Abstract

The Acoustic Joint (1 to 7) will be used for floor coverings on acoustic screeds. .The seal ensures the continuity of the function of the sound insulation (8). It makes it possible to avoid poor workmanship which leads to non-conformities with the acoustic regulations of the building. The Seal (1 to 7) is made of elastomeric material, it consists of 2 lips (1 and 2). This seal is placed on the periphery of a room. Between the 2 lips is inserted the floor covering (11). The underside of the seal will be fitted with a self-adhesive system with a detachable adhesive sheet (7). The lower lip (1) has notches (6) allowing the glue (10) to spread. The seal separates the floor covering (11) and the plinth (13) from the vertical walls (14), it cuts the solid transmission chain of the impact noise. . Figure for the abstract: Fig6

Description

Acoustic seal for flooring

The present invention named: the Acoustic Seal for Flooring relates to an accessory material to be used in the field of construction. Whether the construction is: real estate, tertiary, hospital, college, university, individual and others. This material is an accessory intended for work involving the installation of floor coverings (tile, parquet or stone type coverings) on acoustic or thermo-acoustic screeds. Its functions are: to ensure perfect separation of the floor coverings against the edges of the floor covering and all the vertical walls of all kinds making up the room or room in which the floor covering is installed (edges made up of: wall concrete, brick wall, all types of partitions, all types of thermal lining, all types of acoustic lining) and to ensure the free expansion of materials. All of this flooring and accessory work is carried out in compliance with the rules of construction art, the NFP standards in force (DTU 52.5 of December 2009, NFP 61-204, DTU 52 -2).

1. La réalisation d’un joint de dilatation en périphérie des surfaces et des locaux dans lesquels sont posés les revêtements de sol. Selon DTU et norme NFP ce joint est de 3 millimètres à minima dans les cas courant et de 5 millimètres pour des planchers chauffant: ce joint est réalisé manuellement.
2. La réalisation d’une désolidarisation par un joint situé entre la surface plane et horizontale du revêtement de sols et la plinthe périphérique posée verticalement sur la paroi du local concerné: ce joint est réalisé manuellement.
3. Empêcher et éviter que les produits de collage ou le coulis de rejointoiement (cas du revêtement en carrelage ou pierre) ne viennent s’infiltrer ou combler les joints détaillés ci-avant: cette tâche est manuelle.
4. Finir la mise en place de l’isolant acoustique qui doit être positionné entre la plinthe verticale et le revêtement de sol horizontale. Puis découpage de l’isolant qui dépasse au-delà plinthe: cette tâche est manuelle.
5. Réaliser la finition de l’ouvrage de revêtement de sols par un «joint pompe» qui reste visible: cette tâche est manuelle.
6. Il est à noter que ce «joint pompe» doit être remplacé dans le temps notamment lorsqu’il est situé dans un local ou une pièce dite humide (salle de bains, WC, cuisine etc.). La fréquence de son remplacement dépend de la durée d’utilisation mentionnée sur la fiche technique du produit «joint pompe» utilisé.

The present invention, the acoustic seal for flooring, has the function of replacing several manual tasks which are carried out by the companion-worker who implements the flooring and its accessories in order to guarantee good acoustic insulation between the premises or rooms that are contiguous or superimposed. These successive tasks which are carried out manually by the worker are by definition "random" and therefore may present an implementation defect called "solid-borne contact and transmission of noise", which degrades the acoustic quality of the work and may lead to non-conformities. vis-à-vis: the acoustic regulations according to the decree of June 30, 1999 and the criteria of the various certifications, in particular specific to housing: NF Habitat. These non-conformities entail heavy rework or repairs which induce delays in the deadlines and additional costs for the work. These different tasks carried out manually by the journeyman – flooring worker are:

1. The creation of an expansion joint on the periphery of the surfaces and rooms in which the floor coverings are laid. According to DTU and NFP standard, this joint is at least 3 millimeters in common cases and 5 millimeters for heated floors: this joint is made manually.
2. The realization of a separation by a joint located between the flat and horizontal surface of the floor covering and the peripheral plinth placed vertically on the wall of the room concerned: this joint is made manually.
3. Prevent and avoid that the bonding products or the repointing grout (in the case of tile or stone covering) from infiltrating or filling the joints detailed above: this task is manual.
4. Finish installing the acoustic insulation which must be positioned between the vertical plinth and the horizontal floor covering. Then cut the insulation that protrudes beyond the baseboard: this task is manual.
5. Finish the floor covering work with a “pump seal” which remains visible: this task is manual.
6. It should be noted that this "pump seal" must be replaced over time, especially when it is located in a so-called wet room or room (bathroom, WC, kitchen, etc.). The frequency of its replacement depends on the duration of use mentioned on the technical data sheet of the “pump seal” product used.

The present invention, named: Acoustic seal for flooring, responds factually to the problem posed by changes in the acoustic regulations in force for the acoustic insulation of buildings, in particular for residential use. Indeed, professionals in the construction sector (Prime contractors, Architects, Technical studies office, Contractors and suppliers) have recommended the production of so-called acoustic screeds (or thermo-acoustic screeds) These acoustic screeds meet the standard of DTU 52-10 which describes an acoustic insulation of the floors carried out by the installation of a thin acoustic insulation under the concrete screed (or in another material). This acoustic insulation improves the comfort of the habitat or the other use of the room and, it attenuates impact noise in adjacent, contiguous or superimposed rooms. In addition, the vertical rise of the acoustic insulation on the periphery (or by using an accessory product) must ensure separation of the screed and the floor covering from the vertical walls located on the periphery of the floor covering: this that is to say to eliminate all the possibilities of transmission of structure-borne noise emitted in a room or a room in another room or room. These structure-borne transmissions are the source of the majority of non-compliance with acoustic regulations and/or housing certification. However, this process of acoustic screeds, which is effective, has a sensitive zone and a weak point located at the junction of the horizontal floor covering and the baseboard or the vertical wall which is at the periphery because it is carried out by a succession of manual tasks described above. -before: all manual tasks are by definition random.

It is sometimes found that the acoustic insulation which must protrude vertically above the screed is either cut, torn or damaged, which does not allow to pass and carry out the next stage without a recovery and repair of the defects of work concerned.

1. Horizontalement, la chape sur laquelle sera mis en œuvre le revêtement de type par exemple carrelage.
2. Verticalement, en périphérie de la pièce ou du local une paroi au pied de laquelle doit dépasser l’isolant acoustique sur une hauteur de 10 à 15 cm.

L’ensemble de ces tâches sont réalisées par un ou plusieurs opérateurs différents et génèrent un risque majeur de malfaçons.The prior art for a floor covering of the tile type includes the following tasks to be carried out from a support which is constituted by:

1. Horizontally, the screed on which the tiling type covering will be applied.
2. Vertically, on the periphery of the room or premises, a wall at the foot of which the acoustic insulation must protrude to a height of 10 to 15 cm.

   • b5: Cut the part of the acoustic insulation that protrudes from the foot of the plinth.
   • b6: Make a finishing joint to fill and seal the free space between the skirting board and the tiles.

All of these tasks are carried out by one or more different operators and generate a major risk of poor workmanship.
