Abstract

In a retaining building block with an essentially frame-shaped type of construction for erecting plantable retaining structures, the front longitudinal wall (1) is designed roughly like a shield, the same projecting roughly by approximately the wall thickness at the top and in the longitudinal direction beyond the frame outlines. <IMAGE>

Description

Die Erfindung betrifft einen Böschungsbaustein, wobei die vordere Längswand etwa schildartig ausgebildet ist und oberseitig und in Längsrichtung über die Rahmenumrisse vorspringende Vorsprünge von etwa Wanddicke aufweist.The invention relates to an embankment block, the front longitudinal wall being approximately shield-like and having projections of approximately wall thickness projecting above and in the longitudinal direction over the frame outlines.

Es sind bereits Böschungsbausteine mit im wesentlichen rahmenartiger Bauart bekannt. So ist aus der US-PS 4 229123 ein etwa kastenartiger Stein bekannt, der aus einem Rahmen glatter scharfkantiger Wände besteht, wobei die beiden Querwände eine nach hinten fallende Stufe aufweisen, die als Ansatz für aufzusetzende Steine dient. Die Steine werden im gitterförmigen Verband aufgebaut und mit Boden verfüllt. Die hierbei entstehenden Lücken zwischen den Steinen geben eine Erdböschung frei und können bepflanzt werden.Slope blocks with an essentially frame-like design are already known. An approximately box-like stone is known from US Pat. No. 4,229,123, which consists of a frame of smooth, sharp-edged walls, the two transverse walls having a step falling backwards, which serves as an approach for stones to be placed on. The stones are built up in a lattice-like structure and filled with soil. The resulting gaps between the stones release an embankment and can be planted.

Beim bekannten System sind diese Lücken vorderseitig ganz offen, die Erdböschung wird nur durch die Vorderwand des Steines abgestützt. Die Pflanzen sind relativ ungeschützt Wind, Wetter und Sonneneinstrahlung ausgesetzt und scheuern bei Bewegung an den vorhandenen scharfen Kanten der Steine.In the known system, these gaps are completely open on the front, the embankment is only supported by the front wall of the stone. The plants are exposed to the wind, weather and sunlight relatively unprotected and rub against the sharp edges of the stones when moving.

Ein anderer Böschungsbaustein ist aus der DE-PS 25 37 408 bekannt. Dieser besitzt eine etwa schüsselbis trogartige Form mit Bodenplatte, aber ohne Rückwand.Another slope block is known from DE-PS 25 37 408. This has an approximately bowl-like shape with a base plate, but without a rear wall.

Aus der EP-A-0 047 718 ist ein Formhohlstein für die Verbauung von Uferböschungen bekannt, der eine schildförmige Stirnwand aufweist, die gegenüber den Seitenwänden einen Überrand und eine Überhöhe aufweist Dieser Formohlstein ist jedoch als Trog mit einer geschlossenen Bodenwand ausgebildet. Dies bedeutet, daß er damit aufgrund des höheren Gewichtes schwieriger in der Handhabung ist. Außerdem besitzen in den Trögen eingesetzte Pflanzen und Sträucher nur einen beschränkten Wurzelraum, wobei darüber hinaus die Gefahr besteht, daß diese leicht austrocknen, bzw. bei einem Standort mit einem hohen Wasseranfall bzw. in einer feuchten Umgebung oder einem regennassen Sommer verfaulen können.EP-A-0 047 718 discloses a shaped hollow block for the construction of bank embankments, which has a shield-shaped end wall which has an edge and an excess height with respect to the side walls. This shaped block is, however, designed as a trough with a closed bottom wall. This means that it is more difficult to handle due to its higher weight. In addition, plants and shrubs used in the troughs have only a limited root space, and there is also the risk that they can dry out easily or rot at a location with a high water intake or in a damp environment or a rainy summer.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Funktion solcher Steine zu verbesseren und insgesamt eine ästhetische Lösung in technisch-ökologischer Hinsicht zu finden wobei auch eine einfache und wirtschaftliche Herstellung gegeben sein soll.The present invention has for its object to improve the function of such stones and overall to find an aesthetic solution from a technical and ecological point of view, which should also be simple and economical to manufacture.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Baustein für die Errichtung bepflanzbarer Böschungsbauwerke im wesentlichen rahmenförmig ausgebildet ist, daß die Vorsprünge Rundungen an Ecken und Kanten aufweisen und daß die Rückwand und die beiden Querwände einen konischen Querschnitt aufweisen, der nach unten zu breiter ist.According to the invention, this object is achieved in that the building block for erecting embankment structures is essentially frame-shaped, that the projections have rounded corners and edges, and that the rear wall and the two transverse walls have a conical cross section which is too wide at the bottom.

Durch diese Ausgestaltung wird erreicht, daß die Erdböschungen in den Lücken einer Böschungswand vorteilhafterweise von den seitlichen Vorsprüngen der Vorderwand der erfindungsgemäßen Steine abgeschütztwerden, wodurch eine hohe Stabilität der Wand erreicht wird.This configuration ensures that the earth embankments in the gaps of an embankment wall are advantageously protected from the lateral projections of the front wall of the stones according to the invention, whereby a high stability of the wall is achieved.

Außerdem entstehen durch diese seitlichen Vorsprünge anstatt offener Lücken Nischen, die der Bepflanzung Schutz vor Wind, Wetter und zu intensiver Sonneneinstrahlung bieten.In addition, these side projections create niches instead of open gaps, which provide the planting with protection against wind, weather and excessive sunlight.

Dadurch, daß die Vorsprünge Rundungen an Ecken und Kanten aufweisen, wird eine Pflanzen-Freundlichkeit erreicht und es werden Verletzungen der Pflanzen infolge Scheuerns verhindert. Mit den erfindungsgemäßen Steinen wird auch ein ästhetisches Bild von Böschungsbauwerken erreicht.The fact that the projections have rounded corners and edges, a plant friendliness is achieved and injuries to the plants due to chafing are prevented. The stones according to the invention also achieve an aesthetic appearance of embankment structures.

Steine mit oberseitigen Vorsprüngen und Rundungen sind meist nur in zerlegbaren Handformen oder mittels Kippform-Maschinen herzustellen.Stones with protrusions and curves on the top side can usually only be produced in hand molds that can be dismantled or using tilting machines.

Die wirtschaftlichste Art der Herstellung solcher Steine erfolgt jedoch mit stationären Anlagen im Rüttel-Preß-Verfahren. Um die erfindungsgemäßen Steine in diesem Verfahren herstellen zu können, ist es erforderlich, das Problem der Volumenverteilung des Baustoffes im Formenkasten während der Verdichtung zu lösen. Dieses Problem kann erfindungsgemäß vorteilhaft gelöst werden. Bei Füllung des Formenkastens mit dem unverdichteten Baustoff, wie z.B. Beton od. dgl., liegen die Oberkanten des - unverdichteten - Steines in einer Ebene, nämlich in der Ebene der Formenkastenoberseite. Nun ist es aber erforderlich - unter Berücksichtigung gleichmäßiger Verdichtung - die Oberkanten der Querwände und der Rückwand etwa um Wandstärke gegenüber der Oberkante der Vorderwand abzusenken. Das wird erfindungsgemäß dadurch gelöst, daß die Rückwand und die beiden Querwände einen konischen Querschnitt aufweisen, der nach unten zu breiter ist und wobei ggf. die Konizität im unteren Bereich stärker ausgebildet ist.However, the most economical way of producing such stones is with stationary systems using the vibratory press method. In order to be able to produce the stones according to the invention in this process, it is necessary to solve the problem of the volume distribution of the building material in the mold box during the compaction. This problem can advantageously be solved according to the invention. When the mold box is filled with the uncompressed building material, e.g. Concrete or the like, the upper edges of the - undensified - stone lie in one plane, namely in the plane of the top of the mold box. Now it is necessary - taking into account uniform compression - to lower the upper edges of the transverse walls and the rear wall by approximately the wall thickness compared to the upper edge of the front wall. This is achieved according to the invention in that the rear wall and the two transverse walls have a conical cross-section which is too wide at the bottom and where the conicity in the lower region may be stronger.

Rückwand und Querwände sind damit im unteren Bereich voluminöser. Der Preßstempel kann beim Verdichtungsvorgang Baustoffvolumen nach unten drängen, bei Rückwand und Querwänden in höherem Maße, weil hier im unteren Bereich erfindungsgemäß mehr Volumen aufgenommen werden kann.The rear wall and transverse walls are therefore more voluminous in the lower area. The press ram can push down the volume of building material during the compression process, to a greater extent in the case of the rear wall and transverse walls, because according to the invention, more volume can be taken up in the lower region here.

Die konische Ausbildung der Rückwand und der Querwände, besonders im unteren Bereich an den Wandinnenseiten, bringt einen weiteren technischen Vorteil mit sich. Bei Böschungsbauwerken ist es wichtig, daß der abgestützte Boden an oder in den Böschungssteinen Halt vor Abrutschen findet. Diese Anforderung wird beim erfindungsgemäßen Stein nicht nur durch die Vorsprünge, sondern auch durch die Konizität der Rückwand und der Querwände im unteren Bereich der Innenseiten erzielt.The conical design of the rear wall and the transverse walls, especially in the lower area on the inside of the wall, has another technical advantage. In the case of embankment structures, it is important that the supported soil on or in the embankment stones has a hold against slipping. In the stone according to the invention, this requirement is achieved not only by the projections, but also by the conicity of the rear wall and the transverse walls in the lower region of the inner sides.

In Weiterbildung der Erfindung kann auch vorgesehen sein, daß die vordere Längswand einen etwa annähernd daumenförmigen Querschnitt mit konvexer Wölbung nach vorne (außen) und unterseitigem bartartigem Vorsprung nach hinten (innen) besitzt.In a further development of the invention it can also be provided that the front longitudinal wall has an approximately approximately thumb-shaped cross section with a convex shape xer curvature towards the front (outside) and beard-like projection on the underside towards the rear (inside).

Der bartartige Vorsprung auf der Innenseite der vorderen Längswand dient ebenfalls zur Abstützung des Verfüllbodens im Steininnem.The beard-like projection on the inside of the front longitudinal wall also serves to support the backfill floor inside the stone.

Eine ansprechende und gut zu handhabende Form ergibt sich, wenn in einer Ausgestaltung der Erfindung vorgesehen ist, daß die vordere Längswand - in der Draufsicht gesehen - eine vorderseitige flach verlaufende Ausbauchung aufweist, welche in die Rundungen der längsgerichteten Vorsprünge übergeht.An attractive and easy-to-use shape results if it is provided in one embodiment of the invention that the front longitudinal wall - seen in plan view - has a flat front bulge which merges into the curves of the longitudinal projections.

Für eine leichte Montage kann vorgesehen sein, daß die längsseitigen Vorsprünge in Abmessungen und Form, als Griffleiste ausgebildet sind.For easy assembly, it can be provided that the longitudinal projections are designed in terms of dimensions and shape as a grip strip.

Die Vorsprünge sind in Abmessungen und Form auf den menschlichen Handgriff abgestimmt und können somit optimal angefaßt und gehalten werden.The projections are matched in size and shape to the human handgrip and can thus be optimally handled and held.

Desweiteren können in Querwänden auf der Unterseite Ausnehmungen für Zinken von Montagegabeln od. dgl. vorgesehen sein, was ein vorteilhaftes Abnehmen der Steine von der Palette und ein wirtschaftliches Verbauen insbesondere bei großformatigen Steinen ermöglicht.Furthermore, recesses for tines of assembly forks or the like can be provided in the transverse walls on the underside, which enables the stones to be removed from the pallet in an advantageous manner and economically installed, particularly in the case of large-sized stones.

Im Hinblick auf erweiterte Bauweisen können die erfindungsgemäßen Böschungsbausteine auch an den Oberseiten der Querwände im Bereich der Ecken mit der Rückwand Schlitze aufweisen, welche das Einlegen von Ankerbändern od. dgl. vorteilhaft und kraftschlüssig ermöglichen. Dadurch können die erfindungsgemäßen Steine auch als Böschungsbauwerke nach dem Boden-Anker-Verbundprinzip verbaut werden.With regard to expanded designs, the slope blocks according to the invention can also have slots on the upper sides of the transverse walls in the region of the corners with the rear wall, which advantageously and force-fit enable the insertion of anchor bands or the like. As a result, the stones according to the invention can also be installed as embankments according to the soil-anchor composite principle.
