Patent attributes
Concrete casting elements for forming an expansion joint in concrete including: a pair of expansion joint members each having a gasket mounting formation to which a gasket may be mounted in operative interposition between the expansion joint members for sealing the joint; a flange extending from a remaining portion along one side of the expansion joint member and retainer mounting means formed onto or into said remaining portion for mounting one or more retainer elements to protrude from the opposite side of the expansion joint member from the flange; the flanges of each one of the expansion joint members being formed to engage one with the other; the flange of one joint member at least partly overlying the flange of the other to provide an expansion joint upper face and such that the remaining portions may be spaced from one another when the flanges are so engaged; the flange of the other expansion joint including a lip formed to be substantially coplanar with the expansion joint upper face; and the flanges also being formed and positioned for protection of the gasket against damage.
