Description
Dispositivo para el accionamiento de plataformas desplazables horizontalmente.Platform drive device horizontally scrollable.
La presente invención está destinada a dar a conocer un dispositivo para el accionamiento de plataformas desplazables horizontalmente, que aporta sensibles características de novedad y actividad inventiva al sector al se destina.The present invention is intended to give know a device for platform operation horizontally scrollable, which provides sensitive features of novelty and inventive activity to the sector to which it is intended.
El dispositivo objeto de la presente invención será aplicable al accionamiento de plataformas desplazables preferentemente en construcción, en el sector de los andamios llamados "trepantes", es decir, andamios desplazables verticalmente en los que una plataforma simple o múltiple es utilizada para soportar los paneles de encofrado de cada tramo vertical construido, desplazándose de abajo hacia arriba a medida que se van construyendo el muro o estructura vertical de hormigón armado.The device object of the present invention It will be applicable to the operation of movable platforms preferably under construction, in the scaffolding sector called "climbers", that is, movable scaffolding vertically in which a single or multiple platform is used to support the formwork panels of each section built vertical, moving from bottom to top as that the vertical concrete wall or structure is being built armed.
Cada vez que se ha encofrado y hormigonado un tramo del muro o estructura vertical y después del tiempo necesario de fraguado mínimo, la estructura debe ser desplazada hacia arriba para encofrar un tramo sucesivo, hasta llegar al final del muro o estructura vertical. Cuando se debe hacer el desplazamiento ascendente, una operación necesaria es la de limpiar la superficie del panel de encofrado, eliminando residuos del encofrado que se acaba de realizar y, eventualmente, recubrir dicha superficie con una sustancia desmoldeante, etc. En todo caso es necesario poder desplazar la plataforma que soporta el panel de encofrado sobre un plano horizontal, para liberar un espacio entre el muro parcialmente fraguado y el propio panel de encofrado para permitir que uno o más operarios puedan realizar dicho trabajo.Each time a formwork has been concreted and concreted section of the wall or vertical structure and after the necessary time minimum setting, the structure must be moved up to form a successive section, until reaching the end of the wall or vertical structure When the displacement should be done ascending, a necessary operation is to clean the surface of the formwork panel, eliminating waste from the formwork just made and eventually cover said surface with a release agent, etc. In any case it is necessary to be able to move the platform that supports the formwork panel on a horizontal plane, to free a space between the wall partially set and the formwork panel itself to allow that one or more operators can perform said work.
A propio tiempo, también es necesario, en el funcionamiento de este tipo de plataformas, el poder presionar el panel de encofrado sobre el borde superior del muro ya realizado para conseguir buena estanqueidad para el encofrado del tramo siguiente del muro o estructura vertical.At the same time, it is also necessary, in the operation of this type of platforms, to be able to press the formwork panel on the upper edge of the wall already made to achieve good sealing for the formwork of the section following the wall or vertical structure.
Dadas las considerables dimensiones y peso de dichas estructuras portadoras de los paneles de encofrado, se presenta una sensible dificultad para realizar el desplazamiento horizontal y eventual compresión de la plataforma, por lo que los mecanismos actualmente conocidos para realizar la separación de la plataforma desplazándola horizontalmente son dispositivos complejos que se basan en efectuar el guiado de la plataforma sobre guías horizontales de la base sobre la que se apoya dicha plataforma, y mecanismos de considerable envergadura para permitir el desplazamiento horizontal de separación y de compresión de la plataforma, desplazándose sobre dichas guías. Estos dispositivos actualmente conocidos son complejos por su estructura y de difícil mantenimiento, puesto que en el hormigonado de muros verticales se producen gran cantidad de desperdicios, polvo, suciedad y las guías horizontales requieren un mantenimiento continuado que es engorroso y requiere considerable mano de obra.Given the considerable dimensions and weight of said carrier structures of the formwork panels, are It presents a sensitive difficulty to perform the displacement horizontal and eventual compression of the platform, so that currently known mechanisms to perform separation of the horizontally moving platform are complex devices which are based on guiding the platform on guides horizontal of the base on which said platform rests, and considerable mechanisms to allow horizontal displacement and compression offset of the platform, moving over said guides. These devices currently known are complex because of their structure and difficult maintenance, since in the concreting of vertical walls produce large amount of waste, dust, dirt and guides horizontals require continued maintenance that is cumbersome and requires considerable labor.
Por todas las razones expuestas es necesario disponer pesados mecanismos de accionamiento manual en cada una de las guías, con ayuda de mecanismos habitualmente de piñón/cremallera y cuña de apriete, que requieren un mínimo de dos operarios actuando simultáneamente en cada uno de los mecanismos correspondientes a una de las guías.For all the reasons stated it is necessary have heavy manual drive mechanisms in each of the guides, with the help of mechanisms usually pinion / rack and tightening wedge, which require a minimum of two operators acting simultaneously on each of the mechanisms corresponding to one of the guides.
Para reducir los inconvenientes anteriormente mencionados el inventor ha procedido al desarrollo de un mecanismo para el accionamiento de plataformas desplazables horizontalmente del tipo que se ha descrito de manera que permite conseguir un accionamiento muy simple y un fácil bloqueo por la acción del propio mecanismo, que impide el retroceso una vez efectuada la aplicación.To reduce the inconvenience above mentioned the inventor has proceeded to the development of a mechanism for driving horizontally movable platforms of the type that has been described so as to allow a very simple drive and easy blocking by the action of the own mechanism, which prevents the recoil once the application.
La presente invención queda definida por la parte caracterizante de la reivindicación 1.The present invention is defined by the characterizing part of claim 1.
Otras características de la invención quedan definidas en las reivindicaciones dependientes.Other features of the invention remain defined in the dependent claims.
A título de ejemplo, el dispositivo de accionamiento objeto de la presente invención comprende un brazo de palanca principal articulado a soportes fijados en la base sobre la que se desplaza la plataforma portadora del panel de encofrado del muro o estructura similar, articulándose además dicho brazo principal mediante un brazo auxiliar de longitud ajustable y que actúa de tensor, a la propia plataforma portadora del encofrado vertical. El mecanismo se aplica paralelamente a cada una de las guías de los lados de la plataforma desplazable, de manera que ésta resulta accionable por cualquiera de los dos lados. La disposición del brazo principal, brazo auxiliar intermedio y puntos de apoyo es tal que la posición de tope de trabajo del encofrado coincide con la posición horizontal del brazo principal de accionamiento, con lo que un movimiento de éste resulta irreversible por sí mismo, efectuando el bloqueo de la plataforma de modo automático. También la posición de la plataforma que corresponde a la separación máxima del encofrado con respecto al muro corresponde a la posición horizontal del brazo principal de accionamiento, con lo que se consigue una posición de bloqueo equivalente a la posición de trabajo, que impide el desplazamiento fortuito de la plataforma si no se actúa manualmente sobre el brazo principal levantando el mismo, lo que se traduce en el desplazamiento de la plataforma.As an example, the device drive object of the present invention comprises an arm of main lever articulated to supports fixed in the base on the that the carrier platform of the formwork panel of the wall or similar structure, said arm also being articulated main by means of an auxiliary arm of adjustable length and that acts as a tensioner, to the formwork carrier itself vertical. The mechanism is applied in parallel to each of the guides on the sides of the movable platform, so that it It is operable on either side. The disposition of the main arm, intermediate auxiliary arm and support points is such that the working stop position of the formwork coincides with the horizontal position of the main drive arm, with that a movement of this is irreversible by itself, blocking the platform automatically. Too the position of the platform that corresponds to the maximum separation of the formwork with respect to the wall corresponds to the position horizontal of the main drive arm, so that get a blocking position equivalent to the position of work, which prevents the accidental displacement of the platform if the main arm is not operated manually by lifting the same, which translates into the displacement of the platform.

Tal como se representa en las figuras, la presente invención es aplicable a un conjunto para encofrado de muros o estructuras verticales (1), comprendiendo de modo convencional una plataforma de trabajo (2) que puede quedar asociada a una segunda plataforma inferior (3), destinadas ambas al personal que efectúa sus labores en dichas plataformas, que están destinadas a soportar un armazón desplazable (4) portador de uno o varios paneles (12) destinados al encofrado progresivo del muro o estructura vertical (1). El conjunto de dichas plataformas (2), (3) y armazón (4) con los paneles de encofrado (12) queda incorporado sobre el muro (1) facilitando el encofrado de tramos sucesivos de dicho muro, por lo que el conjunto debe ser desplazado en ascenso cada vez que el tramo de muro realizado ha alcanzado el fraguado suficiente. El armazón (4) está conectado a sendos largueros inferiores (5) y (6) mediante los tensores (7) y (8), constituyendo un conjunto guiado sobre la plataforma (2), por ejemplo, mediante ruedas (9) o similares.As depicted in the figures, the The present invention is applicable to a formwork assembly of vertical walls or structures (1), comprising conventional a work platform (2) that can remain associated with a second lower platform (3), both intended for personnel who carry out their work on these platforms, which are intended to support a movable frame (4) carrying one or several panels (12) intended for progressive wall formwork or vertical structure (1). The set of said platforms (2), (3) and frame (4) with the formwork panels (12) is incorporated on the wall (1) facilitating the formwork of successive sections of said wall, so the whole must be displaced in ascent every time the section of wall made has reached the setting enough. The frame (4) is connected to two stringers lower (5) and (6) by means of the tensioners (7) and (8), constituting a guided assembly on the platform (2), for example, by wheels (9) or similar.
El conjunto formado por los largueros (5) y (6) con sus guías, travesaños (no representados), etc., y el armazón (4) de soporte de los paneles de encofrado (12) es lo que se ha designado en esta descripción como "plataforma desplazable", que está montada sobre la plataforma fija (2).The set formed by the stringers (5) and (6) with its guides, crossbars (not shown), etc., and the frame (4) formwork panel support (12) is what has been designated in this description as "scrollable platform", which is mounted on the fixed platform (2).
El mecanismo objeto de la presente invención se compone, tal como se observa en las figuras, especialmente en las figuras 4 y 5, de un brazo principal o palanca de accionamiento (10) que está articulado sobre la estructura de la plataforma fija (2), mientras que, mediante un brazo auxiliar intermedio (13) está articulado al larguero (5) que forma parte de la plataforma móvil. El dispositivo de accionamiento indicado se repite para cada uno de los extremos del armazón (4), tal como se puede observar en la figura 1.The mechanism object of the present invention is composes, as seen in the figures, especially in the Figures 4 and 5, of a main arm or operating lever (10) which is articulated on the structure of the fixed platform (2), while, through an intermediate auxiliary arm (13) is articulated to the crossbar (5) that is part of the mobile platform. The indicated drive device is repeated for each of the ends of the frame (4), as can be seen in the Figure 1.
La disposición de los elementos constitutitos del dispositivo de accionamiento objeto de la invención permite que las posiciones extremas de la plataforma desplazable, es decir, las posiciones representadas en las figuras 3 y 5, que corresponden respectivamente a la posición de presionado del panel sobre la parte previamente realizada del muro (1) y a la posición de separación para permitir el paso de personal por la zona (14) intermedia entre el muro (1) y el panel de encofrado, correspondan a la posición completamente horizontal del brazo principal (10) del dispositivo, consiguiendo por lo tanto estabilidad y bloqueo en dichas posiciones, impidiendo el desplazamiento fortuito de la plataforma.The arrangement of constitutive elements of the drive device object of the invention allows the extreme positions of the movable platform, that is, the positions represented in figures 3 and 5, which correspond respectively to the position of pressing the panel on the part previously made of the wall (1) and to the separation position to allow the passage of personnel through the intermediate zone (14) between the wall (1) and the formwork panel correspond to the position completely horizontal of the main arm (10) of the device, thus achieving stability and blocking in said positions, preventing the accidental displacement of the platform.
El dispositivo se caracteriza por la disposición de un conjunto de palanca principal y un brazo auxiliar intermedio en correspondencia con la posición de cada una de las guías de la plataforma desplazable.The device is characterized by the arrangement of a main lever assembly and an intermediate auxiliary arm in correspondence with the position of each of the guides of the scrollable platform
Además, eventualmente cada uno de los conjuntos de brazo principal de accionamiento y brazo auxiliar intermedio se encuentra superpuesto a la correspondiente guía de la plataforma desplazable.In addition, eventually each of the sets of main drive arm and intermediate auxiliary arm are found superimposed on the corresponding platform guide scrollable
El brazo auxiliar intermedio (13) es ajustable en su longitud, especialmente por giro de su cuerpo sobre los extremos roscados, a efectos de posibilitar que la posición de trabajo representada en la figura 3 produzca el apriete previsto sobre el muro (1).The intermediate auxiliary arm (13) is adjustable in length, especially by turning your body over the threaded ends, in order to enable the position of work shown in figure 3 produce the expected tightening on the wall (1).
El brazo auxiliar intermedio tiene longitud ajustable y actúa como tensor.The intermediate auxiliary arm has length Adjustable and acts as a tensioner.
En la figura 6 se ha mostrado la variante según la cual el brazo principal (10) está articulado en la propia plataforma móvil y el brazo auxiliar (13) está articulado por su extremo inferior a la estructura fija (2), es decir, la estructura de soporte de dicha plataforma móvil. Esta versión podría ser utilizada en algunos casos para el accionamiento de la plataforma móvil si bien se considera preferible la versión descrita con respecto a las figuras 3 a 5.Figure 6 shows the variant according to which the main arm (10) is articulated in the own mobile platform and the auxiliary arm (13) is articulated by its lower end to the fixed structure (2), that is, the structure of support of said mobile platform. This version could be used in some cases to drive the platform mobile although the version described with with respect to figures 3 to 5.
En la gráfica representada en la figura 7 se muestra la multiplicación del esfuerzo, representado en ordenadas, a lo largo del ciclo completo de desplazamiento de la plataforma móvil y que se muestra en grados de giro del brazo principal, representado en abcisas. En efecto, dadas las características del dispositivo de la presente invención, el esfuerzo aplicado sobre el brazo principal del mecanismo se transmite a la plataforma móvil de manera amplificada. Esta relación de transmisión es variable en función de la posición del brazo principal. De este modo, en el inicio del movimiento, cuando es necesario vencer la adherencia de los paneles de encofrado con el hormigón así como la inercia, la relación de multiplicación del esfuerzo es muy elevada, permitiendo así que un esfuerzo no muy elevado por parte del operario que acciona el mecanismo, éste inicie el desplazamiento venciendo grandes resistencias. Por otro lado, en la parte intermedia del recorrido puede observarse en la figura 7 que la multiplicación del esfuerzo se reduce, pasando a una relación de transmisión más directa que permite un movimiento rápido de la plataforma móvil, aprovechando que las resistencias que se oponen al movimiento son menores una vez iniciado éste. Por último, en la zona final del ciclo de desplazamiento, se muestra en la figura 7 un nuevo aumento de la relación de multiplicación entre el esfuerzo aplicado sobre el brazo principal y el esfuerzo que el mecanismo ejerce sobre la plataforma móvil. Esta última característica viene a añadir una característica de seguridad del sistema pues sirve para obtener un efecto de bloqueo de desplazamiento accidental de la plataforma por acción del viento u otras causas fortuitas que puedan poner en peligro a los trabajadores que se encuentren en la zona (14) intermedia entre el muro (1) y el panel de encofrado.In the graph represented in figure 7, shows the multiplication of effort, represented in ordinates, throughout the complete platform displacement cycle mobile and shown in degrees of rotation of the main arm, Represented in abscissa. Indeed, given the characteristics of the device of the present invention, the effort applied on the main arm of the mechanism is transmitted to the mobile platform of amplified way. This transmission ratio is variable in function of the position of the main arm. Thus, in the beginning of the movement, when it is necessary to overcome the adherence of the formwork panels with concrete as well as inertia, the effort multiplication ratio is very high, allowing so an effort not very high by the operator that actuate the mechanism, it starts the movement by winning Great resistances On the other hand, in the middle part of the route can be seen in figure 7 that the multiplication of effort is reduced, moving on to a more transmission ratio direct that allows rapid movement of the mobile platform, taking advantage that the resistances that oppose the movement are minors once started this one. Finally, in the final zone of the displacement cycle, a new increase is shown in figure 7 of the multiplication relationship between the effort applied to the main arm and the effort that the mechanism exerts on the mobile platform This last feature comes to add a system security feature as it serves to obtain a blocking effect of accidental displacement of the platform by wind action or other fortuitous causes that may put in danger to workers in the area (14) intermediate between the wall (1) and the formwork panel.
Si bien la invención se ha representado y descrito con respecto a un ejemplo de realización, se debe comprender que la misma no queda limitada a dicha realización y que cualesquiera variaciones quedarán dentro del ámbito de la presente invención si quedan incluidas de las reivindicaciones adjuntas. De modo específico, el dispositivo de accionamiento para plataformas podría ser aplicado a otras plataformas no destinadas a la construcción.While the invention has been represented and described with respect to an exemplary embodiment, it should be understand that it is not limited to said embodiment and that any variations will be within the scope of this invention if included in the appended claims. From specific mode, the platform drive device could be applied to other platforms not intended for building.
