Las figuras 4a, 4b y 4c.- Muestran sendas vistas en planta de la pieza interior que participa en el encofrado de las figuras anteriores, correspondientes a su fase de plegado.Figures 4a, 4b and 4c.- They show paths in plan of the inner piece that participates in the formwork of the previous figures, corresponding to its folding phase.
A la vista de las figuras reseñadas puede observarse como el encofrado plegable que la invención propone está constituido a partir de una pieza exterior (1), la mostrada en detalle en las diferentes secuencias de la figura 3, y una pieza interior (2), la mostrada igualmente en las secuencias de la figura 4, pieza (2) destinada a insertarse en el seno de la pieza (1), para la formación de pilares de hormigón y materiales similares, tal y como se puede observar en las figuras 1 y 2.In view of the figures outlined you can be observed as the folding formwork that the invention proposes is constituted from an outer part (1), the one shown in detail in the different sequences of figure 3, and a piece interior (2), also shown in the sequences of the figure 4, part (2) intended to be inserted inside the part (1), for the formation of concrete pillars and similar materials, as can be seen in figures 1 and 2.
De forma más concreta, la pieza exterior (1), adopta en disposición de montaje una configuración prismático octogonal, con un vaciado interior (3), de configuración prismático cuadrangular, vaciado (3) que adopta una disposición en la que sus caras (4) son paralelas a caras (5) alternadas de la superficie prismático octogonal exterior de la pieza, con una amplitud tal que sus aristas se extienden hasta la zona media (6) de las caras restantes.More specifically, the outer part (1), adopts a prismatic configuration in mounting arrangement octagonal, with an internal drain (3), prismatic configuration quadrangular, emptied (3) that adopts a provision in which its faces (4) are parallel to alternating faces (5) of the surface Octagonal prismatic exterior of the piece, with an amplitude such that its edges extend to the middle zone (6) of the faces remaining.
La pieza exterior (1) está constituida a partir de una lámina exterior y envolvente de material plástico, que coincide con la propia referencia (5) y una lámina envolvente e interior de material también plástico, que se corresponde igualmente con la referencia (4), entre las que se establece, preferentemente adheridas a la misma, sendos núcleos (7) de poliestireno expandido que adoptan una configuración prismático trapecial.The outer part (1) is made from of an outer sheet and wrap of plastic material, which matches the reference itself (5) and a wrapping sheet e inner material also plastic, which corresponds also with reference (4), among which is established, preferably adhered thereto, two cores (7) of expanded polystyrene that adopt a prismatic configuration trapecial
Así pues, y tal y como se puede observar en las figuras 3a, 3b y 3c, la zona de confluencia (6) entre núcleos (7), merced a la existencia en la misma de la capa externa e interna de material plástico, determina los medios de abatimiento para elemento o pieza (1), el cual podrá ser fácilmente plegado en situación inoperante o de transporte, como muestra la figura 3c, para una ocupación volumétrica mínima.So, and as can be seen in the Figures 3a, 3b and 3c, the confluence zone (6) between cores (7), thanks to the existence in it of the external and internal layer of plastic material, determines the abatement means for element or piece (1), which can be easily folded into inoperative or transport situation, as shown in Figure 3c, for a minimum volumetric occupation.
De igual manera la pieza interior (2), está constituida a partir de cuatro planchas de contrachapado EPDM de reducido espesor, que en disposición de montaje configuran las caras mayores de un prisma cuadrangular, con sus aristas achaflanadas, las cuales se constituyen a partir de estrechas tiras (9) del mismo material, estando dichas piezas unidas articuladamente entre sí a través de una envolvente interior plástica (10) fijada mediante adhesivo a las mismas. Exteriormente a los chaflanes (9) se ha previsto la fijación de sendas piezas de poliestireno (11) de configuración prismático triangular isoscélicas en orden a que la pieza interna (2) encaje perfectamente en el seno del vaciado (3) de la pieza (1).In the same way the inner part (2), is constituted from four EPDM plywood sheets of reduced thickness, which in mounting arrangement configure the major faces of a quadrangular prism, with its edges chamfered, which are constituted from narrow strips (9) of the same material, said pieces being joined articulated with each other through an inner envelope plastic (10) fixed by adhesive to them. Externally to the chamfers (9) it is planned to fix two pieces of polystyrene (11) of triangular prismatic configuration isoscelics in order that the inner part (2) fits perfectly within the emptying (3) of the piece (1).
Así pues, merced a la capa interna (10) de material plástico de la pieza interior (2), ésta puede igualmente plegarse en situación inoperante de almacenamiento o transporte con una ocupación volumétrica mínima, tal como puede verse en la figura 4c.Thus, thanks to the inner layer (10) of plastic material of the inner part (2), it can also fold in inoperative storage or transport situation with a minimum volumetric occupation, as can be seen in the figure 4c.
Tal y como anteriormente se ha dicho, las piezas (1) y (2) se transportarán plegadas, de manera que en el instante de su implantación sobre el lugar a realizar el pilar o columna éstos se desplegarán, insertando uno en el seno del otro. No obstante el encofrado podrá servirse igualmente montado cuando el espacio disponible para su transporte lo permita.As previously stated, the pieces (1) and (2) will be transported folded, so that instantly of its implantation on the place to perform the pillar or column these will unfold, inserting one into the other. Do not However, the formwork can also be assembled when the space available for transportation allows.
Asimismo cabe destacar el hecho de que en
función de la longitud del pilar, se ha previsto la inclusión de un
determinado número anillos (12) de naturaleza metálica, de sección
octogonal y de dimensiones internas acordes con las dimensiones
externas de la pieza exterior (1), en orden a estabilizar el
encofrado.Also noteworthy is the fact that depending on the length of the pillar, it is planned to include a certain number of rings (12) of a metallic nature, octagonal section and internal dimensions in accordance with the external dimensions of the outer part (1 ), in order to stabilize the
formwork
Por último decir que, para el desmontaje del encofrado, una vez fraguado el hormigón vertido en su seno, éste será desechado una vez retirados los anillos (12), a través de una línea vertical (13) de desmontaje, que se corresponde con una de las aristas (6), de manera que mediante la retirada de una cinta adhesiva, un hilo de acero o cualquier otro elemento similar, se produzca la apertura del elemento tubular, pasando éste a tener una configuración abierta que permita su extracción.Finally say that, for the disassembly of formwork, once the concrete poured into it has set, it it will be discarded once the rings (12) have been removed, through a vertical disassembly line (13), which corresponds to one of the edges (6), so that by removing a tape adhesive, a steel wire or any other similar element, it produce the opening of the tubular element, this one having a open configuration that allows its extraction.
