La presente invención se refiere a un conducto para fluidos, siendo dicho conducto del tipo de los que presentan una configuración tubular definida por una pared exterior de sección anular o poligonal que delimita un hueco o pasaje interior para la circulación de dichos fluidos. El conducto para fluidos de la presente invención se refiere a cualquier conducto de fluidos, tanto líquidos como por ejemplo a gua, como gases, como por ejemplo aire con o sin humos o gases de combustión, y por tanto comprende tanto elementos de los llamados tuberías, como chimeneas, o simplemente conductos para fluidos.The present invention relates to a conduit for fluids, said conduit being the type of those presenting a tubular configuration defined by an outer wall of annular or polygonal section that delimits an internal hole or passage for the circulation of said fluids. The fluid conduit of The present invention relates to any fluid conduit, both liquids such as gua, such as gases, such as air with or without fumes or flue gases, and therefore includes both elements of the so-called pipes, as chimneys, or Simply fluid conduits.

Antecedentes de la invenciónBackground of the invention

Actualmente son ampliamente conocidas los conductos tubulares para fluidos, que pueden presentar secciones de cualquier forma geométrica, aunque las más utilizadas son las de sección circular y los de sección rectangular.Currently, the tubular fluid conduits, which may have sections of any geometric shape, although the most used are those of circular section and those of rectangular section.

La sección de estos conductos se encuentra definida por una pared exterior de un material como por ejemplo poli(cloruro de vinilo), polietileno, polipropileno, u otros similares.The section of these ducts is located defined by an outer wall of a material such as poly (vinyl chloride), polyethylene, polypropylene, or others Similar.

Generalmente estos conductos se obtienen por extrusión y una vez conformados presentan una cierta consistencia, lo que impide una deformación excesiva de los mismos sin provocar su rotura.Generally these ducts are obtained by extrusion and once formed they have a certain consistency, which prevents excessive deformation thereof without causing its breakage

Estas características de los conductos empleados habitualmente plantea diversos problemas siendo el principal la gran cantidad de espacio necesario para su almacenaje y transporte, ya que la configuración tubular de dichos conductos impide el aprovechamiento del espacio interior de los mismos durante las mencionadas operaciones de almacenaje y transporte.These characteristics of the ducts used It usually raises various problems, the main one being large amount of space needed for storage and transportation, since the tubular configuration of said ducts prevents use of their interior space during mentioned storage and transport operations.

Otro de los problemas que plantea la rigidez o elevada consistencia de algunos de estos conductos es que no se puede realizar su instalación en aquellas zonas de paso que definen un hueco de altura menor a la del conducto, aunque dicha diferencia dimensional sea muy pequeña. Esta circunstancia obliga a que en el mercado sea necesaria una gran variedad de conductos con alturas diferentes, lo que conduce a la necesidad de mayores almacenes y mayores inversiones en el material almacenado.Another problem posed by stiffness or high consistency of some of these ducts is that it is not You can install in those areas that define a gap of smaller height than the duct, although said difference Dimensional be very small. This circumstance forces that in the market is necessary a wide variety of ducts with heights different, which leads to the need for larger stores and greater investments in stored material.

Descripción de la invenciónDescription of the invention

Este conducto presenta unas particularidades constructivas orientadas a permitir una deformación elástica de la sección del conducto para proporcionarle eventualmente una configuración aplanada, lo que permite que un tubo de una única altura se pueda instalar en zonas de paso de alturas inferiores, así como permite igualmente su configuración totalmente aplanada para reducir de forma considerable el espacio necesario para su almacenaje y transporte, pues la posterior recuperación elástica de la sección del conducto lo restaura a las dimensiones originales de extrusión, sin pérdida de sus condiciones estancas, y lo deja listo para su instalación incluso en zonas de paso de menor altura.This duct has some peculiarities construction oriented to allow an elastic deformation of the duct section to eventually provide a flattened configuration, allowing a single tube height can be installed in passage areas of lower heights, as well as also allows its fully flattened configuration to considerably reduce the space needed for your storage and transport, because the subsequent elastic recovery of the duct section restores it to the original dimensions of extrusion, without losing its watertight conditions, and leaves it ready for installation even in lower passage areas.

De acuerdo con la invención, la pared exterior del conducto comprende una porciones longitudinales, continuas, de un material extruible, relacionadas entre sí por unas porciones intermedias, también continuas, que definen unas líneas longitudinales de plegado destinadas a permitir mediante deformación elástica el aplastamiento lateral del conducto para proporcionarle una configuración tubular aplanada y la posterior recuperación de la configuración inicial.According to the invention, the outer wall of the duct comprises a longitudinal, continuous portions of an extrudable material, related to each other by a few portions intermediate, also continuous, which define lines longitudinal folding intended to allow by deformation elastic side duct crush to provide a flattened tubular configuration and subsequent recovery of Initial setup

Para ello, se ha previsto que las porciones longitudinales y las porciones intermedias puedan estar conformadas en materiales de elasticidad adecuada, conformando las porciones de más fácil deformabilidad elástica las líneas longitudinales de plegado, o bien que las porciones longitudinales y las porciones intermedias puedan estar conformadas en un mismo material, presentando en este caso las porciones intermedias un espesor menor, para conformar dichas porciones intermedias las líneas longitudinales de plegado del conducto.For this, it is planned that the portions longitudinal and intermediate portions may be shaped in materials of adequate elasticity, forming the portions of easier elastic deformability the longitudinal lines of folded, or that the longitudinal portions and the portions Intermediates may be formed in the same material, presenting in this case the intermediate portions a thickness minor, to form said intermediate portions the lines Longitudinal folding of the duct.

En el caso de que las porciones longitudinales y las porciones intermedias estén conformadas en distintos materiales se ha previsto que las porciones longitudinales, de mayor resistencia a la deformación, sean de un material de menor elasticidad y que las porciones intermedias sean de un material de mayor elasticidad. En este caso las porciones longitudinales y las porciones intermedias estarán conformadas simultáneamente por coextrusión, lo que permite la fabricación del conjunto a unos costes sensiblemente iguales a los de los conductos convencionales.In the case that the longitudinal portions and the intermediate portions are formed in different materials it is planned that the longitudinal portions, of greater deformation resistance, be of a lower material elasticity and that the intermediate portions be of a material of greater elasticity In this case the longitudinal portions and the intermediate portions will be conformed simultaneously by coextrusion, which allows the manufacturing of the set about costs substantially equal to those of the ducts conventional.

Asimismo y tal como se mencionaba anteriormente, las porciones longitudinales y las porciones intermedias pueden estar conformadas en un mismo material elástico, presentando las porciones intermedias un espesor menor que las porciones longitudinales, a fin de que proporcionen una mayor deformabilidad elástica, conformándose en este caso el conducto mediante la extrusión de un único material.Likewise and as mentioned above, the longitudinal portions and the intermediate portions may be shaped in the same elastic material, presenting the intermediate portions a thickness smaller than the portions longitudinal, so that they provide greater deformability elastic, conforming in this case the conduit through the Extrusion of a single material.
