Description

Barra para armaduras de hormigón.Concrete reinforcement bar.

Objeto de la invenciónObject of the invention

La presente invención se refiere a una barra del tipo de las utilizadas como medio de armado para el hormigón, como por ejemplo las utilizadas en pilares, vigas, forjados, etc.The present invention relates to a bar of the type of used as a means of assembly for concrete, such as those used in pillars, beams, floors, etc.

El objeto de la invención es conseguir una barra que, manteniendo todas las prestaciones de una barra de acero convencional, de las utilizadas en el ámbito citado, presente una serie de ventajas adicionales que irán resultando palpables a lo largo de la presente descripción.The object of the invention is to achieve a bar that, maintaining all the benefits of a steel bar conventional, of those used in the aforementioned field, present a series of additional advantages that will be palpable at throughout this description.

La invención se sitúa pues en el ámbito de la industria de la construcción.The invention thus falls within the scope of the industry of the building.

Antecedentes de la invenciónBackground of the invention

Como es sabido, el hormigón es un material de construcción capaz de soportar grandes esfuerzos a compresión, pero cuya resistencia está mucho más limitada frente a los esfuerzos de flexión. Por esta razón raras veces el hormigón se utiliza de forma aislada, procediéndose habitualmente al ``armado'' del mismo mediante varillas, barras o redondos metálicos, concretamente de acero, que suplen las deficiencias del hormigón y que quedan debidamente embebidas en el seno de este último.As is known, concrete is a building material capable of withstanding great compressive stresses, but whose resistance It is much more limited in the face of bending efforts. For this reason rarely concrete is used in isolation, proceeding to the `` armed '' of the same by rods, rods or round metal, specifically steel, which they supplement the deficiencies of concrete and that they remain properly embedded within the latter.

Estas barras presentan un diámetro variable, en función de los esfuerzos a soportar en el contexto de la estructura de la que forman parte, y presentan normalmente una superficie coarrugada para mejorar la adherencia del hormigón a las mismas.These bars have a variable diameter, depending on the efforts to support in the context of the structure of which they are part, and usually have a coarrugated surface to improve the adhesion of concrete to them.

Las barras de acero, si bien cumplen de forma plenamente satisfactoria la función para la que han sido previstas en el seno del hormigón, presentan sin embargo una problemática que se centra fundamentalmente en dos aspectos, por un lado son considerablemente pesadas, lo que repercute negativamente en su transporte y manipulación, a lo que hay que añadir además la posibilidad de llegar a doblar ante esfuerzos transversales adecuados, y por otro lado se oxidan cuando están en contacto con ambientes húmedos, como por ejemplo durante largos periodos de almacenaje a la intemperie, problema que se ve notablemente agravado cuando, formando ya parte de la estructura, algún punto de dichas barras queda fuera de la cobertura del hormigón, pudiendo con el tiempo llegar, si las condiciones son favorables, a una total destrucción de la armadura metálica de una viga u otro elemento similar.Steel bars, although fully compliant satisfactory function for which they have been planned within of concrete, however, present a problem that focuses fundamentally in two aspects, on the one hand they are considerably heavy, which negatively impacts your transportation and manipulation, to which we must also add the possibility of get to bend before adequate transversal efforts, and on the other side oxidize when in contact with humid environments, such as for example during long periods of outdoor storage, problem that is noticeably aggravated when, being already part of the structure, some point of these bars is outside the concrete coverage, being able to eventually arrive, if conditions are favorable, to a total destruction of the armor metal of a beam or other similar element.

Descripción de la invenciónDescription of the invention

La barra para armaduras de hormigón que la invención propone, resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados.The concrete reinforcement bar that the invention proposes, solves the problem fully satisfactorily previously exposed, in the different aspects commented.

Para ello y de forma más concreta dicha barra se materializa en un cuerpo cilíndrico, de diámetro y longitud variables, obtenido a base de resina reforzada con fibra de vidrio.To do this and more specifically, this bar is materialized in a cylindrical body, of varying diameter and length, obtained at Fiberglass reinforced resin base.

Se consigue de esta manera una barra que con igual diámetro ofrece incluso más resistencia mecánica de una barra convencional de acero, que resulta mucho más ligera y elástica, que no dobla y que tampoco se oxida, constituyendo un objeto ``limpio'', que por lo demás puede ser ``atado'' de manera análoga a como se hace con la ferralla convencional, para la obtención de mallazos, armaduras para vigas o pilares, etc.In this way a bar with the same diameter is achieved offers even more mechanical resistance than a conventional bar  steel, which is much lighter and more elastic, that does not bend and that nor does it oxidize, constituting a `` clean '' object, which others can be `` tied '' analogously to how it is done with the conventional ferralla, to obtain meshes, reinforcements for beams or pillars, etc.

De acuerdo con otra de las características de la invención, se ha previsto que la superficie lateral de dicha barra esté provista de irregularidades, preferentemente de una ligera protuberancia de trayectoria helicoidal que se extiende a todo lo largo de la misma, determinante de un efecto machi-hembrado con el hormigón que mejora el agarre de este último con respecto a la barra. Esta protuberancia, levemente perceptible frente a la configuración general y cilíndrica de la barra, resulta no obstante sobradamente suficiente para determinar el grado de agarre necesario entre hormigón y barra.According to another feature of the invention, has provided that the lateral surface of said bar is provided of irregularities, preferably of a slight bulge of helical path that extends throughout it, determinant of a machi-female effect with the concrete that improves the grip of the latter with respect to the bar. Is bulge, slightly noticeable against the configuration general and cylindrical of the bar, it is nevertheless excessively enough to determine the degree of grip needed between concrete and bar.

La figura 1.- Muestra, según una vista en perspectiva, una barra para armaduras de hormigón realizada de acuerdo con la presente invención.Figure 1.- Shows, according to a perspective view, a bar for concrete reinforcements made in accordance with this invention.

La figura 2.- Muestra una pequeña porción de la barra de la figura anterior, a escala considerablemente mayor, para permitir visualizar los relieves superficiales de la barra que colaboran en la fijación del hormigón.Figure 2.- Shows a small portion of the bar of the previous figure, on a considerably larger scale, to allow visualize the surface reliefs of the bar that collaborate in concrete fixing.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la barra para armaduras de hormigón que la invención propone está constituida, como las clásicas barras de acero de cualquier armadura convencional, mediante un cuerpo (1) esencialmente cilíndrico, con cualquier longitud predeterminada acorde con las medidas comerciales de las barras o redondos de acero utilizados en la construcción, y con diámetro variable, de manera que, por ejemplo desde varillas de 6 mm de diámetro, se alcancen escalonadamente barras de hasta 30 mm y más, utilizables selectivamente en función de la resistencia mecánica del elemento de hormigón que en cada caso armar, pero con la especial particularidad de que dicho cuerpo esencialmente cilíndrico (1) consiste en una barra de resina, como por ejemplo una resina isoftálica, reforzada con fibra de vidrio.In view of the figures outlined, it can be seen as the concrete reinforcement bar that the invention proposes is constituted, like the classic steel bars of any reinforcement  conventional, by means of an essentially cylindrical body (1), with any predetermined length according to the commercial measures  of the rods or round steel used in construction, and with variable diameter, so that, for example from rods of 6 mm in diameter, bars up to 30 mm are reached step by step and more, selectively usable based on resistance mechanics of the concrete element that in each case assemble, but with the special feature that said body essentially cylindrical (1) consists of a resin bar, such as an isophthalic resin, reinforced with fiberglass.

La naturaleza de este material, como anteriormente se ha dicho, hace que para iguales dimensiones que una barra convencional de acero presente una mayor resistencia mecánica, una ligereza acusadamente mayor, y que además la barra no se doble ni se oxide, es decir que ofrece unas prestaciones considerablemente más altas que las de una barra convencional de acero.The nature of this material, as previously stated, makes for the same dimensions as a conventional bar of steel present a greater mechanical resistance, a lightness markedly greater, and also that the bar does not bend or rust, that is to say it offers considerably higher performance than those of a conventional steel bar.

Como complemento de la estructura descrita y como se desprende de la observación de la figura 2, el cuerpo (1) incorpora en su superficie un ligero relieve o protuberancia helicoidal (2), que a modo de un filete de rosca considerablemente aplanado y redondeado, que además puede ser simple o múltiple, le confiere un cierto aspecto ``salomónico'' y lo que es más importante, determina en el cuerpo (1) una superficie irregular, es decir ajena al cilindro perfecto, que asegura una óptima fijación del hormigón con respecto a la barra en cuestión, cuando ésta queda inmersa en el seno de aquel.As a complement to the structure described and as follows from the observation of figure 2, the body (1) incorporates in its surface a slight relief or helical protuberance (2), which at mode of a considerably flattened and rounded thread steak, which can also be simple or multiple, gives it a certain `` Solomonic '' aspect and most importantly, determines in the body (1) an irregular surface, that is foreign to the cylinder perfect, which ensures optimum concrete fixation with respect to the bar in question, when it is immersed within that.
