Description

La présente invention concerne un système de construction modulaire pour la réalisation de structures d'habitation ou de bureau, voire de locaux techniques.The present invention relates to a modular construction system for creating residential or office structures, or even technical premises.

L'auto construction à ossature bois reçoit un engouement de plus en plus favorable par les particuliers.Self-construction with a wooden frame is becoming increasingly popular among individuals.

La volonté de construire à des prix moins élevés sans passer par des professionnels, ou tout du moins en limitant l'intervention de professionnels, en se procurant uniquement le matériel de construction, permet notamment à des primo accédant de pouvoir accéder à la propriété.The desire to build at lower prices without using professionals, or at least by limiting the intervention of professionals, by only purchasing construction equipment, allows first-time buyers in particular to be able to access property.

L'auto construction limite l'investissement de départ et favorise l'obtention d'emprunt auprès des organismes financiers.Self-construction limits the initial investment and encourages obtaining loans from financial organizations.

Ce mode de construction est également plébiscité par des artisans répondant aux demandes de leurs clients exigeant une habitation écoresponsable employant des matières nobles.This method of construction is also popular with craftsmen responding to the demands of their clients requiring eco-responsible housing using noble materials.

La construction d'un ouvrage en bois est moins contraignante qu'une construction en béton ou en parpaings et nécessite l'intervention de moins de corps de métier. L'assemblage d'éléments structurels en bois est ainsi plus accessible techniquement. Cependant, bien que l'offre de kit de construction à ossature bois est en plein développement, la majorité de ces offres consistent en l'empilement de madrier ou de panneaux de grande dimension, nécessitant en général l'installation préalable de moyen de levage conséquents et le recours à des découpes inévitables.The construction of a wooden structure is less restrictive than a concrete or concrete block construction and requires the intervention of fewer trades. The assembly of structural wooden elements is thus more technically accessible. However, although the offer of wooden frame construction kits is in full development, the majority of these offers consist of the stacking of large planks or panels, generally requiring the prior installation of substantial lifting means. and the use of unavoidable cuts.

Une place importante est encore disponible pour faciliter la tâche des auto-constructeurs et favoriser les indécis à se lancer dans ces projets passionnants.An important place is still available to facilitate the task of self-builders and encourage the undecided to embark on these exciting projects.

Malgré ses qualités indéniables, le bois possède quelques inconvénients. Le bois est un matériau hygroscopique, qui peut absorber et rejeter de l'eau selon son environnement et les variations de son taux d'humidité le font se déformer. Les déformations sont fréquentes, notamment pour les éléments extérieurs, exposés aux changements de température et d'humidité.Despite its undeniable qualities, wood has some disadvantages. Wood is a hygroscopic material, which can absorb and release water depending on its environment and variations in its humidity level cause it to deform. Deformations are common, especially for exterior elements, exposed to changes in temperature and humidity.

La facilité d'assemblage d'éléments en bois usinés, dépend également de la précision des découpes de chacun des éléments lors de leur usinage. Des tolérances de dimensionnement sont inévitables. Le document FR3073870 divulgue un système de construction modulaire comprenant toutes les caractéristiques du préambule de la revendication 1.The ease of assembly of machined wooden elements also depends on the precision of the cuts of each of the elements during their machining.

Ainsi, le système de construction modulaire (1) à ossature bois selon l'invention, se présente par une pluralité de profilés de bois de différentes dimensions équipés de moyens de connexion par coopération de forme, qui sont destinées à être assemblées avec des moyens de fixation complémentaires, avantageusement à l'aide d'un simple maillet.Thus, the modular construction system (1) with wooden frame according to the invention, is presented by a plurality of wooden profiles of different dimensions equipped with means of connection by shape cooperation, which are intended to be assembled with means of additional fixing, advantageously using a simple mallet.

Le système de construction modulaire (1) comprend notamment une lisse basse (2), des structures de poutre (3) et des languettes (4).The modular construction system (1) notably comprises a lower rail (2), beam structures (3) and tongues (4).

Précisons qu'une structure de poutre (3) comprend des panneaux (5) assemblés à des entretoises (6), telle que décrit plus en détail dans la suite de la description.Let us specify that a beam structure (3) comprises panels (5) assembled with spacers (6), as described in more detail in the remainder of the description.

Les éléments structurels précités ont un dimensionnement adapté à ce qu'ils puissent être empilés sur une palette, afin de faciliter la livraison sur un chantier de construction, et être assemblés par un artisan voire un particulier.The aforementioned structural elements have a dimension adapted to enable them to be stacked on a pallet, in order to facilitate delivery to a construction site, and to be assembled by a craftsman or even an individual.

Ainsi les éléments structurels précités se présentent par des portions d'éléments structurels à assembler sur site.Thus the aforementioned structural elements are presented as portions of structural elements to be assembled on site.

Les profilés de bois ont des profils sensiblement parallélépipédiques, se présentant sous la forme de planche, dont leurs tranches voire leurs surfaces, comprennent avantageusement différentes rainures, des dégagements voire des trous borgnes.The wooden profiles have substantially parallelepiped profiles, in the form of a board, whose edges or even their surfaces advantageously include different grooves, clearances or even blind holes.

Une languette (4) est un profilé de bois jouant le rôle de tenon dans un assemblage à rainure et languette, destinée à être assemblée à une première rainure (7) de la lisse basse (2) et à seconde rainure (8) d'un panneau (5) d'une structure de poutre (3), en tant que mortaise, telle qu'explicitée plus en détail dans la suite de la description.A tongue (4) is a wooden profile acting as a tenon in a tongue and groove assembly, intended to be assembled to a first groove (7) of the bottom rail (2) and to a second groove (8) of a panel (5) of a beam structure (3), as a mortise, as explained in more detail in the remainder of the description.

Une lisse basse (2) est composée deux types de portions de lisse basse assemblées les unes aux autres, à savoir une portion d'angle (2a) et une portion qu'on qualifiera de droite (2b).A lower rail (2) is made up of two types of lower rail portions assembled together, namely a corner portion (2a) and a portion which will be described as straight (2b).

Rappelons qu'une lisse basse (2) est destinée à être solidarisée par des encrages à une base, telle qu'une plateforme en bois ou une dalle en béton. La lisse basse (2) assurant le lien structurel entre la base et les structures de poutre (3), ainsi que la toiture.Remember that a low rail (2) is intended to be secured by anchors to a base, such as a wooden platform or a concrete slab. The bottom rail (2) ensuring the structural link between the base and the beam structures (3), as well as the roof.

La lisse basse (2) assure d'une manière conventionnelle, l'étanchéité à l'eau, à l'air et une protection contre les remontées capillaires, par l'intermédiaire d'une bande d'arase, non représentée.The lower rail (2) ensures, in a conventional manner, watertightness, airtightness and protection against capillary rise, via a leveling strip, not shown.

Les portions de lisse basse (2a, 2b) ont des profils sensiblement parallélépipédiques voire ayant des faces biseautées ou tronquées, et comprennent deux faces de base et quatre faces latérales.The lower rail portions (2a, 2b) have substantially parallelepiped profiles or even have beveled or truncated faces, and comprise two base faces and four lateral faces.

Une lisse basse (2) étant destinée à être posée sur une base, on qualifiera ainsi les faces de base en tant que face inférieure (21) et face supérieure (22), et les faces latérales en tant que face intérieure (23) destinée à être positionnée à l'intérieur de la structure et face extérieure (24) destinée à être positionnée à l'extérieur de la structure et face d'accouplement (25, 25') destinée à la connexion de deux portions de lisse basse (2a, 2b) l'une avec l'autre dans le sens de la longueur.A low rail (2) being intended to be placed on a base, we will thus qualify the base faces as lower face (21) and upper face (22), and the side faces as inner face (23) intended to be positioned inside the structure and exterior face (24) intended to be positioned outside the structure and coupling face (25, 25') intended for the connection of two lower rail portions (2a , 2b) with each other lengthwise.

Notons que les arrêtes supérieures de la face intérieure (21) et de la face extérieure (24) d'une portion de lisse basse (2a, 2b) sont biseautées, à savoir forment un profil adapté à la fixation d'une baguette de protection, non représentée.Note that the upper edges of the inner face (21) and the outer face (24) of a portion of lower rail (2a, 2b) are beveled, i.e. form a profile suitable for fixing a protective strip , not shown.

Notons également que la lisse basse (2) comprend des dégagements (9) localisés en regard de sa face intérieure (23) dans l'épaisseur de la lisse basse (2) débouchant vers l'intérieur et vers la face supérieure (22). Un dégagement (9) est destiné à la fixation d'une équerre (10) solidarisant la base avec le premier rang d'un assemblage de structures de poutre (3), tel qu'explicité plus en détail dans la suite de la description. Précisons que les portions droites (2b) de la lisse basse (2), comprennent deux faces latérales parallèles deux à deux, à savoir une face intérieure (23) parallèle à une face extérieure (24), ainsi qu'une face d'accouplement (25) parallèle à l'autre face d'accouplement (25).Note also that the lower rail (2) includes clearances (9) located opposite its inner face (23) in the thickness of the lower rail (2) opening towards the inside and towards the upper face (22). A clearance (9) is intended for fixing a bracket (10) securing the base with the first row of an assembly of beam structures (3), as explained in more detail in the remainder of the description. Let us specify that the straight portions (2b) of the lower rail (2), comprise two parallel lateral faces in pairs, namely an interior face (23) parallel to an exterior face (24), as well as a coupling face (25) parallel to the other mating face (25).

Les portions d'angle (2a) de la lisse basse (2), telles qu'illustrées aux figures 2 et 3, comprennent une face intérieure (23) plus courte que la face extérieure (24) agencée en opposition.The corner portions (2a) of the lower rail (2), as illustrated in figures 2 and 3 , comprise an inner face (23) shorter than the outer face (24) arranged in opposition.

Selon le mode de réalisation illustré, la première face d'accouplement (25'), d'une première portion d'angle (2a) destinée à former la moitié d'un angle de la lisse basse (2), fait un angle de 45 degrés avec la face extérieure (24) et un angle de 135 degrés avec la face intérieure (23).According to the illustrated embodiment, the first coupling face (25'), of a first angle portion (2a) intended to form half of an angle of the lower rail (2), makes an angle of 45 degrees with the outer face (24) and an angle of 135 degrees with the inner face (23).

Il est entendu que deux portions d'angle (2a) sont destinées à être agencées en opposition pour former un angle de la lisse basse (2).It is understood that two corner portions (2a) are intended to be arranged in opposition to form an angle of the lower rail (2).

Précisons que la seconde face d'accouplement (25) est perpendiculaire à la face intérieure (23) et à la face extérieure (24), de telle manière à ce que la seconde face d'accouplement (25) d'une portion d'angle (2a) puisse se connecter avec une face d'accouplement (25) d'une portion droite (2b).Let us specify that the second coupling face (25) is perpendicular to the interior face (23) and to the exterior face (24), such that the second coupling face (25) of a portion of angle (2a) can connect with a mating face (25) of a straight portion (2b).

Selon une caractéristique supplémentaire, une portion (2a, 2b) de lisse basse comprend un trou borgne (11) à chacune de ses extrémités, débouchant en direction d'une face d'accouplement (25) et en direction de la face supérieure (22).According to an additional characteristic, a portion (2a, 2b) of lower rail comprises a blind hole (11) at each of its ends, opening towards a coupling face (25) and towards the upper face (22 ).

Selon le mode de réalisation illustré, le trou borgne (11) a une forme complémentaire à une queue d'aronde.According to the illustrated embodiment, the blind hole (11) has a shape complementary to a dovetail.

Ainsi, le système de construction modulaire (1) comprend une pluralité de pièces d'accouplement (12) ayant chacune une forme complémentaire à deux trous borgnes (11) destinés à se positionner en opposition l'un de l'autre.Thus, the modular construction system (1) comprises a plurality of coupling parts (12) each having a complementary shape with two blind holes (11) intended to be positioned in opposition to each other.

Selon le mode de réalisation illustré notamment à la figure 3, une pièce d'accouplement (12) est constituée par deux queues d'aronde agencées en opposition.According to the embodiment illustrated in particular in Figure 3 , a coupling part (12) consists of two dovetails arranged in opposition.

Ainsi, une lisse basse (2) est assemblée par le positionnement successif de portions de lisse basse (2a, 2b), leurs faces d'accouplement (25, 25') complémentaires respectives étant positionnées en regard l'une de l'autre, accompagné de la connexion d'une pièce d'accouplement (12) dans les trous borgnes (11) des portions (2a, 2b) de lisse basse agencée en opposition.Thus, a lower rail (2) is assembled by the successive positioning of lower rail portions (2a, 2b), their respective complementary coupling faces (25, 25') being positioned facing each other, accompanied by the connection of a coupling part (12) in the blind holes (11) of the portions (2a, 2b) of lower rail arranged in opposition.

Selon une caractéristique complémentaire, la lisse basse comprend une première rainure (7) s'étendant dans la plus grande longueur de sa face supérieure.According to a complementary characteristic, the lower rail comprises a first groove (7) extending along the greatest length of its upper face.

Il est entendu qu'une pluralité de première rainure (7) contigüe est considérée comme une première rainure (7).It is understood that a plurality of contiguous first grooves (7) is considered as a first groove (7).

Selon la caractéristique précédente, la première rainure (7) s'étend de manière continue d'une portion droite (2b) à une portion d'angle (2a), de telle manière à ce qu'au niveau des angles de la lisse basse (2), la première rainure (7) s'étend de manière continue d'une portion d'angle (2a) à une autre, et forme un angle par exemple à 90 degré.According to the preceding characteristic, the first groove (7) extends continuously from a straight portion (2b) to a corner portion (2a), in such a way that at the corners of the lower rail (2), the first groove (7) extends continuously from one corner portion (2a) to another, and forms an angle, for example 90 degrees.

Ainsi, chacune des portions de lisse basse comprend une portion de première rainure (7) débouchante de part et d'autre en direction d'une face d'accouplement (25, 25'). Selon le mode de réalisation illustré, la lisse basse (2) comprend deux premières rainures (7) parallèles.Thus, each of the lower rail portions comprises a first groove portion (7) opening out on either side towards a coupling face (25, 25'). According to the illustrated embodiment, the lower rail (2) comprises two first parallel grooves (7).

Selon le mode de réalisation précédent, les deux premières rainures (7) de la lisse basse (2) s'étendent sensiblement aux extrémités intérieure et extérieure de la surface supérieure (22) le long des faces intérieure (23) et extérieure (24) respectivement.According to the previous embodiment, the first two grooves (7) of the lower rail (2) extend substantially to the inner and outer ends of the upper surface (22) along the inner (23) and outer (24) faces. respectively.

Selon un mode d'exécution, non représenté, l'une des deux premières rainures (7) de la lisse basse (2) s'étend sensiblement à l'extrémité extérieure de la surface supérieure (22) le long de la face extérieure (24), tandis que l'autre première rainure (7) s'étend sensiblement au centre de la surface supérieure (22) ou à une distance déterminée des bords de la face supérieure (22) selon les écartements des panneaux (5) d'une structure de poutre (3), telle qu'explicitée plus en détail dans la suite de la description.According to one embodiment, not shown, one of the first two grooves (7) of the lower rail (2) extends substantially at the outer end of the upper surface (22) along the outer face ( 24), while the other first groove (7) extends substantially in the center of the upper surface (22) or at a determined distance from the edges of the upper face (22) depending on the spacings of the panels (5) of a beam structure (3), as explained in more detail in the remainder of the description.

Selon un autre mode de réalisation, non représenté, la lisse basse (2) comprend trois premières rainures (7) parallèles, dont deux sont localisées le long de la face intérieure (23) et de la face extérieure (24) respectivement.According to another embodiment, not shown, the lower rail (2) comprises three first parallel grooves (7), two of which are located along the interior face (23) and the exterior face (24) respectively.

Selon un autre mode d'exécution, non représenté, la lisse basse (2) comprend uniquement une première rainure (7), de préférence localisée le long de la face extérieure (24).According to another embodiment, not shown, the lower rail (2) comprises only a first groove (7), preferably located along the exterior face (24).

Selon une caractéristique, la largeur (L1) d'une première rainure (7) est supérieure à la largeur (L2) d'une languette (4).According to one characteristic, the width (L1) of a first groove (7) is greater than the width (L2) of a tongue (4).

Précisons que selon la caractéristique précédente, le rapport (L1/L2) des largeurs de la première rainure (7) et de la languette (4) est compris entre 1,2 et 3.Let us specify that according to the preceding characteristic, the ratio (L1/L2) of the widths of the first groove (7) and the tongue (4) is between 1.2 and 3.

Plus précisément, le rapport (L1/L2) des largeurs de la première rainure (7) et de la languette (4) est compris entre 1,2 et 2,5, de préférence compris entre 1,3 et 2.More precisely, the ratio (L1/L2) of the widths of the first groove (7) and the tongue (4) is between 1.2 and 2.5, preferably between 1.3 and 2.

Selon un mode de réalisation, la largeur (L1) d'une première rainure (4) est comprise entre 9 et 20 millimètres, la largeur (L2) d'une languette (4) étant comprise entre 4 et 14 mm, tout en conservant le rapport (L1/L2) précité compris entre 1,2 et 3, de préférence compris entre 1,2 et 2,5, plus préférentiellement compris entre 1,3 et 2. Précisons que la largeur (L1) d'une première rainure (7) est constante tout le long de la lisse basse (2).According to one embodiment, the width (L1) of a first groove (4) is between 9 and 20 millimeters, the width (L2) of a tongue (4) being between 4 and 14 mm, while retaining the aforementioned ratio (L1/L2) between 1.2 and 3, preferably between 1.2 and 2.5, more preferably between 1.3 and 2. Let us specify that the width (L1) of a first groove (7) is constant all along the bottom rail (2).

La caractéristique précédente relative au rapport précité, permet d'obtenir un jeu entre les languettes (4) et la première rainure (4).The preceding characteristic relating to the aforementioned ratio makes it possible to obtain clearance between the tongues (4) and the first groove (4).

Précisons également que le rapport (L3/L2) de la largeur (L3) d'un panneau (5) et la largeur (L2) d'une languette (4) est avantageusement compris entre 1,8 et 4, de préférence compris entre 2 et 3.Let us also specify that the ratio (L3/L2) of the width (L3) of a panel (5) and the width (L2) of a tongue (4) is advantageously between 1.8 and 4, preferably between 2 and 3.

Les éléments structurels ont des tolérances de dimensionnements variable selon la précision des découpes des profilés de bois, l'assemblage notamment d'une série de structures de poutre (3) le long d'une lisse basse (2), engendre en bout, au niveau des angles une différence de longueur totale qui risque d'augmenter ou de diminuer selon la longueur du mur résultant, par rapport au prévision établie sur plan.The structural elements have variable sizing tolerances depending on the precision of the cuts of the wooden profiles, the assembly in particular of a series of beam structures (3) along a bottom rail (2), generates at the end, at level of the angles a difference in total length which may increase or decrease depending on the length of the resulting wall, compared to the forecast established on the plan.

Cette différence imprévisible de longueur d'un mur par rapport à la longueur de la lisse basse (2) correspondante, selon les prévisions sur plans, est ainsi absorbée par la différence des largeurs de la première rainure (7) et des languettes (4).This unpredictable difference in the length of a wall in relation to the length of the corresponding bottom rail (2), according to the forecasts on plans, is thus absorbed by the difference in the widths of the first groove (7) and the tongues (4) .

A cet effet, la différence de longueur attendue d'un alignement de structures de poutre (3), à savoir la différence de longueur d'un alignement de languettes (4) assemblées à des structures de poutre (3), par rapport à la lisse basse (2), est absorbée par la différence de largeur entre la première rainure (7) et la languette (4).For this purpose, the expected length difference of an alignment of beam structures (3), namely the length difference of an alignment of tongues (4) assembled to beam structures (3), relative to the lower smooth (2), is absorbed by the difference in width between the first groove (7) and the tongue (4).

Plus précisément, la différence précitée d'un mur rectiligne est absorbée par la différence de largeur de la partie de première rainure (7) et de la languette (4) correspondante, faisant en angle avec le mur rectiligne précité, à savoir la partie de la première rainure (7) de la partie de la lisse basse (2) perpendiculaire au mur précité, plus précisément perpendiculaire à la partie de lisse basse (2) soutenant les structures de poutre (3) constituant le mur précité.More precisely, the aforementioned difference of a rectilinear wall is absorbed by the difference in width of the part of first groove (7) and of the corresponding tongue (4), making an angle with the aforementioned rectilinear wall, namely the part of the first groove (7) of the part of the lower rail (2) perpendicular to the aforementioned wall, more precisely perpendicular to the part of the lower rail (2) supporting the beam structures (3) constituting the aforementioned wall.

Notons que la longueur d'un panneau (5) est comprise entre 300 à 3600 millimètres, de préférence, comprise entre 300 et 1500 millimètres.Note that the length of a panel (5) is between 300 and 3600 millimeters, preferably between 300 and 1500 millimeters.

Précisons que la largeur (L3) d'un panneau (5) est avantageusement comprise entre 18 et 27 millimètres.Let us specify that the width (L3) of a panel (5) is advantageously between 18 and 27 millimeters.

Rappelons que la tolérance sur la longueur d'un panneau (5) est de l'ordre d'un dixième de millimètres.Remember that the tolerance over the length of a panel (5) is of the order of a tenth of a millimeter.

Ainsi le rapport (L1/L2) des largeurs de la première rainure (7) et de la languette (4) compris entre 1,2 et 3, permet un positionnement optimisé des structures de poutre (3) sur la lisse basse (2) au vue de l'érection de la construction modulaire selon l'invention.Thus the ratio (L1/L2) of the widths of the first groove (7) and the tongue (4) between 1.2 and 3, allows optimized positioning of the beam structures (3) on the lower rail (2) with a view to the erection of the modular construction according to the invention.

Le dimensionnement particulier d'une première rainure (7), d'une languette (4) et d'un panneau (5), selon l'invention, permet un recouvrement d'une première rainure (7) par les panneaux, lors de l'assemblage d'un panneau (5) sur la lisse basse (2).The particular dimensioning of a first groove (7), a tongue (4) and a panel (5), according to the invention, allows a first groove (7) to be covered by the panels, when the assembly of a panel (5) on the lower rail (2).

Le tableau ci-dessous illustre des exemples de dimensionnement permettant le recouvrement d'une première rainure par un panneau, les valeurs indiquées sont exprimées en millimètres : [Table 1] Largeur panneau (L3) Largeur languette (L2) Largeur première rainure (L1) (L3-L2)/2 L1-L2 L1/L2 L3/L2 18 6 11 6 5 1.8 3 21 9 14 6 5 1.6 2.3 27 12 18 7.5 6 1.5 2.3 The table below illustrates examples of sizing allowing the covering of a first groove by a panel, the values indicated are expressed in millimeters: <u>[Table 1]</u> Panel width (L3) Tab width (L2) First groove width (L1) (L3-L2)/2 L1-L2 L1/L2 L3/L2 18 6 11 6 5 1.8 3 21 9 14 6 5 1.6 2.3 27 12 18 7.5 6 1.5 2.3

Ainsi, dans un cas extrême, selon les exemples précités, lorsque la languette est positionnée contre un des bords intérieurs d'une première rainure (7), les dimensionnements des différents éléments constitutifs de cet assemblage, permettent qu'un panneau (5) recouvre la première rainure (7), à savoir que la moitié de la différence de largeurs ((L3-L2)/2) d'un panneau (5) et de la languette (4), soit supérieure ou égale à la différence de largeurs (L1-L2) de la première rainure (7) et la languette (4). Il est entendu par un recouvrement d'une première rainure (7) par un panneau (5), qu'aucun espace visible ne soit présent entre la lisse basse (2) et un panneau (5). Ajoutons que selon une caractéristique avantageuse, une languette (4) comprend un joint s'étendant sur la longueur de la languette (4).Thus, in an extreme case, according to the aforementioned examples, when the tongue is positioned against one of the interior edges of a first groove (7), the dimensions of the different constituent elements of this assembly allow a panel (5) to cover the first groove (7), namely that half of the difference in widths ((L3-L2)/2) of a panel (5) and the tongue (4), is greater than or equal to the difference in widths (L1-L2) of the first groove (7) and the tongue (4). By covering a first groove (7) with a panel (5), it is understood that no visible space is present between the lower rail (2) and a panel (5). Let us add that according to an advantageous characteristic, a tongue (4) comprises a seal extending over the length of the tongue (4).
