Die Erfindung betrifft eine Rohrschutzplatte aus einem feuerbeständigen Material gemäss dem Oberbegriff des Anspruches 1 sowie eine Wandauskleidung für einen Müllverbrennungsofen.The invention relates to a pipe protection plate made of a fire-resistant material according to the preamble of claim 1 and a wall lining for a refuse incinerator.

Rohrschutzplatten zum Schutz von mindestens zwei entlang einer Ofenwand vertikal verlaufenden und miteinander über einen Steg verbundenen Kühlrohren sind bekannt. Sie sind mit mindestens einer vertikal verlaufenden, durchgehenden Nut versehen und werden mit dieser eingehängt, derart, dass zwischen der Rohrschutzplatte einerseits und den Kühlrohren sowie den Stegen anderseits ein mit Mörtel füllbarer Raum gebildet ist. In der Regel ist eine Platte zum Schutz von zwei bzw. drei Kühlröhren vorgesehen und weist dementsprechend zwei vertikale Nuten auf, mit denen sie auf zwei je einem Steg zugeordnete Nutensteine aufgesetzt wird. Auch die Nuten mit den darin befindlichen Nutensteinen werden mit dem Beton gefüllt. Eine Wandauskleidung besteht dann aus mehreren aufeinandergesetzten und/oder nebeneinander angeordneten Rohrschutzplatten.Pipe protection plates for protecting at least two along a furnace wall vertically extending and connected to each other via a web cooling tubes are known. They are provided with at least one vertically extending, continuous groove and are hooked with this, such that between the pipe protection plate on the one hand and the Cooling tubes and the webs on the other hand, a fillable with mortar space is formed. In general, a plate for protecting two or three cooling tubes is provided and accordingly has two vertical grooves, with which it is placed on two each associated with a web slot nuts. The grooves with the sliding blocks therein are filled with the concrete. A wall lining then consists of several juxtaposed and / or juxtaposed pipe protection plates.

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.

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 support (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.

Diese Mutter 11 mit Aussenkonus ist auf einem vom Steg 2 wegragenden Distanzbolzen 12 angeordnet. Sie ist demgemäss kegelstumpfförmig ausgebildet und auf einem Gewindeteil 12a des Gewindebolzens 12 um 90° zum Steg 2 verstellbar, wobei sie einen sich in Richtung zum Steg 2 hin verjüngenden Umfang 11a aufweist.Each pipe protection plate 3 is provided for the protection of at least two, possibly of three boiler tubes 1. The pipe protection plate 3 is positioned relative to the boiler tubes 1 and the webs 2, that between a concrete-filled space 4 is formed. The means for positioning the respective pipe protection plate 3 are shown in detail in Fig. 4. The pipe protection plate 3 is provided with at least one vertically extending, continuous groove as a cone groove 10 (in the illustrated embodiment, the pipe protection plate 3 has two grooves 10, see Fig. 1), with which they held on a corresponding web 2 mother 11 with outer cone can be placed. This nut 11 with outer cone is disposed on a projecting from the web 2 spacer pin 12. 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 toward 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, for example, 25 mm (compare b 1 according to FIG. 2), then it increases over the length of approximately 250 mm to the width b 2 of 30 mm (ie approximately 1 mm per side more on the length of 100 mm).
