Plate of composite construction material, column of a laminated glazing construction material, and method for the manufacture of such a column

摘要

A plate of composite material comprising elements of glass and a thermoplastic polymer adhering to the glass. The glass is toughened and the plate is assembled from adjacent and at least partly overlapping and cemented together elements which are each assembled of at least the toughened glass, and the thermoplastic polymer adhered to the glass. The glass is toughened to at least double the strength of non-toughened glass and to at most 50 % of the maximum strength of toughened glass.
