Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung von Streckgitterelementen. Erfindungsgemäß wird die Aufgabe bei einem Verfahren zur Herstellung von Streckgitterelementen dadurch gelöst, dass der Vorschub des Materials, aus dem das Streckgitter hergestellt wird, entsprechend den statischen Eigenschaften des fertigen Streckgitterelements variiert wird.The invention relates to a method for producing expanded metal elements. According to the invention the object is achieved in a method for producing expanded metal mesh elements in that the feed of the material from which the expanded metal mesh is produced, is varied according to the static properties of the finished expanded metal mesh element.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Streckgitterelementen.The The invention relates to a process for the production of expanded metal elements.
Ein Streckgitter ist ein Werkstoff mit Öffnungen in der Fläche. Sie entstehen durch versetzte Schnitte ohne Materialverlust unter gleichzeitig streckender Verformung. Die Maschen des aus Tafeln oder Bändern gefertigten Materials sind weder geflochten noch geschweißt.One Expanded mesh is a material with openings in the surface. she caused by staggered cuts without loss of material at the same time stretching deformation. The stitches made from boards or ribbons Materials are neither braided nor welded.
Die Art eines Streckgitters wird durch die folgenden wesentliche Merkmale definiert: Maschenlänge, Maschenbreite, Maschenöffnung, Stegbreite, Stegdicke, Knotenpunkt, Knotenlänge, Knotenbreite und Steggitterdicke.The Type of expanded metal is characterized by the following essential features defined: mesh length, Mesh width, mesh size, Bridge width, web thickness, node, node length, node width and web grid thickness.
Stand der Technik ist die Herstellung eines Streckgitterelementes nach fest eingestellten Maßen. Das heißt, pro Element bleiben die oben vorgenannten Merkmale immer konstant, egal von der Rautenform oder dem gleich bleibenden Stegbreitenmuster der Masche, abgesehen von üblichen Toleranzen bei der Metallbearbeitung.was standing The technique is the production of an expanded metal element according to fixed dimensions. This means, per element, the abovementioned features always remain constant, regardless of the diamond shape or the consistent web width pattern the mesh, apart from usual Tolerances in metalworking.
Durch die Ausbildung von unterschiedlichen Stegbreiten bzw. Änderung des Stegbreitenmusters innerhalb eines Gitterelementes kann jedoch bei gleich bleibender Stegdicke (bestimmt durch die Blechdicke) die Formstabilität bzw. Durchdringungszeit dem Verwendungszweck angepasst werden.By the training of different web widths or change However, the web width pattern within a grid element may with constant web thickness (determined by the sheet thickness) the dimensional stability or breakthrough time are adapted to the intended use.
In Justizvollzugsanstalten werden Zäune bzw. Mauerkronen sowie Dachkantensicherungen mit Streckmetallbeplankungen errichtet, welche folgenden Ansprüchen genügen müssen. Im Standbereich einer Person (bis ca. 2,0–3,0 m Oberkante Gelände) sollte die Streckgitter-Beplankung einen hohen Widerstand gegen Krafteinwirkung aufweisen und in sich sehr formstabil sein, um ein Durchdringen mit Werkzeugen bzw. durch Gewaltanwendung zu minimieren.In Prisons will be fences or Masonry crowns and roof edge fences with expanded metal skins built, which must meet the following requirements. In the stand area of a Person (up to approx. 2.0-3.0 m top edge terrain) The expanded metal planking should have a high resistance against Have force and in itself very dimensionally stable to a Penetration with tools or by using force to minimize.
Dagegen wird im Zaunkronenbereich (ca. 3,0–5,0 m) Instabilität des Streckgitterelementes (flexibel) erwünscht, um ein Überwinden durch eine Person zu behindern. Zusätzlich sollen Klirrfaktoren, entstehend durch das Verbinden mehrerer Bauteile, verringert werden.On the other hand becomes in the fence area (about 3.0-5.0 m) instability of the expanded metal mesh element (flexible) desired, to overcome hampered by a person. In addition, distortion factors, incurred by connecting a plurality of components can be reduced.
Bisher wurden diese Eigenschaften nur durch die Kombination unterschiedlich stabiler Elemente durch Zusammenfügen, z.B. durch Schweißen, erreicht.So far These properties were different only by the combination stable elements by joining, e.g. by welding, achieved.
Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit anzugeben, die die Nachteile des Standes der Technik beseitigt.Of the Invention has for its object to provide a way that the Disadvantages of the prior art eliminated.
Erfindungsgemäß wird die Aufgabe bei einem Verfahren zur Herstellung von Streckgitterelementen dadurch gelöst, dass der Vorschub des Materials, aus dem das Streckgitter hergestellt wird, entsprechend den statischen Eigenschaften des fertigen Streckgitters variiert wird.According to the invention Task in a process for the production of expanded metal elements solved by that the feed of the material from which made the expanded metal mesh is, according to the static properties of the finished expanded metal is varied.
Der Vorteil der Erfindung besteht in dem wesentlich besseren optischen Erscheinungsbild, der Einsparung von Verbindungselementen und Klirrfaktoren, der Erhöhung der Gebrauchseigenschaften variierbar nach den Ansprüchen des Nutzers, einem geringeren Verbrauch des Ausgangswerkstoffs und einer wesentlichen Einsparung von Montagezeit sowie der Einsparung von Materialkosten.Of the Advantage of the invention consists in the much better optical Appearance, the saving of fasteners and distortion factors, the increase the use characteristics variable according to the claims of User, a lower consumption of the starting material and a Significant saving of assembly time as well as the saving of Material costs.
Nachfolgend soll die Erfindung anhand von Zeichnungen näher erläutert werden. In den Zeichnungen zeigen:following the invention will be explained in more detail with reference to drawings. In the drawings demonstrate:
