15 ANTECEDENTES DE LA INVENCiÓN 15 BACKGROUND OF THE INVENTION
La historia de la construcción del hormigón presenta obras de distinto carácter formal sin embargo la necesidad de moldes para dar forma al hormigón y la construcción de estos moldes con elementos rígidos limita las capacidades del hormigón por lo que finalmente su uso más generalizado es en la construcción de geometrías cartesianas. The history of the construction of concrete presents works of different formal character, however the need for molds to shape the concrete and the construction of these molds with rigid elements limits the capabilities of the concrete, so finally its most widespread use is in construction of Cartesian geometries.
20 La construcción de formas curvas y en apariencia flexible con elementos rígidos conlleva una gran dificultad, trabajo laborioso y elevados costes económicos y temporales. 20 The construction of curved and apparently flexible forms with rigid elements entails great difficulty, laborious work and high economic and temporary costs.
En el panorama arquitectónico existen gran variedad de formas en la construcción de In the architectural panorama there are a variety of ways in the construction of
25 hormigón a las que los sistemas de encofrado tradicional no consiguen dar una respuesta adecuada. 25 concrete to which traditional formwork systems fail to give an adequate response.
La utilización de encofrados tradicionales nos presenta el hormigón como un elemento rígido y cuadriculado, desaprovechan su potencial formal, flexibilidad, capacidad de adaptación y The use of traditional formwork presents us with concrete as a rigid and squared element, wasting its formal potential, flexibility, adaptability and
30 expresividad. Dado que el hormigón refleja las cualidades del material que se utiliza en su encofrado el uso de materiales flexibles permitirá, además de utilizar la cualidad resistente del hormigón, aprovechar su carácter moldeable y sacar máximo rendimiento a sus posibilidades creativas y de expresividad . 30 expressiveness Since the concrete reflects the qualities of the material that is used in its formwork, the use of flexible materials will allow, in addition to using the resistant quality of the concrete, to take advantage of its moldable character and maximize its creative and expressive possibilities.
35 La armadura del hormigón es otro de los elementos que limitan su libertad formal. La necesidad de armadura en el hormigón para alcanzar una resistencia suficiente a tracción dificulta la construcción de formas complejas. Esta dificultad tiene su origen de nuevo en que tradicionalmente se utilizan elementos de armado rígido, tradicionalmente de acero. 35 Concrete reinforcement is another element that limits its formal freedom. The need for reinforcement in concrete to achieve sufficient tensile strength makes the construction of complex shapes difficult. This difficulty has its origin again in that traditionally rigid steel elements are traditionally used.
Respecto al armado han aparecido nuevos tipo de refuerzos plásticos, a base de fibras de vidrio o de carbono, pero no resuelven el problema debido a la imposibilidad de posicionarlas en lugar adecuado que permita un comportamiento eficaz y de ese modo alcanzar los mismos niveles de resistencia a tracción que los hormigones que utilizan un armado rígido. Regarding the assembly, new types of plastic reinforcements have appeared, based on glass or carbon fibers, but they do not solve the problem due to the impossibility of positioning them in a suitable place that allows an effective behavior and thereby reach the same resistance levels tensile than concrete using rigid assembly.
