Definitions
- a sports field surface is described according to the preamble of the patent claim, with a lower layer for damping impact effects on the surface and a thinner wear layer attached to it, both layers containing rubber chips and polyurethane.
- the lower or damping layer stabilized by a mesh of reinforcing iron contains, in addition to rubber chips that come from old vehicle tires and are bound with polyurethane, also mineral additives with which the elasticity of the layer can be adjusted to a desired value.
- Sports field coverings produced in this way have excellent properties.
- mineral additives Because they are made of grit, concrete gravel and / or sand, they are hygroscopic. The amount of moisture they contain therefore varies within certain limits. When producing the damping layer on the spot, it depends heavily on how and where the mineral additives were previously stored; it is quite possible that the moisture content changes during the production of the sports field surface, as this content may be lower in the later hours of the afternoon than in the morning at the start of work. However, this changes the properties of the covering.
- the invention therefore aims to replace this additive with a more suitable material and thus not only to simplify the manufacture, but if possible also to be able to prepare a part of the manufacturing process, so that only the actual installation has to be carried out on the spot.
- a sports field covering of the type mentioned at the outset, which meets these requirements, is characterized in that expanded expanded clay is added as an additive to the polyurethane or the rubber chips in the damping layer.
- the only drawing shows a perspective representation of a section of the sports field covering.
- this has the same structure as the sports field covering according to the aforementioned Swiss Patent No. 601567, namely a lower or damping layer 1, an upper or wear layer 2 and in between a stabilizing mesh 3 of reinforcing iron, which stabilizes the damping layer 1.
- Both layers contain rubber chips 4, which are made from old vehicle tires and bound with polyurethane.
- the entire covering is applied to a layer of gravel, not shown here, the so-called Reinplanie, which ensures the drainage of rain or melt water.
- the damping layer 1 previously contained mineral additives, it is now mixed with expanded expanded clay 5, which is preferably present in the form of small balls.
- This expanded clay has the following advantages.
- the lack of porosity not only prevents water absorption, but also absorbs some of the polyurethane. This can therefore be dosed precisely, which contributes to the further uniformity of the covering. In addition, significantly less polyurethane is required than before.
- Expanded expanded clay is more elastic than the mineral additives. This not only makes the covering more elastic, it also makes it less sensitive to extreme temperature fluctuations.
