Definitions

  • the invention relates to a smoke extraction duct, in particular one of the fire resistance class L90.
  • Fires may produce smoke and, depending on the type of combustible material, may also contain toxic gases. On the one hand, these can be life-threatening and, on the other hand, obstruct the unobstructed view, which is why, in particular, escape routes are to be kept free of corresponding gases and / or smoke.
  • Smoke extraction systems are used for the extraction of gases and / or smoke, with appropriate smoke extraction channels are provided, can be passed through the gases and / or smoke from the fire to the outside.
  • the invention proposes a smoke extraction duct with an inner wall and one of them, forming a gap spaced outer wall, wherein the inner wall and the outer wall are each formed of calcium silicate, and arranged in the gap space supporting framework, which is formed from hollow sections of steel, and arranged in the gap space strips of calcium silicate, with which the inner wall and the outer wall are mechanically connected ,
  • the smoke extraction duct according to the invention is double-walled. He has an inner wall on the one hand and an outer wall on the other. Both the inner wall and the outer wall are formed from calcium silicate, so that a substantial insensitivity to hot gases and / or hot smoke is given, which ensures a corresponding fire resistance class. Preferably, the inner wall and the outer wall are dimensioned in such a thickness that the fire resistance class L90 is reached. Other embodiments are also conceivable here, that is also those for maintaining a higher or a lower fire resistance class.
  • the inner wall and the outer wall are each preferably formed of calcium silicate plates.
  • the calcium silicate plates can be composed of individual sections.
  • the inner wall and the outer wall are spaced apart to form a gap space.
  • a support frame In the gap between the inner wall on the one hand and the outer wall on the other hand is a support frame. This is formed from individual hollow steel profiles and provides the stiffening of the final channel, so that a sufficient stability of the entire channel is given.
  • the walls formed of calcium silicate plates abut against the hollow profiles of the support framework.
  • a specially designed connection between the calcium silicate plates on the one hand and the hollow sections of the support frame on the other hand is not provided.
  • strips of calcium silicate are arranged in addition to the support frame.
  • the inner wall on the one hand and the outer wall on the other hand are mechanically interconnected. It is insofar arranged a mechanical composite of double-walled Calcium silicate plates created, wherein in the gap between the two plates, that is, between the inner plate on the one hand and the outer plate on the other hand, a support frame made of hollow steel profiles is formed, which serves the overall stability of the smoke control.
  • a calcium silicate plate is firstly equipped with calcium silicate strips in a first step.
  • a support frame formed from hollow steel profiles is to be laid.
  • a second calcium silicate plate is to be placed on the support frame, which plate is to be connected to the calcium silicate strips arranged between the first and the second plate.
  • the result is a sandwich-like structure of a first and a second calcium silicate plate, which are interconnected via interposed calcium silicate strips.
  • the support frame also formed between the two calcium silicate plates provides the desired stability.
  • a sandwich composite formed in the manner described above serves as a side wall for a smoke extraction duct formed in accordance with the invention.
  • a side wall for a smoke extraction duct formed in accordance with the invention In a cross-sectionally rectangular configuration of the smoke extraction duct four such side walls are used, which are interconnected along their abutting edges.
  • the mechanical connection in particular the mechanical connection between the inner wall and / or outer wall with the calcium silicate strips arranged therebetween, takes place by clamping.
  • Such a connection has proven to be fail-safe and allows easy to carry out assembly, especially when using Klammerschussierin.
  • the support frame is formed from individual profile segments, wherein it is preferred that the profile segments are arranged one behind the other in the channel longitudinal direction.
  • two adjacent profile segments have a maximum distance of 600 mm.
  • other maximum distances must be maintained to achieve the required stability, for example, of 500 mm, 400 mm or 300 mm.
  • the clear channel diameter such a distance between the individual profile segments of the framework is chosen, which provides the required overall stability of the finished trained smoke control.
  • a profile segment consists of individual hollow sections made of steel, which are preferably welded together.
  • a profile segment is preferably formed ring-like, thus has a plurality of circumferentially circumferentially arranged peripheral hollow profiles.
  • a profile segment consists of four hollow sections, which are welded together to form a rectangular frame.
  • Such a frame represents the profile segment, wherein a plurality of such frames arranged in the channel longitudinal direction one behind the other, the support frame according to the invention.
  • each profile segment more preferably each hollow profile of each profile segment is directly adjacent to a calcium silicate strip.
  • a displacement movement that is, a relative movement between the calcium silicate plates on the one hand and the support frame on the other hand is not possible in particular in such a construction.
  • the gap between the inner wall on the one hand and the outer wall on the other hand is otherwise filled with mineral wool.
  • the desired fire resistance class L30, L60, L90 or L180 is achieved.
  • a channel according to the invention may be operated with an operating pressure of +500 bar to -1,500 bar and is tested with a maximum temperature of 300 ° C.
  • FIGS. 1 to 3 let recognize in different representations a smoke extraction duct 1 according to the invention.
  • the smoke extraction duct 1 has a total of four side walls 10, 11, 12 and 13, as can be seen in particular from the illustration Fig. 2 results. These side walls 10, 11, 12 and 13 are connected to form the smoke extraction duct 1.
  • the smoke extraction duct 1 has an overall rectangular cross-section configuration, as also in particular from the illustration Fig. 2 results.
  • Each side wall 10 to 13 has an inner wall 2 and an outer wall 3, which are formed while leaving a gap 4 spaced from each other.
  • the inner wall 2 and the outer wall 3 are each formed from plates of calcium silicate. This factual context arises in particular from the presentation below Fig. 3 ,
  • each profile segment 14 is formed from four hollow profiles 5, which are welded together.
  • each profile segment 14 is like a ring-like frame, that is, the hollow sections 5 of each profile segment 14 are circumferentially formed on the circumference of the channel.
  • An inner wall 2 and an outer wall 3 are provided, which are mechanically connected to one another via calcium silicate strips 7 arranged therebetween, in particular by clamping.
  • An arranged in the gap between the inner wall 2 and outer wall 3 support frame 15 serves to achieve a sufficient stability of the finished smoke evacuation channel.
  • the inner wall 2 and the outer wall 3 forming calcium silicate plates may be formed of individual sections 9. These are preferably not directly connected to each other, but are each supported via corresponding calcium silicate strips 7, with which they are mechanically coupled.
  • the distance A (see. Fig. 3 ) between two adjacent hollow profiles 5 of two adjacent profile segments 14 is a maximum of 600 mm. Depending on the expected load, other distance values may also be provided.
  • Such a duct can be operated at an operating pressure of +500 bar to -1,500 bar and up to a temperature of 300 ° C.
