In our search for the perfect expansion joint, we introduce a complete new jointing solution which is realising the best load transfer system ever. The Cosinus Slide® joint solution with unique technology of load-bearing capacity of the floor without any dowel system.
The Cosinus Slide® joint is characterised by a stable double 2x5 mm Sinus steel plate on top opposed by a double Sinus steel plate on bottom. Instead of traditional anchor studs, the joint is fixed in the concrete by a special wreathed continuous rebar system over the total length of the joint and with connections top and bottom. A small steel plate in the middle prevents the overflowing of the concrete.
Thanks to the Sinus-Cosinus geometrical shaped form of the joint and the concrete, load transfer is not realised by the joint (with dowels) but by the floor itself. That’s why we say the joint is the floor, the floor is the joint. Each sinus corrugation on top is opposed by a Cosinus corrugation underneath. These crossed sinus corrugated steel plates shape small vertical steel-concrete columns over each other. The load-bearing of these columns defines the load-bearing capacity of the complete floor. The loads are transferred simultaneously and proportionally throughout and over the floor by those vertical Concrete Columns shaped and supported by the Sinus-Cosinus geometry. This unique load-bearing capacity of the floor slab is calculated and proved for all kinds of forklift
