Description

ESTRUCTURA DE SOPORTE PARA ENCOFRADO DE MUROS STRUCTURE OF SUPPORT FOR WRAPPING OF WALLS
DESCRIPCIÓNDESCRIPTION
La presente invención se refiere a una estructura de soporte para encofrado de muros de tipo suspendido, que permite conseguir sensibles ventajas con respecto a lo actualmente conocido.The present invention relates to a support structure for formwork of walls of suspended type, which allows achieving sensible advantages with respect to what is currently known.
Las estructuras suspendidas para encofrado de muros están destinadas a facilitar los medios para que los operarios que efectúan el encofrado puedan ir realizando sus labores a medida que el muro está siendo construido, aumentando su altura. En caso de muros de gran altura se utilizan estructuras de tipo doble que permiten conseguir alturas elevadas de manipulación del encofrado. Dichas estructuras presentan, aparte de su plataforma de trabajo o "consola" superior, una prolongación importante en la parte inferior o segunda "consola", permitiendo efectuar trabajos en tramos del muro situados por debajo de la plataforma de trabajo. Sin embargo, este tipo de estructuras adolecen de un problema principal debido a sus grandes dimensiones que dificultan el montaje de la estructura en la obra mediante grúas de elevación, sobre todo en la fase inicial de levantamiento de la estructura del suelo, donde se habrá montado, hasta su colocación para el inicio del trabajo de la misma. Dada la envergadura de la estructura con consola doble, la operación de levantamiento resulta complicada por la falta de suficiente rigidez transversal de dicha estructura, que está destinada simplemente a su acoplamiento por suspensión a la pared que se irá hormigonando de manera gradual .Suspended structures for wall formwork are intended to provide the means for the workers who make the formwork to carry out their work as the wall is being built, increasing its height. In the case of high-rise walls, double-type structures are used to achieve high heights of formwork handling. Said structures have, apart from their work platform or upper "console", an important prolongation in the lower part or second "console", allowing work in sections of the wall located below the work platform. However, this type of structure suffers from a main problem due to its large dimensions that make it difficult to assemble the structure in the work by means of lifting cranes, especially in the initial phase of lifting the structure of the ground, where it will be mounted , until its placement for the start of the work of the same. Given the size of the structure with double console, the lifting operation is complicated by the lack of sufficient transverse stiffness of said structure, which is simply intended for its suspension coupling to the wall that will gradually be concreted.
La presente invención está destinada asimismo a cubrir importantes aspectos de seguridad de las consolas dobles actualmente conocidas, puesto que en éstas, al alcanzar alturas sensibles, del orden de los 6 metros, la parte de la estructura que queda por debajo de la plataforma de trabajo presenta por si misma problemas de seguridad para los operarios que deben trabajar en ella y que eventualmente se tienen que desplazar desde la plataforma de trabajo a la plataforma inferior mencionada, puesto que una altura del orden de los 6 metros puede representar peligros en caso de caidas del personal. Para solucionar los problemas anteriormente señalados, la presente invención se basa en constituir la parte de la estructura situada por debajo de la plataforma de trabajo mediante varios tramos de altura más reducida, por ejemplo, 2 metros, situando en cada uno de ellos una plataforma de trabajo auxiliar y constituyendo dichos tramos de forma articulada entre si, de manera que la parte posterior de cada tramo, es decir, la adyacente al muro en construcción, que lleva fijada la plataforma de trabajo auxiliar, estará articulada por los dos extremos, superior e inferior, mientras que la parte frontal de cada tramo se encontrará en una primera fase, desmontada por su parte inferior y articulada por su parte superior, permitiendo asi el libre movimiento y adaptación del conjunto de la estructura en la fase de levantamiento desde la posición horizontal para pasar a la posición vertical o de suspensión. Una vez en posición vertical se fijarán solidariamente los extremos inferiores de los elementos frontales de cada tramo de la estructura, dando rigidez al conjunto y dejando' la estructura con consola doble en disposición de trabajo normal, con una plataforma de trabajo principal y varias plataformas auxiliares, preferentemente tres, una para cada uno de los tramos inferiores con una altura aproximada de 2 metros.The present invention is also intended for cover important aspects of security of the double consoles currently known, since in these, when reaching sensitive heights, in the order of 6 meters, the part of the structure that lies below the work platform presents itself security problems for operators who must work on it and who eventually have to move from the work platform to the lower platform mentioned, since a height of the order of 6 meters can represent dangers in case of personnel falls. To solve the aforementioned problems, the present invention is based on constituting the part of the structure located below the work platform by several sections of lower height, for example, 2 meters, placing in each of them a platform of auxiliary work and constituting said sections in an articulated manner with each other, so that the rear part of each section, that is, the one adjacent to the wall under construction, which bears the auxiliary work platform, will be articulated by the two ends, upper and lower. lower, while the front part of each section will be in a first phase, disassembled by its lower part and articulated by its upper part, thus allowing the free movement and adaptation of the structure as a whole in the lifting phase from the horizontal position to move to the vertical or suspension position. Once upright the lower ends of the front elements of each section of the structure is integrally fixed, giving rigidity to the assembly and allowing 'structure with double console normal working arrangement with a working platform main and several auxiliary platforms, preferably three, one for each of the lower sections with an approximate height of 2 meters.
En una forma de realización preferente de la invención la parte superior de la consola, que soporta los paneles de encofrado, será desplazable para que el conjunto de los paneles de encofrado pueda desplazarse hacia atrás, separándose de la parte de la pared ya fraguada, y hacia adelante, para ocupar la posición de trabajo. También serán desplazables dichos paneles de encofrado verticalmente, a efectos de ajuste de su posición de trabajo.In a preferred embodiment of the invention, the upper part of the console, which supports the shuttering panels, will be movable so that the set of the shuttering panels can move backwards, separating from the part of the wall already set, and forward, to occupy the work position. These shuttering panels will also be vertically displaceable, for the purpose of adjusting their working position.
Para su mejor comprensión se adjuntan, a titulo de ejemplo, unos dibujos explicativos pero no limitativos de una realización preferente de la presente invención.For better understanding, explanatory but non-limiting drawings of a preferred embodiment of the present invention are attached, by way of example.

La figura 9 muestra una detalle de la disposición de medios para efectuar el ajuste del panel de encofrado en sentido vertical y en sentido horizontal.Figure 9 shows a detail of the arrangement of means for effecting the adjustment of the shuttering panel in a vertical direction and in a horizontal direction.
Tal como se representa en las figuras, la estructura de soporte para encofrado de muros según la presente invención comprende un módulo superior -1- portador de los tableros -2- para encofrado del muro y una plataforma de trabajo -3- asi como mástiles -4- para pasamanos de protección, prolongándose dicho módulo inferiormente en varios tramos o módulos articulados entre si dispuestos uno a continuación del otro, tales como los indicados con los numerales -5-, -6- y -7-, cada uno de los cuales tendrá una altura aproximada de 2 metros y presentará una plataforma de trabajo auxiliar, indicadas respectivamente con los numerales -8-, -9- y -10-. El conjunto de la estructura está destinado a su suspensión en el muro a medida que lo permita su fraguado. Para ello se fijarán anclajes, por ejemplo -11- y -12- en el muro, permitiendo efectuar la suspensión de la estructura de dichos anclajes.As shown in the figures, the support structure for wall formwork according to the present invention comprises an upper module -1- carrier of the panels -2- for wall formwork and a work platform -3- as well as masts - 4- for protection handrails, said module being extended inferiorly in several articulated sections or modules arranged one after the other, such as those indicated with the numerals -5-, -6- and -7-, each of which will have an approximate height of 2 meters and will present an auxiliary work platform, indicated respectively with the numerals -8-, -9- and -10-. The whole of the structure is intended to be suspended in the wall as its setting permits. For this, anchors will be fixed, for example -11- and -12- in the wall, allowing the suspension of the structure of said anchors.
De acuerdo con la invención, los tramos de estructura o módulos -5-, -6- y -7- tienen una altura predeterminada para evitar riesgos en las caldas, por ejemplo, unos 2 metros, para conseguir una mayor seguridad dentro de cada tramo, puesto que la altura de cada uno de ellos no representa ningún especial peligro para el personal ante la eventualidad de una caida, tal como ocurre con los tramos actuales que llegan a 6 metros.According to the invention, the sections of structure or modules -5-, -6- and -7- have a predetermined height to avoid risks in the bricks, for example, about 2 meters, to achieve greater security within each section, since the height of each of them does not represent any special danger for the staff in the event of a fall, as occurs with the current sections that reach 6 meters.
Para permitir un fácil levantamiento de la estructura desde el suelo, una vez formada la estructura en su conjunto, como minimo los módulos -6- y -7- están articulados con las plataformas anterior y posterior que les corresponden. De esta manera, la estructura puede ser levantada simplemente mediante una grúa, articulándose entre si dichos módulos. La fijación de los elementos frontales de cada módulo se efectúa después del posicionado vertical de la estructura, tal como se explicará a continuación con más detalle.To allow easy lifting of the structure from the ground, once the structure as a whole is formed, at least the modules -6- and -7- are articulated with the corresponding front and rear platforms. In this way, the structure can be lifted simply by means of a crane, said modules articulating with each other. The fastening of the front elements of each module takes place after the vertical positioning of the structure, as will be explained in more detail below.
Cada uno de los módulos -5-, -6- y -7- está constituido en forma de una especie de jaula, que en el caso del módulo -5- está constituida por un minimo de dos elementos extremos tal como el representado en la figura 1, formado por un brazo posterior -13- que quedará adyacente al muro, un brazo frontal -14- en oposición al muro y el soporte -15- para la plataforma principal o de trabajo y el soporte inferior -8- para una plataforma auxiliar. El brazo -14- llevará soportes -16- y -17-, en número variable, para la incorporación de pasamanos de protección. El módulo superior -1- presenta un armazón -18- de soporte del tablero o tableros de encofrado -2-, siendo dicho armazón -18- basculante con respecto a un punto de giro inferior por acción de un tirante ajustable -19- incorporado entre el soporte -15- y el mencionado armazón -18-. De esta manera, se posibilita la separación fácil del conjunto de los paneles de encofrado -2- con respecto al muro ya fraguado para iniciar un nuevo ciclo de elevación de la estructura de soporte de los tableros de encofrado a una posición más elevada. El armazón -18-, junto con los tableros -2-, podrá ser desplazado verticalmente y horizontalmente para su colocación vertical precisa, permitiendo el eventual solapado con el muro ya construido y asimismo conseguir un presionado suficiente para lograr estanqueidad en la parte inferior de los tableros de encofrado, enfrentados a la parte de muro ya fraguado. Ello se puede apreciar en las figuras y en particular en la figura 9, en la que se observa el husillo roscado de desplazamiento horizontal y de apriete -30-, que es susceptible de desplazar horizontalmente y presionar el tablero de encofrado -2-, que presenta la placa vertical -31-, para su acoplamiento frontal a la parte adyacente al borde superior del muro de hormigón -32-. La disposición mostrada en la figura consigue una correcta estanqueidad para evitar fugas en el vertido del hormigón.Each of the modules -5-, -6- and -7- is constituted in the form of a kind of cage, which in the case of the module -5- is constituted by a minimum of two end elements such as that represented in FIG. figure 1, formed by a rear arm -13- that will be adjacent to the wall, a front arm -14- as opposed to the wall and the support -15- for the main or work platform and the lower support -8- for a platform assistant. The arm -14- will carry supports -16- and -17-, in variable number, for the incorporation of protection handrails. The upper module -1- has a support frame -18- of the board or formwork panels -2-, said frame -18- being tiltable with respect to a lower pivot point by the action of an adjustable brace -19- incorporated between the support -15- and said frame -18-. In this way, the easy separation of the set of the shuttering panels -2- is possible with respect to the wall already set to start a new cycle of lifting the supporting structure of the shuttering panels to a higher position. The frame -18-, together with the boards -2-, can be moved vertically and horizontally for its precise vertical placement, allowing the possible overlap with the already built wall and also getting a sufficient pressure to achieve tightness in the lower part of the walls. formwork boards, facing the wall part already set. This can be seen in the figures and in particular in Figure 9, which shows the threaded spindle horizontal displacement and tightening -30-, which is capable of horizontally moving and press the formwork board -2-, which presents the vertical plate -31-, for its frontal coupling to the part adjacent to the upper edge of the concrete wall -32-. The arrangement shown in the figure achieves a correct seal to prevent leaks in the pouring of concrete.
El desplazamiento vertical se consigue mediante el husillo vertical -33-, que permite el desplazamiento vertical del tablero de encofrado -2- y placa frontal -31- para conseguir la posición deseada de altura.The vertical displacement is achieved by the vertical spindle -33-, which allows the vertical movement of the formwork board -2- and front plate -31- to achieve the desired height position.
En la figura 1 se han numerado y descrito todos los elementos más importantes de los diferentes módulos que configuran la estructura según una vista en alzado lateral. Se debe comprender, no obstante, que dichos módulos adoptan estructura de jaulas tridimensionales tal como se representan en el resto de vistas, especialmente en las figuras 2 y 3, en - las que se han dispuesto los mismos numerales que en la figura 1, con numerales en designación prima para los elementos en disposición simétrica en cada módulo. Asi, por ejemplo, se han representado los brazos posteriores del módulo -5-, -13- y -13'-, brazos frontales -14- y -14'-, tirantes de ajuste de posición -19- y -19'-, etc.In figure 1 all the most important elements of the different modules that make up the structure according to a side elevation view have been numbered and described. It should be understood, however, that said modules adopt structure of three-dimensional cages as they are represented in the rest of the views, especially in figures 2 and 3, in which the same numerals as in figure 1 have been arranged, with numerals in prime designation for elements in symmetrical arrangement in each module. Thus, for example, the arms have been represented rear of the module -5-, -13- and -13'-, front arms -14- and -14'-, position adjustment braces -19- and -19'-, etc.
En las figuras 4, 5, 6, 7 y 8 se aprecian detalles de construcción de una de los elementos del módulo -5-, es decir, del primer módulo situado por debajo del soporte -15- de la plataforma. La realización concreta de uno de los elementos del módulo -5- comprende travesanos de soporte -8- y -15-, respectivamente para una plataforma auxiliar y para la plataforma principal de trabajo asi como un brazo vertical posterior -13- y un brazo frontal -14- portador de los soportes -16- y -17- para elementos de barandilla de protección. En una versión preferente, los elementos -8-, -13-, -14- y -15- están unidos rígidamente entre sí con un tirante de refuerzo en forma de barra -20-, formando un marco resistente que con la disposición de las correspondientes plataformas y elementos de barandilla formará, junto con otro elemento simétrico en el otro extremo de la estructura de soporte de encofrado, el elemento modular con estructura general de jaula -5-, que es el primero por debajo de la plataforma de trabajo. El elemento horizontal -8- se prolonga por el lado adyacente al muro en un saliente -21- de tope con el muro, complementándose con otro saliente -22- a la altura de la fijación del tirante -20- y un tercer saliente superior -23- que es prolongación del travesano de soporte -15- y una placa inferior de refuerzo -24- portadora de una ranura en forma de ángulo -25- con el vértice redondeado dirigido hacia arriba, portadora de un pasador -26- que en un extremo de la ranura impide el desmontaje fortuito de la estructura de soporte del encofrado, mientras que en el otro extremo permite el desplazamiento vertical libre de la estructura para ocupar otra posición a mayor altura.Figures 4, 5, 6, 7 and 8 show construction details of one of the elements of the module -5-, that is, of the first module located below the support -15- of the platform. The specific embodiment of one of the elements of the module -5- comprises support crossings -8- and -15-, respectively for an auxiliary platform and for the main working platform as well as a vertical rear arm -13- and a front arm -14- carrier of the supports -16- and -17- for elements of guardrail. In a preferred embodiment, the elements -8-, -13-, -14- and -15- are rigidly joined to each other with a reinforcing rod-shaped bar -20-, forming a resistant frame that with the arrangement of the corresponding platforms and railing elements will form, together with another symmetrical element at the other end of the formwork support structure, the modular element with general cage structure -5-, which is the first below the work platform. The horizontal element -8- is extended on the side adjacent to the wall in a shoulder -21- of the wall, complementing with another projection -22- at the height of the fixation of the tie -20- and a third superior projection - 23- which is a prolongation of the support crossbar -15- and a lower reinforcing plate -24- carrying an angle-shaped groove -25- with the rounded apex directed upwards, carrying a pin -26- which in a The end of the slot prevents accidental disassembly of the support structure of the formwork, while at the other end allows free vertical movement of the structure to occupy another position at a higher height.
El travesano -15- es portador del puntal -4- para soporte de los elementos de barandilla, de manera que dicho puntal -4- está montado de forma articulada sobre dicho travesano -15-, presentando dos posiciones estables, una de ellas la representada en las figuras 4 y 5 para permitir el funcionamiento de los puntales -4- como soportes de los elementos de barandilla y otra posición de rebatimiento que se explicará en base a las figuras 6, 7 y 8, que facilita el transporte y almacenamiento.The crosspiece -15- carries the strut -4- to support the railing elements, so that said strut -4- is mounted in an articulated manner on said crosspiece -15-, having two stable positions, one of which is represented in figures 4 and 5 to allow the operation of the struts -4- as supports for the railing elements and another folding position that will be explained based on figures 6, 7 and 8, which facilitates transport and storage.
En las figuras 6 y 7 está representado el elemento para un módulo con una altura más reducida del brazo vertical -13-. Sin embargo, el carácter plegable de los puntales -4- portadores de los elementos de barandilla es igualmente válido para esta versión de brazo corto o para la versión de brazo largo mostrado en las otras figuras 1 a 5. En la realización mostrada, el puntal -4- queda articulado sobre un pasador -27- y tiene un segundo orificio cerca de su extremo con un segundo pasador -28- que es susceptible de quedar dispuesto tal como se muestra en la figura 8, para la posición de rebatimiento, o bien puede ser dispuesto atravesando el orificio -29- situado cerca del extremo del travesano -15-, inmovilizando verticalmente a dicho brazo -A- tal como es de ver en la figura 7. Los módulos inferiores -6- y -7- son articulados, quedando constituidos por brazos posteriores -35- y -36- y brazos frontales -38- y -39-, articulados por sus extremos, tal como se ha representado y las plataformas auxiliares -8-, -9- y -10-. Tal como se ha indicado anteriormente, la estructura de soporte de encofrado para muros quedará suspendida de los anclajes fijados en el propio muro, para lo cual los extremos adyacentes de la estructura son portadores de placas con alojamientos para los mencionados anclajes. En la figura 5 se ha representado una de dichas placas -34- dotada de una abertura -35-, cuya boca está dirigida hacia abajo y está destinada a coincidir en los anclajes previamente fijados en el muro, para la suspensión de la estructura de soporte de encofrados.In figures 6 and 7 is represented the element for a module with a lower height of the vertical arm -13-. However, the folding nature of the struts -4- carrying the guardrail elements is equally valid for this short arm version or for the long arm version shown in the other figures 1 to 5. In the embodiment shown, the strut -4- is articulated on a pin -27- and has a second hole near its end with a second pin -28- which is capable of being arranged as shown in figure 8, for the retraction position, or it can be arranged through the hole -29- located near the end of the crossbar -15-, vertically immobilizing said arm -A- as it is seen in figure 7. The lower modules -6- and -7- are articulated, being formed by rear arms -35- and -36- and front arms -38- and -39-, articulated at their ends, as shown and the auxiliary platforms -8-, -9- and -10-. As indicated above, the The support structure of the shuttering for walls will be suspended from the anchors fixed in the wall itself, for which the adjacent ends of the structure are carriers of plates with housings for the mentioned anchors. Figure 5 shows one of said plates -34- provided with an opening -35-, whose mouth is directed downwards and is intended to coincide in the anchors previously fixed in the wall, for the suspension of the support structure of formwork.
Se comprenderá que muchos de los elementos que se han descrito en las figuras mostradas a titulo de ejemplo se refieren a elementos individuales pero que, tal como se representa con claridad sobre todo en las figuras 2 y 3, la estructura es tridimensional, existiendo un mínimo de dos elementos para soporte de las plataformas, fijación y anclaje de las mismas.It will be understood that many of the elements that have been described in the figures shown by way of example refer to individual elements but that, as clearly represented above all in figures 2 and 3, the structure is three-dimensional, with a minimum of two elements to support the platforms, fixing and anchoring them.
Mediante la estructura para encofrados que se ha dado a conocer se posibilita una construcción sencilla y rápida de la estructura, pudiendo ser levantada de manera segura mediante una grúa, completando la fijación de algunas de las partes articuladas después del levantamiento parcial de la estructura, evitando los inconvenientes actualmente existentes.Thanks to the structure for formwork that has been made known, a simple and quick construction of the structure is possible, being able to be lifted safely by means of a crane, completing the fixing of some of the articulated parts after the partial lifting of the structure, avoiding the existing problems.
