Fire stop system
First Claim
1. A fire stop system with a pass through device installed in a structural opening, the fire stop system comprising:
- a split pipe having a first end and a second end, wherein the first end and the second end have an intumescent material installed thereon for sealing the split pipe when exposed to elevated temperatures;
a foam wall gasket installed around the split pipe adjacent the structural opening, wherein the foam wall gasket forms a contour to the structural opening blocking air flow between the split pipe and the opening;
an annulus plate covering the foam wall gasket, wherein the annulus plate is positioned around the split pipe at the structural opening;
a hot sock install around the split pipe, wherein the hot sock has a base and a top; and
a spring ring secured to the base of the hot sock, wherein the spring secures the hot sock to the split pipe,wherein the first end and the second end of the split pipe have a pocket, wherein the pocket receives the spring ring to secure the hot sock to the split pipe.

Abstract
A fire stop system with a pass through device is installed in a structural opening. The fire stop system includes a split pipe, a foam wall gasket and an annulus plate. The split pipe includes a first end and a second end. The first end and the second end have an intumescent material installed thereon to seal the split pipe when the split pipe is exposed to elevated temperatures. The foam wall gasket is installed around the split pipe adjacent the structural opening. The foam wall gasket forms a contour to the structural opening blocking air flow between the split pipe and the opening. The annulus plate covers the foam wall gasket and is installed around the split pipe at the structural opening.

22. A fire stop system with a pass through device installed in a structural opening, the fire stop system comprising:
-
a split pipe having a first end and a second end, wherein the first end and the second end have an intumescent material installed thereon for sealing the split pipe when exposed to elevated temperatures, wherein the first end and the second end of the split pipe have an alignment tab and a pocket, wherein the alignment tab is positioned in the pocket when the split pipe is closed to restrict lateral movement of the split pipe, wherein the pocket has a smooth edge and the intumescent material is installed adjacent to the pocket, whereby the smooth edge of the pocket protects the intumescent material installed in the split pipe; a foam wall gasket installed around the split pipe adjacent the structural opening, wherein the foam wall gasket forms a contour to the structural opening blocking air flow between the split pipe and the opening; and an annulus plate covering the foam wall gasket, wherein the annulus plate is positioned around the split pipe at the structural opening. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)

31. A fire stop system with a pass through device installed in a structural opening, the fire stop system comprising:
-
a split pipe having a first end and a second end, wherein the first end and the second end have an intumescent material installed thereon for sealing the split pipe when exposed to elevated temperatures; a foam wall gasket installed, around the split pipe adjacent the structural opening, wherein the foam wall gasket forms a contour to the structural opening blocking air flow between the split pipe and the opening; and an annulus plate covering the foam wall gasket, wherein the annulus plate is positioned around the split pipe at the structural opening, wherein the annulus plate has two identical semicircular halves, each half having a catch pocket at one end and a locking mechanism at an opposite end, wherein the catch pocket has an opening for engaging the locking mechanism, wherein the locking mechanism has a retaining tab, a locking tab and a stabilizing tab, wherein the retaining tab and the locking tab oppose each other and deflect into locking engagement with the catch pocket. - View Dependent Claims (32, 33, 34, 35, 36)
