PLANE CURVED STEEL FORM FOR PRESTRESSED CONCRETE GIRDER IT'S POSSIBLE TO ADJUST AND THIS METHOD OF FABRICATION

摘要

PURPOSE: A manufacturing method of a prestressed concrete girder using a steel form for a prestressed concrete girder capable of controlling a plane curve is provided to cheaply manufacture a steel form for a prestressed concrete girder. CONSTITUTION: A manufacturing method of a prestressed concrete girder using a steel form for a prestressed concrete girder capable of controlling a plane curve is as follows. A steel plate or a hunch form is attached on the inner sides of steel web plates(12) of unit segment steel forms(10) using welding or bolts(16). One of U-steel, L-steel, and I-steel is vertically attached on the outer sides of the steel web plates using welding or the bolts. Upper and lower steel plate flanges are vertically attached on the upper and lower surfaces of the steel web plates using welding or the bolts.
