ABSTRACT:
An expansion joint cover for sealing off a space between first and second structural bodies is provided, and includes, first and second side members, and bridging and elastomeric sealing means, the latter means comprising, bridging plate means resting slidably upon an inner ledge wall portion of the first side member and further resting against the second side member so as to form a bottom wall of a cavity bordered by the first and second side members. The bridging plate means is covered by bond-inhibitor means in the cavity and is provided with anchor means projecting into the cavity. An elastomeric sealing member embedding the anchor means and substantially filling the cavity is characterized by being formed and cured in the cavity and thereby being bonded to the first and second side members and inhibited against bonding to the bridging plate means by the bond-inhibitor means.
