Abstract

In a method for maintaining poke-hole spacings in a ceiling of tunnel furnaces in the ceramic industry, which ceiling consists of support stones, arranged in support stone rows, with circumferential support strips and filling stones inserted in between, the poke-hole spacings of the individual tunnel furnaces varying because of the different bundle dimensions, the support stones of individual support stone rows or the support stones of all support stone rows are, to maintain different poke-hole spacings, turned by 90 DEG in such a manner that either the shorter wide side or the longer long side of the rectangular support strip of the support stones comes into effect in the preparation of the poke-hole spacings. A support stone for implementing this method is fastened, with a two-part bow-shaped suspension device which is rotatable in itself, to a support rail laid above the tunnel furnace. The support stone consists of a four-cornered shaft and a support strip which is arranged on the lower shaft, runs around the shaft and is of rectangular design in the base, the long sides being longer than the wide sides. The bow-shaped suspension device engages in notches which are arranged opposite in the upper region of the shaft and which are arranged in diagonally opposite corners of the four-cornered shaft.

Description

Die in der Zeichnung dargestellte Decke 1 besteht aus Tragsteinen 2 und zwischen den Tragsteinen 2 angeordneten Füllsteinen 3. Die Tragsteine 2 sind in Tragsteinreihen R mittels einer in sich drehbaren, zweiteiligen bügelförmigen Aufhängung 4, wie sie in der DE-PS 33 16555 dargestellt ist, an einer über die Breite des Tunnelofens (nicht dargestellt) gelegten Tragschiene 5 befestigt. In jeder Tragsteinreihe R ist zwischen den Tragsteinen 2 jeweils ein Füllstein angeordnet, so daß nur jeder zweite Stein ein Tragstein 2 ist. The ceiling 1 shown in the drawing consists of supporting stones 2 and arranged between the supporting stones 2 Filling stones 3. The Support stones 2 are in rows R by means of a rotatable, two-part Bow-shaped suspension 4, as shown in DE-PS 33 16 555, on one Fastened over the width of the tunnel oven (not shown) laid support rail 5. In each row of bearing stones R, a filling stone is arranged between the bearing stones 2, so that only every second stone is a bearing stone 2.

Die Tragsteine 2 (Fig. 1-3) bestehen jeweils aus einem viereckigen Schaft 6 und einer am unteren Schaft 6 angeordneten, um den Schaft 6 umlaufenden Tragleiste 7, die in der Grundfläche rechteckig ausgebildet ist, so daß die Längsseiten 7a länger als die Breitseiten 7b sind. The supporting stones 2 (Fig. 1-3) each consist of a square Shank 6 and one arranged on the lower shank 6 and encircling the shank 6 Support bar 7, which is rectangular in the base, so that the longitudinal sides 7a are longer than the broad sides 7b.

Die Tragsteine 2 besitzen im oberen Bereich des Schaftes 6 Einkerbungen 8 und 9, die in diagonal gegenüberliegende Ecken des Schaftes 6 angebracht sind und in die der untere drehbare Teil 4a der Aufhängung 4 eingreift, während der obere Teil 4b der Aufhängung 4 mit der Tragschiene 5 zusammenwirkt In F i g. 3 ist die Drehbarkeit der einzelnen Tragsteine dargestellt, indem der untere Teil 4a der Aufhängung 4 um 90" gedreht wird, so daß in ungedrehter Stellung die kürzeren Breitseiten 7b und nach Drehung um 90" die längeren Längsseiten 7a zur Wirkung kommen. Bei der Drehung der Tragsteine 2 kann natürlich auch in umgekehrter Weise verfahren werden, indem in ungedrehter Stellung die längeren Längsseiten 7a und nach Drehung um 90D die kürzeren Breitseiten 7b zur Wirkung kommen.The support stones 2 have 6 notches in the upper region of the shaft 8 and 9, which are mounted in diagonally opposite corners of the shaft 6 and in which the lower rotatable part 4a of the suspension 4 engages, while the upper Part 4b of the suspension 4 interacts with the support rail 5 in FIG. 3 is the Rotatability of the individual bearing blocks shown by the lower part 4a of the suspension 4 is rotated by 90 ", so that in the unturned position the shorter broad sides 7b and after turning 90 "the longer longitudinal sides 7a come into effect Rotation of the bearing blocks 2 can of course also be done in the opposite way, in that in the unturned position the longer long sides 7a and after rotation by 90D the shorter broad sides 7b come into effect.

In den Fig. 4 - 6 ist jeweils eine Decke 2 dargestellt, bei der die Füllsteine 3 auf die Tragleisten 7 der Tragsteine 2 aufliegen und somit die zwischen den Tragsteinen 2 bestehenden Zwischenräume ausfüllen. Zur Anordnung von Brennern (nicht dargestellt) sind in den Füllsteinen 3 Schürlöcher S angebracht, die die Brenner aufnehmen. Die Abstände a, b und c zwischen den Schürlöchern S richten sich nach der Breite der durch den Tunnelofen transportieren Gutstapel (nicht dargestellt), da die in den Schürlöchern S befindlichen Brenner immer nur in die Zwischenräume zwischen den Gutstapeln feuern. Da die Breite bei meist allen Gutstapeln variiert, muß bei der Auslegung und Planung der Tunnelöfen die Breite der Gutstapel derart berücksichtigt werden, daß die Abstände a, b und c zwischen den Schürlöchern S entsprechend der Breite der Gutstapel eingeplant und eingehalten werden. Bei der Planung der Decke 1 wird davon ausgegangen, daß die Tragsteine 2 und die Füllsteine 3 immer gleiche Abmessungen besitzen. 4-6 each show a ceiling 2 in which the Filling blocks 3 rest on the support strips 7 of the support blocks 2 and thus the between fill the supporting stones 2 existing spaces. For the arrangement of burners (not shown) in the filler stones 3 drilling holes S are made, which the Pick up burner. The distances a, b and c between the poking holes S are aligned according to the width of the stack of goods transported through the tunnel kiln (not shown), because the burners located in the poking holes S only ever go into the gaps fire between the stacks of goods. Since the width varies for most of the stacks of goods, When designing and planning the tunnel kilns, the width of the stack of goods must be such be taken into account that the distances a, b and c between the poking holes S accordingly the width of the stack of goods are planned and adhered to. When planning the Ceiling 1 it is assumed that the supporting stones 2 and the filler stones 3 always have the same dimensions.

Die Fig. 4 offenbart eine Decke 1, bei der der Abstand zwischen den Schürlöchern S das Maß a aufweist. Fig. 4 discloses a ceiling 1, in which the distance between the Poking holes S has the dimension a.

Hier sind die Tragsteine 2 so angeordnet, daß die kürzeren Breitseiten 7b der Tragleiste 7 bei der Erstellung des Maßes a zur Wirkung kommen.Here the supporting stones 2 are arranged so that the shorter broad sides 7b of the support bar 7 come into effect when creating the dimension a.

Die F i g. 5 zeigt eine Decke 1, bei der die Tragsteine 2a um 90" gegenüber dem Tragstein 2 gedreht sind, so daß nunmehr die kürzere Breitseite 7b und die längere Längsseite 7a der Tragleiste 7 das Maß des Abstandes b mitgestaltet. Der Abstand b ist wegen der längeren Längsseite 7a größer als der Abstand a. The F i g. 5 shows a ceiling 1 in which the supporting stones 2a by 90 " are rotated relative to the support block 2, so that now the shorter broad side 7b and the longer longitudinal side 7a of the support strip 7 helps shape the dimension of the distance b. The distance b is greater than the distance a because of the longer longitudinal side 7a.

In der Fig. 6 ist eine Decke dargestellt, bei der alle Tragsteine 2a um 90" gegenüber den Tragsteinen 2 gedreht sind, so daß ausschließlich die längere Längsseite 7a der Tragleiste 7 bei der Erstellung des Maßes c zum Tragen kommt. Der Abstand c ist größer als die Abständeaundb. In Fig. 6 a ceiling is shown in which all supporting stones 2a are rotated by 90 "with respect to the supporting stones 2, so that only the longer Long side 7a of the support bar 7 comes into play when creating the dimension c. The distance c is greater than the distances a and b.

Durch Drehung der Tragsteine 2 um 90" können in Kombination verschiedene Abstände a, b und c zwischen den Schürlöchern S erstellt werden, wobei die Abmessungen der Tragsteine 2 und Füllsteine 3 gleich bleiben. By rotating the supporting stones 2 by 90 ", different Distances a, b and c between the poking holes S are created, with the dimensions the supporting stones 2 and filler stones 3 remain the same.

Support stone for performing the method according to claim 1, with a rotatable, two-part bow-shaped suspension on one above the Tunnel furnace is attached to the support rail, and which consists of a square shaft and a support strip arranged on the lower shaft and encircling the shaft, the bow-shaped suspension in the upper area of the shaft opposite one another attached notches engages, characterized in that the notches (8,9) in diagonally opposite corners of the square shaft (6) attached are and that the support bar (7) is rectangular in the base, wherein the long sides (7a) are longer than the broad sides (7b).

The invention relates to a method for maintaining poking hole spacings in a ceiling of tunnel kilns of the ceramic industry with the generic term of Claim 1 listed features. The invention also relates to a support stone for carrying out this method with the preamble of the claim 2 features described.

DE-GM 8406 679 discloses a ceiling for ceramic kilns, made of refractory bricks arranged in a row and attached to the support rails and there is refractory filler bricks arranged between them, in each Bearing stone row only every second stone is a bearing stone, while the one in between inlaid filling stones from circumferential support strips located on the supporting stones being held. The supporting stones are attached to the mounting rails by suspensions. For this purpose, the suspensions act on the one hand on the mounting rails and on the other hand they engage in notches that run parallel to each other, which each bearing stone on two opposite sides in the upper part of the shaft.

To attach burners between the rows of bearing stones in The filling stones arranged potholes that receive the burners. So that the burners exactly in the gaps between the good packages conveyed through the furnace can fire, the distances between the pots must be and thus also between the rows of bearing stones when building a tunnel kiln were precisely planned and adhered to will. Since the package dimensions do not match for every tunnel kiln, the Pit hole spacing and thus also the spacing between the rows of bearing stones in the Each tunnel oven has a different ceiling. For the ceiling according to DE-GM 8406 679 therefore occurs the disadvantage that to create different distances between the rows of bearing stones or digging holes, filling stones with different dimensions must be present. The production of the many varieties required as a result However, filler blocks are associated with production engineering expense, as for everyone different filler stone a basic shape must be available, which is very expensive is. In addition, the storage of the many types of filling stones requires an even larger one Expenditure.
