The disclosure relates to a joint-edge element for expansion joints in roadways wherein the anchoring parts, that extend in the longitudinal direction of the joint, just as the remaining parts of the joint-edge profiled element, are joined in one piece to the joint-edge element. At least one profiled part of the joint-edge element is produced by dividing the double profiled element in two profiled halves. Joint-edge elements having the double length of the particular extrusion casting or rolled element are produced through a single operation of extrusion or rolling. A particularly expedient embodiment is produced in such a manner that the anchoring parts are formed by parting a connecting portion of the double profiled element. The parting operation can be performed without considering the precision of manufacture, with relatively low expenditure. A secure holding and a perfect embedding in the concrete under-structure can be obtained in such a manner that the anchoring parts are produced through the parting operation effected along a line extending in the longitudinal direction of the joint and effecting a serration-type reciprocal meshing of the two halves of the connecting part. The line can here be undulated, dented or provided with another regular or irregular curvature. The serration type gaps permit one to obtain a perfect concrete work, since no cavities have to be filled.

Joint edge body for expansion joints in roads

The present expansion gap sealing device has a plurality of strips and elastomeric bodies between adjacent strips which extend longitudinally through the gap. The strips are supported by legs extending downwardly into the gap. Upper ends of the legs are connected to the strips. Lower ends of the strips are interconnected with each other in pairs whereby adjacent legs form a pair and an elastically yielding structure. The lower leg ends may be interconnected by bars and the entire supporting structure may be guided by movably supported guide means in the gap.
