Fire-inhibiting flat element comprising at least two transparent fire-resisting glass plates

Fire-retardant sheet element (1) with at least two transparent fire protection glass plates (2, 3, 4), which abut one another on lateral edges (9, 10;

• 14, 15) and the remaining lateral edges (11, 12, 13) are therein held on a structural part (6), wherein these fire protection glass plates (2, 3, 4) are comprised of at least two glass panes (16) disposed parallel and spaced apart, and a fire protection layer (18) disposed in the interspace (17) between these glass panes (16), and between the abutting lateral edges (9, 10;
• 14, 15) of the glass plates (2, 3, 4) a sealing configuration (7, 8) is installed, whereby the abutting lateral edges (9, 10;
• 14, 15) of the glass plates (2, 3, 4) are disposed at a spacing of at least 1 mm with respect to one another and the sealing configuration (7, 8) is disposed in this interspace (26) between the lateral edges (9, 10;
• 14, 15) and over its entire length and comprises a sealing element (23, 24, 25), the improvement comprising that the fire protection layer (18) between the glass panes (16) does not extend up to the edge (9-15) of the glass plate (2, 3, 4) and along the margin region a groove (19) is developed, and that this groove (19) in the margin region between the glass panes (16) is filled with a barrier material (20).
