PURPOSE:To achieve simplification by providing movable supporting girders on both sides of each main girder, putting a partial form on each supporting girder, moving the supporting girders and suspending a bottom frame of each main girder between a pier and an intermediate column by hand and crane. CONSTITUTION:Supporting girders 3 provided on both sides of each main girder, each of which carries a partial form 6 thereon, advance. A bottom frame 4 of the main girder is lifted from the ground and suspended between a pier 1 and an intermediate column 2, so that reinforcing bars for the main girder and PC steel are assembled in advance on the frame 4 before the partial form 6 is brought thereto. At this time, each of the supporting girder 3 is brought to an assembling position in the interval in the rear, where partial forms 6 and bottom frames 4 are assembled and reinforcing bar arrangement of an upper floor, concrete placement and curing are performed. And when the form 6 is placed on the frame 4 having been assembled, the frame 4 is lifted by means of the girders 3 on both sides to place it at an assembling position so that the frame 4 and the form 6 are assembled to form the whole form. |
