Estructura soporte para tableros de encofrado.Support structure for boards formwork

Objeto de la invenciónObject of the invention

La presente invención se refiere a una estructura de soporte para tableros de los utilizados en la obtención de encofrados planos, entendiéndose por tablero cualquier placa capaz de configurar, en conjunción con otras similares, la superficie plana prevista para el encofrado.The present invention relates to a support structure for boards used in the Obtaining flat formwork, meaning any board board capable of configuring, in conjunction with similar ones, the flat surface intended for formwork.

El objeto de la invención es conseguir una estructura que, además de ser recuperable y fácilmente desmontable, ofrezca un alto grado de rigidez estructural, soportando sin deformación las cargas a que se va a ver sometida.The object of the invention is to achieve a structure that, in addition to being recoverable and easily removable, offer a high degree of structural rigidity, supporting without deformation of the loads to be subjected.

Antecedentes de la invenciónBackground of the invention

A la hora de establecer una superficie plana de encofrado, una soluciones conocida consiste en la disposición de una serie de largueros paralelos, distanciados en correspondencia con la anchura de los tableros que han de constituir mayoritariamente la superficie de encofrado, tableros que quedan enrasados con la cara superior de los citados largueros, apoyando tales tableros sobre soportes laterales fijables con carácter amovible a los largueros y que definen con estos últimos escalonamientos latero-superiores para apoyo de los tableros.When establishing a flat surface of formwork, a known solution consists in the provision of a series of parallel stringers, spaced apart in correspondence with the width of the boards to be constituted mostly the formwork surface, remaining boards flush with the upper face of the mentioned stringers, supporting such boards on lateral supports that can be fixed with character removable to the stringers and defining with the latter latero-superior staging for support of boards

Cada pareja de soportes destinados a acoplarse lateralmente a un mismo larguero están unidos entre sí mediante tres puentecillos inferiores, uno intermedio y dos extremos, de los que el intermedio esta provisto a su vez de un pasador que constituye el medio de fijación de la pareja de soportes al larguero, con la colaboración de un casquillo solidarizado transversalmente a la cara inferior del larguero.Each pair of brackets intended to be coupled laterally to the same crossbar they are joined together by three lower bridges, one intermediate and two ends, of the that the intermediate is provided with a pin that it constitutes the means of fixing the pair of supports to the stringer, with the collaboration of a solidarity cap transversely to the underside of the crossbar.

Una solución de este tipo puede observarse, por ejemplo, en el modelo de utilidad U9202210, del que es titular el propio solicitante.Such a solution can be observed, by example, in utility model U9202210, of which the own applicant.

Como se deduce de lo anteriormente expuesto cada tablero o grupo de tableros apoya sobre dos soportes que a su vez quedan suspendidos de los largueros exclusivamente en dos puntos, concretamente en el punto medio de cada uno de ellos, lo que hace que dichos soportes, generalmente metálicos y consecuentemente provistos de cierta elasticidad, flexionen por efecto de la carga, es decir se deformen, permitiendo ligeras basculaciones en los tableros sobre los que trabajan y pisan los operarios, con el consecuente riesgo de caída para los mismos, deformaciones que pueden trasladarse en su caso a la cara inferior del forjado, obtenido con el encofrado en cuestión, y limitando la capacidad portante máxima de los soportes al pasador único que los relaciona con los largueros.As deduced from the above, each board or group of boards supports on two supports that in turn they are suspended from the stringers exclusively at two points, specifically at the midpoint of each one of them, what it does that said supports, generally metallic and consequently provided with a certain elasticity, flex due to the effect of the load, that is to say they are deformed, allowing slight tilts in the boards on which the workers work and step on, with the consequent risk of falling for them, deformations that they can be moved where appropriate to the underside of the floor, obtained with the formwork in question, and limiting the capacity maximum bearing support to the single pin that relates them With the stringers.

Descripción de la invenciónDescription of the invention

La estructura que la invención propone ha sido concebida en orden a resolver de forma plenamente satisfactoria la problemática anteriormente expuesta, asegurando una óptima rigidización de los soportes a los largueros, con un acusado incremento en su capacidad portante y una deformabilidad prácticamente nula, y todo ellos sin menoscabo en la facilidad de montaje y desmontaje del encofrado.The structure proposed by the invention has been conceived in order to resolve in a fully satisfactory manner the problem discussed above, ensuring optimal stiffening of the supports to the stringers, with a defendant increase in bearing capacity and deformability practically null, and all of them without prejudice to the ease of formwork assembly and disassembly.

Para ello y de forma más concreta y a partir de la estructuración básica y convencional anteriormente citada, la invención se centra en el hecho de que los largueros incorporan, a ambos lados de cada casquillo transversal y fijo para el pasador de una pareja de soportes, en correspondencia posicional con los puentecillos extremos de este último, sendos elementos de enganche para los puentecillos del soporte, destinados a acoplarse a estos últimos por desplazamiento longitudinal del soporte con respecto al larguero, es decir mediante un acoplamiento por deslizamiento longitudinal que establece además una situación limite en la que el pasador queda ineludiblemente enfrentado al casquillo transversal del larguero, por lo que también se facilita el montaje de dicho pasador.To do this and more specifically and from the basic and conventional structuring mentioned above, the invention focuses on the fact that the stringers incorporate, to both sides of each transverse and fixed bushing for the pin a pair of supports, in positional correspondence with the extreme bridges of the latter, two hook elements for the support bridges, intended to be coupled to these last by longitudinal displacement of the support with respect to the stringer, that is by sliding coupling longitudinal that also establishes a limit situation in which the pin is inevitably facing the transverse bushing of the stringer, so it is also easy to assemble it Barrette.

Los elementos de enganche pueden materializarse en un perfil en "L", capaz de abrazar ajustadamente al citado puentecillo del soporte, en un perfil en "L" reforzado mediante una costilla exterior, en cualquiera de las dos soluciones anteriores con la extremidad libre de su rama inferior arqueada para facilitar el acoplamiento y el acuñamiento, mediante un perfil en "Z" mediante un perfil angular o en "Z" provisto de un tetón enchufable simultáneamente en un orificio del puentecillo, etc.The hooking elements can materialize in an "L" profile, capable of hugging the aforementioned support bridge, in a reinforced "L" profile by an outer rib, in any of the two solutions anterior with the free limb of its arched lower limb to facilitate coupling and coining, through a profile in "Z" by means of an angular profile or in "Z" provided with a plug-in brass simultaneously in a hole in the bridge, etc.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como en la estructura soporte para tableros de encofrado que la invención propone, como en cualquier estructura convencional de este tipo, participa una pluralidad de largueros (1), materializados en perfiles tubulares de sección rectangular, que se disponen equidistanciados apoyando sobre travesaños o directamente sobre puntales de sustentación, quedando dichos largueros (1) distanciados en correspondencia con el tamaño de los tableros (2), y recibiendo dichos largueros (1) a lo largo de su trayectoria, a una pluralidad de soportes (3), materializado cada uno de ellos en dos perfiles paralelos y distanciados en una magnitud a corte con la anchura de los largueros (1), perfiles relacionados entre si mediante dos puentecillos extremos (4) y un puente intermedio (5), de configuración en "U", con orificios en sus ramas laterales en los que juega un pasador (6) que configura una especie de "J" enchufable en un casquillo (7) soldado transversalmente a la cara inferior de los largueros (1), en puntos adecuadamente distanciados del mismo de acuerdo con la longitud de los soportes (3), de manera que en situación de montaje para los soportes (3) estos definen con los largueros (1) escalonamientos latero-superiores (8) para acoplamiento de los extremos de los tableros (2), donde estos últimos se apoyan quedando su cara superior enrasada con la cara superior de los largueros (1).In view of the figures outlined you can be observed as in the support structure for formwork boards that the invention proposes, as in any conventional structure of this type, a plurality of stringers (1) participates, materialized in tubular profiles of rectangular section, which have equidistance supported on crossbars or directly on support struts, said stringers remaining (1) distanced in correspondence with the size of the boards (2), and  receiving said stringers (1) along its trajectory, at a  plurality of supports (3), each materialized in two parallel and spaced profiles in a magnitude cut with the width of the stringers (1), profiles related to each other by two extreme bridges (4) and an intermediate bridge (5), "U" configuration, with holes in its lateral branches in which a pin (6) plays a kind of "J" pluggable into a socket (7) welded transversely to the underside of the stringers (1), in points properly distanced from it according to the length of the supports (3), so that in mounting situation for the supports (3) these define with the stringers (1) steps Lateral-upper (8) for coupling the ends of the boards (2), where the latter are supported leaving its upper face flush with the upper face of the stringers (1).

Esto supone, tal como muestra la figura 2, que tras el montaje del encofrado y cuando este recibe cargas superiores, al estar los soportes (3) fijados a los largueros (1) exclusivamente por su punto medio, los esfuerzos de sus extremos representados mediante flechas en la figura (2) hace que dichos soportes (3) flexen elásticamente, es decir que se produzca un descenso en sus zonas extremas con un paralelo arqueamiento de los mismos, lo que hace que el apoyo para los tableros (2) sea inestable.This assumes, as Figure 2 shows, that after mounting the formwork and when it receives loads upper, being the supports (3) fixed to the stringers (1) exclusively for its midpoint, the efforts of its extremes represented by arrows in figure (2) makes said supports (3) flex flexibly, that is to say that a descent in its extreme zones with a parallel arching of the themselves, which makes the support for the boards (2) unstable.

Pues bien, de acuerdo ya con la invención este problema se resuelve tal como muestra la figura (3), mediante la fijación a la cara inferior de los largueros (1) y en correspondencia con cada uno de los puentecillos extremos (4), de un elemento de enganche (9), materializado por ejemplo en un perfil angular, quedando ambos perfiles angulares (9-9') orientados en el mismo sentido, es decir determinando aberturas laterales orientadas hacia el mismo lado, de amplitud acorde con la altura de los puentecillos (4), de manera que tras una pre-adaptación de los soportes (3) a los largueros (1), hasta que los puentecillos (4) hacen tope con la cara inferior de dichos largueros (1), el soporte (3) se desplazable en el sentido de flecha de la citada figura (3) hasta que los puentecillos (4) encajan en los citados alojamientos definidos por los angulares (9), quedando inmovilizados a través de este último con respecto a los largueros (1), situación límite en la que además el pasador (6) convencional queda enfrentado al casquillo (7) correspondiente del larguero (1), consiguiéndose de esta manera que el soporte (3) quede solidariamente fijado tanto por su zona media como por sus extremos.Well, according to the invention this problem is solved as shown in figure (3), by fixing to the underside of the stringers (1) and in correspondence with each of the extreme bridges (4), of a coupling element (9), materialized for example in a profile angular, leaving both angular profiles (9-9 ') oriented in the same direction, that is, determining openings sideways facing the same side, of amplitude consistent with the height of the bridges (4), so that after a pre-adaptation of the supports (3) to the stringers (1), until the jumpers (4) face the bottom face of said stringers (1), the support (3) can be moved in the direction  arrow of the aforementioned figure (3) until the bridges (4) fit the aforementioned housings defined by the angular ones (9), being immobilized through the latter with respect to the stringers (1), limit situation in which in addition the pin (6) conventional is facing the corresponding bushing (7) of the crossbar (1), thus achieving that the support (3) is fixedly fixed both by its middle zone and its extremes

A partir de esta solución básica y como también muestra la figura 3, es factible que el perfil angular (9) este rigidizado mediante una costilla exterior (10), que dicho perfil angular (9) presente su extremidad libre (11) ligeramente arqueada, para facilitar la penetración del puentecillo (4) en su interior, que el perfil angular (9) pueda ser sustituido por dos varillas angulares (12), que lo sea por un perfil en "Z" (13) que incrementa notablemente la zona de fijación por soldadura en la cara inferior del larguero (1), que dicho perfil en "Z" (13) tenga además un tetón intermedio (14) enchufable en un orificio (15) del puentecillo (4) definiendo un doble apoyo, que el tetón (14) se sitúe en un perfil angular (9) con el extremo arqueado (11) anteriormente citado, o que simplemente se trate de una pequeña pletina rectangular con el citado tetón (14) como muestra la última realización de la figura 3, siendo evidente que, como anteriormente se ha dicho, estas ocho realizaciones corresponden a otros tantos ejemplos o posibilidades de realización practica, dentro de la amplia gama de soluciones para el elemento de enganche (9), obvias para un experto en la materia.From this basic solution and as well as Figure 3 shows, it is feasible that the angular profile (9) is stiffened by an outer rib (10), which said profile angular (9) present its free tip (11) slightly arched, to facilitate the penetration of the bridge (4) inside, that the angular profile (9) can be replaced by two rods angular (12), that it be for a "Z" profile (13) that remarkably increases the fixing area by welding on the face  bottom of the crossbar (1), that said "Z" profile (13) has also an intermediate pin (14) pluggable into a hole (15) of the bridge (4) defining a double support, that the pin (14) is place in an angular profile (9) with the arched end (11) previously cited, or that it is simply a small rectangular plate with the aforementioned pin (14) as shown in the last embodiment of figure 3, it being evident that, as before It has been said, these eight realizations correspond to many others examples or possibilities of practical realization, within the wide range of solutions for the coupling element (9), obvious For an expert in the field.
