Description

Verbindungsmittel zur Kopplung  Connecting means for coupling
von zwei Bauelementen  of two components
Die Erfindung bezieht sich auf ein Verbindungsmittel zur Kopplung von zwei Bauelementen, insbesondere Betonfertigteilen, mit einem Bolzen, und Bauelemente. The invention relates to a connecting means for coupling two components, in particular precast concrete parts, with a bolt, and components.
Im Betonfertigteilbau werden Bauelemente, wie Betonfertigteile und insbesondere Betonplatten, zur Erstellung von Tragkonstruktionen, Fassaden, Wänden und/oder Decken verwendet, die an ihren Stoßkanten Nuten aufweisen, die zur Verbindung der Betonfertigteile mit Beton verfüllt werden und zusätzlich zur Aufnahme von Zugkräften mit Dübeln, Schrauben, Metallschlaufen oder Bügeln bestückt werden. Alle diese Verbindungselemente werden bereits während der Produktion in die Betonfertigteile eingesetzt, wobei die beiden zu verbindenden Betonfertigteile mit diesen Verbindungselementen bestückt werden müssen. In precast concrete construction elements, such as precast concrete elements and concrete slabs are used to create supporting structures, facades, walls and / or ceilings, which have grooves at their abutting edges, which are filled to connect the precast concrete with concrete and in addition to absorbing tensile forces with dowels, Screws, metal loops or ironing can be fitted. All these fasteners are already used during production in the precast concrete parts, the two precast concrete parts to be joined must be equipped with these fasteners.
Zur Verbindung von zwei Bauelementen ist es z. B. aus der DE 10 2010 030 281 A1 bekannt, Bolzen zu verwenden, die beispielsweise mit einem Gewinde versehen sind und unmittelbar in das Bauelement oder in einen in dem Bauelement befestigten Dübel geschraubt werden. Bei der Verwendung eines solchen Bolzens ist es nicht möglich, zwei Bauelemente auf Stoß miteinander zu koppeln. Es bleibt stets ein Spalt, in dem ein Werkzeug an dem Bolzen zu dessen Verdrehung angreifen kann. For the connection of two components, it is z. B. from DE 10 2010 030 281 A1 known to use bolts that are provided for example with a thread and directly into the device or screwed into a dowel fastened in the component. When using such a bolt, it is not possible to couple two components together. It always remains a gap in which a tool can attack on the bolt to its rotation.
Der Erfindung liegt die Aufgabe zugrunde, ein Verbindungsmittel der eingangs genannten Art zu schaffen, das bei einer einfachen Handhabung eine Verbindung von zwei Bauelementen sicherstellt und verhältnismäßig große Kräfte überträgt. The invention has for its object to provide a connecting means of the type mentioned, which ensures a simple handling of a compound of two components and transmits relatively large forces.
Erfindungsgemäß wird die Aufgabe durch die Merkmale der unabhängigen Ansprüche gelöst. According to the invention the object is solved by the features of the independent claims.
Die Unteransprüche stellen vorteilhafte Ausgestaltungen der Erfindung dar. The subclaims represent advantageous embodiments of the invention.
Ein Verbindungsmittel zur Kopplung von zwei Bauelementen, insbesondere Betonfertigteilen, umfasst einen Bolzen, der mindestens ein axial festgelegtes Federelement trägt, das im montierten Zustand des Verbindungsmittels einer auf den Bolzen wirkenden Auszugskraft entgegenwirkt. A connecting means for coupling two components, in particular precast concrete parts, comprises a bolt which carries at least one axially fixed spring element, which counteracts an extracting force acting on the bolt in the assembled state of the connecting means.
Die Ausgestaltung des Verbindungsmittels kann relativ vielfältig sein, umfasst jedoch stets mindestens eine in axialer Richtung wirksames Federelement, das entweder auf den Bolzen aufgesetzt, also mit diesem kraft- und/oder formschlüssig verbunden, oder einstückig mit den Bolzen gefertigt ist. Der Bolzen kann nach Art eines mit einem federnden Widerhaken oder einer federnden Zunge versehenen Nagels mit einem Hammerschlag in eine vorgefertigte Bohrung eingesetzt werden, um beispielsweise ein Metallbauteil an einem Betonbauelement, insbesondere einem Betonfertigteil, zu befestigen. Hierzu weist der Bolzen beispielsweise an seinem einen Ende einen gegenüber dem übrigen Verlauf vergrößerten Kopf und an dem dem Kopf gegenüberliegenden Ende eine Phase oder eine Querschnittsverjüngung auf, die beispielsweise auch das Federelement trägt. Es kann aber auch ein zylindrischer Bolzen verwendet werden, bei dem das Federelement sich beispielsweise über den gesamten Umfang erstreckend oder als eine Art Widerhaken angeordnet oder ausgebildet ist. The design of the connecting means may be relatively diverse, but always includes at least one effective in the axial direction of the spring element, which is either placed on the bolt, that is positively and / or positively connected, or is made in one piece with the bolt. The bolt may be in the manner of a nail provided with a resilient barb or a resilient tongue a hammer blow are used in a prefabricated hole to attach, for example, a metal component to a concrete component, in particular a precast concrete part. For this purpose, the bolt has, for example, at one end a head which is larger than the rest of the course and at the end opposite the head a phase or a cross-sectional taper which, for example, also carries the spring element. But it can also be used a cylindrical bolt, wherein the spring element, for example, over the entire circumference extending or arranged or formed as a kind of barbs.
Selbstverständlich ist die Verwendung des erläuterten Verbindungsmittels nicht nur bei einem Bauelement aus Beton, sondern auch im Zusammenhang mit Bauelementen aus Holz, Kunststoff und dergleichen Werkstoffen möglich, ohne den Rahmen der Erfindung zu verlassen. Of course, the use of the illustrated connecting means not only in a concrete element, but also in connection with components made of wood, plastic and the like materials is possible without departing from the scope of the invention.
In Ausgestaltung trägt der Bolzen mindestens zwei gegenläufig wirksame Federelemente. Die beispielsweise als Federarme oder Federscheiben ausgebildeten Federelemente verklemmen in entsprechenden Öffnungen der miteinander zu verbindenden Bauelemente, wobei die Klemmwirkung bei einer wirkenden Auszugskraft zunimmt. Beim Einstecken in die Öffnung werden die Federelemente zur Verringerung ihrer lichten Weite zusammengedrückt, wobei die Richtung zum Fügen des Verbindungsmittels und der Bauelemente der Richtung der Auszugskraft entgegengesetzt ist. Wenn die Bolzen und die Federelemente aus einem entsprechend festen Material gefertigt sind, können verhältnismäßig große Kräfte übertragen werden, ohne dass die Kopplung der durch die Verbindungsmittel miteinander verbundenen Bauelemen- te aufgehoben wird oder die verwendeten Verbindungsmittel beschädigt werden. In an embodiment, the bolt carries at least two counteracting spring elements. The example formed as spring arms or spring washers spring elements jam in corresponding openings of the components to be joined together, wherein the clamping action increases at an acting pull-out force. When inserted into the opening, the spring elements are compressed to reduce their clearance, wherein the direction for joining the connecting means and the components of the direction of the pull-out force is opposite. If the bolts and the spring elements are made of a correspondingly strong material, relatively large forces can be transmitted without the coupling of the components connected to one another by the connecting means being transmitted. te is canceled or damage the fasteners used.
Vorzugsweise ist das Federelement als eine Federzahnscheibe ausgebildet, die in eine Bohrung des Bauelementes vorgespannt einsetzbar ist. Zweckmäßigerweise weist die Federzahnscheibe eine elliptische, ovale oder vielkantige Au ßenkontur auf. Tellerförmige Federzahnscheiben sind als genormte Produkte kostengünstig erhältlich und eine zylindrische Bohrung mit einem Durchmesser, der etwas kleiner als der Außendurchmesser der Zahnscheibe gefertigt ist, kann einfach hergestellt werden. Es ist aber auch denkbar, die Federzahnscheibe mit einer Außenkontur zu fertigen, die beispielsweise eine Erhöhung der Klemmwirkung, einen Einsatz in einer von einer zylindrischen Bohrung verschiedenen Öffnung oder eine Fertigung unter dem Gesichtspunkt eines reduzierten Ausschusses ermöglicht. Preferably, the spring element is designed as a spring toothed disc, which is used biased in a bore of the component. Appropriately, the spring toothed disc on an elliptical, oval or polygonal Au ßenkontur. Disc-shaped spring tooth discs are available as standardized products cost and a cylindrical bore with a diameter which is made slightly smaller than the outer diameter of the toothed disc can be easily manufactured. But it is also conceivable to produce the spring toothed disc with an outer contour, which allows, for example, an increase in the clamping action, an insert in a different opening of a cylindrical bore or a production from the viewpoint of a reduced Committee.
Um das Federelement unverschiebbar auf dem Bolzen festzulegen, weist nach einer Weiterbildung der Bolzen mindestens einen Absatz oder einen umlaufenden Einstich auf, der das Federelement axial fixiert. In order to fix the spring element immovably on the bolt, has according to a development of the bolt at least one shoulder or a circumferential groove, which fixes the spring element axially.
Zweckmäßigerweise weist das Federelement an seinem Innen- und/oder Außendurchmesser eine Verzahnung auf und ist insbesondere zylindrisch gestaltet. Die Verzahnung krallt sich an dem jeweiligen Bauelement fest, wobei aufgrund der relativ kleinen Anlagefläche der einzelnen Zähne bei einer entsprechend vorgespannten Montage hohe radiale Kräfte wirksam sind, die einer axialen Auszugskraft entgegenwirken. Mit dem zuvor erläuterten Verbindungsmittel ist die Verbindung von zwei aneinanderstoßenden Bauelementen möglich. Conveniently, the spring element on its inner and / or outer diameter has a toothing and is designed in particular cylindrical. The toothing clings to the respective component firmly, due to the relatively small contact surface of the individual teeth in a correspondingly biased assembly high radial forces are effective, which counteract an axial pull-out force. With the connection means described above, the connection of two abutting components is possible.
Beispielsweise sind eckige Bauelemente stumpf aneinander stoßend mittels mindestens eines Verbindungsmittels miteinander koppelbar, in dem das Verbindungsmittel mit einem ersten Abschnitt vorzugsweise in eine Bohrung des einen Bauelementes unter der Wirkung des oder der Federelemente des ersten Abschnitts eingesetzt wird und das andere Bauelement auf den vorstehenden zweiten Abschnitt des Verbindungsmittels aufgeschoben wird, bis insbesondere die beiden Bauelemente stumpf aneinanderstoßend miteinander verbunden sind und in Bohrungen der beiden Bauelemente Federelemente eines Verbindungselementes vorteilhafterweise gegen Auszugskräfte wirksam sind. For example, angular components can be butted together by means of at least one connecting means in which the connecting means is preferably used with a first portion in a bore of one component under the action of the spring or the first portion and the other component on the above second section the connecting means is pushed until, in particular, the two components are butt-abutting connected to each other and in bores of the two components spring elements of a connecting element are advantageously effective against pull-out forces.
Bei den Bauelementen kann es sich um jegliche Art von Betonbauteilen, insbesondere sogenannten Betonfertigteilen, wie Stützen, Träger, Binder, Fassaden, Treppen, Stürze, Decken- oder Wandplatten oder Pfosten handeln. Auch eine Kombination dieser Bauelemente mit anderen Bauelementen, beispielsweise aus Stahl, in Form von Winkel-, T- oder Doppel-T-Profilen ist möglich. The components may be any type of concrete components, in particular so-called precast concrete parts, such as columns, beams, trusses, facades, stairs, lintels, ceiling or wall panels or posts. A combination of these components with other components, such as steel, in the form of angle, T or double T-profiles is possible.
In Ausgestaltung ist mindestens eine Stirnseite mit Bohrungen zur vorgespannten Aufnahme der mindestens einen Federzahnscheibe des Verbindungsmittels versehen. Die Bohrungen lassen sich beispielsweise werks- oder bauseitig unter Verwendung einer Schablone einbringen, sodass ein einheitliches Lochbild bei den miteinander zu verbindenden Bauelementen sichergestellt ist. Vorzugsweise weist das Bauelement mehrere über seine Längserstreckung verlaufende Bohrungen auf, in die freien Enden des Verbindungselementes ragen. Die Anzahl der zu montierenden Verbindungselemente wird im Wesentlichen anhand der statischen Anforderungen an die Verbindung bestimmt. In an embodiment, at least one end face is provided with bores for preloaded receiving the at least one spring toothed disc of the connecting means. The holes can be, for example, factory or on-site introduce using a template, so that a uniform hole pattern is ensured in the interconnected components. Preferably, the component has a plurality of holes extending over its longitudinal extent, projecting into the free ends of the connecting element. The number of fasteners to be mounted is essentially determined by the static requirements of the connection.

Der Rahmen der Erfindung ist nur durch die Ansprüche definiert. It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations. The scope of the invention is defined only by the claims.

Das Verbindungsmittel 1 umfasst einen Bolzen 2, der mehrere gegenläufig wirksame Federelemente 3 in Form von federnden Zungen 1 1 umfasst, die in axialer Richtung weder zueinander noch zu dem Bolzen 2 verschiebbar sind. Die Ausrichtung der Zungen 1 1 ist derart bestimmt, dass sie einer auf den Bolzen 2 wirkenden Auszugskraft entgegenwirken. The connecting means 1 comprises a bolt 2, which comprises a plurality of counteracting spring elements 3 in the form of resilient tongues 1 1, which are displaceable in the axial direction neither to each other nor to the bolt 2.

Die Ausrichtung der Federzahnscheiben 4 ist derart bestimmt, dass sie einer auf den Bolzen 2 wirkenden Auszugskraft entgegenwirken. For connecting two precast concrete elements 6 formed 7 elements on impact holes 7 9 are introduced into the end faces 8 of the components, which have a diameter which is smaller than the clear width of the bolt 2 with the circumferentially protruding spring elements 3, so that the tongues 1 1 under bias in the holes 9 are pressed. To connect two components 7, a plurality of connecting means 1 are first inserted into the corresponding holes 9 of a component 7 and then the next component 7 is pushed onto the free ends of the connecting means 1. In an alternative embodiment, the connecting means 1 comprises the bolt 2 with the spring elements 3 in the form of internally and externally toothed spring toothed disks 4, which are axially fixed to the bolt 2, either in grooves or recesses 12 or by a paragraph 5, that they not in the axial direction to each other or to the pin 2 are displaced. The orientation of the spring pulleys 4 is determined such that they counteract an acting on the pin 2 pull-out force.
Zur Verbindung der Bauelemente 7 auf Stoß werden in die Stirnseiten 8 der Bauelemente 7 die Bohrungen 9 eingebracht, die einen Durchmesser aufweisen, der kleiner als der Außendurchmesser der Federzahnscheiben 4 bemessen ist, sodass die Federzahnscheiben 4 bei der Montage in die Bohrung 9 eingepresst werden. Die Verbindungsmittel 1 werden in die entsprechenden Bohrungen 9 des einen Bauelementes 7 eingesetzt und anschließend wird das nächste Bauelement 7 derart auf die freien Enden der Verbindungsmittel 1 geschoben, dass auch in dessen Bohrung 9 eine Federzahnscheibe 4 des Verbindungsmittels 1 gegen Auszugskräfte wirksam ist. Die im stirnseitigen Anlagebereich vorhandenen Nuten 10 zwischen den benachbarten Bauelementen 7 können mit Beton verfüllt werden. Aufgrund der zwischen zwei Bauelementen 7 wirksamen Verbindungsmittel 1 ist eine Kopplung der Bauelemente 7 gewährleistet, die Zugkräften standhält. To connect the components 7 on impact, the bores 9 are introduced into the end faces 8 of the components 7, which have a diameter which is smaller than the outer diameter of the spring toothed disks 4, so that the spring toothed disks 4 are pressed into the bore 9 during assembly. The connecting means 1 are inserted into the corresponding holes 9 of a component 7 and then the next component 7 is pushed onto the free ends of the connecting means 1, that in the bore 9 a spring toothed disc 4 of the connecting means 1 is effective against pull-out forces. The existing in the frontal investment area grooves 10 between the adjacent components 7 can be filled with concrete. Due to the effective between two components 7 connecting means 1, a coupling of the components 7 is ensured, the tensile forces withstands.
In weiterer alternativer Ausgestaltung ist das Verbindungsmittel 1 als eine Art Nagel ausgebildet und umfasst den Bolzen 2 mit dem Federelement 3 sowie einen endseitigen Kopf 13 mit einem gegenüber dem Bolzen 2 vergrößerten Durchmesser. Gemäß den Ausführungsbeispielen nach den Fig. 5 und 6 ist das eine Bauelement 7 als Beton- fertigteil 6 und das andere Bauelement 7 als ein Stahlwinkel 14 ausgeführt, wobei das Verbindungselement 1 mit seinem Bolzen 2 die Bohrung 9 des Stahlwinkels 14 durchragt und mit seinem Federelement 3 in der Bohrung 9 des Betonfertigteils 6 gehalten ist. Der Kopf 13 des nagelartigen Verbindungsmittels 1 liegt an dem Stahlwinkel 14 an. Das Federelement 3 ist, wie bereits erläutert, entweder durch einen umlaufenden Einstich 12 oder durch einen Absatz 5 in axialer Richtung positioniert. In a further alternative embodiment, the connecting means 1 is designed as a kind of nail and comprises the bolt 2 with the spring element 3 and an end-side head 13 with an opposite the bolt 2 enlarged diameter. According to the embodiments according to FIGS. 5 and 6, this is a component 7 as a concrete finished part 6 and the other component 7 designed as a steel angle 14, wherein the connecting element 1 with its bolt 2, the bore 9 of the steel angle 14 projects through and is held with its spring element 3 in the bore 9 of the precast concrete part 6. The head 13 of the nail-like connecting means 1 abuts against the steel angle 14. The spring element 3 is, as already explained, positioned either by a circumferential recess 12 or by a paragraph 5 in the axial direction.
