Description

Die Erfindung geht von einem Fertigteilverband für Stützmauern, Schallschutzmauern u. dgl. Bauwerke aus, bestehend aus in der Mauerebene scharenweise längsverlaufend und mit ihren Enden im Wechsel übereinanderliegend verlegten Läuferelementen und an deren Enden ansetzenden, senkrecht zu diesen Läuferelementen in ein Hinterfüllungsmaterial verlaufenden Binderelementen, die miteinander in Verbindung stehende Hohlräume aufweisen bzw. einschließen, die sich zwecks Verbindung der Läufer- und Binderelemente über die Höhe des Fertigteilverbandes erstrecken.The invention relates to a prefabricated structure for retaining walls, soundproof walls and. Buildings made up of, consisting of groups of runners that run lengthwise in the wall plane and with their ends alternately superimposed on one another, and at their ends, perpendicular to these runner elements that run into a backfill material and that have or include interconnected cavities that enclose each other extend over the height of the prefabricated structure to connect the runner and binder elements.

Ein solcher Fertigteilverband ist in der britischen Patentschrift 1552623 beschrieben und besteht aus mit etwa gleich großem rechteckquerschnitt profilierten Läufer- und Binderelementen mit in Abständen angeordneten vertikalen Ausnehmungen zur Unterbringung von Verbindungselementen, die die Fertigteile durchsetzen und mit deren Hilfe dem Fertigteilverband der wünschenswerte Zusammenhalt vermittelt wird. Dieser Zusammenhalt ist jedoch insofern fragwürdig als er weitgehend von der Zugfestigkeit und der Korrosionsfestigkeit der aus Drahtseilen od. dgl. bestehenden Verbindungsorgane abhängig ist und die Läufer- und Binderelemente im übrigen lediglich mit Reibungsschluß aufeinanderliegen. Dazu kommt, daß die sehr massiven, balkenförmigen Fertigteile des vorbekannten Fertigteilverbandes mit ihrem hohen Gewicht das Fundament sehr stark belasten und dieser Fertigteilverband deshalb zu ungleichmäßigen Setzungen neigt.Such a prefabricated assembly is described in British Patent Specification 1552623 and consists of runner and binder elements with approximately the same size rectangular cross-section, with spaced vertical recesses for accommodating connecting elements which penetrate the prefabricated parts and with the help of which the prefabricated assembly is imparted the desired cohesion. However, this cohesion is questionable insofar as it is largely dependent on the tensile strength and the corrosion resistance of the connecting elements made of wire ropes or the like, and the runner and binder elements only rest on one another with frictional engagement. In addition, the very massive, bar-shaped prefabricated parts of the known prefabricated structure with their high weight put a heavy load on the foundation and this prefabricated structure therefore tends to uneven settlement.

Aufgabe vorliegender Erfindung ist die Schaffung eines Fertigteilverbandes, der aus wesentlich leichteren Fertigteilen besteht, die gemeinsam mit einer Ortbetonfüllung monolithisch zusammenfügbar sind und sodann dank einer zielstrebigen Gestaltung und Bemessung bei vergleichsweise geringem Betonbedarf einen besonders innigen Zusammenhalt des Verbandes gewährleisten.The object of the present invention is to create a prefabricated assembly which consists of much lighter prefabricated parts which can be assembled monolithically together with in-situ concrete filling and then, thanks to a purposeful design and dimensioning with a comparatively low need for concrete, ensure a particularly intimate cohesion of the association.

Diese Aufgabe wird den wesentlichsten Erfindungsmerkmalen zufolge dadurch gelöst, daß bei einem Fertigteilverband der eingangs definierten Gattung die Läuferelemente winkelförmig profiliert und mit einem in der Mauerebene stehenden Schenkel verlegt sind, wobei die Binderelemente zwischen den liegenden Schenkeln der Enden jeweils überelnanderliegender Läufereiemente im Bereich dort angeordneter Ausnehmungen in den Verband einbinden und mit gegebenenfalls bewehrtem Ortbeton füllbare Hohlräume einschließen.This object is achieved according to the most important features of the invention in that in a prefabricated assembly of the type defined at the outset, the rotor elements are profiled at an angle and laid with a leg standing in the plane of the wall, the binder elements between the lying legs of the ends of the respective running elements in the area of recesses arranged there Integrate into the dressing and enclose cavities that can be filled with reinforced concrete, if necessary.

Auf diese Weise werden im Bereich der übereinanderliegenden Enden der Fertigteile des Verbandes Steher besonderer Festigkeit gebildet, die über die gesamte Höhe des Verbandes verlaufen, zur Steifigkeit außerordentlich beitragen und diesem Verband eine hohe Widerstandsfähigkeit gegen eine durch den Druck des Hinterfüllungsmateriales verursachte Formänderung verleihen. Dank der monolithischen Verbindung der Fertigteile bildet der Verband ein nicht nur steifes, sondern mit den Binderelementen auch sehr zuverlässig in der Hinterfüllung rechenartig verankertes Raumgitter, das sich in dieser Hinterfüllung verzahnt und verkrallt, gleichzeitig aber auch in der Wandebene eine hohe Flächensteifigkeit aufweist.In this way, pillars of particular strength are formed in the region of the ends of the finished parts of the association, which extend over the entire height of the association, make an extraordinary contribution to rigidity and give this association a high resistance to a change in shape caused by the pressure of the backfill material. Thanks to the monolithic connection of the prefabricated parts, the dressing not only forms a rigid, but also with the binder elements very reliably anchored in the backfill space grid, which interlocks and claws in this backfill, but at the same time has a high surface rigidity in the wall plane.

Der erfindungsgemäße Fertigteilverband kann ferner in zeitlich voneinander getrennten Phasen, demnach auch durch verschieden spezialisierte Arbeitspartien errichtet werden. Es kann zunächst eine Montage und gegebenenfalls Verankerung der Fertigteile selbst erfolgen und der fertiggestellte Verband kann zu einem beliebigen späteren Zeitpunkt mit Ortbeton gefüllt und mit Material hinterfüllt werden. Weiters ist der Fertigteilverband ohne Schwierigkeit auch gekrümmt verlegbar, ohne daß es hiefür einer Sonderanfertigung von Fertigteilen bedarf. Die Ortbetonfüllung im Bereich der Fertigteil-Enden erfordet keine exakte Übereinstimmung der Querschnitte der in diesen Fertigteilen vorgesehenen Hohlräume, sondern es genügt, wann diese Hohlräume mit ihren Querschnitten bloß annähernd fluchten.The prefabricated structure according to the invention can also be set up in phases that are separated from one another in time, and therefore also by differently specialized work parties. The prefabricated parts can be assembled and anchored, if necessary, and the finished bandage can be filled with in-situ concrete and backfilled with material at any later point in time. Furthermore, the prefabricated structure can also be laid in a curved manner without difficulty, without the need for special manufacture of prefabricated parts. The in-situ concrete filling in the area of the prefabricated ends does not require an exact match of the cross sections of the cavities provided in these prefabricated parts, but it is sufficient when these cavities are only approximately aligned with their cross sections.

Vorteilhafterweise besitzen die liegenden Schenkel der Läuferelemente kreisrunde Ausnehmungen, damit auch Bauwerke mit gekrümmter Sichtfläche errichtet werden können, die dann in den Bereichen der aufeinanderliegenden Enden der Fertigteile stumpfe Ecken bilden.Advantageously, the lying legs of the runner elements have circular recesses, so that structures with a curved visible surface can also be erected, which then form blunt corners in the regions of the ends of the prefabricated parts lying on top of one another.

Die Binderelemente sind zweckmäßigerweise rahmenförmig gestaltet, schließen einen Hohlraum ein, dessen lichte Breite etwa der Größe der Ausnehmungen der Läuferelemente entspricht, und sind derart in den Fertigteilverband eingebunden, daß diese Ausnehmungen der liegenden Schenkel der Läuferelemente innerhalb des lichten Querschnittes der Hohlräume zu liegen kommen.The binder elements are expediently frame-shaped, enclose a cavity, the clear width of which corresponds approximately to the size of the recesses of the rotor elements, and are integrated into the prefabricated structure in such a way that these recesses of the lying legs of the rotor elements come to lie within the clear cross section of the cavities.

For the sake of clarity, further features of the invention are explained below on the basis of an exemplary embodiment of the invention which is illustrated in the drawings. In these drawings shows
  • FIG. 1 shows a longitudinal view of the prefabricated assembly,
  • FIG. 2 shows a top view,
  • 3 shows a cross section according to 111-111 of FIG. 2,

Gemäß der Darstellungen besteht der Fertigteilverband aus den in der Mauerebene scharenweise längsverlaufend verlegten, winkelförmig profilierten Läuferelementen 1 und aus den rahmenförmig ausgebildeten, an die übereinanderliegenden und einander überlappenden Enden der Läuferelemente 1 senkrecht ansetzenden Binderelementen 2.According to the diagrams, the prefabricated structure consists of the sheets, which are laid lengthways in the wall level, Angularly profiled rotor elements 1 and from the frame-shaped binder elements 2 which are vertically attached to the superimposed and overlapping ends of the rotor elements 1.

Die Läuferelemente 1 weisen einen in der Mauerebene stehenden Schenkel 1' und einen senkrecht zur Mauerebene liegenden Schenkel 1" auf und besitzen an ihren beiden Enden kreisrunde Ausnehmungen 3 in ihrem liegenden Schenkel 1". Die rahmenförmig gestalteten Binderelemente schließen Hohlräume 4 ein und binden mit ihren Enden zwischen den liegenden Schenkeln 1" der Läuferelemente 1 senkrecht in den Fertigteilverband ein.The rotor elements 1 have a leg 1 ′ standing in the wall plane and a leg 1 ″ lying perpendicular to the wall plane and have circular recesses 3 in their lying leg 1 ″ at their two ends. The frame-shaped binder elements enclose cavities 4 and bind vertically into the prefabricated structure with their ends between the lying legs 1 "of the rotor elements 1.

Die über ihren Längsverlauf satt aufeinanderliegenden Binderelemente 2 weisen eine Höhe auf, die der vollen Höhe des aufrechten Schenkels 1' der Läuferelemente 1 entspricht, doch besitzen sie im Endbereich eine vorzugsweise unterseitige Absetzung 5, deren Länge der innen gemessenen Länge des liegenden Schenkels 1" und deren Höhe der Dicke dieses liegenden Schenkels 1" der Läuferelemente 1 entspricht. Der Abstand der in diesem liegenden Schenkel 1" der Läuferelemente 1 vorgesehenen Ausnehmung 3 von der Innenseite des stehenden Schenkels 1' ist annähernd gleich der Dicke jener Wandung des rahmenförmigen Binderelementes 2, das jeweils an der Innenseite des stehenden Schenkels 1' des Läuferelementes 1 anliegt. Infolgedessen kommen die Ausnehmungen 3 der liegenden Schenkel 1" der Läuferelemente 1 innerhalb der lichten Querschnitte der Hohlräume 4 der Binderelemente 2 zu liegen und es bilden sich im Bereich der Enden der übereinanderliegenden Fertigteile 1 und 2 Scharen kommunizierender Hohlräume, die dann zur Herstellung steifer Steher mit bewehrem Ortbeton gefüllt werden können.The binder elements 2, which lie one on top of the other along their longitudinal course, have a height which corresponds to the full height of the upright leg 1 'of the runner elements 1, but in the end region they have a preferably underside shoulder 5, the length of which is measured on the inside of the lying leg 1 "and whose height corresponds to the thickness of this lying leg 1 "of the rotor elements 1. The distance of the recess 3 provided in this leg 1 "of the runner elements 1 from the inside of the standing leg 1 'is approximately equal to the thickness of that wall of the frame-shaped binder element 2, which lies against the inside of the standing leg 1' of the runner element 1. As a result, the recesses 3 of the lying legs 1 ″ of the rotor elements 1 come to lie within the clear cross sections of the cavities 4 of the binder elements 2 and, in the region of the ends of the superimposed finished parts 1 and 2, groups of communicating cavities are formed, which are then used to produce rigid uprights reinforced in-situ concrete can be filled.

Wie die Figur 7 erkennen läßt, tritt dieser Vorteil auch dann ein, wenn die Läuferelemente 1 - bei gekrümmten Bauwerken - in einem Winkel bis zu etwa 20° zueinander verlaufen.As can be seen in FIG. 7, this advantage also occurs when the rotor elements 1 - in the case of curved structures - run at an angle of up to approximately 20 ° to one another.

Vorteilhafterweise kann im Rahmen der Erfindung die Länge der Läuferelemente 1 so gewählt werden, daß sie der üblichen Länge von Straßenleitschienen angemessen ist. In diesem Fall kann für den oberen Abschluß einer Stützmauer eines Verkehrsweges ein serienmäßiges Element Verwendung finden, das die Ausbildung eines Gehsteiges bzw. die Anbringung von Leitschienenpfosten 7 und Leitschienen 8 ermöglicht und erleichtert. Zur Begrenzung solcher Verkehrswege 9 kann auch ein Geländer 10 angeordnet werden. Dies ist in der Figur 3 beispielsweise veranschaulicht.Advantageously, the length of the rotor elements 1 can be selected within the scope of the invention so that it is appropriate for the usual length of road guide rails. In this case, a standard element can be used for the upper end of a retaining wall of a traffic route, which enables and facilitates the formation of a sidewalk or the mounting of guard rail posts 7 and guard rails 8. A railing 10 can also be arranged to limit such traffic routes 9. This is illustrated in FIG. 3, for example.

Um zu verhindern, daß die Läuferelemente 1 durch die Lagerung im Stapel mit den Binderelementen 2 so weitgehend eingespannt wélarden, daß dadurch das statische System des Fertigteilverbandes unbestimmt wird, ist zweckmäßigerweise vorgesehen, daß zwischen den Auflagerflächen der Läufer- und Binderelemente verformbare und/oder reibungsmindernde Zwischenlagen 11, z. B. Dämmfilze, angeordnet sind. Diese Zwischenlagen 11 weisen notwendigerweise Ausnehmungen auf, die mit den Ausnehmungen 3 der Läuferelemente 1 konform sind. Als weiterer Vorteil solcher Zwischenlagen 11 ergibt sich, daß die Paßgenauigkeit der Fertigteilverbindungen beim Zusammenbau der Fertigteile durch diese Zwischenlagen 11 gefördet wird.In order to prevent the runner elements 1 from being so largely clamped by the storage in the stack with the binder elements 2 that the static system of the prefabricated assembly is thereby indefinite, it is expediently provided that deformable and / or friction-reducing between the bearing surfaces of the runner and binder elements Intermediate layers 11, z. B. insulation felts are arranged. These intermediate layers 11 necessarily have recesses which conform to the recesses 3 of the rotor elements 1. Another advantage of such intermediate layers 11 is that the fit of the precast connections during assembly of the finished parts is promoted by these intermediate layers 11.
