Definitions

  • the invention relates to a shaft for chimneys or Exhaust pipes to accommodate an internal one, at a distance to the inner wall of the chimney or one Exhaust pipe for combustion plants, consisting of one another aligned and connected to each other on the front, prefabricated shaft elements made of mineral material.
  • Such shafts must have a fire resistance of 90 Minutes (fire resistance class F 90).
  • fire resistance class F 90 The one with it related requirement that the material used is not for such shafts, the usual type of cement-bound material easily met. In addition, the used Material but also a sufficient thermal insulation effect exhibit. This is necessary so that on the one hand in In the event of fire, an inadmissible heating of the outer surface of the Shaft is avoided, which leads to inflammation of could lead to neighboring flammable components; on the other hand but should also be too strong in normal operation Heat transfer can be prevented.
  • Manhole elements must not be too heavy for the To reduce transport costs and especially the Facilitate handling on site.
  • the usual cementitious materials are relatively heavy, so that further reduce the weight of each Manhole elements is only possible in that the length of the Manhole elements is reduced. But this increases for a given height, the number of required Manhole elements. This leads to an increased cost and Workload.
  • the object of the invention is therefore a shaft train the genre mentioned so that he not only all requirements regarding fire resistance and Isolation effect fulfilled, but that the individual Manhole elements even with a relatively large length are so light that they can be easily transported and especially easy to handle during assembly can be.
  • Density of this foamed ceramic material is very low, so that even relatively large shaft elements are still very much are light and therefore especially during assembly. are easy to use.
  • the thermal insulation effect made of foamed ceramic material Shaft very high, so that when used for chimneys Effort for thermal insulation of the interior Smoke pipe significantly reduced and the wall thickness of the Shaft can be chosen smaller.
  • the shaft has one high fire resistance, so that it meets the requirements of Fire resistance class F 90 met with certainty.
  • the foamed ceramic material preferably contains inorganic fillers, with which its properties, especially regarding the fire resistance duration and the Compressive strength, can be influenced even more favorably.
  • a special increase in the fire protection effect can be thereby achieve that the foamed ceramic material up to 39 percent by weight chemically bound water of crystallization contains.
  • the shaft elements in their on each other butting end faces each have a concentric annular groove have and that in the annular grooves of adjacent end faces a common annular connecting nipple was added is.
  • the connecting nipple preferably made of metal creates a mechanically stable connection of adjacent shaft elements, which are also against each other be centered; on the other hand bridges the metallic annular connection nipple the butt joint adjacent shaft elements and thereby prevents one possible flame penetration even if the butt joint due to mechanical or thermal influences or insufficient connection gapes.
  • the chimney shaft 1 shown in Fig. 1 takes up Smoke pipe 2 of a furnace on, for example, from Stainless steel and is surrounded by an insulating layer 3.
  • the smoke tube 2 provided with the insulating layer 3 is included the same distance on all sides concentric to the inner wall of the shaft 4 of the chimney shaft 1 arranged so that in between an annular gap 5 is formed.
  • the chimney 1 consists of several, each frontally connected to each other and to each other aligned, prefabricated shaft elements 6. In Fig. 1 two such shaft elements are shown.
  • Each shaft element 6 consists of foamed ceramic material based on aluminum oxide and silicon oxide. Water glass is used as a binder. Organic fillers can also be used.
  • the foamed ceramic material used for the chimney shaft 1 shown has closed pores which were formed by adding gas-forming chemicals during the casting process. The proportion of pores is selected so that the foamed ceramic material has a density of 0.5-1.7 g / cm 3 .
  • connection nipple 9 added, which consists of metal and essentially forms a cylinder.
  • connection nipple 9 each have an outer spring washer 10 or Rubber ring on the flat formed there Circumferential groove of the connecting nipple 9 is inserted and on the Inner wall 8a of the annular groove 8 comes to rest.
  • the connecting nipple 9 has a radially projecting one Circumferential rib or individual radially projecting knobs 11 on in an annular recess 12 at least one of the two end faces 7 is arranged.
  • the illustrated Embodiment have both meet and with each other, for example, by refractory gluing connected end faces 7 each such an annular Recess 12 so that in the area of the butt joint 13 between the two shaft elements 6 one of the ring grooves 8 on Circumferentially projecting annulus arises that the Receiving circumferential ribs or protruding knobs 11 and thereby the connection nipple 9 positively in its position holds in which he bridges the butt joint 13.
  • each shaft element 6 ' consists of foamed ceramic material based on Aluminum oxide and silicon oxide with water glass as a binder, as already in the previously described embodiment was explained.
  • Each at the junction of two shaft elements 6 ' is a connecting nipple 9 'bridging the butt joint 13' arranged on the inner wall 4 'of the shaft.
  • the example of Sheet metal existing connection nipple has a radial projecting circumferential rib or individual radially projecting Studs 11 'on in an annular recess 12' the shaft inner wall 4 'in the area of each butt joint 13' is arranged.
  • the connecting nipple 9 ' carries on it Outside rubber ring seals 15, each on the Shaft inner wall 4 'rest.
  • connection nipple 9 (Fig. 6) rectangular.
