Description
Útil para desmontaje de soportes para encofrados de piso.Useful for disassembly of formwork supports of floor.
La presente invención está destinada a dar a conocer un útil para el desmontaje de soportes para encofrados de piso que presenta originales características que justifican su novedad y actividad inventiva.The present invention is intended to give know a tool for the disassembly of supports for formwork floor that presents original characteristics that justify its Novelty and inventive activity.
Los encofrados para pisos comprenden habitualmente vigas apoyadas en puntales, cuyas vigas llevan asociados soportes desmontables que a su vez proporcionan los bordes de soporte de los paneles de encofrado planos propiamente dichos.Floor formwork comprises usually beams supported on struts, whose beams carry associated removable brackets that in turn provide the support edges of the flat formwork panels properly sayings
Como es sabido, se utilizan dichos soportes de los paneles de encofrado con carácter desmontable para que después de un periodo relativamente corto de fraguado del hormigón que constituye el piso se puedan desmontar los paneles de encofrado, puesto que el hormigón armado ya es suficientemente resistente para resistir su propio peso. Para ello los soportes desmontables presentan mecanismos, tales como cerrojos de diferentes tipos que permiten su montaje y desmontaje más o menos fáciles. Sin embargo presentan un problema sensible en su desmontaje por el hecho de que al ser su peso considerable y la altura de manipulación asimismo de cierta consideración, su desmontaje manual puede presentar problemas desde el punto de vista del tiempo necesario para la operación y de que sea suficiente la seguridad para los operarios. En efecto, para una operativa segura es necesario disponer de los medios apropiados para cada soporte para que los operarios puedan montar y desmontar dichos soportes y bajar los mismos a nivel de suelo, eventualmente con ayuda de una persona ayudante. En la práctica y a efectos de mayor rapidez de la operación, muchos operarios efectúan dicha operación de desmontaje en condiciones precarias que representan un riesgo para su seguridad o para la de otros operarios, dado que no efectúan adecuadamente la sujeción del soporte una vez desmontado y éste, con un peso considerable, puede caerse por lo que puede representar un sensible peligro para el personal.As is known, said supports are used formwork panels with removable character so that after of a relatively short period of concrete setting that constitutes the floor formwork panels can be disassembled, since reinforced concrete is already strong enough to Resist your own weight. For this, the removable brackets present mechanisms, such as locks of different types that they allow its assembly and disassembly more or less easy. But nevertheless they present a sensitive problem in their disassembly due to the fact that being its considerable weight and handling height also of some consideration, its manual disassembly may present problems from the point of view of the time needed for operation and that the safety for the operators is sufficient. Indeed, for a safe operation it is necessary to have the appropriate means for each support so that operators can assemble and disassemble these supports and lower them to the level of soil, eventually with the help of a helper. In the practice and for the purpose of faster operation, many operators carry out said disassembly operation in conditions precarious that represent a risk to your safety or to that of other operators, since they do not properly hold the support once disassembled and this one, with a considerable weight, can fall for what may represent a sensitive danger to the personal.
El útil objeto de la presente invención está destinado a solucionar los inconvenientes mencionados facilitando los medios para que un solo operario desde el suelo pueda efectuar con facilidad el desmontaje y descenso de los soportes para los paneles de encofrado con rapidez y sin peligro alguno.The useful object of the present invention is intended to solve the aforementioned problems by facilitating the means for a single operator from the ground to perform Easily disassemble and lower the supports for formwork panels quickly and without danger.
Para conseguir este objetivo, el útil objeto de la presente invención presenta un largo mango destinado a su asido por un operario y que en su parte superior presenta un terminal de percusión y una horquilla de suspensión, de manera que con el terminal de percusión el operario puede impulsar el cerrojo del soporte desmontable para provocar su desprendimiento con respecto a la viga en la que está montado y, mediante la horquilla situada por debajo, puede sujetar el soporte de manera segura, después de lo cual puede efectuar su descenso hasta el suelo.To achieve this goal, the useful object of The present invention has a long handle for gripping. by an operator and that in its upper part presents a terminal of percussion and a suspension fork, so that with the percussion terminal the operator can push the bolt of the detachable support to cause its detachment with respect to the beam on which it is mounted and, by means of the fork located by underneath, you can securely hold the bracket, after which can make its descent to the ground.
La construcción del útil es muy simple, consistiendo en un elemento central tubular que constituye el mango de accionamiento, el cual sirve además por su parte superior a efectos de percusión, para lo cual puede llevar soldada una pletina en ángulo u otro elemento similar y, la parte de la horquilla puede quedar constituida simplemente por un elemento de varilla doblado en forma de U con ganchos extremos que permiten sujetar el soporte desmontable de los paneles de encofrado por uno de sus largueros, lo cual implica la colocación de forma inclinada del soporte sobre la horquilla, lo que impide la caída del soporte, puesto que al quedar el centro de gravedad del mismo sensiblemente por debajo del punto de suspensión en la horquilla, resulta prácticamente imposible su desprendimiento fortuito.The construction of the tool is very simple, consisting of a tubular central element that constitutes the handle of actuation, which also serves in its upper part to percussion effects, for which a platen can be welded angled or other similar element and, the fork part can be constituted simply by a bent rod element U-shaped with extreme hooks that allow you to hold the support removable formwork panels by one of its stringers, what which implies the inclined placement of the support on the fork, which prevents the support from falling, since when remaining the center of gravity of it substantially below the point suspension on the fork, it is practically impossible to fortuitous detachment.
El elemento tubular o mango del útil podrá quedar realizado en múltiples formas que permitan un fácil manejo del mismo, tal como se ha explicado. En particular, podría quedar realizado en dos piezas, un mango propiamente dicho de un material más ligero, para facilitar la manipulación, y una parte superior que es la destinada a soportar el elemento de percusión, realizada en un tubo de acero. La unión entre los dos elementos puede tener lugar, por ejemplo, mediante tornillos u otro medio.The tubular element or handle of the tool may be made in multiple ways that allow easy handling of it, as explained. In particular, it could be made in two pieces, a handle itself of a material lighter, for easier handling, and a top that It is intended to support the percussion element, performed in A steel tube. The union between the two elements can have place, for example, by screws or other means.
Al propio tiempo, la pletina fijada en el extremo del mango a efectos de percusión puede tener también una sensible utilidad como palanca para el desplazamiento de paneles en el momento del desmontaje o para otros trabajos manuales en la obra.At the same time, the plate fixed on the end of the handle for percussion purposes can also have a sensitive utility as a lever for moving panels in the time of disassembly or for other manual work in the work.

Tal como se aprecia en las figuras, el útil objeto de la presente invención tendrá su aplicación en obras de hormigón armado en las que se desea construir un piso de hormigón (1) mediante paneles de encofrado soportados sobre vigas (2) mediante soportes desmontables (3) del tipo que se ha mostrado en mayor detalle en la figura 9. Las vigas quedan apoyadas sobre puntales (4) y los soportes (3) están dotados de cerrojos inferiores (7) que permiten su desmontaje fácil una vez que el piso de hormigón (1) ha fraguado suficientemente para resistir su propio peso, con lo que se procede a desmontar los soportes (3) y los paneles de encofrado dejando las vigas (2) en su lugar soportadas por los puntales (4) hasta conseguir el endurecimiento total del piso.As shown in the figures, the tool object of the present invention will have its application in works of reinforced concrete on which you want to build a concrete floor (1) by formwork panels supported on beams (2) by removable brackets (3) of the type shown in greater detail in figure 9. The beams are supported on struts (4) and supports (3) are provided with lower bolts (7) that allow easy disassembly once the floor of concrete (1) has set enough to resist its own weight, with which we proceed to disassemble the supports (3) and the formwork panels leaving the beams (2) in place supported by the struts (4) until total hardening of the floor.
Tal como se aprecia en más detalle en la figura 9, un soporte (3) comprende generalmente dos largueros (5) paralelos entre sí y unidos mediante puentes (6) presentando además un puente intermedio o cuerpo de cerrojo (7) para el acoplamiento del pestillo (8) desplazable en el sentido transversal del soporte (3). En una de sus posiciones el pestillo (8) solidariza el soporte (3) con una de las vigas (2), correspondiendo ésta a la posición de trabajo mientras que en otra posición del pestillo (8), es decir, una vez efectuado su desplazamiento axial, el cuerpo (7) del cerrojo queda liberado con respecto a la viga (2) y el conjunto del soporte (3) se puede desmontar, con lo que se pueden desmontar asimismo los paneles de encofrado.As can be seen in more detail in the figure 9, a support (3) generally comprises two stringers (5) parallel to each other and linked by bridges (6) also presenting an intermediate bridge or bolt body (7) for coupling of the latch (8) movable in the transverse direction of the support (3). In one of its positions the latch (8) supports the support (3) with one of the beams (2), this corresponding to the position of work while in another position of the latch (8), that is, once its axial displacement has been made, the body (7) of the bolt is released with respect to the beam (2) and the whole support (3) can be disassembled, which can be disassembled also the formwork panels.
En la operación de desmontaje se presenta, tal como se ha indicado, la dificultad de manipulación de los soportes, puesto que éstos tienen un peso considerable y se hallan a una altura que puede ser del orden de unos 3 metros, lo que presenta dificultades de manipulación por parte de los operarios y un claro peligro en caso de caída.In the disassembly operation is presented, such as indicated, the difficulty of handling the supports, since these have a considerable weight and are at a height that can be of the order of about 3 meters, which presents handling difficulties by operators and a clear danger in case of fall.
La presente invención está destinada a facilitar el desmontaje de los soportes (3) desde el piso inferior de manera que un operario pueda efectuar fácilmente dicho operación sin peligro. Para ello la presente invención prevé la realización de un útil constituido por un mango (9) de considerable longitud, de manera que el operario (12) pueda manejar dicho mango de pie en el suelo (13), de manera que dicho mango presente superiormente una zona de percusión (10) y una horquilla (11) de manera que el operario puede fácilmente impulsar el pestillo móvil (8) del cerrojo (7) permitiendo que el soporte quede liberado de la viga. Ello se ha representado en la figura 4, en la que el vector (14) representa el descenso del cuerpo (7) que forma parte del soporte y que quedará ensartado en la horquilla (11) tal como se ha representado en la figura 5.The present invention is intended to facilitate the disassembly of the supports (3) from the lower floor so that an operator can easily perform said operation without danger. For this, the present invention provides for the realization of a tool consisting of a handle (9) of considerable length, of so that the operator (12) can handle said foot handle in the floor (13), so that said handle has a superior percussion zone (10) and a fork (11) so that the operator can easily push the mobile latch (8) of the bolt (7) allowing the support to be released from the beam. This has been represented in Figure 4, in which the vector (14) represents the descent of the body (7) that is part of the support and which will be skewered on the fork (11) as it has been represented in figure 5.
Tal como se ha representado en las figuras, el útil presenta en la horquilla (11) dos brazos paralelos (18) los cuales presentan por sus extremos sendos ganchos (15). De este modo el soporte (3) que se desprende de la viga después de la percusión mediante la cabeza superior (10) del útil, queda ensartado en la horquilla (11) de manera que los ganchos (15) retienen uno de los largueros del soporte quedando éste suspendido como muestra la figura 8, en la que se aprecia que el posicionado del soporte, con su centro de gravedad por debajo del punto de suspensión, representa una posición estable de manera que no se puede desprender fortuitamente.As depicted in the figures, the tool presents in the fork (11) two parallel arms (18) the which present at their ends two hooks (15). In this way the support (3) that emerges from the beam after percussion through the upper head (10) of the tool, it is skewered in the fork (11) so that the hooks (15) retain one of the support stringers being suspended as shown in the Figure 8, which shows that the positioning of the support, with its center of gravity below the suspension point, represents a stable position so that it cannot be detached fortuitously.
En una realización simple el mango (9) del útil quedará constituido simplemente por un elemento tubular de acero de tipo comercial, presentando unida por soldadura la horquilla (11), realizada preferentemente mediante una varilla doblada en la que se constituyen los dos brazos paralelos (18) y los ganchos extremos (15), presentando la cabeza superior (10) del útil una zona de refuerzo para permitir la percusión del útil sobre el pasador o pestillo móvil (8) del cerrojo (7). Dicha cabeza (10) puede quedar reforzada mediante una simple pletina soldada en ángulo (17) u otro tipo de refuerzos.In a simple embodiment the handle (9) of the tool it will be constituted simply by a tubular steel element of commercial type, presenting by welding the fork (11), preferably made by a bent rod in which they constitute the two parallel arms (18) and the extreme hooks (15), the upper head (10) of the tool having an area of reinforcement to allow percussion of the tool on the pin or mobile latch (8) of the bolt (7). Said head (10) may remain reinforced by a simple angle welded plate (17) or other type of reinforcements.
El elemento tubular o mango (9) puede quedar realizado de múltiples formas que permitan la función a la que está destinado el útil. En particular, se podría prever una construcción tal como la representada en las figuras en la que el mango (9) quedará realizado en un material ligero, por ejemplo, una aleación de aluminio, mientras que la parte superior (16), que lleva el extremo de percusión preferentemente en forma de pletina (17), podrá quedar realizado en acero u otro material resistente. Al propio tiempo, al sobresalir la pletina (17) del mango (9) dando lugar a una uña o saliente, éste podrá ser utilizado fácilmente como palanca para despegar paneles o para otras finalidades.The tubular element or handle (9) can be performed in multiple ways that allow the function to which it is intended the tool. In particular, a construction could be provided as depicted in the figures in which the handle (9) it will be made of a lightweight material, for example, an alloy aluminum, while the upper part (16), which bears the percussion end preferably in the form of a plate (17), may be made of steel or other resistant material. To own time, when protruding the plate (17) of the handle (9) giving rise to a nail or projection, this can easily be used as a lever to take off panels or for other purposes.
Como se comprenderá, la invención ha sido descrita en base a un ejemplo de realización preferente que no es limitativa del alcance de la invención, de manera que los técnicos en la materia, después de conocer lo que se indica en la presente descripción y se muestra en los dibujos, podrán introducir diferentes variantes que podrán quedar incluidas dentro del ámbito de la presente invención si están comprendidas en el alcance de las reivindicaciones siguientes.As will be understood, the invention has been described based on a preferred embodiment that is not limiting the scope of the invention, so that technicians in the matter, after knowing what is indicated herein description and shown in the drawings, you can enter different variants that may be included within the scope of the present invention if they fall within the scope of the following claims.
