Description

Kern zum Herstellen von Hohlziegeln Es ist an sich bekannt, allseitig geschlossene Hohlziegel in der Weise herzustellen, daß auf der Strangpresse um einen oder mehrere Kerne Hohlstränge hergestellt werden. an deren Seiten gleichzeitig die zum Verschließen benötigten Platten mit angefertigt werden. Ferner ist bekannt, bei allseitig geschlossenen Hohlsteinen Schmauchöffnungen vorzusehen, durch die während d, -s Brennens die Brandgase hindurchströmen können.Core for the production of hollow bricks It is known per se, on all sides produce closed hollow bricks in such a way that on the extruder to one or several cores hollow strands are made. on their sides at the same time the plates required for sealing are also made. It is also known for hollow stones closed on all sides to provide smoke openings through which during the burning the fire gases can flow through.

Gegenüber diesen bekannten Vorrichtungen zum Herstellen von Hohlziegeln mit Schmauchöffnungen sollen nach der vorliegenden Erfindung in einem Arbeitsgang zugleich b°i der Herstellung des Hohlziegels durch das Anbringen von Ausbuchtungen am Kernstück auch die Schmauchöffnungen mit hergestellt werden. Dies wird dadurch erreicht, daß die Schmauchöffnungen, die den Hohlziegel der Länge nach durchziehen, an den Seiten des Verschlußstückes .angebracht sind, so daß beim Verschließen der Hohlziegelstirnenden diese öffnungen offen bleiben und die Brandgase jederzeit entweichen können.Compared to these known devices for the production of hollow bricks with smoke outlets should according to the present invention in one operation at the same time b ° i the production of the hollow brick by adding bulges the smoke openings are also made at the core. This is because of this achieved that the smoke openings that run through the length of the hollow brick, Are .attached on the sides of the closure piece, so that when closing the Hollow brick ends these openings remain open and the fire gases escape at any time can.

Der auf diesen Vorrichtungen hergestellte Stein ist in beiliegender Zeichnung dargestellt.The stone made on these devices is enclosed Drawing shown.

Durch das Mundstück einer Strangpresse mit den entsprechend geformten Kernen b tritt der Hohlziegelstrang a, der gleichzeitig seitwärts die Verschlußplättchen g mitführt, die durch den Zwischenraum c von der eigentlichen Ziegelmasse a beinahe abgetrennt werden und nur mehr an den schwachen Ansatzstücken i mit dem Hohlziegel zusammenhängen. Im Verlaufe des Arbeitsvorganges werden diese Plättchen g von einer mit Haltestiften k versehenen Tragplatte/ gefaß,t und von einem Drahte von dem Ziegel abgeschnitten und auf ihrer den Verschlußlöchern b entsprechenden Länge zugeschnitten. Nach genügendem Vorschub wird der einzelne Ziegel um 9o° gedreht, die Halteplatten f weichen genügend nach links und rechts aus und pressen die Verschlußplatten auf die Löcher b, wobei sich durch ihre konische Form bei i diese Plättchen mit dem Ziegelmaterial aufs innigste verbinden. Da aber die Plättchen quadratisch bzw. rechteckig geformt sind, die Hohlräume b aber vier das Quadrat oder Rechteck überragende segmentartige üffnungen d haben, .entstehen bei d Schmauchöffnungen zum Entweichen der Feuchtigkeit beim Trocknen und des Dampfes beim Brennen. Durch das Anordnen dieser über die Verschlußplättchen ragenden öffnungen wird nicht nur gutes Austrocknen, sondern auch restloses Durchdringen der Brennwärme durch den ganzen Hohlziegel gewährleistet, zum Unterschied von den allseitig geschlossenen Hohlziegeln, die besonders an der verschlossenen Stirnfläche ungleich brennen, manchmal sogar erheblich verziehen, da in den ganz geschlossenen Ecken die Feuchtigkeit nicht restlos entweichen kann.The hollow brick strand a passes through the mouthpiece of an extruder with the correspondingly shaped cores b, which at the same time carries sideways the locking plates g, which are almost separated from the actual brick mass a by the space c and are only connected to the hollow brick at the weak attachments i. In the course of the working process, these plates g are cut off from the brick by a support plate / vessel t provided with retaining pins k and by a wire and cut to their length corresponding to the locking holes b. After a sufficient advance, the individual brick is rotated by 90 °, the retaining plates f give way to the left and right enough and press the locking plates onto the holes b, whereby these plates connect intimately with the brick material due to their conical shape at i. However, since the platelets are square or rectangular in shape, the cavities b have four segment-like openings d projecting over the square or rectangle, smoke openings are created at d to allow moisture to escape during drying and the steam during firing. By arranging these openings protruding over the locking plate, not only good drying out, but also complete penetration of the burning heat through the entire hollow brick is ensured, in contrast to the hollow bricks closed on all sides, which burn unevenly, especially on the closed end face, sometimes even considerably warped because in the completely closed corners the moisture cannot completely escape.

Daß bei der Plättchenherstellung auch gleich eine Mörtelnuth gebildet wird, ist ein weiterer Vorteil des neuen Ziegels.That a mortar nut was formed when the platelets were made is another advantage of the new brick.
