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.
