22×150 Stud Welded Shear Connector: Long Connection Element for Maximum Depth and Strength
The 22×150 stud welded shear connector is a heavy-duty connection element designed to provide high tensile and shear strength in thick concrete systems. It is an ideal solution for bridges, viaducts, silos, and industrial structures.
Diameter: 22 mm
Length: 150 mm
Material: Low-carbon, high-strength steel
Application Method: Automatic stud welding machine
Ceramic Compatibility: Welded with ceramic ferrule
Standards: EN ISO 13918 – ISO 14555
Advantages
Maximum anchorage depth: The 150 mm length provides full embedment and strong anchorage within concrete.
High performance under heavy loads: The combination of large diameter and extended length creates a strong connection between steel and concrete.
Seismic resistance: Provides high structural rigidity in earthquake-prone areas.
Long-lasting connection: Maintains structural integrity even under demanding conditions.
Fast installation: Saves time on construction sites with automatic welding systems.
Applications
- Thick concrete floor slabs
- Bridge and viaduct decks
- Heavy-duty industrial foundations
- Silo, tank, and crane bases
- Seismic strengthening projects
- High-strength steel structural systems
Application Information
The 22×150 stud welded shear connector is installed perpendicular to the steel surface using automatic stud welding machines. During the high-current welding process, the end of the stud melts and bonds securely to the steel surface. The ceramic ferrule protects the welding area and improves weld quality. After welding, the surface is cleaned and prepared for concrete pouring.
