Abstract

The designed fracture is for asbestos cement panels, flat or more esp. corrugated, and esp. as used on roofs. These have to be capped at the corners to permit a clean and well-sealed panel coverage. The perforation for fracture is made in the panels at all four corners. It may be only partially pressed in. A notch may be used to provide the fracture point, in a variety of forms, and this may not be carried right through to the edge at full depth. There may be two perforations or notchings in two different widths at each corner.

Description

Sollbruchstelle bei AsbestzementplattenPredetermined breaking point in asbestos cement panels

Seit vielen Jahren werden Asbestzementplatten in flacher und gewellter Ausführung auf dem Markt angeboten. Die Plattenlänge ist variabel und reicht von 0g5 bis 3,5 m. ei den Wellasbestzementplatten wird die Standardbreite durch die Wellung bestimmt.For many years, asbestos-cement sheets have been used in flat and corrugated forms Execution offered on the market. The plate length is variable and ranges from 0g5 to 3.5 m. With corrugated asbestos cement panels, the standard width is determined by the Undulation determined.

Beim Eindecken mit Asbestzementplatten, vor allen Dingen in der gewellten Ausfiihrung, ist es unerläßlicji, daß die Platten an den Ecken gekappt werden, da sonst ein sauberes und dichtes Überdecken der Platten nicht möglich ist und eine vierfache Lage an diesen Stellen entstehen würde.When covering with asbestos-cement sheets, especially in the corrugated Execution, it is essential that the panels are capped at the corners otherwise a clean and tight covering of the plates is not possible and one fourfold position at these points would arise.

Bisher wurden die Wellasbestzementplatten auf der Baustelle mittels Winkelschleifer diagonal gekappt. Dieses Verfahren ist sehr aufwendig und vor allen Dingen mit einer enormen Staub entwicklung verbulldell .So far, the corrugated asbestos cement panels have been used on the construction site Angle grinder cut diagonally. This procedure is very complex and above all Things with an enormous amount of dust verbulldell.

Es sind auch Versuche unternommen worden die Ecken mittels Stanzvorrichtung diagonal zu kappen. Dieses Verfahren setzt eine hohe Lagerhaltung voraus.Attempts have also been made to punch the corners to cap diagonally. This process requires a high level of storage.

Die von mir entwickelten Asbestzementplatten können auf allen herkömmlichen Plattenherstellungsmaschinen ohne großen Aufwand gefertigt werden.The asbestos cement panels I have developed can be used on all conventional Plate making machines can be manufactured with little effort.

Es bieten sich verschiedene Möglichkeiten an: 1. Bei Typ 1 wird die Platte während der Fertigung im nassen Zustand an allen Ecken mit einer Perforierung - die ganz durchgestoßen ist (l) - versehen.There are various possibilities: 1. With type 1, the Plate with perforations at all corners during production when wet - which is completely pierced (l) - provided.

Es ist auch möglich, diese Perforierung nur teilweise einzudrücken (2), um ein Eindringen des Wassers auf dem Dach zu vermeiden. It is also possible to only partially impress this perforation (2) to prevent water from entering the roof.

2. Bei Typ 2 wird die Sollbruchstelle durch eine Kerbe (3) im Naßzustand erreicht. Die Kerbe kann verschiedene Ausführungen haben, z. B. a1 b oder c der Zeichnung. Die Kerbe (3) soll eine Tiefe von ca. 2/3 der Materialstärke haben, um ein einwandfreies Abbrechen der Plattenecken zu ermöglichen. Die Kerbung ist nicht in voller Tiefe bis zum Rand (4) der Platte vorgesehen, um ein Eindringen des Wassers auf dem Dach an der offenliegenden1 nicht ahgekappten Seite zu vermeiden.2. With type 2, the predetermined breaking point is indicated by a notch (3) when it is wet achieved. The notch can have various designs, e.g. B. a1 b or c the Drawing. The notch (3) should have a depth of approx. 2/3 the thickness of the material a perfect cancellation to enable the panel corners. the Notch is not provided in full depth to the edge (4) of the plate in order to make a Penetration of water on the roof on the exposed1 uncapped side to avoid.

Da beim Eindecken der Dächer mit Wellasbestzementplatten je nach Dachneigung mit zwei verschiedenen Überdeckungen gearbeitet wird kann die Perforierung oder Einkerbung der Asbestzementplatten in einem Arbeitsgang mit zwei verschiedenen Winkeln und Breiten (5) ausgeführt werden.As when covering the roofs with corrugated asbestos cement panels depending on the roof pitch Two different overlaps are used, the perforation or Notching the asbestos cement panels in one operation with two different angles and widths (5).

Das Kappen der perforierten bzw. eingekerbten Ecken kann auf der Baustelle mittels hammer und Itneifzange geschehen. Wird das Dach von links nach rechts gedeckt, wird die linke obere und rechte untere Ecke gekappt. Wird das Dach von rechts nach links gedeckt, wird die rechte obere und die linke untere Ecke gekappt.The perforated or notched corners can be capped at the construction site done with a hammer and pliers. If the roof is covered from left to right, the upper left and lower right corners are cut. Will the roof right to covered on the left, the upper right and lower left corners are cut.

Diese Methode ist denkbar einfach, erfordert bei den Ilerstellern und Verarbeitern keine erhöhte Lagerhaltung und ist in jedem Falle umweltfreundlich, weil die Staubentwicklung der herkömmlichen Verarbeitung wegfälltThis method is very simple, required by the manufacturers and processors no increased storage and is environmentally friendly in any case, because there is no dust generation from conventional processing
