Descripción de la presente invenciónDescription of the present invention

La chapa metálica con perfil nervado objeto de la presente invención, ofrece al proyectista y al constructor un elemento básico para su aplicación inmediata en la realización de los antes mencionados forjados colaborantes, elementos mixtos de chapa de acero-hormigón, ya que posee una serie de ventajas, a causa de su particular diseño, de especial importancia en su utilización práctica.The metal sheet with ribbed profile object of The present invention offers the designer and the builder a basic element for immediate application in the realization of the aforementioned collaborating floors, mixed elements of steel-concrete sheet, since it has a series of advantages, because of its particular design, of special importance in its practical use.

Las chapas metálicas que se utilizan para formar los forjados colaborantes, han de ser necesariamente perfiladas previamente para dotarlas de unas nervaduras, con la finalidad de dar a la propia chapa una resistencia mecánica suficiente para someterse a sí misma y sostener el peso del hormigón y de la armadura metálica que sobre ella se depositará, sin deformarse una vez entre todo el forjado en carga.The metal sheets that are used to form the collaborating floors must necessarily be profiled previously to provide them with ribs, in order to give the sheet itself a sufficient mechanical strength to submit to itself and sustain the weight of the concrete and the metal armor that will be deposited on it, without deforming a time between all the forged load.

La chapa metálica con perfil curvado objeto de la presente invención, presenta como característica esencial, el estar dotado a lo largo de sus paredes no horizontales, de unos relieves obtenidos por embutición, cuya finalidad básica es dar a estas paredes una superior resistencia a la deformación, tanto por pandeo como por la presión lateral que ejercerá la masa de hormigón contra las mencionadas paredes no horizontales o caras laterales de la chapa, en el momento de entrar en carga.The sheet metal with curved profile object of The present invention, presents as an essential feature, the be endowed along its non-horizontal walls, about reliefs obtained by drawing, whose basic purpose is to give these walls a superior resistance to deformation, both by buckling as per the lateral pressure that the concrete mass will exert against said non-horizontal walls or side faces of the sheet, at the time of loading.

Estas embuticiones o relieves transversales, perpendiculares a la nervadura, presentan en cada extremo, sendas prolongaciones longitudinales, todas ellas de sección trapezoidal, y acabadas en cantos planos achaflanados, componiendo un diseño en forma de H con sus líneas verticales paralelas a los pliegues de la chapa, disponiéndose estas embuticiones a lo largo de las caras laterales al tresbolillo y con la embutición en el sentido hacia la zona donde se vertirá el hormigón.These embossments or transverse reliefs, perpendicular to the rib, present at each end, paths longitudinal extensions, all of them with trapezoidal section, and finished in flat chamfered edges, composing a design in H-shape with its vertical lines parallel to the folds of the sheet, arranging these embuticiones along the faces lateral to the tresbolillo and with the drawing in the direction towards the area where concrete will be poured.

El diseño particular de estos relieves en H obtenidos por embutición permite crear cuatro pares de puntos reforzados, de mayor rigidez, a causa del pliegue y deformación de las teóricas líneas resistentes del propio material de la chapa metálica, de forma que en estos puntos reforzados, estas líneas resistentes están mucho más unidas, con lo que se obtendrá una mayor resistencia al pandeo de los pliegues o caras laterales inclinadas, evitando cualquier deformación que pudiera provocar la separación del hormigón y de la chapa.The particular design of these reliefs in H obtained by drawing allows to create four pairs of points reinforced, more rigid, because of the crease and deformation of the theoretical resistant lines of the sheet material itself metallic, so that in these reinforced points, these lines resistant are much more united, so you will get a greater buckling resistance of the folds or side faces inclined, avoiding any deformation that could cause separation of concrete and sheet.

Estos relieves ofrecen, además, ofrecer una serie de rugosidades sobre las que la masa de hormigón tendrá un mayor agarre y, en consecuencia, garantizará la total consistencia del conjunto de chapa, hormigón y armadura, preparado para constituir el forjado colaborante.These reliefs also offer a series of roughnesses on which the concrete mass will have a greater grip and, consequently, will ensure total consistency of the set of sheet, concrete and reinforcement, prepared for constitute the collaborative floor.

Asimismo, el especial diseño de la chapa permitirá prescindir de las varillas de flexión de la armadura, debiendo colocarse solamente las varillas de retracción, con el consiguiente ahorro de material. Estas varillas de flexión son la que, teóricamente, quedarían ubicadas en la zona delimitada por cada uno de los valles de la chapa.Also, the special design of the sheet allow you to dispense with the reinforcement rods of the armor, only the retraction rods should be placed, with the consequent saving of material. These flex rods are the which, theoretically, would be located in the area defined by each one of the valleys of the sheet.
