ÚTIL PARA LA UNIÓN DE COQUILLAS USEFUL FOR THE UNION OF SHELLS
MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un útil para la unión de coquillas que aporta, a la función a que se destina, ventajas y características, que se describen en detalle más adelante y que suponen una mejora del estado actual de la técnica. The invention, as expressed in the title of this specification, refers to a tool for joining shells that provides, to the function for which it is intended, advantages and characteristics, which are described in detail below and which represent a improvement of the current state of the art.
El objeto de la presente invención recae en un útil que, comprendiendo al menos un elemento de unión adhesivo en forma de disco con zonas adhesivas en, al menos, ambos lados del mismo, está diseñado para colocarse entre las coquillas de una tubería a unir con la finalidad de facilitar la fijación de, al menos, los extremos de las mismas entre sí. Además, en una forma de realización preferida, el útil comprende también una herramienta específica de posicionado que facilita la colocación del elemento de unión en una primera coquilla. The object of the present invention lies in a tool that, comprising at least one disc-shaped adhesive joint element with adhesive areas on at least both sides of it, is designed to be placed between the shells of a pipe to be joined with the purpose of facilitating the fixing of, at least, the ends thereof to each other. In addition, in a preferred embodiment, the tool also comprises a specific positioning tool that facilitates the placement of the joining element in a first shell.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de útiles y herramientas de fontanería. The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of plumbing fixtures and tools.
ANTECEDENTES DE LA INVENCIÓN Como es sabido, las coquillas están constituidas por un tubo fabricado con un material aislante térmico, normalmente una espuma elastomérica, que es un tipo de caucho, que usa para recubrir las tuberías de conducción de fluidos, tanto fríos como calientes, para aislarlos y ahorrar energía, por ejemplo en una instalación de calefacción, de climatización o de agua caliente. BACKGROUND OF THE INVENTION As is known, the shells are made up of a tube made of a thermal insulating material, normally an elastomeric foam, which is a type of rubber, which is used to cover the pipes for conducting fluids, both hot and cold, to insulate them and save energy. energy, for example in a heating, air conditioning or hot water installation.
Cuando las tuberías son más largas que las coquillas, cosa que suele ser lo habitual, éstas se van uniendo por sus extremos entre sí y a las tuberías para evitar desplazamientos indeseados de las mismas por efecto de los cambios de temperatura. When the pipes are longer than the shells, which is usually the case, they are joined at their ends to each other and to the pipes to prevent unwanted displacement of them due to temperature changes.
Actualmente el método de pegado de las coquillas se realiza mediante la aplicación de una cola con pincel en ambos lados de las coquillas, después se debe esperar unos minutos, ya que la cola se debe secar antes de pegar. Una vez está seca, se deben juntar y aplicar un pequeña presión. Esta cola también se aplica al tubo, uniendo así ambas coquillas con el tubo, para que la junta no se desplace debido a los cambios de temperatura. Currently the method of gluing the shells is done by applying a glue with a brush on both sides of the shells, then you must wait a few minutes, since the glue must dry before gluing. Once it is dry, they should be put together and apply a little pressure. This glue is also applied to the tube, thus joining both shells to the tube, so that the joint does not move due to temperature changes.
El objetivo de la presente invención es, pues, proporcionar al mercado un sistema mejorado, más rápido y sencillo, para procurar dicha fijación de las coquillas entre sí y, eventualmente, a las tuberías. The objective of the present invention is, therefore, to provide the market with an improved, faster and simpler system to ensure said fixing of the shells to each other and, eventually, to the pipes.
