Abstract

Semi-independent surface coating assemblies made from synthetic resins, cement grout, epoxy cement or other liquid components which set over time are described, said assemblies comprising at least one cast base layer (3), wherein a reinforcement meshing (4) is incorporated during the casting process into the entire surface (9) to be treated, said meshing having initially been secured in various points to the substrate by distributed anchoring studs (1 and 2) fixed to the substrate (9). These wear resisting layers are seamlessly applied in a liquid state, irrespective, for example, of the surface tensile resistance of the substrate (9) to be treated and of its general surface state. The invention is useful for reconditioning damaged industrial floorings and utility surfaces.

Description

La présente invention concerne un procédé pour réaliser des revêtements de surfaces coulées sans joint, posés en semi-indépendance sur le support (9), directement circulables, mis en oeuvre à partir de résines synthétiques, de coulis de ciment ou d'époxy-ciment ou autres constituants liquides se solidifiant dans le temps.The present invention relates to a method for producing coatings on cast surfaces without joint, placed semi-independently on the support (9), directly circulating, placed work from synthetic resins, cement grout or epoxy-cement or other liquid constituents which solidify over time.

Les systèmes de surfaces techniques constituées d'un support à base de liant hydraulique et cimentaire (9), et d'une couche d'usure adhérente collée, scellée ou coulée n'est durable qu'à condition que le support et la couche en question soient de bonne qualité et que leur liaison mécanique soit parfaite.Technical surface systems consisting of a support based on hydraulic binder and cement (9), and a bonded, bonded, sealed or cast wear layer is only durable provided that the support and the layer in question are of good quality and that their bond mechanical is perfect.

Ceci implique une remise en forme de l'état de surface du support avant de lui appliquer la couche dite d'usure. Cette remise en forme s'effectue généralement par sablage, ponçage, grenaillage, rabotage, ragréage ou traitement chimique.This involves reshaping the surface condition of the support before applying the so-called wear layer. This fitness is generally carried out by sanding, sanding, shot blasting, planing, smoothing or chemical treatment.

Le dispositif innovant consiste à créer une liaison mécanique ponctuelle maillée entre le support à traiter (9) et les couches d'usure (3, 7 et 8), permettant de négliger la résistance superficielle à la traction du support à traiter et les mouvements tel que dilatation ou fissuration de ce dit support.The innovative device consists in creating a point-like mechanical link between the support to be treated (9) and the wear layers (3, 7 and 8), allowing the resistance to be neglected superficial traction of the support to be treated and movements such as dilation or cracking of this said support.

Le brevet AT-B 345521 nous décrit la pose d'un isolant sous dallage béton "épinglé" par des aciers façonnés posés avant l'isolant dans la dalle béton inférieure.Patent AT-B 345521 describes the installation of an insulation under concrete paving "pinned" by shaped steels laid before the insulation in the lower concrete slab.

Le brevet DE-A 3838320 fait état de trous réalisés dans le support à traiter, rempli par la couche de base réalisée avant la mise en place de la première couche de fibre de verre.Patent DE-A 3838320 reports holes made in the support to be treated, filled by the base layer made before the first layer of fiberglass is put in place.

Le brevet US-A 4637-946 fait état de feuilles de bitume armées de toile de verre thermodurcissable.US-A 4637-946 reports bitumen sheets reinforced with glass cloth thermosetting.

La présente invention se caractérise par la réalisation d'une liaison rigide ponctuelle assurée par des plots d'ancrage (1 et 2) logés dans le support (9) qui fixent mécaniquement une armature de treillis ou de tissus de fibres (4). L'ensemble étant ensuite saturé par coulage du nouveau revêtement.The present invention is characterized by the realization of a punctual rigid connection ensured by anchoring studs (1 and 2) housed in the support (9) which mechanically fix a reinforcement of mesh or fiber fabrics (4). The whole then being saturated by pouring the new coating.

Ces revêtements sont constitués d'une ou plusieurs couches de résines synthétiques, de coulis de ciment ou d'époxy-ciment (3, 7 et 8) d'épaisseur et de nature différentes ou identiques, élaborées à partir de un ou plusieurs composants chimiques, purs ou chargés de granulats, appliquées manuellement ou mécaniquement. These coatings consist of one or more layers of synthetic resins, grout of cement or epoxy-cement (3, 7 and 8) of different or identical thickness and nature, made from one or more chemical components, pure or loaded with aggregates, applied manually or mechanically.

L'armature (4), en treillis de fibres de verre maillé et/ou complexes de tissus de verre et/ou de composite et/ou métallique, est disposée sur toute la surface du support à traiter. Celle ci est disposée à plat et à recouvrement des lais ou des plaques (10), avant le coulage de la première couche constituante du revêtement final (3).The frame (4), made of mesh of glass fiber mesh and / or complex of glass fabrics and / or of composite and / or metal, is arranged over the entire surface of the support to be treated. This one is laid out flat and overlapped with slips or plates (10), before pouring the first constituent layer of the final coating (3).

Les plots d'ancrage sont fabriqués en produits polymères et/ou composites et/ou métalliques. Ils sont constitués d'une platine mince (1), par exemple en forme de treillis(5) et d'un pied tubulaire (2) solidaire et ajouré sur sa hauteur. Ces plots, répartis sur toute la surface à traiter suivant un plan précis, sont logés dans des trous parfaitement calibrés réalisés après la pose de l'armature (4), dans le support (9) avant le coulage de la première couche du revêtement final (3). Ces plots fixent l'armature (4) ou les plaques composites (10) sur le support à traiter (9).The anchor pads are made of polymer and / or composite and / or metallic products. They consist of a thin plate (1), for example in the form of a trellis (5) and a foot tubular (2) integral and perforated over its height. These studs, distributed over the entire surface to treat according to a precise plan, are housed in perfectly calibrated holes made after the fitting the reinforcement (4) in the support (9) before pouring the first layer of the final coating (3). These studs fix the frame (4) or the composite plates (10) to the support to be treated (9).

L'idée de base de l'invention est d'associer, par exemple, le caractère liquide d'une résine synthétique coulée, le remplissage des plots d'ancrage (1 et 2), le mouillage de l'armature (4) par la résine, fabriquant ainsi un composite fixé au support par scellement chimique.The basic idea of the invention is to associate, for example, the liquid nature of a resin synthetic casting, filling of anchor pads (1 and 2), wetting of the reinforcement (4) by the resin, thus manufacturing a composite fixed to the support by chemical sealing.

Après réticulation de la résine, par exemple dite couche de base (3), l'ensemble est parfaitement homogène, résistant et indépendant de l'état de surface initial du support (9).After crosslinking of the resin, for example called base layer (3), the assembly is perfectly homogeneous, resistant and independent of the initial surface condition of the support (9).

La fiabilité du dispositif repose sur l'amélioration des modules d'élasticité du revêtement et de la résistance à l'arrachement des plots d'ancrage et de la liaison "plots-couche de base".The reliability of the device is based on improving the elasticity modules of the coating and the resistance to tearing off of the anchoring studs and of the “studs-base layer” connection.

La couche de base (3) peut ensuite recevoir une ou plusieurs autres couches constituant le nouveau revêtement. Celles-ci seront alors les couches d'usure (7 et 8).The base layer (3) can then receive one or more other layers constituting the new coating. These will then be the wear layers (7 and 8).

La couche de base (3) peut être constituée d'éléments préfabriqués de dimension adaptée (10)et (11), armés d'un treillis de fibres (4), fixés au support (9) par les plots (1 et 2) et recouvrant le sol à traiter. Dans ce cas, ce sont les couches d'usure (7 et 8) qui saturent les recouvrements et remplissent les plots d'ancrage.The base layer (3) can consist of prefabricated elements of suitable size (10) and (11), armed with a fiber mesh (4), fixed to the support (9) by the studs (1 and 2) and covering the soil to be treated. In this case, it is the wear layers (7 and 8) which saturate the overlaps and fill the anchor pads.

La présente invention vise à supprimer les inconvénients de la préparation du support (9). On notera par ailleurs que le caractère semi-indépendant du dispositif innovant concourt à ce que le revêtement ne subisse pas de décollement sous l'effet d'éventuels phénomènes de flux de vapeur d'eau ou de gaz, de pression hydrostatique ou de fissuration du support (9).The present invention aims to eliminate the drawbacks of the preparation of the support (9). We also note that the semi-independent nature of the innovative device contributes to the fact that the coating does not undergo detachment under the effect of possible phenomena of flux of water vapor or gas, hydrostatic pressure or cracking of the support (9).

Le procédé prévoit également la possibilité de la mise en place, sous l'armature (4) ou la couche de base préfabriquée (10), d'un matériau isolant phonique et/ou d'un matériau drainant non collé et/ou existant et fixé par les plots (1 et 2) au support (9), en même temps que la fixation de l'armature (4) ou des plaques (10). Pour réaliser la semi-indépendance certaine, le support (9) peut être traiter en surface par la mise en oeuvre d'un agent démoulant avant la pose de l'armature ou autre produit chimique et/ou solide. The method also provides for the possibility of placing under the frame (4) or the prefabricated base layer (10), soundproofing material and / or draining material not glued and / or existing and fixed by the studs (1 and 2) to the support (9), at the same time as the fixing the frame (4) or plates (10). To achieve certain semi-independence, the support (9) can be treated on the surface by the use of a release agent before the fitting of the reinforcement or other chemical and / or solid product.

Tel qu'il est conçu, le dispositif permet le contrôle et la maítrise des migrations d'eau à l'interface du support (9) et du revêtement (3, 7 et 8).As designed, the device allows the control and mastery of water migrations to the interface of the support (9) and of the coating (3, 7 and 8).

La présente invention est particulièrement destinée à la réfection des sols et surfaces dégradés dans les secteurs de l'Industrie Agro-Alimentaire, Chimique, Para chimique, Métallurgique et Technique en général.The present invention is particularly intended for the repair of degraded floors and surfaces in the Food, Chemical, Para-chemical, Metallurgical and Technical in general.

Selon l'invention, les supports susceptibles de recevoir ce système sont principalement des subjectiles à liant hydrauliques cimentaires ou revêtus d'un revêtement existant pouvant comporter des irrégularités de surface, des salissures et des aspérités.According to the invention, the supports capable of receiving this system are mainly cementitious hydraulic bonded substrates or coated with an existing coating that can have surface irregularities, dirt and roughness.

Concernant les supports inclinés et verticaux, le principe de l'invention est conservé : Le remplissage des plots d'ancrage (1 et 2) est réalisé par injection d'une résine de scellement et l'application des couches de résines (3, 7 et 8) dites de base et d'usure se fait par projection sur le support ou au rouleau.Regarding inclined and vertical supports, the principle of the invention is preserved: filling of the anchor pads (1 and 2) is carried out by injection of a sealing resin and the application of the so-called base and wear layers of resins (3, 7 and 8) is by spraying on the support or on the roller.

Le procédé tel qu'il est conçu, renforce la structure du support (9) par l'imprégnation des aspérités et des micro-fissures par de la résine qui remplit le pied tubulaire du plot d'ancrage (2).The method as it is designed strengthens the structure of the support (9) by impregnating the roughness and micro-cracks by resin which fills the tubular base of the anchoring pad (2).

Le procédé tel qu'il est conçu, peut recevoir sur la sous-couche un revêtement collé du type dallette PVC ou carrelage par exemple, en revêtement de finition superficiel.The process as it is conceived, can receive on the underlayer a glued coating of the type PVC slab or tiling for example, in surface finish coating.

Appliqué avec des résines synthétiques par exemple, le procédé permet de réaliser des surfaces étanches aux liquides.Applied with synthetic resins for example, the process allows for liquid tight surfaces.
