Abstract
Description
La presente invention se situe dans le domaine des matériaux de construction. Elle concerne plus précisément des pièces allongées en bois utilisées dans la construction en général et présentant des caractéristiques mécaniques et esthétiques améliorées, particulièrement adaptées à la réalisation de structures porteuses. The present invention is in the field of building materials. It relates more precisely to elongated wooden parts used in construction in general and having improved mechanical and aesthetic characteristics, particularly suitable for the production of load-bearing structures.
Dans la plupart des cas, on est amené à considérer simultanément des critères de résistance mécanique, d'esthétique et de coût pour la réalisation d'une construction et le choix des matériaux. In most cases, it is necessary to simultaneously consider criteria of mechanical strength, aesthetics and cost for the realization of a construction and the choice of materials.
Le bois est souvent privilégie du fait de son aspect agréable et chaleureux mais du fait également de sa disponibilité surtout dans certaines régions. Wood is often preferred because of its pleasant and warm appearance but also because of its availability especially in certain regions.
Toutefois, son emploi massif a été freiné par les problèmes de séchage qu'il engendrait, à savoir des immobilisations très longues dans le cas du séchage naturel ou des difficultés de mise en oeuvre avec des procédés de séchage plus rapide (vapeur, pompe à chaleur, vide continu ou discontinu, etc.) et par les déformations qui en résultaient tels que vrillages et fendillements. However, its massive use was hampered by the drying problems that it generated, namely very long immobilizations in the case of natural drying or difficulties of implementation with faster drying processes (steam, heat pump , continuous or discontinuous vacuum, etc.) and by the resulting deformations such as twists and cracks.
On connaît maintenant des procédés qui permettent de maîtriser le séchage et les déformations du bois avant usinage et de le stabiliser, en particulier pour des pièces de fortes sections. On peut citer, par exemple, la technique dite "du bois percé" qui consiste à ôter longitudinalement le coeur de la pièce en bois. Processes are now known which make it possible to control the drying and deformations of the wood before machining and to stabilize it, in particular for parts with large sections. We can cite, for example, the technique called "drilled wood" which consists in longitudinally removing the heart of the wooden part.
On peut citer également l'utilisation des bois secs de faible section selon la technique du bois lamellé-collé qui consiste à préparer des pièces de forte section en bois reconstitué. We can also cite the use of dry wood of small cross-section using the glued laminated timber technique which consists in preparing large cross-section pieces of reconstituted wood.
Egalement, on cite des structures connues sous le nom général de "poutres en I", fabriquées à partir de composants bois associés à des matériaux dérivés du bois comme des panneaux de fibres ou de particules, contreplaqués, ou même des composants d'âmes métalliques connues sous la désignation commerciale "NAIL WEB". Also, there are cited structures known under the general name of "I-beams", made from wood components associated with wood-based materials such as plywood or particle board, or even metal core components. known under the trade designation "NAIL WEB".
Dans ces techniques, le bois massif en fortes sections est abandonné. In these techniques, solid wood in large sections is abandoned.
Le document FR-A-2 692 924 concerne une structure porteuse telle qu'un plancher comportant des poutres associées à une dalle béton, lesdites poutres présentant un évidement central et des moyens d'accrochages du béton, afin de former un ensemble indissociable.. Document FR-A-2 692 924 relates to a load-bearing structure such as a floor comprising beams associated with a concrete slab, said beams having a central recess and means for fastening the concrete, in order to form an inseparable assembly.
La présente invention privilégie l'esthétique et l'emploi du bois massif sec, présentant peu de fentes et déformations. The present invention favors the aesthetics and the use of dry solid wood, with few cracks and deformations.
L'objectif de la présente invention est donc de fournir des éléments de construction "prêt à l'emploi", présentant à la fois un caractère esthétique satisfaisant et des caractéristiques mécaniques améliorées. The objective of the present invention is therefore to provide building elements "ready to use", having both a satisfactory aesthetic character and improved mechanical characteristics.
La présente invention prend en compte des pièces massives allongées de section carrée ou rectangulaire proche du carré, pour lesquelles les tensions de séchage ont été libérées, dès le sciage, en créant mécaniquement une fente longitudinale à partir d'une de leurs faces, jusqu'aux environs du coeur. The present invention takes into account elongated massive pieces of square or rectangular section close to the square, for which the drying tensions have been released, from sawing, by mechanically creating a longitudinal slot from one of their faces, up to around the heart.
Après le séchage et l'usinage, les pièces obtenues présentent peu de déformations et de fissures et se stabilisent.After drying and machining, the parts obtained have little deformation and cracks and stabilize.
L'aspect esthétique est ainsi grandement amélioré.The aesthetic aspect is thus greatly improved.
Le sciage ne permet pas d'obtenir de telles pièces en grandes longueurs avec un rapport qualité / prix satisfaisant. Aussi, il est possible d'obtenir des pièces de grandes longueurs en jointant, bout à bout, des pièces allongées. Le procédé connu sous le nom d'aboutage est une manière de réaliser le jointage en longueur de deux pièces. Sawing does not make it possible to obtain such pieces in great lengths with a satisfactory quality / price ratio. Also, it is possible to obtain pieces of great length by joining, end to end, elongated pieces. The process known as butt jointing is a way of joining two pieces lengthwise.
Cependant, les caractéristiques mécaniques des pièces ainsi obtenues sont faibles particulièrement en flexion et commercialement insuffisantes en l'état. L'invention consiste à renforcer ces pièces ou membrures, en incorporant une âme en bois massif ou dérivés du bois tel que bois contrecollé, lamellé-collé, contreplaqué, ou panneau composite à base de bois, dans un évidement à bords parallèles préalablement aménagé dans la fente longitudinale de sciage, de plus grande dimension que celle-ci permettant le rattrapage des déformations dues au séchage. La membrure et l'âme sont rendues indissociables soit par collage et ou soit par liaison mécanique. However, the mechanical characteristics of the parts thus obtained are low, particularly in bending and commercially insufficient in the state. The invention consists in reinforcing these parts or members, by incorporating a core of solid wood or wood derivatives such as laminated wood, glulam, plywood, or wood-based composite panel, in a recess with parallel edges previously arranged in the longitudinal sawing slot, larger than this allowing the recovery of deformations due to drying. The frame and the core are made inseparable either by gluing or or by mechanical connection.
De meme, cet évidement de la membrure et au moins la partie encastrée de l'âme peuvent présenter des faces latérales présentant un angle compris entre 90 degrés et 105 degrés par rapport à la face inférieure respectivement de l'évidement et de l'âme, cet angle facilitant l'encastrement de l'âme dans la membrure et permettant d'améliorer la qualité de la liaison collée entre la membrure et l'âme. Likewise, this recess of the frame and at least the recessed part of the core may have lateral faces having an angle between 90 degrees and 105 degrees relative to the underside of the recess and the core respectively, this angle facilitating the embedding of the core in the frame and making it possible to improve the quality of the bonded bond between the frame and the core.
Selon l'invention, l'âme de l'élément de construction est encastrée dans l'évidement de la membrure, sur une partie de sa hauteur, de sorte à présenter la partie haute de ladite âme à l'extérieur de la membrure, dans le but d'augmenter fortement les caractéristiques mécaniques de l'élément de construction. According to the invention, the core of the construction element is embedded in the recess of the frame, over part of its height, so as to present the upper part of said core outside the frame, in the purpose of greatly increasing the mechanical characteristics of the building element.
La présente invention englobe également des éléments de construction (10) ainsi constitués. The present invention also encompasses building elements (10) thus formed.
De même, il est possible de renforcer, prealablement à leur emboîtement, les âmes rapportées, par l'apport d'au moins un élément de renfort longitudinal en matériaux métalliques ou de synthèse, par exemple des fibres de carbone, reçu dans au moins un rainurage longitudinal de forme correspondante à la section de l'élément de renfort et réalisés dans la partie haute et / ou basse, de façon débouchante ou non par rapport aux faces respectivement supérieure et inférieure de ladite âme. Les matériaux de renforts sont rendus indissociables de l'âme dans les rainurages de ladite âme, soit par collage et ou soit par liaisons mécaniques. Le ou les éléments de renfort peuvent être de sections arrondies comme par exemple des aciers ronds, des aciers béton ou des câbles, ou de sections diverses comme pour exemple des aciers plats ou des feuillards, de formes correspondantes aux rainurages réalisés. Ces renforts augmentent sensiblement la résistance mécanique de l'élément de construction. Similarly, it is possible to reinforce, prior to their nesting, the added cores, by the contribution of at least one longitudinal reinforcing element made of metallic or synthetic materials, for example carbon fibers, received in at least one longitudinal grooving of shape corresponding to the section of the reinforcing element and produced in the upper and / or lower part, with or without opening with respect to the respectively upper and lower faces of said core. The reinforcing materials are made inseparable from the core in the grooves of said core, either by bonding or or by mechanical connections. The reinforcing element or elements may be of rounded sections such as for example round steels, concrete steels or cables, or of various sections such as for example flat steels or strip, of shapes corresponding to the grooves produced. These reinforcements significantly increase the mechanical resistance of the building element.
De même, au moins un renfort métallique de l'âme peut être muni d'orifices longitudinaux ou verticaux pour améliorer la liaison collée entre la membrure, l'âme et ledit renfort. Placé dans un rainurage en partie basse de l'âme et un rainurage correspondant de la membrure, le renfort métallique améliore notablement les caractéristiques mécaniques de l'élément de construction et rend les aboutages envisageables de la membrure mécaniquement plus fiables. Likewise, at least one metal reinforcement of the core can be provided with longitudinal or vertical orifices to improve the bonded bond between the frame, the core and said reinforcement. Placed in a groove in the lower part of the core and a corresponding groove in the frame, the metal reinforcement significantly improves the mechanical characteristics of the construction element and makes the possible connections of the frame mechanically more reliable.
De même, il est possible d'exercer une traction sur au moins un des éléments de renfort, constitués de câbles ou tirants de précontrainte, mis en tension aux extrémités des éléments de construction. Cette précontrainte appliquée dans la partie basse de l'élément de construction permet d'améliorer fortement les caractéristiques mécaniques en flexion dudit élément de construction. Similarly, it is possible to exert traction on at least one of the reinforcing elements, consisting of cables or prestressing tie rods, tensioned at the ends of the construction elements. This prestress applied in the lower part of the construction element makes it possible to greatly improve the mechanical flexural characteristics of said construction element.
Les éléments de construction selon la présente invention sont destinés à des applications en structures très diverses, horizontales telles que des planchers techniques porteurs, verticales telles que des colombages porteurs ou autres, ou telles que des charpentes ou telles que des structures tridimensionnelles. Dans la plupart des applications en structures, des éléments d'assemblages mécaniques sont mis en oeuvre pour permettre des liaisons entre plusieurs éléments de construction (10). Ils peuvent consister en renforts d'assemblages comme des goussets métalliques ou en contreplaqué ou panneaux composites, ou comme des connecteurs métalliques dentés. The building elements according to the present invention are intended for applications in very diverse structures, horizontal such as load-bearing technical floors, vertical such as load-bearing studs or the like, or such as frameworks or such as three-dimensional structures. In most structural applications, mechanical assembly elements are used to allow connections between several construction elements (10). They can consist of reinforcements of assemblies like metallic gussets or plywood or composite panels, or like toothed metallic connectors.
Dans certaines applications en structures porteuses ou non, les éléments de construction sont reliés entre eux par des panneautages tels que bardages divers, contreplaqués, panneaux dérivés du bois ou du ciment ou d'autres matériaux. In certain applications in load-bearing or non-load-bearing structures, the construction elements are interconnected by paneling such as various cladding, plywood, panels derived from wood or cement or other materials.
A cette fin, les panneautages sont étendus entre les éléments de construction et fixés par collages ou moyens de liaison mécanique sur l'une quelconque des faces longitudinales desdits éléments de construction. Les faces longitudinales de fixations et d'appuis sont déterminées en fonction des caractéristiques mécaniques envisagées pour les structures et de l'aspect esthétique recherché du bois massif. Les panneautages associés aux éléments de construction selon la présente invention participent fortement aux qualités mécaniques globales de la structure notamment en matière de contreventement.To this end, the panels are extended between the construction elements and fixed by gluing or mechanical connection means on any one of the longitudinal faces of said construction elements. The longitudinal faces of fixings and supports are determined according to the mechanical characteristics envisaged for the structures and the desired aesthetic appearance of solid wood. The paneling associated with the construction elements according to the present invention strongly contributes to the overall mechanical qualities of the structure, particularly in terms of bracing.
De même, l'âme de l'élément de construction peut etre un profilé creux réalisé en tôle mince longitudinale pliée, rendue indissociable de la membrure au fond et sur les côtés de l'évidement soit par collage et ou soit par liaison mécanique. Likewise, the core of the construction element can be a hollow profile made of folded longitudinal thin sheet metal, made inseparable from the frame at the bottom and on the sides of the recess either by gluing or or by mechanical connection.
De même, cette âme en profilé creux réalisé en tôle mince longitudinale pliée peut être munie d'orifices de formes diverses sur la partie haute de l'âme, extérieure à la membrure. Likewise, this hollow profile core made of folded longitudinal thin sheet can be provided with orifices of various shapes on the upper part of the core, external to the frame.
De tels éléments de construction comportant une âme en profilé creux realisé en tôle mince longitudinale pliée et ou non munie d'orifices, sont destinés à des applications en structures, comme des planchers techniques, des charpentes et des structures tridimensionnelles. Dans ces applications, les assemblages entre éléments de construction seront notablement facilités par l'emploi d'organes d'assemblages mécaniques encastrés et fixés mécaniquement dans les extrémités creuses des âmes en profilé creux. De même, les orifices crées dans la partie de l'âme en profilé creux extérieure de la membrure peuvent être judicieusement prévus en formes et dimensions, pour permettre l'emploi d'organes d'assemblages mécaniques entre plusieurs éléments de construction. Such building elements comprising a hollow profile core made of folded longitudinal thin sheet metal or not provided with orifices, are intended for applications in structures, such as raised floors, frameworks and three-dimensional structures. In these applications, the assemblies between construction elements will be notably facilitated by the use of mechanical assembly members embedded and mechanically fixed in the hollow ends of the hollow profile cores. Likewise, the orifices created in the part of the core in an outer hollow profile of the frame can be judiciously provided in shapes and dimensions, to allow the use of mechanical assembling members between several construction elements.
L'invention sera mieux comprise à la lecture de la description donnée ci-après à titre d'exemple illustratif et non limitatif ainsi que des dessins dans lesquels:
