Description

Puntal de obra con dispositivo de refuerzo Construction strut with reinforcement device

La presente invención se refiere a un puntal de obra con un dispositivo de refuerzo que proporciona un refuerzo en la resistencia al pandeo del puntal. The present invention relates to a construction strut with a reinforcing device that provides a reinforcement in the buckling resistance of the strut.

Un puntal de obra es un elemento telescópico que se utiliza como soporte temporal de estructuras durante trabajos de construcción o reparación de estructuras o en situaciones en las que existe el riesgo de que una estructura colapse, entre otras aplicaciones. Por ejemplo, los puntales de obra se pueden utilizar para soportar las paredes de un molde de enconfrado hasta que el hormigón se haya endurecido y se puedan retirar las paredes del molde. A construction strut is a telescopic element that is used as a temporary support for structures during construction work or repair of structures or in situations where there is a risk that a structure will collapse, among other applications. For example, construction struts can be used to support the walls of a mold for a concrete until the concrete has hardened and the walls of the mold can be removed.

Habitualmente, un puntal de obra comprende dos tubos telescópicos, es decir, un tubo interior que se puede desplazar por el interior de un tubo exterior y un sistema de fijación de los tubos interior y exterior entre sí. Dicho sistema de fijación consiste habitualmente en una pluralidad de parejas de agujeros distribuidos a lo largo de la longitud del tubo interior dispuestos en posiciones diametralmente opuestas y de una pieza de fijación que atraviesa una de las citados parejas de agujeros para imposibilitar el movimiento relativo entre los tubos exterior e interior. Mediante la pieza de fijación se regula discretamente la extensión del puntal. Para el ajuste fino de la extensión del puntal, el tubo exterior comprende en su extremo superior una tuerca sobre la que queda apoyada la pieza de fijación. Usually, a construction strut comprises two telescopic tubes, that is, an inner tube that can be moved inside an outer tube and a system for fixing the inner and outer tubes to each other. Said fixing system usually consists of a plurality of pairs of holes distributed along the length of the inner tube arranged in diametrically opposite positions and of a fixing piece that passes through one of said pairs of holes to prevent relative movement between the outer and inner tubes. The extension of the strut is discretely regulated by means of the fixing piece. For fine adjustment of the extension of the strut, the outer tube comprises at its upper end a nut on which the fixing piece is supported.

La versatilidad que aporta la longitud regulable permite que los puntales de obra abarquen un gran rango de longitudes, siendo su longitud máxima aquella en la que el tubo interior se ha extraído el máximo del tubo exterior. Sin embargo, cuanto mayor es la longitud del puntal durante su uso, menor es su resistencia al pandeo, existiendo el riesgo de que el puntal colapse y cese de efectuar su función estructural cuando opera con longitudes cercanas a su longitud máxima. Por otro lado, cargas elevadas pueden provocar también el pandeo del puntal aunque su longitud no sea cercana a su longitud máxima. Para garantizar la integridad estructural del puntal de obra en estos casos, la única solución existente consiste en aumentar el número de puntales para repartir la carga que soporta cada puntal. Como resultado, el coste del uso de puntales de obra se incrementa al necesitar un mayor número de puntales de obra y, también, por conllevar un mayor tiempo de instalación y retirada de los mismos. The versatility provided by the adjustable length allows the construction struts to cover a wide range of lengths, its maximum length being that in which the inner tube has been removed the maximum from the outer tube. However, the greater the length of the strut during use, the lower its resistance to buckling, with the risk that the strut collapses and ceases to perform its structural function when it operates with lengths close to its maximum length. On the other hand, high loads can also cause the buckling of the strut even if its length is not close to its maximum length. To guarantee the structural integrity of the work strut in these cases, the only existing solution is to increase the number of struts to distribute the load that supports each strut. As a result, the cost of the use of construction struts is increased by the need for a greater number of construction struts and, also, for a longer installation and removal time.

La presente invención pretende solucionar los problemas anteriormente citados de los puntales de obra. En particular, la presente invención da a conocer un puntal de obra que comprende dos tubos telescópicos, formados por un tubo exterior y un tubo interior, y una pieza de fijación de los tubos exterior e interior entre sí, comprendiendo el tubo exterior una tuerca de ajuste en su extremo superior, siendo el tubo interior susceptible de desplazarse por el interior del tubo exterior y comprendiendo dicho tubo interior una pluralidad de parejas de agujeros distribuidos a lo largo de su longitud, estando los agujeros de dichas parejas de agujeros dispuestos en posiciones diametralmente opuestas del tubo interior, atravesando dicha pieza de fijación una de las citadas parejas de agujeros del tubo interior para impedir el movimiento relativo entre los tubos exterior e interior, caracterizado por disponer de un dispositivo de refuerzo, comprendiendo dicho dispositivo de refuerzo un manguito tubular susceptible de deslizarse por el exterior del tubo interior del puntal de obra y comprendiendo dicho manguito tubular medios de fijación al puntal de obra. The present invention aims to solve the aforementioned problems of work props. In particular, the present invention discloses a construction strut comprising two telescopic tubes, formed by an outer tube and an inner tube, and a fixing piece of the outer and inner tubes with each other, the outer tube comprising a nut of adjustment at its upper end, the inner tube being able to move inside the outer tube and said inner tube comprising a plurality of pairs of holes distributed along its length, the holes of said pairs of holes being arranged in diametrically positions opposite the inner tube, said fixing piece passing through one of said pairs of holes in the inner tube to prevent relative movement between the outer and inner tubes, characterized by having a reinforcing device, said reinforcing device comprising a susceptible tubular sleeve of sliding outside the inner tube of the work strut and understood said tubular sleeve said fixing means to the work strut.

Es también objeto de la presente invención un dispositivo de refuerzo para el citado puntal de obra caracterizado por comprender un manguito tubular susceptible de deslizarse por el exterior del tubo interior del puntal de obra y comprendiendo dicho manguito tubular medios de fijación al puntal de obra. Asimismo, otro objeto de la presente invención es el uso del citado dispositivo de refuerzo en un puntal para obras para reforzar la resistencia al pandeo del puntal. The object of the present invention is also a reinforcement device for said work strut characterized by comprising a tubular sleeve capable of sliding outside the inner tube of the work strut and said tubular sleeve comprising means for fixing to the work strut. Likewise, another object of the present invention is the use of said reinforcement device in a construction strut to reinforce the buckling resistance of the strut.

El puntal de obra objeto de la presente invención presenta una resistencia al pandeo reforzada gracias al dispositivo de refuerzo, aumentando la carga necesaria para que el puntal colapse por pandeo. De esta manera, el puntal de obra objeto de la presente invención garantiza la estabilidad y seguridad de una estructura ante cargas axiales elevadas con un menor número de puntales en comparación con puntales de obra que no comprendan el citado dispositivo de refuerzo. En consecuencia, al requerir menor cantidad de puntales de obra, el tiempo de instalación y retirada de los puntales es menor y su coste más económico. The work strut object of the present invention has a reinforced buckling resistance thanks to the reinforcement device, increasing the load necessary for the strut to collapse by buckling. In this way, the work strut object of the present invention guarantees the stability and safety of a structure against high axial loads with a smaller number of struts compared to work struts that do not comprise said reinforcement device. Consequently, by requiring less amount of construction struts, the installation and removal time of the struts is less and its cost more economical.

Por otro lado, el dispositivo de refuerzo objeto de la presente invención requiere poco tiempo de colocación puesto que simplemente se debe deslizar el manguito tubular por el exterior del tubo interior del puntal y fijarlo al puntal de obra. Además, la longitud del dispositivo de refuerzo permite incluso el transporte del puntal sin la necesidad de extraer dicho dispositivo de refuerzo, por lo que el puntal y su dispositivo se pueden trasportar y almacenar sin separarse, evitando la necesidad de colocar el dispositivo de refuerzo en el puntal antes de cada uso. De todos modos, en el caso de ser necesario, el dispositivo de refuerzo se puede extraer también de forma sencilla y rápida, liberándolo del puntal y deslizándolo por el exterior del tubo interior hacia fuera. On the other hand, the reinforcement device object of the present invention requires little installation time since the tubular sleeve must simply be slid outside the inner tube of the strut and fixed to the work strut. In addition, the length of the reinforcement device even allows the strut to be transported without the need to remove said reinforcement device, whereby the strut and its device can be transported and stored without separating, avoiding the need to place the reinforcement device in the strut before each use. However, if necessary, the reinforcement device can also be removed easily and quickly, releasing it from the strut and sliding it outside the inner tube outwards.

En una realización del puntal de obra objeto de la presente invención, los medios de fijación del manguito tubular al puntal comprenden una pareja de agujeros dispuestos en posiciones diametralmente opuestas del manguito tubular de manera que la pieza de fijación atraviesa la pareja de agujeros del manguito tubular para fijarlo al puntal de obra. De esta manera la pieza de fijación de los tubos interior y exterior entre sí atraviesa también los agujeros del manguito tubular, quedando el manguito tubular fijado al puntal de obra. In an embodiment of the work strut object of the present invention, the fixing means of the tubular sleeve to the strut comprise a pair of holes arranged in diametrically opposite positions of the tubular sleeve so that the fixing piece passes through the pair of holes of the tubular sleeve to fix it to the work strut. In this way, the fixing part of the inner and outer tubes also passes through the holes of the tubular sleeve, the tubular sleeve being fixed to the work post.

De forma opcional, el manguito tubular queda en contacto con la tuerca de ajuste del extremo superior del tubo exterior del puntal. En esta posición el posible movimiento angular entre los tubos interior y exterior del puntal de obra debido a cargas queda minimizado. Optionally, the tubular sleeve is in contact with the adjusting nut of the upper end of the outer tube of the strut. In this position the possible angular movement between the inner and outer tubes of the work strut due to loads is minimized.

Preferentemente, el manguito tubular comprende una aleta perimetral en uno de sus extremos. De esta manera, en caso de que haya contacto entre el manguito tubular y la tuerca de ajuste del tubo exterior del puntal, la superficie de contacto es mayor, de forma que las tensiones y esfuerzos generados son menores. Además, la aleta facilita el manejo manual del dispositivo y ayuda a alinear ambos tubos del puntal. Preferably, the tubular sleeve comprises a perimeter fin at one of its ends. Thus, if there is contact between the tubular sleeve and the adjustment nut of the outer tube of the strut, the contact surface is larger, so that the stresses and stresses generated are lower. In addition, the flap facilitates manual operation of the device and helps align both strut tubes.
