Expansion joint formwork element with transverse force dorns for force transmission and rubber water bar

Transverse force dowels (dorn) enable movement in the direction of the slab plane. The opposite slab edges are positively connected. Due to the anchor body, highest loads can be transmitted, even in minimum component thicknesses.
The transverse force dowels (dorn) can be integrated into the construction joint elements at the factory, thus minimising the assembly time and demands on the workforce at the construction site.
The elements can be equipped with fixtures for interior expansion rubber water bars, which considerably facilitate installation of the sealing at the construction site.
