Abstract

The beam accommodates compression or shear forces in a building structure. The building structure is interrupted by a gap or is connected to another building structure, e.g. in balcony structures separated from internal structures by thermal insulation. Preferably a cantilevered panel (1) is connected to a structure (2), e.g. of reinforced concrete, by a compression plate (4) having supporting face components normal to shear and compression forces. The plate is inclined to the shear force direction. It can be angled, having a steep lower portion and a flat upper portion, and may be toothed and or have a rough, profiled surface.

Description

Die Erfindung betrifft eine Vorrichtung zur gemeinsamen Aufnahme von Druck- und Querkräften für den Fall, daß eine Konstruktion entweder durch eine Fuge unterbrochen wird, über die die Schnittgrößen übertragen werden müssen oder daß sie an eine Konstruktion aus anderen Baustoffen kraftübertragend angeschlossen werden muß oder bei sonstigen vergleichbaren Gegebenheiten.The invention relates to a device for joint recording of printing and Transverse forces in the event that a construction interrupted either by a joint is, over which the internal forces must be transmitted or that they connected to a construction of other building materials force transmitting must or in other similar circumstances.

Diese Ausgangssituation tritt beispielhaft im Bauwesen häufig auf im Zusammenhang mit Balkon- und Loggiakonstruktionen, die von den innerhalb der Fassadenhülle angeordneten Bauteilen durch Dämmfugen thermisch getrennt werden. Es kann sich hierbei um frei auskragende oder aber auch um an der Außenseite schräg abgehängte Konstruktionen aus Stahlbeton, Holz, Stahl oder anderen geeigneten Werkstoffen handeln. Die kraftschlüssige Verbindung über die Fuge kann zum jeweils gleichen Baustoff oder auch zu einem der anderen genannten hergestellt werden. Für den Fall frei auskragender Stahlbetonplatten stehen bereits verschiedene Lösungen zur Verfügung, die aber überwiegend dadurch gekennzeichnet sind, daß für die Aufnahme der Biegedruckkräfte sowie der Querkräfte jeweils getrennte Bauelemente angeordnet werden.This initial situation occurs frequently in the construction industry, for example with balcony and loggia construction by the inside of the facade arranged components are thermally separated by Dämmfugen. It This can be freely cantilevered or inclined at the outside Suspended constructions of reinforced concrete, wood, steel or other suitable Act materials. The non-positive connection via the joint can be to each same building material or else to one of the other mentioned. In the case of cantilevered reinforced concrete slabs are already different Solutions available, but predominantly characterized are that for the recording of the bending compressive forces and the transverse forces each separate Components are arranged.

Zu den angesprochenen Lösungen gehören u. a. Bauelemente gemäß den Dokumenten DE 37 22 584 A 1, DE 90 01 016 U, DE 34 03 240 A 1 und DE 93 18 354 U. Das Dokument DE 37 22 584 A 1 stellt verschiedene Lösungen vor, bei denen zur Übertragung der Querkräfte Elemente so schräg angeordnet sind, dass sie von den Querkräften mit Druck beansprucht werden. Für die bei diesen Anwendungsfällen stets zusätzlich auftretenden Biegedruck- und -zugkräfte müssen aber zu deren Aufnahme und Weiterleitung zusätzliche Elemente eingebaut werden. Diese Vorrichtung ist somit nicht geeignet, Querkräfte und Biegedruckkräfte gemeinsam aufzunehmen. Among the solutions mentioned include u. a. Components according to the documents DE 37 22 584 A 1, DE 90 01 016 U, DE 34 03 240 A 1 and DE 93 18 354 U. Document DE 37 22 584 A 1 presents various solutions which elements are arranged so obliquely for transmitting the transverse forces, that they are subjected to pressure from the shear forces. For those with these applications always additionally occurring bending pressure and tensile forces but have to whose recording and forwarding additional elements are incorporated. These Device is thus not suitable, transverse forces and bending forces together take.

Im Gegensatz hierzu stellt das Dokument DE 90 01 016 U eine Lösung vor, bei der im unteren Teil des auskragenden Bauteils sowohl die Querkraft als auch die Biegedruckkraft aufgenommen wird - allerdings unabhängig voneinander von zwei getrennten Bauteilen: Die Biegedruckkkraft wird von einer Stirnplatte aufgenommen und mit einem Druckstab über die Fuge geleitet. Die Querkraft wird dagegen vollständig getrennt hiervon von einem girlandenförmigen Element im Bereich der unteren Krümmung neben der Stirnplatte aufgenommen.In contrast, the document DE 90 01 016 U proposes a solution at in the lower part of the cantilever component both the lateral force and the Bending force is absorbed - but independently of two Separate components: The bending compressive force is absorbed by a front plate and passed over the joint with a push rod. The shear force, on the other hand, becomes complete separated from this by a garland-shaped element in the region of the lower Curvature taken next to the face plate.

Hiervon abweichend bietet das Dokument DE 34 03 240 A 1 tatsächlich ein Element an, das sowohl Quer- als auch Biegedruckkräfte aufnehmen kann. Bei dieser Lösung sollen zwar beide genannten Kraftkomponenten allein mit Hilfe eines in Druckkraftrichtung angeordneten, biegesteifen Elements über die Fuge geleitet werden. Die Querkraft erzeugt dabei in diesem Element jedoch ein sekundäres Biegemoment, das allerdings auf der lastaufnehmenden Seite kein Gleichgewicht findet. Dieses Beispiel ist daher für die praktische Anwendung nicht geeignet.Deviating from this, the document DE 34 03 240 A1 actually offers an element on, which can absorb both transverse and bending forces. At this Although both components of force should be determined solely with the help of an in. Solution Compressed force direction arranged, rigid element to be passed over the joint. However, the transverse force generates a secondary bending moment in this element, which, however, finds no balance on the load-bearing side. This example is therefore not suitable for practical use.

Das gleiche Prinzip liegt auch einer Lösung des Dokuments DE 93 18 354 U zu Grunde. Das auch hier entstehende Versatzmoment findet nur in denjenigen Anwendungsfällen ein Gleichgewicht, bei denen unter der lastaufnehmenden Deckenplatte neben der Dämmfuge noch ein Auflager in Form einer Wand oder eines Unterzugs vorhanden ist. Da aber regelmäßig unter auskragenden Platten Fensteröffnungen bis direkt unter die Platte reichen, ist diese Voraussetzung meist nicht erfüllt.The same principle also applies to a solution of the document DE 93 18 354 U. Reasons. The offset torque also occurs only in those applications a balance in which under the load-bearing ceiling panel in addition to the Dämmfuge still a support in the form of a wall or a beam is available. But there regularly under projecting panels window openings reach right up to the plate, this condition is usually not met.

Hiervon ausgehend besteht die Aufgabe der vorliegenden Erfindung darin, die beiden genannten Kraftkomponenten Biegedruck und Querkraft mit einem einzigen Element aufzunehmen, um sie dann mit getrennten Elementen über die Fuge zu leiten.On this basis, the object of the present invention in it, the two mentioned Force components Bending pressure and shear force with a single element to then guide them with separate elements over the joint.

Die gestellte Aufgabe wird erfindungsgemäß durch das Kennzeichen des Anspruchs 1 gelöst. Es wird eine Druckplatte aus Stahl oder sonstigen geeigneten Werkstoffen vorgesehen, die nach Grösse, Lage, Ausrichtung (i. d. R. geneigt), Querschnittsgestaltung und / oder Oberflächenbeschaffenheit so ausgelegt, daß beide Schnittkraftkomponenten von einem einzigen Element aufgenommen werden können. The stated object is achieved by the characterizing part of the claim 1 solved. It will be a pressure plate made of steel or other suitable materials provided according to size, position, orientation (usually inclined), cross-sectional design and / or surface finish designed so that both cutting force components can be absorbed by a single element.

Dabei werden jedoch nur die aufgenommenen Biegedruckkraftkomponenten mit Hilfe eines Druckelements über die Fuge geleitet. Zur Übertragung der Querkraft schliessen umittelbar an den lastaufnehmenden Elementen Diagonalen an, die auf Zug beansprucht werden. Durch diese Anordnung werden schwierig aufzunehmende Versatzmomente vermieden. Dadurch werden die bei den bisher bekannten Lösungen auftretenden Nachteile vermieden und die folgenden Vorteile erreicht.However, only the recorded bending pressure force components with the help a pressure element passed over the joint. Close to transfer the shear force directly on the load-bearing elements diagonals on train be claimed. By this arrangement are difficult to be absorbed Offset moments avoided. This will be in the previously known solutions avoided disadvantages and achieves the following advantages.

Gegenüber den bislang bekannten Konstruktionen ergeben sich deutlich wirtschaftlicheren Lösungen, da weniger und kürzere Bauteile erforderlich werden. Weiterhin ist es insbesondere bei Stahl- und Spannbetonkonstruktionen günstig, Querkräfte gemeinsam mit der im Querschnitt unten wirkenden Druckkraft aufzunehmen, weil dann die Querkraft den Beton gleichfalls auf Druck beansprucht. Beton kann bekanntlich Druckkräfte sehr gut, Zugkräfte dagegen nur sehr begrenzt ohne Bewehrung aufnehmen. Weiterhin werden die Tragelemente, die die Querkraft über die Fuge leiten, günstig auf Zug beansprucht.Compared to the previously known constructions arise significantly more economical solutions, as fewer and shorter components required become. Furthermore, it is particularly in steel and prestressed concrete structures favorable, transverse forces together with the downward compressive force acting in cross-section because then the lateral force also stresses the concrete to pressure. Concrete is known to have compressive forces very well, but tensile forces are very limited without reinforcement. Furthermore, the supporting elements, which are the lateral force lead over the joint, favorably loaded on train.

Ein ganz wesentlicher Vorteil dieser Vorrichtung ergibt sich vor allem auch aus der extrem kurzen Längenentwicklung, die durch die gemeinsame Aufnahme von Druckund Querkräften erreicht werden kann: Im unten liegenden Druckbereich kann die vorliegende Vorrichtung mit so geringen Überständen über die Fuge ausgebildet werden, dass sie noch leicht eingebaut werden kann, nachdem die übrige Bewehrung der anschließenden Stahlbetonbauteile bereits verlegt wurde. Dies vereinfacht den Arbeitsablauf auf der Baustelle ganz erheblich.A very important advantage of this device is especially evident from the extremely short length development, due to the joint absorption of pressure and Transverse forces can be achieved: In the lower pressure range, the present device with such small projections formed over the joint be that it can still be easily installed after the remaining reinforcement the subsequent reinforced concrete components has already been laid. This is simplified the work process on the construction site quite considerably.

Die Darstellung der aufgeführten Beispiele orientiert sich an Anwendungsbeispielen frei auskragender Balkonkonstruktionen, deren Schnittgrößen über Dämmfugen zu leiten sind. Die Erfindung kann sinngemäß eingesetzt werden, wenn auf der Zeichnung jeweils rechts eine Holz- oder Stahlkonstruktion anschließt. Sie kann weiterhin angewendet werden für den Anschluß einer Konstruktion aus Holz oder sonstigen Werkstoffen an eine Betonkonstruktion oder auch zur Kraftübertragung zwischen Stahl- und Holzbauteilen.The representation of the examples listed is based on application examples freely cantilevered balcony constructions, their internal dimensions over Dämmfugen too are guiding. The invention can be used analogously, if in the drawing each right joins a wooden or steel construction. She can continue be used for connecting a construction made of wood or other Materials to a concrete structure or for power transmission between Steel and wood components.

Die Figur 1 zeigt als Beispiel den Anschluß einer auskragenden Stahlbeton-Balkonplatte 1 an eine innerhalb der Dämmfuge fortgeführte Stahlbetonkonstruktion 2. Für das Gleichgewicht der Kragplatte ist es erforderlich, daß sowohl Biegedruckund -zugkräfte als auch Querkräfte über die Dämmfuge geleitet werden. Die Biegezugkräfte werden am oberen Plattenrand mit der günstig zu stoßenden Konstruktion 3 über die Dämmfuge geleitet. Mit der erfindungsgemäßen Vorrichtung 4 in Form einer schrägen Druckplatte werden gleichzeitig die horizontal wirkenden Biegedruckkräfte und die vertikal wirkenden Querkräfte aufgenommen. Die horizontalen Kraftkomponenten werden mit einem drucksteifen Element 5 über die Dämmfuge hin zu einer entgegengesetzt geneigten Druckplatte geleitet. Die beiden Druckplatten sind dachförmig gegeneinander geneigt. Die vertikalen Kraftkomponenten werden von zwei an der ersten Druckplatte angreifenden Diagonalen 6 aufgenommen und auf der anderen Seite der Dämmfuge, hier rechts, oben in den Beton geleitet.Figure 1 shows an example of the connection of a projecting reinforced concrete balcony slab 1 to a reinforced concrete structure 2 continued within the insulation joint. For the balance of the cantilever plate, it is necessary that both bending pressure and Pulling forces and shear forces are passed through the Dämmfuge. The bending tensile forces be at the upper edge of the plate with the cheap to bump construction 3 passed over the Dämmfuge. With the device 4 according to the invention in the form an oblique pressure plate are at the same time the horizontally acting bending pressure forces and the vertical transverse forces absorbed. The horizontal Force components are with a pressure-resistant element 5 through the Dämmfuge directed to an oppositely inclined pressure plate. The two printing plates are roof-shaped inclined towards each other. The vertical force components become received by two engaging on the first pressure plate diagonal 6 and on the other side of the Dämmfuge, right here, headed up into the concrete.

Die Figuren 2 und 3 zeigen eine Ausgestaltung mit einer stark profilierten, hier gezahnten Druckplatte 7 auf der Krafteinleitungsseite. Bei der stark profilierten Druckplatte 7 nach den Figuren 2 und 3 können die Biegedruckkräfte von den vertikalen Flächenanteilen und die Querkräfte von den horizontalen Flächenanteilen aufgenommen werden. Für die Unterstützung der Druckplatte zur Übertragung der horizontalen Kraftkomponenten sind in diesem Beispiel paarweise angeordnete, horizontale Rundstäbe 8 dargestellt. Für die Aufnahme der Querkraft sind gleichfalls paarweise angeordnete, diagonale Rundstäbe 9 vorgesehen. Natürlich sind die lastübernehmenden Elemente beliebig untereinander und mit den verschiedenen Varianten der Druckplatten kombinierbar.Figures 2 and 3 show an embodiment with a strongly profiled, toothed here Pressure plate 7 on the force introduction side. In the strongly profiled Pressure plate 7 according to Figures 2 and 3, the bending pressure forces of the vertical Area shares and the transverse forces of the horizontal area shares be recorded. For supporting the printing plate for transferring the horizontal force components are arranged in pairs in this example, horizontal rods 8 shown. For absorbing the lateral force are also arranged in pairs, diagonal rods 9 provided. Of course they are the load-bearing elements with each other and with the various Variants of printing plates can be combined.

Der Lösungsansatz nach Figur 4 macht von der Tatsache Gebrauch, daß sich das Verhältnis der Kraftgrößen aus Biegedruck bzw. Querkraft für die praktisch interessanten Anwendungsfälle in bestimmten Grenzen bewegt. Entsprechend gibt es für die Richtung der Resultierenden aus beiden Kräften Grenzwerte, die nicht überschritten werden. Demzufolge reicht eine einfache, eventuell angerauhte oder leicht profilierte Druckplatte 10 aus, die nach der mittleren Richtung der zu erwartenden Kraftresultierenden ausgerichtet wird; davon abweichende Komponenten werden als Reibungskräfte aufgenommen. Als Unterstützung ist nun ein einzelner Druckstab 11 in Kombination mit paarweise angeordneten Rundstäben 12 für die Diagonalen dargestellt.The approach of Figure 4 makes use of the fact that the Ratio of the force values of bending pressure and lateral force for the practically interesting Use cases within certain limits. Accordingly, there is for the direction of the resultant of both forces limit values that did not exceed become. Consequently, a simple, possibly roughened or sufficient slightly profiled pressure plate 10, which is expected after the middle direction of the Force Resulting is aligned; other components are recorded as frictional forces. As support is now an individual Push rod 11 in combination with pairs of round rods 12 for the Diagonals shown.

Die Figur 5 zeigt als weiteres Anwendungsbeispiel den Anschluß frei auskragender Stahlträger 13 mit Hilfe der erfindungsgemäßen Vorrichtung an eine innerhalb der Dämmfuge 14 anschließende Stahlbetonkonstruktion 15. Die Biegezugkräfte werden im oberen Bereich der Stahlträger über eine Schraubverbindung 16 in die Zugstäbe 17 geleitet, die mit einer geeigneten Konstruktion 18 im Beton verankert werden. Mit der eine erfindungsgemäße Vorrichtung bildenden Platte 19 werden gleichzeitig die im unteren Stahlflansch 20 horizontal wirkenden Biegedruckkräfte und die im Steg 21 vertikal wirkenden Querkräfte aufgenommen. Hierzu erhält der Stahlträger zweckmäßigerweise eine Anschlußplatte 22, die parallel zur Platte 19 ausgerichtet ist. Als Montagehilfe und zur Übertragung kleinerer Differenzkräfte kann auf der Platte 19 ein die Anschlußplatte 22 durchgreifender Schraubdom 23 angeordnet werden. Die horizontalen Kraftkomponenten werden mit einem horizontalen, drucksteifen Element 24 über die Dämmfuge geleitet. Die vertikalen Kraftkomponenten werden von den Diagonalen 25 aufgenommen und rechts der Dämmfuge oben in den Beton geleitet. Hierzu können sie - wie dargestellt - mit den vorhandenen Zugstäben verschweißt werden. Alternativ können sie aber auch eine Verlängerung durch angeschweißte, gerippte Betonstahlstäbe erhalten und die entstehenden Zugkraftkomponenten über Verbund direkt in den Beton leiten.FIG. 5 shows, as a further example of application, the connection of freely projecting elements Steel beam 13 by means of the device according to the invention to a within the Dämmfuge 14 subsequent reinforced concrete structure 15. The bending tensile forces become in the upper part of the steel beam via a screw 16 in the tie rods 17 anchored with a suitable construction 18 in the concrete. With a device 19 according to the invention forming plate 19 are simultaneously the bending force acting horizontally in the lower steel flange 20 and the recorded in the web 21 vertically acting shear forces. For this receives the steel beam suitably a connection plate 22, which is aligned parallel to the plate 19 is. As an assembly aid and for the transmission of smaller differential forces can the plate 19 a the connecting plate 22 by cross screw 23 is arranged become. The horizontal force components are combined with a horizontal, pressure-resistant element 24 passed over the Dämmfuge. The vertical force components are recorded by the diagonal 25 and right of the Dämmfuge top in passed the concrete. For this they can - as shown - with the existing Tie rods are welded. Alternatively, they can also be an extension obtained by welded, ribbed reinforcing steel bars and the resulting Direct traction components via composite directly into the concrete.
