Description

La présente invention est relative à un procédé d'assemblage de poutres de section triangulaire en vue de réaliser une structure portante d'un bâtiment.The present invention relates to a method of assembling beams of triangular section in order to produce a bearing structure of a building.

Elle vise plus particulièrement un procédé permettant de réaliser une jonction mécanique entre des poutres principales et des poutres secondaires qui ne laisse apparaître, du côté intérieur du bâtiment, aucun système de liaison.It relates more particularly to a method for making a mechanical connection between main beams and secondary beams which does not show, on the inside of the building, any connection system.

Selon un autre aspect de l'invention, elle vise une structure portante de bâtiment réalisée par l'assemblage de poutres principales et secondaires en mettant en oeuvre ce procédé d'assemblage.According to another aspect of the invention, it relates to a load bearing building structure produced by the assembly of main and secondary beams by implementing this assembly method.

De façon classique, l'assemblage de poutres en vue de réaliser une structure portante de bâtiment laisse apparaître les moyens de liaison entre ces poutres, quelle que soit la forme utilisée de ces moyens de liaison. De telles réalisations présentent donc l'inconvénient d'offrir un aspect peu esthétique à une personne située à l'intérieur du bâtiment.Conventionally, the assembly of beams to produce a load-bearing structure of the building reveals the means of connection between these beams, whatever the form used of these connecting means. Such achievements therefore have the disadvantage of providing an unattractive appearance to a person located inside the building.

En effet, les organes de fixation (soudures, rivets ou boulons) et les éventuelles pièces de liaison (plaques, etc...) nécessaires à l'assemblage de poutres sont toujours visibles de l'intérieur du bâtiment.Indeed, the fasteners (welds, rivets or bolts) and any connecting pieces (plates, etc ...) required for the assembly of beams are always visible from inside the building.

Par ailleurs, la forme et la disposition de tels assemblages doivent permettre une exécution aussi facile que possible, notamment présenter une accessibilité satisfaisante aux opérations de soudage et/ou de rivetage.Moreover, the shape and arrangement of such assemblies must allow an execution as easy as possible, including having a satisfactory accessibility to welding and / or riveting operations.

La présente invention vise donc à pallier ces inconvénients en proposant un procédé d'assemblage de poutres de section triangulaire en vue de réaliser une structure portante d'un bâtiment qui permet une exécution simple pour un résultat qui ne présente aucun système de liaison à une personne située à l'intérieur du bâtiment.The present invention therefore aims to overcome these disadvantages by proposing a method of assembling beams of triangular section in order to produce a bearing structure of a building that allows a simple execution for a result that does not present any system of connection to a person located inside the building.

A cet effet, le procédé selon l'invention d'assemblage de poutres principales et secondaires en vue de réaliser une structure portante de bâtiment, se caractérise en ce qu'il comporte les étapes suivantes :

  • on positionne à 90° l'une par rapport à l'autre lesdites poutres principales et secondaires, dont la section est triangulaire, de façon à ce que leur base soit tournée vers l'extérieur dudit bâtiment,
  • on découpe les extrémités de chaque poutre secondaire, cette découpe étant pratiquée de manière à pouvoir épouser le profil de la poutre principale sur laquelle doit être assemblée cette poutre secondaire ;
  • on positionne une plaque de liaison percée de trous sur chacune desdites extrémités ainsi préalablement découpée ;
  • on soude ladite plaque de liaison sur les côtés respectifs de ladite poutre secondaire ;
  • on pratique une ouverture supérieure sur chaque poutre secondaire, au niveau de sa base, de manière à permettre à un opérateur de fixer la poutre secondaire sur la poutre principale ;
  • sur la poutre principale, à l'endroit de l'assemblage de cette dernière avec la poutre secondaire, on réalise des trous correspondant aux trous percés sur la plaque de liaison respective ;
  • on assemble et on raccorde ladite poutre principale et la poutre secondaire à l'aide d'organes de fixation appropriés ; et
  • on fixe une plaque supérieure de recouvrement sur la base de ladite poutre secondaire de manière à masquer les ouvertures supérieures.
For this purpose, the method according to the invention for assembling main and secondary beams in order to produce a building supporting structure, is characterized in that it comprises the following steps:
  • the main and secondary beams, whose section is triangular, are positioned at 90 ° relative to each other so that their base is turned towards the outside of said building,
  • the ends of each secondary beam are cut, this cutout being made so as to be able to match the profile of the main beam on which this secondary beam must be assembled;
  • positioning a connecting plate pierced with holes on each of said ends thus cut beforehand;
  • said connecting plate is welded to the respective sides of said secondary beam;
  • an upper opening is made on each secondary beam, at its base, to allow an operator to fix the secondary beam on the main beam;
  • on the main beam, at the place of the assembly of the latter with the secondary beam, holes are made corresponding to the holes drilled on the respective connecting plate;
  • assembling and connecting said main beam and the secondary beam with appropriate fasteners; and
  • an upper cover plate is fixed on the base of said secondary beam so as to mask the upper openings.

L'invention a aussi pour objet une structure de bâtiment telle que définie par la revendication 3, dans laquelle les caractéristiques en préambule sont connues du document US-A-4 562 681.The invention also relates to a building structure as defined by claim 3, wherein the features in the preamble are known from US-A-4,562,681.

Selon le procédé selon l'invention d'assemblage de poutres en vue de réaliser la structure portante d'un bâtiment, on utilise des poutres principales 1 et des poutres secondaires 2 qui ont une section triangulaire.According to the method according to the invention for assembling beams in order to produce the supporting structure of a building, beams are used. main 1 and secondary beams 2 which have a triangular section.

Le procédé d'assemblage selon l'invention de ces poutres principales et secondaires comporte essentiellement huit étapes :The method of assembly according to the invention of these main and secondary beams essentially comprises eight steps:

Une première étape consiste à positionner à 90° l'une par rapport à l'autre les poutres (1, 2), dont la section est triangulaire, de telle manière que la base de ces dernières soit tournée vers l'extérieur et leur pointe vers l'intérieur du bâtiment dont on souhaite réaliser la structure portante.A first step is to position at 90 ° relative to each other the beams (1, 2), whose section is triangular, so that the base of the latter is turned outwards and their tip towards the interior of the building of which one wishes to realize the bearing structure.

Une seconde étape (cf. figure 1) a pour objet de préparer les poutres secondaires 2 en vue de leur assemblage sur les poutres principales 1. Pour ce faire, on découpe les extrémités de ladite poutre secondaire afin de pouvoir épouser le profil de la poutre principale sur laquelle doit être assemblée cette poutre secondaire.A second step (see Figure 1) is to prepare the secondary beams 2 for their assembly on the main beams 1. To do this, the ends of said secondary beam are cut in order to marry the profile of the beam principal on which must be assembled this secondary beam.

Une troisième étape consiste à positionner une plaque de liaison 3 sur les extrémités de ladite poutre secondaire ainsi préalablement découpée. Cette plaque de liaison est percée de trous 4 lisses en vue de recevoir des organes de fixation appropriés (rivets, vis ou analogues) pour la fixation sur la poutre principale 1.A third step consists in positioning a connecting plate 3 on the ends of said secondary beam thus previously cut. This connecting plate is pierced with smooth holes 4 to receive suitable fasteners (rivets, screws or the like) for attachment to the main beam 1.

Une quatrième étape consiste à souder la plaque de liaison 3 sur les côtés de la poutre secondaire 2.A fourth step is to weld the connecting plate 3 on the sides of the secondary beam 2.

Une cinquième étape (cf. figure 1) prévoit de pratiquer une ouverture supérieure 5 sur la poutre secondaire 2, au niveau de la base de cette dernière et à chacune de ses extrémités. Cette ouverture 5 est dimensionnée de manière à permettre à l'opérateur chargé de l'assemblage de passer son bras pour fixer la plaque de liaison 3 de la poutre secondaire 2 sur la poutre principale 1.A fifth step (see Figure 1) provides for an upper opening 5 on the secondary beam 2, at the base of the latter and each of its ends. This opening 5 is dimensioned so as to allow the operator responsible for the assembly to pass his arm to fix the connecting plate 3 of the secondary beam 2 on the main beam 1.

Pour ce faire, on prévoit une sixième étape du procédé selon l'invention (cf. figure 2) qui a pour but de préparer la poutre principale 1. A l'endroit de l'assemblage de cette dernière avec la poutre secondaire 2, on réalise des trous 6 correspondant aux trous 4 lisses percés sur la plaque de liaison 3 de ladite poutre secondaire.To do this, a sixth step of the method according to the invention is provided (see FIG. 2) which is intended to prepare the main beam 1. At the place of the assembly of the latter with the secondary beam 2, produces holes 6 corresponding to the smooth holes 4 drilled on the connecting plate 3 of said secondary beam.

La septième étape (cf. figure 3) consiste à assembler et à raccorder les poutres principale 1 et secondaire 2 à l'aide d'organes de fixation appropriés (vis, rivets, boulons, etc...).The seventh step (see Figure 3) is to assemble and connect the main beam 1 and secondary 2 using appropriate fasteners (screws, rivets, bolts, etc ...).

Enfin, la huitième étape du procédé selon l'invention (cf. figure 4) consiste à fixer une plaque supérieure de recouvrement 7 sur la base de la poutre secondaire 2 de manière à masquer les ouvertures supérieures 5. Cette plaque de recouvrement peut, par exemple, être vissée sur le dessus de la poutre secondaire.Finally, the eighth step of the method according to the invention (see FIG. 4) consists in fixing an upper cover plate 7 on the base of the secondary beam 2 so as to mask the upper openings 5. This cover plate can, for example, for example, be screwed to the top of the secondary beam.

Selon une caractéristique avantageuse de l'invention, la plaque de recouvrement 7 est encastrée dans les ouvertures supérieures 5.According to an advantageous characteristic of the invention, the cover plate 7 is embedded in the upper openings 5.

Comme représenté sur la figure 5, la plaque de recouvrement 7 est tournée vers l'extérieur du bâtiment dont on souhaite réaliser une structure portante et ne présente donc aucun problème particulier pour l'esthétique de l'ensemble.As shown in Figure 5, the cover plate 7 is facing the outside of the building which is to achieve a supporting structure and therefore presents no particular problem for the aesthetics of the assembly.

Par ailleurs, le procédé selon l'invention d'assemblage de poutres principales et secondaires, permet d'obtenir une structure portante de bâtiment qui dissimule le système de liaison entre lesdites poutres pour une personne placée à l'intérieur du bâtiment. En effet, cette personne ne voit que le profil des poutres principales et secondaires.Furthermore, the method according to the invention of assembly of main and secondary beams, provides a building supporting structure which conceals the connecting system between said beams for a person placed inside the building. Indeed, this person only sees the profile of the main and secondary beams.

Bien entendu, les poutres principales 1 et les poutres secondaires 2 ont une hauteur variable. Par exemple, la hauteur des poutres secondaires peut être supérieure, égale ou inférieure à celle des poutres principales.Of course, the main beams 1 and the secondary beams 2 have a variable height. For example, the height of the secondary beams may be greater than, equal to or less than that of the main beams.

La présente invention telle que décrite précédemment offre de multiples avantages ; notamment elle propose un procédé d'assemblage de poutres simple de mise en oeuvre et dont la structure portante de bâtiment obtenue ne présente aucun problème d'esthétique.The present invention as described above offers multiple advantages; in particular, it proposes a method of assembly of beams that is simple to implement and whose bearing structure of building obtained presents no aesthetic problem.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes dans le cadre des revendications annexées.It remains understood that the present invention is not limited to the embodiments described and shown above, but encompasses all variants within the scope of the appended claims.
