Por razones de claridad, la configuración curvada de la chapa de alma se muestra exagerada. En la figura 3, se muestra el ajuste de las chapas de alma 2 sobre la chapa de base. Durante la etapa de corte se realizan también aberturas 6 en las chapas de alma 2, a través de las cuales puede alimentarse hormigón al interior de la vigueta.In the next stage, the soul plates 2 are placed on the side supports 4. According to the idea essential of the invention, the core plates 2 are cut with a curved configuration according to the prebearing of the joist. By reasons of clarity, the curved configuration of the core plate is Exaggerated sample. In figure 3, the adjustment of the 2 core plates on the base plate. During the cutting stage openings 6 are also made in the core plates 2, through which can feed concrete inside the joist.
En la etapa siguiente del método de la invención, se dirige una fuerza hacia la chapa de base que obliga a la chapa de base 1 a la curvatura determinada por las chapas de alma 2, con lo que los soportes laterales 4 determinan la posición de las chapas de alma 2 y, a causa de que los soportes centrales se mueven con la chapa de base a la posición según la curvatura de la chapas de alma, los soportes centrales 5 determinan la curvatura de la chapa superior 3. La fuerza anteriormente mencionada está indicada con flechas en la figura 4.In the next stage of the method of invention, a force is directed towards the base plate that forces the base plate 1 to the curvature determined by the core plates 2, whereby the lateral supports 4 determine the position of the soul plates 2 and, because the central supports are move with the base plate to the position according to the curvature of the core plates, the central supports 5 determine the curvature of the top plate 3. The force mentioned above is indicated with arrows in figure 4.
La chapa de base 1, las chapas de alma 2 y la chapa superior 3 son fijadas conjuntamente mediante soldadura para obtener la vigueta mostrada en la figura 5. La vigueta puede ser equipada también con chapas extremas para cerrar los extremos de la vigueta. Las chapas extremas no se muestran en las figuras 1 a 5. Las chapas extremas son fijadas a la vigueta mediante soldadura. Las chapas extremas se muestran a título de ejemplo en la figura 7 y están indicadas con el número de referencia 7.The base plate 1, the core plates 2 and the upper plate 3 are fixed together by welding to get the joist shown in figure 5. The joist can be also equipped with end plates to close the ends of the joist. The end plates are not shown in figures 1 to 5. The end plates are fixed to the joist by welding. The end plates are shown by way of example in Figure 7 and are indicated by reference number 7.
El método de la invención descrito en lo que antecede resulta particularmente ventajoso porque la fabricación de la vigueta es realizada sin plantillas costosas que eran usadas antes en la fabricación de viguetas.The method of the invention described in what above is particularly advantageous because the manufacture of the joist is made without costly insoles that were used before in the manufacture of joists.
El hormigonado de las viguetas obtenidas de la manera anteriormente mencionada en relación con diferentes estructuras es conocido por los versados en la técnica y, por tanto, no se describe con mayor detalle en esta memoria. Simplemente se hace referencia a la publicación finesa 85745 en la que se describe esto con más detalle.The concreting of the joists obtained from the way mentioned above in relation to different structures is known to those well versed in the art and therefore It is not described in greater detail in this report. Just be refers to the Finnish publication 85745 in which it is described This in more detail.
Los soportes laterales anteriormente mencionados 4 son formados de tal manera que comprenden una parte para ser fijada a la chapa de base y que tiene un primer extremo 4a dispuesto para determinar el emplazamiento del borde inferior de la chapa de alma y un segundo extremo 4b dispuesto para determinar el emplazamiento del borde superior de la chapa de alma. Los soportes laterales 4 pueden estar hechos en principio con cualquier configuración. Una solución particularmente ventajosa es aquélla en la que la parte que ha de ser fijada a la chapa de base tiene sustancialmente forma de L y los extremos libres 4a, 4b de sus ramas están dispuestos para formar los extremos que determinan el emplazamiento de los bordes de la chapa de alma 2. En este tipo de solución, la superficie externa de una rama está dispuesta para servir de superficie de fijación entre la parte y la chapa de base 1. En la figura 6 se muestra este tipo de aplicación. Los soportes laterales 4 pueden ser fijados a la chapa de base 1, por ejemplo, mediante soldadura.The aforementioned side supports 4 are formed in such a way that they comprise a part to be fixed to the base plate and having a first end 4a arranged to determine the location of the bottom edge of the sheet soul and a second end 4b arranged to determine the location of the upper edge of the core plate. The supports lateral 4 can be made in principle with any setting. A particularly advantageous solution is that in the part that has to be fixed to the base plate has substantially L-shaped and free ends 4a, 4b of its branches are arranged to form the ends that determine the location of the edges of the core plate 2. In this type of solution, the outer surface of a branch is arranged to serve as a fixing surface between the part and the base plate 1. Figure 6 shows this type of application. The supports lateral 4 can be fixed to the base plate 1, for example, by welding.
Los soportes laterales 4 pueden ser cortados de un material a manera de chapa, tal como chapa de acero. Por ejemplo, los soportes laterales en forma de L usados en la realización de las figura 6 se hacen de esta manera. Los soportes centrales 5 pueden obtenerse de la misma manera que los soportes laterales 4. La configuración de los soportes centrales 5 también puede variar; en la realización de la figura 6, los soportes centrales son piezas separadas sustancialmente rectangulares. Sin embargo, es posible hacer los soportes de tal manera que el soporte lateral y el soporte central estén constituidos por un mismo elemento, si esto se considera necesario.The lateral supports 4 can be cut from a sheet-like material, such as sheet steel. By For example, the L-shaped side brackets used in the Embodiments of Figure 6 are made in this way. The supports central 5 can be obtained in the same way as the supports lateral 4. The configuration of the central supports 5 also may vary; in the embodiment of figure 6, the brackets Centrals are substantially rectangular separate pieces. Without However, it is possible to make the supports in such a way that the support lateral and the central support are constituted by the same element, if this is considered necessary.
Los soportes laterales y/o los soportes centrales pueden hacerse también de un material a manera de barra, etc.The lateral supports and / or the supports centrals can also be made of a bar-like material, etc.
