Definitions

  • the invention relates to a chimney cover element for covering the chimney head of a brick chimney or a chimney made of chimney elements except for a flue gas passage opening, and to a chimney cap connected to a chimney cover element.
  • the object of the present invention is, in particular, to provide a chimney cover element which replaces these conventional cover plates and which does not have the aforementioned disadvantages.
  • a chimney cover element of the type mentioned at the outset in that this cover element has a thermal insulation part which covers the upward-facing end face of the chimney head but leaves the flue gas passage opening and which consists of thermal insulation material and which is seen on its top and in the horizontal direction inside - And outside is surrounded by a water-impermeable sheathing, that this sheathing delimiting the flue gas passage opening consists of metal and is not heat-conducting and thereby interrupting the cold bridge, is firmly connected to the rest of the sheathing.
  • the inside for example by means of temperature and exhaust-resistant silicone rubber, is not connected in a heat-conducting manner to the downward-facing side of the top of the casing, so that the inside, which is swept by the exhaust gas flowing through it, does not cool down from the remaining cold part of the casing can be.
  • the part forming the inside of the casing is formed by an expansion joint collar which extends downward in its axial direction beyond the thermal insulation part.
  • the expansion joint collar extends upwards in its axial direction beyond the thermal insulation part, and that part of the expansion joint collar which extends upward beyond the thermal insulation part is surrounded on the outside by a thermal insulation material. It is also expedient if the underside of the thermal insulation part rests on a frame, net or perforated mounting part connected to the casing, and the latter preferably consists of poorly heat-conducting material or is connected to the upper and outer side of the casing via such.
  • the chimney element is designed in such a way that, when arranged on the chimney head, at least a part of the thermal insulation part is in air circulation connection with the outside atmosphere.
  • the sheathing consists of a copper alloy or chromium-nickel steel.
  • this chimney cover element is provided on its outside with a drip plate which laterally projects beyond the chimney head and extends downward.
  • the chimney cover element according to the invention is to be used for a rear-ventilated chimney, then it is expedient if it is provided with spacing means for forming at least one ventilation slot which extends radially and extends into the outside atmosphere between its underside and the upward-facing end face of the chimney head to be covered is provided (Fig. 1).
  • the chimney cover element according to the invention is to be used for a normal chimney without rear ventilation. then it is advantageous if its underside is designed to rest on the upward end face of the chimney and projects radially outward from this end face, and that at least this part of the underside, which is intended to protrude laterally from the end face of the chimney, is air-permeable is formed (Fig.2).
  • the inside of the casing is connected to the latter via a temperature-resistant silicone rubber, preferably with the surface of the casing facing downward, so that the cold bridge is reliably interrupted.
  • the present invention also relates to a chimney cap with a chimney covering element forming an integral part of the chimney covering element according to one of claims 1 to 11. It is advantageous if the chimney cap is connected to the chimney covering element by means of heat-insulating means that interrupt the cold bridge.
  • this chimney cap with a pipe socket, an inner jacket arranged at least approximately in the shape of a truncated pyramid, which extends coaxially with the latter, and a pipe socket arranged coaxially with the latter, projecting above the inner jacket and distanced from it to form an annular chamber
  • Outer jacket which has at least approximately the shape of the lateral surface of a regular prism or a truncated pyramid, is provided, and preferably at least one through-flow opening is provided in at least some of the surfaces forming the inner and / or outer jacket.
  • the chimney cover element 2 provided for covering the chimney head of a brick chimney 1 ventilated via the channels 0 has the upwardly directed end face of the chimney Chimney head covering, consisting of highly thermally insulating thermal insulation material 3, which is surrounded on its upper, inner and outer side 4,5 and 6 respectively by a water-impermeable casing 7.
  • the inside 5 of the casing 7 is formed by an exhaust gas-resistant expansion joint sleeve 10, which extends in its axial direction beyond the thermal insulation part 3 down into the chamotte tube.
  • the top and the outside 4 and 6 of the casing 7 consist of an approximately 1 mm thick copper sheet.
  • the expansion joint collar 10 is firmly connected to the downward-facing surface of the upper side 4 of the casing 7 by means of a temperature-resistant silicone rubber layer 28 in order to avoid any cold bridge, and thus cannot be cooled by the cold outside air, since it is located inside the casing in this way.
  • the underside of the thermal insulation part 3 lies on a mesh 8 connected to the casing 7, which consists of poorly heat-conducting material such as nylon.
  • the cover element 2 On its outside, the cover element 2 is provided with a drip plate 9 which laterally projects beyond the chimney head and extends downward.
  • the chimney cover element shown on the inside has an expansion joint sleeve 10 which is insulated against cold bridges and which engages in a chamotte tube 11.
  • the fireclay tube 11 in turn is surrounded by a heat insulation layer 12 and this in turn is surrounded by a casing block 14 provided with ventilation channels 13. After that follows the wall 15 and the exterior plaster 16.
  • the cover element is designed to be stepped upwards against the expansion joint collar 11.
  • the cover element lies on the chimney casing, forming ventilation ducts 17 which extend in the radial direction from the inside to the outside.
  • the grating 8 can, for example, be correspondingly corrugated in this area. In this way, the air serving for rear ventilation and flowing through the vertically extending channels 0 to the outside via the horizontally extending ventilation channels 17 can escape to the outside or reach the decentralized fireplaces.
  • the chimney itself can be, for example, like that from the company Schiedel GmbH. & Co., Kunststoff, the Schiedel insulating chimney type SIH provided with ventilation.
  • the expansion joint collar 10 which is made of a chromium steel alloy, is a good heat conductor and cannot be cooled by external parts of the chimney cover element via cold bridges, any undesirable ice formation on the expansion joint collar is avoided and at the same time the insulation 3 is absolutely dry and thus, thanks to the latter, even the outlet area of the chamotte tube 11 and the expansion joint collar 10 kept at the desired temperature.
  • the chimney cover element 2 is connected to a chimney cap 18 via a heat-insulating connection (not shown) to form a single unit.
  • This chimney cap is provided with an approximately truncated pyramid-shaped inner casing 19 which is arranged coaxially to the pipe socket as an expansion joint sleeve 10 and which projects above this pipe socket 10, and with a coaxial to the latter, which projects above the inner casing 19 and forms an annular chamber 20 therefrom distanced outer jacket 21, which is also approximately truncated pyramid.
  • the surfaces forming the inner and outer shells 19 and 21 are, for example, from the not previously published CH -Patent No. (CH-Patent application No. 2103 / 87-8) known, flow openings 22 are provided, to which flow deflection flaps 23 are assigned.
  • the cover element with its grid-shaped underside is on the upward-facing end face of a conventional, not ventilated chimney placed directly.
  • the dry insulation or rear ventilation of the thermal insulation material 3 is achieved in that the part of this thermal insulation material 3 projecting laterally beyond the end face of the chimney via the grille 8 and the annular space which is open at the bottom and is formed between the outside of the wall 15 and the inside of the drip tray 9 24 communicates with the outside atmosphere.
