Definitions

  • the invention relates to a casing for multi-layer chimneys with an inner tube, consisting of a base layer and at least one heat-insulating layer made of a moldable material that is attached to it from the start on the inside.
  • Such a casing stone is known from DE-AS 29 40 188. There is no air layer between the shells of the chimney.
  • the air layer is usually between the thermal insulation layer and the casing, i.e. the thermal barrier coating is exposed to the moisture and chemical effects of the condensate penetrating through the inner tube.
  • the thermal barrier coating is exposed to the moisture and chemical effects of the condensate penetrating through the inner tube.
  • the invention has for its object to provide a casing of the type mentioned, with which not only a simplification and acceleration of construction work can be achieved with reliable, consistent quality, but at the same time also an improvement in the thermal insulation and ventilation of the chimney.
  • the aforesaid thermal insulation layer which consists of a moldable material, is provided on its inside with projections or ribs bridging an air layer for lateral support of the inner tube.
  • the outer, statically load-bearing layer and one or more thermal insulation layers firmly connected to it form a transport and assembly unit which is largely independent of external influences and can be handled in a practical manner.
  • the base layer of the casing stone and the heat insulation layer are each individually formed and put together after hardening.
  • the thermal insulation layer is molded onto the base layer.
  • the base layer can first be shaped and, once it has hardened, the thermal insulation layer can be molded on directly, the base layer serving as outer formwork.
  • a preferred embodiment is characterized in that the thermal insulation layer and the base layer are designed to be mutually transitional by simultaneous hardening or setting without an intermediate layer at the boundary layer.
  • the statically load-bearing layer of the mantle stone can consist of any material previously used for this layer, preferably z. B. made of lightweight concrete.
  • Pourable, heat-resistant, porous materials are available for the thermal insulation layer, of the type that have previously been used in principle for subsequently pouring out the space between the inner tube and the casing stone and are available, for example, under the trade names Perlite or Liapor.
  • Perlite or Liapor In principle, highly porous or foamed or inflated mineral materials or material mixtures are generally suitable.
  • the invention is not restricted to a single thermal barrier coating.
  • two or more interleaved thermal insulation layers may be present, z. B. that thermal insulation layer on which the inner tube is supported, consists of a particularly strong and / or heat-resistant material, while a further thermal insulation layer is lighter in comparison and offers a particularly effective thermal insulation.
  • the essential feature of the invention are the projections or ribs projecting radially inward from the molded thermal insulation layer and bridging an air layer for lateral support of the inner tube. If ribs are provided instead of individual, selectively arranged projections, then these should preferably extend over the entire axial length of the thermal insulation layer.
  • the air layer generated by means of these projections or ribs and expediently surrounding the inner tube has a width of approximately 1.5 cm or more.
  • the projections or ribs are preferably molded onto the thermal insulation layer, but there is also the possibility of prefabricating them individually and with the thermal insulation layer and / or the base layer, e.g. by positive engagement.
  • the proposed location of the air gap regardless of whether the air is used as an additional heat insulation layer or provides ventilation through air circulation, has the advantage that the heat insulation layer is largely shielded from heat, moisture and chemical influences by the air layer is.
  • a further air layer optionally used for thermal insulation or rear ventilation can be obtained according to the innovation in that the thermal insulation layer is firmly connected to the base layer of the casing stone by bridges or projections bridging an air layer. This additional air layer is located radially outside the thermal insulation layer.
  • the projections or ribs bridging them can optionally be formed from the material of the thermal insulation layer or the material of the base layer of the casing stone.
  • the support layer is stepped or beveled outwards at at least one axial end.
  • a mortar joint preferably filled with heat-insulating mortar, only in the outer, stepped or beveled area, while the sections of the heat-insulating layer and, if appropriate, the radially inner area of the end faces of the support layer of the casing stones are butted against one another.
  • the same casing block with molded thermal insulation layer can be used for different insulation effects depending on the conditions of the application.
  • the better thermal insulation is obtained when the air layer between the inner tube and the thermal insulation layer is locked in and forms a thermal insulation layer itself.
  • the thermal insulation of the inner tube which usually consists of chamotte, such as. B. in heating systems that are operated in the condensate area, is not necessary or even undesirable
  • the air layer between the inner tube and the thermal insulation layer of the casing can serve through rearward ventilation of the inner pipe through the air inlet or outlet openings arranged at the lower and upper ends of the chimney.
  • the air outlet openings on the chimney head are to be formed in a known form by rain-repellent grid structures.
  • a casing stone is provided in a further preferred embodiment of the innovation, which is formed with a lateral opening, which is circumferential through a from the outer wall to the inner tube reaching lining piece is limited, which can optionally be provided with or without air inlet openings, which in the assembled state are connected to the air layer between the inner tube and the heat insulation layer.
  • the chimney door on the inner tube is accessible through the lining.
  • a lining piece is preferably used in connection with a casing stone with a side opening in the boiler room, which can be connected from an interior to a flue gas pipe of a heat generator. up to the inner tube extending pipe socket, this surrounds this at a distance, up to the air layer next to the thermal barrier layer and the distance bridging connecting members, which are provided with air inlet openings.
  • a lining piece which considerably facilitates the assembly of ventilated chimneys, is also advantageous if the ventilated annular air gap of the chimney is located radially outside the thermal insulation layer.
  • the air inlet or outlet openings in the above-mentioned chucks can optionally also be designed to be fully or partially closable.
  • the casing block shown in FIGS. 1 and 2 consists of an outer, statically load-bearing layer 10 and a heat insulation layer 12 firmly connected to it.
  • the thermal barrier coating 12 has formed on the inside vertical ribs 14, on which an inner tube 16, for. B. supported from chamotte.
  • the thicknesses of the base layer 10 and the thermal barrier layer 12 depend on the requirements of the respective application.
  • the height of the ribs 14 is dimensioned such that an air layer 18 of at least about 1.5 cm in width remains free between the heat insulation layer 12 and the inner tube 16. Between the ribs 14 and the inner tube 16 there is a slight play of the order of about 1 mm or a few mm in order to ensure the free mobility of the inner tube 16.
  • the outer jacket and / or the inner tube 16 can also have any other cross-sectional shapes, only the ribs or projections 14 having to be adapted in their arrangement and size.
  • the one-sided longitudinal section according to FIG. 2 through the casing block according to FIG. 1 shows that the thermal insulation layer 12 and the Ribs 14 extend over the entire axial length of the casing stone.
  • the support layer 10 is chamfered outwards at one axial end.
  • the inclined surface is designated 20. In the example, it extends over approximately 2/3 of the thickness of the base layer 10, so that when the chimney is erected, the casing stones can be placed on top of one another in a blunt and practically seamless manner with the inner regions of the end faces of the base layer 10 and with the insulation layers 12.
  • the annular gap 22 formed by the inclined surface 20 or a step formed in this area between superimposed casing stones is filled with thermal mortar. This mortar joint is thus limited to the radially outer region of the base layer 10.
  • the insulation layer 12 could also be longer than the base layer 10 by the height of a normal flat mortar joint in the axial direction.
  • FIGS. 1 and 2 show the casing stone according to FIGS. 1 and 2 in an embodiment with a lateral opening 24 through which a chimney door 26 is accessible.
  • the fireplace door seals a z. B. to clean the chimney exposed opening in the inner tube 16.
  • the support layer 10 is connected to a lining piece 28 which delimits the lateral chimney opening 24 at the circumference and can have a round or polygonal cross section.
  • the chuck 28 is made of a refractory material, e.g. B. sheet.
  • Air inlet openings 30 are provided in the lining piece 28 and connect the outside atmosphere to the air layer 18.
  • this is connected to the outside atmosphere via air outlet openings on the chimney head, so that the air layer 18 in the chimney rises continuously from the bottom to the top, thereby ventilating the inner tube 18.
  • a lining piece 28 without air inlet openings 30 is used and no air outlet openings are provided on the chimney head, since the lining piece 28 reaches up to the inner tube 16, the air layer 18 is enclosed and forms an additional layer itself Thermal insulation layer.
  • the lining piece 28 is formed with an enlarged outer circumference in the area of the base layer 10 and the insulation layer 12 and with a narrower circumferential area in the area of the air layer 18, the embodiment according to FIG. 5 is seen Lining piece 32 with a jacket which is constant from the outside inwards, the cross section of which is smaller than the cross section of the lateral opening in the support layer 10 and the insulating layer 12, so that a space for air entry is obtained between these and the lining piece 32.
  • the design of the lining piece 28 or 32, the reveal of the lateral opening in the base layer 10 and the insulating layer 12 and the air inlet openings 30 permits numerous design variants, including those with air inlet openings 30 that can be optionally opened and closed.
  • pieces of lining of the type described here can always be used at the cleaning openings of chimneys, regardless of the chimney cross section described here, when rear ventilation is provided.
  • the chimney door is mounted on the lining piece 28 or 32.
  • each guide frame 15 consists of a frame part which is adapted to the cross section of the inner tube 16 and is in contact with the latter and has radially extending struts which form the projections 14.
  • the ends of the struts can, as shown in FIG. 6, be bent in a hook shape in order to cling to a step-like shoulder of the upper surface of the support layer 10.
  • a guide frame 15 according to FIG. 6 hinders the air circulation between the inner tube 16 and the heat insulation layer 12 even less than the ribs 14 according to FIGS. 1 to 5, on the other hand it represents a special assembly part.
  • the ribs 14 In order to obtain an air exchange between the cavities laterally delimited by the ribs 14 also in the embodiments according to FIGS. 1 to 5, the ribs 14, as indicated by dashed lines in FIG. 2, can be chamfered at at least one end.
  • guide frame 15 is shown in section in FIG. 6 and, for better illustration, it is shown again in perspective, it is shown in plan view in FIG. 7. 7 is modified in comparison with the previously described exemplary embodiments in that, in addition to the air layer 18, it also has a further air layer 19 between the support layer 10 and the heat insulation layer 12. If the guide frame 15 is firmly enclosed in the support layer 10 and the heat insulation layer 12 during the molding process, it can connect these two parts of the casing block to one another. Alternatively, protrusions (not shown) can be formed on the support layer 10 and / or on the heat insulation layer 12, which bridge the air gap between these two layers and connect them to one another.
  • air inlet openings 30 can be provided in a chuck for a fireplace door. In practice, however, this could lead to problems if the cleaning doors, which often happens, are not located in the installation room of the heat generator and the room in which they are located is particularly cold. In such cases, it will be advisable to place the air inlet openings 30 in a lining according to FIG. 8, which is used to connect the flue gas pipe of the heat is determined in the installation room. An additional heating of the air used to ventilate the chimney is achieved by leaving the flue gas pipe of the heat generator without insulation in the area of the chimney flue.
  • a circumferential bead 38 is formed in the pipe socket 36, into which a temperature-resistant rope or a permanently elastic, temperature-resistant mass is introduced in order to seal the flue gas pipe.
  • the seal also serves to largely prevent the transmission of sound and vibrations when the heat generator is in operation.
  • the pipe socket 36 is provided with a flanged edge at the end abutting the inner pipe 16. This prevents the pipe socket 36 from penetrating into the fire tube. Otherwise it could happen that the flue gas pipe could be deformed by the elongation of the fireclay pipe or the latter could be hindered.
  • the lining piece 34 also has a casing pipe 40 surrounding the pipe socket 36 at a distance, the length of which is calculated from the thickness of the plaster as well as the supporting and thermal insulation layer of the casing stone.
  • the inner edge of the casing tube 40 is therefore preferably flush with the inner edge of the thermal insulation layer 12.
  • the casing tube 40 is firmly connected, for example welded, to the pipe socket 36 via a radially extending connecting wall 42. 3 to 5, there are air inlet openings 30 in the connecting wall 42. They can be designed, for example, as round holes, but also, for example, as elongated holes that extend radially or in the circumferential direction. The size and number depend on the amount of air to be introduced.
  • FIG. 9 shows a solution to this problem.
  • the casing tube 40 By forming the casing tube 40 as an elongated, upright rectangular tube, 36 large air inlet openings 30 can be obtained above and below the pipe socket.
  • the ventilation of the chimney is not required in individual cases, instead of the lining piece 34 with air inlet openings 30, one without air inlet openings or with optionally closable air inlet openings can be used.
