La presente invención se refiere a un puntal para obras que presenta nuevas y ventajosas características con respecto al estado de la técnica.The present invention relates to a strut for works that presents new and advantageous features with regarding the state of the art.
Los puntales para obras son de muy amplia utilización en la industria de la construcción para apoyar diferentes estructuras o elementos durante la realización de la obra.The props for works are very wide use in the construction industry to support different structures or elements during the realization of the work.
Básicamente los puntales de tipo universalmente utilizado comprenden dos tubos montados de forma telescópica que presentan respectivamente una base o pletina inferior y una pletina superior para apoyar el puntal respectivamente en la parte baja, como puede ser un forjado de piso ya realizado o el suelo, y en la parte alta que corresponderá al elemento a soportar. Los elementos tubulares se pueden ajustar en cuanto a longitud de forma telescópica, fijándose mediante pasadores desmontables en el punto deseado de ajuste, que después se puede complementar con un ajuste de afino de la altura mediante una tuerca que actúa haciendo variar la posición axial definitiva del tubo interior.Basically type struts universally used comprise two telescopic mounted tubes that they have respectively a base or lower plate and a plate upper to support the strut respectively in the lower part, such as a floor slab already made or the floor, and in the high part that will correspond to the element to support. The elements Tubular can be adjusted for shape length telescopic, fixed by detachable pins on the point desired adjustment, which can then be complemented with an adjustment tuning the height using a nut that acts by varying the definitive axial position of the inner tube.
En algunos casos, tal como en la Patente de Invención española 9700061 y 200401355, un resorte en forma de fleje doblado en "V" queda dispuesto dentro del tubo interior haciendo tope sus alas extremas en una valona de la tuerca de ajuste.In some cases, such as in the Patent of Spanish invention 9700061 and 200401355, a spring shaped "V" folded strap is arranged inside the inner tube butt its extreme wings in a walnut of the nut of adjustment.
Los puntales actualmente conocidos presentan como inconveniente el elevado precio de algunos componentes, que deben ser conseguidos por moldeo, así como los tratamientos posteriores de protección contra la oxidación, teniendo en cuenta las zonas de soldadura entre tubos y pletinas, lo cual reporta en conjunto un precio elevado del puntal y una calidad claramente mejorable.Currently known struts present as inconvenient the high price of some components, which they must be achieved by molding, as well as treatments post protection against oxidation, taking into account the welding zones between tubes and plates, which reports in set a high price of the strut and a quality clearly improvable.
Para solucionar los inconvenientes mencionados la presente invención da a conocer un nuevo tipo de puntal cuyo diseño está destinado a permitir la fabricación y montaje del puntal completo por simples métodos de deformación en frío de los metales, tal como puede ser troquelado en prensa, abocardado, acuñado, laminado de roscas en frío, montaje a presión y otros, de manera que permiten conseguir un puntal de gran resistencia, facilidad de manejo y fabricación económica. En particular, dado el diseño y forma de obtención de las diferentes piezas, se hace posible que el puntal pueda ser fabricado partiendo de piezas previamente dotadas de tratamiento superficial antioxidación, por ejemplo, cincado u otros, lo cual mejora la calidad y la economía.To solve the mentioned problems The present invention discloses a new type of strut whose Design is intended to allow the manufacture and assembly of the strut complete by simple cold deformation methods of metals, as it can be stamped in press, flared, coined, cold thread rolling, pressure mounting and others, so which allow to achieve a high resistance strut, ease of economic handling and manufacturing. In particular, given the design and way of obtaining the different pieces, it is possible that the strut can be manufactured from previously equipped parts of antioxidant surface treatment, for example, galvanized or others, which improves quality and economy.
Para lograr sus objetivos, la presente invención prevé que ambos elementos tubulares telescópicos que integran el puntal presenten pletinas extremas acopladas por roscado y bloqueadas por deformación en frío del tubo y/o de la pletina y que el tubo exterior presente en su extremo superior una zona de mayor diámetro roscada para la tuerca de ajuste longitudinal.To achieve its objectives, the present invention provides that both telescopic tubular elements that make up the strut present threaded ends and blocked by cold deformation of the tube and / or the plate and that the outer tube present at its upper end an area of greater threaded diameter for the longitudinal adjustment nut.
En particular, las pletinas inferior y superior respectivamente de ambos elementos tubulares del puntal quedarán retenidas por combinación de roscado y deformación en frío en los extremos de los propios elementos tubulares por abocardado del elemento tubular y/o acuñado de la propia pletina en las inmediaciones del orificio roscado, para producir la deformación de los hilos de rosca para lograr el bloqueo de cada pletina con su elemento tubular.In particular, the lower and upper plates respectively both strut tubular elements will remain retained by combination of threaded and cold deformation in the ends of the tubular elements themselves by flare of the tubular and / or coined element of the plate itself in the immediate vicinity of the threaded hole, to produce deformation of the threads to achieve the blocking of each plate with its tubular element
Igualmente la presente invención prevé que el elemento tubular interno presente en su parte superior una zona de diámetro igual al del elemento tubular exterior, para permitir así la utilización de la misma pletina en el extremo superior y en el extremo inferior del puntal.The present invention also provides that the internal tubular element present in its upper part an area of diameter equal to that of the outer tubular element, thus allowing the use of the same plate at the upper end and in the lower end of the strut.
Asimismo, la presente invención prevé la posibilidad de realización del extremo superior del tubo externo del puntal portador de la rosca mediante una zona de mayor diámetro sobre la que puede estar retenido un manguito portador de la rosca, que queda bloqueado axialmente por una valona o zona extrema rebordeada hacia el interior y por una zona inferior deformada conjuntamente con el tubo externo, retenida firmemente por el escalón formado conjuntamente.Also, the present invention provides for possibility of realization of the upper end of the outer tube of the thread bearing strut through a larger diameter area on which a thread bearing sleeve may be retained, which is axially blocked by a wall or extreme zone beaded inwards and by a deformed lower area together with the outer tube, held tightly by the jointly formed step.
La valona dirigida hacia adentro del manguito portador de la rosca sirve al mismo tiempo como tope axial para las aletas del resorte de tope axial que en puntales anteriores quedaban retenidas por la valona de la pieza portadora de la rosca, realizada por moldeo.The wall facing inside the sleeve thread carrier serves at the same time as an axial stop for axial stop spring fins that were left on front struts retained by the wall of the thread bearing part, made by molding.
En resumen, el puntal se caracteriza porque las uniones de las pletinas superior e inferior, así como la zona roscada intermedia y los elementos de retención a tope de ambos elementos telescópicos del puntal, están realizados por deformación en frío sin soldadura mediante elementos planos y elementos tubulares de acero previamente dotados de recubrimiento antioxidante.In summary, the strut is characterized because junctions of the upper and lower plates, as well as the area intermediate thread and the butt retaining elements of both telescopic strut elements, are made by deformation cold welding without flat elements and elements tubular steel previously provided with coating antioxidant

Las figuras 1 y 2 son respectivamente una vista en alzado de un puntal completo según la presente invención y una sección longitudinal del mismo por el plano de corte mostrado en la figura 1.Figures 1 and 2 are respectively a view in elevation of a complete strut according to the present invention and a longitudinal section thereof by the cutting plane shown in the Figure 1.
La figura 3 muestra un detalle en sección del extremo superior del puntal.Figure 3 shows a sectional detail of the upper end of the strut.
La figura 4 muestra un detalle de la realización de la parte superior del tubo externo y posición correspondiente del tubo interno con el resorte de tope.Figure 4 shows a detail of the embodiment of the upper part of the outer tube and corresponding position of the inner tube with the stop spring.
La figura 5 muestra una vista similar a la figura 4 con el resorte en posición de tope.Figure 5 shows a view similar to the Figure 4 with the spring in the stop position.
La figura 6 muestra una vista en sección de detalle de la parte superior del tubo externo junto con su pletina correspondiente.Figure 6 shows a sectional view of detail of the upper part of the outer tube together with its plate correspondent.
La figura 7 muestra una vista a mayor escala del extremo inferior del tubo externo del puntal.Figure 7 shows an enlarged view of the lower end of the outer tube of the strut.
Tal como se representa en los dibujos, el puntal comprende un elemento tubular inferior (1) y un elemento tubular superior (2) acoplado de forma telescópica en el primero, poseyendo ambos sendas pletinas extremas (3) y (4) para el apoyo del extremo inferior y del extremo superior respectivamente sobre el piso de soporte y en la estructura superior que debe ser soportada por el puntal. Un pasador intermedio (5) permite la variación de longitud del puntal aprovechando el efecto telescópico de los tubos interior y exterior y la serie de orificios longitudinales (6) del puntal interior.As depicted in the drawings, the strut it comprises a lower tubular element (1) and a tubular element upper (2) telescopically coupled in the first, possessing both extreme flat paths (3) and (4) for end support lower and upper end respectively on the floor of support and in the upper structure that must be supported by the strut. An intermediate pin (5) allows the variation of length of the strut taking advantage of the telescopic effect of the inner tubes and outside and the series of longitudinal holes (6) of the strut inside.
El elemento tubular interior (2) presenta cerca de su extremo inferior un resorte de tope en "V" (7) con patillas superiores (8) y (9), figuras 4 y 5, que atraviesan el tubo interior (2).The inner tubular element (2) has close from its lower end a "V" stop spring (7) with upper pins (8) and (9), figures 4 and 5, which cross the inner tube (2).
En la figura 3 se ha representado en mayor detalle el extremo superior del puntal en el que se aprecia que el tubo interior (2) lleva fijada la pletina superior (4) por rosca de la zona de coincidencia (10), presentando además una ligera embutición (11) para permitir que la valona superior de retención (12) del tubo interior (2) quede dispuesta al mismo nivel que la superficie correspondiente de dicha pletina (4). Por lo tanto, la pletina (4) queda retenida por acción de la rosca de la zona (10) y la valona o abocardado superior (12), es decir, por métodos que evitan por completo zonas soldadas.In figure 3 it has been represented in greater detail the upper end of the strut in which it is appreciated that the inner tube (2) has the upper plate fixed (4) by thread of the coincidence zone (10), also presenting a slight drawing (11) to allow the upper retention wall (12) of the inner tube (2) is arranged at the same level as the corresponding surface of said plate (4). Therefore, the plate (4) is retained by action of the thread of the area (10) and the walloon or upper flare (12), that is, by methods that completely avoid welded areas.
La zona del extremo superior del tubo (2) puede estar dotada de una parte ensanchada (13) con diámetro igual a la del elemento tubular inferior (1) para permitir que la pletina superior (4) sea igual que la pletina inferior (3), que se ha mostrado en mayor detalle en las figuras 6 y 7. Además, dicha parte ensanchada (13) tiene también una función de seguridad al evitar que en un eventual descenso brusco del elemento tubular interior del puntal los operarios puedan sufrir lesiones en las manos por atrapamiento con la pletina superior, puesto que el ensanchamiento forma un escalón inferior que quedará retenido en el borde superior del elemento tubular inferior del puntal.The area of the upper end of the tube (2) can be provided with a widened part (13) with a diameter equal to the of the lower tubular element (1) to allow the plate upper (4) is the same as the lower plate (3), which has been shown in greater detail in figures 6 and 7. Furthermore, said part widened (13) also has a safety function by avoiding that in an eventual abrupt descent of the inner tubular element from the prop the operators may suffer injuries to their hands due to entrapment with the upper plate, since the widening form a lower step that will be retained at the upper edge of the lower tubular element of the strut.
La parte superior ensanchada (13) del tubo interno (2) tendrá una longitud variable, si bien de forma general podrá ser de unos 100 mm o superior.The widened upper part (13) of the tube internal (2) will have a variable length, although in general It may be about 100 mm or more.
En la figura 7 se ha representado en mayor detalle la pletina inferior (3) del tubo externo (1) que, tal como se ha indicado, podrá ser igual a la pletina superior (4) del tubo interno (2).In figure 7 it has been represented in greater detail the lower plate (3) of the outer tube (1) which, such as indicated, may be equal to the upper plate (4) of the tube internal (2).
La retención de la pletina en el extremo inferior del tubo (1) se realizará de igual forma que para la pletina superior (4), existiendo la zona roscada (14) entre el tubo y la pletina y la valona o abocardado (15) del elemento tubular para la retención de la pletina. Para incrementar la retención de la pletina en el elemento tubular evitando el desenroscado, se puede recurrir a una operación de acuñado de la pletina en la zona superior de la misma, inmediata a la rosca (14), provocando un rehundido periférico, continuo o no, -16- que al deformar los hilos de la rosca (14) aumentará la retención de la pletina (3). Como es evidente, igual método de retención u otros podrán ser utilizados en la pletina superior (4).The retention of the plate at the end The bottom of the tube (1) will be made in the same way as for the upper plate (4), the threaded area (14) existing between the tube and the plate and the wall or flare (15) of the tubular element for retention of the plate. To increase the retention of plate in the tubular element avoiding unscrewing, you can resort to a coining operation of the plate in the area superior of the same, immediately to the thread (14), causing a recessed peripheral, continuous or not, -16- that when deforming the threads of the thread (14) will increase the retention of the plate (3). How is it Obviously, the same retention method or others may be used on the top plate (4).
La presente invención prevé que el tubo externo (1) presente una zona roscada (17) para la tuerca (18) de ajuste fino en altura. Para ello la presente invención prevé que la parte superior del tubo externo (1) tenga un diámetro algo mayor para permitir el laminado de la rosca (17), pudiéndose realizar en la práctica dicha disposición mediante el montaje de un casquillo externo (19) que se acopla íntimamente a la parte superior ensanchada (20) del elemento tubular (1), efectuándose la deformación conjunta de ambos elementos (1) y (19) para formar la zona ensanchada (20) así como el escalón inferior (21) y la valona superior (22) dirigida hacia adentro. De esta manera se logra una íntima unión entre el casquillo (19) y el elemento tubular (1) con un resistente tope axial y acción de retención radial. Al propio tiempo, la valona (22) está destinada a servir de tope a las patillas (8) y (9) del resorte en "V" (7) tal como se ha representado en la figura 5.The present invention provides that the outer tube (1) present a threaded area (17) for the adjusting nut (18) fine in height. For this purpose the present invention provides that the part upper outer tube (1) has a somewhat larger diameter to allow the rolling of the thread (17), being able to be carried out in the practice said arrangement by mounting a bushing external (19) that fits intimately to the top widened (20) of the tubular element (1), the joint deformation of both elements (1) and (19) to form the widened area (20) as well as the lower step (21) and the wall superior (22) directed inwards. This way you achieve a intimate connection between the bushing (19) and the tubular element (1) with a resistant axial stop and radial retention action. To own time, the Walloon (22) is intended to serve as a stop to the pins (8) and (9) of the "V" spring (7) as it has been represented in figure 5.
