Description

Cierre para bovedillas.Closure for vaults.

Object of the invention

La presente invención se refiere a un cierre para bovedillas, de las utilizadas en el ámbito de la construcción para la elaboración de forjados, teniendo como finalidad dicho cierre evitar el acceso del hormigón al interior de las bovedillas, durante la maniobra de vertido del mismo.The present invention relates to a closure for vaults, of those used in the field of construction for the elaboration of floor slabs, having said purpose Close prevent the access of concrete to the inside of the vaults, during the pouring maneuver.

El objeto de la invención es asegurar una perfecta estabilidad de la tapa que participa en dicho cierre, con respecto a la complementaria bovedilla, frente a agentes externos tales como lluvia, viento, etc.The object of the invention is to ensure a perfect stability of the lid that participates in said closure, with regarding the complementary vault, compared to external agents such as rain, wind, etc.

Background of the invention

Un sistema habitual en el ámbito de la construcción de forjados, es la utilización de bovedillas, generalmente cerámicas, que se disponen formando alineaciones que definen entre ellas calles en las que se introducen armaduras metálicas y en las que posteriormente se vierte el hormigón, de manera que las bovedillas actúan como medios aligerantes del forjado y como encofrados para la formación de las vigas a expensas del citado hormigón armado.A usual system in the field of Forged construction, is the use of vaults, generally ceramics, which are arranged forming alignments that define between them streets in which armor is introduced metal and in which the concrete is subsequently poured, of so that the vaults act as lightening means of forged and as formwork for the formation of beams at the expense of the aforementioned reinforced concrete.

Dichas bovedillas adoptan una estructuración tubular, con tabiques rigidizadores internos, y están abiertas por sus caras de adaptación entre bovedillas, de manera que en el extremo de cada alineación la última bovedilla queda abierta, y en la posterior operación de vertido del hormigón éste penetra en el seno de la misma. Dado que tras el vertido del hormigón este debe de ser vibrado, la cantidad del mismo que penetra en las bovedillas es importante, lo que supone una problemática con una doble vertiente, por un lado se produce un consumo innecesario de hormigón y por otro se carga el forjado con un peso indeseable.These vaults adopt a structuring tubular, with internal stiffeners, and are open by their faces of adaptation between vaults, so that in the end of each alignment the last vault is open, and in the subsequent operation of concrete pouring it penetrates the bosom of it. Since after the pouring of concrete it must if vibrated, the amount of it penetrates the vaults It is important, which is a problem with a double slope, on the one hand there is an unnecessary consumption of concrete and on the other the floor is loaded with an undesirable weight.

Tratando de resolver este problema son conocidas tapas, generalmente de cartón, de forma dimensionalmente coincidente con el perfil de las bovedillas, que aplicadas a las bovedillas terminales impiden que el hormigón penetre en el seno de las mismas.Trying to solve this problem are known lids, usually cardboard, dimensionally coinciding with the profile of the vaults, which applied to the terminal vaults prevent concrete from penetrating into the same.

El propio solicitante es titular del modelo de utilidad U 200700095 donde se describe una tapa de cartón para bovedillas que además de cumplir la función descrita, permite ser acoplada a bovedillas de diferentes tamaños, mediante troquelados a distintas alturas que posibilitan su fragmentación y consecuente coincidencia dimensional con el tipo de bovedillas utilizado en cada momento.The applicant himself owns the model of utility U 200700095 where a cardboard lid is described for vaults that in addition to fulfilling the described function, allows to be coupled to vaults of different sizes, through die cut different heights that enable fragmentation and consequent dimensional coincidence with the type of vaults used in every moment

Sin embargo, tanto las tapas convencionales como la de este modelo de utilidad, presentan problemas de fijación a la bovedilla ya que utilizan al efecto pestañas laterales plegables que penetran en el seno de la bovedilla, actuando como medios de fijación a esta última.However, both conventional caps and that of this utility model, present problems of fixation to the vault since they use folding side flanges that penetrate into the vault, acting as means of fixing to the latter.

Esta solución si bien resulta plenamente satisfactoria desde el punto de vista teórico, en la práctica presenta frecuentemente problemas, sobre todo cuando transcurre un periodo de tiempo relativamente importante entre el momento de implantación de las tapas y el momento del vertido de hormigón, ya que el cartón pierde su elasticidad cuando se moja, de manera que ante una situación de lluvia la fijación queda prácticamente anulada y las tapas se desprenden con facilidad. Lo mismo sucede en situaciones de viento mas o menos fuerte.This solution although it is fully satisfactory from a theoretical point of view, in practice frequently presents problems, especially when a relatively important period of time between the time of implantation of the covers and the moment of concrete pouring, since that the cardboard loses its elasticity when it gets wet, so that in a rainy situation the fixation is practically canceled and the covers come off easily. The same happens in wind situations more or less strong.

Description of the invention

El cierre para bovedillas que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta.The closing for vaults that the invention proposes to solve the problem fully satisfactorily previously exposed.

Para ello y a partir de la estructuración de una tapa convencional o de una tapa como la del modelo de utilidad U 200700095, la invención consiste en dotar a dicha tapa, que puede ser de cartón, de plástico u otro material apropiado de reducido costo, incorpora en puntos estratégicamente distribuidos de la misma, parejas de ventanas destinadas a enmarcar a cualquiera de los tabiquillos interiores de la bovedilla, de manera que dichas ventanas definen entre sí una especie de pequeño listón de cartón sobrepuesto al borde libre del tabique seleccionado de la bovedilla.For this and from the structuring of a conventional cover or a cover like the utility model U 200700095, the invention consists in providing said cover, which can be of cardboard, plastic or other appropriate reduced material cost, incorporates in strategically distributed points of the same, pairs of windows intended to frame any of the interior partitions of the vault, so that windows define each other a kind of small cardboard strip superimposed on the free edge of the selected partition of the vault

Como complemento para esta estructura de la tapa, en el cierre participan una pluralidad de pinzas de un material elástico, de perfil en U, capaces de acoplarse a presión sobre los laterales del correspondiente tabiquillo y a retener a través de su zona media la tapa, concretamente el listón de la misma definido por la pareja de ventanas.As a complement to this structure of the lid, a plurality of tweezers of a elastic material, U-profile, capable of snap coupling on the sides of the corresponding partition and to retain through its middle area the lid, specifically the ribbon of the same defined by the pair of windows.

Obviamente cuando se trate de una fijación marginal de la tapa existirá una ventana única para paso de una de las ramas laterales de la pinza, ya que la otra rama lateral se adaptará tanto al borde correspondiente de la tapa como a la pared lateral externa del tabique marginal de la bovedilla.Obviously when it is a fixation marginal from the lid there will be a single window to pass one of the lateral branches of the clamp, since the other lateral branch is will adapt both to the corresponding edge of the lid and to the wall outer side of the marginal vault wall.

De acuerdo con otra de las características de la invención se ha previsto que las citadas pinzas presenten sus ramas laterales asimétricas, para facilitar su montaje sobre la tapa y sobre la propia bovedilla.According to another of the characteristics of the invention it is provided that said pliers have their branches asymmetric sides, for easy mounting on the lid and on the vault itself.

Finalmente y de acuerdo con otra de las características de la invención se ha previsto también que las ramas laterales de la pinza presenten su borde libre acodado ortogonalmente hacia dentro, determinando una estrangulación de su embocadura que potencia el efecto de agarre sobre el tabique correspondiente de la bovedilla.Finally and according to another of the characteristics of the invention it is also provided that the lateral branches of the clamp have their free edge bent orthogonally inward, determining a strangulation of its mouthpiece that enhances the gripping effect on the septum corresponding of the vault.

Preferred Embodiment of the Invention

En las figuras reseñadas se ha representado esquemáticamente una bovedilla (1) a la que es aplicable el cierre de la invención, bovedilla materializada en un cuerpo tubular, que se corresponde con la propia referencia (1), rigidizada mediante una pluralidad de tabiquillos interiores (2) convenientemente distribuidos.In the figures outlined it has been represented schematically a vault (1) to which the closure is applicable of the invention, vault materialized in a tubular body, which corresponds to the reference itself (1), stiffened by a plurality of interior partitions (2) conveniently distributed.

Pues bien, el cierre que la invención propone se materializa en una lámina (3) de cartón o similar, de contorno y dimensiones adecuadas para cerrar todos los alvéolos (4) definidos en la bovedilla (1) por los tabiquillos (2), y preferentemente dotada de líneas de troquelado (5) que, mediante rasgado, permiten regular a voluntad la altura efectiva de la tapa para adecuarla a distintos tamaños de bovedilla (1).Well, the closure proposed by the invention is materializes in a sheet (3) of cardboard or similar, contour and dimensions suitable for closing all defined alveoli (4) in the vault (1) by the partitions (2), and preferably equipped with die cut lines (5) that, by tearing, allow regulate at will the effective height of the lid to adapt it to different sizes of vault (1).

Pues bien, de acuerdo ya con la invención, la citada tapa, que puede incorporar las clásicas pestañas (6) que acodadas ortogonalmente con respecto al plano general de la tapa pueden penetrar ajustadamente en los alvéolos marginales y correspondientes (4), centra su característica en la incorporación de parejas de pequeñas ventanas (7), que definen en el seno de cada una de ellas una especie de estrecho listón (8), de anchura coincidente con el espesor de los tabiquillos compartimentadores (2) de la bovedilla, aunque admite ligeras diferencias dimensionales tanto en sentido positivo como en sentido negativo, estando dichos listones (8) destinados a quedar enfrentados a los repetidamente citados tabiquillos (2), y complementándose cada uno de estos listones o parejas de ventanas (7) con una pinza o grapa (9), de configuración en "U", cuyas ramas laterales están destinadas a pasar a través de las ventanas (7) y a pinzar elásticamente el tabiquillo (2) correspondiente de la bovedilla (1), consiguiéndose de esta manera una fijación estable para la tapa (3), que se mantiene inalterada frente a agentes ambientales como lluvia, viento, etc.Well, according to the invention, the cited cover, which can incorporate the classic tabs (6) that orthogonally angled with respect to the general plane of the lid can penetrate tightly into the marginal alveoli and corresponding (4), focuses its feature on incorporation of pairs of small windows (7), which define within each one of them a kind of narrow ribbon (8), wide coinciding with the thickness of the partition compartments (2) of the vault, although it admits slight differences dimensional both positively and negatively, said slats (8) being intended to face the repeatedly cited partitions (2), and complementing each of these slats or pairs of windows (7) with a clamp or staple (9), "U" configuration, whose lateral branches are intended to pass through the windows (7) and to clamp elastically the corresponding partition (2) of the vault (1), thus achieving a stable fixation for the lid (3), which remains unchanged against environmental agents like rain, wind, etc.

En el ejemplo de realización práctica representado en la figura 1, las parejas de ventanas (7) se sitúan en disposición sensiblemente centrada con respecto a la tapa (3), pero pueden existir complementariamente ventanas marginales como la referenciada con (7'), ventanas que son unitarias por cuanto que la grapa (9) correspondiente se adapta exteriormente bien a los bordes de la tapa (3) o bien a las pestañas (6) prolongación acodada de la misma.In the example of practical realization represented in figure 1, the pairs of windows (7) are placed in substantially centered arrangement with respect to the cover (3), but there may be complementary marginal windows such as referenced with (7 '), windows that are unitary because the corresponding clip (9) fits externally well to the edges from the cover (3) or to the tabs (6) elongated extension of the same.

Volviendo nuevamente a las pinzas o grapas (9) éstas estarán obtenidas a partir de un material elásticamente deformable, como por ejemplo acero o un plástico apropiado, y presentan además la particularidad de que sus ramas laterales (10), (10') son asimétricas, es decir una de ellas es sustancialmente mas larga que la otra, como se observa especialmente en la figura 3, en orden a facilitar su montaje con el conjunto constituido por la tapa (3) y el tabique (2) de la bovedilla (1).Going back to the tweezers or staples (9) these will be obtained from an elastically material deformable, such as steel or an appropriate plastic, and they also have the peculiarity that their lateral branches (10), (10 ') are asymmetric, that is one of them is substantially more long than the other, as seen especially in figure 3, in order to facilitate its assembly with the set constituted by the cover (3) and the partition (2) of the vault (1).

Se ha previsto también que dicha rama lateral (10), (10') de las grapas o pinzas presenten un acodamiento ortogonal interno (11) que, como también se observa en la figura 3, determina un apoyo lineal de la grapa sobre el tabique (3) de la bovedilla, lo que mejora el agarre de la grapa y consecuentemente la fijación de la tapa (3).It is also provided that said lateral branch (10), (10 ') of the clips or clamps have a bend internal orthogonal (11) which, as also seen in Figure 3, determines a linear support of the clip on the partition (3) of the vault, which improves the grip of the clip and consequently the cover fixing (3).
