DESCRIPCIÓNDESCRIPTION
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un panel de encofrado que presenta una especial estructura interna conseguida mediante el uso de capas textiles adecuadas que dan lugar a un elevado grado de resistencia al impacto .The present invention relates to a formwork panel having a special internal structure achieved by using suitable textile layers that give rise to a high degree of impact resistance.
Este mismo panel incorpora refuerzos de esquina que la protegen frente a impactos. El panel de esta mis- ma invención incorpora una configuración con soluciones constructivas que resultan en un producto con una mejor respuesta frente a la deformación por cambios bruscos de temperatura o por la presencia de humedad.This same panel incorporates corner reinforcements that protect it from impacts. The panel of this same invention incorporates a configuration with constructive solutions that result in a product with a better response to deformation due to sudden changes in temperature or the presence of moisture.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Del mismo solicitante de la presente invención es el panel de encofrado con número de publicación ES1063569U donde se describe un panel caracterizado por una carcasa de fibra de vidrio y resina de poliéster, con unos nervios que definen en la carcasa unos orificios, que albergan listones de madera que forman un panel compacto.Of the same applicant of the present invention is the formwork panel with publication number ES1063569U where a panel characterized by a fiberglass and polyester resin housing is described, with ribs that define holes in the housing, which house slats of wood forming a compact panel.
A pesar de estar reforzado este panel puede romperse si recibe un golpe fuerte tanto en los extremos como en los bordes, lugares que siempre están más expuestos a este tipo de accidentes o agresiones. Para superar los anteriores problemas se ha desarrollado un nuevo panel de encofrado reforzado tanto en la estructura interna del panel como en sus extremos. La mayor solidez y resistencia a los impactos permite su reutilización un mayor número de veces durante el uso en obra .In spite of being reinforced this panel can break if it receives a strong blow both at the ends and at the edges, places that are always more exposed to this type of accidents or aggressions. To overcome the above problems, a new reinforced formwork panel has been developed both in the internal structure of the panel and at its ends. The greater strength and resistance to impacts allows its reuse a greater number of times during use on site.
Desde el punto de vista práctico, se ha compro- bado que un tablero como el descrito en el estado de la técnica y que no incorpora las mejoras reivindicadas en esta invención no verifica los criterios estructurales y resistentes adecuados para su aplicación.From a practical point of view, it has been found that a board such as that described in the state of the art and that does not incorporate the improvements claimed in this invention does not verify the structural and resistant criteria suitable for its application.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
Con la presente invención se pretende superar los problemas de fragilidad de los paneles de encofrado.With the present invention it is intended to overcome the fragility problems of the formwork panels.
En las tareas de desencofrado, por los golpes que se le dan al panel, es cuando más posibilidad hay de que éste se rompa.In the tasks of decoupling, by the blows that are given to the panel, it is when there is more possibility that it will break.
Ya solo la manipulación de los paneles somete a éstos a unas condiciones suficientemente agresivas como para que deban de soportar impactos en las zonas más vulnerables, principalmente las exteriores. Citadas por extensión, las zonas más vulnerables son las constituidas por los bordes del panel, las caras principales del panel y también las esquinas.Only the manipulation of the panels subject them to sufficiently aggressive conditions so that they must withstand impacts in the most vulnerable areas, mainly the outer ones. Cited by extension, the most vulnerable areas are those constituted by the edges of the panel, the main faces of the panel and also the corners.
En éstas últimas, la caída del panel suele producirse siempre sobre las esquinas que provocan una rotura que se propaga según la estructura orientada interna . Para conseguir estos objetivos se ha llevado a cabo un panel de encofrado constituido mediante un cuerpo principal obtenido mediante poltrusionado cuya es- tructura interna presenta una configuración tal que su sección se encuentra aligerada en forma de celdillas. Cada una de las paredes está formada mediante una o más capas textiles embebidas en resina donde la o las capas textiles están constituidas por un tejido, de estructura tejida o no, de fibra de vidrio sobre el que se encuentra fijado, al menos en una de sus caras, o bien un tejido no tejido o bien mechas de un tejido distinto a la fibra de vidrio. A partir de ahora, cuando se diga un tejido de fibra de vidrio se entenderá que este tejido puede ser tejido tejido o tejido no tejido que es como se denomina según si su estructura interna ha sido obtenida tejida o bien es desestructurada.In the latter, the fall of the panel usually always occurs on the corners that cause a break that propagates according to the internal oriented structure. In order to achieve these objectives, a formwork panel constituted by means of a main body obtained by means of polishing has been carried out whose internal structure has a configuration such that its section is lightened in the form of cells. Each of the walls is formed by one or more textile layers embedded in resin where the textile layer (s) are constituted by a fabric, of woven structure or not, of fiberglass on which it is fixed, at least in one of their faces, either a non-woven fabric or wicks of a fabric other than fiberglass. From now on, when a fiberglass fabric is said, it will be understood that this fabric can be woven fabric or nonwoven fabric which is as it is called according to whether its internal structure has been obtained woven or is unstructured.
Adicionalmente, se han incorporado unos refuer- zos de esquina que protegen el panel de los golpes, principalmente por caídas, en los lugares más vulnerables del panel.Additionally, corner reinforcements that protect the panel from bumps, mainly from falls, have been incorporated in the most vulnerable places on the panel.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
La figura 1 muestra un esquema de una capa (1) textil empleada durante el procedimiento de fabricación del panel.Figure 1 shows a scheme of a textile layer (1) used during the manufacturing process of the panel.
La operación de poltrusionado como la empleada en el estado de la técnica es una operación en la que se extrusiona en continuo uno o más tejidos de fibra de vi- drio que quedan embebidos en resina.The polishing operation as used in the prior art is an operation in which one or more glass fiber fabrics that are embedded in resin are continuously extruded.
Los moldes empleados en la operación de poltru- sión sufren un grado de abrasión muy alto por la fibra de vidrio reduciéndose sensiblemente la vida de utiliza- ción de este componente de elevado precio. Si además el grosor del producto final que se necesita obtener es elevado, es necesario incorporar más de un tejido de fibra de vidrio. El valor de la fibra de vidrio es importante para este tipo de productos por lo que un refuerzo basado en el incremento del número de tejidos de fibra de vidrio encarece mucho el producto final .The molds used in the operation of extrusion suffer a very high degree of abrasion by the fiberglass, reducing the life of use of this high price component significantly. If in addition the thickness of the final product that needs to be obtained is high, it is necessary to incorporate more than one fiberglass fabric. The value of fiberglass is important for this type of products, so a reinforcement based on the increase in the number of fiberglass fabrics makes the final product very expensive.
La presente invención evita el uso de una pluralidad de tejidos de fibra de vidrio ya que el grosor final lo consigue fijando a un tejido (1.1) de fibra de vidrio o bien un segundo (1.2) tejido o componente no tejido o bien mechas de un tejido distinto a la fibra de vidrio.The present invention avoids the use of a plurality of fiberglass fabrics since the final thickness is achieved by fixing to a fiberglass fabric (1.1) or a second (1.2) nonwoven fabric or component or wicks of a fabric other than fiberglass.
Este segundo componente (1.2), tal y como muestra el esquema de la figura 2, aporta el volumen necesario para cubrir todo el grosor durante la operación de poltrusión evitando hacer uso de tejidos (1.1) de fibra vidrio adicionales.This second component (1.2), as shown in the scheme of Figure 2, provides the volume necessary to cover the entire thickness during the poltrusion operation avoiding making use of additional glass fiber fabrics (1.1).
Otra ventaja adicional es que el segundo (1.2) componente, constituido o bien mediante un tejido no te- jido, o bien mediante mechas de tejido, no es de fibra de vidrio. Asi, en la operación de poltrusión, el tejido (1.1) de fibra de vidrio no entra en contacto con el molde y no se produce la abrasión por este material.Another additional advantage is that the second (1.2) component, constituted either by a non-woven fabric, or by woven wicks, is not fiberglass. Thus, in the poltrusion operation, the fiberglass fabric (1.1) does not come into contact with the mold and abrasion by this material does not occur.
En este ejemplo, para el segundo material distinto a la fibra de vidrio se hace uso de poliéster, de algodón o bien de una combinación de ambos.In this example, polyester, cotton or a combination of both is used for the second material other than fiberglass.
Si bien el volumen se puede conseguir añadiendo el segundo (1.2) tejido o componente únicamente en una de las caras del tejido (1.1) de fibra vidrio, en este ejemplo de realización se ha incorporado en las dos caras para que no exista contacto directo de el tejido (1.1) de fibra de vidrio con ninguna parte del molde de poltrusionado .While the volume can be achieved by adding the second (1.2) tissue or component only in one of the faces of the fiberglass fabric (1.1), in this exemplary embodiment it has been incorporated in the two faces so that there is no direct contact of the fiberglass fabric (1.1) with any part of the polishing mold.
El modo de fijación entre el tejido (1.1) de fibra vidrio y el segundo (1.2) tejido no tejido o las mechas de poliéster-algodón se han llevado a cabo mediante punzonado.The fixing method between the fiberglass fabric (1.1) and the second (1.2) nonwoven fabric or the polyester-cotton wicks have been carried out by punching.
La figura 2 muestra la estructura del cuerpo (2) principal del panel según un ejemplo de realización obtenido mediante poltrusionado. Este cuerpo (2) principal es el resultado del seccionado del producto obtenido en continuo durante el poltrusionado.Figure 2 shows the structure of the main body (2) of the panel according to an exemplary embodiment obtained by polishing. This main body (2) is the result of the sectioning of the product obtained continuously during the polishing.
Los bordes laterales, ahora son los lados mayores del panel. Estos lados mayores se han reforzado ha- ciendo que las capas (1) textiles de las caras principales del cuerpo (2) principal, prolongadas, se superpongan en este borde.The side edges are now the major sides of the panel. These major sides have been reinforced by making the textile layers (1) of the main faces of the main body (2), prolonged, overlap on this edge.
También se observa que las celdas o celdi- lias (2.2) interiores son de menores dimensiones que las celdillas (2.1) exteriores.It is also observed that the inner cells or cells (2.2) are smaller than the outer cells (2.1).
Con esta configuración, la celdillas (2.2) interiores albergan listones (3), preferentemente de madera, para reforzar la estructura del panel. En este ejemplo de realización se ha hecho uso de madera de baja densidad para reducir el peso global y los listones (3) se han adherido mediante espuma de poliuretano. El resultado es una estructura general de gran rigidez. Los extremos también incorporan listones (3), de madera en este ejemplo aunque podría utilizarse también poliestireno expandido y extruido o PVC, pero de menor longitud.With this configuration, the inner cells (2.2) house slats (3), preferably of wood, to reinforce the structure of the panel. In this embodiment, low density wood has been used to reduce the overall weight and the slats (3) have been adhered by polyurethane foam. The result is a general structure of great rigidity. The ends also incorporate slats (3), made of wood in this example although expanded and extruded polystyrene or PVC could also be used, but of shorter length.
La figura 3 muestra cómo los listones (3) de madera no llegan a los testeros del panel dejando una cavidad que permite introducir un refuerzo de esquina.Figure 3 shows how the wooden slats (3) do not reach the end of the panel leaving a cavity that allows the introduction of a corner reinforcement.
En este ejemplo de realización, el refuerzo de esquina se ha llevado a cabo mediante un bloque (4) de elastómero configurado según un bloque (4.1) de esquina del que emerge un tramo (4.2) de asiento. La figura 4 muestra la transición entre estas dos partes según un escalón (4.1.1) .In this exemplary embodiment, the corner reinforcement has been carried out by an elastomer block (4) configured according to a corner block (4.1) from which a seat section (4.2) emerges. Figure 4 shows the transition between these two parts according to a step (4.1.1).
La figura 3 muestra una línea (L) oblicua en la esquina donde se incorpora el bloque (4) de elastómero. Esta es la línea (L) de corte del cuerpo (2) principal que permite que se ajuste al modo de asiento con el bloque (4) de elastómero tal y como se ha configurado.Figure 3 shows an oblique line (L) in the corner where the elastomer block (4) is incorporated. This is the cutting line (L) of the main body (2) that allows it to fit the seating mode with the elastomer block (4) as configured.
El bloque (4) de elastómero presenta también unas cavidades (4.2.1) para el aligerado.The elastomer block (4) also has cavities (4.2.1) for lightening.
El bloque (4) de elastómero es capaz de absorber los impactos que se producen en la esquina. En este ejemplo se ha hecho coincidir el extremo del listón (3) interno de refuerzo con el tramo (4.2) de asiento de modo que se produce un apoyo. El apoyo evita la rotura por la propagación del esfuerzo durante el impacto.The elastomer block (4) is capable of absorbing the impacts that occur in the corner. In this example, the end of the internal reinforcing slat (3) has been matched with the seat section (4.2) so that a support is produced. The support prevents breakage due to the spread of the effort during the impact.
El uso de un tornillo (5) transversal como el representado en la figura 3 permite fijar el bloque (4) de elastómero al panel.The use of a transverse screw (5) as shown in Figure 3 allows to fix the block (4) from elastomer to panel.
En este ejemplo de realización, además de las soluciones que intervienen en la obtención de un panel más ligero: el uso de una capa (1) textil con mayor volumen por la incorporación del tejido no tejido o de las mechas de poliéster-algodón, el uso de madera de baja densidad, el uso de cavidades (4.2.1) de aligerado; también se ha hecho uso de resina termoestable con carga mineral a la que se le incorpora microesferas de vidrio huecas para aligerar el peso.In this exemplary embodiment, in addition to the solutions involved in obtaining a lighter panel: the use of a textile layer (1) with greater volume due to the incorporation of non-woven fabric or polyester-cotton wicks, use of low density wood, the use of lightened cavities (4.2.1); It has also made use of thermosetting resin with mineral load which is incorporated hollow glass microspheres to lighten the weight.
En otro ejemplo de realización, el refuerzo de esquina se ha llevado a cabo mediante un bloque (5) de elastómero que presenta un bloque (5.1) de esquina del que emerge un tramo (5.2) de asiento destinado a entrar en la celda (2.1) externa del panel (2) y un bloque (5.3) de testero del que emergen tramos (5.4) de asiento para el resto de celdillas (2.2) del panel (2), según se muestra en la Figura 5, lo que permite proteger los testeros del panel (2) y que se puede reemplazar cuando se rompe o se desgaste.In another exemplary embodiment, the corner reinforcement has been carried out by means of an elastomer block (5) having a corner block (5.1) from which a seat section (5.2) emerges destined to enter the cell (2.1). ) external of the panel (2) and a block (5.3) of testero from which sections (5.4) of seat for the rest of cells (2.2) of the panel (2) emerge, as shown in Figure 5, which allows to protect the panel heads (2) and that can be replaced when broken or worn.
Los tramos (5.2, 5.4) de asiento presentan unos tetones (5.2.1, 5.4.1) que se insertan por clipado en unos orificios antagonistas presentes en el panel (no mostrados) .The sections (5.2, 5.4) of the seat have lugs (5.2.1, 5.4.1) that are inserted by clipping into antagonistic holes present in the panel (not shown).
El bloque (5.1) de esquina puede ser inclinado, para acoplarse en la esquina achaflanada de un panel (2) conformada a partir de la linea (L) oblicua. The corner block (5.1) can be inclined, to engage in the chamfered corner of a panel (2) formed from the oblique line (L).
