Abstract: To avoid leakage in concrete structures with dilatation joints and to prevent dirt from accumulating in the joints there has been developed a dilatation joint element which is easy to mount, reliable and essentially maintenance-free. The dilatation joint element according to the invention is comprised of opposed, longitudinal angle elements interconnected in pairs and made of metal with interposed jointing compound, reinforcement bands and robber elements. With curved band sections and rubber elements between the angle elements and a curved jointing compound section which is attached to the upper band section there is provided a supporting, power-compensating and power-distributing function when the joint is subjected to load, both at compression, expansion and shearing, providing a tight, reliable and loadable joint with good fatigue strength.
