Junta centradora, uso y conducto aislado que la portaCentering gasket, use and insulated conduit that carries it

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a una junta centradora para conductos de ventilación con tubos concéntricos, que permite fijar su posición relativa y asiste en la unión con los tramos adyacentes. También se refiere a su uso y al conducto aislado que la porta.The present invention refers to a centering gasket for ventilation ducts with concentric tubes, which allows to fix its relative position and assists in the connection with the adjacent sections. It also refers to its use and the isolated conduit that carries it.

Es de aplicación en el campo de las instalaciones para comercios, garajes, cualquier tipo de edificio, buques, etc.It is applicable in the field of facilities for shops, garages, any type of building, ships, etc.

ESTADO DE LA TÉCNICASTATE OF THE ART

En las instalaciones que así lo requieran, los sistemas de conductos circulares que vehiculan aire climatizado, o extracción de humos en los que se tiene que evitar la condensación, llevan incorporado un aislamiento exterior que a su vez necesita estar protegido, ya sea por motivos de acabado o de requerimiento de montaje en exterior. Por ello se ejecutan los conductos metálicos dobles con aislamiento intermedio.In installations that require it, the circular duct systems that carry heated air, or the extraction of fumes in which condensation must be avoided, incorporate an external insulation that in turn needs to be protected, either for reasons of finish or outdoor mounting requirement. This is why double metal conduits with intermediate insulation are executed.

Estos conductos dobles están formados por dos tubos, de forma generalmente circular, concéntricos, y separados por una capa de material aislante flotante.These double conduits are formed by two tubes, generally circular in shape, concentric, and separated by a layer of floating insulating material.

Estos conductos aislados son pesados y la propia gravedad hace que el conducto interior se desplace hacia abajo, oprimiendo la capa de material aislante y extendiendo la parte superior de esa capa. Por lo tanto, se suele colocar una chapa separadora entre ambos, a la que se encuentran soldados los marcos de los dos tubos.These insulated conduits are heavy and gravity itself causes the inner conduit to slide downward, squeezing the layer of insulating material and extending the top of that layer. Therefore, a separating plate is usually placed between the two, to which the frames of the two tubes are welded.

Esta chapa genera, sin embargo, un gran problema de puente térmico, al comunicar mediante un conductor térmico los dos tubos, saltando el material aislante.This sheet generates, however, a great problem of thermal bridge, when communicating by means of a thermal conductor the two tubes, skipping the insulating material.

Este tipo de conductos se realizan en tramos, que generalmente se unen entre sí mediante tiras en "V” invertida que unen los marcos exteriores, comprimiendo un elemento elástico que sella la unión. Para ello, los tubos exteriores tienen un marco ransversa que es pnza o por as ras. e pue e aprecar un eempo e esa un n en WO2006035079A1.This type of ducts are made in sections, which are generally joined together by inverted "V" strips that join the outer frames, compressing an elastic element that seals the joint. For this, the outer tubes have a frame Transverse that it is pnza or as ras. You can check a time that is in WO2006035079A1.

El solicitante no conoce ningún sistema equivalente a la invención.The applicant is not aware of any system equivalent to the invention.

BREVE EXPLICACIÓN DE LA INVENCIÓNBRIEF EXPLANATION OF THE INVENTION

La invención consiste en una junta centradora para conductos de ventilación de tubos concéntricos, según las reivindicaciones. También consiste en el uso de la junta centradora, y en el conducto aislado que la porta.The invention consists of a centering gasket for concentric tube ventilation ducts, according to the claims. It also consists of the use of the centering gasket, and the insulated duct that carries it.

Esta invención permite solventar toda una serie de problemas, como los enumerados:This invention allows solving a whole series of problems, such as those listed:

1. Solventar el problema del "puente térmico” entre el tubo interior y el tubo exterior.1. Solve the problem of the "thermal bridge" between the inner tube and the outer tube.

2. Ser un medio de sujeción y centrado de los dos tubos concéntricos, manteniendo flotante el tubo interior respecto del exterior.2. Be a means of holding and centering the two concentric tubes, keeping the inner tube floating with respect to the outside.

3. Facilitar la estanqueidad con el tramo de conducto adyacente, al permitir el apoyo de la junta de un tramo con la junta del tramo adyacente. El método utilizado para unir los tramos presionará una junta contra la otra.3. Facilitate the sealing with the adjacent duct section, by allowing the support of the joint of a section with the joint of the adjacent section. The method used to join the sections will press one joint against the other.

La junta centradora de la invención está prevista para la unión entre dos tubos concéntricos de un conducto aislado, teniendo el tubo interior un marco interior (orientado hacia el exterior). Posee una sección en "T” con una parte longitudinal y una parte cruzada, y un estrangulamiento en un costado de la unión entre ambas partes.The centering seal of the invention is provided for the connection between two concentric tubes of an isolated conduit, the inner tube having an inner frame (facing outwards). It has a "T" section with a longitudinal part and a crossed part, and a choke on one side of the joint between both parts.

En una realización preferida, también posee unos dientes de sierra en la cara de la parte longitudinal opuesta al estrangulamiento.In a preferred embodiment, it also has saw teeth on the face of the longitudinal part opposite to the throttle.

En otra realización, la parte cruzada posee una cara exterior curvada.In another embodiment, the cross part has a curved outer face.

La invención también se refiere al uso de la junta centradora para mantener la separación entre los tubos de un conducto aislado formado por dos tubos concéntricos, de los cuales el tubo interior tiene un marco interior orientado hacia el exterior del tubo interior. No es relevante para este uso si el tubo exterior también posee su propio marco, pero es la solución más habitual y preferida. The invention also relates to the use of the centering gasket to maintain the separation between the tubes of an insulated duct formed by two concentric tubes, of which the inner tube has an inner frame oriented towards the outside of the inner tube. It is not relevant for this use if the outer tube also has its own frame, but it is the most common and preferred solution.

MODOS DE REALIZACIÓN DE LA INVENCIÓNMODES OF CARRYING OUT THE INVENTION

A continuación se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta.An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.

En la figura 1 se aprecia un primer ejemplo de realización, aplicado a un conducto que posee un tubo interior (1), un tubo exterior (2), concéntrico, y una capa de material aislante (3) intermedia.Figure 1 shows a first example of embodiment, applied to a duct that has an inner tube (1), an outer tube (2), concentric, and an intermediate layer of insulating material (3).

Se aprecia que los tubos (1,2) poseen sendos marcos (11,21) que dan rigidez a la unión y que están preparados para permitir la fijación al tramo de conducto adyacente. Por ese espacio se accede al material aislante (3), que suele estar un poco retirado para facilitar la manipulación y fijación de los tubos (1,2).It can be seen that the tubes (1,2) have respective frames (11,21) that give rigidity to the joint and that are prepared to allow fixing to the adjacent duct section. Through this space you can access the insulating material (3), which is usually slightly removed to facilitate handling and fixing the tubes (1,2).

Como se ha señalado, durante su manipulación, el tubo interior (1) tiende a aplastar la parte inferior del material aislante (3) y a extender la parte superior. Para evitarlo, se u za a una cenra ora e a nvenc n, que se repro uce en m s ea e en a figura 2.As noted, during handling, the inner tube (1) tends to crush the bottom of the insulating material (3) and extend the top. To avoid this, uza a dinra ora ea nvenc n, which is reproduced in ms ea e in figure 2.

Según se aprecia especialmente en la figura 2, que representa un pequeño trozo de junta centradora (4), ésta posee una sección en "T”, con una parte longitudinal (41), preferiblemente con forma de flecha para facilitar la introducción, y una parte cruzada (42) que hace de tope en la introducción. Esa parte cruzada (42) sirve a su vez para apoyarse en la junta centradora (4) del tramo adyacente y asegurar la estanqueidad de la unión. Para mejorar este apoyo, la parte cruzada (42)As especially seen in Figure 2, which represents a small piece of centering gasket (4), it has a "T" section, with a longitudinal part (41), preferably arrow-shaped to facilitate insertion, and a The cross part (42) that acts as a stop in the introduction This cross part (42) serves in turn to rest on the centering joint (4) of the adjacent section and to ensure the tightness of the joint. crossed (42)

Se prefiere colocar unos dientes (43) de sierra en una de las caras de la parte longitudinal (41) para mejorar su fijación e incrementar el tope de anclaje (figura 2). Esos dientes (43) estarán, en posición de uso, orientados hacia el tubo exterior (2).It is preferred to place saw teeth (43) on one of the faces of the longitudinal part (41) to improve its fixation and increase the anchoring stop (Figure 2). Those teeth (43) will be, in use position, oriented towards the outer tube (2).

En la unión entre la parte longitudinal (41) y la parte cruzada (42) se sitúa un estrangulamiento (44), cuya función es visible en la figura 1, es decir, servir de punto de anclaje sobre el marco interior (11), del tubo interior (1). Por lo tanto, estará orientado (en uso) hacia éste.At the junction between the longitudinal part (41) and the crossed part (42) there is a throttle (44), the function of which is visible in figure 1, that is, serving as an anchor point on the inner frame (11), of the inner tube (1). Therefore, it will be oriented (in use) towards it.

La junta centradora (4) tendrá una forma general correspondiente a las medidas del espacio entre los tubos (1,2), para que la colocación sea más sencilla. Sin embargo, es también posible presentar la junta centradora (4) como un material en rollo que se coloca y corta en el momento de aplicación. Este rollo se comercializaría en varias anchuras para corresponder a los huecos disponibles. Este sistema es menos preferido, porque ofrece menor resistencia, pero a cambio reduce el stock y abarata costes de fabricación.The centering seal (4) will have a general shape corresponding to the measurements of the space between the tubes (1,2), to make placement easier. However, it is also possible to present the centering seal (4) as a roll material that is placed and cut at the time of application. This roll would be marketed in various widths to correspond to the available gaps. This system is less preferred, because it offers less resistance, but in return reduces the stock and reduces manufacturing costs.

El material de la junta centradora (4) será elástico, pero no demasiado blando. Por ejemplo, se puede utilizar caucho u otro tipo de goma. The material of the centering seal (4) will be elastic, but not too soft. For example, you can use rubber or another type of rubber.
