Abstract

A glazing assembly for a curtain wall glazing system comprising a glazing unit and a frame structure formed by a plurality of glazing profiles. Each of the plurality of glazing profiles comprises a main structural frame part and a removable clamping part. The removable clamping parts when removed from the structural frame parts unclamp the glazing unit and open a clearance allowing removal of the glazing unit in a direction of a first area. At least one of the main structural frame parts comprises a structural portion and a mobile clamping portion. When removing the mobile clamping portion from the structural frame portions a clearance is opened allowing the performance of maintenance activities to an edge region of the glazing unit from the second area.

First claim

The invention claimed is:

1. A glazing assembly for a curtain wall glazing system separating a first area from a second area, comprising:
a first glazing unit comprising a first glass surface for facing said first area and a second glass surface for facing said second area,
a plurality of glazing profiles forming a frame structure for said first glazing unit,

and wherein each glazing profile comprises
a main structural frame part, and
a removable clamping part removably coupled to the main structural frame part by a fastener,
wherein said first glazing unit is clamped between the main structural frame parts and the removable clamping parts of said plurality of glazing profiles, with the first glass surface linked with the removable clamping part, and the second glass surface linked with the main structural frame part,
wherein an uncoupling of the removable clamping parts from the corresponding main structural frame parts for each glazing profile unclamps the first glazing unit and opens a clearance allowing the removal of the first glazing unit in a direction of the first area,
wherein at least one main structural frame part of said plurality of glazing profiles further comprises
a structural portion, and
a mobile clamping portion removably coupled by a fastener to said structural portion, and linked with the second glass surface, and
wherein the removal of the mobile clamping portion from the structural portion for said at least one main structural frame part, opens a clearance allowing maintenance activities to be performed near an edge region of the first glazing unit from said second area.

2. The glazing assembly according to claim 1 , wherein the glazing profile that comprises said at least one main structural frame part, comprises an inner channel enclosing cabling and/or electric components or electronic components.

3. The glazing assembly according to claim 2 , wherein the removal of the mobile clamping portion from the structural portion which opens the clearance allows access to said inner channel for performing maintenance activities on the cabling and/or electric components or electronic components.

4. The glazing assembly according to claim 1 , wherein said mobile clamping portion is removably coupled with said structural portion using screws or bolts or a click attachment system.

5. The glazing assembly according to claim 1 , wherein said first glazing unit is an insulating glazing unit or a single glazing unit or a laminated glazing unit.

6. The glazing assembly according to claim 1 , wherein said first glazing unit is a fixed glazing unit.

7. The glazing assembly according to claim 1 , wherein said first glazing unit has a rectangular shape and wherein a first and a second glazing profile of said plurality of glazing profiles corresponds to a pair of mullions placed in parallel and wherein a third and a fourth glazing profile of said plurality of glazing profiles corresponds to a pair of transoms placed in parallel.

8. The glazing assembly according to claim 7 , comprising a second glazing unit positioned adjacent to said first glazing unit and sharing therewith a common mullion or transom, which is configured for receiving an edge of the first glazing unit and for receiving an edge of the second glazing unit in an adjacent configuration, wherein the first and second glazing units are separated by said common mullion or transom.

9. The glazing assembly for a curtain wall glazing system according to claim 1 , wherein each of the main structural frame parts of said plurality of glazing profiles comprises
a structural portion, and
a mobile clamping portion removably coupled to said structural portion, and linked with the second glass surface, and
wherein the removal of the mobile clamping portion from the structural portion for each of the main structural frame parts unclamps said first glazing unit and opens a clearance allowing the removal of said first glazing unit in a direction of the second area and/or allows maintenance activities to be performed near edge regions of the first glazing unit from said second area.

10. The glazing assembly according to claim 9 , further comprising a first peripheral gasket secured between said first glass surface and the removable clamping parts of said plurality of glazing profiles.

11. The glazing assembly according to claim 10 , further comprising a second peripheral gasket secured between said second glass surface and the mobile clamping portions of said plurality of glazing profiles.

12. The glazing assembly according to claim 9 , wherein the removal of the mobile clamping portion from the structural frame portion for each of the main structural frame parts of said plurality of glazing profiles, unclamps said first glazing unit and opens a clearance allowing the removal of said first glazing unit in the direction of said second area by a rotation of said first glazing unit about an edge thereof, or by a translation in the direction of the second area, or by a combination of rotation and translation.

13. A curtain wall glazing system, comprising the glazing assembly of claim 1 .

14. A glazing panel for an unitizing façade system, comprising glazing assembly according to claim 1 .

15. A method for performing a maintenance activity near at least one edge region of a first glazing unit from a curtain wall glazing system that is separating a first area from a second area, and wherein said glazing system comprises a glazing assembly according to claim 1 , said method comprising:
selecting whether the maintenance activity is to be performed from the first area or form the second area,
if the maintenance activity is to be performed from the first area then
a) for one or more of said plurality of glazing profiles uncoupling the clamping parts from the structural frame parts, thereby opening a clearance to said edge region,
b) performing said maintenance activity from said first area,
if the maintenance activity is to be performed from the second area then
a) removing the mobile clamping portion from the structural portion for said at least one main structural frame part, thereby opening a clearance to said edge region,
b) performing said maintenance activity from said second area.

16. The glazing assembly according to claim 1 , wherein the mobile clamping portion is removable while the removable clamping part is coupled to the main structural frame part, and the removable clamping part is removable while the mobile clamping portion is coupled to the structural portion.

17. A glazing assembly for a curtain wall glazing system separating a first area from a second area, comprising:
a first glazing unit comprising a first glass surface for facing said first area and a second glass surface for facing said second area,
a plurality of glazing profiles forming a frame structure for said first glazing unit,

and wherein each glazing profile comprises
a main structural frame part, and
a removable clamping part removably coupled to the main structural frame part by a fastener,
wherein said first glazing unit is clamped between the main structural frame parts and the removable clamping parts of said plurality of glazing profiles, with the first glass surface linked with the removable clamping part, and the second glass surface linked with the main structural frame part,
wherein an uncoupling of the removable clamping parts from the corresponding main structural frame parts for each glazing profile unclamps the first glazing unit and opens a clearance allowing the removal of the first glazing unit in a
