Definitions

  • the invention relates to an automatic fire protection closure for automatically closing openings in walls and / or ceilings of fire compartment separations having transport rails, in particular for rooms connected by transport rails, according to the preamble of the main claim.
  • fire protection closures are arranged at the relevant points, which should automatically, safely and immediately close the opening due to use in the event of a fire. Furthermore, these "fire protection closures” should at least correspond to the fire resistance duration of the wall and / or ceiling in which they are used.
  • a device for sealing and closing fire protection closures for openings in a wall or ceiling in which a trap door or trap door is provided, which is held in a state of rest by a holding magnet .
  • a transport rail section bridging the opening is also held in its operating position by holding magnets.
  • the holding magnets are de-energized and the drop flap falls in front of the opening while the section is lowered into a designated shaft.
  • This known device is disadvantageous in that, due to its construction, it does not securely close the fire compartment in the event of a fire.
  • the construction is relatively space-consuming, since additional space must be available both for the drop flap and for the section of the rail to be moved.
  • the drop flap and the section can also be unintentionally released from the holding magnets by vibrations or the like.
  • DE-A-S 3 004 064 has a device which is similar in function, the section of the rail to be displaced being coupled to the drop flap via a guide, so that the displacement movement is carried out jointly by both parts.
  • the invention has for its object to provide an automatic fire protection closure that securely closes the fire section over a longer period of time in the event of a fire, whereby a small space requirement should be necessary for its construction around the opening to be closed.
  • a fire protection closure is made available for use with rail-bound transport systems, with which openings in fire compartment partitions can be sealed and closed with reliability, in accordance with the regulations for standards-compliant constructions, which is easy and safe to transport , in which the assembly process is uncomplicated and safe, the regular functional checks are easy to carry out, requires little maintenance, has sufficient mechanical strength so that the number of movements caused by transport operations is also achieved with a motorized drive, with a precise end position of the movable sealing element in the closed state is guaranteed.
  • an emergency closing device which ensures a mechanical closing of the opening from any position, in particular intermediate position, of the movable sealing element, even in the event of a power failure and simultaneous fire, and which requires little space around the opening.
  • the invention can advantageously be used for almost any type of transport system and can be used both horizontally and vertically.
  • the invention essentially consists of the outer surrounding frame 13, the slide 18, which can be moved parallel to the fire section partition 11, and the sealing element 22, which can be pivoted through 90 °, and the connecting unit 47.
  • FIG. 1 also shows that the mass balance 45 is connected to the slider 18 via deflection rollers 44 and a roller chain 43.
  • the roller chain 43 and the connections to the Mgssenaus GmbH 45 and the slide 18 are dimensioned so that the full weight of the mass to be balanced can be absorbed over the entire period of the fire even under direct fire.
  • the mass balance 45 is additionally accommodated in a protective tube, which, however, does not have to perform a fire protection task, is only attached for the purpose of accident prevention measures.
  • the sealing element 22 is connected to the axis 19 by means of strong hinges 27 and can thus be pivoted in a bearing via the pivot point 20 into the pivoting region 21.
  • the bevel gear 37 is attached to the underside of the axis 19 and represents the connection to the drive unit 23 via the second bevel gear. A positively guided connection to the slider 18 is thus established via the drive lever I 35 via the drive unit 23 by means of the run-off roller 34 and the guide rail 33.
  • the pivotable sealing element 22 acts as a drive for the lifting movement 17, 30 of the slide 18.
  • the intermediate frame 18 can also act as a drive for the pivoting movement 21 of the sealing element 22.
  • the drive device 59 and the connecting unit 47 up to the drive lever II 46 are omitted.
  • the closing process is thus carried out by the energy-storing door closer 38, which is mechanically connected to the sealing element 22.
  • the sealing element 22 In the open position, the sealing element 22 is held in place by a non-illustrated holding magnet of the fire monitoring system.
  • the hat magnet In the event of a fire alarm, the hat magnet is de-energized and releases the sealing element 22, as a result of which the door closer 38 comes into effect.
  • the locking is carried out via the locking bolt 65.
  • the door handle 73 is actuated by hand, as a result of which the locking bolts 65 are unlocked.
  • the slide 18 With each opening and closing movement, the slide 18 carries out the lifting movement with the dimension i with the screwed-on section of the transport rail 12.
  • the stroke movement i depends on the length of the drive lever I 35 and its swivel path 40.
  • the door closer 38 is omitted at this point and all movements are carried out by the drive device (FIG. 6) 59. Furthermore, the door handle 73 is omitted and the locking or unlocking of the sealing element 22 via the locking bolts 65 is carried out by means of the lifting rod 66, which is actuated by the cam disk 64.
  • Fig. 1a shows the fire protection closure as explained in the description of Fig. 1, but in a modified form.
  • the drive lever I 35 is attached to the continuous shaft 84, which in turn is rotatably supported in the bearing block 83.
  • the drive lever III 87 is fastened on the continuous shaft 84.
