For decades, KÖCO shear connectors have been used to anchor steel components in solid construction. They transfer forces and torques in any direction from the steel part into the concrete. The positive connection of the shear connector secures the transmission also in the tension zone of the concrete. Very fast welding of the shear connector with the proven KÖCO stud welding systems is an important factor for safety and efficiency of the connection.
Steel components with welded-on KÖCO shear connectors are subject to building regulations in terms of manufacture and assembly in European Technical Assessments (ETA-03/0039 for structural steel and for stainless steel). The basis for this is European Assessment Document 330084-00-0601 "Steel plate with cast-in anchors".
The design is carried out in accordance with CEN / TS 1992-4: 2009 "Design of fastenings for use in concrete". The change to the 2019 publicized standard EN 1992-4 is planed. For dimensioning we offer the program "StudCalc Pro"; it designs steel components with welded-on KÖCO shear connectors according to the current standards.
