The reinforcement grid can be rolled up and out. It has at least two rows of ribs between longitudinal strips, whereby the ribs of adjoining rows run in the dame direction. <IMAGE>

Description

Die Erfindung betrifft ein Armierungsgitter gemäss Oberbegriff des Anspruches 1 sowie eine Anlage zu dessen Herstellung gemäss Oberbegriff des Anspruches 9.The invention relates to a reinforcing mesh according to the preamble of claim 1 and a system for its production according to the preamble of claim 9.

Armierungsgitter der eingangs genannten Art sind bekannt, so beispielsweise aus der DE-OS 2 402 653. Diese Armierungsgitter bestehen aus in Längsrichtung verlaufenden Drähten, die mit quer dazu verlaufenden Drähten durch Schweissen verbunden sind. Nach dem Verschweissen kann das Armierungsgitter mittels einer Walzmaschine abgeflacht werden. Ein solches Armierungsgitter ist in der Herstellung sehr aufwendig und damit teuer. Überdies ist ein solches Armierungsgitter steif, so dass es nur in geraden Bahnen bestimmter Länge hergestellt, transportiert und verarbeitet werden kann.Reinforcing gratings of the type mentioned at the outset are known, for example from DE-OS 2 402 653. These reinforcing gratings consist of wires running in the longitudinal direction, which are connected to wires running transversely thereto by welding. After welding, the reinforcement grid can be flattened using a rolling machine. Such a reinforcement grid is very complex to manufacture and therefore expensive. In addition, such a reinforcement grid is stiff, so that it can only be manufactured, transported and processed in straight lengths of a certain length.

Aufgabe der Erfindung ist es, ein Armierungsgitter der eingangs genannten Art weiterzuverbessern und eine Anlage zur Herstellung des Armierungsgitters anzugeben.The object of the invention is to further improve a reinforcement grid of the type mentioned at the outset and to provide a system for producing the reinforcement grid.

Die Aufgabe wird gelöst durch:

  • a) das Armierungsgitter gemäss Anspruch 1; und
  • b) die Anlage gemäss Anspruch 9.
The task is solved by:
  • a) the reinforcement grid according to claim 1; and
  • b) the system according to claim 9.

Dadurch, dass das Armierungsgitter aus einem Blechband hergestellt wird und zwar durch Anbringen von Schrägschnitten oder -schlitzen und Verstrecken der zwischen den Schnitten oder Schlitzen gebildeten Stege, ergibt sich eine wesentliche Vereinfachung der Herstellung ohne Schweissen und damit ohne die mit dem Schweissen verbundene Gefahr der nachteiligen Gefügeänderung. Überdies sind Blechbänder als Ausgangsmaterial leicht beschaffbar. Da das Armierungsgitter bereits aus Blech besteht, ist ein Walzen in der Regel nicht erforderlich und vielfach sogar unerwünscht. Durch das Querverstrecken verdrehen sich die Stege zwischen den Längsstreifen quer zu der durch die Längsstreifen gegebenen Ebene, wodurch die Verzahnungseigenschaften des Armierungsgitters in der Mauerwerkfuge verbessert werden.The fact that the reinforcing mesh is produced from a sheet metal strip, namely by making bevel cuts or slits and stretching the webs formed between the cuts or slits, results in a significant simplification of production without welding and thus without the risk of disadvantageous associated with welding Structural change. In addition, sheet metal strips are easily procured as the starting material. Since the reinforcement grid is already made of sheet metal, rolling is generally not necessary and is in many cases even undesirable. As a result of the transverse stretching, the webs between the longitudinal strips twist transversely to the plane given by the longitudinal strips, as a result of which the toothing properties of the reinforcing mesh in the masonry joint are improved.

Die Anlage ermöglicht eine besonders einfache und wirtschaftliche Herstellung des Armierungsgitters, denn mit der speziellen Streckstation können die mit Schrägschnitten und -schlitzen versehenen Bänder besonders einfach und schnell kontinuierlich gestreckt werden.The system enables a particularly simple and economical production of the reinforcement grid, because with the special stretching station the tapes provided with bevel cuts and slots can be continuously and particularly easily and quickly stretched.

Besonders vorteilhafte Ausführungsbeispiele des Armierungsgitters sind in den Ansprüchen 2 bis 8 und der Anlage in den Ansprüchen 10 bis 13 beschrieben.Particularly advantageous exemplary embodiments of the reinforcement grid are described in claims 2 to 8 and the system in claims 10 to 13.

Zweckmässig ist eine Ausgestaltung nach Anspruch 2, da die Höhe der Stege die Dicke der herzustellenden Mauerwerkfuge bestimmen können.An embodiment according to claim 2 is expedient since the height of the webs can determine the thickness of the masonry joint to be produced.

Je nach den gewünschten Festigkeitseigenschaften des Armierungsgitters können die Dimensionen beliebig festgelegt werden, angefangen von der Dicke des Blechbandes, die beispielsweise nach Anspruch 3 2 und mehr mm betragen kann, und der Wahl der Breite der Längsstreifen und der Stege.Depending on the desired strength properties of the reinforcement grid, the dimensions can be set as desired, starting with the thickness of the sheet metal strip, which can be 2 mm or more, for example, according to claim 3, and the choice of the width of the longitudinal strips and the webs.

Das Armierungsgitter kann gegebenenfalls gemäss Anspruch 4 aufrollbar sein. Es lässt sich dann in grösseren Längen herstellen, aufrollen und im aufgerollten Zustand transportieren und lagern. Auf der Baustelle ist es dann lediglich erforderlich, das Armierungsgitter von der Rolle abzuwickeln und in gewünschter Länge abzuschneiden. Dadurch wird der Transport und die Lagerhaltung sowie die Handhabung des Armierungsgitters wesentlich vereinfacht.The reinforcing grid can optionally be rolled up according to claim 4. It can then be produced in greater lengths, rolled up and transported and stored in the rolled-up state. At the construction site it is then only necessary to unwind the reinforcement grid from the roll and cut it to the desired length. This considerably simplifies the transport and storage as well as the handling of the reinforcement grid.

Falls ein besonders stabiles Armierungsgitter gewünscht wird oder dieses eine besonders grosse Breite aufweisen soll, ist eine Ausgestaltung nach einem der Ansprüche 5 bis 7 von Vorteil.If a particularly stable reinforcement grid is desired or if it is to have a particularly large width, an embodiment according to one of claims 5 to 7 is advantageous.

Gegebenenfalls kann es zweckmässig sein, das Armierungsgitter mit einer Profilierung, vorzugsweise Wellung zu versehen, um die Verankerung des Armierungsgitters im Mauerwerk zu verbessern.If necessary, it may be appropriate to provide the reinforcement mesh with a profile, preferably corrugation, in order to improve the anchoring of the reinforcement mesh in the masonry.

Die Streckräder der Streckstation können gemäss Anspruch 10 mit einem eigenen Antrieb versehen sein. Vorteilhafter ist jedoch eine Ausbildung nach Anspruch 11.The stretching wheels of the stretching station can be provided with their own drive according to claim 10. However, an embodiment according to claim 11 is more advantageous.

Zweckmässigerweise wird das aus der Streckstation kommende Armierungsgitter in einer Glättvorrichtung nach Anspruch 12 wenigstens bis zu einem bestimmten Grad geglättet und kann dann gegebenenfalls mit der Anlage nach Anspruch 13 profiliert werden.Appropriately, the reinforcement grid coming from the stretching station is smoothed at least to a certain degree in a smoothing device according to claim 12 and can then optionally be profiled with the system according to claim 13.

Die Figur 1 zeigt ein Blechband 2 der Breite c mit schräg zur Längsrichtung verlaufenden Schnitten oder Schlitzen 4, die zwischen sich Stege 6 bilden. Die beiden Enden der Stege bleiben mit den Längsstreifen 8,10 verbunden. Durch seitliches Verstrecken des Blechbandes 2 auf den Abstand a der Längsstreifen werden die Stege 6 etwa senkrecht zur Längsrichtung des Blechbandes ausgerichtet und dabei verdreht, wie aus den Figuren 2 und 3 hervorgeht. Die Breite b der Stege im Blechband 2 bestimmen später die Höhe h der aufgestellten Stege 6. Dabei können die Breite b beziehungsweise die Höhe h so eingestellt werden, dass sie der Dicke der herzustellenden Mauerwerkfuge entsprechen. Die aufgestellten Stege, die beispielsweise beidseits der Ebenen der Längsstreifen 8,10 vorstehen können, verbessern die Verankerung des Armierungsgitters in der Mörtelschicht der Mauerwerkfuge.FIG. 1 shows a sheet metal strip 2 of width c with cuts or slits 4 which run obliquely to the longitudinal direction and form webs 6 between them. The two ends of the webs remain connected to the longitudinal strips 8, 10. By lateral stretching of the sheet metal strip 2 to the distance a of the longitudinal strips, the webs 6 are aligned approximately perpendicular to the longitudinal direction of the sheet metal strip and thereby rotated, as can be seen from FIGS. 2 and 3. The width b of the webs in the sheet metal strip 2 later determine the height h of the webs 6 that are set up. The width b or the height h can be set such that they correspond to the thickness of the masonry joint to be produced. The raised webs, which can protrude, for example, on both sides of the levels of the longitudinal strips 8, 10, improve the anchoring of the reinforcement grid in the mortar layer of the masonry joint.

Das für die Herstellung des Armierungsgitters notwendige Blechband kann eine Dicke d von 2 und mehr mm aufweisen und aus einem nicht rostenden Stahl, wie beispielsweise einem Inox-Stahl bestehen.The sheet metal strip necessary for the production of the reinforcement grid can have a thickness d of 2 or more mm and consist of a stainless steel, such as an inox steel.

Die Figuren 4 und 5 zeigen ein weiteres Armierungsgitter, das zwischen drei Längsstreifen 12,14,16 jeweils eine Reihe 18,20 aus Stegen 22,24 aufweist. In Figur 4 sind die Stege 22,24 gleichgerichtet, während die Stege 22a,24a der Figur 5 entgegengesetzt gerichtet sind. Die Stege der einzelnen Reihen können auch in nicht näher dargestellter Weise zueinander versetzt angeordnet werden.FIGS. 4 and 5 show a further reinforcement grid, each of which has a row 18, 20 of webs 22, 24 between three longitudinal strips 12, 14, 16. In FIG. 4, the webs 22, 24 are oriented in the same direction, while the webs 22a, 24a in FIG. 5 are directed in the opposite direction. The webs of the individual rows can also be arranged offset from one another in a manner not shown.

Die Herstellung des Armierungsgitters ist ausserordentlich einfach, da das Blechband fortlaufend in aufeinanderfolgenden Arbeitsschritten einerseits mit den schräg gestellten Schnitten oder Schlitzen versehen und andererseits seitlich verstreckt werden kann. Gegebenenfalls kann das Armierungsgitter nach dem Verstrecken geglättet und/oder mit quer zur Längsrichtung verlaufenden Profilierungen, beispielsweise Wellungen, versehen werden. Anschliessend kann das fertige Armierungsgitter gegebenenfalls aufgerollt werden. In Rollenform kann das Armierungsband gelagert und transportiert werden. Am Verwendungsort ist es dann lediglich erforderlich, die notwendige Länge an Armierungsgitter von der Rolle abzuwickeln und abzuschneiden und auf der Mauerwerkfuge zu verlegen. Insbesondere dann, wenn das Armierungsgitter in Längsrichtung und/oder in Querrichtung profiliert ist, ist es vorteilhaft, das Armierungsgitter unmittelbar nach der Herstellung auf Abschnitte gewünschter Länge abzulängen und die Abschnitte zu einem lager- und transportfähigen Bündel zusammenzufassen.The production of the reinforcement grid is extremely simple, since the sheet metal strip can be provided with the inclined cuts or slots on the one hand in successive working steps and on the other hand can be stretched laterally. If necessary, the reinforcement grid can be smoothed after stretching and / or with transverse to the longitudinal direction extending profiles, such as corrugations. The finished reinforcing mesh can then be rolled up if necessary. The reinforcement tape can be stored and transported in roll form. At the place of use, it is then only necessary to unwind and cut the necessary length of reinforcing mesh from the roll and to lay it on the masonry joint. Particularly when the reinforcement grid is profiled in the longitudinal direction and / or in the transverse direction, it is advantageous to cut the reinforcement grid to sections of the desired length immediately after manufacture and to combine the sections into a bundle that can be stored and transported.

Die Figuren 6 bis 8 zeigen eine besonders bevorzugte Anlage zur Herstellung solcher Armierungsgitter. Von einer Vorratsrolle 26 wird ein Blechband 2 abgezogen und einer Schneidstation 28 zugeführt, die zwei gegeneinander wirkende Schneidrollen 30 aufweist, von denen nur eine gezeigt ist, und die mittels eines Antriebes 32 angetrieben werden. Die Schneidrollen 30 haben eine bekannte Ausbildung und weisen Schneidkanten 34 auf, die zur Herstellung der Schnitte oder Schlitze 4 dienen, aus denen die Stege 6 gebildet werden. Das so geschnittene Blechband wird über Umlenkrolen 36,38 gewendet und einer Streckstation 40 zugeführt, die mit Streckrädern 42,44 ausgestattet ist und die anhand der Figur 7 nachfolgend noch näher beschrieben sind. Der Streckstation folgt eine Glättvorrichtung 46, welche beispielsweise zwei gegeneinander wirkende glatte Walzen 48 aufweisen kann, und die das aus der Streckstation 40 kommende, im Querschnitt Z-förmige Armierungsgitter mehr oder weniger flach presst. In einer nachfolgenden Profiliervorrichtung 50, welche gemäss Figur 8 zwei gegeneinander wirkende Zahnräder 52,54 aufweist, kann das Armierungsgitter wieder mit quer zur Laufrichtung angeordneten Profilierungen 56 zum Beispiel in Form von Wellen versehen werden, um die Haft- beziehungsweise Verkrallungseigenschaften des Armierungsgitters bei der späteren Verwendung im Mauerwerk zu verbessern. Der Profiliervorrichtung 50 folgt eine Abzugsvorrichtung 58, die mit einem Antrieb 60 ausgestattet ist, um das Armierungsgitter von der Schneidstation 28 durch die Anlage zu ziehen. Die separate Abzugsvorrichtung 58 kann auch entfallen, wenn die Glättvorrichtung 46 und/oder die Profiliervorrichtung 50 mit einem Antrieb versehen sind, sodass sie die Abzugsfunktion übernehmen können. Das hergestellte Armierungsgitter wird in gewünschten Längen abgeschnitten und die Armierungsgitterabschnitte 62 zu einem transport- und lagerfähigen Bündel 64 zusammengefasst.Figures 6 to 8 show a particularly preferred system for producing such reinforcing mesh. A sheet metal strip 2 is drawn off from a supply roll 26 and fed to a cutting station 28 which has two counter-acting cutting rolls 30, only one of which is shown, and which are driven by a drive 32. The cutting rollers 30 have a known design and have cutting edges 34 which are used to produce the cuts or slots 4 from which the webs 6 are formed. The sheet metal strip cut in this way is turned over deflection rollers 36, 38 and fed to a stretching station 40, which is equipped with stretching wheels 42, 44 and which are described in more detail below with reference to FIG. 7. The stretching station is followed by a smoothing device 46, which can have, for example, two counteracting smooth rollers 48 and which presses the reinforcing grid coming from the stretching station 40, which is Z-shaped in cross section, more or less flat. In a subsequent profiling device 50, which, according to FIG. 8, has two gear wheels 52, 54 acting against one another, the reinforcement grid can again be provided with profiles 56 arranged transversely to the running direction, for example in the form of waves, in order to improve the adhesive or claw properties to improve the reinforcement grid for later use in masonry. The profiling device 50 is followed by a pull-off device 58, which is equipped with a drive 60 in order to pull the reinforcement grid from the cutting station 28 through the system. The separate extraction device 58 can also be omitted if the smoothing device 46 and / or the profiling device 50 are provided with a drive, so that they can take over the extraction function. The reinforcing mesh produced is cut to the desired lengths and the reinforcing mesh sections 62 are combined to form a bundle 64 that can be transported and stored.

Das besondere Kernstück der Anlage bildet die Streckstation 40 mit den Streckrädern 42,44, wie dies in Figur 7 dargestellt ist. Die Streckräder weisen unterschiedliche Durchmesser D1 und D2 auf und sind an zwei derart versetzten Achsen 66,68 angeordnet, dass die Stirnseiten 70,72 der Streckräder 42,44 an der Einlaufseite 74 gleiche Mantellinien aufweisen. Die Streckräder 42,44 weisen einen axialen Abstand C auf, der grösser ist als die Dicke d des zu bearbeitenden Blechbandes 2. Die Durchmesserdifferenz D1 minus D2 der beiden Streckräder 42,44 entspricht im wesentlichen dem Abstand a der äusseren Längsstreifen 8,10,12 und 16 der Armierungsgitter der Figuren 2, 4 und 5. Die Streckräder sind von der Einlaufseite 74 ausgehend mit einem Gehäuse 76 umgeben, das Stirnseitenführungen 78,80 bildet, die bis zur Auslaufseite 82 reichen. Der radiale Abstand A der Stirnseiten 70,72 der Streckräder 42,44 von den zugehörigen Stirnseitenführungen 78,80 ist geringfügig grösser als die Dicke d des zu verarbeitenden Blechbandes 2. Die Breite B des Spaltes zwischen den Stirnflächen 84,86 und den Stirnführungen 78,80 entspricht der Breite c des zu bearbeitenden Blechbandes. Wie sich nun aus Figur 7 ergibt, läuft das zu bearbeitende Blechband an der Einlaufseite 74 in die Streckvorrichtung ein und wird durch die versetzt angeordneten Streckräder 42,44 und deren unterschiedliche Durchmesser D1,D2 gestreckt, wobei die Längsstreifen 8,10 in den Spalten zwischen den Stirnflächen 84,86 und den zugehörigen Stirnseitenführungen 78,80 verbleiben und soweit voneinander gestreckt werden, dass der Steg 6 in dem Spalt zwischen den Streckrädern 42,44 auf den Abstand a verstreckt wird. An der Auslaufseite 82 weist das Armierungsgitter eine Z-förmige Form auf und wird deshalb zweckmässigerweise in der Glättvorrichtung 46 soweit geglättet, dass es die in den Figuren 2 bis 5 gezeigte Form einnimmt.The special core of the system is the stretching station 40 with the stretching wheels 42, 44, as shown in FIG. The stretching wheels have different diameters D1 and D2 and are arranged on two axially displaced axles 66, 68 such that the end faces 70, 72 of the stretching wheels 42, 44 on the inlet side 74 have the same surface lines. The stretching wheels 42, 44 have an axial distance C which is greater than the thickness d of the sheet metal strip 2 to be processed. The diameter difference D1 minus D2 of the two stretching wheels 42, 44 essentially corresponds to the distance a of the outer longitudinal strips 8, 10, 12 and 16 the reinforcing mesh of FIGS. 2, 4 and 5. Starting from the inlet side 74, the stretching wheels are surrounded by a housing 76 which forms end-side guides 78, 80 which extend to the outlet side 82. The radial distance A of the end faces 70, 72 of the stretching wheels 42, 44 from the associated end face guides 78, 80 is slightly larger than the thickness d of the sheet metal strip 2 to be processed. The width B of the gap between the end faces 84, 86 and the end guides 78, 80 corresponds to the width c of the sheet metal strip to be processed. As can now be seen from FIG. 7, the sheet metal strip to be processed runs into the stretching device on the inlet side 74 and is displaced by the staggered stretching wheels 42, 44 and their different ones Diameter D1, D2 stretched, the longitudinal strips 8, 10 remaining in the gaps between the end faces 84, 86 and the associated end face guides 78, 80 and being stretched from one another to such an extent that the web 6 in the gap between the stretching wheels 42, 44 on the Distance a is stretched. At the outlet side 82, the reinforcement grid has a Z-shaped shape and is therefore expediently smoothed in the smoothing device 46 to such an extent that it assumes the shape shown in FIGS. 2 to 5.

Mittels der gezeigten Anlage können Armierungsgitter derart präzise und schnell, beispielsweise mit der Geschwindigkeit von einem Meter pro Sekunde, hergestellt werden, dass jeder Auftrag individuell sofort bearbeitet werden kann und eine Lagerhaltung vorfabrizierter Armierungsgitter überflüssig wird.Using the system shown, reinforcement grids can be produced so precisely and quickly, for example at a speed of one meter per second, that each order can be processed immediately and individually, and storage of prefabricated reinforcement grids becomes superfluous.
