Slab-form equipped for pre-fabricated reinforcing bar

A slab form having a prefabricated reinforcing bar is provided to omit the progress of the bar reinforcement work by processing a reinforcing bar in a reinforcement truss and coupling with a sheathing board, to secure structural stability of a form by using prefabricated lattice bars, and to omit the progress of the timbering installation work by applying to suspension construction placing on a wall form or hanging a reinforcement truss assembled slab form on an upper pre-constructed structure. A slab form having a prefabricated reinforcing bar comprises many anchorages(140) placed on the upper part of a sheathing board(110) in a lattice pattern and coupled with a lower chord(122) of a wide width lattice bar, a fixing bolt(150) provided with a male thread to couple with a washer nut and a bar-shaped smooth top portion(151) to insert a screw stopper of a narrow width lattice bar, a spacer(160) placed between the sheathing board and the anchorage and provided with a through hole to penetrate the fixing bolt to contribute to secure the covering thickness of the wide width lattice bar, and a washer nut(180) fixed to a screw stopper(141) of the anchorage and the bottom of the sheathing board and coupled with the fixing bolt penetrated the screw stopper. in addition, many hollow air bags are installed between an upper chord and a lower chord of the narrow width lattice bar to reduce the quantity of concrete used for manufacturing a slab.
