DOMAINE D'APPLICATION DE L'INVENTIONFIELD OF APPLICATION OF THE INVENTION
La présente invention concerne un dispositif de tension périphérique pour membrane textile, servant à la tendre dans les 2 directions à une valeur souhaitée, sur un cadre rigide. Le domaine d'application préférentiel est l'architecture textile (façades textiles, toitures, vélums, plafonds tendus, cloisons, etc) The present invention relates to a peripheral tension device for a textile membrane, serving to tension it in 2 directions to a desired value on a rigid frame. The preferred field of application is textile architecture (textile facades, roofs, awnings, stretch ceilings, partitions, etc.)
DESCRIPTION DE L'ART ANTÉRIEURDESCRIPTION OF THE PRIOR ART
On connaît les parois planes en toile tendue servant de façade, de cloison ou de plafond. Un des défauts habituels de ce type de parois est le manque de tension uniforme dans les 2 directions, 10 ce qui provoque des plis disgracieux ou bien un manque général de tension qui amène un comportement instable sous l'action du vent. The flat walls made of stretched canvas are known as facades, partitions or ceilings. One of the usual defects of this type of wall is the lack of uniform tension in both directions, which causes unsightly folds or a general lack of tension which causes unstable behavior under the action of the wind.
Par ailleurs, les organes de tension utilisés jusqu'à présent, souvent peu esthétiques et imposants, ne garantissent pas la pérennité des tensions dans le temps. Moreover, the tensioning devices used up to now, often unsightly and imposing, do not guarantee the durability of tensions over time.
Les organes de tension utilisés dans l'art antérieur sont ou bien un sandow périphérique passant dans des oeillets, ou bien des tendeurs mécaniques (tige filetée, ridoir, etc) ou des ressorts en traction, par l'intermédiaire d'un jonc rigide passé dans un fourreau périphérique intégré à la membrane textile, ou bien un cadre rigide pinçant le périmètre de la membrane en lui donnant une certaine tension, etc. Ces organes de tension de l'art antérieur ont pour caractéristique commune d'être encombrants, visibles et souvent voyants. The tensioning members used in the prior art are either a peripheral bungee cord passing through eyelets, or mechanical tensioners (threaded rod, turnbuckle, etc.) or springs in tension, via a rigid rod passed in a peripheral sheath integrated to the textile membrane, or a rigid frame pinching the perimeter of the membrane giving it a certain tension, etc. These tensioning members of the prior art have the common characteristic of being bulky, visible and often conspicuous.
DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION
Le préalable à l'utilisation du procédé conforme à l'invention est de disposer d'un cadre rigide sur lequel on désire tendre une membrane textile. Les dimensions des côtés de ce cadre supposé rectangulaire, sans que cela soit limitatif, peuvent aller jusqu à plusieurs mètres. The prerequisite for using the method according to the invention is to have a rigid frame on which it is desired to tension a textile membrane. The dimensions of the sides of this supposedly rectangular frame, without this being limiting, can go up to several meters.
La membrane textile est censée être résistante (plus de 200 daN/5cm en traction axiale à la rupture), peu élastique (module de Young par mètre linéaire supérieur à 30 000 daN/m) et présenter un fluage faible (inférieur à 0.5% de la longueur pour une charge continue égale au dixième de la charge de rupture). The textile membrane is supposed to be resistant (more than 200 daN / 5cm in axial tension at break), not very elastic (Young's modulus per linear meter greater than 30 000 daN / m) and to have a low creep (less than 0.5% of the length for a continuous load equal to one-tenth of the breaking load).
Le tissu de la membrane textile peut être un tissage de polyester enduit de PVC, ou un 30 tissage de fibres de verre enduit de PTFE ou tout autre tissu technique. The fabric of the textile membrane may be a polyester weave coated with PVC, or PTFE coated glass fiber weave or any other technical fabric.
Le pourtour de la membrane textile est équipé d'un fourreau (ourlet) dans lequel on glisse un jonc métallique pouvant être un rondin d'acier sans que cela soit limitatif. Des échancrures sont créées à espacement régulier (entre 30cm et lm suivant le cas) pour pouvoir accrocher les systèmes de tension conformes à l'invention. The periphery of the textile membrane is equipped with a sheath (hem) in which is slipped a metal ring that can be a steel log without this being limiting. Notches are created at regular spacing (between 30cm and 1m as appropriate) to hang the voltage systems according to the invention.
Dans le cas habituel où plusieurs membranes rectangulaires sont placées à la suite, un espacement de l'ordre de quelques centimètres est ménagé entre 2 membranes consécutives pour créer un joint creux visuel. In the usual case where several rectangular membranes are placed in succession, a spacing of the order of a few centimeters is provided between two consecutive membranes to create a visual hollow seal.
Le procédé conforme à l'invention consiste en une boîte à ressorts fixée (à intervalles réguliers) sur le cadre rigide sur lequel on désire tendre la membrane, boîte à ressort se trouvant derrière le plan de la membrane et donc masquée au regard par cette dernière. The method according to the invention consists of a spring box fixed (at regular intervals) on the rigid frame on which it is desired to tension the membrane, spring box located behind the plane of the membrane and thus hidden from view by the latter .
Les ressorts équipant la boîte fonctionnent en torsion, ce qui leur permet d'être placé dans un plan décalé par rapport à celui de la membrane. The springs on the box work in torsion, which allows them to be placed in a plane offset from that of the membrane.
Les ressorts sont généralement au nombre de 2, pour pouvoir tendre 2 membranes consécutives depuis le même joint. Cependant, si la membrane concernée présente un côté de rive (sans membrane consécutive), la boîte à ressort sera équipée d'un seul ressort. The springs are generally 2 in number, to be able to tighten 2 consecutive membranes from the same joint. However, if the membrane concerned has a side edge (without consecutive membrane), the spring box will be equipped with a single spring.
Par ailleurs, la dureté du ressort est réglable par sa position dans la boîte. Moreover, the hardness of the spring is adjustable by its position in the box.
Pour finir, quand la boîte à ressorts est prête à recevoir la membrane textile, les ressorts doivent être armés, c'est-à-dire que l'extrémité du ressort crochetant le jonc métallique de la membrane est bloquée dans un ergot ménagé sur la boîte à ressorts. Finally, when the spring box is ready to receive the textile membrane, the springs must be armed, that is to say that the end of the spring hooking the metal ring of the membrane is locked in a lug formed on the spring box.
Donc, les boîtes à ressorts sont fixées au cadre à intervalles réguliers, centrées sur les joints entre panneaux, la membrane textile est accrochée par l'intermédiaire de son jonc périphérique aux ressorts armés. On peut alors mettre la membrane en tension en libérant les ressorts dans un ordre pré-établi pour uniformiser les tensions. Thus, the spring boxes are fixed to the frame at regular intervals, centered on the joints between panels, the textile membrane is attached via its peripheral ring to the springs armed. The membrane can then be tensioned by releasing the springs in a pre-established order to standardize the voltages.
La tension appliquée à la membrane dans les 2 directions est de l'ordre de 50 à 200 daN/ml suivant réglage et espacement des ressorts. The voltage applied to the membrane in both directions is of the order of 50 to 200 daN / ml depending on the setting and spacing of the springs.
