Definitions
- the invention relates to a device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structural part to a first load-bearing structural part, in particular a building ceiling to a balcony slab, and to a building with such a device.
- a device for subsequently connecting a prefabricated balcony to a building emerges.
- a recess is provided on the top of the balcony in which the tension rods are connected to one another.
- GB 2 567 685 A discloses the features of the preamble of claim 1.
- the present invention is based on the object of creating a device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structural part to a first load-bearing structural part, which has an advantageous structure.
- a further object of the present invention is to provide a building with such a device.
- This task is related to the device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structural part to a first load-bearing structural part by a device with the features of claim 1 solved.
- the task is solved by a structure with the features of claim 14.
- first tension rods protrude into the storage box on the first long side of the storage box, that the second tension rods protrude into the storage box on the second long side, and that the connecting device is arranged in the storage box.
- the connecting device is arranged in the storage box, the connecting device can be easily protected from environmental influences by closing the storage box. At the same time, an attractive visual appearance is obtained because the connecting device is not visible from the outside after the storage box has been closed. There is no need to pour the area of the connecting device later, for example with quick-hardening mortar or the like. This simplifies assembly on the construction site. There is no need to arrange a recess in the first or second structural part, in which the connecting device is arranged. This avoids any impairment of the appearance of the first or second part of the building.
- the tension rods protruding into the storage box on the first long side are advantageously intended for embedding in the first part of the building and the tension rods protruding into the storage box on the second long side are advantageously intended for embedding in the second part of the building.
- the tension rods are intended to introduce forces into the concrete of the building parts.
- the length of the tension rods required for this is calculated based on the forces to be transmitted.
- the length of the tension bars only those sections of the tension bars that are well embedded in concrete of sufficient strength can be fully taken into account. If recesses are subsequently filled with casting compound, the strength of the casting compound and its connection to the tension rods can often not be sufficiently guaranteed, so that tension rod sections running in the recesses cannot be included in the calculation or not to the same extent as tension rod sections protrude into in-situ concrete or into concrete cast in the precast factory.
- the entire length of the tension rods lying outside the storage box can be embedded in the first or second building part during the production of the building parts and no subsequent filling of a recess with casting compound such as mortar has to be done
- the entire length of the tension rods running outside the storage box must be taken into account when calculating the required length of the tension rods, in particular when calculating the overlap length. This means that a shorter length of the tension rods is required.
- the first tension rods and the second tension rods are advantageously arranged in a common plane that runs perpendicular to the vertical direction. This results in a favorable application of force. At the same time, the connection of the tension rods in the storage box is possible in a simple manner, since no height offset between the tension rods has to be compensated for.
- the connecting device comprises a connecting plate arranged in the storage box, to which the first tension rods and the second tension rods are fixed.
- the connecting plate is on one Long side of the storage box arranged in the storage box.
- the connecting plate is particularly advantageously arranged on the long side of the storage box that is closer to the balcony plate.
- the tension rods embedded in the building and projecting through the long side of the storage box remote from the balcony slab are preferably firmly connected to the connecting plate, for example via welded connections.
- the tension rods of the balcony slab are preferably pushed through openings in the connecting plate and fixed via screw connections, preferably via nuts.
- the connecting device advantageously comprises at least one screw connection.
- the openings in the connecting plate are advantageously dimensioned so large that tolerance compensation between the tension rods of the building and the tension rods of the balcony slab is possible.
- the storage box has at least one closable access opening through which the connecting device is accessible.
- the access opening is designed to be reclosable, so that the connecting device is accessible again after assembly by reopening the storage box.
- a simple design results when the access opening extends over the entire length and the entire width of the storage box. However, it can also be provided that the access opening only extends over the area of the storage box that covers the connecting device. In an alternative design, the access opening can only extend over the area of the threaded connections. It can also be provided that the storage box has several access openings, through which one or more threaded connections are accessible.
- the storage box is preferably filled with mineral wool as insulating material.
- the insulating material is advantageously introduced at least partially after the first and second tension rods have been connected to one another in the storage box.
- a simple one Design results when the storage box is made of plastic.
- the storage box is particularly preferably made from extruded profiles. This makes it possible to produce the storage box easily and economically.
- the storage box preferably has a base body and at least one lid that can be connected to the base body.
- the cover is preferably detachably connected to the base body.
- the cover can be connected to the base body, for example via a snap connection, a latching or clamping. Another type of connection between the cover and the base body can also be advantageous. Alternatively, it can be provided to permanently connect the cover to the base body, for example via an adhesive connection.
- the storage box can be open on its end faces, which are perpendicular to the longitudinal direction. This is particularly advantageous if several storage boxes are arranged next to one another at the front. Particularly for storage boxes that close off the insulation joint in the longitudinal direction, it is advantageously provided that the storage box is closed on at least one end face. An additional cover can be provided for this purpose.
- the storage box is advantageously designed to be closed in the transverse direction and in the vertical direction.
- At least one support for the vertical support of the second structural part is advantageously arranged on the second longitudinal side of the storage box. This makes it possible to easily subsequently assemble the second structural part on the first structural part. Subsequently means that the second structural part, for example the balcony slab, is already completely manufactured and the tension rods are embedded in the balcony slab before the balcony slab is fixed to the first structural part. This allows the building to be constructed easily and economically. Crane times can be minimized through this type of manufacturing.

- the at least one transverse force bar is fixed to the support for the vertical support of the second structural part.
- a different connection of the shear force bar can also be advantageous.
- the building has a first load-bearing structural part made of concrete and a second load-bearing structural part made of concrete as well as a device for connecting the second load-bearing structural part to the first load-bearing structural part.

Dadurch wird eine Beeinträchtigung des Erscheinungsbilds von erstem oder zweitem Bauwerksteil vermieden.It is provided that the first tension rods protrude into the storage box on the first long side of the storage box, that the second tension rods protrude into the storage box on the second long side, and that the connecting device is arranged in the storage box. Because the connecting device is arranged in the storage box, the connecting device can be easily protected from environmental influences by closing the storage box. At the same time, an attractive visual appearance is obtained because the connecting device is not visible from the outside after the storage box has been closed. There is no need to pour the area of the connecting device later, for example with quick-hardening mortar or the like. This simplifies assembly on the construction site. There is no need to arrange a recess in the first or second structural part, in which the connecting device is arranged. This avoids any impairment of the appearance of the first or second part of the building.
Durch die Anordnung in dem Verwahrkasten kann bei Verwendung von brandhemmendem Material als Isoliermaterial und/oder als Material für den Verwahrkasten gleichzeitig ein Brandschutz der Verbindungseinrichtung erreicht werden. Die an der ersten Längsseite in den Verwahrkasten ragenden Zugstäbe sind vorteilhaft zur Einbettung in das erste Gebäudeteil vorgesehen und die an der zweiten Längsseite in den Verwahrkasten ragenden Zugstäbe sind vorteilhaft zur Einbettung in das zweite Gebäudeteil vorgesehen.Due to the arrangement in the storage box, fire protection of the connecting device can be achieved at the same time when using fire-retardant material as insulating material and/or as material for the storage box. The tension rods protruding into the storage box on the first long side are advantageously intended for embedding in the first part of the building and the tension rods protruding into the storage box on the second long side are advantageously intended for embedding in the second part of the building.
Aufgrund der Anordnung der Verbindungseinrichtung im Verwahrkasten kann auf einfache Weise ein ausreichender Korrosionsschutz der Verbindungseinrichtung und der in den Verwahrkasten ragenden Abschnitte der Zugstäbe gewährleistet werden. Ein ergänzender Korrosionsschutz kann entfallen.Due to the arrangement of the connecting device in the storage box, sufficient corrosion protection of the connecting device and the sections of the tension rods protruding into the storage box can be ensured in a simple manner. Additional corrosion protection is not necessary.
Die Zugstäbe sind dazu vorgesehen, Kräfte in den Beton der Bauwerksteile einzuleiten. Die hierfür benötigte Länge der Zugstäbe wird anhand der zu übertragenden Kräfte berechnet. Für die Berechnung der Länge der Zugstäbe können nur die Abschnitte der Zugstäbe voll berücksichtigt werden, die gut in Beton ausreichender Festigkeit eingebettet sind. Im Falle eines nachträglichen Verfüllens von Aussparungen mit Vergussmasse kann die Festigkeit der Vergussmasse und deren Verbindung mit den Zugstäben häufig nicht in ausreichendem Maße gewährleistet werden, so dass in den Aussparungen verlaufende Zugstababschnitte nicht oder nicht in gleichem Maße in die Berechnung einfließen können wie Zugstababschnitte, die in Ortbeton oder in im Fertigteilwerk vergossenen Beton ragen.The tension rods are intended to introduce forces into the concrete of the building parts. The length of the tension rods required for this is calculated based on the forces to be transmitted. When calculating the length of the tension bars, only those sections of the tension bars that are well embedded in concrete of sufficient strength can be fully taken into account. If recesses are subsequently filled with casting compound, the strength of the casting compound and its connection to the tension rods can often not be sufficiently guaranteed, so that tension rod sections running in the recesses cannot be included in the calculation or not to the same extent as tension rod sections protrude into in-situ concrete or into concrete cast in the precast factory.
Dadurch, dass bei der Anordnung der Verbindungseinrichtung im Verwahrkasten die gesamte außerhalb des Verwahrkastens liegende Länge der Zugstäbe bei der Herstellung der Gebäudeteile in das erste bzw. das zweite Gebäudeteil eingebettet werden kann und kein nachträgliches Verfüllen einer Aussparung mit Vergussmasse wie beispielsweise Mörtel erfolgen muss, kann hier die gesamte außerhalb des Verwahrkastens verlaufende Länge der Zugstäbe bei der Berechnung der benötigten Länge der Zugstäbe, insbesondere bei der Berechnung der Übergreifungslänge, berücksichtigt werden. Dadurch wird eine geringere Länge der Zugstäbe benötigt.The fact that when arranging the connecting device in the storage box, the entire length of the tension rods lying outside the storage box can be embedded in the first or second building part during the production of the building parts and no subsequent filling of a recess with casting compound such as mortar has to be done Here, the entire length of the tension rods running outside the storage box must be taken into account when calculating the required length of the tension rods, in particular when calculating the overlap length. This means that a shorter length of the tension rods is required.
Vorteilhaft sind die ersten Zugstäbe und die zweiten Zugstäbe in einer gemeinsamen, senkrecht zur Hochrichtung verlaufenden Ebene angeordnet. Dadurch wird eine günstige Krafteinleitung erreicht. Gleichzeitig ist die Verbindung der Zugstäbe in dem Verwahrkasten auf einfache Weise möglich, da kein Höhenversatz zwischen den Zugstäben ausgeglichen werden muss.The first tension rods and the second tension rods are advantageously arranged in a common plane that runs perpendicular to the vertical direction. This results in a favorable application of force. At the same time, the connection of the tension rods in the storage box is possible in a simple manner, since no height offset between the tension rods has to be compensated for.
Besonders vorteilhaft umfasst die Verbindungseinrichtung eine in dem Verwahrkasten angeordnete Verbindungsplatte, an der die ersten Zugstäbe und die zweiten Zugstäbe fixiert sind. In vorteilhafter Ausführungsvariante ist die Verbindungsplatte an einer Längsseite des Verwahrkastens in dem Verwahrkasten angeordnet. Besonders vorteilhaft ist die Verbindungsplatte an der der Balkonplatte näher liegenden Längsseite des Verwahrkastens angeordnet. Bevorzugt sind die im Gebäude eingebetteten, durch die der Balkonplatte entfernt liegende Längsseite des Verwahrkastens ragenden Zugstäbe fest mit der Verbindungsplatte verbunden, beispielsweise über Schweißverbindungen. Bei der Montage der Balkonplatte werden bevorzugt die Zugstäbe der Balkonplatte durch Öffnungen der Verbindungsplatte geschoben und über Schraubverbindungen, bevorzugt über Muttern, fixiert. Hierzu umfasst die Verbindungseinrichtung vorteilhaft mindestens eine Schraubverbindung. Die Öffnungen der Verbindungsplatte sind vorteilhaft so groß bemessen, dass ein Toleranzausgleich zwischen den Zugstäben des Gebäudes und den Zugstäben der Balkonplatte möglich ist.Particularly advantageously, the connecting device comprises a connecting plate arranged in the storage box, to which the first tension rods and the second tension rods are fixed. In an advantageous embodiment variant, the connecting plate is on one Long side of the storage box arranged in the storage box. The connecting plate is particularly advantageously arranged on the long side of the storage box that is closer to the balcony plate. The tension rods embedded in the building and projecting through the long side of the storage box remote from the balcony slab are preferably firmly connected to the connecting plate, for example via welded connections. When assembling the balcony slab, the tension rods of the balcony slab are preferably pushed through openings in the connecting plate and fixed via screw connections, preferably via nuts. For this purpose, the connecting device advantageously comprises at least one screw connection. The openings in the connecting plate are advantageously dimensioned so large that tolerance compensation between the tension rods of the building and the tension rods of the balcony slab is possible.
Für eine einfache Montage ist vorteilhaft vorgesehen, dass der Verwahrkasten mindestens eine verschließbare Zugangsöffnung aufweist, über die die Verbindungseinrichtung zugänglich ist. Besonders bevorzugt ist die Zugangsöffnung wiederverschließbar ausgebildet, so dass die Verbindungseinrichtung nach der Montage durch erneutes Öffnen des Verwahrkastens wieder zugänglich ist.For easy assembly, it is advantageously provided that the storage box has at least one closable access opening through which the connecting device is accessible. Particularly preferably, the access opening is designed to be reclosable, so that the connecting device is accessible again after assembly by reopening the storage box.
Eine einfache Gestaltung ergibt sich, wenn die Zugangsöffnung sich über die gesamte Länge und die gesamte Breite des Verwahrkastens erstreckt. Es kann jedoch auch vorgesehen sein, dass die Zugangsöffnung sich lediglich über den die Verbindungseinrichtung überdeckenden Bereich des Verwahrkastens erstreckt. In alternativer Gestaltung kann sich die Zugangsöffnung lediglich über den Bereich der Gewindeverbindungen erstrecken. Es kann auch vorgesehen sein, dass der Verwahrkasten mehrere Zugangsöffnungen aufweist, über die jeweils eine oder mehrere Gewindeverbindungen zugänglich sind.A simple design results when the access opening extends over the entire length and the entire width of the storage box. However, it can also be provided that the access opening only extends over the area of the storage box that covers the connecting device. In an alternative design, the access opening can only extend over the area of the threaded connections. It can also be provided that the storage box has several access openings, through which one or more threaded connections are accessible.
Bevorzugt ist der Verwahrkasten mit Mineralwolle als Isoliermaterial gefüllt. Vorteilhaft wird das Isoliermaterial zumindest teilweise eingebracht, nachdem die ersten und zweiten Zugstäbe in dem Verwahrkasten miteinander verbunden wurden. Eine einfache Gestaltung ergibt sich, wenn der Verwahrkasten aus Kunststoff ausgebildet ist. Besonders bevorzugt ist der Verwahrkasten aus Strangpressprofilen hergestellt. Dadurch ist eine einfache und wirtschaftliche Herstellung des Verwahrkastens möglich. Bevorzugt weist der Verwahrkasten einen Grundkörper und mindestens einen mit dem Grundkörper verbindbaren Deckel auf. Der Deckel ist bevorzugt lösbar mit dem Grundkörper verbunden. Der Deckel kann mit dem Grundkörper beispielsweise über eine Schnappverbindung, eine Verrastung oder Klemmung verbunden sein. Auch eine andere Art der Verbindung von Deckel und Grundkörper kann vorteilhaft sein. Es kann alternativ vorgesehen sein, den Deckel mit dem Grundkörper unlösbar zu verbinden, beispielsweise über eine Klebeverbindung.The storage box is preferably filled with mineral wool as insulating material. The insulating material is advantageously introduced at least partially after the first and second tension rods have been connected to one another in the storage box. A simple one Design results when the storage box is made of plastic. The storage box is particularly preferably made from extruded profiles. This makes it possible to produce the storage box easily and economically. The storage box preferably has a base body and at least one lid that can be connected to the base body. The cover is preferably detachably connected to the base body. The cover can be connected to the base body, for example via a snap connection, a latching or clamping. Another type of connection between the cover and the base body can also be advantageous. Alternatively, it can be provided to permanently connect the cover to the base body, for example via an adhesive connection.
Der Verwahrkasten kann an seinen senkrecht zur Längsrichtung liegenden Stirnseiten offen sein. Dies ist insbesondere dann vorteilhaft, wenn mehrere Verwahrkästen stirnseitig aneinander anschließend angeordnet werden. Insbesondere für Verwahrkästen, die die Dämmfuge in Längsrichtung abschließen, ist vorteilhaft vorgesehen, dass der Verwahrkasten an mindestens einer Stirnseite geschlossen ist. Hierzu kann ein weiterer Deckel vorgesehen sein. In Querrichtung und in Hochrichtung ist der Verwahrkasten vorteilhaft geschlossen ausgebildet.The storage box can be open on its end faces, which are perpendicular to the longitudinal direction. This is particularly advantageous if several storage boxes are arranged next to one another at the front. Particularly for storage boxes that close off the insulation joint in the longitudinal direction, it is advantageously provided that the storage box is closed on at least one end face. An additional cover can be provided for this purpose. The storage box is advantageously designed to be closed in the transverse direction and in the vertical direction.
Zur Übertragung der Querkräfte ist vorteilhaft an der zweiten Längsseite des Verwahrkastens mindestens eine Auflage für die vertikale Abstützung des zweiten Bauwerksteils angeordnet. Dadurch ist eine einfache nachträgliche Montage des zweiten Bauwerksteils an dem ersten Bauwerksteil möglich. Nachträglich bedeutet dabei, dass das zweite Bauwerksteil, beispielsweise die Balkonplatte, bereits vollständig hergestellt und die Zugstäbe in die Balkonplatte eingebettet sind, bevor die Balkonplatte an dem ersten Bauwerksteil fixiert wird. Dadurch ist eine einfache und wirtschaftliche Erstellung des Gebäudes möglich. Kranzeiten können durch diese Art der Herstellung minimiert werden.To transmit the transverse forces, at least one support for the vertical support of the second structural part is advantageously arranged on the second longitudinal side of the storage box. This makes it possible to easily subsequently assemble the second structural part on the first structural part. Subsequently means that the second structural part, for example the balcony slab, is already completely manufactured and the tension rods are embedded in the balcony slab before the balcony slab is fixed to the first structural part. This allows the building to be constructed easily and economically. Crane times can be minimized through this type of manufacturing.
Vorteilhaft ragt mindestens ein Querkraftstab durch den Verwahrkasten. In bevorzugter Gestaltung ist der mindestens ein Querkraftstab an der Auflage für die vertikale Abstützung des zweiten Bauwerksteils fixiert. Auch eine andere Anbindung des Querkraftstabs kann jedoch vorteilhaft sein.At least one shear force bar advantageously protrudes through the storage box. In a preferred design, the at least one transverse force bar is fixed to the support for the vertical support of the second structural part. However, a different connection of the shear force bar can also be advantageous.
