    Technical field to which the invention relates
    The present invention relates, in general, to the field of floor coverings, in particular for the floor of an enclosure for the breeding of animals (for example cattle).
    It relates in particular to floor coverings suitable for the development of circulation corridors of such a breeding enclosure.
    Technological background
    The comfort of the animals constitutes a determining parameter in the yield of a breeding, which influences in particular the health, the food intake, the fertility and the longevity of the animals.
    This animal comfort is governed in particular by legal obligations which are defined in the Treaties of Amsterdam (1999) and Lisbon (2009) relating to the Protocol on the protection and welfare of animals, as well as by the adoption of the second European strategy for animal welfare.
    In a stable, this comfort implies in particular a rapid and efficient evacuation of the excrement generated by the animals.
    This management of droppings must in fact make it possible to reduce gas emissions and the proliferation of bacteria in the breeding grounds, and consequently to improve the ambient conditions and sanitary performance.
    These droppings are more likely to make the floor slippery, with the risk of falling and injury that result.
    Several manure evacuation systems coexist to date: mechanical evacuation systems, "water flush" systems and gratings systems.
    As part of a "mechanical evacuation" solution, the droppings on the ground are scraped one to several times a day by a scraping device called a planer (operated by a tractor or by automatic means), to be brought to a collection pit located outside the livestock building.
    However, the separation of urine and faeces is not optimal in such an evacuation system, thus constituting an important source of ammonia. In addition, the installation of such an evacuation system involves major structural work, which is difficult to envisage in an existing livestock enclosure.
    With a "flush", a flushing liquid vigorously evacuates the excreta in a gutter and then towards an external pit.
    However, here again, the separation of urine and faeces is not optimal within such an evacuation system, still constituting an important source of ammonia. In addition, the implementation of such a system leads to significant humidification of the floors of the livestock enclosure, likely to generate adhesion and hygiene problems.
    More generally, an excessively wet floor covering is likely to cause health problems at the level of the feet of the animals, in particular of lameness, constituting a major health problem in breeding.
    Among the infections causing lameness, digital dermatitis, also called "Mortellaro disease", is the most problematic.
    There is therefore a need for technical solutions allowing a reduction in the humidity of the bearing surfaces on the floor of the breeding enclosures with an effective evacuation of liquids (in particular urine), advantageously this without requiring major work. important work, so as to improve the grip conditions and the sanitary conditions of the animals.
    There is also an interest in simple solutions which possibly allow a certain separation of urine and faeces, so as to limit the production of ammonia in the breeding grounds.
    Object of the invention
    In this context, the plaintiff has developed a new structure for floor covering aimed at improving the hygienic conditions in a breeding enclosure, in particular by optimal management of liquids.
    The flooring according to the invention comprises for this purpose beams which are made of at least one elastic material and which are intended to be juxtaposed to form a support surface.
    The longitudinal members each have a set of faces:
    - two front faces, one intended to rest on a receiving surface and the other intended to form a support portion of said support surface, and
    - two lateral faces, at least one of which is intended to come opposite the lateral face of a juxtaposed spar.
    According to the invention, the side members have housings adapted to cooperate with spacers which are attached to stabilize the side members juxtaposed in a fixed spacing.
    The spacers each include:
    - fixing parts, adapted to be housed in said housings of two juxtaposed beams, and
    - a connecting part, connecting the fixing parts.
    And the fixing parts of said spacers and the housings of two juxtaposed spars are arranged to preserve a space, advantageously a groove opening upwards, between the lateral faces of the juxtaposed spars.
    Preferably, for this purpose, the spacing of said fixing parts is greater than the spacing of the housings of two adjoining side rails, to preserve a space, advantageously a groove opening upwards, between the lateral faces of the juxtaposed side rails.
    The floor covering according to the invention, intended to equip an enclosure for the breeding of animals, is adapted to form a support surface on which the animals are intended to rest; and this bearing surface is intended to be divided into a plurality of bearing portions (each formed by a spar) which are separated from each other by grooves (space between two juxtaposed spars) intended to receive the liquids flowing over said coating.
    Such a structure allows automatic and continuous evacuation of liquids from said support portions, to said grooves.
    The bearing surfaces of the floor covering therefore remain permanently relatively low in moisture, thereby helping to improve the qualitative characteristics of the soil in terms of adhesion and hygiene.
    This structure also allows rapid and relatively effective separation of urine from faeces, to limit the production of ammonia within the breeding enclosure.
    Such a floor covering according to the invention is further adapted to be installed in a simple manner within a new or existing breeding enclosure (improvement or renovation), this without requiring the implementation of major structural work. .
    The less humid environment also allows the hoof of the cattle to be harder, which is part of the health of the feet of these animals and which contributes to decrease the risks of slips of the animals.
    According to a preferred embodiment, the housings are formed on at least a first of said front faces of said beams, and each extend along said lateral faces of said beams.
    Non-limiting and advantageous characteristics of this embodiment, taken individually or in any technically possible combination, are the following:
    - at least one of the side members comprises at least two longitudinal grooves forming said housings; the longitudinal grooves advantageously have the following dimensions: a width of between 2 and 10 mm, and a depth of between 8 and 28 mm;
    - Said at least one spar comprises at least one lateral lip which, on the one hand, delimits said at least one groove and, on the other hand, forms the lateral face of said spar; which lateral lip has a free edge offset relative to said first front face, on the side of the second front face, for example by a distance of between 1 mm and 5 mm; which lateral lip has for example a thickness of between 5 and 20 mm.
    According to yet another particular embodiment, the spacers consist of profiles which are made for example of plastic material.
    The profiles advantageously have a U-shaped section, with:
    - two external flaps forming the fixing parts, advantageously provided with hooking ribs, and
    - a bottom flap forming the connecting part.
    At least one of the profiles advantageously comprises two interior shutters, at a distance from each other and from the exterior shutters; which interior flaps are advantageously intended to each take support on a side face of an associated spar.
    The interior shutters are advantageously connected by a transverse shutter, facing and at a distance from the bottom shutter. This transverse flap is advantageously continuous, or discontinuous to form at least one lumen.
    In general, the side members advantageously have the following dimensions:
    - a width between 150 and 400 mm, and
    - a height between 15 and 40 mm.
    The invention also provides a system for collecting the manure flowing on the floor of an enclosure for breeding animals, for example cattle, which system comprises:
    - a floor covering according to the invention, and
    - Means for conveying the droppings within said grooves, so as to generate a circulation of said droppings along said grooves and in the direction of collection means.
    The invention also provides a breeding enclosure equipped with a floor covering according to the invention, or even a system for collecting excrement according to the invention.
    The breeding enclosure advantageously comprises a circulation corridor having a longitudinal axis and covered by a floor covering. The rails of said floor covering are arranged parallel, or at least approximately parallel, with respect to said longitudinal axis.
    The side members are placed with the first of said front faces resting on the receiving surface, so that the side members are attached to the spacers.
    The present invention also relates to the spar for a floor covering, in particular for the floor of an enclosure for the breeding of animals (for example cattle).
    Said beam is made of at least one elastic material and intended to be juxtaposed with another beam to form a support surface.
    This spar has a set of faces:
    - two front faces, one intended to rest on a receiving surface and the other intended to form a support portion of said support surface, and
    - two lateral faces, at least one of which is intended to come opposite the lateral face of a juxtaposed spar.
    Which spar has housings adapted to cooperate with spacers which are attached to stabilize the spars juxtaposed in a fixed spacing.

    Flooring
    The floor covering 1 according to the invention, shown diagrammatically and partially in FIG. 1, is very particularly suitable for equipping the ground with an enclosure E for the breeding of animals.
    By "animals" is meant in particular cattle (in particular dairy cows or beef cattle), pigs, or any other farm animal (sheep, poultry, rabbit, horse, etc.).
    Such a breeding enclosure (not shown) consists of a building delimited by a frame, suitable for the desired breeding (for example a barn in the case of cattle).
    At least part of the soil of this breeding enclosure E is covered by the floor covering 1 according to the invention.
    In particular, the floor covering 1 is advantageously located at the level of the circulation corridors Ç which are used by the animals traveling between the different functional spaces of the breeding enclosure E (for example cubicles, milking parlors, etc.) .
    And this floor covering 1 is able to collect the liquids flowing on the ground and to evacuate them, so as to offer a relatively dry bearing surface (or at least not having excessive humidity) for the feet of the animals. , and therefore healthier.
    For this, as illustrated in FIG. 1, this floor covering 1 comprises a support surface 2 on which the animals are intended to bear and which is divided into a plurality of separate support portions 21, each others, by grooves 3.
    The support portions 21 of the support surface 2 extend between two grooves 3, and advantageously in the same plane, or at least approximately in the same plane.
    The space between two support portions 21 forms one of these grooves 3 opening upwards.
    The grooves 3 thus constitute structures of the gutter or gutter type opening upwards, through the support surface 2.
    These grooves 3 are capable of collecting (by gravity), or even containing, the liquids flowing on the floor covering 1, so that these liquids stagnate as little as possible on the support portions 21.
    By "liquids" is meant in particular the liquid faeces produced by farm animals, in particular their urine.
    In general, as described below in relation to FIGS. 2 and 3, each groove 3 is delimited by two lateral faces 31 connected by a bottom face 32.
    These grooves 3 advantageously have particular dimensions to allow efficient collection of liquids, while avoiding being a hindrance for the movement of animals.
    In this regard, as illustrated in FIG. 3, each groove 3 can be defined by two dimensions: a width A (distance separating its two lateral faces 31 facing each other) and a depth P (maximum distance separating its bottom face 32 and the adjoining support portions 21).
    In this case, the grooves 3 advantageously each have:
    - a width A of at most 50 mm, preferably between 15 and 50 mm, and
    - A depth P of at least 15 mm, advantageously between 15 and 50 mm.
    The grooves 3 are advantageously regularly spaced, relative to one another, on the floor covering 1.
    In other words, these grooves 3 are advantageously regularly distributed over the floor covering 1.
    For this, the floor covering 1 here includes:
    - longitudinal members 5, intended to be juxtaposed to form the support portions 21 of the support surface 2, and
    - spacers 6 added to stabilize the side members 5 juxtaposed in a fixed spacing / spacing (with a determined space), so as to define the grooves 3 between the side members 5 juxtaposed (in other words, the side members 5 are not attached or not adjoining ).
    rails
    The beams 5 may consist of beams, as shown in Figures 1 to 6. Alternatively, these beams 5 may also consist of parts in the form of a carpet.
    The longitudinal members 5 are made of at least one elastic material, advantageously adapted to undergo a deformation in driving in, that of at least 1 mm, and preferably between 1 and 5 mm, when the foot of the animal is pressed. or a person.
    By "sinking" is meant in particular a reduction in the thickness of the beam 5.
    For this, said at least one material capable of undergoing elastic deformation is chosen from:
    - elastomeric materials, for example natural rubber, “synthetic natural” rubber (or synthetic polyisoprene), polybutadiene or styrene-butadiene, or
    - plastics or thermoplastic elastomers (TPE), namely for example PVB (Polyvinyl butyral), ABS (acrylonitrile butadiene styrene) / SBR (styrene-butadiene), PP (polypropylene) / EPDM (ethylenepropylene-diene monomer), TPU (polyurethane TPE).
    These beams can be made of single-material or multi-material.
    More specifically, these beams 5 advantageously have a generally parallelepiped shape. They thus each comprise a set of longitudinal faces (Figures 1 and 2):
    - two front faces 51,52, one lower and the other upper,
    - two lateral faces 53, longitudinal, advantageously parallel to one another, and
    - two end faces 54, transverse, advantageously parallel to one another.
    The front faces 51, 52 advantageously consist of:
    a first, lower front face 51, intended to rest on a receiving surface (for example a concrete screed or a grating), and
    - A second upper front face 52, intended to form one of the support portions 21 of the support surface 2.
    The second upper face 52, preferably, consists of a horizontal plane surface or a convex curved surface.
    For optimal grip, the second front face 52 is advantageously provided with non-slip reliefs.
    The non-slip relief consists, for example, of a one-piece relief chosen from the reliefs used in floor coverings conventionally used in livestock buildings, for example diamond-shaped projecting elements provided with bosses.
    The second front face 52 also advantageously comprises a layer of an abrasive material, in order to allow and / or promote the wear of the hooves and the health of the feet of the animals.
    To obtain this layer of abrasive material, the abrasive material is advantageously mixed with the material constituting the spar 5.
    The abrasive material consists for example of particles of quartz, metal or any other material having an abrasive power on the cows' hoof.
    This abrasive material is added before, during or after the manufacture of the beam 5.
    The lateral faces 53, vertical, are intended to come opposite the lateral face 53 of a juxtaposed spar 5.
    The longitudinal members 5 advantageously have the following dimensions:
    a width (distance between the lateral faces 53) of between 100 and 500 mm, preferably between 150 and 400 mm, and
    - A height (distance between the front faces 51, 52) of between 15 and 40 mm.
    According to the invention, the side members 5 have housings 55 adapted to cooperate with the spacers 6 which are attached to stabilize the side members 5 juxtaposed in a fixed spacing.
    The housings 55 are formed here on the first end face 51 of the longitudinal members 5. These housings 55 thus open on the side of this first end face 51.
    These housings 55 advantageously extend each along (close to) the lateral faces 53 of the longitudinal members 5.
    In this case, each spar 5 comprises at least two longitudinal grooves 55 forming said housings, each extending along one of its two lateral faces 53.
    In other words, each lateral face 53 of the spar 5 is bordered by at least one longitudinal groove 55 (a continuous longitudinal groove or a discontinuous longitudinal groove) forming a housing.
    The longitudinal grooves 55 advantageously have the following dimensions (FIG. 3):
    - a width L of between 2 and 10 mm (distance measured parallel to the front faces 51.52), and
    - a depth G of between 8 and 28 mm (distance measured parallel to the lateral faces 53).
    This spar 5 here comprises two lateral lips 56 which, on the one hand, delimits a groove 55 mentioned above and, on the other hand, forms one of the lateral faces 53 of this spar 5.
    For this, this lateral lip 56 has the following faces:
    an inner lateral face 561, delimiting the groove 55,
    an outer lateral face 562, forming one of the lateral faces 53 of the spar 5, and
    - a free border 563, extending from the side of the first front face 51 (lower).
    The thickness of the lateral lip 56 corresponds to the distance between its two lateral faces 561, 562. This thickness is for example between 5 and 20 mm.
    The free edge 563 is offset relative to the first front face 51 (lower), that on the side of the second front face 52 (upper). This offset is useful for taking into account the positioning and size of the spacers 6.
    The offset of this free border 563, relative to the first front face 51 (lower), is for example between 1 mm and 15 mm.
    In general, the side members 5, before their installation, can advantageously be stored flat or in the form of rolls.
    This latter embodiment in rolls has the advantage of allowing a simple and rapid installation of the side members 5 in the breeding enclosure by unwinding; it also ensures optimum continuity of the grooves 3 for efficient recovery of liquids at the ends of the latter.
    spacers
    The floor covering 1 also includes the spacers 6, described in detail below in relation to FIG. 3.
    Each spacer 6 includes:
    fastening parts 61, adapted to be housed in the housings 55 of two side members 5 juxtaposed, and
    - a connecting part 62, connecting these fixing parts 61.
    The fixing parts 61 are spaced apart by a spacing E which is defined here by the connecting part 62.
    The fastening parts 61 of the spacers 6 and the housings 55 of two juxtaposed longitudinal members 5 are arranged to preserve a space 3, advantageously a groove 3 opening upwards, between the lateral faces 53 of the juxtaposed longitudinal members 5.
    To this end, the spacing E of the fastening parts 61 is advantageously greater than the spacing of the housings 55 of two adjoining side rails 5 (configuration not shown), to preserve a space / spacing (forming a groove 3) between the faces side 53 of the side members 5 juxtaposed.
    By "side rails 5 joined" is meant two side rails 5 whose side faces 53 facing each other are in abutment (also said to be in contact) one on the other.
    The "intermediate" space, held between the lateral faces 53 of two juxtaposed longitudinal members 5, forms a groove 3 intended to receive the liquids flowing on the bearing surface 2.
    In this case, the spacers 6 here consist of profiles (designated by the same reference 6) which are made for example of plastic material.
    The spacers 6 are for example made of a material chosen from acrylonitrile butadiene styrene (ABS), polyethylene (PE), polyamide (PA), polypropylene (PP), polyvinyl chloride (PVC) or any other mixed plastic material (including recycled plastic materials).
    In general, the profiles 6 have a U-shaped section, with:
    - two external flaps 61 (vertical), forming the fixing parts 61, and
    - a bottom flap 62 (horizontal), forming the connecting part 62 and here forming a bottom face of a groove 3.
    The outer flaps 61 advantageously extend, on the one hand, parallel to one another and, on the other hand, at right angles to the bottom flap 62.
    The external flaps 61 are advantageously provided with attachment ribs 611, to promote the attachment of these external flaps 61 within the housings 55.
    These hooking ribs 611 are oriented to promote penetration while increasing the separation / extraction force.
    The profile 6 here again comprises two interior flaps 63 which are advantageously intended to each bear on a lateral face 53 of an associated spar 5.
    The two inner flaps 63 form, with the adjoining side faces 53, the two side faces 31 of a groove 3.
    The two interior flaps 63 extend from the bottom flap 62, between the two exterior flaps 61.
    The internal shutters 63 extend at a distance from each other and from the external shutters 61.
    These internal shutters 63 still advantageously extend, on the one hand, parallel to one another and with respect to the external shutters 61, and on the other hand, to the square with respect to the bottom shutter 62 .
    The interior flaps 63 and the central strip 621 of the bottom flap 62 (between the two interior flaps 63) are advantageously continuous. These flaps 62, 63 thus advantageously form a liquid-tight structure, capable of serving as a channel for collecting and routing the liquids.
    Furthermore, the spacing between the two interior flaps 63 advantageously corresponds, at least approximately, to the width A of the groove 3.
    Similarly, an interior flap 63 and the exterior flap 61 opposite form, with a side strip 622 of the bottom flap 62, a U-shaped groove opening opposite the bottom flap 62 to receive (apart from play) a lateral lip 56 mentioned above.
    To ensure improved sealing and maintenance, the spacing between an inner flap 63 and the outer flap 61 opposite advantageously corresponds to the thickness of the abovementioned lateral lip 56 (distance between its two lateral faces 561,562).
    Still further, the internal flaps 63 advantageously have a greater height than the external flaps 61.
    In this regard, the external flaps 61 have for example a height less than, or equal to, the depth of the longitudinal grooves 55. The internal flaps 63 have a height that is less than, or equal to, the height of the side members 5; in particular, the internal flaps 63 advantageously have a height ranging from a minimum height corresponding to half the height of the side members 5, up to a maximum height corresponding to the height of the side members 5.
    In addition, as illustrated in FIGS. 1 to 3, the interior flaps 63 can carry a transverse flap 64, facing and at a distance from the bottom flap 62 (and in particular from its central strip 621).
    In this case, this transverse flap 64 is located between the bottom flap 62 and the free end 631 of the interior flaps 63 (Figure 3).
    The profile 6 thus comprises a longitudinal chamber delimited by the central strip 621 of the bottom wall 62, by the two interior flaps 63 and by the transverse flap 64.
    The transverse flap 64 may be discontinuous, to form at least one lumen 65, through and elongated.
    The transverse flap 64 can thus comprise a continuous light or a discontinuous light (several successive lights).
    Such an embodiment is interesting for optimizing the separation of waste:
    - any solid waste will remain above this transverse component 64, and
    the liquid waste will pass through said at least one lumen 65, so as to come between the transverse flap 64 and the bottom flap 62.
    Alternatively, as illustrated in FIG. 4, the profile 6 comprises the external flaps 61 and the internal flaps 63 which are carried by the bottom flap 62.
    This profile 6 is however devoid of the transverse flap 64. The internal flaps 63 thus form, with a central strip 621 of the bottom flap 62, a groove corresponding to the groove 3 intended to receive the liquids.
    According to an alternative embodiment illustrated in FIGS. 5 and 6, the internal flaps 63 carry by a transverse flap 64, facing and at a distance from the bottom flap 62.
    The internal flaps 63 advantageously have a height equal to the height of the side members 5.
    The transverse flap 64 is continuous. It advantageously extends in the plane, or at least approximately in the plane, of an opposite front face 51, 52.
    Again alternatively, the profile 6 only comprises the bottom flap 62 carrying the external flaps 61 (without the internal flaps 63).
    Collection system
    According to an embodiment represented in FIGS. 1 to 3, the floor covering 1 can equip a system for collecting the manure flowing on the floor of an enclosure for the breeding of animals.
    In this context, this system advantageously comprises:
    - a floor covering 1 according to the invention (as described in FIGS. 1 to 4), and
    - Means 7 for conveying the droppings within the grooves 3, so as to generate a circulation of the droppings along said grooves 3 and in the direction of collection means (not shown).
    The collection means comprise in particular a pit (or a recovery channel), installed at at least one open end of the grooves 3 of the floor covering 1.
    These collection means may also include conduits for the evacuation of liquids.
    The conduits open, on an upstream side, in the grooves 3 and, on a downstream side, opposite the orifices of a grating.
    In order to generate an optimal circulation of liquid manure towards these collection means (and possibly solid manure), the collection system according to the invention also comprises the means 7 for conveying the liquids (and possibly solid manure) on along the grooves 3 of the floor covering 1.
    In this case, these conveying means 7 for this include drive members 71 which are attached in the grooves 3 and which are coupled with operating means 72 (Figure 1) to apply a movement intended to cause displacement droppings in a suitable direction within these grooves 3.
    The drive members 71 advantageously consist of endless bands or belts which are attached in and along the grooves 3 and the profiles 6.
    These drive members 71 are shown partially and schematically in Figures 1 to 3 for the sake of simplification. However, in practice, these drive members 71 are advantageously intended to extend over the entire length of the associated profiles 6.
    These drive members 71 advantageously comprise conveying surfaces forming kinds of planes or scrapers, capable of pushing / repelling / pulling the droppings present within the associated profiles 6.
    Preferably, these drive members 71 are made in one piece, in an elastomeric material, namely for example natural rubber, “synthetic natural” rubber (or synthetic polyisoprene), polybutadiene or styrene-butadiene.
    This material of the drive members 71 participates in limiting the friction with the profiles 6.
    The maneuvering means 72 ensure an operation in translation of the drive members 71 within their respective profiles 6, so as to generate a circulation of the droppings within these associated profiles 6.
    During this translational maneuver, the friction forces are advantageously reduced in particular due to the properties of the profiles 6.
    For example, the operating means 72 advantageously comprise a set of pulleys cooperating with the drive members 71.
    According to an embodiment shown in Figures 1 to 3, the pulleys 72 are arranged so that the drive members 71 form a back-up within a single groove 3 and its associated profile 6.
    In this embodiment, the drive member 71 advantageously comprises two active strands superimposed in the profile 6 (FIG. 3):
    - an upper strand 711 traveling above the transverse flap 64, forming an upper part capable of serving as a support for solid excrement while allowing the flow of liquid excrement, and
    - A lower strand 712 traveling below the transverse flap 64, forming a lower part capable of conveying the liquid excrements flowing from said upper part 711.
    Such an embodiment aims to promote an evacuation, on the one hand, of solid droppings at a first end of the groove 3 and, on the other hand, of liquid droppings at the level of a second end of the groove 3.
    According to another embodiment, the pulleys 72 are arranged so that the drive members 71 form a back-and-forth assembly within the successive sections 6, to present a general shape of S (top view).
    In the various embodiments, at least one of the pulleys 72 is motorized to ensure the routing of the drive members 71.
    The tracking speed is for example between 1 and 10 m / min, in particular according to the concentration of animals per m 2 and the type of dejection.
    Two successive active strands 71 thus travel in opposite directions relative to one another.
    Breeding enclosure
    In practice, as shown in Figures 1 to 5, the side members 5 are placed with the first end face 51 resting on the receiving surface.
    The longitudinal members 5 are attached to the spacers 6 which are also placed on the side of the receiving surface.
    In particular, the fixing parts 61 of the spacers 6 are housed by fitting into the dedicated housings 55 of the longitudinal members 5. If necessary, the bottom flap 62 of the profiles 6 bears on the ground, in the extension of the first end faces 51 stringers 5.
    In general, the side members 5 and the spacers 6 of the profile type are advantageously placed in staggered rows: the profiles 6 connect the side members 5 placed in series, edge to edge.
    The longitudinal members 5 are then stabilized by the spacers 6, so that the grooves 3 open upwards to receive the liquids by gravity.
    These grooves 3 are advantageously rectilinear and extend parallel to each other.
    Each groove 3 thus has a longitudinal axis 3 ’, extending parallel to its lateral faces 31; the longitudinal axes 3 ’of the different grooves 3 extend parallel to each other.
    Preferably, the grooves 3 are distributed over the width of the floor covering 1; and these grooves 3 extend over the entire length of the floor covering
    1.
    The grooves 3 thus delimit between them a plurality of support portions 21 which each have the shape of a rectilinear strip.
    Each spar 5 has a longitudinal axis 5 ', extending parallel to the longitudinal axis 3' of the grooves 3 and to the longitudinal axis 5 'of the other spars 5.
    More preferably, the breeding enclosure E comprises a circulation corridor Ç having a longitudinal axis C ’and covered by the floor covering 1.
    And the side members 5 of this floor covering 1 are arranged parallel, or at least approximately parallel, with respect to this longitudinal axis C ’of the circulation corridor Ç.
    This orientation is in particular useful for promoting the evacuation of the liquids contained in the grooves 3 to the collection means equipping the breeding enclosure and which are located at the end of the circulation corridors Ç.
    In operation, the floor covering 1 is capable of receiving different organic materials, in particular droppings (urine, faeces).
    The floor covering 1 then allows a flow of liquids between the side rails 5, up to the grooves 3, thus avoiding the accumulation of these liquids on the side rails 5 which thus remain relatively dry.
    The solid materials, in particular the faeces, remain mainly on the side rails 5, so as to avoid their mixing and to limit the production of ammonia within the breeding enclosure.
    These solid materials are advantageously removed by scraping the side members 5, by means of a scraping system optionally chosen from the usual systems.
    When cleaning this floor covering 1, the cleaning liquid will also flow into these grooves 3, preventing the side rails 5 from remaining excessively wet.
    This phenomenon therefore allows animals to walk on a relatively healthy support surface 2, with a reduced risk of falling and without wetting their feet.
    In general, the floor covering 1 according to the invention thus allows rapid and continuous evacuation of the liquids relative to the support surface 2, which allows effective maintenance of the latter in the dry state (or at less without excess moisture), thus limiting the hygiene problems encountered with conventional floor coverings.
    The floor covering 1 according to the invention also allows a certain separation of the liquids which flow in the grooves 3, with respect to the faeces which remain mainly on side rails 5, so as to avoid their mixing and to limit the production of ammonia. within the breeding grounds.
    According to an alternative embodiment illustrated in Figure 5, the floor covering 1 comprises a profile 6 which is provided with a continuous transverse flap 64.
    This transverse flap 64 advantageously extends in the plane, or at least approximately in the plane, of the second front face 52.
    The floor covering 1 will then have a continuous support surface 2.
    According to a variant of installation illustrated in FIG. 6, the first front face 51 provided with the housings 55 is oriented upwards.
    The spacers 6 are then attached to the side members 5, so that their bottom flaps 62 form part of the support surface 2 between two side members 5.
    The transverse flap 64 advantageously extends in the plane, or at least approximately in the plane, of the second front face 52 (here lower).
    Again, the flooring 1 will have a continuous support surface 2.
    Again according to a variant not shown, the spacers 6 are chosen with a spacing E of the fixing parts 61 which is identical to the spacing of the housings 55 of two longitudinal members 5 whose side faces 53 are joined.
    The floor covering 1 would then comprise side rails 5 which are joined (the lateral faces 53 bearing one on the other) to form a continuous support surface 2.
