Abstract

The present invention relates to a lightweight bidirectional hollow core slab, and a doughnut-shaped hollow core body which may be advantageously used in the construction of a bidirectional hollow core slab. The doughnut-shaped hollow core body according to the present invention includes an outer skin entirely formed in the doughnut shape, wherein a hollow portion with a circular section is formed in the center of a solid body and corners are rounded with curved surfaces. The bidirectional hollow core slab according to the present invention is finished by stably positioning the doughnut-shaped hollow core body in the concrete slab in such a manner that the doughnut-shaped hollow core body is restrained and mounted in steel reinforcement cages or on the slab upper and lower steel reinforcements.
