Abstract
Abstract A load bearing multidirectional expansion joint seal structure including a peveral corner plate members adapted for connection in load bearing relation to the corners of adjacent deck sections at the intersection of the gaps between the deck sections, a center plate member vertically disposed in overlapping relation with respect to all of the corner plate members, and elastomeric support means disposed between and bonded to the faces of the overlapping portions of all the members. The support means provide vertical support between said overlapping portions and are adapted to deform in shear to accommodate respective relative horizontal movement between the corner plate members and the center plate member. Elastomeric interconnecting and facing means defines a substantially horizontal upper surface for vehicular traffic and defines grooves to permit relative horizontal movement between the members without compressive deformation of the support means.
