Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft ein Verfahren zur pneumatischen Manipulation eines Betonbauteils mit in dem Betonbauteil integrierter und im Querschnitt im Wesentlichen C-förmiger Ankerschiene mit einem zur Außenseite des Betonbauteils weisendem Ankerschienenschlitz, wobei in die Ankerschiene ein Füllstoff eingebracht wird, wobei zumindest ein pneumatisches Hebeelement auf das Betonbauteil zumindest auf einen die Ankerschiene enthaltenden Teilbereich gesetzt wird, so dass sich die Ankerschiene zumindest teilweise unter dem pneumatischen Hebeelement befindet, wobei in dem durch das pneumatische
Hebeelement und das Betonbauteil gebildeten abgeschlossenen Volumen ein Unterdruck erzeugt wird, wobei das Füllelement entweder über mindestens den Bereich der Ankerschiene ausgeführt ist, der von dem Unterdruck betroffen ist oder, bei mit zusätzlichen Füllelementen geschlossenen Querschnittsteilen, welche nach Einbringung des Füllelements weiterhin offen sind, gezielt nur dort eingesetzt wird, wo eine Dichtung des pneumatischen Hebeelementes ansetzt, wobei
durch Betätigung des pneumatischen Hebeelements mit daran angesaugtem Betonbauteil das Betonbauteil angehoben und an einen Zielort und in eine Zielposition bewegt wird, wobei der Unterdruck in dem abgeschlossenen Volumen soweit abgeschwächt wird, bis dass das Betonbauteil und das pneumatische Hebeelement voneinander trennbar sind, und wobei anschließend der Füllstoff aus der Ankerschiene zumindest teilweise entfernt wird.The invention relates to a method for the pneumatic manipulation of a concrete component with integrated in the concrete component and in cross-section substantially C-shaped anchor rail with pointing to the outside of the concrete component anchor rail slot, wherein in the anchor rail, a filler is introduced, wherein at least one pneumatic lifting element on the concrete component is placed at least on a portion containing the anchor rail portion so that the anchor rail is at least partially below the pneumatic lifting element, wherein in which by the pneumatic
Lifting element and the concrete component formed closed volume a negative pressure is generated, wherein the filling element is carried out either over at least the region of the anchor rail, which is affected by the negative pressure, or, in closed with additional filling elements cross-sectional parts, which are still open after introduction of the filling element targeted is used only where a seal of the pneumatic lifting element attaches, wherein
by actuating the pneumatic lifting element with concrete component drawn thereon, the concrete component is lifted and moved to a destination and a target position, wherein the negative pressure in the closed volume is weakened until the concrete component and the pneumatic lifting element are separable from each other, and then the Filler from the anchor rail is at least partially removed.

Stand der Technik und Hintergrund der Erfindung Die pneumatische Hebetechnologie ist in verschiedenen bereichen wohl bekannt, sei es in der automatischen Fertigung im Rahmen der Robotik, zum Heben von Coils, aber auch für große und schwere Bauteile, beispielsweise aus Beton. Dabei ist das Prinzip dadurch gekennzeichnet, dass auf ein zu handhabendes Bauteil ein Saugnapf oder eine Saugglocke aufgesetzt wird und zwischem dem Bauteil und dem Saugnapf bzw. der Saugglocke ein Unterdruck erzeugt wird. Je nach Maß des Unterdrucks in Verbindung mit der Fläche des Bauteils, in welcher dieser Unterdruck wirkt, entsteht eine Haltekraft zwischen Bauteil und Saugnapf bzw. Saugglocke, welche die Gewichtskraft des Bauteils erreicht und überschreitet. Durch Bewegung des Saugnapfes bzw. der Saugglocke kann das Bauteil dann manipuliert werden, i.e. an einen Zieort und eine Zielposition verbracht werden. Solch ein Saugnapf bzw. Saugglocke wird folgend als pneumatisches Hebeelement bezeichnet.PRIOR ART AND BACKGROUND OF THE INVENTION Pneumatic lifting technology is well known in various fields, be it automated robotics manufacturing, coil lifting, but also large and heavy components such as concrete. The principle is characterized in that a suction cup or a suction cup is placed on a component to be handled and between the component and the suction cup or the suction cup a negative pressure is generated. Depending on the degree of negative pressure in conjunction with the surface of the component in which this negative pressure acts, a holding force is produced between the component and the suction cup or suction cup, which reaches and exceeds the weight of the component. By moving the suction cup, the component can then be manipulated, i. be moved to a draw location and a destination location. Such a suction cup is referred to below as a pneumatic lifting element.

Ein solches pneumatisches Hebelelement ist typischerweise Teil einer Manipulationsvorrichtung und an einem meist in allen drei Raumdimensionen, zumindest einer, bewegbaren Manipulatorarm befestigt. Oftmals kann das pneumatische Hebeelement gegenüber dem Manipulatorarm auch eine Rotationsbewegung ausführen. Weitere Teile einer solchen Manipulationsvorrichtung umfassen Mittel zur Erzeugung eines Unterdrucks, typischerweise eine Vakuumpumpe, und pneumatischen Leitungen, Rohre, Schläuche und dergleichen, durch welche Gas bzw. Luft von dem Inneren des pneumatischen Hebeelements in Richtung der Saugeinlasses der Mittel zur Erzeugung eines Unterdrucks gefördert wird, wodurch im durch das Bauteil mit aufgesetztem pneumatischen Hebeelement gebildeten Volumen der gewünschte Unterdruck erzeugt wird. Weiterhin umfasst eine solche Manipulationsvorrichtung typischerweise mechanische, hydraulische und/oder pneumatische Mittel zur Bewegung des Armes in den gewünschten Freiheitsgraden.Such a pneumatic lever element is typically part of a manipulation device and attached to a usually in all three space dimensions, at least one, movable manipulator arm. Often, the pneumatic lifting element relative to the manipulator also perform a rotational movement. Other parts of such a manipulating device include means for generating a negative pressure, typically a vacuum pump, and pneumatic lines, pipes, hoses and the like, through which gas or air from the interior of the pneumatic lifting element in the direction of the suction inlet the means for generating a negative pressure is conveyed, whereby in the volume formed by the component with attached pneumatic lifting element, the desired negative pressure is generated. Furthermore, such a manipulation device typically comprises mechanical, hydraulic and / or pneumatic means for moving the arm in the desired degrees of freedom.

Ein grundsätzliches Problem besteht in der Dichtheit zwischen pneumatischem Hebeelement und zu hebendem Bauteil, weil eine angeschlossene Unterdruckpunmpe eine Förderleistung habe muss, welche ausreicht, um auch trotz Leckströme an Luft zwischen dem Bauteil und dem aufgesetzten pneumatischen Hebeelement einen vorgegebenen Unterdruck in hinreichendem Maß zu erzeugen. Dies ist insbesondere problematisch bei Betonbauteilen mit darin integrierten Ankerschienen, weil ein pneumatisches Hebeelement kaum dergestalt ausbildbar ist, jedenfalls unter vertretbarem technischen und wirtschaftlichem Aufwand, dass seine Abdichtung zum Bauteil hin auch bis in den Grund und in den Hinterschnitt eines Ankerschienenschlitzes reicht. Die Längsrichtung des Ankerschienenschlitzes kann somit einen Luftkanal zwischen dem von dem Hebeelement und dem Bauteil gebildeten Volumen und der Außenatmosphäre bilden mit der Folge kaum beherrschbarer großer Leckströme.A fundamental problem is the tightness between the pneumatic lifting element and to be lifted component because a connected Unterdruckpunmpe must have a flow rate which is sufficient to produce a predetermined negative pressure in spite of leakage currents in air between the component and the attached pneumatic lifting element to a sufficient extent. This is particularly problematic in concrete components with integrated anchor channels, because a pneumatic lifting element is barely formable, at least under reasonable technical and economic effort that his seal to the component also extends into the bottom and the undercut of an anchor rail slot. The longitudinal direction of the anchor rail slot can thus form an air channel between the volume formed by the lifting element and the component and the outside atmosphere with the result of hardly controllable large leakage currents.

Aus der Praxis ist ein Verfahren bekannt, wobei Füllstoffe in die Ankerschiene bzw. den Ankerschienenschlitz eingearbeitet werden, beispielsweise Hartschäume oder Gips. Dieser Füllstoff
muss dann später mühsam wieder aus dem Ankerschienenschlitz entfernt bzw. heraus gekratzt werden. Zudem ist die Unterdruckstabiltät beispielsweise von solchen Schäumen problematisch. Schließlich ist deren Einbringung umständlich und zeitaufwändig, nicht zuletzt aufgrund der notwendigen Aushärtezeit.From practice, a method is known, wherein fillers are incorporated into the anchor rail or the anchor rail slot, such as rigid foams or gypsum. This filler
must then later laboriously removed from the anchor rail slot or scratched out. In addition, the Unterdruckstabiltät example of such foams is problematic. Finally, their introduction is cumbersome and time consuming, not least because of the necessary curing time.

Technisches Problem der ErfindungTechnical problem of the invention

Der Erfindung liegt daher das technische Problem zugrunde, ein Verfahren zur pneumatischen Manipulation eines Betonbauteils mit integrierter Ankerschiene anzugeben, welches einfach, kostengünstig und zuverlässig ausführbar ist.The invention is therefore the technical problem of providing a method for pneumatic manipulation of a concrete component with integrated anchor rail, which is simple, inexpensive and reliable executable.

Grundzüge der Erfindung und bevorzugte AusführungsformenBroad features of the invention and preferred embodiments

Zur Lösung dieses technischen Problems lehrt die Erfindung ein Verfahren nach Anspruch 1.To solve this technical problem, the invention teaches a method according to claim 1.

Eine C-förmige Ankerschiene im Sinne der Erfindung umfasst verschiedene Detailformen mit im Querschnitt betrachtet geraden Teilbereichen oder auch gekrümmt verlaufenden Teilbereichen, beispielsweise insgesamt in Elipsenform. In jedem Fall weist die Ankerschiene einen in Längsrichtung verlaufenden Ankerschienenschlitz auf, dessen Schlitzweite B (s. beispielsweise Figur 3) kleiner als die Innenraumbreite U ist. Dadurch sind die beiden Enden des "C" einander zugewandt und es lassen sich Bauteile mit einer Länge von mehr als die Schlitzweite B in den Ankerschienenschlitz einführen und um 90° drehen, wodurch ein solches Bauteil dann mit seinen Längsenden die im Querschnitt der Ankerschiene ersichtlichen nach innen weisenden Enden des "C" hintergreift. Diese typische Ausbildung von Ankerschienen wird im Rahmen der Erfindung genutzt.A C-shaped anchor rail in the sense of the invention comprises various detail forms with subareas that are straight in cross section or also curved subareas, for example in total in elliptical form. In any case, the anchor rail has a longitudinal direction extending anchor rail slot, whose slot width B (see, for example, Figure 3) is smaller than the interior width U. Thus, the two ends of the "C" facing each other and it can be components with a length of more than the slot width B in the anchor rail slot and rotate 90 °, whereby such a component then with its longitudinal ends apparent in the cross section of the anchor rail after inside pointing ends of the "C" behind. This typical formation of anchor channels is used in the invention.

Beim erfindungsgemäßen Verfahren kann das Füllelement bereits vor der Betonage des Betonbauteils in die Ankerschiene eingesetzt werden und ersetzt dann (zusätzlich) ganz oder teilweise eine Füllung des Standes der Technik, die das Eindringen von Frischbeton in den Ankerschienenschlitz verhindert.In the method according to the invention, the filling element can be inserted into the anchor rail before the concreting of the concrete component and then (additionally) completely or partially replaces a filling of the state of the art, which prevents the penetration of fresh concrete into the anchor rail slot.

Das Füllelement in der Anwendung der Erfindung dichtet den Ankerschienenschlitz ab, so dass hierüber kein Luftstrom (insbesondere in Richtung der Querschnittsebene des Ankerschienenschlitzes, aber ggf. in Längsrichtung der Ankerschiene) möglich ist. Um einen Luftstrom durch den Querschnitt der Ankerschiene (also in deren Längsrichtung) zu verhindern, wird das Füllelement entweder über mindestens den Bereich der Ankerschiene ausgeführt, der von einem Unterdruck betroffen sein wird oder gezielt nur dort eingesetzt, wo die Dichtung des pneumatischen Hebeelements ansetzt. Bei letzterer Variante müssen die Querschnittsteile, die nach Einbringen des eigentlichen Füllelements weiterhin offen sind, mittels zusätzlicher Füllelemente o. ä. geschlossen werden. Das Füllelement kann auch bereits vor der Betonage des Bauteils eingesetzt werden und ersetzt dann ganz oder teilweise die Füllung, die das Eindringen von Frischbeton in den Ankerschienenschlitz verhindert.The filling element in the application of the invention seals the anchor rail slot, so that no air flow (in particular in the direction of the cross-sectional plane of the anchor rail slot, but possibly in the longitudinal direction of the anchor rail) is possible. In order to prevent air flow through the cross section of the anchor rail (ie in the longitudinal direction), the filling element is carried out either over at least the region of the anchor rail, which will be affected by a negative pressure or selectively used only where the seal of the pneumatic lifting element attaches. In the latter variant, the cross-sectional parts, after insertion of the actual Filling element are still open, by means of additional filling elements o. Ä. Closed. The filling element can also be used before the concreting of the component and then completely or partially replaced the filling that prevents the ingress of fresh concrete in the anchor rail slot.

Ein Vorteil der Erfindung besteht darin, dass sich aufgrund der Ausbildung des Füllelements und dessen gummielastischen Eigenschaften ein Ankerschienenschlitz in einer Ebene der Oberfläche des Betonbauteiles abdichten läßt. Dadurch kann ein pneumatisches Hebeelement an beliebiger Stelle des Betonbauteils aufgesetzt werden, ohne dass störende Leckströme durch den Ankerschienenschlitz bzw. den darunter liegenden Kanal den erzeugten Unterdruck nennenswert mindern können. Andererseits ist ein solches Füllelement aufgrund seiner gummielastischen Eigenschaften nach der Manipulation des Betonbauteils auch leicht durch Herausziehen von einem oder von beiden Enden her wieder entfernbar. Insgesamt werden eine erhöhte Sicherheit, Zuverlässigkeit in Verbindung mit arbeitschritt- und kostenmäßigen Erleichterungen erreicht.An advantage of the invention is that due to the formation of the filling element and its rubber-elastic properties, an anchor rail slot can be sealed in a plane of the surface of the concrete component. Thereby, a pneumatic lifting element can be placed anywhere on the concrete component, without disturbing leakage currents through the anchor rail slot or the underlying channel can significantly reduce the negative pressure generated. On the other hand, such a filling element is due to its rubber-elastic properties after the manipulation of the concrete component also easily removable by pulling from one or both ends ago. Overall, increased security, reliability in connection with labor and cost-related facilities are achieved.

Bevorzugt ist es, wenn der gummielastische Werkstoff eine Härte von Shore A im Bereich von 4 bis 80, insbesondere 8 bis 50, aufweist. Der gummielastische Werkstoff hat vorzugsweise eine Reißfestigkeit von zumindest 1 N/mm2, insbesondere zumindest 5 N/mm2.It is preferred if the rubber-elastic material has a hardness of Shore A in the range of 4 to 80, in particular 8 to 50. The rubber-elastic material preferably has a tensile strength of at least 1 N / mm 2 , in particular at least 5 N / mm 2 .

Grundsätzlich sind beliebige handelsübliche gummielastische Werkstoffe einsetzbar, wie beispielsweise thermoplastische Elastomere. Hierzu zählen beispielsweise Elastomere auf Olefinbasis (wie PP/EPDM, beispielsweise Santoprene, Sarlink, Forprene), auf Urethanbasis (wie Desmopan, Texin, Utechllan), auf Polyesterbasis bzw-Copolyester (wie Hytrel, Riteflex), Styrol-Blockcopolymere (wie SBS, SEBS, SEEPS, MBS, beispielsweise Styroflex, Septon Thermolast, oder auf Copolyamidbasis (wie PEBAX). Besonders bevorzugt ist es jedoch, wenn der Gummiwerkstoff ein Silikongummi bzw. Silikonkautschuk ist. Des Weiteren ist es möglich, dass das Füllelement als Verbundwerksoff bzw. Hybridwerkstoff ausgebildet ist. Hierzu können insbesondere Gewebe- oder Fasereinlagen beispielsweise aus organischen Polymerwerkstoffen oder Metall bzw. Stahl vorgesehen sein, beispielsweise in einem Teilbereich (bezogen auf die Längserstreckung) oder die gesamte Länge des Füllelementes durchspannend. Solche Einlagen können auch an den Enden oder zwischen den Enden eines Füllelementes aus diesem heraus ragen, insbesondere auch aus dem Ankerschienenschlitz heraus (bei in dem Ankerschienenschlitz eingebautem Füllelement). Dann bietet eine solche Einlage eine Handhabe, um das Füllelement wieder aus dem Ankerschienenschlitz herauszuziehen. Zu dem gleichen Zweck kann vor dem Einführen des Füllelements in den Ankerschienenschlitz auch ein Ausreissband in den Ankerschienenschlitz, insbesondere dessen Grund, eingelegt und ggf. dort (leicht lösbar) befestigt werden.In principle, any commercial rubber-elastic materials are used, such as thermoplastic elastomers. These include, for example, olefin-based elastomers (such as PP / EPDM, for example Santoprene, Sarlink, Forprene), urethane-based (such as Desmopan, Texin, Utechllan), polyester-based or copolyester (such as Hytrel, Riteflex), styrene block copolymers (such as SBS, SEBS, SEEPS, MBS, for example Styroflex, Septon Thermolast, or copolyamide-based (such as PEBAX), however, it is particularly preferred for the rubber material to be a silicone rubber or silicone rubber For this purpose, fabric or fiber inserts, for example, of organic polymer materials or metal or steel may be provided, for example in a partial area (relative to the longitudinal extension) or spanning the entire length of the filling element Ends of a filling element protrude out of this, in particular also from the anchor rail nschlitz out (with in the anchor rail slot built-in filler). Then such an insert provides a handle to pull the filling element out of the anchor rail slot again. For the same purpose, before the insertion of the filling element in the anchor rail slot and a tear strip in the anchor rail slot, in particular its bottom, inserted and possibly there (easily detachable) are attached.

Ein Füllelement kann massiv (im Wesentlichen) aus dem gummielastischen Werkstoff gebildet sein, oder auch Hohlräume, Kammern und dergleichen enthalten, ggf. auch als Ballondichtung ausgebildet. Ebenso kann die Oberfläche Schlitze oder Lamellen aufweisen. Solche Maßnahmen können die Kompressibilität des Füllelementes und so dessen Montierbarkeit in einer Ankerschiene ebenso verbessern, wie den späteren Ausbau des Füllelementes aus der Ankerschiene.A filling element may be solid (essentially) formed of the rubber-elastic material, or else Contain cavities, chambers and the like, possibly also designed as a balloon seal. Likewise, the surface may have slots or lamellae. Such measures can improve the compressibility of the filling element and so its mountability in an anchor rail as well as the subsequent expansion of the filling element from the anchor rail.

Im Rahmen der Erfindung kann es sich als zweckmäßig erweisen, wenn Montagehilfen eingesetzt werden. Denn das Füllelement muss gleichsam in eine Ankerschiene "eingequetscht" werden, insbesondere müssen die Rastelemente in den Ankerschienenschlitz hinein gedrückt werden. Insbesondere bei Verwendung eher harter Gummiwerkstoffe erleichtern Montagehilfen das Einsetzen des Füllelements in eine Ankerschiene. Als Montagehilfen kommen beispielsweise im Querschnitt (der Ankerschiene bzw. des Füllelementes betrachtet) trichterförmig ausgebildete Einführtrichter oder Kompressionselemente, welche ein Füllelement in der Querschnittsebene zumindest in Richtung der beiden einander gegenüberliegenden C-Schenkel der Ankerschiene komprimieren, in Frage. Solche Montagehilfen können ggf. in Längsrichtung der Ankerschiene wieder entfernt werden. Als einfachste Montagehilfe kommen natürlich geeignete Schmiermittel in Frage, wie beispielsweise Seifenlösung, Öl oder Fett, insbesondere niedrigviskose Silikonfette oder Silikonöle, in Frage, welche (vorzugsweise unmittelbar) vor dem Eindrücken auf die Ankerschiene im Bereich des Ankerschienenschlitzes und/oder auf das Füllelement aufgetragen werden.Within the scope of the invention it may prove expedient if assembly aids are used. Because the filling element must be "crushed" as it were in an anchor rail, in particular, the locking elements must be pressed into the anchor rail slot. In particular, when using rather hard rubber materials facilitate assembly aids the insertion of the filling element in an anchor rail. As mounting aids come, for example, in cross-section (the anchor rail or the filler considered) funnel-shaped insertion funnel or compression elements which compress a filler in the cross-sectional plane at least in the direction of the two opposite C-legs of the anchor rail, in question. Such mounting aids can optionally be removed again in the longitudinal direction of the anchor rail. The easiest mounting aid are, of course, suitable lubricants in question, such as soap solution, oil or fat, especially low viscosity silicone greases or silicone oils in question, which (preferably immediately) are applied to the anchor rail in the region of the anchor rail slot and / or on the filler before the impressions ,

Die Form des Füllelements, im Querschnitt der aufzurastenden Ankerschiene betrachtet, umfasst typischerweise ein Sockelteil, zwei einander gegenüberliegende Rastelemente, welche den Ankerschienenschlitz hintergreifen, und, optional, ein Stützteil, welches sich bei aufgerasteter Ankerschiene gegen den Grund des Ankerschienenschlitzes abstützt. Ein solches Füllelement kann, in Längsrichtung der Ankerschiene betrachtet, eine Länge aufweisen, welche der Länge der Ankerschiene entspricht. Dies ist insbesondere deshalb vorteilhaft, weil das Füllelement dann nur den Bereich der Öffnung des Ankerschienenschlitzes gegenüber dem Füllelement abzudichten braucht, nicht jedoch den gesamten Raum des Ankerschienenschlitzes ausfüllen muss. Es ist aber auch möglich, dass das Füllelement eine Länge aufweist, welche (nur) zumindest den Teilbereich des Betonbauteils durchspannt, auf welchen das pneumatische Hebeelement aufgesetzt wird. Wenn ein solches gegenüber der Ankerschiene verkürztes Füllement nicht über seine gesamte Länge den Ankerschienenschlitz ausfüllt, so empfiehlt es sich, wenn zumindest an den beiden Enden weitere, den Ankerschienenschlitz vollständig ausfüllende Dichtelemente, beispielsweise aus einem gummielalstischen Werkstoff, angeordnet und mit dem Füllelement verbunden oder ein Teil hiervon sind.The shape of the filling element, viewed in cross section of the anchor rail to be latched, typically comprises a base part, two opposing latching elements which engage behind the anchor rail slot, and, optionally, a support member which rests against the bottom of the anchor rail slot when the anchor rail is latched. Such a filling element may, viewed in the longitudinal direction of the anchor rail, have a length which corresponds to the length of the anchor rail. This is particularly advantageous because the filling element then only needs to seal the region of the opening of the anchor rail slot with respect to the filling element, but does not have to fill the entire space of the anchor rail slot. But it is also possible that the filling element has a length which (at least) spans at least the portion of the concrete component on which the pneumatic lifting element is placed. If such compared to the anchor rail shortened filling does not fill the anchor rail slot over its entire length, it is recommended if at least at the two ends, the anchor rail slot completely filling sealing elements, for example, from a rubber-elastic material, arranged and connected to the filler or a Part of this are.

Für die Erfindung einsetzbar ist ein Füllelement mit einem Sockelteil, mit zwei einander gegenüberliegenden Rastelementen und mit einem Stützteil, wobei die Höhe des Sockelteils der Schlitztiefe eines Ankerschienenschlitzes einer zugeordneten Ankerschiene entspricht, wobei die Rastelemente zum Hintergreifen des Ankerschienenschlitzes ausgebildet sind und wobei das Stützteil zum Anliegen an den Grund des Ankerschienenschlitzes bei aufgerasteter Ankerschiene ausgebildet ist. Das Stützteil ist vorteilhafterweise im Querschnitt durch die Rastelemente betrachtet dreieckig oder trapezförmig, in Richtung von dem Sockelteil weg sich verjüngend, ausgebildet. Hierdurch läßt sich das Füllement unschwer in den Ankerschieneschlitz einführen und darin einrasten.Can be used for the invention is a filling element with a base part, with two opposing locking elements and with a support member, wherein the height of the Base part of the slot depth of an anchor rail slot corresponds to an associated anchor rail, wherein the locking elements are designed for engaging behind the anchor rail slot and wherein the support member is formed for abutment against the bottom of the anchor rail slot with latched anchor rail. The support member is advantageously viewed in cross section through the locking elements triangular or trapezoidal, tapering in the direction of the base part, formed. As a result, the filling can be easily inserted into the anchor rail slot and engage it.

Im Folgenden wird die Erfindung anhand von lediglich ein Ausführungsbeispiel darstellenden Figuren näher erläutert. Es zeigen:

Figur 1:
ein mittels eines pneumatischen Hebeelementes angesaugtes Betonbauteil, im Querschnitt durch eine Ankerschiene betrachtet,
Figur 2:
den Gegenstand der Figur 1, im Schnitt der Ebene A-A betrachtet.
In the following the invention will be explained in more detail by means of only one embodiment illustrative figures. Show it:
FIG. 1:
a concrete component sucked by means of a pneumatic lifting element, viewed in cross section through an anchor rail,
FIG. 2:
the object of FIG. 1 , viewed on average at the level AA.

In der Figur 1 erkennt man ein Betonbauteil 1 mit in dem Betonbauteil 1 integrierter und im Querschnitt im Wesentlichen C-förmiger Ankerschiene 2 mit einem zur Außenseite des Betonbauteils 1 weisendem Ankerschienenschlitz 3. In die Ankerschiene 2 ist ein vorzugsweise geschlossenes Füllement 5 aus einem gummielastischen Werkstoff mit, im Querschnitt der Ankerschiene 2 betrachtet, einander gegenüberliegenden Rastelementen 6, welche die Ankerschiene 2 im Bereich des Ankerschienenschlitzes 3 hintergreifen, eingerastet. Ein pneumatisches Hebeelement 4, hier nur teilweise ersichtlich, ist auf das Betonbauteil in einem die Ankerschiene enthaltenden Teilbereich aufgesetzt. In dem durch das pneumatische Hebeelement 4 und das Betonbauteil 1 gebildeten abgeschlossenen Volumen ist ein Unterdruck erzeugt ("p<0").In the FIG. 1 one recognizes a concrete component 1 with integrated in the concrete component 1 and in cross-section substantially C-shaped anchor rail 2 with a pointing to the outside of the concrete component 1 anchor rail slot 3. In the anchor rail 2 is a preferably closed filling 5 made of a rubber-elastic material with, in cross section of the Anchor rail 2 considered, locking elements 6 opposite one another, which engage behind the anchor rail 2 in the region of the anchor rail slot 3, locked. A pneumatic lifting element 4, only partially visible here, is placed on the concrete component in a part containing the anchor rail portion. In the closed volume formed by the pneumatic lifting element 4 and the concrete component 1, a negative pressure is created ("p <0").

In dem Status der Figur 1 läßt sich durch Betätigung des pneumatischen Hebeelements 4 mit daran angesaugtem Betonbauteil 1 das Betonbauteil 1 anheben und an einen Zielort und in eine Zielposition bewegen. Ist dieser Bewegungsvorgang abgeschlossen, so wird der Unterdruck in dem abgeschlossenen Volumen soweit abgeschwächt, bis das Betonbauteil 1 und das pneumatische Hebeelement 4 voneinander trennbar sind. Das Füllelement 5 kann dann aus der Ankerschiene 2 zumindest teilweise entfernt werden.In the status of FIG. 1 can be lifted by actuation of the pneumatic lifting element 4 with it sucked concrete component 1, the concrete component 1 and move to a destination and in a target position. If this movement process is completed, the negative pressure in the closed volume is weakened until the concrete component 1 and the pneumatic lifting element 4 are separable from one another. The filling element 5 can then be at least partially removed from the anchor rail 2.

Der Figur 1 ist weiterhin zu entnehmen, dass das Füllelement 5 ein Sockelteil 7, ein Stützteil 8 und zwei Rastelemente 6 umfasst. Das Füllelement 5 ist aus einem gummielastischen Werkstoff, im Ausführungsbeispiel einem Silikongummi, gebildet. Die Härte dieses gummielastischen Werkstoffes liegt typischerweise im Bereich von 4 bis 80 Shore A.Of the FIG. 1 It can also be seen that the filling element 5 comprises a base part 7, a support part 8 and two latching elements 6. The filling element 5 is made of a rubber-elastic material, in the exemplary embodiment of a silicone rubber formed. The hardness of this rubber-elastic material is typically in the range of 4 to 80 Shore A.

In der Figur 2 erkennt man, das Füllelement 5 (in der eingebauten Lage) eine Länge aufweist, welche der Länge der Ankerschiene 2 entspricht. Hierdurch ist der Ankerschienenschlitz 3 vollständig zur Oberfläche des Betonbauteils 1 hin abgedichtet.In the FIG. 2 it can be seen, the filling element 5 (in the installed position) has a length which corresponds to the length of the anchor rail 2. This is the Anchor rail slot 3 completely sealed to the surface of the concrete component 1 out.

Wird das Füllelement nur abschnittsweise dort eingesetzt, wo die Dichtung des pneumatischen Hebeelements ansetzt, müssen die Querschnittsteile, die nach Einbringen des eigentlichen Füllelements weiterhin offen sind, mittels zusätzlicher Füllelemente o. ä. geschlossen werden.If the filling element is used only in sections where the seal of the pneumatic lifting element attaches, the cross-sectional parts, which are still open after introduction of the actual filling element, must be closed by means of additional filling elements or the like.

In der Betrachtung der Figur 1 wiederum wird ersichtlich, dass - in dieser Querschnittsdarstellung - die Höhe des Sockelteils 7 bis zu den Rastelementen 6 der Schlitztiefe S des Ankerschienenschlitzes 3 entspricht. Die Gesamthöhe des Füllelements 5 entspricht der Gesamtschlitztiefe T. Weiterhin ist zu entnehmen, dass - in dem dargestellten Querschnitt betrachtet - das Stützteil 8 eine Trapezform aufweist, wobei die Breite des dem Sockelteil gegenüberliegenden Endes des Stützteils kleiner als die Schlitzbreite B der Ankerschiene 2 ist.In the consideration of FIG. 1 In turn, it can be seen that - in this cross-sectional representation - the height of the base part 7 corresponds to the locking elements 6 of the slot depth S of the anchor rail slot 3. The total height of the filling element 5 corresponds to the total slot depth T. Furthermore, it can be seen that - viewed in the cross section shown - the support member 8 has a trapezoidal shape, wherein the width of the base part of the opposite end of the support member is smaller than the slot width B of the anchor rail 2.
