El panel ajustable para el encofrado de muros curvos objeto de la presente invención es del tipo que comprende cuerpos de chapa de acero o largueros de sección sensiblemente trapecial abierta, dispuestos en la dirección de las generatrices de la superficie curva, fijados al elemento laminar o placa de encofrado, que adoptará la forma curvada necesaria para el muro a realizar y cuyos cuerpos trapeciales están conectados entre sí de forma articulada para permitir el ajuste de la disposición angular mutua de dichos cuerpos o largueros trapeciales para su adaptación a la curva deseada.Adjustable panel for wall formwork curves object of the present invention is of the type comprising steel sheet bodies or crossbars of substantially section open trapecial, arranged in the direction of the generatrices of the curved surface, fixed to the laminar element or plate of formwork, which will adopt the curved shape necessary for the wall to perform and whose trapecial bodies are connected to each other in articulated shape to allow adjustment of angular arrangement mutual of said bodies or trapecial stringers for adaptation to the desired curve
En la Patente U.S.A. 7048249 se da a conocer un encofrado de tipo circular ajustable de este tipo, en el que el ajuste de la disposición angular de cada dos largueros trapeciales adyacentes se efectúa mediante tensores intermedios articulados a dichos largueros y dispuestos a lo largo de los mismos. Por lo tanto, se utilizan múltiples puntos de conexión dispuestos según el desarrollo longitudinal de los largueros, de manera que son necesarios múltiples tensores para ir efectuando el ajuste individual por cada tramo de cada larguero. Ello representa un trabajo muy engorroso y poco satisfactorio, puesto que no existe un enlace mecánico entre los diferentes dispositivos de ajuste de cada larguero.In U.S.A. 7048249 a Adjustable circular type formwork of this type, in which the adjustment of the angular arrangement of every two trapezo stringers adjacent is done by means of intermediate tensioners articulated to said stringers and arranged therein. For the therefore, multiple connection points arranged according to the longitudinal development of the stringers, so that they are multiple tensioners are necessary to adjust individual for each section of each crossbar. It represents a very cumbersome and unsatisfactory work, since there is no mechanical link between the different adjustment devices of each crossbar.
En otros sistemas conocidos según el estado de la técnica se tienen diferentes tipos de elementos de ajuste que se caracterizan también por lo engorroso de su utilización y por la poca precisión del curvado que se consigue del elemento laminar de encofrado, que puede adoptar alabeo.In other systems known according to the state of the technique you have different types of adjustment elements that they are also characterized by the cumbersome use and the poor precision of the bending of the laminar element of formwork, which can adopt warping.
Para solucionar los problemas indicados, en inventor ha ideado, después de pruebas y experimentaciones, un panel ajustable para el encofrado de muros curvos que permite un ajuste rápido del encofrado a la curva deseada con la manipulación de un número muy reducido de puntos de ajuste y con sincronización a lo largo de cada larguero en forma de generatriz del encofrado, de manera que se consigue de forma rápida un ajuste con una gran uniformidad de la curvatura en el sentido de la altura del panel de encofrado, evitando el alabeo de éste por pérdida de paralelismo entre generatrices.To solve the indicated problems, in inventor has devised, after tests and experiments, a panel adjustable for curved wall formwork that allows adjustment fast formwork to the desired curve with the manipulation of a very small number of set points and with synchronization at length of each stringer in the form of a formwork generatrix, of so that you quickly get an adjustment with a large uniformity of curvature in the direction of the panel height formwork, avoiding the warping of this by loss of parallelism Between generatrices.
Para conseguir su objetivo la presente invención prevé la disposición de ejes de sincronización que actúan en las partes superior e inferior entre dos largueros del panel de encofrado curvo y paralelos a los mismos, de manera que, mediante el accionamiento de un eje transversal único de estructura hexagonal se consigue el accionamiento simultaneo de dos ejes longitudinales paralelos que, mediante articulaciones, actúan sobre varios largueros adyacentes, por lo que, por ejemplo, con un solo punto de manipulación es posible efectuar el ajuste de la posición de los dos largueros adyacentes, es decir, es posible ajustar simultáneamente la curvatura de dos segmentos o vanos del elemento laminar de encofrado comprendidos cada uno de ellos entre dos largueros sucesivos. De esta manera resulta posible conseguir un ajuste rápido y eficaz del encofrado y por la sincronización de las partes superior e inferior del panel se evitan deformaciones por alabeo en el tablero de encofrado curvo.To achieve its objective the present invention provides for the provision of synchronization axes that act in the upper and lower parts between two stringers of the panel curved formwork and parallel to them, so that, through the drive of a single transverse axis of hexagonal structure is achieves the simultaneous drive of two longitudinal axes parallels that, through joints, act on several adjacent stringers, so, for example, with a single point of manipulation it is possible to adjust the position of the two adjacent stringers, that is, it is possible to adjust simultaneously the curvature of two segments or spans of the laminar element of formwork including each one between two stringers successive In this way it is possible to achieve a quick adjustment and effective formwork and synchronization of the parts upper and lower panel deformation by warping in The curved formwork board.
Los ejes de sincronización pueden ser ejes giratorios sobre sus propios ejes geométricos o preferentemente pueden quedar constituidos en forma de ejes de cigüeñal giratorios sobre un eje excéntrico determinado por sendos pivotes superior e inferior, con lo que se consigue una construcción más favorable en cuanto a la resistencia de los esfuerzos generados.The synchronization axes can be axes rotating on their own geometric axes or preferably they can be formed in the form of rotating crankshaft shafts on an eccentric axis determined by two upper pivots and lower, which achieves a more favorable construction in as to the resistance of the efforts generated.

Tal como se aprecia en las figuras, el encofrado de muros curvos dotado del objeto de la presente invención comprende de múltiples paneles unidos entre sí mediante mordazas y susceptibles cada uno de ellos de curvado, tal como se ha representado en la figura 1, comprendiendo el elemento laminar adaptable en curva (1) y varios largueros (2) de sección especial que se describirán más adelante, fijados de forma equidistante en el elemento laminar (1), completándose el dispositivo mediante los largueros (3) para cada uno de los bordes, dispuestos respectivamente a la izquierda y a la derecha del panel representado.As can be seen in the figures, the formwork of curved walls provided with the object of the present invention comprises of multiple panels joined together by jaws and each of them susceptible to bending, as it has been represented in figure 1, comprising the laminar element adaptable in curve (1) and several stringers (2) of special section which will be described later, set equidistant from the laminar element (1), the device being completed by means of stringers (3) for each of the edges, arranged respectively to the left and right of the panel represented.
Los diferentes paneles (1) pueden ser acoplados en vertical mediante mordazas (4) y en horizontal mediante mordazas (7) tal como se explicará más delante de forma mas detallada. También disponen de ganchos de suspensión para su elevación y descenso, tal como el gancho (16) de la figura 1.The different panels (1) can be coupled vertically using jaws (4) and horizontally using jaws (7) as will be explained further in more detail. They also have suspension hooks for lifting and descent, such as the hook (16) of Figure 1.
Es característica esencial del panel ajustable para encofrado objeto de la presente invención la sincronización de la regulación del radio de curvatura del elemento (1) mediante una alineación de elementos de ajuste a lo largo de las generatrices del panel para evitar el alabeo de éste con pérdida de paralelismo entre generatrices. Ello se consigue mediante la disposición de ejes (5) paralelos a los largueros del panel y dispuestos uno entre cada dos largueros, tal como se ha representado en la figura 1. Dichos ejes longitudinales (5) son giratorios por la acción de brazos ajustables en longitud (6) que están alojados en uno de los largueros (2) y actúan de manera directa sobre dos ejes longitudinales adyacentes (5) y éstos, mediante las articulaciones que se explicarán, actúan sobre las paredes laterales de los largueros adyacentes. Tal como se aprecia en las figuras 3 y 9 cada brazo ajustable en longitud (6) tiene estructura externa, preferentemente prismática hexagonal, por ser ésta correspondiente a un perfil comercial y presenta orificios internos (8) y (9), roscados en sentido contrario, en los que se alojan sendos vástagos roscados (10) y (11) de manera que el giro del brazo (6), por ejemplo mediante una llave desde el exterior, se traduce en el desplazamiento hacia adentro o hacia fuera de sus respectivos alojamientos de los vástagos roscados (10) y (11) en sentido opuesto entre sí. Dichos vástagos están articulados por sus extremos (12) y (13) a sendas expansiones de los ejes (5) que se han indicado con el numeral (14) y que pueden ser dobles o simples. A este respecto es preciso observar que el ejemplo de realización mediante el brazo (6) con roscado interior y vástagos desplazables (10) y (11) con las articulaciones en los extremos (12) y (13) es solamente un ejemplo constructivo preferente, debiéndose comprender que la conexión entre un mando central y los ejes de ajuste (5) se podría conseguir mediante cualquier otro dispositivo mecánico convencional.It is essential feature of adjustable panel for formwork object of the present invention the synchronization of the regulation of the radius of curvature of the element (1) by means of a alignment of adjustment elements along the generatrices of the panel to prevent warping of the latter with loss of parallelism between generatrices This is achieved through the arrangement of axes (5) parallel to the panel stringers and arranged one in two stringers, as shown in figure 1. These axes Longitudinal (5) are rotatable by the action of adjustable arms in length (6) that are housed in one of the stringers (2) and they act directly on two adjacent longitudinal axes (5) and these, through the joints that will be explained, act on the side walls of adjacent stringers. As it see in figures 3 and 9 each arm adjustable in length (6) it has an external structure, preferably hexagonal prismatic, by be this corresponding to a commercial profile and has holes internal (8) and (9), threaded in the opposite direction, in which they house two threaded rods (10) and (11) so that the rotation of the arm (6), for example by means of a key from the outside, translates into shifting in or out of their respective threaded rod housings (10) and (11) in opposite direction to each other. These stems are articulated by their ends (12) and (13) to both expansions of the shafts (5) that have been indicated with the numeral (14) and that can be double or simple. TO In this regard, it should be noted that the example by means of the arm (6) with internal threading and movable rods (10) and (11) with the joints at the ends (12) and (13) is only a preferred constructive example, being understood that the connection between a central control and the adjustment shafts (5) is could get by any other mechanical device conventional.
El brazo (6) queda fijado con capacidad de giro en uno de los largueros (2), por ejemplo, mediante la disposición mostrada en las figuras 3, 7 y 9 mediante el collar (15) y la correspondiente ranura si bien, tal como es de comprender, también se podría conseguir con cualquier otro tipo de montaje mediante un casquillo envolvente, cojinete, etc.The arm (6) is fixed with turning capacity in one of the stringers (2), for example, by arrangement shown in figures 3, 7 and 9 by the collar (15) and the corresponding slot though, as you understand, also it could be achieved with any other type of assembly by means of a bushing, bearing, etc.
Los ejes longitudinales (5) paralelos a los largueros se relacionan con los largueros adyacentes mediante bielas (24), tal como es de observar en las mismas figuras 3 y 9.The longitudinal axes (5) parallel to the stringers are related to adjacent stringers by connecting rods (24), as can be seen in the same figures 3 and 9.
En la parte superior de los ejes (5) se disponen asimismo elementos de accionamiento que actúan sobre los largueros mediante bielas de conexión y con la disposición de las barras transversales (17) que presentan orificios colisos (18) que están conectados mediante dos pivotes pasantes con las expansiones (19), que son prolongación lateral de los largueros adyacentes.At the top of the shafts (5) are arranged also drive elements that act on the stringers by connecting rods and with the arrangement of the bars cross sections (17) that have collision holes (18) that are connected by two through pivots with the expansions (19), which are lateral extension of adjacent stringers.
Los orificios colisos tienen forma de arco de círculo con el centro en la cara interior del panel de encofrado, con lo que la longitud del arco de circunferencia entre dos generatrices se mantiene constante a lo largo del todo el recorrido de regulación.The collision holes are shaped like an arc of circle with the center on the inside of the formwork panel, bringing the length of the circumference arc between two generatrices remains constant throughout the entire journey of regulation.
En la parte inferior, la conexión entre los ejes
(5) y los largueros (2) es análoga a la descrita para la parte
superior mediante bielas de conexión (20), no representadas en la
parte superior, así como alas (19) y barras transversales
(17).In the lower part, the connection between the shafts (5) and the stringers (2) is analogous to that described for the upper part by connecting rods (20), not shown at the top, as well as wings (19) and crossbars
(17).
Tal como se ha indicado anteriormente, los ejes
de sincronización pueden ser giratorios sobre sus propios ejes
geométricos o preferentemente pueden tener disposición de ejes de
cigüeñal, tal como se mostrará en las figuras, preferentemente, en
las figuras 4, 9 y 12. En efecto, en dichas figuras se observa que
de manera fija a uno de los largueros (2) que presenta el eje de
accionamiento (6) y con intermedio de las barras superior e inferior
(17), los ejes (5) quedan montados en forma de eje cigüeñal mediante
alas (34) que se articulan mediante pivotes verticales (35) que
determinan un eje de giro excéntrico. El montaje de un eje (5) en
forma de cigüeñal se muestra también en la figura 15 y en la sección
de la figura 16, observándose igual disposición en la parte superior
y en la parte
inferior.As indicated above, the synchronization axes can be rotatable on their own geometric axes or preferably they can have crankshaft axes, as will be shown in the figures, preferably in Figures 4, 9 and 12. Indeed , in said figures it is observed that in a fixed way to one of the stringers (2) that has the drive shaft (6) and through the upper and lower bars (17), the axes (5) are mounted in the form of crankshaft axis by means of wings (34) that are articulated by vertical pivots (35) that determine an eccentric axis of rotation. The assembly of a crankshaft-shaped shaft (5) is also shown in Figure 15 and in the section of Figure 16, the same arrangement being observed in the upper part and in the part
lower.
En las figuras 17 y 18 se aprecia la articulación de uno de los ejes de sincronización (5) con un larguero adyacente (2), mediante bieletas intermedias (36), de manera que el giro de dichos ejes de sincronización se transmite a dichos largueros adyacentes (2).Figures 17 and 18 show the articulation of one of the synchronization axes (5) with a adjacent stringer (2), by intermediate connecting rods (36), of so that the rotation of said synchronization axes is transmitted to said adjacent stringers (2).
Los largueros (2) tienen una estructura especial que se aprecia especialmente en las figuras 6 a 9 y 12. En especial en la figura 12 se puede observar que dichos largueros presentan una columna central con estructura prismática o similar que otorga gran rigidez al larguero y que, en el caso representado en las figuras comprende una estructura prismática pentagonal de caras laterales (25) y (26) sensiblemente perpendiculares al elemento laminar de encofrado (1), y otras dos caras (27) y (28) inclinadas con respecto a las caras laterales (25) y (26) y una última cara (29) perpendicular a dichas caras laterales (25) y (26) y sensiblemente paralela al elemento laminar (1). El larguero se completa mediante dos alas oblicuas (30) y (31) fijadas mediante pestañas y tornillos al elemento laminar de encofrado (1). Dichas columnas de refuerzo de los largueros está dotada de aberturas para mordazas u otro tipo de acceso tales como las aberturas longitudinales superiores (32) y las aberturas en "ojo de cerradura" (33) y otras similares.The stringers (2) have a special structure which can be seen especially in figures 6 to 9 and 12. Especially in figure 12 it can be seen that said stringers have a central column with prismatic or similar structure that grants great stiffness to the stringer and that, in the case represented in the figures It comprises a pentagonal prismatic structure with lateral faces (25) and (26) substantially perpendicular to the laminar element of formwork (1), and two other faces (27) and (28) inclined with respect to the side faces (25) and (26) and one last face (29) perpendicular to said lateral faces (25) and (26) and substantially parallel to the laminar element (1). The crossbar is completed by two oblique wings (30) and (31) fixed by means of tabs and screws to the laminar formwork element (1). Said reinforcing columns of the stringers are equipped with openings for jaws or other types of access such as the upper longitudinal openings (32) and the openings in "keyhole" (33) and similar ones.
En las figuras 13 y 14 se observa en detalle la construcción de un larguero lateral (3) de tipo abierto que presenta caras rectas, dando lugar a una estructura general prismática que en su cara frontal presenta una abertura longitudinal (46) para la entrada de una de las mandíbulas de una mordaza de unión en vertical de un panel ajustable de muro con otro situado en la parte superior, tal como se aprecia en el detalle de la figura 11. La cara frontal del larguero (3) presenta un tope longitudinal (45) destinado a limitar la posición transversal de la mordaza para que los brazos de la misma no interfieran interiormente en el larguero (3). Interiormente, el larguero presenta una chapa escalonada (37) unida por sendas pestañas (38) y (39) de sus bordes, preferentemente mediante soldadura láser, respectivamente a la cara frontal del larguero (3) y al borde (40) de la cara lateral (47) del larguero (3). El larguero presenta en el borde del otro lado (48) una segunda pestaña (41) de estructura similar a la pestaña (39), permitiendo esta disposición la fijación mediante tornillos (42) a la pieza laminar de encofrado (1), tal como se observa en la figura 14. La fijación del larguero al elemento laminar de encofrado (1) se realiza por una parte mediante los mencionados tornillos (42) que fijan la pestaña (41), y por otra, mediante largos tornillos transversales (43) que atraviesan el larguero y que se incorporan en la cara frontal del elemento de encofrado (1) mediante una cabeza ensanchada (50) que queda enrasada con dicho panel. Los tornillos (43) quedan fijados mediante tuercas (49) que, al igual que los tornillos (42), son accesibles por la parte interior del encofrado, lo que permite un fácil acceso a dichos tornillos a efectos de mantenimiento del panel, desmontaje del elemento laminar (1) después de haber efectuado una o varias obras, sustituyéndolo por un elemento laminar nuevo u otros trabajos. Se debe tener en cuenta además que el hecho de que los tornillos sean accesibles desde la cara posterior del panel de encofrado, facilitan doblemente el trabajo de desmontaje, puesto que en dicha cara el ensuciamiento producido por el vertido de hormigón es muy reducido.Figures 13 and 14 show in detail the construction of an open type lateral stringer (3) that presents straight faces, giving rise to a general prismatic structure that in its front face has a longitudinal opening (46) for entrance of one of the jaws of a vertical joint jaw of an adjustable wall panel with another one located at the top, as can be seen in the detail of figure 11. The front face of the stringer (3) has a longitudinal stop (45) intended for limit the transverse position of the jaw so that the arms of it does not interfere internally with the crossbar (3). Inside, the stringer has a stepped sheet (37) attached by two tabs (38) and (39) of its edges, preferably by laser welding, respectively to the front face of the crossbar (3) and to the edge (40) of the side face (47) of the crossbar (3). The crossbar has on the edge of the other side (48) a second tab (41) of similar structure to tab (39), allowing this arrangement fixing by screws (42) to the piece laminar formwork (1), as shown in figure 14. The fixing the crossbar to the formwork laminar element (1) made on the one hand by means of the aforementioned screws (42) that fix the flange (41), and on the other, by long screws cross sections (43) that cross the crossbar and are incorporated into the front face of the formwork element (1) by means of a head widened (50) that is flush with said panel. Screws (43) are fixed by nuts (49) which, like the screws (42), are accessible from the inside of the formwork, which allows easy access to these screws for the purpose of panel maintenance, disassembly of the laminar element (1) after having done one or more works, replacing it with a New laminar element or other work. Should consider in addition to the fact that the screws are accessible from the back side of the formwork panel, double facilitate the disassembly work, since in said face the fouling produced by the pouring of concrete is very small.
Una tapa superior (44) efectúa el cierre de la columna constituida por la chapa interna doblemente escalonada (37) y las paredes directamente opuestas a la misma del larguero (3).An upper cover (44) closes the column consisting of the double stepped internal sheet (37) and the walls directly opposite it from the crossbar (3).
En la figura 10 se ha representado la disposición de una mordaza para el acoplamiento de dos paneles de encofrado por sus bordes laterales, habiéndose mostrado solamente uno de ellos correspondiente al larguero (3) de las figuras 13 y 14. Tal como se aprecia en dicha figura, la mordaza fijará un panel al adyacente al coincidir sus mandíbulas en las chapas internas doblemente acodadas (37) incorporadas en el interior de los largueros (3).In figure 10 the jaw arrangement for the coupling of two panels of formwork by its lateral edges, having shown only one of them corresponding to the crossbar (3) of figures 13 and 14. As can be seen in this figure, the jaw will fix a panel to the adjacent to matching their jaws on the inner plates doubly angled (37) incorporated inside the stringers (3).
