Abstract
Description
Die Erfindung betrifft einen Betonformstein für die Pflasterung von Straßen und Plätzen.The invention relates to a concrete block for the Paving streets and squares.
Für die Pflasterung von Straßen und Plätzen hat die Ver wendung von Betonformsteinen weite und zunehmende Verbrei tung gewonnen.For the paving of streets and squares, the Ver Use of concrete blocks wide and increasing spread won.
In klimatologischer Hinsicht wird es aber immer stärker als Nachteil empfunden, daß eine zunehmende Versiegelung der natürlichen Bodenüberfläche durch eine Pflasterung zu einer Aufheizung des Stadtklimas führt, da Pflastersteine den Wärmeaustausch zwischen Boden und Atmosphäre bei Tag und Nacht stark in der Weise negativ beeinflußen, daß bei Tage eine höhere Aufheizung der Bodenfläche eintritt, die bei Nacht noch langsamer abgebaut wird als bei Naturböden üblich.In climatological terms, however, it is getting stronger perceived as a disadvantage that an increasing sealing the natural surface of the soil through paving leads to a heating up of the city climate, because paving stones the heat exchange between soil and atmosphere during the day and negatively influence night in such a way that at Days a higher heating of the floor area occurs that degrades even more slowly at night than with natural soils common.
Der Erfindung liegt die Aufgabe zugrunde, diesen nachteili gen klimatologischen Effekt von Betonformsteinen abzumildern bzw. zu beseitigen.The invention has for its object this disadvantage mitigate the climatological effect of concrete blocks or eliminate.
Gelöst wird diese Aufgabe nach der Erfindung dadurch, daß ein Betonformstein hergestellt wird, der gekennzeichnet ist durch eine Gemischzusammensetzung aus ca. 10 Gewichtspro zenten Sand der Korngröße 0 bis 2 mm, ca. 15 Gewichtsprozen ten Zement, ca. 5 Gewichtsprozenten Wasser und Zuschlagsstoffen (Splitt, Blaubasalt, Kies, o.a.) mit einem Anteil von 5 bis 8 mm und zwei Anteilen von 2 bis 5 mm Korngröße.This object is achieved according to the invention in that a shaped concrete block is produced that is marked due to a mixture of approx. 10 wt zenten sand with a grain size of 0 to 2 mm, approx. 15 percent by weight cement, approx. 5 percent by weight water and aggregates (Grit, blue basalt, gravel, etc.) with a share of 5 to 8 mm and two parts of 2 to 5 mm grain size.
Ein Betonformstein mit einer solchen Gemischzusammensetzung stellt ein offenporiges, wasserdurchlässiges Bauelement dar, das den Wasserdurchgang nicht in dem Ausmaß behindert, wie es bei einer Natursteinpflasterung oder einer Pflasterung aus herkömmlichen Betonformsteinen der Fall ist.A concrete block with such a mixture composition represents an open-pore, water-permeable component, that doesn’t hinder the passage of water to the extent that it does with a natural stone paving or paving conventional concrete blocks is the case.
Der beim erfindungsgemäßen Betonformstein ermöglichte Wasser durchgang von oben nach unten führt zu einer teilweisen und vermehrten Aufnahme von Regenwasser im Erdreich unterhalb der Pflasterung und vermindert somit die Menge des Abflußwassers. Die Möglichkeit eines Wasserdurchgangs von unten nach oben führt dagegen zu einem Kühleffekt, da ein solcher poröser wasserdurchlässiger Betonformstein einen dauernden Wasserdurch tritt von unten nach oben zuläßt und eine Verdunstung des hin durch getretenen Wassers ermöglicht. Da Wasser eine hohe Ver dampfungswärme erfordert, wird den Betonformsteinen aufgrund dieser dauernden Verdunstung eine große Wärmemenge entzogen, die gesamte Pflasterung somit ständig gekühlt.The water made possible in the concrete block according to the invention passage from top to bottom leads to a partial and increased uptake of rainwater in the soil below the Paving and thus reduces the amount of drain water. The possibility of water passage from the bottom up leads to a cooling effect, because such a porous one permeable concrete block a permanent water passage occurs from the bottom up and allows evaporation of the made possible by stepped water. Since water has a high ver heat of vaporization is required due to the concrete blocks a large amount of heat was removed from this permanent evaporation, the entire paving is therefore constantly cooled.
Der beschriebene Betonformstein besitzt also gewissermaßen eine eingebaute Kühleinrichtung und bewirkt in sehr kosten sparender einfacher Weise eine Verbesserung des Stadtklimas.The concrete block described thus has, so to speak a built-in cooling device and results in very cost an easier way to improve the urban climate.
