How to weld on a concrete surface

When steel structures have to be connected to a concrete surface, the structural designer can use either a bolted connection or welding. We all know that you cannot perform welding on a concrete surface. Use of awelding plate (fastening plate) is common practice for this purpose. Sometimes fastening plates transform huge loads, and they are highly critical points of the structure. Even though this solution is widely used, designers and contractors continuously face certain challenges: How should we design the anchoring in concrete? What are the safe edge distances without the risk of breakage? Do we need some additional reinforcement? Where can we get reliable products? 

How does the Peikko solution work?

Peikko provides a wide range of tested and approved standard fastening plates, for different load sizes. The Peikko Designer® software makes safe and correct design easy. The structural designer can select the 3D view of the structure designed, indicate the location of the steel profile to be fixed, add forces affecting the joint, and just let Peikko Designer® do the work. It calculates the necessary plate, anchoring, and additional reinforcement. The structural designer can choose to use a standard fastening plate or design his or her own plate. When choosing Peikko fastening plates, the contractor can always rely on an efficient industrial production process, fast deliveries, and economical pricing.

Peikko’s standard SBKL, JPL, P2KL, and P3KL fastening plates have undergone rigorous testing and are ETA approved. Also Peikko customized fastening plates fulfill the strict quality requirements set for critical load‑bearing structures in structural joints.
