PURPOSE:To smoothly perform a molding work by disposing plural suspension beam members on a bridge leg along the bridge length direction, fixing both ends of thereof, and hanging a form centering of a form device for molding a bridge with suspension beam members. CONSTITUTION:Plural suspension beam members 18 are disposed along the bridge length direction X in positions corresponding to the space area of poids parts of a bridge 12 to be molded on a bridge pier 10 through support shoes 16 in such a manner that the lower surface 18a thereof is positioned above the lower surface 12a of the bridge 12. Subsequently, the upper ends of chemical anchor rods 20 fixed on the bridge pier 10 are inserted in both ends of the suspension beam member 18 and fixed through take-up devices 22. Subsequently, the form device 32 for molding a bridge is hung through form centerings 30 by hanging rods 24 disposed on the suspension beam member 18. Further, concrete is placed on the form device 32 to mold the bridge 12 with the suspension beam member 18 embedded. |
