ABSTRACT:
Two concrete slabs separated by a gap are interconnected by a molded expansion joint formed by a pair of composite marginal bodies formed of metal and elastomeric material which are disposed on opposite sides of the gap. Each marginal body includes a groove with an aperture which is open in the direction of the gap. An elastomeric sealing means is disposed to span the gap and be received through the marginal body apertures for mounting in the grooves thereof wherein each marginal body includes a metal mounting plate embedded in the elastomeric material thereof which overlies the groove associated therewith. Anchor means secure each of the marginal bodies against the slabs whereby the mounting plates therein reinforceably urge the longitudinal edges of the sealing means into a firm engagement against the slabs.
