Abstract
A prefabricated reinforced and vibrated concrete joist, in the form of a double T, characterized in that the base and side faces of the lower head are longer in section than those of the upper, with opposite inclinations the faces that join the body; said beam carries in each of the heads or T, longitudinally three equidistant metal rods, of variable diameter, the central ones being joined by a series of transverse braces, which at the ends are separated by a distance corresponding to half the distance of the centrals. The upper and lower rods are joined together by a wire or rod of smaller caliber. (Machine-translation by Google Translate, not legally binding)
