Definitions
- the invention relates to a fence and a method for assembling fences by reshaping a fence connector.
- An increasingly integral part of modern fence systems are steel mesh mats, consisting of crosswise arranged horizontal and vertical bars that are welded to each other at the cross points, which are endlessly strung together and fastened to posts to form a fence system.
- the mats can be galvanized or additionally coated with plastic and have different mesh sizes depending on the application.
- the steel mesh mats are easy to manufacture and, in principle, also easy to assemble into fencing systems.
- a clamp connection is also known from practice, in which, with the vertical rods being recessed, one engages in a form-fitting manner against the abutting steel mesh mats lying at the same height after they have been deformed by a clamp.
- the metal double brackets connected by screws also have disadvantages.
- an exact alignment of the fence is necessary, in particular an exact distance between the vertical bars to be connected, since these metal plates are preformed and the fence connector is only held when both the tab and the vertical bars are aligned accordingly.
- the screw also allows certain frictional forces as holding forces and the connection is also easy to screw apart. For the rest, the trend is towards ever lighter, at least more graceful looking fences with equally sized horizontal and vertical bars, where a clunky mat connection would be disruptive.
- pliers for pressing a cross connector with ends are U-shaped Cross section for orthogonally aligned individual rods, which together form a cross point, described.
- the pliers levers are connected to each other in a first joint and each have a second joint, on which spreading levers are pivotally mounted on the one hand.
- the spreading levers At their other ends, the spreading levers have jaws which, in the closed state, have an O-shaped opening - corresponding to the circular circumference of one end of the cross connector - and can be pivoted about a joint of the two spreading levers located below the jaws. When open, the jaws also gap widely on their underside.
- the cross connector can only be held in the jaws in the desired position during the clamping process, because in the middle of the jaw, transversely to the jaw opening, there is a groove that extends over the entire jaw depth and in which the ends of the cross connector, which are not to be formed in the current clamping process, rest. Without this adjustment groove for the specially shaped cross connector, the pliers would be very difficult to handle.
- an H-shaped sheet metal body is known from GB-A-1 132 732, with which adjacent vertical bars of two lattice mats can be connected at a distance from one another.
- Lattice mats for example also of fences, are to be connected at right angles to their edge meshes by simultaneously bending the edge parts of the sheet metal body above and below horizontal bars around the vertical bars.
- the invention is therefore based on the problem of proposing a barely perceptible mat connection for fences, which is independent of the grid dimension in which the fence posts are arranged, can be installed as easily as possible and is secured against unintentional loosening.
- Another object of the invention is to propose a simple fence assembly method for this mat connection using a suitable tool.
- Such sheet metal clamps for fence mat connection can be arranged directly above and immediately below two offset horizontal bars on the vertical bars. This prevents the steel mesh mats from moving vertically against each other.
- the solution for the fence connection is even more elegant if the steel mesh mats have, for reasons of stability, beads running in the horizontal direction in at least one or more meshes of the steel mesh mat. Then one of these sheet metal clamps can be arranged in the area of the bead, while the second is arranged on the vertically running part of the steel grid mat. This results in a secure connection of adjacent vertical bars in two axes of the steel mesh mat, so that they lie immovably next to each other.
- connection should be made outside the area of a fence post, as there is enough space there to attach a tool for the assembly of the fence connector.
- mat can be easily preassembled on a horizontal or vertical bar with the post if the connection between two steel mesh mats is not in front of the post and the distance between the fence posts and their foundations from one another need not be determined to the centimeter before the fence assembly.
- Another anti-slip device against the vertical displacement of two steel mesh mats results if the vertical rods to be connected are provided with a plastic coating, because then the coefficient of friction between rod and connector is significantly higher.
- a fence connector that can be used for the fence according to the invention consists of a C-shaped sheet metal part, the dimensions of which are determined essentially by the thickness of the bars to be connected and the sheet thickness, the length of the fence connector should be more than twice the thickness of the vertical bar, so that an accurate angle Forming the fence connector is possible and this is not twisted during the forming.
- stainless steel is preferred as the material for such a fence connector.
- each jaw of the lever pliers is mounted several times in the jaw joint arranged directly below the abutment, so that the jaws cannot rotate relative to the joint.
- a fence post 10 is shown on which a steel mesh mat is attached by means of holder 11.
- the steel mesh mat ends in the closed edge mesh 3 with the vertical rod 7.
- a further steel mesh mat consisting of mesh-forming, crosswise arranged, welded together at the crossing points horizontal rods 1, 4, 5 and vertical rods 2, 6, which are in turn closed, is to be attached to this edge mesh
- Have edge stitches 3 The two vertical bars 6, 7 are enclosed and securely held by two fence connectors 8, 9 designed as sheet metal clamps.
- the connector 9 rests directly below the horizontal bar 1, the connector 8 immediately above the horizontal bar 5, so that a displacement of the two edge meshes 3 in the vertical direction becomes impossible.
- Figure 2 shows in vertical section through a connection point of two steel mesh mats a vertical rod 12 with horizontal rods 13, the vertical rod 12 being bent so that a bead 14 is formed.
- This bead 14 is used to arrange a connector 30 in the area of this bead, while a second connector 31 is arranged in the vertical part of the steel mesh mat outside of the bead 14. This results in a two-axis securing of the steel mesh mats against vertical displacement. A horizontal displacement is not possible anyway when the connectors 30, 31 are arranged around the vertical rods 12.
- Figure 3 shows the head of a lever pliers, consisting of the levers 24, 25 which are connected to each other on the lever heads 26, 27 by the joint 23.
- expansion joints 21, 22 expansion levers 19, 20 are pivotally mounted.
- the actual tool jaws 15, 16 are attached to the ends of the spreading levers 19, 20, for example by soldering. These jaws 15, 16 are in turn connected by their overlapping lower ends 28, 29, which form a support for the base of the sheet metal clamp 9, by a jaw joint 18.
- Each jaw 15, 16 is supported at least twice in the jaw joint 18 in order to prevent the jaws from twisting against one another. The jaws are drawn in the open state.
- a fence connector 9 was inserted with the position shown, which was held there with the jaws slightly pretensioned and pushed around the vertical bars 6, 7 analogously to the illustration in FIG. After the position of the fence connector 9 shown is reached, can the jaws 15, 16 are pressed together using the levers 24, 25 so that the legs of the fence connector 9 close around the vertical rods 6, 7.

Abstract
Description
Die Erfindung betrifft einen Zaun und ein Verfahren zur Montage von Zäunen durch Umformen eines Zaunverbinders.The invention relates to a fence and a method for assembling fences by reshaping a fence connector.
Integraler Bestandteil moderner Zaunanlagen sind immer häufiger Stahlgittermatten, bestehend aus kreuzweise angeordneten, miteinander an den Kreuzpunkten verschweißten Horizontal- und Vertikalstäben, die endlos aneinandergereiht und an Pfosten befestigt, eine Zaunanlage bilden. Die Matten können verzinkt oder zusätzlich auch mit Kunststoff beschichtet sein und weisen anwendungsspezifisch unterschiedliche Maschengröße auf. Die Stahlgittermatten sind problemlos herstellbar und im Prinzip auch einfach zu Zaunanlagen montierbar.An increasingly integral part of modern fence systems are steel mesh mats, consisting of crosswise arranged horizontal and vertical bars that are welded to each other at the cross points, which are endlessly strung together and fastened to posts to form a fence system. The mats can be galvanized or additionally coated with plastic and have different mesh sizes depending on the application. The steel mesh mats are easy to manufacture and, in principle, also easy to assemble into fencing systems.
Das größte Problem für einen optisch ansprechenden Zaun bilden die Mattenverbinder an den Stoßstellen zwischen zwei Stahlgittermatten.The biggest problem for a visually appealing fence are the mat connectors at the joints between two steel mesh mats.
Es sind drei prinzipielle Arten von Verbindern für Stahlgittermatten bekannt. Sehr häufig werden die Stahlgittermatten vor Zaunpfählen, die im Boden verankert sind, aneinandergestoßen und dort am Zaunpfahl fixiert. Diese Fixierung erfolgt durch eingeklemmte Deckleisten oder spezielle Laschen, die an den Zaunpfosten geschraubt werden; entsprechende Beispiele sind in den DE-Offenlegungsschriften 19 06 391, 24 19 636, 30 29 712, 29 03 774, 38 24 721 beschrieben.Three basic types of connectors for steel mesh mats are known. The steel mesh mats are very often pushed together in front of fence posts that are anchored in the ground and fixed there on the fence post. This fixation is done by clamped cover strips or special tabs that are screwed to the fence post; corresponding examples are described in DE laid-
Eine grazilere Form haben spezielle aus den Drahtgittern selbst geformte Pfosten, die auf kurzen Stützen ruhen. Derartige integrale Zaunpfähle bedürfen aber ebenso wie die Verbinder gemäß den DE-Offenlegungsschriften 24 12 381, 26 45 905, 25 34 767 spezieller Klemmlaschen, die zwei jeweils benachbarte Vertikalstäbe von vorn und hinten umschließen und durch eine zentrale Schraube miteinander verbunden sind.A more graceful shape have special posts formed from the wire grids themselves, which rest on short supports. Such integral fence posts, however, just like the connectors according to DE laid-
Aus der Praxis ist weiterhin eine Klemmverbindung bekannt, bei der unter Aussparung der Vertikalstäbe eine die Horizontalstäbe auf gleicher Höhe liegender, aneinanderstoßender Stahlgittermatten formschlüssig umgreifen, nachdem sie durch eine Klemmzange umgeformt wurden.A clamp connection is also known from practice, in which, with the vertical rods being recessed, one engages in a form-fitting manner against the abutting steel mesh mats lying at the same height after they have been deformed by a clamp.
Alle diese Systeme haben einen Nachteil. Soweit Zaunpfosten verwendet werden, bedarf es einer äußerst exakten Vermessung und Positionierung der Zaunpfosten, damit die Gittermatten mit ihren vorgefertigten Längen genau vor den Zaunpfosten enden, um dort miteinander verbunden zu werden. Dies bedeutet einen sehr hohen Montageaufwand, weil die Pfosten unabhängig vom Gelände äußerst exakt zu setzen sind. In vielen Fällen lassen sich aber diese Zaunpfosten-Abstände nicht einhalten, wenn zum Beispiel steiniger Boden oder ähnliches als Hindernis auftritt.
Der Verbinder von Horizontalstäben kann sich aufgrund Eigenlast der Matten und weiterer ungewollter Belastung, zum Beispiel durch eine den Zaun übersteigende Person, verbiegen. Aus diesem Grunde wird diese Verbindung nur bei Matten mit horizontalen Doppelstäben oder verstärkten Horizontalprofilen angewendet.All of these systems have a disadvantage. As far as fence posts are used, the fence posts need to be measured and positioned extremely precisely, so that the lattice mats with their prefabricated lengths end exactly in front of the fence posts in order to be connected to one another there. This means a very high assembly effort, because the posts can be set extremely precisely regardless of the terrain. In many cases, however, these fence post distances cannot be maintained if, for example, stony ground or the like occurs as an obstacle.
The connector of horizontal bars can bend due to the mat's own load and other unwanted loads, for example by a person crossing the fence. For this reason, this connection is only used for mats with horizontal double bars or reinforced horizontal profiles.
Auch die durch Schrauben verbundenen metallenen Doppellaschen haben Nachteile. Zum einen ist eine genaue Ausrichtung des Zaunes erforderlich, insbesondere ein exakter Abstand der zu verbindenden Vertikalstäbe zueinander, da diese Metallplättchen vorgeformt sind und ein Halt des Zaunverbinders sich nur dann ergibt, wenn sowohl die Lasche als auch die Vertikalstäbe entsprechend ausgerichtet sind. Die Schraube läßt zudem bestimmte Reibkräfte als Haltekräfte zu und die Verbindung ist zudem leicht auseinander zu schrauben.
Im übrigen geht der Trend zu immer leichteren, zumindestens graziler aussehenden Zäunen mit gleich dimensionierten Horizontal- und Vertikalstäben, bei denen eine klobige Mattenverbindung störend wirken wiirde.The metal double brackets connected by screws also have disadvantages. On the one hand, an exact alignment of the fence is necessary, in particular an exact distance between the vertical bars to be connected, since these metal plates are preformed and the fence connector is only held when both the tab and the vertical bars are aligned accordingly. The screw also allows certain frictional forces as holding forces and the connection is also easy to screw apart.
For the rest, the trend is towards ever lighter, at least more graceful looking fences with equally sized horizontal and vertical bars, where a clunky mat connection would be disruptive.
Aus der DE-U-19 84 294 sind für aus zick-zack-förmig gebogenen, in den Knickpunkten aneinanderstoßenden, Profilen zusammengesetzte Zäune mit U-förmigen Verbindern für die Stoßstellen der Profile bekannt, die nach O-förmiger Verformung ein Innenprofil haben, das genau der Umhüllenden der beiden zu verbindenden Profile entspricht. Verbinder für Vertikalstäbe von Stahlgittermatten oder eine Bemessungsregel für derartige Verbinder sind nicht offenbart.From DE-U-19 84 294 for zig-zag-shaped, in the hitting points abutting profiles assembled fences with U-shaped connectors for the joints of the profiles are known, which have an inner profile after O-shaped deformation, the corresponds exactly to the envelope of the two profiles to be connected. Connectors for vertical bars of steel mesh mats or a design rule for such connectors are not disclosed.
Aus einem "elkosta-Prospekt" 8.80/25-A-Do sind Runddrahtklammern aus Edelstahl zum Umringen von Maschendrähten mit Hilfe einer speziellen Drahtklammerzange bekannt.From an "elkosta brochure" 8.80 / 25-A-Do, round wire clips made of stainless steel for wrapping wire mesh using a special wire clip pliers are known.
Schließlich ist in der FR-PS 774948 eine Zange zum Zusammendrücken eines Kreuzverbinders mit Enden u-förmigen Querschnittes für orthogonal zueinander ausgerichtete einzelne Stäbe, die gemeinsam einen Kreuzpunkt bilden, beschrieben. Die Zangenhebel sind in einem ersten Gelenk miteinander verbunden und weisen je ein zweites Gelenk auf, an denen Spreizhebel einerseits schwenkbar gelagert sind. Die Spreizhebel weisen an ihren anderen Enden Backen auf, die im Schließzustand eine O-förmige Öffnung - entsprechend dem kreisförmigen Umfang eines Endes des Kreuzverbinders - aufweisen und um ein unterhalb der Backen gelegenes gemeinsames Gelenk beider Spreizhebel schwenkbar sind. Im Öffnungszustand klaffen die Backen auch an ihrer Unterseite weit auseinander. Der Kreuzverbinder kann in den Backen während des Klemmvorganges nur in Sollposition gehalten werden, weil in Backenmitte, quer zur Zangenöffnung, eine sich über die Gesamtbackentiefe erstreckende Nut eingelassen ist, in denen die im aktuellen Klemmvorgang nicht umzuformenden Enden des Kreuzverbinders ruhen. Ohne diese Justiernut für die speziell geformten Kreuzverbinder wäre die Handhabung der Zange sehr umständlich.Finally, in FR-PS 774948 pliers for pressing a cross connector with ends are U-shaped Cross section for orthogonally aligned individual rods, which together form a cross point, described. The pliers levers are connected to each other in a first joint and each have a second joint, on which spreading levers are pivotally mounted on the one hand. At their other ends, the spreading levers have jaws which, in the closed state, have an O-shaped opening - corresponding to the circular circumference of one end of the cross connector - and can be pivoted about a joint of the two spreading levers located below the jaws. When open, the jaws also gap widely on their underside. The cross connector can only be held in the jaws in the desired position during the clamping process, because in the middle of the jaw, transversely to the jaw opening, there is a groove that extends over the entire jaw depth and in which the ends of the cross connector, which are not to be formed in the current clamping process, rest. Without this adjustment groove for the specially shaped cross connector, the pliers would be very difficult to handle.
Schließlich ist aus der GB-A-1 132 732 ein H-förmiger Blechkörper bekannt, mit dem randständige benachbarte Vertikalstäbe zweier Gittermatten mit Abstand zueinander verbindbar sind. Damit sollen Gittermatten, beispielsweise auch von Zäunen an ihren Randmaschen rechtwinklig verbunden werden, indem die Randteile des Blechkörpers zugleich oberhalb und unterhalb von Horizontalstäben um die Vertikalstäbe gebogen werden.Finally, an H-shaped sheet metal body is known from GB-A-1 132 732, with which adjacent vertical bars of two lattice mats can be connected at a distance from one another. Lattice mats, for example also of fences, are to be connected at right angles to their edge meshes by simultaneously bending the edge parts of the sheet metal body above and below horizontal bars around the vertical bars.
In der US-A- 3 220 518 wird vorgeschlagen, mittels hakenförmiger Drahtclips und Riegelstifte zwei überlappende, benachbarte Gittermatten an deren Kreuzpunkten durch Umschlingen der Vertikal- und Horizontalstäbe zu verbinden.In US-A-3,220,518 it is proposed to use hook-shaped wire clips and locking pins to overlap two adjacent grid mats on theirs To connect cross points by looping the vertical and horizontal bars.
Von daher liegt der Erfindung das Problem zugrunde, eine kaum wahrnehmbare Mattenverbindung für Zäune vorzuschlagen, die unabhängig ist von dem Rastermaß in dem die Zaunpfähle angeordnet werden, möglichst einfach montiert werden kann und gegen unbeabsichtigtes Lösen gesichert ist. Eine weitere Aufgabe der Erfindung ist es, ein einfaches Zaunmontageverfahren für diese Mattenverbindung mittels geeignetem Werkzeug vorzuschlagen.The invention is therefore based on the problem of proposing a barely perceptible mat connection for fences, which is independent of the grid dimension in which the fence posts are arranged, can be installed as easily as possible and is secured against unintentional loosening. Another object of the invention is to propose a simple fence assembly method for this mat connection using a suitable tool.
Das Problem wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 8 gelöst. Vorteilhafte Weiterentwicklungen der Erfindung sind in den Unteransprüchen erfaßt.The problem is solved according to the invention by the features of
Derartige Blechklemmen zur Zaunmattenverbindung können unmittelbar oberhalb und unmittelbar unterhalb zweier versetzter Horizontalstäbe an den Vertikalstäben angeordnet sein. Dies verhindert ein vertikales Verschieben der Stahlgittermatten gegeneinander.Such sheet metal clamps for fence mat connection can be arranged directly above and immediately below two offset horizontal bars on the vertical bars. This prevents the steel mesh mats from moving vertically against each other.
Eleganter wirkt noch die Lösung für die Zaunverbindung, wenn die Stahlgittermatten aus Stabilitätsgründen in horizontaler Richtung verlaufende Sicken in mindestens einer oder mehreren Maschen der Stahlgittermatte aufweisen. Dann kann im Bereich der Sicke eine dieser Blechklemmen angeordnet werden, während die zweite auf dem vertikal verlaufenden Teil der Stahlgittermatte angeordnet wird. Dadurch ergibt sich eine sichere Verbindung benachbarter Vertikalstäbe in zwei Achsen der Stahlgittermatte, so daß diese unverrückbar nebeneinander liegen.The solution for the fence connection is even more elegant if the steel mesh mats have, for reasons of stability, beads running in the horizontal direction in at least one or more meshes of the steel mesh mat. Then one of these sheet metal clamps can be arranged in the area of the bead, while the second is arranged on the vertically running part of the steel grid mat. This results in a secure connection of adjacent vertical bars in two axes of the steel mesh mat, so that they lie immovably next to each other.
Eine derartige einfache Verbindung zweier nebeneinander liegender Vertikalstäbe benachbarter Stahlgittermatten ergibt ein graziles Zaun-Bauwerk. Die Verbindung sollte sinnvoller Weise außerhalb des Bereiches eines Zaunpfostens erfolgen, da dort genügend Platz ist, um ein Werkzeug für die Montage der Zaunverbinder anzusetzen. Außerdem kann die Matte einfacher an einem Horizontal- oder Vertikal stab mit dem Pfosten vormontiert werden, wenn die Verbindung zweier Stahlgittermatten nicht vor dem Pfosten liegt und der Abstand der Zaunpfosten sowie deren Fundamente voneinander müssen nicht zentimetergenau vor der Zaunmontage festgelegt sein.Such a simple connection of two adjacent vertical bars of adjacent steel mesh mats results in a delicate fence structure. The connection should be made outside the area of a fence post, as there is enough space there to attach a tool for the assembly of the fence connector. In addition, the mat can be easily preassembled on a horizontal or vertical bar with the post if the connection between two steel mesh mats is not in front of the post and the distance between the fence posts and their foundations from one another need not be determined to the centimeter before the fence assembly.
Eine weitere Rutschsicherung gegen das vertikale Verschieben zweier Stahlgittermatten ergibt sich, wenn die zu verbindenden Vertikalstäbe mit einer Kunststoffbeschichtung versehen sind, weil dann der Reibbeiwert zwischen Stab und Verbinder wesentlich höher ist.Another anti-slip device against the vertical displacement of two steel mesh mats results if the vertical rods to be connected are provided with a plastic coating, because then the coefficient of friction between rod and connector is significantly higher.
Ein für den erfindungsgemäßen Zaun verwendbarer Zaunverbinder besteht aus einem C-förmigen Blechteil, dessen Abmessungen im wesentlichen durch die Dicke der zu verbindenden Stäbe und der Blechdicke bestimmt werden, wobei die Länge des Zaunverbinders mehr als die doppelte Dicke des Vertikalstabes betragen sollte, damit eine winkelgetreue Umformung des Zaunverbinders möglich ist und dieser während des Umformens nicht verdrillt wird. Aus Gründen der Dauerhaftigkeit wird für einen derartigen Zaunverbinder als Material Edelstahl bevorzugt.A fence connector that can be used for the fence according to the invention consists of a C-shaped sheet metal part, the dimensions of which are determined essentially by the thickness of the bars to be connected and the sheet thickness, the length of the fence connector should be more than twice the thickness of the vertical bar, so that an accurate angle Forming the fence connector is possible and this is not twisted during the forming. For reasons of durability, stainless steel is preferred as the material for such a fence connector.
Zur Montage der Gittermatten zum erfindungsgemäßen Zaun wird auch vorgeschlagen, eine spezielle Hebelzange für das Umformen der Zaunverbinder zu verwenden. Eine derartige langstielige Hebelzange mit Backen die eine gemeinsame Innenkontur aufweisen, die dem fertigen, angebrachten Zaunverbinder entspricht, weist - wie für sich bekannt - drei Gelenke auf, um eine große Kraftverstärkung mit den zwischen den Gelenken liegenden Spreizhebeln zu erzielen. Die maximale Backenöffnung entspricht der Breite der C-förmigen Blechklemme zuzüglich Fertigungstoleranz. Bei geöffneter Zange kreuzen sich die zangeneinwärts liegenden Teile der Backen, so daß sie ein Widerlager und eine Begrenzung für die Einlegetiefe der Blechklemmen bilden. Diese Form der Backen, der Zange und eine geeignete Wahl der Hebellängen läßt ein dosiertes und exaktes Zudrücken der C-förmigen Blechklemme in eine O-Form zu. Um auch werkzeugseitig kein Verkanten oder Verdrillen der der Blechklemme zuzulassen, ist jede Backe der Hebelzange mehrfach in dem direkt unterhalb des Widerlagers angeordnete Backengelenk gelagert, so daß sich auch die Backen relativ zum Gelenk nicht verdrehen können.To assemble the lattice mats for the fence according to the invention, it is also proposed to use special lever pliers for reshaping the fence connector. Such a long-handled lever pliers with jaws that have a common inner contour that corresponds to the finished, attached fence connector has, as is known per se, three joints in order to achieve a large increase in force with the spreading levers located between the joints. The maximum jaw opening corresponds to the width of the C-shaped sheet metal clamp plus manufacturing tolerance. When the pliers are open, the parts of the jaws lying inside the pliers intersect so that they form an abutment and a limitation for the insertion depth of the sheet metal clamps. This shape of the jaws, the pliers and a suitable choice of the lever lengths allows a dosed and exact pressing of the C-shaped sheet metal clamp into an O-shape. To prevent the tool from tilting or twisting to allow the sheet metal clamp, each jaw of the lever pliers is mounted several times in the jaw joint arranged directly below the abutment, so that the jaws cannot rotate relative to the joint.

In Figur 1 ist ein Zaunpfosten 10 dargestellt, an dem mittels Halter 11 eine Stahlgittermatte befestigt ist. Die Stahlgittermatte endet in der geschlossenen Randmasche 3 mit dem Vertikalstab 7. An diese Randmasche soll eine weitere Stahlgittermatte, bestehend aus maschenbildenden, kreuzweise angeordneten, an den Kreuzungspunkten miteinander verschweißten Horizontalstäben 1, 4, 5 und Vertikalstäben 2, 6 angereiht werden, die ihrerseits geschlossene Randmaschen 3 haben. Durch zwei als Blechklemmen ausgebildete Zaunverbinder 8, 9 werden die beiden Vertikalstäbe 6, 7 umschlossen und sicher gehalten. Dabei ruht der Verbinder 9 unmittelbar unter dem Horizontalstab 1, der Verbinder 8 unmittelbar über dem Horizontalstab 5, so daß ein Versetzen der beiden Randmaschen 3 in vertikaler Richtung unmöglich wird.In Figure 1, a
Figur 2 zeigt im vertikalen Schnitt durch eine Verbindungsstelle zweier Stahlgittermatten einen Vertikalstab 12 mit Horizontalstäben 13, wobei der Vertikalstab 12 so gebogen ist, daß sich eine Sicke 14 ausbildet. Diese Sicke 14 wird ausgenutzt, um einen Verbinder 30 im Bereich dieser Sicke anzuordnen, während ein zweiter Verbinder 31 in dem vertikalen Teil der Stahlgittermatte außerhalb der Sicke 14 angeordnet ist. Dadurch ergibt sich quasi eine zweiachsige Sicherung der Stahlgittermatten gegen Vertikalverschiebung. Eine Horizontalverschiebung ist bei einer Anordnung der Verbinder 30,31 um die Vertikalstäbe 12 sowieso nicht möglich.Figure 2 shows in vertical section through a connection point of two steel mesh mats a

In weiteren Spreizgelenken 21, 22 sind Spreizhebel 19, 20 schwenkbar gelagert. An den Enden der Spreizhebel 19, 20 sind die eigentlichen Werkzeugbacken 15, 16 angebracht, zum Beispiel durch Löten. Diese Backen 15, 16 sind wiederum an ihren, ein Auflager für die Basis der Blechklemme 9 bildenden, sich überschneidenden, unteren Enden 28, 29 durch ein Backengelenk 18 verbunden. Dabei ist jede Backe 15, 16 mindestens zweifach in dem Backengelenk 18 gelagert, um ein Verdrillen der Backen gegeneinander zu verhindern. Die Backen sind in geöffnetem Zustand gezeichnet. In die Backen wurde ein Zaunverbinder 9 mit der dargestellten Position eingelegt, der dort unter leichter Vorspannung der Backen gehalten und um die Vertikalstäbe 6, 7 analog der Darstellung in Figur 1 geschoben wurde. Nachdem die dargestellte Lage des Zaunverbinders 9 erreicht ist, können die Backen 15, 16 mit Hilfe der Hebel 24, 25 zusammengedrückt werden, so daß sich die Schenkel der Zaunverbinder 9 um die Vertikalstäbe 6, 7 schließen.Figure 3 shows the head of a lever pliers, consisting of the
