Abstract

The wall has a flexible trellis (2) fixed on a tight rope (4) passing through drill holes (5, 6) crossing through circular shaped tubular columns (3). An axis of the drill holes realized in each column is shifted with respect to a vertical median plane (M) of the column to be in a plane (P) closest to the trellis. A support surface of the rope is larger than that of the drill holes along the vertical median plane of the column. The axis of the holes is defined based on diameter of the holes such that the holes are close to tangent at an inner face of the column.

Description

TREILLIS MONTE SUR CABLES TENDUS. L'invention se rapporte à une paroi en treillis fixée sur des câbles tendus. Pour la réalisation de clôtures, de pare ballons ou de main courante notamment dans le domaine sportif etc, il est connu d'utiliser un treillis généralement souple fixé sur des 5 câbles tendus, ce treillis étant souvent appelé grillage à mailles. Il n'est pas suffisant d'accrocher le treillis souple ou grillage uniquement au niveau des poteaux c'est pourquoi on fait appel à des câbles tendus. Ces câbles sont tendus entre deux montants extrêmes et très souvent des poteaux intermédiaires sont utilisés pour soutenir les câbles tendus. Si la distance entre les deux 10 montants extrêmes est trop importante, il faut soutenir régulièrement les câbles par des poteaux. La distance entre deux poteaux est de l'ordre de deux à trois mètres. Le principe de pose est le suivant : On fixe les poteaux dans le sol, on fixe chaque câble sur chaque poteau, on tend les câbles et on fixe le treillis sur les câbles au moyen d'agrafes fermées par exemple avec une pince FR 2447782. Le treillis est donc posé en façade et il est lui-même tendu. Chaque câble doit être associé à chaque poteau pour que ce dernier puisse reprendre les efforts. Les poteaux utilisés sont très souvent tubulaires et ont une section circulaire dans les applications sportives. 20 Pour la liaison du câble aux poteaux, certes la ligature existe mais elle n'est plus très souvent utilisée. On utilise parfois une bride fixée par un rivet traversant la paroi du poteau. Parfois, les poteaux présentent un anneau soudé sur la face externe, cet anneau soudé servant de guide fil. 25, Cela nécessite une opération de soudage qui est consommatrice d'énergie. Il est également connu de percer de part en part le poteau. En raison de la forme circulaire, le perçage est centré dans le plan médian vertical du poteau. Le câble traverse les poteaux et il est tendu. L'ensemble des câbles est alors dans le plan médian vertical de chaque poteau. TRELLIS MOUNTED ON TENSILE CABLES. The invention relates to a lattice wall fixed on tensioned cables. For the realization of fences, balloons or handrails especially in the sports field etc, it is known to use a generally flexible mesh attached to tensioned cables, this mesh is often called mesh mesh. It is not sufficient to hang the flexible mesh or grid only at the posts, so tense cables are used. These cables are stretched between two extreme uprights and very often intermediate poles are used to support the tensioned cables. If the distance between the two extreme uprights is too great, the cables should be regularly supported by poles. The distance between two poles is of the order of two to three meters. The laying principle is as follows: The posts are fixed in the ground, each cable is fixed to each post, the cables are tensioned and the mesh is fixed to the cables by means of closed clips, for example with a clip FR 2447782. The trellis is placed in front and is itself stretched. Each cable must be associated with each pole so that it can resume efforts. The posts used are very often tubular and have a circular section in sports applications. For the connection of the cable to the posts, certainly the ligature exists but it is not very often used. Sometimes used a flange fixed by a rivet through the wall of the post. Sometimes the poles have a welded ring on the outer face, this welded ring serving as a wire guide. 25, This requires a welding operation that consumes energy. It is also known to pierce the pole from one side to the other. Due to the circular shape, the drilling is centered in the vertical median plane of the post. The cable goes through the posts and is stretched. The set of cables is then in the vertical median plane of each post.

On comprend que le treillis étant posé en applique sur les poteaux, il devrait s'étendre dans un plan parallèle au plan défini par les câbles. Mais les anneaux fendus sont de petites tailles (taille inférieure au demi-diamètre du poteau) et de ce fait lorsqu'on accroche le grillage sur les fils, ces anneaux tendent à s rapprocher le treillis du câble. Cela dévie donc le câble et/ou le treillis. On pose de deux à trois agrafes par mètre et la plus proche du poteau est à environ vingt centimètres. Cela a plusieurs conséquences. La première conséquence est qu'en sortie du perçage, le câble est dévié vers le treillis, w il s'appuie alors sur une arête vive. Lorsque ce treillis est frappé par un ballon, il vibre et ces vibrations font travailler le câble comme sur un couteau ce qui limite la durée de vie des câbles. Une autre conséquence est qu'au voisinage du poteau, le câble est suffisamment éloigné du treillis pour servir de zone d'appui pour un pied aidant ainsi une personne à 15 franchir la clôture. Une troisième conséquence est que cela déforme le treillis qui fait des bosses au niveau des poteaux car le câble est plus tendu que le treillis ce qui nuit à l'esthétique. L'invention se rapporte à une paroi formée d'un treillis souple posé en applique sur des poteaux tubulaires de section circulaire, le dit treillis étant fixé sur des câbles 20 tendus traversant des perçages traversant lesdits poteaux, cette paroi étant caractérisée en ce que l'axe du perçage réalisé dans chaque poteau est décalé par rapport au plan médian vertical dudit poteau pour être dans un plan plus proche du treillis. L'invention sera bien comprise à l'aide de la description ci après faite à titre d'exemple non limitatif en regard du dessin qui représente schématiquement : 25 FIG 1A: coupe verticale montrant l'état de la technique. FIG lB : Coupe horizontale montrant l'état de la technique. FIG 2 : Une portion de paroi montée selon l'invention. FIG 3 un détail de la figure 2 agrandi FIG 4 : une coupe verticale de l'invention à comparer avec la figure 1A. 30 FIG 5 : une coupe horizontale de l'invention à comparer avec la figure 1B FIG 6 : Coupe horizontale d'un poteau selon l'invention passant par les percages It is understood that the mesh being laid down on the posts, it should extend in a plane parallel to the plane defined by the cables. But the split rings are small sizes (size less than the half-diameter of the post) and therefore when hanging the wire mesh, these rings tend to get closer to the wire mesh. This deviates therefore the cable and / or the trellis. Two to three staples are placed per meter and the closest to the post is about twenty centimeters. This has several consequences. The first consequence is that at the exit of the bore, the cable is diverted towards the trellis, w he then leans on a sharp edge. When this lattice is struck by a balloon, it vibrates and these vibrations make the cable work as on a knife which limits the life of the cables. Another consequence is that in the vicinity of the post, the cable is sufficiently far from the trellis to serve as a support zone for a foot thus helping a person to cross the fence. A third consequence is that it deforms the lattice which makes bumps at the posts because the cable is tighter than the lattice which is detrimental to the aesthetics. The invention relates to a wall formed of a flexible mesh laid down on tubular posts of circular cross-section, said mesh being fixed on tensioned cables 20 passing through holes through said posts, this wall being characterized in that The axis of the drilling made in each post is offset relative to the vertical median plane of said post to be in a plane closer to the lattice. The invention will be better understood using the following description given by way of non-limiting example with reference to the drawing which shows schematically: FIG 1A: vertical section showing the state of the art. FIG. 1B: Horizontal section showing the state of the art. FIG 2: A wall portion mounted according to the invention. FIG 3 is a detail of FIG. 2 enlarged FIG. 4: a vertical section of the invention to be compared with FIG. 1A. FIG. 5: a horizontal section of the invention to be compared with FIG. 1B FIG. 6: Horizontal section of a pole according to the invention passing through the holes

Les figures lA et 1B montrent l'état de la technique et très précisément la position de l'axe 8 de perçage du poteau et celle du treillis qui est ici un treillis souple à mailles losanges. En se reportant au dessin, on voit une paroi 1 formée d'un treillis 2 souple posé en applique sur des poteaux 3 tubulaires de section circulaire et, le dit treillis est fixé sur des câbles 4 tendus traversant des perçages 5,6 traversant lesdits poteaux. Le treillis 2 est également tendu. La tension dans le treillis est plus faible que celle exercée sur les câbles. Les moyens de mise en tension ne sont pas représentés. FIGS. 1A and 1B show the state of the art and very precisely the position of the piercing axis 8 of the post and that of the trellis which is here a flexible mesh with diamond meshes. Referring to the drawing, there is shown a wall 1 formed of a flexible mesh 2 laid down on tubular posts 3 of circular section and said lattice is fixed on cables 4 stretched through holes 5,6 through said posts . The lattice 2 is also stretched. The tension in the lattice is lower than that exerted on the cables. The tensioning means are not represented.

Des agrafes 7 fermées pour former chacune un anneau fixent le treillis sur les câbles. L'agrafe la plus proche du poteau est environ à vingt centimètres. Pour la suite on considéra que tous les poteaux sont alignés suivant un axe. La figure 1A montre la position des perçages selon l'état de la technique, c'est-à-dire centrée. Staples 7 closed to each form a ring fix the mesh on the cables. The staple closest to the post is about twenty centimeters. For the rest it was considered that all the posts are aligned along an axis. Figure 1A shows the position of the holes according to the state of the art, that is to say centered.

La figure 1B montre en vue de dessus une paroi selon l'état de la technique et on voit clairement la déviation du treillis et l'espace entre le câble et le treillis pouvant servir de point d'appui pour franchir la paroi. Les figures 2 et suivantes montrent l'innovation. Avantageusement, l'axe 8 des perçages , 5,6 réalisés dans chaque poteau est décalé 2C) par rapport au plan médian M vertical dudit poteau pour être dans un plan P plus proche du treillis. De ce fait, on rapproche le plan P du plan Z dans lequel s'étend le treillis avant ancrage sur les câbles. Ainsi, la mise en place des agrafes ne va plus tendre à déplacer autant le treillis vers le 25 câble. Avantageusement, l'axe 8 des perçages est défini en fonction du diamètre du perçage pour que les dits perçages soient très proches de la tangente T à la face intérieure du poteau tubulaire. Il pourra être tangent ( figure 6) ou légèrement écarté ( un à cinq millimètres pour un diamètre de poteau de soixante millimètres). 30 En procédant de la sorte, on diminue fortement le phénomène de cisaillement et le câble vient en appui sur une surface 10 beaucoup plus étendue que si on avait percé Figure 1B shows a top view of a wall according to the state of the art and clearly shows the deviation of the lattice and the space between the cable and the lattice can serve as a fulcrum to cross the wall. Figures 2 and following show the innovation. Advantageously, the axis 8 of the holes, 5.6 made in each post is shifted 2C) relative to the vertical median plane M of said post to be in a plane P closer to the lattice. As a result, the plane P is brought closer to the plane Z in which the mesh extends before anchoring on the cables. Thus, the introduction of the staples will no longer tend to move the lattice towards the cable as much. Advantageously, the axis 8 of the bores is defined according to the diameter of the bore so that said holes are very close to the tangent T to the inner face of the tubular post. It may be tangent (Figure 6) or slightly spaced (one to five millimeters for a post diameter of sixty millimeters). By proceeding in this way, the shearing phenomenon is greatly reduced and the cable bears on a much larger surface than if it had been pierced.

dans le plan médian du poteau. En effet lorsqu'on perce un poteau tubulaire circulaire, le perçage étant centré sur le plan médian vertical, la surface de contact est quasi celle de l'épaisseur de la paroi du poteau par contre lorsqu'on déplace l'axe de perçage vers l'extérieur, on augmente cette surface de contact. Les frottements sont répartis sur une plus grande surface. Cela résulte de la forme circulaire du poteau. Ensuite, du fait que le câble n'est quasiment plus dévié, il y a beaucoup moins d'effet de cisaillement. Le câble étant très proche du treillis, il ne constitue plus, en outre, un point d'appui pour mettre son pied afin de franchir la paroi. Il suffit de comparer la figure 1B et la 10 figure 5. Ce montage s'applique à toute paroi sportive ou non, pare ballon, main courante etc mettant en oeuvre un treillis souple ou grillage à mailles fixé sur des fils tendus traversant des poteaux tubulaires. Pour réaliser ce perçage on peut utiliser les outils traditionnels, mais un laser sera plus 15 approprié. Le trou débouchant des orifices 5, 6 est l'intersection d'un cercle et d'une face courbe, il est de forme elliptique. in the median plane of the post. Indeed when drilling a circular tubular pole, the bore being centered on the vertical median plane, the contact surface is almost that of the wall thickness of the pole against against when moving the drilling axis to the outside, this contact surface is increased. Frictions are spread over a larger area. This results from the circular shape of the post. Then, because the cable is almost no longer deflected, there is much less shearing effect. The cable is very close to the trellis, it is no longer, in addition, a point of support to put his foot to cross the wall. It is sufficient to compare FIG. 1B and FIG. 5. This assembly is applicable to any sporting wall or not, such as a balloon, handrail, etc, using a flexible mesh or mesh to be fixed on tensioned wires passing through tubular poles. . To achieve this drilling, traditional tools can be used, but a laser will be more appropriate. The opening hole of the orifices 5, 6 is the intersection of a circle and a curved face, it is of elliptical shape.
