US Patent 7784234 Fire stop clamp

A fire stop clamp is presented. The fire stop clamp includes a support clamp and a fire stop disc. The support clamp supports a pipe by preventing movement of a pipe towards a structural member. The fire stop disc seals an opening associated with a pipe penetration. The sealed opening inhibits the passage of fire and smoke through the opening. The fire stop clamp includes an expansion element that pushes the fire stop disc towards the structural member. If a pipe moves away from the structural member, the expansion element will allow the fire stop disc to retain a seal over the opening.
