Abstract: The invention concerns the provision of structural elements for building facades and the like, which are provided for fire protection according, for example, to German Industrial Standard requirements. Accordingly, measures should be provided for self-supporting fire protection elements which prevent the spreading of fire, for example, from floor to floor, regardless of whether the fire comes from the outside or the inside. This object is achieved in that the composite connecting body (4) consists of at least one statically loadable bearing body having an aluminum core (18) which is completely or partially surrounded by fire suppressant material (9). This fire suppressant material (9) can be provided with or without a covering (10).

Abstract: A flame window adapted to serve window separating a flame side from another side of a structure or vehicle or as a viewing window for a firebox or the like comprises a frame in which a lime-soda-silicate (soda-lime) glass is anchored by clamping all around its periphery in a heat-insulating bed. The soda-lime glass has a product of thermal coefficient of linear expansion and modulus of elasticity which is greater than 0.5 N.multidot.mm.sup.-2 .multidot.k.sup.-1.
