vía carabiru + estersensehac:En SOLUCIONES ESPECIALES he encontrado esta descripción de un sistema para hacer hormigón perforado.. el resultado es precioso!

El proceso para la construcción de muros de hormigón perforado consiste en: definir el diseño de las perforaciones, en este caso los patrones se han dibujado partiendo de dos algoritmos que permiten controlar la posición, el tamaño, el ángulo de desviación y la posición relativa entre círculos. Una vez establecido el patrón deseado se recortan los huecos sobre las tablas de encofrado, que posteriormente se montan en paralelo dejando la separación del grueso del muro, y manualmente se disponen los tubos los huecos, completada esta fase se vierte el hormigón tipo autocompactante y armado con fibras de acero de 10mm x 0.1mm

In this project we investigated the architectural potential of perforations in a 1:1 building element. After several design studies and the manufacture of prototypes from polystyrene panels, two walls were realised in concrete. The individual holes could be controlled in terms of four parameters: their position, the angle of their deflection from the surface, their rotation about their centre, and their size. Their distribution on the wall could be designed through globally acting forces of attraction and repulsion; a dynamic system oriented the holes against one another until a state was reached in which there was no overlap. The deflection from the surface and the size of the holes, on the other hand, were controlled via the colour values of a digital image file. These algorithmic tools offered the students an intuitive route into design, and were used to complement the programming of their own logics of distribution and orientation.
