Pretensed concrete semiviguettes for realization of forged. The semiviguetas (2) present a small horizontal zone in the upper part for support of the bovedillas (1). The channel presenting the top of the semivigueta presents a perimeter (7) very superior to the useful width (9) of the forged nerve; the channel presents a decrecient width in vertical sense, so that it is composed as a hopper, which favores the compacting of the concrete (6) during the spill; the width decrease is achieved by different stages of tilting, being the last of them of different inclination, to introduce additional metal strings that collaborate in resisting the cutting efforts next to the supports.
