Encofrado plegable para columnas prismáticas.Column formwork binoculars
La presente invención se refiere a un encofrado de los utilizados en la construcción "in situ" de columnas prismáticas, ya sean de sección cuadrangular, de sección básicamente cuadrangular y vértices truncados, o con cualquier otra sección poligonal, encofrados esencialmente no recuperables, es decir, mono-uso, que son eliminados en el momento del desencofrado de las columnas.The present invention relates to a formwork used in the construction " in situ " of prismatic columns, whether of quadrangular section, basically quadrangular section and truncated vertices, or with any other polygonal section, essentially non-recoverable formwork, that is , mono-use, which are eliminated at the time of decoupling the columns.
El objeto de la invención es conseguir que, además de la reducción volumétrica derivada del carácter plegable del encofrado, se potencie aún más dicha reducción volumétrica merced a las características de la envolvente que da resistencia a dicho encofrado, eliminando además cualquier manipulación final por parte del constructor, que no sea la de la simple implantación del encofrado en el lugar de obtención de la columna.The object of the invention is to achieve that, in addition to the volumetric reduction derived from the folding character formwork, further enhance this volumetric reduction thanks to the characteristics of the envelope that gives resistance to said formwork, also eliminating any final manipulation by part of the constructor, other than the simple implementation of the formwork at the place of obtaining the column.
El propio solicitante es titular de la patente de invención con número de solicitud P 200400436, consistente en un encofrado para columnas prismáticas del tipo de las que incorporan un núcleo tubular, determinante de un alojamiento interior prismático, como por ejemplo prismático cuadrangular, prismático hexagonal, etc, y de una superficie exterior cilíndrica, a base de la utilización de piezas en forma de segmento cilíndrico, relacionadas interiormente entre sí mediante un revestimiento impermeable y tubular, que además de determinar una superficie totalmente continua para el encofrado, y consecuentemente una superficie también continua y uniforme para la columna a obtener, permite el plegado del encofrado en situación inoperante, para minimizar su ocupación volumétrica cuando se encuentra almacenado o en fase de transporte.The applicant himself owns the patent of invention with application number P 200400436, consisting of a formwork for prismatic columns of the type they incorporate a tubular core, determinant of an inner housing prismatic, such as quadrangular prismatic, prismatic hexagonal, etc., and of a cylindrical outer surface, based on the use of parts in the form of a cylindrical segment, internally related to each other by a coating waterproof and tubular, which in addition to determining a surface totally continuous for the formwork, and consequently a surface also continuous and uniform for the column to be obtained, allows the folding of the formwork in an inoperative situation, to minimize its volumetric occupancy when stored or in transport phase.
El citado núcleo tubular se complementa con una funda exterior, que dota al núcleo de la citada rigidez, de manera que dicha funda puede materializarse en un cuerpo cilíndrico semirrígido, con un corte en correspondencia con una de sus generatrices, que permite su montaje sobre el núcleo tubular, de manera que tras dicho montaje la funda exterior se mantiene debidamente rigidizada y ceñida sobre el núcleo mediante una cincha o fleje mediante aros dotados de cierres de presión o mediante cualquier otro tipo de elemento anular capaz de mantener la funda debidamente cerrada.The said tubular core is complemented by a outer sheath, which gives the core of said stiffness, so that said sheath can materialize in a cylindrical body semi-rigid, with a cut corresponding to one of its generatrices, which allows mounting on the tubular core, of so that after said assembly the outer case is maintained duly stiffened and tight on the core by means of a webbing or strapping by means of rings fitted with pressure closures or by any other type of annular element capable of maintaining the sheath properly closed.
También se preveía en dicha patente de invención la utilización como envolvente para dar rigidez al encofrado de dos piezas laminares semicilíndricas, como por ejemplo dos chapas de acero, abisagradas por uno de sus bordes y dotadas de medios de cierre en el borde opuesto, dentro de una también amplia gama de posibilidades al respecto.It was also provided in said invention patent the use as envelope to give rigidity to the formwork of two semi-cylindrical sheet pieces, such as two sheets of steel, hinged by one of its edges and equipped with means of closure on the opposite edge, within a wide range of possibilities about it.
Esta solución, si bien supone un avance tecnológico frente al anterior Estado de la Técnica, presenta sin embargo dos aspectos relativamente negativos, que van a ser solventados con el objeto de la presente invención.This solution, although it represents an advance technological compared to the previous State of the Art, presents without however two relatively negative aspects, which are going to be Solved for the purpose of the present invention.
Uno de ellos es la propia volumetría de la funda envolvente, y el otro las manipulaciones y el tiempo necesario para introducir el núcleo tubular en la funda, cerrar y estabilizar a esta última.One of them is the case's own volumetry envelope, and the other manipulations and the time needed to insert the tubular core into the sheath, close and stabilize this last.
El encofrado que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los dos aspectos comentados.The formwork that the invention proposes resolves in a fully satisfactory way the problem previously exposed, in the two aspects commented.
Para ello y de forma más concreta el encofrado de la invención, con un núcleo estructurado como en la patente de invención P 200400436 anteriormente citada, es decir un núcleo tubular a base de piezas de material ligero, como por ejemplo de poliestireno expandido, en forma de segmento cilíndrico, unidas entre sí mediante un revestimiento interior estanco y continuo, es decir de forma tubular, que permita la plegabilidad del núcleo y que además asegure una perfecta continuidad superficial tanto en el propio núcleo como en la columna a obtener, al invención se centra en el hecho de que como envolvente estabilizadora del citado núcleo, el encofrado incorpora una envolvente consistente en una lámina o malla de naturaleza vegetal, mineral o sintético, que confiere al núcleo tubular la adecuada resistencia estructural en situación de trabajo, pero con la que se consiguen dos efectos beneficiosos para la manipulación del encofrado, en primer lugar la inexistencia de la clásica envolvente exterior semirrígida y desmontable, que requiere de las citadas operaciones de montaje, cierre y fijación en obra, y por otro lado que la envolvente a base de una lámina o malla permita el plegado del núcleo al que está asociada, de manera que la repercusión de dicha envolvente desde el punto de vista de ocupación volumétrica en fase de almacenaje y transporte del encofrado es prácticamente nula.For this and more specifically the formwork of the invention, with a structured core as in the patent of invention P 200400436 cited above, ie a core tubular based on lightweight pieces of material, such as expanded polystyrene, cylindrical segment shaped, joined each other by a watertight and continuous inner lining, it is say in a tubular way, which allows the folding of the core and that also ensures perfect surface continuity both in the own core as in the column to be obtained, the invention is centered in the fact that as a stabilizing envelope of the aforementioned core, the formwork incorporates an envelope consisting of a sheet or mesh of a vegetable, mineral or synthetic nature, which gives the tubular core the appropriate structural resistance in work situation, but with which two effects are achieved beneficial for formwork manipulation, first of all the nonexistence of the classic semi-rigid outer shell and detachable, which requires the aforementioned assembly operations, closing and fixing on site, and on the other hand that the base envelope of a sheet or mesh allow the folding of the core to which it is associated, so that the impact of said envelope from the point of view of volumetric occupancy in the storage phase and Formwork transport is virtually nil.
La citada envolvente exterior plegable y resistente estará debidamente adherida al resto de la estructura del encofrado, mediante pegamento, termosoldadura o por cualquier otro medio adecuado al tipo de materiales utilizados.The aforementioned folding outer envelope and resistant will be properly adhered to the rest of the structure formwork, by glue, heat welding or by any other means appropriate to the type of materials used.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:
La figura 1.- Muestra un detalle en sección transversal de un encofrado plegable para columnas prismáticas realizado de acuerdo con el objeto de la presente invención, en situación de trabajo y con un sector ampliado para mostrar con mayor claridad su estructura.Figure 1.- Shows a detail in section cross section of a folding formwork for prismatic columns carried out in accordance with the object of the present invention, in working situation and with an expanded sector to show with more clarity its structure.
La figura 2.- Muestra, según una vista en perspectiva, el conjunto de la figura anterior debidamente plegado, en situación de almacenaje y transporte, también con un detalle ampliado.Figure 2.- Shows, according to a view in perspective, the whole of the previous figure duly folded, in storage and transport situation, also with a detail extended.
A la vista de las figuras reseñadas puede observarse como el encofrado plegable para columnas prismáticas que la invención propone está constituido, como un encofrado convencional de este tipo, a partir de un núcleo tubular (1) que define interiormente un alojamiento prismático (2), en el ejemplo de realización práctica elegido prismático-cuadrangular, con chaflanes (3) en sus aristas, pero que puede adoptar cualquier otra configuración prismático-poligonal, materializándose dicho núcleo (1) en una pluralidad de segmentos cilíndricos (4), de poliuretano expandido u otro material ligero similar, con un revestimiento interior (5) estanco, concretamente un cuerpo tubular de naturaleza plástica, que actúa como bisagra para los segmentos cilíndricos (5), tanto en el caso de existir los citados chaflanes (3) del ejemplo de realización práctica representado en las figuras, como cuando dichos chaflanes no existen.In view of the figures outlined you can be seen as the folding formwork for prismatic columns that The proposed invention is constituted, as a formwork conventional of this type, from a tubular core (1) that internally defines a prismatic housing (2), in the example of practical implementation chosen prismatic-quadrangular, with chamfers (3) in their edges, but you can adopt any other configuration prismatic-polygonal, said core materializing (1) in a plurality of cylindrical segments (4), of polyurethane expanded or other similar lightweight material, with a coating watertight interior (5), specifically a tubular body of nature plastic, which acts as a hinge for cylindrical segments (5), both in the case of the aforementioned chamfers (3) of the example of practical embodiment represented in the figures, such as when these chamfers do not exist.
Pues bien, de acuerdo ya con la invención al citado núcleo (l) está debidamente fijada una envolvente exterior (6), materializa preferentemente en una lámina o malla, flexible y de alta resistencia mecánica, arrollada sobre el resto del núcleo tubular (1) y fijada al mismo, a su vez preferentemente mediante adhesivo, al igual que el revestimiento tubular e interior estanco (5), de manera que el envolvente además de estabilizar mecánicamente el núcleo tubular (1), permite el plegamiento de dicho núcleo sobre sí mismo, tal como muestra la figura 2.Well, according to the invention at said core (l) an outer envelope is properly fixed (6), preferably materialized in a sheet or mesh, flexible and high mechanical resistance, rolled over the rest of the core tubular (1) and fixed thereto, in turn preferably by adhesive, as well as the watertight inner and tubular lining (5), so that the envelope in addition to stabilizing mechanically the tubular core (1), allows the folding of said core on itself, as shown in figure 2.
Así pues, el citado envolvente exterior (6) sustituye a la clásica funda de material semirrígido y abierta, lo que supone la eliminación de todos los problemas inherentes a esta última, como son su ocupación de espacio y las manipulaciones necesarias para su montaje.Thus, the aforementioned outer envelope (6) replaces the classic case of semi-rigid and open material, what that supposes the elimination of all the problems inherent to this last, as are their occupation of space and manipulations necessary for assembly.
La flexibilidad de la envolvente exterior (6), determinada por su propia naturaleza y necesaria para el plegamiento del encofrado durante su almacenaje y transporte, no supone problema alguno durante su utilización, ya que evidentemente el peso del hormigón alojado en su interior generará un esfuerzo tendente a que la volumetría del alojamiento (2) sea máxima, y consecuentemente esto tan sólo se consigue cuando dicha envolvente (6) adopta la configuración cilíndrica, que a su vez determina que dicho alojamiento (2) resulte perfectamente prismático, de acuerdo con la configuración prevista para el mismo.The flexibility of the outer shell (6), determined by its own nature and necessary for the formwork folding during storage and transport, not It is a problem during its use, since obviously the weight of the concrete housed inside will generate an effort tending to the maximum volumetry of the housing (2), and consequently this is only achieved when said envelope (6) adopts the cylindrical configuration, which in turn determines that said housing (2) is perfectly prismatic, according with the configuration planned for it.
