FIELD: construction.SUBSTANCE: invention relates to maintenance tools. The assembly rig (1) comprises a top frame (4) of the assembly rig provisioned over the longitudinal external edge of the large-size structure, the lower frame (3) of the assembly rig provisioned under the longitudinal external edge of the large-size structure, the connecting frame (5) of the assembly rig which connects the top frame (4) of the assembly rig and the lower frame (3) of the assembly rig to each other, only three bearing fixtures (2) for supporting of the lower frame (3) of the assembly rig from below, the shelf (6) of the assembly rig located perpendicular to the direction along which the lower frame (3) of the assembly rig passes, and parallel to the platform surface. The bearing fixtures (2) are provisioned on three sections which are located respectively under two ends of the shelf (6) of the assembly rig and under the lower frame (3) of the assembly rig. Positions of placement of the bearing fixtures (2) on three sections form a triangle on the top view.EFFECT: invention is aimed at improvement of precision of assembly.5 cl, 8 dwg |
