DESCRIPCIÓNDESCRIPTION
La presente invención está destinada a dar a conocer un panel de características ventajosas para el encofrado de muros y pilares.The present invention is intended to disclose a panel of advantageous features for the formwork of walls and pillars.
Como es sabido, en la construcción de obras se presenta la necesidad de encofrar los elementos de la estructura, en particular muros y pilares. En la actualidad se dispone de diferentes tipos de paneles de encofrado para determinar el volumen que ocupará el muro una vez colocadas las armaduras y vertido el hormigón y también se dispone de paneles para la construcción de pilares en los que se debe resolver el montaje de los diferentes paneles formando un recinto cerrado por las caras laterales que tiene la estructura del pilar, es decir, usualmente prismática recta, muy alargada.As is known, in the construction of works there is a need to form the elements of the structure, in particular walls and pillars. At present, different types of formwork panels are available to determine the volume that the wall will occupy once the reinforcements have been placed and the concrete has been poured and there are also panels for the construction of pillars in which the assembly of the different panels forming an enclosure enclosed by the lateral faces that have the structure of the pillar, that is, usually straight prismatic, very elongated.
El objetivo de la presente invención estriba en dar a conocer paneles que simultáneamente pueden ser utilizados para el encofrado de muros y de pilares. Otro objetivo de la presente invención estriba en la realización de los paneles para encofrado de muros y pilares simplemente en chapa metálica doblada y travesanos de refuerzo, evitando las estructuras habitualmente utilizadas de tipo tubular formando un marco y separadamente la placa que determina la cara de encofrado.The objective of the present invention is to present panels that can simultaneously be used for the formwork of walls and pillars. Another objective of the present invention is in the realization of the panels for formwork of walls and pillars simply in folded sheet metal and reinforcing crossbars, avoiding the commonly used structures of tubular type forming a frame and separately the plate that determines the formwork face .
Otro objetivo de la presente invención estriba en dar a conocer medios para el acoplamiento rápido y seguro de los paneles para muros por sus bordes laterales.Another objective of the present invention is to provide means for quick and safe coupling of the wall panels by their lateral edges.
Otro objetivo de la presente invención estriba en dar a conocer medios para el acoplamiento de los paneles perpendicularmente entre sí de forma ajustable para conseguir el encofrado de un pilar de dimensiones variables.Another objective of the present invention is based on disclose means for coupling the panels perpendicularly to each other in an adjustable way to achieve the formwork of a pillar of varying dimensions.
Los objetivos de la presente invención se consiguen por la constitución del panel de encofrado mediante un elemento de chapa metálica doblada por los bordes formando sendos perfiles en forma de L, para delimitar los bordes laterales del panel de encofrado y recibiendo interiormente largueros y travesanos asimismo en forma de perfiles, por ejemplo, perfiles en U, para el refuerzo del panel y para recibir los elementos de interconexión de los paneles lateralmente para el encofrado de muros o perpendicularmente para el encofrado de pilares.The objectives of the present invention are achieved by the constitution of the formwork panel by means of a metal sheet element folded by the edges forming individual L-shaped profiles, to delimit the side edges of the formwork panel and receiving inwardly stringers and crossbars also in form of profiles, for example, U-profiles, for the reinforcement of the panel and for receiving the interconnection elements of the panels laterally for wall formwork or perpendicularly for pillar formwork.
Los elementos de conexión de los paneles entre sí quedan constituidos por vastagos roscados con cabeza en punta de flecha que quedan asociados preferentemente a dos lados del panel, permitiendo realizar la unión de los paneles con otros adyacentes al penetrar la cabeza en forma de punta de flecha en el interior de un orificio de forma conjugada del panel montado en oposición, permitiendo su giro para impedir su salida. La fijación de cada uno de los elementos de retención se efectúa simplemente por una tuerca con aletas de fácil manipulación que se rosca a lo largo del mismo y que queda aplicada por apriete en un puente postizo fijado a su vez a los laterales del panel.The connecting elements of the panels to each other are constituted by threaded rods with an arrowhead that are preferably associated to two sides of the panel, allowing the panels to be joined with adjacent ones by penetrating the head in the form of an arrowhead. inside a hole of conjugate form of the panel mounted in opposition, allowing its rotation to prevent its exit. The fixing of each of the retaining elements is carried out simply by a nut with easily manipulated fins that is threaded along it and which is applied by tightening on a false bridge fixed in turn to the sides of the panel.
Los mencionados elementos de unión con los paneles adyacentes, compuestos por el vastago de unión con cabeza en punta de flecha y la tuerca de aletas de fijación así como el puente de apriete, tiene dimensiones tales que quedan incluidos en la anchura que corresponde a los laterales del panel, de manera que no sobresalgan transversalmente al panel a efectos de permitir un fácil apilamiento y transporte.The aforementioned connecting elements with the adjacent panels, composed of the connecting rod with an arrowhead and the fixing wing nut as well as the clamping bridge, have dimensions such that they are included in the width corresponding to the sides of the panel, so that they do not protrude transversely to the panel in order to allow easy stacking and transport.
Para el acoplamiento de los paneles por sus bordes laterales para el encofrado de muros, se prevé que todos los laterales del panel quedarán dotados de múltiples aberturas de forma conjugada a los elementos de fijación explicados, es decir, de forma conjugada a la de la punta de flecha o similar de los extremos de los vastagos roscados a efectos de permitir el acoplamiento de paneles uno al lado de otro en las posiciones de altura deseadas.For the coupling of the panels by their lateral edges for the formwork of walls, it is envisaged that all the sides of the panel will be provided with multiple openings in conjugate form to the explained fasteners, that is, in conjugate form to that of the tip of arrow or similar of the ends of the threaded rods in order to allow the coupling of panels side by side in the desired height positions.
Los elementos de sujeción de los paneles por sus bordes laterales para el encofrado de muros se dispondrán preferentemente en dos lados perpendiculares del panel y se preverán montajes en paneles descentrados con respecto a otros para impedir que al unir paneles por las caras dotadas de elementos de fijación, se pueda producir la interferencia de los elementos de fijación de un panel con los del adyacente. Para permitir el montaje de los paneles perpendicularmente para el encofrado de muros se prevé la disposición en la cara interna del panel, es decir, opuesta a la cara de encofrado, de perfiles específicos dotados de una hilera de aberturas para acoplamiento de las cabezas en punta de flecha o similares de los elementos de sujeción de otro panel, que de esta manera permitirá fijar un panel a otro perpendicularmente entre sí para delimitar el espacio prismático de una columna.The fasteners of the panels by their lateral edges for the formwork of walls will preferably be arranged on two perpendicular sides of the panel and assemblies in offset panels with respect to others will be provided to prevent the joining of panels by the faces provided with fasteners. , interference of the fasteners of a panel with those of the adjacent one may occur. In order to allow the panels to be mounted perpendicularly for wall formwork, the arrangement on the internal side of the panel is provided, that is, opposite the formwork face, of specific profiles provided with a row of openings for coupling the pointed heads of arrow or similar of the fasteners of another panel, which in this way will allow to fix one panel to another perpendicularly to each other to delimit the prismatic space of a column.
Para su mejor comprensión se adjuntan, a título de ejemplo explicativo pero no limitativo, unos dibujos - A -For your better understanding, some drawings are attached by way of explanatory but not limiting example - TO -
correspondientes a un ejemplo de realización de la presente invención.corresponding to an embodiment of the present invention.
Las figuras 1 , 2 y 3 muestran vistas de un panel en el que se aprecian dos de sus bordes laterales y una vista en alzado por la cara posterior del panel.Figures 1, 2 and 3 show views of a panel in which two of its lateral edges and an elevation view of the rear face of the panel can be seen.
La figura 4 muestra una vista con dos paneles acoplados por sus lados menores.Figure 4 shows a view with two panels coupled by their smaller sides.
La figura 5 es una vista similar a la figura 4 mostrando dos paneles acoplados por sus lados de mayor longitud.Figure 5 is a view similar to Figure 4 showing two panels coupled at their sides of greater length.
Las figuras 6 y 7 muestran respectivamente una vista en alzado y sección parcial y una vista en planta de los paneles de la invención dispuestos para el encofrado de un pilar. Tal como se aprecia en las figuras, el panel para encofrado de muros y pilares objeto de la presente invención comprende un elemento de chapa metálica que determina la cara de encofrado del panel de encofrado propiamente dicho -1- de forma rectangular con cuatro lados -2-, -3-, -4- y -5- cuya estructura corresponde preferentemente a un perfil en forma de L tal como se observa en la figura 6, mostrando los lados -6- y -7- que, por doblado de la chapa, constituye los lados del panel, que substituyen los habituales elementos tubulares. El panel queda reforzado mediante un número variable de travesanos -8-, -8'-... así como largueros tales como los indicados con los numerales -9- y -10-.Figures 6 and 7 respectively show an elevation view and partial section and a plan view of the panels of the invention arranged for the formwork of a pillar. As can be seen in the figures, the wall and pillar formwork panel object of the present invention comprises a sheet metal element that determines the formwork face of the formwork panel itself -1- rectangular in shape with four sides -2 -, -3-, -4- and -5- whose structure preferably corresponds to an L-shaped profile as shown in Figure 6, showing the sides -6- and -7- which, by bending the sheet , constitutes the sides of the panel, which replace the usual tubular elements. The panel is reinforced by a variable number of crossbars -8-, -8 '-... as well as stringers such as those indicated with numerals -9- and -10-.
Todos los lados -2-, -3-, -4- y -5- del panel quedan dotados de múltiples alineaciones de orificios tales como los indicados con los numerales -11-, -11'-, -11"-... en la figura 1 y -12-, -12'-, -12"-... en la figura 3. Ello permite el acoplamiento de paneles por sus laterales para el encofrado de muros, tal como se observa en las figuras 4 y 5, habiéndose mostrado en la figura 4 dos paneles -13- y -14- unidos por sus lados menores -15- y -16- y en la figura 5, dos paneles -17- y -18- unidos por dos de sus lados mayores -19- y -20-.All sides -2-, -3-, -4- and -5- of the panel are provided with multiple hole alignments such as those indicated by numerals -11-, -11'-, -11 "-... in figure 1 and -12-, -12'-, -12 "-... in figure 3. This allows the coupling of panels on their sides for the formwork of walls, as seen in figures 4 and 5, having shown in Figure 4 two panels -13- and -14- joined by their smaller sides -15- and -16- and in Figure 5, two panels -17- and -18- joined by two of their sides older -19- and -20-.
La unión de dos paneles por sus lados se efectúa preferentemente mediante la disposición de elementos de acoplamiento en la parte interna de dos lados perpendiculares de los paneles, tal como se muestra en la figura 2, en la que se han representado dos elementos de fijación respectivamente en los lados -2- y -3-, que se han designado con los numerales -21- y -21'- así como -22- y -22'-. Dichos dispositivos de fijación están integrados por una varilla roscada -23-, figura 2, terminada en una cabeza -24- cuya forma transversal es conjugada de la forma de los orificios de los laterales -11-, -11'-, -11"-... y -12-, -12'-, -12"-..., todos los cuales son iguales. La varilla -23- está montada sobre un puente -25- de soporte fijado a su vez al lateral del panel y recibe exteriormente una robusta tuerca de fácil manipulación -26- para el apriete del dispositivo de fijación cuyo funcionamiento resulta evidente, puesto que funciona simplemente por introducción de la punta de flecha o similar -24- en el orificio correspondiente del panel enfrentado, quedando retenido en su interior después de un giro, por ejemplo de 90°, de la varilla, de manera que la cabeza en punta de flecha -24- quedará dispuesta transversalmente al correspondiente orificio, después de lo cual se efectuará el apriete mediante la tuerca -26-.The joining of two panels on their sides is preferably effected by the arrangement of coupling elements on the inner part of two perpendicular sides of the panels, as shown in Figure 2, in which two fasteners have been represented respectively on sides -2- and -3-, which have been designated with the numerals -21- and -21'- as well as -22- and -22'-. Said fixing devices are integrated by a threaded rod -23-, figure 2, terminated in a head -24- whose cross-sectional shape is conjugated to the shape of the side holes -11-, -11'-, -11 " -... and -12-, -12'-, -12 "-..., all of which are equal. The rod -23- is mounted on a support bridge -25- fixed in turn to the side of the panel and externally receives a robust nut of easy handling -26- for tightening the fixing device whose operation is evident, since it works simply by inserting the arrowhead or the like -24- into the corresponding hole of the opposite panel, being retained inside it after a rotation, for example of 90 °, of the rod, so that the arrowhead -24- will be arranged transversely to the corresponding hole, after which the tightening will take place using the nut -26-.
Como se comprenderá, la forma específica de la cabeza del dispositivo de fijación podrá variar entre amplios límites siempre que se cumpla la condición de que su forma resulte conjugada de la del orificio del lateral del panel en el que se debe fijar y que su fijación tenga lugar después de un giro que impida su salida. Así por ejemplo, cualquier tipo de gancho podría ser utilizado siempre y cuando cumpla con las características mencionadas de forma transversal de la punta conjugada de la forma del orificio correspondiente y con capacidad de retención después de un giro angular para impedir su salida.As will be understood, the specific shape of the head of the fixing device may vary between wide limits provided that the condition is met that its shape is conjugated to that of the hole in the side of the panel in which it is to be fixed and that its fixing has place after a turn that prevents its exit. Thus, for example, any type of hook could be used as long as it meets the aforementioned cross-sectional characteristics of the conjugate tip of the corresponding hole shape and with retention capacity after an angular rotation to prevent its exit.
A continuación se describirán los medios utilizados en el panel objeto de la presente invención para permitir su montaje para el encofrado de pilares, tal como se representa en la figura 6 y 7. En la figura 7 se han representado cuatro paneles acoplados perpendicularmente entre sí, indicados con los numerales -27-, -28-, -29- y -30- que determinan un espacio central -31- que corresponde a la sección transversal deseada para el pilar. Para permitir el acoplamiento de dichos paneles, éstos presentan interiormente perfiles, por ejemplo, -32- y -33-, paralelos a la cara de encofrado y dotados de sendas alineaciones de orificios de acoplamiento de elementos de fijación de igual forma a los representados en las figuras 1 y 3. De este modo, los elementos de fijación de los bordes laterales de un panel, por ejemplo, el panel -30- de las figuras 6 y 7, y que se han designado con los numerales -34- y -35-, se pueden introducir en los orificios deseados de los perfiles transversales del panel dispuesto perpendicularmente, en el caso representado el panel -29-, efectuándose la fijación de igual manera que la que tiene lugar para la prolongación lateral de los paneles para el encofrado de muros.Next, the means used in the panel object of the present invention to allow its assembly for the formwork of pillars will be described, as shown in Figure 6 and 7. In Figure 7 four panels perpendicularly coupled to each other are shown, indicated with the numerals -27-, -28-, -29- and -30- that determine a central space -31- corresponding to the desired cross section for the pillar. In order to allow the coupling of said panels, they have internally profiles, for example, -32- and -33-, parallel to the formwork face and provided with alignments of coupling holes of fixing elements in the same way as those shown in Figures 1 and 3. Thus, the fixing elements of the side edges of a panel, for example, the panel -30- of Figures 6 and 7, and which have been designated with the numbers -34- and - 35-, they can be introduced into the desired holes of the transverse profiles of the panel arranged perpendicularly, in the case represented the panel -29-, the fixing being carried out in the same way as that which takes place for the lateral extension of the panels for the wall formwork.
Para el acoplamiento de dos paneles paralelamente entre sí, para el encofrado de muros de dos caras, los paneles presentan orificios pasantes para introducir los correspondientes tirantes, los cuales se han indicado con los numerales -36-, -37-, -38- y -39- en la figura 2.For the coupling of two panels parallel to each other, for the formwork of double-sided walls, the panels have through holes to introduce the corresponding braces, which have been indicated with the numbers -36-, -37-, -38- and -39- in figure 2.
