  • Girder block lifting method and jack-up stage used therefor
    Patent number: 8177080
    Abstract: A girder block lifting method, which can solve a problem that steel beams are inclined or fallen inward by lifting a heavy material, and a jack-up stage used therefor are provided. The method includes a main beam which can be provided between steel beams being targets of connection with the girder to construct a rigid frame structure, a height adjustment means (gate-shaped base) mounted on a cross beam member being parallel to the main beam and connecting other steel frames for adjusting height to the main beam, a connection beam for alternately connecting the main beam and the height adjustment means (gate-shaped base), and an auxiliary beam for connecting the connection beams. On a frame stage formed by connecting these beams, a plurality of lifting jacks are provided and a lifting sling is hung from upper part of the steel beam to enable jack-up of the girder block.
