Fire and water resistant expansion and seismic joint system
First Claim
1. A fire and water resistant expansion and seismic joint system, comprising:
- a cover plate;
a spline attached to the cover plate;
a core having a fire retardant material infused therein located on a first face and a second face of the spline;
wherein 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; and
wherein the core is compressible between the first face of the spline and one of the substrates and is compressible between the second face of the spline and the other of the substrates, and wherein the fire retardant infused core has a density when compressed of about 160 kg/m3 to about 800 kg/m3, and the fire and water resistant expansion and seismic joint system and the fire retardant infused core are capable of withstanding exposure to a temperature of about 540°
C. at about five minutes, and the fire retardant infused core is configured to pass testing mandated by UL 2079.

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.
