OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un encofrado, de los utilizados en la construcción para la ejecución de pilares prismáticos, preferentemente de sección cuadrangular, aunque podría ser aplicable a la ejecución de pilares con cualquier sección poligonal, con o sin sus vértices truncados, encofrado de carácter mono-uso, eliminable en el momento del desencofrado de la columna.The present invention relates to a formwork, of those used in construction for the execution of prismatic pillars, preferably of quadrangular section, although it could be applicable to the execution of pillars with any polygonal section, with or without its truncated vertices, formwork mono-use character, removable at the time of decoupling the column.
El objeto de la invención es proporcionar un encofrado plegable, de extrema ligereza, que se sirva totalmente terminado, es decir que no necesite de mano de obra especializada para su montaje, así como de materiales adicionales tales como tiras adhesivas o similares, ni de fases de montaje intermedias, de manera que su montaje final en obra sea sumamente sencillo, con una distribución equiangular entre las caras verticales del prisma correspondiente a la columna o pilar a realizar, así como facilitar la estabilización del dispositivo en su lugar de emplazamiento y posicionar perfectamente los vértices de cada columna según la orientación que se pretenda obtener.The object of the invention is to provide a foldable formwork, of extreme lightness, that is served completely finished, that is to say that it does not need specialized labor for its assembly, as well as additional materials such as adhesive or similar strips, or phases of intermediate assembly, so that its final assembly on site is extremely simple, with an equiangular distribution between the vertical faces of the prism corresponding to the column or pillar to be performed, as well as facilitating the stabilization of the device in its place of placement and positioning perfectly the vertices of each column according to the orientation to be obtained.
ANTECEDENTES DE LA INVENCIÓN Son conocidos numerosos tipos de encofrados para columnas prismáticas a base de una envolvente tubular, cilindrica de suficiente rigidez, con un núcleo también tubular, exteriormente cilindrico en correspondencia con la citada envolvente e interiormente prismático, en correspondencia con la columna a obtener, con su superficie interna dotada de un revestimiento a base de una lámina plástica o similar, en cualquier caso adecuada para evitar que la humedad de los materiales constitutivos de la columna puedan dañar a su vez la estructura del encofrado, mientras éste cumple su función.BACKGROUND OF THE INVENTION Numerous types of formwork are known for prismatic columns based on a tubular, cylindrical shell of sufficient rigidity, with a tubular core, externally cylindrical in correspondence with the aforementioned envelope and internally prismatic, in correspondence with the column to be obtained, with its surface internal endowed with a coating based on a plastic sheet or similar, in any case suitable to prevent moisture from the constituent materials of the column in turn damage the formwork structure, while it fulfills its function.
La envolvente exterior se materializa generalmente en un complejo a base de cartón, plástico y aluminio, mientras que el núcleo tubular interior está obtenido a base de cuatro segmentos cilindricos de poliestireno expandido de alta densidad, debidamente forrados, bien directamente unidos por sus aristas o bien con éstas sensiblemente distanciadas para conseguir chaflanes en correspondencia con las aristas de la columna.The outer shell generally materializes in a complex based on cardboard, plastic and aluminum, while the inner tubular core is obtained based on four cylindrical segments of high density expanded polystyrene, properly lined, either directly joined by its edges or with these substantially distanced to achieve chamfers in correspondence with the edges of the column.
De la estructuración descrita se deduce que el encofrado sale de fábrica con una configuración cilindrica de diámetro ligeramente mayor que la diagonal de la columna a obtener, es decir que la volumetría del encofrado es exactamente la misma cuando se encuentra en situación de almacenaje y transporte que cuando se encuentra en situación de uso.From the structuring described it follows that the formwork leaves the factory with a cylindrical configuration of slightly larger diameter than the diagonal of the column to be obtained, that is to say that the volumetry of the formwork is exactly the same when it is in a storage and transport situation that when it is in use situation.
Tratando de obviar este problema de almacenaje y transporte, son conocidos encofrados del tipo anteriormente citado en los que tanto la envolvente exterior como el núcleo tubular están afectados por un corte en sentido de sus generatrices, que permite almacenar y transportar ambos elementos independizados entre sí y que por otro lado permite introducir unas envolventes dentro de otras, para minimizar su ocupación de espacio, y machihembrar en cierta medida también sus núcleos interiores, con la misma finalidad. Sin embargo esta solución presente un problema de capital importancia y es que el encofrado así estructurado no puede ser directamente utilizado por el constructor, siendo necesaria una fase operativa intermedia, a realizar generalmente por una empresa colaboradora del fabricante, que cierra el núcleo tubular sobre sí mismo, por ejemplo mediante una tira adhesiva que se monta simultáneamente sobre la zona marginal de los bordes de la lámina plástica interior a dicho núcleo, a la vez que exteriormente se estabiliza con la colaboración de una segunda cinta adhesiva, generalmente arrollada de forma helicoidal.Trying to obviate this storage and transportation problem, formwork of the aforementioned type are known in which both the outer envelope and the tubular core are affected by a cut in the direction of their generatrices, which allows both independent elements to be stored and transported and that on the other hand allows to introduce envelopes within others, to minimize their occupation of space, and to tongue and groove to some extent also their inner nuclei, with the same purpose. However, this solution presents a problem of major importance and is that the formwork thus structured cannot be used directly by the builder, being necessary an intermediate operational phase, generally performed by a company collaborating with the manufacturer, which closes the tubular core on itself same, for example by means of an adhesive strip that is mounted simultaneously on the marginal zone of the edges of the inner plastic sheet to said core, while at the same time externally it is stabilized with the collaboration of a second adhesive tape, generally helically wound.
Esto supone un notable incremento de costos, una pérdida de tiempo que retrasa la entrega de los encofrados y sobre todo una pérdida en la continuidad superficial interna del encofrado que va a repercutir posterior y negativamente en el aspecto estético de la columna a obtener.This implies a notable increase in costs, a loss of time that delays the delivery of the formwork and, above all, a loss in the internal surface continuity of the formwork that will subsequently and negatively affect the aesthetic aspect of the column to be obtained.
A fin de solucionar estos problemas, el propio solicitante es titular de la patente de invención PCT/ES2004/000235 en la que se describe un encofrado del tipo de los anteriormente citados, pero que presenta como particularidad el hecho de que el núcleo tubular resulta plegable en fase de almacenaje y transporte, con una notable reducción volumétrica, contando Ia funda exterior con al menos un corte en el sentido de una de sus generatrices, que permite su montaje y desmontaje sobre el núcleo tubular en el momento de utilización del encofrado con la colaboración de cinchas o elementos de cierre que mantienen la funda tubular inmovilizada, en su posición de trabajo o vertido del hormigón.In order to solve these problems, the applicant himself is the holder of the invention patent PCT / ES2004 / 000235 in which a formwork of the type mentioned above is described, but which features the fact that the tubular core is collapsible in storage and transport phase, with a notable volumetric reduction, counting The outer sheath with at least one cut in the direction of one of its generatrices, which allows its assembly and disassembly on the tubular core at the time of use of the formwork with the collaboration of straps or closure elements that keep the tubular sheath immobilized, in its working position or pouring concrete.
Dichos elementos de cierre pueden materializarse en cinchas o en aros metálicos que se disponen abrazando exteriormente el encofrado. El problema fundamental que presenta el citado encofrado es la complejidad de montaje de dichos elementos de cierre cuando éstos se materializan en aros metálicos, puesto que el diámetro interior de dichos anillos debe ser igual al diámetro exterior de la funda exterior del núcleo tubular, en orden a que no existan holguras en su montaje, lo que dificulta seriamente las maniobras de inserción de dichos aros sobre la envolvente del núcleo tubular, maniobra que debe ser realizada por personal cualificado, con la consiguiente pérdida de tiempo y costes asociados que ello conlleva.Said closure elements can be realized in webbing or in metal rings that are arranged by externally embracing the formwork. The fundamental problem presented by the aforementioned formwork is the complexity of assembly of said closure elements when they are materialized in metal rings, since the inner diameter of said rings must be equal to the outer diameter of the outer sheath of the tubular core, in order to that there are no gaps in its assembly, which seriously hinders the maneuvers of insertion of said rings on the envelope of the tubular core, maneuver that must be performed by qualified personnel, with the consequent loss of time and associated costs that this entails.
Asimismo, cabe destacar que cuando dichos elementos de cierre se materializan en cinchas dotadas de elementos tensores o similares, la falta de rigidez de dichos elementos impide asegurar el correcto posicionamiento y armado del encofrado, pudiendo las paredes internas o correspondientes al pilar prismático a realizar no presentar el correcto paralelismo o equiangularidad entre sus caras.Likewise, it should be noted that when said closing elements are materialized in straps equipped with tensioning elements or the like, the lack of stiffness of said elements prevents ensuring the correct positioning and assembly of the formwork, the internal walls or corresponding to the prismatic pillar being able to perform not present the correct parallelism or equiangularity between their faces.
DESCRIPCIÓN DE LA INVENCIÓN El encofrado para columnas prismáticas que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en cada uno de los aspectos comentados.DESCRIPTION OF THE INVENTION The formwork for prismatic columns that the invention proposes solves in a fully satisfactory way the problem previously stated, in each of the aspects mentioned.
Para ello y partiendo de la configuración anteriormente descrita, en la que participa un núcleo tubular interior plegable, a base de cuatro o más segmentos cilindricos de productos termoconfbrmados ligeros, en función de la configuración prismático poligonal que se le quiera dar a la columna o pilar a realizar, segmentos cilindricos que se fijan por su cara curva exteriormente sobre una envolvente igualmente exterior de un material suficientemente resistente y flexible, por ejemplo tejido de rafia, papel kraft, etc, de configuración cilindrica, que puede adoptar una configuración aplanada, merced a las aristas de unión de los segmentos cilindricos fijados a la misma, segmentos que incorporan al menos un revestimiento estanco sobre su cara interna en orden a estanqueizar convenientemente la cámara o receptáculo en la que va a formarse la columna, la cual puede presentar o no sus aristas achaflanadas, la invención centra sus características en el hecho de que dicho encofrado se suministra junto con una pieza anular, laminar, de configuración acorde con la geometría de la columna o pilar a obtener, pieza obtenida a partir de cartón, madera, plástico o cualquier material que aporte la debida rigidez al citado elemento, cuya sección interior presentará unas dimensiones acordes con las de la columna a obtener, y de dimensiones externas adecuadas para permitir estabilizar el encofrado en situación de montaje, como se verá más adelante.To do this and based on the configuration described above, in which a foldable inner tubular core participates, based on four or more cylindrical segments of lightweight thermoformed products, depending on the polygonal prismatic configuration that you want to give to the column or pillar to be made, cylindrical segments that are fixed on its externally curved face on an equally outer envelope of a sufficiently resistant and flexible material, for example raffia fabric, kraft paper, etc., of cylindrical configuration, which can adopt a flattened configuration, thanks to the joining edges of the cylindrical segments fixed thereto, segments that incorporate at least one watertight coating on its inner face in order to conveniently seal the chamber or receptacle in which the column is to be formed, which may or may not present its chamfered edges, the invention focuses its characteristics on the fact that said formwork It is supplied together with an annular, laminar piece, of configuration according to the geometry of the column or pillar to be obtained, piece obtained from cardboard, wood, plastic or any material that provides due rigidity to said element, whose interior section will present dimensions in accordance with those of the column to be obtained, and of suitable external dimensions to allow the formwork to be stabilized in a mounting situation, as will be seen later.
Como complemento de la estructura descrita, las caras interiores del encofrado se prolongan en pestañas abatibles, de manera que en el momento del despliegue del encofrado, dichas pestañas se introducen en el seno de la pieza anular, de manera que para que se pueda producir dicho acoplamiento, el encofrado tiene que presentar la configuración exacta de montaje para el vertido del hormigón o masa de que se trate, asegurando una perfecta coplanariedad entre caras enfrentadas del prisma constitutivo de la columna.As a complement to the structure described, the inner faces of the formwork they extend in folding eyelashes, so that at the time of the deployment of the formwork, said eyelashes are introduced inside the annular piece, so that in order for said coupling to be produced, the formwork must have the exact configuration of assembly for the pouring of the concrete or mass in question, ensuring a perfect coplanarity between facing faces of the constituent prism of the column.
Así pues, el encofrado se suministrará con dos piezas anulares, a las que se acoplarán interiormente las pestañas que emergen de ambos extremos del encofrado, habiéndose previsto que para una mayor estabilización, dichas aletas se pliegan hacia fuera, sobre la citada pieza anular, fijándose a ésta mediante cualquier medio convencional, tal como grapas, clavos, adhesivos, etc.Thus, the formwork will be supplied with two annular pieces, to which the tabs that emerge from both ends of the formwork will be fitted internally, it being provided that for greater stabilization, said fins fold outwardly, on said annular piece, being fixed to it by any conventional means, such as staples, nails, adhesives, etc.
Una vez fijadas las aletas a las piezas anulares, el encofrado podrá fijarse o inmovilizarse al suelo a través de dichas piezas anulares, evitando que éste se mueva durante la obtención de la columna de que se trate, mediante apuntalamiento, con tablas o cualquier medio convencional.Once the fins are fixed to the annular pieces, the formwork can be fixed or immobilized to the ground through said annular pieces, preventing it from moving during the obtaining of the column in question, by shoring, with boards or any conventional means .
De acuerdo con otra de las características de la invención, las citadas piezas anulares presentarán unas marcas sobre su superficie indicativas del posicionamiento exacto de cada uno de los vértices del pilar o columna a obtener, en orden a permitir la colocación y alineación exacta del encofrando en el replanteo de la obra asegurando el paralelismo entre pilares contiguos. DESCRIPCIÓN DE LOS DIBUJOSAccording to another of the characteristics of the invention, said annular pieces will have markings on their surface indicating the exact positioning of each of the vertices of the pillar or column to be obtained, in order to allow the exact placement and alignment of the formwork in the rethinking of the work ensuring the parallelism between adjacent pillars.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como el encofrado que se preconiza parte de la estructura básica de los encofrados anteriormente citados, constituidos a partir de un núcleo tubular (1), que define interiormente un alojamiento prismático (2), en el ejemplo de realización práctica elegido prismático-cuadrangular, pero que podría adoptar cualquier otra configuración prismático-poligonal, núcleo (1) exteriormente cilindrico, a base de segmentos cilindricos de poliuretano expandido u otro material ligero similar, con un revestimiento estanco (3) interior, en orden a estanqueizar convenientemente la cámara o alojamiento (2), quedando dicho núcleo alojado y estabilizado en el seno de una envolvente (4), de un material suficientemente resistente, como por ejemplo a base de papel, plástico y aluminio, sin que este producto sea en modo alguno limitativo, y dotado de zonas de abisagramiento correspondientes con las aristas (5) de la columna prismática a realizar para el plegado del encofrado en situación de almacenaje o transporte con una ocupación volumétrica mínima.In view of the aforementioned figures, it can be seen how the formwork that is recommended as part of the basic structure of the aforementioned formwork, constituted from a tubular core (1), which internally defines a prismatic housing (2), in the example of practical realization chosen prismatic-quadrangular, but that could adopt any other prismatic-polygonal configuration, externally cylindrical core (1), based on cylindrical segments of expanded polyurethane or other similar lightweight material, with a watertight inner lining (3), in order to conveniently seal the chamber or housing (2), said core being housed and stabilized within an envelope (4), of a sufficiently resistant material, such as based on paper, plastic and aluminum, without this product be in any way limiting, and equipped with hinge areas corresponding to the edges (5) of the prismatic column to be performed r for folding the formwork in storage or transport situation with a minimum volumetric occupancy.
A partir de la estructuración anteriormente descrita, el encofrado de la invención centra sus características en el hecho de que la envolvente interior (3), determinante de cada una de las caras de la columna prismática a obtener, se prolonga más allá de las bases superior e inferior del encofrado en aletas (6) que en el ejemplo de realización práctica elegido adoptan una configuración trapecial isoscélica, pero que igualmente podrían adoptar una configuración rectangular, sin que ello afectase a la esencia de la invención.From the structure described above, the formwork of the invention focuses its characteristics on the fact that the inner envelope (3), determinant of each of the faces of the prismatic column to be obtained, extends beyond the upper and lower bases of the fin formwork (6) that in the example of practical implementation chosen they adopt an isoscelic trapezoidal configuration, but they could also adopt a rectangular configuration, without affecting the essence of the invention.
Como complemento de la estructura descrita, el encofrado se complementa con una pareja de cuerpos anulares (7), en este caso cuadrangulares, en cualquier caso siempre con la geometría acorde a la sección de la columna a obtener, cuerpo anular (7) laminar, obtenido a base de cartón, plástico, madera u otro material que presente una rigidez adecuada, cuyas dimensiones internas estarán adecuadas a las dimensiones de la citada columna, y cuyo grosor será suficiente como para determinar los medios de estabilización del encofrado, de manera que la longitud de las citadas aletas será adecuada al citado grosor del cuerpo anular (7).As a complement to the structure described, the formwork is complemented with a pair of annular bodies (7), in this case quadrangular, in any case always with the geometry according to the section of the column to be obtained, annular body (7) laminar, obtained based on cardboard, plastic, wood or other material that has adequate rigidity, whose internal dimensions will be adequate to the dimensions of the said column, and whose thickness will be sufficient to determine the means for stabilizing the formwork, so that the The length of said fins will be appropriate to the aforementioned thickness of the annular body (7).
De forma más concreta, y como puede observarse en la secuencia de las figuras 1 a 5, una vez desplegado el encofrado, se presiona éste para que las aletas (6) adopten una disposición en la que las mismas quedan enfrentadas dos a dos, formando planos ortogonales entre las aletas contiguas," tal como muestra la figura 2, para en esa posición, ajustar sobre dichas aletas, tanto en las correspondientes a la extremidad superior como a la inferior del encofrado el citado cuerpo anular (7), apoyando sobre las extremidades o bases de núcleo (1), posición en la que, una vez montado cada cuerpo (7), se garantiza la equiangularidad entre las caras internas del encofrado, determinantes de la columna a obtener.More specifically, and as can be seen in the sequence of Figures 1 to 5, once the formwork is deployed, it is pressed so that the fins (6) adopt an arrangement in which they are facing two to two, forming orthogonal planes between adjacent fins, " as shown in Figure 2, to adjust in that position, on said fins, both those corresponding to the upper and lower extremities of the formwork, the said annular body (7), resting on the limbs or core bases (1), position in which, Once each body (7) is assembled, the equiangularity between the internal faces of the formwork, which determine the column to be obtained, is guaranteed.
Seguidamente, y tal y como muestra la figura 4, se procede a doblar las aletas sobre la superficie de cada uno de los lados cuerpo anularThen, and as shown in Figure 4, the fins are folded over the surface of each of the annular body sides
(7), fijándose a éste mediante adhesivo, grapado, clavos o cualquier otro medio convencional.(7), fixing it by means of adhesive, stapling, nails or any other conventional means.
Una vez realizado este proceso sobre ambos extremos del encofrado, éste puede ser estabilizado sobre su lugar de implantación mediante apoyo del mismo sobre el citado cuerpo anular (7), que actúa a modo de base sustentadora, la cual puede fijarse al suelo mediante apuntalado, con el concurso de tablas, o mediante cualquier otro medio convencional.Once this process has been carried out on both ends of the formwork, it can be stabilized on its place of implantation by supporting it on the said annular body (7), which acts as a support base, which can be fixed to the ground by means of shoring, with the contest of tables, or by any other conventional means.
A fin de permitir identificar fácilmente y con precisión el lugar en el que van a quedar posicionados los vértices determinantes de las aristas de la columna o pilar, los citados cuerpos anulares (7) presentarán sobre su superficie marcas (8), a modo de prolongación de los bordes internos de dicho anillo, las cuales se extienden hasta el borde externo del mismo, facilitando dicha identificación.In order to allow to identify easily and precisely the place where the determining vertices of the edges of the column or pillar will be positioned, the said annular bodies (7) will present marks (8) on their surface, as an extension of the inner edges of said ring, which extend to the outer edge thereof, facilitating said identification.
Cabe destacar igualmente que, como es convencional en este tipo de encofrados, el mismo estará dotado o no de medios de rasgado para eliminación del mismo cuando la columna esté completamente acabada. De acuerdo con un segundo ejemplo de realización práctica de la invención, el mostrado en la figura 6, a fin de reducir costes de fabricación, se ha previsto que el cuerpo anular (7) pueda dividirse en dos elementos en forma de "L", fijables entre sí mediante cualquier medio convencional (9), tanto por sus extremos como a lo largo de sus ramas, en diferentes posiciones, como por ejemplo las mostradas en dicha figura 6, en orden a que dicho conjunto pueda ser utilizado para adaptarse a encofrados de diferentes tamaños, de manera que, en cualquier caso, mediante la fijación de dichos elementos en "L", se obtendrá igualmente un marco anular de sección adecuada a la del encofrado de que se trate, sobre la que podrán igualmente plegarse y fijarse las aletas (6) de dicho encofrado. It should also be noted that, as is conventional in this type of formwork, it will be equipped or not with tearing means to eliminate it when the column is completely finished. According to a second example of practical embodiment of the invention, the one shown in Figure 6, in order to reduce manufacturing costs, it is provided that the annular body (7) can be divided into two "L" shaped elements, fixed to each other by any conventional means (9), both at its ends and along its branches, in different positions, such as those shown in said figure 6, in order that said assembly can be used to adapt to formwork of different sizes, so that, in any case, by fixing said elements in "L", an annular frame of suitable section to that of the formwork in question will also be obtained, on which they can also be folded and fixed. fins (6) of said formwork.
