Abstract

An approved dynamic construction is used for effectively thermally insulating and sealing of a sating slat between a floor of a building and an exterior wall construction. The exterior wall construction includes a curtain wall configuration defined by an interior wall glass surface, including one or more aluminum framing members. In particular, a process is useful for assembling a fireproof system within a stick build exterior dynamic curtain wall façade, which includes glass, especially vision glass extending to the finished floor level below.

First claim

The invention claimed is:

1. A fireproof system within a stick build exterior dynamic curtain wall façade, the fireproof system including at least a first L-shaped member, a second L-shaped member, and a thermally resistant material, wherein the fireproof system is assembled according to a process comprising:
assembling a framing structure by attaching one or more anchoring brackets to horizontal framing members and vertical framing members and to concrete and steel members of the façade to a building structure;
installing one or more appropriate water gasket seals to the framing members to seal the framing structure and building structure from water intrusion;
installing the first L-shaped member of a non-combustible material, having a first leg and a second leg perpendicular to each other, and the second L-shaped member of a non-combustible material, having a first leg and a second leg perpendicular to each other, such that the first leg of the first L-shaped member is fastened to an upper said horizontal framing member and an upper location of the vertical framing members and the first leg of the second L-shaped member is connected to the second leg of the first L-shaped member, thereby forming a substantially U-shaped cavity;
installing one or more supporting or attachment elements to fasten the substantially U-shaped cavity to an inner facing side of the vertical framing member, thereby forming a 5-sided box pan;
installing at least one additional element selected from the group consisting of gaskets, hardware, and components necessary to prepare the framing structure for glass installation;
completing the curtain wall façade by installing glass and one or more appropriate sealing layers to the façade;
installing the thermally resistant material into the substantially U-shaped cavity and a safing slot; and
optionally, applying an outer fire retardant coating positioned across the thermally resistant material installed in the safing slot and adjacent portions of the vertical and horizontal framing members and a floor located thereadjacent.

2. The fireproof system according to claim 1 , wherein the first L-shaped member and the second L-shaped member are comprised of a metal material.

3. The fireproof system according to claim 1 , wherein the first L-shaped member and the second L-shaped member are comprised of an 18 gauge galvanized steel material.

4. The fireproof system according to claim 1 , wherein the substantially U-shaped cavity is fastened by at least one element selected from the group consisting of a pin, an expansion anchor, a screw, a screw anchor, a bolt, and an adhesion anchor.

5. The fireproof system according to claim 1 , wherein the supporting or attachment elements have a substantially L-shaped profile and are positioned so that a gap between the substantially U-shaped cavity and the vertical framing member is closed due to an architectural structure of the stick build exterior dynamic curtain wall façade.

6. The fireproof system according to claim 1 , wherein the thermally resistant material is a thermally resistant flexible mineral wool material to facilitate placement thereof into the substantially U-shaped cavity.

7. The fireproof system according to claim 1 , wherein the 5-sided box pan has a depth of about 3 inches and a height of about 6 inches.

8. The fireproof system according to claim 1 , wherein a back of the substantially U-shaped cavity is positioned spatially disposed from the interior wall surface of the stick build exterior dynamic curtain wall façade.

9. The fireproof system according to claim 1 , wherein the stick build exterior dynamic curtain wall façade comprises a vision glass and wherein the back of the substantially U-shaped cavity is positioned spatially disposed from the inner surface of the vision glass infill.

10. The fireproof system according to claim 1 , wherein the outer fire retardant coating is applied, and wherein the outer fire retardant coating has a wet film thickness of about 2 mm to about 3.175 mm (⅛ inch).

11. The fireproof system according to claim 1 , wherein the outer fire retardant coating is applied, and wherein the outer fire retardant coating is a water-based outer fire retardant coating or silicone-based outer fire retardant coating.

12. The fireproof system according to claim 1 , wherein the outer fire retardant coating is applied, and wherein the outer fire retardant coating is in at least one form selected from the group consisting of an emulsion, a spray, a coating, a foam, a paint, and a mastic.

13. The fireproof system according to claim 1 , wherein the fireproof system is an acoustic insulating and sealing system.

14. A stick build exterior dynamic curtain wall façade, comprising:
the fireproof system assembled according to claim 1 ,
a vision glass infill, and
one or more appropriate sealing layers.

15. A building construction, comprising:
a curtain wall construction defined by an interior wall surface including one or more framing members, and
at least one floor spatially disposed from the interior wall surface of the curtain wall construction, thus defining a safing slot extending between the interior wall surface of the curtain wall construction and an outer edge of the at least one floor,
wherein the curtain wall construction comprises the fireproof system assembled according to claim 1 .
