DESCRIPCIÓN DESCRIPTION

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La siguiente invención se refiere a un procedimiento de fabricación de un perfil tubular y perfil tubular obtenido, teniendo por objeto esencial la configuración de un perfil tubular basado en un núcleo central y una envolvente, a base de respectivas parejas de láminas dobladas a 90°, cuyas parejas de láminas, una vez dobladas a 90°, se solidarizan entre sí, y se fijan entre ellas por medio de una pluralidad de elementos rigidizadores en sentido longitudinal y transversal. The following invention relates to a method of manufacturing a tubular profile and tubular profile obtained, having as essential object the configuration of a tubular profile based on a central core and an envelope, based on respective pairs of sheets folded at 90 °, whose pairs of sheets, once folded at 90 °, are in solidarity with each other, and are fixed between them by means of a plurality of stiffeners in longitudinal and transverse directions.

De esta forma, el perfil final obtenido se basa en un perfil tubular con un núcleo central y una envolvente, cuyo núcleo central y envolvente quedan solidarizados entre ellos por una pluralidad de elementos rigidizadores en sentido longitudinal y transversal. In this way, the final profile obtained is based on a tubular profile with a central core and an envelope, whose central core and envelope are joined together by a plurality of longitudinal and transverse stiffening elements.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Como es conocido, una importante cantidad de obras, de todo tipo, que nos rodean se conforman en hormigón armado, de forma que la estructura de hierro armado, conocida como ferralla, siendo la ferralla uno de los elementos más importantes en el sector de la construcción al ser utilizado para reforzar estructuras de hormigón. As is known, an important amount of works, of all kinds, that surround us are made of reinforced concrete, so that the structure of reinforced iron, known as ferralla, being the ferralla one of the most important elements in the sector of the construction when used to reinforce concrete structures.

Así, el hierro armado resulta de la unión de una serie de barras de acero de distintas longitudes, formas y diámetros, provistas de una pluralidad de resaltes o corrugas, mediante las que se mejora la adherencia del hormigón, y cuya serie de barras de acero quedan unidas mediante unos alambres u otros medios equivalentes. Thus, reinforced iron results from the union of a series of steel bars of different lengths, shapes and diameters, provided with a plurality of projections or corrugations, by which the adhesion of concrete is improved, and whose series of steel bars they are joined by wires or other equivalent means.

De esta forma, la armadura definida se adapta a la estructura de hormigón a configurar, y, así, se puede utilizar para la creación de pilares, forjados, cimentaciones, muros, etc, de manera que asociada a dicha armadura se materializa el oportuno encofrado, el cual se puede llevar a cabo por medio de unas placas de madera o metálicas, y el posterior vertido del hormigón en la estructura definida por el encofrado, manteniendo dicha estructura hasta el fraguado del hormigón momento en el que se deberá proceder a su desencofrado. In this way, the defined reinforcement adapts to the concrete structure to be configured, and, thus, can be used for the creation of pillars, slabs, foundations, walls, etc., so that the appropriate formwork materializes associated with said reinforcement , which can be carried out by means of wooden or metal plates, and the subsequent pouring of concrete into the structure defined by the formwork, maintaining said structure until the setting of the concrete moment in which it will be necessary to remove them.

Con objeto de llevar a cabo todo el proceso, por un lado se debe de proceder a la fabricación de las correspondientes estructuras de hierro armado, su transporte a la obra a ejecutar, su montaje y posterior definición del encofrado, generalmente, a base de placas de madera o metálicas, colocando los respectivos elementos de fijación de las mismas para soportar la presión que vaya a ejercer el hormigón a verter en el hueco definido. In order to carry out the entire process, on the one hand, the corresponding reinforced iron structures must be manufactured, transported to the work to be carried out, their assembly and subsequent definition of the formwork, generally based on plates of wood or metal, placing the respective fixing elements thereof to withstand the pressure to be exerted by the concrete to be poured into the defined hole.

Una vez fraguado el hormigón se deberá proceder al desencofrado de la estructura relativa al encofrado conformado, lo que lleva una considerable mano de obra y un riesgo de posibles accidentes, principalmente, cuando se trate de encofrados de forjado que, normalmente, son liberados al suelo directamente. Once the concrete has been set, the structure related to the formed formwork must be removed, which leads to considerable labor and a risk of possible accidents, especially when it comes to floor slabs that are normally released to the ground. directly.

A todo ello hay que añadir la presencia de placas en toda la zona de trabajo, pudiendo encontrarse algunas de ellas rotas o deterioradas, así como el tiempo invertido en la retirada de las mismas. To all this we must add the presence of plates throughout the work area, being able to find some of them broken or damaged, as well as the time invested in their removal.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE DESCRIPTION OF A PREFERRED EMBODIMENT

A la vista de las comentadas figuras y de acuerdo con la numeración adoptada podemos observar como el objeto del procedimiento de la invención se basa en la fabricación de un perfil tubular conformado por un núcleo central y una envolvente, de utilidad, preferente, en la industria de la construcción, de forma que el procedimiento consiste en la obtención de unas parejas de láminas 1 y 1’ que tras su corte, a las medidas apropiadas, se procede a materializar una serie de troquelados, de forma general rectangular alargada, en sentido longitudinal 2 y transversal 3, alineados longitudinalmente. In view of the aforementioned figures and in accordance with the numbering adopted, we can observe how the object of the process of the invention is based on the manufacture of a tubular profile formed by a central core and an envelope, useful, preferred, in industry. of the construction, so that the procedure consists in obtaining a pair of sheets 1 and 1 'that after their cut, to the appropriate measures, a series of punches, generally rectangular elongated, in longitudinal direction are materialized 2 and transverse 3, aligned longitudinally.

Así, las parejas de láminas 1 conformantes del núcleo central 7 tendrán menores dimensiones que las parejas de láminas T conformantes de la envolvente 8, de manera que los troquelados en sentido longitudinal 2 y transversal 3, en el montaje para la obtención del perfil, quedarán en correspondencia unos con otros. Thus, the pairs of sheets 1 forming the central core 7 will have smaller dimensions than the pairs of sheets T forming the envelope 8, so that the punched in longitudinal direction 2 and transverse 3, in the assembly to obtain the profile, will remain in correspondence with each other.

Por otra parte, se procede a la obtención de unos elementos rigidizadores longitudinales 4 y transversales 5, los cuales se encajarán y fijarán en los correspondientes troquelados longitudinales 2 y transversales 3 de las parejas de láminas 1 y 1’ conformantes del perfil tubular 6. On the other hand, we proceed to obtain longitudinal and transverse stiffener elements 4, which will fit and fix in the corresponding longitudinal and transverse punches 3 of the pairs of sheets 1 and 1 ’forming the tubular profile 6.

Los rigidizadores longitudinales 4 se definen por unas primeras pletinas, de forma general rectangular, provistas en sus lados laterales extremos de respectivos entrantes 9, cuyos entrantes 9 harán de tope sobre la correspondiente cara de la lámina 1 y 1’ entre la que quedan dispuestos, en tanto que el saliente central definido encaja en el troquelado longitudinal 2, respectivo. The longitudinal stiffeners 4 are defined by first plates, generally rectangular in shape, provided on their lateral sides with respective recesses 9, whose recesses 9 will abut the corresponding face of the sheet 1 and 1 'between which they are arranged, while the defined central projection fits in the respective longitudinal die 2.

Los rigidizadores transversales 5 de definen por unas segundas pletinas, de forma general rectangular, que en proximidad a uno de sus extremos presentan sendos pequeños salientes 10, de tope sobre las láminas 1 conformantes del núcleo central 7, en tanto que su extremo opuesto se encajará a“medio grueso” en el correspondiente troquelado de la envolvente 8 para proceder, posteriormente, a su fijación por soldadura. The transverse stiffeners 5 are defined by second plates, generally rectangular in shape, which in proximity to one of their ends have small protrusions 10, butt on the sheets 1 forming the central core 7, while their opposite end will fit to "coarse medium" in the corresponding die cut of the envelope 8 to subsequently proceed to its welding fixation.

Asimismo, los elementos rigidizadores longitudinales 4 y transversales 5 están provistos de una serie de orificios, de forma que, a través de ellos, se facilitará el paso del hormigón en el vibrado del mismo. Likewise, the longitudinal and transverse stiffener elements 5 are provided with a series of holes, so that, through them, the passage of concrete in the vibrating of it will be facilitated.

Una vez obtenidas las parejas de láminas 1 y 1’ conformantes del núcleo 7 y la envolvente 8 se procederá al plegado de las mismas a 90°, para, a continuación, proceder al encaje y fijación, de los elementos rigidizadores longitudinales 4 y transversales 5 en los respectivos troquelados longitudinales 2 y transversales 3 de la pareja de láminas 1 conformantes del núcleo 7, por sus caras externas. Once the pairs of sheets 1 and 1 'forming the core 7 and the shell 8 are obtained, they will be folded at 90 °, then proceed to fit and fix the longitudinal stiffening elements 4 and transverse 5 in the respective longitudinal and transverse punches 2 of the pair of sheets 1 forming the core 7, by their external faces.

A continuación se procederá a la unión, preferentemente soldada, a canto vivo, de la pareja de láminas 1 conformantes del núcleo 7 y portadoras de los respectivos elementos rigidizadores longitudinales 4 y transversales 5, fijados a ellas, definiendo de esta forma el núcleo 7. Next, the union, preferably welded, of the pair of sheets 1 forming the core 7 and bearing the respective longitudinal stiffener elements 4 and transverse 5, fixed thereto, will then proceed, thus defining the core 7.

De esta forma, técnicamente, las aristas curvas incrementan su rigidez, ya que, en ellas las fibras del material se reorganiza interna y estructuralmente. In this way, technically, the curved edges increase their rigidity, since, in them the fibers of the material are internally and structurally reorganized.

Tras la configuración del núcleo 7 se procederá al montaje de la envolvente 8, de manera que, en primer lugar, se dispondrá una lámina T, conformante de la envolvente 8, doblada a 90°, haciendo que los correspondientes rigidizadores longitudinales 4 y transversales 5 solidarios al núcleo 7, encajen, a medio grueso, en los respectivos troquelados practicados al efecto en sus dos caras para, a continuación, proceder a su fijación, preferentemente, soldada. After the configuration of the core 7, the envelope 8 will be assembled, so that, first, a sheet T, forming the envelope 8, bent at 90 °, will be arranged, making the corresponding longitudinal and transverse stiffeners 4 attached to the core 7, fit, with a medium thickness, in the respective die cuttings made for this purpose on both sides, then proceed to fix it, preferably, welded.

Así, una vez fijada una primera lámina T doblada a 90° conformante de la envolvente 8 al núcleo 7, se procederá al montaje de la segunda lámina T conformante de la envolvente 8, llevando a cabo el encaje de los respectivos elementos rigidizadores longitudinales 4 y transversales 5 solidarios al núcleo 7, en los troquelados practicados el efecto en la misma, para a continuación proceder a su fijación, preferentemente, por soldadura. Thus, once a first sheet T folded at 90 ° forming the shell 8 is fixed to the core 7, the second sheet T forming the shell 8 will be assembled, fitting the respective longitudinal stiffening elements 4 and transverse 5 integral to the core 7, in the stamped ones, the effect thereof, to then proceed to its fixation, preferably, by welding.

Finalmente, se procederá a unir ambas láminas T dobladas a 90°, conformantes de la envolvente 8, preferentemente, por soldadura por sus cantos vivos, habiendo materializado el perfil tubular 6 objeto de la invención. Finally, both sheets T folded at 90 ° will be joined, forming the envelope 8, preferably, by welding by their live edges, the tubular profile 6 object of the invention having materialized.

En la ejecución de la envolvente 8 se deberá tener presente que la arista redondeada de la pareja de láminas 1’ dobladas a 90°, conformantes de la misma queden en relación con las aristas unida a canto vivo de la pareja de láminas 1 conformantes del núcleo 7. In the execution of envelope 8, it should be borne in mind that the rounded edge of the pair of sheets 1 'folded at 90 °, conformers thereof are in relation to the edges joined to the living edge of the pair of sheets 1 forming the core 7.

De esta forma, obtenemos un perfil tubular 6 definido por un núcleo 7 y una envolvente 8, definidas por una pareja de láminas dobladas a 90°, cada una de ellas, unidas entre sí por sus aristas libres, y que, a su vez, quedan unidas entre ellas por una pluralidad de elementos rigidizadores en sentido longitudinal y transversal. In this way, we obtain a tubular profile 6 defined by a core 7 and an envelope 8, defined by a pair of sheets folded at 90 °, each of them, joined together by their free edges, and which, in turn, they are joined together by a plurality of longitudinally and transversely stiffener elements.

Por otra parte, el perfil tubular 6 definido puede ser sometido a distintos tratamientos, tales como galvanizado o pintado, pudiendo quedar a la vista y pudiendo utilizarse para otros fines, tales como depósitos, quedando debidamente cerrados por sus bases. On the other hand, the defined tubular profile 6 can be subjected to different treatments, such as galvanized or painted, being able to be seen and can be used for other purposes, such as deposits, being duly closed by its bases.

Así, el perfil tubular 6 obtenido en su utilización en la construcción actúa como elemento de encofrado, ya que, por ejemplo, en la ejecución de pilares, el vertido de hormigón se podrá llevar a cabo en la zona relativa al núcleo central y en la zona definida entre el núcleo central 7 y la envolvente 8, quedando a fondo perdido, de manera que de esta forma se evita la mano de obre precisa en la ejecución del encofrado y su desmontaje, así como la rotura o deterioro de los materiales, tales como placas de madera o metálicas, empleados, convencionalmente, en la ejecución del encofrado. Asimismo, el vertido de hormigón se podrá realizar, únicamente, en el contorne existente entre el núcleo central y la envolvente creando estructuras huecas. Thus, the tubular profile 6 obtained in its use in construction acts as a formwork element, since, for example, in the execution of pillars, concrete pouring can be carried out in the area relative to the central core and in the defined area between the central core 7 and the envelope 8, being thoroughly lost, so that the precise workmanship in the formwork execution and its disassembly, as well as the breakage or deterioration of the materials, such, is avoided as wood or metal plates, conventionally used in the formwork. Likewise, concrete pouring can only be carried out on the contour between the central core and the envelope creating hollow structures.

Lógicamente, el perfil tubular 6 podrá tener una sección general rectangular o cuadrada, y, asimismo, podrá tener una forma general troco piramidal, siendo de gran utilidad para la creación de torres para distintos usos, pudiendo, además, quedar su parte central hueca, ya que, unos perfiles se podrán unir a otros por distintos medios, tal como por tornillería, pudiendo lograr la altura deseada. Igualmente, se podrán configurar estructuras alabeadas, teniendo en cuenta que los troquelados longitudinales y transversales practicados en las láminas conformantes de su estructura queden siempre coincidentes entre sí. Logically, the tubular profile 6 may have a general rectangular or square section, and, likewise, it may have a general pyramid shape, being very useful for the creation of towers for different uses, and its hollow central part may also be left, since, some profiles can be joined to others by different means, such as screws, being able to achieve the desired height. Likewise, warped structures may be configured, taking into account that the longitudinal and transverse die cuts made in the forming sheets of its structure are always coincident with each other.

La estructura obtenida mediante el perfil tubular 6 es, en sí misma, una estructura auto portante de gran resistencia. The structure obtained by the tubular profile 6 is, in itself, a self-supporting structure of great strength.

Asimismo, en la zona definida entre el núcleo central 7 y la envolvente 8 podrá disponerse un aislamiento térmico. Por otra parte, las caras de las parejas de láminas 1 y 1’ que vayan a quedar en contacto con el hormigón, así como los elementos rigidizadores longitudinales 4 y transversales 5 podrán disponer en su superficie distintas formas de corrugados aumentando de esa manera la adherencia del hormigón. Likewise, a thermal insulation can be provided in the defined area between the central core 7 and the enclosure 8. On the other hand, the faces of the pairs of sheets 1 and 1 'that are to be in contact with the concrete, as well as the longitudinal stiffener elements 4 and transverse 5 may have different corrugated forms on their surface thereby increasing the adhesion of concrete.

Los troquelados transversales pueden practicarse abarcando una ligera anchura mayor al grosor de los troquelados longitudinales y practicando uno por cada alineación de troquelados longitudinales, tal como se representa en la figura 3 de los diseños. Transversal punches can be practiced by covering a slight width greater than the thickness of the longitudinal punches and practicing one for each alignment of longitudinal punches, as shown in Figure 3 of the designs.
