TAPON PARA CERRAMIENTO DE ORIFICIOS EN PAREDES PLUG FOR CLOSURE OF WALL HOLES
Y SIMILARESAND SIMILAR
DESCRIPCIÓNDESCRIPTION
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un tapón para cerramiento de orificios en paredes o similares, previsto preferente y fundamentalmente para su aplicación en muros de hormigón. El tapón está constituido por un cuerpo flexible, preferentemente de elastómero, que en su montaje y fijación se adapta perfectamente al orificio para conseguir una obturación óptima de éste, con ayuda de un útil de agarre y traccionado del propio tapón.The present invention relates to a plug for closing holes in walls or the like, preferably provided and mainly for application in concrete walls. The plug is constituted by a flexible body, preferably made of elastomer, which in its assembly and fixation adapts perfectly to the hole to achieve an optimum sealing of the latter, with the help of a tool for gripping and pulling the cap itself.
El objeto de la invención es proporcionar al sector de la construcción un tapón mediante el que se garantiza la impermeabilización y cerramiento de los huecos u orificios originados en los muros de hormigón, como consecuencia del proceso de encofrado del mismo.The object of the invention is to provide the construction sector with a plug whereby the waterproofing and closing of the gaps or holes originated in the concrete walls is guaranteed, as a consequence of the formwork process thereof.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, los paneles de encofrado que se disponen para la formación de muros de hormigón, se relacionan y se sujetan paralelamente entre sí mediante bulones transversales con sus extremos roscados y sobresalientes al exterior de los paneles, para recibir el roscado de correspondientes tuercas, todo ello en orden a soportar la carga del hormigón e impedir obviamente la separación de dichos paneles de encofrado.As it is known, the formwork panels that are arranged for the formation of concrete walls, are related and held parallel to each other by transverse bolts with their threaded ends and protruding to the outside of the panels, to receive the threading of corresponding nuts, all in order to support the load of the concrete and obviously prevent the separation of said formwork panels.
Pues bien, la retirada de tales paneles una vez fraguado el hormigón y la extracción de los bulones, da lugar a que queden los correspondientes orificios en el muro de hormigón, orificios que si bien no afectan en absoluto a la rigidez estructural del muro, sin embargo crean problemas de transmisión de humedades, sobre todo cuando se sitúan en zonas enterradas de los muros, o cuando éstos se utilizan como elementos de contención de tierras. Como es lógico, para evitar esos problemas se lleva a cabo el tapado u obturación de los orificios en cuestión, utilizando actualmente tapones de plástico o silicona que estéticamente cierran el hueco u orificio pero no garantizan la impermeabilidad.Well, the removal of such panels once the concrete has set and the removal of the bolts, results in the corresponding holes in the concrete wall, holes that while not affecting the structural rigidity of the wall at all, without However, they create moisture transmission problems, especially when they are located in buried areas of the walls, or when they are used as land containment elements. Naturally, to avoid these problems, the covering or sealing of the holes in question is carried out, currently using plastic or silicone plugs that aesthetically close the hole or hole but do not guarantee impermeability.
Además, para la sujeción de dicho tipo de tapones se utiliza adhesivo, y para intentar garantizar la estanqueidad se aplica posteriormente mortero.In addition, adhesive is used to secure this type of plug, and mortar is applied to try to guarantee the sealing.
Como es evidente, el proceso de taponado referido para intentar garantizar un cierre eficaz e impermeable, conlleva varias fases operativas y la aplicación de varios componentes por separado, lo cual no deja de ser laborioso, lento y en definitiva costoso.As it is evident, the process of corking referred to try to guarantee an effective and waterproof closure, involves several operational phases and the application of several components separately, which is still laborious, slow and ultimately expensive.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El tapón que se preconiza, ha sido concebido para resolver la problemática anteriormente expuesta, basándose en una solución sencilla pero de gran eficacia. Más concretamente, el tapón de la invención presenta la particularidad de constituirse a partir de un cuerpo flexible de sección circular, que puede ser cilindrico o tronco-cónico, afectado de un orificio o paso axial en el que se monta un vastago rígido o semirrígido con filete de rosca en diente de sierra, o alternativamente un remache convencional. -The plug that is recommended has been designed to solve the problem described above, based on a simple but highly effective solution. More specifically, the cap of the invention has the particularity of being constituted from a flexible body of circular section, which can be cylindrical or conical trunk, affected by an orifice or axial passage in which a rigid or semi-rigid rod is mounted with Sawtooth thread steak, or alternatively a conventional rivet. -
Dicho vastago roscado presenta en uno de sus extremos una cabeza de tope contra el extremo del cuerpo flexible, mientras que el extremo opuesto es tronco-cónico o agudizado y emerge al exterior a través del otro extremo del citado cuerpo flexible, contando en este extremo con una arandela de tope rígida o semirrígida.Said threaded rod has at one of its ends a stopper head against the end of the flexible body, while the opposite end is conical or sharpened trunk and emerges to the outside through the other end of said flexible body, counting on this end with a rigid or semi-rigid butt washer.
Ei cuerpo flexible, con el vastago y la arandela, forman un conjunto único que se introduce en el orificio o paso a tapar, de manera que mediante un útil apropiado, como puede ser una remachadora, se tracciona del extremo agudizado del vastago, produciendo el desplazamiento del mismo y por tanto la contracción del cuerpo flexible entre la referida cabeza del vastago y la arandela, contracción que conlleva la expansión del propio cuerpo flexible y con ello el ajuste sobre el orificio, produciendo el sellado de éste.The flexible body, with the rod and the washer, forms a unique assembly that is introduced into the hole or step to be covered, so that by an appropriate tool, such as a riveter, it is pulled from the sharpened end of the rod, producing the displacement of the same and therefore the contraction of the flexible body between the said head of the rod and the washer, contraction that entails the expansion of the flexible body itself and with it the adjustment on the hole, producing its sealing.
La rosca en diente de sierra permite que la arandela salte sobre los dientes del vastago sin necesidad de girar, durante la operación de traccionado, permitiendo precisamente la contracción y correspondiente expansión del cuerpo flexible. Sin embargo, ese dentado permite el giro del vastago para efectuar el desmontaje.The sawtooth thread allows the washer to jump over the teeth of the rod without turning, during the traction operation, allowing precisely the contraction and corresponding expansion of the flexible body. However, this gear allows the rotation of the rod to carry out the disassembly.
Preferentemente, la arandela presenta un diámetro menor que el del cuerpo flexible, aunque en una variante de realización la arandela presenta un diámetro mayor que el del cuerpo flexible y por tanto mayor que el orificio o paso en el que se aplique, constituyendo entonces un tope contra la embocadura de tal orificio, siendo la forma de llevar a efecto la expansión del cuerpo flexible la misma, efectuando finalmente el seccionado del tramo sobrante del vastago, como ocurre en el montaje o fijación de remaches convencionales.Preferably, the washer has a diameter smaller than that of the flexible body, although in a variant embodiment the washer has a diameter greater than that of the flexible body and therefore greater than the hole or passage in which it is applied, thus constituting a stop against the mouth of such a hole, the way of carrying out the expansion of the flexible body being the same, finally sectioning the section leftover of the rod, as occurs in the assembly or fixing of conventional rivets.
En otra variante de realización del tapón, el cuerpo flexible, es acusadamente tronco -cónico, hueco y dotado de un tramo extremo con un paso por el que pasa el vastago. En este tramo extremo va situada la arandela y en el opuesto y abierto se sitúa la cabeza del tornillo, en este caso tronco-cónica, para favorecer la expansión del propio cuerpo flexible.In another embodiment of the cap, the flexible body is markedly trunk-conical, hollow and endowed with an end section with a passage through which the stem passes. In this extreme section the washer is located and in the opposite and open is the screw head, in this case trunk-conical, to favor the expansion of the flexible body itself.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNFigure 4.- Shows a side elevation of the cap in a second embodiment in which the washer is larger in diameter than the flexible body. PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como el tapón de la invención se constituye mediante la asociación de tres elementos, como 5 se representa en las figuras 1, 2 y 3, uno de ellos formado por un cuerpo flexible 1, preferentemente de material elastomérico, estando éste afectado de un paso u orificio axial (2), siendo el cuerpo (1) de configuración cilindrica o tronco-cónica.In view of the figures outlined, it can be seen how the cap of the invention is constituted by the association of three elements, as 5 is represented in Figures 1, 2 and 3, one of them formed by a flexible body 1, preferably of material elastomeric, being affected by an axial passage or hole (2), the body (1) being cylindrical or conical-shaped.
El segundo elemento que interviene en la constitución del tapón 0 corresponde a un vastago roscado (3) con un filete de rosca (4) en diente de sierra, vastago (3) que presenta uno de sus extremos dotado de una cabeza (5) y en el extremo opuesto rematado de forma agudizada (6), de manera tal que ese vastago (3) está previsto para alojarse en el orificio o paso (2) del cuerpo flexible (1), haciendo tope la cabeza (5) en uno de los extremos del cuerpo (1), 5 mientras que el extremo agudizado (6) aflora al exterior del extremo opuesto, previo paso a través de una arandela (7) constitutiva del tercer elemento del tapón, arandela que hace tope sobre el propio extremo del cuerpo flexible (1).The second element involved in the constitution of the plug 0 corresponds to a threaded rod (3) with a thread fillet (4) in a sawtooth, rod (3) having one of its ends provided with a head (5) and at the opposite end sharpened (6), so that this rod (3) is intended to be housed in the hole or passage (2) of the flexible body (1), butting the head (5) in one of the ends of the body (1), 5 while the sharpened end (6) emerges to the outside of the opposite end, after passing through a washer (7) constituting the third element of the stopper, washer that stops over the end of the flexible body (1).
El tapón constituido de la manera descrita y mostrada claramente en la figura 2, se introduce en el orificio o paso del muro de hormigón, y C) mediante el traccionado a través del extremo agudizado (6) por medio de una remachadora o útil similar, realizar una contracción del cuerpo flexible (1), y por consiguiente una expansión radial de éste, ajustándose sobre el orificio del muro de hormigón, sellando el mismo. El dentado en dientes sierra (4) permite el salto de la arandela (7) sin necesidad de girar el vastago (3), mientras que en un sentido de giro determinado es posible llevar a cabo el desmontaje al realizarse un desenroscado entre cuerpos.The plug constituted in the manner described and clearly shown in Figure 2, is introduced into the hole or passage of the concrete wall, and C) by means of the traction through the sharpened end (6) by means of a riveter or similar tool, perform a contraction of the flexible body (1), and consequently a radial expansion thereof, adjusting over the hole in the concrete wall, sealing it. The serrated teeth saw (4) allows the jump of the washer (7) without the need to rotate the rod (3), while in a certain direction of rotation it is possible to carry out the disassembly when unscrewing between bodies.
En una variante de realización mostrada en la figura 4, se ha previsto que la arandela (7') sea de mayor diámetro que el cuerpo (1) y por tanto que el del orificio en el que ha de alojarse ese cuerpo (1), por lo que tal arandela (7') hace tope contra Ia embocadura del orificio del muro de hormigón, realizándose la fijación de igual manera que a como anteriormente se ha dicho, es decir, por traccionado a través del extremo agudizado (6) del vastago (2) y realizar, una vez expandido y ajustado el cuerpo flexible (1) sobre el orificio del muro de hormigón, el seccionado de la parte sobrante del vastagoIn a variant embodiment shown in Figure 4, it is provided that the washer (7 ') is larger in diameter than the body (1) and by so much so that the hole in which that body is to be housed (1), so that such a washer (7 ') stops against the mouth of the hole in the concrete wall, fixing it in the same way as before said, that is, by pulling through the sharpened end (6) of the rod (2) and, after expanding and adjusting the flexible body (1) over the hole in the concrete wall, the sectioning of the remaining part of the rod
(2), como es convencional en el montaje de remaches mediante remachadoras.(2), as is conventional in the assembly of rivets by riveters.
Por otro lado, cabe también la posibilidad de que el cuerpo (1), en lugar de ser cilindrico o ligeramente tronco-cónico, sea acusadamente tronco- cónico y hueco, estableciéndose un paso en uno de sus extremos, el de menor diámetro, para el vastago (2), incorporando en ese extremo y externamente la correspondiente arandela, mientras que en el extremo opuesto, que es abierto, se posiciona la cabeza del vastago que será tronco-cónica para que al traccionar de éste se favorezca la expansión del propio cuerpo tronco-cónico y flexible. On the other hand, it is also possible that the body (1), instead of being cylindrical or slightly truncated-conical, is markedly conical and hollow, establishing a passage at one of its ends, the one of smaller diameter, to the rod (2), incorporating at that end and externally the corresponding washer, while at the opposite end, which is open, the head of the rod that will be trunk-conical is positioned so that when it is pulled it favors the expansion of the proper trunk-conical and flexible body.
