Abstract
Description
Schüttgutbelag für Sportanlagen Bulky flooring for sports facilities
Für eine Reihe verschiedener Sportanlagen wird heute als Belag lose geschütteter Sand oder Asche verwendet. Derartige Sportanlagen sind z.B. Reitturnierplätze und Sprunggruben für Weitsprung. Zweck dieser losen Sandschüttung ist es, eine gute Dämpfung zu erzeugen, die z.B.For a number of different sports facilities, the covering is loose today used poured sand or ash. Such sports facilities are, for example, horse riding tournaments and jump pits for long jump. The purpose of this loose sand pour is to create a good one To generate attenuation, e.g.
für Weitsprunggruben, aber auch für Reitplätze unbedingt notwendig ist.Necessary for long jump pits, but also for riding arenas is.
Dieses Ziel wird jedoch bis heute von den üblichen Sandschüttungen, die vorwiegend aus mittelkörnigem Sand z.B. Rheinsand bestehen, nur unbefriedigend gelöst. So zeigt sich insbesondere bei Reitplätzen, daß infolge des hohen spezifischen Gewichtes des Sandes und der geringen Elastizität von Sandböden das Laufen auf derartigen Anlagen für die Pferde eine große Anstrengung bedeutet und zu einer starken Ermüdung führt. Sie beruht vor allem auf dem tiefen Einsinken der Hufe und dem hohen Kraftaufwand für das anschließende Herausziehen, was ganz besonders bei feuchtem Sand einen hohen Kraftaufwand erfordert.However, this goal is still today by the usual sand pouring, which mainly consist of medium-grain sand, e.g. Rhine sand, only unsatisfactory solved. It is evident, especially in riding arenas, that due to the high specific Weight of the sand and the low elasticity of sandy soils, walking on such Equipment for the horses means a great effort and a great deal of fatigue leads. It is mainly based on the deep sinking in of the hooves and the high expenditure of force for the subsequent pulling out, which is particularly high when the sand is damp Requires effort.
Die Erfindung hat es sich daher zuin Ziel gesetzt, ein Schiittgut zu entwickeln, das die beschriebenen Nachteile vermeidet, d.h. das spezifische Gewicht des Schüttgutes verringert und die Elastizität des Belags erheblich vergrößert. Dies wird nach dem Erfindungsvorschlag durch ein gleichmäßiges Beimischen eines relativ grobkörnigen Gummiabriebs in einem Anteil von etwa 20 - 50 Vol.% zu dem üblichen Rheinsand erreicht. Der gesamte gut gemischte Schüttgutbelag des Bodens wird hierdurch weicher und federnd, so daß die Eindringtiefe z.B. von Hufen verringert und dadurch und wegen des geringeren spezifischen Gewichtes des Misch-Schüttgutes der Kraftaufwand für das anschließende Herausziehen wesentlich herabgemindert wird.The invention has therefore set itself the goal of creating a piece of goods to develop that avoids the disadvantages described, i.e. the specific weight of the bulk material is reduced and the elasticity of the covering is considerably increased. According to the proposal of the invention, this is achieved by evenly adding a relatively coarse-grained rubber abrasion in a proportion of about 20-50% by volume to that usual Rhine sand reached. All of the well-mixed bulk material covering the floor becomes softer and more resilient, so that the depth of penetration, e.g. of hooves, is reduced and because of this and because of the lower specific weight of the mixed bulk material the effort required for the subsequent pulling out is significantly reduced.
Durch die beschriebene Beimischung eines grobkörnigen Gummiabriebs erfolgt gleichzeitig eine gute Staubbindung des Sandes, was vor allem bei trockener Witterung von Vorteil ist. Daneben wird die Zerkleinerung der Sandkörner, die z.B. bei jedem Hufschlag erfolgt, und damit die Erzeugung von Feinststaub erheblich verringert.By adding a coarse-grained rubber abrasion as described at the same time a good dust binding of the sand takes place, which is especially when it is dry Weather is an advantage. In addition, the crushing of the sand grains, which e.g. occurs with every hoof beat, and thus the generation of fine dust is considerably reduced.
Die Kapillarität des Gemisches entspricht dagegen vollkommen der des bekannten Rheinsandes, so daß die Sickerfähigkeit die entscheidend für das schnelle Abtrocknen des Bodens nach heftigen Regengussen ist, nicht verandert wird.The capillarity of the mixture, on the other hand, corresponds completely to that of the known Rhine sand, so that the seepage capacity is the decisive factor for the rapid drying of the soil after heavy downpours has not changed will.
Die beschriebene lilethode zur lIerstellung eines federnden Schüttgutbelages eignet sich außer für Reitsportanlagen beispielsweise auch für Aschenbahnen in Sportstadien, da hierdurch auch die Gefahr von schweren Verletzungen bei Stürzen erheblich verringert wird.The described method for creating a resilient bulk material covering In addition to equestrian facilities, it is also suitable, for example, for cinder tracks in sports stadiums, as this also significantly reduces the risk of serious injuries in the event of a fall will.
Zur Beimischung zu dem mittelkörnigen Sand ist z.B. Gummiabrieb, wie er beim Abschleifen von Altreifen vor einer Runderneuerung der Laufflächen entsteht, besonders gut geeignet. Da dieser Abrieb zu einem sehr geringen Preis zur Verfügung steht, kann durch seine Verwendung die gewünschte Schüttgutmischung sehr wirtschaftlich hergestellt werden.To be admixed with the medium-grain sand, for example, rubber abrasion, such as it arises when grinding old tires before retreading the treads, particularly suitable. Because this abrasion is available at a very low price is available, the desired bulk material mixture can be very economical thanks to its use getting produced.
Der Mischung aus Sand und Gummiabrieb können auch noch weitere Komponenten zugesetzt werden, z.B. um die gesamte Mischung gut fließfähig zu erhalten, so daß auf die Dauer kein Zusammenbacken einzelner Körner erfolgt. Ein derartiges Mittel ist z.B. Talkum.The mixture of sand and rubber abrasion can also have other components can be added, e.g. to keep the entire mixture free-flowing, so that In the long run there is no caking of individual grains. Such a means is e.g. talc.
