PURPOSE: A form system for molding a concrete girder of a bridge is provided to manufacture a concrete girder of a trapezoid shape installed in a straight section and a curved section. CONSTITUTION: A form system for molding a concrete girder of a bridge comprises a base frame(2), a bottom base form(6), outer forms(10), inner forms(14), second side frames(16), a suspension device(20), a second side frame movement unit, a first side frame movement unit, a suspension device movement unit, and a base plate(50). The bottom base form is installed on the base frame. The outer forms are installed in the inner sides of first side frames(8) to be respectively symmetrical. The second side frames support the inner forms. The suspension device hangs the second side frames on the top of the base frame. The first side frame movement unit moves the suspension device. The base plate molds a base surface of the concrete girder. |
