L'élément d'isolation est formé 'par plusieurs briques complétées par une coque en forme de U. 30 On connaît également le brevet français FR1576243 qui décrit une brigue creuse comportant des ouvertures, notamment destinée à être utilisée comme brique d'insonorisation et/ou comme brique d'aération, dans laquelle 35 une plaque frontale perforée est pourvue de parois latérales 15 2973406 - 2' - dirigées vers l'arrière. Les parois latérales forment un cadre autonome. La plaque frontale et le cadre peuvent être séparément fabriqués à la boudineuse, puis assemblés l'un à l'autre par collage. Les bords périphériques extérieurs du 5 cadre sont décalés vers l'intérieur par rapport aux bords périphériques correspondants de la plaque frontale de préférence tous de la même quantité. European Patent EP0580096 discloses a parallelepiped acoustic insulation element having a hollow space, a longitudinal wall of which has a plurality of holes passing through the hollow space. A soundproofing lining is disposed in this hollow space. The insulation element is formed by several bricks supplemented by a U-shaped shell. French patent FR1576243 is also known which describes a hollow bar having openings, in particular for use as a soundproof brick and / or or as a ventilation brick, in which a perforated faceplate is provided with rearwardly directed side walls 2973406 - 2 '-.

Inconvénients des matériaux de l'art antérieur Disadvantages of the materials of the prior art
Les solutions de l'art antérieur nécessitent l'assemblage de plusieurs matériaux, ou impliquent le recours 20 à des procédés de fabrication complexes et coûteux. The solutions of the prior art require the assembly of several materials, or involve the use of complex and expensive manufacturing processes.
Par ailleurs, les solutions proposées sous la forme de blocs de maçonnerie n'améliorent les qualités acoustiques que dans une bande de fréquence donnée et ne permettent pas 25 d'atténuer de manière significative la transmission sonore entre deux locaux.

DETAILED DESCRIPTION OF NON-EXCLUSIVE EMBODIMENTS The invention will be better understood on reading the description which follows, with reference to the appended drawings relating to nonlimiting examples of embodiment, in which: FIG. 1 is a perspective view of Reference 2 of a masonry block - FIG. 2 is a view along the transverse sectional plane of a masonry block according to the invention; FIG. 3 represents the response curve of a wall consisting of masonry blocks according to FIG. The invention compared to a wall consisting of building elements of the state of the art - Figures 4 to 6 show different wall configurations made in application of the invention - Figure 7 shows an alternative embodiment of the invention. a brick according to the invention.
La figure 1 est une vue schématique du référentiel d'une brique, représentant un bloc de construction connu (1) 35 de forme parallélépipédique. La hauteur, correspondant à la direction des cavités traversant le bloc sera désigné par l'axe Y. Les deux axes perpendiculaires, l'axe longitudinal X, et l'axe transversal Z, définissent un plan S2 qui sera désigné par « plan transversal ». Il est perpendiculaire à la hauteur Y. La figure 2 représente un exemple de réalisation d'un matériau de construction selon l'invention, selon un plan de coupe transversal XZ. Figure 1 is a schematic view of the reference frame of a brick, representing a known building block (1) 35 of parallelepiped shape. The height, corresponding to the direction of the cavities passing through the block, will be designated by the Y axis. The two perpendicular axes, the longitudinal axis X, and the transverse axis Z, define a plane S2 which will be designated by "transverse plane". . It is perpendicular to the height Y. FIG. 2 represents an exemplary embodiment of a building material according to the invention, according to a cross-sectional plane XZ.
Le matériau est réalisé dans l'exemple décrit en terre cuite, et présente des cavités orientées selon l'axe Y, de forme et de dimension non homogènes. The material is made in the example described in terracotta, and has Y-oriented cavities of non-homogeneous shape and dimension.
Dans l'exemple décrit, le matériau présente une première cavité (2) de section rectangulaire séparée par une paroi transversale traversante (3) d'une deuxième cavité (4) de forme rectangulaire, et d'une section inférieure à la première cavité (2). La largeur de cette deuxième cavité (4) est identique à celle de la première cavité (2), et sa longueur mesurée selon l'axe transversal Z est inférieure à celle de la première cavité (2). In the example described, the material has a first cavity (2) of rectangular section separated by a transverse transverse wall (3) of a second cavity (4) of rectangular shape, and a lower section to the first cavity ( 2). The width of this second cavity (4) is identical to that of the first cavity (2), and its length measured along the transverse axis Z is less than that of the first cavity (2).
Une nouvelle cloison transversale traversante (5) sépare cette deuxième cavité (4) d'une troisième cavité rectangulaire (6).La largeur de cette troisième cavité (6) est identique à celle des deux autres cavité (2, 4), et sa longueur mesurée selon l'axe transversal Z est inférieure à celle des cavités (2, 4). A new transverse transverse partition (5) separates this second cavity (4) from a third rectangular cavity (6). The width of this third cavity (6) is identical to that of the two other cavities (2, 4), and its length measured along the transverse axis Z is smaller than that of the cavities (2, 4).
Après une troisième cloison transversale traversante (7), la brique présente une nouvelle cavité (8) excentrée, de section sensiblement carrée et de coté inférieur à la longueur des autres cavités. 2973406 6' Une nouvelle cloison transversale traversante (9) sépare cette cavité carrée (8) d'une cinquième cavité (10) de section rectangulaire, et d'une longueur intermédiaire à celle des autres cavités (2, 4, 6). 5 Cette brique selon l'invention est extrudée selon l'axe Y pour constituer un volume de 27 centimètres par 31,4 centimètres, par 21 centimètres. After a third transverse transverse partition (7), the brick has a new cavity (8) eccentric, of substantially square section and lower side to the length of the other cavities. A new transverse transverse partition (9) separates this square cavity (8) from a fifth cavity (10) of rectangular section, and of an intermediate length to that of the other cavities (2, 4, 6). This brick according to the invention is extruded along the Y axis to constitute a volume of 27 centimeters by 31.4 centimeters, by 21 centimeters.
La figure 3 représente la courbe de réponse d'une 10 brique selon l'invention comparée à une brique de l'état de la technique. Les deux briques ont les mêmes dimensions externes et la même masse volumique. Figure 3 shows the response curve of a brick according to the invention compared to a brick of the state of the art. Both bricks have the same external dimensions and the same density.
On observera que la perte acoustique de la brique 15 selon l'invention est nettement supérieure à la perte acoustique de la brique selon l'état de la technique, les différences variant entre quelques décibels dans les fréquences de 100 hertz et de 1048 Hz, à des atténuations de plus de 15 décibels pour certaines fréquences comprises entre 20 300 et 1000 Hertz, qui correspondent au bruit ambiant en milieu urbain. It will be observed that the acoustic loss of the brick 15 according to the invention is clearly greater than the acoustic loss of the brick according to the state of the art, the differences varying between a few decibels in the frequencies of 100 Hz and 1048 Hz, at attenuations of more than 15 decibels for certain frequencies between 20 300 and 1000 Hertz, which correspond to the ambient noise in an urban environment.
Les figures 4, 5 et 6 représentent différentes configurations de parois selon l'invention. La figure 4 représente une paroi réalisée avec une adjonction de briques à répartition irrégulière de cavités, conforme à celle représentée en figure 2, disposées toutes dans le même sens.
