These stringers are mounted in pairs and each of them is coupled to the upper end of a upright 3. Separators 2 are interposed between each pair of stringers at said upper end of the uprights, which have the same shape and size of the connected stringers.
La riostra inferior consta de cuatro o más largueros 4 de una sección transversal circular o cuadrada situados en el plano horizontal de la base. Se integran con los montantes 3 en la misma forma que en la riostra superior. Los largueros 4 de la riostra inferior están también unidos a pares acoplándose cada uno de ellos con el extremo inferior de los montantes 3.The lower brace consists of four or more beams 4 of a circular or square cross section located in the horizontal plane of the base. Integrate with uprights 3 in the same way as in the upper brace. The stringers 4 of the lower brace are also attached to pairs coupling each of them with the lower end of the uprights 3.
Según una característica peculiar de la invención, las fibras de refuerzo mezcladas con el hormigón del fondo dan al último una resistencia de tracción uniforme limitada con objeto de evitar daños o grietas en el fondo que pudieran causar problemas en la resistencia mecánica y/o la resistencia al fuego.According to a peculiar characteristic of the invention, the reinforcing fibers mixed with the concrete of the bottom give the last a limited uniform tensile strength in order to avoid damage or cracks in the bottom that could cause problems in mechanical strength and / or resistance to fire.
En la primera realización mostrada en la figura 1, el fondo está provisto de un pequeño encofrado superior que consta de paredes laterales de contención C a las que están fijadas barras de sección longitudinales 8 en forma de L soportadas por barras transversales 7 unidas a los montantes 3.In the first embodiment shown in the figure 1, the bottom is provided with a small upper formwork that It consists of retaining side walls C to which they are fixed L-shaped longitudinal section bars 8 supported by crossbars 7 attached to the uprights 3.
Además la invención proporciona varios hierros transversales 5 soldados a los largueros inferiores 4.In addition the invention provides several irons transverse 5 soldiers to the lower stringers 4.
En esta primera realización, los montantes 3 tienen sus extremos inferiores junto con los largueros inferiores 4 englobados en el fondo o base F de hormigón reforzado con fibras de plástico. Debería apreciarse que la forma particular del encofrado según la presente invención hace innecesaria la utilización de cualquier tornillo pasante que podría perjudicar la resistencia al fuego.In this first embodiment, the uprights 3 they have their lower ends along with the lower stringers 4 encompassed at the bottom or base F of fiber reinforced concrete of plastic. It should be appreciated that the particular form of the formwork according to the present invention makes unnecessary the use of any through bolt that could damage the Fire resistance.
