Abstract: A shielding door for an electromagnetically shielded room. The door has a door panel which is hingedly mounted. Attached to the door panel is a sheet-metal shroud which is movable between a closed-door position remote from the panel and an open-door position near the panel.

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 fireproof building element comprises a panel of nonflammable nonmetallic material, specifically glass, surrounded by an at least partly metallic framework with legs of rectangular cross-section divided by the plane of a surface of the panel into two frame portions together defining a recess accommodating an edge of the panel. One or both frame portions form at least one chamber, externally bounded by sheet metal with a wall thickness of not less than one millimeter, adjacent an external face of the framework paralleling the panel. Except for certain intermediate sections at or near the plane of the panel, which may be made of nonmetallic material of heat-insulating character, the framework consists virtually in its entirety of aluminum. The legs of the framework may be laterally split into separably interfitting inner and outer frame members each formed with a pair of chambers on opposite sides of the dividing plane.
