Abstract

In order to maintain a predetermined distance between paving blocks (2) and thus to make it possible for the joints (6) to be provided with greenery, spacing elements (1) consisting of concrete or wood have hitherto been used. However, these present serious disadvantages. Concrete spacing elements are too heavy and spacing elements consisting of rottable material, for example wood, do not ensure that the paving blocks (2) remain fixed once they have rotted. To overcome these disadvantages, the new spacing element (1) consists of a T- shaped hollow profile which is made of plastic and is open at both ends. <IMAGE>

Description

Es ist heutzutage vielfach üblich, private und öffentliche Geh- und Fahrwege mit auf gegenseitigen Abstand verlegten Pflastersteinen zu befestigen, wobei die Fugen zwischen den Pflastersteinen begrünt werden.Nowadays it is common practice to fasten private and public walkways and driveways with paving stones laid at a distance from one another, with the joints between the paving stones being planted.

Um einen vorgegebenen Abstand zwischen den Pflastersteinen einzuhalten, werden Abstandhalter aus Beton oder Holz verwendet, die jedoch schwerwiegende Nachteile haben.Spacers made of concrete or wood are used to maintain a predetermined distance between the paving stones, but these have serious disadvantages.

Aus Beton bestehende Abstandhalter sind zu schwer, so daß durch mühsames Mitschleppen dieser Abstandhalter aus Beton die Verlegearbeit erschwert wird. Außerdem behindern sie zu stark die Wurzelbildung der Grünbepflanzung der Fugen.Spacers made of concrete are too heavy, so that laborious dragging of these spacers made of concrete makes the laying work more difficult. They also hinder the formation of roots in the greenery of the joints.

Aus Holz bestehende Abstandhalter vermodern mit der Zeit, was zwar beabsichtigt ist, wodurch aber die Festlegung der Pflastersteine dann nicht mehr gewährleistet ist, da die selbst zu Erde gewordenen Abstandhalter keinen seitlichen festen Halt mehr für die Pflastersteine bieten.Spacers made of wood will deteriorate over time, which is intended, but as a result the fixing of the paving stones is no longer guaranteed, since the spacers which have themselves become earth no longer offer any firm lateral support for the paving stones.

Ein gemeinsamer Nachteil beider Arten von Abstandhaltern besteht schließlich darin, daß sie beim Festrütteln den Pflastersteinen die Möglichkeit geben, sich zu verschieben und zu kippen.Finally, a common disadvantage of both types of spacers is that they give the paving stones the opportunity to shift and tilt when firmly shaken.

Der Erfindung liegt die Aufgabe zugrunde, einen Abstandhalter für Pflastersteine zu schaffen, der ein äußerst geringes Gewicht hat, statisch stabil ist und bei genauer Festlegung der Fugenbreiten das Verlegen von Pflastersteinen wesentlich erleichtert.The invention has for its object to provide a spacer for paving stones, which has an extremely low weight, is statically stable and the laying of paving stones much easier with precise determination of the joint widths.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Abstandhalter in Form eines in Verlegestellung oben und unten offenen T-förmigen Hohlprofils aus Kunststoff mit drei Hohlkammern, von denen die mittlere Hohlkammer größer als die beiden äußeren Hohlkammern ist und den Steg des T-förmigen Hohlprofils bildet und von denen die äußeren Hohlkammern die beiden Flansche des T-förmigen Hohlprofils bilden.This object is achieved according to the invention by a spacer in the form of a T-shaped hollow profile made of plastic with three hollow chambers open at the top and bottom in the installation position, of which the middle hollow chamber is larger than the two outer hollow chambers and forms the web of the T-shaped hollow profile and from which the outer hollow chambers form the two flanges of the T-shaped hollow profile.

Zweckmäßig ist die mittlere Hohlkammer nur im Bereich der in Verlegestellung oberen Hälfte durch Verbindungsstege von den äußeren Hohlkammern getrennt.The middle hollow chamber is expediently separated from the outer hollow chambers only by connecting webs in the area of the upper half in the installed position.

Erfindungsgemäße Abstandhalter sind wegen ihres geringen Gewichtes in großen Mengen (bis zu 400 Stück) leicht von Hand transportierbar. Es ist möglich, beispielsweise auf einem 25-t-LKW, der mit palettierten Pflastersteinen für beispielsweise 130 bis 135 m² beladen ist, auch noch die dafür benötigte Anzahl von Abstandhaltern auf dem LKW unterzubringen, da notwendigerweise zwischen den Steinpaketen ohnehin noch genügend Laderaum frei ist. Durch die Formgebung (T-Profil) wird die Verlegearbeit wesentlich vereinfacht und erleichtert. Ferner geben die erfindungsgemäßen Abstandhalter dem Pflanzgut optimalen Platz zur Wurzelbildung und verhindern auch beim Festrütteln ein Verschieben der Pflastersteine.Spacers according to the invention can be easily transported by hand in large quantities (up to 400 pieces) because of their low weight. It is possible, for example, to accommodate the number of spacers required for this on the truck, for example on a 25 t truck loaded with palletized paving stones for, for example, 130 to 135 m², since there is necessarily enough free space between the stone packages anyway . The shape (T-profile) significantly simplifies and facilitates the laying work. Furthermore, the spacers according to the invention give the seedlings optimum space for root formation and also prevent the paving stones from shifting when firmly shaken.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Dabei zeigt

An embodiment of the invention is shown in the drawing. It shows
Fig. 1
in perspective a spacer and
Fig. 2
a laying example.

Der in Fig. 1 dargestellte Abstandhalter 1 für Pflastersteine 2 (Fig. 2) ist ein an beiden Enden, d.h. in Verlegestellung oben und unten, offenes T-förmiges Hohlprofil mit drei Hohlkammern 3, 4, von denen die mittlere Hohlkammer 4 größer als die beiden äußeren Hohlkammern 3 ist und den Steg des T-förmigen Hohlprofils bildet, das aus Kunststoff gespritzt wird. Die äußeren Hohlkammern 3 bilden die Flansche des T-förmigen Hohlprofils, wobei die Flansche und der Steg die gleiche Breite B haben, die der Fugenbreite bei den verlegten Pflastersteinen 2 entspricht.The spacer 1 for paving stones 2 (FIG. 2) shown in FIG. 1 is a T-shaped hollow profile that is open at both ends, ie in the installation position above and below with three hollow chambers 3, 4, of which the middle hollow chamber 4 is larger than the two outer hollow chambers 3 and forms the web of the T-shaped hollow profile, which is injection molded from plastic. The outer hollow chambers 3 form the flanges of the T-shaped hollow profile, the flanges and the web having the same width B, which corresponds to the joint width in the paving stones 2 laid.

Im Bereich der oberen Hälfte (in Verlegestellung) bilden zusätzliche Verbindungsstege 5 Trennwände zwischen den Hohlkammern 3, 4 und dienen der statischen Verfestigung der Abstandhalter 1, denn beim Festrütteln der frisch verlegten Pflastersteine 2 treten die größten Kräfte gerade in diesem oberen Bereich auf.In the area of the upper half (in the laying position), additional connecting webs 5 form partitions between the hollow chambers 3, 4 and serve to statically solidify the spacers 1, because when the freshly laid paving stones 2 are shaken firmly, the greatest forces occur precisely in this upper area.

Die Verlegung der Pflastersteine 2 und der Abstandhalter 1 kann entsprechend der Darstellung in Fig. 2 erfolgen, wobei die Fugen 6 zwischen den Pflastersteinen 2 sowie die Hohlkammern 3, 4 der Abstandhalter 1 mit Erde gefüllt und zur Grünbepflanzung eingesät werden. Da die Abstandhalter 1 nicht verrotten, geben sie praktisch für immer den Pflastersteinen 2 einen festen seitlichen Halt und verhindern auch ein Kippen derselben bei ungleichmäßiger Belastung.The laying of the paving stones 2 and the spacers 1 can take place as shown in FIG. 2, the joints 6 between the paving stones 2 and the hollow chambers 3, 4 of the spacers 1 being filled with soil and sown for green planting. Since the spacers 1 do not rot, they practically give the paving stones 2 a firm lateral hold forever and also prevent them from tipping over when the load is uneven.

Claims (2)
