Support plates for road caps

Die Neuerung betrifft Tragplatten oder auch Unterlagsplatten für Wasserleitungen DIN 4055 (Fig. 1), DIN 4056 (Fig. 2), DIN 4057/38 ( Fig.2), DIN 4057/74 ( Fig.2), Gasleitungen DIN 4058 ( Fig.2), DIN 4059 ( Fig.2), und Ferngasleitungen DIN 3581 ( Fig.2).Die hergestellten Tragplatten dienen zur Aufnahnne von Straßenkappen in Straßen oder Gehwegen als ringförmige mit einer der am unterem Rand der Straßenkappe zugewiesenen Profilierung.The innovation concerns support plates or base plates for water pipes DIN 4055 (Fig. 1), DIN 4056 (Fig. 2), DIN 4057/38 (Fig.2), DIN 4057/74 (Fig.2), gas pipes DIN 4058 (Fig.2), DIN 4059 (Fig.2), and long-distance gas pipes DIN 3581 (Fig.2).The support plates produced are used to hold street caps in streets or sidewalks as ring-shaped ones with a profile assigned to the lower edge of the street cap.

Tragplatten aus Beton sind bekannt und haben die Aufgabe, den Straßenkappen einen standsicheren und tragfähigen Übergang zur Tragschicht des Straßen- oder Gehwegs zu gewährleisten.Concrete base plates are well known and have the task of ensuring that the street caps have a stable and load-bearing transition to the base layer of the road or sidewalk.

Zur Zeit werden Tragplatten aus Beton oder Kunststoff hergestellt.Currently, support plates are made of concrete or plastic.

Die heute hergestellten Tragplatten werden aus herkömmlichem Beton B 25 hergestellt.The supporting slabs manufactured today are made of conventional concrete B 25.

Tragplatten aus herkömmlichem Beton sind aufgrund der geringen Druckfestigkeit und Biegezugfestigkeit sehr dick und haben dadurch ein hohes Gewicht. Dies bedingt neben hohen Transportkosten eine erhebliche körperliche Belastung für den Verarbeiter.Due to their low compressive strength and flexural strength, base plates made of conventional concrete are very thick and therefore very heavy. In addition to high transport costs, this places a considerable physical strain on the installer.

Kunststoffplatten sind zwar leicht,haben aber den Nachteil, dass sie sich bei Sonneneinstrahlung sehr stark verziehen, und es ist daher schwer sie beim Einbau planflächig zu verarbeiten. Außerdem sind sie in der Herstellung durch den verwendeten Rohstoff (Mineralölprodukt) sehr teuer. Neben den rohstoffbedingten, sehr teuren Herstellungskosten, ist eine kosten intensive Lagerung, da Sonnen- und Temperaturschutz erforderlich ist, notwendig.Although plastic panels are light, they have the disadvantage that they warp significantly when exposed to sunlight, making it difficult to work them flat during installation. They are also very expensive to manufacture due to the raw material used (mineral oil product). In addition to the very expensive manufacturing costs due to the raw materials, they also require costly storage as they require protection from the sun and temperature.

Ziel ist es Tragplatten herzustellen, die leicht sind, einfache Lagerungs- und Transportkonditionen aufweisen und zudem preisgünstig sind.The aim is to produce support plates that are lightweight, easy to store and transport and are also inexpensive.

Der Neuerung liegt die Aufgabe zu Grunde, eine Betontragplatte herzustellen, die unter Berücksichtigung der geforderten Festigkeiten leichter ist, um damit die körperlichen Belastungen des Verarbeiters sehr gering zu halten.The innovation is based on the task of producing a concrete base plate that is lighter while taking into account the required strengths in order to keep the physical strain on the processor as low as possible.

Es liegt im Rahmen der Neuerung, dass die Tragplatten aus einem selbstverdichtenden Spezialbeton hergestellt werden. Dieser Beton hat eine mindestens dreifach höhere Druckfestigkeit als Standardbeton. Auch die Biegezugfestigkeit ist mindestens um das dreifache höher als bei Standardbeton.As part of the innovation, the supporting slabs are made from a special self-compacting concrete. This concrete has a compressive strength that is at least three times higher than standard concrete. The flexural strength is also at least three times higher than standard concrete.

Die Verwendung dieses neuartigen Betons gewährleistet eine ausreichend hohe Festigkeit, um eine standsichere Auflagefläche zu gewährleisten.The use of this new type of concrete ensures sufficient strength to ensure a stable support surface.

Es werden die Vorteile der bisherigen Herstellungsverfahren aus Beton und Kunststoff vereint.The advantages of previous manufacturing processes using concrete and plastic are combined.

Durch die Verwendung eines selbstverdichtenden Betons mit einer gezielten Betonrezeptur ist es möglich, Tragplatten herzustellen, die eine wesentlich schlankere Bauform zulassen.By using self-compacting concrete with a specific concrete recipe, it is possible to produce support slabs that allow for a much slimmer design.

Anhand der nachfolgenden Beispiele sollen die Vorteile der Erfindung näher erläutert werden:The following examples will illustrate the advantages of the invention in more detail:

Eine aus normalem Beton hergestellte Tagplatte für die Straßenkappen DIN 4055 mit einer Größe von 540x450x70 hat ein Gewicht von etwa 25kg. Die in der Neuerung beschriebene Tragplatte 4055 aus selbstverdichtendem Beton, die in gleicher Größe, aber in geringerer Höhe der Platte hergestellt wird, hat ein Gewicht von weniger als 7,5 kg.A base plate made of normal concrete for the DIN 4055 street caps with a size of 540x450x70 weighs around 25 kg. The base plate 4055 made of self-compacting concrete described in the innovation, which is manufactured in the same size but at a lower height of the plate, weighs less than 7.5 kg.

Tragplatten 4056 und 4057 wiegen 14 kg bzw. 11 kg. Die beschriebenen Tragplatten aus selbstverdichtendem Beton wiegen weniger als 3,5 kg.Base plates 4056 and 4057 weigh 14 kg and 11 kg respectively. The base plates made of self-compacting concrete described weigh less than 3.5 kg.

Durch diese sehr hohen Gewichtsersparnisse ist die körperliche Belastung des Verarbeiters sehr viel geringer als im Vergleich zu herkömmlichen Betontragplatten .Due to these very high weight savings, the physical strain on the installer is much lower than with conventional concrete support slabs.

Die zugewiesene Profilierung ist für verschiedene Straßenkappen zu verwenden. So ist die Profilierung 1 für Straßenkappen DIN 4055, Profilierung 2 für Straßenkappen DIN 4056+4058+3581 und die Profilierung 3 für Straßenkappen DIN 4057 Modell 74, sowie Profilierung 4 für Straßenkappen 4057/38 und 4059 gedacht ist.The assigned profiling is to be used for different surface caps. Profiling 1 is intended for surface caps DIN 4055, profiling 2 for surface caps DIN 4056+4058+3581 and profiling 3 for surface caps DIN 4057 model 74, as well as profiling 4 for surface caps 4057/38 and 4059.

Es werden Bewehrungen aus Stahl in Form von Bewehrungsringen oder einer Faser, sei es Stahl-, Kunststoffoder Glasfaser, so wie es auch Stand der Technik ist, verwendet.Reinforcements made of steel in the form of reinforcement rings or a fibre, be it steel, plastic or glass fibre, are used, as is the state of the art.

Ebenso führt die Gewichts- und Volumenersparnis zu erheblich reduzierten Transportkosten. Hierdurch, sowie durch das verwendete Material ( keine Mineralölprodukte) stellt die Erfindung auch aus ökologischer Sicht einen erheblichen Fortschritt dar.The weight and volume savings also lead to significantly reduced transport costs. This, as well as the material used (no mineral oil products), also means that the invention represents a significant advance from an ecological point of view.

Der Werkstoff Beton bietet schließlich den Vorteil einer einfachen Lagerung, beispielsweise auch im Freien.Finally, the material concrete offers the advantage of easy storage, for example outdoors.
