Abstract

A structure of corners (4) comprising: three groups of direct expansion modulated frames forming a metal structure (4) providing through fixing elements and with oblong holes for assemblies (5, 6, 7, 8, 24) an individual expansion of each modulated frame (1, 2, 3) forming the floor bearing structure comprised of two glazing groups (12, 14, 15), the first of these two glazing groups having a flame-arrester function. The second glass group bears important loads, resting on an isolated panel (13) which is used for the perfect holding of the first glazing group and also has a thermal barrier between the two glaze groups. The low portions of this structure are isolated by means of a folded steel hood and isolated by alumina silica threads. The assembly is fixed to masonry walls through the oblongs holes by means of an assembly of fixing elements which provide for its holding and dilatory displacement.

Description

PLI.CAN R FILAN7 VI7RE FIRE STOP 120 INU7ES:

  The invention conceives three & gnoups of modulated chdasis with independent expansion of the type of a glazed planchen making it cut / had long dur ef nr-zs long dune for the purpose of pnotection

  fires in high-risk premises.

  There is currently no ptanchen vuitné coupe- / eu.

  Alai there are paneflamme planchern of a design and

  of a completely different use of the óut sought to obtain.

  Pan-flame protection is considered insufficient

  pan the fire safety services.

  In fact, a 6 mm thick annealed varnish was held laterally by two overhanging corner pieces, one for the protection of the four-flame flame from falling from the shelter, or to the other during the fire, of datle.s of verne being able to support weights in prolonged parking before the fire. Experience has shown that this type of design is unknowing / fisanL and inesLhetic. No overturning hood is planned. In the event of a fire, the vnnee panel for the use of planchen 3rd deflates in pnotubénance blows the fire, breaks and falls under the ca eoi, re.ste in heaps, this.reventing its function of planchen. Inner air can in this way continue to function as a panel during a week. In addition, Lige. from fixa.ion

  25. Rigidly solidify the chassis placed on the masonry.

  No diltataion is possible. The structure of the plank is deflected sideways, accentuating the creep posaiBility of the paraffin flap panel which ends up falling at the end of an hour. In addition, the longitudinal and / or lateral extension of the chdssi- is not pOs3sibe. It must be incorporated

  one or two btfon beams with two or more boards.

  This or these beams go against the aesthetic research of the architect due to the fact that they limit the "transpatency" of the floor, zealously forming light wells. The vetier volumes inside the carrier profile of the board are of considerably smaller dimensions. To go from a fireproof board to a fireproof board, the technique is different and according to this embodiment, it would greatly widen the thickness of the potty chdssi and put a glass of different design, tee , thick and comprising several transparent multilayer sales panels provided with intumescent interlayer repeats representing thermal banners, insulating at temperatures of more than 1,000 degbeis, with a view to protecting the monolayer or multilayer veane supposing a certain mobile weight or in prolonged or permanent parking and this, at f / oid or during the fire and this, duaant a cost, long or t / t long duration, which is impossible with a glass paeflamme pe / putting the tadiation of the integrated heat of the fire and preventing only, its fnanchement pan of the flames. The zdle of a flame-retardant glass is incomparable with fire-resistant glass. Fireproof sales are pan-flame at the same time, but pan-flame glass is in no way fire-resistant. The / adiation of the heat by the pan / flame, is always done from the start of the fire, while the fire-resistant vearne ceases to be it only from 180 degrees oLtenu. sun la, surface not exposed to fire. It is not possible to park on a flame-retardant board during the fire. The.s 3 groups of modulated chassis with independent expansion composing this vitLed plank cut- / had according to the invention has for patllie these drawbacks ef to wind up in the cut cut- / had more than two hours, thus allowing the
