<p>An expansion joint with an elastomer seal having longitudinal frames made from aluminum extrusions extending longitudinally of an expansion joint for pavements and bridge decks. The longitudinal frames are mounted by anchor bolts in the pavement or bridge deck concrete, which pavement or bridge deck has a concrete or asphaltic wear surface. The elastomer seal is fixedly held in the longitudinal frames by elongated tongue and groove means, and the joint space is spanned by at least one shallow, V-shaped elastomer wall which deforms downwardly as the joint width becomes narrower. The longitudinal frames are held in position in steps in the concrete adjacent to the joint by the anchor bolts, which have threaded ends projecting upwardly into an upwardly facing longitudinal channel and the hollow space of a hollow segment of substantially square cross section in the respective longitudinal frames. Access to the threaded ends of the anchor bolts in the hollow segment is gained through openings having removable covers, which openings are provided in the top wall of the hollow segment.</p> |
