Abstract

The supporting structure consists of a series of inverted trough-section metal profiles (2, 3) of different heights but constant cross-section mounted on a girder infrastructure (1). The profiles have stiffening ribs (22, 32; 24, 34) in the form of U- or V-section grooves along their tops (21) and sides (23), and their bases (25) also have stiffened edges (26). The ends of the profiles have holes for fixing bolts.

Description

La présente invention concerne le domaine du bâtiment, en particulier des bâtiments industriels ou d'habitation à structure métallique et a pour objet une structure de support en éléments profilés.The present invention relates to the building field, in particularly industrial or residential buildings with a metallic structure and relates to a support structure made of profiled elements.

Actuellement, les structures de support de bâtiments à structure métallique, telles que les pannes pour toitures, les lisses pour bardages, les solives pour planchers, ainsi que tous les autres éléments structurels porteurs, sont généralement réalisées sous forme de profils de formes géométriques diverses, réalisés par profilage à froid ou par laminage à chaud. A cet effet, on distingue essentiellement deux types de profils, suivant leur comportement mécanique, à savoir les profils fermés en forme de tubes et les profils ouverts du type profils en I, en C, en Z, etc...Currently, support structures for structured buildings metallic, such as purlins for roofs, beams for cladding, joists for floors, as well as all other structural elements carriers, are generally made in the form of profile profiles various geometries, produced by cold profiling or by rolling hot. For this purpose, there are essentially two types of profiles, according to their mechanical behavior, namely closed shaped profiles of tubes and open profiles of the I, C, Z profiles type, etc.

Les profils fermés présentent une grande rigidité en flexion dans les deux sens, ainsi qu'en torsion et ne sont, de ce fait, pas exposés à un risque d'instabilité par déversement. Par contre, les profils ouverts présentent habituellement une importante rigidité en flexion dans un sens, alors que dans l'autre sens cette rigidité est faible. De même, la rigidité en torsion de tels profils est également faible, occasionnant ainsi leur instabilité par déversement.Closed profiles have high bending stiffness in both directions, as well as in torsion and are therefore not exposed to risk of instability due to spillage. However, open profiles usually have significant bending stiffness in one direction, whereas in the other direction this rigidity is low. Similarly, the rigidity in torsion of such profiles is also low, thus causing their instability by spillage.

Pour l'obtention de caractéristiques mécaniques améliorées, en utilisant les gammes de produits existant actuellement, il a été proposé d'assembler ces produits, généralement de manière inversée. Ainsi, sont réalisés des profils symétriques par assemblage de profils de base identiques dos à dos, ce qui a pour effet d'améliorer leur comportement en torsion et/ou en flexion.To obtain improved mechanical characteristics, in using the existing product ranges, it has been proposed to assemble these products, generally in a reverse manner. So are produced symmetrical profiles by assembling basic profiles identical back to back, which improves their behavior by torsion and / or flexion.

Cependant, de tels modes de réalisation entraínent une augmentation substantielle du poids des profils obtenus, de sorte qu'il subsiste un effet pénalisant par rapport à l'augmentation des performances obtenues.However, such embodiments result in a substantial increase in the weight of the profiles obtained, so that it there remains a penalizing effect compared to the increase in performance obtained.

En outre, ces profils connus ne sont généralement pas emboítables en respectant une hauteur prédéterminée et doivent être reliés entre eux par un éclissage, la hauteur des profils d'un type donné étant pratiquement toujours identique. Un tel éclissage est réalisé par l'intermédiaire d'une pièce de section différente rapportée entre les profils, généralement sur leur flanc vertical, et présentant souvent des caractéristiques mécaniques inférieures à celles des profils qu'elle relie, l'ensemble des efforts appliqués passant essentiellement dans les moyens d'assemblage de l'éclisse et des profils, à savoir dans des vis ou des boulons. Il en résulte qu'une structure ainsi réalisée peut présenter des points d'affaiblissement préjudiciable à leur bonne tenue dans le temps sous toutes les conditions atmosphériques.In addition, these known profiles are generally not nestable respecting a predetermined height and must be connected between them by a joint, the height of the profiles of a given type being almost always the same. Such splicing is carried out by through a part of different section attached between the profiles, generally on their vertical side, and often presenting mechanical characteristics inferior to those of the profiles it connects, all of the applied efforts essentially passing through the means for joining the splice bar and the profiles, namely in screws or bolts. It follows that a structure thus produced may have points weakening detrimental to their good performance over time under all atmospheric conditions.

On connaít également, par US-A-4 106 253, des liteaux métalliques sous forme de profilés, qui ne peuvent pas s'emboíter, la continuité entre ces liteaux étant assurée par l'intermédiaire d'éclisses intérieures.We also know, from US-A-4 106 253, battens metal in the form of profiles, which cannot fit together, the continuity between these battens being ensured by means of splints interior.

Les profilés selon ce document sont très spécifiques et servent uniquement à la fixation de tuiles en toiture. Ils ne sont pas applicables à d'autres types de couverture, ni aux contraintes liés à des bâtiments industriels, du fait qu'ils ne peuvent former une structure de support pouvant être porteuse.The profiles according to this document are very specific and serve only for fixing roof tiles. They are not applicable to other types of roofing, or constraints linked to buildings industrial, because they cannot form a support structure that can be a carrier.

Par ailleurs, GB-A-269 203 décrit un dispositif de fixation de plaques de verre qui assure une fonction d'étanchéité et qui est essentiellement constitué par un assemblage de profilés de nature différente, qui ne sont en aucun cas emboítables.Furthermore, GB-A-269 203 describes a device for fixing glass plates which provides a sealing function and which is essentially constituted by an assembly of profiles of a different nature, which are in no case nestable.

La présente invention a pour but de pallier ces inconvénients en proposant une structure de support en éléments profilés permettant l'obtention d'une continuité de surface entre des profils aboutés, sans risque de déformation sous charge et sans adjonction de pièce supplémentaire.The object of the present invention is to overcome these drawbacks by proposing a support structure in profiled elements allowing obtaining surface continuity between butted profiles, without risk deformation under load and without the addition of additional parts.

A cet effet, la structure de support en éléments profilés, montée sur des poutres d'infrastructure, est caractérisée en ce qu'elle est essentiellement constituée par des éléments profilés présentant des hauteurs différentes et une section transversale en forme de chapeau, constante.For this purpose, the support structure in profiled elements, mounted on infrastructure beams, is characterized in that it is essentially constituted by profiled elements having heights different and a constant hat-shaped cross section.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en perspective d'une structure de support conforme à l'invention ;
  • la figure 2 est une vue analogue à celle de la figure 1 d'une variante de réalisation de l'invention ;
  • les figures 3 et 4 représentent, en perspective, deux modes de réalisation de liaison entre des éléments profilés ;
  • la figure 5 est une vue en perspective représentant un montage de caisson, et
  • la figure 6 est une vue analogue à celle de la figure 4 représentant une variante de réalisation de l'extrémité des éléments profilés.
    • The invention will be better understood from the following description, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a perspective view of a support structure according to the invention;
  • Figure 2 is a view similar to that of Figure 1 of an alternative embodiment of the invention;
  • Figures 3 and 4 show, in perspective, two embodiments of connection between profiled elements;
  • FIG. 5 is a perspective view showing a box assembly, and
  • Figure 6 is a view similar to that of Figure 4 showing an alternative embodiment of the end of the profiled elements.

    • Conformément à l'invention et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 des dessins annexés, la structure de support en éléments profilés, qui est montée sur des poutres d'infrastructure 1, est essentiellement constituée par des éléments profilés 2, 3 présentant des hauteurs différentes et une section transversale en forme de chapeau, constante.According to the invention and as shown more particularly, by way of example, Figures 1 and 2 of the accompanying drawings, the support structure in profiled elements, which is mounted on beams of infrastructure 1, is essentially constituted by profiled elements 2, 3 with different heights and a cross section in the form of hat, constant.

    Comme le montrent les figures des dessins annexés, les éléments profilés 2 et 3 présentent une section transversale identique en forme de chapeau, section dont la plage 21, 31 est pourvue d'au moins un raidisseur 22, 32 et dont les âmes latérales 23, 33 sont également pourvues chacune d'au moins un raidisseur 24, 34, les semelles 25, 35 étant pourvues chacune d'un moyen extérieur de raidissage 26, 36. Ainsi, il est possible de réaliser une continuité parfaite avec des profils 2 et 3 de hauteur identique ou variable, par chevauchement ou emboítement total ou partiel, les seuls décalages en hauteur étant dus à l'épaisseur de la matière constitutive desdits profils 2 et 3.As shown in the figures of the accompanying drawings, the profiled elements 2 and 3 have an identical cross section in hat shape, cross-section the area 21, 31 of which is provided with at least one stiffener 22, 32 and whose lateral cores 23, 33 are also provided each of at least one stiffener 24, 34, the flanges 25, 35 being provided each of an external stiffening means 26, 36. Thus, it is possible to achieve perfect continuity with profiles 2 and 3 of identical height or variable, by total or partial overlap or nesting, the only ones height offsets being due to the thickness of the constituent material said profiles 2 and 3.

    De préférence, la plage 21, 31 est pourvue de deux raidisseurs 22, 32 en forme de nervures longitudinales formant des sillons en U ou en V, ces nervures longitudinales étant avantageusement disposées près des plis de liaison aux âmes latérales 23, 33. Ainsi, il subsiste entre les raidisseurs 22, 32 un espace libre pouvant permettre, notamment, la fixation d'éléments d'assemblage, tels que des boulons, des vis auto-taraudeuses, des clous. Les nervures longitudinales en forme de sillons en U ou en V constituant les raidisseurs 22, 32 permettent d'améliorer notablement la résistance au voilement local de la plage 21, 31. Chaque raidisseur 24, 34 prévu dans les âmes latérales 23, 33 se présente sous forme d'un épaulement ménagé dans lesdites âmes 23, 33. Ainsi, les âmes latérales 23, 33 se présentent sous forme de raidisseurs du type en Z.Preferably, the track 21, 31 is provided with two stiffeners 22, 32 in the form of longitudinal ribs forming U-shaped or V, these longitudinal ribs being advantageously arranged near the folds connecting to the lateral cores 23, 33. Thus, it remains between the stiffeners 22, 32 a free space which can allow, in particular, the fixing connecting elements, such as bolts, self-tapping screws, nails. Longitudinal ribs in the shape of U or V grooves constituting the stiffeners 22, 32 make it possible to significantly improve the resistance to local warping of the range 21, 31. Each stiffener 24, 34 provided in the lateral cores 23, 33 is in the form of a shoulder provided in said cores 23, 33. Thus, the lateral cores 23, 33 are in the form of Z-type stiffeners.

    Selon une caractéristique de l'invention, plusieurs raidisseurs 24, 34 peuvent être prévus sur chaque âme latérale 23, 33. Un tel mode de réalisation permet l'obtention d'une résistance accrue contre le voilement desdites âmes latérales. According to a characteristic of the invention, several stiffeners 24, 34 can be provided on each lateral core 23, 33. Such a mode of realization allows obtaining an increased resistance against buckling said lateral souls.

    Les raidisseurs 24, 34 des âmes latérales 23, 33 présentent, pour tous les profils 2, 3, une distance constante par rapport à la plage 21, 31 correspondante desdits profils 2, 3, les raidisseurs 22, 32 desdites plages 21, 31 étant disposés à intervalles constants et identiques sur celles-ci. Ainsi, un profil 3 de relativement faible hauteur (figures 1 et 4), peut s'appuyer sur un profil 2 de hauteur plus importante, les raidisseurs 34 des âmes latérales 33 s'appuyant alors simplement sur les raidisseurs 24 correspondants du profil 2 de plus grande hauteur.The stiffeners 24, 34 of the lateral webs 23, 33 have, for all profiles 2, 3, a constant distance from range 21, 31 corresponding to said profiles 2, 3, the stiffeners 22, 32 of said areas 21, 31 being arranged at constant and identical intervals thereon. Thus, a profile 3 of relatively low height (Figures 1 and 4), can lean on a profile 2 of greater height, the stiffeners 34 of lateral webs 33 then simply resting on the stiffeners 24 corresponding to profile 2 of greater height.

    Enfin, les moyens extérieurs de raidissage 26 36 prévus sur les semelles 25, 35, prolongeant les extrémités des âmes latérales 23, 33 du côté opposé à la plage 21, 31, se présentent sous forme de bords relevés. Ces bords relevés formant les moyens extérieurs de raidissage 26, 36 ont pour effet d'accentuer la résistance à la flexion et au voilement des semelles 25, 35.Finally, the external stiffening means 26 36 provided on the soles 25, 35, extending the ends of the lateral webs 23, 33 of the side opposite to the area 21, 31, are in the form of raised edges. These raised edges forming the external stiffening means 26, 36 have to increase resistance to flexing and buckling of the soles 25, 35.

    L'assemblage de deux profils 2 et/ou 3de hauteurs identiques ou différentes peut ensuite être réalisé, de manière connue, comme le montrent les figures 1 et 3, par boulonnage ou vissage au niveau des plages 21, 31. Le nombre de vis ou de boulons est fonction des sollicitations auxquelles sont soumis les assemblages.The assembly of two profiles 2 and / or 3 of identical heights or different can then be carried out, in a known manner, as the show Figures 1 and 3, by bolting or screwing at the pads 21, 31. The number of screws or bolts depends on the stresses to which the assemblies are subjected.

    Un mode de réalisation d'une structure avec emboítement de profils de hauteurs différentes peut être envisagé pour la réalisation de toitures ou de façades sans création d'un décalage de niveau.An embodiment of a structure with interlocking of profiles of different heights can be considered for the realization of roofs or facades without creating a level shift.

    La fixation des profils 2, 3 conformes à l'invention sur les poutres d'infrastructure 1 peut être réalisée par mise en oeuvre de boulons ou de vis auto-taraudeuses fixant l'extrémité desdits profils 2, 3 à cette dite poutre 1.The fixing of the profiles 2, 3 in accordance with the invention on the infrastructure beams 1 can be produced by using bolts or self-tapping screws fixing the end of said profiles 2, 3 to said beam 1.

    Comme le montre la figure 1 des dessins annexés, une continuité sur appuis est obtenue par un chevauchement des profils 2 et 3 avec prolongation de part et d'autre des poutres 1 d'infrastructure. Le degré de raideur d'assemblage peut être obtenu, soit en variant la longueur des débords desdits profils sur les poutres 1, soit en variant les hauteurs des profils 2 et 3.As shown in Figure 1 of the accompanying drawings, a continuity on supports is obtained by an overlap of profiles 2 and 3 with extension on either side of the infrastructure beams 1. Degree assembly stiffness can be obtained, either by varying the length of the overhangs of said profiles on the beams 1, either by varying the heights of the profiles 2 and 3.

    La figure 2 des dessins annexés représente un montage de profils 2, dans lequel lesdits profils 2 sont aboutés au niveau de leur appui sur les poutres 1, le liaisonnement entre les profils 2 étant assuré par l'intermédiaire d'une pièce d'appui et de fixation sur les poutres 1, non représentée. Figure 2 of the accompanying drawings shows an assembly of profiles 2, in which said profiles 2 are butted at the level of their support on the beams 1, the connection between the profiles 2 being ensured by through a support and fixing piece on the beams 1, not represented.

    Selon une autre caractéristique de l'invention, chaque profil 2 peut être pourvu, dans les travées les plus sollicitées, d'un profil de renforcement (3, ou autre) de longueur variable en fonction du renforcement recherché. Un tel renforcement peut être réalisé tout en conservant l'alignement de la plage des profils, en agissant uniquement sur leur longueur et sur leur hauteur.According to another characteristic of the invention, each profile 2 can be provided, in the most stressed spans, with a profile of reinforcement (3, or other) of variable length depending on the reinforcement sought. Such reinforcement can be achieved while maintaining the alignment of the range of profiles, acting only on their length and their height.

    La figure 5 des dessins annexés représente une application de l'invention, dans laquelle un profil 2 est pourvu d'une portion de profil 2', appelée caisson, fixée sous ses semelles 25, par l'intermédiaire des semelles 25' de cette portion de profil 2' au moyen de vis auto-taraudeuses 4 ou analogues. Un tel montage permet l'accrochage de diverses charges telles que des tuyauteries ou des canalisations dans des caissons profilés.Figure 5 of the accompanying drawings shows an application of the invention, in which a profile 2 is provided with a profile portion 2 ', called box, fixed under its soles 25, via the soles 25 'of this profile portion 2' by means of self-tapping screws 4 or like. Such an assembly allows the attachment of various loads such as pipes or conduits in profiled boxes.

    Selon une autre caractéristique de l'invention et comme le montre la figure 6 des dessins annexés, chaque extrémité des éléments profilés 2 et 3 est avantageusement pourvue, outre de perçages techniques 5 à 7 assurant la continuité entre deux éléments profilés 2 et/ou 3, de deux perçages supplémentaires 8 et 9, respectivement de plus grand diamètre et de plus faible diamètre, le perçage 8 étant destiné à permettre le passage d'un écrou ou d'une tête de vis et le perçage 9 étant destiné au passage d'une tige filetée de vis, les différents perçages 5 à 9 étant disposés de manière symétrique entre eux sur chaque extrémité. Ainsi, il est possible de réaliser, par exemple, le montage d'un premier élément profilé 2 ou 3 sur un support (non représenté) par l'intermédiaire d'une vis ou d'un boulon fixé dans le perçage 9 dudit premier élément profilé 2 ou 3, le deuxième élément profilé 2 ou 3 pouvant être superposé sur l'extrémité du premier profilé 2 ou 3 avec correspondance de leurs perçages 5 à 9 avec les perçages 9 à 5 du premier profilé, le perçage 8 de plus grand diamètre du deuxième élément profilé 2 ou 3 se superposant à la tête de vis ou autre, ayant servi à la fixation de l'extrémité du premier élément profilé 2 ou 3 en collaboration avec le perçage de plus petit diamètre 9 de ladite extrémité.According to another characteristic of the invention and as the shows Figure 6 of the accompanying drawings, each end of the elements profiles 2 and 3 is advantageously provided, in addition to technical holes 5 to 7 ensuring continuity between two profiled elements 2 and / or 3, of two additional holes 8 and 9, respectively of larger diameter and smaller diameter, the hole 8 being intended to allow passage of a nut or of a screw head and the hole 9 being intended for the passage of a screw threaded rod, the different holes 5 to 9 being arranged so symmetrical between them on each end. So it is possible to realize, for example, the mounting of a first profiled element 2 or 3 on a support (not shown) by means of a screw or bolt fixed in the drilling 9 of said first profiled element 2 or 3, the second profiled element 2 or 3 can be superimposed on the end of the first profile 2 or 3 with correspondence of their holes 5 to 9 with holes 9 to 5 of the first profile, the hole 8 of larger diameter of the second element profile 2 or 3 superimposed on the screw head or other, having been used for fixing the end of the first profiled element 2 or 3 in collaboration with the smaller diameter bore 9 of said end.

    Un tel mode de réalisation des extrémités des éléments profilés 2 et 3 permet d'assurer une continuité de fixation de ces éléments profilés lors de leur pose ainsi qu'un montage partiel au sol. Leur fixation définitive sur les supports de la structure ne nécessitent, de ce fait, pas de manipulation complémentaire et/ou de démontage partiel sur leur lieu d'assemblage. Such an embodiment of the ends of the profiled elements 2 and 3 ensures continuity of attachment of these profiled elements during their installation as well as a partial assembly on the ground. Their final fixation on the supports of the structure do not therefore require additional handling and / or partial disassembly at their location assembly.

    Enfin, du fait d'une disposition parfaitement symétrique des perçages 5 à 9, les éléments profilés 2 et 3 ne présentent plus de sens de pose imposé et sont ainsi plus faciles à mettre en oeuvre.Finally, due to a perfectly symmetrical arrangement of the holes 5 to 9, the profiled elements 2 and 3 no longer have a sense of pose imposed and are thus easier to implement.

    Les profils 2 et 3 conforme à l'invention, qui sont réalisés par profilage d'une bande de tôle, permettent une adaptation des performances mécaniques aux conditions d'emploi du produit. En effet, du fait de leur forme géométrique et, en particulier, des dimensions des parties constitutives, ils peuvent être optimalisés pour assurer les performances mécaniques nécessaires, tant au niveau de la résistance et de la stabilité, que de la rigidité, tout en étant d'un poids relativement faible.Profiles 2 and 3 according to the invention, which are produced by profiling of a sheet metal strip, allow performance adaptation mechanical to the conditions of use of the product. Indeed, because of their geometric shape and, in particular, the dimensions of the parts they can be optimized to ensure performance mechanical requirements, both in terms of strength and stability, and rigidity, while being relatively light in weight.

    Par ailleurs, ces profils permettent un assemblage facile en profils multiples, c'est-à-dire par emboítement de profils de hauteurs différentes, sans création de différences de niveaux ou de décalages. En outre, la possibilité d'emboítement permet d'assurer une continuité de profils ou un renforcement au niveau d'un ou de plusieurs profils.In addition, these profiles allow easy assembly in multiple profiles, that is to say by nesting height profiles different, without creating differences in levels or offsets. In in addition, the possibility of nesting ensures continuity of profiles or a reinforcement at the level of one or more profiles.

    Enfin, du fait même de la constitution des profils à partir de tôles pliées, leur assemblage avec d'autres profils, sur un support ou avec des moyens d'écartement ou de liaisonnement, est facilité par la possibilité de mise en oeuvre de vis auto-taraudeuses ou de boulons.Finally, due to the very constitution of the profiles from folded sheets, their assembly with other profiles, on a support or with spacing or bonding means, is facilitated by the possibility for implementing self-tapping screws or bolts.

    Grâce à l'invention, il est possible de réaliser des structures de support offrant des performances adaptées aux conditions d'emploi spécifiques.Thanks to the invention, it is possible to produce structures of support offering performance adapted to the conditions of use specific.

    Ainsi, la forme géométrique des profils assure les performances mécaniques optimales, tant au niveau de la résistance et de la stabilité que de la rigidité, par rapport au poids de la matière utilisée. En outre, un assemblage de profils de hauteurs différentes est facilité, de même que la réalisation d'une continuité ou d'un renforcement par emboítement, ce avec utilisation de hauteurs de profils identiques ou différentes.Thus, the geometric shape of the profiles ensures performance optimal mechanical strength, both in terms of strength and stability stiffness, relative to the weight of the material used. In addition, a assembly of profiles of different heights is facilitated, as is the realization of a continuity or a reinforcement by interlocking, this with use of identical or different profile heights.

    Enfin, l'assemblage de la structure conforme à l'invention est facilité par l'utilisation possible de simples vis auto-taraudeuses et la géométrie des profils favorise l'accrochage de charges diverses.Finally, the assembly of the structure according to the invention is facilitated by the possible use of simple self-tapping screws and the profile geometry favors the attachment of various loads.

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the modes of embodiment described and shown in the accompanying drawings. Modifications remain possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without leaving for as much of the protection field of the invention.
