Pane holder in all-glass facades

Claim 2

A glass supporting system in all-glass facades, comprising: a supporting structure; a holder element composed of a heat-resistant material and to be secured to said supporting structure, said holder element having a center web portion fixable to said supporting structure, said holder element also having an outer folded edge portion; and a plurality of glass pane zones located forwardly of said supporting structure and each having at least one straight outer pane with a plurality of surrounding peripheral edges defining an outside of the facade, said outer pane having means for accommodating said holder element, said accommodating means being formed by at least one of said surrounding peripheral edges having a step-shape cross-section defining a step provided in said outer pane and having a predetermined height, said folded edge portion of said holder element extending substantially parallel to a plane of said one outer pane and having a thickness which is smaller than said height of said step, said folded edge portion gripping in said step of said one outer pane from outside and not projecting outwardly beyond an outer surface of said one outer pane, so as to mechanically secure said one outer pane by said holder element, said step having an inner portion and an outer portion formed so that said outer portion is wider than said inner portion.

Claim 3

The system as defined in claim 1, wherein each of said pane zones has multi-layers of laminated glass panes, at least one of said multi-layers having said step-shape cross-section facing toward the outside of the facade.

Claim 4

The system as defined in claim 1, wherein each of said pane zones has a single-layer pane having a partial cross-section facing toward the outside of the facade which is said step-shape cross-section.

Claim 5

The system as defined in claim 1, wherein each of said pane zones has an insulating glass unit, said glass unit including at least two individual panes spaced apart from each other, an outer one of said two individual panes forming said step-shape cross-section.

Claim 6

The system as defined in claim 4, wherein said outer one of said two individual panes is composed of laminated glass pane.

Claim 7

The system as defined in claim 4, wherein said outer one of said two individual panes is composed of a single-layer glass pane.

Claim 8

The system as defined in claim 1, wherein said plurality of surrounding peripheral edges has a second edge that runs parallel to said at least one of said peripheral edges, said second edge being formed offset with a step-shape cross-section.

Claim 9

The system as defined in claim 1, wherein said plurality of surrounding peripheral edges has four edges each being offset with a step-shape cross-section that runs around all four of said plurality of surrounding peripheral edges.

Claim 10

The system as defined in claim 1, wherein said holder element is formed of a plurality of members spaced at a predetermined distance from each other along one of said surrounding peripheral edges of each of said pane zones.

Claim 11

The system as defined in claim 1, wherein said holder element is composed of elastic material.

Claim 12

The system as defined in claim 1, wherein said holder element is composed of metal.

Claim 13

The system as defined in claim 1, wherein said holder element is composed of a poor heat conductor.

Claim 14

The system as defined in claim 9, wherein said two adjacent outer panes define a gap therebetween; and further comprising means for closing said gap.

Claim 15

The system as defined in claim 20, wherein said closing means includes a sealing compound.

Claim 16

The system as defined in claim 20, wherein said closing means includes a cover cap.

Claim 17

The system as defined in claim 1, wherein each of said pane zones has an edge length, said holder element being formed in one piece and covering said edge length of at least one of said pane zones.

Claim 18

A a glass supporting system in all-glass facades, comprising: a supporting structure; a holder element composed of a heat-resistant material and to be secured to said supporting structure, said holder element having a center web portion fixable to said supporting structure, said holder element also having an outer folded edge portion; and a plurality of glass pane zones located forwardly of said supporting structure and each having at least one straight outer pane with a plurality of surrounding peripheral edges defining an outside of the facade, said outer pane having means for accommodating said holder element, said accommodating means being formed by at least one of said surrounding peripheral edges having a step-shape cross-section defining a step provided in said one outer pane, and said folded edge portion of said holder element gripping in said step of said outer pane from outside and not projecting outwardly beyond an outer surface of said one outer pane, so as to mechanically secure said one outer pane by said holder element, said plurality of glass pane zones each having at least two glass panes, outer panes of each of said at least two glass panes being arranged adjacent to each other to constitute two adjacent outer panes, said two adjacent ouer panes having one of said surrounding peripheral edges adjacent to each other so as to constitute adjacent peripheral edges, said adjacent peripheral edges each having an inner portion and an outer portion, said outer portion having said stepshape cross-section, said inner portion of each of said adjacent peripheral edges being spaced apart from each other to define an inner distance free of said step-shape crosssection, said outer portion of each of said adjacent peripheral edges being spaced apart to define an outer distance greater than said inner distance.

Claim 19

A a glass supporting system in all-glass facades, comprising: a supporting structure; a holder element composed of a heat-resistant material and to be secured to said supporting structure, said holder element having a center web portion fixable to said supporting structure, said holder element also having an outer folded edge portion; and a plurality of glass pane zones located forwardly of said supporting structure and each having at least one straight outer pane with a plurality of surrounding peripheral edges defining an outside of the facade, said outer pane having means for accommodating said holder element, said accommodating means being formed by at least one of said surrounding peripheral edges having a step-shape cross-section defining a step provided in said one outer pane, and said folded edge portion of said holder element gripping in said step of said outer pane from outside and not projecting outwardly beyond an outer surface of said one outer pane, so as to mechanically secure said one outer pane by said holder element, said plurality of glass pane zones each having at least two glass panes, outer panes of each of said at least two glass panes being arranged adjacent to each other to constitute two adjacent outer panes, said two adjacent ouer panes having one of said surrounding peripheral edges adjacent to each other so as to constitute adjacent peripheral edges, said adjacent peripheral edges each having an inner portion and an outer portion, said outer portion having said stepshape cross-section, said inner portion of each of said adjacent peripheral edges being spaced apart from each other to define an inner distance free of said step-shape crosssection, said outer portion of each of said adjacent peripheral edges being spaced apart to define an outer distance greater than said inner distance.
