The Cosinus Slide® Design
The Cosinus Slide®armor joint has a unique technology that permits the load bearing capacity of the armor joint to be that of the complete concrete floor. The top section is made up of two 0.2 inch (5 mm) thick corrugated cold rolled steel profiles. Instead of traditional anchor studs, the joint is anchored into the concrete by a technologically advanced continuous rebar system which weaves itself along the total length of the joint. Preventing overflowing of concrete, an adjustable steel plate stands between the two halves of the joint.
