Definitions

  • This object is achieved in that the cross section of the ventilation duct is completely filled over a certain length with a flowable, highly heat-dissipating latticework made of expanded material, preferably expanded metal made of aluminum foil, at the points at which it penetrates the boundary between two fire sections.
  • an insert frame is suitable for this purpose, the dimensions of which are adapted to the free cross-section of the ventilation duct and also have transverse struts in front of and behind the stretching material transversely to the direction of flow.
  • Such an insert frame could either be filled with a plurality of layers of stretch material lying more or less parallel to one another, or also with packing elements which, for example, have a spherical shape, which also consist of stretch material, or a mixture of both.
  • Decisive for the choice between the two variants is, on the one hand, the specific flow resistance and the strength of the air filter effect which occurs as a result and, on the other hand, the available axial length of such an insert frame, measured along the flow direction of the channel.
  • Such an insert frame can be introduced very easily into the cross section of the ventilation duct, for example through a door which is arranged in one of the walls of the ventilation duct.
  • the expanded material due to its additional function as an air filter, becomes contaminated more or less quickly, depending on the place of use in such a ventilation system, which can also increase the flow resistance in the corresponding ventilation duct, it is necessary to regularly expand the expanded material contained in the insert Clean intervals or even replace.
  • the insert frame itself can be opened in order to enable the layers of expanded material or the packing to be removed easily.
  • either a position of the cross struts can be separated from the sides of the insert frame, or else one side can be separated from the other pages or at least pivoted away. In this way, it is possible to refill the insert frame in a short time.
  • the cross braces that run transversely to the flow direction of the ventilation duct must be at a distance that is significantly smaller than the size of the individual filler element in order to prevent the filler elements from being blown away due to the air flow in the ventilation duct.
  • the cross struts can be single and parallel struts running transversely to the direction of flow of the ventilation duct or a sufficiently large grid made of a heat-resistant material, e.g. an expanded metal.
  • the insert frame In the event of a fire, this prevents the filling that dissipates the heat very strongly from the walls of the ventilation duct, the insert frame also prevents the flame from striking through or hinders or defends the fire roller or also deflagrates in the area of the ventilation duct behind the insert frame in the direction of flow, i.e. the next fire section, since rapid heat dissipation prevents the ignition temperature from reaching the expanded material, at least for some time.
  • This function of heat dissipation is only fully fulfilled by the expanded material if it is a material, for example a metal, such as aluminum, which inherently has a very high conductivity, and if this material is not used in any way was insulated from the ambient air against heat. This means that this stretch material is neither deliberate with any insulation effecting material may be coated, such a coating should be present unintentionally, for example, due to heavy contamination. For this reason, regular cleaning and maintenance of the insert frame and its contents is recommended from time to time.
  • FIG. 1 and FIG. 2 show a longitudinal section through a ventilation duct which consists of the walls 1, an opening being located in one of the walls, which opening is closed from the outside by a door 2 which is attached to the wall 1 by means of a hinge 4 is articulated near the opening of the wall.
  • this door 2 In the closed state, this door 2 is held against the wall 1 by a locking device (not shown), a circumferential, fire-resistant seal 3 being located between the outer edge of the door 2 and the wall 1.
  • the insert 10 can be easily removed from the cross section of the ventilation duct.
  • the insert 10 consists of pages 7, whose outer contour must be adapted to the inner contour of the wall 1 of the ventilation duct.
  • Transverse struts 8 are located transversely to the sides 7 and thus also transversely to the flow direction 6 of the ventilation duct at the front and rear front of the insert frame 10, which in FIG. are designed as a perforated plate.
  • the space enclosed within the insert frame 10, that is to say the sides 7 and the cross struts 8, is completely filled with packing elements 5 which consist of expanded material, only a part of which is shown in FIG. 1 by way of example.
  • the perforation of the perforated plates shown in FIG. 1 as cross struts 8 must be smaller than the diameter of the filler 5 in order to ensure that the filler is retained between the two perforated plates.
  • the insert frame 10 shown in FIG. 2 contains a plurality of layers 9 of expanded material, for example expanded metal, of which only two layers are also shown by way of example in FIG. 2, while in practice the entire space enclosed by the insert frame with a large number of such mutually and each other the sides 7 touching layers 9 is filled.
  • the transverse support by the cross struts 8 has to be less extensive be so that the cross struts 8 can be carried out, for example, by individual, parallel rods or struts, as is the case in FIG.
  • FIG. 1 applies to loading and emptying the insert frame 10.
  • FIG 3 a longitudinal section through the walls 1 of a ventilation duct is shown, in which no longer a fixed insert 10 is inserted, but in which there are two transverse struts 8 fastened transversely to the flow direction in the cross section of the ventilation duct, between which the latticework, in this Case the packing 5 made of expanded metal, are kept.
  • Sufficiently dimensioned perforated sheets, grids and thus also sufficiently strongly dimensioned expanded metal can be used as cross struts 8, which in the case shown here are only spread between the walls 1 of the ventilation duct, which is indicated by the same deflection of the cross struts 8 downwards.
  • any other type of fastening would also be possible.
  • the introduction takes place in such a way that, after the door 2 has been swung open, the lower cross brace 8 is first fastened in the cross section of the ventilation duct, after which the desired amount of expanded metal, in this case the filler 5, is applied to the lower cross brace 8.
  • the top cross strut 8 is then introduced into the cross section between the walls 1 to cover upwards.
  • individual layers 9 of expanded metal can be used to fill the distance between the two cross struts 8, or a mixture of layers 9 and filler 5 consisting of expanded metal.
  • correspondingly dimensioned layers of expanded metal as cross struts 8
  • these cross struts 8 would certainly assume a double function of static support and heat dissipation, so that in this case the lower and upper cross struts 8 are not only one but in each case a plurality of layers of adequately dimensioned expanded metal could be introduced, between which additional packing elements 5 may then be located.
