Sinus Joint – AP International Joints

Cosine Joint

Cosine joints are designed to take care of differential wheel movement over the joints. Cosine joints are fitting in medium to heavy class in industrial floor joint segment. These joints are designed to take care of differential movement within concrete mass below the surface of the floor. Its unique system of load transfer and bonding within concrete is integrated for effective performance of abused movement on the floor. Easy installation is the key to better performance of the floor

• dowel size 180x140x10mm ±20mm parallel and ±30mm perpendicular

Cosine joint evenly moves tension which gives correct mutual horizontal and side-by-side movements. Another advantage of these joints is easy installation. You just need to put the strip in proper place and anchor it to the ground. Anchoring elements size and shape are designed to give the biggest surface to move the tenses between parts of the floor.

Conecto Cosine system allows for the free movement of forklifts which wheels are particularly damaging for wrong made expansion joints.
