Description

La présente invention concerne une structure démontable pour bâtiment de type métallo-textile. Le document GB 1 507 136 A décrit une telle structure.The present invention relates to a dismountable structure for a building of metallo-textile type. The document GB 1 507 136 A describes such a structure.

Dans la présente invention, on entend par « bâtiment démontable » un bâtiment à usage temporaire ou permanent, tel que, par exemple, un hangar, un chapiteau pour évènement sportif, une tente d'exposition, ou encore un bâtiment pour le stockage industriel.In the present invention, the term "demountable building" means a building for temporary or permanent use, such as, for example, a hangar, a marquee for sports events, an exhibition tent, or a building for industrial storage.

Une structure démontable 1 de l'art antérieur est représentée à la figure 1.A dismountable structure 1 of the prior art is shown in FIG. figure 1 .

Cette structure comprend classiquement un ensemble de poteaux 3 supportant une charpente 5 de toiture. Les poteaux délimitent typiquement des murs, non représentés.This structure conventionally comprises a set of posts 3 supporting a roof structure 5. The posts typically delimit walls, not shown.

La toiture consiste généralement en une toile textile par exemple en polychlorure de vinyle (non représentée), que l'on fixe sur la charpente pour se protéger des intempéries.The roof usually consists of a textile fabric for example polyvinyl chloride (not shown), which is fixed on the frame to protect against the weather.

La charpente 5 comprend une pluralité de pannes 7 et de fermes 9. Les pannes 7 et les fermes 9 sont par exemple métalliques, notamment en acier ou en aluminium. Les fermes 9, encore appelées « arbalétriers », sont positionnées selon une direction sensiblement transverse auxdites pannes.The frame 5 comprises a plurality of purlins 7 and farms 9. The purlins 7 and the trusses 9 are for example metal, especially steel or aluminum. The trusses 9, also called "rafters" are positioned in a direction substantially transverse to said purlins.

Les pannes 7 sont par exemple sensiblement équidistantes les unes des autres dans le sens de la largeur de la structure 1. Les fermes 9 sont quant à elles réparties sensiblement à équidistance les unes des autres dans le sens de la profondeur de la structure 1. Elles s'étendent le long de la largeur de la structure 1, reliant deux poteaux 3 entre eux. Chaque panne 7 est reliée au niveau de ses extrémités 7a, 7b à deux fermes 9 de façon à ce que, lorsque les pannes sont assemblées aux fermes de la structure, lesdites pannes s'étendent sensiblement sur toute la profondeur de la structure.The failures 7 are for example substantially equidistant from each other in the direction of the width of the structure 1. The trusses 9 are in turn distributed substantially equidistant from each other in the direction of the depth of the structure 1. They extend along the width of the structure 1, connecting two posts 3 between them. Each failure 7 is connected at its ends 7a, 7b to two farms 9 so that, when the failures are assembled to the farms of the structure, said failures extend substantially over the entire depth of the structure.

On se réfère à la figure 2 qui est une vue en coupe longitudinale partielle de la structure 1 de la figure 1, centrée sur une panne 7 et illustrant la liaison entre une panne 7 et deux fermes 9.We refer to the figure 2 which is a partial longitudinal sectional view of structure 1 of the figure 1 centered on a failure 7 and illustrating the connection between a fault 7 and two farms 9.

Afin d'assurer la liaison entre la panne 7 et les fermes 9, chaque ferme 9 comprend une accroche-panne 11, soudée ou boulonnée sur ladite ferme, tandis que la panne 7 comprend un about 13 fixé par soudage aux deux extrémités 7a, 7b de la panne. Alternativement la panne peut comprendre un crochet boulonné au niveau de chacune de ses extrémités.In order to ensure the connection between the failure 7 and the trusses 9, each truss 9 comprises a catch-tip 11, welded or bolted to said truss, while the trough 7 comprises a joint 13 fixed by welding at the two ends 7a, 7b of the breakdown. Alternatively the failure may include a hook bolted at each of its ends.

Lors du montage de la structure 1, la panne 7 est fixée aux fermes 9 en insérant les abouts 13 ou crochets de chaque panne 7 dans les accroche-pannes 11 des fermes 9. Cette étape du montage de la structure démontable se révèle être particulièrement complexe et fastidieuse. Il en va de même lors du démontage de cette structure.When mounting the structure 1, the fault 7 is attached to the trusses 9 by inserting the ends 13 or hooks of each fault 7 in the catch-failures 11 farms 9. This step of mounting the removable structure proves to be particularly complex and tedious. It's the same when dismantling this structure.

De plus, la fixation d'une panne 7 sur les deux fermes 9 avoisinantes nécessite que les pannes et fermes soient équipées des accroche-pannes 11 et des abouts 13 ou crochets préalablement à l'étape de montage de la structure 1.In addition, the fixing of a fault 7 on the two neighboring farms 9 requires that the purlins and farms are equipped with the catch-purlins 11 and abouts 13 or hooks prior to the mounting step of the structure 1.

La conception des pannes et des fermes selon l'art antérieur nécessite ainsi une première étape de fabrication des pannes et fermes et une deuxième étape d'assemblage de ces pannes et fermes avec leurs systèmes d'attache respectifs.The design of failures and trusses according to the prior art thus requires a first step of manufacturing faults and farms and a second step of assembling these faults and farms with their respective fastening systems.

Cela induit par conséquent un temps et un coût de production relativement important pour le fabricant de telles pannes et fermes.This therefore leads to a relatively high production time and cost for the manufacturer of such failures and farms.

Par ailleurs, les accroche-pannes montées sur les fermes sont aujourd'hui adaptées pour coopérer avec des abouts ou crochets d'un type particulier, rendant généralement incompatible le montage de pannes d'un fabricant avec les fermes d'un autre fabricant.Furthermore, the fault-catchers mounted on farms are now adapted to cooperate with abouts or hooks of a particular type, making it generally incompatible the assembly of faults of a manufacturer with the farms of another manufacturer.

D'autre part, le fait que les pannes et fermes comprennent dès leurs fabrications leurs systèmes d'attache respectifs complexifie leurs transports, en ce qu'il est nécessaire de protéger les systèmes d'attaches qui se trouvent en saille des pannes et des fermes.On the other hand, the fact that the breakdowns and farms understand from their manufacture their respective fastening systems complicates their transport, in that it is necessary to protect the fastening systems that are in the wake of failures and farms .

Enfin, lorsque la structure est assemblée, il a été constaté la présence d'un régime vibratoire engendré par le vent, entraînant un desserrage des boulons des accroche-pannes, ce qui peut se révéler dangereux pour le maintien de la structure notamment lors d'intempéries.Finally, when the structure is assembled, it has been found the presence of a vibratory regime generated by the wind, resulting in loosening of the bolts of the catch-purlins, which can be dangerous for the maintenance of the structure including when severe weather.

La présente invention vise à pallier les inconvénients induits par les structures de l'art antérieur, et se rapporte à cet effet à une structure démontable pour bâtiment de type métallo-textile, comprenant :

  • une pluralité de pannes s'étendant selon une direction sensiblement parallèle à un axe longitudinal de la structure, au moins une desdites pannes comprenant au moins deux rainures transversales ;
  • une pluralité de fermes s'étendant dans une direction sensiblement transverse auxdites pannes, au moins une desdites fermes comprenant au moins une rainure longitudinale ;
au moins une desdites pannes étant fixée à au moins une desdites fermes par un système d'attache adapté pour maintenir ladite panne sur ladite ferme,
ladite structure démontable étant remarquable en ce que ledit système d'attache comprend :
  • un plateau de support de panne conformé pour supporter au moins une extrémité de ladite panne,
  • un premier cadre de maintien de la panne, agencé au niveau d'un premier bord dudit plateau, apte à pénétrer ladite panne,
  • un deuxième cadre de maintien de la panne, agencé au niveau d'un deuxième bord dudit plateau, apte à pénétrer ladite ferme,
ledit plateau et lesdits cadres définissant une section sensiblement en forme de U, et les premier et deuxième cadres de maintien dudit système d'attache pénétrant respectivement les rainures desdites panne et ferme.The present invention aims at overcoming the disadvantages induced by the structures of the prior art, and relates for this purpose to a demountable structure for a building of metallo-textile type, comprising:
  • a plurality of failures extending in a direction substantially parallel to a longitudinal axis of the structure, at least one of said failures comprising at least two transverse grooves;
  • a plurality of trusses extending in a direction substantially transverse to said purlins, at least one of said trusses comprising at least one longitudinal groove;
at least one of said failures being attached to at least one of said trusses by a fastening system adapted to maintain said failure on said farm,
said removable structure being remarkable in that said fastening system comprises:
  • a failure support plate shaped to support at least one end of said failure,
  • a first maintenance frame of the failure, arranged at a first edge of said plate, adapted to penetrate said failure,
  • a second failure maintenance frame, arranged at a second edge of said plate, adapted to penetrate said farm,
said plate and said frames defining a substantially U-shaped section, and the first and second holding frames of said fastening system respectively penetrating the grooves of said tip and closes.

Ainsi, en prévoyant une telle structure comprenant un tel système d'attache selon l'invention, on réalise de façon extrêmement simple l'assemblage entre les pannes et les fermes d'une structure. On évite par conséquent d'avoir à boulonner, à riveter, à souder voir à coller les pannes et les fermes entre elles comme c'est le cas pour les systèmes d'attache de l'art antérieur, ce qui permet d'optimiser le temps de construction de la structure. Cela trouve un intérêt d'autant plus important puisque le système d'attache selon l'invention équipe les structures de bâtiments démontables. Le temps et le procédé de démontage de ces structures se trouvent par conséquent également largement réduit et simplifié par rapport aux systèmes d'assemblage permanents de l'art antérieur.Thus, by providing such a structure comprising such a fastening system according to the invention, it is extremely simple to assemble the failures and farms of a structure. It therefore avoids having to bolt, rivet, solder or glue failures and trusses together as is the case for fastening systems of the prior art, which allows to optimize the construction time of the structure. This finds an even more important interest since the fastening system according to the invention equips the structures of demountable buildings. The time and method of disassembly of these structures are therefore also greatly reduced and simplified compared with the permanent joining systems of the prior art.

Par ailleurs, en évitant le boulonnage des pannes et des fermes entre elles, on augmente la résistance de la structure aux régimes vibratoires engendrés par le vent en ce que le risque de desserrage des pannes sur les fermes est à présent supprimé.In addition, by avoiding the bolting of faults and trusses between them, the resistance of the structure to the vibration regimes generated by the wind is increased in that the risk of loosening faults on farms is now eliminated.

D'autre part, le fait que le système d'attache présente une géométrie définissant une section sensiblement en forme de U dont chacun des cadres pénètrent la panne et la ferme sur laquelle la panne est fixée permet à ladite panne de transmettre à ladite ferme les efforts de compression, de cisaillement et de torsion, ce qui augmente la résistance mécanique de la structure.On the other hand, the fact that the fastening system has a geometry defining a substantially U-shaped section each of the frames penetrate the fault and the farm on which the fault is fixed allows said failure to transmit to said farm the compression, shear and torsion forces, which increases the mechanical strength of the structure.

Selon des caractéristiques toutes optionnelles de la structure démontable de l'invention :

  • l'angle entre le plateau de support et au moins un desdits cadres du système d'attache est sensiblement égal à 90° ;
  • en variante, l'angle entre le plateau de support et au moins un desdits cadres du système d'attache est sensiblement égal à 85°, ce qui permet d'améliorer la fixation sur une ferme, du système d'attache de l'invention ;
  • le système d'attache peut comprendre deux cadres supplémentaires agencés respectivement au niveau de troisième et quatrième bords dudit plateau, lesdits cadres supplémentaires définissant avec ledit plateau une section sensiblement en forme de U s'étendant dans une direction transverse à la section en forme de U définie par ledit plateau et par les cadres de maintien de la panne, et s'étendant selon un sens opposé à celui défini par la section en forme de U définie par ledit plateau et par les cadres de maintien de la panne, relativement au plateau de support de panne. Cela permet avantageusement de renforcer la tenue mécanique du système d'attache lorsque ledit système équipe une structure de bâtiment démontable.
  • le système d'attache selon l'invention est de préférence métallique ;
  • la rainure transversale de la panne de la structure démontable selon l'invention est profilée au niveau d'au moins une des extrémités de ladite panne ;
  • de même, la rainure longitudinale de la ferme de la structure démontable selon l'invention est profilée au niveau d'au moins une des extrémités de ladite ferme ;
  • le système d'attache comprend deux cadres supplémentaires agencés respectivement au niveau de troisième et quatrième bords du plateau, lesdits cadres supplémentaires définissant avec ledit plateau une section sensiblement en forme de U s'étendant dans une direction transverse à la section en forme de U définie par ledit plateau et par les cadres de maintien de la panne, et s'étendant selon un sens opposé à celui défini par la section en forme de U définie par ledit plateau et par les cadres de maintien de la panne, relativement au plateau de support de panne, la distance entre une paroi interne du deuxième cadre de maintien et une paroi latérale des cadres supplémentaires est avantageusement comprise entre 1,5 fois et 2,5 fois l'épaisseur de la paroi latérale de la ferme, ce qui permet de conférer à la structure de bâtiment démontable une excellente tenue mécanique au niveau du système d'attache de l'invention.
According to all the optional features of the dismountable structure of the invention:
  • the angle between the support plate and at least one of said frames of the fastening system is substantially equal to 90 °;
  • alternatively, the angle between the support plate and at least one of said frames of the fastening system is substantially equal to 85 °, which improves the attachment on a farm, the fastening system of the invention ;
  • the fastening system may comprise two additional frames arranged respectively at the third and fourth edges of said plate, said additional frames defining with said plate a substantially U-shaped section extending in a direction transverse to the U-shaped section defined by said tray and by the maintenance frames of the fault, and extending in a direction opposite to that defined by the U-shaped section defined by said plate and the maintenance frames of the failure, relative to the tray of fault support. This advantageously makes it possible to reinforce the mechanical strength of the fastening system when said system equips a demountable building structure.
  • the fastening system according to the invention is preferably metallic;
  • the transverse groove of the breakdown of the dismountable structure according to the invention is profiled at at least one of the ends of said failure;
  • likewise, the longitudinal groove of the farm of the demountable structure according to the invention is profiled at at least one of the ends of said farm;
  • the fastening system comprises two additional frames arranged respectively at third and fourth edges of the plate, said additional frames defining with said plate a substantially U-shaped section extending in a direction transverse to the U-shaped section defined by said platen and by the fault-retaining frames, and extending in a direction opposite to that defined by the U-shaped section defined by said platen and by the retaining frames of the failure, relative to the support platen of failure, the distance between an inner wall of the second holding frame and a side wall of the additional frames is advantageously between 1.5 times and 2.5 times the thickness of the side wall of the farm, which allows to confer the demountable building structure excellent mechanical strength at the attachment system of the invention.

On se réfère aux figures 3 et 4 auxquelles sont respectivement représentés le système d'attache 15 selon un premier mode de réalisation de l'invention et une structure démontable 17 comprenant le système d'attache 15.We refer to Figures 3 and 4 which are respectively represented the fastening system 15 according to a first embodiment of the invention and a removable structure 17 comprising the fastening system 15.

Le système d'attache 15 est destiné à assurer l'assemblage entre une panne et une ferme d'une structure de bâtiment démontable de type métallo-textile. Le système d'attache 15 est de préférence métallique, par exemple en acier ou en aluminium.The fastening system 15 is intended to ensure the assembly between a breakdown and a farm of a demountable building structure of metallo-textile type. The attachment system 15 is preferably metal, for example steel or aluminum.

Selon l'invention, le système d'attache 15 comprend un plateau 19 adapté pour supporter une extrémité 21a d'une panne 21 de la structure démontable 17.According to the invention, the fastening system 15 comprises a plate 19 adapted to support an end 21a of a failure 21 of the removable structure 17.

Le plateau 19 présente par exemple une forme sensiblement rectangulaire comprenant quatre bords 19a, 19b, 19c, 19d.The plate 19 has for example a substantially rectangular shape comprising four edges 19a, 19b, 19c, 19d.

Au niveau du premier bord 19a du plateau 19 est agencé un premier cadre 23 de maintien de la panne 21.At the first edge 19a of the plate 19 is arranged a first frame 23 for maintaining the fault 21.

Le cadre 23 s'étend sensiblement sur toute la longueur du premier bord 19a.The frame 23 extends substantially over the entire length of the first edge 19a.

Bien entendu, ce cadre peut s'étendre sur une partie seulement de la longueur du premier bord 19a.Of course, this frame may extend over only a portion of the length of the first edge 19a.

Le premier cadre 23 définit un angle d'environ 90° avec le plateau 19.The first frame 23 defines an angle of approximately 90 ° with the plate 19.

Le premier cadre 23 est adapté pour pénétrer la panne 21, comme on va le voir dans la suite de la description.The first frame 23 is adapted to penetrate the failure 21, as will be seen in the following description.

Au niveau du deuxième bord 19b du plateau 19 est agencé un deuxième cadre 25 de maintien de la panne 21, comprenant une paroi interne 25a et une paroi externe 25b.At the second edge 19b of the plate 19 is arranged a second support frame 25 of the fault 21, comprising an inner wall 25a and an outer wall 25b.

Le cadre 25 s'étend sensiblement sur toute la longueur du deuxième bord 19b.The frame 25 extends substantially over the entire length of the second edge 19b.

Bien entendu, ce cadre peut s'étendre sur une partie seulement de la longueur du deuxième bord 19b.Of course, this frame may extend over only a portion of the length of the second edge 19b.

Le deuxième cadre 25 définit également un angle d'environ 90° avec le plateau 19.The second frame 25 also defines an angle of approximately 90 ° with the plate 19.

Le deuxième cadre 25 est quant à lui adapté pour pénétrer une ferme 27 de la structure démontable 17.The second frame 25 is adapted to penetrate a farm 27 of the removable structure 17.

Le plateau 19 du système d'attache 15 définit, avec les premier et deuxième cadres 23, 25 de maintien de la panne, une section sensiblement en forme de U.The plate 19 of the fastening system 15 defines, with the first and second frames 23, 25 of maintaining the failure, a substantially U-shaped section.

Lorsque le système d'attache 15 est monté sur la structure démontable 17, la section en forme de U s'étend parallèlement à un axe longitudinal de la panne 21. Cette section en forme de U s'étend par ailleurs vers le haut du plateau 19, lorsque l'on regarde le système d'attache 15 tel qu'il est représenté à la figure 3.When the fastening system 15 is mounted on the demountable structure 17, the U-shaped section extends parallel to a longitudinal axis of the tip 21. This U-shaped section also extends to the top of the plate 19, when looking at the fastening system 15 as shown in FIG. figure 3 .

Lorsque le système d'attache 15 pénètre les panne 21 et ferme 27, il permet de maintenir ladite panne sur ladite ferme, comme illustré à la figure 2.When the fastening system 15 penetrates the failure 21 and closes 27, it allows to maintain said failure on said farm, as shown in FIG. figure 2 .

Le système d'attache comprend en outre deux cadres 29, 31 supplémentaires, respectivement agencés au niveau des troisième et quatrième bords 19c, 19d du plateau 19.The fastening system further comprises two additional frames 29, 31, respectively arranged at the third and fourth edges 19c, 19d of the plate 19.

Les cadres 29, 31 s'étendent respectivement sensiblement sur toute la longueur des troisième et quatrième bords 19c, 19d du plateau 19, mais peuvent tout à fait s'étendre sur une partie seulement de la longueur des troisième et quatrième bords 19c, 19d.The frames 29, 31 respectively extend substantially the entire length of the third and fourth edges 19c, 19d of the plate 19, but may extend quite a portion only of the length of the third and fourth edges 19c, 19d.

Le cadre 29, respectivement le cadre 31, comprend deux parois latérales 29a, 29b, respectivement 31a, 31b.The frame 29, respectively the frame 31, comprises two side walls 29a, 29b, respectively 31a, 31b.

Les cadres 29, 31 définissent également chacun un angle d'environ 90° avec le plateau 19.The frames 29, 31 also each define an angle of about 90 ° with the plate 19.

Le plateau 19 du système d'attache 15 définit, avec les cadres supplémentaires 29, 31, une section sensiblement en forme de U.The plate 19 of the fastening system 15 defines, with the additional frames 29, 31, a substantially U-shaped section.

La section en forme de U définie par les cadres supplémentaires 29, 31 s'étend dans une direction transverse à la section en forme de U définie par ledit plateau et par les cadres 23, 25 de maintien de la panne, de sorte que lorsque le système d'attache 15 est monté sur la structure démontable 17, la section en forme de U définie par les cadres supplémentaires 29, 31 s'étend transversalement à l'axe longitudinal de la panne 21.The U-shaped section defined by the additional frames 29, 31 extends in a direction transverse to the U-shaped section defined by said tray and the defect maintenance frames 23, 25 so that when the fastening system 15 is mounted on the demountable structure 17, the U-shaped section defined by the additional frames 29, 31 extends transversely to the longitudinal axis of the tip 21.

La section en forme de U définie par les cadres supplémentaires 29, 31 s'étend selon un sens opposé à celle définie par les cadres 23, 25 de maintien de la panne, relativement au plateau de support de panne. En d'autres termes, la section en forme de U définie par les cadres supplémentaires 29, 31 s'étend vers le bas du plateau 19, lorsque l'on regarde le système d'attache 15 tel qu'il est représenté à la figure 3.The U-shaped section defined by the additional frames 29, 31 extends in a direction opposite to that defined by the failure holding frames 23, 25, relative to the failure support tray. In other words, the U-shaped section defined by the additional frames 29, 31 extends towards the bottom of the plate 19, when one looks at the fastening system 15 as represented in FIG. figure 3 .

Préférentiellement, la distance entre la paroi interne 25a du deuxième cadre 25 et la paroi latérale 29a, respectivement 31a, du cadre supplémentaire 29, respectivement 31, est comprise entre 1,5 fois et 2,5 fois l'épaisseur de la paroi latérale 37, 39 de la ferme 27 (visible à la figure 7). Cette plage de valeurs permet de conférer à la structure de bâtiment démontable une excellente tenue mécanique lorsque le système d'attache équipe la structure, tout en permettant un montage aisé du système d'attache dans la structure.Preferably, the distance between the inner wall 25a of the second frame 25 and the side wall 29a, respectively 31a, of the additional frame 29, respectively 31, is between 1.5 times and 2.5 times the thickness of the side wall 37 , 39 from Farm 27 (visible at figure 7 ). This range of values makes it possible to give the demountable building structure excellent mechanical strength when the fastening system equips the structure, while allowing easy mounting of the fastening system in the structure.

La présente invention concerne une structure démontable pour bâtiment de type métallo-textile, du type de celle mentionnée dans le préambule de la présente description.The present invention relates to a dismountable structure for a building of metallo-textile type, of the type mentioned in the preamble of the present description.

A cet effet, la structure démontable de l'invention comprend une pluralité de pannes 21 et de fermes 27 réparties dans la structure démontable de manière équivalente à la représentation des structures de l'art antérieur faite dans le préambule de la description en référence à la figure 1.For this purpose, the dismountable structure of the invention comprises a plurality of purlins 21 and trusses 27 distributed in the demountable structure in a manner equivalent to the representation of the structures of the prior art made in the preamble of the description with reference to FIG. figure 1 .

Les pannes 21 et les fermes 27 sont par exemple métalliques, notamment en acier ou en aluminium.The purlins 21 and the trusses 27 are for example metal, especially steel or aluminum.

Les pannes 21 s'étendent selon une direction sensiblement parallèle à un axe longitudinal de la structure, et les fermes 27 s'étendent dans une direction sensiblement transverse auxdites pannes 21.The purlins 21 extend in a direction substantially parallel to a longitudinal axis of the structure, and the trusses 27 extend in a direction substantially transverse to said purlins 21.

Selon l'invention, en référence aux figures 5 à 7, la fixation des pannes 21 sur les fermes 27 est assurée par le système d'attache 15 de l'invention.According to the invention, with reference to Figures 5 to 7 , fixing the purlins 21 on the trusses 27 is provided by the attachment system 15 of the invention.

Pour ce faire, une panne 21 de la structure démontable comprend deux rainures 33. Les rainures 33 sont de préférence transversales, par rapport à un axe longitudinal de la panne 21.To do this, a breakdown 21 of the demountable structure comprises two grooves 33. The grooves 33 are preferably transverse, with respect to a longitudinal axis of the tip 21.

Les rainures 33 transversales sont préférentiellement mais non limitativement profilées au niveau des extrémités 21a, 21b de la panne 21.The transverse grooves 33 are preferably but not limitatively profiled at the ends 21a, 21b of the tip 21.

De la même manière, une ferme 27 de la structure démontable comprend au moins une rainure 35. La rainure 35 est de préférence longitudinale, c'est-à-dire sensiblement parallèle à un axe longitudinal de la ferme 27.In the same way, a firm part 27 of the dismountable structure comprises at least one groove 35. The groove 35 is preferably longitudinal, that is to say substantially parallel to a longitudinal axis of the farm 27.

Les rainures 35 longitudinales sont préférentiellement mais non limitativement profilées au niveau des extrémités 27a, 27b de la ferme 27 (aux figures 5 et 7, uniquement l'extrémité 27a de la ferme est visible).The longitudinal grooves 35 are preferably but not limitatively profiled at the ends 27a, 27b of the farm 27 (at the Figures 5 and 7 only the end 27a of the farm is visible).

Les rainures 35 longitudinales sont par exemple agencées sur chaque paroi latérale 37, 39 de la ferme 27.The longitudinal grooves 35 are for example arranged on each side wall 37, 39 of the farm 27.

Les rainures 33 et 35 sont dimensionnées pour recevoir respectivement les premier et deuxième cadres de maintien 23, 25 du système d'attache 15, de sorte que les premier et deuxième cadres 23, 25 de maintien pénètrent respectivement les rainures 33 et 35 des panne 21 et ferme 27.The grooves 33 and 35 are dimensioned to respectively receive the first and second holding frames 23, 25 of the fastening system 15, so that the first and second holding frames 23, 25 respectively penetrate the grooves 33 and 35 of the breakdowns 21 and closes 27.

Selon un deuxième mode de réalisation du système d'attache 15, représenté à la figure 8, le premier et le deuxième cadres 23, 25 définissent respectivement avec le plateau 19 un angle d'environ 85°.According to a second embodiment of the fastening system 15, shown in FIG. figure 8 the first and second frames 23, 25 respectively define with the plate 19 an angle of about 85 °.

Cela permet avantageusement d'améliorer le maintien du système d'attache 15 sur une ferme, lorsqu'en cours de montage de la structure de l'invention le système d'attache est positionné dans la rainure de la ferme, et avant le positionnement de la panne sur le plateau de support du système d'attache.This advantageously makes it possible to improve the maintenance of the attachment system 15 on a farm, when during assembly of the structure of the invention the attachment system is positioned in the groove of the farm, and before the positioning of the the fault on the support plate of the fastening system.

La figure 9 illustre la liaison entre une panne 21 et une ferme 27 de la structure grâce au système d'attache 15 obtenu par le deuxième mode de réalisation de l'invention. La figure 10 est une vue en coupe selon l'axe longitudinal de la panne 21 de la structure de la figure 9, centrée sur la panne 21, sur laquelle on remarque la liaison entre la panne 21 et les deux fermes 27 au moyen d'un système d'attache selon le deuxième mode de réalisation de l'invention.The figure 9 illustrates the connection between a failure 21 and a firm 27 of the structure through the fastening system 15 obtained by the second embodiment of the invention. The figure 10 is a sectional view along the longitudinal axis of the failure 21 of the structure of the figure 9 , centered on the fault 21, on which we note the connection between the fault 21 and the two farms 27 by means of a fastening system according to the second embodiment of the invention.

Le système d'attache 15 selon le premier ou deuxième mode de réalisation de l'invention est particulièrement bien adapté pour supporter une panne lorsque deux fermes sont distantes l'une par rapport à l'autre de 5 mètres environ, bien qu'il puisse tout à fait être dimensionné pour supporter une panne reliant deux fermes distantes d'une longueur supérieure ou inférieure à 5 mètres.The fastening system 15 according to the first or second embodiment of the invention is particularly well adapted to withstand a failure when two farms are spaced from each other by about 5 meters, although it can quite sized to withstand a failure connecting two distant farms of a length greater or less than 5 meters.

Grâce à la présente invention, on réalise de façon extrêmement simple l'assemblage entre les pannes et les fermes d'une structure. On évite par conséquent d'avoir à boulonner, à riveter, à souder voir à coller les pannes et les fermes entre elles comme c'est le cas pour les systèmes d'attache de l'art antérieur, ce qui permet d'optimiser le temps de construction de la structure. Cela trouve un intérêt d'autant plus important puisque le système d'attache selon l'invention est destiné à équiper les structures de bâtiments démontables. Le temps et le procédé de démontage de ces structures se trouvent par conséquent également largement réduit et simplifié par rapport aux systèmes d'assemblage permanents de l'art antérieur.Thanks to the present invention, it is extremely simple to assemble the failures and farms of a structure. It therefore avoids having to bolt, rivet, solder or glue failures and trusses together as is the case for fastening systems of the prior art, which allows to optimize the construction time of the structure. This finds an even more important interest since the fastening system according to the invention is intended to equip the structures of demountable buildings. The time and method of disassembly of these structures are therefore also greatly reduced and simplified compared with the permanent joining systems of the prior art.

Par ailleurs, en évitant le boulonnage des pannes et des fermes entre elles, on augmente la résistance de la structure aux régimes vibratoires engendrés par le vent en ce que le risque de desserrage des pannes sur les fermes est à présent supprimé.In addition, by avoiding the bolting of faults and trusses between them, the resistance of the structure to the vibration regimes generated by the wind is increased in that the risk of loosening faults on farms is now eliminated.

D'autre part, le fait que le système d'attache présente une géométrie définissant une section sensiblement en forme de U dont chacun des cadres pénètrent la panne et la ferme sur laquelle la panne est fixée permet à ladite panne de transmettre à ladite ferme les efforts de compression, de cisaillement et de torsion, ce qui augmente la résistance mécanique de la structure.On the other hand, the fact that the fastening system has a geometry defining a substantially U-shaped section each of the frames penetrate the fault and the farm on which the fault is fixed allows said failure to transmit to said farm the compression, shear and torsion forces, which increases the mechanical strength of the structure.

Comme il va de soi, la présente invention ne se limite pas aux seules formes de réalisation de ce système d'attache et de cette structure démontable, décrites ci-dessus uniquement à titre d'exemples illustratifs, mais elle embrasse au contraire toutes les variantes faisant intervenir les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention tel que défini par les revendications ci-jointes.It goes without saying that the present invention is not limited to the embodiments of this fastening system and this removable structure, described above only as illustrative examples, but it encompasses all variants involving the technical equivalents of the means described and their combinations if they fall within the scope of the invention as defined by the appended claims.
