Description
Puntal para obras.Strut for works.
La presente invención se refiere a un puntal para obras que presenta sensibles características de novedad y de actividad inventiva con respecto a los actualmente conocidos.The present invention relates to a strut for works that have sensitive characteristics of novelty and inventive activity with respect to those currently known.
El puntal para obras objeto de la presente
invención pertenece al tipo de los puntales fácilmente desmontables
que se utilizan preferentemente en obras de hormigón armado para el
soporte de elementos de la estructura de encofrado que deben
permitir su desmontaje parcial, de modo que después de un corto
periodo de fraguado de la estructura de hormigón se puede proceder
al desmontaje de una buena parte de los elementos de soporte del
encofrado para utilizarlos en otros lugares, habitualmente de la
misma
obra.The strut for works object of the present invention belongs to the type of easily removable struts that are preferably used in reinforced concrete works for the support of elements of the formwork structure that must allow their partial disassembly, so that after a short setting period of the concrete structure can proceed to disassemble a good part of the formwork support elements for use in other places, usually the same
work.
Para permitir una maniobra rápida de desmontaje de puntales el propio inventor de la invención actual ha desarrollado con anterioridad otros dispositivos destinados a la misma finalidad, tal como, por ejemplo, la Patente de Invención española con número de solicitud 200401355.To allow a rapid disassembly maneuver of props the inventor of the present invention himself has previously developed other devices intended for same purpose, such as, for example, the Invention Patent Spanish with application number 200401355.
La presente invención está destinada a permitir un rápido desacoplamiento del puntal aportando notables características de seguridad funcional. Ello se relaciona de modo inmediato con la invención anterior que se ha citado, en la que una pieza intermedia de tipo rotativo es portadora de un casquillo almenado con ranuras de estructura escalonada, dando lugar a dos zonas de acoplamiento de una segunda pieza montada por encima de la primera y que transmite la carga del puntal, de manera que en la posición de trabajo se debe encontrar apoyada en la parte alta de los escalones y en el momento del desmontaje se debe encontrar, después del giro de la pieza almenada, apoyada en el fondo de las aberturas de dicho almenado.The present invention is intended to allow a quick decoupling of the strut providing remarkable functional safety features. It is related in a way immediately with the above invention that has been cited, in which a intermediate piece of rotary type is carrying a bushing crenellated with grooves of stepped structure, giving rise to two coupling areas of a second piece mounted above the first and that transmits the strut load, so that in the work position should be found supported on the top of the steps and at the time of disassembly must be found, after turning the crenellated piece, resting on the bottom of the openings of said crenellated.
El puntal objeto de la presente invención pertenece al tipo anteriormente indicado, pero presenta características de mayor seguridad al impedir errores en la colocación de las piezas, ya que de modo automático éstas quedan dispuestas de la forma prevista para su funcionamiento sin posibilidad de error por parte del operario que efectúa la colocación del puntal, puesto que éste tiene medios propios que, de manera automática, colocan las dos piezas mencionadas, es decir, la portadora del almenado y la pieza superior desplazable verticalmente, en las posiciones idóneas de funcionamiento.The strut object of the present invention belongs to the type indicated above, but presents more secure features by preventing errors in the placement of the pieces, since they are automatically left arranged as intended for operation without possibility of error by the operator who performs the placement of the strut, since it has its own means that, of automatically, place the two pieces mentioned, that is, the crenellated carrier and movable top piece vertically, in the ideal operating positions.
De modo concreto, la presente invención prevé
que la parte almenada quede incorporada al casquillo fileteado
interiormente o "tuerca" de ajuste de altura del puntal,
mientras que la pieza superior giratoria es portadora de los topes
destinados a coincidir con el escalonado de las ranuras de la parte
almenada y también de las alas de accionamiento en giro y de topes
internos que evitan la salida de dicha pieza hacia arriba. El
dispositivo comprende un resorte helicoidal que trabaja
simultáneamente a torsión y a compresión y que impulsa a la pieza
superior desplazable en giro para su colocación en la posición
oportuna a tope sobre los escalones superiores del
almenado.Specifically, the present invention provides that the crenellated part is incorporated into the internally threaded bushing or "nut" of height adjustment of the strut, while the rotating upper part bears the stops intended to coincide with the stepping of the grooves of the crenellated part and also of the rotating drive wings and of internal stops that prevent the exit of said part upwards. The device comprises a helical spring that works simultaneously with torsion and compression and that drives the upper part movable in rotation for its placement in the opportune butt position on the upper steps of the
crenellated.
Para su comprensión se adjuntan a título de ejemplo explicativo, pero no limitativo, unos dibujos representativos de una realización preferente de la presente invención.For your understanding they are attached as explanatory example, but not limitative, some drawings representative of a preferred embodiment of the present invention.
La figura 1 muestra una vista en perspectiva de un puntal completo realizado de acuerdo con la presente invención.Figure 1 shows a perspective view of a complete strut made in accordance with this invention.
Las figuras 2 y 3 muestran sendas vistas en perspectiva del dispositivo que permite el desmontaje rápido del puntal, respectivamente en posición de trabajo y de desmontaje.Figures 2 and 3 show paths seen in device perspective that allows rapid disassembly of the strut, respectively in working position and disassembly.
Las figuras 5 y 6 muestran sendas vistas en perspectiva del dispositivo de desbloqueo rápido que corresponden respectivamente a las posiciones representadas en las figuras 2 y 3.Figures 5 and 6 show paths seen in quick release device perspective corresponding respectively to the positions represented in figures 2 and 3.
Tal como se observa en la figura 1, el puntal comprende un elemento inferior (1) de apoyo en el suelo y un elemento superior (2) sobre el que se apoya parte de la estructura de soporte del encofrado. Dicho tramo (2) del puntal presenta orificios (3) para ajustar su altura mediante un pasador en forma de argolla (4). Un dispositivo de desacoplamiento rápido (5) queda incorporado en la parte superior del elemento (1) del puntal y comprende un casquillo (6) fileteado interiormente o "tuerca", dotado de asas de manipulación (7) y (8) y de un anillo superior integral (9) portador de un almenado formado como mínimo por dos ranuras escalonadas, diametralmente opuestas, en las que se aloja la zona de tope de la pieza superior (10) que transmite la carga del puntal y que es giratoria en situación de trabajo por la acción de un resorte interno (11) que trabaja a compresión y a torsión, figura 4, y que en la posición de desbloqueo se desplaza verticalmente por la acción de la propia carga que se trasmite por el elemento superior del puntal (2).As shown in figure 1, the strut it comprises a lower support element (1) on the ground and a upper element (2) on which part of the structure rests formwork support. Said section (2) of the strut presents holes (3) to adjust its height using a shaped pin ring (4). A quick decoupling device (5) is left incorporated in the upper part of the element (1) of the strut and comprises an internally threaded bushing (6) or "nut", equipped with handling handles (7) and (8) and an upper ring integral (9) carrier of a crenellated at least two staggered, diametrically opposed grooves, in which it is housed the stop zone of the upper part (10) that transmits the load of the strut and that is rotating in work situation by action of an internal spring (11) that works with compression and torsion, Figure 4, and in the unlocked position it moves vertically by the action of the load itself that is transmitted by the upper element of the strut (2).
La pieza superior (10) es portadora de las alas (12) y (13) que permiten su fácil manipulación en giro y que presenta además en su borde inferior los topes salientes (14), de los que es visible solamente uno de ellos en la figura 4, que por una parte están destinados a apoyarse en el fondo (15) de las aberturas escalonadas de la parte superior (9) de la tuerca (6) en posición de desmontaje y que en posición de trabajo se apoyan sobre los escalones superiores (16) de la propia pieza.The upper part (10) is a carrier of the wings (12) and (13) that allow easy handling in rotation and that it also has on its lower edge the protruding stops (14), of which is visible only one of them in figure 4, which by a part are intended to rest on the bottom (15) of the stepped openings of the upper part (9) of the nut (6) in disassembly position and that in working position rest on the upper steps (16) of the piece itself.
Tal como se ha indicado, la posición de trabajo, es decir aquella en la que los topes (14) se apoyan en los escalones (16), se consigue por la acción de un resorte interno (11) que trabaja a compresión y a torsión presentando terminales (17) y (18) destinados a acoplarse respectivamente en una ranura interior de la tuerca (6) y en una ranura (19) de la pieza (10).As indicated, the work position, that is, the one in which the stops (14) rely on the steps (16), is achieved by the action of an internal spring (11) that works with compression and torsion presenting terminals (17) and (18) intended to engage respectively in a slot inside the nut (6) and in a groove (19) of the piece (10)
Se observa, por lo tanto, que el posicionado de la pieza (10) con respecto a la tuerca (6) tiene lugar de forma automática por la acción del resorte (11) correspondiendo a la posición levantada de dicha pieza en la que los topes (14) quedan dispuestos sobre los escalones superiores (16). De esta manera no hay posibilidad de error en la colocación del puntal. El desacoplamiento rápido se efectúa por la rotación de la pieza (10) actuando sobre las aletas (12) y (13), eventualmente mediante percusión, con lo que después del giro parcial de dicha pieza (10), al encararse los topes (14) con las escotaduras que presentan el fondo (15), la carga que gravita sobre la parte superior del puntal provoca el descenso de éste venciendo la acción del resorte y quedando en posición de desbloqueo.It is observed, therefore, that the positioning of the piece (10) with respect to the nut (6) takes place automatic by the action of the spring (11) corresponding to the raised position of said piece in which the stops (14) remain arranged on the upper steps (16). This way no there is a possibility of error in the placement of the strut. He Quick decoupling is done by rotating the part (10) acting on the fins (12) and (13), possibly by percussion, so that after the partial rotation of said piece (10), when facing the stops (14) with the recesses that present the bottom (15), the load that gravitates on the upper part of the strut causes the descent of this one overcoming the action of the spring and remaining in unlocked position.
Para evitar el desprendimiento hacia arriba de la pieza (10) por la acción del resorte (11) los topes (14) presentan estructura ligeramente saliente hacia el exterior, es decir, en sentido radial, con lo que hacen tope en su posición superior con un aro (20) incorporado en el anillo superior (9) de la pieza (6).To prevent upward detachment of the piece (10) by the action of the spring (11) the stops (14) they have a slightly protruding outward structure say, radially, with what they do butt in position upper with a ring (20) incorporated in the upper ring (9) of the piece (6).
Tal como se comprenderá, si bien se ha representado y descrito la invención en base a un ejemplo concreto, éste no tiene carácter limitativo y se podrían introducir numerosas modificaciones en el mismo siempre que estén comprendidas dentro del ámbito de las siguientes reivindicaciones.As will be understood, although it has been represented and described the invention based on a specific example, this is not limiting and many could be introduced modifications to it provided they are included within within the scope of the following claims.
