The present invention relates to a bar structure for a hollow slab capable of installing an upper main bar, an upper distributing bar, a lower main bar, and a lower distributing bar in the site without welding and conveniently installing, in the site, a light weight structure which is located between a top bar and a bottom bar without welding. In the bar structure for a hollow slab according to the present invention, a lower distributing bar (31) and a lower main bar (33), which are supported by a spacer (SP), are installed in a mold (1) for a slab composed of multiple deck plates (10) in a lattice shape and are bound by a binding wire. A second bracket (20) which has an L-shape is mounted on a bolt (15) of a first bracket (14) for fixing a truss girder (12) to a deck plate (10). A lightweight structure (40) is supported on the lower distributing bar (31). The multiple lightweight structures (40) are arranged in parallel to the lower main bar (33) in the same direction. The upper distributing bar (35) and the upper main bar (37) are installed on the upper part of the lightweight structure (40) to have a lattice shape and are bound by a binding wire. The upper end of a vertical steel wire (29) which has a lower end bound to the second bracket (20) is bound to the upper main bar (37). |
