Abstract

It is disclosed a flexible, inextensible, tubular body (1) made of a compact or woven material like, for example, paper or raffia, so that said tubular body can be modularly compacted or wound in rolls (2) during storage and transport. When the form work is assembled, cylindrical, rigid rings (3, 3') are coupled to the ends of the tubular body (1) and tightened to the ends of the tubular body (1) so that they remain definitely fixed by means of cramps or any other suitable element (4). Finally, the rings (3, 3') are conveniently separate by means of extensible poles (6) so that the complete tubular body (1) takes a cylindrical form. Thus, a structurally simple and inexpensive form work is obtained, which is easy to assemble, and in which the most expensive parts are recoverable and reusable.

Description

Encofrado para columnas cilíndricas.Formwork for cylindrical columns.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un encofrado que ha sido específicamente concebido para la obtención de columnas o pilares cilíndricos.The present invention relates to a formwork which has been specifically designed to obtain columns or cylindrical pillars.

El objeto de la invención es conseguir un encofrado estructuralmente muy simple y consecuentemente muy económico, que además suponga una ocupación volumétrica mínima en situación inoperante, es decir en situación de almacenaje y transporte, con la consecuente repercusión económica que esto trae también consigo.The object of the invention is to achieve a structural formwork very simple and consequently very economic, that also supposes a minimum volumetric occupation in inoperative situation, that is to say in storage situation and transport, with the consequent economic impact that this brings I also get.

La invención se sitúa pues en el ámbito de la construcción.The invention thus falls within the scope of the building.

Antecedentes de la invenciónBackground of the invention

Convencionalmente para la obtención de columnas cilíndricas, se utilizan encofrados a base de chapas modulares, semicilíndricas, que se fijan entre sí tanto lateral como longitudinalmente para configurar un cuerpo cilíndrico de diámetro y longitud apropiados a la columna a obtener. Esta solución presenta como ventaja fundamental el hecho de que el encofrado es recuperable/reutilizable, pero en contrapartida resulta extraordinariamente pesado y requiere de una gran participación de mano de obra tanto para su montaje como para su desmontaje y limpieza, a lo que hay que añadir además que los golpes a los que dichos módulos se ven normalmente sometidos generan en los mismos deformaciones que repercuten negativamente en el acabado de la columna.Conventionally to obtain columns cylindrical, formwork based on modular plates are used, semi-cylindrical, which fix each other both laterally and longitudinally to configure a cylindrical body of diameter and length appropriate to the column to be obtained. This solution presents as a fundamental advantage the fact that the formwork is recoverable / reusable, but in return it is extraordinarily heavy and requires a large participation of labor for both assembly and disassembly and cleaning, to which we must add in addition to the blows to which these modules are normally submitted generate in them deformations that have a negative impact on the finish of the column.

Tratando de obviar este problema se vienen utilizando desde hace tiempo encofrados para columnas cilíndricas consistentes en un cuerpo tubular y monopieza, por ejemplo estructurado a base de un estratificado de papel, aluminio y plástico, de suficiente rigidez como para asegurar una perfecta estabilidad de forma, de manera que con este tipo de encofrados se consigue un perfecto acabado formal y superficial para la columna, a expensas de dos problemas distintos y complementarios, por un lado una volumetría considerablemente mayor que con la solución anteriormente citada, que complica su almacenaje y transporte, y por otro lado un notable encarecimiento de costos, derivados fundamentalmente de su carácter monouso ya que el encofrado debe ser destruido para poder ser desacoplado de la columna ya fabricada.Trying to ignore this problem they come using formwork for cylindrical columns for a long time consisting of a tubular and single piece body, for example structured based on a laminate of paper, aluminum and plastic, of sufficient rigidity to ensure a perfect shape stability, so that with this type of formwork you get a perfect formal and superficial finish for the column, to  at the expense of two different and complementary problems, on the one hand a considerably larger volumetry than with the solution previously cited, which complicates its storage and transport, and on the other hand a notable increase in costs, derivatives fundamentally of its monouso character since the formwork must be destroyed to be decoupled from the spine already manufactured

Descripción de la invenciónDescription of the invention

El encofrado para columnas cilíndricas que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que elimina los problemas de cualquiera de las dos soluciones convencionales anteriormente citadas, a la vez que reúne sus prestaciones.The formwork for cylindrical columns that the proposed invention resolves in a fully satisfactory way the problematic previously exposed, so that it eliminates the problems of any of the two conventional solutions previously mentioned, at the same time that it gathers its benefits.

Para ello y de forma más concreta el encofrado que se preconiza está constituido a partir de un cuerpo tubular flexible e inextensible, como por ejemplo a base de un material tejido de naturaleza vegetal, mineral o sintético, pudiéndose igualmente compacto, como papel, polímero,..., en forma laminar. Cuerpo que por su propia naturaleza se puede almacenar y transportar aplastado de forma modular o arrollado en forma de bobina, lo que permite que el encofrado correspondiente a una columna de considerables diámetro y altura, pueda mantenerse, mientras resulta inoperante, con una ocupación volumétrica mínima, muy inferior a la de los sistemas a base de chapas modulares, y muchísimo inferior aún que los sistemas de tubo rígido.For this and more specifically the formwork which is recommended is constituted from a tubular body flexible and inextensible, such as based on a material plant, mineral or synthetic tissue, being able to equally compact, such as paper, polymer, ..., in laminar form. Body that by its very nature can be stored and transport crushed modularly or rolled in the form of coil, which allows the formwork corresponding to a column of considerable diameter and height, can be maintained, while it is inoperative, with minimal volumetric occupancy, much lower than that of systems based on modular plates, and much lower than rigid tube systems.

El citado cuerpo tubular se complementa con una pareja de anillos cilíndricos rígidos, destinados a acoplarse en los extremos del cuerpo tubular, para que tales extremos adopten una configuración perfectamente cilíndrica, fijándose tales anillos mediante grapas o por cualquier otro medio apropiado.The said tubular body is complemented by a pair of rigid cylindrical rings, intended to engage in the ends of the tubular body, so that such ends adopt a perfectly cylindrical configuration, fixing such rings by staples or by any other appropriate means.

La estructura descrita se complementa con un grupo de pértigas extensibles, en número no inferior a dos, acoplables por sus extremos en los elementos de enganche o acople operativamente establecidos en los citados anillos, de manera que un adecuado tensado y fijación de las citadas pértigas originan que el cuerpo tubular adopte una configuración cilíndrica en toda su extensión, y que además se mantenga perfectamente estable durante el proceso del hormigonado.The structure described is complemented by a group of extensible poles, in number not less than two, attachable at its ends in the coupling or coupling elements operatively established in the aforementioned rings, so that an adequate tension and fixation of the mentioned poles originate that the tubular body adopts a cylindrical configuration in all its extension, and also remain perfectly stable during the  concreting process.

Evidentemente las citadas pértigas son recuperables tras el fraguado del hormigón el cuerpo tubular es eliminable mediante cortes longitudinales del mismo, constituyendo un único elemento desechable.Obviously the mentioned poles are Recoverable after setting the concrete the tubular body is removable by longitudinal cuts thereof, constituting A single disposable item.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como el encofrado que se preconiza está constituido a partir de un cuerpo tubular (1) de un material flexible e inextensible, por ejemplo un material tejido para conseguir una perfecta estabilidad dimensional tanto en sentido longitudinal como en sentido radial, tal como tejido de rafia, láminas de papel o polímeros, de manera que dicho cuerpo tubular (1) es susceptible de aplastarse sobre sí mismo de forma modular o de arrollarse formando una bobina (2), tal como se observa en la figura 1, para minimizar su ocupación volumétrica. Lógicamente la anchura de la banda constituida por el cuerpo tubular (1) será la adecuada al diámetro previsto para la columna, por lo que se deberá disponer de cuerpos tubulares de diferentes dimensiones para distintas aplicaciones al efecto, y la longitud puede a su vez estar modulada de acuerdo con alturas preestablecidas para las columnas, o bien la bobina (2) puede presentar una longitud indefinida, pudiendo extraerse de la misma, mediante corte, diversos fragmentos correspondientes a respectivas columnas o encofrados.In view of the figures outlined you can observe how the formwork that is recommended is constituted to from a tubular body (1) of a flexible material e inextensible, for example a woven material to achieve a perfect dimensional stability both longitudinally and radially, such as raffia tissue, sheets of paper or polymers, so that said tubular body (1) is susceptible to crush on itself in a modular way or roll over forming a coil (2), as seen in figure 1, to minimize its volumetric occupation. Logically the width of the band constituted by the tubular body (1) will be adequate to the diameter provided for the column, so bodies must be available tubular of different dimensions for different applications at effect, and the length may in turn be modulated according to preset heights for the columns, or the coil (2) it can have an indefinite length, being able to be extracted from the same, by cutting, various fragments corresponding to respective columns or formwork.

Con el cuerpo tubular (1), y más concretamente con el segmento del mismo correspondiente a un encofrado o columna, colaboran una pareja de anillos rígidos y cilíndricos (3-3'), destinados a acoplarse ajustadamente en el cuerpo tubular (1), en los extremos del mismo, como se observa especialmente en la sección de la figura 3, pudiendo estos anillos (3-3') ser de plástico duro o de cualquier otro material apropiado, y fijándose al cuerpo tubular (1) mediante grapas (4) o similar.With the tubular body (1), and more specifically with the segment thereof corresponding to a formwork or column, a couple of rigid and cylindrical rings collaborate (3-3 '), intended to fit tightly in the tubular body (1), at the ends thereof, as observed especially in the section of figure 3, these rings being able (3-3 ') be hard plastic or any other appropriate material, and fixing to the tubular body (1) by staples (4) or similar.

Evidentemente estas pértigas extensibles (6) son recuperables y reutilizables.Going back to the rings (3-3 ') these have coupling elements or coupling (5) in its mouth in mounting position on the body tubular (1), these hooks (5) having the purpose of constitute means of support for the ends of respective poles  extendable (6), each of which is telescopic, to be able to adapt its dimensions to any column or formwork height, and also have tightening and locking means (7) that allow in turn establish an adequate tension tending to the separation of the rings (3-3 ') and, consequently, a suitable tension in the tubular body (1), as shown in Figure 2, so that it adopts a perfectly cylindrical configuration in All its extension. Obviously these extensible poles (6) are Recoverable and reusable.

Cabe señalar por último que, en función de las exigencias específicas de cada caso, y más concretamente en función del acabado superficial requerido para la columna, el cuerpo tubular y textil o compacto (1) puede incorporar una lámina interior de revestimiento integral, no representada en los dibujos, de cualquier material apropiado para que la superficie de la columna a obtener resulte perfectamente lisa o adopte cualquier tipo de irregularidad superficial, por ejemplo imitando las betas de la madera.Finally, it should be noted that, depending on the specific requirements of each case, and more specifically in function of the surface finish required for the column, the body tubular and textile or compact (1) can incorporate a sheet integral lining interior, not shown in the drawings, of any appropriate material so that the surface of the column to get perfectly smooth or adopt any kind of superficial irregularity, for example imitating the betas of  timber.
