Building façade structure with joined pultruded elements
A building element includes a glass panel defining an outer circumferential rim including at least two rectilinear segments, a first one of which defines a first length and a second one of which defines a second length. The glass panel is made of hardened glass and has a specific coefficient of thermal expansion. The building element further includes a first pultruded element having a length corresponding to the first length, and a second pultruded element having a length corresponding to the second length. The first and second pultruded elements are adhered in a high strength integral adhesion to the hardened glass panel along the first and second rectilinear segments, respectively, and the pultruded elements have a content of reinforcing fibers for providing a coefficient of thermal expansion of the pultruded elements substantially corresponding to the specific coefficient of thermal expansion.
1. A façade structure for a building structure, comprising:
at least first and second building elements, each of the building elements comprising:
a self-supporting glass panel defining an outer circumferential rim including at least two rectilinear segments, a first one of which defines a first length and a second one of which defines a second length, said self-supporting glass panel having a specific coefficient of thermal expansion; and
a first pultruded element having a length corresponding to said first length and a second pultruded element having a length corresponding to said second length, said first and second pultruded elements being adhered in a high strength integral adhesion to said self-supporting glass panel along said first and second rectilinear segments, respectively;
wherein each of said first and second pultruded elements has a content of reinforcing fibers for providing a coefficient of thermal expansion of said pultruded elements substantially corresponding to said specific coefficient of thermal expansion;
wherein said first and second building elements are joined together by one of said first and second pultruded elements of said first building element and one of said first and second pultruded elements of said second building element.

3. The facade structure according to claim 1 , wherein the difference between the coefficient of thermal expansion of said pultruded elements and said specific coefficient of thermal expansion is less than 40%.
4. The facade structure according to claim 1 , wherein the content of fibers of said pultruded elements is more than 40% by weight.
5. The facade structure according to claim 1 , wherein said first and second pultruded elements are adhered to said self-supporting glass panel by means of at least one of a PU adhesive and an epoxy adhesive.
6. The facade structure according to claim 1 , wherein said self-supporting glass panel is a rectangular panel, and said first and second rectilinear segments constitute the opposite longer sides of said rectangular glass panel.
7. The facade structure according to claim 1 , wherein said self-supporting glass panel is a first self-supporting glass panel, and wherein each of said building elements further comprises a second self-supporting glass panel positioned in a spaced apart relationship relative to said first self-supporting glass panel by a plurality of distance elements.
8. The facade structure according to claim 7 , wherein each of said distance elements comprises an extension of one of said first and second pultruded elements.
9. The facade structure according to claim 8 , wherein each of said distance elements further includes a vapor absorbing substance.
10. The facade structure according to claim 8 , further including a gas tight foil between said first and second self-supporting glass panels.
11. The facade structure according to claim 10 , wherein said gas tight foil is integrally included within each of said distance elements.
