Description

Technical area

The The invention relates to the production of false ceilings in tunneling.

false ceilings in tunneling and passage openings through these serve a channel for the discharge of smoke possible tunnel fires to accomplish. This will be relatively close below the tunnel ceiling Sectionally constructed along the tunnel formwork, on the the reinforcements and then the concrete, preferably self-compacting concrete, is applied. The delivery of the reinforcements and the placing of the concrete happen with different devices.

The Applying the reinforcements and the concrete to the formwork happens by workers who due to the short distance to the tunnel ceiling always have to work bent. High downtime due to illness is the result.

Object of the invention

task The invention is the introduction of the reinforcements and the concrete to enable with less staff effort.

Presentation of the invention

The The object is specified by that in the characterizing part of claim 1 Characteristics solved.

The The invention provides a method and a device (manipulator) for this purpose. before, at and with the first the reinforcements and then the concrete applied from the side on the constructed formwork for the false ceiling become.

There the constructed formwork for the sake of effectiveness very long (often 25 meters) and the distance to the ceiling is relatively low (on the order of the First 1.5 meters), are crane-like boom, the front to the end the formwork are very unstable, especially what the pump bursts (recoil effects) when introducing the concrete concerns.

The The invention therefore provides for the boom of the manipulator according to the invention, which serves both the transport of the reinforcements and the concrete, temporarily attached to the tunnel ceiling at one or more places.

This happens easily by a device that works with negative pressure works, so similar a suction cup. The tunnel ceiling is relatively smooth and allowed it this device to squeeze on it. In this way The boom is stabilized under load, because shorter lever arms occur.

Of the Boom can be a rigid beam with one or more suction devices for the Tunnel ceiling, with the beam running along a rail on the attachments (Gripper for Reinforcements or concrete distribution device) are movable.

Of the But cantilever can also be telescoped and thus the promotion of the attachment serve and at one or more of its telescopic members Intake devices for the Tunnel ceiling have. The boom can also be a combination consist of telescopic part and rigid beam-shaped part on which the telescopic part is arranged displaceably.

Of the according to the invention and preferred on wheels or chains movable manipulator now provides a mounted on a skeleton Lifting device / lifting platform (for raising the reinforcements to approximate formwork height), which simultaneously has at least one of the described boom.

At the Boom is a lifting and transport device (gripper) for the Reinforcements. Furthermore he points at the same time or after a change of the attachment also still a preferably pivotable concrete distribution device, with the the concrete (preferably self-compacting concrete) from above onto the Formwork can be applied.

• 1.) Es werden die Zwischendeckenschalungen für den zu betonierenden Abschnitt der Zwischendecke im Sollabstand unter der Tunneldecke errichtet. Eine sinnvolle Länge eines solchen Abschnitts sind zum Beispiel 25 Meter.
• 2.) Der Manipulator wird neben die aufgebaute Zwischendeckenschalung gefahren/gesetzt. Auf seiner anhebbaren Plattform liegen bereits Bewehrungen, bevorzugt als Bewehrungskörbe, bereit, oder die Bewehrungen/Bewehrungskörbe werden erst später von einem anderen Transporter angeliefert und auf die Plattform gelegt, bevorzugt mitsamt einer Bewehrungspalette.
• 3.) Die Bewehrungen werden sodann bis ungefähr auf das Niveau der Zwischendeckenschalung angehoben.
• 4.) Der Ausleger fährt an der Tunneldecke entlang über die Zwischendeckenschalung hinweg und saugt sich im mittleren oder hinteren Bereich des zwischen Schalung und Tunneldecke aufgespannten Raumes an der Tunneldecke fest. Die Saugvorrichtung wird hierzu nach oben gegen die Decke gefahren, oder der Ausleger wird als Gesamtes etwas angehoben, wodurch die Saugvorrichtung gegen die Decke gepreßt wird und sich festsaugen kann.
• 5.) Ein am Ausleger entlang verfahrbarer Greifer (mechanisch oder magnetisch) packt dann die Bewehrungen/Bewehrungskörbe von der Plattform/Palette und befördert sie nacheinander an ihren Bestimmungsort auf der Schalung.

The method for producing a false ceiling in a tunnel is now as follows:

• 1.) The false ceiling formwork for the section of the false ceiling to be concreted is erected at the nominal distance below the tunnel ceiling. A reasonable length of such a section are for example 25 meters.
• 2.) The manipulator is moved / set next to the built-up false ceiling formwork. Reinforcements, preferably as reinforcing baskets, are already available on his liftable platform, or the reinforcements / reinforcing baskets are only later delivered by another transporter and placed on the platform, preferably together with a reinforcement pallet.
• 3.) The reinforcements are then raised to approximately the level of the false ceiling formwork.
• 4.) The boom moves along the tunnel ceiling over the false ceiling formwork and absorbs itself in the middle or rear area of the space between the formwork and tunnel ceiling stretched space at the tunnel ceiling. The suction device is driven upwards against the ceiling, or the boom is raised slightly as a whole, whereby the suction device is pressed against the ceiling and can be stuck.
• 5.) A gripper (mechanical or magnetic) movable along the boom then unpacks the reinforcements / reinforcing cages from the platform / pallet and carries them one after the other to their destination on the formwork.

in the Trap of a telescopic boom, in the telescoped State the reinforcements / reinforcing baskets and then by extending transported to the front, occurs after a certain extension state the suction mechanism on one of the already extended limbs in action and from this fixed state will continue then extended.

Consists the boom of a combination of telescopic part, which on a bar-shaped Rail is movable, so depending on the auftetendem lever arm either a suction device on the telescopic part or rigid bar-shaped Part become active.

In a more elaborate design the invention, the gripper is not only along the boom (or. together with it) movable and liftable and lowerable, but also movable in the horizontal at an angle to the boom to Reinforcements / reinforcement cages to bring exactly into desired position.

The Positioning of the reinforcements / reinforcing cages may be preferred by one controllable camera on the grab or boom monitors and from outside the false ceiling can be controlled. It can also be from a position (Preferred seating position) above the false ceiling formwork to be controlled. However, the position of the reinforcements / reinforcing baskets is preferred subsequently checked again by a worker.

• 6.) Sind alle Bewehrungen/Bewehrungskörbe ordnungsgemäß verlegt, zieht sich der Greifer auf den Manipulatorwagen zurück.
• 7.) Es wird nun entweder die Betonverteilervorrichtung verfahrbar am Ausleger als neues Vorsatzgerät befestigt, oder der bereits vorhandene Greifer selbst packt die Betonverteilervorrichtung.
• 8.) Die verfahrbare Betonverteilervorrichtung oder der Greifer mit der von ihm gepackten Betonverteilervorrichtung bewegt sich nun über die Zwischendeckenschalung hinweg und verteilt, bevorzugt überwacht von einer Kamera und ferngesteuert von außerhalb der Zwischendecke, an seinem jeweiligen Bestimmungsort den Beton auf der Zwischendeckenschalung. Alternativ überwachen bei einer einfacheren Ausgestaltung der Erfindung Arbeiter die Verteilung des Betons auf der Zwischendeckenschalung.
• 9.) Ist der Beton ordnungsgemäß verteilt, wird der Manipulator verfahren/versetzt. Hierzu muß natürlich der Ausleger von der Tunneldecke getrennt sein. Bevorzugt wird er hierzu über die Plattform des Manipulators eingefahren.
• 10.) Nun kann ohne Behinderung durch den Manipulator eine neue Zwischendeckenschalung errichtet werden und der Vorgang wiederholt sich.

Alternatively, the reinforcements / reinforcing baskets that the gripper transports are manually moved to the correct position by workers.

• 6.) If all reinforcements / reinforcement cages are properly laid, the gripper retracts onto the manipulator carriage.
• 7.) It is now either the concrete distribution device movably attached to the boom as a new attachment, or the existing gripper itself grabs the concrete distribution device.
• 8.) The movable concrete distributor device or the gripper with the concrete distributor device packed by it now moves across the false ceiling formwork and distributes, preferably monitored by a camera and remotely from outside the false ceiling, at its respective destination the concrete on the false ceiling formwork. Alternatively, in a simpler embodiment of the invention, workers monitor the distribution of the concrete on the false ceiling formwork.
• 9.) If the concrete is properly distributed, the manipulator is moved / offset. For this purpose, of course, the boom must be separated from the tunnel ceiling. For this purpose, it is preferably retracted via the platform of the manipulator.
• 10.) Now, without obstruction by the manipulator, a new false ceiling formwork can be built and the process is repeated.

The Figures illustrate the method using a manipulator whose Boom a combination of telescopic section and bar-shaped rail represents, on which the telescopic part slidably disposed is.

1 shows schematically how the multipurpose manipulator according to the invention positions a reinforcement cage on the false ceiling formwork, wherein the boom, on which the gripper sits, is sucked in at a location on the tunnel ceiling.

2 shows how the same manipulator also applies the concrete.
