The socket of each socket tube is gripped from below by a support ring (6) which is secured by radially projecting support arms to the surface of the enclosing brickwork (1). The support arms are angled at their outer ends. The angled sections are designed to engage in recesses in the face of the enclosing brickwork.

Description

The invention relates to a prefabricated chimney Construction of house fireplaces with the characteristics according to the The preamble of claim 1 and claim 8.

Prefabricated chimney components of the type specified above can of different heights, but mostly have Floor height. When building up the mantle individual coat stones have these at their four corners channels running from top to bottom, through which tie rods pass. The tie rods are with the mantle stones regularly by pouring out the channels firmly connected with cement. The fireplace mantle can also be used as a one-piece shaft with cast-in tie rods be trained. There is a smoke pipe in the jacket appropriate length, which consists of individual pipe sections connected to one another at the end consists. To make prefabricated chimney components of this type flawless to be able to transport and their handling at To ensure installation, the flue pipe needs at least a temporary bracket and attachment in the Coat. For this purpose it is known to pass the smoke pipe through a through this and on the outside to keep the wrapping closed. A Another known solution is the bottom of the To include smoke pipe with a sling and the Fix the sling to the coat. Disadvantageous However, this known brackets is that the connection the smoke pipe with the jacket before putting on the Prefabricated chimney component to the next lower one must, but this solution only at the last moment may take place if the smoke tube slips out should be prevented. This requires careful It is not always possible to work and one Avoid loosening the smoke pipe. They also have to Smoke pipe sections are firmly connected to each other, e.g. through glue or mortar so they don't separate from each other can separate or loosen.

The known solutions described above continue to ensure the transportability of the prefabricated chimney components without damage even in the case three - shell fireplaces, where between the mantle and the Smoke pipe a thermal barrier coating is arranged. This lasts the smoke pipe transversely to its longitudinal axis during transport reasonably firm and centered in relation to the coat, provided that the thermal insulation layer is sufficiently stable. In double-walled fireplaces, in which a heat insulation layer is not present or the smoke pipe with a radial distance is arranged by a thermal barrier coating, however, is required additional measures to the smoke pipe also at the usual horizontal position during transport and during the handling of the prefabricated chimney during assembly centered towards the jacket without lateral displacement hold.

The object of the invention is therefore, prefabricated chimney components to propose the type described at the outset, in which the Smoke pipe during transport and assembly against lateral displacement and slipping held securely is.

According to the invention this is achieved by a prefabricated chimney component Claim 1 or claim 10 achieved.

The invention is based on the consideration that for the centered arrangement of the flue pipe in the chimney jacket too after creating the fireplace - especially for double-walled fireplaces - necessary spacers at the same time can be designed as a transport lock. This Transport lock is designed to ensure that the flue pipe is in the prefabricated chimney component, both sideways and in Axis direction of the fireplace is fixed. The well-known Spacers are not without this function further suitable. So they are as protruding laterally Spring arms formed, the lateral displacement of the Cannot prevent smoke pipe in horizontal position. This also applies to a known embodiment of Spacers with one end between successive coat stones attached and are directed like a leaf spring against the flue pipe (DE 44 18 872 A1) or with a radial inner end the guide frame surrounding the smoke tube are connected (EP 209 815 A2). They are also for securing the Smoke pipe not determined in the axial direction of the chimney and suitable.

According to a first aspect of the invention (claim 1) carries for the axial support of the smoke pipe from its training Socket pipe sections at. Because the support ring reaches under the sleeve of each sleeve pipe section and prevented this causes an axial drop. The protruding to the side Support arms are designed so that they during transport and occurring when handling the prefabricated component withstand lateral forces safely. The support arms are in Recesses in the face of each assigned Cladding stones attached so that each socket pipe section is kept for itself This proves to be special advantageous in cases where the plug connection of the Socket pipe sections (socket / spigot end) essentially for the seal is designed, but little or no Can transmit tensile and / or bending forces.

According to a second aspect of the invention (claim 10) the flue pipe is secured by spacers, which as Support rings are formed and one on each Flue pipe section attached cuff laterally protrude. Take over the axial fixation of the smoke pipe in this embodiment of the invention, brackets that at least with the sleeve of the lowest socket pipe section with one end and the top of the Mantle are connected to its other end. In this Case, the connection of the pipe sections can also as Plug connector designed primarily for sealing be trained. The brackets can be threaded rods be attached to the support rings, for example are screwed in and with their other end with one Support are connected to the upper face of the Coat overlaps and is attached to it. As brackets can also use ropes made of plastic or metal be provided, for. B. on hook, at the bottom Cuff or on the protruding support rings attached and with a certain tension with the top of the cloak are connected.

In both versions of the above Invention remain the support rings or cuffs Support rings in the prefabricated chimney component and act in the created fireplace as a spacer. Even the ones mentioned Mounts, e.g. B. threaded rods or ropes can after Solution, if necessary, on the upper face of the Jacket fixed support in the prefabricated component remain because they do not function the fireplace affect.

1 consists of essentially of several (six in the exemplary embodiment) Sheath stones 1 and a flue pipe 2, which consists of several (in Embodiment two) sleeve pipe sections 3 is composed. The mantle stones 1 have a essential square outer and inner contour and show at their corners from the top to the bottom continuous channels 5 that are aligned. By the aligned channels 5 extend, not shown Tie rods; the channels are described in the introduction Way poured with cement, so that the Chimney jacket forms a closed, manageable unit.

The socket pipe sections 3 are by means of a Plug connection connected in the socket area and sealed. This is due to one of the prior art known designs possible, for example Connection and sealing by means of a Ceramic fiber fabric between the top of the top Socket pipe section and the inner wall of the socket lower sleeve pipe section is compressed. The Connection can also be made by putty or Glue or be made by means of an elastomer ring.

The length of the socket pipe sections 3 is on the length of the Coated stones 1 so that they have the total length of in the embodiment shown in FIG. 1 three coat stones exceeds the length of a socket depth. In the case of FIG. 1 shown embodiment, the socket pipe sections 3 are so arranged that the upper sleeve edge at least approximately in one plane with the top face of one Mantelstein 1 lies. With the length of all the same Socket pipe sections 3 results from the fact that Smoke pipe 2 from the lower end of the prefabricated component around the Protrudes length of a socket depth and into an already assembled corresponding prefabricated component is insertable.

The flue pipe 2 is through in the casing unit Support rings 6 radially and against a downward displacement held axially. Each support ring 6 consists of a ring 7, welded to the four laterally projecting support arms 8 are. The support arms 8 have one of the ring 7 radially projecting section 8a, an angled upward axial section 8b, again radially angled Section 8c and a hook-shaped angled End section 8d. In the in the embodiment Relative position of the sleeve pipe sections 3 shown in relation on the casing stones 1, the axial section 8b is so long that it is at least the height of the sleeve of its The start of expansion on the pipe section corresponds.

The ring 7 encloses the socket pipe section 3 below the sleeve with such sufficient play that even in the An expected axial manufacturing tolerances Expansion of the smoke pipe 2 is not hindered. Of the hook-shaped angled end section 8d is in Recesses 9 in the upper end face of the associated Mantelstein 1 hung. Each support ring 6, the Longitudinal course of the prefabricated component is arranged in the existing mortar layer between the casing stones 1 embedded. The one at the top of the prefabricated component provided support ring 6 can in the recesses 9 pinched and additionally by gluing or mortar be secured. In a modified embodiment (Fig. 5b) is conceivable, however, section 8c To keep the support rings 6 so large that the hook-shaped end 8d each in the channels 5 in the corners of the casing stones 1 can be hung. By pouring out these channels with mortar or cement, fixation takes place at the same time the support rings 6 and separate recesses 9 in the Sheath stones 1 are not required.

The embodiment according to FIG. 2 differs from 1 essentially only in that the smoke tube 2 'with its upper sleeve edge is not flush ends with the upper face of the jacket 1 ', but protrudes by about a sleeve length. This correspondingly applies to those forming the smoke tube 2 ' Socket pipe sections 3, which are located inside the jacket 1 ' are located and accordingly on the parting line between protrude two adjoining coat stones.

In the exemplary embodiment according to FIG. 2, the length is Socket pipe sections 3 to the length of the casing stones 1 ' so tuned to the total length of five here Mantle stones exceeds the length of a socket depth.

That protruding beyond the top of the jacket 1 ' Smoke tube 2 'is against an axial displacement upwards by a support 4 in the form of a cranked bracket held with both ends in openings of the Jacket 1 'is screwed tight. In the shown Embodiment are the openings through two diagonally opposite channels 5 are formed, through which the - Not shown - extend tie rods through.

2 are due to the different relative arrangement of smoke pipe 2 ' Sheath 1 'support rings 6' required by the central Have ring 7 'made of radially extending straight support arms 8' (Fig. 6). These support rings 6 'can, as shown in FIGS. 5a, 5b emerges in separate recesses of the Top of the jacket 1 'or suspended in the channels 5 be. Between the two limit positions that the smoke pipe 2 in relation to that formed by the casing stones 1 Fireplace mantle occupies, that means this above or below protrudes (Fig. 1, 2), intermediate layers are also conceivable in which the smoke pipe 2 above and below from the chimney jacket protrudes. This is achieved by designing the support rings 6 or 6 'taken into account in that their support arms 8 or 8 'are angled correspondingly less or at an angle run.

Since the embodiments according to FIGS. 1 and 2 are double-shell prefabricated chimney components, one is required radial support of the socket pipe section 3 on the lower End of the prefabricated component. This support can be provided by a Support ring 6 can be reached in to the existing Tragrings 6 in the opposite direction, d. H. with after support arms 8 angled at the top of the Socket pipe section 3 plugged in and in corresponding - not shown - recesses 9 in the lower End face of the lowest cladding stone 1 or 1 'or in whose channels 5 is inserted. It is also possible to get one Support ring 6 or 6 'in the parting line between the lowest and the next cladding stone 1 or 1 ' fasten. In the exemplary embodiments shown, the lateral support of the socket pipe section 3, however realized by a spacer that is more common Can be of construction or has a design that below in connection with the embodiment according to Fig. 7 is described.

The embodiment according to FIG. 7 differs from that according to FIGS. 1, 2 by the different Type of fixation of the smoke pipe 2 in the casing stones 1 and in that the sleeve pipe sections 3 by glue or mortar are connected to each other with tensile strength. For this There is no need for a more detailed explanation here Explanation of the structure.

There is one on each of the socket pipe sections 3 Spacer sleeve 10 clamped (Fig. 8), the tensioned by means of a lever quick-release fastener 11 or can be solved again. On the cuff 10 are in equal angular distances four approximately part circular Bracket 12 welded, the laterally protruding support rings form. The cuff 10 and the support rings 12 are made made of sheet metal; the material thickness is chosen so that the Support rings 12 which with horizontal storage of the Finished component loads caused by the weight of the flue pipe 2 and without knocks Can take over deformation. An adaptation of this Support structure to different diameters of the Flue pipe 2 or the casing stones 1 is through a Change in length of the cuff 10 forming Sheet metal strip possible, the size of the support rings 12th forming bracket can remain essentially the same.

The support rings 12 have holes 14 at the top and bottom, in which with threaded rods 16 in the embodiment hooked angled ends 17 are hooked can. The threaded rods 16 extend axially one on the upper end face of the uppermost casing stone 1 attached support 18 in the form of a plate and penetrate holes 19 provided in plate 18. By nuts 20 on the upper end of the threaded rods 16 are screwed on, a tensile force on the Cuff 10 and over this to the socket pipe section 3 are exercised so that this is shown in Fig. 2 Axial position is held on the plate 18. With this Embodiment it is necessary that the Socket pipe sections 3 sufficient with putty or mortar are firmly connected so that the whole Smoke tube 2 in itself and be sustainable Slipping out down through the threaded rods 16 is avoided.

By using socket pipe sections for that Smoke pipe and the resulting resulting described Excess of the smoke pipe at the upper and / or lower end the chimney jacket is the assembly of the invention Prefabricated chimney component relieved. Because inserting the lower smoke pipe end of the prefabricated chimney component to be moved into the upper end of the smoke pipe staggered chimney prefabricated part already takes place When the crane lets it down, at which time the each chimney jacket still a sufficiently large Have a distance from each other, so that the insertion optically can be monitored. Since the smoke pipe due to the Game with which it is received in the support rings 6, 6 ' or the support rings 12 from the chimney jacket inner wall can keep to the side to a certain extent, it becomes in the course of further lowering the prefabricated chimney component from the socket of the prefabricated chimney component guided. The insertion process then runs automatically. This proves particularly in the case of two or multi-pass chimney prefabricated components as considerable Advantage.
