DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El puntal con medios de arriostramiento objeto de esta invención propone una solución alternativa para establecer la unión sencilla y segura entre puntales y medios de arriostramiento en orden a conformar unas torres de apeo rectangulares.The strut with bracing means object of this invention proposes an alternative solution to establish the simple and secure connection between struts and bracing means in order to form rectangular attachment towers.
El puntal está compuesto fundamentalmente por un tubo exterior y un tubo interior desplazable en sentido vertical respecto al primero por acción de una tuerca, y destaca principalmente porque en la cara externa del tubo exterior se encuentran unos nervios trapeciales axiales sobre los que abrazan unas garras de arriostramiento previstas en los extremos de unas estructuras tubulares que vinculan los puntales. La conjunción de varias estructuras tubulares que unen varios puntales conforman un marco de arriostramiento cerrado, preferentemente rectangular y definido entre cuatro puntales con los que configuran una torre de apeo.The strut is mainly composed of an outer tube and an inner tube that can be moved vertically with respect to the first by a nut, and it stands out mainly because axial trapecial nerves are found on the outer face of the outer tube on which claws are clamped. bracing provided at the ends of tubular structures that link the struts. The conjunction of several tubular structures that join several struts form a closed bracing frame, preferably rectangular and defined between four struts with which they form an attachment tower.
La garra de arriostramiento está compuesta por una garra fija, una garra móvil y una cuña. La garra fija está soldada a la estructura tubular y se adapta a la forma del tubo exterior del puntal, de modo que uno de los nervios trapeciales del tubo exterior queda alojado en un entrante definido en la garra fija, cuyo entrante muestra una configuración igualmente trapecial .The bracing claw is composed of a fixed claw, a movable claw and a wedge. The fixed claw is welded to the structure tubular and adapts to the shape of the outer tube of the strut, so that one of the trapecial nerves of the outer tube is housed in a defined recess in the fixed claw, whose recess shows an equally trapecial configuration.
La garra móvil puede girar respecto a la garra fija abrazando ambas al tubo exterior, estableciéndose la posición de bloqueo entre ambas mediante una cuña. La garra móvil dispone de una protuberancia de contacto que constituye el primer sector que incide con el tubo exterior durante la aproximación de la garra, de modo que la garra móvil bascula respecto a la garra fija hasta abrazar ambas al tubo exterior.The movable claw can rotate with respect to the fixed claw hugging both to the outer tube, establishing the blocking position between both by means of a wedge. The mobile claw has a contact protrusion that constitutes the first sector that impacts the outer tube during the approach of the claw, so that the mobile claw tilts with respect to the fixed claw until both of them embrace the outer tube.
Se han previsto dos garras móviles, simétricas, una garra móvil derecha y otra garra móvil izquierda.Two mobile clamps are provided, symmetrical, a right mobile claw and another left mobile claw.
La cuña es imperdible y juega en unas ranuras de la garra móvil, de manera que dicha cuña que presenta en su extremo inferior unos tetones puede en la operación de desbloqueo salir de la ranura inferior, dada la especial configuración de ésta, pero quedará retenida por la ranura superior más estrecha que los tetones, de manera que la cuña en ningún caso podrá separarse o independizarse de la garra móvil.The wedge is unmissable and plays in slots of the movable claw, so that said wedge that has at its lower end some lugs can in the unlocking operation leave the lower groove, given its special configuration, but will be retained by the upper groove narrower than the lugs, so that the wedge can in no case be separated or independent of the mobile claw.
De otro lado, la garra fija cuenta en su borde exterior curvo acodado de un rebaje en el que queda alojada la cuña en posición de bloqueo.On the other hand, the fixed claw has a curved outer edge of a recess in which the wedge is housed in the locked position.
Este montaje entre estructuras tubulares con garras extremas y los dos puntales se repite para otros puntales configurando finalmente un marco de arriostramiento cerrado que conforma junto a los puntales unas torres de apeo rectangulares.This assembly between tubular structures with extreme claws and the two struts is repeated for other struts finally configuring a closed bracing frame that forms next to the struts Rectangular attachment towers.
Por otra parte es de destacar que el tubo interior presenta una rosca trapezoidal de cuatro entradas para conseguir una regulación rápida, y que el tubo exterior dispone de unos resaltes internos que minimizan la holgura entre el tubo interior y el tubo exterior limitando la fricción a unos puntos de contacto, que pueden ser cuatro por ejemplo, facilitando así la regulación.On the other hand, it is noteworthy that the inner tube has a four-way trapezoidal thread to achieve rapid regulation, and that the outer tube has internal projections that minimize the clearance between the inner tube and the outer tube limiting friction to about contact points, which can be four for example, thus facilitating regulation.
La tuerca que regula la altura del tubo interior respecto al tubo exterior normalmente dispondrá de unas orejas que facilitan su giro, bien sea con ayuda de un martillo o haciendo palanca a través de una barra por ejemplo, estando previsto que interiormente en correspondencia con las orejas disponga de unos rebajes que interrumpen la rosca para facilitar la evacuación de la posible suciedad acumulada en la rosca garantizando su limpieza.The nut that regulates the height of the inner tube with respect to the outer tube will normally have ears that facilitate its rotation, either with the help of a hammer or by prying through a bar for example, being provided that internally in correspondence with the ears have recesses that interrupt the thread to facilitate the evacuation of the possible dirt accumulated in the thread guaranteeing its cleaning.
El puntal incorpora asimismo una placa intermedia unida mediante un remache al extremo del tubo exterior que constituye el apoyo sobre el que gira y descansa la tuerca y apoya el tubo interior, así como se constituye en el soporte al que se vincula un enganche que asimismo acopla sobre la base de la tuerca estableciendo la unión entre el tubo interior y el tubo exterior una vez ajustada la regulación.The strut also incorporates an intermediate plate joined by means of a rivet to the end of the outer tube that constitutes the support on which the nut rotates and rests and supports the inner tube, as well as constitutes the support to which a coupling is attached which also attaches on the base of the nut establishing the union between the inner tube and the outer tube once the regulation is adjusted.

La cuña (16) , imperdible, es decir, que permanece siempre unida a la garra móvil (14) , juega en unas ranuras (18) y (19) de dicha garra móvil (14) , quedando introducida en ambas ranuras en posición de bloqueo, en tanto que en el desbloqueo, el extremo inferior de la cuña, que presenta unos tetones, puede salir de la ranuraDuring the approach of the bracing claws (9) to the outer tube (1), the mobile claw (14) strikes the outer tube (1) by means of a contact protrusion (17) which determines the tilting of the mobile claw ( 14) towards the outer tube (1), which will thus be embraced by the fixed claw (11) and the movable claw (14) and the hug locked by the wedge (16). The wedge (16), unmissable, that is, that always remains attached to the mobile claw (14), plays in some slots (18) and (19) of said mobile claw (14), being inserted into both slots in the position of blocking, while in the unlocking, the lower end of the wedge, which has a few lugs, can leave the slot
(19) , dada la especial configuración de ésta, pero no así de la ranura (18) , más estrecha que los tetones, de manera que la cuña (16) permanece siempre unida a la garra móvil (14) . Asimismo, la garra fija presenta en su periferia, concretamente en la zona acodada, un rebaje (20) en el que queda alojada la cuña (16) para bloquear las garras.(19), given its special configuration, but not the groove (18), narrower than the lugs, so that the wedge (16) always remains attached to the movable claw (14). Also, the fixed claw has on its periphery, specifically in the angled area, a recess (20) in which the wedge (16) is housed to block the claws.
Por otra parte cabe destacar que el tubo interior (2) del puntal dispone de una rosca trapezoidal (21) de cuatro entradas que permite un giro rápido de la tuercaOn the other hand, it should be noted that the inner tube (2) of the strut has a four-way trapezoidal thread (21) that allows a quick turn of the nut
(3) y por tanto una regulación rápida en altura del puntal, así como el tubo exterior (1) dispone interiormente de unos resaltes (22) que minimizan la holgura entre tubo interior (2) y tubo exterior (1) limitando la posible fricción entre éstos al contacto entre el tubo interior (2) y los resaltes (22) de modo que no se vea dificultada la regulación. (3) and therefore a quick adjustment in height of the strut, as well as the outer tube (1) internally has projections (22) that minimize the clearance between inner tube (2) and outer tube (1) limiting the possible friction between them to the contact between the inner tube (2) and the projections (22) so that regulation is not hindered.
