Advantages
Maximum anchorage capacity: The 250 mm length provides a large contact area within thick concrete sections.
Superior tensile and shear strength: Delivers secure performance in structures subjected to extreme loads.
Resistance to seismic and heavy industrial conditions: Enhances structural rigidity and stability.
Structural integrity and long service life: Suitable for use in critical infrastructure projects.
Fast and reliable installation: Enables efficient application using automatic stud welding equipment.
Applications
- Extra-thick concrete slab systems
- Hydroelectric power plants
- Dam, bridge, and tunnel infrastructure
- Heavy machinery foundations
- Structures located in high seismic-risk zones
- Steel-to-concrete connections requiring deep anchorage
Application Information
The 22×250 stud welded shear connector is welded perpendicular to the steel surface using an automatic stud welding machine and a ceramic ferrule. After welding, the ferrule is removed and the weld area is cleaned. Its extended length increases the contact area within the concrete, resulting in enhanced strength, improved load transfer, and long-term structural performance.
Frequently Asked Questions (FAQ)
1. In which projects is the 22×250 stud welded shear connector used?
It is commonly used in dams, bridges, power plants, and heavy industrial infrastructure projects where thick concrete sections and high load-bearing capacity are required.
2. Is this length excessive?
No. It is specifically designed for very thick concrete slabs and applications that demand maximum structural safety and strength.
3. How is it installed?
It is installed perpendicular to the steel surface using a suitable ceramic ferrule and an automatic stud welding machine.
4. How deeply is it embedded into the concrete?
The stud is embedded along its full length, providing maximum bonding performance and efficient load transfer within the concrete structure.
