Abstract

The method involves extrusion pressing clay to form longitudinal and transverse walls (3-5) and bars (6,6',7), cutting into lengths the height of the brick, drying and firing. At least one of the longitudinal (6,6') or transverse (7) bars is varied in thickness, length or shape before firing, by mechanical abrasion. The abrasion may be boring, sawing, grinding, milling or husking. Preferably only part of the bar is abraded. An Independent claim is included for a ventilation brick.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Lochziegels mit vier Außenwänden, nämlich mit zwei Längswänden und mit zwei Querwänden, sowie mit Längsstegen und mit Querstegen, bei dem man Lehm bzw. Ton strangpresst, in der Ziegelhöhe entsprechenden Abständen, schneidet, trocknet und dann brennt. Die vorliegende Erfindung betrifft weiters einen Lochziegel mit vier Außenwänden, nämlich mit zwei Längswänden und mit zwei Querwänden, sowie mit Längsstegen und mit Querstegen.The present invention relates to a method for manufacturing a perforated brick with four outer walls, namely with two longitudinal walls and with two transverse walls, as well as with longitudinal webs and with crossbars, where you extrude clay or clay, spacing corresponding to the brick height, dries and then burns. The present invention relates to furthermore a perforated brick with four outer walls, namely with two longitudinal walls and with two transverse walls, as well as with Longitudinal bars and with transverse bars.

Es sind Ziegel aus gebrannten Lehm bzw. Ton als Hochlochziegel oder Langlochziegel mit den unterschiedlichsten Lochbildern bekannt. Diese Lochbilder werden durch die Längsstege und Querstege gebildet. Sie erstrecken sich über die Ziegellänge und Ziegelbreite und dienen dazu, die Wärmeleitfähigkeit des Ziegels möglichst gering zu halten. Man bevorzugt daher solche Lochbilder, wo der Weg zwischen den beiden Längswänden entlang der Längsstege und Querstege mäanderförmig und somit sehr lang ist. Hergestellt werden solche Ziegel, indem man Lehm bzw. Ton strangpresst, in der Ziegelhöhe entsprechenden Abständen schneidet, trocknet und dann brennt.They are bricks made of fired clay or clay as perforated bricks or elongated brick with a wide variety of hole patterns known. These hole patterns are through the longitudinal webs and crossbars formed. They extend over the length of the brick and brick width and serve the thermal conductivity to keep the brick as low as possible. One prefers hence such hole patterns where the path between the two Longitudinal walls along the longitudinal webs and transverse webs meandering and is therefore very long. Such bricks are made by extruding clay or clay at brick height cuts, dries and then burns at appropriate intervals.

Beim Strangpressen muss man eine gewisse Mindeststärke (etwa 5 mm) bei den Längsstegen und den Querstegen einhalten, andernfalls wird die Zuverlässigkeit der Herstellung beeinträchtigt. Wie im Rahmen der vorliegenden Erfindung gefunden wurde, ist diese Mindeststärke in statischer Hinsicht oft gar nicht notwendig. Eine Verringerung der Wandstärke wäre daher wünschenswert, weil dadurch die Wärmeleitfähigkeit herabgesetzt würde.When extruding you have to have a certain minimum thickness (approx. 5 mm) with the longitudinal webs and the transverse webs, otherwise the reliability of the manufacture will be impaired. As found in the present invention statically, this minimum strength is often unnecessary. A reduction in the wall thickness would therefore be desirable because this reduces the thermal conductivity would.

Es ist Aufgabe der vorliegenden Erfindung, das Verfahren der eingangs genannten Art so zu verbessern, dass Ziegel mit geringeren Wandstärken bei den Längsstegen und den Querstegen hergestellt werden können. It is an object of the present invention, the method of the type mentioned in the introduction so that bricks with lower wall thicknesses for the longitudinal bars and cross bars can be produced.

Diese Aufgabe wird durch ein Verfahren der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass man vor und/oder nach dem Brennen zumindest einige der Längsstege und/oder der Querstege durch eine mechanische abrasive Bearbeitung in ihrer Dicke, Länge und/oder Form verändert.This task is accomplished by a method of the type mentioned at the beginning Art solved according to the invention in that one before and / or after firing at least some of the longitudinal webs and / or the Cross bars through mechanical abrasive processing in their thickness, length and / or shape changed.

Erfindungsgemäß werden also die innen liegenden Längsstege und Querstege mechanisch nachbearbeitet. Auf diese Weise kann deren Dicke optimal gewählt werden, ohne Rücksicht auf die Erfordernisse der Extrusion. Es ist auch möglich, deren Form zu verändern, also zum Beispiel Löcher vorzusehen oder Abschnitte mit unterschiedlicher Dicke.According to the invention, the inner longitudinal webs and cross bars mechanically reworked. That way whose thickness can be chosen optimally, regardless of the Extrusion requirements. It is also possible to change their shape to change, for example to provide holes or sections with different thickness.

Vorzugsweise erfolgt also die Bearbeitung der Längsstege und/oder der Querstege nur über einen Teil ihrer Länge.The longitudinal webs are therefore preferably machined and / or the crossbars only over part of their length.

Die mechanische abrasive Bearbeitung kann Bohren, Fräsen, Schleifen, Sägen oder Schälen sein.Mechanical abrasive processing can be drilling, milling, Grinding, sawing or peeling.

Ein erfindungsgemäßer Ziegel ist dadurch gekennzeichnet, dass zumindest einige der Längsstege und/oder der Querstege in Extrusionsrichtung Abschnitte unterschiedlicher Dicke aufweisen.A brick according to the invention is characterized in that that at least some of the longitudinal webs and / or the transverse webs have sections of different thickness in the extrusion direction.

Anhand der beiliegenden Figuren wird die vorliegende Erfindung näher erläutert. Es zeigt: Fig. 1 einen Ziegel in Draufsicht vor der mechanischen abrasiven Bearbeitung; und Fig. 2 einen Teil dieses Ziegels in vergrößerter Ansicht nach der mechanischen abrasiven Bearbeitung.The present invention is based on the attached figures explained in more detail. 1 shows a brick in plan view before mechanical abrasive processing; and Fig. 2 part of this brick in an enlarged view according to the mechanical abrasive processing.

Der Ziegel 1 weist zwei Längswände 2, 3 und zwei Querwände 4, 5 auf. Zwischen den Längswänden 2, 3 und parallel zu diesen befinden sich mehrere Längsstege 6, die über Querstege 7 miteinander bzw. mit den Längswänden 2, 3 verbunden sind. Die Querstege 7 sind gegeneinander versetzt angeordnet, sodass die Wärme von der einen Längswand 2 zur anderen Längswand 3 nur über einen entsprechend langen, mäanderförmigen Weg (Pfeil 8) gelangen kann. Die Querwände 4, 5 haben eine Kontur mit Vorsprüngen und Vertiefungen, so dass ein weiterer Ziegel, der links oder rechts angesetzt wird, sich automatisch zentriert. The brick 1 has two longitudinal walls 2, 3 and two transverse walls 4, 5 on. Between the longitudinal walls 2, 3 and parallel to them there are a plurality of longitudinal webs 6, which are connected via transverse webs 7 are connected to one another or to the longitudinal walls 2, 3. The Crosspieces 7 are offset from one another, so that the heat from one longitudinal wall 2 to the other longitudinal wall 3 only via a correspondingly long, meandering path (Arrow 8). The transverse walls 4, 5 have a contour with protrusions and depressions so that another brick, which is placed on the left or right, automatically centered.

Dieser Ziegel 1 wird nun mechanisch bearbeitet. Dies kann zum Beispiel dadurch geschehen, dass man mit einer Trennscheibe in den Zwischenraum zwischen jeweils zwei Längsstegen 6 bzw. zwischen einer Längswand 2, 3 und dem benachbarten Längssteg 6 hineinfährt. Dadurch werden die Querstege 7 oben bzw. unten weggeschliffen, und die Wandstärke der Längsstege wird reduziert. Das Ergebnis ist in Fig. 2 zu sehen. Die Längsstege 6 haben oben einen Abschnitt 6' mit verringerter Wandstärke, und die Querstege 7 enden mit Abstand vor der Oberseite des Ziegels 1.This brick 1 is now machined. This can for example by doing that with a cutting disc in the space between two longitudinal bars 6 or between one longitudinal wall 2, 3 and the adjacent one Longitudinal web 6 drives in. As a result, the crosspieces 7 are at the top or ground away below, and the wall thickness of the longitudinal webs is reduced. The result can be seen in FIG. 2. The Longitudinal webs 6 have a section 6 'with reduced at the top Wall thickness, and the crossbars 7 end at a distance in front of the Top of the brick 1.
