Building glass facade of a building, a clamping arrangement for holding glass panels in a glass facade of a building, a brace to hold safety glass panels in a glass facade of a building, and a brace to hold safety glass panels

Abstract

A building glass facade of a building comprising a plurality of glass elements covering at least a portion of a building, wherein at least one of the glass elements comprises a safety glass panel. The glass elements have a brace to hold the safety glass panels that comprise at least two glass plates whereby there is an invisible protection against falling out, which is achieved by a separating or connecting film that is positively and non-positively connected with the braces by a film that is in the form of a separating or connecting film. The brace also has a type of fastening such that there is a permanently elastic medium for stress-free installation.
