Description
Procedimiento para la ejecución de forjados de hormigón armado aligerados, con acabado visto en su cara inferior. Objeto de la invenciónProcedure for the execution of lightened reinforced concrete slabs, with a finish seen on its underside. Object of the invention
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un procedimiento para la ejecución in situ de forjados aligerados, con acabado visto en su cara inferior, aportando varias ventajas, que se describirán en detalle más adelante, que suponen una destacable mejora en el estado actual de la técnica. The invention, as stated in the present specification, refers to a procedure for the in situ execution of lightened slabs, with a finish seen on its lower face, providing several advantages, which will be described in detail below, which entail a remarkable improvement in the current state of the art.
Más en particular, el objeto de la invención se centra en un mejorado procedimiento para ejecutar “in situ” una losa de hormigón armado con elementos aligerantes, de modo que permita el acabado visto en su cara inferior, evitando un elevado peso así como las excesivas cuantías de acero de este tipo de elementos estructurales. Campo de aplicación de la invenciónMore particularly, the object of the invention focuses on an improved method for executing "in situ" a reinforced concrete slab with lightening elements, so as to allow the finish seen on its lower face, avoiding a heavy weight as well as excessive amounts of steel of this type of structural elements. Field of application of the invention
El campo de aplicación de la presente invención se enmarca dentro del sector técnico de la construcción, particularmente centrado en el ámbito de la ejecución de forjados de hormigón con acabado visto en su cara inferior. Antecedentes de la invención The field of application of the present invention is part of the technical construction sector, particularly focused on the field of execution of concrete slabs with finish seen on its underside. Background of the invention
Como es sabido, existe la tendencia en las estructuras de hormigón armado, ya sea por el ahorro económico de proyectar una capa de yeso y/o simplemente por cuestión estética, de diseñar forjados dejando visto el hormigón por su cara inferior. As is known, there is a tendency in reinforced concrete structures, either for the economic savings of projecting a plaster layer and / or simply for aesthetic reasons, of designing slabs leaving the concrete seen from its underside.
Esta tendencia obliga a realizar el forjado de manera que se pueda hormigonar completamente dicha cara inferior, es decir con un cierto grosor, al menos de unos cinco centímetros, para conseguir un acabado visto del hormigón en el que no se vea la existencia de elementos aligerantes que hayan sido apoyados sobre el encofrado y, además, que suponga una protección suficiente contra incendios, ya que dichos elementos aligerantes suelen estar realizados con materiales fácilmente inflamables. This tendency forces the slab to be made so that said lower face can be concreted completely, that is to say with a certain thickness, at least about five centimeters, in order to achieve a finish seen from the concrete in which the existence of lightening elements is not seen that have been supported on the formwork and, in addition, that it supposes a sufficient protection against fires, since said lightening elements are usually made of easily flammable materials.
Para ello, las soluciones actualmente conocidas en el estado actual de la técnica son, o la realización in situ del forjado mediante losas macizas de hormigón armado, es decir, sin aligeramiento, o, si se desea conseguir un menor peso, emplear elementos prefabricados, como prelosas o placas alveolares, que permitan la incorporación de elementos aligerantes. For this, the solutions currently known in the current state of the art are, or the realization in situ of the slab by means of solid reinforced concrete slabs, that is, without lightening, or, if it is desired to achieve a lower weight, use prefabricated elements, as pre-slabs or alveolar plates, which allow the incorporation of lightening elements.
El objeto de la presente invención es, pues, presentar un procedimiento alternativo a los elementos prefabricados, que presentan el inconveniente de ser caros, y a las losas macizas de hormigón armado, ya que éstas, además de ser también caras, implican un mayor peso en la estructura. The object of the present invention is, therefore, to present an alternative procedure to the prefabricated elements, which have the disadvantage of being expensive, and to the solid reinforced concrete slabs, since these, in addition to being also expensive, imply a greater weight in the structure.
El procedimiento propuesto, pues, es un procedimiento que evita dichos inconvenientes y permite ejecutar in situ una losa de hormigón armado con el acabado visto en su cara inferior e incorporando elementos aligerantes, debiendo señalarse que, por parte del solicitante, se desconoce al existencia de ningún otro procedimiento o invención similar que presente semejantes características técnicas, estructurales y constitutivas. Explicación de la invenciónThe proposed procedure, therefore, is a procedure that avoids these inconveniences and allows to execute in situ a slab of reinforced concrete with the finish seen on its underside and incorporating lightening elements, it should be noted that, on the part of the applicant, the existence of No other similar procedure or invention has similar technical, structural and constitutive characteristics. Explanation of the invention.
Así, el procedimiento para la ejecución in situ de forjados aligerados, con acabado visto en su cara inferior, que la presente invención propone se configura como una destacable novedad dentro de su campo de aplicación, ya que, a tenor de su implementación y de forma taxativa, se alcanzan satisfactoriamente los objetivos anteriormente señalados como idóneos, estando sus detalles caracterizadores desarrollados a continuación y recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva. Thus, the procedure for the on-site execution of lightened floor slabs, with a finish seen on its lower face, which the present invention proposes is con fi gured as a remarkable novelty within its field of application, since, according to its implementation and shape However, the objectives previously indicated as suitable are satisfactorily achieved, their characterizing details being developed below and included in the final claims that accompany the present specification.
De manera concreta lo que la invención preconiza es un procedimiento para la ejecución in situ de forjados aligerados, con acabado visto en su cara inferior, cuyo resultado será una losa con elementos aligerantes pero que funciona como un elemento unidireccional, consiguiendo solventar la problemática de la sujeción de los elementos aligerantes, ya que, como se ha señalado en el párrafo anterior, éstos no pueden estar apoyados sobre el encofrado, pues deben permitir el hormigonado de, al menos, cinco centímetros en toda la cara inferior del forjado, y consiguiendo solventar, también, la problemática de protección contra el fuego. Specifically, what the invention advocates is a procedure for the in situ execution of lightened slabs, with a finish seen on its underside, whose result will be a slab with lightening elements but that functions as a unidirectional element, managing to solve the problem of clamping of the lightening elements, since, as indicated in the previous paragraph, they cannot be supported on the formwork, since they must allow the concreting of at least five centimeters on the entire underside of the floor, and being able to solve , also, the problem of protection against fire.
Para ello el procedimiento preconizado comprende los siguientes pasos: For this, the recommended procedure includes the following steps:
Primero. Se coloca sobre el encofrado, con los adecuados separadores, un mallazo inferior contra la retracción, el cual es similar al empleado en las capas de compresión de los forjados unidireccionales. Dicho mallazo dependerá del canto del forjado, siendo lo más habitual una malla de diámetro de 5 mm con separaciones 20X30. Por su parte los separadores serán del tipo que convenga dependiendo de las circunstancias de cada caso. First. It is placed on the formwork, with the appropriate separators, a lower mesh against retraction, which is similar to that used in the compression layers of the unidirectional slabs. Said mesh will depend on the slab edge, the most common being a 5 mm diameter mesh with 20X30 separations. For their part, the separators will be of the type that is appropriate depending on the circumstances of each case.
Segundo. Mediante celosías de barras de acero electrosoldadas, se plantean los distintos nervios que forman la sección del forjado: armadura inferior, estribos y armadura superior. Second. By means of lattices of electro-welded steel bars, the different ribs that form the slab section are raised: lower reinforcement, stirrups and upper reinforcement.
Tercero. Entre dichos nervios, se colocan los elementos aligerantes, consistentes cuerpos de poliestireno expandido, o material similar, de configuración cilíndrica o similar, que van a permitir, por su forma inferiormente curvada, la existencia de una capa inferior de hormigón en todo el forjado. Third. Between said ribs, the lightening elements are placed, consisting of expanded polystyrene bodies, or similar material, of cylindrical or similar configuration, which will allow, due to their inferiorly curved shape, the existence of a lower concrete layer throughout the slab.
Cuarto. Se coloca otro mallazo en la cara superior y la armadura de negativos. Este mallazo impide que el elemento aligerante, debido a su escaso peso, suba hasta la superficie durante el proceso de hormigonado, permitiendo el correcto hormigonado de una capa de compresión en la cara superior del forjado. Fourth. Another mesh is placed on the upper face and the negative armor. This mesh prevents the lightening element, due to its low weight, from rising to the surface during the concreting process, allowing the correct concreting of a compression layer on the upper face of the floor.
Quinto. Se procede al hormigonado de todo el conjunto en una única fase. Fifth. The entire assembly is concreted in a single phase.
Es importante destacar que el diámetro de los elementos aligerantes cilíndricos implica que el intereje de los nervios sea aproximadamente el canto de forjado y, por tanto, mucho menor que el de los forjados unidireccionales convencionales, con lo que, para las luces y cargas habituales, la armadura a momentos positivos será suficiente con la de las celosías. It is important to note that the diameter of the cylindrical lightening elements implies that the interlocking of the ribs is approximately the forging edge and, therefore, much smaller than that of conventional unidirectional slabs, which, for the usual lights and loads, the armor at positive moments will be sufficient with that of latticework.
Además, conviene mencionar que el ancho de los nervios y el espesor de la capa de compresión superior, así como de la capa inferior, serán el necesario para proporcionar la adecuada resistencia y estabilidad ante el fuego que se requiera en cada proyecto. Respecto la capa inferior, es importante destacar que deberá tener, al menos, 5 cmm de grosor, necesarios tanto para ofrecer una adecuada resistencia al fuego como para conseguir un espesor mínimo para que la losa quede vista y no se marque el mallazo, ya que si el espesor fuera menor, probablemente se vería marcado en algún punto. In addition, it should be mentioned that the width of the ribs and the thickness of the upper compression layer, as well as the lower layer, will be necessary to provide adequate fire resistance and stability that is required in each project. Regarding the lower layer, it is important to note that it must be at least 5 cmm thick, necessary both to offer adequate fire resistance and to achieve a minimum thickness so that the slab is visible and the mesh is not marked, since if the thickness were smaller, it would probably be marked at some point.
Se constata pues que, ventajosamente, aunque el elemento estructural resultante presenta un peso propio y cuantías de acero algo superiores a las de un forjado unidireccional, dichos valores son muy inferiores a los de una losa maciza. It is therefore found that, advantageously, although the resulting structural element has its own weight and amounts of steel somewhat higher than those of a unidirectional slab, these values are much lower than those of a solid slab.
Por otra parte, el precio resultante será también inferior al de una losa, así como también al de un elemento prefabricado. On the other hand, the resulting price will also be lower than that of a slab, as well as that of a prefabricated element.
Y, además, si bien su precio será más caro que el de un forjado unidireccional, habría que sumar al precio de este último el del enlucido de yeso. And, in addition, although its price will be more expensive than that of a unidirectional floor, the plaster plaster should be added to the price of the latter.
El descrito procedimiento para la ejecución in situ de forjados aligerados, con acabado visto en su cara inferior, representa, pues, una innovación de características desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. Descripción de los dibujosThe described procedure for the on-site execution of lightened slabs, with a finish seen on its underside, thus represents an innovation of unknown characteristics so far for the purpose to which it is intended, reasons that together with its practical utility, endow it with sufficient basis to obtain the privilege of exclusivity that is requested.
