B steel pipes, with a disc welded to the pipe at 0.50-meter intervals along the specified length; the bottom of the pole is fitted with a connecting sleeve.

 

 

Crossbar: Weld plugs with pins onto both ends of the steel pipe 

 

 

Diagonal Brace and Upright Assembly: Insert the diagonal brace pin into the diagonal hole in the upright, and tap it into place in the same manner.

 

                                                             

                                                                         II. Key Features of Disk-Coupler Scaffolding
1. Advanced Technology
The disk-coupler connection method is the internationally recognized standard for scaffolding connections.
The rational joint design ensures that the force transmitted by each member passes through the center of the joint, making it an upgraded version of traditional scaffolding.
 Mature technology
 Secure connections
 Structural stability
 Safe and reliable

 

2. Upgraded Raw Materials
All primary materials are made of low-alloy structural steel (GB Q345B), which is 1.5 to 2 times stronger than the ordinary carbon steel pipes (GB Q235) used in traditional scaffolding.

3. Hot-Dip Galvanizing Process
All major components undergo both internal and external hot-dip galvanizing for corrosion protection, extending the product's service life and further ensuring safety, while maintaining an attractive and aesthetically pleasing appearance.

4. Reliable Quality
Starting from material cutting, the entire manufacturing process involves more than 20 production steps, each carried out using specialized machinery to minimize human intervention.
In particular, the production of crossbars and upright poles utilizes proprietary fully automated welding machines, ensuring:

High product precision
Strong interchangeability
Stable and reliable quality

5. Low Material Usage and Lightweight
Vertical pole spacing: 1.5 m, 1.8 m; horizontal pole spacing: 1.5 m. Compared to traditional products: material usage is reduced by approximately 1/2, and weight is reduced by approximately 1/2 to 1/3.

6. Quick Assembly and Low Cost
Due to the disk-coupler scaffolding's high load-bearing capacity, reduced material usage, and light weight, workers can assemble it more easily-much like building with blocks-to erect the entire formwork system.
The main cost savings include rental fees and labor costs for erection.

 

                                                                       III. Design Highlights
The ingenious design of Entry Point C features a narrow top and a wider bottom. Due to the rivets at the bottom of the latch, the latch remains movable yet cannot slip out of the horizontal bar, making it less likely to be lost.
