Más concretamente, en todas esas patentes de invención del mismo solicitante, el encofrado está basado en utilizar piezas en forma de segmento cilindrico, que debidamente montadas dan lugar a una superficie exterior cilindrica y una superficie interior prismática, o bien con la conformación apropiada de acuerdo con las características de la columna a obtener, presentando como denominador común en todos los casos el hecho de que el encofrado sale acabado de fábrica, es decir formando un cuerpo tubular que indudablemente ocupa un gran volumen con los consiguientes problemas de almacenaje y de transporte y, por supuesto, con el encarecimiento debido a esa elevada volumetría.More specifically, in all those invention patents of the same applicant, the formwork is based on using pieces in the form of a cylindrical segment, which duly assembled give rise to a cylindrical outer surface and a prismatic inner surface, or with the appropriate conformation according to with the characteristics of the column to be obtained, presenting as a common denominator in all cases the fact that the formwork is finished at the factory, that is, forming a tubular body that undoubtedly occupies a large volume with the consequent storage and transport problems and , of course, with the increase due to this high volume.
Por otro lado, cabe decir que los encofrados utilizados en las comentadas patentes de invención únicamente se pueden utilizar una vez, ya que hay que romper el encofrado para liberar la columna que se ha obtenido con el mismo.On the other hand, it should be said that the formwork used in the mentioned invention patents can only be used once, since the formwork must be broken to release the column that has been obtained therewith.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El encofrado reutilizable que se preconiza, ha sido concebido para resolver la problemática anteriormente expuesta, en base a una solución sencilla pero de gran eficacia, basándose en que las piezas de poliestireno que han de conformar el cuerpo tubular del encofrado, se fijan mediante adhesivo
a una lámina interior que puede ser de plástico termo-conformado, acero galvanizado o inoxidable perfilado, etc, la cual presentará las oportunas líneas longitudinales de debilitamiento para formar las aristas o líneas de doblez cuando se intente cerrar el conjunto de esa lámina con las piezas de poliestireno y conseguir el encofrado tubular correspondiente, con la particularidad de que en el caso de obtener un encofrado cilindrico, entonces no se necesitan las líneas de debilitamiento que determinen las dobleces referidas.The reusable formwork that is recommended, has been designed to solve the above-mentioned problem, based on a simple but highly effective solution, based on the polystyrene pieces that are to form the tubular formwork body, are fixed by adhesive to an inner sheet that can be made of thermoformed plastic, galvanized steel or profiled stainless steel, etc., which will present the appropriate longitudinal lines of weakness to form the edges or fold lines when trying to close the assembly of that sheet with the pieces of polystyrene and to obtain the corresponding tubular formwork, with the particularity that in the case of obtaining a cylindrical formwork, then the weakening lines that determine the referred bends are not needed.
La lámina interior presenta a intervalos regulares, que corresponde a la anchura de las piezas de poliestireno, unos quiebros para ajuste de las conformaciones que determinan las uniones colaterales de las piezas de poliestireno, en cuyos quiebros es donde se materializan las líneas debilitadas para el centrado del encofrado.The inner sheet has, at regular intervals, corresponding to the width of the polystyrene pieces, some breaks to adjust the conformations that determine the collateral joints of the polystyrene pieces, whose breaks are where the weakened lines for centering materialize of the formwork.
En cualquier caso, la lámina interior sobre la que van fijadas por pegado las piezas de poliestireno, forman un conjunto o cuerpo único plano que puede almacenarse y transportarse con facilidad, ocupando un volumen mucho menor que si el encofrado está cerrado, es decir formando ya el cuerpo tubular, en virtud de verse reducidos considerablemente los espacios muertos.In any case, the inner sheet on which the polystyrene pieces are fixed by glue, form a single flat assembly or body that can be easily stored and transported, occupying a much smaller volume than if the formwork is closed, that is, already forming the tubular body, by virtue of considerably reducing dead spaces.
Cada encofrado en su desarrollo se cerrará en obra para transformar el cuerpo plano en un cuerpo tubular, realizándose el cierre mediante una precinto autoadhesivo formado por un soporte de papel o similar que incorpora unos hilos de fibra de vidrio para resistir la presión del hormigón fresco cuando se deposita en el interior del cuerpo tubular del encofrado, con la especial particularidad de que este precinto autoadhesivo se aplica externamente, a través de una capa de cola autoadhesiva que incorpora, sobre el cuerpo tubular, mediante una máquina apropiada,
quedando el encofrado listo para su uso, para que una vez utilizado se corte el encofrado por el borde del cierre, que estará debidamente señalizado, procediéndose a su limpieza, a la retirada del precinto autoadhesivo y a cerrarse de nuevo mediante otro precinto autoadhesivo nuevo para la posterior utilización del encofrado.Each formwork in its development will be closed on site to transform the flat body into a tubular body, the closure being made by a self-adhesive seal formed by a paper support or similar that incorporates fiberglass threads to resist the pressure of fresh concrete when it is deposited inside the tubular formwork body, with the special feature that this self-adhesive seal is applied externally, through a layer of self-adhesive glue that incorporates, on the tubular body, by an appropriate machine, the formwork being ready for use, so that once the formwork is cut, the edge of the closure will be cut, which will be properly marked, proceeding to its cleaning, the removal of the self-adhesive seal and to be closed again by means of another new self-adhesive seal for the subsequent use of formwork.
Por otra parte, cabe destacar el hecho de que en los extremos del propio encofrado, y en correspondencia con las propias aristas de la columna a obtener, se establecen pequeñas piezas de cartón o plástico como medios señalizadores o de alineación que facilitan el correcto posicionamiento del encofrado sobre la cimentación.On the other hand, it is worth noting the fact that at the ends of the formwork itself, and in correspondence with the very edges of the column to be obtained, small pieces of cardboard or plastic are established as signaling or alignment means that facilitate the correct positioning of the formwork on the foundation.
La máquina para la fabricación del encofrado descrito, se constituye a partir de un bastidor de soporte sobre el que va dispuesto un rodillos superior accionado en giro mediante un motor, rodillo que se complementa con una pareja de ruedas laterales y distanciadas de aquel para constituir un apoyo para el cuerpo tubular de poliestireno, de manera que el giro del motor lleva consigo el giro del rodillo y por lo tanto el giro del cuerpo tubular, para permitir la aplicación por enrollamiento del precinto autoadhesivo.The machine for the manufacture of the formwork described, is constituted from a support frame on which an upper rollers driven by a motor are arranged, a roller that is complemented by a pair of lateral wheels and distanced from it to constitute a support for the tubular polystyrene body, so that the rotation of the motor entails the rotation of the roller and therefore the rotation of the tubular body, to allow the self-adhesive seal to be rolled up.
Opcionalmente, el accionamiento del cuerpo tubular puede efectuarse manualmente, en cuyo caso se eliminaría el motor, y el comentado rodillo sería sustituido por una pareja de ruedas enfrentadas lateralmente a las otras dos ruedas extremas.Optionally, the actuation of the tubular body can be carried out manually, in which case the motor would be eliminated, and the said roller would be replaced by a pair of wheels facing laterally to the other two extreme wheels.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como el encofrado de la invención se constituye a partir de una lámina interior (1), de
desarrollo rectangular, que puede ser de plástico, acero u otro material apropiado, sobre la que se fijan mediante pegado piezas de poliestireno (2) formando un cuerpo plano como se representa en la figura 1, que es el desarrollo del cuerpo del encofrado a obtener mediante el cierre de este cuerpo de dicha figura 1, ya que cerrándose a través de los bordes libres se obtiene el cuerpo tubular (3) constitutivo del encofrado propiamente dicho, que en la forma de realización representada es de superficie externa cilindrica y superficie interna prismática, sin descartar que pueda ser también cilindrica por el interior.In view of the figures outlined, it can be seen how the formwork of the invention is constituted from an inner sheet (1), of rectangular development, which can be of plastic, steel or other appropriate material, on which polystyrene pieces (2) are fixed by gluing forming a flat body as shown in figure 1, which is the development of the formwork body to be obtained by closing this body of said figure 1, since by closing through the free edges the tubular body (3) constituting the formwork itself is obtained, which in the embodiment represented is of cylindrical external surface and prismatic internal surface , without ruling out that it can also be cylindrical inside.
En cualquier caso, si ese cuerpo va a ser de configuración prismática por el interior, entonces la lámina interior (1) presentará una serie de líneas de doblez debilitadas (I5) para permitir el doblado a través de ellas y conformar el cuerpo tubular (3) de configuración prismática rectangular, como se representa en la figura 2.In any case, if that body is going to be of prismatic configuration on the inside, then the inner sheet (1) will present a series of weakened fold lines (I 5 ) to allow bending through them and form the tubular body ( 3) of rectangular prismatic configuration, as shown in Figure 2.
Concretamente, las líneas de debilitamiento (1') corresponden a las aristas de respectivos quiebros (5) previstos en la lámina (1), cuya separación se corresponderá con la anchura de las piezas de poliestireno (2), estando éstas unidas entre sí determinando conformaciones (6) que en el plegado o cierre se adaptaron a la forma de los quiebros (5) de la lámina (1).Specifically, the weakening lines (1 ') correspond to the edges of respective breaks (5) provided in the sheet (1), whose separation will correspond to the width of the polystyrene pieces (2), these being joined together determining conformations (6) that in the folding or closing were adapted to the shape of the breaks (5) of the sheet (1).
En correspondencia con la línea que determina el cierre del comentado cuerpo tubular, se aplica un elemento señalizador a través del cual se llevará a cabo la posterior apertura del encofrado por seccionado a través de esa línea de unión, permitiendo la utilización del encofrado.In correspondence with the line that determines the closure of the said tubular body, a signaling element is applied through which the subsequent opening of the formwork will be carried out by sectioning through that joining line, allowing the use of the formwork.
Cabe destacar el hecho de que el cierre del cuerpo tubular (3), para soportar la presión hacia el exterior del hormigón que ha de alojarse en el cuerpo (3') del mismo para conformar la columna correspondiente, se
realiza mediante la aplicación exterior de un precinto autoadhesivo que puede ir arrollado helicoidalmente, con la particularidad de que este precinto podrá estar formado por un soporte de papel o similar con una capa de cola auto- adhesiva en una de sus caras y en cuyo seno pueden ir embebidos hilos de fibra de vidrio, al objeto de soportar la presión del hormigón fresco cuando se introduce en el hueco (3') del cuerpo tubular (3) del encofrado.It should be noted that the closure of the tubular body (3), to withstand the outward pressure of the concrete to be housed in the body (3 ') thereof to form the corresponding column, is made by means of the external application of a self-adhesive seal that can be wound helically, with the particularity that this seal may be formed by a paper support or the like with a layer of self-adhesive glue on one of its faces and in which they can go embedded fiberglass threads, in order to withstand the pressure of the fresh concrete when it is introduced into the hollow (3 ') of the tubular body (3) of the formwork.
En correspondencia con las aristas de la columna a obtener, se aplican pequeñas piezas de cartón o plástico (4) determinantes de medios de señalización, que facilitan el correcto posicionamiento del encofrado sobre la cimentación (8).In correspondence with the edges of the column to be obtained, small pieces of cardboard or plastic (4) determining signaling means are applied, which facilitate the correct positioning of the formwork on the foundation (8).
Después de obtener la columna mediante el encofrado descrito y representado en la figura 2, se procede al seccionado de éste a través de la línea de unión anteriormente referida, debidamente señalizada, desplegándose de nuevo el cuerpo que forman la lámina interior (1) y las piezas de poliestireno (2), de manera que llevándose a efecto una limpieza interna y volviendo a cerrar de nuevo el encofrado, mediante la aplicación de nuevo del precinto autoadhesivo, previa retirada del anterior, se consigue un encofrado para su nueva utilización, es decir, que el encofrado de la invención es reutilizable tantas veces como se desee sin más que ir cerrándole y aplicando el precinto autoadhesivo por la cara externa, abriéndole e ir cerrando de nuevo mediante la aplicación de un nuevo precinto autoadhesivo.After obtaining the column by means of the formwork described and represented in Figure 2, the sectioning is carried out through the previously mentioned connection line, duly signposted, the body forming the inner sheet (1) and polystyrene pieces (2), so that an internal cleaning is carried out and the formwork is closed again, by applying the self-adhesive seal again, after removing the previous one, a formwork is achieved for its new use, that is to say , that the formwork of the invention is reusable as many times as desired by simply closing and applying the self-adhesive seal on the external face, opening and closing again by applying a new self-adhesive seal.
En la reutilización del encofrado interviene el uso de una máquinaThe use of a machine is involved in the reuse of the formwork
(7) mediante la que se aplica una capa de film estirable que permite la retirada del precinto autoadhesivo en cada reutilización. Con esta misma máquina se aplica también el precinto autoadhesivo para volver a cerrar el encofrado. Para ello, la máquina (7) se constituye a partir de un bastidor o bancada sobre a que va dispuesto un rodillo superior (9), horizontal, entre el
cual y una pareja de ruedas extremas (10) y distantes de aquél, apoya el cuerpo tubular (3) del encofrado. La máquina incluye un motor (11) de accionamiento del rodillo (9) para que el giro de éste lleve consigo el giro del cuerpo tubular (3), permitiendo la aplicación por enrollamiento del precinto autoadhesivo.
(7) by means of which a layer of stretch film is applied that allows the self-adhesive seal to be removed at each reuse. With this same machine, the self-adhesive seal is applied to close the formwork again. For this, the machine (7) is constituted from a frame or bench on which a top roller (9) is arranged, horizontal, between the which and a pair of extreme wheels (10) and distant from it, supports the tubular body (3) of the formwork. The machine includes a motor (11) for driving the roller (9) so that the rotation of the roller carries with it the rotation of the tubular body (3), allowing the application by winding of the self-adhesive seal.
