Abstract
The invention relates to a fireproofing element comprising a fireproof glazed element (1) which forms a window or door leaf (8). A bulkhead frame (3) is arranged around the door leaf (8), inserted in the building (2). A deformable component (28) is built in between the bulkhead frame (3) and the building (2). At least one telescopic element (15) is arranged between a lateral edge (10) of the door leaf (8) and the bulkhead frame (3). Said telescopic element (15) is displaceable relative to the bulkhead frame (3) in the direction of the arrows (20). The telescopic element (15) can compensate for changes in the joint (50) between the door leaf (8) and the bulkhead frame (3) and/or also seal said joint (50). Changes in length as a result of heating of the components during a fire can thus be accommodated and the door leaf (8) and fireproofing glazed element (1) hence not destroyed.
