PURPOSE: A form structure used for a composite rahmen bridge construction and a construction method of the composite rahmen bridge using the same are provided to prevent generation of the level difference by deflection, and secure durability of the bridge by controlling a crack. CONSTITUTION: A construction method of a composite rahmen bridge using a form structure is as follows. A steel girder lower flange of a middle section hangs a composite girder on the upper part of an abutment(1). A center form is installed in the middle section where casing concrete is placed. An end form and a hinge form are installed in the end part of the composite girder where the casing concrete is not placed. Concrete is placed in a housing space covered by the center form, the end form, and the hinge form. The placed concrete in the form is cured, and then the form is removed. |
