Definitions
- the invention relates to a module and a jacket made of such modules, as described in the preamble of claims 1 and 28.
- a stove tile for forming a tile assembly for tiled stoves which is a one-piece body of uniform material and there are only small remaining gaps, which results in uniform heat conduction.
- Grooves encircling the face of the stove tile enable a tile structure of high stability to be built up quickly by means of so-called gussets inserted into the grooves as connecting elements, the grooves being filled with clay mortar.
- a disadvantage of such stove tiles is the edge formation in a tile structure and the insufficient stability in stove ceilings formed with such stove tiles and in the area of an operating opening.
- a plate-like element for producing the outer structure of a tiled stove or a fireplace is also known, in which at least a portion of each of the peripheral edge regions has a shape for receiving detachable connecting links, these receptacles also being formed by pocket-shaped grooves which are formed at least in one section or grooves extending over the entire length of the end faces. Connectors with a press fit can be inserted into these grooves, thus achieving a high resistance to wall dressings.
- Such a design requires a large number of special forms of modules in order to be able to form all the connection areas and transitions that occur.
- the object of the invention is now to create a building block made of refractory material, with which a highly variable construction of a heating device is made possible and which enables a permanently firm connection in the wall structure as well as in the corner structure of the walls as well as walls and ceiling.
- a grid-like arrangement of recesses which extend from the inner surface into the building block, in conjunction with grooves running all around, enables a high degree of combination and simple connection of the building blocks in a flat wall bond as well as in planes running at right angles to one another or also at building blocks or wall and / or ceiling elements offset at an angle to one another are possible.
- the formation of the recesses, which only extend over a partial area of the inner surface, also achieves a building block of high inherent strength, and premature destruction due to the occurrence of cracks due to thermal stresses is effectively avoided.
- the recesses enlarge the inner surface of the building blocks, as a result of which the building block is rapidly warmed, in particular when such a heating device is put into operation, and the heat is radiated very quickly to the surroundings, as a result of which overall Efficiency of such a heater is improved.
- the advantageous developments described in claims 2 to 11 achieve a high number of design options for the recesses, which enable the use of specially shaped connecting elements and thus ensure rapid assembly, firm cohesion and also disassembly for repair measures.
- the taper of the recesses also simplifies a molding process of the building blocks, be it in the casting process or a dry pressing process, and a complicated structure of molds and tools is avoided.
- the formation of the recesses is designed so that excess connecting means introduced into the recesses, e.g. Glue, mortar, etc., can be pressed out when inserting the connecting elements to produce a positive fit.
- Formations according to claims 12 to 15 are also advantageous because they are high Strength of the building blocks is achieved and cracking or destruction of the building blocks under the high temperature load to which these building blocks are exposed is avoided.
- Formations according to claims 20 and 21 are also advantageous because this achieves a high degree of dimensional accuracy for the building blocks, which ensures a high degree of possible combinations for arranging the building blocks with respect to one another, and furthermore avoids sharp-edged transitions into recesses, grooves and recesses which tend to crack become.
- a high stability of the connection is achieved by springs inserted into the grooves between adjacent components, but also a sufficiently high strength of the springs for superimpositions is achieved in order to e.g. for openings in the wall parts.
- the object of the invention is, however, also to provide a jacket for a heating device, in particular a tiled stove, which can be designed with one or two shells, if necessary, and which enables a heater to be installed quickly and easily.
- Formations as described in claims 29 to 37 are also advantageous, whereby the building blocks can be put together to form a jacket for a heating device without additional support and formwork elements, and a high strength of the structure is achieved and commissioning of such a heating device can be carried out immediately after the completion of the building.

- the combustion chamber 4 On a substructure 2, which is supported on a contact surface 3 and e.g. consists of masonry, the combustion chamber 4 is provided with smoke flues 5, which flow-connect the combustion chamber 4 with a smoke outlet 6, e.g. formed a two-shell structure.
- the combustion chamber 4 is formed by building blocks 7, which are made of refractory material, with subdivisions for the flues 5 optionally being formed with building blocks 7.
- Upstream of the block 7 is a furnace jacket 8 which e.g. is formed from glazed tiles 10 on outer surfaces 9, which are in good thermal connection with the building blocks 7.
- the tiles 10 are designed for the optical design of the heating device 1 with an optional design.

- the building blocks 7 are provided with grooves 14 on end faces 13 and have bores 16 arranged on the outer surfaces 15 facing away from the combustion chamber 4 and serving to arrange a connecting device 17.
- a connecting device 17 By means of such a connecting device 17, a permanent and firm dressing is achieved overall, which, however, can also be easily broken down in the event of repairs.
- the building blocks 7 made of refractory material can also be used for a heating device 1, which is formed from single-layer building blocks 7, which is plastered on the outer surface 9, as is known from prior art for such heating devices 1 , is provided.
- the block 7 is shown in FIGS. 2 and 3. This has a cuboid shape with a thickness 18, a height 19 and a length 20, the height 19 and the length 20 corresponding to an integer multiple of the thickness 18.
- the grooves 14, which run along a bisector 21 of the thickness 18, are arranged in the end faces 13 delimiting the block 7 in its height 19 and its length 20.
- the inner surface 24 and the outer surface 15 and the side flanks 25, 26 of the groove 14 facing them have the same size and correspond to the thickness 18 minus half a width 27 of the groove 14.
- a depth 28 of the groove 14 is greater than the width 27 and is approximately 1.5 times the value of the width 27.
- Recesses 34 are arranged in the inner surface 24 of the block 7 in the area of interfaces 32 of the delimiters 29 and a central axis 33 which runs perpendicularly thereon and halves the side edge 31 of the enveloping cube 30 and which extend in the direction of the central axes 33.
- These recesses 34 have an approximately rhombic or oval cross-sectional shape, a length 35 being a multiple of a width 36 and a depth smaller than the thickness 18 of the module 7. In the direction of the depth 37, side flanks 38 of the recesses 34 run tapered towards each other.
- the module 7 has in the region of the circumferential longitudinal and transverse side edges 39 formed between the inner surface 24 and the end surfaces 13 with the recesses 34, flush recesses 40 which correspond to the recesses 34 in terms of width 36, depth 37 and shape , but with respect to the length 35 of the recess 34 correspond to a shape halved by the delimiter 29.
- the recesses 34 and edge recesses 40 in the inner surface 24 further increase the inner surface 24 facing the combustion chamber 4 by an order of magnitude of up to 50%.
- this enlargement brings about a rapid and uniform heating of the component 7 and thus the heating device 1 due to the grid-like arrangement and thus a high overall efficiency due to the rapid radiation of heat to the surrounding air space.
- the depth 37 is less than half the thickness 18, minus half the width 27 of the groove 14.
- the module 7 has bores 41 arranged on its outer surface 15 with central axes running perpendicular to it. These bores 41 are provided in a grid dimension in the rear, edge distances 42 corresponding to half the thickness and a distance 43 between the central axes of adjacent bores 41 having the same thickness 18. A depth 44 of these bores 41 is smaller than the thickness 18.
- the block 7 is made by a dry pressing process from finely ground fireclay material, whereby a high dimensional accuracy is achieved, which brings considerable advantages in the assembly of such blocks 7 with the perfect agreement of all dimensions.
- a dry pressing process from finely ground fireclay material, whereby a high dimensional accuracy is achieved, which brings considerable advantages in the assembly of such blocks 7 with the perfect agreement of all dimensions.
- the grooves 14 arranged in the end faces 13 can be manufactured in a subsequent milling or cutting process. With appropriate tool training, the formation of the grooves 14 in the course of the pressing process is also conceivable.
- a composite of the building blocks 7 for forming the combustion chamber 4 of a heating device 1 is shown.
- the dimensional design of the building blocks 7, in which the length 20 and the height 19 are an integral multiple of the thickness 18, enables a bond in which overlapping areas 45 can be varied such that butt joints 46 for Production of a secure connection of the building blocks 7 are arranged offset from one another.
- the possibility of staggering the blocks 7 in the corner area in relation to one another is of particular importance for the production of a secure bond.
- rows of the blocks 7 placed one on top of the other are offset in the corner area, the grooves 14 being alternately aligned with the recesses 34 provided on the inner surface 24. This enables the use of specially designed connecting elements which on the one hand engage in the groove 14 and on the other hand in the recesses 34 opposite the groove 14 and secure anchoring of each row for itself and of the rows placed one on top of the other is achieved.
- connecting devices 47 show differently designed connecting devices 47.
- these consist of strip-shaped springs 48 inserted into the grooves 14, which position and stabilize the building blocks 7 on their abutting end faces 13.

- Such connecting elements 49 can thus cover the butt joints 46 and can be inserted into the recesses 34 for a firm cohesion of the building blocks 7.
- the taper of the recesses 34 results in wedge-like connections when the connecting elements 49 are inserted and a pressing force is exerted on the building blocks 7, by means of which a secure cohesion is ensured.
- Another connecting element 52 which is mainly used on the outer surface 15 of the building blocks 7, is designed as a flat bracket 53 and has cylindrical extensions 54 which interact with the bores 16 arranged in the outer surface 15 of the building blocks 7, the flat brackets 53 are flat or angled and so these connecting elements 52 can be used both in the area of the butt joints 46 but also in the area of the corner formations of the assembly.
- FIG. 6 shows an embodiment in the support area of a building block 7 forming a ceiling 55 of the combustion chamber 4 on a building block 7 forming a vertically extending wall part 56.
- the block 7 forming the ceiling 55 is supported with its inner surface 24 on the end face 13 over the entire thickness 18 of the block 7.
- the flat strip 50 of the connecting element 49 is inserted into the horizontally extending groove 14.
- the projections 51 of the connecting element 49 projecting in the direction of the module 7 forming the ceiling 55 are in engagement with the recesses 34 of this module 7, the longitudinal extent of which extends in a plane parallel to the end face 13 of this module 7.
- an L-shaped angled connecting element 52 is provided which engages with the pin-shaped extensions 51 in the bores 16 arranged in the outer surface 15 of the building blocks 7.

- the further extensions 51 spaced apart from this engage in the recesses 34 of the building blocks 7.
- a cross section of the recesses 34 is rhombic or oval, with a greatest distance 57 of longitudinal side flanks 58 lying opposite one another being greater than a thickness 59 of the extension 51.
- Front side flanks 60 are designed to be conical to one another in the direction of the depth 28 of the recesses 34.
- Such a binder 64 is also introduced into the recesses 34 and edge recesses 40 before the connection element 49 is inserted and brings about a permanent hold of the connection element 49.
- the shape of the recesses 34 and edge recesses 40 allows excess binder 64 to be pressed out .
- FIG. 9 also shows the arrangement of an inclined wall part 65, which may be required for the formation of chimneys, ceilings, etc.
- the positioning of the building blocks 7 provided with the circumferential grooves 14 is carried out by bolts 66 engaging in the grooves 14, which are inserted into the bores 16 of the building blocks 7 and protrude above the surface.
