Die US 2006/0101740 A1 offenbart eine Rohrschutzplatte zum Schutz von drei Kühlröhren und weist zwei gerade verlaufende, vertikale Nuten auf, mit denen sie von oben auf zwei auf dem jeweiligen Steg gehaltene Nutensteine aufgesetzt wird, bis die Nuten mit ihrem oberen, stirnseitigen Ende an den Nutensteinen anschlagen und somit die Rohrschutzplatte auf den Nutensteinen aufgehängt wird. Dabei wird zwischen der Rohrschutzplatte einerseits und den Kühlrohren sowie den Stegen anderseits ein mit Mörtel oder Beton füllbarer Raum gebildet. Auch die Nuten mit den darin befindlichen Nutensteinen werden mit dem Mörtel oder Beton gefüllt.The US 2006/0101740 A1 discloses a pipe protection plate for the protection of three cooling tubes and has two straight, vertical grooves, with which it is placed from above on two held on the respective web nuts until the grooves abut with their upper, front end on the sliding blocks and thus the Pipe protection plate is hung on the sliding blocks. In this case, between the pipe protection plate on the one hand and the cooling tubes and the webs on the other hand, a fillable with mortar or concrete space is formed. The grooves with the sliding blocks therein are filled with mortar or concrete.

In gleicher Art und Weise wird auch die Rohrschutzplatte nach der WO 2005/064255 A , die für zwei mit einem Steg verbundene Kühlrohre vorgesehen ist, mit dem oberen, stirnseitigen Ende ihrer Nut auf einen Nutenstein aufgehängt.In the same way, the pipe protection plate after the WO 2005/064255 A , which is provided for two connected with a web cooling tubes, suspended with the upper, frontal end of its groove on a sliding block.

Für zwei mit einem Steg verbundene Kühlrohre ist auch die Rohrschutzplatte nach der DE 20 2005 018131 U1 vorgesehen. Auch sie ist mit einer vor dem oberen Rand endenden Nut versehen und wird von oben auf einen Nutenstein aufgeschoben. Bei dieser Rohrschutzplatte weist die Nut eine untere Ausnehmung bzw. Erweiterung auf, die waagerechte Anlageflächen bildet. Das Mörtel- bzw. Betonmaterial bildet in der Ausnehmung nach dem Erhärten einen Sockel, auf dem die Rohrschutzplatte unveränderlich in ihrer Höhe ruht.For two with a web connected cooling pipes and the pipe protection plate is after the DE 20 2005 018131 U1 intended. Also, it is provided with a groove ending in front of the upper edge and is pushed from above onto a sliding block. In this pipe protection plate, the groove has a lower recess or extension, which forms horizontal contact surfaces. The mortar or concrete material forms in the recess after hardening a pedestal on which the pipe protection plate invariably rests in their height.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Rohrschutzplatte der eingangs genannten Art sowie die mehrere Rohrschutzplatten umfassende Wandauskleidung weiter zu verbessern.The present invention has for its object to further improve the pipe protection plate of the type mentioned above and the wall lining comprising a plurality of pipe protection panels.

Diese Aufgabe wird erfindungsgemäss durch eine Rohrschutzplatte mit den Merkmalen des Anspruches 1 sowie durch eine Wandauskleidung nach Anspruch 8 und durch eine Ofenwand nach Ansprüchen 4 und 9 gelöst.This object is achieved according to the invention by a pipe protection plate having the features of claim 1 and by a wall lining according to claim 8 and by a furnace wall according to claims 4 and 9.

Weitere bevorzugte Ausgestaltungen der erfindungsgemässen Rohrschutzplatte bilden den Gegenstand der abhängigen Ansprüche.Further preferred embodiments of the inventive pipe protection plate form the subject of the dependent claims.

Die erfindungsgemässen Rohrschutzplatten werden mit ihren Konusnuten von oben auf die entsprechenden, zuvor in ihrer Distanz den Stegen gegenüber eingestellten Nutensteine aufgesetzt, bis ihre Seitenwände am Umfang der jeweiligen Mutter mit Aussenkonus zur Auflage kommen (d.h. nicht wie bisher, bis sie auf den darunterliegenden Rohrschutzplatten stehen). Danach wird der Raum zwischen den Rohrschutzplatten und den Kühlrohren sowie den Stegen mit Beton gefüllt, wobei der Beton auch in die Konusnuten mit den darin befindlichen Muttern mit Aussenkonus eingebracht (eingegossen) wird. Durch den sich erfindungsgemäss von oben nach unten vergrössenden Abstand der Nuten-Seitenwände wird erreicht, dass die auf dem erhärteten Betonmaterial "sitzenden" Rohrschutzplatten bei temperaturbedingten Dilatationen diesem gegenüber nach unten oder nach oben bewegt werden können, wobei vorteilhafterweise auch die Dilatationen benachbarter Rohrschutzplatten der Wandauskleidung über zwischen ihren Plattenrändern eingelegten Filze aufgenommen werden können.The inventive pipe protection plates are placed with their Konusnuten from the top of the corresponding previously set in their distance to the webs against sliding nuts until their side walls on the circumference of each nut with outer cone to rest (ie not as before, until they are on the underlying pipe protection plates ). Thereafter, the space between the pipe protection plates and the cooling tubes and the webs is filled with concrete, wherein the concrete is also introduced into the conical grooves with the nuts therein with external cone (poured). As a result of the distance between the groove side walls, which increases according to the invention from top to bottom, it is ensured that the pipe protection plates "seated" on the hardened concrete material cause dilatation due to temperature can be moved downwards or upwards, wherein advantageously also the dilatations of adjacent pipe protection plates of the wall lining can be taken up by inserted between their plate edges felts.

It is accordingly frusto-conical and adjustable on a threaded portion 12a of the threaded bolt 12 by 90 ° to the web 2, wherein it has a tapered towards the web 2 towards 11a periphery.

Die jeweilige Konusnut 10 weist zwei gegenüberliegende Seitenwände 13 auf, die von einer Nutenbasis 14 in Richtung zum Nuteneingang 15 hin mit einem dem Kegelstumpfwinkel der Mutter 11 entsprechenden Winkel zusammenlaufen, derart, dass sie einen in der Konusnut 10 befindlichen Mutter 11 mit Aussenkonus hintergreifen.The respective cone groove 10 has two opposite side walls 13 which converge from a groove base 14 in the direction of the groove inlet 15 with an angle corresponding to the truncated cone angle of the nut 11, such that they engage behind a nut 11 located in the cone groove 10 with external cone.

Erfindungsgemäss ist die Konusnut 10 so ausgebildet, dass sich zudem der Abstand der Seitenwände 13 von oben nach unten vergrössert. Beträgt die maximale Nutenbreite oben beispielsweise 25 mm (vgl. b1 nach Fig. 2), so steigt sie über die Länge von ca. 250 mm auf die Breite b2 von 30 mm an (d.h. ungefähr 1 mm pro Seite mehr auf der Länge von 100 mm).According to the invention, the cone groove 10 is formed so that, in addition, the distance between the side walls 13 increases from top to bottom. If the maximum groove width at the top is 25 mm, for example (compare b 1) Fig. 2 ), it increases over the length of about 250 mm to the width b 2 of 30 mm (ie about 1 mm per side more on the length of 100 mm).

Die Rohrschutzplatte 3 weist zu beiden seiten der jeweiligen Konusnut 10 vertikal verlaufende konkave Wölbungen 20 für die zu schützenden Kühlrohre 1, mit welchen die auf die Muttern 11 mit Aussenkonus aufgesetzte Rohrschutzplatte 3 jeweils einen mit Beton füllbaren Teilringraum 4a um das jeweilige Kühlrohr 1 begrenzt. Der Abstand der Wölbungen 20 von den Kühlrohren 1 ist über die auf den Gewindebolzen 12 verstellbaren Muttern 11 mit Aussenkonus einstellbar.The pipe protection plate 3 has on both sides of the respective conical groove 10 vertically extending concave curvatures 20 for the cooling pipes 1 to be protected, with which the nuts 11 with outer cone patch pipe protection plate 3 each bounded with concrete part ring space 4a bounded by the respective cooling tube 1. The distance of the bulges 20 of the cooling tubes 1 is adjustable on the threaded bolt 12 adjustable nuts 11 with outer cone.

Wie insbesondere aus Fig. 3 ersichtlich, sind sowohl am oberen als auch am unteren Plattenrand der jeweiligen Rohrschutzplatte 3 Auflageflächen 14, 15, 16 bzw. 14', 15', 16' vorhanden, die zur Aufnahme einer benachbarten oberen Rohrschutzplatte 3 bzw. zum Aufsetzen auf eine benachbarte untere Rohrschutzplatte 3 vorgesehen sind. Beim dargestellten Ausführungsbeispiel bildet eine obere, an die mit den Wölbungen 20 versehene Frontseite anschliessende schräge Auflagefläche 14 zusammen mit einer weiteren Auflagefläche 15 eine Art Vertiefung am oberen Plattenrand, während eine gegenüberliegende untere, schräge Auflagefläche 14' zusammen mit einer weiteren Auflagefläche 15' einem gegengleichen Vorsprung am unteren Plattenrand zugeordnet ist. Es ist vorgesehen, zwischen die Auflageflächen 14, 16 bzw. 14', 16' benachbarter Rohrschutzplatten 3 feuerfeste Filzeinlagen einzubringen.As in particular from Fig. 3 3, bearing surfaces 14, 15, 16 and 14 ', 15', 16 'are provided both at the upper and at the lower edge of the plate of the respective pipe protection plate, which for receiving an adjacent upper pipe protection plate 3 or for placing on an adjacent lower pipe protection plate 3 are provided.
