Abstract

1. Soil covering made of (concrete) shaped blocks which are laid at a distance from one another for the formation of vegetation growth, spacers being arranged in the longitudinal joints and transverse joints thus formed, characterized in that the spacers (17, 17a; 18; 19, 19a) consist of material which dissolves or decomposes in soil, in particular of wood, wooden material (chip material), waste paper, plastic or the like.

Description

Die Erfindung betrifft Erdreichabdeckungen aus (Beton-)Formsteinen, die zur Bildung von Bewuchs mit Abstand voneinander verlegt sind, wobei in so gebildeten Längsfugen und Querfugen Distanzstücke angeordnet sind.The invention relates to soil covers made of (concrete) shaped blocks which are laid at a distance from one another to form vegetation, spacers being arranged in the longitudinal joints and transverse joints formed in this way.

Für viele Erdreichabdeckungen aus Pflastersteinen oder (Beton-)Platten wird Rasenbewuchs gefordert. Bekannt sind Rasen-Pflastersteine, die Ausnehmungen aufweisen, um einen Rasenbewuchs zu ermöglichen.Lawn coverings are required for many paving stones or (concrete) slabs. Lawn paving stones are known which have recesses in order to enable lawn growth.

Es ist aber auch aereits bekannt, Pflastersteine bzw. Platten mit ausreichendem Abstand zueinander zu verlegen, so daß verhältnismäßig breite Fugen (Längsfugen und Querfugen) entstehen, in denen sich der Rasenbewuchs entwickeln kann. Um die Formsteine auf korrekten, vorbestimmten Abstand voneinander zu halten, sind auch bereits Distanzsteine aus Beton bekannt, die im Grundriß eine kreuz- oder T-förmige Gestalt aufweisen und im Bereich der Kreuzung von Längs- und Querfugen angeordnet werden. Die Distanzsteine haben eine geringere Konstruktionshöhe als die Pflastersteine bzw. Platten, so daß auch oberhalb der Distanzsteine Rasenbewuchs möglich ist.However, it is also known aereits to lay paving stones or slabs at a sufficient distance from one another so that relatively wide joints (longitudinal joints and transverse joints) are formed, in which the lawn can develop. In order to keep the shaped blocks at the correct, predetermined distance from one another, spacer blocks made of concrete are already known, which have a cruciform or T-shaped shape in the plan and are arranged in the region of the intersection of longitudinal and transverse joints. The spacer stones have a lower construction height than the paving stones or slabs, so that lawn growth is also possible above the spacer stones.

Die verhältnismäßig kleinen Distanzsteine aus Beton sind in der Herstellung kostenaufwendig. Des weiteren ist ungünstig, daß im Bereich der verlegten Distanzsteine die Entwicklung des Rasenbewuchses behindert ist, da eine Verbindung zum Untergrund durch die Distanzsteine verhindert wird.The relatively small spacer stones made of concrete are expensive to manufacture. Furthermore, it is unfavorable that the development of the lawn growth is hindered in the area of the laid spacer stones, since a connection to the ground is prevented by the spacer stones.

Der Erfindung liegt die Aufgabe zugrunde, eine Erdreichabdeckung aus Pflastersteinen bzw. (Beton-)Platten für Rasenbewuchs in entsprechend vorgesehenen Fugen vorzuschlagen, die kostengünstig hergestellt werden kann und den Rasenbewuchs nicht nennenswert beeinträchtigt.The invention has for its object to propose a soil cover made of paving stones or (concrete) slabs for lawn vegetation in appropriately provided joints, which can be produced inexpensively and does not significantly affect the lawn vegetation.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Erdreichabdeckung dadurch gekennzeichnet, daß die Distanzstücke aus sich im Erdreich auflösendem bzw. verrottendem Werkstoff bestehen, insbesondere aus Holz, Holzwerkstoff (Spanmaterial), Abfallpapier, Kunststoff od. dgl.To achieve this object, the soil cover according to the invention is characterized in that the spacers consist of material that dissolves or rots in the soil, in particular wood, wood-based material (chip material), waste paper, plastic or the like.

Der Einsatz von Distanzstücken aus einem im Erdreich sich nach und nach auflösendem Werkstoff hat den überraschenden Effekt, daß zunächst eine exakte Positionierung der Formsteine unter Bildung von Fugen vorgegebener Größe und Form ermöglicht wird, nach einer gewissen Zeit aber die gebildeten Fugen für den Bewuchs (Rasen) frei zur Verfügung stehen. Es fehlen die bei den herkömmlichen Distanzstücken aus Beton üblichen Lücken im Bewuchs.The use of spacers made of a material that gradually dissolves in the soil has the surprising effect that first of all an exact positioning of the shaped stones is made possible with the formation of joints of a given size and shape, but after a certain time the joints formed for the vegetation (lawn ) are freely available. The gaps in the vegetation that are common with conventional spacers made of concrete are missing.

Die Distanzstücke können ertindungsemäß in verschiedener weise ausgebildet sein. Aus wirtschaftlicher Sicht besonders vorteilhaft sind platten- bzw. stabförmige Distanzstücke aus gepreßten Holzwerkstoffen (Span- bzw. Fasermaterial). Diese Distanzstücke sind besonders kostengünstig herstellbar, da das Material häufig als Abfall in der Holzindustrie anfällt und leicht zu stabförmigen Enden zugeschnitten werden kann.The spacers can be designed in various ways according to the invention. From an economic point of view, plate or rod-shaped spacers made of pressed wood materials (chip or fiber material) are particularly advantageous. These spacers can be produced particularly inexpensively, since the material often arises as waste in the wood industry and can easily be cut into rod-shaped ends.

Zur Verbesserung des Bewuchses unmittelbar nach der Verlegung der Erdreichabdeckung können die Distanzstücke mit aufrechten Öffnungen, Bohrungen od. dgl. versehen sein.To improve the vegetation immediately after laying the soil cover, the spacers can be provided with upright openings, bores or the like.

Die erfindungsgemäße Ausführung der Distanzstücke ermöglicht weitere wichtige Maßnahmen, nämlich die Kombination derselben mit den Bewuchs ermöglichenden bzw. fördernden Substanzen. So können die Distanzstücke mit (flüssigen) Nährstoffen, Düngemitteln und anderen Bodenverbesserungsmitteln getränkt sein. Diese Substanzen gehen bei der Auflösung der Distanzstücke in den Boden über und unterstützen den Bewuchs innerhalb der Fugen. Die vorgenannten Mittel können auch als feste (gepreßte) Portionen innerhalb von Ausnehmungen der Distanzstücke angebracht sein. Gleiches gilt für die Anordnung von Rasensamen.The design of the spacers according to the invention enables further important measures, namely the combination of the same with the substances which enable or promote the growth. The spacers can be saturated with (liquid) nutrients, fertilizers and other soil improvers. These substances pass into the soil when the spacers dissolve and support the growth within the joints. The aforementioned means can also be attached as fixed (pressed) portions within recesses in the spacers. The same applies to the arrangement of lawn seeds.

Weitere Merkmale der Erfindung betreffen die Ausgestaltung der Distanzstücke und die Anordnung derselben innerhalb der Erdreichabdeckung.Further features of the invention relate to the design of the spacers and the arrangement of the same within the ground cover.

Exemplary embodiments of the invention are explained in more detail below with reference to the drawings. It shows:
  • 1 shows a section of a soil cover (paving slab) with spacers in joints,
  • 2 shows a larger section of a pavement with another embodiment of the spacers,
  • 3 shows a cross section through an earth cover with spacers,

In den Zeichnungen ist eine Erdreichabdeckung aus rechteckigen, plattenförmigen Formsteinen 10 aus Beton gezeigt. Diese können eine Höhe bzw. Dicke von 10 oder 12 cm haben.In the drawings, a soil cover is shown made of rectangular plate-shaped molded bricks 1 0 concrete. These can have a height or thickness of 10 or 12 cm.

Die Formsteine werden auf einem vorbereiteten Untergrund verlegt, nämlich auf einem auf planiertem Boden 11 hergestellten Pflasterbett 12 aus Sand, Kies od. dgl.The shaped blocks are laid on a prepared surface, namely on a plaster bed 12 made of sand, gravel or the like, which is produced on leveled floor 11.

Auf dem Pflasterbett 12 können die Formsteine 1o in geeigneter Weise verlegt werden. Bei den Ausführungsbeispielen der Fig. 1 und 2 sind die Formsteine 1o in (quergerichteten) Reihen 13 angeordnet. Zwischen diesen entstehen durchgehende Fugen, nämlich Querfugen 14. Die Formsteine 1o innerhalb einer Reihe 13 sind gegenüber denjenigen der benachbarten Reihen mittig versetzt angeordnet (Verband). Dadurch entstehen innerhalb der Reihen zwischen benachbarten Formsteinen 1o kurze Stoßfugen, nämlich Längsfugen 15.The shaped blocks 10 can be laid in a suitable manner on the paving bed 12. In the exemplary embodiments of FIGS. 1 and 2, the shaped blocks 10 are arranged in (transverse) rows 13. Continuous joints, namely transverse joints 14, are formed between them. The shaped blocks 10 within a row 13 are offset in relation to those of the adjacent rows (bond). This results in short butt joints, namely longitudinal joints 15, within the rows between adjacent shaped blocks 10.

Die Fugen (Querfugen 14, Längsfugen 15) sollen verhältnismäßig breit ausgebildet sein (etwa 4-5 cm), so daß innerhalb der Fugen 14, 15 (Rasen-)Bewuchs 16 sich ausbilden kann (Fig. 4).The joints (transverse joints 14, longitudinal joints 15) should be relatively wide (about 4-5 cm) so that within the joints 14, 15 (lawn) vegetation 16 can form (FIG. 4).

Um möglichst exakte Fugen 14, 15 zu bilden, sind in diesen Distanzstücke 17, 17a, 18, 19 bzw. 19a angeordnet. Diese bestehen nicht aus Beton, sondern aus einem kostengünstigen Material, vorzugsweise Abfallmaterial, welches zudem die Eigenschaft aufweisen soll, nach gewisser Zeit im Boden zu vergehen. Dabei wird berücksichtigt, daß nach der Verlegung der Formsteine 1o und nach Konsolidierung der Erdreichabdeckung die Distanzstücke funktionell nicht mehr erforderlich sind. Für den Bewuchs ist es sogar günstig, wenn die Distanzstücke nach und nach verschwinden, so daß der Bewuchs sich durchgehend und ungehindert ausbreiten kann. Vorzugsweise bestehen die Distanzstücke 17 .. 19 aus Holz bzw. Holzwerkstoff. Andere Materialien, wie Abfall-Papier mit Bindemitteln, Kunststoff od. dgl. sind ebenfalls geeignet.In order to form joints 14, 15 which are as precise as possible, spacers 17, 17a, 18, 19 and 19a are arranged in these. These are not made of concrete, but of an inexpensive material, preferably waste material, which is also said to have the property of verge in the ground after a certain time hen. It is taken into account that after the laying of the stones 10 and after consolidation of the soil cover, the spacers are no longer functionally required. It is even beneficial for the vegetation if the spacers gradually disappear, so that the vegetation can spread continuously and unhindered. The spacers 17 .. 19 are preferably made of wood or wood-based material. Other materials such as waste paper with binders, plastic or the like are also suitable.

Eine vorteilhafte Ausführungsform der Distanzstücke 17, 17a ist in Fig. 1, 3 und 4 gezeigt. Ein langgestreckter, im Querschnitt quadratischer oder rechteckiger Stab aus Holz bzw. Holzwerkstoff (Spanmaterial) ist mit möglichst großen Bohrungen 2o versehen, die über die volle Höhe der Distanzstücke 17, 17a durchgehen. Von diesem Stab sind kurze Abschnitte abgetrennt, die die Distanzstücke 17, 17a bilden. Bei dem Beispiel der Fig. 1 sind im Bereich von kurzen Fugen (Längsfugen 15) kurze Distanzstücke 17a mittig in bezug auf die Formsteine 1o angeordnet. Das Distanzstück ist durch Abtrennen mittig im Bereich einer Bohrung gebildet, so daß an den Enden offene, halbkreisförmige Vertiefungen 21 entstehen. Unter Berücksichtigung der Ma- ;erialfestigkeit und der Belastung sind die Bohrungen 2o und die Länge der Distanzstücke 17, 17a so bemessen, daß möglichst wenig Material bleibt, um den Bewuchs 16 nicht zu beeinträchtigen.An advantageous embodiment of the spacers 17, 17a is shown in FIGS. 1, 3 and 4. An elongated, cross-sectionally square or rectangular rod made of wood or wood-based material (chip material) is provided with the largest possible bores 2o which go through the full height of the spacers 17, 17a. Short sections which form the spacers 17, 17a are separated from this rod. In the example of FIG. 1, short spacers 17a are arranged centrally in the region of short joints (longitudinal joints 15) with respect to the shaped blocks 10. The spacer is formed by separating in the center in the region of a bore, so that open, semicircular depressions 21 are formed at the ends. Taking into account the strength of the material and the load, the bores 2o and the length of the spacers 17, 17a are dimensioned such that as little material as possible remains in order not to impair the growth 16.

Im Bereich durchgehender Fugen (Querfugen 14) sind Distanzstücke 17 angeordnet, die um eine Bohrung 2o länger sind. Die Distanzstücke 17 sind hier mittig zur Längsfuge 15 gelegt, so daß drei Formsteine 1 auf dem gemeinsamen Distanzstück abgestützt sind.In the area of continuous joints (transverse joints 14) spacers 17 are arranged, which are longer by a hole 2o. The spacers 17 are placed centrally to the longitudinal joint 15, so that three shaped blocks 1 are supported on the common spacer.

Bei dem Ausführungsbeispiel der Fig. 2 sind in den durchgehenden Fugen (Querfugen 14) langgestreckte, lattenförmige Distanzstücke 18 angeordnet mit dicht bei dicht liegenden Bohrungen 20. Hier ist demnach eine Abstützung der Formsteine 1o auf voller Länge im Bereich der Querfugen 14 gewährleistet. Die Längsfugen 15 weisen wiederum kurze Distanzstücke 17 auf.In the exemplary embodiment in FIG. 2, elongated, lath-shaped spacers 18 are arranged in the continuous joints (transverse joints 14) with bores 2 0 lying close to one another. Here, a full length support of the shaped blocks 10 is guaranteed in the area of the transverse joints 14. The longitudinal joints 15 in turn have short spacers 17.

Die Distanzstücke 17 .. 19 haben eine deutlich geringere Konstruktionshöhe als die Formsteine 10, nämlich etwa die halbe Höhe. Die Distanzstücke 17 .. 19 werden ebenfalls auf dem Pflasterbett 12 verlegt. Der darüber und dazwischen entstehende freie Raum wird mit Mutterboden 22 ausgefüllt, so daß hier der Bewuchs 16 entstehen kann.The spacers 17 .. 19 have a significantly lower construction height than the shaped blocks 1 0 , namely approximately half the height. The spacers 17 .. 19 are also laid on the plaster bed 12. The free space created above and in between is filled with topsoil 22 so that vegetation 16 can arise here.

Eine weitere Gestaltungsmöglichkeit für Distanzstücke 19, 19a ist in Fig. 5 und 6 gezeigt. Hier sind kleinere Distanzstücke (19) und größere Distanzstücke (19a) gezeigt mit an beiden Längsseiten offenen, halbkreisförmigen Ausnehmungen 23. Auch diese Distanzstücke gewährleisten eine ausreichende Abstützung der Formsteine 1 gegeneinander bei geringer Grundfläche als (anfängliches) Hindernis für den Bewuchs. Des weiteren können auch diese Distanzstücke 19, 19a aus platten- bzw. stabförmigen Zwischenprodukten aus Holz bzw. Holzwerkstoff mit Bohrungen hergestellt werden.Another design option for spacers 19, 19a is shown in FIGS. 5 and 6. Smaller spacers (19) and larger spacers (19a) are shown here with semicircular recesses 23 open on both long sides. These spacers also ensure sufficient support of the shaped blocks 1 against one another with a small base area as an (initial) obstacle to the growth. Furthermore, these spacers 19, 19a can also be produced from plate-shaped or rod-shaped intermediate products made of wood or wood-based material with bores.

Die Distanzstücke können vielfach modifiziert werden. So kann es vorteilhaft sein, die Bohrungen bzw. Öffnungen konisch auszubilden mit nach oben sich erweiterndem Querschnitt. Alternativ können auch rechteckige oder quadratische durchgehende Ausnehmungen in den Distanzstücken angeordnet sein. Insgesamt ist ein querbelastbares Gittertragwerk angebracht, das möglichst großflächige Öffnungen bzw. Durchgänge für den Bewuchs freigibt.The spacers can be modified in many ways. It may be advantageous to make the bores or openings conical with a cross section widening upwards. Alternatively, rectangular or square continuous recesses can also be arranged in the spacers. Overall, a cross-loadable lattice structure is attached, which opens the largest possible openings or passages for the vegetation.

Bei der Auswahl geeigneter Werkstoffe können diese mit eingearbeiteten Düngemitteln und/oder Rasensamen versehen sein. Bei Verwendung flüssiger Bodenverbesserungsmittel können die Distanzstücke aus geeignetem (porösem) Werkstoff mit diesem Bodenverbesserungsmittel getränkt sein. Des weiteren können in den Bohrungen bzw. Öffnungen vorgeformte Rasenstücke bzw. Elemente aus Düngemittel mit Rasensamen eingesetzt sein, so daß komplette, den Bewuchs unterstützende Distanzstücke eingesetzt werden.When selecting suitable materials, these can be provided with incorporated fertilizers and / or lawn seeds. When using liquid soil improvers, the spacers made of a suitable (porous) material can be impregnated with this soil improver. Furthermore, pre-formed lawn pieces or elements made of fertilizer with lawn seeds can be inserted into the bores or openings, so that complete spacers supporting the vegetation are used.

Die dargestellten und beschriebenen Distanzstücke gewährleisten eine sichere Positionierung der Formsteine gegeneinander. Unter dem Bewuchs befinden sich keine, die Entwicklung desselben behindernden Beton-Elemente. Vielmehr wird durch die Ausbildung der Distanzstücke eine praktisch durchgehende Wurzelbildung gewährleistet. Holz und ähnliche Werkstoffe haben darüber hinaus den Vorteil, daß die Distanzstücke Wasser speichern und sich bei Wärmeeinstrahlung nicht aufheizen. Auf einfache, kostengünstige Weise ist eine Anpassung an Steingrößen sowie an die Breite der gewünschten Fugen möglich. Das vermodernde Holz dient als zusätzliche Wurzelnahrung für den Bewuchs.The spacers shown and described ensure a secure positioning of the stones against each other. Under the vegetation there are no concrete elements that hinder the development of the same. Rather, the formation of the spacers ensures practically continuous root formation. Wood and similar materials also have the advantage that the spacers store water and do not heat up when exposed to heat. In a simple, inexpensive way, adaptation to stone sizes and the width of the desired joints is possible. The decaying wood serves as additional root food for the vegetation.
