Definitions

  • the invention relates to a smoke protection closure for the smoke-tight sealing of openings in walls and / or ceilings, in particular for rooms connected by transport rails, with a slide that can be moved parallel to the wall or ceiling.
  • Fire barriers for closing openings in fire compartment partitions are generally known. In rooms connected to transport rails, either a piece of the transport rail is removed from the displacement path of a slide or there is a gap in the transport route from the outset, so that a slide can be pushed in front of the opening in the event of a fire, resulting in a fire-proof closure.
  • Such fire protection closures must be in accordance with the existing Regulations are not smoke-tight. However, it has been shown that the smoke that arises in front of the actual fire or smoke that arises during the fire has a strong influence on the fire situation.
  • the invention is therefore based on the object of providing a smoke protection closure according to the preamble of the main claim which closes smoke-tight openings at least up to a temperature of 200 ° C.
  • a slide is provided which is guided in slide guides, each slide guide consisting of a metal profile and a slide bar which can be displaced relative to one another.
  • the sliding bar is made of a plastic that swells at an elevated temperature so that the flue gases, which can reach a temperature of 200 ° C and above, cannot pass through the opening.
  • a limit value for the passage of smoke of 10 standard m3 of flue gas at 50 Pa is specified, with the present invention this limit value is far below.
  • the sliding guide thus has two functions; it also serves as a bearing for the slide itself and as a smoke seal. It is also particularly advantageous that the plastic regresses when it cools down, so that the smoke protection cover can be opened again after the temperature has dropped.
  • the smoke protection cover has a frame 1, for example made of sheet steel, which is fastened to the wall or ceiling 4 having the opening 3 by means of fastening angles 2.
  • a slide 6 is guided in the steel frame by means of slide guides 5 and is open in the normal operating state.
  • Transport rails which can be arranged transversely or perpendicular to the closing direction of the slide 6 lead through the opening 3.
  • a gap 8 is provided in the transport rails 7, through which the slide blade 6 extends.
  • the transportation rails should also be designed such that they have a removable piece in the displacement of the slide 6, which is removed from its displacement with the movement of the slide 6.
  • a drive unit which has a drive motor 9, a gear 10 and a slip clutch 11.
  • the motor 9 drives a drive lever 12 via the transmission 10 and the clutch 11, the end of which is firmly connected to a run-off roller 13 which runs in a guide rail 15 fastened to the slide 6.
  • the open position of the slide 6 is indicated by the dashed lines, the pivoting movement of the drive lever 12 being represented by the dashed semicircle.
  • a support 16 is provided to support the drive unit.
  • Fig. 4 is an enlarged view of a section through the sliding guide 5, which guide the slide 6 according to Fig. 1 above and below.
  • the sliding guide consists of a first metal profile 17 which is U-shaped and which is connected to the mounting brackets 2.
  • a second metal profile 19 with a C-shaped cross section is fastened to the first metal profile 17 by screws along the frame 1.
  • the slider 6 is also connected by screws 20 at the upper and lower ends to a sliding bar 21 which is adapted to the profile of the second metal profile 19, that is to say it has a substantially rectangular cross section and is provided with lateral incisions into which the legs 22 of the C-profile and guide the sliding bar.
  • the sliding bar is freely displaceable in the metal profile 19, the slider 6 nevertheless being securely mounted.
  • the slide bar 21 is made of a plastic, for example a low-pressure polyethylene, which has the property of swelling at an elevated temperature. If increased temperatures occur due to a smoldering fire or the like, the plastic expands so that the space formed by abrasion and necessary for unimpeded displaceability is filled between the metal profile 19 and the sliding strip 21. Thus, the slide guide 5 is sealed so that no smoke can get between the slide 6 and slide guide 5. When the temperatures drop, the plastic of the sliding bar 21 reforms so that the slide 6 can be opened again.

  • the slide 6 is sealed, namely by rubber strips 23, 24, which are attached on the one hand to the left of the opening on a square tube 25 and on the other hand to the right of the opening 3 by means of a strip 26 and the fastening angles 2 are attached.
  • the slider 6 abuts the seal 24 on the right in the closed state and engages around the seal 23 on the left, as indicated by the slight angle of the slide 6.
