Abstract
This invention relates to a device for spanning expansion gaps in bridge decks or roadways. The invention provides a small, simple and low cost edge channel member of U-shape which may be welded to one type or a variety of different commericially available steel sections in accordance with any particular needs. Screws accessible from above are provided to retain the edge portions of an elongate body of flexible resilient elastomeric material which spans the expansion gap. Thus, the invention permits the installation of expansion joints for any desired thickness of the wearing course and any type of fastening to the concrete base course.
