Abstract

The floor has a base layer (2) arranged on a stabilized floor base (1) and constituted of compacted rubber aggregates connected by a binder e.g. polymerizable resin. The base layer has a thickness ranging between 2-12 millimeters, and comprises a rough upper surface (6) provided with multidirectional striations. A surface layer (3) is constituted of free rubber aggregates, and has a thickness ranging between 10-50 millimeters, where the surface layer covers the base layer. The aggregates are obtained by recycling worn tires. An independent claim is also included for a method of forming an equestrian floor.

Description

La présente invention concerne le domaine général de l'équitation. Elle concerne plus particulièrement une structure de sol équestre ainsi que son procédé de réalisation.The present invention relates to the general field of riding. It relates more particularly to an equestrian floor structure and its method of production.

Très souvent, les sols de carrières et de manèges équestres sont constitués d'une couche de sable ou de micro-sable, étalée sur un fond de sol stabilisé formé de pierres et/ou de graves compactés.Very often, the floors of quarries and equestrian rides consist of a layer of sand or micro-sand, spread on a bottom of stabilized soil made of stones and / or compacted gravel.

Cependant, les surfaces de ce genre nécessitent d'être régulièrement entretenues (arrosage, nivellement, réalimentation ...) ce qui les rend relativement coûteuses tant en matières premières qu'en main d'oeuvre.
D'autre part, leurs propriétés d'amortissement, bien qu'efficaces, n'apportent pas un confort et une sécurité optimales aux animaux et aussi à leurs cavaliers.
En outre, le sable est bien connu pour entraîner une abrasion assez rapide des fers des chevaux, ce qui nécessite leurs remplacements assez fréquents.However, surfaces of this kind require regular maintenance (watering, leveling, replenishment ...) which makes them relatively expensive both raw materials and labor.
On the other hand, their damping properties, although effective, do not provide comfort and optimum safety for animals and their riders.
In addition, sand is well known to cause fairly rapid abrasion of horse irons, which requires their replacement fairly often.

On connaît d'autre part, par le document EP-1 486 612 , un sol équestre constitué d'un soubassement surmonté d'une première couche de granulats de caoutchouc EPDM agglomérés, elle-même surmontée d'une seconde couche de granulats de caoutchouc EPDM agglomérés, moins dure que la première, elle-même surmontée d'une couche de granulats de caoutchouc EPDM libres, en vrac.On the other hand, we know from the document EP-1,486,612 , an equestrian floor consisting of a base surmounted by a first layer of agglomerated EPDM rubber granules, itself surmounted by a second layer of agglomerated EPDM rubber granules, less hard than the first one, itself surmounted by a layer of free EPDM rubber granules, in bulk.

Or, une telle structure de sol est relativement complexe à réaliser puisqu'il est prévu deux couches de granulats agglomérés sur le soubassement, avant la dépose de la couche supérieure en vrac.
En outre, la couche de granulats libres est relativement mobile sur la surface de la seconde couche agglomérée, ce qui limite ses capacités de maintien et ce qui nuit par conséquent à la stabilité et au confort des animaux lors de leurs déplacements (ceci malgré la présence d'interstices entre les granulats au niveau de la surface de la seconde couche agglomérée).However, such a soil structure is relatively complex to achieve since there are two layers of aggregates agglomerated on the base, before the removal of the top layer in bulk.
In addition, the layer of free aggregates is relatively mobile on the surface of the second agglomerated layer, which limits its holding capacity and which therefore adversely affects the stability and comfort of the animals during their movements (this despite the presence interstices between the aggregates at the surface of the second agglomerated layer).

La présente invention propose une nouvelle structure de sol équestre, économique, non abrasive, ayant une bonne tenue et présentant en outre des caractéristiques d'amortissement et de rebond intéressantes.The present invention provides a new equestrian floor structure, economic, non-abrasive, having good strength and further having interesting damping and rebound characteristics.

A cet effet, le sol équestre conforme à l'invention comprend :

  • un fond de sol stabilisé,
  • une couche de base ménagée sur ledit fond de sol, laquelle couche de base présente une épaisseur comprise entre 15 et 55 mm, et est constituée de granulats de caoutchouc compactés solidarisés par un liant, laquelle couche de base comporte une surface supérieure munie de striures pluridirectionnelles lui conférant un caractère rugueux, et
  • une couche de surface constituée de granulats de caoutchouc libres, étalés sur ladite surface rugueuse munie de striures pluridirectionnelles, laquelle couche de surface a une épaisseur comprise entre 10 et 100 mm.
For this purpose, the equestrian floor according to the invention comprises:
  • a stabilized soil floor,
  • a base layer provided on said floor bottom, which base layer has a thickness of between 15 and 55 mm, and consists of compacted rubber granules bonded with a binder, which base layer comprises a upper surface with multi-directional streaks giving it a roughness, and
  • a surface layer of free rubber granules, spread over said roughened surface having multi-directional striations, which surface layer has a thickness of between 10 and 100 mm.

On obtient une surface stable, qui ne nécessite pas d'arrosage contrairement aux surfaces antérieures sableuses, et qui est en outre bien acceptée par les animaux. Un tel revêtement de sol s'avère très confortable à l'impact du fait de ses bonnes qualités d'amortissement et de rebond. La couche supérieure formée de granulats libres, en appui sur la couche de base à surface supérieure rugueuse, autorise un certain degré de rotation aux pieds du cheval, ce qui permet à ce dernier de bien contrôler ses appuis tout en ménageant ses articulations. La couche de base en granulats de caoutchouc liés limite les affouillements créés par les sabots des chevaux et confère au sol des caractéristiques de rebond qui améliorent la performance sportive du cheval. La conjonction de cette couche de base avec striures pluridirectionnelles et de la couche de surface en granulats libres apporte de la souplesse et conserve néanmoins une résistance au cisaillement adaptée à la pratique sportive.A stable surface is obtained, which does not require watering, unlike sandy anterior surfaces, and which is moreover well accepted by the animals. Such flooring is very comfortable on impact because of its good damping and rebound qualities. The upper layer formed of free aggregates, resting on the base layer with rough upper surface, allows a certain degree of rotation to the horse's feet, which allows the latter to control his supports well while sparing his joints. The base layer made of bonded rubber granules limits scouring created by horse hooves and gives the ground bounce characteristics that enhance the horse's athletic performance. The combination of this base layer with multi-directional striations and the surface layer of free aggregates provides flexibility and nevertheless retains a shear strength adapted to the sport.

Les granulats de caoutchouc utilisés proviennent de préférence de pneumatiques usagés, ce qui limite le coût matière du sol obtenu. En particulier, l'utilisation de pneumatiques usagés non réutilisables (PUNR) provenant de la filière de la Société ALIAPUR garantit - une teneur en élastomère supérieure à 45 % pour assurer les performances d'amortissement, - une teneur en charge renforçante supérieure à 25 % assurant une résistance à l'usure par frottement, et - une chimie complexe permettant une non dégradation aux UV, ainsi que - l'absence de fils métalliques pouvant occasionner des gênes ou blessures pour les chevaux ou les cavaliers.The rubber granulates used are preferably from used tires, which limits the material cost of the soil obtained. In particular, the use of non-reusable used tires (PUNR) from the ALIAPUR Company's chain guarantees - an elastomer content greater than 45% to ensure damping performance, - a reinforcing filler content of greater than 25% providing resistance to chafing, and - complex chemistry allowing non-degradation to UV, as well as - the absence of metal wires which may cause annoyance or injury to horses or riders.

La couche de base est de préférence constituée de granulats de caoutchouc dont au moins 90 % en masse ont une granulométrie comprise entre 2 et 12 mm.The base layer is preferably composed of rubber granules of which at least 90% by mass have a particle size of between 2 and 12 mm.

Selon une forme de réalisation particulièrement intéressante, cette couche de base est constituée d'un mélange compacté de granulats de caoutchouc et d'une résine, ladite résine représentant entre 12 et 25 % du poids desdits granulats.According to a particularly interesting embodiment, this base layer consists of a compacted mixture of rubber granules and a resin, said resin representing between 12 and 25% of the weight of said aggregates.

Selon encore une autre particularité, la profondeur de la majorité des striures pluridirectionnelles ménagées sur la surface de la couche de base est au maximum de 10 mm.According to yet another particularity, the depth of the majority of the pluridirectional striations formed on the surface of the base layer is at most 10 mm.

L'épaisseur de la couche de surface, constituée de granulats libres, est d'autre part de préférence comprise entre 20 et 40 mm. Cette couche de surface est de préférence constituée de granulats de caoutchouc dont au moins 90 % en masse ont une granulométrie comprise entre 1 et 10 mm.The thickness of the surface layer, consisting of free aggregates, is on the other hand preferably between 20 and 40 mm. This surface layer is preferably consisting of rubber granules of which at least 90% by mass has a particle size of between 1 and 10 mm.

Le fond de ce sol équestre est avantageusement constitué :

  • d'une sous-couche empierrée, compactée, ayant une portance minimale de 30 MPa, et
  • d'une surcouche compactée, constituée de graves de type 0/10 à 0/20, dont l'épaisseur est comprise entre 10 et 15 cm.
The bottom of this equestrian soil is advantageously constituted:
  • a compacted, slabbed sub-layer with a minimum lift of 30 MPa, and
  • a compacted overcoat, consisting of 0/10 to 0/20 type bass, whose thickness is between 10 and 15 cm.

Selon une forme de réalisation préférée, le procédé de réalisation de ce sol équestre consiste :

  • à réaliser un fond de sol stabilisé, à base de pierres et/ou de graves compactées,
  • à réaliser un mélange de granulats de caoutchouc et de liant de type résine polymérisable,
  • à compacter ledit mélange granulats/résine sur ledit fond de sol, pour obtenir la couche de base,
  • à réaliser un griffage pluridirectionnel de la surface supérieure de ladite couche de base, pour obtenir des striures de rugosité, ceci avant la polymérisation complète de la résine,
  • puis, après polymérisation de la résine, à rapporter sur la couche de base des granulats de caoutchouc libres, pour former la couche de surface.
According to a preferred embodiment, the method of producing this equestrian floor consists of:
  • to achieve a stabilized soil base, based on stones and / or compacted gravels,
  • to produce a mixture of rubber granules and polymerizable resin binder,
  • compacting said granulate / resin mixture on said bottom of soil, to obtain the base layer,
  • performing a multidirectional scratching of the upper surface of said base layer to obtain roughness striations, before the complete polymerization of the resin,
  • then, after polymerization of the resin, to report on the base layer free rubber granules, to form the surface layer.

L'invention sera encore illustrée, sans être aucunement limitée, par la description suivante en liaison avec le dessin annexé correspondant à une coupe verticale d'une forme de réalisation possible du sol équestre conforme à l'invention.The invention will be further illustrated, without being limited in any way, by the following description in conjunction with the appended drawing corresponding to a vertical section of a possible embodiment of the equestrian floor according to the invention.

Tel qu'illustré sur la figure annexée, la structure de sol conforme à l'invention est constituée d'un fond de sol stabilisé 1, recouvert d'une couche de base 2 formée de granulats de caoutchouc compactés solidarisés par un liant, elle-même recouverte d'une couche de surface 3 formée de granulats libres de caoutchouc.As illustrated in the attached figure, the floor structure according to the invention consists of a stabilized floor bottom 1, covered with a base layer 2 formed of compacted rubber granules secured by a binder, itself even covered with a surface layer 3 formed of granules free of rubber.

Le fond de sol stabilisé 1 a une structure classique. Il est constitué - d'une sous-couche 4 formée de pierres/cailloux compactés, présentant une portance minimale de 30 MPa, et - d'une surcouche 5 formée de graves concassées compactées.The stabilized soil floor 1 has a conventional structure. It consists of - an underlayer 4 formed of compacted stones / pebbles, having a minimum lift of 30 MPa, and - an overlayer 5 formed of compacted crushed gravels.

La surcouche de graves 5 présente avantageusement une épaisseur comprise entre 10 et 15 cm ; on utilise de préférence des graves fines et fermées, de type 0/14 à 0/20.The bass overlay 5 advantageously has a thickness of between 10 and 15 cm; preferably fine and closed gravel, type 0/14 to 0/20 is used.

Le compactage des deux couches 4 et 5 du fond de sol 1 s'effectue de manière classique au moyen d'un compacteur à pneus ou à billes.The compaction of the two layers 4 and 5 of the floor bottom 1 is carried out in a conventional manner by means of a roller compactor or ball.

Eventuellement, une couche d'émulsion bitumineuse formant couche d'imprégnation peut être déposée sur le fond de sol 1, associée ou non à de fins graviers, avant le dépôt des couches de granulats de caoutchouc 2, 3.Optionally, a bituminous emulsion layer forming an impregnation layer may be deposited on the bottom of soil 1, associated or not with fine gravel, before the deposition of the layers of rubber granules 2, 3.

Le caoutchouc utilisé pour former la couche de base 2 et la couche de surface 3 provient du recyclage de pneumatiques usagés.
On utilise des granulats de forme irrégulière, obtenus par broyage de la gomme des pneumatiques, après enlèvement de la structure métallique de renfort.The rubber used to form the base layer 2 and the surface layer 3 comes from the recycling of used tires.
Irregularly shaped aggregates obtained by grinding the rubber of the tires after removal of the reinforcing metal structure are used.

Les granulats de caoutchouc utilisés pour former la couche de base 2 ont, pour au moins 90 % en masse, une granulométrie comprise entre 2 et 12 mm, avantageusement encore comprise entre 4 et 8 mm, au regard de la norme française AFNOR XPT-47-752 (Les valeurs indiquées correspondent à la plus grande dimension des granulats).
Pour assurer la cohésion entre eux, ces granulats de caoutchouc sont mélangés avec un liant avant d'être mis en oeuvre sur le fond de sol 1.The granules of rubber used to form the base layer 2 have, for at least 90% by mass, a particle size of between 2 and 12 mm, advantageously still between 4 and 8 mm, with regard to the French standard AFNOR XPT-47 -752 (The values indicated correspond to the largest dimension of aggregates).
To ensure cohesion between them, these rubber granules are mixed with a binder before being used on the floor bottom 1.

Le liant utilisé est avantageusement une résine polymérisable, avantageusement de type polyuréthane mono composant exempt de solvant (par exemple une résine commercialisée sous la dénomination Conica 322 (Marque déposée)). Pour obtenir une cohésion satisfaisante et garantir les caractéristiques physiques, le poids de la résine utilisée est compris entre 12 et 25 % du poids du granulat.The binder used is advantageously a polymerizable resin, advantageously of the solvent-free mono-component polyurethane type (for example a resin sold under the name Conica 322 (registered trademark)). To obtain a satisfactory cohesion and to guarantee the physical characteristics, the weight of the resin used is between 12 and 25% of the weight of the granulate.

Le malaxage du granulat avec la résine est réalisé sur le site, dans un malaxeur classique.Mixing of the granulate with the resin is carried out on site, in a conventional mixer.

La mise en oeuvre du mélange obtenu sur le fond de sol 1 est réalisée par une machine de type finisseur permettant la réalisation de revêtements de faible épaisseur en assurant un très bon compactage. Le serrage est effectué par lames chauffantes en mouvements alternatifs.The use of the mixture obtained on the bottom of soil 1 is carried out by a machine of the type finisher allowing the realization of thin coatings by ensuring a very good compaction. The tightening is performed by heating blades in reciprocating movements.

On obtient une surface compactée de granulats liés, ayant une planimétrie régulière.A compacted surface of bound aggregates having a regular planimetry is obtained.

L'épaisseur finale de la couche de base 2 est avantageusement comprise entre 15 et 55 mm ; de préférence, cette épaisseur est comprise entre 25 et 40 mm, et encore de manière préférée voisine de 35 mm.The final thickness of the base layer 2 is advantageously between 15 and 55 mm; preferably, this thickness is between 25 and 40 mm, and more preferably close to 35 mm.

Avant la polymérisation complète de la résine, la surface supérieure 6 de la couche de base 2 est grattée ou griffée, de manière à lui procurer un état de surface « rugueux », non lisse.
Cette opération de grattage ou griffage est de type pluridirectionnel, c'est-à-dire qu'elle est réalisée selon au moins deux directions. Elle est mise en oeuvre manuellement, par exemple au râteau, ou au moyen de tout mécanisme approprié (par exemple intégré à la machine de mise en oeuvre du mélange granulats/liant).
Pour la majorité, ces striures ou griffures ont une profondeur maximale de 10 mm, de préférence comprise entre 5 et 10 mm.Before the complete polymerization of the resin, the upper surface 6 of the base layer 2 is scraped or scratched, so as to provide a "rough" surface condition, not smooth.
This scraping or scratching operation is of the pluridirectional type, that is to say that it is carried out according to at least two directions. It is implemented manually, for example by rake, or by means of any suitable mechanism (for example integrated in the machine for implementing the mixture granules / binder).
For the majority, these striations or scratches have a maximum depth of 10 mm, preferably between 5 and 10 mm.

Une fois la couche de base 2 stabilisée par la polymérisation complète de la résine, des granulats de caoutchouc libres sont étalés sur la surface rugueuse 6 de manière à constituer la couche de surface 3. Les granulats de caoutchouc utilisés pour former cette couche de surface 3 ont, pour au moins 90 % en masse, une granulométrie comprise entre 1 et 10 mm, avantageusement encore comprise entre 1 et 8 mm, selon la norme AFNOR précitée, (les valeurs indiquées correspondent à la plus grande dimension des granulats).Once the base layer 2 is stabilized by the complete polymerization of the resin, free rubber granules are spread on the rough surface 6 so as to constitute the surface layer 3. The rubber granules used to form this surface layer 3 have, for at least 90% by mass, a particle size of between 1 and 10 mm, advantageously still between 1 and 8 mm, according to the abovementioned AFNOR standard (the values indicated correspond to the largest dimension of the granules).

L'épaisseur moyenne de cette couche de surface 3 est avantageusement comprise entre 10 et 100 mm ; de préférence, cette épaisseur est comprise entre 20 et 40 mm, et encore de manière préférée voisine de 30-35 mm.The average thickness of this surface layer 3 is advantageously between 10 and 100 mm; preferably, this thickness is between 20 and 40 mm, and more preferably close to 30-35 mm.

La structure de sol ainsi préparée convient très bien au déplacement des chevaux ou poneys.The soil structure thus prepared is very suitable for moving horses or ponies.

La couche stable de caoutchouc (couche de base 2) et la couche « mobile » de caoutchouc (couche de surface 3) confèrent à ce sol de très bonnes qualités d'amortissement. En outre, le sol obtenu présente des caractéristiques d'enfoncement et de déformation satisfaisantes (sol pas trop « fouillant »).The stable layer of rubber (base layer 2) and the "mobile" layer of rubber (surface layer 3) give this soil very good damping qualities. In addition, the resulting soil has satisfactory sinking and deformation characteristics (soil not too "digging").

L'état de surface « rugueux » de la couche de base 2 permet de tenir convenablement le granulat de surface libre. Cette couche de base 2 permet l'obtention d'un sol ayant une bonne cohésion horizontale (effet « grip ») pour éviter le glissement horizontal trop important des chevaux. D'autre part, la couche supérieure « mobile » confère tout de même aux animaux une certaine souplesse de marche ou de course, autorisant la mobilité nécessaire au sabot lors de l'impact (léger glissement dans toutes les directions). La structure de sol conforme à l'invention s'avère très confortable et sûre.
Elle convient très bien, non seulement pour les manèges et les carrières, mais aussi pour la réalisation de surfaces de paddocks et de pistes couvertes ou extérieures (pistes de dressage, de sauts d'obstacles...). Elle apporte en outre des caractéristiques favorables à la santé articulaire des chevaux et à la sécurité des cavaliers.The "rough" surface condition of the base layer 2 makes it possible to adequately hold the free surface granulate. This base layer 2 makes it possible to obtain a floor having good horizontal cohesion ("grip" effect) in order to prevent excessive horizontal sliding of the horses. On the other hand, the "mobile" top layer still gives the animals a certain flexibility of walking or running, allowing the mobility necessary for the hoof during the impact (slight sliding in all directions). The floor structure according to the invention is very comfortable and safe.
It is very suitable not only for rides and quarries, but also for the realization of paddock surfaces and covered or outdoor tracks (training courses, jumping obstacles ...). It also provides favorable characteristics for the joint health of horses and the safety of riders.

  8. The equestrian floor according to any one of claims 1 to 7, characterized in that the sub-soil (1) is comprised of:
    - a compacted metalled sub-layer (4), with a minimum bearing capacity of 30 MPa, and
    - a compacted over-layer (5), comprised of gravels of the 0/10 to 0/20 type, the thickness of which is between 10 and 15 cm.
  9. A method of making an equestrian floor according to any one of claims 1 to 8, characterized in that it comprises:
    - making a compacted rock- and/or gravel-based, consolidated sub-soil (1),
    - making a mix of rubber granulates and a binder of the polymerizable resin type,
    - compacting said granulates/resin mix on said sub-soil (1), to obtain the base layer (2),
    - making a multidirectional streaking on the top surface (6) of said base layer (2), to obtain roughening streaks, before the full polymerization of the resin, and
    - after polymerization of the resin, adding free rubber granulates on said base layer (2), to form the surface layer (3).
