Abstract:
The invention relates to a fire barrier for buildings, especially a fire door or window (2), with a frame (1, 3) in the wing or case region of a metal section (5), especially steel, in the interior of which there is a fire resistant material, in which the metal section (5) takes the form of a tray, generally C-shaped in cross-section with facing shank sections (10), the end regions of which are bent mutually parallel in the section interior (6) on the inside of the central C-arm (8) bounding the gap (13) between the case (1) and the wing (3), between the end regions (11) of which and bearing against them there is a plate of fire resistant material (7), the longitudinal face of which bears on the central C-arm (8). An easily and economically assembled fire barrier is produced in that at least the shank sections (10) of the wing frame (3) have an engagement device (11') which is hook-shaped in cross-section into which brackets (23) with corresponding hook components can be clipped, with the ends of the brackets (23) away from the hook components bearing on a pane of glass.
Abstract:
A process for producing composite profile sections used in the manufacture of fire doors and partitions consists of applying two outer profile sections (2) on a preferably extruded middle profile (1). This process allows the connecting elements and fittings generally used for the manufacture of doors and windows to be used. The connecting parts (4, 4a, 4d, 4e, 4f, 4g, 4h, 4i, 4l, 4m) between the profile sections (1, 2) fullfil the connecting function, the function of interrupting thermal bridges and if necessary the function of retaining the heat-insulating and refractory filling material (7) injected under the form of a paste. In addition, said connecting parts confer the required dimensional stability to the profile section, during injection of the filling material as well as during its curing.
Abstract:
The invention relates to a glazing member 1 which is a unitary non-inflammable moulded resin member which with an identical one 1a is used to hold a pane of glass 2 in an aperture in a door 3, the members 1 and 1a being held in position by nails 6. There is a flexible resin edge member 5 which is formed from an identical resin to that of the members 1, 1a but with the addition of an additive such as a flexiliser to render the resin flexible. The members 1, 1a, pane 2 and door 3 form a fire containing system.
Abstract:
Disclosed is a fire door consisting of a functional set including at least one revolving door and a sliding door fixed thereto. The sliding door, which is designed for automatic horizontal move, comprises an auxiliary drive which in a danger situation sets the sliding door in an open position and at the same time the wing revolving door in the regulatory closed position.
Abstract:
A frame assembly comprising a non-combustible rigid filler sheet supported within a surrounding support frame, the support frame comprising lengths of a structural frame member joined together, the structural frame member including an elongate body extruded from a heat meltable material, the body including longitudinally extending cavities and intumescent material located in selected cavities.
Abstract:
A fire screen comprises a number of fire resistant glazing panels (5, 6) mounted in fixed frames (2, 3) and in opening frame (4). Each frame has first and second extruded alloy elements (7 and 8) respectively which are interconnected by insulating webs (9) to limit the conduction of heat from one side to the other. The hollow core of each frame member receives a number of bar lengths of monolithic calcium silicate to form an articulated insulating core which can help to maintain fire integrity when the frame distorts when exposed to fire. Intumescent seals are provided at the facet joints. The insulating bars (9) are profiled to engage channel formations on the alloy frame elements. In the event of the elements on one side melting in the fire, the bars remain attached to the surviving elements on the side remote from the fire and afford a measure of protection thereto.
Abstract:
The invention solves the question of the design of an expanding, fire-proof seal and gives a method of making of the expanding, fire-proof seal. The expanding seal consists of an expanding core ( 1 ) which, together with an elastic spacer ( 5 ) is placed in a protective jacket ( 2 ) having a form of a pipe of closed profile, made of thermoshrinkable plastic. A part of the outer surface of the wall of the protective jacket ( 2 ) is covered with an adhesive layer ( 3 ) which is covered with a protective strip ( 4 ). The expanding core ( 1 ), together with the elastic spacer ( 5 ) is inserted into the protective jacket ( 2 ) and then a part of the perimeter of the protective jacket ( 2 ) is thermally shrunk and the adhesive layer ( 3 ) and the protective strip ( 4 ) are applied on the shrunk part of the surface.
