Abstract

Method for fabricating angular elements with glued lamellated wood from pre-assembled wooden blades (version I) or blades prefitted with mechanical assembly devices (version II) and its alternative (version III). The angular element is fabricated by piling the blades (a1, a2, a3, a4, b1, b2, b3, b4) which are successively assembled on fabrication toolings in order to form the two branches (A and B) of the angular element. The version II alternative provides for the dissociation of the two branches of the angular element after its fabrication. The version III comprises the fabrication of straight elements (A and B) whose geometry and pre-equipment are complementary. The mounting of the angular elements of the version II and version III are obtained through mechanical assembly devices. The method is particularly adapted to the construction of dwellings, houses etc.

Le procédé comporte trois versions et la variante version II. The process has three versions and the version II variant.
La version I consiste à fabriquer des éléments angulaires à partir de sous-ensembles composés de lames assemblées aux angles de la structure: chaque lame d'une même branche de l'élément angulaire est assemblée à la lame correspondante de la seconde branche.Ces sous-ensembles sont ensuite regroupés pour la fabrication du lamelle collé. Version I consists of manufacturing angular elements from sub-assemblies composed of blades assembled at the corners of the structure: each blade of the same branch of the angular element is assembled with the corresponding blade of the second branch. -sets are then grouped together for the manufacture of the glued strip.
La version II consiste à fabriquer des éléments angulaires à partir de lames prééquipées de dispositifs d'assemblages mécaniques suivant "Le procédé d'assemblage,notamment du bois utilisant des inserts d'ancrage" :il s'agit d'un assemblage vissé dont l'ancrage de l'élément fileté est renforcé par l'implantation d'un insert cylindrique taraudé par le vissage à force de l'élément fileté d'assemblage;les lames prééquipées sont empilées et assemblées alternativement sur l'outillage de fabrication pour former les deux branches de l'élément angulaire après encollage. Version II consists of manufacturing angular elements from blades pre-equipped with mechanical assembly devices according to "The assembly process, in particular of wood using anchoring inserts": it is a screw assembly of which anchoring of the threaded element is reinforced by the implantation of a threaded cylindrical insert by force screwing of the threaded assembly element; the pre-equipped blades are stacked and assembled alternately on the manufacturing tool to form the two branches of the angular element after gluing.
La variante à la version II permet de dissocier les deux branches d'un élément angulaire après sa fabrication : elle consiste à placer en- fabrication des épargnes de colle sur les extrémitées des lames qui forment les plans de contacts The variant in version II makes it possible to dissociate the two branches of an angular element after its manufacture: it consists in placing in-manufacture glue savings on the ends of the blades which form the contact planes
de chaque branche et de pratiquer en fonction de leurs positions respectives des lumières d'accès aux éléments filetés par le perçage des lames de chaque branche dans l'axe des éléments filetés suivant le sens du dévissage.  of each branch and practice according to their respective positions of the access lights to the threaded elements by drilling the blades of each branch in the axis of the threaded elements in the direction of unscrewing.
Lors du montage final les deux branches sont maintenues dans leurs positions définitives, les éléments filetés sont vissés sur leurs inserts respectifs , après encollage des plans de contacts. La version III est un systéme α'asc emblage suivant lequej les

sont décomposées en éléments droits ou en arcs;les éléments formant les deux branches d'un angle sont fabriqués séparément sur des outillages équipés de gabarits simulant les interfaces avec les éléments juxtaposés,à partir de lames préé- quipées de dispositifs d'assemblages mécaniques identiques à ceux de la version II. During the final assembly, the two branches are maintained in their final positions, the threaded elements are screwed onto their respective inserts, after gluing of the contact planes. Version III is an α'asc emblem system according to which the

are broken down into straight elements or arcs; the elements forming the two branches of an angle are manufactured separately on tools fitted with templates simulating the interfaces with the juxtaposed elements, from blades pre-equipped with identical mechanical assembly devices to those of version II.
La procédure de montage est identique à celle de la variante de la version II.  The assembly procedure is identical to that of the version II variant.
Les lumières d'accès aux éléments filetés sont obturées après le montage définitif par des chevilles en bois ajustées etplacées à force sur la tête des éléments filetés,avec adjonction de colle ou produit adéquat afin de réduire tout interstice. The access lights to the threaded elements are closed after final assembly by adjusted wooden dowels and placed by force on the head of the threaded elements, with the addition of glue or suitable product to reduce any gaps.
Suivant l'une ou l'autre des versions et variante, les dispositifs d'assemblages peuvent être placés pour travailler en arrachement, en cisaillement ou la combinaison des deux. According to one or other of the versions and variant, the assembling devices can be placed to work in tearing, in shearing or the combination of the two.
Suivant l'une quelconque des versions et variante, des accessoires de répartition sont placés sous la tête des éléments filetés : rondelles élastiques, plaques métalliques spécifiques, avec adjonction de résine ou similaire. Le procédé d'assemblage mécanique utilisant des inserts d'ancrage permet d'assembler des lames à l'équerre ainsi qu'à des angles différents suivant la position du dispositif et en particulier de l'insert. La présente description est complétée par des dessins : les figures 1 à 3 montrent l'empilage des lames en fabrication du lamelle collé ; les figures 4a, 4b et 4c représentent un assemblage dissocié de la variante version II. According to any one of the versions and variant, distribution accessories are placed under the head of the threaded elements: elastic washers, specific metal plates, with the addition of resin or the like. The mechanical assembly process using anchoring inserts makes it possible to assemble blades at right angles as well as at different angles depending on the position of the device and in particular of the insert.
