Abstract

The invention relates to reinforcing mesh with double transverse struts.

Description

BEWEHRUNGSMATTE MIT DOPPELTEN QUERSTREBEN FÜR  REINFORCEMENT MAT WITH DOUBLE CROSS STRAPS FOR
GEKRÜMMTE BAUKÖRPER  STRUCTURED CONSTRUCTION BODIES
Die Erfindung betrifft eine Bewehrung aus Stahl für gekrümmte Baukörper, bestehend aus einander rechtwinkelig kreu- zenden und an den Kreuzungspunkten miteinander zu einem Gitter verschweißten Längs- und Querdrähten. The invention relates to a reinforcement made of steel for curved structures, consisting of mutually perpendicular cross and welded together at the intersection points to a grid longitudinal and transverse wires.
Derartige Gitter aus Stahldraht werden für zahlreiche Arten von Betonbewehrungen verwendet.  Such steel wire meshes are used for many types of concrete reinforcement.
Die Erfindung zielt auf die Schaffung eines Bewehrungsgit- ters ab, das als Bewehrung für die Auskleidung von Tunnelbauten, insbesondere zur Sicherung von Spritzbeton, oder anderen Bauwerken mit bogenförmiger bzw. gekrümmter Form eingesetzt werden kann.  The invention aims to provide a reinforcing grid, which can be used as a reinforcement for the lining of tunnels, in particular for securing shotcrete, or other structures with arcuate or curved shape.
Die erfindungsgemäße Bewehrung der einleitend angegebenen Art zeichnet sich dadurch aus, daß die Längsdrähte des Gitters in regelmäßigen Abständen mit Aufbiegungen versehen sind, und die Querdrähte auf der Seite der Aufbiegungen jeweils zu beiden Seiten einer Aufbiegung angeordnet sind.  The reinforcement according to the invention of the type described in the introduction is characterized in that the longitudinal wires of the grid are provided at regular intervals with bends, and the transverse wires are arranged on the side of the bends respectively on both sides of a bend.
Vorzugsweise ist das Gitter in seiner Längsrichtung in ei- ne vorbestimmte Bogenform biegbar, in welcher die Aufbiegungen auf der Außenseite der Bogenform liegen.  Preferably, the grid is bendable in its longitudinal direction in a predetermined arcuate form, in which the bends are on the outside of the arch form.
Infolge der Äufbiegungen bestimmt es die Tiefe der z.B. im Spritzverfahren auf die Tunnelwand oder eine andere gekrümmte Bauwerkfläche aufzubringenden Betonschicht.  As a result of the bends it determines the depth of the e.g. sprayed on the tunnel wall or other curved surface to be applied concrete layer.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert, die in Fig. 1 eine Draufsicht, in Fig. 2 eine Seitenansicht der erfindungsgemäßen Bewehrung und in Fig. 3 das Detail A aus Fig. 2 zeigt.  The invention will be explained in more detail below with reference to an exemplary embodiment with reference to the drawing, which shows in FIG. 1 a plan view, in FIG. 2 a side view of the reinforcement according to the invention and in FIG. 3 the detail A of FIG.
Das in Fig. 1 dargestellte rechteckige Bewehrungsgitter besteht aus an ihren Kreuzungspunkten miteinander verschweiß- ten Längsdrähten 1 und Querdrähten 2 aus Stahl. Wie die Zeichnung in Fig. 3 zeigt, sind die Querdrähte 2 jeweils zu beiden Seiten von regelmäßig beabstandeten Aufbiegungen 3 angeordnet. The rectangular reinforcement grid shown in FIG. 1 consists of welded joints at their points of intersection. th longitudinal wires 1 and 2 cross wires made of steel. As the drawing in Fig. 3 shows, the transverse wires 2 are arranged in each case on both sides of regularly spaced bends 3.
Das Bewehrungsgitter kann in beliebigen, nur durch die Produktionsmaschinen begrenzten Längen und Breiten hergestellt werden .  The reinforcing grid can be made in any lengths and widths limited only by the production machines.
Für den praktischen Einsatz zum Bewehren einer etwa der Höhe der Aufbiegungen 3 entsprechenden Betonschicht, insbesondere Spritzbetonschicht, z.B. für eine Tunnelauskleidung, wird das Gitter entsprechend gebogen und an die Tunnelwand angelegt, worauf Beton aufgespritzt wird. Infolge der Aufbiegungen 3 ist eine bessere Längsverschieblichkeit der Längsdrähte 1 gegeben. Dadurch können Längsstauchungen (z.B. infolge des steigenden Gebirgsdruckes ) im erstarrenden Spritzbeton besser abgefangen werden und führen zu keinen Schubabplatzungen im Spritzbeton .  For practical use for reinforcing a concrete layer corresponding approximately to the height of the bends 3, in particular shotcrete layer, e.g. for a tunnel lining, the grid is bent accordingly and applied to the tunnel wall, whereupon concrete is sprayed on. As a result of the bends 3 a better longitudinal displacement of the longitudinal wires 1 is given. As a result, longitudinal compressions (for example, as a result of the rising rock pressure) can be better absorbed in the solidifying shotcrete and do not lead to any thrust in the shotcrete.
Das Bewehrungsgitter eignet sich natürlich auch für andere bogenförmige bzw. gekrümmte Baukörper.  Of course, the reinforcement grid is also suitable for other arched or curved structures.
