Abstract:
A large, preferably transportable container which can be closed by a refractory sliding door consisting of a plurality of sliding leaves has a problem zone through which heat from a fire outside the container can enter the large container in the upper cover region in which runner rails for guiding rollers connected to the sliding leaves are mounted. The invention optimizes the fire resistance. To this end, a fireproof partition (10) arranged parallel to the sliding leaves (1, 2) is fixed to the cover (8) of the large container (7) across the whole width of the sliding door and projects into the space between the sliding leaves (1, 2). The fireproof partition (10) and the sliding leaves (1, 2) are provided with a layer of insulating elements (14) on the sides facing each other in the region of overlap. As a result, flames are prevented from entering the container directly through this region, and space between the sliding leaves and the fireproof partition (10) is closed by the layer of insulating elements to form an air lock.
Abstract:
The object of the invention is to produce fireproof doors having two door panels (1 and 6) spaced from each other and having rectangular support inserts or bracing partitions (7-9) arranged between them. Rectangular blanks are used for the support inserts (7-9) and the edges to be brought into abutment with the inner sides of the door panels (1 and 6) are provided with transversely outwardly directed protrusions (11 and 12). The blanks (7-9) are placed between the two door panels (1 and 6) so that the latter abut the protrusions (11 and 12) and are perpendicular thereto. With the help of welding jaws (17 and 21) the two door panels (1 and 6) are pressed towards each other into abutment with the edges adjacent the protrusions (11 and 12), the protrusions (11 and 12) being simultaneously melted and thereafter solidifying to form binding welds (29 and 30).
Abstract:
Construction for separating two or more spaces, comprising: one or more frame parts (3) which are fixable to a wall part or to each other; a door part which is hingedly fixable to a frame part; one or more pane parts which are fixable in frame parts above and/or adjacently of the door part; and securing means (9) for holding the pane parts and/or the door part fixedly against the frame parts.
Abstract:
A fire-proofing glazing (1a) is composed of two panes (2) spaced apart by spacers (4, 6) and a fire-proofing foil (25) wound on a shaft (22) in the upper spacer (4). The fire-proofing foil (25) is secured with its outer longitudinal marginal zone (27) to a plate-like traction weight (28). The traction weight (28) is fixed in position in the upper spacer (4) by means of a meltable positioning material (31). In the event of a fire, and once the positioning material (31) has melted, the traction weight (28) filled with a drying agent (20) is pulled downwards by the force of gravity and unwinds the fire-proofing foil (25), which thus forms between the panes (2) a shield that is inflated when a determined temperature is reached. Instead of the wound fire-proofing foil (25), a folded fire-proofing foil may also be used.
Abstract:
In order to allow a fire door to close despite the presence of an obstruction, e.g. a fire hose passing through the door opening, the invention provides a door assembly comprising a first panel member (1) which constitutes the major portion of the assembly, and a second panel member (2) which is pivotally connected to the first panel member. The pivot axis for the second member extending across substantially the entire width of the first panel member. Pivoting of the second member allows the door assembly to close despite the presence of the obstruction.
Abstract:
A hermetically closing safety door capable of opening in two directions, in particular a fire-retarding door for cable rooms, has a door surface suspended from the door frame by means of hinges that ensure a three-point suspension. A hand-operated lock arranged on the door frame locks the door surface, heat insulating material is incorporated into the door surface and the gap between the door frame and the door surface is sealed. The disclosed door has two leaves (2, 3) that open in opposite directions. The larger leaf (2) is suspended by means of hinges (5) from a door frame (1) built into the wall, whereas the smaller leaf (3) is fixed by hinges (5) to a frame (7) formed in the larger leaf (2). The leaves (2, 3) are secured to each other and to the door frame (1) by means of closure means (6) that can be closed by hand and the leaves (2, 3) are provided on their face opposite to their opening direction with sealing edges (4).
Abstract:
An openable multi-pane window of fire resistance class F 60 having a window frame (2) and mutually connected window sashes (4, 6, 8), in which a single pane of borosilicate-fire resistive glass (16) is fitted into a metallic outer sash (4) on the outward side of the window, and a two-pane sealed glazing unit (18) is fitted in an inner sash (8) on the inward side of the window. The window frame (2) and the inner window sash (8) are made of wood, and a metallic clamping frame (20) is fitted in the inner sash. The glazing unit (18) is clamped firmly along its edges in the metallic clamping frame by means of an adjustable clamping force effected through the medium of tightenable clamping screws (54). The glazing unit (18) includes a borosilicate-fire resistive glass (22) and a pane (24) of conventional window glass on the inward side of the glazing unit. The freely exposed surfaces of at least the wooden window frame (2) and the wooden inner sash (8) on the inside of the window are coated with a fire resistive paint. The invention also relates to a fixed multi-pane window construction in which a glazing unit is firmly clamped through the action of adjustable clamping pressure in a metallic clamping frame which is fixed to the window frame.
Abstract:
An intumescent seal comprises a first body or mass of intumescent material (3) which provides a hard foam on heating and a second body or mass (4) of intumescent material which produces a soft foam on heating. An intumescent seal comprises at least one body of intumescent material (3) which produces a hard foam on heating and at least one body of intumescent material (4) which produces a soft foam on heating, the intumescent materials (3, 4) being carried by at least one of a pair of members or parts between which gap (24) is defined at least in a predetermined relative position of the two members or parts, the intumescent material being disposed so as to intumesce into the gap (24) on heating at least when the members or parts are in said predetermined position.
Abstract:
A method for producing a high-resistance fire door presenting an integrated resistant construction is characterized in that a filler mass is cast together with the reinforcement frame of the door leaf required in a mould corresponding to the size of the door so as to obtain a plane surface as a single unit.
