Definitions
- the present invention relates to a parapet anchor for fastening parapet or concrete elements.
- the invention also relates to a building with a parapet.
- Parapet anchors are used to attach reinforced concrete ceilings, balconies or wide girders to precast concrete, parapet or parapet panels.
- the parapet anchors are concreted into the precast concrete parapets so that they can be transported to the construction site as a prefabricated component.
- some parapet anchors can also be installed on site, for example on a facade.
- two anchors are usually used per precast element.
- Known parapet anchors often have a profile rail that is connected to a support element which is cast into the prefabricated component or mounted on it. It is important here that the profile rail, the support element and the connection between the profile rail and the support element are designed to be particularly stable in order not to bend even under a high load. It must be taken into account that the load exerts a tensile force and a compressive force on the parapet anchor, the distribution of which can vary, for example due to an incalculable additional wind load.
- the DE 298 12 886 U1 describes a balcony and parapet anchor for mounting a balcony slab on a reinforced concrete ceiling, consisting of two V4A steel plates, which are connected to each other with four hexagon bolts and hexagon nuts.
- the spacing of the V4A steel plates can be precisely determined using lock nuts.
- Tensile and compressive forces are introduced into the balcony slab and the reinforced concrete slab using the anchoring plates that are mounted on the V4A steel plates. Accordingly, the entire load force is transmitted into the load-bearing component without differentiating between tensile and compressive forces. Accordingly, all elements of the balcony and parapet anchor must be designed in such a way that they can bear the entire load, composed of tensile and compressive forces. This severely limits the design optimizability.
- the DE 39 10 286 A1 describes a device for anchoring components to a load-bearing anchoring base, with an anchoring element that can be fastened on or in the anchoring base and with a connecting part protruding therefrom towards the side facing away from the anchoring base in the installation position.
- the connecting part can be connected to the component to be anchored or can be embedded in the latter.
- Between the anchoring element that can be fastened on or in the anchoring base and that of the latter protruding connection part is arranged in a direction transverse to the load bearing displacement between the anchoring element and the connection part, but rigid in the load direction.
- the device serves in particular to compensate for the dilation movements of the parapet element that occur under the influence of temperature via a specially designed bearing.
- the DE 199 08 388 A1 discloses a component for thermal insulation between a building and a cantilevered outer part, in particular a steel component, consisting of an insulating body to be laid between them with integrated reinforcing bars in the form of tension and compression bars and at least one transverse force bar, with at least some of the reinforcing bars on the side facing away from the building Insulating body carry a fastening device for mounting the protruding outer part and wherein a connecting element is provided for connecting the protruding outer part to the fastening device.
- the object of the present invention is to provide a parapet anchor that is optimized in terms of load distribution and a building with parapet equipped therewith.
- a parapet anchor according to the invention enables optimized load transfer by efficiently dissipating vertical and horizontal forces occurring in parapets.
- a parapet anchor according to the invention comprises a vertically oriented first anchoring bolt and a horizontally oriented second anchoring bolt which is spaced apart from the first anchoring bolt.
- the anchoring bolts are concreted into the facade to be built later (i.e. concrete slab) or another parapet component.
- a special feature of the parapet anchor according to the invention is that a load, differentiated according to tensile force and compressive force, can be diverted to both anchoring bolts in a ceiling plate. Due to the alignment of the anchoring bolts within the parapet plate, the pair of forces is differentiated in that a vertical force acting from top to bottom is introduced as a compressive force in the horizontally aligned second anchoring bolt, while the resulting tensile force is introduced into the vertically aligned first anchoring bolt. This is achieved by means of appropriate tension, compression and transverse force struts, which introduce the vertical force into an on-site ceiling panel (e.g. reinforced concrete panel).
- an on-site ceiling panel e.g. reinforced concrete panel
- the parapet anchor comprises at least one tensile force strut connected non-positively to the first anchoring bolt and running transversely to this, and at least one compressive force strut connected non-positively to the second anchoring bolt and running transversely to this.
- the tensile force strut serves to pass on and transfer the tensile force introduced onto the first anchoring bolt and the compressive force strut serves to pass on and transmit the compressive force introduced onto the second anchoring bolt. It goes without saying that under certain circumstances an inverted introduction and transmission of force is also possible, i.e. that the first anchoring bolt absorbs compressive forces and accordingly transmits the compressive force via the tensile force strut and the second anchoring bolt absorbs tensile forces and passes them on via the compressive force strut.
- the parapet anchor according to the invention comprises at least one transverse force strut with a first section which is arranged in the plane of the tensile force strut and a second section which is angled towards the second anchoring bolt and connected to it in a force-locking manner.
- the transverse force strut connects the level that is used to transfer the compressive forces with the level that is used to transfer the tensile forces.
- the transverse force strut is subject to tensile stress.
- the compressive force struts, the tensile force struts and the transverse force struts are set in concrete, for example, in a concrete ceiling and are intended to replace the classic steel girder.
- the two anchoring bolts ensure optimized load transfer, even in a very thin concrete slab.
- a moment load can also be efficiently removed.
- a force couple consisting of a tensile force and a compressive force.
- the pressure force from the parapet is introduced into the lower anchoring bolt and the tensile force is introduced into the upper anchoring bolt.
- the compressive force in the lower anchoring bolts is then introduced as a compressive force into an on-site ceiling panel by the compressive force strut.
- the tensile force in the upper anchoring bolt is then introduced as tensile force into the on-site ceiling panel by the tensile force strut.
- the moment load can also act unplanned in the other direction, in which case the tensile force would then convert to the compressive force or vice versa as described above.
- the two anchoring bolts are preferably aligned orthogonally to one another.
- the second anchoring bolt is arranged in a plane below the first anchoring bolt.
- the first anchoring bolt and / or the second anchoring bolt are designed as round bolts.
- the tensile strut consists of two approximately parallel reinforcing rods which are brought together at one end in a U-profile for receiving the first anchoring bolt and connected to it in a force-locking manner.
- the U-profile is adapted to the scope of the anchoring bolt. It has been shown that this connection between the first anchoring bolt and the parallel reinforcing bars of the tensile force strut leads to a uniform distribution of the force acting on the anchoring bolt on the parallel reinforcing bars. As a result, the load-bearing capacity of the parapet anchor can be increased overall.
- the compression strut consists of two approximately parallel reinforcing bars which are non-positively connected at one end to the second anchoring bolt. This divides the compressive force over two reinforcing bars, which increases the efficiency of the load transfer and reduces the load on the individual reinforcing bar.
- the reinforcing bars of the first section of the transverse force strut are arranged between the two reinforcing bars of the first tensile force strut.
- the transverse force strut consists of two approximately parallel reinforcing bars, which in their second section have a profile adapted to the geometry of the anchoring bolt, preferably a U-shaped profile, to accommodate the second anchoring bolt are brought together and positively connected to this.
- the transverse force struts do not run parallel to one another in their transversely guided angled section, but are brought together to the upper section, which shifts the transition to the horizontal section of the transverse force struts in the direction of the ceiling plate.
- the transverse force strut comprises the lower, second anchoring bolt in a leg region of the second section, is angled vertically upwards to the first anchoring bolt and ends with a free end.
- the first and second anchoring bolts are arranged offset to one another in the horizontal plane.
- the transverse force strut of the parapet anchor according to the invention is subjected to tensile force when the parapet anchor is used.
- the introduction and transmission of the tensile forces into the transverse force strut is particularly effective if they are in their second section at an angle ⁇ of preferably 20 ° to 60 °, preferably between 30 ° and 50 °, depending on the variant, preferably about 30 ° or 45 °, is angled to the level of the second anchorage bolt.
- the tensile force, compressive force and / or transverse force struts are provided with a connecting element in order to facilitate transport.
- the connecting element is preferably arranged in the horizontal region of the struts so that the struts can be extended as required during assembly.
- the connecting element can, for example, be a thread or coupling piece which cooperates with the respective counterpart.
- An advantage of the parapet anchor according to the invention can be seen in the fact that the tensile and compressive forces occurring in facade construction are absorbed and transmitted in an optimized manner.
- the moments that occur can be derived independently of one another via the compressive force struts and tensile force struts.
- the connection element is therefore not subjected to bending stress. This has an advantageous effect in the case of load transfer over large insulation joints.
- Another advantage of the construction according to the invention is that the cross-section of the individual struts can be smaller, which results in a lower heat transfer compared to existing solutions, since a larger thermal bridge is avoided. As a result, for example, insulation can also be carried out in smaller dimensions than was previously the case.
- the present invention also relates to a structure with a parapet comprising a parapet anchor according to the invention, the first anchoring bolt and the second anchoring bolt being concreted in a precast concrete slab, parapet slab or parapet slab.
- the tensile force strut, the compressive force strut and the transverse force strut are preferably concreted in a ceiling slab (eg reinforced concrete slab).
- the tensile force struts, the compressive force struts and the transverse force struts are preferably deformable in order to compensate for the temperature differences occurring in the summer or winter in the parapets. Parapet panels expand or contract due to temperature differences.
- a precast concrete slab as part of a facade can be made larger overall than with conventional solutions. Due to the load introduction according to the invention in the area of the first and second anchoring bolts, there is less longitudinal deformation and smaller cross-sections of the struts are also possible. In this way, for example, the load transfer of the connection element can be optimized in a thin concrete slab of a parapet (e.g. with a slab thickness of 80 mm or more).

- the U-profile 7 encloses a section of the second anchoring bolt 2 and is connected to it in a force-locking manner, for example via a welded connection.
- the reinforcing bars of the transverse force strut 5 run in the first section 5.1 first in the first plane until they are finally angled downwards in the area of a cross bridge 8.1 at an angle to the plane of the second anchoring bolt 2 in the second section 5.2. Via a second transverse transverse bridge 8.2 which is offset in the longitudinal direction from the first transverse bridge 8.1.

Description
Die vorliegende Erfindung betrifft einen Brüstungsanker zur Befestigung von Brüstungs- oder Betonelementen. Die Erfindung betrifft ferner ein Bauwerk mit Brüstung.The present invention relates to a parapet anchor for fastening parapet or concrete elements. The invention also relates to a building with a parapet.
Brüstungsanker dienen der Befestigung von Stahlbetondecken, Balkonen oder breiten Trägern an Betonfertigteil-, Brüstungs- oder Attikaplatten. Üblicherweise werden die Brüstungsanker in die Betonfertigteilbrüstungen einbetoniert, um als Fertigbauteil zur Baustelle transportiert werden zu können. Alternativ lassen sich aber auch einige Brüstungsanker vor Ort, beispielsweise an einer Fassade montieren. Um eine gleichmäßige Lastenverteilung zu gewährleisten, werden für gewöhnlich zwei Anker pro Fertigbauteil verwendet.Parapet anchors are used to attach reinforced concrete ceilings, balconies or wide girders to precast concrete, parapet or parapet panels. Usually the parapet anchors are concreted into the precast concrete parapets so that they can be transported to the construction site as a prefabricated component. Alternatively, some parapet anchors can also be installed on site, for example on a facade. To ensure even load distribution, two anchors are usually used per precast element.
Bekannte Brüstungsanker weisen häufig eine Profilschiene auf, die mit einem Tragelement verbunden ist, welches in das Fertigbauteil eingegossen oder an diesem montiert ist. Dabei ist es wichtig, dass die Profilschiene, das Tragelement und die Verbindung zwischen Profilschiene und Tragelement besonders stabil ausgebildet ist, um auch unter einer hohen Traglast nicht zu verbiegen. Dabei ist zu berücksichtigen, dass die Traglast auf den Brüstungsanker eine Zugkraft und eine Druckkraft ausübt, deren Verteilung, beispielsweise durch eine unkalkulierbare zusätzliche Windlast, variieren kann.Known parapet anchors often have a profile rail that is connected to a support element which is cast into the prefabricated component or mounted on it. It is important here that the profile rail, the support element and the connection between the profile rail and the support element are designed to be particularly stable in order not to bend even under a high load. It must be taken into account that the load exerts a tensile force and a compressive force on the parapet anchor, the distribution of which can vary, for example due to an incalculable additional wind load.

Demnach berücksichtigen die bisher bekannten Vorrichtungen nicht im ausreichenden Maße die bei Brüstungsankern auftretenden Zug- und Druckkräfte im Fassadenbau. Hier besteht Verbesserungsbedarf.Accordingly, the devices known up to now do not take sufficient account of the tensile and compressive forces that occur with parapet anchors in facade construction. There is a need for improvement here.
Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, einen hinsichtlich der Lastenverteilung optimierten Brüstungsanker sowie ein damit ausgerüstetes Bauwerk mit Brüstung bereitzustellen.Against this background, the object of the present invention is to provide a parapet anchor that is optimized in terms of load distribution and a building with parapet equipped therewith.
Diese Aufgabe wird gelöst durch einen Brüstungsanker gemäß Anspruch 1 und ein Bauwerk mit Brüstung gemäß Anspruch 13. Bevorzugte Ausführungsformen finden sich in den Unteransprüchen wieder.This object is achieved by a parapet anchor according to
Der erfindungsgemäße Brüstungsanker ermöglicht einen optimierten Lastabtrag durch eine effiziente Ableitung von bei Brüstungen auftretenden Vertikal- und Horizontalkräften. Ein erfindungsgemäßer Brüstungsanker umfasst hierzu einen vertikal ausgerichteten ersten Verankerungsbolzen und einen zum ersten Verankerungsbolzen beabstandeten, horizontal ausgerichteten zweiten Verankerungsbolzen. Die Verankerungsbolzen werden in der später zu errichtenden Fassade (d.h. Betonplatte) oder einem anderen Brüstungsbauteil einbetoniert.The parapet anchor according to the invention enables optimized load transfer by efficiently dissipating vertical and horizontal forces occurring in parapets. For this purpose, a parapet anchor according to the invention comprises a vertically oriented first anchoring bolt and a horizontally oriented second anchoring bolt which is spaced apart from the first anchoring bolt. The anchoring bolts are concreted into the facade to be built later (i.e. concrete slab) or another parapet component.
Eine Besonderheit des erfindungsgemäßen Brüstungsankers besteht darin, dass eine Last differenziert nach Zugkraft und Druckkraft auf beide Verankerungsbolzen verteilt in eine Deckenplatte ableitbar ist. Aufgrund der Ausrichtung der Verankerungsbolzen innerhalb der Brüstungsplatte, differenziert sich das Kräftepaar dahingehend, dass eine von oben nach unten wirkende Vertikalkraft als Druckraft in den horizontal ausgerichteten zweiten Verankerungsbolzen eingeleitet wird, während die dabei entstehende Zugkraft in den vertikal ausgerichteten ersten Verankerungsbolzen eingeleitet wird. Erreicht wird dies durch entsprechende Zug-, Druck- und Querkraftstreben, welche die Vertikalkraft in eine bauseitige Deckenplatte (z.B. Stahlbetonplatte) einleiten.A special feature of the parapet anchor according to the invention is that a load, differentiated according to tensile force and compressive force, can be diverted to both anchoring bolts in a ceiling plate. Due to the alignment of the anchoring bolts within the parapet plate, the pair of forces is differentiated in that a vertical force acting from top to bottom is introduced as a compressive force in the horizontally aligned second anchoring bolt, while the resulting tensile force is introduced into the vertically aligned first anchoring bolt. This is achieved by means of appropriate tension, compression and transverse force struts, which introduce the vertical force into an on-site ceiling panel (e.g. reinforced concrete panel).
Um den erfindungsgemäßen Lastabtrag zu erreichen, umfasst der Brüstungsanker wenigstens eine mit dem ersten Verankerungsbolzen kraftschlüssig verbundene und quer zu diesem verlaufende Zugkraftstrebe und wenigstens eine mit dem zweiten Verankerungsbolzen kraftschlüssig verbundene und quer zu diesem verlaufende Druckkraftstrebe.
Die Zugkraftstrebe dient der Weiterleitung und Übertragung der auf den ersten Verankerungsbolzen eingeleiteten Zugkraft und die Druckkraftstrebe dient der Weiterleitung und Übertragung der auf den zweiten Verankerungsbolzen eingeleiteten Druckkraft. Es versteht sich, dass unter gewissen Umständen auch eine invertierte Krafteinleitung und Weiterleitung möglich ist, also dass der erste Verankerungsbolzen Druckkräfte aufnimmt und entsprechend über die Zugkraftstrebe die Druckkraft weiterleitetet und der zweite Verankerungsbolzen Zugkräfte aufnimmt und diese über die Druckkraftstrebe weiterleitet.In order to achieve the load transfer according to the invention, the parapet anchor comprises at least one tensile force strut connected non-positively to the first anchoring bolt and running transversely to this, and at least one compressive force strut connected non-positively to the second anchoring bolt and running transversely to this.
The tensile force strut serves to pass on and transfer the tensile force introduced onto the first anchoring bolt and the compressive force strut serves to pass on and transmit the compressive force introduced onto the second anchoring bolt. It goes without saying that under certain circumstances an inverted introduction and transmission of force is also possible, i.e. that the first anchoring bolt absorbs compressive forces and accordingly transmits the compressive force via the tensile force strut and the second anchoring bolt absorbs tensile forces and passes them on via the compressive force strut.
Außerdem umfasst der erfindungsgemäße Brüstungsanker wenigstens eine Querkraftstrebe mit einem ersten Abschnitt, welcher in der Ebene der Zugkraftstrebe angeordnet ist und einem zweiten Abschnitt, welcher zum zweiten Verankerungsbolzen abgewinkelt und mit diesem kraftschlüssig verbunden ist. Die Querkraftstrebe verbindet die Ebene, die zur Weiterleitung der Druckkräfte dient, mit der Ebene, die zur Weiterleitung der Zugkräfte dient. Die Querkraftstrebe wird erfindungsgemäß auf Zug beansprucht. Die Druckkraftstreben, die Zugkraftstreben und die Querkraftstreben werden beispielsweise in einer Betondecke einbetoniert und sollen den klassischen Stahlträger ersetzen. Die beiden Verankerungsbolzen sorgen für einen optimierten Lastabtrag, auch in eine sehr dünne Betonplatte.In addition, the parapet anchor according to the invention comprises at least one transverse force strut with a first section which is arranged in the plane of the tensile force strut and a second section which is angled towards the second anchoring bolt and connected to it in a force-locking manner. The transverse force strut connects the level that is used to transfer the compressive forces with the level that is used to transfer the tensile forces. According to the invention, the transverse force strut is subject to tensile stress. The compressive force struts, the tensile force struts and the transverse force struts are set in concrete, for example, in a concrete ceiling and are intended to replace the classic steel girder. The two anchoring bolts ensure optimized load transfer, even in a very thin concrete slab.
Durch den erfindungsgemäßen Brüstungsanker kann ferner auch eine Momentenbeanspruchung effizient abgetragen werden. Wird beispielsweise eine Brüstungsfläche durch horizontale Lasten, z.B. eine Windbeanspruchung, momentenbeansprucht, so wird diese Momentenbeanspruchung über ein Kräftepaar, bestehend aus einer Zugkraft und einer Druckkraft, abgetragen. Hierbei wird die Druckraft aus der Brüstung in den unteren Verankerungsbolzen eingeleitet und die Zugkraft in den oberen Verankerungsbolzen eingeleitet. Die Druckkraft in den unteren Verankerungsbolzen wird dann durch die Druckkraftsrebe als Druckkraft in eine bauseitige Deckenplatte eingeleitet. Die Zugkraft in dem oberen Verankerungsbolzen wird dann durch die Zugkraftstrebe als Zugkraft in die bauseitige Deckenplatte eingeleitet. Die Momentenbeanspruchung kann auch unplanmäßig in die andere Richtung wirken, wobei in diesem Fall dann die Zug- zur Druckkraft oder umgekehrt wie oben beschrieben konvertieren würde.By means of the parapet anchor according to the invention, a moment load can also be efficiently removed. For example, if a parapet is exposed to horizontal loads, e.g. a wind load, moment-loaded, this moment load is carried away by a force couple consisting of a tensile force and a compressive force. The pressure force from the parapet is introduced into the lower anchoring bolt and the tensile force is introduced into the upper anchoring bolt. The compressive force in the lower anchoring bolts is then introduced as a compressive force into an on-site ceiling panel by the compressive force strut. The tensile force in the upper anchoring bolt is then introduced as tensile force into the on-site ceiling panel by the tensile force strut. The moment load can also act unplanned in the other direction, in which case the tensile force would then convert to the compressive force or vice versa as described above.
Die beiden Verankerungsbolzen sind vorzugsweise orthogonal zueinander ausgerichtet. Bei einer bevorzugten Weiterbildung ist vorgesehen, dass der zweite Verankerungsbolzen in einer Ebene unterhalb des ersten Verankerungsbolzens angeordnet ist. In einer weiter bevorzugten Variante sind der erste Verankerungsbolzen und/oder der zweite Verankerungsbolzen als Rundbolzen ausgebildet.The two anchoring bolts are preferably aligned orthogonally to one another. In a preferred development it is provided that the second anchoring bolt is arranged in a plane below the first anchoring bolt. In a further preferred variant the first anchoring bolt and / or the second anchoring bolt are designed as round bolts.
Bei einer bevorzugten Ausführungsform ist vorgesehen, dass die Zugkraftstrebe aus zwei in etwa parallel verlaufenden Bewehrungsstäben besteht, welche an einem Ende in ein U-Profil zur Aufnahme des ersten Verankerungsbolzens zusammengeführt und mit diesem kraftschlüssig verbunden sind. Das U-Profil ist hierbei an den Umfang des Verankerungsbolzens angepasst. Es hat sich gezeigt, dass diese Verbindung zwischen erstem Verankerungsbolzen und den parallel verlaufenden Bewehrungsstäben der Zugkraftstrebe zu einer gleichmäßigen Verteilung der auf den Verankerungsbolzen wirkenden Kraft auf die parallel verlaufenden Bewehrungsstäben führt. Dadurch kann die Tragleistung des Brüstungsankers insgesamt gesteigert werden.In a preferred embodiment it is provided that the tensile strut consists of two approximately parallel reinforcing rods which are brought together at one end in a U-profile for receiving the first anchoring bolt and connected to it in a force-locking manner. The U-profile is adapted to the scope of the anchoring bolt. It has been shown that this connection between the first anchoring bolt and the parallel reinforcing bars of the tensile force strut leads to a uniform distribution of the force acting on the anchoring bolt on the parallel reinforcing bars. As a result, the load-bearing capacity of the parapet anchor can be increased overall.
Entsprechend einer bevorzugten Ausführungsform ist vorgesehen, dass die Druckkraftstrebe aus zwei in etwa parallel verlaufenden Bewehrungsstäben besteht, welche an einem Ende mit dem zweiten Verankerungsbolzen kraftschlüssig verbunden sind. Hierdurch teilt sich die Druckkraft auf zwei Bewehrungsstäbe auf, was die Effizienz des Lastabtrags steigert und die Belastung des einzelnen Bewehrungsstabs vermindert.According to a preferred embodiment, it is provided that the compression strut consists of two approximately parallel reinforcing bars which are non-positively connected at one end to the second anchoring bolt. This divides the compressive force over two reinforcing bars, which increases the efficiency of the load transfer and reduces the load on the individual reinforcing bar.
Bei einer bevorzugten Ausführungsform ist vorgesehen, dass die Bewehrungsstäbe des ersten Abschnitts der Querkraftstrebe zwischen den beiden Bewehrungsstäben der ersten Zugkraftstrebe angeordnet sind.In a preferred embodiment it is provided that the reinforcing bars of the first section of the transverse force strut are arranged between the two reinforcing bars of the first tensile force strut.
Entsprechend den bereits oben dargelegten Vorteilen ist bei einer bevorzugten Ausführungsform vorgesehen, dass die Querkraftstrebe aus zwei in etwa parallel verlaufenden Bewehrungsstäben besteht, welche in ihrem zweiten Abschnitt in einem der Geometrie des Verankerungsbolzen angepassten Profil, vorzugsweise einem U-Profil, zur Aufnahme des zweiten Verankerungsbolzens zusammengeführt und mit diesem kraftschlüssig verbunden sind.In accordance with the advantages already outlined above, a preferred embodiment provides that the transverse force strut consists of two approximately parallel reinforcing bars, which in their second section have a profile adapted to the geometry of the anchoring bolt, preferably a U-shaped profile, to accommodate the second anchoring bolt are brought together and positively connected to this.
In einer alternativen Ausführungsform verlaufen die Querkraftstreben in ihrem quer geführten abgewinkelten Abschnitt nicht parallel zueinander, sondern werden zum oberen Abschnitt zusammengeführt, was den Übergang in den horizontalen Abschnitt der Querkraftstreben in Richtung Deckenplatte verlagert.In an alternative embodiment, the transverse force struts do not run parallel to one another in their transversely guided angled section, but are brought together to the upper section, which shifts the transition to the horizontal section of the transverse force struts in the direction of the ceiling plate.
In einer weiteren Ausführungsform umfasst die Querkraftstrebe den unteren zweiten Verankerungsbolzen in einem Schenkelbereich des zweiten Abschnitts, ist vertikal nach oben zum ersten Verankerungsbolzen abgewinkelt und endet mit einem freien Ende. Vorzugsweise sind hierbei der erste und der zweite Verankerungsbolzen in der horizontalen Ebene versetzt zueinander angeordnet.In a further embodiment, the transverse force strut comprises the lower, second anchoring bolt in a leg region of the second section, is angled vertically upwards to the first anchoring bolt and ends with a free end. Preferably the first and second anchoring bolts are arranged offset to one another in the horizontal plane.
Die Querkraftstrebe des erfindungsgemäßen Brüstungsankers wird bei Verwendung des Brüstungsankers mit Zugkraft beansprucht. Die Einleitung und Weiterleitung der Zugkräfte in die Querkraftstrebe ist besonders effektiv, wenn sie in ihrem zweiten Abschnitt mit einem Winkel α von bevorzugt 20° bis 60°, vorzugsweise zwischen 30° und 50°, je nach Variante bevorzugt etwa 30° oder 45°, zur Ebene des zweiten Verankerungsbolzens abgewinkelt ist.The transverse force strut of the parapet anchor according to the invention is subjected to tensile force when the parapet anchor is used. The introduction and transmission of the tensile forces into the transverse force strut is particularly effective if they are in their second section at an angle α of preferably 20 ° to 60 °, preferably between 30 ° and 50 °, depending on the variant, preferably about 30 ° or 45 °, is angled to the level of the second anchorage bolt.
In einer weiteren Ausführungsform ist vorgesehen, dass die Zugkraft-, Druckkraft- und/oder Querkraftstreben mit einem Verbindungselement versehen sind, um den Transport zu erleichtern. Vorzugsweise ist das Verbindungselement im horizontalen Bereich der Streben angeordnet, so dass die Streben bei Montage bedarfsgerecht verlängert werden können. Bei dem Verbindungselement kann es sich beispielsweise um ein Gewinde oder Kupplungsstück handeln, welches mit dem jeweiligen Gegenstück kooperiert.In a further embodiment it is provided that the tensile force, compressive force and / or transverse force struts are provided with a connecting element in order to facilitate transport. The connecting element is preferably arranged in the horizontal region of the struts so that the struts can be extended as required during assembly. The connecting element can, for example, be a thread or coupling piece which cooperates with the respective counterpart.
Ein Vorteil des erfindungsgemäßen Brüstungsankers ist darin zu sehen, dass die im Fassadenbau auftretenden Zug- und Druckkräfte in optimierter Weise abgefangen und übertragen werden. Dabei können die auftretenden Momente unabhängig voneinander über die Druckkraftstreben und Zugkraftstreben abgeleitet werden. Das Anschlusselement wird daher nicht auf Biegung beansprucht. Dies wirkt sich vorteilhaft bei einem Lastabtrag übergroße Dämmfugen hinweg aus. Ein weiterer Vorteil ist bei der erfindungsgemäßen Konstruktion ferner zu sehen, dass der Querschnitt der einzelnen Streben geringer ausfallen kann, wodurch ein im Vergleich zu bestehenden Lösungen geringerer Wärmeübertrag erfolgt, da eine größere Wärmebrücke vermieden wird. Dadurch kann beispielsweise auch eine Dämmung in geringeren Dimensionen ausgeführt werden als es bislang üblich war.An advantage of the parapet anchor according to the invention can be seen in the fact that the tensile and compressive forces occurring in facade construction are absorbed and transmitted in an optimized manner. The moments that occur can be derived independently of one another via the compressive force struts and tensile force struts. The connection element is therefore not subjected to bending stress. This has an advantageous effect in the case of load transfer over large insulation joints. Another advantage of the construction according to the invention is that the cross-section of the individual struts can be smaller, which results in a lower heat transfer compared to existing solutions, since a larger thermal bridge is avoided. As a result, for example, insulation can also be carried out in smaller dimensions than was previously the case.
Gegenstand der vorliegenden Erfindung ist auch ein Bauwerk mit Brüstung umfassend einen erfindungsgemäßen Brüstungsanker, wobei der erste Verankerungsbolzen und der zweite Verankerungsbolzen in einer Betonfertigteilplatte, Brüstungsplatte oder Attikaplatte einbetoniert sind. Dabei ist vorzugsweise die Zugkraftstrebe, die Druckkraftstrebe und die Querkraftstrebe in einer Deckenplatte (z.B. Stahlbetonplatte) einbetoniert. Vorzugsweise sind die Zugkraftstreben, die Druckkraftstreben und die Querkraftstreben verformbar, um die im Sommer bzw. Winter auftretenden Temperaturunterschiede bei Brüstungen auszugleichen. Durch Temperaturunterschiede dehnen sich Brüstungsplatten aus oder ziehen sich zusammen. Bei den bislang bekannten Brüstungsankern entstehen hierbei hohe Zwangskräfte, da diese die Verformung in horizontaler Richtung, parallel zur Fuge, behindern. Der erfindungsgemäße Brüstungsanker hingegen ist in dieser Richtung sehr weich, d.h. die entstehenden Zwangskräfte sind somit deutlich geringer. Aufgrund dieser Vorteile kann beispielsweise auf den Einsatz von Weichfaserplatten verzichtet werden.The present invention also relates to a structure with a parapet comprising a parapet anchor according to the invention, the first anchoring bolt and the second anchoring bolt being concreted in a precast concrete slab, parapet slab or parapet slab. The tensile force strut, the compressive force strut and the transverse force strut are preferably concreted in a ceiling slab (eg reinforced concrete slab). The tensile force struts, the compressive force struts and the transverse force struts are preferably deformable in order to compensate for the temperature differences occurring in the summer or winter in the parapets. Parapet panels expand or contract due to temperature differences. In the case of the parapet anchors known up to now, high constraining forces arise here, since they hinder the deformation in the horizontal direction, parallel to the joint. The inventive Parapet anchor, however, is very soft in this direction, ie the resulting constraining forces are significantly lower. Due to these advantages, for example, the use of soft fiber boards can be dispensed with.
Außerdem kann durch die optimierte Kraftableitung beispielsweise eine Betonfertigteilplatte als Teil einer Fassade insgesamt größer dimensioniert werden als dies bei herkömmlichen Lösungen der Fall war. Aufgrund der erfindungsgemäßen Lasteinleitung im Bereich des ersten und zweiten Verankerungsbolzens erfolgt eine geringere Längsverformung und es sind auch geringere Querschnitte der Streben möglich. Dadurch kann beispielsweise eine optimierte Lasteinleitung des Anschlusselementes in eine dünne Betonplatte einer Brüstung (z.B. mit einer Plattenstärke ab 80 mm) erfolgen.In addition, thanks to the optimized force dissipation, a precast concrete slab as part of a facade, for example, can be made larger overall than with conventional solutions. Due to the load introduction according to the invention in the area of the first and second anchoring bolts, there is less longitudinal deformation and smaller cross-sections of the struts are also possible. In this way, for example, the load transfer of the connection element can be optimized in a thin concrete slab of a parapet (e.g. with a slab thickness of 80 mm or more).
Eine bevorzugte Ausführungsform der Erfindung wird anhand der beigefügten Zeichnung näher erläutert.A preferred embodiment of the invention is explained in more detail with reference to the accompanying drawing.

Quer zu dem zweiten Verankerungsbolzen 2 verlaufen entlang der unteren Ebene zwei im Wesentlichen parallel zueinander angeordnete Bewehrungsstäbe einer Druckkraftstrebe 4. Die Bewehrungsstäbe der Druckkraftstrebe 4 sind mit einer Stirnseite des zweiten Verankerungsbolzens 2 kraftschlüssig verbunden, vorzugsweise durch verschweißen.Two reinforcing bars of a
Der Abstand der beiden Bewehrungsstäbe der Druckkraftstrebe 4 zueinander ist in der gezeigten Ausführungsvariante bevorzugt größer als der Abstand der beiden Bewehrungsstäbe der Zugkraftstrebe 3. Demzufolge verlaufen die Bewehrungsstäbe der Druckkraftstrebe 4 nicht unmittelbar unterhalb den Bewehrungsstäben der Zugkraftstrebe 3, sondern leicht nach Außen versetzt.The distance between the two reinforcement bars of the
Des Weiteren ist der zweite Verankerungsbolzen 2 kraftschlüssig mit einer in einem zweiten Abschnitt 5.2 nach oben ansteigenden Querkraftstrebe 5 verbunden, die in einem ersten Abschnitt 5.1 parallel zwischen den in der oberen Ebene verlaufenden Bewährungsstäben der Zugkraftrebe 3 verläuft. Die Querkraftstrebe 5 besteht in der gezeigten Ausführungsvariante aus zwei in etwa parallel verlaufenden Bewehrungsstäben, welche in ihrem zweiten Abschnitt 5.2 in ein U-Profil 7 am Verankerungsbolzen 2 zusammengeführt sind. Das U-Profil 7 umschließt hierbei einen Abschnitt des zweiten Verankerungsbolzens 2 und ist mit diesem kraftschlüssig verbunden, beispielsweise über eine Schweißverbindung. Die Bewehrungsstäbe der Querkraftstrebe 5 verlaufen im ersten Abschnitt 5.1 zunächst in der ersten Ebene bis sie schließlich in Bereich einer Querbrücke 8.1 nach unten mit einem Winkel zur Ebene des zweiten Verankerungsbolzens 2 im zweiten Abschnitt 5.2 abgewinkelt sind. Über eine zur ersten Querbrücke 8.1 in Längsrichtung versetzt angeordneten zweiten querverlaufenden Querbrücke 8.2. sind dann beide Bewehrungsstäbe der Querkraftstrebe 5 kraftschlüssig mit den Bewehrungsstäben der ersten Zugkraftstrebe 3 verbunden.Furthermore, the
Die
Die von oben nach unten wirkende Vertikalkraft wird von der Brüstung in den unteren zweiten Verankerungsbolzen 2 eingeleitet. Hierdurch entstehen eine Zugkraft in den Querkraftstreben 5 und eine Druckkraft in den Druckkraftstreben 4. Über die Druckkraftstreben 4 und die Querkraftstreben 5 wird die Vertikalkraft in die bauseitige Deckenplatte 11 eingeleitet.The vertical force acting from top to bottom is introduced from the parapet into the lower,
Durch horizontale Lasten, welche senkrecht auf die Brüstungsfläche (d.h. Brüstungsplatte 10) wirken, z.B. Windbeanspruchung, entsteht eine Momentenbeanspruchung. Diese Momentenbeanspruchung wird durch ein Kräftepaar, bestehend aus Zug- und Druckkraft, abgetragen. Hierbei wird die Druckraft aus der Brüstung in den unteren zweiten Verankerungsbolzen 2 eingeleitet und die Zugkraft in den oberen ersten Verankerungsbolzen 1 eingeleitet. Die Druckkraft in dem unteren zweiten Verankerungsbolzen 2 wird dann durch die Druckkraftstreben 4 als Druckkraft in die bauseitige Deckenplatte 10 eingeleitet. Die Zugkraft in dem ersten Verankerungsbolzen 1 wird dann durch die Zugkraftstreben 3 als Zugkraft in die bauseitige Deckenplatte 10 eingeleitet. Die Momentenbeanspruchung kann auch unplanmäßig in die andere Richtung wirken. Dann wird die Zugkraft zur Druckkraft oder umgekehrt.A moment load arises from horizontal loads which act perpendicularly on the parapet surface (ie parapet plate 10), for example wind loads. This moment load is determined by a force couple, consisting of tensile and compressive force, worn away. Here, the pressure force from the parapet is introduced into the lower,
Die Zugkraftstreben 3 sind somit planmäßig auf Zug und die Druckkraftstreben 4 planmäßig auf Druck beansprucht. Die Querkraftstreben 5 sind immer auf Zug beansprucht.The tensile struts 3 are thus systematically subjected to train and the compressive force struts 4 are systematically subjected to pressure. The transverse force struts 5 are always subject to train.
In
In einer hier nicht gezeigten Variante können die Zugkraftstreben 3, die Druckkraftstreben 4 und/oder die Querkraftstreben 5 im horizontal zur Deckenplatte 11 verlaufenden Abschnitt mit einem Verbindungselement (z.B. Gewinde oder Anschlusselement) ausgerüstet sein. Dies hat den Vorteil, dass der Brüstungsanker leichter transportierbar ist, da die Stäbe und das Ankersystem voneinander getrennt transportiert werden können. Die einzelnen Verlängerungsstreben werden an der Baustelle nach Bedarf an die entsprechenden Zugkraftstreben 3, die Druckkraftstreben 4 und/oder die Querkraftstreben 5 montiert.In a variant not shown here, the tensile force struts 3, the compressive force struts 4 and / or the transverse force struts 5 can be equipped with a connecting element (e.g. thread or connection element) in the section extending horizontally to the
