Description

Die Erfindung betrifft die Ausbildung der Ecke einer Abfangmauer aus zwei L-förmigen Betonsteinen, welche jeweils aus einer aufrechten Mauerscheibe und einer von dieser im rechten Winkel abstehenden waagerechten Fußscheibe bestehen und aneinandergefügt sind.The invention relates to the formation of the corner of an interception wall made of two L-shaped concrete blocks, each of which consists of an upright wall plate and a horizontal base plate protruding therefrom at right angles and are joined together.

Die DE-PS 32 32 799 zeigt bereits die Ausbildung einer Abfangmauer aus L-förmigen Betonsteinen, deren aufrechte Mauerscheiben halbzylindrisch gerundete Seitenflächen haben. Dadurch ist es möglich, geschwungene Abfangmauern herzustellen, bei denen die Stoßfugen zwischen aneinanderstoßenden Mauerscheiben infolge der Rundung ihrer Seitenflächen unabhängig vom Winkel, unter dem sie zusammenstoßen, im wesentlichen gleich gut aussehen.DE-PS 32 32 799 already shows the formation of an interception wall made of L-shaped concrete blocks, the upright wall discs of which have semi-cylindrical rounded side surfaces. This makes it possible to produce curved retaining walls in which the butt joints between adjoining wall panels look essentially equally good due to the curvature of their side surfaces, regardless of the angle at which they meet.

In der Praxis kommen jedoch häufig Verläufe von Abfangmauern vor, in denen geradlinige Abschnitte unter einem gewissen Winkel aufeinanderstoßen. Für geradlinige Abschnitte werden aber nach wie vor L-förmige Betonsteine bevorzugt, bei denen die schmalen Seitenflächen der aufrechten Mauerscheiben ebenflächig sind und im rechten Winkel zur Vorderseite der Mauerscheibe verlaufen, denn dadurch erhält die Abfangmauer ein geschlosseneres Aussehen und die Gefahr, daß Erdreich von der Rückseite der Mauer durch die Fuge zwischen zwei benachbarten Mauerscheiben ausgeschwemmt wird, ist kleiner. Werden solche L-förmigen Mauerscheiben in einem anderen als einem rechten Winkel aneinandergefügt, dann hat das die in der DE-PS 32 32 799 aufgezählten Nachteile: Die Ausrichtung der benachbarten Mauerscheiben ist sehr diffizil, weil für ein sauberes Erscheinungsbild eine linienförmige Berührung längs zweier Kanten benötigt wird, die stoß- und bruchgefährdet sind, und bei einer konvex verlaufenden Abfangmauer ergibt sich eine störende, keilförmige Fuge.In practice, however, there are often courses of intercepting walls in which straight sections meet at a certain angle. For straight sections, however, L-shaped concrete blocks are still preferred, in which the narrow side surfaces of the upright wall panels are flat and run at right angles to the front of the wall panel, because this gives the intercepting wall a more closed appearance and the risk that soil from the Back of the wall is washed out by the joint between two adjacent wall panels, is smaller. If such L-shaped wall panels are joined together at a angle other than a right angle, then this has the disadvantages listed in DE-PS 32 32 799: the alignment of the adjacent wall panels is very difficult because, for a clean appearance, a linear contact along two edges is needed, which are prone to impact and breakage, and with a convex retaining wall, a disruptive, wedge-shaped joint results.

Es wäre natürlich möglich, in einer Abfangmauer, die unterschiedlich gewinkelt verlaufen soll, im Bereich der Ecken Mauerscheiben vorzusehen, die gemäss der DE-PS 32 32 799 an beiden Seitenflächen gerundet sind, und im übrigen in den geradlinigen Abschnitten der Abfangmauer Mauerscheiben anzuordnen, die in an sich bekannter Weise ebene Seitenflächen haben. Das Zusammentreffen von ebenen Seitenflächen auf der einen und gerundeten Seitenflächen auf der anderen Seite hinterläßt jedoch einen unbefriedrigenden optischen Eindruck.It would of course be possible to provide wall washers in a corner wall, which should run at different angles, in the area of the corners, which are rounded on both side surfaces according to DE-PS 32 32 799, and otherwise to arrange wall disks in the straight sections of the wall have flat side surfaces in a manner known per se. The coincidence of flat side surfaces on one side and rounded side surfaces on the other leaves an unsatisfactory visual impression.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, für den Aufbau von abgewinkelten Abfangmauern L-förmige Betonsteine zur Verfügung zu stellen, mit denen sich die oben angeführten Nachteile vermeiden lassen.The present invention has for its object to provide L-shaped concrete blocks for the construction of angled retaining walls, with which the disadvantages mentioned above can be avoided.

Diese Aufgabe wird gelöst durch eine Eckenausbildung der Abfangmauer mit den im Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a corner formation of the interception wall with the features specified in claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Durch die Erfindung werden für den Aufbau von Abfangmauern aus L-förmigen Betonsteinen erstmals unsymmetrische L-förmige Betonsteine vorgeschlagen, deren aufrechte Mauerscheibe auf einer Seite eine gerundete Flanke und auf der gegenüberliegenden Seite eine ebene Flanke hat. Durch Anstoßen von zwei L-förmigen Betonsteinen, von denen einer auf der linken und der andere auf der rechten Seite gerundet ist, mit ihren gerundeten Flanken, kann man eine Ecke mit nahezu beliebigem Winkel bilden, die in jedem Fall hervorragend aussieht. Die in der Ecke liegende Stoßfuge hat eine optimale Gestalt, um z.B. von der Rückseite (Hangseite) her mit einer Dichtmasse abgedichtet zu werden. Durch die Rundung der Flanken sind dort die vorderen und hinteren lotrechten Kanten der Mauerscheibe verschwunden und können nicht mehr beschädigt werden. Zugleich ist die Notwendigkeit entfallen, die in der Ecke zusammenstoßenden Betonsteine millimetergenau zueinander auszurichten. Die Funktion und das Erscheinungsbild der Abfangmauern werden in der Ecke nicht gestört, wenn die Lage der Mantellinien, entlang derer zwei Mauerscheiben einander berühren, um einige Millimeter variiert.The invention proposes for the first time asymmetrical L-shaped concrete blocks for the construction of interception walls made of L-shaped concrete blocks, the upright wall disc of which has a rounded flank on one side and a flat flank on the opposite side. By bumping two L-shaped concrete blocks, one of which is rounded on the left and the other on the right, with their rounded flanks, you can form a corner with almost any angle that looks great in any case. The butt joint in the corner has an optimal shape, for example to be sealed with a sealing compound from the rear (slope side). Due to the rounding of the flanks, the front and rear vertical edges of the wall panel have disappeared and can no longer be damaged. At the same time, there is no need to align the concrete blocks colliding in the corner with millimeter precision. The function and appearance of the intercepting walls are not disturbed in the corner if the position of the surface lines is along of which two wall washers touch each other by a few millimeters.

Andererseits kann die Abfangmauer in dem an die Ecke anschließenden geradlinigen Bereich bis zur nächsten Ecke mit bekannten L-förmigen Betonsteinen fortgesetzt werden, die beidseits ebene Flanken haben, was zu einem geschlossenen Erscheinungsbild führt und das Ausschwemmen von Erdreich durch die Stoßfugen hindurch erschwert.On the other hand, the retaining wall can be continued in the rectilinear area adjoining the corner to the next corner with known L-shaped concrete blocks, which have flat flanks on both sides, which leads to a closed appearance and makes it more difficult to wash away soil through the butt joints.

Zur Ausbildung einer Aussenecke wird vorzugsweise die Fußscheibe eines der beiden die Ecke bildenden Betonsteine hochgesetzt, und zwar in einem solchen Abstand von der Unterseite der Mauerebene, welcher nur wenig mehr beträgt als die größte Dicke der Fußscheibe des anderen Betonsteins. Die beiden Betonsteine können dann nämlich mit einander überlappenden Fußscheiben aneinandergefügt werden. Es wäre allerdings auch möglich, doch nicht so günstig, für die Bildung von Aussenecken die Fußscheiben der beiden aneinander angrenzenden Betonsteine auf gleichem Niveau zu lassen; die Fußscheiben müssten dann verkleinert, insbesondere abgeschrägt sein.To form an outside corner, the base plate of one of the two concrete blocks forming the corner is preferably set up, at a distance from the underside of the wall plane which is only slightly more than the greatest thickness of the base plate of the other concrete block. The two concrete blocks can then be joined together with overlapping base plates. However, it would also be possible, but not so cheap, to leave the base plates of the two adjacent concrete blocks at the same level for the formation of outside corners; the foot disks would then have to be reduced in size, in particular beveled.

Bei der Bildung von Innenecken kommt eine Überlappung der beiden aneinander anstoßenden Betonsteine nicht in Betracht; hier können die Fußscheiben beider Betonsteine auf gleichem Niveau liegen und ebenso groß sein wie bei den bekannten L-förmigen Betonsteinen.When forming inside corners, an overlap of the two adjoining concrete blocks is out of the question; here the base plates of both concrete blocks can be at the same level and be as large as the known L-shaped concrete blocks.

Die Figuren 1 und 2 zeigen einen L-förmigen Betonstein 1 mit einer rechteckigen, waagerechten Fußplatte 2 und einer im rechten Winkel zu dieser angeordneten, sie beidseits überragenden Mauerscheibe 3, welche auf der linken Seite eine ebene Flanke 4 und auf der rechten Seite eine halbzylindrisch gerundete Flanke 5 hat.Figures 1 and 2 show an L-shaped concrete block 1 with a rectangular, horizontal base plate 2 and a wall plate 3 arranged at right angles to it and projecting on both sides, which has a flat flank 4 on the left side and a semi-cylindrical one on the right side has rounded flank 5.

Der in Figur 3 und 4 dargestellte Betonstein 6 ist dem in den Figuren 1 und 2 dargestellten Betonstein spiegelbildlich gleich, er hat seine halbzylindrisch gerundete Flanke 7 auf der linken Seite und die ebene Flanke 8 auf der rechten Seite.The concrete block 6 shown in FIGS. 3 and 4 is mirror-inverted the same as the concrete block shown in FIGS. 1 and 2, it has its semi-cylindrical flank 7 on the left side and the flat flank 8 on the right side.

Der in den Figuren 5 und 6 dargestellte Betonstein 9 unterscheidet sich von dem in den Figuren 3 und 4 dargestellten nur darin, dass seine Fußscheibe 10 hochgesetzt ist, und zwar um etwas mehr als die Dicke der Fußscheibe 2 des Betonsteins 6.The concrete block 9 shown in FIGS. 5 and 6 differs from that shown in FIGS. 3 and 4 only in that its base plate 10 is raised, namely by a little more than the thickness of the base plate 2 of the concrete block 6.

Die Figuren 7 und 8 zeigen eine aus den Betonsteinen 1 und 9 gebildete Aussenecke, in welcher diese beiden Betonsteine einen Winkel von 90° einschließen. Dabei überragt die hochgesetzte Fußscheibe 10 die untere Fußscheibe 2 um etwas mehr als deren Dicke. Die obere Fußscheibe kann sich deshalb - ggfs. nach Unterfütterung - auf der unteren Fußscheibe abstützen.FIGS. 7 and 8 show an outer corner formed from the concrete blocks 1 and 9, in which these two concrete blocks enclose an angle of 90 °. The raised base plate 10 projects over the lower base plate 2 by a little more than its thickness. The upper foot plate can therefore rest on the lower foot plate - if necessary after relining.

An die beiden die Ecke bildenden Betonsteine 1 und 9 können sich herkömmliche Betonsteine 11 anschließen, die ebene Flanken haben.Conventional concrete blocks 11, which have flat flanks, can be connected to the two concrete blocks 1 and 9 forming the corner.

Figur 9 zeigt in der Draufsicht eine Aussenecke, in welcher die beiden Betonsteine 1 und 9 einen von 90° verschiedenen Winkel miteinander einschließen. Für Aussenecken sind alle Winkel zwischen 0° und dem durch das Anschlagen der Fußplatten bestimmten Grenzwinkel (bei den gezeichneten Elementen etwas mehr als 90°) möglich.FIG. 9 shows a top view of an outside corner in which the two concrete blocks 1 and 9 enclose an angle other than 90 °. For outside corners, all angles between 0 ° and the critical angle determined by the striking of the foot plates (slightly more than 90 ° for the drawn elements) are possible.

Figur 10 zeigt die Bildung einer Innenecke, für welche praktisch jeder Winkel zwischen 0° und 180° möglich ist.Figure 10 shows the formation of an inner corner for which practically any angle between 0 ° and 180 ° is possible.
