Abstract
A preferred expansion joint fire barrier includes two sheets of metal having rows of dimples defined in the respective surfaces thereof with a layer of fire resistant material between the sheets to form a fire barrier body presenting a concave configuration, and includes a pair of attachment strips extending outwardly from opposed side edges of the barrier body.
Claims29
An expansion joint barrier comprising:
- a layer of barrier material;
- a sheet of metallic material forming an outer shell covering said layer of barrier material;
- and
- means for holding said layer and sheet in a superposed relationship,
- said sheet including a plurality of spaced dimples defined in the surface thereof, said dimples being separated by areas of undimpled planar surfaces therebetween.
An expansion joint fire barrier comprising:
- a sheet of high temperature, fire resistant metal presenting respective opposed edges;
- and
- a pair of spaced, parallel, attachment strips respectively coupled with said edges,
- said sheet including a plurality of dimples defined in the surface thereof and being configured to present a concave configuration, said dimples being separated by areas of undimpled planar surfaces therebetween.
The barrier as set forth in 22, said configuration including a V-shaped configuration.
The barrier as set forth in 22, said metal including stainless steel.
An expansion joint fire barrier comprising:
- first and second spaced metal sheets;
- a bendable layer of fire resistant material positioned between said sheets, said sheets and layer being congruent and cooperatively forming a fire barrier body presenting opposed side edges;
- and
- a pair of spaced, parallel attachment strips respectively coupled with said edges,
- each of said sheets including a plurality of dimples defined in the surface thereof and configured as a plurality of spaced rows of dimples for creating respective dimple zones resistant to bending and for creating respective undimpled planar areas between said rows with said undimpled planar areas presenting zones of bending weakness relative to said dimple zones for inducing bending of said sheet in said undimpled planar areas when said barrier is formed into a non-planar configuration,
- said body presenting a concave configuration for extending into and spanning the gap in an expansion joint, said sheet including score lines facilitating the formation of said configuration.
