Description

POUTRE DE BOIS DE TYPE RECONSTITUE.RECONSTRUCTED TYPE WOOD BEAM.
La présente invention concerne une poutre de bois de type reconstitué .The present invention relates to a reconstructed type wooden beam.
Il n'est pas rare que les particuliers ou les professionnels du bâtiment utilisent des poutres de bois de type reconstitué, d'un prix inférieur à celui de poutres en bois massif, pour la décoration d'une pièce dans un style rustique ou campagnard ou la réalisation de certaines structures comme par exemple des éléments de charpente .It is not uncommon for individuals or building professionals to use reconstituted wood beams, at a lower price than solid wood beams, for decorating a room in a rustic or country style or the realization of certain structures such as for example structural elements.
Ce type de poutre dite reconstituée est traditionnellement un assemblage d'éléments de bois, lesdits éléments étant assemblés de manière à obtenir la forme et l'aspect général d'une pièce ou d'une poutre en bois massif.This type of so-called reconstituted beam is traditionally an assembly of wood elements, said elements being assembled so as to obtain the shape and the general appearance of a part or of a solid wood beam.
Un des inconvénients des poutres de bois de type reconstitué de l'art antérieur est que, étant construites avec une multitude d'éléments qui ne sont pas stables dimensionnellement, ces poutres ont une structure qui a tendance à se désagréger rapidement au cours du temps .One of the drawbacks of wood beams of the reconstituted type of the prior art is that, being constructed with a multitude of elements which are not dimensionally stable, these beams have a structure which tends to disintegrate rapidly over time.
Un autre inconvénient des poutres de type reconstitué de l'art antérieur est que pour une poutre reconstituée donnée, les éléments qui la composent doivent être issus d'une seule et même essence de bois .Another disadvantage of beams of the reconstituted type of the prior art is that for a given reconstituted beam, the elements which compose it must come from one and the same species of wood.
En effet, les différentes essences de bois ne réagissent pas de la même manière aux éléments extérieurs (hygrométrie, température ambiante...). Un assemblage d'éléments de bois de différentes essences ne peut être envisagé compte-tenu des différences de variations dimensionnelles entre des éléments de bois de différentes essences . La poutre de bois de type reconstitué selon l'invention permet de remédier aux inconvénients de l' art antérieur .Indeed, the different species of wood do not react in the same way to external elements (humidity, ambient temperature ...). An assembly of elements of wood of different species cannot be envisaged taking into account the differences in dimensional variations between elements of wood of different species. The wooden beam of the reconstituted type according to the invention overcomes the drawbacks of the prior art.
Conformément à l'invention, ce résultat est obtenu par une poutre de type reconstitué caractérisée en ce qu'elle comporte essentiellement une structure centrale ou âme et un habillage extérieur solidarisé à ladite structure centrale ou âme, ladite structure centrale ou âme étant réalisée à partir de pièces de bois d'au moins une essence, et en ce qu'au moins une partie des pièces de bois réalisant respectivement la structure centrale ou âme et l'habillage extérieur a été préalablement chauffée à haute température.According to the invention, this result is obtained by a beam of the reconstituted type, characterized in that it essentially comprises a central structure or core and an external covering secured to said central structure or core, said central structure or core being produced from pieces of wood of at least one species, and in that at least a part of the pieces of wood respectively producing the central structure or core and the external covering have been previously heated to high temperature.
Dans la description, le terme « poutre » n'est pas limitatif et peut désigner également des chevrons, solives, etc....In the description, the term "beam" is not limiting and can also designate rafters, joists, etc.
De manière préférentielle, l'ensemble des pièces de bois réalisant respectivement la structure centrale ou âme et l'habillage extérieur ont été préalablement chauffées à haute température.Preferably, all of the pieces of wood respectively producing the central structure or core and the exterior covering were previously heated to high temperature.
Avantageusement, la structure centrale ou âme est réalisée à partir de pièces de bois de plusieurs essences .Advantageously, the central structure or core is made from pieces of wood of several species.
Suivant une autre caractéristique avantageuse de mise en oeuvre, la ou les essences de bois utilisées pour les pièces de bois réalisant la structure centrale ou âme sont différentes de l'essence de bois utilisée pour les pièces de bois réalisant l'habillage extérieur.According to another advantageous characteristic of implementation, the species of wood used for the pieces of wood making the central structure or core are different from the essence of wood used for the pieces of wood making the exterior cladding.
De manière préférentielle, les essences de bois utilisées pour les pièces de bois réalisant la structure centrale ou âme sont des essences communes . On entend par « essences communes » des essences de bois qui sont généralement peu onéreuses à l'achat (résineux, peupliers, eucalyptus...). En outre , l' essence de bois utilisée pour les pièces de bois réalisant l'habillage extérieur est une essence noble.Preferably, the species of wood used for the pieces of wood forming the central structure or core are common species. “Common species” means wood species which are generally inexpensive to purchase (coniferous, poplar, eucalyptus, etc.). In addition, the essence of wood used for the pieces of wood making the exterior cladding is a noble essence.
On emploie le terme « essence noble » pour une essence de bois plus chère par opposition aux « essences communes » utilisées dans la structure centrale ou âme de la poutre, donc non visibles de l' extérieur.The term "noble species" is used for a more expensive wood species as opposed to the "common species" used in the central structure or core of the beam, therefore not visible from the outside.
Par exemple, le bois d'essence noble réalisant l'habillage extérieur est choisi dans le groupe (chêne, noyer, frêne, orme, érable) et/ou dans le groupe (acajou, teck, ébène, sépoi sapelli, palissandre) .For example, the wood of noble essence making the exterior cladding is chosen from the group (oak, walnut, ash, elm, maple) and / or from the group (mahogany, teak, ebony, sapelo sep, rosewood).
Avantageusement, les éléments de bois d'essence noble, réalisant l'habillage extérieur de la poutre, sont également préalablement chauffés à haute température.Advantageously, the elements of noble essence wood, making the external covering of the beam, are also previously heated to high temperature.
On comprendra mieux l'invention à l'aide de la description ci- après donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :The invention will be better understood with the aid of the description below given by way of nonlimiting example, with reference to the appended drawings in which:
- la figure 1 est une vue en perspective d'une poutre de bois de type reconstitué selon l'invention,FIG. 1 is a perspective view of a wooden beam of the reconstituted type according to the invention,
- la figure 2 est une vue déchirée en perspective de la poutre de bois de la igure 1.- Figure 2 is a torn perspective view of the wooden beam of Figure 1.
Comme illustré à la figure 1 , une poutre de bois de type reconstitué comporte une structure centrale ou âme (1) .As illustrated in Figure 1, a reconstructed type wooden beam has a central structure or core (1).
Une poutre de type reocnstitué comporte également un habillage extérieur (2) garnissant la structure centrale ou âme (1) .A reconstituted type beam also includes an external covering (2) lining the central structure or core (1).
Comme illustré à la figure 2, la structure centrale ou âme (1) est constituée d'un assemblage de pièces de bois (4) d'une ou plusieurs essences différentes préalablement chauffées à haute température garantissant auxdites pièces de bois une stabilité dimensionnelle, lesdites essences étant préférentiellement différentes de celle utilisée pour 1 ' habillage extérieur .As illustrated in Figure 2, the central structure or core (1) consists of an assembly of pieces of wood (4) of one or several different species previously heated to high temperature guaranteeing said pieces of wood dimensional stability, said species being preferably different from that used for one exterior covering.
Certaines pièces de bois (4) réalisant la structure centrale ou âme sont assemblées suivant la technique dite de lamellation ou lamellé-collé .Certain pieces of wood (4) forming the central structure or core are assembled using the technique known as laminating or glulam.
Cette technique consiste à réaliser un assemblage de pièces de bois , par exemple des planches , des lames ou des placages en superposant lesdites pièces, de manière préférentielle à fil parallèle, et en les solidarisant par collage.This technique consists in assembling pieces of wood, for example planks, boards or veneers by superimposing said pieces, preferably with parallel wire, and joining them by gluing.
Suivant une autre caractéristique de l'invention, la structure centrale ou âme (1) comporte au moins un insert métallique (non représenté) s'étendant le long de l'axe longitudinal de la poutre .According to another characteristic of the invention, the central structure or core (1) comprises at least one metal insert (not shown) extending along the longitudinal axis of the beam.
On obtient ainsi une poutre de type reconstitué avec une rigidité améliorée.A beam of the reconstituted type is thus obtained with improved rigidity.
En outre, l'habillage extérieur (2) est un assemblage de pièces de bois (3) d'essence noble.In addition, the outer covering (2) is an assembly of pieces of wood (3) of noble essence.
Suivant une autre caractéristique, les pièces de bois réalisant l'habillage extérieur sont assemblées suivant la technique dite de lamellation (lamellé-collé) .According to another characteristic, the pieces of wood making the exterior cladding are assembled according to the so-called laminating technique (glulam).
Suivant une autre caractéristique, l'habillage extérieur (2) est solidarisé à la structure centrale ou âme (1) de la poutre par collage .According to another characteristic, the outer covering (2) is secured to the central structure or core (1) of the beam by gluing.
Suivant un mode particulier de réalisation, l'habillage extérieur ne peut se limiter à deux faces de la poutre, par exemple si la poutre est fixée au niveau de la jonction d'un pan de mur et d'un plafond.According to a particular embodiment, the external covering cannot be limited to two faces of the beam, by example if the beam is fixed at the junction of a wall section and a ceiling.
Les avantages et les intérêts de la présente invention sont nombreux et notamment :The advantages and advantages of the present invention are numerous and in particular:
- valorisation de bois de faible prix et de faible intérêt, stabilisation dimensionnelle des poutres de type reconstitué, - utilisation sur une même structure de bois de différentes origines .- recovery of low-cost and low-interest wood, dimensional stabilization of reconstituted type beams, - use on the same wood structure of different origins.
En outre, les progrès des techniques du bâtiment font que les poutres sont placées dans des supports cloisonnés interdisant les déformations ou « travail du bois ».In addition, advances in building techniques mean that the beams are placed in partitioned supports preventing deformation or "woodworking".
Ainsi, des poutres de type reconstitué suivant l'invention, par leur stabilité dimensionnelle, peuvent avantageusement remplacer des poutres en bois massif dans les constructions modernes .Thus, beams of the reconstituted type according to the invention, by their dimensional stability, can advantageously replace solid wood beams in modern constructions.
La présente invention trouve son application dans la décoration et les structures de construction dans le bâtiment. The present invention finds its application in decoration and construction structures in the building.
