Abstract
The invention relates to a tie wire (1) that is characterized by a composite structure and an increased mechanical stability owing to the compact design, and that has an enlarged contact surface on the heavily loaded portions in order to prevent the tie wire (1) from breaking during cabling. The inventive tie wire (1) consists of a plastic matrix (2) in which two parallel metal wires (3) are embedded, and can be shaped in the form of a loop at both ends.
Description
Bindcdraht, insbesondere für das Binden von Armicrungseisen Binding wire, in particular for binding armature iron
Im Bauwesen nimmt Stahlbeton eine herausragende Stellung als Baumaterial ein. Seine Tragfähigkeit beruht auf der einander ergänzenden Wirkung der Bestandteile. Während die Druckkräfte vom Beton aufgefangen werden, nehmen die Stahleinlagen, die sogenannte Bewehrung, die Zug- und Schubkräfte auf. Die Bewehrung besteht meist aus über Bindedrähte miteinander verknüpften Stahlstäben, die als Armierungseisen bezeichnet werden. Die Verknüpfung der Armierungseisen erfolgt dadurch, dass Bindedrähte manuell um diese gebogen und anschliessend mit Hilfe eines Verdrillungswerkzeugs verspannt werden.In the construction industry, reinforced concrete has an outstanding position as a building material. Its load-bearing capacity is based on the complementary effect of the components. While the compressive forces are absorbed by the concrete, the steel inserts, the so-called reinforcement, absorb the tensile and shear forces. The reinforcement mostly consists of steel rods, which are connected with each other by means of binding wires, which are called reinforcing bars. The reinforcing bars are linked by manually twisting the binding wires around them and then tightening them using a twisting tool.
Es existieren verschiedene Ausführungen von Bindedrähten. In der einfachsten Ausführung bestehen sie aus Eisendraht oder verkupfertem Eisendraht, der an beiden Enden zu Schlaufen gebogen ist. Drähte mit endständigen Schlaufen werden im Handel oft auch als Ösendraht bezeichnet. In der Praxis werden heute Bindedrähte verwendet, die leicht verkupfert sind. Die Verkupferung ändert allerdings nur das optische Erscheinungsbild, da die Drähte trotzdem weiterhin leicht rosten. Kunststoffummantelte Drähte hingegen rosten nicht und stellen aus diesem Grund eine sinnvolle Alternative zu den reinen Metalldrähten dar.There are different types of binding wires. In the simplest version, they consist of iron wire or copper-plated iron wire, which is bent into loops at both ends. Wires with terminal loops are often referred to as eyelet wire in the trade. In practice, binding wires that are easily copper-plated are used today. However, the copper plating only changes the visual appearance, since the wires still rust slightly. Plastic-coated wires, on the other hand, do not rust and are therefore a sensible alternative to the pure metal wires.
Als Weiterentwicklung dieser einfachen Bindedrähte ist der in der Patentschrift CH 664 995 A5 beschriebene Bindedraht zu sehen, bei dem ein Ende über eine Verjüngung mit abschliessendem Kopf verfügt. Die Verjüngung wirkt als Sollbruchstelle, so dass der Bindedraht nach dem Verdrillen um die Armierungseisen bevorzugt an dieser Stelle abreisst und ein aufwändiges Abnehmen des Verdrillungswerkzeugs vom gespannten Bindedraht entfällt. Da der Bruch des Bindedrahtes jedoch nicht immer in dem Augenblick stattfindet, in dem d.e VrπY.erungseisen ausreichend aneinandergezogen sind, ist die Brauchbarkeit dieser Bindedrähte in der Praxis stark eingeschränkt.A further development of these simple binding wires is the binding wire described in the patent specification CH 664 995 A5, in which one end has a taper with a closing head. The taper acts as a predetermined breaking point, so that after twisting around the reinforcing bars, the binding wire tears off at this point, and there is no need to remove the twisting tool from the tensioned binding wire. However, since the breaking of the binding wire does not always take place at the moment when the iron is sufficiently drawn together, the usefulness of these binding wires is severely limited in practice.
In der Patentschrift EP 0 305 783 A1 wird ein Bindedraht beschrieben, der aus einem Drahtstück besteht, bei dem eine endständige Schlaufe und zwei Drahtstege derart mit einer Gegenschlaufe verbunden sind, dass über den Bindedraht hiπaus-
ragende Teile vermieden werden. Diese Art Bindedraht wird geschweisster Doppelbinder genannt.Patent specification EP 0 305 783 A1 describes a binding wire which consists of a piece of wire in which a terminal loop and two wire webs are connected to a counter-loop in such a way that the binding wire extends beyond the binding wire. protruding parts can be avoided. This type of binding wire is called welded double tie.
Problematisch beim Einsatz der herkömmlichen Bindedrähte bleibt ihre Reissfestigkeit beim Verdrillen. In der Praxis werden Bindedrähte mit Durchmessern von 1 ,1 mm bis 1 ,2 mm verwendet, die paarweise mit einer Schlaufe in das Verdril- lungswerkzeug eingelegt, um die zu verknüpfenden Armierungseisen gebogen sowie anschliessend mit dem Verdrillungswerkzeug verdrillt und gespannt werden. Wird nur ein Bindedraht zum Verdrillen der Armierungseisen eingesetzt, so kann es leicht zu einem Reissen des Bindedrahts entweder an der Stelle kommen, an der die Verdrillung den Armierungseisen am nächsten liegt, oder auch am Übergang zwischen der Schlaufe und dem nicht gebogenen Bereich des Drahtes. Der Vorteil der Verwendung von zwei Bindedrähten liegt darin, dass die auftretende Belastung an den kritischen Stellen aufgrund der grösseren Berührungsfläche der doppelt geführten Bindedrähte geringer ausfällt, so dass die Gefahr eines Reis- sens signifikant kleiner ist.The problem with using conventional binding wires remains their tensile strength when twisting. In practice, binding wires with diameters of 1.1 mm to 1.2 mm are used, which are inserted in pairs in the twisting tool with a loop, the reinforcing bars to be linked are bent, and then twisted and tensioned with the twisting tool. If only one binding wire is used to twist the reinforcing irons, the binding wire can easily tear either at the point where the twisting is closest to the reinforcing irons or at the transition between the loop and the non-bent area of the wire. The advantage of using two binding wires is that the stress occurring at the critical points is lower due to the larger contact area of the double-guided binding wires, so that the risk of being torn is significantly less.
Die Patentschrift CH 681 515 A5 legt einen Bindedraht dar, bei dem zwei Drahtstege parallel geführt werden, welche an den Enden zu Schlaufen umgebogen sind, um eine erhöhte mechanische Stabilität des Drahtes zu gewährleisten. Diese Entwicklung weist zwei wesentliche Nachteile auf. Setzt man den Bindedraht auf den Haken des Verdrillungswerkzeugs, wird zeitweise nur die Schlaufe eines Teildrahtes erfasst, so dass die parallel geführten Drähte auseinanderbiegen. Aus diesem Grund haben die parallel geführten Drähte denselben Nachteil wie ein einzelner Bindedraht, da der kritsche Punkt am Übergang zwischen der Schlaufe und dem nicht gebogenen Bereich des Drahtes, an dem der Drahtbinder bevorzugt reisst, weiterhin besteht. Zum anderen verhaken die Bindedrähte in der Praxis untereinander leicht an den Schlaufen und erschweren dadurch die Handhabung.The patent specification CH 681 515 A5 describes a binding wire in which two wire webs are guided in parallel, which are bent at the ends to form loops in order to ensure increased mechanical stability of the wire. This development has two major disadvantages. If you place the binding wire on the hook of the twisting tool, only the loop of a partial wire is temporarily gripped, so that the wires run in parallel bend apart. For this reason, the parallel wires have the same disadvantage as a single binding wire, since the critical point at the transition between the loop and the non-bent area of the wire, where the wire binder tears preferentially, continues to exist. On the other hand, in practice the binding wires easily get caught on the loops and make handling more difficult.
Die Verwendung der sogenannten geschweissten Doppelbinder anstelle von zwei einzelnen Bindedrähten hat den Nachteil, dass die endständigen Schlaufen nur
aus einem Teildraht geformt werden und leicht am mechanisch stark beanspruchten Ansatz der Schlaufe reissen können, bevor der Doppelbinder ausreichend um die Armierungseisen festgezogen ist.The use of so-called welded double binders instead of two single binding wires has the disadvantage that the end loops only be formed from a partial wire and easily tear at the mechanically highly stressed attachment of the loop before the double tie is sufficiently tightened around the reinforcing bars.
Die vorliegende Erfindung stellt sich nun die Aufgabe, einen Bindedraht zu schaffen, der eine hohe mechanische Stabilität während des Verdrillens aufweist, einfach zu handhaben sowie preiswert und unkompliziert in der Herstellung ist.The object of the present invention is to create a binding wire which has a high mechanical stability during twisting, is easy to handle and is inexpensive and uncomplicated to manufacture.
Die Aufgabe wird mit Hilfe der erfindungsgemässen Ausbildungsmerkmale des Patentanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der jeweils abhängigen Merkmale.The object is achieved with the aid of the inventive training features of the patent claim. Advantageous developments of the invention are the subject of the respective dependent features.
Der vorgeschlagene Bindedraht besteht aus zwei oder mehr Metalldrähten, die über die gesamte Länge des Bindedrahtes parallel geführt werden und in eine Kunststoffmatrix eingelassen sind. Die Kunststoff matrix weist einen kreisförmigen Querschnitt auf, dessen Durchmesser signifikant grösser ausfällt als derjenige der eingelassenen Metalldrähte. Zudem können aus dem kunststoffummantelten Draht nicht nur einfache geschlaufte, sondern auch geschweisste Bindedrähte hergestellt werden. Während bei herkömmlich geschlauften Bindedrähten die Enden zurückgebogen und um den Draht gewunden werden müssen, können beim geschweissten Draht die Enden zu Schlaufen zurückgebogen und anschliessend so flach an den Draht angelegt werden, dass nach dem Verschweissen des Kunststoffmantels ein stufenloser Uebergang zwischen den beiden Armen der Schlaufe vorliegt.The proposed binding wire consists of two or more metal wires which are guided in parallel over the entire length of the binding wire and are embedded in a plastic matrix. The plastic matrix has a circular cross section, the diameter of which is significantly larger than that of the embedded metal wires. In addition, not only simple looped but also welded binding wires can be produced from the plastic-coated wire. While the ends of conventionally looped binding wires have to be bent back and wound around the wire, the ends of the welded wire can be bent back into loops and then placed flat against the wire so that after the plastic sheath has been welded, a smooth transition between the two arms of the loop is present.
Der vorgeschlagene Bindedraht und die einführend beschriebene Funktionsweise sind im Folgenden anhand einer erläuternden Zeichnung dargestellt. Es zeigt:The proposed binding wire and the mode of operation described in the introduction are shown below with the aid of an explanatory drawing. It shows:
Fig. 1 einen Querschnitt durch den BindeFig. 1 shows a cross section through the bandage
Fig. 2 den vorgeschlagenen Bindedraht, in zwei AusführungenFig. 2, the proposed binding wire, in two versions
In Fig. 1 ist ein Querschnitt des Bindedrahtes 1 abgebildet. Der Bindedraht 1 be-
steht aus einer Kunststoffmatrix 2, in die zwei auf der gesamten Länge des Bindedrahtes 1 parallel geführte Metalldrähte 3 eingelassen sind. Der Bindedraht 1 besitzt einen im Verhältnis zu den Metalldrähten 3 vergrösserten Durchmesser.In Fig. 1 a cross section of the binding wire 1 is shown. The binding wire 1 loading is made of a plastic matrix 2, in which two metal wires 3 which are guided in parallel over the entire length of the binding wire 1 are embedded. The binding wire 1 has an enlarged diameter in relation to the metal wires 3.
In Figur 2 ist der vorgeschlagene Bindedraht dargestellt. Der Bindedraht 1 ist an seinen Enden als Schlaufen ausgeformt. Die Kunststoffmatrix ist an den Kontaktstellen 4 verschweisst.The proposed binding wire is shown in FIG. The binding wire 1 is shaped as loops at its ends. The plastic matrix is welded at the contact points 4.
Der vorgeschlagene Bindedraht weist gegenüber den in der Praxis verwendeten und gegenüber den in der Patentliteratur beschriebenen Bindedrähten deutliche Vorteile auf. Durch seine Kompositstruktur zeigt er eine erhöhte mechanische Stabilität, ohne jedoch wesentlich aufwändiger in der Herstellung als die üblichen Bindedrähte zu sein. Die mechanische Stabilität macht sich besonders bei der starken mechanischen Beanspruchung an den kritischen Stellen während des Verdrillens bemerkbar. Durch die ausgedehntere Kontaktfläche aufgrund des grösseren Durchmessers des Bindedrahtes verringert sich die Belastung der kritischen Bereiche trotz vergleichbar auftretender Kräfte. Damit lässt sich das unerwünschte Einschneiden und Reissen des Bindedrahtes vermeiden, das in der Regel zu einer ungenügenden Verknüpfung der Armierungseisen führt. Weiterhin vergrössert der Kunststoffmantel nicht nur den Radius der Verdrillung und die Kontaktfläche an den stark beanspruchten Bereichen des Bindedrahtes, sondern führt zu einer besseren Verteilung der auftretenden Kräfte, da der Kunststoffmantel während des Verdrillens als zusätzliches Polster wirkt, welches die Belastung der einzelnen Me- talldrähte teilweise ausgleichen kann. Somit können aus der Sicht der Handwerker aufgrund der grösseren mechanischen Stabilität des Bindedrahts höhere Zugkräfte aufgewendet und festere Verknüpfungen der Armierungseisen erreicht werden. Da der Bindedraht deutlich leichter handhabbar ist als herkömmliche Bindedrähte, kann das Einlegen des Bindedrahtes in das Verdrillungswerkzeug, das Umbiegen um die Armierungseisen und das Spannen mit Hilfe des Verdrillungswerkzeugs zudem ohne Ablegen der Arbeitshandschuhe erfolgen. Ein weiterer wichtiger Vorteil des vorgeschlagenen Bindedrahts ist zudem, dass die herkömmlichen Ausbil-
düngen der Bindedrähte mit kreisförmigem Querschnitt und endständigen gebogenen beziehungsweise geschweissten Schlaufen beibehalten werden können, so dass die gewohnten Arbeitsschritte weiterhin auszuüben sind und das herkömmliche Verdrillungswerkzeug weiter verwendet werden kann. Der geschlaufte Bindedraht kann in der üblichen Art hergestellt und eingesetzt werden. Beim geschweissten Bindedraht dagegen kann der Draht auf einfache Art an den Enden zu Schlaufen gebogen, an der Kontaktstelle 4 der Schlaufen erwärmt und leichtem Druck ausgesetzt werden. Der für die Ummantelung verwendete thermoplastische Kunststoff bildet an der Kontaktstelle 4 eine flache und dauerhafte Verbindung aus, so dass das zur Stabilisierung notwendige Umbiegen und Überstehen des Bindedrahtes an der Kontaktstelle 4 entfällt. Dies macht sich bei der täglichen Arbeit vorteilhaft bemerkbar, da sich die Bindedrähte nicht mehr ineinander verhaken.
The proposed binding wire has clear advantages over the binding wires used in practice and over the binding wires described in the patent literature. Due to its composite structure, it shows increased mechanical stability, but without being much more complex to manufacture than the usual binding wires. The mechanical stability is particularly noticeable in the case of the high mechanical stress at the critical points during the twisting. Due to the larger contact area due to the larger diameter of the binding wire, the load on the critical areas is reduced despite comparable forces. This avoids the unwanted cutting and tearing of the binding wire, which usually leads to an insufficient connection of the reinforcement bars. Furthermore, the plastic sheath not only increases the radius of the twist and the contact area at the highly stressed areas of the binding wire, but also leads to a better distribution of the forces that occur, since the plastic sheath acts as an additional cushion during the twisting, which stresses the individual metal wires can partially compensate. From the craftsmen's point of view, higher tensile forces can be applied due to the greater mechanical stability of the binding wire, and stronger links between the reinforcing bars can be achieved. Since the binding wire is much easier to handle than conventional binding wires, the insertion of the binding wire into the twisting tool, the bending around the reinforcing bars and the tensioning with the help of the twisting tool can also be done without removing the work gloves. Another important advantage of the proposed binding wire is that the conventional training fertilization of the binding wires with a circular cross-section and terminal bent or welded loops can be maintained, so that the usual work steps can still be carried out and the conventional twisting tool can continue to be used. The looped binding wire can be manufactured and used in the usual way. In contrast, in the welded binding wire, the wire can be bent into loops at the ends in a simple manner, heated at the contact point 4 of the loops and subjected to slight pressure. The thermoplastic used for the sheathing forms a flat and permanent connection at the contact point 4, so that the bending and protruding of the binding wire necessary for stabilization at the contact point 4 is eliminated. This is noticeably noticeable in daily work, since the binding wires no longer get caught in one another.
