EXPANSION JOINT SYSTEM AND EXPANSION JOINT
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.
SELF-CLEANING EXPANSION JOINT SYSTEM
An expansion joint system for bridging a gap between spaced apart structural members and capable of self-cleaning. The expansion joint system includes first and second base members, at least one upwardly sloped base plate engaged with one of the first and second base members, and at least one substantially horizontal movable plate engaged with at least one of the first and second base members. Also disclosed is an expansion joint including a first structural member and a second structural member, first and second base members, at least one upwardly sloped base plate engaged with one of the first and second base members, and at least one substantially horizontal movable plate engaged with at least one of the first and second base members. Also disclosed is an expansion joint for a bridge or roadway including first and second structural members, first and second base members, at least one upwardly sloped base plate engaged with at least one of the first and second base members, and at least one substantially horizontal movable plate.

Finger-type expansion joint device without drainage sheet
Provided is a finger type expansion joint not having a drainage sheet, including: first and second support members (10, 10); a connection block plate (20); and a gap maintenance member (30).

Expansion joint system
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.
FINGER JOINT WITH A BRIDGING COVER PLATE
Disclosed is a finger joint having a bridging cover plate, which enables a steel plate having a thickness much smaller than that of a conventional finger to be used and allows the vertical rotation of an upper bridge structure. The finger joint includes: a bridging cover plate installed on a first structure and supported to a second structure across a gap so as to support a load of a vehicle passing over the gap, and configured to allow relative movement between the first structure and the second structure in a direction in which the distance of the gap changes; a first finger unit connected to the bridging cover plate; and a second finger unit installed on the second structure so as to allow relative movement relative to the first finger unit in a direction in which the distance of the gap changes.
Waterproof expansion joint
A waterproof expansion joint comprises a ballast protection plate and at least one locating device configured to retain the ballast protection plate over a deck joint. A flexible sealing member located below the ballast protection plate can include at least one flange portion and at least one expansion feature. Each expansion feature can include a shape preformed into the flexible sealing member extending downward into the deck joint and configured to deflect, enabling variation in the width of the flexible sealing member to match the width of the deck joint.
Bridge expansion joint
In a bridge expansion joint, a pair of lower plates is disposed between one bridge deck section and the other bridge deck section with leaving a predetermined interval. An upper plate is respectively disposed on an upper surface of the lower plate, in which the width of the upper plate in the horizontal direction is smaller than that of the lower plate. A load supporting means is disposed on the upper surface of the upper plate. The load supporting means comprises a pair of link members or a pair of finger members. A reinforced plate is disposed between the load supporting means and the lower plate, in which an inclined plane is respectively provided at both sides of the reinforced plate so that the reinforced plate has a narrow top and wide bottom-shaped section.
