Definitions

  • the invention relates to a device for force-transmitting connection of a first load-bearing building part, in particular a building wall, to a second load-bearing building part, in particular a stair part, at least comprising a support element extending between the first building part and the second building part, the support element being at least in a first longitudinal section has a first force application area associated with the first building part and a second force application area associated with the second building part at least in a second longitudinal section spaced apart from the first longitudinal section in the longitudinal direction (x) of the support element.
  • Such connecting devices are often formed by a support element in the form of a shear force mandrel, which extends between two parts of the building and is often arranged in a sleeve at least on one side for this purpose, in order to be able to absorb or transmit shear forces and bending moments, and in the longitudinal direction (x), i.e to allow relative movements between the two parts of the building without resistance in its axial direction.

  • profile carriers for example tubular rectangular hollow profiles or I-beams
  • I-beams which are used in particular when higher bending moments are to be transmitted, for example due to a larger distance between the two parts of the building and the associated larger lever arm.
  • An example of such a rectangular hollow profile is in WO 2012/084327 disclosed.
  • the round mandrels usually used are primarily suitable for transmitting higher transverse forces, but are only able to transmit lower bending moments.
  • a difference between support elements made of round mandrels on the one hand and rectangular hollow profiles or I-beams on the other hand is that rectangular hollow profiles, I-beams and other support elements with a cross-section deviating from a circle must be installed in the correct position, i.e. with a force application surface which must not have any inclination to the horizontal, otherwise the force will not be applied over the entire area provided for this purpose, but only over a part of it.
  • This can quickly lead to uneven, off-center or excessive loading of the force-bearing areas, such as in the case of elastomeric bearings, which are commonly used in such connection devices for impact sound insulation. If these are not loaded according to their design, but only in a partial area and/or unevenly, then their compression and thus usually their rigidity increases significantly and they can no longer guarantee the sound insulation they expect.
  • the force is introduced independently of any twisting of the mandrel about its longitudinal axis over a force introduction area that is always the same, so that such round mandrel connections are sometimes preferred where they would not be preferred at all due to their load-bearing behavior.
  • Round mandrels are also often used where there are space problems during installation, since the round mandrels have a smaller overall cross-section than hollow profile elements or I-beams with the same shear force carrying capacity.
  • An example of such an application with cramped installation conditions are spiral staircases, in which the flight of stairs has to be supported in the adjacent building wall and rectangular hollow profiles in alignments with an exactly horizontal force application surface would increase the component thickness of the inclined flight of stairs for geometric reasons, since the rectangular hollow profile is not in one of the flight of stairs corresponding inclination, but only horizontally, i.e. twisted to the inclination of the flight of stairs. Due to this inclined position of the hollow profile relative to the flight of stairs, the diagonal edges of the hollow profile migrate close to the top and bottom of the flight of stairs and require a greater concrete cover and thus a greater component thickness of the corresponding part of the building.
  • the object of the present invention is now to provide a device for force-transmitting connection of the type mentioned at the outset, which combines the properties of both variants of carrier elements described and is characterized above all by the fact that, on the one hand, it has a Allows installation with error tolerance, as is the case with round mandrels, and on the other hand uses support elements that are able to transmit larger bending moments than comparably dimensioned round mandrels.
  • the support element has a force transmission element in at least one of the two force application areas and/or interacts with a force transmission element
  • the support element consists of a profile body with at least two profile webs extending in the longitudinal direction, at least in one of the two force application areas
  • the force transmission element has a first force application surface
  • the force introduction surface has an at least partially arcuate surface curvature in a cross-sectional plane extending orthogonally to the longitudinal direction (x) of the carrier element.
  • the force transmission element is arranged on the underside of the carrier element and the force transmission surface of the force transmission element is also arranged on the underside of the force transmission element.
  • the carrier element does not consist of the usual round mandrels or other solid material with a cross section deviating from a circle, but of a profile body with at least two profile webs, which already results in a significant improvement in the absorption or transmission of bending moments can be achieved.
  • the carrier element also has a force transmission element with a circular surface curvature, thus forming a force application surface with a circular-cylindrical surface that corresponds to the force application surface of round mandrels, which is precisely responsible for the fact that with round mandrels there is also an opposite to the longitudinal axis of the Support element twisted installation is possible and without negative effects in terms of load-bearing behavior.
  • the carrier element actually represents a combination of the advantages of both known carrier element variants and thus enables the carrier element to be installed in an orientation that can also be twisted about the longitudinal axis, without this twisting changing the size of the force application area and thus the load .
  • a carrier element consisting of a profile body in, for example, spiral staircases with an inclined flight of stairs and to adapt the profile body to the inclination here and thereby again not to affect the component height.
  • the force is introduced via the circular arc-shaped force introduction surface, which is just as large as in the case of non-twisted installation, i.e. installation with an exactly horizontal alignment, as is necessary with such profile bodies.
  • connection device thus fulfills its task and the load-bearing behavior required of it even with imprecise installation, in this respect corresponds to the usual round mandrels, but has a correspondingly superior structure and improved load-bearing properties due to the design of the carrier element as a profile body.
  • the at least two profile webs of the carrier element extending in the longitudinal direction extend parallel to one another, as is the case, for example, with an I-beam or also with a rectangular hollow profile.
  • the at least two longitudinally extending profile webs of the support element are arranged at an angle, in particular at right angles to one another, as is the case with a T-beam, for example, and which is particularly important for the load-bearing behavior.
  • the carrier element has at least one further profile web which extends in the longitudinal direction and is arranged parallel or at an angle to one of the other profile webs.
  • at least three profile webs particularly suitable rigid profile bodies can be formed, such as an I-beam or a rectangular hollow profile.
  • the carrier element consists, at least in sections, of a hollow profile body, in particular with a rectangular cross section, or of an I-profile body.
  • these profile shapes nevertheless enable high resilience and, in particular, flexural rigidity, which also represent an essential criterion in connection devices of this type.
  • the power transmission element As far as the power transmission element is concerned, it is recommended that this is fixed to the carrier element, in particular in a non-positive, material and/or form-fitting manner and particularly preferably via a welded connection.
  • the force transmission element should not only transmit forces between the carrier element and the associated part of the building, but it should also not perform any movements relative to the carrier element, at least not when it is arranged on the carrier element. In this case, the force-transmitting element and the carrier element should form a fixed unit and the relative movements should still be possible between the force-transmitting element and the associated part of the building.
  • the force transmission element is not assigned to the carrier element, but to the building part, as can be the case, for example, when the carrier element is positioned in a trough that has the force transmission element and interacts with the building part, then the force transmission element must be fixed at least at the named Tub done, which should indeed be assigned to the part of the building. And in this case, in turn, the trough would be non-positively, materially and/or positively fixed to the carrier element, but not the power transmission element itself.
  • the other of the two force application areas it is in principle possible for the other of the two force application areas to also have a similar force application surface with a circular arc surface curvature and/or to carry a force transmission element which has such a force transmission surface with a circular arc surface curvature; However, this is not necessary in many cases, since it is already sufficient for the desired flexibility and error tolerance during installation, if only one of the two force application areas has a force application surface with an arcuate surface curvature.
  • the other of the two force introduction regions has a second force introduction surface with a cross-sectional plane extending horizontally to the longitudinal direction of the carrier element that at least partially deviates from the shape of a circular arc, with this curve having in particular a curvature of approximately 0 .
  • the second force application surface can advantageously consist of a surface of one of the profile webs, so that no additional force transmission element is required.
  • the carrier element according to the invention can consist, for example, of a profile body extending over the entire length of the carrier element and having the force transmission element essential to the invention only in the area of one of the two force introduction regions and/or interacting with the force transmission element according to the invention, which has the arcuate surface curvature essential to the invention in the area of its force application surface.
  • the force transmission element is missing, with the profile body itself having the force application surface for the associated building part there.
  • This first force application surface is advantageously convex and/or in the form of a segment of a circular cylinder jacket surface, i.e. it corresponds more or less to the segment of a round mandrel of the prior art, which is formed onto the hollow profile in the longitudinal section of the corresponding force application area.
  • the arcuate surface curvature of the first force application surface is designed in this way that the center of their radius of curvature is at least approximately in the area of the center of gravity of the carrier element in this cross-sectional plane extending orthogonally to the longitudinal direction of the carrier element. This ensures that even when the carrier element is rotated or inclined to the longitudinal axis of the carrier element, its forces act in the vertical direction and are transmitted free of lateral forces from the carrier element and the cylindrical force application surface to the associated part of the building.
  • the longitudinal axis of the lateral cylinder surface of the force transmission element and the central/longitudinal axis of the carrier element coincide or run parallel to one another with only a small mutual distance.
  • the force transmission element is arranged on the underside of the carrier element in the installed state and the force transmission surface of the force transmission element is also arranged on the underside of the force transmission element, so that the force transmission element is arranged in the first force application area assigned to the first load-bearing part of the building, i.e. serves to transmit the forces and moments transmitted from the second supporting part of the building via the support element to the first supporting part of the building.
  • a force distribution means in particular a load distribution plate, is arranged between the force transmission element and the assigned part of the building, which serves to absorb the forces introduced via the segment of a cylinder jacket surface and to distribute them over a correspondingly much larger surface and then to pass them on to the assigned part of the building with a correspondingly reduced force per surface section .
  • the carrier element interacts with a vibration decoupling element, in particular with an impact sound insulation element, which can consist of an insulation material and in particular an elastomer.
  • an impact sound insulation element which can consist of an insulation material and in particular an elastomer.
  • the advantages that are essential to the invention also come into play, in that despite an inclined or inherently incorrect installation of the support element, not only a small lateral partial area of the footfall sound insulation element has to take on the load, as would otherwise be necessary, but also the force is always introduced via the same cylinder surface and via the said load distribution plate, So a force distribution means can be transferred to the entire surface of the impact sound insulation element, so the elastomer bearing.
  • the present invention thus ensures that force is always introduced in the same way and evenly in the area of an impact sound insulation element, and thus ensures optimized insulation behavior.
  • the carrier element allows a relative movement between the curved force application surface of the force transmission element and the associated part of the building or the force distribution means arranged between them, at least during installation, in order to enable corrections in the event of an imprecise installation position. It is particularly advantageous in this connection if these relative movements remain possible even after the installation of the carrier element, ie the error corrections can also be carried out later.
  • the carrier element is movably arranged in the assigned part of the building, ie the curved force introduction surface of the force transmission element and the assigned part of the building or the force distribution means arranged between them are arranged movably with respect to one another.
  • the movement is expediently about the axis of curvature, ie in particular the cylinder axis of the curved force application surface of the force transmission element as a swivel or rolling motion.

  • the stair part according to figure 1 consists of a flight of stairs of a spiral staircase, which is made of concrete and is supported by various structural measures, for example at the upper end of the flight of stairs in area 4.
  • One of these measures also consists of the connecting device 1 according to the invention, which is shown schematically in figure 2 is shown and consists of a carrier element 5 in the form of a rectangular hollow profile body, which carrier element 5 - possibly with the interposition of an in figure 2 barrel sleeve, not shown - extends between the supported part of the building 2 and the supporting part of the building 3, so in the present example of the building wall.
  • the portion of the support element 5 that extends in the supported building part 2 is shown with dashed lines, and the portion that protrudes in comparison and is associated with the supporting building part 3 is shown with solid lines.
  • the trough-shaped recess body 7 is built into the supporting building wall 3 with the most horizontal orientation possible in order to absorb and transmit the forces as evenly as possible. Is now between the support member 5 and the recess body 7 an inclination or rotation about the longitudinal axis of the support member 5 can be determined, mainly because the support member 5 in the supported part of the building 2 is possibly inclined or twisted, as is the case, for example, due to the inclined flight of stairs, this twisted or inclined orientation of the support element 5 in relation to the recess body 7 has no effect, as will be described in more detail below: As in figure 2 is indicated schematically and especially in detail from the Figures 3 - 6 As can be seen, the trough-shaped recess body 7 has a thin load distribution plate 8 which acts as a force distribution means and interacts with a vibration decoupling element 9 arranged below it in the form of an elastomer bearing.
  • the load distribution plate 8 In order to load the elastomer bearing as evenly as possible, it is important that the load distribution plate 8 is oriented or installed as horizontally as possible and that it is loaded centrally, so that the force can then be transmitted evenly over the entire force application area when there is a corresponding force acting on the load distribution plate.
  • connection device is off figure 2 without the supported building part, but with the recess body 7 and the load distribution plate 8 arranged therein as well as the vibration decoupling element 9 positioned underneath and thus clearly shows the rectangular hollow profile body of the carrier element 5, which has four profile webs 5a, 5b, 5c, 5d corresponding to the rectangular shape, of which the profile webs 5a and 5c are arranged parallel to one another and the profile webs 5b and 5d at right angles thereto, but also parallel to one another. All four profile webs extend in the longitudinal direction x of the support element 5 from the first load-bearing part of the building 3 to the second load-bearing part of the building 2.
  • figure 4 also clearly shows the rectangular shape of the profile body 5, the load distribution plate 8, the vibration decoupling element 9 and the trough-shaped recess body 7 surrounding the carrier element 5, the load distribution plate 8 and the vibration decoupling element 9 in a front view.
  • an intermediate space is shown, which, however, only consists of a not between load distribution plate 8 and vibration decoupling element 9, but in the front view in figure 4 in front of this running connecting web 7b of the recess body 7 consists.
  • two cuts AA (vertical cut) and BB (horizontal section) drawn in the Figures 5 and 6 are shown.

  • Force application areas 11 (at x 1 ) and 12 (at x 2 ) are located in these longitudinal sections x 1 , x 2 .
  • a force transmission element 13 is arranged in the force introduction area 11, namely on the underside of the carrier element 5 adjacent to the lower profile web 5a.
  • the power transmission element 13 is - as you mainly from figure 4 can be seen from a segment of a cylinder formed with a circular arc-shaped surface curvature on its underside, which forms a force application surface 13a and an uncurved, flat upper surface 13b with which the force transmission element 13 rests on the profile web 5a of the carrier element 5 and is welded to it there.
  • the force transmission element acts on the load distribution plate 8 in a very narrow, almost linear area, the contact area between the arcuate curvature 13a and the flat, uncurved surface of the load distribution plate 8 (see Fig figure 4 ), from which the force is transmitted to the underlying vibration decoupling element 9.
  • the trough-shaped recess body 7 has an opening 17, which accommodates the carrier element 5 and for this purpose has an almost circular-cylindrical sleeve-like shape, which is adapted to the dimensions of the carrier element 5 and here also a rotation of the carrier element 5 about its longitudinal axis X not disabled.
  • figure 7 is now schematically the carrier element 5 from the Figures 2 to 6 shown with a welded-on power transmission element 13, a disk-shaped load distribution plate 8 arranged underneath it, and a cuboid vibration decoupling element 9 arranged underneath the load distribution plate 8.
  • Figure 8b shows the carrier element with the welded-on force transmission element 13 in the non-twisted neutral position, in which the plane 5e passing through the central axis X of the carrier element 5, which extends parallel to the profile webs 5a, 5c, which are arranged wider than the other two profile webs 5b and 5d, extends, is arranged parallel to the upper side 8a of the load distribution plate 8, in contrast to this Figure 8b a position of the carrier element 5 rotated by an angle ⁇ is shown, in which said plane 5e, which extends parallel to the profile webs 5a, 5c, is arranged at an angle ⁇ with respect to the upper side 8a of the load distribution plate 8.
  • This angle ⁇ corresponds to the maximum inclination of the carrier element since the torsion about the longitudinal axis X is limited by the edge between the profile webs 5a and 5b coming into contact with the surface 8a of the load distribution plate 8 at this maximum inclination.
  • Figure 9b corresponds to the embodiment Figure 8b with the only difference that now in a carrier element 25 shown there instead of the force transmission element 13 an alternative force transmission element 23 was used, which has a larger radius of curvature than the force transmission element 13 from the Figures 2 to 8 .
  • the consequence of this larger radius is that said edge between the profile webs 5a and 5b no longer impedes the rotational movement of the carrier element 25, but is covered by the force transmission element 23, resulting in a larger maximum angle of rotation ⁇ .

Description

Die Erfindung betrifft eine Vorrichtung zum kraftübertragenden Verbinden eines ersten tragenden Gebäudeteils, insbesondere einer Gebäudewand, mit einem zweiten getragenen Gebäudeteil, insbesondere einem Treppenteil, zumindest umfassend ein sich zwischen dem ersten Gebäudeteil und dem zweiten Gebäudeteil erstreckendes Trägerelement, wobei das Trägerelement zumindest in einem ersten Längsabschnitt einen dem ersten Gebäudeteil zugeordneten ersten Krafteinleitungsbereich sowie zumindest in einem vom ersten Längsabschnitt in Längsrichtung (x) des Trägerelements beabstandeten zweiten Längsabschnitt einen dem zweiten Gebäudeteil zugeordneten zweiten Krafteinleitungsbereich aufweist.The invention relates to a device for force-transmitting connection of a first load-bearing building part, in particular a building wall, to a second load-bearing building part, in particular a stair part, at least comprising a support element extending between the first building part and the second building part, the support element being at least in a first longitudinal section has a first force application area associated with the first building part and a second force application area associated with the second building part at least in a second longitudinal section spaced apart from the first longitudinal section in the longitudinal direction (x) of the support element.

Im Stand der Technik gibt es verschiedene Ausführungen solcher Verbindungsvorrichtungen mit auch unterschiedlichen Aufbauten, Einsatzzwecken und Funktionen. So werden derartige Verbindungsvorrichtungen oft durch ein Trägerelement in Form eines Querkraftdorns gebildet, welcher sich zwischen zwei Gebäudeteilen erstreckt und hierzu häufig zumindest einseitig in einer Hülse angeordnet ist, um Querkräfte wie auch Biegemomente aufnehmen beziehungsweise übertragen zu können und dabei in Längsrichtung (x), also in seiner Axialrichtung Relativbewegungen zwischen beiden Gebäudeteilen widerstandsfrei zuzulassen.In the prior art, there are various designs of such connecting devices, also with different structures, purposes and functions. Such connecting devices are often formed by a support element in the form of a shear force mandrel, which extends between two parts of the building and is often arranged in a sleeve at least on one side for this purpose, in order to be able to absorb or transmit shear forces and bending moments, and in the longitudinal direction (x), i.e to allow relative movements between the two parts of the building without resistance in its axial direction.

Die anderen bekannten Trägerelemente bestehen aus Profilträgern, beispielsweise aus rohrartigen Rechteckhohlprofilen oder I-Trägern, welche insbesondere dann zum Einsatz kommen, wenn höhere Biegemomente zu übertragen sind, beispielsweise aufgrund eines größeren Abstands beider Gebäudeteile und eines damit einhergehenden größeren Hebelarms. Ein Beispiel eines solchen Rechteckhohlprofils ist in der WO 2012/084327 offenbart. Im Gegensatz zu den Profilträgern mit eckigen Querschnitten sind die üblicherweise verwendeten Runddorne vor allem zur Übertragung höherer Querkräfte geeignet, jedoch nur dazu in der Lage, geringere Biegemomente zu übertragen.The other known carrier elements consist of profile carriers, for example tubular rectangular hollow profiles or I-beams, which are used in particular when higher bending moments are to be transmitted, for example due to a larger distance between the two parts of the building and the associated larger lever arm. An example of such a rectangular hollow profile is in WO 2012/084327 disclosed. In contrast to the profile beams with angular cross-sections, the round mandrels usually used are primarily suitable for transmitting higher transverse forces, but are only able to transmit lower bending moments.

Ein Unterschied zwischen Trägerelementen aus Runddornen einerseits und aus Rechteckhohlprofilen bzw. I-Trägern andererseits besteht darin, dass Rechteckhohlprofile, I-Träger und sonstige Trägerelemente mit einem von einem Kreis abweichenden Querschnitt positions- und lagegenau eingebaut werden müssen, das heißt, mit einer Krafteinleitungsfläche, die keine Neigung gegenüber der Horizontalen aufweisen darf, da ansonsten die Krafteinleitung nicht über die gesamte dafür vorgesehene Fläche erfolgen wird, sondern nur über einen Teilbereich davon. Dies kann schnell zu ungleichmäßigen, ausmittigen oder überhöhten Belastungen der die Kraft aufnehmenden Bereiche führen, wie zum Beispiel im Falle von Elastomerlagern, die bei solchen Verbindungsvorrichtungen üblicherweise zur Trittschalldämmung verwendet werden. Werden diese nicht entsprechend ihrer Auslegung belastet, sondern nur in einem Teilbereich und/oder ungleichmäßig, so nimmt ihre Kompression und damit in der Regel auch ihre Steifigkeit deutlich zu und sie können nicht mehr die von ihnen erwartete Schalldämmung gewährleisten.A difference between support elements made of round mandrels on the one hand and rectangular hollow profiles or I-beams on the other hand is that rectangular hollow profiles, I-beams and other support elements with a cross-section deviating from a circle must be installed in the correct position, i.e. with a force application surface which must not have any inclination to the horizontal, otherwise the force will not be applied over the entire area provided for this purpose, but only over a part of it. This can quickly lead to uneven, off-center or excessive loading of the force-bearing areas, such as in the case of elastomeric bearings, which are commonly used in such connection devices for impact sound insulation. If these are not loaded according to their design, but only in a partial area and/or unevenly, then their compression and thus usually their rigidity increases significantly and they can no longer guarantee the sound insulation they expect.

Das heißt, ist ein Trägerelement aus einem Rechteckhohlprofil bereits um Winkel von wenigen Grad verschwenkt um seine Längsachse eingebaut, so erfolgt die Krafteinleitung vom Trägerelement in das ihm zugeordnete Gebäudeteil bzw. umgekehrt vom ihm zugeordneten Gebäudeteil in das Trägerelement nicht über die Gesamtgrundfläche des Rechteckhohlprofils, sondern nur über einen Teilbereich, im Extremfall nur über die die beim Verschwenken um die Längsachse dem zugeordnetem Gebäudeteil zugewandte Hohlprofilkante.This means that if a carrier element made of a rectangular hollow profile is already installed and pivoted by a few degrees about its longitudinal axis, the introduction of force from the carrier element into the part of the building assigned to it or vice versa from the part of the building assigned to it into the carrier element does not take place over the entire base area of the rectangular hollow profile, but instead only over a partial area, in extreme cases only over the edge of the hollow profile facing the associated part of the building when pivoting about the longitudinal axis.

Bei Runddornen hingegen erfolgt die Krafteinleitung unabhängig von einer Verdrehung des Dorns um seine Längsachse über einen immer gleichen Krafteinleitungsbereich, so dass solche Runddornverbindungen manchmal auch dort bevorzugt eingesetzt werden, wo sie aufgrund ihres Tragverhaltens an sich gar nicht bevorzugt wären. Dies muss man dann oft dadurch erkaufen, dass beispielsweise zur Übertragung von großen Biegemomenten, die an sich für auf die vorliegenden Querkräfte abgestimmten Runddorne zu groß wären, die Anzahl oder der Durchmesser der Runddorne erhöht und damit die Gesamtkosten der für den jeweiligen Anwendungsfall benötigten Verbindungsvorrichtung entsprechend vergrößert werden.In the case of round mandrels, on the other hand, the force is introduced independently of any twisting of the mandrel about its longitudinal axis over a force introduction area that is always the same, so that such round mandrel connections are sometimes preferred where they would not be preferred at all due to their load-bearing behavior. This often has to be bought at the cost of, for example, increasing the number or the diameter of the round mandrels in order to transmit large bending moments, which would be too great for round mandrels tailored to the transverse forces present, and thus the overall costs of the connecting device required for the respective application are increased accordingly be enlarged.

Runddorne kommen auch häufig dort zum Einsatz, wo es Platzprobleme beim Einbau gibt, da die Runddorne insgesamt einen kleineren Querschnitt aufweisen als Hohlprofilelemente oder I-Träger mit derselben Querkrafttragfähigkeit. Ein Beispiel für einen derartigen Einsatzfall mit beengten Einbauverhältnissen bilden Wendeltreppen, bei denen der Treppenlauf in der benachbarten Gebäudewand aufgelagert werden muss und Rechteckhohlprofile bei Ausrichtungen mit exakt horizontaler Krafteinleitungsfläche die Bauteildicke des geneigten Treppenlaufes aus geometrischen Gründen vergrößern würden, da das Rechteckhohlprofil nicht in einer dem Treppenlauf entsprechenden Neigung eingebaut werden kann, sondern nur horizontal, d.h. verdreht zur Neigung des Treppenlaufs. Durch diese Schrägstellung des Hohlprofils relativ zum Treppenlauf wandern die diagonalen Kanten des Hohlprofils nahe an die Oberseite und Unterseite des Treppenlaufs und machen eine größere Betonüberdeckung und damit eine größere Bauteildicke des entsprechenden Gebäudeteils erforderlich.Round mandrels are also often used where there are space problems during installation, since the round mandrels have a smaller overall cross-section than hollow profile elements or I-beams with the same shear force carrying capacity. An example of such an application with cramped installation conditions are spiral staircases, in which the flight of stairs has to be supported in the adjacent building wall and rectangular hollow profiles in alignments with an exactly horizontal force application surface would increase the component thickness of the inclined flight of stairs for geometric reasons, since the rectangular hollow profile is not in one of the flight of stairs corresponding inclination, but only horizontally, i.e. twisted to the inclination of the flight of stairs. Due to this inclined position of the hollow profile relative to the flight of stairs, the diagonal edges of the hollow profile migrate close to the top and bottom of the flight of stairs and require a greater concrete cover and thus a greater component thickness of the corresponding part of the building.

Das heißt also, dass bei einer nicht der Neigung des Treppenlaufs entsprechend eingebauten Orientierung des Rechteckhohlprofils die Dicke des Treppenlaufs vergrößert werden müsste, wenn das Rechteckhohlprofil vorschriftsmäßig also mit exakt horizontal ausgerichteter Krafteinleitungsfläche eingebaut würde. Auch hier besteht bei den geneigten Treppenläufen das Problem, dass Trägerelemente, die aus Rechteckprofilen bestehen, exakt horizontal eingebaut werden müssen, um die Krafteinleitung über die vorgesehene vollständige Grundfläche zu ermöglichen. Um zu verhindern, dass der Treppenlauf in seiner Bauteildicke vergrößert werden muss, werden auch hier oft Runddorne eingesetzt, die hinsichtlich ihrer Orientierung, das heißt Verdrehungen um ihre Längsachse beim Einbau keinen Vorgaben unterworfen sind.This means that if the orientation of the rectangular hollow profile does not correspond to the inclination of the flight of stairs, the thickness of the flight of stairs would have to be increased if the rectangular hollow profile were installed according to the regulations with the force application surface aligned exactly horizontally. Here, too, there is the problem with the sloping flights of stairs that support elements, which consist of rectangular profiles, have to be installed exactly horizontally in order to enable the introduction of force over the planned complete base area. In order to prevent the flight of stairs from having to be increased in its component thickness, round mandrels are often used here as well, which are not subject to any specifications with regard to their orientation, i.e. twisting around their longitudinal axis during installation.

Von diesem Stand der Technik ausgehend liegt der vorliegenden Erfindung nun die Aufgabe zugrunde, eine Vorrichtung zum kraftübertragenden Verbinden der eingangsgenannten Art zur Verfügung zu stellen, die die Eigenschaften beider geschilderten Varianten von Trägerelementen in sich vereint und sich vor allem dadurch auszeichnet, dass sie einerseits einen Einbau mit Fehlertoleranz ermöglicht, wie dies bei Runddornen der Fall ist und andererseits aber Trägerelemente verwendet, die dazu in der Lage sind, größere Biegemomente als vergleichbar dimensionierte Runddorne zu übertragen.Proceeding from this state of the art, the object of the present invention is now to provide a device for force-transmitting connection of the type mentioned at the outset, which combines the properties of both variants of carrier elements described and is characterized above all by the fact that, on the one hand, it has a Allows installation with error tolerance, as is the case with round mandrels, and on the other hand uses support elements that are able to transmit larger bending moments than comparably dimensioned round mandrels.

Diese Aufgabe wird bei einer Vorrichtung der eingangsgenannten Art durch die Merkmale des Anspruchs 1 erfüllt. Demgemäß weist das Trägerelement zumindest in einem der beiden Krafteinleitungsbereiche ein Kraftübertragungselement auf und/oder wirkt mit einem Kraftübertragungselement zusammen, besteht das Trägerelement zumindest in dem einen der beiden Krafteinleitungsbereiche aus einem Profilkörper mit zumindest zwei sich in Längsrichtung erstreckenden Profilstegen, weist das Kraftübertragungselement eine erste Krafteinleitungsfläche auf und weist die Krafteinleitungsfläche in einer sich orthogonal zur Längsrichtung (x) des Trägerelements erstreckenden Querschnittsebene eine zumindest teilweise kreisbogenförmige Oberflächenkrümmung auf. Schließlich ist das Kraftübertragungselement auf der Unterseite des Trägerelements angeordnet und ist auch die Kraftübertragungsfläche des Kraftübertragungselements auf der Unterseite des Kraftübertragungselements angeordnet.This object is achieved by the features of claim 1 in a device of the type mentioned. Accordingly, the support element has a force transmission element in at least one of the two force application areas and/or interacts with a force transmission element, the support element consists of a profile body with at least two profile webs extending in the longitudinal direction, at least in one of the two force application areas, the force transmission element has a first force application surface and the force introduction surface has an at least partially arcuate surface curvature in a cross-sectional plane extending orthogonally to the longitudinal direction (x) of the carrier element. Finally, the force transmission element is arranged on the underside of the carrier element and the force transmission surface of the force transmission element is also arranged on the underside of the force transmission element.

Weitere erfindungswesentliche Merkmale sind in den Unteransprüchen aufgeführt, deren Inhalt hier zur Vermeidung von Wiederholungen ausdrücklich einbezogen wird.Further features essential to the invention are listed in the dependent claims, the content of which is expressly included here to avoid repetition.

Wesentlich am Gegenstand der vorliegenden Erfindung ist nun, dass das Trägerelement nicht aus den üblichen Runddornen oder anderem Vollmaterial mit von einem Kreis abweichendem Querschnitt besteht, sondern aus einem Profilkörper mit zumindest zwei Profilstegen, wodurch sich bereits eine deutliche Verbesserung der Aufnahme bzw. der Übertragung von Biegemomenten erzielen lässt. Darüber hinaus weist das Trägerelement zusätzlich zu den Profilstegen aber auch ein Kraftübertragungselement auf mit einer kreisbogenförmigen Oberflächenkrümmung, bildet somit eine Krafteinleitungsfläche mit kreiszylinderförmiger Oberfläche, die der Krafteinleitungsfläche von Runddornen entspricht, welche ja gerade dafür verantwortlich ist, dass bei Runddornen auch ein gegenüber der Längsachse des Trägerelements verdrehter Einbau möglich und ohne negative Auswirkungen hinsichtlich des Tragverhaltens ist.What is essential about the subject matter of the present invention is that the carrier element does not consist of the usual round mandrels or other solid material with a cross section deviating from a circle, but of a profile body with at least two profile webs, which already results in a significant improvement in the absorption or transmission of bending moments can be achieved. In addition to the profile webs, the carrier element also has a force transmission element with a circular surface curvature, thus forming a force application surface with a circular-cylindrical surface that corresponds to the force application surface of round mandrels, which is precisely responsible for the fact that with round mandrels there is also an opposite to the longitudinal axis of the Support element twisted installation is possible and without negative effects in terms of load-bearing behavior.

Somit stellt bei der vorliegenden Verbindungsvorrichtung tatsächlich das Trägerelement eine Kombination der Vorteile beider bekannter Trägerelementvarianten dar und ermöglicht somit einen Einbau des Trägerelements in einer Orientierung, die auch verdreht um die Längsachse sein kann, ohne dass diese Verdrehung die Größe der Krafteinleitungsfläche und damit die Belastung verändert. Damit ist es nun sogar möglich, ein aus einem Profilkörper bestehendes Trägerelement bei zum Beispiel Wendeltreppen mit geneigtem Treppenlauf einzubauen und hier den Profilkörper an die Neigung anzupassen und dadurch wiederum die Bauteilhöhe nicht zu beeinträchtigen. Trotz dieses geneigten Einbaus erfolgt die Krafteinleitung über die kreisbogenförmige Krafteinleitungsfläche, die genauso groß ausfällt wie im Fall mit unverdrehtem Einbau, also einem Einbau mit exakt horizontaler Ausrichtung, wie es an sich bei solchen Profilkörpern erforderlich ist.Thus, in the present connection device, the carrier element actually represents a combination of the advantages of both known carrier element variants and thus enables the carrier element to be installed in an orientation that can also be twisted about the longitudinal axis, without this twisting changing the size of the force application area and thus the load . It is now even possible to install a carrier element consisting of a profile body in, for example, spiral staircases with an inclined flight of stairs and to adapt the profile body to the inclination here and thereby again not to affect the component height. Despite this inclined installation, the force is introduced via the circular arc-shaped force introduction surface, which is just as large as in the case of non-twisted installation, i.e. installation with an exactly horizontal alignment, as is necessary with such profile bodies.

Die erfindungsgemäße Verbindungsvorrichtung erfüllt somit ihre Aufgabe und das von ihr geforderte Tragverhalten auch bei einem ungenauen Einbau, entspricht insofern den üblichen Runddornen, weist jedoch aufgrund der Ausgestaltung des Trägerelements als Profilkörper einen demgemäß überlegenen Aufbau und verbesserte Tragfähigkeitseigenschaften auf.The connection device according to the invention thus fulfills its task and the load-bearing behavior required of it even with imprecise installation, in this respect corresponds to the usual round mandrels, but has a correspondingly superior structure and improved load-bearing properties due to the design of the carrier element as a profile body.

Hinsichtlich der Ausgestaltung des Trägerelements als Profilkörper gibt es verschiedene Möglichkeiten mit unterschiedlichen Eigenschaften und Vorteilen. So ist zum einen vorgesehen, dass sich die zumindest zwei in Längsrichtungen erstreckenden Profilstege des Trägerelements parallel zueinander erstrecken, wie dies beispielsweise bei einem I-Träger der Fall ist oder auch bei einem Rechteckhohlprofil. Daneben ist es auch vorgesehen, dass sich die zumindest zwei in Längsrichtungen erstreckenden Profilstege des Trägerelements winklig, insbesondere rechtwinklig zueinander angeordnet sind, wie dies beispielsweise bei einem T-Träger der Fall ist und was vor allem für das Tragverhalten wesentlich ist.With regard to the design of the carrier element as a profile body, there are various options with different properties and advantages. On the one hand, it is provided that the at least two profile webs of the carrier element extending in the longitudinal direction extend parallel to one another, as is the case, for example, with an I-beam or also with a rectangular hollow profile. In addition, it is also provided that the at least two longitudinally extending profile webs of the support element are arranged at an angle, in particular at right angles to one another, as is the case with a T-beam, for example, and which is particularly important for the load-bearing behavior.

Besonders vorteilhaft in diesem Zusammenhang ist es, wenn das Trägerelement zumindest einen weiteren sich in Längsrichtung erstreckenden Profilsteg aufweist, der zu einem der anderen Profilstege parallel oder winklig angeordnet ist. Mit diesen dann insgesamt mindestens drei Profilstegen lassen sich besonders geeignete biegesteife Profilkörper bilden, wie beispielsweise ein I-Träger oder ein Rechteckhohlprofil.It is particularly advantageous in this connection if the carrier element has at least one further profile web which extends in the longitudinal direction and is arranged parallel or at an angle to one of the other profile webs. With these then at least three profile webs, particularly suitable rigid profile bodies can be formed, such as an I-beam or a rectangular hollow profile.

Insgesamt ist es vorteilhaft, wenn das Trägerelement zumindest abschnittsweise aus einem Hohlprofilkörper mit insbesondere rechteckigem Querschnitt oder aus einem I-Profilkörper besteht. Diese Profilformen ermöglichen bei vergleichsweise geringem Materialeinsatz und somit auch vergleichsweise geringeren Materialkosten eine dennoch große Belastbarkeit und insbesondere Biegesteifigkeit, die bei derartigen Verbindungsvorrichtungen auch ein wesentliches Kriterium darstellen.Overall, it is advantageous if the carrier element consists, at least in sections, of a hollow profile body, in particular with a rectangular cross section, or of an I-profile body. With comparatively little use of material and thus also comparatively lower material costs, these profile shapes nevertheless enable high resilience and, in particular, flexural rigidity, which also represent an essential criterion in connection devices of this type.

Was nun das Kraftübertragungselement betrifft, so empfiehlt es sich, dass dieses an dem Trägerelement festgelegt ist, insbesondere kraft-, stoff- und/oder formschlüssig und besonders bevorzugt über eine Schweißverbindung. Dabei soll das Kraftübertragungselement nicht nur Kräfte zwischen Trägerelement und zugeordnetem Gebäudeteil übertragen, sondern es soll auch keine Relativbewegungen gegenüber dem Trägerelement durchführen, zumindest nicht in dem Fall, in dem es am Trägerelement angeordnet ist. In diesem Fall sollen das Kraftübertragungselement und das Trägerelement eine feste Einheit bilden und die Relativbewegungen dann allenfalls noch zwischen Kraftübertragungselement und zugeordnetem Gebäudeteil möglich sein. In diesem Zusammenhang ist allerdings davon auszugehen, dass trotz der kreisbogenflächigen Oberfläche der Krafteinleitungsfläche, die eine Roll- beziehungsweise eine Wälzbewegung ermöglichen würde, nach dem Einbau eine solche Roll- oder Wälzbewegung nicht mehr stattfindet, diese kreisbogenförmige Oberfläche also lediglich dazu dient, wie bei den Runddornen eine stufenlose Anpassbarkeit der Einbauposition des Trägerelements an das zugeordnete Gebäudeteil beim Einbau bzw. Montieren zu ermöglichen.As far as the power transmission element is concerned, it is recommended that this is fixed to the carrier element, in particular in a non-positive, material and/or form-fitting manner and particularly preferably via a welded connection. The force transmission element should not only transmit forces between the carrier element and the associated part of the building, but it should also not perform any movements relative to the carrier element, at least not when it is arranged on the carrier element. In this case, the force-transmitting element and the carrier element should form a fixed unit and the relative movements should still be possible between the force-transmitting element and the associated part of the building. In this context, however, it can be assumed that despite the arcuate surface of the force application surface, which would enable a rolling or rolling movement, such a rolling or rolling movement no longer takes place after installation, i.e. this arcuate surface is only used, as in the Round mandrels to allow continuous adaptability of the installation position of the support element to the associated part of the building during installation or assembly.

Ist das Kraftübertragungselement nicht dem Trägerelement zugeordnet, sondern dem Gebäudeteil, wie dies beispielsweise dann der Fall sein kann, wenn das Trägerelement in einer Wanne positioniert ist, welche das Kraftübertragungselement aufweist und mit dem Gebäudeteil zusammenwirkt, dann muss die Festlegung des Kraftübertragungselements zumindest an der genannten Wanne erfolgen, die ja dem Gebäudeteil zugeordnet sein soll. Und in diesem Fall wiederum würde die Wanne kraft-, stoff- und/oder formschlüssig am Trägerelement festgelegt sein, nicht jedoch das Kraftübertragungselement selbst.If the force transmission element is not assigned to the carrier element, but to the building part, as can be the case, for example, when the carrier element is positioned in a trough that has the force transmission element and interacts with the building part, then the force transmission element must be fixed at least at the named Tub done, which should indeed be assigned to the part of the building. And in this case, in turn, the trough would be non-positively, materially and/or positively fixed to the carrier element, but not the power transmission element itself.

Es ist zwar grundsätzlich möglich, dass auch der andere der beiden Krafteinleitungsbereiche eine ähnliche Krafteinleitungsfläche mit kreisbogenförmiger Oberflächenkrümmung aufweist und/oder ein Kraftübertragungselement trägt, das eine solche Krafteinleitungsfläche mit kreisbogenförmiger Oberflächenkrümmung aufweist; dies ist jedoch in vielen Fällen nicht erforderlich, da es bereits für die angestrebte Flexibilität und Fehlertoleranz beim Einbau bereits ausreicht, wenn nur an einer der beiden Krafteinleitungsbereiche eine Krafteinleitungsfläche mit kreisbogenförmiger Oberflächenkrümmung vorhanden ist. Vor diesem Hintergrund ist es einfach und zweckmäßig, wenn der andere der beiden Krafteinleitungsbereiche eine zweite Krafteinleitungsfläche mit einem in einer sich horizontal zur Längsrichtung des Trägerelements erstreckenden Querschnittsebene einen zumindest teilweise von einer Kreisbogenform abweichenden Verlauf aufweist, wobei dieser Verlauf insbesondere eine Krümmung von etwa 0 aufweist. In diesem Fall kann vorteilhafterweise die zweite Krafteinleitungsfläche aus einer Oberfläche eines der Profilstege bestehen, so dass kein zusätzliches Kraftübertragungselement erforderlich ist.It is in principle possible for the other of the two force application areas to also have a similar force application surface with a circular arc surface curvature and/or to carry a force transmission element which has such a force transmission surface with a circular arc surface curvature; However, this is not necessary in many cases, since it is already sufficient for the desired flexibility and error tolerance during installation, if only one of the two force application areas has a force application surface with an arcuate surface curvature. Against this background, it is simple and expedient if the other of the two force introduction regions has a second force introduction surface with a cross-sectional plane extending horizontally to the longitudinal direction of the carrier element that at least partially deviates from the shape of a circular arc, with this curve having in particular a curvature of approximately 0 . In this case, the second force application surface can advantageously consist of a surface of one of the profile webs, so that no additional force transmission element is required.

In solch einem Fall kann das erfindungsgemäße Trägerelement beispielsweise daraus bestehen, dass ein Profilkörper sich über die gesamt Länge des Trägerelements erstreckt und lediglich im Bereich des einen der beiden Krafteinleitungsbereiche das erfindungswesentliche Kraftübertragungselement aufweist und/oder mit dem erfindungsgemäßen Kraftübertragungselement zusammenwirkt, welches die erfindungswesentliche kreisbogenförmige Oberflächenkrümmung im Bereich ihrer Krafteinleitungsfläche aufweist. Im Bereich des anderen der beiden Krafteinleitungsbereiche fehlt dann hingegen das Kraftübertragungselement, wobei dort der Profilkörper selbst die Krafteinleitungsfläche für das zugehörige Gebäudeteil aufweist.In such a case, the carrier element according to the invention can consist, for example, of a profile body extending over the entire length of the carrier element and having the force transmission element essential to the invention only in the area of one of the two force introduction regions and/or interacting with the force transmission element according to the invention, which has the arcuate surface curvature essential to the invention in the area of its force application surface. In the area of the other of the two force application areas, on the other hand, the force transmission element is missing, with the profile body itself having the force application surface for the associated building part there.

Diese erste Krafteinleitungsfläche ist vorteilhafterweise konvex und/oder in der Form eines Segments einer Kreiszylindermantelfläche ausgebildet, entspricht also mehr oder weniger dem Segment eines Runddorns des Standes der Technik, welches an das Hohlprofil im Längsabschnitt des entsprechenden Krafteinleitungsbereiches angeformt ist.This first force application surface is advantageously convex and/or in the form of a segment of a circular cylinder jacket surface, i.e. it corresponds more or less to the segment of a round mandrel of the prior art, which is formed onto the hollow profile in the longitudinal section of the corresponding force application area.

Um bei einer Verdrehung des Trägerelements um seine Längsachse keine ausmittigen Kräfte oder eine gleichzeitige Verschiebung der Längsachse zu verursachen, die das System ggf. einseitig belasten oder instabil machen könnten, ist es besonders bevorzugt und zweckmäßig, wenn die kreisbogenförmige Oberflächenkrümmung der ersten Krafteinleitungsfläche derart ausgebildet ist, dass der Mittelpunkt ihres Krümmungsradius zumindest in etwa im Bereich des Flächenschwerpunktes des Trägerelements in dieser sich orthogonal zur Längsrichtung des Trägerelements erstreckenden Querschnittsebene liegt. Dadurch ist sichergestellt, dass selbst bei zur Längsachse des Trägerelements verdreht bzw. geneigt angeordnetem Trägerelement dessen Kräfte in Vertikalrichtung wirken und hierbei frei von Seitenkräften vom Trägerelement und die zylinderförmige Krafteinleitungsfläche auf das zugeordnete Gebäudeteil übertragen werden.In order not to cause eccentric forces or a simultaneous displacement of the longitudinal axis when the carrier element is rotated about its longitudinal axis, which could possibly load the system on one side or make it unstable, it is particularly preferred and expedient if the arcuate surface curvature of the first force application surface is designed in this way that the center of their radius of curvature is at least approximately in the area of the center of gravity of the carrier element in this cross-sectional plane extending orthogonally to the longitudinal direction of the carrier element. This ensures that even when the carrier element is rotated or inclined to the longitudinal axis of the carrier element, its forces act in the vertical direction and are transmitted free of lateral forces from the carrier element and the cylindrical force application surface to the associated part of the building.

In einer besonders bevorzugten symmetrischen Ausführungsform fallen die Längsachse der Zylindermantelfläche des Kraftübertragungselements und die Mittel-/Längsachse des Trägerelements zusammen bzw. verlaufen parallel zueinander mit nur geringem gegenseitigem Abstand.In a particularly preferred symmetrical embodiment, the longitudinal axis of the lateral cylinder surface of the force transmission element and the central/longitudinal axis of the carrier element coincide or run parallel to one another with only a small mutual distance.

Gemäß der vorliegenden Erfindung ist das Kraftübertragungselement im eingebauten Zustand auf der Unterseite des Trägerelements angeordnet und ist auch die Kraftübertragungsfläche des Kraftübertragungselements auf der Unterseite des Kraftübertragungselements angeordnet, so dass das Kraftübertragungselement in dem dem ersten tragenden Gebäudeteil zugeordneten ersten Krafteinleitungsbereich angeordnet ist, also dazu dient, die vom zweiten getragenen Gebäudeteil über das Trägerelement übertragenen Kräfte und Momente auf das erste tragende Gebäudeteils übertragen.According to the present invention, the force transmission element is arranged on the underside of the carrier element in the installed state and the force transmission surface of the force transmission element is also arranged on the underside of the force transmission element, so that the force transmission element is arranged in the first force application area assigned to the first load-bearing part of the building, i.e. serves to transmit the forces and moments transmitted from the second supporting part of the building via the support element to the first supporting part of the building.

Bevorzugt ist zwischen Kraftübertragungselement und zugeordnetem Gebäudeteil ein Kraftverteilungsmittel, insbesondere eine Lastverteilerplatte angeordnet, die dazu dient, die über das Segment einer Zylindermantelfläche eingeleiteten Kräfte aufzunehmen und auf eine demgemäß viel größere Oberfläche zu verteilen und dann mit entsprechend reduzierter Kraft pro Flächenabschnitt auf das zugeordnete Gebäudeteil weiterzugeben.Preferably, a force distribution means, in particular a load distribution plate, is arranged between the force transmission element and the assigned part of the building, which serves to absorb the forces introduced via the segment of a cylinder jacket surface and to distribute them over a correspondingly much larger surface and then to pass them on to the assigned part of the building with a correspondingly reduced force per surface section .

Besonders vorteilhaft ist es nun in diesem Zusammenhang, wenn das Trägerelement mit einem Schwingungsentkopplungselement zusammenwirkt, insbesondere mit einem Trittschalldämmelement, welches aus einem Dämmmaterial und insbesondere aus einem Elastomer bestehen kann. In diesem Fall kommen ebenso die erfindungswesentlichen Vorteile zum Tragen, indem trotz eines geneigten bzw. an sich fehlerhaften Einbaus des Trägerelements dennoch nicht nur ein kleiner seitlicher Teilbereich des Trittschalldämmelements die Belastung übernehmen muss, wie dies ansonsten erforderlich wäre, sondern aufgrund der Zylindermantelfläche des Kraftübertragungselements die Kraft immer über dieselbe Zylinderoberfläche eingeleitet wird und über die genannte Lastverteilerplatte, also ein Kraftverteilungsmittel auf die gesamte Oberfläche des Trittschalldämmelements, also des Elastomerlagers übertragen werden kann. Die vorliegende Erfindung sorgt somit auch im Bereich eines Trittschalldämmelements für eine immer gleichartige und gleichmäßige Krafteinleitung und somit für ein optimiertes Dämmverhalten.In this context, it is particularly advantageous if the carrier element interacts with a vibration decoupling element, in particular with an impact sound insulation element, which can consist of an insulation material and in particular an elastomer. In this case, the advantages that are essential to the invention also come into play, in that despite an inclined or inherently incorrect installation of the support element, not only a small lateral partial area of the footfall sound insulation element has to take on the load, as would otherwise be necessary, but also the force is always introduced via the same cylinder surface and via the said load distribution plate, So a force distribution means can be transferred to the entire surface of the impact sound insulation element, so the elastomer bearing. The present invention thus ensures that force is always introduced in the same way and evenly in the area of an impact sound insulation element, and thus ensures optimized insulation behavior.

Insgesamt ist es vorteilhaft, wenn das Trägerelement zumindest beim Einbau eine Relativbewegung zwischen der gekrümmten Krafteinleitungsfläche des Kraftübertragungselements und dem zugeordneten Gebäudeteil bzw. dem dazwischen angeordneten Kraftverteilungsmittel zulässt, um Korrekturen bei ungenauer Einbaulage zu ermöglichen. Besonders vorteilhaft ist es in diesem Zusammenhang, wenn diese Relativbewegungen auch noch nach dem Einbau des Trägerelements möglich bleiben, also die Fehlerkorrekturen auch noch nachträglich durchgeführt werden können. Hierzu ist es wichtig, dass das Trägerelement beweglich im zugeordneten Gebäudeteil angeordnet ist, also die gekrümmte Krafteinleitungsfläche des Kraftübertragungselements und das zugeordnete Gebäudeteil bzw. das dazwischen angeordnete Kraftverteilungsmittel zueinander beweglich angeordnet sind. Die Bewegung erfolgt in diesem Fall zweckmäßig um die Krümmungsachse, also insbesondere die Zylinderachse der gekrümmten Krafteinleitungsfläche des Kraftübertragungselements als Schwenkbzw. Wälzbewegung.Overall, it is advantageous if the carrier element allows a relative movement between the curved force application surface of the force transmission element and the associated part of the building or the force distribution means arranged between them, at least during installation, in order to enable corrections in the event of an imprecise installation position. It is particularly advantageous in this connection if these relative movements remain possible even after the installation of the carrier element, ie the error corrections can also be carried out later. For this it is important that the carrier element is movably arranged in the assigned part of the building, ie the curved force introduction surface of the force transmission element and the assigned part of the building or the force distribution means arranged between them are arranged movably with respect to one another. In this case, the movement is expediently about the axis of curvature, ie in particular the cylinder axis of the curved force application surface of the force transmission element as a swivel or rolling motion.

In Figur 1 ist eine erfindungsgemäße Verbindungsvorrichtung 1 angedeutet, die in einem zweiten getragenen Gebäudeteil 2 angeordnet ist und dazu dient, sich in ein erstes tragendes Gebäudeteil 3 zu erstrecken, welches in Figur 1 aus einer Gebäudewand besteht, die allerdings nur schematisch mit dem Bezugszeichen 3 angedeutet ist. Das Treppenteil gemäß Figur 1 besteht aus einem Treppenlauf einer Wendeltreppe, der aus Beton hergestellt ist und über verschiedene konstruktive Maßnahmen aufgelagert wird, so beispielsweise am oberen Ende des Treppenlaufs im Bereich 4. Eine dieser Maßnahmen besteht auch in der erfindungsgemäßen Verbindungsvorrichtung 1, die schematisch in Figur 2 dargestellt ist und aus einem Trägerelement 5 in Form eines Rechteckhohlprofilkörpers besteht, welches Trägerelement 5 sich - ggf. unter Zwischenfügung einer in Figur 2 nicht dargestellten Laufhülse - zwischen dem getragenen Gebäudeteil 2 und dem tragenden Gebäudeteil 3, so im vorliegenden Beispiel der Gebäudewand erstreckt. In Figur 2 ist der Teilbereich des Trägerelements 5, der sich im getragenen Gebäudeteil 2 erstreckt, mit gestrichelter Linienführung dargestellt, und der demgegenüber vorstehende und dem tragenden Gebäudeteil 3 zugeordnete Teilbereich mit durchgezogenen Linien dargestellt.In figure 1 a connection device 1 according to the invention is indicated, which is arranged in a second supporting building part 2 and serves to extend into a first supporting building part 3, which in figure 1 consists of a building wall, which, however, is only indicated schematically with the reference number 3 . The stair part according to figure 1 consists of a flight of stairs of a spiral staircase, which is made of concrete and is supported by various structural measures, for example at the upper end of the flight of stairs in area 4. One of these measures also consists of the connecting device 1 according to the invention, which is shown schematically in figure 2 is shown and consists of a carrier element 5 in the form of a rectangular hollow profile body, which carrier element 5 - possibly with the interposition of an in figure 2 barrel sleeve, not shown - extends between the supported part of the building 2 and the supporting part of the building 3, so in the present example of the building wall. In figure 2 the portion of the support element 5 that extends in the supported building part 2 is shown with dashed lines, and the portion that protrudes in comparison and is associated with the supporting building part 3 is shown with solid lines.

Dieser vorstehende und dem tragenden Gebäudeteil 3 zugeordnete Teilbereich des Trägerelements 5 erstreckt sich in einem trogförmigen Aussparungskörper 7, der in Figur 1 aufgrund der dort fehlenden Gebäudewand 3 vor dem Treppenteil 2 sichtbar dargestellt ist und insbesondere aus den Figuren 3, 4, 5 und 6 ersichtlich ist.This protruding part of the support element 5, which is assigned to the load-bearing part of the building 3, extends in a trough-shaped recess body 7, which is figure 1 is shown visible due to the missing building wall 3 in front of the stair part 2 and in particular from the Figures 3 , 4 , 5 and 6 is evident.

Der trogförmige Aussparungskörper 7 ist in die tragende Gebäudewand 3 eingebaut mit möglichst horizontaler Orientierung, um die Kräfte möglichst gleichmäßig aufzunehmen bzw. zu übertragen. Ist nun zwischen dem Trägerelement 5 und dem Aussparungskörper 7 eine Neigung bzw. Verdrehung um die Längsachse des Trägerelements 5 feststellbar, vor allem weil das Trägerelement 5 im getragenen Gebäudeteil 2 gegebenenfalls geneigt oder verdreht angeordnet ist, wie sich dies beispielsweise aufgrund des geneigten Treppenlaufs quasi von selbst ergibt, so hat jedoch diese verdrehte bzw. geneigte Orientierung des Trägerelements 5 gegenüber dem Aussparungskörper 7 keine Auswirkungen, wie nachfolgend näher beschrieben wird:
Wie in Figur 2 schematisch angedeutet ist und vor allem im Detail aus den Figuren 3 - 6 ersichtlich ist, weist der trogförmige Aussparungskörper 7 eine dünne Lastverteilerplatte 8 auf, die als Kraftverteilungsmittel fungiert und mit einem unter ihr angeordneten Schwingungsentkopplungselement 9 in Form eines Elastomerlagers zusammenwirkt. Um das Elastomerlager möglichst gleichmäßig zu belasten, ist es wichtig, dass die Lastverteilerplatte 8 möglichst horizontal orientiert bzw. eingebaut ist und mittig belastet wird, so dass dann bei einer entsprechenden auf die Lastverteilerplatte wirkenden Kraft die Kraft gleichmäßig über die gesamte Krafteinleitungsfläche übertragen werden kann.The trough-shaped recess body 7 is built into the supporting building wall 3 with the most horizontal orientation possible in order to absorb and transmit the forces as evenly as possible. Is now between the support member 5 and the recess body 7 an inclination or rotation about the longitudinal axis of the support member 5 can be determined, mainly because the support member 5 in the supported part of the building 2 is possibly inclined or twisted, as is the case, for example, due to the inclined flight of stairs, this twisted or inclined orientation of the support element 5 in relation to the recess body 7 has no effect, as will be described in more detail below:
As in figure 2 is indicated schematically and especially in detail from the Figures 3 - 6 As can be seen, the trough-shaped recess body 7 has a thin load distribution plate 8 which acts as a force distribution means and interacts with a vibration decoupling element 9 arranged below it in the form of an elastomer bearing. In order to load the elastomer bearing as evenly as possible, it is important that the load distribution plate 8 is oriented or installed as horizontally as possible and that it is loaded centrally, so that the force can then be transmitted evenly over the entire force application area when there is a corresponding force acting on the load distribution plate.

In Figur 3 ist die Verbindungsvorrichtung aus Figur 2 ohne das getragene Gebäudeteil, dafür aber mit dem Aussparungskörper 7 und der darin angeordneten Lastverteilerplatte 8 sowie dem darunter positionierten Schwingungsentkopplungselement 9 dargestellt und zeigt somit gut erkennbar den Rechteckhohlprofilkörper des Trägerelements 5, der entsprechend der Rechteckform vier Profilstege 5a, 5b, 5c, 5d aufweist, von denen die Profilstege 5a und 5c parallel zueinander angeordnet sind und die Profilstege 5b und 5d rechtwinklig hierzu, jedoch ebenso parallel zueinander. Alle vier Profilstege erstrecken sich in Längsrichtung x des Trägerelements 5 vom ersten tragenden Gebäudeteils 3 zum zweiten getragenen Gebäudeteil 2.In figure 3 the connection device is off figure 2 without the supported building part, but with the recess body 7 and the load distribution plate 8 arranged therein as well as the vibration decoupling element 9 positioned underneath and thus clearly shows the rectangular hollow profile body of the carrier element 5, which has four profile webs 5a, 5b, 5c, 5d corresponding to the rectangular shape, of which the profile webs 5a and 5c are arranged parallel to one another and the profile webs 5b and 5d at right angles thereto, but also parallel to one another. All four profile webs extend in the longitudinal direction x of the support element 5 from the first load-bearing part of the building 3 to the second load-bearing part of the building 2.

Figur 4 zeigt in der Vorderansicht ebenfalls deutlich die Rechteckform des Profilkörpers 5, die Lastverteilerplatte 8, das Schwingungsentkopplungselement 9 und den das Trägerelement 5, die Lastverteilerplatte 8 und das Schwingungsentkopplungselement 9 umgebenden trogförmigen Aussparungskörper 7. Zwischen Lastverteilerplatte 8 und Schwingungsentkopplungselement 9 ist in Figur 4 ein Zwischenraum dargestellt, der jedoch nur aus einem nicht zwischen Lastverteilerplatte 8 und Schwingungsentkopplungselement 9, sondern in der Vorderansicht in Figur 4 vor diesen verlaufenden Verbindungssteg 7b des Aussparungskörpers 7 besteht. In Figur 4 sind zwei Schnittverläufe A-A (Vertikalschnitt) und B-B (Horizontalschnitt) eingezeichnet, die in den Figuren 5 und 6 dargestellt sind. figure 4 also clearly shows the rectangular shape of the profile body 5, the load distribution plate 8, the vibration decoupling element 9 and the trough-shaped recess body 7 surrounding the carrier element 5, the load distribution plate 8 and the vibration decoupling element 9 in a front view. Between the load distribution plate 8 and the vibration decoupling element 9 is figure 4 an intermediate space is shown, which, however, only consists of a not between load distribution plate 8 and vibration decoupling element 9, but in the front view in figure 4 in front of this running connecting web 7b of the recess body 7 consists. In figure 4 are two cuts AA (vertical cut) and BB (horizontal section) drawn in the Figures 5 and 6 are shown.

Figur 5 zeigt anschaulich die Längserstreckung des Trägerelements 5 mit einer Längsrichtung x und einem ersten Längsabschnitt x1, der dem ersten Gebäudeteil 3 zuordnet ist und einen zweiten Längsabschnitt x2, der dem zweiten Gebäudeteil 2 zugeordnet ist. In diesen Längsabschnitten x1, x2 befinden sich Krafteinleitungsbereiche 11 (bei x1) und 12 (bei x2). figure 5 shows clearly the longitudinal extension of the carrier element 5 with a longitudinal direction x and a first longitudinal section x 1 , which is assigned to the first building part 3 and a second longitudinal section x 2 , which is assigned to the second building part 2 . Force application areas 11 (at x 1 ) and 12 (at x 2 ) are located in these longitudinal sections x 1 , x 2 .

Bei der in der Zeichnung dargestellten Ausführungsform ist im Krafteinleitungsbereich 11 ein Kraftübertragungselement 13 angeordnet und zwar auf der Unterseite des Trägerelements 5 benachbart zum unteren Profilsteg 5a. Das Kraftübertragungselement 13 ist - wie man vor allem aus Figur 4 erkennen kannaus einem Segment eines Zylinders gebildet mit einer kreisbogenförmigen Oberflächenkrümmung auf seiner Unterseite, die eine Krafteinleitungsfläche 13a bildet und einer ungekrümmten ebenen oberen Oberfläche 13b mit der das Kraftübertragungselement 13 am Profilsteg 5a des Trägerelements 5 anliegt und dort mit diesem verschweißt ist. Das Kraftübertragungselement beaufschlagt mit seiner Krafteinleitungsfläche 13a die Lastverteilerplatte 8 in einem sehr schmalen, fast linienförmigen Bereich, dem Anlagebereich zwischen der kreisbogenförmigen Krümmung 13a und der ebenen ungekrümmten Oberfläche der Lastverteilerplatte 8 (siehe Figur 4), von der die Kraft auf das darunterliegende Schwingungsentkopplungselement 9 übertragen wird.In the embodiment shown in the drawing, a force transmission element 13 is arranged in the force introduction area 11, namely on the underside of the carrier element 5 adjacent to the lower profile web 5a. The power transmission element 13 is - as you mainly from figure 4 can be seen from a segment of a cylinder formed with a circular arc-shaped surface curvature on its underside, which forms a force application surface 13a and an uncurved, flat upper surface 13b with which the force transmission element 13 rests on the profile web 5a of the carrier element 5 and is welded to it there. With its force introduction surface 13a, the force transmission element acts on the load distribution plate 8 in a very narrow, almost linear area, the contact area between the arcuate curvature 13a and the flat, uncurved surface of the load distribution plate 8 (see Fig figure 4 ), from which the force is transmitted to the underlying vibration decoupling element 9.

Figur 4 kann man ebenfalls entnehmen, dass der trogförmige Aussparungskörper 7 eine Öffnung 17 aufweist, die das Trägerelement 5 aufnimmt und hierzu eine nahezu kreiszylindrische hülsenähnliche Form aufweist, die an die Dimensionen des Trägerelements 5 angepasst ist und hierbei auch ein Verdrehen des Trägerelements 5 um seine Längsachse X nicht behindert. figure 4 can also be seen that the trough-shaped recess body 7 has an opening 17, which accommodates the carrier element 5 and for this purpose has an almost circular-cylindrical sleeve-like shape, which is adapted to the dimensions of the carrier element 5 and here also a rotation of the carrier element 5 about its longitudinal axis X not disabled.

Beim Verdrehen des Trägerelements 5 um seine Längsachse X werden jeweils andere Oberflächenbereiche der Krafteinleitungsfläche 13a des Kraftübertragungselements 13 in Anlage an die Lastverteilerplatte 8 gebracht und sorgen für eine Kraftübertragung, ohne dass sich die Größe der Übertragungsfläche bzw. der Kontaktfläche zwischen Krafteinleitungsfläche 13a und Lastverteilerplatte 8 ändern.When the carrier element 5 is rotated about its longitudinal axis X, other surface areas of the force introduction surface 13a of the force transmission element 13 are brought into contact with the load distribution plate 8 and ensure force transmission without the size of the transmission surface or the contact surface between the force introduction surface 13a and the load distribution plate 8 changing .

In Figur 7 ist nun schematisch das Trägerelement 5 aus den Figuren 2 bis 6 dargestellt mit angeschweißtem Kraftübertragungselement 13, darunter angeordneter scheibenförmiger Lastverteilerplatte 8 und wiederum unter der Lastverteilerplatte 8 angeordnetem quaderförmigen Schwingungsentkopplungselement 9.In figure 7 is now schematically the carrier element 5 from the Figures 2 to 6 shown with a welded-on power transmission element 13, a disk-shaped load distribution plate 8 arranged underneath it, and a cuboid vibration decoupling element 9 arranged underneath the load distribution plate 8.

Während Figur 8b das Trägerelement mit angeschweißtem Kraftübertragungselement 13 in der nicht verdrehten Neutralstellung zeigt, bei der die durch die Mittelachse X des Trägerelements 5 gehende Ebene 5e, die sich parallel zu den Profilstegen 5a, 5c, die breiter als die anderen beiden Profilstege 5b und 5d angeordnet sind, erstreckt, parallel zur Oberseite 8a der Lastverteilerplatte 8 angeordnet ist, ist im Gegensatz dazu in Figur 8b eine um einen Winkel α verdrehte Position des Trägerelements 5 gezeigt, bei der die besagte Ebene 5e, die sich parallel zu den Profilstegen 5a, 5c erstreckt, in einem Winkel α gegenüber der Oberseite 8a der Lastverteilerplatte 8 angeordnet ist. Dieser Winkel α entspricht der maximalen Schrägstellung des Trägerelements, da die Verdrehung um die Längsachse X von der Kante zwischen den Profilstegen 5a und 5b begrenzt wird, die in Kontakt mit der Oberfläche 8a der Lastverteilerplatte 8 bei dieser maximalen Schrägstellung gelangt.During Figure 8b shows the carrier element with the welded-on force transmission element 13 in the non-twisted neutral position, in which the plane 5e passing through the central axis X of the carrier element 5, which extends parallel to the profile webs 5a, 5c, which are arranged wider than the other two profile webs 5b and 5d, extends, is arranged parallel to the upper side 8a of the load distribution plate 8, in contrast to this Figure 8b a position of the carrier element 5 rotated by an angle α is shown, in which said plane 5e, which extends parallel to the profile webs 5a, 5c, is arranged at an angle α with respect to the upper side 8a of the load distribution plate 8. This angle α corresponds to the maximum inclination of the carrier element since the torsion about the longitudinal axis X is limited by the edge between the profile webs 5a and 5b coming into contact with the surface 8a of the load distribution plate 8 at this maximum inclination.

Figur 9b entspricht der Ausführungsform aus Figur 8b mit dem einzigen Unterschied, dass nunmehr bei einem dort dargestellten Trägerelement 25 statt des Kraftübertragungselements 13 ein alternatives Kraftübertragungselement 23 verwendet wurde, welches einen größeren Krümmungsradius aufweist als das Kraftübertragungselement 13 aus den Figuren 2 bis 8. Dieser größere Radius hat zur Folge, dass die besagte Kante zwischen den Profilstegen 5a und 5b nicht mehr die Drehbewegung des Trägerelements 25 behindert, sondern von dem Kraftübertragungselement 23 überdeckt wird, woraus ein größerer maximaler Drehwinkel α resultiert. Figure 9b corresponds to the embodiment Figure 8b with the only difference that now in a carrier element 25 shown there instead of the force transmission element 13 an alternative force transmission element 23 was used, which has a larger radius of curvature than the force transmission element 13 from the Figures 2 to 8 . The consequence of this larger radius is that said edge between the profile webs 5a and 5b no longer impedes the rotational movement of the carrier element 25, but is covered by the force transmission element 23, resulting in a larger maximum angle of rotation α.

Die Figuren 10a und 10b zeigen die Ausführungsform aus Figur 9a und 9b mit dem Unterschied, dass bei einem dort dargestellten Trägerelement 35 an den schmalen Profilstegen 5b, 5d ebenfalls Teile 33c, 33d eines Kraftübertragungselements 33 vorgesehen sind, die somit auch die besagten schmalen Profilstege überdecken und somit den möglichen Drehwinkel α weiter vergrößern.the Figures 10a and 10b show the embodiment Figure 9a and 9b with the difference that in a carrier element 35 shown there, parts 33c, 33d of a force transmission element 33 are also provided on the narrow profile webs 5b, 5d, which thus also cover said narrow profile webs and thus further increase the possible angle of rotation α.

Und schließlich ist in Figuren 11a, 11b eine Ausführungsform eines Trägerelements 45 dargestellt, bei der auch noch der auf der dem Profilsteg 5a gegenüberliegenden Seite angeordnete Profilsteg 5c mit einem Teil 43e des Kraftübertragungselements 43 überdeckt wird, wobei nunmehr alle Profilstege von entsprechenden Teilen 43, 43c, 43d, 43e des Kraftübertragungselements 43 überdeckt sind, welches wiederum insgesamt die Form eines um das Trägerelement 45 umlaufenden Zylinders aufweist. Der maximale Drehwinkel α ist hierbei unbegrenzt, also einem Runddorn vergleichbar.And finally is in Figures 11a, 11b An embodiment of a carrier element 45 is shown, in which the profile web 5c arranged on the side opposite the profile web 5a is also covered with a part 43e of the force transmission element 43, with all profile webs now being covered by corresponding parts 43, 43c, 43d, 43e of the force transmission element 43 are, which in turn has the overall shape of a cylinder rotating around the carrier element 45 . The maximum angle of rotation α is unlimited, i.e. comparable to a round mandrel.

Zusammenfassend bietet die vorliegende Erfindung den Vorteil, eine im Vergleich zu aus Vollmaterial bestehenden Dornverbindungen im Hinblick auf Biegemomente höher belastbare Verbindungsvorrichtung zur Verfügung zu stellen, die gleichzeitig aber auch Einbaufehler dadurch verzeiht, dass die Verdrehung des entsprechenden Trägerelements in Bezug auf seine Längsachse keine Änderungen der Größe der in die Kraftübertragung einbezogenen Oberfläche verursacht, die Kontakt mit einer Lastverteilerplatte oder einem entsprechenden anderen Bauteil aufweist. Beim Einbau in geneigte Bauteile wie z.B. Treppen besteht ein weiterer Vorteil in der geringen Einbauhöhe, da das Trägerelement in seiner Neigung der Treppenlaufneigung angepasst werden kann.In summary, the present invention offers the advantage of providing a connecting device that can withstand higher loads in terms of bending moments compared to mandrel connections made of solid material, but which at the same time forgives installation errors in that the twisting of the corresponding support element in relation to its longitudinal axis does not change the The amount of surface area involved in the powertrain that is in contact with a load distribution plate or other equivalent component. When installing in inclined components such as stairs, there is another advantage in the low installation height, since the inclination of the support element can be adapted to the inclination of the staircase.
