Description

Die Erfindung betrifft einen Faserfaltblock mit einem an seiner Rückseite freiliegenden Haltebügel, der an seinen Enden je einen zwischen zwei Faltlagen greifende Schenkel aufweist, wobei sich zwischen den Schenkeln wenigstens eine Stange erstreckt, die die Faltlagen durchstösst und beidseitig in Bohrungen der Schenkel liegt.The invention relates to a fiber folding block with an exposed on its back bracket, each having at its ends a leg extending between two folding layers, at least one rod extending between the legs, which pierces the folding layers and lies on both sides in holes in the legs.

Ein derartiger Faserfaltblock ist in der EP-0 077 608 A1 beschrieben. Bei diesem ist die Stange beidseitig mit Gewinden versehen, auf die ausserhalb der Schenkel Muttern aufgeschraubt sind. Dies ist umständlich. Solche Faserfaltblöcke werden mit dem an ihm angebrachten Haltebügel an den Montageort geliefert. Soll bei der Montage des Faserblocks an einer betreffenden Wand, insbesondere Ofenwand, eine nachträgliche Verdichtung der Faltlagen vorgenommen werden, dann ist dies kaum möglich, da die Muttern nur schlecht in die äussersten Faltlagen eingedrückt werden können. Ein Nachspannen der Muttern am Montageort ist nicht möglich.Such a fiber folding block is described in EP-0 077 608 A1. In this case, the rod is provided with threads on both sides, onto which nuts are screwed outside the legs. This is cumbersome. Such fiber folding blocks are delivered to the installation site with the retaining bracket attached to them. If a subsequent compression of the folded layers is to be carried out when mounting the fiber block on a relevant wall, in particular the furnace wall, then this is hardly possible since the nuts can only be pressed into the outermost folded layers only with difficulty. Retightening the nuts at the installation site is not possible.

Bei dem in der EP 0 077 608 A 1 beschriebenen Faserfaltblock steht das eine Befestigungsende des Haltebügels über den Faserfaltblock hinaus (vgl. auch Literaturstelle «Sprechsaal» Vol. 117, Nr. 9, 1984, Seite 785). Dieses metallische Befestigungsteil liegt also in einer zum Ofeninnenraum hin offenen Fuge. Es wird dadurch im Ofenbetrieb angegriffen.In the fiber folding block described in EP 0 077 608 A1, the one fastening end of the holding bracket projects beyond the fiber folding block (cf. also reference «Talking Room» Vol. 117, No. 9, 1984, page 785). This metallic fastening part is therefore in a joint that is open to the furnace interior. It is attacked in the oven mode.

Aufgabe der Erfindung ist es, einen Faserfaltblock der eingangs genannten Art vorzuschlagen, der sich nachträglich bei der Montage des Faserfaltblocks an einer Wand zur Verdichtung der Faserlagen zusammendrücken lässt und bei dem die Befestigung der Stange am Haltebügel durch eine schraubenfreie Verbindung einfach ist.The object of the invention is to propose a fiber folding block of the type mentioned, which can be compressed later when mounting the fiber folding block on a wall to compress the fiber layers and in which the attachment of the rod to the bracket is simple by a screw-free connection.

Erfindungsgemäss ist obige Aufgabe bei einem Faserfaltblock der eingangs genannten Art dadurch gelöst, dass die Stange ausserhalb der Bohrung des einen Schenkels an ihrem einen Ende eine Abwinklung aufweist und dass die Stange ausserhalb der Bohrung des anderen Schenkels diesen mit ihrem anderen Ende in Längsrichtung frei überragt. Die Stange ist also an keinem ihrer Enden mit einer Schrauben-Mutterverbindung versehen. Die Stange ist durch die Abwinklung des einen Endes in Axialrichtung gehalten. Die Abwinklung ist ihrerseits zwischen dem zugeordneten Schenkel und der diesen überdeckenden äussersten Faltlage gehalten. Am anderen Ende dringt die Stange in die andere äusserste Faltlage ein. Dies ist möglich, da sie dort keine Verbreiterung aufweist. Es kann nun nachträglich bei der Montage eine Verdichtung der Faserlagen vorgenommen werden. Dies erfolgt dadurch, dass die Faserlagen zusammengedrückt werden. Dabei kann sich der eine oder andere Schenkel entsprechend verbiegen und die Stange tritt mit ihrem frei überragenden Ende entsprechend tiefer in die betreffende äusserste Faltlage ein.According to the invention, the above object is achieved in the case of a fiber folding block of the type mentioned at the outset in that the rod has an angled portion at one end outside the bore of one leg and that the rod extends freely beyond the bore of the other leg in the longitudinal direction thereof. The rod is therefore not provided with a screw-nut connection at any of its ends. The rod is held in the axial direction by bending one end. The bend is in turn held between the associated leg and the outermost folded position covering it. At the other end, the rod penetrates into the other extreme folding position. This is possible because there is no widening there. It is now possible to compact the fiber layers later during assembly. This is done by compressing the fiber layers. One or the other leg can bend accordingly and the rod protrudes with its freely projecting end correspondingly deeper into the outermost folded position in question.

In bevorzugter Ausgestaltung der Erfindung ist die Stange an ihrem frei überragenden Ende mit einer Spitze versehen. Dadurch ist das Eindringen in die äusserste Faltlage erleichtert.In a preferred embodiment of the invention, the rod is provided with a tip at its freely projecting end. This facilitates penetration into the outermost folded position.

In weiterer Ausgestaltung der Erfindung sind die Schenkel gegenüber dem Bügel um Biegeachsen biegbar und der Bügel ist zwischen den Biegeachsen durch Umkantungen an seinen Längsrändern versteift. Im Bereich der Biegeachse liegt also diese Versteifung nicht vor. Dadurch ist erreicht, dass sich zum nachträglichen Verdichten der Faltlagen zwar die Schenkel verbiegen lassen, sich dabei jedoch nicht der Bügel selbst verbiegt.In a further embodiment of the invention, the legs are bendable about the bending axis relative to the bracket and the bracket is stiffened between the bending axes by folds on its longitudinal edges. This stiffening is therefore not present in the area of the bending axis. This ensures that the legs can be bent for subsequent compression of the folded layers, but the bracket itself does not bend in the process.

Um zu vermeiden, dass ein den Faserfaltblock seitlich überstehendes Halteteil des Bügels nach einer nachträglichen Verdichtung der Faltlagen den Faserfaltblock noch weiter überragt, ist auf ein solches Halteteil verzichtet. In Weiterbildung der Erfindung ist stattdessen am Bügel ein sich zwischen den Schenkeln erstreckender Schlitz ausgebildet. Mit diesem lässt sich der Haltebügel und damit der Faserfaltblock an einem entsprechenden Zapfen der Wandung an dieser anbringen. Durch den Schlitz ist auch eine Verschieblichkeit gewährleistet, die günstig ist, wenn die Faltlagen bei der Montage nachträglich verdichtet werden. Eine einseitige feste Lagerung eines Faserfaltblocks an der Wand steht einer solchen Verschieblichkeit entgegen.In order to avoid that a holding part of the bracket protruding laterally beyond the fiber folding block protrudes beyond the fiber folding block after a subsequent compression of the folding positions, such a holding part is dispensed with. In a development of the invention, a slot extending between the legs is instead formed on the bracket. With this, the retaining bracket and thus the fiber folding block can be attached to a corresponding pin of the wall. The slot also ensures mobility, which is favorable if the folded layers are subsequently compressed during assembly. One-sided, fixed mounting of a fiber folding block on the wall prevents such mobility.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den weiteren Unteransprüchen und der folgenden Beschreibung eines Ausführungsbeispiels. In der Zeichnung zeigen:

  • Figur 1 einen Faserfaltblock mit Haltebügel,
  • Figur 2 den Haltebügel mit eingesetzter Stange, und
  • Figur 3 den Haltebügel vor dem Umbiegen seiner Schenkel und dem Einsetzen der Stangen.
Further advantageous embodiments of the invention result from the further subclaims and the following description of an exemplary embodiment. The drawing shows:
  • FIG. 1 shows a fiber folding block with a holding bracket,
  • Figure 2 shows the bracket with the rod inserted, and
  • Figure 3 shows the bracket before bending his legs and inserting the rods.

Ein Faserfaltblock 1 weist eine Vielzahl von zickzackförmig verlaufenden Faltlagen auf. Zwischen die beiden äusserstsen Faltlagen 2 und 3 und die jeweils nächste Faltlage greifen Schenkel 4 und 5, die an einem Haltebügel 6 befestigt sind, oder auch einstückig mit diesem ausgebildet sein können. Beispielsweise sind die Schenkel 4 und 5 mit Kanten 7 und 8 von Laschen 9 und 10 des Haltebügels 6 verschweisst.A fiber folding block 1 has a multiplicity of zigzag folding layers. Legs 4 and 5, which are fastened to a holding bracket 6, or can also be formed integrally therewith, grip between the two extreme folding positions 2 and 3 and the respectively next folding position. For example, the legs 4 and 5 are welded to edges 7 and 8 of tabs 9 and 10 of the bracket 6.

Der Haltebügel 6 ist an seinen Längsrändern durch Umkantungen 11 und 12 versteift. Die Laschen 9 und 10 und damit die Schenkel 4 und 5 sind um Biegeachsen 13 und 14 gegenüber dem Bügel 6 im übrigen um etwa 90° abgebogen (vgl. Figur 2). Die Umkantungen 11 und 12 sind jeweils an ihren beiden Enden, die zwischen den Laschen 7 und 8 liegen, mit Schrägen 15 versehen. Dadurch ist auch ein Umbiegen der Schenkel 4 und 5 um mehr als 90° gegenüber dem Haltebügel 6 im übrigen möglich.The bracket 6 is stiffened at its longitudinal edges by folds 11 and 12. The tabs 9 and 10 and thus the legs 4 and 5 are bent about the bending axes 13 and 14 relative to the bracket 6 by about 90 ° (see FIG. 2). The folds 11 and 12 are each provided with bevels 15 at their two ends, which lie between the tabs 7 and 8. This also makes it possible to bend the legs 4 and 5 by more than 90 ° with respect to the retaining bracket 6.

Zwischen den beiden Längsrändern des Haltebügels 6 erstreckt sich ein Schlitz 16, der sich beidseitig in Einstecköffnungen 17 erweitert. Dem Schlitz sind an seinen Längsrändern Umkantungen 16a angeformt, die zu den Einstecköffnungen hin abgeschrägt sind. Die Umkantungen an dem Schlitz führen zur zusätzlichen Versteifung des Haltebügels. An der Wand, an der der Faserblock 1 zu montieren ist, ist ein nicht näher dargestellter Zapfen angeordnet, der sich durch eine der Einstecköffnungen 17 einführen lässt und dann den Haltebügel 6 hintergreift. Durch die an den Einstecköffnungen abgeschrägten Umkantungen 16a wird die Montage des Faserfaltblok kes erleichtert und seine endgültige dichte Anordnung an der Wand erreicht.A slot 16 extends between the two longitudinal edges of the holding bracket 6 and widens on both sides in insertion openings 17. Edges 16a are formed on the longitudinal edges of the slot, which are chamfered towards the insertion openings. The folds on the slot lead to additional stiffening of the bracket. On the wall on which the fiber block 1 is to be mounted, a pin (not shown in detail) is arranged, which can be inserted through one of the insertion openings 17 and then engages behind the retaining bracket 6. The assembly of the fiber folding block is made possible by the bevelled edges 16a at the insertion openings kes relieved and achieved its final tight arrangement on the wall.

Jeder der Schenkel 4 und 5 ist mit drei Bohrungen 18 bzw. 19 versehen. In jede Bohrung 18 und die gegenüberliegende Bohrung 19 ist eine Stange 20 gesteckt. Diese durchstösst dabei die innenliegenden Faltlagen (vgl. Figur 1). Die Stange 20 weist an ihrem einen Ende eine Abwinklung 21 um 90° auf, die von der äussersten Faltlage 2 gegen den Schenkel 4 gehalten ist. Mit ihrem anderen Ende 22 überragt die Stange 20 die entsprechende Bohrung 19 frei (vgl. Figur 2). Das Ende 22 ist durch die Bohrung 19 zwar geführt, jedoch nicht in Axialrichtung an dem Schenkel 5 gehalten. Das Ende 22 ist mit einer Spitze 23 versehen. Das Ende 22 mit der Spitze 23 stösst in die äusserste Faltlage 3.Each of the legs 4 and 5 is provided with three holes 18 and 19, respectively. A rod 20 is inserted into each bore 18 and the opposite bore 19. This pierces the inner folded layers (see FIG. 1). The rod 20 has at one end a bend 21 by 90 °, which is held by the outermost folded position 2 against the leg 4. With its other end 22, the rod 20 projects freely beyond the corresponding bore 19 (cf. FIG. 2). The end 22 is guided through the bore 19, but is not held on the leg 5 in the axial direction. The end 22 is provided with a tip 23. The end 22 with the tip 23 pushes into the outermost folded position 3.

Der vorverdichtete Faserfaltblock 1 wird etwa in folgender Weise an dem Haltebügel 6 bzw. dessen Schenkeln 4 und 5 befestigt:The pre-compressed fiber folding block 1 is fastened in the following manner to the holding bracket 6 or its legs 4 and 5:

Die äusserste Faltlage 2 wird aufgeklappt, was in Figur 1 teilweise dargestellt ist. Der Haltebügel 6 wird mit seinen Umkantungen 11 und 12 so auf den Faserfaltblock 1 aufgesetzt, dass der Schenkel 4 an der der Faltlage 2 nächsten Faltlage anliegt und der Schenkel 5 zwischen die andere äusserste Faltlage 3 und die nächste Faltlage greift. Anschliessend werden die Stangen 20 vom Schenkel 4 her eingeschoben, wobei sie die inneren Faltlagen durchstossen und durch die Bohrungen 19 greifen. Die Abwinklungen 21 stehen dann aussen an dem Schenkel 4 an. Schliesslich wird die äusserste Faltlage 2 umgeklappt und gegebenenfalls gesichert. Dadurch sind über die Abwinklungen 21 die Stangen 20 sicher gehalten.The outermost folded position 2 is opened, which is partially shown in FIG. 1. The retaining bracket 6 is placed with its folds 11 and 12 onto the fiber folding block 1 in such a way that the leg 4 lies against the fold position 2 closest to the fold position 2 and the leg 5 engages between the other outermost fold position 3 and the next fold position. The rods 20 are then pushed in from the leg 4, piercing the inner folded positions and engaging through the bores 19. The bends 21 are then on the outside of the leg 4. Finally, the outermost folded position 2 is folded down and secured if necessary. As a result, the rods 20 are securely held over the bends 21.

Die Anbringung des Faserfaltblocks 1 mit dem Haltebügel 6 an der Montagewand kann in folgender Weise vorgenommen werden:The fiber folding block 1 can be attached to the mounting wall using the holding bracket 6 in the following manner:

Der Haltebügel 6 wird mit einer der Einstecköffnungen 17 auf einen Zapfen der Montagewand gesteckt und demgegenüber verschoben. Anschliessend lässt sich dann eine weitere Verdichtung der Faltlagen vornehmen. Dafür wird auf die äusserste, freie Faltlage 2 oder 3 fest gedrückt. Hierbei kann sich der Schenkel 4 oder 5 weiter um die Biegeachse 13 bzw. 14 verbiegen. Wegen der Grossflächigkeit der Schenkel 4 und 5 erfolgt eine gleichmässige Druckverteilung. Die Stangen 20 behindern eine solche nachträgliche Verbiegung der Schenkel 4 und 5 nicht. Die Enden 22 werden mit ihren Spitzen 23 bei einer Verbiegung der Schenkel 4 und 5 entsprechend tiefer in die äusserste Faltlage 3 eindringen.The bracket 6 is inserted with one of the insertion openings 17 on a pin of the mounting wall and moved against it. A further compression of the folded layers can then be carried out. To do this, press firmly on the outermost, free folded position 2 or 3. Here, the leg 4 or 5 can bend further about the bending axis 13 or 14. Because of the large area of the legs 4 and 5 there is an even pressure distribution. The rods 20 do not hinder such subsequent bending of the legs 4 and 5. The ends 22 will penetrate deeper into the outermost folded position 3 with their tips 23 if the legs 4 and 5 bend.
