Definitions
- the invention relates to a wedge element, a spacer with at least one such wedge element, a positioning device with such a spacer and a method for positioning wall formwork according to the respective independent claim.
- the wall formwork is arranged in such a way that concrete can be poured in between.
- the wall formwork is positioned in the run-up to the casting process in such a way that the thickness of the wall to be created corresponds as precisely as possible to the specifications.
- the Swiss patents CH687471 and CH651882 from Mägert Bautechnik AG and the Swiss patent application 0781/15 from Mägert & Co. Innovation disclose methods and devices for positioning wall formwork.
- the devices include plastic parts that are used as stop elements for the wall formwork. These are attached to the ends of a spacer rod (round bar). Their outer surface facing the wall formwork to be used serves as a reference for the intended position of the wall formwork.
- the devices for positioning wall formwork are used in the manner described below.
- the floor on which the walls are to be constructed consists of reinforced concrete, the so-called reinforcing bars or reinforcing bars projecting upwards substantially vertically from the floor during the construction phase.
- the positioning devices described above are attached to these reinforcing bars.
- the spacer rod with attached stop elements hereinafter referred to as spacers, is positioned on the reinforcement rod by means of a profile and then fastened so that it cannot slip and thereby falsifies the intended position of the wall to be built.
- a wedge is driven between the reinforcement bar and the spacer bar to attach the spacer to the reinforcement bar.
- a disadvantage of positioning devices in which a wedge is driven between the reinforcement bar and the spacer bar is that the wedge is supplied loose with the spacer bar and can be lost, or the wedge is connected to the spacer bar but is no longer inserted manually between the reinforcement bar and the spacer bar can.
- the object of the invention is therefore to find a solution to the disadvantages mentioned above.
- the object is achieved with a wedge element, a spacer with such a wedge element, a positioning device with such a spacer and a method for positioning and fixing the positioning device.
- a first aspect of the invention relates to a wedge element with a displaceable fastening device for fastening the wedge element to a positioning device for positioning wall formwork when creating a concrete part.
- the wedge element is designed to fix the positioning device to a reinforcing bar of the concrete part and comprises a wedge-shaped main body with a first and a second active surface which effects a wedge effect.
- the wedge element can be fastened to a spacer rod of the positioning device by means of the fastening device, so that the first active surface faces the spacer rod.
- the fastening device is arranged on the first active surface of the main body and connected to it in such a way that the main body can be displaced with respect to the fastening device essentially in the direction of the wedge effect of the wedge element and in the opposite direction.
- a second aspect of the invention is concerned with a spacer, comprising a spacer rod which has a stop element at least at one of its ends, preferably a stop element at both ends.
- the spacer further comprises at least one wedge element according to the first aspect of the invention.
- the wedge element is fastened to the spacer rod by means of its fastening device in such a way that it can be freely moved along the spacer rod.
- a positioning device for positioning wall formwork when creating a reinforced concrete part.
- the positioning device comprises a spacer according to the second aspect of the invention and a profile with a guide section for receiving a reinforcing bar of the reinforced concrete part and a holding section with openings for receiving the spacer bar of the spacer.
- the profile is designed such that the reinforcing bar between the spacer bar and the guide section can be accommodated in the profile, such that the spacer rod can be moved back and forth in the fastening device and the openings of the profile in order to set an intended position of the positioning device and is fixed in the intended position by means of the wedge element of the spacer on the reinforcing rod.
- the positioning device according to the third aspect of the invention is preferably used as a stop or spacer in concrete, or wood, or metal construction when positioning provisional parts.
- the positioning device in concrete construction is particularly preferred when positioning wall formwork to form concrete structures (eg concrete walls).
- an advantage of the invention is that the wedge element according to the first aspect of the invention can be attached to the spacer rod by means of its fastening device, so that it can no longer be lost.
- the spacer according to the second aspect of the invention can be supplied with a wedge element already fastened, which simplifies the work when creating concrete walls.
- the wedge element can also be supplied individually and serve to equip existing spacers which do not yet benefit from the invention, in order to then simplify the work.
- Another advantage results from the fact that the main body of the wedge element can be displaced in the direction of the wedge effect and in the opposite direction relative to the fastening device. This makes it possible to pre-fix the wedge element manually and only then using e.g. a hammer to the end position. Pre-fixing the wedge element is desirable for several reasons. The most important thing is the security aspect; without the possibility of pre-fixing, the operator must hold the wedge element with one hand and use the hammer to drive it in with the other hand. This can lead to injuries and should therefore be avoided.
- the wedge element is already in the gap between the reinforcing bar and the spacer bar, in other words, the wedge element is thereby pretensioned or pre-fixed so that it no longer has to be held when the hammer is finally driven in and the risk described above is eliminated.
- insert refers to a force acting on the wedge element, which is of the order of magnitude of a force that can be applied by a person.
- driving in refers to a force exerted on the wedge element with a hammer or a comparable tool, which is many times higher than the force during insertion.
- Fig. 1 shows a schematic perspective view of a construction section for building a wall 10 on a reinforced concrete part 12 and Fig. 2 a perspective side view of the construction section Fig. 1 .
- the figures show a positioning device 8 according to the invention which is fastened to a reinforcing bar 9 of the concrete part 12.
- several positioning devices 8 are typically used to ensure that the wall 10 to be built is correctly positioned over the entire length.
- a wall is chosen as an illustrative example of a partial building, but the invention can also be used for the construction of other partial buildings.

- Wall formwork 11 are attached to both sides of the walls 10 and serve to shape the wall 10 when pouring the concrete.
- the term “intended position” in connection with any element of the devices according to the invention is to be understood as that position of the element which is used to achieve correct positioning of the wall 10.
- the intended position of the profile 5 is on the concrete part 12.
- the profile 5 could also be fastened further up along the reinforcing bar 9, the position on the floor has the advantage that the reinforcing bar 9 is opposite in this area lateral bending is most insensitive and therefore the fastening of the positioning device 8 at this point results in the most precise determination of the position of the wall 10.
- the wedge element 1 can be individually retrofitted to existing construction sites in one application. In a further use case, it can be supplied as part of the spacer 7 mentioned above. Again, a spacer 7 according to the invention can also be part of the positioning device in a further use 8, which corresponds to a complete solution that can be used immediately for attachment to reinforcing bars 9.

Die Schweizerischen Patente
Die Vorrichtungen zur Positionierung von Wandschalungen werden in der nachfolgend beschriebenen Weise verwendet. Typischerweise besteht der Boden, auf dem die Wände errichtet werden sollen, aus armiertem Beton, dessen sogenannten Armierungseisen oder Armierungsstäbe in der Bauphase nach oben im Wesentlichen senkrecht aus dem Boden ragen. An diesen Armierungsstäben werden die oben beschriebenen Positionierungsvorrichtungen angebracht. Der Distanzhalterstab mit daran angebrachten Anschlagelementen, im Folgenden Abstandhalter genannt, wird mittels eines Profils am Armierungsstab positioniert und anschliessend befestigt, so dass es nicht verrutschen kann und dadurch die bestimmungsgemässe Lage der zu bauenden Wand verfälscht. Zur Befestigung des Abstandhalters am Armierungsstab wird ein Keil zwischen dem Armierungsstab und dem Distanzhalterstab getrieben.The devices for positioning wall formwork are used in the manner described below. Typically, the floor on which the walls are to be constructed consists of reinforced concrete, the so-called reinforcing bars or reinforcing bars projecting upwards substantially vertically from the floor during the construction phase. The positioning devices described above are attached to these reinforcing bars. The spacer rod with attached stop elements, hereinafter referred to as spacers, is positioned on the reinforcement rod by means of a profile and then fastened so that it cannot slip and thereby falsifies the intended position of the wall to be built. A wedge is driven between the reinforcement bar and the spacer bar to attach the spacer to the reinforcement bar.
Ein Nachteil von Positioniervorrichtungen bei welchen ein Keil zwischen Armierungsstab und Distanzhalterstab eingetrieben wird ist, dass der Keil lose zum Distanzhalterstab mitgeliefert wird und so verloren gehen kann, oder der Keil zwar verbunden mit dem Distanzhalterstab vorliegt aber nicht mehr von Hand zwischen Armierungsstab und Distanzhalterstab eingesteckt werden kann.A disadvantage of positioning devices in which a wedge is driven between the reinforcement bar and the spacer bar is that the wedge is supplied loose with the spacer bar and can be lost, or the wedge is connected to the spacer bar but is no longer inserted manually between the reinforcement bar and the spacer bar can.

The fastening device is arranged on the first active surface of the main body and connected to it in such a way that the main body can be displaced with respect to the fastening device essentially in the direction of the wedge effect of the wedge element and in the opposite direction.
Ein zweiter Aspekt der Erfindung befasst sich mit einem Abstandhalter, umfassend einen Distanzhalterstab der mindestens an einem seiner Enden ein Anschlagelement, vorzugsweise an beiden Enden jeweils ein Anschlagelement aufweist. Der Abstandhalter umfasst weiter mindestens ein Keilelement gemäss dem ersten Aspekt der Erfindung. Das Keilelement ist mittels seiner Befestigungsvorrichtung am Distanzhalterstab derart befestigt, dass es frei entlang des Distanzhalterstabs verschiebbar ist.A second aspect of the invention is concerned with a spacer, comprising a spacer rod which has a stop element at least at one of its ends, preferably a stop element at both ends. The spacer further comprises at least one wedge element according to the first aspect of the invention. The wedge element is fastened to the spacer rod by means of its fastening device in such a way that it can be freely moved along the spacer rod.
In einem dritten Aspekt der Erfindung wird eine Positioniervorrichtung zur Positionierung von Wandschalungen beim Erstellen eines armierten Betonteils beansprucht. Die Positioniervorrichtung umfasst einen Abstandhalter gemäss dem zweiten Aspekt der Erfindung und ein Profil mit einem Führungsabschnitt zur Aufnahme eines Armierungsstabs des armierten Betonteils und einem Halteabschnitt mit Öffnungen zur Aufnahme des Distanzhalterstabs des Abstandhalters. Das Profil ist derart ausgestaltet, dass der Armierungsstab zwischen dem Distanzhalterstab und dem Führungsabschnitt im Profil aufnehmbar ist, derart dass zur Einstellung einer bestimmungsgemässen Position der Positioniervorrichtung der Distanzhalterstab in der Befestigungsvorrichtung und den Öffnungen des Profils hin und her verschiebbar ist und in der bestimmungsgemässen Position mittels des Keilelements des Abstandhalters am Armierungsstab fixiert ist.In a third aspect of the invention, a positioning device for positioning wall formwork when creating a reinforced concrete part is claimed. The positioning device comprises a spacer according to the second aspect of the invention and a profile with a guide section for receiving a reinforcing bar of the reinforced concrete part and a holding section with openings for receiving the spacer bar of the spacer. The profile is designed such that the reinforcing bar between the spacer bar and the guide section can be accommodated in the profile, such that the spacer rod can be moved back and forth in the fastening device and the openings of the profile in order to set an intended position of the positioning device and is fixed in the intended position by means of the wedge element of the spacer on the reinforcing rod.
Ein vierter Aspekt der Erfindung betrifft ein Verfahren zur Fixierung einer Positioniervorrichtung an einem Armierungsstab eines armierten Betonteils. Das Verfahren umfasst die folgenden Schritte:
- a) Positionieren des Profils am Armierungsstab,
- b) Einbringen des Distanzhalterstabs des Abstandhalters an oder in den Halteabschnitt des Profils, entweder vor oder nach a),
- c) Positionieren des im Halteabschnitt des Profils angeordneten Distanzhalterstabs derart, dass die Anschlagelemente der Positioniervorrichtung in bestimmungsgemässer Lage angeordnet sind,
- d) Vorfixieren der Positioniervorrichtung am Armierungsstab indem der Hauptkörper des Keilelement zwischen Distanzhalterstab und Armierungsstab eingeschoben wird, wobei sich der Hauptkörper beim Einschieben bezogen auf die Befestigungsvorrichtung des Keilelements verschiebt, wobei der Hauptkörper solange eingeschoben wird bis das Keilelement ohne weitere fremde Einwirkung stecken bleibt,
- e) Endgültiges Fixieren der Positioniervorrichtung am Armierungsstab indem das eingeschobene Keilelement mittels eines Werkzeugs weiter zwischen Distanzhalterstab und Armierungsstab eingetrieben wird.
- a) positioning the profile on the reinforcing bar,
- b) inserting the spacer rod of the spacer onto or into the holding section of the profile, either before or after a),
- c) positioning the spacer rod arranged in the holding section of the profile in such a way that the stop elements of the positioning device are arranged in the correct position,
- d) pre-fixing the positioning device on the reinforcement rod by inserting the main body of the wedge element between the spacer rod and the reinforcement rod, the main body being displaced relative to the fastening device of the wedge element when being pushed in, the main body being pushed in until the wedge element remains stuck without further external action
- e) Final fixing of the positioning device on the reinforcement rod by the inserted wedge element being driven in between a spacer rod and reinforcement rod using a tool.
Die Positioniervorrichtung gemäss dem dritten Aspekt der Erfindung wird vorzugsweise als Anschlag- oder Distanzhalterung im Beton-, oder Holz-, oder Metallbau bei der Positionierung von provisorischen Teilen verwendet. Besonders bevorzugt kommt die Positioniervorrichtung im Betonbau bei der Positionierung von Wandschalungen zur Bildung von Betonstrukturen (z.B. Betonwänden).The positioning device according to the third aspect of the invention is preferably used as a stop or spacer in concrete, or wood, or metal construction when positioning provisional parts. The positioning device in concrete construction is particularly preferred when positioning wall formwork to form concrete structures (eg concrete walls).
Ein Vorteil der Erfindung ist, dass das Keilelement gemäss dem ersten Aspekt der Erfindung mittels seiner Befestigungsvorrichtung am Distanzhalterstab angebracht werden kann, so dass er nicht mehr verloren gehen kann. Vorteilhafterweise kann der Abstandhalter nach dem zweiten Aspekt der Erfindung mit bereits befestigtem Keilelement geliefert werden, was die Arbeit bei der Erstellung von Betonwänden vereinfacht. Das Keilelement kann aber auch einzeln geliefert werden und dazu dienen, bereits vorhandene Abstandhalter, die noch nicht von der Erfindung profitieren, damit auszurüsten, um anschliessend die Arbeit zu vereinfachen.An advantage of the invention is that the wedge element according to the first aspect of the invention can be attached to the spacer rod by means of its fastening device, so that it can no longer be lost. Advantageously, the spacer according to the second aspect of the invention can be supplied with a wedge element already fastened, which simplifies the work when creating concrete walls. However, the wedge element can also be supplied individually and serve to equip existing spacers which do not yet benefit from the invention, in order to then simplify the work.
Ein weiterer Vorteil ergibt sich dadurch, dass der Hauptkörper des Keilelements bezogen auf die Befestigungsvorrichtung in Richtung der Keilwirkung und in entgegengesetzter Richtung verschiebbar ist. Dadurch ist es möglich, das Keilelement manuell vorzufixieren und erst dann mittels z.B. eines Hammers bis zur Endstellung einzutreiben. Eine Vorfixierung des Keilelements ist aus mehreren Gründen wünschenswert. Am wichtigsten dabei ist der Sicherheitsaspekt; ohne Vorfixierungsmöglichkeit muss die bedienende Person das Keilelement mit einer Hand festhalten und mit der anderen Hand den Hammer zum Eintreiben betätigen. Dies kann zu Verletzungen führen und ist deshalb zu vermeiden. Bei einer Vorfixierung steckt das Keilelement schon in der Spalte zwischen Armierungsstab und Distanzhalterstab, mit anderen Worten ist das Keilelement dadurch vorgespannt oder vorfixiert, so dass es beim endgültigen Eintreiben mit dem Hammer nicht mehr gehalten werden muss und die oben beschriebene Gefahr ausgeräumt ist.Another advantage results from the fact that the main body of the wedge element can be displaced in the direction of the wedge effect and in the opposite direction relative to the fastening device. This makes it possible to pre-fix the wedge element manually and only then using e.g. a hammer to the end position. Pre-fixing the wedge element is desirable for several reasons. The most important thing is the security aspect; without the possibility of pre-fixing, the operator must hold the wedge element with one hand and use the hammer to drive it in with the other hand. This can lead to injuries and should therefore be avoided. In the case of a pre-fixation, the wedge element is already in the gap between the reinforcing bar and the spacer bar, in other words, the wedge element is thereby pretensioned or pre-fixed so that it no longer has to be held when the hammer is finally driven in and the risk described above is eliminated.

In diesem Zusammenhang wird angemerkt dass für den gesamten Text dieses Dokuments der Begriff "bestimmungsgemässe Position" in Zusammenhang mit jeglichem Element der erfindungsgemässen Vorrichtungen als diejenige Position des Elements verstanden wird, welche zum Erreichen einer korrekten Positionierung der Wand 10 Beispielsweise ist die bestimmungsgemässe Position des Anschlagelements 6a direkt an der Wandschalung 11. Die bestimmungsgemässe Position des Profils 5 ist auf dem Betonteil 12. Obwohl das Profil 5 auch weiter oben entlang des Armierungsstabs 9 befestigt werden könnte, hat die Lage am Boden den Vorteil, dass der Armierungsstab 9 in diesem Bereich gegenüber seitlicher Biegung am unempfindlichsten ist und daher die Befestigung der Positioniervorrichtung 8 an dieser Stelle in der exaktesten Festlegung der Lage der Wand 10 resultiert.In this context, it is noted that for the entire text of this document, the term “intended position” in connection with any element of the devices according to the invention is to be understood as that position of the element which is used to achieve correct positioning of the
Das Keilelement 1 kann in einem Verwendungsfall einzeln bei bereits vorhandenen Baustellen nachgerüstet werden. In einem weiteren Verwendungsfall kann es als Teil des oben genannten Abstandhalters 7 geliefert werden.

In einer weiteren Ausführungsform (nicht gezeigt) ist das Halteelement elastisch und im Wesentlichen plattenförmig. Es ist an seiner Unterseite beabstandet von der ersten Wirkfläche am Hauptkörper befestigt, so dass der Distanzhalterstab im Zwischenraum zwischen der Platte und der Wirkfläche einführbar ist. Das Bindeglied ist mindestens ein Klemmelement das an einem Ende im oberen Bereich des Halteelements mit diesem fest verbunden ist und am anderen Ende an einer oberen Ecke der zweiten Wirkfläche derart eingehackt ist, dass es eine Verschiebung des oberen Bereichs des elastischen Halteelements in Richtung der ersten Wirkfläche und zurück erlaubt. Alternativ kann das Bindeglied mindestens ein mit dem Hauptkörper fest verbundenes Band umfassen, das elastisch biegbar ist.In a further embodiment (not shown), the holding element is elastic and essentially plate-shaped. It is attached to the main body on its underside at a distance from the first active surface, so that the spacer rod can be inserted in the space between the plate and the active surface. The link is at least one clamping element which is firmly connected to the holding element at one end in the upper region thereof and is hooked at the other end to an upper corner of the second active surface in such a way that it displaces the upper region of the elastic holding element in the direction of the first active surface and allowed back. Alternatively, the connecting link can comprise at least one band which is fixedly connected to the main body and which is elastically bendable.

Bei der Verwendung eines Keilelements nach
Der Vorteil der vorliegenden Erfindung ist einerseits dass das Keilelement mit einer Befestigungsvorrichtung ausgestattet ist, die eine Befestigung am Distanzhalterstab erlaubt, so dass das Keilelement nicht verloren gehen kann. Andererseits erlaubt die Verschiebbarkeit des Hauptkörpers des Keilelements bezüglich der Befestigungsvorrichtung eine Vorfixierung des Keilelements ohne dass dieses für den Schritt der endgültigen Fixierung noch wie bei bekannten Lösungen manuell gehalten werden muss. Damit werden schwere Handverletzungen aufgrund der hohen aufzuwendenden Kraft beim Eintreiben verhindert. Nicht zuletzt gestaltet sich der Arbeitsschritt des Eintreibens für die Person komfortabler, da sie nicht beide Hände benutzen muss.The advantage of the present invention is, on the one hand, that the wedge element is equipped with a fastening device which permits fastening to the spacer rod, so that the wedge element cannot be lost. On the other hand, the displaceability of the main body of the wedge element with respect to the fastening device allows the wedge element to be pre-fixed without having to manually hold it for the step of final fixing, as in known solutions. This prevents serious hand injuries due to the high force required when driving in. Last but not least, the driving in step is more comfortable for the person, since they do not have to use both hands.
Obwohl bevorzugte Ausführungsformen der Erfindung beschrieben worden sind wird darauf hingewiesen, dass die Erfindung auf anderen Weisen im Rahmen der nachfolgenden Ansprüchen realisiert werden kann. Dabei beziehen sich in der Beschreibung verwendete Begriffe wie "bevorzugt", "insbesondere", "vorteilhaft", etc. nur auf optionale und beispielhafte Ausführungsformen.Although preferred embodiments of the invention have been described, it is pointed out that the invention can be implemented in other ways within the scope of the following claims. Terms used in the description such as “preferred”, “in particular”, “advantageous”, etc. only relate to optional and exemplary embodiments.
