Abstract

Brama jest wyposażona w parę ognioodpornych kurtyn (1, 2), które są zamocowane do dwóch poziomych wałów nawojowych (3, 4), ułożyskowanych z obu stron nadproża otworu (6) w ścianie budynku. Każda kurtyna (1, 2) składa się z dwóch usytuowanych obok siebie i wzajemnie zespolonych, elastycznych płaszczy wielowarstwowych (11, 12), a ponadto z umieszczonego w odstępie od nich elastycznego płaszcza jednowarstwowego (13), utworzonego z tkaniny ognioodpornej. Każdy płaszcz wielowarstwowy (11, 12) składa się z ognioodpornej warstwy nośnej, warstwy termoizolacyjnej oraz dwóch warstw odblaskowych. Wszystkie płaszcze (11, 12, 13) każdej z kurtyn (1, 2) są przyłączone do wspólnego wału nawojowego (3 lub 4). W dolnej części obudowy (8) wału nawojowego (3 lub 4) jest utworzona przestrzeń, która oddziela zespolone, wielowarstwowe płaszcze (11, 12) kurtyny (1, 2) od jej jednowarstwowego płaszcza (13). W przestrzeni tej znajduje się pozioma prowadnica płaszczy (11, 12, 13), która jest zamocowana wzdłuż wału nawojowego (3 lub 4).The gate is equipped with a pair of fireproof curtains (1, 2), which are attached to two horizontal winding shafts (3, 4), mounted on both sides of the opening lintel (6) in the building wall. Each curtain (1, 2) consists of two adjacent and mutually integrated, flexible multilayer coats (11, 12), and also a spaced flexible single-layer jacket (13), made of fireproof fabric. Each multi-layer coat (11, 12) consists of a fireproof load-bearing layer, a heat-insulating layer and two reflective layers. All coats (11, 12, 13) of each curtain (1, 2) are connected to a common winding shaft (3 or 4). In the lower part of the housing (8) of the winding shaft (3 or 4) a space is created that separates the composite, multi-layer coats (11, 12) of the curtain (1, 2) from its single-layer jacket (13). In this space there is a horizontal coat guide (11, 12, 13), which is attached along the winding shaft (3 or 4).
