<p>The invention is a new expendable form made of foamed material for concrete floors with a generically rectangular section and provided, in the upper part, with a V-shaped seat and, on the two sides with complementary projections and flutes; said expendable form conglomerates, in the foamed material, two or more reticulated triangular rods made of iron. Said expendable for can be provided with lightening holes. As an alternative to the V-shaped seat, the new expendable form can be provided with a generically rectangular section with some lateral chamfers so that a V-shaped notch can be obtained positioning two expendable forms side by side. When the new expendable forms are positioned directly on the lateral abutments of the floor they immediately made up the ribs on which the falsework of the beams is inserted. <IMAGE></p> |
