Description
Die Erfindung betrifft eine Anordnung zum Bewehren eines Betonbauwerkes gegen Durchstanzen im Bereich der Auflage eines Deckenelementes auf einer Stütze mit einer Mehrzahl von mit seitlichem Abstand zueinander in einer Nahzone seitlich der Stütze gelegener Deckenbereiche in die Decke einzubetonierenden und quer zur Deckenfläche zu orientierenden Ankerelementen sowie Durchstanzbewehrungselementen hierfür.The invention relates to an arrangement for reinforcing a concrete structure against punching in the area of the support of a ceiling element on a support with a plurality of laterally spaced apart in a near zone laterally of the support ceiling areas einzubetonierenden in the ceiling and transverse to the ceiling surface to be oriented anchor elements and punching reinforcement elements for this ,
Bei einer Betondecke, wie einer Gebäudedecke als im Wesentlichen horizontales oder leicht geneigtes Bauteil oder als Unterkonstruktion von aufgestelzten, z.B. verkehrstechnischen Bauwerken, wie bei Rampen oder Brücken für Fahrzeuge jeder Art oder dergleichen treten in der Nahzone seitlich der Stützkonstruktion, wie einer runden oder polygonen Stütze aus Stahl oder Beton oder entsprechenden mauerartigen Gebilden, und insbesondere bei einzeln stehenden Stützpfeilern Durchstanzrisiken auf, d.h., dass die Betondecke in einer Nahzone abriss- und damit einsturzgefährdet ist.In a concrete floor, such as a building ceiling as a substantially horizontal or slightly inclined component or as a substructure of aufgefelzten, such as traffic engineering structures, such as ramps or bridges for vehicles of any kind or the like occur in the Nahzone side of the support structure, such as a round or polygonal support of steel or concrete or corresponding wall-like structures, and in particular for stand-alone buttresses puncture risks, ie that the concrete ceiling in a near zone demolition and thus collapse is at risk.
Es sind eine Reihe von Möglichkeiten bekannt, die Durchstanzgefährdung bei von Stützen getragenen Betonbauwerken zu verringern. Dies kann zum Einen durch eine spezielle Bewehrung der Betondecke im Auflagebereich der Stütze geschehen und zum Anderen in einer Verbreiterung des Stützenkopfes gegenüber dem übrigen Stützenquerschnitt. Eine besonders elegante Lösung für derartige Anwendungsfälle ist in

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine vergleichsweise einfache Bewehrungsanordnung und ein entsprechendes Durchstanzbewehrungselement vorzuschlagen.Based on this, the present invention seeks to propose a comparatively simple reinforcement arrangement and a corresponding punching reinforcement element.
Zur Lösung dieser Aufgabe wird eine Bewehrungsanordnung mit den Merkmalen des Anspruchs 1 sowie ein Durchstanzbewehrungselement mit den Merkmalen des Anspruchs 12 vorgeschlagen.To solve this problem, a reinforcement arrangement with the features of claim 1 and a punching shear reinforcement element with the features of
Die Erfindung basiert demnach auf dem Grundgedanken, mehrere längliche, quer zur Deckenfläche zu orientierende Ankerelemente entlang eines Schubbewehrungselementes auszurichten und somit den gefährdeten Beton-Querschnitt nach Art eines Fachwerkes zu entlasten. Dabei handelt es sich um ein biegesteifes Schubbewehrungselement, das hochkant stehend angeordnet ist, also etwa parallel zu den Ankerelementen, die bevorzugt in Stabform ausgeführt sind. Es wird eine besondere Anordnung der Schubbewehrungselemente derart getroffen, dass sich diese im mittleren Bereich zwischen den Enden der Ankerelemente erstrecken. Die Wirkung dieser besonderen Kombination Schub- und Druckbewehrungselementen wird unten noch weiter erläutert. Die Ankerelemente und das Schubbewehrungselement, entlang dessen die Ankerelemente ausgerichtet sind, können grundsätzlich unverbunden zu einander angeordnet sein, da nach abbinden des Betons dieser eine Wirkverbindung zwischen beiden herstellt. Sie können auch temporär, z.B. durch Draht aneinander befestigt sein. Bevorzugt sind sie allerdings fest miteinander verschweißt. Dadurch werden die höchsten Bewehrungseffekte erzielt und die Verarbeitung deutlich erleichtert. Die Ausrichtung der mehreren Ankerelemente entlang einem hochkant stehenden Schubbewehrungselement kann grundsätzlich einer frei wählbaren Linienführung, wie einer einfachen oder mehrfachen Kurvenform oder entlang eines Polygonzuges erfolgen, solange die Biegesteifigkeit des Schubbewehrungselementes erhalten bleibt. Bevorzugt sind aber die Schubbewehrungselemente gerade gestreckt ausgebildet. Die Ankerelemente können in ihrem seitlichen Abstand zu den Schubbewehrungselementen zwar variieren. Sie liegen vorzugsweise an dem Schubbewehrungselement an. Sie können auf einer oder beiden Seiten des Schubbewehrungselementes angeordnet sein oder das Schubbewehrungselement in sich aufnehmen.The invention is therefore based on the idea of aligning a plurality of oblong, transverse to the ceiling surface to be oriented anchor elements along a shear reinforcement element and thus relieve the vulnerable concrete cross section in the manner of a truss. It is a rigid shear reinforcement element, which is arranged standing upright, that is approximately parallel to the anchor elements, which are preferably designed in rod form. There is a special arrangement of the shear reinforcement elements made such that they extend in the central region between the ends of the anchor elements. The effect of this particular combination shear and pressure reinforcement elements will be further explained below. The anchoring elements and the shear reinforcement element, along which the anchor elements are aligned, can in principle be arranged unconnected to one another, since, after setting of the concrete, this establishes an operative connection between the two. They can also be attached temporarily, eg by wire to each other. Preferably, however, they are firmly welded together. As a result, the highest reinforcement effects are achieved and processing is greatly facilitated. The orientation of the plurality of anchor elements along an upright shear reinforcement element can basically be a freely selectable lines, such as a single or multiple waveform or along a polygon, as long as the bending stiffness of the shear reinforcement element is maintained. Preferably, however, the shear reinforcement elements are designed straight stretched. Although the anchor elements may vary in their lateral distance to the shear reinforcement elements. They are preferably on the shear reinforcement element. They can be arranged on one or both sides of the shear reinforcement element or receive the shear reinforcement element in itself.
Um höchst mögliche Durchstanzbewehrung zu erzielen werden mehrere Schubbewehrungselemente mit den zugehörenden Druckbewehrungs- oder Ankerelementen sternen- oder strahlenförmig bezüglich der Stütze in deren Nahzone sie in der Decke anzuordnen sind, ausgerichtet.In order to achieve the highest possible punching shear reinforcement several shear reinforcement elements with the associated Druckbewehrungs- or anchor elements are starry or radial with respect to the support in the near zone they are to be arranged in the ceiling aligned.
Es hat sich herausgestellt, dass durch die Erfindung der Schubwiderstand im gefährdeten Schnitt deutlich erhöht werden kann. Auch die Druckfestigkeit im Bereich der Nahzone wird durch die Erfindung deutlich verbessert. Die erfindungsgemäße Kombination und gegenseitige Zuordnung der Schub- und Druckbewehrungselemente führt zu einer nicht erwartet hohen Versteifung und Verringerung der Durchstanzrisiken in der Unterstützungszone und darüber hinaus.It has been found that the thrust resistance in the vulnerable section can be significantly increased by the invention. The compressive strength in the region of the near zone is also significantly improved by the invention. The inventive combination and mutual assignment of the shear and compression reinforcement elements leads to an unexpectedly high stiffening and reduction of punching risks in the support zone and beyond.
Bei einer bevorzugten Ausführungsform werden als biegesteife, hochkant stehende Schubbewehrungselemente Bleche bzw. Blechstreifen verwendet, diese werden bevorzugt parallel zu einer von den Ankerelementen aufgespannten Bezugsebene angeordnet. Dieses Schubbewehrungselement kann auch diagonal zur Ausrichtung der Ankerelemente orientiert sein, wobei die Steigung zwischen dem Schubbewehrungselement und der Erstreckungsrichtung der Bewehrungsanordnung zwischen 10 und 100% und besonders bevorzugt in der Größenordnung von 45% liegen kann. Um den Betonverbund im Bereich blechstreifenförmiger oder in anderer Weise flächiger Schubbewehrungselemente zu erhöhen, werden die Schubbewehrungselemente mit mindestens einer fensterartigen Durchbrechung versehen.In a preferred embodiment, sheets or metal strips are used as rigid, upright shear reinforcement elements, these are preferably arranged parallel to a plane spanned by the anchor elements reference plane. This shear reinforcement element can also be oriented diagonally to the orientation of the anchor elements, wherein the pitch between the shear reinforcement element and the extension direction of the reinforcement arrangement between 10 and 100%, and particularly preferably in the order of 45%. In order to increase the concrete composite in the area sheet-metal strip-shaped or otherwise flat shear reinforcement elements, the shear reinforcement elements are provided with at least one window-like opening.
Als Ankerelemente kommen bevorzugt und wie zumindest teilweise an sich bekannt Doppelkopfanker, Bügelanker oder hochfeste Verbundanker, insbesondere Ringbügelanker in Betracht. Doppelkopfanker bestehen aus einem Ankerbolzen und an dessen Enden vorgesehenen Ankerköpfen, vergleichsweise größeren Querschnitts. Auch die Bügelanker weisen eine längliche Form auf, wobei bügelartige Verbindungsbereiche zwischen parallelen gerade gestreckten Bereichen die Funktion eines Ankerkopfes übemehmen. Hochfeste Verbundanker weisen bekannte über die Stablänge verteilte, markante Profilierungen in unterschiedlichen Gestaltungen auf.As anchoring elements are preferred and as at least partially known per se double head anchor, bar anchors or high-strength composite anchor, in particular ring hoop anchor into consideration. Double-headed anchors consist of an anchor bolt and provided at the ends anchor heads, relatively larger cross-section. Also the Bügelanker have an elongated shape, wherein bow-like connecting portions between parallel straight elongated areas take over the function of an anchor head. High-strength composite anchors have known distributed over the rod length, distinctive profiles in different designs.
Insbesondere bei Decken, die eine zur Horizontale geneigte Fläche aufweisen, können die Ankerelemente auch schräg angeordnet sein, d. h. unter einem Winkel zur Vertikalen. Dieser Winkel kann größer als etwa 1° sein, vorzugsweise kann dieser Winkel zur Vertikalen kleiner als etwa 45° sein. In einer besonders bevorzugten Ausführung beträgt der Winkel zwischen den Ankerelementen und der Vertikalen etwa 20°. Durch die Neigung der Ankerelemente gegenüber der Vertikalen wird die statische Eigenschaft der erfindungsgemäßen Bewehrungsanordnung insbesondere bei Decken, deren Flächen zumindest eine Neigung aufweisen, verbessert. Wahlweise können die Ankerelemente auch lotrecht in der geneigten Deckenfläche angeordnet werden. Es ist ferner möglich, die Ankerelemente schräg, d. h. mit einer Neigung relativ zur Vertikalen in einer horizontal ausgerichteten Decke anzuordnen. Die betrifft auch Decken, deren Deckenflächen keine Neigung relativ zur Horizontalen aufweisen.In particular, in the case of ceilings which have an inclined surface to the horizontal, the anchor elements may also be arranged obliquely, d. H. at an angle to the vertical. This angle may be greater than about 1 °, preferably this angle to the vertical may be less than about 45 °. In a particularly preferred embodiment, the angle between the anchor elements and the vertical is about 20 °. Due to the inclination of the anchor elements relative to the vertical, the static property of the reinforcement arrangement according to the invention is improved, in particular for ceilings whose surfaces have at least one inclination. Optionally, the anchor elements can also be arranged vertically in the inclined ceiling surface. It is also possible, the anchor elements obliquely, d. H. to arrange with a slope relative to the vertical in a horizontally oriented ceiling. This also applies to ceilings whose ceiling surfaces have no inclination relative to the horizontal.
Eine besonders vorteilhafte Einspannung des Durchstanzbewehrungselementes, insbesondere im Bereich seines stützenseitigen Endes, können Endverankerungsmittel vorgesehen sein. Dies geschieht besonders vorteilhaft in Gestalt von die Schubbewehrungselemente seitlich überragende Bolzen, z.B. durchgesteckte und/oder angeschweißte Rundeisen in einer oder mehreren Höhenbereichen u. a. wie aus der
