摘要： A fire and/or water resistant expansion joint system for installation into a building joint in vertical and horizontal configurations is designed such that it can be used for either an inside or outside corner. The system comprises a core having a fire retardant therein. A layer of a water resistant material is disposed on the core to facilitate the compression of the expansion joint system when installed between substrates. The system can be delivered to a job site in a pre-compressed state ready for installation into the building joint.

摘要： An expansion joint system includes a cover plate; a spline attached to the cover plate; and foam having a fire retardant material included therein in an amount effective to pass testing mandated by UL 2079. The spline depends from the cover plate and is configured to be positioned in a gap between substrates such that the cover plate overlies the gap. The foam is compressible between a first face of the spline and one of the substrates and the foam is compressible between a second face of the spline and the other of the substrates, and the expansion joint system is configured to facilitate compression of the foam when installed between the substrates by repeatedly expanding and contracting to accommodate movement of the substrates; and the foam with the fire retardant material included therein is configured to pass the testing mandated by UL 2079.

摘要： A water resistant expansion joint system includes foam, which has been formed into a desired shape by at least one of stamping, cutting, molding and die-cutting; and a layer of an elastomer disposed on the foam. The layer of the elastomer facilitates compression of the water resistant expansion joint system when installed between substrates. The desired shape of the foam includes an angle, and the water resistant expansion joint system is angled around a corner and accommodates thermal and seismic movement in the system by expanding and contracting, and creates a waterproof seal around the corner upon expansion of the foam between the substrates.

摘要： A fire resistant and water resistant expansion joint system comprises a compressed lamination of fire retardant infused open celled foam, one coat of an elastomeric waterproofing or water resistant material on the lamination, and another coat of an intumescent material on an opposing surface of the lamination, thereby providing fire resistance in one direction and water resistance in the opposite direction. The intumescent material may be further coated with a similar elastomeric material, thereby providing fire resistance in one direction and water resistance in both directions. In the alternative, the compressed lamination may comprise first and second opposing layers of intumescent material thereon each having a respective layer of elastomeric material to provide both water resistance and fire resistance in both directions.

摘要： A fire and/or water resistant expansion joint system for installation between substrates of a tunnel. The system includes a fire resistant coating applied at a predetermined thickness to achieve a substantially uniform layer on the substrates and a fire and water resistant expansion joint. The expansion joint includes a core having an edge, wherein the substantially uniform layer of the coating extends along the substrates of the tunnel to the edge of the core, and a fire retardant infused into the core. The core is configured to facilitate the compression of the expansion joint system when installed between the substrates. The coating and the fire and water resistant expansion joint are each capable of withstanding exposure to a temperature of at least about 540° C. or greater for about five minutes.
