Definitions

  • the present invention relates to a floor system comprising a floating screed and separators arranged under said floating screed.
  • a falling object, the footsteps of people moving around, or the movement of an object on a floor with poor acoustic properties in an adjacent room can be a significant source of noise pollution for the activities taking place there.
  • Such a floor can also reflect the sound waves emitted during these activities and cause reverberation, degrading the acoustic comfort necessary for their smooth running.
  • Libraries, museums, schools, train station halls, restaurant dining rooms, and event halls are all examples of places where a reduction in noise pollution is often sought.
  • a reduction in impact noise on floors is generally desired to ensure the peace and quiet of residents.
  • floor systems comprising functional elements that attenuate the propagation of sound or acoustic waves are used as floor coverings.
  • These functional elements are generally in the form of an insulation layer that reduces the intensity of the mechanical coupling between the structural element supporting the floor and the upper part of the floor on which it is possible to walk.
  • the patent KR101704909 B1 discloses an insulation layer comprising cells into which hollow capsules can be inserted to absorb shock waves.
  • the utility model CN201486105 U and demand JPH04293857 disclose insulation layers formed by separating pads arranged between a structural element and the upper part of a floor.
  • the documents DE3503529A , KR20100086226A And KR20110130910A show floor systems including a floating screed.
  • the present invention improves the acoustic performance of existing floating screed floor systems.
  • the invention provides a floor system according to claim 1, as well as a kit for manufacturing such a floor system according to claim 12 or 13, and a method for manufacturing such a floor system according to claim 14.
  • Preferred embodiments are defined in the dependent claims.
  • a floor system comprising a floating screed and separators arranged under said floating screed, in which the separators are in point and/or linear contact with the surface of an underlying element capable of serving as a support for the floor system and with the surface of an overlying layer arranged between said floating screed and said separators, and in which the overlying layer is based on resilient material.
  • the separators separate the underlying element and the overlying layer in such a way that they are not in contact with each other and form a network of hollow cavities between the underlying element and the overlying layer, the separators are not based on resilient material, the Young's modulus of the overlying layer is less than or equal to 1 GPa at 20°C, and the Young's modulus of the separators is greater than 20 GPa at 20°C.
  • the function of the separators is to separate the underlying element and the overlying layer so that they are not in contact with each other.
  • the separators may assist in the formation of a hollow cavity and/or a network of hollow cavities between the underlying element and the overlying layer.
  • the separators may be solid or hollow.
  • point and/or linear contact is understood to mean a point and/or linear contact of Hertzian type, generally without friction.
  • Two bodies are said to be in point and/or linear contact of Hertzian type when the contact surfaces between two bodies result solely from the elastic and/or plastic deformation of one or both bodies when they are subjected to a compressive load, without these two bodies having had a common contact surface before any deformation.
  • a contact between two bodies is said to be surface when the two bodies are in contact with each other by a surface existing prior to any elastic and/or plastic deformation of one or both bodies when they are subjected to a compressive load.
  • the term "screed” has a broader definition than that of standard EN 13318:2000. It is defined as a layer or set of layers of material placed on a support or on a set of layers intermediate, possibly insulating, in order, for example, to reach a specific level, to receive another floor covering and/or to serve as a finished floor. It covers so-called “wet” screeds and so-called “dry” screeds.
  • wet screeds generally refer to screeds that are in liquid or paste form when placed on the substrate intended to receive them and then harden after setting and drying.
  • wet screeds are screeds based on cement, synthetic resin, calcium sulfate, magnesia and/or bitumen emulsion.
  • the most common wet screeds are cement mortar screeds.
  • Dry screeds generally refer to slabs in the general sense, boards or rigid panels that can be placed side by side. Examples are plasterboard or cement-based boards. They can optionally be reinforced with cellulose fibers or glass fibers.
  • the "floating screed”, also called a raised screed or a detached screed designates, in accordance with the practices in the field of construction, a screed with little or no adhesion to the support on which it is laid. It is also little or not integral with the other structural elements.
  • the underlying element that can serve as support for the floor system can be any structural element suitable for the installation of a floor system. In general, it is a flat structure or a surface that appears horizontal. For example, it can be a concrete or mortar slab, bare or possibly covered with one or more surface coverings formed from juxtaposable manufactured elements such as ceramic, stone, resin, thermoplastic or wood tiles or slabs. It can also be a concrete, wood or metal floor. It can also include a sound and/or thermal insulation covering.
  • resilient used to describe a material, designates a material capable of absorbing energy when it is elastically deformed and of restoring it all or in part when the deformation stress is removed.
  • resilient materials are elastic materials such as rubber, cork, expanded polystyrene, viscoelastic materials such as polyurethane, silicone, polyacrylate, or mineral wools such as rock wool or glass wool.
  • the main advantage of the floor system according to the invention is a gain of 25 to 110% in the reduction of the weighted impact noise level compared to a floor system according to the state of the art.
  • the reduction in the weighted impact noise level, ⁇ L w , of a floor system according to the invention compared to a reference floor is generally between 18 and 30 dB.
  • the reference floor is defined by the same standards NF EN ISO 10140:2013 and NF EN ISO 717-2:2013. It is a concrete slab with a thickness of 140 mm.
  • a second advantage is that it can be used on existing floors and/or floors, for example in the case of renovation, as long as these floors and floors are suitable for supporting another floor covering.
  • a third advantage is that, in the case where the floating screed is a wet screed, the screed in liquid or paste form can be poured directly onto the overlying layer.
  • the separators are convex-shaped particles.
  • a convex shape ensures point and/or linear contact of the separators with the surface of the underlying element likely to serve as support for the floor system and with the surface of the overlying layer. The higher the degree of convexity of the outer surface of the particles, the smaller the area of the contact surface and the higher the noise reduction level of the floor system becomes.
  • the separators can have regular or irregular geometry. Preferably, they are spherical or cylindrical particles. These types of shapes generally minimize the area of the point and/or linear contact surfaces of the separators with the underlying element and the overlying layer.
  • the Feret diameter is the maximum distance between two parallel lines between which the separator can geometrically fit.
  • the Féret diameter of the separators is between 1 and 100 mm, preferably between 3 and 70 mm. These particle sizes make it possible to avoid excessively high levels of the of the upper surface of the floor system relative to the surrounding structure in which it is installed.
  • the distribution density of the separators between the underlying element and the overlying layer may vary, in particular depending on the size of the separators and the condition of the surface of the underlying element likely to serve as support for the floor system.
  • the distribution density of the separators is between 10 and 2500 separators per square meter, preferably between 100 and 2500 separators per square meter. This density range is optimal for a homogeneous distribution of the separators on the surface of the underlying element and the formation of a hollow cavity and/or a network of hollow cavities.
  • the separators are distributed over the underlying element in a regular geometric pattern.
  • a regular geometric pattern corresponds to any type of pattern formed by periodic tiling of a symmetrical or asymmetrical regular sub-pattern. Examples of patterns are squares, rectangles, pentagons, hexagons, alone or in combination.
  • the separators are cords forming a mesh.
  • the cords may be in the form of a grid with a woven or non-woven mesh.
  • the cords may be solid or hollow.
  • the distance between two cords of the mesh may be between 1 mm and 30 cm.
  • the overlying layer is based on a resilient material.
  • the Young's modulus of the overlying layer is less than or equal to 1 GPa at 20°C.
  • the separators are based on a resilient material. The Young's modulus of the separators is less than or equal to 1 GPa at 20°C.
  • the overlying layer is based on a resilient material.
  • the Young's modulus of the overlying layer is less than or equal to 1 GPa at 20°C.
  • the separators are not based on a resilient material.
  • the Young's modulus of the separators is greater than 20 GPa at 20°C.
  • the overlying layer may be based on a material selected from expanded polystyrene, rubber, silicone, polyurethane, mineral wool, woven or non-woven glass fibers or a combination thereof.
  • the thickness of the overlying layer may advantageously be between 10 and 200 mm, preferably between 20 and 80 mm.
  • Separators can be made of wood, thermosetting resin, mineral material or organic material.
  • mineral material are glass, ceramic, concrete, mortar, granular composites.
  • the overlying layer is not based on a resilient material.
  • the Young's modulus of the overlying layer may in particular be greater than 1 GPa at 20°C.
  • the separators are based on a resilient material. The Young's modulus of the separators is preferably less than or equal to 1 GPa at 20°C.
  • the overlying layer may be based on a material selected from plaster, cork, wood or their combination and/or the separators may be based on a material selected from expanded polystyrene, latex, silicone elastomer, polyurethane, rubber, mineral fibers, organic fibers, or their combination.
  • the thickness of the overlying layer may advantageously be between 0.5 and 50 mm, preferably between 2 and 30 mm.
  • the viscoelastic damping rate of the separators may advantageously be equal to or greater than 5% at 20°C.
  • This damping rate may be measured by dynamic mechanical analysis, also dynamic mechanical spectrometry, in which the material of the separators is subjected to oscillatory mechanical stress. It generally corresponds to the ratio of the loss modulus to the storage modulus.
  • the separators can be fixed to the surface of the overlying layer. This fixing is prior to the manufacture of the floor system.
  • This embodiment has the advantage of simplifying the manufacture of the floor system since the step of dispersing the separators on the underlying element is no longer necessary.
  • overlying layer/separator assembly also has the advantage of allowing the overlying layer/separator assembly to be packaged in transportable formats suitable for construction sites. It can, for example, be packaged in the form of a ready-to-use roll for use, which may be rolled out over an underlying element capable of supporting the floor system before installing a floating screed above said overlying layer.
  • the quantity and distribution of the separators fixed on the surface of the overlying layer is such that no contact is formed between the overlying layer and the underlying element likely to serve as support for the floor system when the floating screed is installed on the overlying layer.
  • the overlying layer may be a deformable film or fabric. It may advantageously be a waterproof film in order to reduce the possibility of water infiltration towards the separators and the underlying element when a wet floating screed is implemented on the overlying element.
  • a kit comprising a floating screed preparation and an overlying layer on the surface of which separators are fixed.
  • an overlying layer for example, a film, a veil or a fabric
  • a first direction using of a conveyor.
  • the nozzles can directly deposit glue-coated separators or separators having at least on their surface a non-crosslinked or non-polymerized state allowing their attachment to the overlying layer by subsequent crosslinking or polymerization.
  • an overlying layer for example, a film, a veil or a fabric
  • a roller is in contact with the upper surface of the overlying layer. It is driven by a rotational movement in the opposite direction to the conveying direction. It is provided with at least one given negative relief, such as an asperity, a cavity or a concavity of a given shape.
  • a reservoir, filled with glue is arranged above and in contact with the roller. With each rotation, the negative relief is filled with a quantity of glue, which then unwinds onto the upper surface of the overlying layer to form a spot or bead of glue when it comes into contact with said surface during the rotation.
  • the size of the relief, the number of reliefs and the rotation speed determine the quantity and distribution of the spots or beads of glue.
  • the separators are deposited on the spots or beads of glue in a subsequent step.
  • An advantage of the first and second methods is that they allow for the continuous manufacture of an overlying layer/separator assembly.
  • a first step is to deposit glue on the surface of an overlying layer using a screen printing method.
  • the screen printing screen has a number and distribution of holes corresponding to the desired number and distribution of separators in contact with the surface of the overlying layer.
  • the separators are arranged on the glue pads or beads in a later step, once the latter have been deposited using the screen printing screen.
