    摘要: An expansion joint sealing system for bridging and sealing a gap located between two spaced-apart structural deck members. The expansion joint sealing system includes an elastomeric seal member and a substantially rigid plate member. The elastomeric seal member is fixedly attached to an underlying structural deck member and is able to expand and contract in the longitudinal direction in relation to the traffic direction across the expansion joint. The rigid plate is not fastened to the elastomeric seal member with mechanical fasteners or other fastening means, but is slidingly engaged with the elastomeric seal member through an elongated guide member. As the rigid plate member is not fastened to the elastomeric seal member, it is able to move along a guide member in a direction that is transverse to the direction of traffic across the expansion joint.

    摘要: An expansion joint seal for sealing a gap between two structural members that includes a coverplate, a snap-fit connector extending downwardly from the coverplate, a central spine connected to the coverplate with a snap-fit connector and extending downwardly from the connector, and foam seal members engaged with the central spine of the expansion joint seal. An expansion joint including spaced-apart structural members defining a gap between the spaced-apart members and the expansion joint seal.

    摘要: An expansion joint system for bridging a gap between spaced apart structural members and for accommodating transverse movement. The expansion joint system includes a plurality of finger plates carrying a plurality of elongated fingers that are configured to at least partially extend across an expansion joint gap from opposing structural members. The finger plates are pivotably mounted to the underlying structural members to permit pivoting or rotating movement in the transverse direction. A torsion spring is engaged with the pivotable finger plates and provides a restoring force to the finger plate when the finger plate rotates relative to the spring. Also disclosed is an expansion joint including spaced-apart structural members and the expansion joint system installed in the joint. The elongated fingers of the finger plates of the expansion joint system extend at least partially across the expansion joint gap from a first structural member and are interdigitated with elongated fingers extending from a opposing second structural member to provide a surface to traverse the expansion joint gap.

    摘要: A seismic expansion joint cover assembly installed at an expansion gap between a first structural member on one side of a gap and a second structural member on the opposite side of the gap including a cover panel bridging the gap having at least one connector joining one edge of the cover panel to the first structural component to allow movement of the cover panel. The expansion joint cover assembly includes at least one slide support, which attaches to the second structural member, and which includes a track having a lift component located on the track to lift the cover panel. The expansion joint cover assembly also includes a rider assembly for engaging with the track of the slide support. One or more spring assemblies are attached to the second structural member and the cover panel. The expansion joint cover assembly is mechanically latched when the system is in the normal service position, but has the capability of becoming unlatched in response to large displacements.
