Abstract

The subject of the present invention is a firestop valve device comprising a support frame (1) surrounding an internal space (1a) intended for the passage of a gaseous stream and at least one shut-off element, referred to as flap (2), able to move between a closed position that prevents the gaseous stream from passing and an open position that allows same to pass. It comprises a partition (3) closing the internal space (1a) and one or more openings (3a) formed in said partition to allow the gaseous stream to pass, the or each opening being able to be sealed closed by the insertion and close fitting housing therein of said or one of said flaps by means of an articulation system (4a, 4b) actuated, if appropriate via a linkage system, by an actuating system. Another subject of the invention is an assembly made up of at least two such devices mounted in series.

Abstract

The invention relates to a fire-stop wall partition device to be installed in a high-security building. Said device includes a wall partition (1) and an opening (2) intended to receive a pre-hung door. The partition (1) includes a framework (4, 5) consisting of a first series of metal transverse U channels (4), and a second series of metal transverse C channels (5), said channels being assembled therebetween such as to form an outer rectangular peripheral frame, defining the surface area of the partition (1), and an inner rectangular frame defining said opening (2) for receiving the pre-hung door. The vertical sides of said frames are formed by the metal C channels (5), and the horizontal sides thereof are formed by the metal U channels (4). Said partition (1) also includes at least two fire-stop panels suitable for covering, around said opening (2), each side of the plane containing said framework.

Abstract

The present invention relates to a fire-stopping and fire-smothering storage container housing an inner space for storing materials which is defined, relative to the outside space (2), by a plurality of sides (3a, 3b, 3c, 3d, 3e, 3f) and including at least one fire door assembly (4). The invention includes an essentially fire-stopping, airtight structure of walls (5, 5') forming, together with the door assembly (4) which is also airtight, each side of the container, a system for attaching and assembling said structure and the door assembly, air passages (9a, 9b) extending through said structure, and air-sealing gaskets (8) making it possible to make the air passages airtight, such as to make the container airtight enough to create an air-depriving effect in the inner storage space that rapidly smothers any fire that starts inside of same.

Abstract

The subject of the present invention is a fire stop flap valve system with sealing comprising a cage (1) in the form of a square or rectangular surround comprising two first opposed internal faces (1a) and two second opposed internal faces (1b) which are perpendicular to said first internal faces, said cage (1) within its internal space housing a flap (2) or, as appropriate, a row of a plurality of flaps (2) which are square or rectangular and pivot mounted on said second internal faces. The cage further comprises two first plates (3a) each extending across one of the second internal faces and the or each flap comprises two second plates (4a) each extending along one of the sides and able to collaborate, when the system is in the closed state, with one of said first plates or, as appropriate, one of the second plates of an adjacent flap, the purpose of this being to provide enhanced and durable sealing of the system in the closed state.

Abstract

The subject matter of the present invention is a safety valve and anti-radiation device comprising a safety valve (1) and an anti-radiation partitioning or opening and closing member (2) comprising a main structure made from radiation shielding material (3) extending between the opposing faces (2a) or (2b) of said member and a fluid passage cavity (4) closed by said valve and traversing the member, emerging on each opposing face by means of an opening (4a) or (4b). The device comprises at least one shield (5a) or (5b) fixed to one or the other of said opposing faces, comprising an additional or complementary structure made from radiation shielding material (3') or (3") covering one of said openings in such a way as to stop or block any radiation likely to cross the cavity and/or the member while allowing the passage of a fluid under overpressure into said cavity with a view to allowing it to be discharged.

Abstract

The subject of the present invention is a watertight fire door for closing an opening in a building or edifice comprising, on the one hand, a fixed frame (1) and at least one opening leaf (2) and, on the other hand, sealing means (16, 17) that provide sealing between the fixed frame (1) and the opening leaf (2) when the door is closed. The or each opening leaf (2) comprises, on the one hand, a framework (3, 4) surrounding an empty space capable of accepting or forming a thermal insulator (7) and being sandwiched between two layers (5) and (6) of thermal insulation each essentially produced from a material having low thermal conductivity or diffusivity and, on the other hand, if appropriate, at least one thermal break.

Abstract

The invention relates to a door that is impervious, essentially to a liquid fluid and/or a gaseous fluid, and intended in particular to be installed in a high-security building, such as a nuclear power plant. The invention comprises a frame structure (1) of the fixed frame type, which extends substantially vertically when mounted; and at least one door leaf (2) which is in sealing contact with the frame structure (1) when the door is closed. The door leaf or leaves (2) comprise at least one sealed opening system (3, 4, 5) preferably in the lower part thereof, which can open automatically in response to a threshold fluid pressure being exerted on either the front or rear face of the corresponding leaf (2) at said opening system (3, 4, 5) and forcing the opening of the system, so as to allow the fluid to pass through the leaf or leaves (2).
