A gliding frame for the erection of a slanting hollow building component, especially for the leg of an offshore platform, involving opposite frame walls (30) which are held up by downwardly projecting arch stays (10, 11) on several support beams (10 - 13) which for variation of the building components cross dimension and aspect are movable and pivoting relative to a frame superstructure (17, 35, 36). For the retention of power relating to the building components' sloping, there are several between the superstructure (17, 35, 36) and upwardly slanted inclining exterior sections (37, 38) of a pre-cast element (28) of the components' operative oblique struts (39, 40).<IMAGE> |
