Abstract:
A surface mounted fire and smoke seal comprises a plastics mounting strip (1) which is turned through a right angle along one of its sides to define an upstanding wall (2). A first relatively flexible plastics strip (3) extends downwardly from the upper margin of the wall and is inclined towards the mounting strip at an angle approximating to 45 DEG to the wall. A second relatively flexible plastics strip (4) is attached to the floor of the mounting strip and is inclined upwardly therefrom at an angle approximating to 45 DEG thereto. The two flexible strips lie in substantially the same plane with a spacing between their free edges or with their free edges in contact.
Abstract:
The flame-arrester glazed running walls are comprised of a mixed structure comprising an assembly of metal sections (10, 11) separated by intercalary elements (2) made of isolated material, dismountable panels (3, 23) for holding a glazing group on one side; an external hood (9) internally covered with a band (1) of adhered isolating material, and other dismantable panels (3, 23) on the other side, conformed to the four sides of a pre-frame which provides both for the firm holding to the concrete walls and the free expansion of the running wall (7) on three sides, the pre-frame itself being provided with its expansion system so as to provide for the construction without limits in the vertical direction and longitudinally by juxtaposing frames forming the running wall in the height and length directions, are set in place cold and which expand when they are hot, and which are not rigidly fixed.
Abstract:
A fire window comprises a panel of Georgian wired glass suspended within a frame by suspension pins extending through holes drilled in the glass so that each pin lies within a complete mesh. When the panel is subject to the intense heat of a fire, the glass softens and sags, but remains suspended within the frame by means of the interaction between the wire mesh and the suspension pins.
Abstract:
Battant résistant au feu destiné à être utilisé dans un montage de porte de cloison marine étanche de classe "A" comprenant un noyau pris en sandwich entre deux panneaux. Le noyau est constitué par une membrane en acier ondulé (11) tandis que chacun des deux panneaux est une plaque rigide préformée (12) en ciment renforcé par des fibres. Un interstice d'air (14) est créé entre les panneaux (12) par le noyau ondulé (11). Un canal de chapeau (13) à section en U s'étend autour de la périphérie du battant et est assemblé à onglet au coin et soudé de manière à former un châssis rigide renfermant les panneaux (12) et la membrane de noyau ondulé (11). La membrane (11) est soudée par point au rail de sommet et de fond du canal de chapeau (13), et les panneaux (12) sont collés sur les ondulations respectives de la membrane (11). La région de noyau confère ainsi au battant sa rigidité principale contre la flexion et les panneaux extérieurs lui confèrent sa résistance à la chaleur.
Abstract:
Bei einer Brandschutzverglasung nach DIN 4102, die aus einem metallischen, Holz- oder silikatischen Rahmen (6) mit Glashalteleisten (7) und mindestens einer transparenten, ho mogenen, armierten oder Verbund-Scheibe, als Einzel- oder Mehrscheibenverglasung, aus Glas oder Glaskeramik sowie dazugehörigen Dichtungen (5) bzw. Vorlegebändern besteht, wird ein bei Einsetzen des Brandes, vorzugsweise etwas zeit verzögert, sich ausdehnendes Mittel derart zwischen Scheibe und Rahmenteil angeordnet, daß sich ein hinreichend hoher Druck zwischen Scheibenrand und Rahmenteil senkrecht zur Scheibenfläche derart aufbaut, daß ohne zusätzliche Verbie gung des Scheibenrandes auch bei hohen Temperaturen bzw. nach langen Feuerwiderstandszeiten eine Anpressung des Randes der Scheibe (2) im Rahmen (6) sichergestellt wird. Als sich ausdehnende Mittel werden Intumeszenzbaustoffe (1), Federn, Bimetallstreifen oder Systeme mit Gasfüllung verwen det.
Abstract:
The invention relates to a structural closure (19) consisting of a casement (2) and at least one wing which can pivot in the casement (2), having a frame in which is fitted a fireproof glass pane (15) or the like, in which the casement (2) and/or the frame consists of two aluminium sections (4, 5; 9, 10) secured together with the interposition of the fireproof glass pane (15) or the like. Despite the use of light metal, e.g. aluminium or the like, adequate temporary fire-resistance in the event of a fire in a structural closure (1) also having a bulkhead is obtained in that fireproof panels (6, 16) are fitted between the aluminium sections (4, 5; 9, 10) of the casement (2) and the frame and between the casement (2) and the wings, and between the frame and the fireproof glass pane (15) or the like fitted in the frame, there are components (21) which expand on heating which, on being heated, form a fireproof bridge between the fireproof components.
