ABSTRACT:
This invention relates to a novel, and improved expansion joint and seal for use in sealing concrete expansion joints. In general the device is constituted of an elongate flexible seal member inclusive of an expandable loop portion from the non-closed sides of which a pair of alternately disposed downwardly projected leg portions are extended. The device also includes a pair of elongate side frames, each of which is attached to an alternately disposed downwardly projected leg portion of said elongate flexible seal member, and a removable, elongate top cap for affixing upon the loop portion of said elongate flexible seal member. The improvement relates to, inter alia, in said member, side frames which contain one or more pairs of inwardly sloped laterally aligned ribs which form longitudinal channels with relatively wide bottom surfaces with restricted surface outlets, the channel forming a means of tenaciously bonding plastic cement to said side frames to form a flexible seal. The side frames also include upwardly faced deep U-shaped slots within which each of the leg portions of said expandable loop portion of the elongate flexible seal is extended, and bonded by use of adhesive.
