Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to the field of surface coverings, in particular to floor covering fixing devices, in particular to damping floors such as playground floors. In particular a system for fixing the periphery of such coatings.

The present invention also relates to a method for repairing the peripheries of a coating of a support surface.

STATE OF THE PRIOR ART

The problem of detachment of coverings and damping floors at their periphery is known. In fact, the edges of damping floors, for example damping floors of play areas, have greater fragility and a tendency to peel off or tear off following repeated trampling by users; temperature variations; the stagnation of rainwater due to the irregularity of the levels of the supports; mechanical sweepers in schoolyards etc.

Furthermore, the floor coverings can be used for various recreational and sporting applications, such as athletics tracks, playgrounds, horse riding, and also in road works and various networks, for the repair of cavities. on asphalt pavements, called potholes, for example. In these cases, the operating methods are adapted according to the field of intervention.

There are various solutions for fixing floor coverings, and in particular for fixing shock-absorbing floors.

A first solution is to glue the damping coating directly to the ground acting as a support, the ground generally being asphalt or concrete. This requires large quantities of glue and the periphery of these floors remains fragile and sensitive to detachment, for the reasons mentioned above.

Another solution is to make a sill, also called a trench, which consists of making a trench, or open tunnel, approximately 10 cm by 10 cm wide by 10 cm deep over the entire contour of the support on which the coating must be laid. A larger quantity of aggregates is used in this solution, but the edges remain sensitive to tearing. Said coating is poured and/or deposited on the support and in the stringers in order to have a greater resistance to tearing at the level of these edges because it benefits from a greater thickness in these areas. However, this has the disadvantage of damaging the support located under the coating, because hollow stringers are necessary, and are made directly in the support. In addition, if the coating is removed or modified, it will also be necessary to restore and/or regroove the support before it can be used again. Thus the restoration of the support remains the responsibility of the operator, this representing a very significant cost.

Another solution consists in making a concrete slab about 10 to 15cm thick over the entire surface to be covered and on the periphery a foundation for the concrete curbs 20 cm high, 8 cm wide and thick. at least 1 m long. Thus, the level of said slab is controlled, which simplifies good drainage of rainwater. In addition, the upper parts of these borders are rounded and have a roughness which makes it possible to improve the adhesion of the coating with the border, when said coating is poured. However, this solution has the disadvantage of the necessary production of a specific support made for this purpose, which requires a considerable investment of time and money. If the installation is repaired, the operator must pay for the repair of the initial support or its replacement.

Another existing solution consists of the use of rubber borders. These curbs are made, like those in concrete, directly on a concrete base. However, this solution also requires a significant financial investment, as well as a significant time for completion.

All these costly solutions pose problems of durability, high maintenance costs, as well as environmental problems. In terms of durability, managers are generally forced to intervene 6 to 8 years after installation of the coating to bring it into conformity due to the detachment of the peripheries of the coating, which generates a significant cost, and problems of safety for equipment users. In environmental terms, the production and installation of such coatings produces a lot of waste, especially during the restoration intervention, the damping floors on the edge being cut and put in the dump, and during the significant use of glue. for the adhesion layer on the periphery so that the edges can hold as long as possible. The construction and repair of supports also have high financial and environmental costs.

Indeed, faced with the phenomenon of detachment of the peripheries, or borders, the restoration can be carried out in two different ways. A first possibility consists in cutting and removing the periphery of the coating at the level of the detachment, in order to replace it, which generates waste, then in making a new periphery, generally of another color, which represents a significant cost. The second possibility consists in making extra thicknesses of coatings at the level of the periphery, which gives rise to semi-bulged zones, likely to represent obstacles for the users, who can for example stumble over them. This type of solution generally does not meet the requirements of the standards in force because of security problems for users.

The documents US2011142539A1 and US2008248887A1 present examples of support coating devices and methods.

DISCLOSURE OF THE INVENTION

The object of the present invention is therefore to provide a floor covering device, making it possible to overcome at least some of the drawbacks of the prior art while providing an inexpensive, invisible and easy to install solution, reducing the quantities of waste and chemical products used in particular for fixing the coating, while being suitable for a large diversity of substrates, without the need to modify them, and this throughout the life of the damping floor.

DETAILED DESCRIPTION OF THE INVENTION

Many combinations can be envisaged without departing from the scope of the invention; the person skilled in the art will choose one or the other depending on the economic, ergonomic, dimensional or other constraints that he will have to respect.

By "spitage" we mean the fact of spiter, or even of gun-seal, that is to say for example the use of a gas gun and / or battery capable of driving nails into the 4 steel, concrete and other hard substrates.

By "chemical anchor" is meant the deposition of a bi-material resin, the reaction of which will cause the said resin to solidify and the latter to be fixed to the support 4.

By "net" is meant any grid, set of meshes which may have a round, square, diamond or even rectangular shape configured to allow a distribution of the adhesion forces and the pressures undergone during the use of the coating 5, once the net has taken hold by a layer of soil.

By coating 5 or "shock-absorbing" floor, is meant a floor whose properties make it possible to reduce the impact of a fall, for example in the context of playgrounds, where the users, most often children, are likely to fall frequently.

• un revêtement 5, préférentiellement amortissant, configuré pour recouvrir ledit support 4
• un dispositif de fixation 1 du revêtement 5 sur le support 4, le dispositif de fixation 1 comprenant au moins un premier élément de fixation 2 configuré pour être fixé directement sur une surface dudit support 4 par des moyens d'ancrage configurés en fonction de la nature du support 4.

In general, the present invention comprises a device 5 for coating a surface of a support 4, said device comprising:

• a coating 5, preferably damping, configured to cover said support 4
• a device 1 for fixing the covering 5 on the support 4, the fixing device 1 comprising at least a first fixing element 2 configured to be fixed directly on a surface of the said support 4 by anchoring means configured according to the nature of bracket 4.

Advantageously, the covering 5 is then fixed to the support 4 without the latter needing to be hollowed out and modified.

According to the invention, the fixing device 1 is completely embedded in said coating 5.

This allows the fixing system not to be visible while allowing excellent fixing with the coating 5 and with the support, capable of lasting over time 4. The fixing system is thus invisible to the user. Preferably, it does not significantly modify the damping capacities of the ground, given that this system is installed on the periphery, and therefore outside the impact zone, or potential fall zone, defined during the design of the zone to be cover with the coating.

In some embodiments, the first fixing element 2 forms a border delimiting at least part of the surface of the support 4 to be covered. In preferred non-limiting embodiments, the first fixing element 2 forms a border delimiting the entire surface of the support 4 to be covered.

Advantageously, improving the fixing of the periphery, or border, of the covering 5 makes it possible to improve the durability of the assembly while saving the amount of material and structure used in relation to a uniform fixing of the whole of the covering 5. This makes it possible to improve the efficiency of the fixing at the periphery of the covering 5. Thus, the fixing to the support 4 requires less glue , because the coating 5 is integrated into the fixing system, the central part of the coating 5 requiring less glue because maintained by its own weight. In addition, the pressures exerted on tearing being furthermore almost zero outside the periphery.

In some embodiments, the first fixing element 2 is fixed only on the surface of said support 4.

In other words, the fixing of the first fixing element 2 of the device on the support 4 is carried out without digging trenches/stringers in or around the support 4.

In other words, the support 4 has no trenches/stringers and is preferably substantially flat.

Advantageously, this makes it possible not to damage the support 4 and to facilitate the installation and the replacement of the covering 5 and of the fixing system without having to carry out major development work.

By "substantially" flat is meant a support 4 generally free of significant modifications of its surface, and which despite potential roughness and other reliefs does not include any particular structure such as a trench made for the purpose of fixing a coating thereon 5.

In certain embodiments, as illustrated by way of example and without limitation in the figure 1 , the fixing device 1 further comprises at least a second fixing element 3 coupled to the first fixing element 2 and which extends towards the inside, preferably the center, of the covering 5.

Advantageously, this makes it possible to improve the cohesion of the coating 5 on the fastening element by multiplying the points on which the pressures are applied during the use of the coating 5. Thus, instead of having a concentration of pressures of tearing suffered by the first element of fixing 2 located at the edge, said pressures will be distributed more evenly over the whole of the covering 5 and of the device.

Advantageously, the second fastening element in no way alters the essential damping function of the coating, given its thickness, its shape and its position.

In addition, the device has the additional advantage of not being affected, or only slightly, by rain and frost, because the fixing of the coating 5 is not carried out directly on the support 4, where the rain can infiltrate, stagnate and freeze, thereby damaging and/or destroying said attachment of prior art devices. Indeed, conversely in the invention, the attachment is due to the coating 5 taken from the mass of the device, partly at the level of elements of the device not being in contact with the support 4 and therefore not being , or little, in prolonged contact with water.

Nevertheless, even being in contact with the support and even if the water stagnates below, the damping coating remains maintained thanks to the system taken in the mass of the damping coating, the aggregates taken in the mesh take care of the maintenance, hence savings in the use of chemicals such as adhesion glue to the support.

In certain embodiments, the second fixing element 3 forms a mesh. Thus, the second fixing element 3 can form a net whose meshes have a round, square, diamond, honeycomb or even rectangular shape.

Advantageously, the mesh is configured to distribute the adhesion and tension forces applied to the coating 5 during its use, once said mesh is set in the mass in said coating 5.

In the figure 1 , the second fastening element 3 thus forms a net having diamond meshes, but it is possible to modify this form by another.

Advantageously, the profile of the mesh makes it possible to modify the interactions of the second fixing element 3 taken in the mass in the coating 5 with the forces applied to said ground. The mesh size can also vary, preferably between 5 and 75mm, preferably between 10mm and 30mm, more preferably 10 and 25mm.

In certain embodiments, the first fixing element 2 comprises at least a first part 21 forming a base fixed to the support 4, said base having orifices 22.

Advantageously, these orifices 22 present in the base allow both better evacuation of water while allowing better grip of the covering 5 to the first fixing element 2 by the passage of a part of said floor directly into the element of fixing by said orifices 22 of the base, and therefore a better grip.

In certain embodiments, the base 21 comprises a heightening element 9, for example a washer placed under the base 21 before its attachment, or a thickness (not shown) present directly on the face of the base 21 in contact with the support, in order to raise said base, which advantageously makes it possible to facilitate the flow of water. The booster element 9 can for example and in a non-limiting manner have a thickness of 5 mm.

Alternatively, a series of grooves, for example 3 millimeters thick and 3 millimeters deep, is made to facilitate the flow of rainwater to the outside of the coating. The dimensions of these grooves vary according to the use case and the cited example is not limiting.

In other embodiments, the raising element can also be made in the form of a concrete flashing with a thickness of approximately 5 to 10 cm, placed under the entire base, on the periphery of the covering. Advantageously, this greatly facilitates the flow of water when the support is quite porous, for example in compacted gravel, the water then being able to flow through the coating and the support through the center of the covered zone, and the periphery of the coating resting on the concrete flashing.

In certain embodiments, the coating 5 has damping properties and comprises at least one damping layer and an aesthetic layer 52 covering said damping layer, the fastening device 1 being at least embedded in the aesthetic layer 52 and/or the damping layer, and preferably both in the damping layer and in the aesthetic layer 52. The damping layer can be composed of shredded tires. The aesthetic layer 52 can also be damping. The aesthetic layer 52 can be composed of ground rubber, for example natural rubber. For example, shredded tires have a particle size between 4 and 8mm. Independently, the ground rubber exhibits, for example, a particle size of between 1 and 4 mm. The dimensions of the diaper components generally have a grain size between 1mm to 8mm.

In certain preferred embodiments, the fixing device 1 is taken in the mass of the two layers.

Thus, the components of the coating 5, for example rubber and/or tire aggregates, can pass through the meshes of the net and/or the expanded metal. After the layers of coating 5 have dried, the shredded materials are trapped in the meshes of the second fixing element 3, and it is then very difficult to dislodge the periphery, or border, of the coating 5 because it is caught, and hooked, in the fixing element.

In some embodiments, the first fastening element 2 has a second part 23 of which at least a portion forms a projection. In other words, the first fixing element 2 has a second part 23 extending away from the support 4, for example a wall having a non-zero angle with the support 4, preferably vertically with respect to the support 4. This allows the fixing device 1 to be better caught in the mass of the coating 5. In other words, this part has at least one aerial portion, facing the first part 21 of the first element, forming a base in contact with stand 4.

In other embodiments, the first fastening element 2 does not include a second part 23. It may only include a base 21 from which extends a second element 3, preferably forming a mesh.

In preferred embodiments, the portion forming a projection forms a right angle with the base of the first fixing element 2, in order to allow better gripping and a better distribution of the forces undergone during the use of the coating 5, by example by trampling.

In embodiments, the protrusion-forming portion can form various structures suitable for better caking.

The device is anchored to the support at the level of anchor points 7 present on the base 21. Preferably, these anchor points are made on a part of the base 21 close to the periphery of the coating, rather than on a part more close to the center of the coating.

In embodiments, as illustrated for example and without limitation to the figure 1 Where 3 , the extending portion forms at least one angle.

In embodiments, as illustrated for example and without limitation to the figure 5 , the extending portion forms a structure having straight walls formed by right angles.

Preferably the right angles have sharp edges, but it is possible that they have chamfers. The presence of sharp edges can improve the grip in the mass of the device with the coating 5, by the distribution of the tensile forces, and by the increase in the contact and bonding surface.

In some embodiments, the first fixing element 2 further comprises orifices 24 in the second part 23 of the first fixing element 2, for example a wall having a non-zero angle with the support 4, for example a vertical wall. These orifices 24 can for example have a round, oval or oblong shape.

Thus, the ground material can pass through the orifices 22, 24 of the base and of the wall of the first fixing element 2, the ground material then being trapped during their drying. Advantageously, this makes it possible to improve the effectiveness of caking with the coating 5 and therefore the fixing of the coating 5, without hindering the evacuation of water, the shredded material forming the different layers of the coating 5 being permeable to water. 'water.

The second fixing element 3 which will be embedded in the mass in the coating 5 can be between approximately 7 and 15 cm depending on the thickness and the surface area of the coating 5 to be produced.

The orifices 22 present on the base can for example be spaced apart by 10 cm.

In some embodiments, as shown in figure 1 , the first fastening element 2 forms at least one angle iron. This allows the floor to have an additional grip point formed by the vertical wall of the angle iron.

Thus, in a particular non-limiting embodiment, the angle iron has a height of 3 cm, a width of 6 cm.

It is possible to produce different shapes depending on the different first fixing elements of the different embodiments.

Thus, by using first fixing elements each forming an angle iron, it is possible to produce coverings 5 having the shapes of squares, rectangles, hexagonal and octagons.

In some embodiments, the angles are nestable to make bends, for example 15°, 30°, 45°, 90°, incoming and/or outgoing angles.

In certain embodiments, the first fixing element 2, for example forming an angle iron and the second fixing element 3, for example forming a mesh, can be made in one piece. In the embodiments where the second fixing element 3 forms a mesh, the mesh can be deployed at from the end of the base to then join the inclined wall, and continue beyond, towards the center of the coating 5.

In other embodiments, the two fixing elements are coupled by fixing means, for example screws or nails.

In some embodiments, as shown in figure 2 in a non-limiting manner, in which the first fixing element 2 comprises a base forming a mesh in contact with the support 4. In a non-limiting manner, it can also comprise a second part 23 forming a mesh, and forming an inclined wall, the two parts being embedded in the coating 5.

In certain embodiments, the first and second part are made of the same material, preferably in the same part.

In certain embodiments, the first part 21 forming the base has a dimension between approximately 2 to 5 cm, preferably approximately 3 to 4 cm, this dimension being able to vary according to the thickness of the covering 5 to be fixed. This may include grooves 8 or thicknesses to respectively improve water evacuation or rigidity. In certain embodiments, the second part 23 forming the net has a length of between approximately 7 cm and 18 cm, the length being able to vary according to the thickness of the covering 5 to be fixed.

In addition, the notches thus made in the mesh allow the borders to follow any profile, shape or angle. The notches can for example be spaced 15cm from each other on the base in contact with the support 4 and being adapted according to the configuration of the desired shapes.

The use of this type of fixing device 1 allows the realization of all possible shapes by bending and rounding of the net, including at the level of the angle between the base and the portion forming a projection, in other words the part Aerial. Thus, a multitude of possibilities at the level of the angle between the base and the aerial part is possible depending on the final thickness desired for the coating 5 as illustrated, by way of example, in figure 8 .

In embodiments, as illustrated without limitation in the picture 3 , the first fastening element 2 is formed of several angles. These angles each have a second part 23 of which at least one portion forms a projection, that is to say aerial parts, which can have the same height, or on the contrary have different dimensions.

In embodiments, as illustrated by way of example in picture 3 in a non-limiting way, the fixing device 1 comprises only the first fixing element 2, without thread, and is formed of 5 vertical walls connected by a base in 4 parts.

The number of vertical walls may vary depending on the embodiments. Increasing the number of vertical walls makes it possible to increase the number of attachment points and thus improve the fixing and the durability of the covering 5 on the support 4 and on the fixing device 1.

Preferably, the angles close to the center of the covering 5 each have a portion forming a higher projection than that of the angles further from the center, and therefore closer to the periphery or edge of the covering 5. In other words, the vertical walls close to the edge of coating 5 have lower heights than the vertical walls close to the center of coating 5.

The height of the walls is defined by the height of the coating 5, and must not exceed half the height of said coating 5. Regarding the end walls, they preferably measure a maximum of 1 cm in height in order to facilitate access to the playground and not represent an obstacle.

Preferably and without limitation, the highest wall cannot exceed half the height of the final coating.

In some embodiments, the bends formed between two angles can have angles between 15° and 90° in order to adapt to different configurations of desired shapes.

In some embodiments, the angles have an "L" shape, in order to form vertical walls offering an optimal contact surface with the coating 5.

In certain embodiments, orifices 22 are present over the entire first part 21 forming the base in order to guarantee the evacuation of water. These orifices 22 are preferably between 4 and 8 mm, preferably 6 mm.

During the application of the layers of the coating 5, the aggregates of the shredded material stick to the walls of the compartments as illustrated in figure 4 . The bonding surface is therefore larger. The presence of the largest wall, being the wall closest to the center of the coating 5, therefore prevents the detachment of the aggregates during trampling, the pressure being exerted mainly from the top downwards.

In embodiments, as illustrated by way of example at figure 5 in a non-limiting way, the fixing device 1 comprises a first fixing element 2, without thread, but with a first and a second part 23. The fixing element has the shape of an elongated "H", in other words a structure having straight walls, formed by right angles, and which has orifices 22, 24 allowing better evacuation of water and better maintenance of the layers of the coating 5.

In certain embodiments, the fixing device 1 is made of extruded recycled plastic. Advantageously, this makes it possible to reduce the environmental impact, thanks to a very versatile material for the production of shapes because it is very flexible and solid at the same time. In addition, this material presents less risk of cuts in the event of exposure of the fastening device 1, and cannot rust, unlike certain metals.

The material being flexible, it is possible to make all shapes, however it is also possible to provide inward and/or outward angles of 15° to 90° to make the binding more versatile.

The second part 23 of the first fixing element 2 forming a projection may comprise a vertical part and a horizontal part, the two parts possibly having orifices 24 allowing better evacuation of water and better maintenance of the adhesion of the layers of the coating 5 Grooves 8, for example in the direction of the width, can be made during manufacture under the base, first part 21 of the first element fixed to the support 4, in order to further promote the evacuation of water.

In a particular non-limiting embodiment, the dimensions of the first fixing element 2 have a height of approximately 20mm, a width of the high horizontal wall of approximately 25mm, a width at the level of the base of approximately 35 to 45mm . The first fixing element 2 can also have holes 22 of approximately 10mm, approximately every 5 cm and holes 24 on the vertical wall of approximately 10mm×30mm, approximately every 5 cm in order to ensure a better grip in the mass.

In certain embodiments, as illustrated for example and without limitation to the figure 6 , the fastening system comprises a first fastening element 2 formed for example of plastic which can be recycled, molded and/or extruded, and a second fastening element 3 forming a mesh, for example a fiberglass net. The first element 2, for example made of recycled plastic, comprises a first part 21 composed of a wall forming a base in contact and fixed with the support 4 and does not comprise a second part 23. The second fixing element 3 can be present on the whole of the base 21 or only on a part, as represented in the figure 6 .

In certain non-limiting embodiments, the wall of the first fixing element 2 has a rounded outer edge. Advantageously, this facilitates access to the playground by presenting a height at the periphery of the coating 5 that is zero or almost zero in order to reduce the risk of tripping for a young user.

In certain non-limiting embodiments, the wall has a thickness of about 5 mm which includes orifices 24, preferably 10, 20 or 30 mm in order to increase the hooking and bonding surface. Those orifices 24 promote the evacuation of rainwater and at the same time increase the gripping surface of the covering 5 in order to ensure optimum bonding.

This type of invisible edging fastener is ideal for small thicknesses of flooring 5, and it is easy to cut it to the desired degree to achieve any desired shape.

In some embodiments, the fiberglass mesh has meshes whose size is between 6mm and 25mm. The fiberglass net can be molded to the first fixing element 2, and has a length of between about 12 and 15 cm depending on the thickness of the coating 5.

During the application of the rubber aggregates, the meshes of the fiberglass mesh as well as the perforations of the part in contact with the ground trap the aggregates and form a single part, making the detachment of the aggregates very difficult or almost impossible in normal use.

In certain non-limiting embodiments, the mesh is placed halfway between the top of the covering 5 and the support 4 in order to ensure optimum maintenance of the edges of the covering 5, which has the additional advantage for the mesh of not be in contact with the support 4. The mesh is thus protected against damage due to frost, even when there is stagnant water present at the level of the support surface 4.

The figure 7 represents a coating device 5 comprising a first and a second fastening element 3, once said coating 5 has been deposited on the fastening device 1 and fixed to the support 4 by the latter. In embodiments, the two layers of the coating 5 both take the two fixing elements in the mass. Conversely, it is possible for only one of the layers, for example the aesthetic layer 52, to be in contact with the fastening element or elements.

In certain embodiments, the fixing device 1 is fixed by anchoring the base of the first fixing element 2 directly to the support 4 by anchoring means chosen from bolting, chemical or conventional anchors, for example at part of the orifices 22 of said base.

In the method of installation of the system, it is important to properly fix the fixing system to the support 4 in order to ensure good maintenance over time. Thus for a support 4 made of asphalt, a mixture of pebbles, sand and bitumen, it is necessary to use a fixing by chemical anchor, while the spitage is necessary for a support 4 of concrete.

In other words, the spitage is used in the case of a concrete support 4, while the fixing by chemical anchor is used in the case of a coated support 4.

The deposition of the glue layer is generally carried out by using a glue roller. In preferred embodiments, the deposition of glue, at least at the edges and therefore at the level of the first fixing element 2, is carried out by a pressure gun, such as a glue gun, for more precision, and for a more even spread over the entire surface to be bonded.

In certain embodiments, the fixing of the first fixing element 2 to the support 4 carried out by a bolt or by a chemical anchor according to the support 4, can be raised by 2 to 3 mm to promote the flow and the evacuation of the water, so that freezing standing water does not damage the system.

• Dépôt du dispositif de fixation 1 en bordure du support 4 à recouvrir, ledit premier élément de fixation 2 formant un périmètre délimitant ladite surface du support 4 à recouvrir,
• Fixation du premier élément de fixation 2 du système de fixation par des moyens d'ancrage configurés en fonction du support 4,
• Dépôt de colle sur au moins une partie du dispositif de fixation 1, de préférence sur tout le système de fixation,
• Mélange des composants du revêtement 5 à de la colle, puis dépôt sur le dispositif de fixation 1 et sur le support 4 à recouvrir, de façon à ce que le revêtement 5 recouvre entièrement le dispositif de fixation 1, le dispositif de fixation 1 étant alors pris dans la masse du revêtement 5, puis repos/séchage.

The present application relates to a non-claimed method of fixing a covering 5 of a support 4, without the need to dig trenches in or around said support 4, by means of a fixing device 1 comprising at least a first element of attachment 2, the method being characterized in that it comprises the following steps:

• Deposit of the fixing device 1 at the edge of the support 4 to be covered, said first fixing element 2 forming a perimeter delimiting the said surface of the support 4 to be covered,
• Fixing of the first fixing element 2 of the fixing system by anchoring means configured according to the support 4,
• Deposition of glue on at least a part of the fixing device 1, of preferably on the entire fastening system,
• Mixing of the components of the covering 5 with glue, then depositing on the fixing device 1 and on the support 4 to be covered, so that the covering 5 completely covers the fixing device 1, the fixing device 1 then being taken in the mass of the coating 5, then resting/drying.

Advantageously, following these steps makes it possible to obtain a solid and durable fixing of the covering 5, preventing the detachment of the covering 5 during the life of the covering 5. The fixing device 1 is then taken in the mass of the covering 5, and invisible to the eyes of the user, ensuring the maintenance of the coating 5 without presenting any danger to the users.

The device makes it possible to fix a coating on a bare support, but can also be used in situations of restoration of a coating in poor condition, peeled off for example. In the case where a coating is present before the installation of a device, for example in the case of a restoration of a detached coating, it is possible to cut and/or remove only the edges of the coating, in order to to access the support at its edges. The device is then fixed and then covered with the coating in order to be solidified therein. The coating can thus be deposited and glued only at the level of the edges to be replaced, leaving the center of the coating intact, still in good condition. This has the advantage of reducing the amount of materials used for a restoration, concentrating on the restoration and fixing of the more fragile edges. The edges are then fixed firmly and durably, thanks to the device.

For installation, the installer provides the thickness of the coating 5 according to the potential fall height of the installed equipment.

The glue is deposited by a pressure gun at least on the fixing device 1.

The coating 5 comprises at least one damping layer (51) and an aesthetic layer 52 covering the damping layer, and where, following the mixing of its components of each layer with glue, the damping layer is deposited on at least the support 4, and preferably on at least a part of the fixing device 1, then the aesthetic layer 52 is deposited on at least the damping layer and preferably on at least a part of the fixing device 1. In certain preferred embodiments, the deposition is carried out so that the fixing device 1 is taken in the mass of the two layers.

The user's potential fall height differs depending on the more or less high coating thickness 5 chosen.

In certain situations, for example in the case of more porous substrates, such as compacted gravel, it may be advantageous to pour a concrete substrate over said gravel, at least at the edges or periphery of the area to be covered, in order to to facilitate the attachment of the device to said edges. This has the advantage of allowing a strong and durable fixing to the periphery of the coating, while reducing the quantities of materials used for the installation of a coating on a fragile or porous support.

In a variant, above the compacted grave is fixed an aluminum expanded metal about 1 centimeter in height for example. After pouring the coating aggregates and drying, the coating is held together by the expanded metal. In this configuration, it is no longer necessary to use a bonding primer or a layer of polyurethane adhesive, usually applied before casting the aggregates, which is an environmental advantage.

The present invention also relates to a method for repairing a covering device 5 of a support 4 by means of a fixing device 1 comprising at least a first fixing element 2. This repair method is for example implemented when an existing coating device 5 suffers damage and peels off on its periphery. However, this method can also be implemented when carrying out the fixing of a new coating 5 on a support 4.

According to one mode of implementation, the method comprises a step of exposing the support 4 on the parts of the coating device 5 that need to be repaired. For a detachment at the edge of the coating, it is thus necessary to cut the part of the coating which is peeling off in order to remove it and have access to the underlying support 4.

In a first embodiment visible on the figure 9 , the method comprises the production of a first fastening element 2 along the length of the covering device 5 to be repaired, by producing a longitudinal slot 10 . This can, for example, be made in the support 4 or in an added edge 11 fixed to the support 4.

The slot 10 can be made in a support 4 when the latter is for example made of concrete, asphalt, asphalt, wood or any other material in which a slot 10 can be produced.

A slot 10 can be made in an added curb 11, when the latter is for example made of concrete curbs of type P1 or P2, asphalt, asphalt, wood or any other hard material in which a slot 10 can be made. Coated and asphalt are, for example, materials chosen so that the border 11 has a specific geometric shape at the location where this border 11 is positioned. In another embodiment of the border 11, this is a section made of recycled plastic, aluminum or any other material suitable for making a profile. The use of a profile makes it possible, for example, to make the slot 10 during the manufacture of said profile rather than making it a posteriori with a router. On a border 11, the slot 10 is for example placed on its upper part 12 or on its side part 13.

Advantageously, the slot 10 is made for example with a trapezoidal shape of the "dovetail" type, the shape of an inverted "T", a "U" slightly closed or straight on its upper part, or else all another form requiring the production of a slot 10 with a narrowed upper part and a lower part of increased size. The slot 10 has for example a depth of a few centimeters, for example 2 centimeters and has for example a width of a size ranging from a few millimeters to a few centimeters. The depth of the slot 10 requires a depth of the material in which the slot 10 is present at least greater than the depth of the slot 10, for example 4 centimeters if the slot 10 is 2 centimeters deep. The slots can be made in all shapes, all depths and all possible widths depending on the configuration, the height of the floors or the nature of the supports.

The method according to the first embodiment also comprises a step of inserting a second fixing element 3 into the slot 10. This is for example a mesh 3 which extends from the slot 10 towards the center coating 5. It has for example a width of more than twenty centimeters. This is, for example, a fiberglass net, a polypropylene mesh, an aluminum expanded metal or a perforated sheet. The mesh 3 makes it possible to maintain the coating 5 once in place thanks to its honeycomb shape.

The rest of the space of the slot is then filled with a fixing mixture 14. This mixture contains, for example, epoxy adhesive, or a chemical sealant or any other sealing material, or even, depending on its dimensions, rubber mixed with polyurethane glue and fiberglass flakes.

The coating 5 is cast on the support 4 to be coated as well as above and below the mesh 3 and the slot 10. It comprises a damping lower layer 51 and an aesthetic upper layer 52 composed for example of Diene Monomer, polyurethane glue and fiberglass flakes. The mesh 3 is taken in the coating 5, for example between the two layers or in one of the two layers. Beforehand, a layer of glue 15 mixed with fiberglass flakes is applied to the old coating 16 in order to solidify the joint between the old 16 and the new coating 5, visible figure 10 .

Following a drying step, the fixing device 1 obtained between the mesh 3 and the aggregates present in the slot 10 is taken in the mass of the covering 5 and makes it possible to fix the covering 5 to the support 4.

In a variant, the slot is replaced by a succession of holes, the bottom of the hole of which is wider than the top in order to be able to insert pieces of mesh and the coating therein so that, after drying, the coating is fixed to the support by this device taken in its mass. For example, the holes are drilled in the support or in an added border and have a frustoconical shape. In addition, the mesh pieces have for example a size of about 10 centimeters long, depending on the thickness of the coating, and a few centimeters wide. Finally, the coating is for example a mixture of aggregates and fiberglass flakes.

In a second mode of implementation of the repair process visible on the figure 10 , no slit is made. The first fixing element 2 is directly fixed to the support 4. It is for example a set of chemical plugs, plastic or brass, nails, screws or other fixing elements. These first fixing elements 2 are placed over the entire length of the covering device 5 to be repaired and are spaced apart, for example, by about fifteen centimeters.

The method according to the second mode of implementation also comprises a step of inserting a second fixing element 3 fixed between the support 4 and the first fixing element 2. This is for example a mesh 3 which extends from the first fastening element 2 towards the center of the coating 5. It has for example a width of more than twenty centimeters. These are, for example, a fiberglass net, a polypropylene mesh, an aluminum expanded metal or perforated sheet. The mesh 3 makes it possible to maintain the coating 5 once in place thanks to its honeycomb shape.

The coating 5 is then cast on the support 4 to be coated as well as over the mesh 3 and the first fixing element 2. It comprises a damping lower layer 51 and an aesthetic upper layer 52 composed for example of Ethylene-Propylene- Diene Monomer, polyurethane glue and fiberglass flakes. The color of the new aesthetic layer 52 is for example different from the original color of the old coating 16 in order to indicate that the latter has been repaired. Mesh 3 is taken from covering 5, by example between the two layers or in one of the two layers. Beforehand, a layer of polyurethane glue 15 mixed with fiberglass flakes is applied to the old covering 16 in order to durably solidify the joint between the old 16 and the new covering 5.

Following a drying step, the fixing device 1 obtained between the mesh 3 and the first fixing element 2 is taken in the mass of the covering 5 and makes it possible to fix the covering 5 to the support 4.

In a variant of the second embodiment of the visible repair method figure 11 , the first fixing element 2 is an aluminum tube with a square or round section and a diameter of between 5 and 15 millimeters depending on the final thickness of the coating 5. Aluminum is easily moldable and makes it possible to create any shape of covering periphery 5. It is fixed to the support 4 using fixing lugs 17 arranged at variable distances, for example nailed or screwed to the support. A fiberglass mesh 3 is fixed between the aluminum tube 2 and the support 4, which makes it possible to cover this fixing device 1 with the coating 5 with a thin coating. The mesh is in particular taken in the mass of the coating on its upper side and on its lower side, the coating being fixed vis-à-vis the latter since passing through the meshes of the mesh.

In a second variant of the second embodiment of the visible repair method figure 12 , the first fixing element 2 is for example a rail or a thin aluminum border fixed to the support. A mesh is fixed between the rail and the support and extends inwards. A step of covering this fixing device is then carried out with the pouring of the covering.

In a third variant of the second embodiment of the visible repair method figure 13 , the first fixing element 2 is for example a rail or a thin plastic border fixed to the support. A mesh is fixed between the rail and the support and extends inwards. A step of covering this fixing device is then carried out with the pouring of the covering.
