Description

Dispositivo de anclaje para columnas de andamiaje.Anchoring device for columns of scaffolding.

Object of the invention

La presente invención se refiere a un dispositivo de anclaje, que ha sido especialmente concebido para las columnas o mástiles que, debidamente fijadas a la fachada o estructura de un edificio, permiten la movilización en altura a lo largo de dichas columnas de un andamio o plataforma de trabajo.The present invention relates to a device anchor, which has been specially designed for columns or masts that, duly fixed to the facade or structure of a building, allow the mobilization in height along these columns of a scaffold or work platform.

El objeto de la invención es conseguir que dicho dispositivo de anclaje no cubra apenas superficie alguna sobre la fachada, permitiendo dejar prácticamente terminada esta última, y que además sea capaz de absorber posibles irregularidades en la fachada, al objeto de conseguir un perfecto aplome en las columnas o mástiles.The object of the invention is to ensure that said anchoring device does not just cover any surface on the facade, allowing the latter to be practically finished, and that is also able to absorb possible irregularities in the facade, in order to achieve a perfect poise in the columns or masts.

Background of the invention

A la hora de realizar trabajos sobre la fachada de un edificio, una de las soluciones conocidas consiste en disponer ante dicha fachada de uno o más mástiles o columnas, de altura apropiada, que constituyen guías para desplazamiento vertical del andamio o plataforma de trabajo sobre la que se cargan los materiales y los operarios para trabajar sobre la fachada, de manera que con medios debidamente motorizados la citada plataforma es susceptible de ascender/descender por las columnas, y de estabilizarse a cualquier nivel en altura adecuado.When performing work on the facade of a building, one of the known solutions consists of have before said facade one or more masts or columns, of appropriate height, which constitute guides for displacement vertical scaffolding or work platform on which they are loaded materials and operators to work on the facade, of so that with duly motorized means the said platform it is capable of ascending / descending through the columns, and of stabilize at any level at adequate height.

Para que la estructura descrita sea estable las columnas se fijan a la fachada o estructura del edificio en puntos adecuadamente distanciados, con la colaboración de robustas placas ahorquilladas, provistas en su base o rama media de una pareja de orificios a través de los que dicha placa se fija a la pared mediante una pareja de robustos tornillos y respectivos tacos metálicos de expansión.For the described structure to be stable the columns are fixed to the facade or structure of the building in points properly distanced, with the collaboration of robust plates bracketed, provided at its base or middle branch of a couple of holes through which said plate is fixed to the wall through a pair of robust screws and respective dowels metallic expansion.

Esta solución presenta una problemática con una doble vertiente, por un lado las citadas placas cubren áreas importantes de la fachada, de manera que tras el desmontaje del andamio es preciso retocar la superficie de dicha fachada en todas las áreas en las que había estado situada una placa, y por otro lado, dado que dichas placas quedan fija e íntimamente unidas a la fachada, cualquier irregularidad de esta última repercute negativamente en el correcto aplome de la columna asociada a las mismas.This solution presents a problem with a double slope, on the one hand the aforementioned plates cover areas important façade, so that after dismantling the scaffolding is necessary to touch up the surface of said facade in all the areas in which a plaque had been located, and on the other side, given that said plates are fixed and intimately attached to the facade, any irregularity of the latter has repercussions negatively in the correct aplome of the column associated with the same.

Description of the invention

El dispositivo de anclaje que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los dos aspectos comentados.The anchoring device that the invention proposes to solve the problem fully satisfactorily previously exposed, in the two aspects commented.

Para ello y de forma más concreta, dicho dispositivo viene a sustituir a cada uno de los clásicos tornillos y tacos de expansión convencionales, y más concretamente al tornillo propiamente dicho, ya que como taco de expansión se puede seguir utilizando un taco de expansión convencional, centrándose la invención específicamente en el tornillo que completa dicho taco, que en lugar de incorporar tan sólo un sector roscado rematado en la correspondiente cabeza, incorpora al otro lado de dicha cabeza un segundo sector roscado, de mayor longitud que el primero, sobre el que a su vez se monta una pareja de tuercas que son las que fijan a la placa anteriormente citada. De esta manera se consiguen dos efectos, en primer lugar la placa soporte de las columnas queda sustancialmente distanciada de la fachada y se puede trabajar tras la misma, sin perjuicio de la solidez en el anclaje, y por otro lado y merced a la pareja de tuercas anteriormente citadas se puede regular a voluntad el posicionamiento de la placa con respecto al vástago roscado, o lo que es lo mismo, se puede regular el distanciamiento exacto de la placa con respecto al plano de fachada, para que el aplome de la columna sustentadora del andamiaje sea perfecto.To do this and more specifically, said device comes to replace each of the classic screws and conventional expansion plugs, and more specifically when screw itself, since as an expansion plug you can continue using a conventional expansion plug, focusing the invention specifically in the screw that completes said block, that instead of incorporating only a threaded sector finished off in the corresponding head incorporates on the other side of said head a second threaded sector, longer than the first, on which in turn mounts a pair of nuts that are the ones that fix to the aforementioned plate. This way you get two effects, first the column support plate is substantially distanced from the facade and can be worked after the same, notwithstanding the strength in the anchor, and on the other side and thanks to the pair of nuts mentioned above you can regulate at will the positioning of the plate with respect to the threaded rod, or what is the same, you can regulate the exact distance of the plate from the plane of facade, so that the aplome of the supportive column of the scaffolding be perfect

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como el dispositivo de anclaje que la invención propone está constituido a partir de un doble tornillo, representado en detalle en la figura 1, en el que participa una cabeza poligonal e intermedia (1), a partir de la cual se define, en un sentido un tramo roscado (2) o primer tornillo, equivalente a un tornillo convencional de los utilizados en tacos de expansión metálicos, como los tacos (3) que aparecen representados en la figura 3, mientras que al otro lado de la citada cabeza (1) se establece un vástago roscado (4), de longitud considerablemente mayor que la del sector roscado (2), cuya métrica puede ser igual o diferente, y que en cualquier caso está destinado a recibir a una pareja de tuercas (5), preferentemente asistidas por respectivas arandelas (6), que situándose a ambos lados de la clásica placa (7) con su horquilla (8) para fijación de la columna del andamiaje, no representada, permiten una rígida fijación de dicha placa (7) a la estructura del edificio, como por ejemplo al borde frontal del forjado (9) representado en la figura 2.In view of the figures outlined you can be observed as the anchoring device that the invention proposes it is constituted from a double screw, represented in detail in figure 1, in which a polygonal head e intermediate (1), from which it is defined, in a sense a threaded section (2) or first screw, equivalent to a screw conventional of those used in metal expansion plugs, such as the studs (3) shown in figure 3, while that on the other side of said head (1) a rod is established threaded (4), of length considerably greater than that of the sector threaded (2), whose metric may be the same or different, and that in Any case is intended to receive a couple of nuts (5), preferably assisted by respective washers (6), which standing on both sides of the classic plate (7) with its fork (8) for fixing the scaffolding column, not shown, allow a rigid fixation of said plate (7) to the structure of the building, such as the front edge of the floor (9) represented in figure 2.

Esto permite que la fijación de la placa (7), además de ser sólida y eficaz, se produzca en situación de notable distanciamiento con respecto al frente de la estructura (9), lo que permite manipulaciones sobre dicho frente que sólo se ven entorpecidas por los vástagos roscados (4) y que permiten un acabado casi total de la fachada, puesto que tras el desmontaje del andamio, y consecuentemente tras el desmontaje también de los tacos de expansión (3), tan sólo es necesario proceder a obturar los orificios dejados por los mismos, de incidencia mínima en el contexto general de dicha fachada.This allows plate fixation (7), In addition to being solid and effective, it occurs in a situation of remarkable distancing from the front of the structure (9), which it allows manipulations on that front that can only be seen hindered by the threaded rods (4) and which allow a almost total finish of the facade, since after dismantling the scaffolding, and consequently after the removal of the studs expansion (3), it is only necessary to proceed to seal the holes left by them, with minimal impact on the general context of said facade.

Como también se deduce de la estructura descrita, la posibilidad de regular posicionalmente las tuercas (5) sobre vástagos roscados (4) permite a su vez regular el distanciamiento efectivo entre la placa (7) y la estructura (9) de edificio, de manera que con independencia de las irregularidades en el frontal de dicha estructura, las diferentes placas (7) correspondientes a los respectivos puntos de fijación de una columna o mástil, pueden quedar perfectamente alineadas y aplomadas.As it also follows from the structure described, the possibility of positionally adjusting the nuts (5) on threaded rods (4) allows in turn to regulate the distance effective between the plate (7) and the building structure (9), of so that regardless of the irregularities in the front of said structure, the different plates (7) corresponding to the respective fixing points of a column or mast, can Be perfectly aligned and plumb.

De acuerdo con la estructuración descrita, la operativa para la implantación del dispositivo de anclaje es la siguiente:According to the structuring described, the operational for the implantation of the anchoring device is the next:

Tras efectuar un orificio en el frente de la estructura (9), como por ejemplo en el borde del forjado, se introduce en el mismo el taco de expansión metálico (3) y se procede a la definitiva fijación del mismo, mediante expansión, actuando con una llave apropiada sobre la cabeza poligonal (1) del dispositivo, hasta una situación de rigidez estructural del conjunto equivalente a la mostrada en la figura 2.After making a hole in the front of the structure (9), such as on the edge of the floor, is insert the metal expansion plug (3) into it and proceeds to the definitive fixation of the same, through expansion, acting with an appropriate wrench on the polygonal head (1) of the device, up to a situation of structural rigidity of the set equivalent to that shown in figure 2.

En ese momento se montan sobre la pareja de vástagos roscados (4) correspondientes a un mismo dispositivo, respectivas tuercas (5) con sus arandelas (6), distanciándolas de las cabezas (1) de los tornillos en una magnitud acorde con el distanciamiento previsto para la placa de fijación (7) y el imaginario plano frontal de la estructura.At that time they are mounted on the couple of threaded rods (4) corresponding to the same device, respective nuts (5) with their washers (6), distancing them from the heads (1) of the screws in a magnitude consistent with the planned spacing for the fixing plate (7) and the Imaginary frontal plane of the structure.

Seguidamente se acopla a los citados vástagos roscados (4) la placa (7), a través de sus clásicos orificios (10), rasgados perpendicularmente el uno con respecto al otro, para permitir absorber posibles y ligeros errores en los orificios practicados sobre la estructura (9), y finalmente se procede al montaje y apriete del otro juego de tuercas (5) con sus arandelas (6), lo que genera el definitivo apriete y fijación de la placa (7) a los vástagos roscados (4), y consecuentemente y a través de estos últimos a la propia estructura (9) del edificio, con un acusado distanciamiento de la placa (7) con respecto a dicho frente (9) de la estructura y con una posibilidad de regular a voluntad dicho distanciamiento dentro de unos márgenes sobradamente suficientes, como para permitir un perfecto aplome de las diferentes placas (7), como repetidamente se ha dicho.It is then coupled to the aforementioned stems threaded (4) the plate (7), through its classic holes (10), torn perpendicularly to each other, to allow to absorb possible and slight errors in the holes practiced on the structure (9), and finally we proceed to assembly and tightening of the other set of nuts (5) with their washers (6), which generates the definitive tightening and fixing of the plate (7) to the threaded stems (4), and consequently and through these last to the building's own structure (9), with a defendant distance from the plate (7) with respect to said front (9) of the structure and with a possibility of regulating at will said distancing within excessively sufficient margins, as to allow a perfect aplome of the different plates (7), as repeatedly said.
