Description

L'invention concerne un terrain de sport reposant sur une fondation et constitué d'une couche de sable naturelle melangé avec des particules fibreuses d'une quantité d'au moins 1% du poids de la couche sur laquelle est placée une pelouse de gazon artificiel.The invention relates to a sports ground resting on a foundation and consisting of a layer of natural sand mixed with fibrous particles of an amount of at least 1% of the weight of the layer on which a lawn of artificial grass is placed. .

Un tel terrain de sport est présenté par EP-A 0 136 747. Dans celle-ci est décrit un terrain de gazon artificiel, constitué d'un mélange sable non fractionné et d'au moins 1 % en poids de matières fibreuses.Such a sports field is presented by EP-A 0 136 747. In it is described an artificial grass field, consisting of an unfractionated sand mixture and at least 1% by weight of fibrous materials.

Les grains de sable sont plus ou moins agglomérés du fait de la présence de ces matières fibreuses, de préférence des fibres textiles (polypropène ou nylon) ou fibres de verre, ce qui leur donne une structure de lit.The grains of sand are more or less agglomerated due to the presence of these fibrous materials, preferably textile fibers (polypropene or nylon) or glass fibers, which gives them a bed structure.

Le but recherché est de procurer au terrain une telle capacité d'amortissement et d'élasticité, que lors des activités sportives on puisse se croire sur un gazon naturel, une capacité d'amortissement restant constante après un longtemps d'usage.The aim is to provide the ground with such a damping and elasticity capacity, that during sports activities one can believe oneself on natural grass, a damping capacity remaining constant after a long time of use.

Le but de l'invention est de réaliser un terrain de sport, qui, outre l'amortissement requis, ait aussi la faculté réelle de reprendre sa forme et soit expérimenté comme agréable par le sportif.The object of the invention is to provide a sports ground, which, in addition to the required amortization, also has the real ability to regain its shape and is experienced as pleasant by the sportsman.

Ce but est atteint avec l'invention, du fait que les particules fibreuses sont des rognures ou de fibres d'élastomère, lesquelles rognures ou fibres représentent 10 à 50% du poids de la couche mélangé.This object is achieved with the invention, because the fibrous particles are trimmings or elastomeric fibers, which trimmings or fibers represent 10 to 50% of the weight of the mixed layer.

Les rognures ou les fibres d'élastomère peuvent, au contraire des fibres utilisées dans les terrains de sport actuels, être enforcées et se redresser. Le terrain de sport bénéficie ainsi suivant l'invention, outre de la capacité d'amortissement, de la faculté de reprendre sa forme et les enforcements se rétablissent ainsi d'eux-mêmes. Ces rognures ou fibres d'élastomères offrent, outre la fonction déjà obtenue avec les fibres textiles, leur propriété élastique, ce qui donne au terrain un caractère propre technique-sportif.Trims or elastomer fibers can, unlike fibers used in today's sports fields, be reinforced and straighten. The sports field thus benefits according to the invention, in addition to the damping capacity, the ability to regain its shape and the reinforcements thus recover by themselves. These clippings or fibers of elastomers offer, in addition to the function already obtained with textile fibers, their elastic property, which gives the terrain a specific technical-sporting character.

Selon une forme optionnelle de l'exécution de l'invention, le terrain de sport est tel que le sable dans le mélange consiste en partie en sable de laitier hydraulique. Le rapport de poids entre le sable de laitier hydraulique et le sable naturel est de préférence d'environ 3:7. Le sable naturel a, de préférence, une gradation de 0,2 à 5,6 mm.According to an optional embodiment of the invention, the sports field is such that the sand in the mixture partly consists of hydraulic slag sand. The weight ratio between hydraulic slag sand and natural sand is preferably about 3: 7. Natural sand preferably has a gradation of 0.2 to 5.6 mm.

Selon une autre forme d'exécution, le terrain de sport est réalisé de telle façon que les rognures de caoutchouc ou les fibres représentent 20 à 40% du poids du mélange. Les rognures de caoutchouc ou les fibres sont de préférence de forme allongée, d'une longueur de 10 à 40 mm et d'une épaisseur de 1 à4mm.According to another embodiment, the sports field is made in such a way that the rubber shavings or the fibers represent 20 to 40% of the weight of the mixture. The rubber trimmings or the fibers are preferably elongated, 10 to 40 mm long and 1 to 4 mm thick.

Ces rognures de caoutchouc peuvent être des retailles de caoutchouc neuf, de caoutchouc usagé ou de vieux pneus.These rubber scraps can be scrap of new rubber, used rubber or old tires.

Pour obtenir une couche de mélange régulièrement répartie et assurer un bon drainage, il est important que soit apportée une couche répartissant la pression. Cela est réalisé en plaçant entre la couche de mélange et un lit de sable formant la fondation une pellicule de séparation constituée de fibres textiles, plus particulièrement un tapis fibreux non-tissé. Cette même pellicule de séparation peut aussi être apportée entre la couche supérieure ou le gazon artificiel et la couche de mélange.To obtain a uniformly distributed layer of mixture and ensure good drainage, it is important that a pressure-distributing layer is provided. This is achieved by placing a separation film made of textile fibers, more particularly a non-woven fibrous mat, between the mixture layer and a bed of sand forming the foundation. This same separation film can also be provided between the upper layer or the artificial turf and the mixture layer.

Une telle pellicule est connue sous le nom de géo- pellicule@ et est fréquemment appliquée dans les constructions routières et hydrauliques pour la stabilisation des terrains où se présentent des problèmes d'humidité, tant lors de charge statique que lors de charge dynamique.Such a film is known under the name of geoparticle @ and is frequently applied in road and hydraulic constructions for the stabilization of grounds where moisture problems arise, both during static and dynamic loading.

L'application dans le cadre de l'invention assure, outre l'évacuation des eaux le maintien de la forme et des propriétés de la couche de mélange en fibres d'élastomère située sous le gazon artificiel. Il importe que la base sous cette couche reste bien plane pour maintenir les propriétés d'amortissement et la planéité requise.The application in the context of the invention ensures, in addition to the evacuation of water, the maintenance of the shape and properties of the layer of mixture of elastomer fibers located under the artificial turf. It is important that the base under this layer remains flat to maintain the damping properties and the required flatness.

Il faut remarquer qu'il est courant d'utiliser du caoutchouc pour donner de l'élasticité au gazon artificiel d'un terrain de sport. Ce sont par exemple surtout des tapis de caoutchouc, lesquels sont collés sur une base lisse.Note that it is common to use rubber to give elasticity to the artificial turf of a sports field. These are, for example, mainly rubber mats, which are glued to a smooth base.

Il faut remarquer aussi qu'il est connu du brevet français 1 549 667 de construire un terrain de sport avec un mélange des grains d'élastomère avec du sable mais cette couche est couvert d'un revêtement a liant bitumineux perméable à l'eau donnant au surface des caractériques de friction et d'élasticité différent du terrain de l'invention dans lequel la pelouse de gazon est directement ou par l'intermédiaire d'un tapis fibreux supportée par la couche de sable avec ledit quantité des rognures ou fibres d'élastomère.It should also be noted that it is known from French patent 1,549,667 to build a sports field with a mixture of elastomer grains with sand, but this layer is covered with a coating of bituminous binder permeable to water giving at the surface of the characteristics of friction and elasticity different from the terrain of the invention in which the lawn of grass is directly or by means of a fibrous mat supported by the layer of sand with said quantity of parings or fibers of elastomer.

Du DE-A 3 313 329 il est connu de combiner 10-30% particules de caoutchouc avec 50-80% des pi- railles mais avec un liant et cette surface peut être couvert avec une pelouse de gazon artificielle.From DE-A 3 313 329 it is known to combine 10-30% rubber particles with 50-80% of the straws but with a binder and this surface can be covered with an artificial turf lawn.

Le liant donne au terrain des caractéristiques différentes.The binder gives the terrain different characteristics.

L'épaisseur de la couche de fibres-sable ou couche de mélange est de préférence de 50 à 100 mm.The thickness of the fiber-sand layer or mixture layer is preferably 50 to 100 mm.

L'invention est représentée à l'aide du schéma.The invention is shown using the diagram.

Sur ce schéma, la couche de sable est indiquée par 1, sur laquelle est apportée une pellicule de séparation 2. Là-dessus repose la couche de mélange 3, constituée de sable naturel mélangé avec du sable de laitier hydraulique et des rognures de caoutchouc 4. Cette couche est ensuite recouverte d'une autre pellicule de séparation 5 sur laquelle est finalement posé un gazon artificiel 6.In this diagram, the layer of sand is indicated by 1, on which a separation film is provided 2. On it rests the layer of mixture 3, consisting of natural sand mixed with hydraulic slag sand and rubber trimmings 4 This layer is then covered with another separation film 5 on which an artificial grass 6 is finally laid.
