El funcionamiento de la viga de acero como una estructura compuesta es conocido para una persona experta en la técnica y, así, no necesita ser descrito aquí con más detiene. En este contexto, se hace referencia, por ejemplo, a las publicaciones finlandesas 85745 y 92089 mencionadas anteriormente.The operation of the steel beam as a Composite structure is known to a person skilled in the technique and, thus, does not need to be described here with more stops. In In this context, reference is made, for example, to publications Finnish 85745 and 92089 mentioned above.
Según la idea esencial de la invención, al menos una parte de alma 2, 3 se hace de una pieza de chapa formada por dos partes longitudinales 2a, 2b y 3a, 3b, respectivamente, de la viga. Las partes 2a, 2b y 3a, 3b, respectivamente, forman un ángulo la una con la otra. La parte de chapa que forma la parte de alma 2, 3 se sujeta a la placa de base 1 y a la parte superior 4 de manera que la parte inferior 2a y 3a, respectivamente, de la parte de alma 2, 3 esté formando un ángulo con la placa de base 1 y la parte 2b y 3b superior, respectivamente, sea sustancialmente perpendicular a la placa de base 1. La estructura anteriormente mencionada se muestra de manera particularmente clara en la Figura 1. Las aberturas 6, a través de las cuales se puede verter el hormigón al interior del espacio formado por la placa de base 1, las partes de alma 2, 3 y la parte superior horizontal 4, están dispuestas en esta realización en las partes superiores 2b, 3b de las partes de alma 2, 3.According to the essential idea of the invention, at least a part of soul 2, 3 is made of a piece of sheet formed by two longitudinal parts 2a, 2b and 3a, 3b, respectively, of the beam. Parts 2a, 2b and 3a, 3b, respectively, form an angle One with the other. The sheet metal part that forms the soul part 2, 3 is attached to the base plate 1 and the top 4 so that the lower part 2a and 3a, respectively, of the soul part 2, 3 is forming an angle with the base plate 1 and part 2b and 3b higher, respectively, is substantially perpendicular to the base plate 1. The structure mentioned above is shown particularly clearly in Figure 1. The openings 6, through which concrete can be poured into interior of the space formed by the base plate 1, the parts of soul 2, 3 and the top horizontal 4, are arranged in this embodiment in the upper parts 2b, 3b of the parts of soul 2, 3.
En la realización de las Figuras 1 y 2, ambas partes de alma 2, 3 se hacen de una parte de chapa, las partes 2a, 2b y 3a, 3b, respectivamente, las cuales están formando un ángulo cada una con las otras. Este tipo de solución, sin embargo, no es la única solución posible, y se puede también aplicar la invención de una manera ligeramente diferente.In the embodiment of Figures 1 and 2, both Soul parts 2, 3 are made of a sheet metal part, parts 2a, 2b and 3a, 3b, respectively, which are forming an angle each with the others. This type of solution, however, is not the only possible solution, and the invention can also be applied in a slightly different way.
Las Figuras 3 y 4 muestran una segunda realización de la invención. En las figuras 3 y 4 se usan los mismos números de referencia que en las Figuras 1 y 2 para elementos correspondientes.Figures 3 and 4 show a second embodiment of the invention. In figures 3 and 4 the same are used reference numbers than in Figures 1 and 2 for elements corresponding.
La realización de las Figuras 3 y 4 difiere de la realización mostrada en las Figuras 1 y 2 en que en la realización de las Figuras 3 y 4, solamente se hace de una pieza de chapa una parte de alma 2, cuyas partes 2a, 2b están formando un ángulo la una con la otra. En esta realización, la segunda parte de alma 3 se hace de una parte recta de chapa sin aberturas.The embodiment of Figures 3 and 4 differs from the embodiment shown in Figures 1 and 2 in that in the embodiment of Figures 3 and 4, only made of a piece of veneer a soul part 2, whose parts 2a, 2b are forming a Angle with each other. In this embodiment, the second part of Alma 3 is made of a straight part of sheet without openings.
La realización de las Figuras 3 y 4 es una viga asimétrica que es especialmente ventajosa en estructuras de borde. Aquí se denomina una viga adecuada para las estructuras de borde a una viga que forma el borde de una estructura, tal como un piano de un edificio, de manera tal que la parte de alma 3 exenta de aberturas forme la superficie de borde del plano.The embodiment of Figures 3 and 4 is a beam asymmetric which is especially advantageous in edge structures. Here it is called a suitable beam for edge structures to a beam that forms the edge of a structure, such as a piano of a building, so that the soul part 3 exempt from openings form the edge surface of the plane.
Al fabricar la viga de la invención, se ha encontrado ventajoso utilizar unos soportes laterales 7 y unos soportes centrales 8, que se muestran con líneas discontinuas en la Figura 3. Los soportes laterales 7 y los soportes centrales 8 pueden ser dispuestos en la placa de base 1 a intervalos regulares en la dirección longitudinal de la viga. Pueden ser sujetados por soldadura, por ejemplo. Los soportes laterales 7 se disponen para determinar la posición de las partes de alma equipadas con unas aberturas 6 con respecto a la placa de base 7 y las partes centrales 8, a su vez, se disponen para determinar la localización de la placa que forma la parte superior 4. Los soportes laterales 7 pueden tener forma de L, por ejemplo, como en la Figura 3. Los soportes laterales y los soportes centrales se pueden cortar, por ejemplo, de un material de chapa.When manufacturing the beam of the invention, found advantageous to use side supports 7 and ones central supports 8, which are shown with dashed lines in the Figure 3. The lateral supports 7 and the central supports 8 can be arranged on the base plate 1 at regular intervals in the longitudinal direction of the beam. They can be held by welding, for example. The lateral supports 7 are arranged to determine the position of the soul parts equipped with openings 6 with respect to the base plate 7 and the parts centrals 8, in turn, are arranged to determine the location of the plate that forms the upper part 4. The lateral supports 7 they can be L-shaped, for example, as in Figure 3. The Side brackets and center brackets can be cut, by example, of a sheet material.
La invención se puede aplicar también de tal manera que las partes de alma 2, 3 se cortan con una forma curvada según una conformación previa curva de la viga. En este tipo de solución, es especialmente ventajoso el uso de los soportes laterales y centrales, puesto que los soportes laterales y centrales soportan y guían las partes de alma y la parte superior horizontal de manera muy efectiva durante la etapa de fabricación, en la cual se curva la placa de base a la curvatura de acuerdo con las placas de alma. Cuando se curva la placa de base en la manera anteriormente descrita, la placa que forma la parte superior 4 también se conforma por medio de los soportes centrales a la curvatura correcta.The invention can also be applied in such a way. so that the soul parts 2, 3 are cut with a curved shape according to a previous conformation beam curve. In this kind of solution, the use of brackets is especially advantageous lateral and central, since the lateral and central supports support and guide the soul parts and the horizontal top very effectively during the manufacturing stage, in which the base plate is curved to the curvature according to the plates soul. When the base plate is curved in the way previously described, the plate that forms the upper part 4 it also conforms through the central supports to the correct curvature
La placa de base 1, las partes de alma 2, 3 y la parte superior 4 se pueden sujetar las unas con las otras preferiblemente por soldadura. En caso de necesidad, la viga se puede también equipar con pestañas de extremo que cierren las partes de extremo. Las partes de extremo se sujetan soldándolas a los extremos de la viga.The base plate 1, the soul parts 2, 3 and the top 4 can be held together preferably by welding. If necessary, the beam is it can also be equipped with end tabs that close the end parts. The end parts are fastened by welding them to the ends of the beam.
