Description

La présente invention concerne un élément de construction sous une forme d'une poutre ou d'un panneau comprenant un assemblage de parois longitudinales et d'entretoises, destiné à l'érection d'un mur d'habitation ou de bureau.The present invention relates to a structural element in the form of a beam or a panel comprising an assembly of longitudinal walls and spacers, intended for the erection of a residential or office wall.

Le document FR 3 022 569 divulgue une poutre comprenant deux parois latérales et une paroi interne, longitudinales et parallèles, délimitant des espaces internes dans lesquels sont localisés une série d'entretoises et d'éléments d'isolation. Ces entretoises sont agencées perpendiculairement aux parois longitudinales. Les entretoises d'un premier espace entre une paroi latérale et la paroi interne sont décalées par rapport à celles localisées dans le second espace entre l'autre paroi latérale et la paroi interne. Ces entretoises sont régulièrement réparties, tandis qu'une entretoise du premier espace est localisée à la moitié de l'écartement de deux entretoises agencées dans le second espace.The document FR 3,022,569 discloses a beam comprising two longitudinal and parallel side walls and an inner wall, defining internal spaces in which are located a series of spacers and insulation elements. These spacers are arranged perpendicularly to the longitudinal walls. The spacers of a first space between a side wall and the inner wall are offset from those located in the second space between the other side wall and the inner wall. These spacers are regularly distributed, while a spacer of the first space is located at half the spacing of two spacers arranged in the second space.

Ces poutres sont fabriquées par pressage des parois longitudinales, collées au contact des entretoises et des éléments d'isolation. Cette structure régulière des entretoises engendre un effet de vague longitudinale de la poutre résultante, lors de l'assemblage sous presse. Cet inconvénient est surmonté en partie par l'utilisation d'éléments d'isolation ayant un taux de compression faible. La présence de ces éléments d'isolation compactes, attenue les déformations longitudinales dues au pressage, en contribuant à transmettre les efforts de pressage. Cependant, cette structure de poutre est limitée aux isolants ayant un taux de compression faible.These beams are manufactured by pressing the longitudinal walls, glued in contact with the spacers and insulating elements. This regular structure of the spacers generates a longitudinal wave effect of the resulting beam, during assembly in press. This disadvantage is overcome in part by the use of insulation elements having a low compression ratio. The presence of these compact insulation elements, attenuates the longitudinal deformations due to the pressing, contributing to transmit the pressing forces. However, this beam structure is limited to insulators having a low compression ratio.

Précisons que lors du pressage, les parois latérales sont au contact de la presse, c'est donc la paroi interne qui subit les déformations qui sont ensuite répercutées sur les parois latérales. Ces déformations sont permanentes, résultant en un produit final gondolé.Note that during pressing, the side walls are in contact with the press, so it is the inner wall that undergoes the deformations that are then reflected on the side walls. These deformations are permanent, resulting in a final curled product.

Usuellement, des poutres formées de placage de bois sont assemblées sous une pression de 8 bars/cm2.Usually, beams formed of wood veneer are assembled under a pressure of 8 bar / cm 2 .

Plus la pression est élevée et plus le collage est favorisé, à savoir que la qualité du collage est accrue.The higher the pressure, the more the bonding is favored, namely that the quality of the bonding is increased.

Les poutres précédemment décrites sont communément assemblées sous une pression entre 2 et 2,5 bars/cm2. Un pressage de ces poutres à une pression plus élevée, même en présence d'isolant ayant un taux de compression faible, engendre une déformation longitudinale permanente.The previously described beams are commonly assembled under a pressure between 2 and 2.5 bar / cm 2 . Pressing these beams to a higher pressure, even in the presence of insulation with a low compression ratio, causes permanent longitudinal deformation.

Il serait avantageux de pouvoir se libérer de la contrainte d'intégrer des isolants ayant un taux de compression faible, pour pouvoir ouvrir la voie à l'intégration d'isolant ayant un taux de compression élevé.It would be advantageous to be able to release the constraint of integrating insulators having a low compression ratio, in order to open the way to the integration of insulation with a high compression ratio.

En vue de l'optimisation des performances isolantes d'un mur, il est souhaité d'utiliser des éléments d'isolation fibreux, qui sont en général extrêmement compressibles. De nombreux matériaux ayant un taux de compression élevé, ont d'excellentes performances, en termes notamment de conductivité thermique, il serait ainsi judicieux de pouvoir les intégrer dans une structure de poutre à multiples compartiments.In order to optimize the insulating performance of a wall, it is desired to use fibrous insulation elements, which are in general extremely compressible. Many materials having a high compression ratio, have excellent performance, in particular in terms of thermal conductivity, it would be wise to integrate them in a beam structure with multiple compartments.

Il serait également judicieux de pouvoir produire des poutres ou des panneaux sans éléments d'isolation, ce qui n'est pas réalisable à ce jour. Ces poutres ou panneaux sans éléments d'isolation assemblés lors du pressage, étant modulables par l'insertion à postériori d'isolants en vrac déversés après érection d'un mur.It would also be wise to be able to produce beams or panels without insulation, which is not feasible to date. These beams or panels without insulation elements assembled during pressing, being adjustable by the insertion after the bulk insulators dumped after erection of a wall.

La présente invention propose une poutre ou un panneau, permettant de pallier les inconvénients précités.The present invention provides a beam or a panel, to overcome the aforementioned drawbacks.

Ainsi, un élément de construction selon l'invention, comprend deux parois extérieures longitudinales, à savoir une première paroi extérieure et une seconde paroi extérieure, une paroi interne longitudinale et une séries d'entretoises agencées de manière transversale aux parois, les trois parois sont parallèles et espacées les unes des autres pour créer deux espaces longitudinaux, à savoir un premier espace localisé entre la première paroi extérieure et la paroi interne dans lequel est disposée une série de premières entretoises réparties avec un écartement constant, et un second espace localisé entre la seconde paroi extérieure et la paroi interne dans lequel est disposée une série de seconde entretoises réparties avec un écartement constant, tandis que les écartements des premières entretoises et les écartements des secondes entretoises sont égaux, caractérisé en ce que l'intervalle entre une première entretoise et une seconde entretoise d'un couple d'entretoises est inférieur à la moitié de l'écartement de deux entretoises d'un même espace.Thus, a construction element according to the invention comprises two longitudinal outer walls, namely a first outer wall and a second outer wall, a longitudinal inner wall and a series of spacers arranged transversely to the walls, the three walls are parallel and spaced from each other to create two longitudinal spaces, namely a first space located between the first outer wall and the inner wall in which is disposed a series of first spacers distributed with a constant spacing, and a second space located between the second outer wall and the inner wall in which is arranged a series of second spacers distributed with a constant spacing, while the spacings of the first spacers and the spacings of the second spacers are equal, characterized in that the interval between a first spacer and a second spacer of a pair of spacers is less than half the spacing of two spacers of the same space.

Selon une caractéristique, le rapport entre l'écartement de deux entretoises d'un même espace et l'intervalle entre une première entretoise et une seconde entretoise d'un couple d'entretoises, est compris entre 2,5 et 12, de préférence compris entre 3 et 10.According to one characteristic, the ratio between the spacing of two spacers of the same space and the gap between a first spacer and a second spacer of a pair of spacers is between 2.5 and 12, preferably between between 3 and 10.

Selon une caractéristique complémentaire, l'intervalle entre une première entretoise et une seconde entretoise d'un couple d'entretoises, est inférieur ou égal à 20 fois l'épaisseur de la paroi interne, de préférence compris entre 4 et 12 fois l'épaisseur de la paroi interne.According to a complementary feature, the gap between a first spacer and a second spacer of a pair of spacers is less than or equal to 20 times the thickness of the inner wall, preferably between 4 and 12 times the thickness. of the inner wall.

Notons que l'écartement de deux entretoises d'un même espace est compris entre 25 et 50 fois l'épaisseur de la paroi interne.Note that the spacing of two spacers of the same space is between 25 and 50 times the thickness of the inner wall.

Précisons que l'épaisseur de la paroi interne est comprise entre 20 et 50 millimètres, de préférence comprise entre 21 et 45 millimètres.Note that the thickness of the inner wall is between 20 and 50 millimeters, preferably between 21 and 45 millimeters.

Ainsi, un élément de construction selon l'invention, se présente par une poutre (101) ou un panneau (102), qui comprennent deux parois extérieures (1a, 1b), à savoir une première paroi extérieure (1a) et une seconde paroi extérieure (1b), ainsi qu'une paroi interne (2) et une succession d'entretoises (3a, 3b).Thus, a building element according to the invention, is provided by a beam (101) or a panel (102), which comprise two outer walls (1a, 1b), namely a first outer wall (1a) and a second wall an outer wall (1b) and an inner wall (2) and a succession of spacers (3a, 3b).

Notons que les parois extérieures (1a, 1b) et la paroi interne (2) sont longitudinales.Note that the outer walls (1a, 1b) and the inner wall (2) are longitudinal.

Il est entendu qu'une poutre (101) a un profil longitudinal allongé ayant une hauteur inférieure à celle d'un panneau (102). La longueur et la largeur, à savoir l'épaisseur d'une poutre (101) étant avantageusement égales à celles d'un panneau (102).It is understood that a beam (101) has an elongated longitudinal profile having a height less than that of a panel (102). The length and the width, namely the thickness of a beam (101) being advantageously equal to that of a panel (102).

Une poutre (101) a usuellement une hauteur inférieure à 600 millimètres, tandis qu'un panneau (102) a conventionnellement une hauteur inférieure à 3 000 millimètres.A beam (101) usually has a height of less than 600 millimeters, while a panel (102) conventionally has a height of less than 3,000 millimeters.

Les parois extérieures (1a, 1b), ainsi que la paroi interne (2) sont parallèles, tandis que les entretoises (3a, 3b) sont perpendiculaires aux parois (1a, 1b, 2).The outer walls (1a, 1b) and the inner wall (2) are parallel, while the spacers (3a, 3b) are perpendicular to the walls (1a, 1b, 2).

Les parois extérieures (1a, 1b) sont disposées à une distance l'une de l'autre, de telle manière à ce que la paroi interne (2) soit disposée entre les parois extérieures (1a, 1b), afin de créer un premier espace (4a) entre la première paroi extérieure (1a) et la paroi interne (2) et un second espace (4b) entre la seconde paroi extérieure (1b) et la paroi interne (2).The outer walls (1a, 1b) are arranged at a distance from each other, so that the inner wall (2) is disposed between the outer walls (1a, 1b), to create a first space (4a) between the first outer wall (1a) and the inner wall (2) and a second space (4b) between the second outer wall (1b) and the inner wall (2).

Dans chacun des espaces (4a, 4b) est disposée une série d'entretoises (3a, 3b), à savoir dans le premier espace (4a) est agencée une série de premières entretoises (3a) réparties avec un écartement (E1) constant, à savoir ayant un écartement (E1) constant entre deux premières entretoises (3a) d'une même série localisées dans le premier espace (4a), tandis que dans le second espace (4b) est localisée une série de secondes entretoises (3b) réparties avec un écartement (E1) constant, à savoir un écartement (E1) constant entre deux secondes entretoises (3b) d'une même série localisées dans le second espace (4b).In each of the spaces (4a, 4b) is arranged a series of spacers (3a, 3b), namely in the first space (4a) is arranged a series of first spacers (3a) distributed with a spacing (E1) constant, that is to say having a spacing (E1) constant between two first spacers (3a) of the same series located in the first space (4a), while in the second space (4b) is located a series of second spacers (3b) distributed with a spacing (E1) constant, namely a spacing (E1) constant between two second spacers (3b) of the same series located in the second space (4b).

Précisons que les écartements (E1) entre deux entretoises (3a, 3b) d'un même espace (4a, 4b), à savoir entre deux premières entretoises (3a) et entre deux secondes entretoises (3b), sont égaux.Note that the spacings (E1) between two spacers (3a, 3b) of the same space (4a, 4b), namely between two first spacers (3a) and between two second spacers (3b), are equal.

Notons que la première série d'entretoises (3a) est décalée par rapport à la seconde série d'entretoises (3b), de telle manière à former des couples (5) d'entretoises (3a, 3b), à savoir un couple (5) d'une première entretoise (3a) et d'une seconde entretoise (3b) disposées de manière adjacente dans le premier espace (4a) et le second espace (4b) respectivement.Note that the first series of spacers (3a) is offset relative to the second series of spacers (3b), so as to form pairs (5) of spacers (3a, 3b), namely a pair ( 5) a first spacer (3a) and a second spacer (3b) disposed adjacently in the first space (4a) and the second space (4b) respectively.

Ajoutons que tel qu'illustré à la figure 1, la série de secondes entretoises (3b) est décalée par rapport à la série de première entretoises (3a) d'une distance inférieure à la moitié de l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace.Let's add that as illustrated in figure 1 , the series of second spacers (3b) is offset relative to the series of first spacers (3a) by a distance less than half the spacing (E1) of two spacers (3a, 3b) of the same space .

Il est ainsi entendu que la série de premières entretoises (3a) est décalée par rapport à la série de secondes entretoises (3b) d'une distance inférieure à la moitié de l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b).It is thus understood that the series of first spacers (3a) is offset relative to the series of second spacers (3b) by a distance less than half the spacing (E1) of two spacers (3a, 3b) d the same space (4a, 4b).

En d'autres termes, tel qu'illustré à la figure 2, l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5) d'entretoises (3a, 3b), est inférieur à la moitié de l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b).In other words, as illustrated in figure 2 the interval (E2) between a first spacer (3a) and a second spacer (3b) of a pair (5) of spacers (3a, 3b) is less than half the distance (E1) of two spacers (3a, 3b) of the same space (4a, 4b).

Il est ainsi entendu par un couple (5) d'entretoises (3a, 3b), un couple (5) d'une première entretoise (3a) et d'une seconde entretoise (3b) adjacentes, ayant un intervalle (E2) inférieur à la moitié de l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b).It is thus understood by a pair (5) of spacers (3a, 3b), a pair (5) of a first spacer (3a) and a second spacer (3b) adjacent, having a lower interval (E2) at half the spacing (E1) of two spacers (3a, 3b) of the same space (4a, 4b).

Tel que précisé précédemment, l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5) d'entretoises (3a, 3b), inférieur à la moitié de l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b), correspond à un rapport entre l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b) et l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5), supérieur à 2.As previously specified, the interval (E2) between a first spacer (3a) and a second spacer (3b) of a pair (5) of spacers (3a, 3b), less than half the distance ( E1) of two spacers (3a, 3b) of the same space (4a, 4b), corresponds to a ratio between the spacing (E1) of two spacers (3a, 3b) of the same space (4a, 4b) and the interval (E2) between a first spacer (3a) and a second spacer (3b) of a pair (5), greater than 2.

De préférence, le rapport entre l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b) et l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5) d'entretoises (3a, 3b), est compris entre 2,5 et 12, plus préférentiellement, compris entre 3 et 10, plus préférentiellement entre 4 et 6.Preferably, the ratio between the spacing (E1) of two spacers (3a, 3b) of the same space (4a, 4b) and the interval (E2) between a first spacer (3a) and a second spacer (3b) ) a pair (5) of spacers (3a, 3b) is between 2.5 and 12, more preferably between 3 and 10, more preferably between 4 and 6.

Ajoutons que l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b) est compris entre 600 et 2 000 millimètres, de préférence entre 1 000 et 1400 millimètres, avantageusement égal à 1200 millimètres.Add that the spacing (E1) of two spacers (3a, 3b) of the same space (4a, 4b) is between 600 and 2000 millimeters, preferably between 1000 and 1400 millimeters, preferably equal to 1200 millimeters.

Notons que l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5) d'entretoises (3a, 3b) est compris entre 105 et 1000 de préférence compris entre 105 et 660 millimètres, plus préférentiellement compris entre 200 et 480 millimètres.Note that the interval (E2) between a first spacer (3a) and a second spacer (3b) of a pair (5) of spacers (3a, 3b) is between 105 and 1000, preferably between 105 and 660 millimeters, more preferably between 200 and 480 millimeters.

Les épaisseurs des parois (1a, 1b, 2) sont avantageusement égales. Etant donné que c'est la paroi interne (2) qui est sollicitée lors de l'assemblage sous presse, son épaisseur est un paramètre important pour l'optimisation de la structure de la poutre (101) ou du panneau (102) selon l'invention.The thicknesses of the walls (1a, 1b, 2) are advantageously equal. Since it is the inner wall (2) which is stressed during assembly in press, its thickness is an important parameter for the optimization of the structure of the beam (101) or the panel (102) according to the invention. 'invention.

Selon une caractéristique, l'épaisseur (E3) de la paroi interne est comprise entre 20 et 50 millimètres, de préférence compris entre 21 et 45 millimètres.According to one characteristic, the thickness (E3) of the inner wall is between 20 and 50 millimeters, preferably between 21 and 45 millimeters.

Notons que plus la paroi interne (2) est épaisse et plus l'écartement (E1) de deux entretoises (3a, 3b) d'un même espace (4a, 4b) peut être important.Note that the thicker the inner wall (2) and the greater the spacing (E1) of two spacers (3a, 3b) of the same space (4a, 4b) can be important.

Selon une caractéristique, l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5) d'entretoises (3a, 3b) est inférieur ou égal à 20 fois l'épaisseur (E3) de la paroi interne (2).According to one characteristic, the interval (E2) between a first spacer (3a) and a second spacer (3b) of a pair (5) of spacers (3a, 3b) is less than or equal to 20 times the thickness ( E3) of the inner wall (2).

Selon la caractéristique précédente, l'intervalle (E2) entre une première entretoise (3a) et une seconde entretoise (3b) d'un couple (5) d'entretoises (3a, 3b), est compris entre 4 et 12 fois, de préférence compris entre 5 et 10 fois l'épaisseur (E3) de la paroi interne (2).According to the preceding characteristic, the interval (E2) between a first spacer (3a) and a second spacer (3b) of a pair (5) of spacers (3a, 3b) is between 4 and 12 times, of preferably between 5 and 10 times the thickness (E3) of the inner wall (2).

Selon une caractéristique, les parois (1a, 1b, 2), ainsi qu'avantageusement les entretoises (3a, 3b), sont en matériaux composites constitués de couches de placage de bois, tel qu'en bois lamellé-croisé (CLT : cross-laminated timber) dont les fibres sont orientées perpendiculairement ou en bois déroulé contreplaqué (LVL : laminated veneer lumber) dont les fibres sont orientées dans la même direction ou perpendiculaire.According to one feature, the walls (1a, 1b, 2), and advantageously the spacers (3a, 3b), are made of composite materials consisting of layers of wood veneer, such as cross-laminated wood (CLT: cross -laminated timber) whose fibers are oriented perpendicular or laminated veneer lumber (LVL) whose fibers are oriented in the same direction or perpendicular.

Selon la caractéristique précédente, ces matériaux composites ont la particularité d'avoir une forte stabilité dimensionnelle et de grandes résistances mécaniques. Contrairement au bois massif, ces matériaux permettent que les efforts mécaniques, lors de l'assemblage d'un mur à partir de poutres (101), soient supportés par les parois (1a, 1b, 2) et non par les entretoises (3a, 3b).According to the preceding characteristic, these composite materials have the particularity of having a high dimensional stability and high mechanical strengths. Unlike solid wood, these materials allow the mechanical forces, when assembling a wall from beams (101), are supported by the walls (1a, 1b, 2) and not by the spacers (3a, 3b).

Selon une caractéristique complémentaire, au moins une des extrémités latérales de la poutre (101) ou du panneau (102), comprend un bloc de fermeture cloisonnant une extrémité latérale d'un espace (4a, 4b).According to a complementary feature, at least one of the lateral ends of the beam (101) or the panel (102) comprises a closure block partitioning a lateral end of a space (4a, 4b).

Ajoutons que la poutre (101) ou le panneau (102) selon l'invention, peut comprendre des éléments d'isolation (6) localisés dans les espaces de remplissage (7) agencés entre deux entretoises (3a, 3b) d'un même espace (4a, 4b).Let us add that the beam (101) or the panel (102) according to the invention may comprise insulating elements (6) located in the filling spaces (7) arranged between two spacers (3a, 3b) of the same space (4a, 4b).

Selon une caractéristique, les éléments d'isolation (6) sont des éléments d'isolation fibreux.According to one characteristic, the insulation elements (6) are fibrous insulation elements.

Selon la caractéristique précédente, les éléments d'isolation (6) peuvent être sélectionnés parmi les laines minérales telles que la laine de verre ou la laine de roche, les matériaux isolants issus de l'agriculture, tels que le lin, la chènevotte ou le chanvre, les matériaux isolants à base de bois, tels que le liège expansé ou les fibres de bois souples, les matériaux isolants issus du recyclage, tels que le textile recyclé ou la ouate de cellulose, les matériaux isolants d'origine animale, tels que la laine de mouton ou les plumes de canard.According to the preceding characteristic, the insulating elements (6) can be selected from mineral wools such as glass wool or rock wool, insulating materials derived from agriculture, such as linen, hemp or hemp, wood-based insulation materials, such as expanded cork or softwood fibers, insulation materials derived from recycling, such as recycled textile or cellulose wadding, insulating materials of animal origin, such as sheep's wool or duck feathers.

Les structures particulières des poutres ou panneaux selon l'invention, permettent que les éléments d'isolation contribuent de manière négligeable voire ne participent plus, à la transmission des efforts de pressage lors de l'assemblage, contrairement aux poutres divulguées dans le document FR 3 022 569 .The particular structures of the beams or panels according to the invention allow the insulating elements to contribute negligibly or no longer participate in the transmission of the pressing forces during assembly, unlike the beams disclosed in the document. FR 3,022,569 .

En outre, grâce à la structure particulière d'un élément de construction selon l'invention, il est possible de procéder à un assemblage sous presse à des pressions supérieure à 2,5 bars/cm2, plus précisément des pressions comprises entre 2,5 et 8 bars/cm2, avantageusement à des pressions atteignant 5 bars/cm2.In addition, thanks to the particular structure of a construction element according to the invention, it is possible to proceed to press assembly at pressures greater than 2.5 bar / cm 2, more precisely pressures between 2.5 and 8 bar / cm 2, preferably at pressures up to 5 bar / cm 2.

L'utilisation d'une pression élevée d'assemblage permet d'obtenir une meilleure qualité d'assemblage, en favorisant la qualité du collage.The use of a high assembly pressure makes it possible to obtain a better quality of assembly, by favoring the quality of the bonding.

L'invention concerne également un procédé de fabrication de poutre (101) à partir d'un panneau (102).The invention also relates to a method of manufacturing a beam (101) from a panel (102).
