Description
La présente invention concerne un système de précâblage pour le câblage intérieur de bâtiments. Elle concerne également un procédé de câblage mettant en ceuvre ledit système de précâblage. The present invention relates to a prewiring system for the interior wiring of buildings. It also relates to a wiring method implementing said pre-wiring system.
L'invention trouve une application particulièrement avantageuse dans le domaine du câblage intérieur de bâtiments, notamment par câbles optiques. Le précâblage intérieur d'un bâtiment au moyen de tubes consiste à installer dans infrastructures du bâtiment des tubes préalablement vides, chaque tube étant destiné à recevoir ultérieurement un câble, tel qu'un cable optique, qui posé à l'intérieur du tube en fonction de la demande de câblage. The invention finds a particularly advantageous application in the field of interior wiring of buildings, in particular by optical cables. The interior pre-wiring of a building by means of tubes consists in installing in the building infrastructure previously empty tubes, each tube being intended to subsequently receive a cable, such as an optical cable, which laid inside the tube in function of the wiring request.
Le précablage par tubes apporte une grande flexibilité économique, du fait de l'étalement de l'investissement dans le temps, mais aussi technique car il permet le câblage à la demande, la redistribution des tubes, le changement de câbles, etc. Pre-wiring by tubes provides great economic flexibility, due to the staggering of the investment over time, but also technical because it allows cabling on demand, redistribution of tubes, change of cables, etc.
Pour répondre aux besoins de distribuer les tubes en un meure endroit à l'intérieur d'un bâtiment, il est connu, par exemple, des systèmes de précâblage qui consistent à assembler des tubes, 4 ou 7, en toron gainé diamètre de ou 18 mm. Cet assemblage de tubes en hélice permet de conserver un rayon de courbure relativement faible par rapport au diamètre du toron. L'installation des torons de tubes s'effectue dans les parties communes du bâtiment, comme pour les câbles cuivre ou optiques, à savoir par dévidage des longueurs, découpe et tirage dans les chemins de câbles, puis accrochage. To meet the needs of distributing the tubes in one place inside a building, it is known, for example, pre-wiring systems which consist in assembling tubes, 4 or 7, in sheathed strand diameter of or 18 mm. This assembly of helical tubes makes it possible to maintain a relatively small radius of curvature compared to the diameter of the strand. The installation of the strands of tubes is carried out in the common parts of the building, as for copper or optical cables, namely by unwinding the lengths, cutting and pulling in the cable trays, then hanging.
Toutefois, l'utilisation de tubes assemblés en toron présente quelques inconvénients. En particulier, le pas de l'hélice d'un toron est contraignant quand il s'agit d'utiliser certaines techniques de pose de câbles dans un tube notamment le tirage et le poussage avec ou sans air. D'autre part, l'assemblage en toron n'autorise pas la répartition des tubes d'un même toron en plusieurs sous-répartiteurs d'étages ou entre plusieurs points d'accès car les tubes ne sont pas facilement extractibles unitairement du toron. Or, cette fonction est particulièrement intéressante pour dimensionner au plus juste le nombre de tubes nécessaires, par étage ou par point d'accès, tout en limitant les tirages. However, the use of stranded tubes has some drawbacks. In particular, the pitch of the helix of a strand is restrictive when it comes to using certain techniques for laying cables in a tube, in particular drawing and pushing with or without air. On the other hand, the strand assembly does not allow the distribution of the tubes of the same strand into several sub-distributors of floors or between several access points because the tubes are not easily extractable individually from the strand. However, this function is particularly advantageous for sizing the number of tubes required as precisely as possible, per stage or per access point, while limiting the draws.
Aussi, le problème technique à résoudre par l'objet de la présente invention est de proposer un système de précâblage pour le câblage intérieur de bâtiments, comprenant une pluralité de tubes destinés, chacun, à recevoir un câble de transmission, qui permettrait de remédier aux inconvénients présentés par les systèmes connus par assemblage en toron. Also, the technical problem to be solved by the object of the present invention is to provide a prewiring system for the interior wiring of buildings, comprising a plurality of tubes each intended to receive a transmission cable, which would make it possible to remedy the disadvantages presented by known systems by strand assembly.
La solution au problème technique posé consiste, selon la présente invention, en ce que ledit système est formé d'une nappe planaire de tubes accolés latéralement et aptes à être séparés individuellement uns des autres. Ainsi, le système de précâblage conforme à l'invention permet, par simple séparation et épanouissement des tubes de la nappe, desservir plusieurs points d'accès ou sous-répartiteurs, ce qui ne peut être réalisé facilement avec les systèmes à torons de tubes. Pour cela, la liaison entre les tubes d'une même nappe doit, naturellement, être assez faible pour obtenir séparation manuelle des tubes, immédiate et sans outils, sous l'action d'une force transversale de quelques dizaines à quelques centaines de grammes. De plus, les tubes disposés en nappe ne présentant pas de forme hélice se prêtent bien aux différentes techniques de pose câbles comme le tirage, le portage, le poussage, utilisés seuls ou combinés. The solution to the technical problem posed consists, according to the present invention, in that said system is formed of a planar sheet of tubes joined laterally and able to be separated individually from each other. Thus, the pre-wiring system according to the invention allows, by simple separation and development of the tubes of the sheet, to serve several access points or sub-distributors, which cannot be easily achieved with systems with strands of tubes. For this, the connection between the tubes of the same ply must, of course, be weak enough to obtain manual separation of the tubes, immediate and without tools, under the action of a transverse force of a few tens to a few hundred grams. In addition, the tubes arranged in a sheet not having a helical shape lend themselves well to the various cable laying techniques such as pulling, carrying, pushing, used alone or in combination.
D'autre part, le système de précâblage, objet de l'invention, présente certain nombre d'avantages par rapport aux systèmes connus. peut constater, en effet, que la liaison entre les tubes reste dans les dimensions de la nappe et n'offre donc aucune partie saillante susceptible d'être un point d'accrochage lors du tirage de la nappe dans les chemins de câbles. Par ailleurs, un système à nappe facilement épanouissable permet de résoudre le problème du passage dans des espaces réduits que l'on rencontre notamment dans les immeubles anciens, tels que poutres, traversées ou chemins de câbles encombrés. En effet, les nappes peuvent être défaites pour prendre une configuration proche de celle des passages à franchir. De plus, contrairement aux torons qui ont un diamètre fixe d'une dizaine de millimètres, les nappes de tubes, dissymétriques, présentent une hauteur très faible, 6 à 8mm au maximum, et peuvent se courber aussi facilement qu'un seul tube et prendre des rayons très petits, ce qui arrive fréquemment dans les bâtiments Selon un premier mode de réalisation de l'invention, lesdits tubes sont associés de manière discontinue le long de ladite nappe, tandis qu'un deuxième mode de réalisation prévoit que lesdits tubes sont associés de manière continue le long de ladite nappe. Le premier mode de réalisation est particulièrement avantageux car une association de tubes discontinue, voire ponctuelle, offre une séparation de tubes plus rapide. D'autre les tubes sont propres pour le raccordement et la nappe peut être plus économique à fabriquer. On the other hand, the pre-wiring system, object of the invention, has a number of advantages over known systems. can see, in fact, that the connection between the tubes remains in the dimensions of the sheet and therefore does not offer any projecting part capable of being a point of attachment during the drawing of the sheet in the cable trays. In addition, an easily spreadable tablecloth system makes it possible to solve the problem of passing through reduced spaces that are encountered in particular in old buildings, such as beams, crossings or congested cable trays. Indeed, the layers can be undone to take a configuration close to that of the passages to be crossed. In addition, unlike strands which have a fixed diameter of about ten millimeters, the asymmetrical layers of tubes have a very low height, 6 to 8mm at most, and can bend as easily as a single tube and take very small radii, which frequently occurs in buildings According to a first embodiment of the invention, said tubes are associated in a discontinuous manner along said sheet, while a second embodiment provides that said tubes are associated continuously along said sheet. The first embodiment is particularly advantageous because a discontinuous or even punctual combination of tubes offers faster tube separation. On the other hand, the tubes are clean for connection and the sheet can be more economical to manufacture.
Enfin, un procédé de câblage intérieur d'un bâtiment remarquable en ce comporte les étapes consistant à - installer au moins un système de précâblage selon l'invention, - introduire dans les tubes les câbles de transmission respectifs. Avantageusement, l'étape d'installation du système de précâblage comporte au moins une étape de séparation manuelle d'au moins un des tubes. Finally, a method of interior wiring of a building remarkable in that comprises the steps consisting in - installing at least one pre-wiring system according to the invention, - introducing the respective transmission cables into the tubes. Advantageously, the step of installing the prewiring system comprises at least one step of manual separation of at least one of the tubes.
plus, on peut noter que, les tubes étant alignés côte à côte, l'invention permet de corréler de manière univoque les entrées de tubes de la nappe et les sorties, d'où la possibilité d'indexation des tubes vue de leur repérage et leur rangement le long de leur trajet dans les chemins câbles. more, it may be noted that, the tubes being aligned side by side, the invention makes it possible to correlate unequivocally the tube inlets of the sheet and the outlets, hence the possibility of indexing the tubes in view of their location and their storage along their path in the cable trays.
La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée. The description which follows with reference to the appended drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be implemented.
La figure 1 est une vue en perspective d'un système précâblage conforme à l'invention. La figure 2 est une vue de dessus d'un premier mode réalisation du système de la figure 1. Figure 1 is a perspective view of a prewiring system according to the invention. FIG. 2 is a top view of a first embodiment of the system of FIG. 1.
La figure 3 est une vue de dessus d'un deuxième mode de réalisation du système de la figure 1. Sur la figure 1 est représenté un système de précâblage pour le câblage intérieur de bâtiments, destiné à recevoir, par exemple, quatre câbles optiques 11,12,13,14. Ce système de précâblage est formé d'une nappe planaire 20 de tubes 21,22,23 accolés latéralement, chacun desdits tubes recevant un desdits câbles optiques 11,12,13,14. FIG. 3 is a top view of a second embodiment of the system of FIG. 1. In FIG. 1 is shown a pre-wiring system for the interior wiring of buildings, intended to receive, for example, four optical cables 11 , 12,13,14. This pre-wiring system is formed of a planar layer 20 of tubes 21, 22, 23 joined laterally, each of said tubes receiving one of said optical cables 11, 12, 13, 14.
Comme on peut le voir plus spécialement sur les figures 2 et 3, les tubes 21,22,23,24 sont aptes a être séparés individuellement les uns des autres par rupture manuelle liaison entre deux tubes consécutifs, sans besoin d'utiliser d' outils quelconques. As can be seen more particularly in FIGS. 2 and 3, the tubes 21, 22, 23, 24 are capable of being separated individually from each other by manual breakage connection between two consecutive tubes, without the need for tools any.
Dans le mode de réalisation de la figure 2, la liaison est telle que les tubes 21,22,23,24 sont associes manière continue le long de la nappe 20. La séparation des tubes se fait rupture manuelle des cordons 1,2,3 de liaison entre deux tubes accolés. In the embodiment of FIG. 2, the connection is such that the tubes 21,22,23,24 are associated continuously along the ply 20. The separation of the tubes is done by manual breaking of the cords 1,2,3 of connection between two joined tubes.
Dans le mode de réalisation de la figure 3, la liaison est telle que les tubes 21,22,23,24 sont associes manière discontinue le long de la nappe 20. La séparation des tubes fait par rupture manuelle des points 1',2',3' de liaison entre deux tubes accolés. In the embodiment of FIG. 3, the connection is such that the tubes 21, 22, 23, 24 are combined discontinuously along the ply 20. The separation of the tubes is done by manual breaking of the points 1 ', 2' , 3 'of connection between two joined tubes.
D'une manière générale, les tubes 21,22,23,24 sont réalisés en un matériau plastique souple cintrable comme un polyimide, le polypropylène, le polyéthylène, etc, tandis que les cordons 1,2,3 ou points 1',2',3' de liaison sont réalisés dans une colle de faible adhérence, la nappe 20 de tubes étant obtenue par collage ou soudage de tubes ou par coextrusion. In general, the tubes 21, 22, 23, 24 are made of a flexible, bendable plastic material such as a polyimide, polypropylene, polyethylene, etc., while the cords 1,2,3 or points 1 ′, 2 ', 3' of bonding are made in a glue of low adhesion, the sheet 20 of tubes being obtained by gluing or welding of tubes or by coextrusion.
