Fire resistant barrier for dynamic expansion joints
First Claim
1. A fire resistant barrier for architectural expansion joints comprising a plurality of fire resistant material layers comprising:
- a first mechanical support layer having a first and second major surface;
a second layer having a first and second major surface, wherein said second layer provides protection and mechanical support to said fire barrier;
at least one layer of intumescent sheet having a first and second major surface, wherein said at least one layer of intumescent sheet is disposed between said first mechanical support layer and said second layer; and
wherein said first mechanical, said second, and said intumescent sheet layers are locally bonded together only substantially along a longitudinal center and substantially continuously along the length of said layers.

Abstract
A fire resistant barrier and system for dynamic building expansion joints comprising a plurality of layers of fire resistant material comprising: a first mechanical support layer having a first and second major surface; a second layer having a first and second major surface, wherein the second layer provides protection and mechanical support to the fire barrier; and at least one layer of intumescent sheet material having a first and second major surface; said at least one layer of intumescent material is disposed between said first mechanical support layer and said second layer; and wherein said first mechanical support layer, said second layer and said at least one layer of intumescent material are locally bonded together over only a portion of their width substantially continuously along the length of the layers of said fire resistant material. The fire barrier is secured to concrete building members with retainer angle brackets and does not require the use of conventional caulking materials to effect a tight seal between the building structure and the fire barrier.
