Abstract

The brick (1) has four outer walls (2,3) and longitudinal (6) and transverse (6) bars. Holes (10,11) are formed in the transverse walls or the transverse bars. The holes are shorter than the corresponding brick length and are not wider than the spacing between adjacent longitudinal walls or bars. Preferably, the holes are slits and are only formed in part of the transverse walls or bars. An Independent claim is included for a method for manufacturing the brick.

Description

Die vorliegende Erfindung betrifft 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 perforated brick four outer walls, namely with two longitudinal walls and with two Cross walls, as well as with longitudinal webs and with cross webs.

Sie betrifft weiters ein Verfahren zur Herstellung eines Ziegels, bei dem man Lehm bzw. Ton strangpresst, in der Ziegelhöhe entsprechenden Abständen schneidet, trocknet und dann brennt.It also relates to a method for producing a Brick, in which clay or clay is extruded, at brick height cuts, dries and then appropriate intervals burns.

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.

Es ist Aufgabe der vorliegenden Erfindung, die Wärmeleitfähigkeit solcher Ziegel noch weiter herabzusetzen.It is an object of the present invention, the thermal conductivity to lower such brick even further.

Diese Aufgabe wird durch einen Lochziegel der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass in den Querwänden oder in den Querstegen Löcher vorgesehen sind, die kürzer sind als die entsprechende Dimension des Ziegels, und die höchstens so breit sind wie der Abstand benachbarter Längswände oder Längsstege.This task is achieved by a perforated brick of the type mentioned Art solved according to the invention in that in the transverse walls or holes are provided in the crossbars are shorter than the corresponding dimension of the brick, and which are at most as wide as the distance between neighboring ones Longitudinal walls or webs.

Durch die Löcher in den Querstegen bzw. Querwänden wird die Wärmeleitung an diesen Stellen unterbrochen, sodass die Wärmeleitfähigkeit insgesamt herabgesetzt wird. Die Löcher sollen kürzer sein als die entsprechende Dimension des Ziegels, das heißt die Querwände bzw. Querstege dürfen nicht vollständig durchtrennt sein, damit die mechanischen Eigenschaften des Ziegels nicht allzu stark verschlechtert werden. (Die "entsprechende Dimension" ist also bei Hochlochziegeln die Höhe und bei Langlochziegeln die Länge.) Es ist von der Herstellung her am einfachsten, die Querstege oben und unten zu entfernen und nur in der Mitte stehen zu lassen. Bei den außen liegenden Querwänden können die Löcher leicht an beliebigen Stellen angebracht werden.Through the holes in the crosspieces or cross walls Thermal conduction interrupted at these points, reducing the thermal conductivity is reduced overall. The holes are supposed to be shorter than the corresponding dimension of the brick, that is, the transverse walls or crosspieces must not be complete be severed so the mechanical properties the brick should not deteriorate too much. (The "Corresponding dimension" is therefore the case for perforated bricks Height and the length for elongated brick.) It is from the manufacture easiest way, the crossbars above and below remove and leave only in the middle. With the outside lying transverse walls, the holes can be easily on any Places are attached.

Vorzugsweise sind die Löcher als Schlitze ausgebildet. Diese Schlitze können sich bis zur Oberseite oder der Unterseite des Ziegels erstrecken.The holes are preferably designed as slots. These slots can extend up to the top or bottom extend the brick.

Es ist zweckmäßig, wenn nur ein Teil der Querwände und Querstege mit Löchern versehen ist. Ziegel sind erfahrungsgemäß nicht gleichmäßig über ihren Querschnitt mechanisch belastet. Zumeist ist die Belastung innen höher als außen. Wenn nur ein Teil der Querstege und Querwände mit Löchern versehen ist, wird man den Ziegel so einsetzen, dass die Löcher an der Außenseite zu liegen kommen. Es ist dann lediglich der Bereich des Ziegels geschwächt, der statisch ohnehin nur weniger belastet ist, so dass solch ein Ziegel in mechanischer Hinsicht einem Ziegel ohne Löcher in den Querwänden bzw. Querstegen praktisch gleichwertig ist, obwohl er bezüglich der Wärmeleitfähigkeit weit überlegen ist.It is useful if only part of the transverse walls and Crossbars are provided with holes. Experience has shown that bricks are not mechanically loaded evenly across their cross-section. The load is usually higher inside than outside. If only some of the crossbars and cross walls have holes the brick will be inserted so that the holes on the Come to rest on the outside. Then it's just the area weakened the brick, the statically less so anyway is loaded, so such a brick in mechanical Regarding a brick without holes in the transverse walls or Crossbars is practically equivalent, although it is regarding is far superior to thermal conductivity.

Die Ziegel können als Hochlochziegel oder als Langlochziegel ausgeführt sein.The brick can be used as a perforated brick or as an elongated brick be executed.

Um solche Ziegel herzustellen, wandelt man das eingangs genannte Verfahren dahingehend ab, dass man vor und/oder nach dem Brennen in den Querwänden oder Querstegen Löcher bohrt, schleift, fräst oder schneidet.To produce such bricks, you change the above Process from the fact that one before and / or after holes in the transverse walls or crosspieces after burning, grinds, mills or cuts.

Anhand der beiliegenden Figuren wird die vorliegende Erfindung näher erläutert. Es zeigt: Fig. 1 einen erfindungsgemäßen Ziegel in Draufsicht; Fig. 2 eine Ansicht gemäß Pfeil II in Fig. 1; und Fig. 3 einen Schnitt entlang der Linie III-III in Fig. 1.The present invention is based on the attached figures explained in more detail. 1 shows a device according to the invention Top view of bricks; Fig. 2 is a view according to arrow II in Fig. 1; and FIG. 3 shows a section along the line III-III in Fig. 1.

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.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).

Die Querwände 4, 5 haben eine Kontur mit Vorsprüngen 15, zwischen denen sich Vertiefungen befinden, so dass ein weiterer Ziegel, der links oder rechts angesetzt wird, sich automatisch zentriert.The transverse walls 4, 5 have a contour with projections 15, between which there are depressions, so that another Brick that is placed on the left or right automatically centered.

Erfindungsgemäß sind in den Querwänden 4, 5 und/oder in den Querstegen 7 Löcher 9, 10, 11 (siehe Fig. 2 und 3) vorgesehen. In die Querwände 4, 5 können leicht schlitzförmige Löcher 9 (siehe Fig. 2) an beliebigen Stellen gefräst werden. Bei den Querstegen 7 ist es am einfachsten, oben und unten ein Stück mit einer Trennscheibe wegzuschleifen, sodass sich oben und unten schlitzförmige Löcher 10 bzw. 11 (siehe Fig. 3) ergeben. Es ist aber natürlich ebenso möglich, in den Querwänden 4, 5 Löcher vorzusehen, die bis ganz nach oben oder unten durchgehen, oder in den Querstegen 7 Löcher, die irgendwo in der Mitte liegen.According to the invention in the transverse walls 4, 5 and / or in the Cross bars 7 holes 9, 10, 11 (see Fig. 2 and 3) are provided. Slightly slit-shaped holes can be made in the transverse walls 4, 5 9 (see Fig. 2) can be milled at any point. It is easiest for the crossbars 7, above and below to grind away a piece with a cutting disc so that slot-shaped holes 10 and 11 above and below (see Fig. 3) result. But it is of course also possible in the To provide transverse walls 4, 5 holes that go all the way up or go through below, or in the crossbars 7 holes that somewhere in the middle.

Wie man in den Fig. 2 und 3 sieht, sind die Löcher 9, 10, 11 nur auf einer Seite der Längsmittelebene des Ziegels vorgesehen (auf der linken Seite, so wie in den Fig. 2 und 3 gesehen). Diese Seite ist natürlich statisch weniger belastbar. Die rechte Seite dient daher zur Tragfähigkeit, die linke Seite zur Wärmeisolation.As can be seen in FIGS. 2 and 3, the holes 9, 10, 11 provided only on one side of the longitudinal median plane of the brick (on the left, as seen in Figs. 2 and 3). Of course, this site is structurally less resilient. The right side is therefore used for load-bearing capacity, the left Thermal insulation page.
