Description

Die vorliegende Erfindung bezieht sich auf einen Bausatz, insbesondere für die Hangischerung und Flussbettverbauung und auf dessen Verwendung als Flussbettverbauung.The present invention relates to a kit, in particular for slope stabilization and river bed construction and to its use as a river bed construction.

Es sind eine Vielzahl von Hangsicherungselementen, Uferbefestigungen und als Böschungselemente verwendbare Verbundsteine bekannt. Es ist das Ziel der vorliegenden Erfindung, einen Bausatz anzugeben, der einerseits vielseitig verwendet werden kann und andererseits materialsparend und wirtschaftlich hergestellt werden kann. Dieses Ziel wird mit einem in den Ansprüchen beschriebenen Bausatz erreicht.A large number of slope stabilization elements, bank fortifications and composite stones which can be used as slope elements are known. It is the aim of the present invention to provide a kit which can be used in a variety of ways on the one hand and can be manufactured economically on the other hand. This goal is achieved with a kit described in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert werden. Es zeigen

  • Figur 1, in perspektivischer Sicht, ein Element,
  • Figur 2, in Ansicht, mehrere zusammengebaute Ele-.. mente,
  • Figur 3, in perspektivischer Sicht und in verkleinertem Masstab, eine Bachbettverbauung, und
  • Figur 4, in einer Sicht von vorne, zwei Elemente mit einer Verankerung.
The invention will be explained in more detail below with the aid of a drawing of an exemplary embodiment. Show it
  • FIG. 1, in perspective view, an element,
  • FIG. 2, in view, several assembled elements.
  • Figure 3, in perspective and on a reduced scale, a stream bed construction, and
  • Figure 4, in a view from the front, two elements with an anchor.

Man erkennt in Figur 1. ein polygonales, im wesentlichen sechs-eckiges Element 1, mit einer sechs-eckigen, durchgehenden Oeffnung 2 und Längsseiten 3 und 4, die an beiden Seiten je einen konischen Vorsprung 5 aufweisen. Die Breitseite 6 besteht aus zwei Seitenwänden 8 und einem parallel zu den Längsseiten verlaufenden Verankerungsteil 9. Die Verankerungsteile 9 weisen beidseitig einen konischen Vorsprung 10 auf, die gleich den Vorsprüngen 5 an den Längsseiten gerichtet sind. M an recognizes in Figure 1. a polygonal, essentially hexagonal element 1, with a hexagonal, continuous opening 2 and long sides 3 and 4, each having a conical projection 5 on both sides. The broad side 6 consists of two side walls 8 and an anchoring part 9 running parallel to the long sides. The anchoring parts 9 have a conical projection 10 on both sides, which are directed like the protrusions 5 on the long sides.

Wie aus der Figur ersichtlich, schliessen die beiden Seitenwände 8 der Breitseite einen stumpfen Winkel ein. Das Verankerungsteil 9 ist ferner mit einer Längsrinne 11 versehen, deren Bedeutung aus Figur 4 hervorgeht.As can be seen from the figure, the two side walls 8 form an obtuse angle on the broad side. The anchoring part 9 is also provided with a longitudinal channel 11, the meaning of which can be seen from FIG. 4.

In Figur 2 sind eine Anzahl zusammengebauter Elemente 1 dargestellt, wobei ersichtlich ist, dass jeweils ein Vorsprung 10 am Verankerungsteil 9 und ein Vorsprung 5 an der Längsseite 3 oder 4 hinter einem Vorsprung 5 an der Längsseite 3 oder 4 und hinter einen Vorsprung 10 an einem Verankerungsteil eines benachbarten Elementes greifen und dadurch eine Verankerung bewirken. Dabei ist ersichtlich, dass diese Konstruktion bewirkt, dass die Vorsprünge lediglich die Längskräfte aufnehmen müssen, während das Gewicht der Elemente sowie des in der Oeffnung sich befindlichen Erdreiches im wesentlichen von den Breitseiten aufgenommen wird. Falls ein ebener Abschluss gewünscht wird, kann ein trapezförmiges Abschlusselement 12 vorgesehen werden, das auf der kürzeren Längsseite zwei Vorsprünge 13 aufweist. Die Oeffnung des Elementes kann mit Erdreich gefüllt und bepflanzt werden.In Figure 2, a number of assembled elements 1 are shown, wherein it can be seen that in each case a projection 10 on the anchoring part 9 and a projection 5 on the long side 3 or 4 behind a projection 5 on the long side 3 or 4 and behind a projection 10 on one Grab anchoring part of an adjacent element and thereby effect an anchoring. It can be seen that this construction means that the projections only have to absorb the longitudinal forces, while the weight of the elements and of the soil located in the opening is essentially absorbed by the broad sides. If a flat end is desired, a trapezoidal end element 12 can be provided, which has two projections 13 on the shorter long side. The opening of the element can be filled with soil and planted.

Je nach Beschaffenheit des Geländes kann es notwendig werden, Elemente zu verankern, wobei dies auf die verschiedenste Weise geschehen kann. So können beispielsweise geeignet gebogene Verankerungen aus Armierungsstahl verwendet werden oder längs in den Rinnen 11 verlaufende Armierungsstäbe, die mittels Querstäben, die durch P-flökke oder dergleichen im Boden verankert werden, gehalten werden. Es können auch Erdanker gemäss Figur 4 verwendet werden, die aus einem Betonpfahl 14 mit rechteckigem Querschnitt bestehen und an ihren Enden je einen Eisenstab 15 und 16 aufweisen, der beidseitig auf eine gewisse Länge herausragt, wobei die Stäbe senkrecht aufeinander stehen. Der eine Stab 15 passt in die Rinne 11 des Verankerungsteils, während der andere Stab 16 eine zusätzliche Verankerung des Erdankers bewirkt. Anstelle des vorderen Stabes 15 kann der Pfahl eine konische Verdikkung aufweisen, wobei die Aussparung 22 am Verankerungsteil 9 entsprechend konisch ausgebildet sein muss.Depending on the nature of the terrain, it may be necessary to anchor elements, and this can be done in a variety of ways. For example, suitably curved reinforcements made of reinforcing steel can be used or longitudinal ones running in the channels 11 Reinforcing bars that are held by means of cross bars that are anchored in the floor by P-flökke or the like. It is also possible to use ground anchors according to FIG. 4, which consist of a concrete post 14 with a rectangular cross-section and each have an iron rod 15 and 16 at their ends, which protrudes on both sides to a certain length, the rods being perpendicular to one another. One rod 15 fits into the channel 11 of the anchoring part, while the other rod 16 effects additional anchoring of the ground anchor. Instead of the front rod 15, the pile can have a conical thickening, the recess 22 on the anchoring part 9 having to be correspondingly conical.

In Figur 3 ist die Verwendung von solchen Elementen bei der Flussbettverbauung dargestellt, wobei das Flussbett 17 mit der Böschung 18 im Schnitt dargestellt ist. Man erkennt darin die zusammengefügten Elemente 1 und am oberen Rand die Abschlusselemente 12. Quaderförmige Betonblöcke 19 dienen einerseits als Wellenbrecher und andererseits als zusätzliche Verankerung. Dabei ist es möglich, diese Betonblöcke länger zu machen und im Flussbett zu verankern. Um ein Ausspülen des Bodens zu verhindern, kann es zweckmässig sein, Böden 20 in die Oeffnungen der Grundelemente 1 zu stellen, wobei diese Böden entweder längslaufende Leisten 21 oder auch andere Griffe wie Vertiefungen oder Nocken aufweisen können, um deren Handhaben und Einsetzen zu erleichtern. Es ist in diesem Zusammenhange durchaus denkbar, diese Böden auch bei einer Hangsicherung zu verwenden, falls kein Erdreich oder nur eine sehr geringe Tiefe des Erdreichs gewünscht wird.-.FIG. 3 shows the use of such elements in the river bed construction, the river bed 17 with the embankment 18 being shown in section. The assembled elements 1 and the end elements 12 on the upper edge can be seen therein. Rectangular concrete blocks 19 serve on the one hand as a breakwater and on the other hand as additional anchoring. It is possible to make these concrete blocks longer and to anchor them in the river bed. In order to prevent the floor from being rinsed out, it may be expedient to place floors 20 in the openings of the basic elements 1, these floors either having longitudinal strips 21 or other handles such as depressions or cams in order to facilitate their handling and insertion. In this context, it is quite conceivable to use these floors also for slope stabilization if no soil or only a very small depth of the soil is desired.

Wie aus der vorhergehenden Beschreibung ersichtlich ist, sind die Elemente sowohl für eine Hangsicherung als auch für eine Flussverbauung brauchbar, es ist jedoch auch möglich, diese Elemente für den Bau von Trennwänden oder dergleichen, beispielsweise vor Einfamilienhäusern oder Reihenhäusern zu verwenden. Da das Gewicht im wesentlichen von den Breitseiten übertragen wird, ist ein Uebereinanderstellen gemäss dem Aufbau von Figur 2 mit diesen Elementen möglich.As can be seen from the preceding description, the elements can be used both for slope stabilization and for river lining, but it is also possible to use these elements for the construction of partition walls or the like, for example in front of single-family houses or R eihenhäusern to use. Since the weight is essentially transmitted from the broad sides, it is possible to stack these elements on top of one another in accordance with the structure of FIG.

Obwohl die wabenförmige, sechseckige Struktur der Elemente besonders vorteilhaft und ästhetisch besonders befriedigend ist, kann im Rahmen dieser Erfindung auch eine ander, im wesentlichen rechteckige Form verwendet werden, wobei die Oeffnung rechteckig und die Seitenwände der Breitseiten senkrecht auf die Längsseiten stehen. Es ist aber auch möglich, die Oeffnung 2 und die Aussenflächen abgerundet oder geschwungen zu gestalten.Although the honeycomb-shaped, hexagonal structure of the elements is particularly advantageous and aesthetically particularly satisfactory, another, essentially rectangular shape can also be used in the context of this invention, the opening being rectangular and the side walls of the broad sides being perpendicular to the long sides. But it is also possible to make the opening 2 and the outer surfaces rounded or curved.
