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 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.

摘要： A 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. According to an aspect, the system comprises open celled foam having a water-based acrylic chemistry infused therein. A layer of an elastomer is disposed on the open celled foam and is tooled to define a profile to facilitate the compression of the expansion joint system when installed between coplanar substrates. The system is delivered to a job site in a pre-compressed state ready for installation into the building joint.

摘要： An expansion joint seal includes a central portion having at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. When installed on the structure, the first flange portion is attachable to a first substrate of the structure and the second flange portion is attachable to a second substrate of the structure such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure. Movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.
