PIEZA DE ENTRONQUE PARA ESTRUCTURAS DE BARRAS OBJETO DE LA INVENCIÓN TUNING PIECE FOR BAR STRUCTURES OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una pieza de entronque para estructuras de barras, la cual aporta varias ventajas e innovadoras características inherentes a su particular constitución y configuración, que se describirán con detalle más adelante y que suponen una destacable novedad en el estado actual de la técnica. The invention, as expressed in the statement of the present specification, refers to a connecting piece for bar structures, which provides several advantages and innovative characteristics inherent to its particular constitution and configuration, which will be described in detail below and which represent a remarkable novelty in the current state of the art.
Concretamente, la presente invención consiste en una pieza de entronque, del tipo que posee como finalidad posibilitar la unión entre los extremos de dos barras, de una estructura con distintos ángulos, la cual, es aplicable en particular para estructuras de barras consistentes en perfiles extrusionados, presenta la innovadora particularidad de estar estructuralmente configurada para posibilitar que pueda consistir también en una pieza obtenida por extrusión, lo cual aporta notables ventajas a su función, especialmente en cuanto a resistencia y menor coste de fabricación. Specifically, the present invention consists of a junction piece, of the type whose purpose is to enable the connection between the ends of two bars, of a structure with different angles, which, in particular, is applicable for bar structures consisting of extruded profiles. , presents the innovative feature of being structurally configured to enable it to also consist of a piece obtained by extrusion, which brings significant advantages to its function, especially in terms of strength and lower manufacturing cost.
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 construcción, centrándose particularmente en el ámbito de la construcción de estructuras conformada a base de barras, preferentemente metálicas, pero sin que ello suponga una limitación. ANTECEDENTES DE LA INVENCIÓN The scope of the present invention is framed within the construction sector, focusing particularly on the field of construction of bar-shaped structures, preferably metal, but without limitation. BACKGROUND OF THE INVENTION
Actualmente, la mayoría de estructuras construidas a base de barras, especialmente estructuras metálicas conformadas por barras consistentes en perfiles que se obtienen por extrusión, cuentan para las uniones en distintos ángulos de los extremos de dichas barras con piezas o elementos de entronque que están realizados o bien por fundición en molde o bien a partir de piezas soldadas entre sí para conseguir la configuración concreta de la pieza que permita la citada unión de manera eficiente. Currently, the majority of structures built on bars, especially metal structures made up of bars consisting of profiles that are obtained by extrusion, count for the joints at different angles of the ends of said bars with pieces or elements of junction that are made or either by casting in mold or from pieces welded together to achieve the specific configuration of the piece that allows the said union efficiently.
Esto hace que el material utilizado para las barras o vigas no siempre pueda ser el mismo que el que se utiliza para los entronques por ejemplo si las barras son perfiles de aluminio y, consecuentemente, se pueden llegar a producir desajustes indeseados en la estructura debidos al diferente comportamiento de los materiales ante los cambios de temperatura, esfuerzos u otras circunstancias. Además, si el material es distinto tampoco presenta la misma apariencia. This means that the material used for the bars or beams may not always be the same as that used for the entrances, for example if the bars are aluminum profiles and, consequently, undesired mismatches in the structure due to the structure can occur. different behavior of the materials before the changes of temperature, efforts or other circumstances. In addition, if the material is different, it also does not have the same appearance.
Como referencia al estado actual de la técnica, cabe señalar que se desconoce la existencia de ninguna otra pieza de entronque o invención de aplicación similar que presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta la que aquí se reivindica. As a reference to the current state of the art, it should be noted that the existence of any other piece of junction or invention of similar application that has similar technical, structural and constituent characteristics to those presented here is claimed.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
Así, la pieza de entronque para estructuras de barras que la invención propone, se configura como una destacable novedad dentro de su campo de aplicación, ya que a tenor de su implementación se alcanzan satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo hacen posible y que lo distinguen, convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva. Thus, the piece of junction for bar structures that the invention proposes, is configured as a remarkable novelty within its field of application, since according to its implementation they are achieved satisfactorily the aforementioned objectives, the characterizing details that make it possible and distinguish it, conveniently included in the final claims accompanying the present specification.
Lo que la invención propone es, como ya se ha apuntado anteriormente, una pieza de entronque, aplicable en particular para la unión de dos barras consistentes en perfiles extrusionados, por ejemplo de aluminio, la cual de manera innovadora y ventajosa consiste también en una pieza obtenida por extrusión que presenta unas zonas mecanizadas para ajustarse al perfil de las barras y determinar la inclinación de la unión, permitiendo que pueda estar constituida exactamente del mismo material que los citados perfiles, es decir, por ejemplo de aluminio si los perfiles a unir son del mismo material. What the invention proposes is, as already noted above, a connecting piece, applicable in particular for the joining of two bars consisting of extruded profiles, for example aluminum, which in an innovative and advantageous manner also consists of a piece obtained by extrusion that has machined areas to fit the profile of the bars and determine the inclination of the joint, allowing it to be constituted exactly of the same material as the aforementioned profiles, that is, for example aluminum if the profiles to be joined are of the same material.
Para ello, la pieza de entronque en cuestión se configura a partir de un nuevo perfil extrusionado de menor dimensión y escasa longitud que comprende un esqueleto de configuración apta para encajar dentro de la cavidad interior que presentan los perfiles de las barras a unir, existiendo externamente a dicho esqueleto unas aletas longitudinales susceptibles de ser mecanizadas para otorgarles una determinada inclinación creciente o decreciente, y que normalmente será simétrica, hacia ambos extremos de la pieza, inclinación que irá en función del ángulo que se desee conseguir en el punto de unión entre los dos perfiles. To do this, the piece of junction in question is configured from a new extruded profile of smaller dimension and short length comprising a skeleton of configuration suitable to fit inside the inner cavity that present the profiles of the bars to be joined, existing externally to said skeleton longitudinal fins capable of being machined to give them a certain increasing or decreasing inclination, and which will normally be symmetrical, towards both ends of the piece, inclination that will be a function of the angle that is desired to be achieved at the point of union between the two profiles
Con ello, la pieza de entronque se introduce por ambos lados en los respectivos extremos de los perfiles y la inclinación de los mismos queda determinada por el mecanizado que se haya practicado a las aletas de esta pieza, las cuales estarán preferentemente dimensionadas para ajustarse a las paredes interiores del perfil de las barras a unir. La fijación de la pieza de entronque con los perfiles de las barras se lleva a cabo mediante unos tornillos pasantes, remaches o elementos similares insertados en orificios previstos al efecto en dicha pieza y de manera coincidente con otros orificios complementarios que se habrán practicado convenientemente en los extremos de las barras. With this, the connecting piece is introduced on both sides at the respective ends of the profiles and the inclination of the profiles is determined by the machining that has been performed on the fins of this piece, which will preferably be sized to fit the interior walls of the profile of the bars to be joined. The fixing of the connecting piece with the profiles of the bars is carried out by means of through screws, rivets or similar elements inserted in holes provided for that purpose in said piece and in a manner coinciding with other complementary holes that will have been conveniently practiced in the bar ends.
Con todo ello las ventajas que proporciona la pieza de entronque preconizada son: With all this, the advantages provided by the recommended piece of junction are:
- mayor fiabilidad en cuanto a resistencia, y menor coste de fabricación al consistir en una pieza que se obtiene por extrusión (hasta el momento se prepara por soldadura o por fundición); - greater reliability in terms of strength, and lower manufacturing cost by consisting of a piece that is obtained by extrusion (so far it is prepared by welding or casting);
- no altera la resistencia del entronque, puesto que el esqueleto no se modifica, ya que es el mecanizado de las aletas lo que permite conseguir el ángulo deseado;  - it does not alter the resistance of the junction, since the skeleton is not modified, since it is the machining of the fins which allows to achieve the desired angle;
- fácilmente desmontables al realizarse la fijación con ayuda de tornillos pasantes, remaches o similar;  - easily removable when fixing with the help of through screws, rivets or similar;
- evita reacciones entre materiales ya que permite la continuidad en el material, puesto que el material de la pieza de entronque y el material de las barras a unir puede ser el mismo.  - prevents reactions between materials as it allows continuity in the material, since the material of the junction piece and the material of the bars to be joined can be the same.
La descrita pieza de entronque para estructuras de barras consiste, pues, en una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. DESCRIPCIÓN DE LOS DIBUJOS The described piece of junction for bar structures consists, then, in an innovative structure of structural and constitutive characteristics unknown until now for the purpose to which it is intended, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las mencionadas figuras, y de acuerdo con la numeración adoptada, se puede apreciar en ellas un ejemplo de realización no limitativo de la pieza de la invención, la cual comprende las partes y elementos que se indican y describen en detalle a continuación. In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a non-limiting embodiment of the part of the invention can be seen, which comprises the parts and elements indicated and described in detail below.
Así, tal como se observa en dichas figuras, la pieza de entronque (1 ) en cuestión, aplicable para unir en ángulo variable los extremos de sendas barras (2) constituidas por respectivos perfiles extrusionados, consiste en una pieza obtenida por extrusión, que comprende un esqueleto (1 1 ), de configuración apta para caber dentro de la cavidad (21 ) interior de los perfiles de las barras (2) a unir, y cuya pieza (1 ) presenta externamente unas aletas longitudinales (12) susceptibles de ser mecanizadas para ajustarse a dicha cavidad y para otorgarles una determinada inclinación para adaptar el ángulo de unión entre las barras (2) al unirse con la pieza de entronque (1 ). Thus, as observed in said figures, the junction piece (1) in question, applicable to join at a variable angle the ends of two bars (2) constituted by respective extruded profiles, consists of a piece obtained by extrusion, comprising a skeleton (1 1), of configuration suitable to fit inside the cavity (21) inside the profiles of the bars (2) to be joined, and whose piece (1) externally presents longitudinal fins (12) capable of being machined to adjust to said cavity and to give them a certain inclination to adapt the angle of union between the bars (2) when joining with the piece of junction (1).
Dicha inclinación, es creciente o decreciente desde un punto central de la pieza (1 ) hacia los extremos distales de la misma y, preferentemente, simétrica. Said inclination is increasing or decreasing from a central point of the piece (1) towards the distal ends thereof and, preferably, symmetrical.
Las aletas longitudinales (12), preferentemente, son dos pares de aletas paralelas entre sí y que se sitúan de tal modo que quedan dos dimanando hacia un lado del esqueleto (1 1 ), por ejemplo el superior, y dos en el lado opuesto, el inferior. En cualquier caso estas aletas (12) están preferentemente dimensionadas para ajustarse a las paredes interiores de la cavidad (21 ) del perfil de las barras (2) a unir. The longitudinal fins (12), preferably, are two pairs of fins parallel to each other and positioned in such a way that there are two remaining towards one side of the skeleton (1 1), for example the upper one, and two on the opposite side, the bottom one In any case, these fins (12) are preferably sized to fit the interior walls of the cavity (21) of the profile of the bars (2) to be joined.
Por último, tal como se observa claramente en la figura 1 , la pieza de entronque (1 ) cuenta con una serie de orificios (3) en las paredes del esqueleto (1 1 ) que, situados en coincidencia con otros tantos orificios complementarios (3') previstos en los extremos del perfil que constituyen las barras (2) a unir, están destinados a la inserción de tornillos pasantes, remaches o elementos similares para llevar a cabo la fijación de la pieza de entronque (1 ) con dichos perfiles de las barras (2). Finally, as can be clearly seen in figure 1, the junction piece (1) has a series of holes (3) in the skeleton walls (1 1) which, located in coincidence with as many complementary holes (3) ') provided at the ends of the profile that constitute the bars (2) to be joined, are intended for the insertion of through screws, rivets or similar elements to carry out the fixation of the piece of connection (1) with said profiles of the bars (2).
Como se observa en la figura 4, dichos orificios (3) de la pieza de entronque (1 ) están dispuestos en dos grupos alineados con la misma inclinación que adoptarán cada uno de los dos perfiles de las barras (2) al acoplarse a la pieza, es decir, con la inclinación determinada por el corte mecanizado que se ha practicado a las aletas (12) de la pieza, habiéndose representado en dicha figura 4, mediante líneas de trazo discontinuo y con la referencia (121 ), la porción de material mecanizado de las aletas de la pieza para facilitar la comprensión de la explicación. As can be seen in Figure 4, said holes (3) of the connecting piece (1) are arranged in two groups aligned with the same inclination that each of the two profiles of the bars (2) will adopt when they are coupled to the piece. , that is, with the inclination determined by the mechanized cut that has been made to the fins (12) of the piece, having been represented in said figure 4, by dashed lines and with reference (121), the portion of material machining of the fins of the piece to facilitate the understanding of the explanation.
En definitiva, la pieza de entronque (1 ) propuesta, aplicable para unir en ángulo variable los extremos de dos barras (2) constituidas por perfiles extrusionados, consiste en una pieza fabricada por extrusión con zonas mecanizadas para ajustarse a dichos perfiles de dichas barras (2) a unir determinando el ángulo de unión de las mismas. Y, preferentemente, dichas zonas mecanizadas son las anteriormente descritas aletas longitudinales (12) que presenta exteriormente el esqueleto (1 1 ) y que están mecanizadas con una determinada inclinación según el ángulo de unión deseado. In short, the proposed junction piece (1), applicable to join at a variable angle the ends of two bars (2) constituted by extruded profiles, consists of a piece manufactured by extrusion with machined areas to fit said profiles of said bars ( 2) to join determining the angle of union of the same. And, preferably, said machined areas are the aforementioned longitudinal fins (12) which the skeleton (1 1) has externally and which are machined with a certain inclination according to the desired joint angle.
En una realización preferida, los perfiles extrusionados que constituyen las barras (2) a unir y la pieza son del mismo material. Así si las barras (2) son de aluminio, para dar ligereza y resistencia a la estructura a conformar, la pieza de entronque (1 ) es también un perfil extrusionado de aluminio. In a preferred embodiment, the extruded profiles that constitute the bars (2) to be joined and the part are of the same material. Thus, if the bars (2) are made of aluminum, to give lightness and resistance to the structure to be formed, the fitting (1) is also an extruded aluminum profile.
