Description

Die vorliegende Erfindung betrifft einen Formhohlstein für die Verbauung von Uferböschungen gemäss dem Gattungsbegriff des unabhängigen Patentanspruchs 1.The present invention relates to a hollow block for the construction of embankments according to the preamble of independent claim 1.

Aus der CH-A 587'390 sind Böschungssteine aus Beton bekannt geworden, die sich zur Befestigung von Böschungen eignen. Diese Böschungssteine bestehen aus einer eine Stirnwand und zwei Seitenwände miteinander verbindenden Bodenplatte. Diese Bodenplatte weist auf ihrer Unterseite zwei rinnenförmige, parallel zu den Seitenwänden verlaufende Vertiefungen auf, die sich durch die Stirnwand fortsetzen. Bei der Schichtung werden die Vertiefungen über die Seitenwände der unteren Reihe gelegt, so dass sich eine Verzahnung ergibt. Während sich derartige Böschungssteine sehr gut für trockene Verlegung von Stützmauern od.dgl. eignen, können sie zur Verbauung von Uferböschungen im Bereich des Wasserstandes weniger gut gebraucht werden, weil sie nirgends einen Abschluss gegen das gewachsene oder aufgeschüttete Erdreich bilden können.From CH-A 587'390, embankment stones made of concrete have become known which are suitable for fastening embankments. These embankment stones consist of a base plate connecting one end wall and two side walls. This bottom plate has on its underside two channel-shaped depressions that run parallel to the side walls and continue through the end wall. When layering, the depressions are placed over the side walls of the lower row, so that there is a toothing. While such embankment stones are very good for dry laying of retaining walls or the like. suitable, they can be used less well to block bank embankments in the area of the water level, because they can never form a seal against the grown or heaped up soil.

Es wurden dann auch Versuche mit verdicktem Boden zur Erhöhung des Gewichts, ohne Vertiefungen im Boden zur Bildung von abdichtenden Riegeln zwischen Seitenwänden und Boden, ferner mit einer Querwand parallel zur Stirnwand und mit flügelartigen Seitenriegeln aussenseitig an den Seitenwänden durchgeführt. Im Vergleich zu einer herkömmlichen Verbauung mit Naturbruchsteinen sind natürlich derartige Böschungssteine wesentlich teurer; sie lassen sich aber auf einfache Weise von der Wasserlinie an begrünen und unter der Wasserlinie können die Vertiefungen mit Bollensteinen gefüllt werden, um so das Gewicht der Böschungssteine zu erhöhen. Es hat sich jedoch gezeigt, dass alle diese genannten Massnahmen zusammen nicht genügen, um einem Wasserlauf mit gekrümmten und geraden Stellen das natürliche Aussehen zu geben, weil bei einer Aneinanderreihung unter einem Winkel kein genügender Abschluss gegen das Erdreich gewährleistet ist und deshalb eine Gefahr für das Ausschwemmen besteht.Experiments were then also carried out with a thickened bottom to increase the weight, without depressions in the bottom to form sealing bars between the side walls and bottom, further with a transverse wall parallel to the end wall and with wing-like side bars on the outside of the side walls. In comparison to a conventional installation with natural quarry stones, such embankment stones are of course much more expensive; however, they can be greened easily from the waterline and below the waterline, the depressions can be filled with bulging stones to increase the weight of the embankment stones. It has been shown, however, that all of these measures together are not sufficient to give the natural appearance of a watercourse with curved and straight sections, because if they are lined up at an angle, a sufficient seal against the ground is not guaranteed and therefore a danger to the Flooding out exists.

Es ist deshalb Aufgabe der Erfindung, einen Formhohlstein zu schaffen, mit dem alle Belange bei Uferverbauungen erfüllt werden können.It is therefore an object of the invention to provide a shaped hollow block with which all concerns relating to bank structures can be met.

Erfindungsgemäss wird dies durch die Merkmale im kennzeichnenden Teil des unabhängigen Patentanspruchs 1 erreicht. Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung erläutert. Es zeigen:

  • Fig. 1 eine perspektivische Ansicht eines Formhohlsteins nach der Erfindung in einer ersten Ausführungsform,
  • Fig. 2 eine perspektivische Ansicht eines Formhohlsteins nach der Erfindung in einer zweiten Ausführungsform,
  • Fig. 3 bis Fig. 5 einen Aufriss, Grundriss und einen Querschnitt einer mit Formhohlsteinen nach der Erfindung bewehrten Uferböschung.
According to the invention this is achieved by the features in the characterizing part of independent claim 1. Embodiments of the invention are explained below with reference to the drawing. Show it:
  • 1 is a perspective view of a molded hollow block according to the invention in a first embodiment,
  • 2 is a perspective view of a molded hollow block according to the invention in a second embodiment,
  • Fig. 3 to Fig. 5 shows an elevation, floor plan and a cross section of a bank embankment reinforced with hollow form stones according to the invention.

Die beiden Ausführungsformen des Formhohlsteins nach der Erfindung gemäss Fig. 1 und 2 zeigen je eine Stirnwand 10 und daran anschliessend eine Bodenwand 11 und zwei Seitenwände 12, 13. Die Stirnwand 10 ist schildförmig als halbkreisförmige Platte ausgebildet, die gegenüber der Aussenfläche der Seitenwände 12, 13 einen Ueberrand 15 und gegenüber den Oberkanten der genannten Seitenwände 12, 13 eine Ueberhöhe 20 aufweist.1 and 2 each show an end wall 10 and then a bottom wall 11 and two side walls 12, 13. The end wall 10 is designed in the shape of a shield as a semicircular plate, which is opposite the outer surface of the side walls 12, 13 has an upper edge 15 and an excess height 20 with respect to the upper edges of said side walls 12, 13.

Der durch die Seitenwände 12, 13 und die Bodenwand 11 gebildete Trog 16 ist durch eine Querwand 17 (Fig. 1) in zwei etwa gleiche Teile unterteilt. Auf der Aussenseite tragen die Seitenwände im Bereich der Querwand 17 zwei Stützwände 18, 19, die gegeneinander versetzt angeordnet sind, derart, dass sie sich beim Aneinanderreihen von Formhohlsteinen gegenseitig hintergreifen.The trough 16 formed by the side walls 12, 13 and the bottom wall 11 is divided into two approximately equal parts by a transverse wall 17 (FIG. 1). On the outside they wear Side walls in the region of the transverse wall 17 two supporting walls 18, 19 which are arranged offset with respect to one another such that they engage behind one another when mold hollow blocks are lined up.

Der Ueberrand 15 der Stirnfläche 10 ist kleiner als die seitliche Ausdehnung der Stützwände 18, 19.The upper edge 15 of the end face 10 is smaller than the lateral extent of the support walls 18, 19.

Der Zweck dieser Ueberränder 15 und Stützwände 18, 19 ist leicht einzusehen. Wenn die Formhohlsteine mit seitlich aneinander anstossenden Stirnwänden verlegt werden, bilden sich bei der nach hinten verlaufenden Böschung einerseits durch die Tröge 16 und anderseits durch die Seitenwände und die sich hintergreifenden Stützwände 18, 19 Kammern, in denen das Wasser aufgefangen wird und das Erdreich hinter den Formhohlsteinen nicht ausschwemmen kann. Bei konkaven Krümmungen bleiben die Stirnwände aneinander angrenzend und die Stützwände können auseinandergezogen werden, bis sie sich gerade noch berühren. Anderseits können bei konvexer Krümmung die Stirnwände auseinandergezogen werden und die Stützwände bleiben miteinander im Eingriff.The purpose of these overhangs 15 and retaining walls 18, 19 is easy to see. If the hollow form stones are laid with laterally abutting end walls, the backward slope is formed on the one hand by the troughs 16 and on the other hand by the side walls and the rear-engaging supporting walls 18, 19 chambers in which the water is collected and the soil behind the Cannot wash out hollow form stones. In the case of concave curvatures, the end walls remain adjacent to one another and the support walls can be pulled apart until they just touch. On the other hand, with a convex curvature, the end walls can be pulled apart and the support walls remain in engagement with one another.

Ueberdies ermöglichen die Ueberränder zusammen mit den Stützwänden 18, 19 auch eine aufgelockerte Verlegung der Steine und damit eine Verbilligung der Uferbefestigung.In addition, the overhangs, together with the support walls 18, 19, also allow the stones to be laid loosely and thus make the bank fastening cheaper.

Fig. 3 - 5 zeigen eine Schichtungsart von Formhohlsteinen in aufgelockerter Verlegung im Aufriss, Grundriss und im Querschnitt.3 - 5 show a layering of hollow form stones in loosened laying in elevation, floor plan and in cross section.

Gemäss dem zweiten Ausführungsbeispiel nach Fig. 2 ist die Querwand 21 nicht einstückig mit den Seitenwänden und der Bodenwand ausgebildet, sondern als separates Teil gefertigt, zu dessen Halterung die Seitenwände 12, 13 auf ihrer Innenseite je einen Wulst 22, 23 mit einer senkrecht auf der Bodenwand stehenden Nut 24, 25 aufweisen. Der Vorteil einer solchen Ausführungsform kann darin gesehen werden, dass über dem Normalwasserpegel die Formhohlsteine vollständig mit Erde gefüllt und dann bepflanzt werden können, wobei sich innert kurzer Zeit eine biologische Verbindung mit dem gewachsenen Boden bildet und sich bei Hochwasser trotzdem keine Ausschwemmungen des Erdreichs ergeben können, weil der Schutz vor reissendem Wasser durch die Ueberränder und die Ueberhöhe einerseits und die Stützwände andererseits bestehen bleibt.According to the second embodiment of FIG. 2, the transverse wall 21 is not formed in one piece with the side walls and the bottom wall, but is made as a separate part, for holding the side walls 12, 13 on the inside of each a bead 22, 23 with a perpendicular to the Have bottom wall standing groove 24, 25. The advantage of such an embodiment can be seen in the fact that above the normal water level, the hollow form stones can be completely filled with soil and then planted, whereby a biological connection with the grown soil is formed within a short time and no flooding of the soil can nevertheless occur in the event of flooding , because the protection against tearing water by the overhangs and the excess height on the one hand and the retaining walls on the other hand remains in place.

Beide Ausführungsformen des vorgeschlagenen Formhohlsteins eignen sich selbstredend auch für normale Stützmauern, insbesondere bei lockerem Erdreich oder bei stark feuchtem Untergrund kann der lange Trogteil mit den Stützwänden für eine Schwergewichtsmauer Verwendung finden.Both embodiments of the proposed hollow form are of course also suitable for normal retaining walls, in particular in the case of loose soil or in the case of very damp underground, the long trough part with the retaining walls can be used for a heavyweight wall.
