Abstract

The invention relates to a concrete structure consisting of at least two precast-concrete wall elements (1) that are positioned next to one another. This structure is to be developed further in such a manner that a form-fit is already produced at the joining stage so that a continued retention of the individual precast-concrete wall elements, up until their definitive interconnection, is not required. It is suggested that the precast-concrete wall element (1) has, on at least one of its sides which is joined to a further precast-concrete wall element (V), a first region comprising a projection (2); that a second region of this side comprises a recess (3) for receiving the projection (2') of the first region of a second precast-concrete wall element (1'); and that these precast-concrete wall elements (1, 1', 1n) are joined together, offset to one another, at the height of these respective regions.

Description

Betonkonstruktionen  concrete structures
Die Erfindung betrifft eine Betonkonstruktion, bestehend aus mindestens zwei nebeneinander positionierten Fertigbeton-Wandelementen. The invention relates to a concrete structure consisting of at least two juxtaposed precast concrete wall elements.
Derartige Betonkonstruktionen können aus Fertigbeton-Wandelementen zusammengesetzte Schutzwände, aber auch Wände von Behältern, Gebäuden oder Türmen sein. Such concrete structures can be made of precast concrete wall elements composed protective walls, but also walls of containers, buildings or towers.
Die EP 2 239 398 A 1 offenbart beispielsweise einen aus derartigen Fertigbeton- Wandelementen hergestellten Turm. Hier werden die Fertigbeton-Wandelemente in Kletterbauweise aneinandergefügt. Das Fügen selbst ist jedoch noch problematisch, da die einzelnen losen Elemente so lange gehalten werden müssen, bis eine Verbindung mit den bereits stehenden Fertigbeton-Wandelementen hergestellt worden ist. For example, EP 2 239 398 A1 discloses a tower made of such prefabricated concrete wall elements. Here, the precast concrete wall elements are joined together in climbing construction. The joining itself, however, is still problematic because the individual loose elements must be kept until a connection has been established with the already existing precast concrete wall elements.
Die FR 1 175 248 A offenbart ebenfalls Fertigbeton-Wandelemente, die in Kletterbauweise aneinandergefügt werden. Hier weisen die Fertigbeton-Wandelemente an ihren Seiten Ösen auf. Die Ösen zweier Wandelemente werden zur Deckung gebracht und über Armierungsstäbe miteinander verbunden. Damit wird zwar erreicht, dass die Fertigbeton-Wandelemente miteinander verbunden sind, ein Formschluss wird jedoch erst erreicht, wenn die Fuge mit Frischbeton ausgefüllt ist und der Beton abgebunden hat. The FR 1 175 248 A also discloses precast concrete wall elements which are joined together in climbing construction. Here, the precast concrete wall elements have eyelets on their sides. The eyelets of two wall elements are brought to coincidence and connected by reinforcing rods. Although this ensures that the precast concrete wall elements are connected to each other, but a positive connection is only achieved when the joint is filled with fresh concrete and the concrete has set.
Die CH 409 343 A offenbart bereits Stahlbeton-Fertigteile, die zu einem Behälter zusammengesetzt werden können. Im Bereich der Verbindungsfugen weist das Stahlbeton-Fertigteil an einer Seite von einer Wandfläche ausgehend über die gesamte Höhe einen Ansatz auf, während an der gleichen Seite, jedoch von der gegenüberliegenden Wandfläche ausgehend eine entsprechende Ausnehmung über die gesamte Höhe des Stahlbetons-Fertigteils vorgesehen ist. Auch hier müssen die Wandelemente so lange gehalten werden, bis sie über Armierungsstäbe miteinander verbunden sind und der in die Fugen gegossene Frischbeton ausgehärtet ist. The CH 409 343 A discloses already reinforced concrete precast parts that can be assembled into a container. In the area of connecting joints, the Precast reinforced concrete element on one side of a wall surface starting over the entire height of an approach, while on the same side, but provided from the opposite wall surface starting a corresponding recess over the entire height of the reinforced concrete precast element. Again, the wall elements must be kept until they are connected to each other via reinforcing bars and the poured into the joints of fresh concrete is cured.
Der Erfindung liegt die Aufgabe zugrunde, eine Betonkonstruktion derart weiterzubilden, dass schon beim Fügen ein Formschluss erfolgt, der ein weiteres Halten der einzelnen Fertigbeton-Wandelemente bis zum endgültigen Verbinden derselben miteinander erübrigt. The invention has the object of providing a concrete construction in such a way that even when joining a positive connection takes place, which makes it unnecessary to further hold the individual precast concrete wall elements until the final connection of the same.
Zur Lösung dieser Aufgabe wird vorgeschlagen, dass das Fertigbeton- Wandelement an mindestens einer seiner mit einem weiteren Fertigbeton- Wandelement zusammengefügten Seiten einen ersten Höhenbereich mit einem Ansatz aufweist und dass ein zweiter Höhenbereich der Seite eine Ausnehmung zur Aufnahme des Ansatzes des ersten Bereichs einen zweiten Fertigbeton- Wandelements besitzt und dass die Fertigbeton-Wandelemente in Höhe der jeweiligen Bereiche versetzt zueinander zusammengefügt sind. To solve this problem, it is proposed that the precast concrete wall element on at least one of its assembled with another prefabricated concrete wall element sides has a first height range with a lug and that a second height range of the side of a recess for receiving the approach of the first area a second precast concrete - Has wall element and that the precast concrete wall elements are joined together at the level of the respective areas offset.
Die Ansätze eines Fertigbeton-Wandelements passen dabei komplementär mit den Ausnehmungen eines zweiten Fertigbeton-Wandelements zusammen. Sind bereits mehrere Fertigbeton-Wandelemente zusammengefügt, so lässt sich ein weiteres Element in die zwischen den Elementen bestehende, in der Höhe versetzte Fuge einfügen. Dabei wird das neu eingesetzte Fertigbeton-Wandelement auf eine waagerechte Seite eines unteren Fertigbeton-Wandelements aufgesetzt und an die in der Lücke hineinreichenden Ansätze der bereits stehenden Fertigbeton-Wandelemente angelehnt. Zusätzlich besteht die Möglichkeit, dass sich die Ansätze des neu eingefügten Fertigbeton-Wandelementes mit ihren unteren Kanten auf den oberen horizontalen Seiten der bereits stehenden Fertigbeton-Wandelemente abstützen. Das so neu eingesetzte Fertigbeton-Wandelement steht durch die AbStützungen in vertikaler und horizontaler Richtung verhältnismäßig stabil, so dass regelmäßig nur noch eine Kippsicherung notwendig ist. Dadurch lässt sich das neu eingesetzte Fertigbeton-Wandelement ohne weiteres Fügen und Anschließen miteinander verbinden. The projections of a precast concrete wall element fit together in a complementary manner with the recesses of a second precast concrete wall element. If several prefabricated concrete wall elements are already joined together, another element can be inserted into the vertically offset joint between the elements. The newly used precast concrete wall element is placed on a horizontal side of a lower precast concrete wall element and leaned against the reaching into the gap approaches the already existing ready-mixed concrete wall elements. In addition, there is the possibility that the approaches of the newly inserted precast concrete wall element are supported with their lower edges on the upper horizontal sides of the already existing precast concrete wall elements. The newly used ready-mixed concrete wall element is relatively stable by the supports in the vertical and horizontal directions, so that regularly only a tilt protection is necessary. As a result, the newly used precast concrete wall element can be connected to one another without further joining and connection.
Von Vorteil ist, dass der Ansatz von einer der Wandflächen des Fertigbeton- Wandelementes ausgehend im Wesentlichen die halbe Dicke bis maximal die Dicke des Fertigbeton-Wandelements aufweist und dass die Ausnehmung im Bereich der gleichen Wandfläche vorgesehen ist und in ihrer Tiefe im Wesentlichen der halben Dicke bis maximal der Dicke des Fertigbeton-Wandelements entspricht. It is advantageous that the approach of one of the wall surfaces of the precast concrete wall element starting substantially half the thickness to a maximum of the thickness of the precast concrete wall element and that the recess is provided in the region of the same wall surface and in depth substantially half the thickness to a maximum of the thickness of the precast concrete wall element corresponds.
Durch diese Maßnahme wird erreicht, dass mehrere Fertigbeton-Wandelemente zusammengefügt werden können, ohne dass es zu einem Sprung in der Dicke der Betonkonstruktion in deren Nahtbereichen kommt. By this measure it is achieved that several precast concrete wall elements can be joined together, without causing a jump in the thickness of the concrete structure in the seam areas.
Zweckmäßig ist, dass der Ansatz und die Ausnehmung jeweils im Wesentlichen der halben Höhe der Fertigbeton-Wandelemente entsprechen. Dadurch ist der Zusammenbau der Fertigbeton-Wandelemente zu einer Betonkonstruktion besonders einfach und zügig zu bewerkstelligen. It is expedient that the projection and the recess each correspond substantially to half the height of the precast concrete wall elements. As a result, the assembly of the precast concrete wall elements to a concrete structure is particularly easy and quick to accomplish.
Obwohl in dem Bereich, in dem die Fertigbeton-Wandelemente auf ein Fundament gesetzt werden, oder im oberen Endbereich einer Betonkonstruktion durchaus Lücken verbleiben können, ist es sinnvoll, diese zu schließen. Dazu wird vorgeschlagen, dass zweite Fertigbeton-Wandelemente vorgesehen sind, welche im Wesentlichen die Höhe der Ausnehmungen aufweisen und die über ihre Höhe mit einem Ansatz versehen sind, und dass dritte Fertigbeton-Wandelemente vorgesehen sind, welche im Wesentlichen die Höhe der Ansätze aufweisen und die über ihre Höhe mit Ausnehmungen versehen sind. Although gaps may still remain in the area where the precast concrete wall elements are placed on a foundation, or in the upper end of a concrete structure, it makes sense to close them. For this purpose, it is proposed that second prefabricated concrete wall elements are provided, which essentially have the height of the recesses and with their height an approach are provided, and that third prefabricated concrete wall elements are provided which have substantially the height of the lugs and which are provided over their height with recesses.
Mit diesen in der Regel halben Höhen der Fertigbeton-Wandelemente lassen sich ohne Weiteres die Lücken, welche beim Aufbau der Fertigbeton-Wandelemente auf einem Fundament entstehen würden, und die auch am oberen Ende z. B. eines Turms entstehen, schließen. With these usually half the height of the precast concrete wall elements can be readily the gaps that would arise in a construction of the precast concrete wall elements on a foundation, and also at the upper end z. B. a tower, close.
Zum Bilden von aus geraden Wänden bestehenden Betonkonstruktionen ist es sinnvoll, die Ansätze in einer Ebene mit den Außenflächen der Fertigbeton- Wandelemente auszuführen. Sollen jedoch mehreckige Betonkonstruktionen erstellt werden, ist es sinnvoll, dass die Ansätze winklig von den Fertigbeton- Wandelementen abstehen. Dabei ist der Winkel frei wählbar, ergibt sich jedoch in der Regel an der Anzahl der geplanten Ecken, um einen Behälter, ein Gebäude oder einen Turm von allen Seiten zu schließen To form concrete walls made of straight walls, it makes sense to make the lugs in a plane with the outer surfaces of the precast concrete wall elements. However, if polygonal concrete structures are to be created, it makes sense that the lugs project at an angle from the precast concrete wall elements. The angle is freely selectable, but usually results in the number of corners planned to close a container, a building or a tower from all sides
Bedeutsam ist, dass die gefügten Fertigbeton-Wandelemente zumindest im Bereich der Überlappung von Ansatz und Ausnehmung kraftschlüssig miteinander verbunden sind. Hier lassen sich Kleber, aber auch mechanische Verbindungen denken, wobei der Kleber zwischen Ansatz und Ausnehmung z. B. in Form von Frischbeton gewählt werden kann. Es besteht aber auch die Möglichkeit, durch Schraubverbindungen oder andere mechanische Verbindungsmittel die Fertigbeton-Wandelemente untereinander zu verbinden. It is important that the joined precast concrete wall elements are non-positively connected to each other at least in the overlap of the neck and recess. Here you can think glue, but also mechanical connections, the adhesive between approach and recess z. B. can be selected in the form of fresh concrete. But it is also possible to connect by screw or other mechanical connection means the precast concrete wall elements with each other.
Eine noch bessere Einleitung und Übernahme von Kräften in verschiedene Richtungen wird erreicht, wenn die Ansätze in ihrem, den Ausnehmungen zugewandten Bereich, mit Federn und / oder Nuten versehen sind und die die Ausnehmungen begrenzenden Bereiche der Fertigbeton-Wandelemente, komplementäre Nuten und / oder Federn aufweisen. Die Erfindung wird anhand einer Zeichnung näher erläutert: Dabei zeigt: An even better introduction and takeover of forces in different directions is achieved when the lugs are provided in their, the recesses facing area, with springs and / or grooves and the recesses delimiting areas of the precast concrete wall elements, complementary grooves and / or springs exhibit. The invention will be explained in more detail with reference to a drawing, in which:

Figur 1 zeigt ein Fertigbeton-Wandelement 1 , welches im Bereich seiner oberen Hälfte mit Ansätzen 2, 2' ausgestattet sind. Die Ansätze sind hier z. B. in einem Winkel von 45° angeordnet, so dass sich insgesamt eine achteckige Konstruktion ergeben würde. Andere Winkel sind selbstverständlich denkbar, wobei die Winkel, je kleiner die Anzahl der geplanten Ecken ist, größer werden. Je größer die Anzahl der geplanten Ecken der Betonkonstruktion ist, je kleiner werden die entsprechenden Winkel. Figure 1 shows a precast concrete wall element 1, which are in the region of its upper half with lugs 2, 2 'are equipped. The approaches are here z. B. arranged at an angle of 45 °, so that an octagonal construction would result in total. Other angles are of course conceivable, the angles being smaller, the smaller the number of planned corners, becoming larger. The larger the number of planned corners of the concrete structure, the smaller the corresponding angles.
Im unteren Bereich des Fertigbeton-Wandelements 1 weist dieses Ausnehmungen 3, 3" auf. Sollen mehrere Fertigbeton-Wandelemente 1 z. B. zu einem Turm zusammengesetzt werden, so würde vor einen Ansatz 2 eines Fertigbeton- Wandelementes 1 eine Ausnehmung 3' eines zweiten Fertigbeton- Wandelementes vorgesetzt. This recess 3, 3 "is located in the lower area of the precast concrete wall element 1. If a plurality of precast concrete wall elements 1 are to be assembled into a tower, for example, a recess 3 'of a second one would be provided in front of a projection 2 of a precast concrete wall element 1 Precast concrete wall element preset.
