Description

Die Erfindung betrifft ein Hängedeckensystem für die Innenauskleidung von Öfen nach dem Oberbegriff des Anspruchs 1. Mit derartigen Hängedeckensystemen werden abgehängte, hitzefeste Innendecken von Öfen gebildet, indem an parallel verlaufenden Deckenträger der Öfen Halteelemente angebracht werden und über diese Reihen von Tragsteinen befestigt sind. Zwischen den Tragsteinreihen wiederum sind Reihen vom Deckenplatten aufgenommen, die eine im wesentlichen in sich geschlossene Ofendecke bilden. In einigen Deckenplatten sind jedoch Öffnungen vorgesehen, in die von oben Brennerrohre münden, durch die der Ofen beheizt wird. Um fertigungstechnisch Spannungsrisse und damit Ausschuss zu vermindern, sind die Brennersteine geteilt ausgebildet, wobei sich die Teilungsfuge durch die Brennerrohröffnung erstreckt.The invention relates to a suspended ceiling system for the inner lining of furnaces according to the preamble of claim 1. With such suspended ceiling systems suspended, heat-resistant interior ceilings of ovens are formed by holding elements are attached to parallel ceiling support of the furnaces and fixed on these rows of support bricks. In turn, rows of ceiling tiles, which form a substantially self-contained furnace roof, are received between the rows of support rows. In some ceiling panels, however, openings are provided, open into the top of burner tubes through which the furnace is heated. In order to reduce manufacturing stress cracks and thus rejects, the burner blocks are formed divided, wherein the dividing joint extends through the burner tube opening.

Bei herkömmlichen Hängedeckensystemen, wie in DE 202 05 541 U1 beschrieben, verlaufen die Teilungsfugen der Brennersteine in Längsrichtung der Deckenplatten, d.h. quer zu den Deckenträgern des Ofens. Dadurch können die Brennersteine in ihrer Teilungsfuge ebenso ausgebildet sein wie der Übergang zwischen zwei Zwischensteinen oder zwischen einem Zwischenstein und der glatten Seite eines Brennersteins (ohne Öffnung). Die Brennersteine werden dabei aus zwei Halbsteinen gebildet, für die jeweils eine eigene Form erforderlich ist. Da der Abstand zwischen den Deckenträgern bei verschiedenen Öfen variieren kann, muss so auch die Länge der Deckenplatten unterschiedlich ausgebildet werden. Während unterschiedlich lange Zwischensteine über Variierung des Pressweges mit derselben Form hergestellt werden können, müssen bei unterschiedlich langen Brennersteinen jedoch stets neue Formen erstellt werden, was außerordentlich kostspielig ist.In conventional suspended ceiling systems, as in DE 202 05 541 U1 described, the dividing joints of the burner blocks run in the longitudinal direction of the ceiling panels, ie transverse to the ceiling beams of the furnace. As a result, the burner blocks can be designed in their dividing joint as well as the transition between two intermediate blocks or between an intermediate stone and the smooth side of a burner block (without opening). The burner stones are formed from two half stones, for each of which a separate shape is required. Since the distance between the ceiling beams may vary in different furnaces, so must the length of the ceiling panels are formed differently. While different lengths of intermediate stones can be made by varying the Pressweges with the same shape, must be at different long burner bricks but always created new forms, which is extremely expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Hängedeckensystem zu schaffen, das fertigungstechnisch vereinfacht und daher trotz hoher Flexibilität dennoch kostengünstig herstellbar ist.The invention is therefore an object of the invention to provide a suspended ceiling system that simplifies manufacturing technology and therefore despite high flexibility is still inexpensive to produce.

Diese Aufgabe wird durch ein Hängedeckensystem mit den Merkmalen des Anspruchs 1 gelöst. Indem die Teilungsfuge der Brennersteine quer zur Plattenlängsrichtung, d.h. parallel zu den Deckenträgern des Ofens gelegt wird, können die Brennersteine von der Brennerrohröffnung aus in verschiedenen Längen gepresst werden, ohne dass es dazu einer neuen Form bedarf. Die Länge der Brennersteine wird dabei ausschließlich durch den Verfahrweg beim Pressen beeinflusst. So können Decken für Öfen mit unterschiedlichen Trägerabständen bei minimierten Werkzeugkosten erstellt werden.This object is achieved by a suspended ceiling system with the features of claim 1. By dividing the kerbstones transverse to the longitudinal direction of the plate, i. placed parallel to the ceiling beams of the furnace, the burner bricks can be pressed from the burner tube opening in different lengths, without the need for a new shape. The length of the burner stones is influenced exclusively by the travel when pressing. For example, blankets for ovens with different carrier spacings can be created with minimized tool costs.

Bevorzugt ist die Teilungsfuge dabei so auszubilden, dass sie senkrecht zur Plattenebene verspringt, insbesondere z-förmig. Dadurch wird zwischen beiden Teilen des Brennersteins eine gegenseitige Auflage geschaffen und es entsteht eine Abdichtung gegen Ofengase. besonders bevorzugt ist die Teilungsfuge der Brennersteine beidseits der Brennerrohröffnung rotationssymmetrisch um die Brennerrohrlängsachse ausgebildet. Dadurch können die halben Brennersteine gegeneinander um 180° verdreht eingesetzt werden. Wenn auch noch die Seiten der beiden Brennersteinhälften identisch ausgebildet sind, ist es möglich, die Brennersteine aus zwei völlig identischen Brennerhalbsteinen zu fertigen, so dass für die Brennersteine nur eine einzige Form benötigt wird. Haben die Brennersteine in der Teilungsfuge Überlappungsvorsprünge, die an beiden Seiten der Brennerrohröffnung asymmetrisch ausgebildet sind, so ergibt sich eine besonders hohe Stabilität der Brennersteine und eine gute Abdichtung gegen Ofengase.Preferably, the dividing joint is in this case designed such that it swings perpendicular to the plane of the plate, in particular z-shaped. As a result, a mutual support is created between the two parts of the burner block and there is a seal against furnace gases. Particularly preferably, the dividing joint of the burner blocks is formed on both sides of the burner tube opening rotationally symmetrical about the burner tube longitudinal axis. As a result, half of the burner stones can be rotated against each other by 180 °. Even if the sides of the two burner brick halves are identical, it is possible to manufacture the burner bricks from two completely identical burner bristles, so that only one single mold is required for the burner bricks. The burner stones in the dividing joint have overlapping projections which are asymmetrical on both sides of the burner tube opening are formed, this results in a particularly high stability of the burner stones and a good seal against furnace gases.

Da die keramischen Materialien des Hängedeckensystems extrem hitzebeständig sein müssen, handelt es sich um sehr teures Material, so dass jede Materialersparnis wünschenswert ist. Im Gegensatz zu herkömmlichen Deckensystemen wird daher bei der erfindungsgemäßen Hängedecke vorzugsweise auf eine Feder-Nut-Verzahnung zwischen den Tragsteinen und den Deckenplatten und meist auch den Deckenplatten sowie den Brennersteinen untereinander verzichtet, da für eine derartige Feder-Nut-Verzahnung eine recht große Materialstärke erforderlich ist. Das erfindungsgemäße System bevorzugt eine Verbindung über flanschartig vorspringende Auflagebereiche und korrespondierende Vorsprünge der jeweils benachbarten Elemente, die dann auf diesen Auflagebereichen aufliegen. Dadurch können die Deckenplatten sehr viel dünner als bei herkömmlichen Deckensystemen ausgeführt werden, wodurch sich das Gewicht und die Kosten des gesamten Deckensystemen erheblich verringern. Die nicht als Brennersteine ausgebildeten Deckenplatten, d.h. die Zwischensteine sind dabei bevorzugt sogar so dünn, dass sie das Gewicht der Brennerrohre nicht mehr zu tragen in der Lage wären. Die Brennersteine können dann in angemessener Tragfähigkeit dicker als die Zwischensteine gefertigt werden, ohne dass eine Veränderung der Auflagen des gegenseitigen Verteilungssystems nötig ist. Dabei bauen die Brennersteine lediglich nach oben in den Zwischendeckenbereich höher auf, während die dem Offeninneren zugewandte Seite des Hängedeckensystems absolut plan ist.Since the ceramic materials of the suspended ceiling system must be extremely heat-resistant, it is very expensive material, so that any material savings is desirable. In contrast to conventional ceiling systems is therefore preferably omitted in the suspended ceiling according to the invention on a tongue and groove toothing between the support bricks and the ceiling panels and usually the ceiling panels and the burner bricks, as required for such a tongue and groove toothing a fairly large material thickness is. The system according to the invention prefers a connection via flange-shaped support areas and corresponding projections of the respectively adjacent elements, which then rest on these support areas. As a result, the ceiling panels can be made much thinner than in conventional ceiling systems, which significantly reduce the weight and cost of the entire ceiling systems. The non-burner ceiling tiles, i. the intermediate stones are preferably even so thin that they would not be able to carry the weight of the burner tubes in the situation. The burner bricks can then be made thicker than the intermediate blocks, with adequate load bearing capacity, without the need to alter the supports of the mutual distribution system. In this case, the burner blocks build up only higher up in the false ceiling area, while the open interior facing side of the suspended ceiling system is absolutely flat.

Der in Fig. 1 abgebildete Deckenteil zeigt zwei Reihen von Tragsteinen 1, zwischen denen Deckenplatten in Form von Brennersteinen 2 und Zwischensteinen 3 aufliegen. Die Tragsteine 1 sind über nicht dargestellte Halteelemente an ebenfalls nicht sichtbaren Deckenträgern, die jeweils parallel zur Linie D verlaufen, abgehängt. Die Brennersteine 2 weisen eine Brennerrohröffnung 4 auf und haben eine eingeformte Auflage 6 für die Brennerrohre 5, die sich darauf abstützen. Die Brennersteine 2 bestehen aus zwei Brennerhalbsteinen und haben zwischen sich eine Teilungsfuge, die parallel zu den Deckenträgern des Ofens und damit ebenfalls parallel zur Linie D verläuft.The in Fig. 1 Pictured ceiling part shows two rows of support bricks 1, between which cover plates in the form of burner bricks 2 and paving stones 3 rest. The support bricks 1 are not shown holding elements on also not visible ceiling beams, each extending parallel to the line D, suspended. The burner blocks 2 have a burner tube opening 4 and have a molded support 6 for the burner tubes 5, which are supported thereon. The burner stones 2 consist of two burner halves and have between them a dividing joint, which runs parallel to the ceiling beams of the furnace and thus also parallel to the line D.

Im einzelnen sind die Brennersteine in den Fig. 2 und 3 dargestellt. Fig. 2 zeigt einen Brennerstein 2, dessen beide Brennerhalbsteine zur Verdeutlichung leicht auseinander gezogen dargestellt sind. An der Oberseite rings der Brennerrohröffnung 4 hat der Brennerstein 2 eine Vertiefung 6 zur Aufnahme des Brennerrohrs 5. Wie dargestellt verspringt die Teilungsfuge des Brennersteins 2 senkrecht zur Plattenebene E und zwar bei der dargestellten Ausführungsform z-förmig. Dabei hat die eine Seite des Brennerhalbsteins untenseitig einen Vorsprung 7, der als Auflage für einen oberseitigen Vorsprung 8 des gegenüberliegenden Brennerhalbsteins dient. Auf der anderen, in der Zeichnung hinteren Seite des Brennersteins 2 sind oberer und unterer Vorsprung jeweils an dem anderen Brennerhalbstein ausgebildet, so dass die Teilungsfuge beidseits der Brennerrohröffnung 4 rotationssymmetrisch um die Brennerrohrlängsachse B ausgebildet ist. In der Teilungsfuge selbst sind die Überlappungsvorsprünge 7, 8 bezüglich der Brennerrohröffnung 4 asymmetrisch, wodurch der Brennerstein 3 in sich eine gute Stabilität erhält und durch die asymmetrische Verzahnung auch eine gute Deckenabdichtung gegen Ofengase bildet.In detail, the burner stones in the Fig. 2 and 3 shown. Fig. 2 shows a burner block 2, the two burner half stones are shown slightly pulled apart for clarity. At the top of the burner tube opening 4 around the burner block 2 has a recess 6 for receiving the burner tube 5. As shown, the dividing joint of the burner block 2 jumps perpendicular to the plate plane E and indeed z-shaped in the illustrated embodiment. In this case, the one side of the burner half-face at the bottom has a projection 7, which serves as a support for an upper-side projection 8 of the opposite burner half-brick. On the other, in the drawing rear side of the burner block 2 upper and lower projection are each formed on the other burner half stone, so that the dividing joint is formed on both sides of the burner tube opening 4 rotationally symmetrical about the burner tube longitudinal axis B. In the dividing joint itself, the overlapping projections 7, 8 with respect to the burner tube opening 4 are asymmetrical, whereby the burner block 3 in itself receives a good stability and forms by the asymmetric toothing and a good ceiling seal against furnace gases.

An seinen Außenseiten hat der Brennerstein 2 einen umlaufenden Vorsprung 9, mit dem er wie in Fig. 1 erkennbar auf entsprechenden Auflagebereichen der Tragsteine 1 und der Zwischensteine 3 aufliegt.On its outer sides, the burner brick 2 has a circumferential projection 9, with which he as in Fig. 1 recognizable rests on corresponding support areas of the supporting stones 1 and the intermediate stones 3.

Insbesondere Fig. 3 zeigt, dass die Brennerhalbsteine bei dieser bevorzugten Ausführungsform absolut identisch sind, so dass nur eine Pressform benötigt wird.Especially Fig. 3 shows that the burner cermets are absolutely identical in this preferred embodiment, so that only one mold is needed.

Fig. 4 veranschaulicht einen bei dem erfindungsgemäßen Hängedeckensystem bevorzugten Tragstein. Dieser hat an dem oberen Ende oder Kopf Vorsprünge 11, die in Halteelemente zur Befestigung an den Deckenträgern eingehängt werden können. Bevorzugt befinden sich die Vorsprünge 11 an den parallel zu den Deckenträgern verlaufenden Längsseiten L der Tragsteine 1, da dies eine einfache Ausbildung der Halteelemente zur Festlegung an den meist als Doppel-T-Trägern ausgebildeten Deckenträgern begünstigt. In Längsrichtung I haben die Tragsteine in ihrem unteren Bereich einerseits einen Vorsprung 12 und andererseits einen Auflagebereich 13, wodurch die Tragsteine 1 bei eingebauter Hängedecke (siehe Fig. 1) unmittelbar aneinander anschließen und sich mit Vorsprung 12 und Auflagebereich 13 überlappend gegen Ofengase abdichten. Am unteren Ende ihrer Längsseiten L haben die Tragsteine beiderseits flanschartig vorspringende Auflagebereiche 14, die zur Aufnahme der Brennersteine 2 und Zwischensteine 3 dienen (siehe Fig. 1). Fig. 4 illustrates a preferred in the inventive suspended ceiling system support stone. This has at the upper end or head projections 11 which can be suspended in holding elements for attachment to the ceiling beams. Preferably, the projections 11 are located on the parallel to the ceiling beams extending longitudinal sides L of the supporting stones 1, since this favors a simple design of the holding elements for attachment to the usually designed as a double-T-beams ceiling beams. In the longitudinal direction I, the support stones have in their lower region, on the one hand, a projection 12 and, on the other hand, a support region 13, as a result of which the support stones 1 with built-in suspended ceiling (see Fig. 1 ) connect directly to each other and seal with projection 12 and support area 13 overlapping against furnace gases. At the lower end of their longitudinal sides L, the support stones on both sides have flange-shaped projecting support regions 14 which serve to receive the burner stones 2 and intermediate stones 3 (see FIG Fig. 1 ).

Fig. 5 zeigt einen Zwischenstein, wie er jeweils zwischen zwei Brennersteinen der Fig. 2 und 3 eingesetzt werden kann. Sämtliche Zwischensteine des gezeigten Systems haben an ihren gegenüberliegenden Querseiten Q Vorsprünge 15, mit denen sie auf den Auflagebereichen 14 der Tragsteine 1 aufliegen. An den Längsseiten hat der in Fig. 5 dargestellte Zwischenstein 3 selbst Auflagebereiche 16 für die Vorsprünge 9 der Brennersteine 2 oder 17 eines benachbarten Zwischensteins 3'. Der in Fig. 5 dargestellte Zwischenstein wird als H-Stein bezeichnet. Fig. 5 shows an intermediate stone, as he between each two burner stones of the Fig. 2 and 3 can be used. All intermediate blocks of the system shown have at their opposite transverse sides Q projections 15, with which they rest on the support areas 14 of the support bricks 1. On the long sides has the in Fig. 5 illustrated intermediate stone 3 itself support areas 16 for the projections 9 of the burner stones 2 or 17 of an adjacent intermediate block 3 '. The in Fig. 5 shown intermediate stone is called H-stone.

Fig. 6 hingegen zeigt einen als Z-Stein bezeichneten Zwischenstein 3', der an einer Längsseite ebenfalls einen Vorsprung 17 aufweist, während die gegenüberliegende Längsseite dieses Zwischensteins 3' den Auflagebereich 16 ausbildet. Diese Z-Steine eignen sich, um unmittelbar benachbart in eine Reihe eingesetzt zu werden, wobei jeweils der Vorsprung 17 auf dem Auflagebereich 16 des benachbarten Steines aufliegt. Fig. 6 on the other hand, there is an intermediate stone 3 'called a Z-stone, which likewise has a projection 17 on one longitudinal side, while the opposite longitudinal side of this intermediate block 3' forms the support region 16. These Z-stones are suitable to be used immediately adjacent to a row, wherein each of the projection 17 rests on the support area 16 of the adjacent stone.

Fig. 7 zeigt verschiedene Steinreihen, wie sie in einem Ofen innerhalb eines Hängedeckensystems vorkommen können. Fig. 7a zeigt eine Reihe von Tragsteinen 1, während in Fig. 7b eine Reihe von Z-Zwischensteinen 3' zu sehen ist. In Fig. 7c ist in dem mittleren Zwischenstein 3' eine Öffnung für ein Be- oder Entlüftungsrohr 20 dargestellt. Da derartige Be- und Entlüftungsrohre 20 weniger schwer als Brennerrohre 5 sind, muss dazu der entsprechende Zwischenstein 3' nicht dicker ausgebildet sein, sondern kann lediglich mit einem Loch versehen werden. Fig. 7d und 7e zeigen Reihen, mit jeweils zwischen Zwischensteinen 3, 3' eingesetzten Brennersteinen 2. Dabei ist deutlich erkennbar, dass die Brennersteine 2 dicker ausgebildet sind, um die Brennerrohre 5 aufnehmen zu können. Fig. 7f zeigt eine Draufsicht auf eine Steinreihe entsprechend e und f mit jeweils seitlichen Reihen von Tragsteinen 1. Fig. 7 shows different rows of stones, as they can occur in an oven within a suspended ceiling system. Fig. 7a shows a series of support stones 1, while in Fig. 7b a series of Z-piers 3 'can be seen. In Fig. 7c is in the middle intermediate stone 3 'an opening for a ventilation pipe 20 shown. Since such ventilation pipes 20 are less difficult than burner tubes 5, the corresponding intermediate stone 3 'does not have to be made thicker, but can only be provided with a hole. Fig. 7d and 7e show rows, each with intermediate blocks 3, 3 'used burner bricks 2. It is clearly seen that the burner blocks 2 are formed thicker to accommodate the burner tubes 5 can. Fig. 7f shows a plan view of a row of stones according to e and f, each with lateral rows of support stones. 1

Das erfindungsgemäße Hängedeckensystem ist sehr wirtschaftlich und unter größerer Schonung von Materialressourcen als bei bisherigen Hängedeckensystemen herstellbar. Gleichzeitig verfügt es über hohe Stabilität und eine leichte Montierbarkeit. In seiner Abdichtung gegenüber Ofengasen steht es herkömmlichen Systemen nicht nach. Insgesamt kann das erfindungsgemäße Hängedeckensystem daher vorteilhaft zur Ofenauskleidung eingesetzt werden und eignet sich auch für die Nachrüstung und Erneuerung.The suspended ceiling system according to the invention can be produced very economically and with greater protection of material resources than in previous suspended ceiling systems. At the same time it has high stability and easy mountability. In its seal against furnace gases, it does not lag behind conventional systems. Overall, the suspended ceiling system according to the invention can therefore be used advantageously for furnace lining and is also suitable for retrofitting and renovation.
