Ringlock scaffolding used in large-scale construction includes 4-hole and 8-hole systems. Technical parameters and five steps to install this scaffolding system need to comply with international standards.
Ringlock scaffolding (Cobra) was invented, far away from traditional scaffolding systems, and becoming a bright “candidate” in today’s construction market. This disc scaffolding system continuously develops, providing a flexible approach to many structures, including circular tower architectures in complex terrain. So why does the Ringlock rig have outstanding safety, stability, and good bearing capacity? Let’s learn more about the Ringlock system through the below article.
About Ringlock scaffolding (Cobra): Classification, structure, and basic installation process
Ringlock Scaffolding is one of the complete omnidirectional modular scaffolding systems on the market. It is widely used in construction and industrial projects because of its outstanding durability, safety, and flexibility. However, this first-class safety truss system comprises very simple components and is easy to disassemble. Specific specifications and installation processes for the Ringlock truss are presented below.
What is Ringlock scaffolding (Cobra)? Outstanding features of disc scaffolding system
Ringlock scaffolding is also known as rosette scaffolding, disc scaffolding, Layher scaffolding. This is the most popular scaffolding system today, used in high-rise and large-scale construction projects with high requirements for safety and solidity. Compared with traditional scaffolding, Ringlock Scaffolding (Cobra) has a big load capacity, high stability, no vibration, creating high security during use. The key to these advantages lies in the connections in the structure of the scaffolding.
Ringlock is designed to be flexible, capable of being applied to many different construction scaffolding solutions. Typically such as hanging scaffolding, birdcage scaffolding, putlog scaffolding, stair scaffolding, formwork scaffolding. Besides, Ringlock comprises fewer key components. Disassembling and setting up the scaffolding structure is also relatively easy and fast, significantly reducing costs, human resources, and implementation time.
Classification of Ringlock scaffolding (Cobra) is commonly used on the market today
Currently, there are two types of Ringlock scaffolding (Cobra) on the market that are commonly used in construction. That is:
- Ringlock system with four holes: There are four holes on the rosette of the scaffolding, and four braces can be connected.
- Ringlock system with eight holes: There are eight holes on the rosette of the scaffolding, and eight braces can be connected
Standard Ringlock Scaffolding Structure and Specifications
Ringlock scaffolding (Cobra) is usually manufactured by high-quality steel material Q235 or Q345 with main components including horizontal and vertical braces of different sizes. These pipes are manufactured according to international standards with a diameter of 48.3×3.25mm. Three other connecting elements of the scaffolding are horizontal brace, cross brace, and latch. The rosette discs on the vertical post are arranged with a standard spacing of 50cm or 1m.
Specifications of Ringlock:
- Vertical has size 500mm -1000mm – 1500mm – 2000mm – 2500mm – 3000mm, thickness 2-2.3mm. Rosette is attached to the tubes with a spacing of 0.5 m with thickness of 8-10mm
- Ringlock Ledger is available in lengths of 0.39 m, 0.73 m, 1.04 m, 1.09 m, 1.40 m, 1.57 m, 2.07 m, 2.57 m, and 3.07 m
- Diagonal Braces: Available in all Ledger lengths and lifting heights from 1.0 m – 2.0 m.
- Base Jack: It is height-adjustable to compensate on uneven surfaces, ensuring the scaffolding stays flat when working.
In addition, the scaffolding system also has other components that support creating a multi-purpose structure such as a Staircase, Side Bracket, U head jack, Steel Planks, Base Jacks, and Base Collars.
How to install Ringlock Scaffolding (Cobra): A simple and straightforward 5-step process
As mentioned above, the scaffolding system is the most solid and safe, but the Ringlock scaffolding (Cobra) has a straightforward structure and is easy to install. The installation procedure is done as follows:
Step 1: Ground treatment of Ringlock truss installation area
Step 2: Locate and arrange scaffolding base jack according to the original diagram, adjust the appropriate height on the floor surface
Step 3: Install the vertical rod to the base jack, fasten them with the corresponding horizontal bar and disc fasteners.
Step 4: Install the horizontal brace, cross brace. Use a hammer to drive the bolts of the crossbar and horizontal brace.
Step 5: Finally, install the U head jack and adjust the height appropriately
The work of installing the Ringlock system is relatively quick and simple, requiring only a hammer and not requiring much labor. However, the performer needs to have the technique and strictly follow the standards to ensure the quality and safety of the whole structure. In addition, installers should note that the links in the overall system always provide flexibility and convenience but must be safe and secure.
In addition to saving costs and workers, the Ringlock scaffolding system also brings many benefits such as safety, high strength, and extreme flexibility in an erection. Modern large-scale constructions require a safer and more versatile scaffolding solution to support overhead operations efficiently. As a result, Ringlock becomes the perfect choice in construction projects with many different models of scaffolding.
