The shorter side surfaces are arranged to extend at an angle ( alpha ) of between 20 DEG and 50 DEG to the longitudinal axis while the longer side surfaces are arranged to extend at an angle ( beta ) of between 10 DEG and 30 DEG to the longitudinal axis. The refractory plate can thus be optimally clamped and an increased service life is thus consequently achieved.

Description

Die Erfindung betrifft eine feuerfeste Platte für einen Schiebeverschluss nach dem Oberbegriff des Anspruchs 1, sowie eine Spannvorrichtung nach dem Oberbegriff des Anspruchs 8 für diese Platte.The invention relates to a refractory plate for a sliding closure according to the preamble of claim 1, and a tensioning device according to the preamble of claim 8 for this plate.

Bei einem bekannten Schiebeverschluss gemäss der Druckschrift DE-C2 35 22 134 sind feuerfeste Platten vorgesehen, die nicht von einer Metallbandage umfasst sind. Wenigstens zwei einander gegenüberliegende Bereiche des Randes sind bei einer jeweiligen Platte gegen die Gleitfläche hin verjüngend ausgebildet. Diese sich verjüngenden Randbereiche sind dabei jeweils für einen Eingriff mit einer angepassten, abgeschrägten Fläche eines Klemmelementes bestimmt. Die Abmessungen und Winkel der Platte sind im Bereich der abgeschrägten Flächen von der Gleitfläche zur hinteren Auflagefläche derart gewählt, dass die Klemmelemente sowohl eine gegen die Mitte der Platte wie auch eine gegen die hintere Auflagefläche gerichtete Kraftkomponente ausüben. Eine jeweilige Platte kann dabei die Form eines Rechtecks mit abgerundeten Ecken oder die Form eines Sechsecks aufweisen, welches aus zwei gleichschenkligen Trapezen mit gemeinsamer Basis gebildet ist.In a known sliding closure according to the document DE-C2 35 22 134 fire-resistant plates are provided, which are not of a metal bandage are included. At least two opposite each other Areas of the border are at a respective Plate tapered towards the sliding surface. This tapered edge areas are each for an intervention with an adapted, bevelled surface of a clamping element certainly. The dimensions and angles of the plate are in the area of the bevelled surfaces from the sliding surface to rear bearing surface chosen such that the clamping elements both against the center of the plate as well as against the exert a directed force component on the rear support surface. A each plate can have the shape of a rectangle with rounded Have corners or the shape of a hexagon, which formed from two isosceles trapezoids with a common base is.

Diese bekannte Verspannungart von feuerfesten Platten in einem Schiebeverschluss ist mit verschiedenen Nachteilen verbunden. Zum einen sind für die Einspannung einer jeweiligen Platte mehrere Klemmelemente vorgesehen, die einzeln mittels Schrauben oder dergleichen gegen den entsprechenden Randbereich der Platte festgespannt werden. Dies führt zu einem unverhältnismässigen Arbeitsaufwand bei der Montage. Darüberhinaus ist bei dem ausserordentlich rauhen sowie heissen Betrieb ein einwandfreies Funktionieren der Schrauben und der Gewindelöcher auf die Dauer nicht gewährleistet. Im weiteren sind die feuerfesten Platten mit den in ihrem Randbereich vorgesehenen Verjüngungen relativ aufwendig herzustellen und die durch diese Verjüngungen hervorgerufenen spitzen Plattenkanten können insbesondere bei einem Schlag leicht ausbrechen.This well-known type of bracing of refractory panels in one Sliding lock has various disadvantages. On the one hand, there are several for clamping a particular plate Clamping elements provided individually by means of screws or the like against the corresponding edge area of the plate be tightened. This leads to a disproportionate Assembly workload. In addition, the is extraordinary rough and hot operation a perfect Function of the screws and the threaded holes in the long run not guaranteed. Furthermore, the refractory panels are included relative to the tapering provided in its edge area elaborate to manufacture and those caused by these rejuvenations pointed plate edges can be especially in a Break out the blow slightly.

Aufgabe der vorliegenden Erfindung besteht demgegenüber darin, eine feuerfeste Platte nach der eingangs beschriebenen Gattung zu schaffen, die bei günstiger Herstellung eine solche äussere Form aufweist, dass bei der Platte in verspanntem und erhitzten Betriebszustand optimale Druckspannungsverhältnisse vorliegen und dass mit ihr demzufolge eine erhöhte Haltbarkeit erzielt wird. Der diese Platten aufnehmende Schiebeverschluss soll dabei mit einer Spannvorrichtung ausgerüstet sein, mit welchem diese Platten einfach und schnell einspannbar sind.In contrast, the object of the present invention is a refractory plate according to the type described above create such an outer shape with cheap manufacture has that with the plate in a tensioned and heated operating state optimal compressive stress conditions are present and that with it an increased durability is achieved. The this plate-receiving slide closure is said to have a Clamping device with which these plates are easy and can be clamped quickly.

Erfindungsgemäss ist die Aufgabe durch das Kennzeichen des Anspruchs 1 gelöst.According to the invention the object is achieved by the characterizing part of claim 1.

Für die Verspannung der Platte im Schiebeverschluss ist vorzugsweise eine Spannvorrichtung vorgesehen, welche Spannelemente aufweist, die zwecks Erzielung einer ganzflächigen Auflage an den Seitenflächen der feuerfesten Platte jeweils im Rahmen gelenkig gelagert sind und mindestens zwei der Spannelemente von einem einzigen Verspannmittel gegen die andern beiden Spannelemente verschiebbar geführt sind.For the bracing of the plate in the slide lock is preferred a clamping device is provided, which clamping elements has, in order to achieve a full surface coverage the side surfaces of the refractory plate articulated in the frame are stored and at least two of the clamping elements of a single tensioning device against the other two tensioning elements are guided.

Mit dieser erfindungsgemässen Ausbildung der feuerfesten Platte und der diese festhaltenden Spannvorrichtung wird eine optimale Verspannung und damit ein verbesserte Haltbarkeit der Platte erzielt. Die Verspannung der Platte ist durch die annähernd über die gesamte Plattenlänge erzeugte Kraftbeaufschlagung und durch den mit den gewählten Winkeln auf die Platte wirkenden Kraftlinienverlauf optimiert. Damit gehen die im Betriebszustand in der Platte entstehenden Risse nicht auseinander und ein Ansaugen von Luft durch diese Risse kann weitgehend verhindert werden. Dadurch, dass die Platte keinen Blechmantel aufweist, lässt sie sich kostengünstig fertigen.With this inventive design of the refractory plate and the clamping device holding this will be an optimal one Bracing and thus an improved durability of the plate achieved. The bracing of the plate is due to the approximately entire plate length generated by the force with the selected angles, the line of force acting on the plate optimized. So that go in the operating state in the The resulting cracks do not come apart and are sucked in Air through these cracks can be largely prevented. Thereby, it can be said that the plate has no sheet metal jacket manufacture inexpensively.

Fig. 1 zeigt eine in einem metallischen Rahmen 11 eingespannte feuerfeste Platte 20 mit einer Durchflussöffnung 22. Diese Platte 20 ist in einen nicht näher dargestellten Schiebeverschluss am Ausguss eines Metallschmelze enthaltenden Behälters als Boden- oder Schieberplatte einsetzbar. Ein solcher Schiebeverschluss ist beispielsweise in der Druckschrift EP-B1 0 277 146 ausführlich erläutert und dargestellt. Er wird insbesondere für Stahlschmelze enthaltende Pfannen verwendet, die üblicherweise in Stranggiessanlagen vorgesehen sind.Fig. 1 shows a clamped in a metallic frame 11 Refractory plate 20 with a flow opening 22. This plate 20 is in a sliding closure not shown on Pouring of a container containing molten metal as a bottom or slide plate can be used. Such a slide lock is for example in the document EP-B1 0 277 146 in detail explained and illustrated. It is used especially for molten steel Containing pans used, usually in continuous casting plants are provided.

Die feuerfeste Platte 20 besteht dabei aus einem hitzebeständigen keramischen Material und sie kann einteilig oder aus einem Basismaterial mit mindestens einem hochwertigen Feuerfesteinsatz hergestellt sein, wobei dieser Feuerfesteinsatz vorteilhaft die Durchflussöffnung 22 bildet, durch welche die Stahlschmelze im Betriebszustand der Platte fliesst.The refractory plate 20 consists of a heat-resistant ceramic material and it can be in one piece or from a base material with at least one high-quality refractory insert be made, this refractory insert advantageously the Flow opening 22 forms through which the molten steel in Operating condition of the plate flows.

Im vorliegenden Ausführungsbeispiel weist die Platte 20 eine sechseckige Aussenform mit einer länglichen symmetrischen Ausbildung auf. Beidseitig zur Platten-Längsachse 23 erstrecken sich je zwei mit unterschiedlicher Länge und in einem stumpfen Winkel y zueinander angeordnete Seitenflächen 24, 25, welche als Verspannflächen der Platte 20 im metallischen Rahmen 11 dienen.In the present exemplary embodiment, the plate 20 has a hexagonal outer shape with an elongated symmetrical Training on. Extend on both sides of the longitudinal axis 23 of the plate two each with different lengths and in one blunt Angle y mutually arranged side surfaces 24, 25, which as Bracing surfaces of the plate 20 serve in the metallic frame 11.

Erfindungsgemäss sind die kürzeren Seitenflächen 24 zur Längsachse 23 jeweils in einem Winkel α zwischen 20° und 50°, indessen die längeren Seitenflächen 25 in je einem Winkel β zwischen 10° und 30° zur Längsachse 23 verlaufend angeordnet. Im aktuellen vorteilhaften Ausführungsbeispiel beträgt der Winkel α annähernd 30° und der Winkel β annähernd 14°. Die kürzeren und die längeren Seitenflächen 24, 25 dienen als Verspannflächen der Platte 20 im metallischen Rahmen 11 und bilden dabei unmittelbar aneinander folgend eine quere Kante 26.According to the invention, the shorter side faces 24 are to the longitudinal axis 23 each at an angle α between 20 ° and 50 °, however the longer side surfaces 25 at an angle β between 10 ° and 30 ° to the longitudinal axis 23 extending. In the current advantageous embodiment, the angle α is approximately 30 ° and the angle β approximately 14 °. The shorter and the longer side surfaces 24, 25 serve as bracing surfaces Plate 20 in the metallic frame 11 and thereby form directly consecutive a transverse edge 26.

Zwischen den kürzeren bzw. den längeren Seitenflächen 24 bzw. 25 ist der Plattenrand jeweils mit einer senkrecht zur Längsachse 23 verlaufenden Stirnfläche 27 bzw. 28 gebildet. Diese Stirnflächen 27, 28 weisen eine Länge von annähernd der Hälfte der Plattenbreite auf. Nach Einspannung der Platte 20 im Rahmen 11 sind diese Stirnflächen 27, 28 überdies berührungsfrei und damit ohne Verspannung zum metallischen Rahmen 11 angeordnet. Between the shorter or longer side surfaces 24 or 25 is the plate edge with a perpendicular to the longitudinal axis 23 extending end face 27 and 28 formed. These end faces 27, 28 have a length of approximately half the Plate width. After clamping the plate 20 in the frame 11 these end faces 27, 28 are also contact-free and therefore arranged without tension to the metallic frame 11.

Die Durchflussöffnung 22 ist senkrecht auf der Längsachse 23 angeordnet und weist einen Durchmesser auf, der in etwa einen Drittel bis einen Viertel der Plattenbreite beträgt. In Bezug auf die Längserstreckung der Platte 20 ist diese Durchflussöffnung von der Plattenmitte gegen die kürzeren Seitenflächen 24 hin versetzt angeordnet. Ihr Zentrum liegt dabei annähernd auf der winkelhalbierenden Linie, welche von dem stumpfen Winkel y zwischen der kürzeren und der längeren Seitenfläche 24, 25 gebildet ist. Zwischen der Öffnung 22 und der Stirnfläche 27, welche die beiden kürzeren Seitenflächen 24 verbindet, ist vorzugsweise ein Abstand von cirka einem Drittel der Plattenlänge vorgesehen.The flow opening 22 is arranged perpendicular to the longitudinal axis 23 and has a diameter that is approximately one Is a third to a quarter of the plate width. In relation to the longitudinal extent of the plate 20 is this flow opening offset from the center of the plate against the shorter side faces 24 arranged. Their center lies approximately on the bisector of the angle Line drawn from the obtuse angle y between the shorter and the longer side surface 24, 25 are formed is. Between the opening 22 and the end face 27, which the connects the two shorter side surfaces 24 is preferably one A distance of approximately one third of the plate length is provided.

Der metallische Rahmen 11 besteht aus zwei an sich gleich dimensionierten Rahmenteilen 11', zwei an letzteren gelenkig gelagerten Klemmschuhen 12 sowie aus die beiden Rahmenteile verbindenden Gewindeschrauben 14. Letztere sind jeweils seitlich am einen Rahmenteil 11' schwenkbar gehalten und erstrecken sich durch eine im andern Rahmenteil 11' vorgesehene Bohrung. Die zusammengeschraubten Rahmenteile und die Klemmschuhe 12 bilden eine Öffnung, die der Plattenaussenform entspricht und in welcher die Platte 20 eingespannt werden kann. Der Rahmen 11 mit der darin eingespannten Platte 20 kann in ein Gehäuse des Schiebeverschlusses eingelegt werden, von welchem hierbei bloss zwei Zentrierbolzen 16, 17 veranschaulicht sind. Der eine Rahmenteil 11' hat zur Aufnahme des Bolzens 17 eine entsprechende Bohrung, währenddem der andere Rahmenteil zweckmässigerweise eine Längsnut 18 aufweist, in welcher der Bolzen 16 zentriert ist, damit sich der Rahmen im Gehäuse durch die im Betriebszustand entstehende Erwärmung zumindest in Längsrichtung ausdehnen kann. Nachdem die Platte 20 verschlissen ist, kann diese zusammen mit dem Rahmen aus dem Schiebergehäuse herausgenommen und unter Wiederverwendung des Rahmens eine neue Platte in diesen eingespannt werden. The metallic frame 11 consists of two identical dimensions Frame parts 11 ', two articulated on the latter Clamping shoes 12 as well as connecting the two frame parts Threaded screws 14. The latter are each on the side a frame part 11 'pivotally held and extending through a bore provided in the other frame part 11 '. The screwed together frame parts and the clamping shoes 12 form an opening that corresponds to the outer shape of the plate and in which the plate 20 can be clamped. The frame 11 with the plate 20 clamped therein can in a housing of Sliding closure are inserted, of which only this two centering bolts 16, 17 are illustrated. One part of the frame 11 'has a corresponding one for receiving the bolt 17 Hole, while the other frame part expediently has a longitudinal groove 18 in which the bolt 16 is centered, so that the frame in the housing by the in the operating state expand the resulting heating at least lengthways can. After the plate 20 is worn, it can be put together with the frame removed from the valve body and using the frame a new plate in these are clamped.

Diese erläuterte Ausbildung des Rahmens 11 ermöglicht eine derartige Einspannung der Platte in ihm, dass diese kürzeren und längeren Seitenflächen 24, 25 nahezu über ihre gesamte Länge an den Klemmschuhen bzw. an den Rahmenteilen anliegen, insbesondere auch dann, wenn die Aussenabmessungen der Platte 20 herstellungsbedingt einige Millimeter variieren. Dies kann durch entsprechende Einstellung der Gewindeschrauben 14 sichergestellt werden. Daraus ergibt sich ein weiterer Vorteil der vorliegenden Erfindung insofern, als die Platte an ihren Seitenflächen nicht mit engen Toleranzen hergestellt werden muss.This explained design of the frame 11 enables such Fixing the plate in it that these are shorter and longer Side surfaces 24, 25 to almost the entire length of the Clamp shoes or rest on the frame parts, in particular even if the outer dimensions of the plate 20 are due to production vary a few millimeters. This can be done by appropriate Adjustment of the threaded screws 14 ensured become. This results in a further advantage of the present one Invention insofar as the plate is not on its side surfaces tight tolerances must be established.

Gemäss Fig.2 weist die Platte 20 zwei planparallele Flächen 21, 29 auf, von denen zumindest eine geschliffen ist. Die obere oder die untere Fläche 21, 29 dient dabei als Gleitfläche, welche im Betriebszustand der Platte 20 mit einer ebensolchen zweiten Platte in Gleitkontakt steht. Bei Verschiebung der einen Platte in Richtung ihrer Längsachse 23 werden die Durchflussöffnungen 22 in Offenstellung mehr oder weniger in Überdeckung bzw. ausserhalb dieser in Schliessstellung gebracht. An die der Gleitfläche gegenüberliegenden Fläche 29 schliesst in der Regel eine strichpunktiert dargestellte feuerfeste Hülse 32 an. Für eine einwandfreie Abdichtung zwischen der Platte und dieser Hülse kann die Platte in an sich bekannter Weise im Bereich der Durchflussöffnung eine Aussparung zur Aufnahme der Hülse oder aber einen in die Hülse ragenden Ansatz haben.2, the plate 20 has two plane-parallel surfaces 21, 29, at least one of which is ground. The top or the lower surface 21, 29 serves as a sliding surface, which in Operating state of the plate 20 with such a second plate is in sliding contact. When one plate is moved in the direction The flow openings 22 in its longitudinal axis 23 are in Open position more or less covered or outside this brought into the closed position. To the opposite of the sliding surface Surface 29 generally closes with a dash-dot line Refractory sleeve 32 shown. For a flawless The plate can be sealed between the plate and this sleeve in a manner known per se in the area of the flow opening Recess for receiving the sleeve or one in the sleeve outstanding approach.

Die Aussenform der Platte könnte im Prinzip auch durch weniger oder mehr als sechs Ecken gebildet sein, so zum Beispiel könnte sie achteckig sein, wobei in diesem Falle die zusätzlichen Flächen vorteilhaft jeweils zwischen der kürzeren und der längeren Seitenfläche 24, 25 in annähernd paralleler Anordnung zur Längsachse 23 ausgebildet wären. Auch die Position der Durchflussöffnung 22 zur Längsachse 23 könnte beispielsweise auf der Verbindungslinie zwischen den Kanten 26 oder anderswo liegen. In principle, the outer shape of the plate could also be reduced or more than six corners may be formed, for example they will be octagonal, in which case the additional areas advantageous between the shorter and the longer side surface 24, 25 in an approximately parallel arrangement to the longitudinal axis 23 would be trained. Also the position of the flow opening 22 to the longitudinal axis 23 could, for example, on the connecting line lie between the edges 26 or elsewhere.

Fig.3 zeigt eine in einem Schiebergehäuse 19 integrierte Spannvorrichtung 40 zum lösbaren Festhalten der feuerfesten Platte 20. Diese Spannvorrichtung 40 weist vier in diesem Gehäuse 19 angeordnete Spannelemente 42, 44 auf, welche je eine Spannfläche bilden, die im verspannten Zustand jeweils an eine korrespondierende Seitenfläche 24, 25 der Platte 20 angepresst sind.3 shows a clamping device integrated in a slide housing 19 40 for releasably holding the refractory plate 20. This tensioning device 40 has four arranged in this housing 19 Clamping elements 42, 44, each having a clamping surface form, each in the tensioned state to a corresponding Side surface 24, 25 of the plate 20 are pressed.

Erfindungsgemäss sind diese Spannelemente 42, 44 zwecks Erzielung einer ganzflächigen Auflage an den Seitenflächen 24, 25 der Platte 20 jeweils im Gehäuse 19 gelenkig gelagert und zwei der Spannelemente 44 sind von einem einzigen Verspannmittel gegen die andern beiden Spannelemente 42 hin verschiebbar geführt. Diese dreieckförmig ausgebildeten Spannelemente 42, 44 haben auf ihrer Basisseite jeweils die Spannfläche und sie liegen mit ihrer einen bzw. beiden leicht bombierten Rückseiten an Anschlagflächen 19' des Gehäuses 19 auf. Für die gelenkige Lagerung sind sie mit parallel zur Längsachse 23 ausgerichteten Längsnuten 48 versehen, in denen im Gehäuse 19 vorstehende Bolzen 45, 46 annähernd spielfrei zentriert sind. Diese Spannelemente 42, 44 stellen sich somit beim Verspannen einer Platte 20 dem jeweiligen effektiven Winkel α bzw. β einer Seitenfläche 24, 25 von selbst ein und gewährleisten infolgedessen eine ganzflächige Auflage, die eine gleichmässige Druckverteilung der Spannkraft auf die Platte bewirkt, was die Plattenhaltbarkeit maximiert.According to the invention, these clamping elements 42, 44 are for the purpose of being achieved a full surface support on the side surfaces 24, 25 of the Plate 20 each articulated in the housing 19 and two of the Tensioning elements 44 are opposed by a single tensioning means the other two clamping elements 42 guided out. These triangular clamping elements 42, 44 have on their base side the clamping surface and they lie with their one or both slightly cambered backs on stop surfaces 19 'of the housing 19. For articulated storage they with longitudinal grooves 48 aligned parallel to the longitudinal axis 23 provided, in which in the housing 19 projecting bolts 45, 46 approximately are centered without play. Set these tensioning elements 42, 44 the respective one when clamping a plate 20 effective angle α or β of a side surface 24, 25 by itself and consequently guarantee a full surface coverage, which a uniform pressure distribution of the clamping force on the Plate does what maximizes plate durability.

Die beiden verschiebbaren Spannelemente 44 auf der längeren Seitenfläche 25 sind jeweils über einen Hebel 51 mit einem Kulissenstein 52 verbunden, welcher mit einer quer zur Verschieberichtung der Spannelemente 44, am Gehäuse 19 drehgelagerter Gewindestange 53 in Eingriff stehen. Bei Drehung dieser Gewindestange 53 bewegen sich die beiden Kulissensteine 52 aufgrund der in ihnen vorgesehenen entgegengesetzten Gewindegänge entweder nach innen oder nach aussen. Bei einer Auswärtsbewegung werden die Spannelemente 44 von den Hebeln 51 gegen die Platte 20 gedrückt und letztere damit gespannt, indes bei einer Verschiebung nach innen wird die Platte gelöst. Die Drehung der Gewindestange 53 kann über einen handbetätigten Schlüssel oder aber über eine nicht näher gezeigte automatisch wirkende Einrichtung erfolgen. Die Spannflächen der Spannelemente 42, 44 sind derart bemessen, dass sie sich annähernd über die gesamte Länge mit den mit ihnen in Kontakt stehenden Seitenflächen der Feuerfestplatte überdekken, jedoch vorteilhaft eine etwas geringere Länge als die entsprechenden Platten-Seitenflächen 24, 25 aufweisen und im verspannten Zustand zwischen den Enden dieser Seitenflächen 24, 25 angreifen, ohne die seitlichen Plattenkanten 26, 28' zu berühren, um Rissbildungen bei diesen Kanten zu verhindern.The two sliding clamping elements 44 on the longer one Side surface 25 are each via a lever 51 with a sliding block 52 connected, which with a transverse to the direction of displacement the clamping elements 44, on the housing 19 rotatably mounted threaded rod 53 are engaged. When turning this threaded rod 53 move the two backdrop stones 52 due to the inside of them provided opposite threads either after inside or outside. With an outward movement the Clamping elements 44 pressed by the levers 51 against the plate 20 and the latter tense with it, however, with a postponement the inside of the plate is loosened. The rotation of the threaded rod 53 can be via a manually operated key or via a Automatically acting device, not shown, take place. The clamping surfaces of the clamping elements 42, 44 are dimensioned such that that they are approximately the entire length with those with them cover the contacting side surfaces of the refractory plate, however, advantageously a slightly shorter length than the corresponding ones Have plate side surfaces 24, 25 and in the braced State between the ends of these side surfaces 24, 25 attack without touching the side plate edges 26, 28 ', to prevent cracking at these edges.

Fig.4 und Fig.5 veranschaulichen eine Variante des Spannelementes 42 und der mit diesem zusammenwirkenden Platte 20. Die Platte 20 weist hierbei eine sich über die kürzere Seitenfläche 24 erstreckende Anschrägung 20' auf, die dazu bestimmt ist, dass an ihr ein am Spannelement 42 befestigtes Halteelement 43 aufliegt. Es wird damit ein Herausfallen der Platte 20 verhindert, wenn diese in gelöstem Zustand ist und das Schiebergehäuse 19 und mit ihm die Platte 20 in Längserstreckung gesehen in einer vertikalen Montagestellung befindlich sind.Fig.4 and Fig.5 illustrate a variant of the clamping element 42 and the plate 20 interacting with it Plate 20 has a shorter side surface 24 extending bevel 20 ', which is intended to a holding element 43 fastened to the tensioning element 42 rests on it. It prevents the plate 20 from falling out when it is is in the released state and the valve housing 19 and with the plate 20 seen in a longitudinal extension in a vertical Are in the mounting position.

Selbstverständlich liessen sich noch andere Varianten von Spannvorrichtungen dartun. Zur Erläuterung der Erfindung genügen jedoch die dargelegten Ausführungen.Of course, other variants of clamping devices could also be used do it. To explain the invention, however, are sufficient the statements made.

Die Platte könnte auf ihrer Schmalseite beispielsweise mit einem Synodenband umgeben sein, so dass sie nach dem Gebrauch bei der die Spannelemente lösenden Demontage nicht auseinanderfällt. Im weiteren könnte sie zwecks Isolierung an dieser Schmalseite und/oder an der Rückseite 29 mit einer flexiblen Auflage, z.B. einem Pyrostop-Papier, versehen sein.The plate could, for example, on its narrow side with a Synod tape should be surrounded so that after use the disassembly disassembling the tensioning elements does not fall apart. Furthermore, it could be used for insulation on this narrow side and / or on the back 29 with a flexible pad, e.g. a pyrostop paper.
