Description

Andamio perfeccionado.Improved scaffolding.

Objeto de la invenciónObject of the invention

La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a un andamio perfeccionado, el cual comporta notables ventajas respecto de los que existen en la actualidad y que pueden considerarse de su tipo.The present invention, as expressed by the set forth in this specification, refers to a scaffold perfected, which has significant advantages over the that exist today and that can be considered their kind.

Este tipo de andamios está formado por dos bastidores laterales arriostrados con tirantes de rigidización y que incluyen superiormente también una barandilla de seguridad para el usuario subido al tablón o tablero horizontal tendido entre dos travesaños parejos de los bastidores laterales.This type of scaffolding consists of two bracing side frames with stiffening braces and which also include a safety guardrail for the user uploaded to the plank or horizontal board lying between two even crossbars of the side frames.

Es un objeto de la invención el facilitar el montaje del andamio y también dotarle de elevada seguridad en los anclajes para que queden perfectamente bloqueados sin posibilidad de que se salga de forma fortuita cualquier elemento de armado.It is an object of the invention to facilitate the Scaffolding assembly and also provide high security in the anchors so that they are perfectly locked without possibility that any armed element is accidentally left.

Antecedentes de la invenciónBackground of the invention

En la actualidad los tirantes oblicuos que se montan entre los bastidores para el arriostramiento de éstos y estabilidad del andamio, están determinados por barras provistas de orificios por los que son entrantes respectivos bulones vinculados a los largueros de dichos bastidores laterales, evitándose después su salida mediante pasadores de aletas u otros dispositivos similares montados con este fin, lo que conlleva una labor complicada y desde luego un sistema de armado poco fiable.At present the oblique braces that are mounted between the racks for the bracing of these and stability of the scaffold, are determined by bars provided with holes through which respective bolts are incoming linked to the stringers of said side frames, then avoiding its exit through fin pins or other devices similar mounted for this purpose, which entails work complicated and of course an unreliable assembly system.

Descripción de la invenciónDescription of the invention

En líneas generales, el andamio perfeccionado que constituye el objeto de la presente invención, aún siendo del tipo formado por los dos bastidores laterales definidos por dos largueros verticales y varios travesaños horizontales tendidos entre ellos, tiene la particularidad de que estos últimos son tubulares y atraviesan los largueros para ofrecer sus embocaduras al exterior. En estas embocaduras penetran los tetones previstos ortogonalmente en los extremos de los tirantes oblicuos de rigidización del andamio, así como del tirante horizontal con función de barandilla, existiendo en estos extremos sendos soportes acodados articulados en los propios ejes geométricos que materializan dichos tetones, siendo susceptibles dichos soportes de abrazar parcialmente el larguero adyacente en una posición angular obtenida por gravedad, en tanto que para conseguir la extracción del tirante es necesario levantar angularmente el soporte para que el extremo acodado que abraza al larguero no se solape con él. De esta forma se consigue fácilmente la posición de seguro impidiendo la accidental salida del tirante.In general, the perfected scaffolding which constitutes the object of the present invention, even though it is the type formed by the two side frames defined by two vertical stringers and several horizontal crossbars laid among them, it has the peculiarity that the latter are tubular and cross the beams to offer their mouths to the Exterior. In these mouths penetrated the intended lugs orthogonally at the ends of the oblique braces of stiffening of the scaffolding, as well as the horizontal brace with railing function, existing in these ends two supports layered articulated in the geometric axes themselves that materialize said lugs, said supports being susceptible to partially embrace the adjacent stringer in an angular position obtained by gravity, while to achieve extraction of the brace it is necessary to raise the support angularly so that the angled end that hugs the crossbar does not overlap with it. From This way you easily get the safe position by preventing the accidental exit of the tie.

Por otra parte, el tablero móvil que se sitúa a la altura deseada, tendido entre dos travesaños parejos de los bastidores laterales, incluye en sus extremos dos pares de pletinas en "L" colaterales y solidarias a ellos de forma que presentan un ala libre dirigida hacia abajo haciendo tope sobre el exterior del travesaño correspondiente, inmovilizándose así linealmente el tablero.On the other hand, the mobile board that stands at the desired height, lying between two even crossbars of the side racks, includes at its ends two pairs of plates in "L" collateral and solidarity with them so that they present a free wing directed downwards butt on the outside of the corresponding crossbar, thus immobilizing the board.

Vinculados a cada una de estas pletinas en "L" está dispuesto un gatillo de bloqueo que es articulado al estar materializado por una palanca que oscila por uno de los extremos en un punto medio de la pletina en "L", cayendo su otro extremo por gravedad por la parte interior del travesaño correspondiente del bastidor lateral, teniendo inferiormente un diente que abraza parcialmente al aludido travesaño reteniéndole simplemente por gravedad.Linked to each of these plates in "L" is arranged a lock trigger that is articulated to the be materialized by a lever that oscillates through one of the ends at a midpoint of the "L" plate, dropping its other end by gravity on the inside of the crossbar corresponding to the side frame, having a lower tooth that partially hugs the aforementioned crossbar retaining it simply by gravity.

Para desmontar el tablero es necesario girar ligeramente el gatillo para zafar el diente y elevar el tablero.To disassemble the board it is necessary to turn slightly the trigger to release the tooth and raise the board.

Se ha previsto también que los bastidores laterales del andamio sean los tramos de una escalera extensible al incorporar en el extremo superior de uno de ellos las bridas o abrazaderas que sujetan los largueros del otro bastidor, contando este último inferiormente con los ganchos de conexión en el travesaño seleccionado del bastidor inferior o de apoyo en el suelo. El bastidor inferior cuenta además con una barra transversal con dos porciones en voladizo provistas de tacos extremos de apoyo en el suelo, para aumentar la seguridad de la escalera y gracias a la cual también se obtiene mayor seguridad en la posición de
andamio.
It is also provided that the scaffolding side frames are the stretches of an extendable ladder by incorporating at the upper end of one of them the flanges or clamps that hold the stringers of the other frame, the latter counting lowerly with the connection hooks in the crossbar selected from bottom frame or floor support. The lower frame also has a transverse bar with two cantilever portions provided with end-of-ground support tacos, to increase the safety of the ladder and thanks to which also greater security is obtained in the position of
scaffold.

Descripción de la forma de realización preferidaDescription of the preferred embodiment

Haciendo referencia a la numeración adoptada en las figuras, podemos ver cómo el andamio perfeccionado que la invención propone, está formado como se ve en la figura 1, por dos bastidores laterales (1) y (2) materializados por dos largueros (3) y varios travesaños (4) de estructura tubular. Ambos bastidores laterales (1) y (2) están debidamente arriostrados con los tirantes oblicuos (5) (en este ejemplo en número de dos y unidos articuladamente en forma de aspa) para alcanzar la estabilidad debida, y el tablero (6) tendido entre los bastidores laterales (1) y (2) descansando sobre los travesaños (4) seleccionados a la altura deseada. También existe un tirante horizontal (7) en la parte superior, que actúa como barandilla y que se sitúa siempre a cierta distancia de la posición que ocupe el tablero horizontal (6).Referring to the numbering adopted in the figures, we can see how the scaffolding perfected that the proposed invention, is formed as seen in figure 1, by two side frames (1) and (2) materialized by two stringers (3) and several crossbars (4) of tubular structure. Both racks lateral (1) and (2) are properly braced with the braces obliques (5) (in this example in number of two and joined articulated in the form of a blade) to achieve stability due, and the board (6) lying between the side frames (1) and (2) resting on the crossbars (4) selected to the desired height There is also a horizontal brace (7) in the upper part, which acts as a railing and is always located at certain distance from the position occupied by the horizontal board (6).

En este ejemplo de realización, los bastidores laterales (1) y (2) son respectivos tramos de una escalera extensible, pues como se observa en la figura 1 el bastidor (1) cuenta superiormente con las bridas (8) ó abrazaderas de los largueros (3) del otro bastidor (2) deslizante, y este último dispone de los dos ganchos (9) de conexión en el travesaño seleccionado del bastidor lateral (1).In this exemplary embodiment, the racks lateral (1) and (2) are respective sections of a ladder extensible, as shown in figure 1 the frame (1) superiorly it has the flanges (8) or clamps of the stringers (3) of the other sliding frame (2), and the latter it has the two hooks (9) of connection in the crossbar selected from the side frame (1).

Para aumentar la estabilidad tanto del andamio como de la escalera, el bastidor lateral (1) dispone inferiormente de una barra transversal (10) cuyos extremos están en voladizo y provistos de sendos tacos de apoyo en el suelo.To increase the stability of both scaffolding as with the ladder, the side frame (1) has lower of a crossbar (10) whose ends are cantilevered and provided with two support tacos on the floor.

Con esta estructura el andamio puede convertirse en escalera y viceversa.With this structure the scaffolding can become on stairs and vice versa.

Una de las características básicas de la invención la determinan los medios de anclaje rápido y seguro para el montaje de los tirantes (5) en aspa y del tirante superior (7) ó barandilla, o bien, para el desmontaje del andamio.One of the basic characteristics of the invention is determined by fast and safe anchoring means for the mounting of the braces (5) on the blade and the upper brace (7) or railing, or, for the disassembly of the scaffolding.

En las figuras 2 y 3 pueden verse en detalle la estructura de estos medios de anclaje, definidos por un tetón ortogonal en ambos extremos aplanados de los tirantes (5), ó (7), el cual se introduce en el correspondiente orificio (11) seleccionado de los largueros (3), materializados estos orificios (11) en este caso por las embocaduras de los propios travesaños (4) que emergen al otro lado de los largueros (3).In figures 2 and 3 you can see in detail the structure of these anchoring means, defined by a stud orthogonal at both flattened ends of the braces (5), or (7), which is introduced in the corresponding hole (11) selected from the stringers (3), these holes materialized (11) in this case by the mouths of the crossbars themselves (4) that emerge on the other side of the stringers (3).

Además de este tetón que se observa con línea de trazos en la figura 3, existe un soporte acodado (12) (ver figura 3) que es giratorio alrededor de un tornillo-eje (13) coaxial con dicho tetón pero que gira por el exterior del tirante. En esta figura 3 el soporte acodado (12) ocupa por gravedad la posición de bloqueo del tirante (5) ó (7) porque no se permite el desplazamiento paralelo del tirante para provocar la salida del tetón, pues dicho soporte acodado (12) posee un tramo (14) transversal y otro final (15) que se vuelve paralelamente para abrazar parcialmente el larguero (3) evitando la salida accidental del tirante (ver también la figura 1).In addition to this busty that is observed with line of  strokes in figure 3, there is an angled support (12) (see figure 3) which is rotating around a screw-shaft (13) coaxial with said stud but that rotates outside the tight. In this figure 3 the layered support (12) occupies severity the locking position of the tie rod (5) or (7) because it is not allows parallel displacement of the tie rod to cause exit of the pin, since said angled support (12) has a section (14) transverse and another end (15) that turns in parallel to partially embrace the crossbar (3) avoiding accidental exit of the strap (see also figure 1).

Para desmontar el andamio, lo mismo que para montarlo, hay que elevar angularmente el soporte (12) para que la patilla extrema o tramo final (15) del doble acodamiento que experimenta el soporte (12), no se solape con el larguero (3) y entonces sí puede desplazarse paralelamente el tirante (5) ó (7).To disassemble the scaffolding, the same as for mount it, the support (12) must be raised angularly so that the extreme pin or final section (15) of the double bend that experience the support (12), do not overlap with the crossbar (3) and then the strap (5) or (7).

Otra característica de la invención podemos verla en la figura 4 y consiste en la forma de asegurar la estabilidad del tablero horizontal (6) que apoya sobre los dos travesaños (4) homólogos seleccionados de los dos bastidores laterales (1) y (2). Se lleva a cabo mediante las pletinas en "L" (16) invertida, solidarias a los costados del tablero (6), cuyas ramas libres descienden por fuera del travesaño (4) correspondiente evitando el deslizamiento. Como elemento de seguridad que complementa esta retención se dispone un gatillo de bloqueo (17) definido por una palanca que oscila en un punto medio (18) de la pletina en "L" (16) y que es portadora de un diente (19) inferior que se sitúa por gravedad debajo del travesaño (4), con lo que éste queda parcialmente abrazado y el tablero (6) totalmente inmovilizado. Existe un tope 20 en la pletina en "L" (16), de forma que el saliente (21) del gatillo (17) llegue a hacer tope con él cuando se desea desmontar el andamio, o para cambiar de posición en altura al tablero horizontal (6). Este pequeño giro es el suficiente para liberar el diente (19) respecto del travesaño (4).Another feature of the invention can we see it in figure 4 and it is the way to ensure the stability of the horizontal board (6) that rests on the two crossbars (4) selected counterparts from the two racks lateral (1) and (2). It is carried out by the plates in "L" (16) inverted, in solidarity with the sides of the board (6), whose free branches descend outside the crossbar (4) corresponding avoiding slippage. As an element of security that complements this retention is provided a trigger lock (17) defined by a lever that oscillates at a midpoint (18) of the "L" plate (16) and which is a carrier of a tooth (19) lower which is placed by gravity below the crossbar (4), so that it is partially embraced and the board (6) totally immobilized There is a top 20 on the plate in "L" (16), so that the projection (21) of the trigger (17) get to stop with him when you want to disassemble the scaffolding, or to change position in height to the horizontal board (6). This small turn is enough to release the tooth (19) with respect of the crossbar (4).
