Support structure for fixing fire-resistant glazing

摘要

The invention relates to a support structure for mounting fire-resistant glazing in vertical, diagonal and horizontal building systems. To improve such a support structure so that the demands laid down in the required standards are satisfied for a fire-resistant period of at least 30 min, the invention proposes that the holding profiles (6, 7) be made as rectangular closed hollow profiles having, on the two narrow sides, a C-shaped channel, between which profiles the fire-resistant glazing, which is made as a laminated glass unit, is fitted via ceramic fibre layers (15, 15', 16, 16') which lie against said glazing, that a seal (10, 10', 11, 11') which covers the ceramic fibre layers (15, 15', 16, 16') is arranged in each of the C-shaped channels of the holding profiles (6, 7), that the inner holding profile (6) is provided with a plurality of mutually spaced openings (20, 21, 22) on that portion of its side facing the laminated glass unit which lies in the glass rebate space (19), and at least in one longitudinal side accommodating the seal in the region of the bottom of the C-shaped channel, that the hollow profiles (2, 3, 3') forming the metal frame have an outwardly directed nose-shaped projection (5) which forms a stopping face for the inner holding profile (6), and that the outer holding profile (7) is sealed (24) towards the outside in the fixing region.
