Definitions

  • the present invention relates to a chimney component for single-layer or multi-layer chimneys, which consists of fired clay and is manufactured using perforated technology, with a jacket area, an insulation area adjoining the jacket area and a duct for the flue gas, the jacket and insulation area being formed in one piece and have a multi-row sheet, in particular concentrically extending air holes, which are arranged distributed over the cross section of the jacket and insulation area.
  • Chimney components known from the prior art are in several parts, they consist of a so-called casing stone made of concrete, on the inner recess of which an insulating plate made of insulating material is inserted, which in turn surrounds the internal flue gas pipe. It is therefore a three-part construction, the individual components are manufactured in isolation and only put together afterwards.
  • the manufacture of the chimney component therefore proves to be complex on the one hand due to the necessity of the subsequent assembly of the individual parts and on the other hand due to the comparatively complex manufacturing process of the individual parts (casting of the concrete casing block, production of the insulation board).
  • the subsequent assembly of the individual parts in the event of dimensional inaccuracies requires additional processing steps, which can significantly increase the costs of a chimney component of the generic type.
  • a chimney component of the aforementioned type is known from DE-A-3402612, where it is proposed, in particular to increase the thermal insulation capacity and stabilize it against thermal overload, to arrange a thermal insulation material in some holes of the perforation and to provide the inner wall of the shaped shells with a gas-tight glaze . Longitudinal ribs have been described for spacing an inserted smoke pipe from the glazed inner wall of the shaped block.
  • At least one support section or support web is provided in the form of an uninterrupted mass web which penetrates the entire set of air holes and which supports the blank component during or after the extrusion guaranteed.
  • the at least one support section or support web formed during extrusion or extrusion can extend transversely to the longitudinal axis of the chimney component in such a way that a support effect of the extruded blank can be achieved.
  • a support effect is also achieved during the drying process, in which, under certain circumstances, re-plastification can occur due to the evaporation of moisture.
  • the mass section or mass web has at least one row of holes through holes in the axial direction, on the one hand a weight saving is achieved, and on the other hand the possibility is created in a simple manner of side regions of the chimney component along the holes of the mass section or mass web from the base body of the chimney component to separate.
  • the holes in the individual earth section or earth bridge consequently also act as predetermined breaking points or predetermined separation points.
  • the chimney component preferably two support sections or support webs are tangential to the duct receiving the flue gas pipe and if the support sections or support webs are designed as hole sections or mass webs, the can
  • the area of the chimney component between the two support webs can be easily removed and replaced by a chimney door or the like, or the component can be used as a component that is open on one side.
  • a particularly high support effect results from the fact that a plurality of support sections or support webs or mirror and / or point symmetry are arranged and preferably run perpendicular to the outer surface of the chimney component.
  • the support sections or support webs are in the lower, ie. H. half of the cross section of the chimney component assigned to the support.
  • the invention relates to a chimney component, for single or multi-layer chimneys, which consists of fired clay and is manufactured using perforated technology, with a jacket area, an insulation area adjoining the jacket area and a duct for the flue gas, the jacket and insulation area being formed in one piece are and have a family of concentric air holes in particular, which are arranged distributed over the cross section of the jacket and insulation area.
  • At least one support section or support web is provided in the form of a mass web, which is arranged in the longitudinal direction of the channel for the flue gas within the same, which thereby ensures a support effect of the component blank during or after the extrusion that it connects two inner wall areas of the channel located on one side of the longitudinal symmetry plane of the channel.
  • a support web also prevents the extruded strand from collapsing during manufacture.
  • Such a support web can be removed by knocking out after the chimney component has burned, so that ultimately there is a free cross section of the channel.
  • Molded-in predetermined breaking points can expediently be provided to facilitate the knocking out of the support web.
  • the jacket and / or insulation area has an extension which contains a supply air shaft and which can also be molded immediately in the extrusion or extrusion process.
  • a flue gas pipe to be used separately is facilitated, which can expediently be a glass pipe, metal pipe, plastic pipe or stoneware pipe.
  • an additional insulating layer can be expediently provided between the flue gas pipe and the jacket or insulation area. At the same time, this ensures a good hold of the flue gas pipe.
  • Another expedient embodiment of the chimney component according to the invention is characterized in that the jacket area, the insulation area and the flue gas pipe are formed in one piece and consist of fired clay.
  • the entire chimney component can be produced continuously using the extrusion or extrusion process, and there is no need to subsequently insert the flue gas pipe. Only the upper and lower surfaces of the respective chimney component have to be ground flat.
  • the flue gas pipe is spaced from the inside of the insulation area by molded-in spacer elements, thereby creating gaps that can be used as ventilation ducts.
  • the inside of the flue gas pipe can expediently be coated, preferably, for. B. be glazed.
  • a flue gas pipe in the form of a glass pipe, metal pipe, plastic pipe or stoneware pipe and / or by coating the inside wall of the flue gas pipe, for example with a glaze
  • the durability of a chimney is significantly increased. This is due to the fact that these measures enable the operation of a chimney system which is insensitive to moisture.
  • the pollution of the air by the house fire and the scarce energy resources are known.
  • Environmentally friendly and energy-saving heating systems will therefore be essential in the future.
  • condensing low-temperature heating systems will become increasingly important in the future.
  • a chimney constructed from such chimney components can also be used for cool and aggressive exhaust gases, which can form an aggressive condensate.
  • a very high degree of tightness can also be achieved by inserting temperature-resistant, acid-resistant and moisture-insensitive seals.
  • seals can be made of plastic, especially of elastomers (synthetic rubber), such as. B. polychloroprene or chlorobutadiene or be formed on a mineral or ceramic basis.
  • elastomers synthetic rubber
  • B. polychloroprene or chlorobutadiene or be formed on a mineral or ceramic basis.
  • concentrically extending groups of holes are provided in the jacket and / or insulation area, with the mass areas of the other group located between the holes preferably opposite the holes of the one group.
  • volume gradient is adjustable in the radial direction. In this way, the volume and thus the thermal insulation property in the radial direction can be adjusted according to the respective requirements.
  • the teaching according to the invention is not only limited to one-piece chimney components with or without a flue gas pipe, it is also provided according to the invention that the chimney component consists of several one-piece shell parts which are connected via form-locking means, in particular via tongue-and-groove projections and depressions.
  • form-locking means are provided, preferably in the form of tongue-and-groove projections and depressions, which also make it much easier to align the individual shell parts to one another.
  • Another object of the present invention is to create a multiple chimney system which can be constructed in a simple manner, manages with the smallest possible number of individual parts and is as space-saving as possible.
  • a chimney component according to at least one of claims 1-17 is provided as the basic building block and the individual building blocks can be connected to one another via positive locking means.
  • a multiple chimney system can be produced in an incredibly simple manner, as in a modular system. Storage is very easy, because only enough chimney components have to be kept ready.
  • the use of fired clay as a material offers the advantage of a relatively low weight with good workability.
  • the positive locking means for. B. in the form of tongue and groove depressions and projections, an increased alignment of the blocks to each other and thus a better fit is achieved in the masonry of the blocks.
  • a multi-pass chimney can also be completed in a particularly simple manner by a single worker.
  • the known casing stones of the prior art for multi-pass chimneys are regularly formed in one piece and consist of concrete, which results in corresponding weight problems. For example, at least two workers or even a hoist are required to move the conventional casing stones, which is effectively excluded by the present invention.
  • a further embodiment of the claimed multiple chimney system is characterized in that at least some of the chimney components used as building blocks are open along at least one side of the casing area except for a contact surface which is provided with the connecting or form-locking means.
  • the removal of a side region of the chimney component to produce an open side can then - if desired - advantageously on site respectively.
  • the use of unilaterally open blocks ensures an increased saving of space, which is becoming increasingly important in the construction business.
