Description

Die Erfindung betrifft ein System zum Befestigen von feuerfesten Platten an Kesselrohrwänden insbesondere von Dampferzeugern und Verbrennungsanlagen, wobei die Platten an metallenen Rohrstegen gehalten sind, die zwischen den Rohren befestigt insbesondere angeschweißt sind.The invention relates to a system for attaching refractory panels Boiler tube walls, in particular of steam generators and combustion plants, wherein the plates are held on metal tube webs between the Pipes are attached in particular welded.

Es ist bekannt, feuerfeste Rohrschutzplatten an Kesselrohrwänden dadurch zu befestigen, dass die Platten einander überdecken, so dass es äußerst schwierig war, einzelne Platten zu ersetzen. Ferner neigten bisherige Plattensysteme dazu, sich dachziegelartig aufzuschieben. Darüber hinaus ist es bekannt, an den zwischen den Rohren befestigten Stegen Halteeisen anzuschweißen, die schräg nach oben ragen, um die Platten mit rückseitigen Ausnehmungen auf diese Halteeisen hängen zu können. Der hierdurch gegebene Halt hat sich als nicht ausreichend erwiesen. Auch ist die Befestigung der Halteeisen an den Stegen arbeitsaufwendig. It is known to use fireproof tube protection plates on boiler tube walls attach that the plates overlap each other, making it extremely difficult was to replace individual plates. Previous plate systems also tended to to slide up like a roof tile. In addition, it is known to the between the tubes fastened webs to weld brackets that are at an angle protrude upward around the panels with recesses on the back of them To be able to hang holding irons. The hold given by this has not turned out to be proven sufficiently. Also the attachment of the holding iron to the webs labor intensive.

Aufgabe der Erfindung ist es, ein Befestigungssystem der eingangs genannten Art so zu verbessern, dass bei einfacher Herstellung ein sicherer Halt gegeben ist und die Platten einzeln bei geringem Aufwand austauschbar sind.The object of the invention is to provide a fastening system of the type mentioned to improve so that there is a secure hold with simple manufacture and the plates can be replaced individually with little effort.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in oder an den Rohrstegen metallene Bolzen insbesondere waagerecht befestigt sind, die nach vorne über die Rohre hinausragen und jeweils in einer rückseitigen Sackbohrung der Platte formschlüssig einliegen.This object is achieved in that in or on the Metal web studs are particularly fastened horizontally, according to protrude from the front of the pipes and each in a blind hole on the back insert the plate positively.

Durch eine solche Bolzenbefestigung ist jede Platte bei Reparaturen einzeln austauschbar, ohne dass Nachbarplatten bewegt oder beschädigt werden müssen. Die Rohre sind sicher geschützt, da die Platten an ihrer Vorderseite keine Öffnungen aufweisen und damit vorderseitig unversehrt sind. Die Vorderseite ist nicht durch Halteelemente durchbrochen, um dort nachträglich abgedichtet zu werden, so dass ein zusätzlicher Verschleiß bei großer Hitze und korrosiver Kesselatmosphäre verhindert wird. Ferner sind Herstellung und Montage der Bolzen und Platten einfach und leicht durchführbar.With such a bolt fastening, each plate is individual for repairs interchangeable, without neighboring plates being moved or damaged have to. The pipes are safely protected since the plates on their front are none Have openings and are therefore undamaged on the front. The front is not broken through by holding elements in order to be subsequently sealed there be, so that additional wear in high heat and more corrosive Boiler atmosphere is prevented. Furthermore, manufacture and assembly of the Bolts and plates simple and easy to carry out.

Eine sichere und einfache Befestigung wird dadurch geschaffen, dass das in der Sackbohrung einliegende vordere Ende des Bolzens in zwei oder mehr federnde Finger aufgeteilt ist, die in einer inneren Erweiterung der Sackbohrung eingerastet liegen.A secure and simple attachment is created by the fact that in the Blind bore inserting the front end of the bolt into two or more resilient Finger is split, which snapped into an internal extension of the blind hole lie.

Ein besonders sicherer Halt ist gegeben, wenn zumindest das in der Sackbohrung einliegende vordere Ende des Bolzens einen nach vorne zur Platte hin sich öffnenden inneren Hohlraum insbesondere zwischen den Fingern aufweist, der durch Mörtel oder Kitt ausfüllbar ist. Besonders vorteilhaft ist es hierbei, wenn die Außenseite des vorderen Endes des Bolzens im Bereich der Finger im Durchmesser sich nach vorne hin insbesondere konisch verjüngt.A particularly secure hold is given if at least that in the blind hole Insert the front end of the bolt forward towards the plate opening inner cavity, in particular between the fingers, the can be filled with mortar or putty. It is particularly advantageous here if the Outside of the front end of the bolt in the area of the fingers in the Diameter tapers in particular towards the front.

Eine einfache Befestigung der Bolzen an den Stegen wird erreicht, wenn das rückseitige Ende des Bolzens in einer Bohrung des Rohrsteges befestigt insbesondere geschweißt einliegt. Besonders wirtschaftlich ist es, wenn die Bolzen in den Steg eingeschossen werden. Hierdurch wird eine besonders schnelle Montage erreicht.A simple attachment of the bolts to the webs is achieved if that the rear end of the bolt is fastened in a hole in the tube web especially welded. It is particularly economical if the Bolts are shot into the bridge. This makes one special quick assembly achieved.

Eine Kesselrohrwand weist zahlreiche senkrechte Rohre 1 auf, die in gleichen Abständen nebeneinander angeordnet sind, wobei die Rohre durch Rohrstege 2 miteinander verbunden sind. Die metallenen Rohrstäbe 2 sind an den Rohren 1 angeformt oder angeschweißt und liegen in einer Ebene, die auch durch die Rohrachsen verläuft.A boiler tube wall has numerous vertical tubes 1 which are the same Distances are arranged side by side, the tubes being separated by tube webs 2 are interconnected. The metal tube rods 2 are on the tubes 1 molded or welded and lie in a plane that is also by the Pipe axes runs.

Mittig zwischen zwei Rohren 1 sind in an den Stegen 2 metallene Bolzen 3 befestigt. Hierzu werden die Bolzen 3 entweder auf die Rohrstege 2 mit ihren rückseitigen Enden 4 aufgeschweißt oder in nicht dargestellten Bohrungen in den Stegen 2 befestigt. Hierbei liegen die Bolzen 3 mittig zwischen zwei Rohren 1. Alternativ können aber auch die metallenen Bolzen 3 mit ihren rückseitigen Enden 4 in die Stege 2 eingeschossen werden. In the middle between two tubes 1 there are metal bolts 3 on the webs 2 attached. For this purpose, the bolts 3 are either on the webs 2 with their back ends 4 welded or in holes, not shown, in the Bridges 2 attached. Here, the bolts 3 are located centrally between two tubes 1. Alternatively, however, the metal bolts 3 with their rear ends can also be used 4 are shot into the webs 2.

Die Bolzen 3 ragen über die Vorderseite der Rohre 1 hinaus und liegen mit ihrem vorderen Ende 5 in waagerechten Sackbohrungen 6 ein, die sich zur Rückseite einer feuerfesten Keramikplatte 7 öffnen. Hierbei wird unter einer "Sackbohrung" eine achssymmetrische Öffnung verstanden, die nicht durch ein Bohren, sondern während des Formens der Platte aus keramischem Material hergestellt wird.The bolts 3 protrude beyond the front of the tubes 1 and lie with their front end 5 in horizontal blind holes 6, which are to the rear open a fireproof ceramic plate 7. Here is under a "blind hole" understood an axisymmetric opening, not by drilling, but is made of ceramic material during the molding of the plate.

Die Sackbohrung 6 besitzt an ihrem inneren Ende eine innere Erweiterung 8, so dass ihr Durchmesser am inneren Ende größer ist als im übrigen Bereich.The blind bore 6 has an inner extension 8 at its inner end, see above that its diameter is larger at the inner end than in the rest of the area.

Das vordere Ende 5 des Bolzens 3 ist außen entsprechend der inneren Erweiterung 8 geformt. Hierbei verjüngt sich das vordere Ende 5, wobei diese konische Verjüngung 9 beim Eindringen in die Bohrung 6 am äußeren Bohrungsrand auf eine konische Fläche 10 trifft, durch die das untere Ende 5 zusammendrückbar ist. Hierzu ist das vordere Ende 5 des Bolzens 3 in einzelne Finger 11 aufgeteilt, die sich achsparallel zur Bolzenachse 12 erstrecken. Zur Schaffung dieser Finger 11 besitzt das vordere Ende 5 einen koaxialen inneren Hohlraum in Form einer Sackbohrung, die sich zum vorderen Ende 5 hin öffnet. Die hierdurch entstandene zylindrische Außenwand des Bolzens 3 ist durch mehrere Längseinschnitte 14 in die Finger 11 aufgeteilt. In Fig. 7 sind acht Finger 11 dargestellt. Diese Anzahl kann aber auch größer oder kleiner sein.The front end 5 of the bolt 3 is the outside corresponding to the inner Extension 8 shaped. Here, the front end 5 tapers, this conical taper 9 when entering the bore 6 on the outside Border edge meets a conical surface 10 through which the lower end 5 is compressible. For this purpose, the front end 5 of the bolt 3 is in individual Split fingers 11, which extend axially parallel to the pin axis 12. to Creation of these fingers 11, the front end 5 has a coaxial inner Cavity in the form of a blind hole that opens towards the front end 5. The resulting cylindrical outer wall of the bolt 3 is through divided several longitudinal incisions 14 in the fingers 11. In Fig. 7 there are eight fingers 11 shown. However, this number can also be larger or smaller.

Ehe die Platten 7 auf die Rohrwand aufgesetzt werden, wird jede Platte rückseitig mit Mörtel bedeckt. Dieser Mörtel dringt auch in die Sackbohrung 6 ein, so dass beim Aufsetzen der Platte auf den Bolzen 3 der Mörtel in dem inneren Hohlraum 13 des Bolzens dringt und damit nach dem Einschnappen des vorderen Endes 5 in die Erweiterung 8 der Mörtel aushärtet und damit verhindert, dass die Finger 11 sich wieder nach innen bewegen können. Somit ist ein besonders sicherer Halt der Platten 7 an den Bolzen 3 und damit an der Rohrwand gegeben. Die Bolzen sind damit Dübel, die in die Sacköffnung 6 der Platte eindringen, einrasten und durch die innere erhärtete Mörtelfüllung gegen ein Herausziehen gesichert sind.Before the plates 7 are placed on the pipe wall, each plate is on the back covered with mortar. This mortar also penetrates into the blind hole 6, so that when placing the plate on the bolt 3 of the mortar in the inner cavity 13 of the bolt penetrates and thus after the front end 5 has snapped in in the extension 8 of the mortar hardens and thus prevents the fingers 11 can move back inside. This is a particularly secure hold the plates 7 on the bolt 3 and thus given on the pipe wall. Bolts are thus dowels that penetrate into the pocket opening 6 of the plate, snap in and are secured against pulling out by the inner hardened mortar filling.
