Definitions

  • the invention relates to a fire protection device for air ducts, air duct shafts and air duct ducts, in particular of air conditioning systems, according to the introductory part of patent claim 1.
  • the aim is to divide a building into individual fire sections in the area of the air ducts, etc. in the event of a fire, the fire dampers in the closed position preventing the passage of fire, heat and smoke gases.
  • the length of time that a fire damper must remain effective in the event of a fire is determined by building regulations. These regulations also require that the fire damper be installed within the opening in the wall.
  • the line section containing the fire damper has so far been installed directly in the wall and, if necessary, sealed by plastering or other measures for opening the wall. This makes maintenance more difficult and there is a risk that the line part will be damaged during the plastering and cladding work on the wall, so that leaks can occur or the function of the fire damper is impaired. Can repair work often only after the wall has been opened and the respective line section opened.
  • the wired thermal switch When converting, repairing or maintenance work, the wired thermal switch can be removed and it happens that a new correct installation with temperature sensors protruding into the monitoring area is omitted, although the respective thermal switch is displayed on the remote display as "responsive" so that the meaning of the monitoring carried out is not fulfilled.
  • the main object of the invention is to create a fire protection device in which installation and maintenance are considerably simplified and the operational safety is increased compared to the previous designs.
  • a partial object of the invention is to create a simple drive and actuating device which leads the fire damper safely into the closed position and secures it in the closed position. Another part of the task is to ensure that when using the thermal switches assigned to the fire dampers, that the responsive state can only be displayed on the remote display if the thermal switch is properly installed.
  • the lead-through points are fixed through the wall before the air line is installed, and the frame or installation sleeve can be fully installed and, if necessary, plastered.
  • the fire protection device forms an insert part for this frame or installation sleeve and can be removed with its insert parts both from the air duct and from the frame. Nevertheless, a significant part of the fire protection device can be installed in the wall for operation.
  • the accommodation of the drive device in the line section protruding from the frame makes it easier to accommodate remote control or manual control devices.
  • the fire damper itself is preferred Made of a highly fire-resistant, asbestos-free material and can have a metal border at the edge. For use in hospitals, etc., the fire-resistant material can be sandwiched between welded or soldered metal sheets to make cleaning easier or to prevent germs from attaching to the flap.
  • an adjustment range of the crank of approximately 180 ° can be provided, which can be limited by fixed stops.
  • the fire damper is pivoted by approximately 90 °. Stops prevent a further turning after the dead center of the crank in the closed position.
  • the flap can no longer be pivoted out of the closed position by directly acting forces on it, but only by turning the crank back into the open position.
  • Claim 5 provides a remote-controlled, external drive unit for the fire damper.
  • the training according to claim 6 provides additional security.
  • a remote-controlled return of the flap to the open position is prevented until the lock in the immediate area of the fire protection device is released by manual operation or a new fuse is inserted.
  • the measure ensures that in the event of a fire, the inadmissible opening of the fire damper via the remote control is prevented, for example in the event of a control error.
  • An embodiment according to claim 8 is preferred, but a separate actuation sensor, for example a microswitch, can also be provided as an assembly sensor.
  • a further embodiment can be found in claim 9.
  • the switch sensor which is adjusted in the event of improper installation, indicates the response of the switch on the remote display, so that a check is forcibly carried out and correct installation is carried out. It is particularly advantageous that the thermal switches can be installed like conventional switches without changing the conventional switch designs.
  • a built-in built-in frame 1 is provided, which is designed for the air duct having a rectangular cross section in the exemplary embodiment as a rectangular frame made of a C-profile, the light width of which is chosen so large that the End of an air line can be inserted from both sides with the interposition of a seal.
  • the fire protection device itself is accommodated in a line part 2 which forms a housing and has a section 3 which can be inserted into the frame 1 and a section 4 which remains outside the frame, the ends of the section 4 being reinforced by projecting flanges 5, 6.
  • the flange 5 forms a stop for the edge of the installation frame 1.
  • the end of an air line and the section 3 can be inserted into the frame 1 with the interposition of seals, whereby can provide screw connections to the frame or to the subsequent line section on the flanges 5, 6.
  • a fire damper 8 is pivotably mounted about a horizontal central axis 7 from the rest position shown in FIG. 1, releasing the line via the intermediate position according to FIG. 2 into the blocking position according to FIG. 3, the valve 8 also being fixed in the blocking position attached elastically compressible seals 9 cooperating, the line closes smoke and flame proof.
  • a crank mechanism which or the like on an axis 10 between the stops. 1 and 3 has rotatable crank 11, which acts on the fire damper 8 via a link 12 at a distance from the axis of rotation 7.
  • an external drive device for. B. an electromagnet, a pneumatic motor, which can be operated via remote control devices, but also a hand lever or a spring motor can be provided, the spring of the spring motor being tensioned in the position according to FIG. 1 and a temperature sensor holding the crank 11, e.g. B. with a fuse melting at low temperatures, releases the crank 11 when the set temperature is exceeded, so that the spring motor can turn the crank 11 into the position shown in FIG. 3.
  • the crank of the crank mechanism is formed by a disk sector 13 which, in the vicinity of the edge 14, has the articulation point 15 for the handlebar 12, which acts on a bearing sleeve 16 of the fire damper 8.
  • the sector 13 is rotatably mounted on an outer drive shaft 10 with a sleeve 17, wherein either a spring acting on the sector 13 and the shaft 10 can be provided which tends to turn the sector 13 in the closing direction and again provides a temperature sensor, which releases the sector 13 when the set temperature is exceeded or couples the shaft 10 to the hub 17 with only external actuation.
  • the front edge 18 of the window sector 13 forms a stop for the fire damper in the closed position and a spring-loaded pin 19, which presses against the flank of the window sector 13, engages behind the edge 14 , so that the fire damper 8 is locked in the closed position until this pin 19 is released.
  • an outer drive shaft 10 is again provided for the fire damper, which can be actuated via a servomotor.
  • a thermal switch 20 and a hand switch 21 are attached on the front wall 24 of the line section 4.
  • the thermal switch is connected to a remote display and actuator. 6 to 8, it has an actuating sensor 22 which can be pushed out of its housing by a positioning spring.
  • the inserted position of the 7 the "ready position” and the extended position according to FIG. 6 the "response position”.
  • the actuating sensor 22 is in its responsive position on a temperature sensor, in the embodiment of a bursting ball 23. In the operating position, the temperature sensor 23 is inserted through an opening 25 in the front wall 24.
  • the bursting ball 23 or the other temperature sensor is held by a component rigidly connected to the thermal switch 20 in the position in which the switching sensor 22 is in the "responsive position" (FIG. 2).
  • the bursting ball 23 forming the temperature sensor is held in a cage formed as a sheet metal part 26, which can be inserted through the opening 25 and has retainers made of bent tabs 27 which limit the depth of insertion of the cage 26 into the opening 25. With their outside, these retainers 27 also form stops for a holding plate 28 which can be fastened to the wall 24 outside the retainers 27 with the aid of sheet metal driving screws. At a distance of the switching path from the retainers 27, further, curved retainers 29 are attached to the cage 26, on the straight legs 30 of which the holding plate 28 is guided with through-slots. The holding plate 28 is held captive on the legs 30 between the stops 27, 29.
  • the temperature sensor 23 can hold the switching sensor 22 in the position corresponding to the "response position" according to FIG. 6.
  • the response of the thermal switch 20 is therefore shown on a display, in particular a remote display. 7 is the switching sensor 22 in the position ready for response.
  • the holding plate 28 takes the entire thermal switch 20 into the fastening position via a collar 31.
  • the remote display now shows the switch 20 as "ready to respond”. If the temperature sensor 23 responds in this position, i.e. the bursting ball 23 bursts in the exemplary embodiment, then the switching sensor 22 is again adjusted to the outside, the switch 20 responds and actuates the drive device of the shaft 10 itself or via a remote control device and thus the flap 8.
  • the response of the switch 20 is displayed on the remote display.
