PROBLEM TO BE SOLVED: To provide an inner form device capable of constructing a main girder for an accurate concrete box girder bridge without using a separator, to provide a method for adequately moving the inner form device after placing the main girder of the concrete box girder bridge and to provide the inner form device and its moving method capable of constructing the main girder of the concrete box girder bridge with a high workability in the inner form device and its moving method to be used when constructing the main girder of the concrete box girder bridge by sequentially extending the main girder.;SOLUTION: This inner form device comprises a central structural body (5) installed at the inner hollow center portion of the concrete box girder bridge (C1) to be built, support members (7, 8) which permit to move the inner forms (14, 15) provided at both the sides of the central structural body (5) respectively located at the upper portion and the lower portion of the central structural body (5) in a direction (y) perpendicularly to the bridge axis and horizontally, fit-in members (9, 9, 10 and 13) arranged in one united body with the inner forms (14 and 15) fitted in the support members (7 and 8), and adjusting members (17 and 18) which can adjust the horizontal position in the direction (y) perpendicular to the bridge axis of the inner forms (14 and 15) provided between the inner forms (14 and 15) and the central structural body (5).;COPYRIGHT: (C)2002,JPO
