  • Patent number: 8870506
    Abstract: A system configured to anchor a cover plate over an interface formed between substantially coplanar substrates includes a sleeve capable of being anchored in a first substrate; a spring located in the sleeve; a post located in communication with the spring; and a fastener secured onto the post. A head of the post is located in the sleeve, and an end of the post opposite the head of the post extends out of the sleeve to receive the fastener. The fastener is secured onto the post over the cover plate located on the first substrate such that the cover plate extends over the interface formed between the first and second substrates when they are positioned to be substantially coplanar.

  • Patent number: 8813450
    Abstract: A fire and water resistant expansion and seismic joint system has a cover plate; a spline attached to the cover plate along a first edge of the spline; and a core comprising a first core portion and a second core portion, each portion being located on an opposing face of the spline. The first core portion and the second core portion have a fire-retardant material infused therein. The spline depends from the cover plate in a one piece construction and extends into the core to a depth within the core, and is positioned in a gap between substantially coplanar substrates such that the cover plate overlies the gap. Each portion of the core is compressed between a respective face of the spline and a face of one of the coplanar substrates.

  • Patent number: 8813449
    Abstract: A fire and water resistant expansion joint system has a cover plate; a spline attached to the cover plate along a first edge of the spline; and two portions of foam, each portion being located on an opposing face of the spline. The foam has a fire-retardant material infused therein. The spline depends from the cover plate and is positioned in a gap between substantially coplanar substrates such that the cover plate overlies the gap. Each portion of the foam is compressed between a respective face of the spline and a face of one of the coplanar substrates.

  • Patent number: 8739495
    Abstract: 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.
