Le bloc de construction comprend : • un premier panneau et un deuxième panneau, chacun de ces panneaux ayant une surface externe, une surface interne, des bords latéraux, les surfaces externes formant les surfaces apparentes du bloc de construction ; A first aspect of the invention relates to a building block for a tongue-and-groove assembly, with two opposing exposed surfaces and side mating surfaces, some of which include an assembly groove and others include a tongue. assembly nested in the assembly groove. The building block includes: • a first panel and a second panel, each of these panels having an outer surface, an inner surface, side edges, the outer surfaces forming the exposed surfaces of the building block;
• au moins un élément d’espacement et d’assemblage assemblant les deux panneaux en définissant un espacement entre leurs surfaces internes, les surfaces internes des deux panneaux assemblés étant agencées en regard, la rainure d’assemblage le long d’une des surfaces de jointement latérales étant formée par l’espacement entre les surfaces internes en regard des deux panneaux ; et • at least one spacer and assembly element assembling the two panels by defining a spacing between their internal surfaces, the internal surfaces of the two assembled panels being arranged facing each other, the assembly groove along one of the surfaces of lateral joint being formed by the spacing between the facing internal surfaces of the two panels; and
• deux planches en regard formant la languette d’assemblage, chacune de ces deux planches ayant une surface externe, une surface interne et une largeur.• two facing boards forming the assembly tab, each of these two boards having an external surface, an internal surface and a width.
La surface externe d’une première de ces deux planches est fixée sur la surface interne du premier panneau, de façon à ce qu’une partie de sa largeur dépasse d’un premier bord du premier panneau. D’autre part, la surface externe d’une deuxième de ces planches est fixée sur la surface interne du deuxième panneau, de façon à ce qu’une partie de sa largeur dépasse d’un premier bord du deuxième panneau et de telle façon à ce que les surfaces internes des deux planches soient en regard. The outer surface of a first of these two boards is attached to the inner surface of the first panel, so that part of its width protrudes from a first edge of the first panel. On the other hand, the outer surface of a second of these boards is fixed to the inner surface of the second panel, so that part of its width protrudes from a first edge of the second panel and in such a way as to that the internal surfaces of the two boards are facing each other.
[0005] Il sera apprécié que le au moins un élément d’espacement et d’assemblage permet un contrôle de l’espacement entre les panneaux et in fine l’épaisseur du bloc de construction. De plus, l’espacement entre les surfaces internes des deux panneaux peut permettre, p. ex., l’introduction d’un matériau d’isolation thermique et/ ou acoustique dans l’espacement entre leurs surfaces internes du bloc d’assemblage. Dans d’autres applications, p. ex. lorsque les blocs de construction sont utilisés pour former une cloison de séparation d’une zone en travaux en intérieur (pour la sécurité), l’espacement peut être fortement réduit. Le premier aspect de l’invention met ainsi à disposition des blocs de construction ayant une flexibilité accrue par rapport à un système de construction tel que décrit dans le brevet LU 100520. [0005] It will be appreciated that the at least one spacing and assembly element allows control of the spacing between the panels and ultimately the thickness of the building block. In addition, the spacing between the internal surfaces of the two panels may allow, eg. eg, the introduction of a thermal and / or acoustic insulation material in the space between their internal surfaces of the assembly block. In other applications, eg. ex. when building blocks are used to form a partition wall for an indoor working area (for safety), the spacing can be greatly reduced. The first aspect of the invention thus provides building blocks having increased flexibility compared to a building system as described in patent LU 100520.
[0006] Par deux éléments (p. ex. deux planches, deux panneaux) « en regard », on entend que ces deux éléments sont en face l’un de l’autre. En d’autres termes, les deux éléments sont vis-à-vis. [0006] By two elements (eg two boards, two panels) "facing" is meant that these two elements are opposite each other. In other words, the two elements are opposite.
[0007] Par « planche » et « panneaux », on entend des pièces planes, plus longues que larges et peu épaisses. [0008] Selon un mode de réalisation, environ 50% de la largeur des planches dépasse d’un premier bord des panneaux respectifs. Par exemple, entre 40% et 60%, préférablement entre 45% et 55%, encore plus préférablement entre 48% et 52%, de la largeur de la planche dépasse du premier bord des panneaux respectifs. Ce mode de réalisation a l’avantage de mettre à disposition un système d’assemblage à languette et rainure structurellement robuste. By "board" and "panels" is meant flat pieces, longer than they are wide and not very thick. [0008] According to one embodiment, approximately 50% of the width of the boards protrudes from a first edge of the respective panels. For example, between 40% and 60%, preferably between 45% and 55%, even more preferably between 48% and 52%, of the width of the board protrudes from the first edge of the respective panels. This embodiment has the advantage of providing a structurally robust tongue and groove assembly system.
[0009] Selon un mode de réalisation préféré, les surfaces internes des parties des planches qui dépassent des premiers bords des premier et deuxième panneaux sont amincies sur une largeur et une longueur comprise dans l’intervalle allant de 5 à 15 mm, préférablement, de 7 à 12 mm, encore plus préférablement de g 11 mm, à partir des bords des parties de planches qui dépassent. According to a preferred embodiment, the internal surfaces of the parts of the boards which protrude from the first edges of the first and second panels are thinned over a width and a length ranging from 5 to 15 mm, preferably, from 7 to 12 mm, still more preferably 11 mm g, from the edges of the protruding board parts.
[0010] Selon un mode de réalisation préféré, les rainures d’assemblage comprennent des surfaces locales surélevées agencées sur les surface internes des panneaux, les surfaces locales surélevées étant agencées de façon à servir de surfaces d’appui pour les extrémités des languettes d’assemblage d’un deuxième bloc de construction tel que décrit ci-dessus. According to a preferred embodiment, the assembly grooves comprise raised local surfaces arranged on the internal surfaces of the panels, the raised local surfaces being arranged so as to serve as bearing surfaces for the ends of the tongues of. assembly of a second building block as described above.
[0011] Avantageusement, le au moins un élément d’espacement et d’assemblage peut comprendre au moins une planche transversale d’espacement qui est fixée sur les surfaces internes des panneaux. [0011] Advantageously, the at least one spacer and assembly element may include at least one transverse spacer board which is fixed to the internal surfaces of the panels.
[0012] Selon un mode de réalisation, les surfaces internes des panneaux comprennent des renfoncements (mortaises), préférablement fraisés, arrangés de telle façon à ce que leurs surfaces de base soient exactement agencées à une distance d de la surface externe des panneaux respectifs. Les renfoncements peuvent séparer les surfaces locales surélevées, et, ensemble avec celles-ci, structurer les surfaces internes des panneaux. According to one embodiment, the internal surfaces of the panels comprise recesses (mortises), preferably milled, arranged so that their base surfaces are exactly arranged at a distance d from the external surface of the respective panels. The recesses can separate the raised local surfaces, and together with them, structure the internal surfaces of the panels.
[0013] Le au moins un élément d’espacement et d’assemblage peut comprendre au moins deux planches transversales d’espacement agencées en parallèle. [0013] The at least one spacer and assembly element may include at least two transverse spacer boards arranged in parallel.
[0014] Préférablement, les planches comprennent, sur leurs surfaces extérieures, des rainures pour clavette, les rainures étant parallèles au bord du panneau. [0015] Avantageusement, les deux planches sont formées par deux éléments de planche. Préférablement, les deux éléments de planche sont disjoints. Un premier élément de planche comprend essentiellement une rainure pour clavette dans la direction de la longueur de la planche. Un deuxième élément de planche comprend une rainure pour clavette dans la direction de la longueur de la planche et une rainure pour clavette dans la direction de la largeur de la planche, ce deuxième élément de planche étant agencé en angle droit par rapport au premier élément de planche. Preferably, the boards comprise, on their outer surfaces, keyways, the grooves being parallel to the edge of the panel. Advantageously, the two boards are formed by two board elements. Preferably, the two board elements are separate. A first board member essentially comprises a keyway in the direction of the length of the board. A second board member comprises a keyway in the length direction of the board and a keyway in the direction of the width of the board, said second board member being arranged at right angles to the first board member. plank.
[0016] Les panneaux peuvent comprendre, au niveau des rainures d’assemblage, sur leurs surfaces internes, des rainures ou mortaises pour clavette qui sont parallèles au bord du panneau. [0016] The panels can comprise, at the level of the assembly grooves, on their internal surfaces, keyways or mortises which are parallel to the edge of the panel.
[0017] Les bords latéraux des panneaux peuvent comprendre plusieurs languettes et rainures de dimensions millimétriques, agencées de façon à s’emboîter lorsque la languette d’assemblage du bloc s’emboîte dans la rainure d’assemblage d’un deuxième bloc de construction tel que décrit ci-dessus. Ceci à l’avantage de permettre un emboîtement entre les différents panneaux des différentes planches. The side edges of the panels can include several tongues and grooves of millimeter dimensions, arranged so as to fit together when the assembly tongue of the block fits into the assembly groove of a second building block such as as described above. This has the advantage of allowing interlocking between the different panels of the different boards.
[0018] Les panneaux, les planches et/ou éléments d’espacement peuvent être des panneaux, des planches et/ou des éléments d’espacement en bois, en fibrociment et/ou en plastique. [0018] The panels, planks and / or spacers can be panels, planks and / or spacers made of wood, fiber cement and / or plastic.
[0019] Selon un mode de réalisation préféré, les deux panneaux sont agencés en parallèle par le au moins un élément d’espacement et d’assemblage. [0019] According to a preferred embodiment, the two panels are arranged in parallel by the at least one spacer and assembly element.
[0020] Le bloc de construction comprend avantageusement des panneaux et des planches ayant une forme de parallélépipède rectangle. Le bloc comprend alors avantageusement quatre surfaces de joint ement latérales, dont deux de ces surfaces de jointement latérales comprennent des rainures d’assemblage et deux autres de ces surfaces de jointement latérales comprennent des languettes d’assemblage, aptes à former un joint avec au moins un bloc de construction adjacent ayant les même quatre surfaces de jointement latérales. Il est cependant à noter qu’il n’est pas exclu d’utiliser des éléments de construction ayant une autre forme qu’un parallélépipède rectangle et/ou un autre nombre ou agencement de surfaces de jointement équipées de languettes et/ou rainures. [0021] L’ensemble panneau et planche pourrait être formé de façon monolithique, p. ex. par moulage lorsque ceux-ci sont en plastique. D’autre part, il n’est pas exclu que les différents panneaux, planches et au moins un élément d’espacement et d’assemblage soient formés à partir de matériaux différents. The building block advantageously comprises panels and boards having the shape of a rectangular parallelepiped. The block then advantageously comprises four lateral joining surfaces, of which two of these lateral joining surfaces comprise assembly grooves and two others of these lateral joining surfaces comprise assembly tongues, capable of forming a seal with at least an adjacent building block having the same four side mating surfaces. It should be noted, however, that it is not excluded to use construction elements having a shape other than a rectangular parallelepiped and / or another number or arrangement of joining surfaces equipped with tongues and / or grooves. The panel and board assembly could be formed monolithically, p. ex. by molding when these are made of plastic. On the other hand, it is not excluded that the different panels, boards and at least one spacer and assembly element are formed from different materials.
[0022] Un second aspect de l’invention concerne un procédé de fabrication d’un bloc de construction tel que décrit ci-dessus, comprenant : [0022] A second aspect of the invention relates to a method of manufacturing a building block as described above, comprising:
• la production, p. ex. l’usinage, des panneaux et des planches ; • production, p. ex. machining, panels and planks;
• la fixation des planches aux panneaux ; • fixing the boards to the panels;
• le stockage des planches et des panneaux ainsi produits ; • storage of boards and panels produced in this way;
• la production du au moins un élément d’espacement selon une épaisseur de blocs commandés ; et • the production of at least one spacer according to a thickness of ordered blocks; and
• l’assemblage du bloc commandé en utilisant les pièces stockées et les éléments d’espacement produits sur mesure, de telle façon à produire un bloc ayant l’épaisseur commandée. • assembly of the ordered block using stored parts and custom produced spacers, so as to produce a block of the ordered thickness.
[0023] Il sera apprécié que la structure d’un bloc de construction tel que décrit ci-dessus permet à celui-ci d’être fabriqué à la demande, et ainsi, p. ex. de réduire l’espace requis pour le stockage avant vente. En effet, il est possible de produire et fixer les différent panneaux et planches qui formeront le bloc en avance. Les panneaux et planches peuvent alors être stockés dans un entrepôt en attente d’une commande de bloc de construction. Selon les besoins en épaisseur pour la commande, les éléments d’espacement peuvent être produits et les blocs assemblés et envoyés au destinataire. [0023] It will be appreciated that the structure of a building block as described above allows it to be made to order, and thus, p. ex. reduce the space required for pre-sales storage. Indeed, it is possible to produce and fix the different panels and boards that will form the block in advance. The panels and planks can then be stored in a warehouse pending a building block order. Depending on the thickness requirements for the order, spacers can be produced and the blocks assembled and sent to the recipient.

Description détaillée d’un mode de réalisation de l’invention Detailed description of an embodiment of the invention
[0026] La Fig. 1 illustre un bloc de construction 10 pour un assemblage à languette et rainure selon un mode de réalisation préféré de l’invention. Le bloc 10 comprend des surfaces de jointement latérales, décrites ci-après, permettant l’interconnexion du bloc de construction 10 avec un autre bloc de construction selon le mode de réalisation préféré de l’invention. Le bloc 10 comprend un premier panneau 12 et un deuxième panneau 14, chacun de ces panneaux ayant une surface externe 16, une surface interne 18, des bords latéraux 20. Les deux panneaux sont fixés par des éléments d’espacement et d’assemblage 22 de telle façon à ce que les surfaces internes 18 des deux panneaux 12, 14 assemblés soient agencées en regard. Les surfaces externes 16 forment alors les surfaces apparentes du bloc de construction 10. Les éléments 22 créent un espacement entre les surfaces internes 18 des deux panneaux 12, 14. Le bloc de construction comprend, en plus, une première planche 24 et une deuxième planche 26, chacune de ces deux planches 24, 26 ayant une surface externe 28, une surface interne 30. Une partie de la surface externe 28 de chacune ces deux planches est fixée sur la surface interne 18 des deux panneaux 12, 14 respectifs, tel que représenté à la Fig. 1. Les parties qui dépassent des planches 24, 26 forment ainsi des languettes d’assemblage. [0026] FIG. 1 illustrates a building block 10 for a tongue and groove assembly according to a preferred embodiment of the invention. Block 10 includes side mating surfaces, described below, permitting interconnection of building block 10 with another building block according to the preferred embodiment of the invention. Block 10 comprises a first panel 12 and a second panel 14, each of these panels having an outer surface 16, an inner surface 18, side edges 20. The two panels are secured by spacers and joints 22. so that the internal surfaces 18 of the two assembled panels 12, 14 are arranged facing each other. The outer surfaces 16 then form the exposed surfaces of the building block 10. The elements 22 create a spacing between the internal surfaces 18 of the two panels 12, 14. The building block further comprises a first board 24 and a second board. 26, each of these two boards 24, 26 having an external surface 28, an internal surface 30. A part of the external surface 28 of each of these two boards is fixed on the internal surface 18. of the two respective panels 12, 14, as shown in FIG. 1. The parts which protrude from the boards 24, 26 thus form assembly tongues.
[0027] Selon un mode de réalisation préféré, les panneaux 12, 14, les planches 24, 26 et les éléments 22 sont des parallélépipèdes rectangles. D’autres formes sont évidemment aussi contemplées, selon les besoins et applications. Les panneaux 12, 14, les planches 24, 26 et les éléments 22 peuvent aussi avoir des formes différentes. Il est possible de concevoir que les surface apparentes comprennent un motif et/ou un relief de telle façon à les rendre le bloc décoratif. According to a preferred embodiment, the panels 12, 14, the boards 24, 26 and the elements 22 are rectangular parallelepipeds. Other forms are obviously also contemplated, depending on needs and applications. The panels 12, 14, the boards 24, 26 and the elements 22 can also have different shapes. It is possible to conceive that the visible surfaces comprise a pattern and / or a relief in such a way as to make them the decorative block.
[0028] Selon le mode de réalisation préféré, les planches 24, 26 sont chacune formées par un premier élément de planche 32 et un deuxième élément de planche 34. Le premier élément de planche 32 comprend essentiellement une rainure 36 pour clavette dans la direction de la longueur LPi de la planche. Le deuxième élément de planche 34 comprend une rainure 38 pour clavette dans la direction de la longueur Lp2 de la planche et une rainure 40 pour clavette dans la direction de la largeur lp2 de la planche. Les rainures sont avantageusement parallèles à au moins un des bords du panneau. La rainure 40 du deuxième élément de planche 34 est avantageusement alignée avec la rainure 36 du premier élément de planche 32 de telle façon à ce que lorsque le deuxième élément de planche 34 est agencé en angle droit par rapport au premier élément de planche 32, ces deux rainures forment une rainure continue 36, 40. Avantageusement les dimensions de ces rainures sont similaires (c.-à-d. à une tolérance de 10%), voire identiques (c.-à- d. à une tolérance de 1%). Selon un mode de réalisation, les planches 32, 34 ne sont pas formées par deux éléments 30, 32 de planche mais sont formées de façon monolithique. According to the preferred embodiment, the boards 24, 26 are each formed by a first board member 32 and a second board member 34. The first board member 32 essentially comprises a keyway 36 in the direction of the length L Pi of the board. The second board member 34 includes a keyway 38 in the direction of the length L p2 of the board and a keyway 40 in the direction of the width l p2 of the board. The grooves are advantageously parallel to at least one of the edges of the panel. The groove 40 of the second board member 34 is advantageously aligned with the groove 36 of the first board member 32 such that when the second board member 34 is arranged at right angles to the first board member 32, these two grooves form a continuous groove 36, 40. Advantageously the dimensions of these grooves are similar (ie at a tolerance of 10%), or even identical (ie at a tolerance of 1% ). According to one embodiment, the boards 32, 34 are not formed by two board elements 30, 32 but are formed monolithically.
[0029] Comme indiqué plus haut, les planches 24, 26 sont fixées aux panneaux 12, 14. En particulier, le premier élément de planche 32 est fixé de telle façon à ce qu’environ 50% de sa largeur dépasse d’un premier bord du panneau. D’autre part, le deuxième élément de planche 34 est fixé de telle façon à ce qu’environ 50% de sa largeur dépasse d’un deuxième bord du panneau. Lesdits premier bord et second bord du panneau se rencontrent sur un coin du panneau. Les planches 32, 34 sont ainsi adjacentes. Tel qu’illustré à la Fig. 1, les différentes rainures des planches 32, 34 sont arrangés dans la partie qui dépasse des panneaux 12, 14. [0030] D’autre part, les panneaux 12, 14 comprennent, au niveau des rainures d’assemblage, sur leurs surfaces internes 18, des rainures ou mortaises 42 pour clavette qui sont parallèles au bord du panneau. Ces rainures ou mortaises 42 sont arrangées de telle façon à être en regard avec les rainures 36, 38, 40 des planches 32, 34. Ainsi, lorsque plusieurs blocs sont interconnectés, des espaces interstitiels sont formés pour insertion de clavette. Les différents blocs de construction 10 sont rendus solidaires par l’insertion de clavettes dans les espaces interstitiels. Par exemple, une clavette telle que divulguée dans le brevet LU 100520 pourrait convenir. As indicated above, the boards 24, 26 are fixed to the panels 12, 14. In particular, the first board member 32 is fixed so that approximately 50% of its width exceeds a first edge of the panel. On the other hand, the second board member 34 is fixed so that about 50% of its width protrudes from a second edge of the panel. Said first edge and second edge of the panel meet at a corner of the panel. The boards 32, 34 are thus adjacent. As shown in Fig. 1, the different grooves of the boards 32, 34 are arranged in the part which protrudes from the panels 12, 14. On the other hand, the panels 12, 14 comprise, at the level of the assembly grooves, on their internal surfaces 18, grooves or mortises 42 for a key which are parallel to the edge of the panel. These grooves or mortises 42 are arranged so as to face the grooves 36, 38, 40 of the boards 32, 34. Thus, when several blocks are interconnected, interstitial spaces are formed for key insertion. The various building blocks 10 are made integral by the insertion of keys in the interstitial spaces. For example, a key such as disclosed in patent LU 100520 could be suitable.
[0031] Selon un mode de réalisation, les bords latéraux 20 des panneaux 12, 14 peuvent comprendre une pluralité de languettes et rainures de dimensions millimétriques (non représenté sur les Figs. 1-3, 5, 6). Cette pluralité de languettes et rainures de dimensions millimétriques est agencée sur les bords latéraux 20 de telle façon à s’emboîter lorsque la languette d’assemblage du bloc 10 s’emboîte dans la rainure d’assemblage d’un deuxième bloc de construction selon ledit mode de réalisation. La Fig. 4 représente une vue en coupe d’un panneau (12 ou 14) montrant la pluralité de languettes et rainures de dimensions millimétriques 43 arrangée sur les bords latéraux 20. According to one embodiment, the side edges 20 of the panels 12, 14 can comprise a plurality of tongues and grooves of millimeter dimensions (not shown in Figs. 1-3, 5, 6). This plurality of tongues and grooves of millimeter dimensions is arranged on the side edges 20 so as to fit together when the assembly tongue of the block 10 fits into the assembly groove of a second building block according to said assembly. embodiment. Fig. 4 is a sectional view of a panel (12 or 14) showing the plurality of tongues and grooves of millimeter dimensions 43 arranged on the side edges 20.
[0032] La Fig. 2 est un agrandissement d’une partie de la Fig. 1 représentant une partie du panneau 12 et des planches 32, 34 du bloc de construction 10 selon le mode de réalisation préféré de l’invention. Tel que représenté à la Fig. 2, les surfaces externes 28 des parties des planches 24, 26 qui dépassent panneaux 12, 14 sont amincies sur une largeur la, respectivement une longueur La, comprise dans l’intervalle allant de 5 à 15 mm à partir des bords des parties de planches qui dépassent. En particulier, l’élément de planche 32 est aminci sur une largeur La. L’élément de planche 34 est aminci à la fois sur une largeur la et une longueur La. Il s’ensuit que des surfaces d’appui sont créées sur les surfaces externes 28 à une distance la, respectivement La, des bords des parties de planches qui dépassent. De plus, avec référence à la Fig. 3, les rainures d’assemblage comprennent des surfaces locales surélevées 44 agencées sur les surfaces internes 18 des panneaux 14. Une partie des surfaces locales surélevées 44 sont agencées de façon à servir de surfaces d’appui pour les extrémités des languettes d’assemblage d’un deuxième bloc de construction comprenant des planches 24, 26 avec des surfaces externes 28 amincies telles que décrites ci-dessus. Avantageusement, les surfaces d’appui sont localisées à une distance la et/ ou La du bord des panneaux 12, 14 afin de coopérer avec, plus particulièrement s’appuyer sur, les surfaces d’appui des planches 24, 26 d’un autre bloc. Préférablement, les distances la et La sont identiques. [0032] FIG. 2 is an enlargement of part of FIG. 1 showing part of panel 12 and boards 32, 34 of building block 10 according to the preferred embodiment of the invention. As shown in FIG. 2, the outer surfaces 28 of the parts of the boards 24, 26 which protrude from the panels 12, 14 are thinned over a width l a , respectively a length L a , within the range of 5 to 15 mm from the edges of the parts of boards protruding. In particular, the plank element 32 is thinned over a width L a . The plank member 34 is thinned over both a width l a and a length L a . As a result, bearing surfaces are created on the outer surfaces 28 at a distance l a , respectively L a , from the edges of the protruding board parts. In addition, with reference to FIG. 3, the assembly grooves comprise raised local surfaces 44 arranged on the internal surfaces 18 of the panels 14. A part of the raised local surfaces 44 are arranged to serve as bearing surfaces for the ends of the assembly tongues d. 'a second building block comprising planks 24, 26 with outer surfaces 28 thinned as described above. Advantageously, the bearing surfaces are located at a distance la and / or L a from the edge of the panels 12, 14 in order to cooperate with, more particularly to rest on, the bearing surfaces of the boards 24, 26 of a other block. Preferably, the distances la and L a are identical.
[0033] Avec référence aux Figs. 1 et 3, les éléments d’espacement et d’assemblage 22 sont arrangés perpendiculairement aux surfaces internes 18 et entre les deux panneaux 12, 14. Les éléments d’espacement et d’assemblage 22 sont fixés sur les surfaces internes 18 des panneaux 12, 14. Des renfoncements (mortaises) 46 fraisés sont arrangés sur la surface interne 18 des panneaux 12, 14. Les renfoncements 46 sont arrangés de telle façon à ce que leurs surfaces de base soient exactement agencées à une distance d de la surface externe des panneaux. Les éléments d’espacement et d’assemblage 22 sont fixés sur les surfaces de base des renfoncements. Il s’ensuit qu’il est possible de précisément contrôler l’épaisseur totale des blocs de construction 10 au travers du contrôle de la distance d ainsi que l’espacement introduit par les éléments d’espacement et d’assemblage. Idéalement, les panneaux 12, 14 sont arrangés de façon parallèle après fixation des éléments d’espacement et d’assemblage 22. With reference to Figs. 1 and 3, the spacer and assembly elements 22 are arranged perpendicular to the internal surfaces 18 and between the two panels 12, 14. The spacer and assembly elements 22 are fixed to the internal surfaces 18 of the panels 12. , 14. Countersunk recesses 46 are arranged on the inner surface 18 of the panels 12, 14. The recesses 46 are arranged such that their base surfaces are exactly arranged at a distance d from the outer surface of the panels. panels. The spacers and connections 22 are attached to the base surfaces of the recesses. It follows that it is possible to precisely control the total thickness of the building blocks 10 through the control of the distance d as well as the spacing introduced by the spacers and joints. Ideally, the panels 12, 14 are arranged in parallel after attachment of the spacers and joints 22.
[0034] En d’autres mots, les surfaces internes 18 des panneaux 12 et 14 sont structurées par les renfoncements 46 (et les surfaces locales surélevées 44). L’ensemble des renfoncements peut former une surface continue ou en plusieurs parties séparées. Les éléments d’espacement et d’assemblage 22 sont assemblés aux panneaux 12, 14 sur les surfaces de base des mortaises 46. Des méthodes de production des renfoncements 46 autres que le fraisage sont aussi envisagées, telles que le rabotage, le défonçage, etc. Le contrôle localisé au niveau des enfoncements de la distance d permet de relâcher la contrainte de précision sur l’épaisseur des panneaux 12, 14 mis à disposition pour la fabrication d’un bloc de construction. En d’autres mots, l’épaisseur globale d’un bloc de construction 10 peut être maîtrisé avec une très grande précision grâce au contrôle de la distance d (c.-à-d. la profondeur des enfoncements, qui peut être ajustée individuellement pour chaque panneau 12, 14 en fonction de l’épaisseur réelle de celui-ci) et de la profondeur des éléments d’espacement et d’assemblage 22. En pratique, on pourra dès lors compenser des variations de l’épaisseur des panneaux 12, 14 (dues à des tolérances élevées définies par les producteurs) par le contrôle de la distance d, ce qui permet de réaliser des murs, cloisons, façades etc. très plans et lisses. A l’œil ou au toucher, l’utilisateur ne sentira pas de saillie ou de retrait aux jointures entre les blocs de construction îo. Ceci facilite de manière notable les travaux de finition. In other words, the internal surfaces 18 of the panels 12 and 14 are structured by the recesses 46 (and the raised local surfaces 44). The set of recesses can form a continuous surface or in several separate parts. The spacers and joints 22 are joined to the panels 12, 14 on the base surfaces of the mortises 46. Methods of producing the recesses 46 other than milling are also contemplated, such as planing, routing, etc. . The localized control at the level of the indentations of the distance d makes it possible to relax the precision constraint on the thickness of the panels 12, 14 made available for the manufacture of a building block. In other words, the overall thickness of a building block 10 can be controlled with great precision by controlling the distance d (i.e. the depth of the indentations, which can be individually adjusted. for each panel 12, 14 as a function of the actual thickness thereof) and of the depth of the spacing and assembly elements 22. In practice, it is therefore possible to compensate for variations in the thickness of the panels 12. , 14 (due to high tolerances defined by the producers) by the control of the distance d, which allows to make walls, partitions, facades etc. very flat and smooth. By eye or touch, the user will not feel any protrusion or indentation at the joints between the building blocks. This significantly facilitates the finishing work.
[0035] Selon un mode de réalisation préféré, certains des éléments d’espacement et d’assemblage 22 sont fixés de façon à s’étendre essentiellement le long de la longueur du panneau et d’autres éléments d’espacement et d’assemblage 22 sont fixés de façon à s’étendre essentiellement le long de la largeur du panneau. Avantageusement, les éléments d’espacement et d’assemblage 22 s’étendant essentiellement le long de la longueur du panneau sont agencés côte-à- côte, en contact, avec les éléments d’espacement et d’assemblage 22 s’étendant essentiellement le long de la largeur du panneau de telle façon à rendre les blocs structurellement plus robustes vis-à-vis d’un cisaillement du bloc. Un exemple d’une telle configuration est donné à la Fig. 1, où trois éléments d’espacement et d’assemblage 22 s’étendent essentiellement sur la largeur du panneau et 11 éléments d’espacement et d’assemblage 22 s’étendent essentiellement sur la longueur du panneau. Selon un mode de réalisation préféré, les éléments s’étendant essentiellement le long de la longueur du panneau sont arrangés perpendiculairement aux éléments s’étendant essentiellement le long de la largeur du panneau. [0035] According to a preferred embodiment, some of the spacer and assembly elements 22 are fixed so as to extend essentially along the length of the panel and other spacer and assembly elements 22 are attached so as to extend substantially along the width of the panel. Advantageously, the spacer and assembly members 22 extending substantially along the length of the panel are arranged side by side, in contact, with the spacer and assembly members 22 extending substantially the length of the panel. along the width of the panel so as to make the blocks structurally more robust to shear of the block. An example of such a configuration is given in Fig. 1, where three spacers 22 extend substantially the width of the panel and 11 spacers 22 extend substantially the length of the panel. In a preferred embodiment, the elements extending substantially along the length of the panel are arranged perpendicular to the elements extending substantially along the width of the panel.
[0036] Lors du montage des éléments d’espacement et d’assemblage 22, les renfoncements 46 peuvent aussi faire office de guide pour le placement des éléments 22 sur les panneaux. Dans ce cas, les renfoncements 46 sont dimensionnés en de telle façon à ce que l’entièreté de la surface latérale des éléments 22 touche la surface de base des renfoncements 46 et à ce que la largeur du renfoncement est identique à l’épaisseur des éléments 22. [0036] When mounting the spacing and assembly elements 22, the recesses 46 can also act as a guide for the placement of the elements 22 on the panels. In this case, the recesses 46 are dimensioned in such a way that the entire side surface of the elements 22 touches the base surface of the recesses 46 and that the width of the recess is the same as the thickness of the elements. 22.
[0037] De manière alternative, les renfoncements peuvent être dimensionnés de sorte à ce qu’il y ait du jeu pour le placement des éléments 22 et/ou pour permettre des variations de l’épaisseur de ces pièces (dans la plage de tolérance définie par leur producteur). Alternatively, the recesses can be sized so that there is play for the placement of the elements 22 and / or to allow variations in the thickness of these parts (within the defined tolerance range by their producer).
[0038] Il est à noter que les panneaux, les planches et/ou éléments d’espacement sont des panneaux, des planches et/ou des éléments d’espacement en bois, en fibrociment et/ou en plastique. Préférablement, ces derniers sont en bois. [0039] D’autre part, la fixation des planches 24, 26 aux panneaux 12,14, des éléments d’espacement et d’assemblage 22 aux panneaux 12,14 peut se faire par colle ou par insertion d’un ou plusieurs goujons dans les planches, panneaux et/ ou éléments d’espacement et d’assemblage. Par exemple, dans le mode de réalisation préféré illustré aux Figs. 1-3, des trous 48 pour goujon sont arrangés sur la surface de base des renfoncements 46. D’autre part, des trous 48 pour goujon sont aussi arrangés sur les surfaces latérales des éléments d’espacement et d’assemblage 22. La Fig. 1 représente la situation où les goujons 50 sont déjà insérés dans les trous arrangés sur les surfaces latérales des éléments d’espacement et d’assemblage 22. Comme illustré aux Figs. 4, 5, les panneaux 12, 14 peuvent être fixés aux planches 24 avec des goujons insérés dans des trous 48 pour goujons arrangés sur la surface interne des panneaux 12, 14 et la surface externe des planches 24, 26. It should be noted that the panels, planks and / or spacers are panels, planks and / or spacers made of wood, fiber cement and / or plastic. Preferably, the latter are made of wood. On the other hand, the fixing of the boards 24, 26 to the panels 12,14, the spacing and assembly elements 22 to the panels 12,14 can be done by glue or by inserting one or more studs in planks, panels and / or spacers and assemblies. For example, in the preferred embodiment illustrated in Figs. 1-3, dowel holes 48 are arranged on the base surface of the recesses 46. On the other hand, dowel holes 48 are also arranged on the side surfaces of the spacer and joint members 22. FIG. . 1 shows the situation where the studs 50 are already inserted into the holes arranged on the side surfaces of the spacer and assembly members 22. As illustrated in Figs. 4, 5, panels 12, 14 can be attached to boards 24 with studs inserted into stud holes 48 arranged on the inner surface of panels 12, 14 and the outer surface of boards 24, 26.
[0040] Il est aussi possible de réaliser la fixation par l’utilisation de goujons et de colle. L’utilisation de vis et/ou de clous pour réaliser la fixation n’est pas exclue, mais l’utilisation de goujons et/ou de colle est préférée. [0040] It is also possible to achieve the fixing by the use of studs and glue. The use of screws and / or nails to achieve the fastening is not excluded, but the use of studs and / or glue is preferred.

[0042] Alternativement, il est aussi possible de fixer les planches aux panneaux après réception de la commande. De cette façon, il est possible d’encore diminuer l’espace de stockage nécessaire. [0042] Alternatively, it is also possible to fix the boards to the panels after receipt of the order. In this way, it is possible to further reduce the storage space required.
[0043] La production des panneaux et planches comprend la structuration des panneaux et des planches, p. ex. le fraisage des renfoncements sur la surface interne des panneaux, l’usinage des rainures pour clavette sur les éléments de planche, l’arrangement (p. ex. par forage) de trous pour goujon sur les surfaces des panneaux, planches, etc. The production of panels and planks includes structuring of panels and planks, p. ex. the milling of the recesses on the internal surface of the panels, the machining of the keyways on the elements of board, the arrangement (e.g. by drilling) of dowel holes on the surfaces of panels, boards, etc.
[0044] Il est à noter qu’il est possible de produire des éléments d’espacement selon plusieurs épaisseurs typiques dans le domaine de la construction de telle façon à ce que la production puisse se faire en une fois et qu’il ne reste qu’à assembler les éléments d’espacement après réception de la commande. It should be noted that it is possible to produce spacers in several thicknesses typical in the field of construction so that the production can be done in one go and that only remains '' to assemble the spacers after receipt of the order.
