Definitions
- the invention further relates to a shear force anchor and a battery formwork with such a formwork device and a component that can be produced with the battery formwork.
- the invention also relates to a method for producing such a component and a method for supporting a finished component.
- transport anchors can be used for lifting heavy concrete components such as precast concrete parts and the like, which are concreted into the concrete component in question.
- the known transport anchors can have threaded sleeves into which crane loops or the like are screwed for lifting or transport purposes.
- the transport anchor can have a transverse force part which extends transversely to the longitudinal axis of the threaded sleeve, that is, in the direction of the thickness of the precast concrete part. Precise positioning of the lifting anchor in the precast concrete part is required to ensure effective dissipation of the longitudinal and transverse forces. It would also be desirable to expand the functionality of the lifting anchor.
- the present invention has the task of alleviating or eliminating at least individual disadvantages of the prior art.
- the aim of the invention is, in particular, to improve the insertion of the transport anchor during the manufacture of the component and / or to develop further functions with the transport anchor.
- the transport anchor has a first connecting element for connecting the transport anchor to the formwork element and / or a second connecting element for connecting the transport anchor to a support element for supporting the component.
- the transport anchor can thus fulfill various functions.
- the connection part of the lifting anchor is used to attach a lifting device, preferably to a front or narrow side of the finished component.
- the component can be lifted out of the formwork and placed on the ground.
- the component can be lifted from the ground using the lifting device.
- the lifting device can, for example, have a lifting device, in particular with a chain.
- the transverse force part introduces transverse forces, that is to say forces transverse to the main extension plane of the component, into the component. A failure of the component can advantageously be delayed or prevented in this way.
- the transverse force part has at least one load transfer surface which is spaced from the outside of the connection part in the direction of the transverse force to be derived, ie in the thickness direction of the component, to the outside, ie to one of the longitudinal sides of the component.
- two load transfer surfaces are provided for the transfer of transverse forces into the component, which in the transverse direction are spaced from each other.
- the load transfer surfaces are preferably arranged symmetrically with respect to a center plane of the component. The transverse forces are introduced via the connection part and diverted into the component via the transverse force part rigidly connected to it.
- the transport anchor takes on at least one other function.
- the transport anchor preferably on the transverse force part, has a first connecting element which is reversibly detachably connected to the formwork element.
- the transport anchor In the connected state, the transport anchor is arranged immovably on the formwork element in a defined assembly position.
- the first connecting element of the lifting anchor can be brought into engagement with a corresponding connecting element on the formwork element before the component is cast.
- precise positioning of the transport anchor in the component is achieved and thus the effective dissipation of the transverse forces when handling the component with the lifting device is ensured.
- the component is fixed to the formwork element via the transport anchor. This significantly increases the safety when stripping.
- the transport anchor has a second connecting element, in particular on the side facing away from the formwork element.
- the second connecting element can be connected to a support element, for example a set-up support, in order to achieve reliable and simple support of the component, in particular on the floor.
- the support element can in particular be used to support the component in a vertical state, preferably when assembling several components to form a structure, for example a house.
- the transport anchor therefore offers a simple and stable connection point for the support element, which therefore does not have to be attached to the concrete body.
- the transport anchor In the assembled state on the formwork device, the transport anchor is in this way in the formwork space between the formwork element and a further formwork element is arranged so that the first connecting element extends at least to the front of the formwork element for the application of concrete.
- the first connecting element preferably engages in the formwork element in the assembled state.
- the second connecting element extends as far as the opposite further formwork element, so that the second connecting element is freely accessible on the corresponding longitudinal side of the component in the concreted state.
- the location and direction details relate to the concreting position of the formwork device with the formwork element preferably being oriented essentially vertically in order to pour the component with the aid of the formwork device.
- the first connection element of the transport anchor has a first threaded part, in particular a threaded bolt, which is connected to a second threaded part on the formwork element, in particular a nut.
- a screw connection can thus be provided between the transport anchor and the formwork element.
- another connection for example a latching connection, can also be provided.
- the transverse force part has a through opening for the arrangement of the first connecting element from the side of the transverse force part facing away from the formwork element.
- the through opening preferably extends from the end facing away from the formwork element to the end of the transverse force part facing the formwork element.
- the transport anchor is preferably made of metal or plastic, in particular fiber-reinforced plastic, or a connection therefrom.
- the transport anchor preferably has an anchor bolt, in particular with an undercut, which in the concreted-in state preferably essentially extends along the main plane of the structural element (i.e. in the case of a plate-shaped precast concrete part parallel to the two long sides, which are connected to one another via, in comparison, narrower end faces).
- the second connection element can be a threaded element, in particular with an internal thread.
- the support element can thus be connected to the threaded element via a screw connection.
- connection part has a connection sleeve, in particular with an internal thread, which extends as far as an end face of the component, based on the concreted state of the component.
- the lifting device with which the component can be handled can be attached to the connecting sleeve.
- the longitudinal axis of the connecting sleeve preferably runs essentially parallel to the main plane of extent of the component, in particular essentially perpendicular to the end face at which the connecting sleeve opens.
- the transverse force part has a transverse force sleeve, a first widening being provided at the first end of the transverse force sleeve and / or a second widening being provided at the second end of the transverse force sleeve.
- first or second widening in particular over the inside thereof, a particularly effective dissipation of the transverse forces can be achieved.
- the first and / or second widening can be designed as a disk or plate, with on the inside the first or second widening, the load transfer surface can be formed. A particularly large breakout cone is thus achieved.
- a protective cap is detachably arranged on the first and / or second widening of the transverse force part.
- Such a "butterfly formwork" is for example from the WO 2016/184947 A1 known.
- the two preferably rectangular formwork elements are each pivotably connected at a first end region, in particular on one of their longitudinal sides. For this purpose, an articulated connection can be provided between the first end regions of the formwork elements.
- the two formwork elements can be transferred from a standing state, in which the formwork elements are preferably aligned essentially vertically, to a lying state, in which the formwork elements are preferably aligned essentially horizontally.
- the first end areas form the upper ends of the formwork elements and the second end areas form the lower ends of the formwork elements.
- the formwork elements can be arranged in the standing state between the two bulkheads of the battery formwork.
- the formwork elements are in the folded-up state (that is, they are essentially parallel to one another), with the formwork fronts pointing outwards and the formwork backs facing each other.
- the two front sides of the formwork delimit cavities into which concrete can be poured.
- the lying state of the formwork elements can be used to attach formwork elements, that is to say in particular delimitation elements for door and / or window cutouts in the component, to the formwork front sides of the formwork elements.
- a battery formwork can be used to cast the component, in which a formwork space between the formwork element the formwork device described above and a further formwork element is formed.
- the further formwork element can be a single formwork panel.
- two further formwork elements can be pivotably connected to one another at their first end regions, as was explained above in connection with the formwork device.
- the formwork space is formed between the formwork device and one of the further formwork elements.
- a battery formwork can be expanded as required by formwork devices and further formwork elements in order to form several formwork spaces for the production of several components.
- the transverse force part of the formwork device extends from the outside (front side) of the formwork element through the formwork space to the facing outside of the further formwork element.
- This embodiment is particularly favorable because a through-support between the formwork device and the further formwork element is achieved. In this way, bending of the formwork elements due to the concrete pressure, in particular in the upper areas of the formwork elements, can be reliably prevented.
- the formwork device described above can be used to produce a structural element which is preferably a plate-shaped precast concrete part.
- the component has a hardened concrete body in which the transport anchor is cast.
- the transport anchor is therefore not subsequently introduced into the finished component (like a dowel or the like), but rather is arranged in the formwork space before the component is poured.
- the transport anchor is therefore designed as an insert.
- the transverse force part extends in the thickness direction of the concrete body from one longitudinal side to the other longitudinal side of the concrete body, which is preferably designed as a plate.
- Fig. 1 shows a schematic representation of an example from FIG WO 2017/174432 known battery formwork 1 with formwork devices 2.

- a cavity to be filled with concrete is formed between at least one bulkhead 6 and a shuttering device 2, the shuttering device 2 preferably carrying shuttering elements (not shown) that determine the contour of the precast concrete part.
- the formwork elements can, for example, delimit door or window cutouts and also seal the cavity filled with concrete during concreting.
- the formwork elements can be attached to the formwork device 2 with magnetic holders, for example.
- a heating device (not shown) and / or a vibrator (not shown) can also be mounted on the formwork device 2.
- the formwork device 2 is used between two bulkheads 6 and braced with them during concreting.
- the number of support devices 5 of the bulkheads 6 and the formwork devices 2 is to be regarded as only exemplary and can be varied depending on the circumstances.
- formwork devices 2 can be provided for concreting the outer walls, inner walls, the floor and the roof of a house, so that the components for an entire building can be produced simultaneously with the battery formwork 1.
- the bulkheads 6 and the formwork devices 2 are clamped between two support devices 7.
- the number of support devices 7 is also to be regarded as only exemplary and can be used as required can be varied.
- At least one support device 7 is movably, ie displaceably in the present embodiment, received in the support devices 5.
- the formwork devices 2 and the support devices 7 can be connected to one another and braced in the concreting position by one or more rod-shaped connecting devices 8.
- the number of connecting devices 8 can be adapted to the circumstances. Instead of rod-shaped connecting devices 8, hydraulic connecting devices are also possible.
- the rod-shaped connecting devices 8 are, however, particularly robust and easy to handle.
- the battery formwork 1 has a lifting device 9 with which at least one of the formwork devices 2 can be transferred from the lowered concreting position to a raised transport position, in which the formwork device 2 can be conveyed in a direction essentially perpendicular to the lifting direction via a formwork device 2 in the concreting position is.
- the formwork devices 2 are hooked into the support devices 5 from above, so that in the hooked-in state in the concreting position they are spaced from the ground between the support sections 4.
- the design of the lifting device 9 can be adapted to the requirements. If necessary, several lifting devices 9 can also be used.
- the lifting device 9 can be moved in a tensioning direction of the formwork devices 2 on two guide devices 10 which are spaced apart from one another and which are designed here as running rails. Furthermore, the guide devices 10 are arranged above the support devices 5 and parallel to them. In order to make the battery formwork 1 more compact, the formwork devices 2 are attached to the support devices 5 at their upper end.
- the formwork devices 2 according to the invention can be accommodated in the battery formwork 1, which are shown below with reference to FIG Figures 2 to 4 explained.
- Fig. 2 shows several formwork equipment 2, which in particular for the arrangement between two bulkheads 6 of the battery mold 1 according to Fig. 1 are set up.
- the formwork device 2 has two formwork elements 11 which, in the embodiment shown, are formwork panels.
- the formwork elements 11 each have a formwork front side 12 for the application of concrete and a formwork rear side 13.

Bei der Handhabung großformatiger Betonplatten treten jedoch zudem erhebliche Querkräfte auf, insbesondere beim Umlegen der Betonfertigteile von einem hochkant stehenden Zustand in einen liegenden Zustand auf einem Untergrund. Um die Querkräfte in das Betonfertigteil abzuleiten, kann der Transportanker ein Querkraftteil aufweisen, welches quer zur Längsachse der Gewindehülse, also in Dickenrichtung des Betonfertigteils, erstreckt ist. Um eine wirksame Ableitung der Längs- und Querkräfte zu gewährleisten, ist eine präzise Positionierung des Transportankers im Betonfertigteil erforderlich. Weiters wäre es wünschenswert, den Funktionsumfang des Transportankers zu erweitern.When concreted in, the precast concrete elements are subjected to tensile forces from the hoist. When handling large-format concrete slabs, however, there are also considerable transverse forces, in particular when the precast concrete parts are turned over from an upright position to a lying position on a substrate. In order to divert the transverse forces into the precast concrete part, the transport anchor can have a transverse force part which extends transversely to the longitudinal axis of the threaded sleeve, that is, in the direction of the thickness of the precast concrete part. Precise positioning of the lifting anchor in the precast concrete part is required to ensure effective dissipation of the longitudinal and transverse forces. It would also be desirable to expand the functionality of the lifting anchor.
Demnach stellt sich die vorliegende Erfindung der Aufgabe, zumindest einzelne Nachteile des Standes der Technik zu lindern bzw. zu beheben. Die Erfindung hat insbesondere zum Ziel das Einlegen des Transportankers beim Herstellen des Bauelements zu verbessern und/oder weitere Funktionen mit dem Transportanker zu erschließen.Accordingly, the present invention has the task of alleviating or eliminating at least individual disadvantages of the prior art. The aim of the invention is, in particular, to improve the insertion of the transport anchor during the manufacture of the component and / or to develop further functions with the transport anchor.
Diese Aufgabe wird mit einer Schalungseinrichtung nach Anspruch 1, einen Querkraftanker nach Anspruch 9, eine Batterieschalung nach Anspruch 10, ein Bauelement nach Anspruch 12, ein Verfahren zum Herstellen eines solchen Bauelements nach Anspruch 14 und ein Verfahren zum Abstützen eines fertigen Bauelements nach Anspruch 15 gelöst. In den abhängigen Ansprüchen sind bevorzugte Ausführungsformen angegeben.This object is achieved with a formwork device according to
Erfindungsgemäß weist der Transportanker ein erstes Verbindungselement zur Verbindung des Transportankers mit dem Schalungselement und/oder ein zweites Verbindungselement zur Verbindung des Transportankers mit einem Stützelement für die Abstützung des Bauelements auf.According to the invention, the transport anchor has a first connecting element for connecting the transport anchor to the formwork element and / or a second connecting element for connecting the transport anchor to a support element for supporting the component.
Somit kann der Transportanker verschiedene Funktionen erfüllen. Wie beim Stand der Technik dient das Anschlussteil des Transportankers dazu, eine Hebeeinrichtung vorzugsweise an einer Stirn- bzw. Schmalseite des fertigen Bauelement anzubringen. Mit Hilfe der Hebeeinrichtung kann das Bauelement aus der Schalung herausgehoben und auf dem Untergrund abgelegt werden. Weiters kann das Bauelement über die Hebeeinrichtung vom Untergrund aufgehoben werden. Die Hebeeinrichtung kann beispielsweise ein Hebezeug, insbesondere mit einer Kette, aufweisen. Durch das Querkraftteil werden Querkräfte, also Kräfte quer zur Haupterstreckungsebene des Bauelements, in das Bauelement eingebracht. Vorteilhafterweise kann so ein Versagen des Bauelements verzögert bzw. verhindern werden. Hierfür weist das Querkraftteil zumindest eine Lastübertragungsfläche auf, welche von der Außenseite des Anschlussteils in Richtung der abzuleitenden Querkraft, d.h. in Dickenrichtung des Bauelements, nach außen, d.h. zu einer der Längsseiten des Bauelements hin, beabstandet ist. Vorzugsweise sind zwei Lastübertragungsflächen für die Übertragung von Querkräften in das Bauelement vorgesehen, welche in Querrichtung voneinander beabstandet sind. Die Lastübertragungsflächen sind bevorzugt symmetrisch bezüglich einer Mittelebene des Bauelements angeordnet. Die Querkräfte werden über das Anschlussteil eingeleitet und über das damit starr verbundene Querkraftteil in das Bauelement abgeleitet.The transport anchor can thus fulfill various functions. As in the prior art, the connection part of the lifting anchor is used to attach a lifting device, preferably to a front or narrow side of the finished component. With the help of the lifting device, the component can be lifted out of the formwork and placed on the ground. Furthermore, the component can be lifted from the ground using the lifting device. The lifting device can, for example, have a lifting device, in particular with a chain. The transverse force part introduces transverse forces, that is to say forces transverse to the main extension plane of the component, into the component. A failure of the component can advantageously be delayed or prevented in this way. For this purpose, the transverse force part has at least one load transfer surface which is spaced from the outside of the connection part in the direction of the transverse force to be derived, ie in the thickness direction of the component, to the outside, ie to one of the longitudinal sides of the component. Preferably, two load transfer surfaces are provided for the transfer of transverse forces into the component, which in the transverse direction are spaced from each other. The load transfer surfaces are preferably arranged symmetrically with respect to a center plane of the component. The transverse forces are introduced via the connection part and diverted into the component via the transverse force part rigidly connected to it.
Erfindungsgemäß übernimmt der Transportanker zumindest eine weitere Funktion. In einer ersten Ausführungsform weist der Transportanker, vorzugsweise am Querkraftteil, ein erstes Verbindungselement auf, welches mit dem Schalungselement reversibel lösbar verbunden ist. Im verbundenen Zustand ist der Transportanker in einer definierten Montagestellung unbeweglich an dem Schalungselement angeordnet. Somit kann das erste Verbindungselement des Transportankers vor dem Gießen des Bauelements mit einem entsprechenden Verbindungselement an dem Schalungselement in Eingriff gebracht werden. Dadurch wird eine präzise Positionierung des Transportankers im Bauelement erreicht und so die wirksame Ableitung der Querkräfte bei der Handhabung des Bauelements mit der Hebeeinrichtung sichergestellt. Weiters ist vorteilhaft, dass das Bauelement über den Transportanker an dem Schalungselement fixiert ist. Dadurch wird die Sicherheit beim Ausschalen wesentlich erhöht. Nach dem Lösen der Verbindung zwischen dem Transportanker und dem Schalungselement kann das Bauelement von dem Schalungselement entfernt werden. In einer zweiten Ausführungsform weist der Transportanker ein zweites Verbindungselement insbesondere auf der vom Schalungselement abgewandten Seite auf. Nach der Fertigstellung des Bauelements kann das zweite Verbindungselement mit einem Stützelement, beispielsweise einer Einrichtstütze, verbunden werden, um eine zuverlässige und einfache Abstützung des Bauelements insbesondere am Boden zu erreichen. Das Stützelement kann insbesondere zur Abstützung des Bauelements in einem vertikalen Zustand, vorzugsweise beim Zusammenstellen mehrerer Bauelemente zu einem Bauwerk, beispielsweise einem Haus, genutzt werden. Der Transportanker bietet daher eine einfache und stabile Anschlussstelle für das Abstützelement, welches daher nicht am Betonkörper angebracht werden muss.According to the invention, the transport anchor takes on at least one other function. In a first embodiment, the transport anchor, preferably on the transverse force part, has a first connecting element which is reversibly detachably connected to the formwork element. In the connected state, the transport anchor is arranged immovably on the formwork element in a defined assembly position. Thus, the first connecting element of the lifting anchor can be brought into engagement with a corresponding connecting element on the formwork element before the component is cast. As a result, precise positioning of the transport anchor in the component is achieved and thus the effective dissipation of the transverse forces when handling the component with the lifting device is ensured. It is also advantageous that the component is fixed to the formwork element via the transport anchor. This significantly increases the safety when stripping. After the connection between the transport anchor and the formwork element has been released, the component can be removed from the formwork element. In a second embodiment, the transport anchor has a second connecting element, in particular on the side facing away from the formwork element. After completion of the component, the second connecting element can be connected to a support element, for example a set-up support, in order to achieve reliable and simple support of the component, in particular on the floor. The support element can in particular be used to support the component in a vertical state, preferably when assembling several components to form a structure, for example a house. The transport anchor therefore offers a simple and stable connection point for the support element, which therefore does not have to be attached to the concrete body.
Im montierten Zustand an der Schalungseinrichtung ist der Transportanker derart in dem Schalungsraum zwischen dem Schalungselement und einem weiteren Schalungselement angeordnet, dass das erste Verbindungselement zumindest bis zur Vorderseite des Schalungselements für die Beaufschlagung mit Beton erstreckt ist. Bevorzugt greift das erste Verbindungselement im montierten Zustand in das Schalungselement ein. Das zweite Verbindungselement erstreckt sich bis zum gegenüberliegenden weiteren Schalungselement, so dass das zweite Verbindungselement im betonierten Zustand an der entsprechenden Längsseite des Bauelements frei zugänglich ist.In the assembled state on the formwork device, the transport anchor is in this way in the formwork space between the formwork element and a further formwork element is arranged so that the first connecting element extends at least to the front of the formwork element for the application of concrete. The first connecting element preferably engages in the formwork element in the assembled state. The second connecting element extends as far as the opposite further formwork element, so that the second connecting element is freely accessible on the corresponding longitudinal side of the component in the concreted state.
Für die Zwecke dieser Offenbarung beziehen sich die Orts- und Richtungsangaben auf die Betonierstellung der Schalungseinrichtung mit vorzugsweise im Wesentlichen vertikaler Ausrichtung des Schalungselements, um das Bauelement mit Hilfe der Schalungseinrichtung zu gießen.For the purposes of this disclosure, the location and direction details relate to the concreting position of the formwork device with the formwork element preferably being oriented essentially vertically in order to pour the component with the aid of the formwork device.
Um eine einfache und stabile Verbindung des Transportankers mit dem Schalungselement zu schaffen, weist das erste Verbindungselement des Transportankers bei einer bevorzugten Ausführungsform ein erstes Gewindeteil, insbesondere einen Gewindebolzen, auf, welches mit einem zweiten Gewindeteil am Schalungselement, insbesondere einer Mutter, verbunden ist. Somit kann eine Schraubverbindung zwischen dem Transportanker und dem Schalungselement vorgesehen sein. Es kann jedoch auch eine andere Verbindung, etwa eine Rastverbindung, vorgesehen sein.In order to create a simple and stable connection between the transport anchor and the formwork element, in a preferred embodiment the first connection element of the transport anchor has a first threaded part, in particular a threaded bolt, which is connected to a second threaded part on the formwork element, in particular a nut. A screw connection can thus be provided between the transport anchor and the formwork element. However, another connection, for example a latching connection, can also be provided.
Um die Befestigung des Transportankers am Schalungselement zu erleichtern, weist das Querkraftteil bei einer bevorzugten Ausführungsform eine Durchgangsöffnung zur Anordnung des ersten Verbindungselements von der vom Schalungselement abgewandten Seite des Querkraftteils her auf. Die Durchgangsöffnung erstreckt sich bevorzugt von dem vom Schalungselement abgewandten Ende bis zu dem dem Schalungselement zugewandten Ende des Querkraftteils. Bei der Montage wird zunächst der Transportanker am Schalungselement angelegt. Anschließend wird das erste Verbindungselement von außen (d.h. von der vom Schalungselement abgewandten Seite her) durch die Durchgangsöffnung gesteckt und mit dem zweiten Verbindungselement am Schalungselement in Eingriff gebracht. Dadurch befindet sich der Transportanker in der definierten Montageposition am Schalungselement, so dass die präzise Position des Transportankers im eingegossenen Zustand im Betonkörper sichergestellt ist.In order to facilitate the attachment of the transport anchor to the formwork element, in a preferred embodiment the transverse force part has a through opening for the arrangement of the first connecting element from the side of the transverse force part facing away from the formwork element. The through opening preferably extends from the end facing away from the formwork element to the end of the transverse force part facing the formwork element. During assembly, the transport anchor is first placed on the formwork element. The first connecting element is then inserted from the outside (ie from the side facing away from the formwork element) through the through opening and brought into engagement with the second connecting element on the formwork element. As a result, the transport anchor is in the defined assembly position on the formwork element, so that the precise Position of the transport anchor in the cast-in state in the concrete body is ensured.
Bevorzugt ist der Transportanker aus Metall oder Kunststoff, insbesondere faserverstärktem Kunststoff, oder einer Verbindung daraus gefertigt.The transport anchor is preferably made of metal or plastic, in particular fiber-reinforced plastic, or a connection therefrom.
Um die Übertragung von Längskräften auf das Bauelement zu verbessern, weist der Transportanker bevorzugt einen Ankerbolzen, insbesondere mit einer Hinterschneidung, auf, welcher im einbetonierten Zustand bevorzugt im Wesentlichen entlang der Hauptebene des Bauelements (d.h. bei einem plattenförmigen Betonfertigteil parallel zu den zwei Längsseiten, welche über im Vergleich dazu schmälere Stirnseiten miteinander verbunden sind) angeordnet ist.In order to improve the transmission of longitudinal forces to the structural element, the transport anchor preferably has an anchor bolt, in particular with an undercut, which in the concreted-in state preferably essentially extends along the main plane of the structural element (i.e. in the case of a plate-shaped precast concrete part parallel to the two long sides, which are connected to one another via, in comparison, narrower end faces).
Um eine reversibel lösbare Anbindung des Stützelements zu ermöglichen, kann das zweite Verbindungselement ein Gewindeelement, insbesondere mit einem Innengewinde, sein. Somit kann das Stützelement über eine Schraubverbindung mit dem Gewindeelement verbunden werden.In order to enable a reversibly detachable connection of the support element, the second connection element can be a threaded element, in particular with an internal thread. The support element can thus be connected to the threaded element via a screw connection.
Bei einer bevorzugten Ausführungsform weist das Anschlussteil eine - bezogen auf den betonierten Zustand des Bauelements - bis zu einer Stirnseite des Bauelements reichende Anschlusshülse, insbesondere mit einem Innengewinde, auf. An der Anschlusshülse kann die Hebeeinrichtung befestigt sein, mit welcher das Bauelement gehandhabt werden kann. Die Längsachse der Anschlusshülse verläuft bevorzugt im Wesentlichen parallel zur Haupterstreckungsebene des Bauelements, insbesondere im Wesentlichen senkrecht zur Stirnseite, an der die Anschlusshülse mündet.In a preferred embodiment, the connection part has a connection sleeve, in particular with an internal thread, which extends as far as an end face of the component, based on the concreted state of the component. The lifting device with which the component can be handled can be attached to the connecting sleeve. The longitudinal axis of the connecting sleeve preferably runs essentially parallel to the main plane of extent of the component, in particular essentially perpendicular to the end face at which the connecting sleeve opens.
Bei einer weiteren bevorzugten Ausführungsform weist das Querkraftteil eine Querkrafthülse auf, wobei am ersten Ende der Querkrafthülse eine erste Verbreiterung und/oder am zweiten Ende der Querkrafthülse eine zweite Verbreiterung vorgesehen ist. Mit der ersten bzw. zweiten Verbreiterung, insbesondere über deren Innenseiten, kann eine besonders wirksame Ableitung der Querkräfte erzielt werden. Die erste und/oder zweite Verbreiterung kann als Scheibe oder Platte ausgeführt sein, wobei an der Innenseite der ersten bzw. zweiten Verbreiterung die Lastübertragungsfläche ausgebildet sein kann. Damit wird ein besonders großer Ausbruchskegel erzielt.In a further preferred embodiment, the transverse force part has a transverse force sleeve, a first widening being provided at the first end of the transverse force sleeve and / or a second widening being provided at the second end of the transverse force sleeve. With the first or second widening, in particular over the inside thereof, a particularly effective dissipation of the transverse forces can be achieved. The first and / or second widening can be designed as a disk or plate, with on the inside the first or second widening, the load transfer surface can be formed. A particularly large breakout cone is thus achieved.
Bei einer weiteren bevorzugten Ausführungsform ist eine Schutzkappe lösbar an der ersten und/oder zweiten Verbreiterung des Querkraftteils angeordnet.
Besonders bevorzugt ist eine Ausführungsform mit zwei Schalungselementen, insbesondere Schalungsplatten, welche an ersten Endbereichen verschwenkbar miteinander verbunden sind, so dass die Schalungselemente von einem stehenden Zustand in einen liegenden Zustand überführbar sind. Eine solche "Schmetterlingsschalung" ist beispielsweise aus der
An embodiment with two formwork elements, in particular formwork panels, which are pivotably connected to one another at first end regions, so that the formwork elements can be transferred from a standing state to a lying state, is particularly preferred. Such a "butterfly formwork" is for example from the
Zum Gießen des Bauelements kann eine Batterieschalung verwendet werden, bei welcher ein Schalungsraum zwischen dem Schalungselement der zuvor beschriebenen Schalungseinrichtung und einem weiteren Schalungselement ausgebildet ist. Das weitere Schalungselement kann eine einzelne Schalungsplatte sein. Zudem können zwei weitere Schalungselemente an ihren ersten Endbereichen verschwenkbar miteinander verbunden sein, wie oben in Zusammenhang mit der Schalungseinrichtung erläutert wurde. In diesem Fall ist der Schalungsraum zwischen der Schalungseinrichtung und einem der weiteren Schalungselemente ausgebildet. Selbstverständlich kann eine solche Batterieschalung beliebig durch Schalungseinrichtungen und weitere Schalungselement erweitert werden, um mehrere Schalungsräume für die Fertigung mehrerer Bauelemente auszubilden.A battery formwork can be used to cast the component, in which a formwork space between the formwork element the formwork device described above and a further formwork element is formed. The further formwork element can be a single formwork panel. In addition, two further formwork elements can be pivotably connected to one another at their first end regions, as was explained above in connection with the formwork device. In this case, the formwork space is formed between the formwork device and one of the further formwork elements. Of course, such a battery formwork can be expanded as required by formwork devices and further formwork elements in order to form several formwork spaces for the production of several components.
Bei einer bevorzugten Ausführungsform erstreckt sich das Querkraftteil der Schalungseinrichtung von der Außenseite (Vorderseite) des Schalungselements durch den Schalungsraum bis zur zugewandten Außenseite des weiteren Schalungselements. Diese Ausführung ist deshalb besonders günstig, weil eine Durchstützung zwischen der Schalungseinrichtung und dem weiteren Schalungselement erzielt wird. Somit kann eine Durchbiegung der Schalungselemente aufgrund des Betondrucks, insbesondere an den oberen Bereichen der Schalungselemente, zuverlässig verhindert werden.In a preferred embodiment, the transverse force part of the formwork device extends from the outside (front side) of the formwork element through the formwork space to the facing outside of the further formwork element. This embodiment is particularly favorable because a through-support between the formwork device and the further formwork element is achieved. In this way, bending of the formwork elements due to the concrete pressure, in particular in the upper areas of the formwork elements, can be reliably prevented.
Die zuvor beschriebene Schalungseinrichtung kann zur Herstellung eines Bauelements genutzt werden, bei welchem es sich bevorzugt um ein plattenförmiges Betonfertigteil handelt. Das Bauelement weist einen ausgehärteten Betonkörper auf, in welchen der Transportanker eingegossen ist. Der Transportanker wird also nicht nachträglich in das fertige Bauelement eingebracht (wie ein Dübel oder dergleichen), sondern vor dem Gießen des Bauelements im Schalungsraum angeordnet. Der Transportanker ist daher als Einlegeteil ausgebildet.The formwork device described above can be used to produce a structural element which is preferably a plate-shaped precast concrete part. The component has a hardened concrete body in which the transport anchor is cast. The transport anchor is therefore not subsequently introduced into the finished component (like a dowel or the like), but rather is arranged in the formwork space before the component is poured. The transport anchor is therefore designed as an insert.
Bei einer besonders bevorzugten Ausführung erstreckt sich das Querkraftteil in Dickenrichtung des Betonkörpers von der einen Längsseite bis zur anderen Längsseite des Betonkörpers, welcher bevorzugt als Platte ausgebildet ist.In a particularly preferred embodiment, the transverse force part extends in the thickness direction of the concrete body from one longitudinal side to the other longitudinal side of the concrete body, which is preferably designed as a plate.
