Abstract

Method of producing a surfacing for sports fields, in which first of all rubber granulates in various grain sizes are mixed with a binder based on polyurethane or another suitable plastic, this mixture is spread out on a firm foundation and is given a flat surface by rolling, skimming or a similar measure, and before the binder sets brick dust is distributed uniformly over the base layer, and in fact in such a quantity that only a portion of the brick dust makes a connection with the binder, while the rest of the brick dust lies loosely on the surface in order to make sliding possible.

Description

Process for the production of a covering for aport areas, in particular e Xennis courts, as well as a movable plate for laying on squares, in particular tennis courts The invention relates to a process for the production of a surface for aport courts, in particular tennis courts, in which rubber granulate in various grain sizes or dimensions is mixed with a polyurethane-based binder or another suitable plastic, this mixture on a solid base, e.g. asphalt , is spread and is given a flat surface by rolling, peeling or a similar measure and in which broken brick dust is evenly distributed on the base surface before the binder hardens, in such an amount that only a part of the broken brick dust with the binder a compound while the rest of the flour is left loosely on the surface to allow it to slide.

The rubber granulate mentioned can come in different Eörnunge: n or dimensions between 1 and 8 mm can be used. In very many cases a rubber granulate is used is used, which is used from the treads of used car tires.

However, it is essential that an elastic material in selected grain sizes or dimensions is used.

According to the invention it is necessary to control the curing of the binder in the base layer so that only part of the Broken brick flour forms a connection with the binder. This can be achieved in that the binder contains a very specific proportion of plastic, which preferably causes hardening to take place within a time interval of between 3 and 15 minutes.

With regard to the desired connection between the base layer and the broken brick dust, this has a grain size between 0 and 3 mm.

The invention also relates to a movable plate for laying on aport courts, especially tennis courts, where the stable floor of the plate consists of concrete or a similar hardened material. Located on this floor a base layer made of a mixture of rubber granules and a binder is based on polyurethane or a similar plastic. over the base layer there is another layer of broken brick dust, that with the binder of the base layer a bond is formed while the rest of the broken brick is loose Located on the base layer to prevent slipping during athletic movements facilitate.

In the drawing, the movable plate described is shown.

Fig.1 shows a plan view of a field that consists of movable plates is composed; Fig. 2 shows a partial view of the plate containing the various Reveals layers.

In the case of the movable plate shown, the bottom 2 of the plate is made 1 made of concrete or a similar load-bearing material.

On this floor 2 is a base layer 3, which consists of a Mixture of Gn = i granules and a binder based on polyurethane or a similar one EunststoPf exists. Above the base layer 3 there is another layer 4 from broken bricks, which entered into a connection with the binder of the base layer 7 is. A residue from the broken brick flour layer is loosely on the bound one Base layer to facilitate sliding movements.

Claims (5)

Claims 1. A method for producing a covering for aportplatz, in particular tennis courts, characterized in that initially rubber granules in different grain sizes or dimensions with a polyurethane-based binder or another suitable plastic is mixed, this mixture on a solid base, e.g. asphalt, is spread and by rolling, peeling or a similar measure is given a flat surface and before the binder hardens Broken brick dust is evenly distributed on the base layer, in a such an amount that only a portion of the broken bricks will bond with the binder while the rest of the flour remains loosely on the surface to form a To make sliding possible. 2. The method according to claim 1, characterized in that the rubber Granules in various grain sizes or dimensions between 1 and 8 mm are used finds. 3. The method according to claim 1, characterized in that the binder A plastic component is given such that the hardening takes place within a time interval takes between 3 and 15 minutes. 4. The method according to claim 1, characterized in that the broken bricks a grain size between 0 and 3 mm. 5. Movable plate for laying on sports fields, especially tennis courts, characterized in that the bottom (2) of the plate is made of concrete or the like there is stable material, there is a base layer (3) on this floor, made from a mixture of rubber granules and a polyurethane-based binder or a similar plastic and another Layer (4) consists of broken bricks, which with the binder of the base layer (3) a connection has been made and a remnant from the broken brick layer is formed loosely on the bonded base layer to facilitate slipping.
