Description

Dispositivo de sellado ignífugo de una tubería de plástico en su paso a través de una pared.Flame retardant sealing device of a pipe of plastic as it passes through a wall.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un dispositivo de sellado, que ha sido especialmente concebido para mantener sustancialmente la barrera ignífuga definida por una pared, en aquellos puntos en los que dicha pared debe ser atravesada por una tubería de plástico, por ejemplo una tubería de PVC. El dispositivo es igualmente aplicable cuando la tubería de plástico atraviesa un forjado.The present invention relates to a sealing device, which has been specially designed to substantially maintain the flame retardant barrier defined by a wall, at those points where said wall must be crossed by a plastic pipe, for example a pipe of PVC The device is equally applicable when the pipeline plastic goes through a floor.

El objeto de la invención es conseguir un sustancial abaratamiento de costos en la fabricación del dispositivo, por cuanto que el mismo es adaptable a cualquier diámetro de tubería.The object of the invention is to achieve a substantial cost reduction in the manufacturing of device, because it is adaptable to any pipe diameter

Antecedentes de la invenciónBackground of the invention

Habitualmente, cuando se pretende proteger un recinto contra el fuego, además de utilizar materiales apropiados en la construcción de sus paredes y forjados, se utilizan puertas ignífugas, consiguiéndose una barrera al fuego, al menos desde el punto de vista teórico, que impide la propagación del mismo.Usually, when it is intended to protect a fire enclosure, in addition to using appropriate materials in the construction of its walls and floors, doors are used flame retardant, getting a fire barrier, at least from the theoretical point of view, which prevents its propagation.

Sin embargo, en muchas ocasiones dichos muros o forjados deben ser atravesadas por tuberías de plástico, que por su propia naturaleza sí que son combustibles, de manera que dichas tuberías pueden en principio constituir medios de propagación del fuego de un habitáculo al contiguo.However, on many occasions these walls or Forged must be crossed by plastic pipes, which by their nature itself are combustible, so that these pipes can in principle constitute means of propagation of the fire from a cabin next door.

Para solventar este problema es conocida la utilización de collarines y de un material ignífugo, que a modo de casquillos cubren un tramo apropiado a la tubería de plástico, a uno y otro lado de la pared o cerramiento a proteger.To solve this problem, the use of collars and a flame retardant material, which by way of bushings cover a section appropriate to the plastic pipe, to either side of the wall or enclosure to protect.

Esta solución, aunque básicamente válida desde el punto de vista funcional, presenta en la práctica un problema de costos, ya que es preciso fabricar un collarín especifico para cada diámetro de tubería de plástico, lo que no solo genera problemas de fabricación, como anteriormente se ha dicho, sino también de estocaje y de disponibilidad en el momento de efectuar el montaje "in situ".This solution, although basically valid from the functional point of view, presents in practice a cost problem, since it is necessary to manufacture a specific collar for each diameter of plastic pipe, which not only generates manufacturing problems, as previously He said, but also of stock and availability at the time of mounting " on site ".

Un problema añadido consiste en que estos collarines de sellado deben ser montados en el mismo momento en el que se realiza la instalación de la tubería, para permitir que ésta pase a su través, lo que hace prácticamente imposible sellar una instalación "vieja", es decir una instalación que se encuentre ya en situación de uso.An added problem is that these sealing collars must be mounted at the same time in the that the pipe installation is done, to allow it pass through it, which makes it virtually impossible to seal a "old" installation, that is to say an installation found already in use situation.

La citada chapa de acero (2) está afectada por una pluralidad de líneas de precorte o de debilitamiento transversales (3) que definen en la misma una alineación de módulos (4), como se observa especialmente en la figura 1, independizables en número variable de resto de la base (2) para conseguir una longitud efectiva del dispositivo acorde con el perímetro de la tubería (5) a la que se destina.The aforementioned steel plate (2) is affected by a plurality of precut or weakening lines transversal (3) that define in it an alignment of modules (4), as seen especially in Figure 1, independent in variable number of rest of the base (2) to get a effective length of the device according to the perimeter of the pipe (5) to which it is intended.

Así pues el dispositivo de sellado constituye un elemento lineal que, tras su fragmentación se convierte en un anillo que se cierra sobre el perímetro de la tubería a la que se destina, por simple deformación.Thus the sealing device constitutes a linear element that, after fragmentation becomes a ring that closes over the perimeter of the pipe to which it destin, by simple deformation.

La base metálica (2) está provista además de una pluralidad de parejas de aletas (6), laterales, acodadas ortogonalmente hacia dentro, es decir hacia la tira intumescente (1), que afectan lateralmente a los módulos (4), aletas que en el ejemplo de realización práctica elegido adoptan una configuración trapecial isoscélica, de vértices libres redondeados, pero que pueden adoptar cualquier otra configuración.The metal base (2) is also provided with a plurality of pairs of fins (6), lateral, angled orthogonally inwards, that is, towards the intumescent strip (1), which affect the modules laterally (4), fins that in the example of practical implementation chosen adopt a configuration isoscelic trapecial, rounded free vertices, but that They can adopt any other configuration.

Complementariamente todos y cada uno de los módulos (4) de la base de acero (2) están afectados por respectivos troquelados/embuticiones determinantes de protuberancias (7), de perfil trapecial isoscélico, abiertas por sus extremos, que rigidizan los respectivos extremos del perfil o base de acero.Complementarily each and every one of the modules (4) of the steel base (2) are affected by respective punching / drawing of protuberances (7), of isoscelic trapezoidal profile, open at its ends, which stiffen the respective ends of the steel profile or base.

Una vez que ha sido fraccionado del cuerpo alargado y de longitud indefinida el número de módulos (4) adecuados al diámetro de la tubería (5), y una vez que dicha agrupación de módulos ha sido adaptada a la mencionada tubería, para la definitiva fijación de éste collarín, se ha previsto la utilización de horquillas de fijación (8), como mínimo en número de dos y preferentemente en número de cuatro, contando estas horquillas de fijación con una patilla (9) en sus extremos, acodada ortogonalmente hacia dentro, destinada a retener axialmente el collarín contra la pared (10), y en su otro extremo, el correspondiente con dicha pared, una segunda patilla (11), en este caso acodada ortogonalmente hacia fuera, dotada de un orificio para paso del correspondiente tornillo o tirafondo (12) de fijación a la pared (10), con la colaboración de un taco previamente implantado en esta última.Once it has been fractionated from the body elongated and of indefinite length the number of modules (4) appropriate to the diameter of the pipe (5), and once said module grouping has been adapted to the mentioned pipe, for the definitive fixing of this collar, the use of fixing forks (8), at least in number of two and preferably in number of four, counting these fixing forks with a pin (9) at its ends, angled orthogonally inward, intended to axially retain the collar against the wall (10), and at its other end, the corresponding with said wall, a second pin (11), in this case orthogonally angled out, provided with a hole for passage of the corresponding screw or bolt (12) fixing to the wall (10), with the collaboration of a previously implanted block In this last.

Se consigue de esta manera una fijación simple y estable del collarín simultáneamente a la tubería (5) y a la pared (10), que puede realizarse en cualquier momento que se estime oportuno dada la naturaleza abierta del repetidamente citado collarín.In this way a simple fixation is achieved and stable of the collar simultaneously to the pipe (5) and to the wall (10), which can be done at any time it is estimated timely given the open nature of the repeatedly cited collar.
