A lightening formwork (1) for reinforced-concrete objects, which is adapted to be fixed to a metal framework (101) for reinforced-concrete objects and which comprises: at least a first (2) and a second cup-shaped body (3), separate and independent from one another, which are mutually coupled/ couplable along the perimeter edge so as to form a closed and substantially globoidal-shaped, rigid shell (4); and a protruding wedge member (5), which extends cantilevered from the rigid shell (4) and is adapted to wedge and get stuck between a pair of metal bars (102) of said metal framework (101) .
