Description
REVETEMENT-SUPPORT POREUX POUR TERRAINS DE POROUS SURFACE COATING FOR GROUNDS
SPORTSPORT
La présente invention a pour objet un revêtement-support poreux pour terrains de sport .The present invention relates to a porous support coating for sports grounds.
Il peut convenir à la plupart des types de terrains de jeu ou de sport, qu'ils soient intérieurs ou extérieurs, et s'applique par exemple aux terrains de basket-ball de football ou de volley-ball, aux courts de tennis de type terre battue, aux jeux de boules, ou encore aux arènes de tauromachie.It can be suitable for most types of playing or sports grounds, whether indoor or outdoor, and applies for example to football or volleyball basketball courts, tennis courts of the type clay, boules, or bullfighting arenas.
Les terrains de jeu ou de sport avec surface de jeu mobile ou non, en brique pilée, sable, schistes ou autres, présentent l'inconvénient de se déformer très rapidement et d'être rapidement rendus inutilisables, sauf intervention sérieuse, après la pluie ou le gel. Certaines méthodes de construction mettent en oeuvre, sous les revêtements de surface, un support rigide constitué par exemple de grave de ciment, de cendres ou d'enrobés poreux ou non. Ces techniques présentent l'inconvénient de ne pas pouvoir être humidifiées, d'où un inconfort très important pour les utilisateurs (glissage, poussière).Playgrounds or sports grounds with a mobile or non-mobile playing surface, made of crushed brick, sand, shale or other, have the disadvantage of being deformed very quickly and of being quickly rendered unusable, unless serious intervention is made, after rain or the freeze. Certain construction methods use, under the surface coatings, a rigid support consisting for example of cement gravel, ashes or porous or non-porous mixes. These techniques have the disadvantage of not being able to be humidified, hence a very significant discomfort for the users (sliding, dust).
C'est pourquoi un grand nombre de réalisations sont pourvues d'un drainage vertical constitué d'un système de récupération (drains) important sous la surface. Les désagréments qui peuvent s'ensuivreThis is why a large number of constructions are provided with vertical drainage consisting of a significant recovery system (drains) below the surface. The inconvenience that can ensue
(destruction de la porosité, colmatage ou bombage des drains entraînant une détérioration rapide de l'infrastructure) sont réels.
Le dispositif selon la présente invention supprime tous ces inconvénients. En effet, il permet de réaliser des terrains indéformables présentant une très bonne tenue dans le temps, insensibles au gel dans la plupart des cas, conservant une humidité permanente, d'un entretien facile et d'un remarquable confort d'utilisation dû en particulier à l'absence de poussière.(destruction of porosity, clogging or bulging of drains resulting in rapid deterioration of the infrastructure) are real. The device according to the present invention eliminates all these drawbacks. Indeed, it makes it possible to produce non-deformable soils with very good resistance over time, insensitive to frost in most cases, retaining permanent humidity, easy to maintain and a remarkable comfort of use due in particular the absence of dust.
Il est constitué d'une chape rigide microporeuse d'une structure lui permettant de maintenir une humidité permanente du revêtement de surface sous lequel elle est disposée, cette chape étant composée d'un mélange d'éléments structurels microporeux, d'éléments de calage nus, d'éléments frottants et de liants assurant une bonne cohésion de l'ensemble après coulage de la chape sur l'infrastructure du terrain.It consists of a rigid microporous screed with a structure allowing it to maintain a permanent humidity of the surface covering under which it is placed, this screed being composed of a mixture of microporous structural elements, of bare wedging elements , rubbing elements and binders ensuring good cohesion of the assembly after pouring the screed on the ground infrastructure.
Sur le dessin annexé, donné à titre d'exemple non limitatif d'une des formes de réalisation possible, la figure 1 représente la coupe verticale d'un élément de la surface d'un terrain de jeu ou de sport conforme à 1 ' invention.In the accompanying drawing, given by way of nonlimiting example of one of the possible embodiments, FIG. 1 represents the vertical section of an element on the surface of a playground or sports field in accordance with the invention .
Sur cette figure, on peut voir une chape microporeuse 1 disposée entre l'infrastructure 2 et le revêtement de surface 3 du terrain.In this figure, we can see a microporous screed 1 arranged between the infrastructure 2 and the surface coating 3 of the ground.
Les épaisseurs des différentes couches sont variables suivant les utilisations.The thicknesses of the different layers are variable depending on the uses.
La chape microporeuse 1 est rigide et sert de support du revêtement de surface 3 tout en permettant de faire office de réservoir d'humidité assurant ainsi une humidification progressive de ce revêtement.The microporous screed 1 is rigid and serves as a support for the surface coating 3 while making it possible to act as a moisture reservoir, thus ensuring progressive humidification of this coating.
Cette chape est formée d'éléments structurels microporeux (naturels ou non) d'éléments de calage nus
(poreux ou non, naturels ou non) d'éléments frottants (naturels ou non) et de liants assurant une bonne cohésion de l'ensemble. Ces composants sont mélangés et additionnés d'eau et éventuellement d'adjuvants, de façon à former un mortier apte à être coulé surThis screed is formed of microporous structural elements (natural or not) of bare wedging elements (porous or not, natural or not) rubbing elements (natural or not) and binders ensuring good cohesion of the whole. These components are mixed and added with water and optionally with additives, so as to form a mortar capable of being poured over
1 ' infrastructure 2 pour former un support rigide pour le revêtement de surface 3, que celui-ci soit de type "mobile" ou non.1 infrastructure 2 to form a rigid support for the surface coating 3, whether it is of the "mobile" type or not.
Les éléments microporeux, les éléments de calage et les éléments frottants seront constitués de pierre ponce, de basalte, de pouzzolane, de scories de haut-fourneau ou de matériaux similaires.The microporous elements, the wedging elements and the friction elements will consist of pumice stone, basalt, pozzolan, blast furnace slag or similar materials.
La composition de la chape 1 sera de préférence la suivante :The composition of the screed 1 will preferably be as follows:
- Eléments microporeux de granulométrie 6/20 mm 0 à 45 %- Microporous elements with a grain size of 6/20 mm 0 to 45%
- Eléments de calage microporeux de granulométrie 2/6 mm : 0 à 40 % ( Ensemble éléments microporeux + éléments de calage : 20 à 40 % )- Microporous wedging elements of 2/6 mm particle size: 0 to 40% (All microporous elements + wedging elements: 20 to 40%)
- Eléments frottants de granulométrie 0/1 mm 0 à 30 %- Friction elements with grain size 0/1 mm 0 to 30%
- Liants à base de laitier ou de scories 2 à 7 %- Binders based on slag or slag 2 to 7%
- adjuvant (cendres, chaux, etc) 0,5 à 3 %- adjuvant (ash, lime, etc.) 0.5 to 3%
- eau 1 à 10 %- water 1 to 10%
La chape 1 peut avantageusement être posée sur une in rastructure 2 souple constituée par exemple de tout venant et, pour peu que les pentes soient réalisées avec précision (pentes agréées par les diverses fédérations), permettre d'éviter tout système de drainage.
La structure et la rigidité de la chape 1 permettent de réaliser un traçage permanent en coulant des bandes de marquage définitives directement sur ce support .The screed 1 can advantageously be placed on a flexible in rastructure 2 constituted for example by all comers and, provided that the slopes are produced with precision (slopes approved by the various federations), make it possible to avoid any drainage system. The structure and the rigidity of the screed 1 make it possible to achieve permanent tracing by pouring definitive marking strips directly onto this support.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.
The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
