Definitions

  • the invention relates to a smoke trap arrangement according to the preamble of claim 1.
  • Such known from the practice smoke skirt assemblies include a roller on which a smoke skirt is wound from flame retardant material, which is unwound in a fire alarm to separate parts of the building or to form smoke sections.
  • a bearing of the roller and its drive means are arranged substantially within the roller and led out for mounting partially from this side. Because of this lateral lead-out, the roller with its storage and with their drive means is difficult to assemble. In addition, the space required by the side of the roller for accommodating the led out of her parts is relatively large.
  • the present invention has for its object, while avoiding the disadvantages of the known smoke trap arrangement to train them so that it can be easily mounted and the side of the roller occupies little space.
  • the roller can be placed on the rollers in a simple assembly step. After completion of the assembly, the roller can be rotated by at least one of these rollers, which is driven by the drive means, to wind the smoke skirt.
  • the drive means are arranged externally next to the roller and therefore do not require any torque-transmitting connection means or a mounting space at the end faces of the roller.
  • the drive means may in particular be located below or on the longitudinal side of the roller. At its end faces, the roller is enclosed between two axial limits, which can be close to the end faces of the roller, can be flat and in particular consist of sheet metal.
  • roller and the rollers are particularly advantageous housed in two cladding parts made of sheet metal, as stated in claim 2.
  • the rollers are arranged, which receive the roller.
  • the second trim panel removed, which in the mounted state can close off the trim panel which is partially open on one longitudinal side, the roll can simply be laid onto the castors in the first trim panel or removed from these castors.
  • the rollers are offset from the frontal Axialbegrenzonne away towards the roller center, whereby the load and deflection of the roller can be kept low.
  • a gap is left in the bottom region between the first trim part and the second trim part mounted on it, to which the smoke skirt is guided and through which it passes downwards.
  • the parts arranged inside the first trim part include, in particular, the transverse plates on which the rollers are mounted and on which the drive means are mounted.
  • the cross plates have according to claim 3 preferably trough-shaped recesses, which allow an insertion of the roller on the rollers and removal of the roller from the rollers from above and laterally.
  • the transmission of torque from the drive means, in particular an electric geared motor to the roller takes place at this only by friction with the driven roller or the driven rollers.
  • the outer circumference of the roller expedient according to claim 4 has a knurling.
  • the first roller and the second roller preferably on a drive shaft which can be coupled to the drive means and which is mounted in two of the cross plates.
  • two only supporting rollers namely the third and the fourth roller on the roller respectively in substantially the same plane as the first driven roller and the second driven roller, and thus as the two driven rollers be axially offset in the longitudinal direction of the roller.
  • the roller is supported on both sides in two axially spaced peripheral regions in each case by a driven roller and a non-driven roller and it is achieved a particularly stable support and uniform power transmission.
  • the drive shaft is on the one hand, ie at one of its ends via a coupling with a geared motor in conjunction and on the other hand, ie at its other end, with a centrifugal brake.
  • a geared motor in conjunction
  • the roller can be reliably operated in a conventional manner: Normally, in the idle state, if there is no fire alarm, the smoke skirt largely wound on the roller. In this case, only a portion of the smoke skirt is guided through the slot between the trim parts to the outside and depends on the outside burdened by the force of a weight tube down. In this initial state, the roller is blocked by the geared motor.
  • the clutch In case of fire alarm, the clutch is opened, which can be done in an electromagnetic clutch simply by switching off a stream, and the smoke skirt rolls off under the force of the weight tube automatically to form a smoke section.
  • the centrifugal brake has the function of slowing down the smoke skirt over the roller, so there is no risk of injury during unwinding. - Only when the initial state of the smoke skirt assembly to be restored, the clutch closed and turned on the geared motor, which rotates the roller over the driven rollers, so that the roller winds the smoke skirt and thus pulls the outer end with the weight tube.
  • the drive shaft may be mounted at its first end at least in a third cross plate which is parallel to the first cross plate and is arranged adjacent to this. Furthermore, the drive shaft may be mounted at its second end at least in a fourth transverse plate, which is arranged parallel to the second transverse plate and adjacent thereto.
  • the first cross plate and the third cross plate thus form a stable group, which can be supplemented with a fifth, central cross plate, at one end of the drive shaft with a roller.
  • the second cross-plate, the fourth cross-plate, if necessary, with a sixth, central cross-plate a second group.
  • the transverse plates are arranged parallel to one another, forming clearances.
  • the roller for attachment of one end of the smoke skirt has a peripheral recess which extends parallel to a roll axis and is shaped so as to be suitable for receiving a receiving tube to which an inner end region of the smoke skirt is attached.
  • a clamping profile in which a reaching into the recess web, and at a distance to this two clamping tongues are formed between a first wall of the recess and one in the recess in the distance to the first wall shaped survey can be spread apart.
  • the clamping profile in the peripheral recess under pressure of the exception tube to the web and over this and the smoke skirt on a second wall of the peripheral recess, which is opposite to the first wall, are clamped.
  • the recess thus ensures, in conjunction with the clamping profile, that the inner end portion of the smoke skirt with the receiving tube can be easily attached to the outer circumference of the roller and still be held securely on the roller.
  • clamping tongues of the clamping profile can be spread apart by a dowel pressed or hammered in between the clamping tongues for reliable locking of the clamping profile and thus also of the receiving tube with the inner end region of the smoke skirt.
  • the outer circumference or the knurling of the roller is reduced by the thickness of the smoke skirt.
  • the roller and the clamping profile are made of aluminum. So that the smoke skirt assembly nevertheless satisfies legal requirements, and withstands sufficiently long high temperatures, which can not be reliably realized with aluminum, the receiving tube as the trim parts are made of steel. This ensures that the inner end portion of the smoke skirt with the receiving tube can not slip out of the gap between the two trim parts even when the clamping profile of the roller under extreme long-term exposure to heat dissolves.
  • 1 denotes a roller of a smoke skirt assembly, which is formed substantially as a hollow cylinder with internally shaped stiffening ribs 2, 3, 4. In opposing pairs of grooves, e.g. 5, 6, if necessary, further stiffening plates can be inserted.
  • a cylindrical outer periphery 7 of the roller 1 has a peripheral recess 8 which runs parallel to a central fictitious roller axis.
  • the roll axis is referred to as fictitious, because although the roll 1 can rotate about this axis, but the axis is not materialized and thus can not serve for the storage of the roller or its drive.
  • the peripheral recess 8 is provided for receiving a receiving tube 9 which is inserted through a closed inner end portion 10 of a smoke skirt 11 made of non-flammable material, see Figure 5.
  • the peripheral recess 8 can be closed by a clamping profile 12, whereby the cylindrical shape of the outer periphery 7 is largely completed.
  • rollers For the rotatable mounting of the roller 1 and to its drive to wind the smoke skirt, serves an arrangement of rollers in cross members, which are arranged in a first trim part 13 made of sheet metal.
  • FIG. 1 shows an outer transverse plate 14 and FIG. 4 shows, in addition to the transverse plate 14, further spaced transversal transverse plates 15, 16, 17, 18 and 19, whereby the transverse plates 14, 15, 16 on the one hand and 17, 18, 19 on the other hand each form a group in which they are arranged relatively close to each other at a mutual distance.
  • a first cross plate 14 and a third cross plate 16 are referred to as adjacent in this application, although there is still another fifth cross plate 15 between these two cross plates. The same applies to the transverse plates 17, 18, 19 of the second group.
  • transverse plates With respect to the roller 1, in particular their longitudinal extent, from Figure 4, from which it is also apparent that the groups transverse plates 14, 15, 16 and 17, 18, 19 not directly at the ends of Rollers 1, but at a distance to these are. All transverse plates have trough-shaped recesses in order to receive the roller 1, as shown in FIGS. 2, 3 and 4, wherein the roller 1 projects beyond the outer transverse plates 14, 19 on both sides.
  • the shape of a trough-shaped recess is shown specifically in FIG. 1 to the recess 20 of the transverse plate 14.
  • roller 1 To accommodate the roller 1, to its rotatable mounting and to its drive serve the above-mentioned rollers which are mounted on the cross plates.
  • the other rollers, for example 24, as well as the rollers 21 and 22 between the cross plates 15, 16 and 17, 18 may be arranged.
  • the seated on the drive shaft 23 rollers 21, 22 may be referred to as drive rollers and the other rollers, which are not driven, as support rollers.
  • the roller 1 can be stably placed on the rollers so that they can rotate in the position shown in Figure 2 on the rollers and together with these, without being pulled out of this position by the smoke skirt 11 ,
  • roller 1 also reliably retains its axial position during rotation and possibly not quite uniform loading
  • axial limitations 25, 26 are provided in the form of metal sheets, see FIGS. 3 and 4.
  • roller 1 To drive the inserted into the transverse plates 14 to 19 roller 1 to wind the smoke skirt 11, serves a geared motor 27 which is mounted on the cross plate 14 and is connected via a coupling 28 to the drive shaft 23 in torque transmitting connection.
  • a centrifugal brake 29 is mounted on the outer cross plate 19, which is also connected to transmit torque to the drive shaft 23. With the centrifugal brake 29, the roller 1 can be braked automatically when the smoke skirt 11 is deducted too quickly at fire alarm after opening the clutch 21 under the force of a weight tube 30 at an outer end 31 of the smoke apron.
  • the gear motor 27 is, as far as it is not self-locking, provided with a brake 27a.
  • a protrusion 32 is formed between the first wall 33 of the recess and a second wall 34 of the recess arranged opposite the recess 8.
  • the clamping profile 1 which virtually completes the outer circumference 7 of the roller 1 in the region of the recess 8 and closes the recess 8, has an inner web 35 which is adjacent to the second wall 34 of the recess and at a distance from the web 35 two clamping tongues 36, 37, which are conically shaped in its lower portion and are adapted to engage in recesses 38, 39 of the first wall 33 and the elevation 32 when the clamping tongues are spread apart.
  • shell-shaped depressions 40, 41 are formed, which are adapted to receive a cylindrical dowel pin between them, which spreads the clamping tongues 36, 37 apart.
  • the smoke flap arrangement is held on carrier profiles 46, 47, to which in particular the transverse plates 14 to 19 can be attached.
  • the roller 1 can be placed on the rollers and the smoke dam assembly can be completed by the first trim part 13, the axial boundaries 25, 26 and the second trim part 45.
