Description

Hohlraumausbau unter Anwendung von Ankern. Cavity lining using anchors.

Die Erfindung bezieht sicht auf einen Hohlraumausbau unter Anwendung von Ankern. The invention relates to a void construction using of anchors.

Solche Anker werden zur Sicherung von Teilen des Ausbrucksprofiles, gegebenenfalls im Zusammenwirken mit größere Profilteile umfassenden Gittermatten angewendet. Such anchors are used to secure parts of the breakout profile, possibly in cooperation with grid mats comprising larger profile parts applied.

Aufgabe der Erfindung ist es nun, den verschiedenen örtlichen Gegebenheiten, statischen Erfordernissen und technischen Wünschen sowie deren Veränderungen Rechnung tragen zu können, ohne daß es eines geankerten, geschlossenen Stahlausbaues entlang des gesamten Hohlraumprofiles bedarf. Als örtliche Gegebenheiten seien vor allem die Gesteins- und Gebirgsverhältnisse sowie die Hohlraumform und Hohlraum größe genannt.The object of the invention is now to the various local conditions, static requirements and technical wishes as well as their changes to be able to carry without it along an anchored, closed steel structure the entire cavity profile is required. As local conditions are above all the rock and rock conditions as well as the shape and size of the cavity called.

Die Erfindung löst die Aufgabe dadurch, daß im Bereich einzelner oder mehrerer Anker als Einheiten vorfabrizierte schuppenartig voneinander getrennte Drahtgittermatten angeordnet sind. The invention solves the problem that in the area of individual or several anchors prefabricated as units, separated from one another like scales Wire mesh mats are arranged.

Durch die erfindungsgemäße schuppenartige Anordnung von Drahtgittermatten ist eine besonders wirtschaftliche Bauweise möglich, indem einzelne Anker nur zur Verankerung blockiger oder rolliger Ausbruchlaibungen, andere Anker zur Anordnung einer einzelnen Drahtgittermatte je Anker und wieder andere Anker zur gemeinsamen Verbindung durch eine einzige Drahtgittermatte herangezogen werden können. Due to the scale-like arrangement of wire mesh mats according to the invention a particularly economical construction is possible by using individual anchors only for Anchoring of blocky or roll-like excavation reveals, other anchors for arrangement a single wire mesh mat per anchor and again other anchors to the common Connection can be used by a single wire mesh mat.

Im Zuge des endgültigen Hohlraumausbaues oder der Hohlraumverkleidung kann das Drahtskelett der Matten mit Baustoffen ausgefacht werden oder/und als Bewehrung für einen Betonausbau dienen. In the course of the final expansion of the cavity or the lining of the cavity the wire skeleton of the mats can be filled with building materials and / or as reinforcement serve for a concrete expansion.

In der Zeichnung zeigt Pig. 1 einen schematischen Querschnitt'durch ein Ausbruchsprofil mit dem erfindungsgemäßen schuppenartigen Ausbau. In einer Seitenansicht zeigt Fig. 2 eine Drahtgittermatte in einer vorteilhaften Ausbildung. In the drawing shows Pig. 1 a schematic cross-section through an outbreak profile with the scale-like expansion according to the invention. In a side view Fig. 2 shows a wire mesh mat in an advantageous embodiment.

Im Ausbruchsprofil sind Fels- oder Erdanker 4 vorgesehen. Im linken und rechten Abschnitt der Darstellung trägt jeder Anker nur eine einzelne Drahtgittermatte 5e In der Firstpartie der Profildarstellung sind je zwei Anker 4 durch je eine gemeinsame Drahtgittermatte 6 verbunden. Auf diese Weise kann erwünschtenfalls eine nachgiebige Verbindung zwischen einzelnen Matten erzielt werden. Rock or ground anchors 4 are provided in the breakout profile. In the left In the right-hand section of the illustration, each anchor carries only a single wire mesh mat 5e In the first part of the profile representation, two anchors 4 are each through one common Wire mesh mat 6 connected. In this way, if desired, a compliant Connection between individual mats can be achieved.

Als Drahtgittermatten werden gemäß Fig. 2 dreidimensionale IIatratzen verwendet, welche als gekrtinmte, etz der Hohlraumprofilform angepaßte Körper hergestellt sind und ausschließlich aus Drähten 1, 2, 3 bestehen. Die aus der Darstellung ersichtlichen Welldrähte 1 bestimmen den dreidimensionalen Aufbau der Matratzen. Die Welldrahtserien sind durch Querdrähte 2 miteinander verbunden; senkrecht dazu verlaufen in mehr oder weniger größeren Abständen Ringdrähte 3. As shown in FIG. 2, three-dimensional mattresses are used as wire mesh mats used, which are manufactured as a molded body that is adapted to the shape of the hollow profile and consist exclusively of wires 1, 2, 3. The ones from the depiction The corrugated wires 1 shown determine the three-dimensional structure of the mattresses. The corrugated wire series are connected to one another by transverse wires 2; perpendicular to it Ring wires 3 run at more or less greater intervals.

Die Weite der durch die Drähte 1, 2, 3 gebildeten Maschen ist so groß, daß eih hufschieben auf die Stangen der Anker ohne jedwede Vorbereitung möglich ist. The width of the meshes formed by the wires 1, 2, 3 is like this great that you can slide your hoof onto the rods of the anchors without any preparation is.
