ABSTRACT:
A generally hollow compression type elastomeric seal with integral metal ribs for lateral reinforcement and with integral fibers linking the metal ribs for reinforcment against longitudinal stretch. Seal is installed in compression in a space between adjacent members, such as paving or wall members, which space may vary with thermal expansion and contraction of such sections. As installed between paving members, seal is nominally rectangular in cross-section with generally curved upper and lower support walls, which are resilient and adapted to selectively resist buckling from horizontal compression when installed in compression between such sections, and with generally vertical sealing side walls adapted to be urged into sealing relation against adjacent vertical surfaces by the resistance to compression of such support walls. Metal ribs are vertically disposed in side walls and shaped to uniformly transmit force from support walls across the sealing faces of side walls and to restrain such sealing faces from vertical expansion when support walls are placed in horizontal compression. Linking fibers restrain seal from stretch during fabrication and subsequent use.
