Abstract

A fire barrier operable to be placed within a gap formed between two surfaces. The fire barrier may generally include a first intumescent section, a first foam section coupled with the first intumescent section, and a second intumescent section coupled with the first foam section generally opposite the first intumescent section. In some embodiments, the fire barrier may include a plurality of intumescent sections and a plurality of foam sections with each foam section being positioned between at least two of the intumescent sections.

Claims

1. A building structural assembly comprising:

a first building element including a first face, an opposing second face, and an end face positioned therebetween at an edge of the first face and the second face;

a second building element including a first face, an opposing second face, and an end face positioned therebetween at an edge of the first face and the second face, wherein the first building element and the second building element are spaced apart from one another and form a gap therebetween; and

a fire barrier positioned in the gap, the fire barrier including;

a first intumescent section including a first outer surface wherein the entire first outer surface is in direct contact with the end face of the first building element and further including a first inner surface opposite the first outer surface,

a first foam section coupled directly with the first inner surface of the first intumescent section with no intervening layers of other material, and

a second intumescent section including a second outer surface wherein the entire second outer surface is in direct contact with the end face of the second building element and a second inner surface opposite the second outer surface coupled directly with the first foam section generally opposite the first intumescent section with no intervening layers of other material.

2. The assembly of claim 1, wherein the first intumescent section is smaller in width than the end face of the first building element.

3. The assembly of claim 1, wherein the first foam section is smaller than or equal in width to the first intumescent section and the second intumescent section.

4. The assembly of claim 1, wherein the second intumescent section is smaller in width than the end face of the second building element.

5. A building structural assembly comprising:

a first building element including a first face, an opposing second face, and an end face positioned therebetween at an edge of the first face and the second face;

a second building element including a first face, an opposing second face, and an end face positioned therebetween at an edge of the first face and the second face, wherein the first building element and the second building element are spaced apart from one another and form a gap therebetween; and

a fire barrier positioned in the gap, the fire barrier including;

a first intumescent section including a first outer surface wherein the entire first outer surface is in direct contact with the end face of the first building element and further including a first inner surface opposite the first outer surface,

a first foam section coupled directly with the first inner surface of the first intumescent section with no intervening layers of other material, and

a second intumescent section including a second outer surface wherein the entire second outer surface is in direct contact with the first face of the second building element and a second inner surface opposite the second outer surface coupled directly with the first foam section generally opposite the first intumescent section with no intervening layers of other material.

6. The assembly of claim 5, wherein the first intumescent section is smaller in width than the end face of the first building element.

7. The assembly of claim 5, wherein the first foam section is smaller than or equal in width to the first intumescent section and the second intumescent section.

8. The assembly of claim 5, wherein the second intumescent section is smaller in width than the first face of the second building element.
