Definitions

  • the invention relates to a smoke apron for sub-dividing and/or channelling smoke and fumes in and around buildings such as for example industrial structures, shopping centres and the like, particularly in the event of fire, and concerns such an apron having a housing to extend along a sub-dividing or channelling line, the housing supporting an apron sheet capable of being raised and lowered.
  • Smoke aprons of the aforementioned type are used in relatively large buildings such as shopping centres so that when smoke and fumes develop, for example in the event of a fire, it is possible to prevent the smoke and fumes spreading over extensive areas inside the building or - in the case of a covered structure, outside the interior of the building - to prevent too great a lateral spread of a rising column of smoke and fumes which would result in an undesired degree of smoke logging under the covered structure.
  • the smoke cools down on parts of the structure or fittings, resulting in a loss of thermal updraught. This gives rise to a circulating pattern of flow of smoke the smoke billowing within the confines of the building so that it is no longer possible for people to recognise escape and rescue routes; and toxic fumes can cause death from asphyxiation.
  • a smoke apron as described at the outset, with an apron sheet which is supported in a building in such a way that it can be rolled up, is known from GB-PS 22 108 839.
  • the apron which can be raised by an electric motor, is fitted into a housing formed by a suspended ceiling having a throughway.
  • a weight fitted along the lower edge of the apron closes off the ceiling gap which provides the throughway.
  • the apron is guided at its side edges in channels.
  • the object of the present invention is to provide a smoke apron as described at the outset which can be constructed in a structurally simple manner for the secure sub-division or channelling of smoke and fumes along even really long sub-division and channelling lines.
  • any length of sub-dividing or channelling line can be made up from individual overlapping apron portions without any fear that, in the event of a fire, clear spaces or gaps along the longitudinal edges will allow smoke and fumes to escape. In the event of fire, therefore, the prerequisite that escape routes and the like must be kept reliably free from developing smoke and fumes is satisfied.
  • each apron portion which may be of manageable width is expediently supported on a separate roller, the roller being selected in length in accordance with the width of the respective apron portion and constructed in a structurally simple manner.
  • the rollers of adjacent apron portions are in a staggered arrangement so that the adjacent apron portions can be fed from horizontally oppositely disposed sides of the sub-dividing or channelling line to an aligned throughway, a positive guidance arrangement inside the housing ensuring, by a corresponding structural adaptation of housing parts, that the overlapping longitudinal side edges of adjacent apron portions can be lowered in such a way that they are closely adjacent one another.
  • the housing parts and consequently individual apron parts are, therefore, preferably designed on the unit construction or modular principle for making up really long sub-dividing lines so that such lines can be assembled in an easily handled manner, even around corners or through angled portions of the lines, in such a way that when the apron is rolled up, its appearance is visually harmonious.
  • the smoke apron generally designated 1 in the drawings consists of a woven fabric and is intended to be installed under ceilings in buildings or under balconies in buildings or their breast work.
  • the smoke apron according to the invention comprises housing parts 2, 3, 4 (Fig. 2, Fig. 5) and housing parts 5, 6 (Fig. 3, Fig. 4) which have to be assembled on the modular or unit construction principle to provide a finished smoke apron 1 of virtually any length along a sub-division or channelling line.
  • an apron portion 7 and each portion is disposed on a separate roller 8 with an electric motor drive 9 so that it can be rolled up and down.
  • the adjacent longitudinal edges 10 of adjacent apron portions 7 overlap by the amount X which ought expediently to be at least 80 mm.
  • weights which, in the closed condition of the apron portions 7, close off the throughway 11 (Figs. 2 to 4).
  • the throughway 11 and the weight 12 of each apron portion 7 are of matching cross-section so that the individual housing parts 2 to 5 are closed from the under side by the weights which are aligned flush when the apron portions 7 are rolled up.
  • the smoke apron 1 as a whole is designed on the modular or unit construction principle.
  • the individual housing parts 2 to 5 have, in each case, adjacently disposed housing boxes 13, 14, in the middle plane of division of which the throughway 11 is located. It is in this plane of division, too, that the apron portion is unrolled, the apron being positively guided between the housing boxes 13, 14 as it is unrolled and re-rolled.
  • the individual rollers 8 and also the housing boxes are so provided that the adjacent apron portions 7 with their overlapping longitudinal edge portions can be raised and lowered with positive guidance.
  • alternate pairs of housing boxes 13 and 14 are made to a shorter and longer construction, respectively, and any desired smoke apron length can be created.
  • the individual rollers 8 which are of the same or different lengths are provided alternately in and made to fit the housing box 14 and the housing box 13.
  • the respective apron portions 7 with their separate rollers 8 are disposed in the housing so that they overlap each other in a longitudinal direction but with the rollers offset in the horizontal direction by 180° with respect to the longitudinal centre line of the housing.
  • the apron portion 7 and thus the smoke apron as a whole is adapted to be supported in its starting position, in which it is rolled up in the housing, by an electric motor drive.
  • direct current motors are provided in the relevant rollers 8 and these are connected to electronic measured-value-processing means.
  • the said electronic measured-value-processing means comprises a fire alarm so that in the event of fire, a regulation of the motor voltage downwards causes the respective portion of smoke apron to be lowered. While this is happening, the direct current motor runs at the same time so that the apron portions are moved downwards in a controlled fashion. This obviates any risk of a sudden lowering of the apron possibly injuring anyone underneath.
  • the direct current motors or the control arrangements are such that while the apron portions are being rolled up, the control units recognise when the respective throughways have been closed, since the direct current motor encounters a resistance when this happens.
