METHOD FOR MOUNTING FIRE AND FIRE SHIELD REGISTRY IN FENCE WITH FIRE AND SMOKE REGISTRATION IN A PARTITION, AND CUTTING REGISTER

FIRE AND SMOKE CUTTER

The invention relates to a method of assembling fire and smoke from a fire damper in a wall, and a fire damper and smoke damper.

The inconvenience and difficulty of mounting is a problem with existing fire stop systems or fire and smoke dampers. Correct installation is necessary for the proper functioning of a fire damper, and the risk of fire and smoke generation caused by a failed / faulty mounting is now a real problem. Almost all ways of mounting fire dampers require sealing of the fire damper wall seal on both sides of the firewall, which in practice is often impracticable under the conditions of a building site. In addition, especially with fire dampers to be mounted in a wall surface and equipped with a solid box, it is almost impossible to make a correct installation in the conditions of a building site, because the box prevents visibility in the through hole and thus increases the risk of misuse.

An additional problem posed by fire dampers with a solid box is their heaviness, which incurs additional costs during their handling and greatly complicates the mounting of the equipment.

The idea of the present invention has been to combine in the structure of the equipment a light integrated mounting flange, by means of which the fire damper can be easily mounted in a fire wall. This is achieved in the sense that the mounting flange of the equipment serves as a casting frame for the solid box. The casting of the mass can be done on the spot. At the same time, the cast portion serves as the firewall seal of the register wall flute at the mounting side, and no further operation is required to effect sealing or assembly. Preferably, the mass to be used is a so-called plaster-based mass, which is fluid during casting, but will harden after casting. The mass mi is a thermally insulating mass and stopping the fire.

The mass mi serves as a fire protection because it is a thermally insulating mass. It is placed close to the firewall and prevents fire and smoke from spreading from the Fire Safety Ground interface and the firewall. It also serves as a construction element giving stability to the construction, as it hardens after being poured into the casting space of the frame.

According to the invention, a flexible seal and a gasket which expands with heat are used. According to the invention, the flexible seal is installed so as to be the outermost all around, thanks to which it is fixed at its edges to the edges of the closure valve. The swelling of the seal under the effect of heat takes place under the flexible seal. In case of fire, the flexible gasket will prevent the smoke from spreading before the swelling seal expands under the effect of heat. As the temperature rises, the inflating seal will compress the soft seal against its opposite surface and prevent fire and smoke from spreading past the closure valve.

In addition, it has been possible to mount a swelling sealing tape under the effect of heat around the box of the closure valve, such as a conduit, in the through opening of the wall. The purpose of this is to serve as an additional seal in case of fire if the heat increases in the mounting opening.

In a modular arrangement, mounting frames can also be mounted one above the other and parallel, whereby fire dampers and thus air ducts can be mounted much closer to one another than does not allow the prior art.

The invention therefore relates to a fire damper and smoke damper, characterized in that the fire damper comprises: a) a casting frame, b) a rotary closure valve around which there is a box portion or a tube, and in that the box portion or the tube is placed through a through opening in the bottom of the casting frame.

According to particular embodiments, the register may comprise one or other of the following characteristics: the casting frame comprises a bottom and side walls which include a space for a mass, which is a thermally insulating mass, and in that fastening screws extend through a wall of the bottom of the casting frame by attaching to a fire wall, to which the casting frame is attached, and in that the mass is a thermally insulating mass or stopping the fire, which is fluid during casting and hardens after casting; an inflatable seal is located around the portion of the casing and is placed in a through opening of the firewall and will fill a space between the casing and the inner surface of the hole of the through opening when inflate in case of fire; - The fire damper and smoke damper has openings in the bottom of the casting frame through which the mass can be brought into contact with a wall surface to seal the gap between the frame and the wall. wall with mass; the walls of the frame preferably have a thickness of the order of 1 mm or less, and the height or the maximum width of the frame is of the order of 50 mm to 250 mm, measured on the duct, and in that the frame has a rectangular or square section, and preferably the depth of the frame is less than 100 mm; - opposite the bottom of the frame, the frame has a free opening, through which the space can be filled with a mass, and the space is limited by a bottom and side walls, and in that the frame has a rectangular or square section; the section of the duct is circular and, correspondingly, the section of the closing flap is circular, and in that the closure flap comprises on its periphery a seal which will swell under the effect of heat and, in case fire, will lock the fire damper in the closed position and close the casing, duct, tube or equivalent; - The seal on the circumference of the fire damper and flare damper is surrounded by a flexible gasket, the latter seal having a sealing portion placed on the periphery of the closure valve between its edges, and in that since the portion of the seal projects at least one lip of the seal, and in that the edges of the seal are placed against lateral surfaces of the body of the closure valve.

The invention offers the following advantages: - the invention allows a tight fitting of the fire damper in the structure, from a single face in the fire wall, by means of screws and by means of a posterior casting ; - the opening in the wall, necessary for the assembly, is the smallest possible, because no posterior casting is carried out in the opening of the wall; - it is easy to check that the assembly is correct. A fully cast / poured mounting / casting frame ensures proper mounting; - The fire damper is light during its transport and its assembly, because the casting is done only on the building site. The assembly time is shorter and the necessary labor is less than when using conventional modes of implementation.

Fig. IA is an axonometric view of a fire and smoke damper register 10, ie a fire damper, according to the invention. Fig. IB represents the fire and smoke damper 10 seen in the direction of the arrow Ki of FIG. IA. In the rest of the text, the fire damper and smoke damper 10 is also called fire damper.

The fire damper 10 according to the invention preferably comprises a casting circumference or casting frame 11 or frame 11 with a rectangular or square section, which casting frame comprises a bottom or a bottom wall 1 las and side walls liai , lla2, lla3 and lla4.

The casting frame 11 has an opening E in the bottom llasllai, preferably an opening E of circular section for a duct 12, or a box, which has inside it a closure valve or closure damper 13.

The closure valve 13 operates automatically by means of a thermal fuse, whereby, in case of fire, the closure valve 13 is released and a spring returns the closure valve 13 to a closed position. the duct portion 12, or the closure valve 13 may be remotely controlled and may include a rotation motor M. The axis of rotation is designated by D. In this way, in case of fire, the engine is started and the closing valve 13 is closed automatically by remote control.

The bottom lias, the side walls liai, lla2, lla3 and liai and the flanges R of the casting frame 11 define between them a casting space A for a mass mi. On the opposite side to the bottom lla5, the structure opens into the surrounding space from space A.

Preferably, the thickness of the sheet used for the frame is 1 mm or less. The frame 11a has walls of a thickness preferably of the order of 1 mm or less, and the height or the maximum width of the frame is 50 mm to 250 mm, measured on the duct, or on the cross section of the duct on its diameter.

Preferably, the depth of the frame 11 is less than 100 mm. With the aid of screws, the frame 11 and the box or the tube or the corresponding conduit 12 as well as the closure valve 13 are screwed and fixed to the wall S.

Through an opening D) of the wall S is put in place a portion 12a which protrudes from the frame 11 of the duct 12. Over and around the portion 12a of the duct 12 is placed a sealing tape known in itself and consisting of a swelling material, which sealing tape, in case of fire, fills a space between the portion 12a of the conduit and an inner wall Di of the opening of the wall S and prevents the spread of fire and smoke .

The bottom 1 las of the casting frame 11 comprises openings ei, β2, β3, e4 ..., by which the casting mass mj coming from the space A comes against a wall surface S, whereby the assembly of the structure with the wall S is made solid, which is necessary with regard to safety in case of fire.

The placing of the mass mj in the space A preferably takes place at the mounting location of the fire damper 10 in the wall.

Preferably, a hardening heat-insulating mass mj, based on plaster, is employed in the space A. The fire damper 10 comprises, opposite the bottom 1 of the frame 11, a free opening A to through which the space A can be filled with the thermal insulation mass mj. The space A is bounded by the sheet-shaped base and the side walls 11a, 11a, 11a and 11a in the form of sheets. The sheet-like side walls 11a, 11a, 11a and 11a4 comprise flanges R which are perpendicular to the central axis of the duct 12. They retain the mass mid in the space A.

The structure according to the invention is advantageous as a fire damper structure, because its fixing remains cold since the screws are installed with their head inside the mass mi in the space A. The structure according to the invention is climbs safely from one side into the opening Di of the wall. The opening Dj of the wall is small, because we do not need what is called a separate back casting, but just an opening just a little larger than the diameter of the duct 12. Since the register cuts Fire is easy to assemble, it is also easy to control it; thus, it is easy to proceed to the final control of the assembly of the fire damper, because it is enough to control it on one side. The fire damper according to the invention is also lighter in comparison with prior art solutions, for example a solid stone fire damper structure.
