Abstract
Description
[0001] The invention is based on an arrangement of a chimney device in a building, designed as follows: a) that the chimney installation comprises a chimney and a fireplace, b) that the chimney has an outer casing made of bricks or pipes and a flue pipe arranged therein; c) that the chimney has a longitudinal reinforcement formed by reinforcing bars which are fixed axially through the outer shell in or on the outer shell, preferably in cast-in receiving channels; d) that the chimney has a lower chimney support and an upper chimney support, which engage the chimney in a lower and an upper section, respectively, to support horizontal forces. The chimney is a rigid chimney.
[0002] Such arrangements are known from corresponding chimney products on the market, e.g., the product of the applicant ERLUS AG: ERLUS LAF Premium Chimney (ERLUS CE system description according to ETA 11 / 0271 for LAF Premium Chimney). This is a rigid chimney mounted on the floor of a building with a separate fireplace positioned at a distance from the chimney on the floor of the building. The fireplace has a separate body. The flue pipe from the fireplace is connected to a nozzle located laterally in the lower section of the chimney. The chimney has an outer casing made of concrete blocks.
[0003] The familiar chimney features longitudinal reinforcement, which is formed in the outer casing by structural steel bars in cast corner channels of the casing bricks. The chimney has a lower chimney support, which is attached to the floor of the building and engages the outside of the lower casing brick to absorb horizontal forces. The upper chimney support is formed by the roof opening of the chimney, with the outer casing of the chimney extending through the opening in the roof. This familiar chimney system with a rigid chimney is relatively complex in its construction and assembly.
[0004] Document DE 195 37 373 A1 describes a chimney with longitudinal reinforcement anchored in a special casing brick. The chimney extends through the roof with its upper section and a floor slab with its lower section.
[0005] Document DE 88 08 130 U1 describes a ceiling slab for a shaft structure with fastening to the shaft wall via angle elements.
[0006] The invention is based on the object of creating a chimney device with a rigid chimney that is simple in construction and allows easy assembly.
[0007] The problem is solved with the subject matter of main claim 1.
[0008] This is the arrangement of a chimney in a building. This application requires that the chimney system includes a chimney and a fireplace.
[0009] The fireplace is preferably located separately outside the chimney. Designs are also possible in which the fireplace is integrated into the chimney, i.e., located in the lower part of the chimney in the chimney base.
[0010] The structure of the chimney provides that the chimney has an outer shell made of casing stones or pipes and an exhaust pipe arranged therein.
[0011] It is essential for the flexural rigidity that the chimney has a longitudinal reinforcement formed by reinforcing bars that are fixed axially through the outer shell in or on the outer shell, preferably in cast receiving channels.
[0012] Furthermore, in connection with the flexural rigidity, it is essential that the chimney has a lower chimney support and an upper chimney support, which engage the chimney in a lower and an upper section respectively to support horizontal forces.
[0013] The solution according to the invention provides that the chimney is supported on a floor of the building, preferably on a floor slab, in that the chimney has a base plate at its lower end that rests on the floor of the building. The base plate is an essential feature of the invention. It is essential that the longitudinal reinforcement is anchored in the base plate at its lower end by anchors being concreted into the base plate and that the reinforcing bars of the longitudinal reinforcement are coupled to the anchors at the lower end of the longitudinal reinforcement, either directly or indirectly via coupling elements. The base plate is preferably made of dense concrete, preferably fiber concrete, in particular glass fiber concrete. In contrast, the casing stones that form the outer casing are preferably made of lightweight concrete, preferably porous lightweight concrete.This means that the casing stones are preferably made of lightweight concrete, while the base plate is preferably made of normal concrete.
[0014] The base plate can serve multiple functions. It can support the outer casing of the chimney, while also providing an anchoring point for the chimney's longitudinal reinforcement. Another important function of the base plate is supporting horizontal forces. In this context, the invention provides for the lower chimney support to have an angle device that has at least one horizontal leg that is fixedly supported on the floor of the building, and at least one further, preferably vertical leg that engages the base plate to support horizontal forces.
[0015] The engagement of the vertical leg means that the vertical leg interacts directly with the base plate, e.g., as a stop to support horizontal forces. There may be some play between the vertical leg and the stop surface of the base plate. The vertical leg is preferably not fixed to the base plate by means of a fixing element.
[0016] Preferably, it can be provided that the angle device of the lower chimney support is designed as an angle frame that is placed over the base plate and surrounds it or is formed by individual L-angles that are arranged around the base plate.
[0017] As far as the upper chimney support is concerned, it can be provided that the upper chimney support is formed by a passage through a roof of the building or by a passage through an upper floor ceiling, in that the chimney with its outer casing passes through a passage opening in the roof or in the upper floor ceiling of the building and the outer casing interacts with the passage opening to support horizontal forces.
[0018] Different basic designs of chimney systems can be realized, namely chimney systems in which the fireplace is arranged next to the chimney, preferably on the floor of the building, on which the chimney is also supported by the floor slab, and other chimney systems in which the fireplace is arranged below the floor on which the chimney is supported.
[0019] The first-mentioned basic designs, which provide for the fireplace to be arranged upright next to the chimney on the floor of the building, can advantageously provide for an intermediate plate, positioned vertically above the floor plate, within a space surrounded by the outer casing, on which the exhaust pipe is supported at its lower end. This intermediate plate can preferably be made of lightweight concrete, the same material as the casing stones. In contrast, the floor plate is preferably made of standard concrete, preferably dense concrete, in particular fiber concrete, particularly preferably glass fiber concrete.
[0020] In these first-mentioned basic designs, it can be provided that a preferably annular and / or conical support element rests on the intermediate plate to support the exhaust pipe on the intermediate plate. Its upper end engages a projection on the outside of the exhaust pipe, preferably a sleeve, engaging behind the exhaust pipe. The support element can be designed as a ceramic support element.
[0021] In the second-mentioned basic designs, which provide that the fireplace is arranged below the floor and that the exhaust pipe with its lower section extends through a through opening in the floor and is connected with its lower end to the fireplace, it is preferably provided that the floor plate has a through opening and is arranged on the floor in such a way that the through opening of the floor plate is aligned with the through opening in the floor and the exhaust pipe extends through the two aligned through openings.
[0022] In these second-mentioned basic designs, the exhaust pipe is advantageously supported on the floor slab. For this purpose, the exhaust pipe can be supported on the floor of the building via the floor slab by a preferably annular and / or conical support element resting on the floor slab, the upper end of which engages a projection on the outside of the exhaust pipe, preferably a sleeve, engaging behind the exhaust pipe. The support element can be designed as a ceramic support element.
[0023] In the different basic designs, the lower chimney support can be provided to support horizontal forces, the angle device of the lower chimney support can be designed as an angle frame that is placed over the base plate and surrounds it, or it can be designed as individual L-angles that are arranged around the base plate.
[0024] In both basic designs, anchors are cast into the base plate to connect the structural steel bars of the longitudinal reinforcement, which penetrate the casing stones in cast receiving channels.
[0025] In the basic design with an attached fireplace, an intermediate plate is arranged between the lower casing stone and the casing stone above to support the exhaust pipe. The intermediate plate is penetrated by the structural steel bars of the longitudinal reinforcement in the same way as the casing stones, preferably in cast-in channels that are aligned with the channels of the casing stones.
[0026] Preferably, it can be provided that the upper chimney support is formed by a passage through a roof of the building or by a passage through an upper floor ceiling, in that the chimney with its outer casing passes through a passage opening in the roof or in the upper floor ceiling of the building and the outer casing cooperates with the passage opening to support horizontal forces.
[0027] In the various designs, the exhaust pipe can be constructed from socket pipes. The exhaust pipe can be provided with an insulating jacket. The exhaust pipe can be designed as a ceramic exhaust pipe.
[0028] As for the outer casing, the chimney's outer casing may be constructed of concrete material, preferably concrete casing blocks. The lower casing block of the outer casing may have notched recesses in the corner areas to accommodate connecting couplings for the longitudinal reinforcement.
[0029] The longitudinal reinforcement may preferably consist of structural steel bars which are accommodated in cast vertical receiving channels in the casing stones.
[0030] In preferred embodiments, the longitudinal reinforcement can be formed from structural steel bars, each of which extends through cast-in receiving channels through storey-high chimney sections. The storey-high chimney sections can easily be arranged one above the other on site, and the structural steel bars of the longitudinal reinforcement of the storey-high chimney sections mounted one above the other can be coupled via coupling elements. For this purpose, the lower casing brick of the upper chimney section can be notched in each corner area. The structural steel bars of the longitudinal reinforcement of the upper chimney section protrude into the notch with their lower ends, and the structural steel bars of the longitudinal reinforcement of the lower chimney section protrude into the notch with their upper ends. These opposite lower and upper ends of the structural steel bars are each coupled in the notch via a coupling element.
[0031] The invention is described in more detail below with reference to the drawings. These show: Fig. 1 a first embodiment in schematic side view, partially sectioned, Fig. 2 a sectional view in Fig. 1 in the area of the lower section of the chimney, Fig. 3 a cross-sectional view of the chimney in Fig. 2, Fig. 4 a detailed view in Fig. 2 in the area of a notch in the lower casing stone, showing the longitudinal reinforcement with coupling element and anchor in the base plate with the angle frame doweled in the floor slab, Fig. 5 a Fig. 2 corresponding sectional view of another embodiment, Fig. 6 a Fig. 3 corresponding cross-sectional view of the chimney in Fig. 5.
[0032] In the Fig. The embodiment shown in Figures 1 to 4 is a chimney device comprising a chimney 1 and a fireplace 2. The chimney 1 is supported on a floor 3 of a building.
[0033] The chimney 1 has an outer casing 1m and a flue pipe 1r arranged therein. The outer casing 1m is constructed of concrete casing blocks 1mi. The flue pipe 1r is constructed of ceramic socket pipes 1ri. The ceramic socket pipes 1ri each have an insulating casing 1rd that surrounds the socket pipes 1ri from the outside.
[0034] The chimney 1 is supported with its lower end on the floor slab 3. The exhaust pipe 1r extends through a through-hole 3d formed in the floor slab 3. A base plate 4 is provided to support the chimney 1. The base plate 4 has a through-hole 4d. The base plate is arranged on the floor slab 3 such that the through-hole 4d of the base plate 4 is aligned with the through-hole 3d of the floor slab 3. The chimney 1 rests with the lower edge of the outer casing 1m on the base plate 4. The exhaust pipe 1r extends with its lower end section through the through-hole 4d of the base plate and the through-hole 3d of the floor slab. The lower end is designed for connection to a fireplace 2 installed in the floor below the floor slab 3. The fireplace 2 is in Fig. 1 shown schematically.
[0035] The exhaust pipe 1r, which thus passes through the floor slab 3, is supported on the base plate 4 via a preferably ceramic support element 5. In the illustrated embodiment, the support element 5 is designed as a conical support ring, which rests with its lower wide end on the base plate 4 and engages with its upper narrow end on the socket of the lower socket pipe 1ru, which passes through the floor slab 3.
[0036] The lower socket pipe 1ru, supported by the support element 5, extends with its pipe section through the through hole 4d in the base plate 4 and the aligned through opening 3d in the floor slab 3. An insulating shell is interposed. It extends radially in the passage over an axial length formed by the axial length of the through hole 4d and the axial length of the through opening 3d. The entire exhaust pipe 1r arranged above it, which consists of nested socket pipes 1ri, is supported in the thus supported lower socket pipe 1ru. The exhaust pipe 1r discharges at the upper end of the chimney 1.
[0037] The base plate 4 forms a floor slab, i.e., it rests on a floor of the building, in the illustrated case on the floor slab 3. The base plate 4 forms a bearing plate for the outer casing 1m of the chimney 1. It also forms a support and centering element for the ceramic flue pipe 1r. In addition, the base plate 4 forms an anchoring plate for a longitudinal reinforcement 6 of the chimney and a support for a lower chimney bracket 10u, as described below.
[0038] As mentioned, the chimney has longitudinal reinforcement 6 and is supported by two brackets 10u, 10o in the building. The brackets interact with the chimney 1 to absorb horizontal forces. The lower bracket 10u is formed in the area where the chimney 1 is supported on the floor slab 3. The upper bracket 10o is formed in the area of the roof opening. Therefore, the chimney 1 extends with its outer casing 1m through the opening 8d in the roof 8, so that the outer casing 1m interacts with the opening 8d to support horizontal forces.
[0039] The lower bracket 10u is formed by securing the base plate 4, in which the longitudinal reinforcement 6 is anchored at its lower end via anchors 4f cast into the base plate 4, by an angle frame 7. The angle frame 7 is placed over the base plate 4 such that the angle frame 7 surrounds the base plate 4. The angle frame 7 is a substantially rectangular or square frame with a lower horizontal leg and an upper vertical leg. The lower horizontal leg is anchored to the floor slab 3 via dowels 7f. The upper vertical leg is adjacent to the vertical butt side of the base plate 4 and thus absorbs horizontal forces.
[0040] The longitudinal reinforcement 6 consists of structural steel bars 6s, which are cast in corner channels 1e in the casing blocks 1mi, 1mu. At their lower ends, the structural steel bars 6s are connected to the anchors 4f, which are concreted into the base plate 4. A coupling element 6k with clamping screws is arranged between the lower ends of the structural steel bars 6s and the anchors 4f. For this purpose, the lower casing block 1mi has notches 1ma in the corner areas. The notches 1ma form receiving spaces into which the lower ends of the structural steel bars 6s engage. A coupling element 6k with clamping screws is arranged in each receiving space, which couples the lower ends of the structural steel bars 6s to the anchors 4f concreted into the base plate 4.
[0041] In the illustrated embodiment, the anchors 4f and the coupling elements 6k embedded in the base plate 4 are designed as follows:
[0042] The anchor 4f has a connecting stub as its connecting end, which is firmly screwed into an internally threaded sleeve in the anchor housing. The anchor 4f is concreted into the base plate 4 in such a way that the free connecting end of the connecting stub protrudes freely.
[0043] The coupling end 6k has two terminal-type connection ends. Each of these connection ends is designed as a tubular connection bushing with two transversely arranged threaded holes for receiving clamping screws. The bush-shaped connection end is designed to accommodate the stub end of the structural steel bar 6s of the longitudinal reinforcement 6 or the connection stub of the anchor 4f.
[0044] In modified versions, a bracket made of separate angle elements, preferably L-shaped angle elements, can be used instead of the angle frame 7. The angle elements are arranged and anchored around the base plate 4 in a similar way to the angle frame 7.
[0045] The Fig. 5 and Fig. 6 show a further embodiment. In this embodiment, in contrast to the embodiment of the preceding figures, the fireplace 2 is not arranged below the floor slab 3, but on the same floor slab 3 as the chimney 1. The chimney has a base plate 4o. The outer casing 1m is supported on the base plate 4o. The outer casing 1m is also formed by casing stones 1mi. The lowest casing stone 1mu rests on the base plate 4o. The exhaust pipe 1r leads from the fireplace 2 to the chimney 1 and opens laterally into the second lowest casing stone 1mi. An intermediate plate 400 is arranged between the lowest casing stones and the casing stone 1mi arranged above. It has a through hole. It separates the space formed by the shell walls 1mu and 1mi into a lower cavity, which forms a base with condensate drain, and an upper space in which the exhaust pipe 1r is arranged.
[0046] The exhaust pipe 1r is supported on the intermediate plate 400. As in the embodiment of the preceding figures, a corresponding conical support ring 7 is provided for this purpose. This ring rests on the intermediate plate 400 and engages with its upper edge on the socket of the lower socket pipe. The longitudinal reinforcement is anchored in the base plate 4o, as in the previous embodiment. For this purpose, corresponding anchors are concreted into the base plate 4o, to which the reinforcing bars are coupled with their free ends at the bottom via a coupling piece.
[0047] In both illustrated embodiments, the fireplace 2 is designed separately from the chimney 1, is arranged outside the chimney and is supported separately. In the embodiment of the Fig. 1 to 4, the fireplace 2 is arranged below the floor slab 3 on which the chimney 1 is installed. In the embodiment of the Fig. 5 and Fig. 6, the fireplace 2 (not shown) is provided, meaning that the fireplace 2 and the chimney 1 are installed on the same floor 3. Each fireplace has its own separate body. The fireplace 2 can be designed as a convection fireplace or a storage fireplace, or as a combination of both.
