Dispositivo de acoplamiento entre pilares y cerchas, para estructuras modulares desmontables.Coupling device between pillars and trusses, for removable modular structures.

Object of the invention

La presente invención se refiere a un dispositivo especialmente concebido para el acoplamiento entre pilares y cerchas, en estructuras metálicas modulares desmontables, para las que se requiere de un montaje y desmontaje rápidos.The present invention relates to a device specially designed for coupling between pillars and trusses, in removable modular metal structures, for which rapid assembly and disassembly is required.

El objeto de la invención es optimizar dichas operaciones, y en especial poder llevarlas a cabo sobre el suelo, o a un nivel en altura adecuado para trabajar en óptimas condiciones tanto de comodidad como de seguridad.The object of the invention is to optimize said operations, and especially being able to carry them out on the ground, or at a height level suitable for working in optimal conditions both comfort and safety.

La invención resulta de especial aplicación en el ámbito de la industria destinada a la fabricación y montaje de stands para ferias y exposiciones y de otras construcciones que tengan que ser montadas/desmontadas de forma frecuente.The invention is of special application in the scope of the industry for the manufacture and assembly of stands for fairs and exhibitions and other constructions that have to be assembled / disassembled frequently.

Background of the invention

En el ámbito preferente de aplicación práctica citado, el de los módulos para exposiciones en recintos feriales y similares, cada módulo está constituido generalmente a base de cuatro pilares, dispuestos en los imaginarios vértices de un cuadrado o rectángulo, unidos entre sí mediante cerchas perimetrales que se fijan en su extremo superior, siendo estos módulos acoplables a otros idénticos determinando una estructura reticular susceptible de crecer según las coordenadas de un sistema cartesiano, complementándose la estructura con cerchas intermedias, en cada módulo, para definir una cubierta.In the preferred scope of practical application cited, the modules for exhibitions in fairgrounds and similar, each module is generally made up of four pillars, arranged in the imaginary vertices of a square or rectangle, joined together by trusses perimetral that are fixed at its upper end, these being modules that can be attached to identical ones determining a structure reticular susceptible to grow according to the coordinates of a system Cartesian, complementing the structure with intermediate trusses, in each module, to define a cover.

El acoplamiento de las cerchas a los pilares debe permitir unas manipulaciones de montaje y desmontaje rápidas y sencillas, pero a la vez las uniones deben ofrecer la debida solidez.The coupling of the trusses to the pillars it must allow quick assembly and disassembly manipulations and simple, but at the same time the unions must offer due solidity.

Estos objetivos se consiguen con la estructura modular de ensamblaje rápido que constituye el objeto del Modelo de Utilidad 9603374, del que es titular el propio solicitante, estructura en la que los pilares, de sección cuadrangular, incorporan en cada una de sus caras y en su extremidad superior una pareja de perfiles acanalados, de concavidades enfrentadas, determinantes cada pareja, con la cara correspondiente del pilar, de acanaladuras de embocadura estrangulada convergentes en sentido descendente, estando estas acanaladuras destinadas a recibir a sendas chapas de configuración trapecial isoscélica, que rematan los extremos de las cerchas, consiguiéndose de esta manera un acoplamiento machihembrado, con acuñamiento, que permite asegurar un fácil montaje y una adecuada resistencia estructural de la armadura en su conjunto.These objectives are achieved with the structure fast assembly modular that is the object of the Model Utility 9603374, which the applicant himself owns, structure in which the pillars, of quadrangular section, incorporate in each of their faces and in their upper limb a couple of ribbed profiles, of facing concavities, determinants each couple, with the corresponding face of the pillar, of strangled spout grooves converging in direction descending, these grooves being destined to receive paths of isoscelic trapezoid configuration, which finish off the ends of the trusses, thus achieving a tongue and groove coupling, with wedging, which ensures easy assembly and adequate structural strength of the armor as a whole.

Sin embargo esta solución presenta una problemática que se centra fundamentalmente en dos aspectos:However, this solution presents a problematic that focuses primarily on two aspects:

--: El montaje se realiza fijando inicialmente los pilares, para posteriormente fijar al extremo superior de dichos pilares las cerchas, lo que supone que el acoplamiento de las placas y de las cerchas se ha de realizar a considerable altura, concretamente a la de los pilares, lo que supone que dicho trabajo de montaje se produzca en condiciones incómodas y con un riesgo importante de accidentes por caída al vacío.He assembly is done by initially fixing the pillars, to subsequently fix to the upper end of said pillars the trusses, which means that the coupling of the plates and the trusses must be carried out at considerable height, specifically to the of the pillars, which means that said assembly work is produce in uncomfortable conditions and with a significant risk of accidents due to vacuum drop.

--: Dado que las acanaladuras definidas por las respectivas parejas de perfiles acanalados fijados a cada una de las caras del pilar están abiertas tanto superior como inferiormente, la situación límite inferior para las cerchas viene determinada por el definitivo acuñamiento de las placas trapeciales en el seno de dichas acanaladuras, efecto de acuñamiento que por diferentes causas, como por ejemplo por la carga de las cerchas intermedias, por la carga de objetos complementarios sobre la estructura del techo, o por otras razones, se incrementa con el tiempo, constituyendo un serio problema a la hora de desacoplar cada placa de su correspondiente acanaladura, sobre todo teniendo en cuenta que esta maniobra también hay que hacerla a un considerable nivel en altura con respecto al suelo.Dice that the grooves defined by the respective pairs of corrugated profiles fixed to each of the pillar faces are open both upper and lower, the limit situation bottom for trusses is determined by the definitive wedging of the trapezoid plates within these grooves, coining effect that for different reasons, such as for example by the loading of intermediate trusses, by the load of complementary objects on the roof structure, or by other reasons, it increases over time, constituting a serious problem when decoupling each plate from its corresponding grooving, especially considering that this maneuver it must also be done at a considerable level in height with With respect to the ground.

Description of the invention

El dispositivo de acoplamiento que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, en los dos aspectos comentados, de manera que por un lado permite realizar la mayor parte del trabajo a nivel del suelo, y no solo de módulos aislados sino de una buena parte o la totalidad de los módulos que participan en la estructura, y por otro asegura un fácil desmontaje de las cerchas en el momento en el que esta operación sea necesaria.The coupling device that the invention proposes to solve the problem fully satisfactorily previously stated, in the two aspects mentioned, so which on the one hand allows to carry out most of the work at the level of the ground, and not only of isolated modules but of a good part or all the modules that participate in the structure, and by another ensures easy disassembly of the trusses at the time the This operation is necessary.

Para ello, de forma mas concreta y de acuerdo con una de las características de la invención, cada pilar está fragmentado en dos porciones, una inferior y mayoritaria, y otra superior, de escasa altura, la imprescindible para la implantación de los perfiles constitutivos de las acanaladuras receptoras de las placas, prolongada inferiormente en un cuello o estrechamiento perimetral, de manera que esta porción superior es susceptible de acoplarse, por enchufamiento, en la extremidad superior de la porción inferior y mayoritaria.To do this, more specifically and in agreement With one of the characteristics of the invention, each pillar is fragmented into two parts, one inferior and majority, and another upper, low height, the essential for implementation of the constituent profiles of the receiving grooves of the plates, prolonged inferiorly in a neck or narrowing perimeter, so that this upper portion is susceptible to engage, by plugging, in the upper extremity of the lower and majority portion.

De esta manera todas las cerchas participantes en la estructura pueden ser montadas a nivel del suelo sobre los correspondientes cabezales o porciones superiores e independientes de los pilares, y tras dicho montaje la estructura en su conjunto es elevada, mediante mecanismos elevadores apropiados, procediendo a enchufar dichos cabezales en los respectivos cuellos de los también respectivos pilares, lo que no impide que el montaje pueda realizarse también en altura, cuando sea necesario.In this way all the participating trusses in the structure they can be mounted at ground level on the corresponding heads and upper and independent portions of the pillars, and after said assembly the structure as a whole is elevated, by appropriate lifting mechanisms, proceeding to plug said heads into the respective necks of the also respective pillars, which does not prevent the assembly from being able to also be carried out in height, when necessary.

De acuerdo con otra de las características de la invención, cada cabezal o porción superior de los pilares incorpora en cada una de sus caras un orificio sensiblemente centrado, destinado a recibir a un cerrojo instalado sobre cada uno de los extremos de las cerchas, de manera que el accionamiento de dichos cerrojos provoca el bloqueo entre cabezales y cerchas, impidiendo el desacoplamiento de estas últimas durante la maniobra de elevación de la estructura, con independencia de que ésta se lleve a cabo actuando sobre los cabezales o sobre cualquier punto intermedio o extremo de las cerchas. No obstante el citado cerrojo puede ser sustituido por un simple tornillo.According to another of the characteristics of the invention, each head or upper portion of the pillars incorporates in each of its faces a hole that is substantially centered, intended to receive a bolt installed on each of the ends of the trusses, so that the actuation of said bolts causes blockage between heads and trusses, preventing the decoupling of the latter during the maneuver of elevation of the structure, regardless of whether it takes out acting on the heads or on any point intermediate or extreme trusses. Notwithstanding the aforementioned bolt It can be replaced by a simple screw.

Finalmente y de acuerdo con otra de las características de la invención, se ha previsto que los perfiles acanalados que constituyen las acanaladuras convergentes de cada una de las caras de cada cabezal, estén cerrados por su extremidad inferior, constituyendo un tope limitador de penetración para las placas trapeciales de las cerchas, y consecuentemente impidiendo que pueda producirse un acuñamiento excesivo que dificulte el posterior desmontaje. Lógicamente el cierre de los perfiles acanalados se produce en el nivel en altura correspondiente al borde inferior de las placas trapeciales, en situación de perfecto ajuste entre dichas placas y los perfiles acanalados, inmediatamente antes de que empiece a producirse un forzamiento de tales perfiles por el citado acuñamiento.Finally and according to another of the characteristics of the invention, it is provided that the profiles flutes that constitute the convergent grooves of each of the faces of each head, are closed by its limb lower, constituting a penetration limit stop for trapeze plates of the trusses, and consequently preventing that excessive coining may occur that hinders the subsequent disassembly. Logically closing the profiles fluted occurs at the height level corresponding to the lower edge of the trapeze plates, in a perfect situation fit between said plates and ribbed profiles, immediately before a forcing begins to occur such profiles by said coining.

Preferred Embodiment of the Invention

A la vista de la figuras reseñadas puede observarse como, de acuerdo con el dispositivo de acoplamiento que se preconiza, cada pilar (1) de la estructura modular, con la clásica sección cuadrangular, presenta un tramo inferior que se corresponde con la propia referencia (1) y que es claramente mayoritario en altura, que recibe por su extremidad superior a un cuello (2) remetido perimetralmente, perteneciente a un cabezal (3), que constituye el tramo superior o de remate del pilar, cabezal que apoya sobre la embocadura (4) del tramo inferior (1) del pilar, y que es el que está provisto en cada una de sus caras de las respectivas parejas de perfiles acanalados (5), que debidamente solidarizados al cabezal, por ejemplo mediante soldadura, y con sus concavidades enfrentadas, definen una acanaladura intermedia (6), de embocadura acusadamente estrangulada y de amplitud progresivamente decreciente en sentido descendente, para recibir en su seno, por acoplamiento machihembrado, a las placas trapeciales (7) que rematan los extremos de las cerchas (8).In view of the figures outlined you can be observed as, according to the coupling device that it is recommended, each pillar (1) of the modular structure, with the Classic quadrangular section, it has a lower section that corresponds to the reference itself (1) and that is clearly majority in height, which receives from its upper extremity than a neck (2) tucked perimeter, belonging to a head (3), which constitutes the upper or top section of the pillar, head that it rests on the mouth (4) of the lower section (1) of the pillar, and which is the one that is provided in each of its faces of the respective pairs of ribbed profiles (5), which duly solidarity with the head, for example by welding, and with its facing concavities, define an intermediate groove (6), of sharply strangled mouthpiece and amplitude progressively decreasing downwards, to receive in its breast, by tongue and groove coupling, to the trapezoidal plates (7) that ends the ends of the trusses (8).

De acuerdo con otra de las características de la invención y como anteriormente se ha dicho, los perfiles (5) presentan su extremidad inferior (9) cerrada, de manera que estos cierres inferiores (9) constituyen topes limitadores de penetración para las placas trapeciales (7), impidiendo un acuñamiento excesivo de las cerchas con respecto a los cabezales.According to another of the characteristics of the invention and as previously stated, the profiles (5) they have their lower limb (9) closed, so that these lower closures (9) constitute penetration limiting stops for the trapecial plates (7), preventing excessive coining of the trusses with respect to the heads.

Tal como anteriormente se ha dicho, el hecho de que los cabezales (3) sean físicamente independientes del resto de los pilares respectivos (1), permite que las cerchas (8) se monten sobre los cabezales (3) a nivel del suelo, es decir en condiciones de óptima comodidad laboral y sin el menor riesgo de accidentes por caída, de manera que, como también se ha dicho con anterioridad, toda la estructura de cubierta puede montarse a nivel del suelo, con independencia de cual sea el número de módulos que participen en la misma, y posteriormente ser elevada, mediante carretillas elevadoras, una grúa, u otros medios apropiados, para ser definitivamente apoyada sobre la extremidad superior de los pilares, y estabilizada por inserción de los cuellos en U de este último en el interior hueco de los cabezales (3).As previously stated, the fact of that the heads (3) are physically independent of the rest of the respective pillars (1), allows the trusses (8) to be mounted on the heads (3) at ground level, that is to say in conditions Optimal work comfort and without the least risk of accidents due to fall, so that, as has been said before, The entire roof structure can be mounted at ground level, regardless of the number of modules that participate in it, and subsequently be lifted, by wheelbarrows elevators, a crane, or other appropriate means, to be definitely resting on the upper extremity of the pillars, and stabilized by insertion of the U-necks of this last in the hollow interior of the heads (3).

Para evitar que en esta maniobra de elevación de las estructura los cabezales (3) puedan desacoplarse de las cerchas (8), se ha previsto que dichos cabezales (3) incorporen sobre cada una de sus caras un orificio (10), que en situación de montaje de las cerchas (8) queda enfrentado a otro orificio (11) de la placa (7) correspondiente de la cercha, estando dicho orificio (10) destinado a recibir a un cerrojo (12), montado sobre el extremo de la propia cercha (8), cerrojo que es retráctil en contra de la tensión de un muelle (13) y que es accionable mediante una maneta (14). De esta manera cuando el cerrojo pasador (12) ha atravesado el orificio (11) de la placa (7) accede al seno del cabezal (3) a través del orificio (10), cabezal y cercha quedan inmovilizados, no solo en sentido transversal por efecto del acuñamiento de la placa (11) en la acanaladura (6), sino también en sentido vertical debido al cerrojo (12). No obstante se ha previsto la alternativa, también representada gráficamente en la figura 3, de sustituir el cerrojo (12) por un simple tornillo (15) que, pasando a través del correspondiente orificio (10), rosque sobre dicho orificio o sobre la propia estructura de la cercha.To prevent this lifting maneuver from the structure the heads (3) can be disengaged from the trusses (8), it is planned that said heads (3) incorporate on each one of its faces a hole (10), which in the situation of mounting the trusses (8) face another hole (11) of the plate (7) corresponding to the truss, said hole (10) being intended to receive a bolt (12), mounted on the end of the truss itself (8), a bolt that is retractable against the tension of a spring (13) and that is operable by means of a handle (14). In this way when the bolt (12) has passed through the hole (11) of the plate (7) accesses the head of the head (3) to through the hole (10), head and truss are immobilized, not only transversely due to the effect of plate wedging (11) in the groove (6), but also vertically due to the bolt (12). However, the alternative is planned, also plotted in figure 3, to replace the bolt (12) by a simple screw (15) that, passing through the corresponding hole (10), thread on said hole or envelope The structure of the truss itself.

Solo resta señalar por último que el cuello (2) prolongación inferior del cabezal (3), puede adoptar una sección cuadrangular dimensionalmente coincidente con la sección interior del pilar (1), para acoplarse ajustadamente a este último, o bien y con miras a facilitar su montaje, puede presentar una configuración ligeramente tronco-piramidal, convergente hacia su extremidad libre, que afecte a toda su extensión o a una parte próxima de dicha extremidad libre, para facilitar la penetración en el interior hueco del cabezal.It only remains to point out finally that the neck (2) lower extension of the head (3), can adopt a section quadrangular dimensionally coincident with the inner section of the pillar (1), to fit tightly to the latter, or With a view to facilitating its assembly, you can present a configuration slightly trunk-pyramidal, convergent towards its free limb, which affects its entire extension or a part near said free limb, to facilitate penetration into the hollow interior of the head.
