Such expansion joint coverings are in the upper End areaj the head area, of the chimney inserted into the smoke pipe, if the chimney has a Has smoke pipe surrounding insulating layer within a jacket pipe. The insulating layer is known required to cool the chimney too much uiiu uatiixt / uci fiugaoc Zu vcxmciuuuj um cxucu guucii υυιιυιιι ~ to ensure stone pull. The cooling of the flue gases inside the flue pipe must also be avoided, in order to avoid falling below the dew point and thus the formation of acid.

Ine expansion joint is provided which is covered by the inner tube of the expansion joints panel, can so that flue gases and moisture does not get into the adjoining the expansion joint insulation layer ^';: due to the thermal linear expansion of the flue pipe is at the upper front ^end>. The insulating layer is covered at its upper end by the flange plate, the outer edge of which is located inside the jacket tube.

The invention has for its object to improve the elongation \ joint fillet, so that moisture from the flange plate located above the flue pipe and the insulating layer can not be discharged into the masonry of the jacket tube, so that also protected from this side, the insulating layer against moisture penetration is. Condensate formed in the chimney head should therefore be able to be retained with certainty within the flange plate area in the jacket pipe.

According to the invention, this object is achieved in that a bead surrounding the inner tube and maintaining a distance from it is incorporated into the flange plate along a closed line. If the bead emanating from the bottom of the Planschblechs, the Planschblechs arises at the top a condensate droplets from αθί. "Circumferential bead limited outwardly and falling from the inner tube inwards limited annular evaporating dish. Falling rain water or downgrades Γ ~) from the flue gas collect

are on the outside of the upper end of the inner tube and run from there into the evaporation tray or they fall from their place of origin into the evaporation dish. As a result of the increased temperature you can they evaporate there immediately and escape from the chimney head to the outside, so that there is no danger, that moisture over the outer edge of the flange plate into the masonry of the jacket pipe and from there gets into the insulating layer.

When the paddling plate is turned by 180 ° and is attached to the inner tube, so that the circumferential bead to > - 'Top of the flange plate is open, so offers

they have a receiving space for a sealing material, which rests against a head plate located above it, so that the jacket pipe is sealed off from the smoke pipe. A circumferential sealing ring formed in this way, for example made of acid cement ₃ , also prevents moisture from penetrating to the outer edge of the flange plate, which is located within the masonry of the jacket pipe. Even with this arrangement of the paddling plate, it is therefore not possible that on the way over the outer edge of the paddling

The closed line of the circumferential bead can preferably be a circle _5, which is suitable for chimneys with circular cross-sectional smoke pipes.

Preferred embodiments of the invention are contained in the protection claims * The scope of protection extends not only to the claimed individual features , but also to their combination.

The expansion joint lining according to the invention is composed of an inner pipe 10 ₃ bent from sheet metal, which is arranged in the chimney in the vertical direction, and a horizontal flange plate 11 fastened to the outer circumference of the inner pipe 10.

Excessive cooling of the flue gases so that condensation droplets formed here cannot get into the insulating layer 14 because they are retained by the inner tube 10.

The upper annular end face of the insulating layer 14 is prevented from penetrating with the help of the flange plate 11 protected from moisture, which is at a certain height on the outer circumference of the inner tube 10, is consolidated. The attachment is done in that

the inner tube 10 has a profiled jacket and the flange plate 11 with its angled inner edge 21 in a profiled groove of the inner tube intervenes.

That which runs at right angles to the axis of the inner tube 10, that is to say in the case of inner tubes 10 with a circular cross-section radially extending flange plate 11 is provided with a bead 22 which extends along a closed line extends around the inner tube 10 at a distance from the inner tube 10. According to Fig.l of the drawing the bead 22 runs in the area of the inner wall of the jacket tube 12 or the flow head 15. Here is the

Bead 21 opens downwards so that there is one after Annular evaporation dish 2 3 of the flange plate 11, which is open at the top, results. For chimneys with a rectangular cross-section the annular evaporation tray 23 is also rectangular, while it is in chimneys forms a circular ring with a circular cross-section. Above the smoke pipe 13 and the insulating layer liquid droplets located, for example rain penetrating into the flow head 15 or rain formed here Condensate droplets get from the smoke pipe

thus when they fall outside the inner tube 10 into the evaporation tray 23, where they can evaporate due to the increased temperature of the paddling plate 11 due to the hot smoke gases flowing out. The heating of the splash plate can take place as a convective heat transfer from the lower region of the inner tube 10. The bead 22 thus prevents moisture can be derived from the flange plate 11 toward the outer edge, which is located within the ζ ~ \ masonry of the casing tube 12th

In the embodiment according to FIG. H of the drawing, the flange plate 11 is arranged with its bead 21 on the inner tube 10 turned by 180 °, so that the bead 22 running at a distance around the inner tube 10 along a closed line opens up here is. This results in a receiving space for a sealing ring 24, which is arranged between the flange plate 11 and the head plate 17 arranged above it. The sealing ring 24 prevents the penetration of moisture from the smoke pipe 13 into the mortar 25 of the masonry of the jacket pipe 12, so that the insulation arranged below the flange plate 11 also

layer 14 is protected in this way from the ingress of moisture. As a material for the For sealing ring 24, an acid cement can be used.
