The seats (4) on the separate supports are separated from one another correspondingly to the required distance between the secured joists (1A,1B). The body (2) is connectable to a lifting appts. (5) for rasing the framework with the support joists attached for locating against the underside of a building component. Each support (3) comprises at least two long units (10), the longitudinal direction of which extends across that of the joists, and which are adjustable in relation to the body where the length across the longitudinal direction of the joists is greater than the body width in the same direction. In a second situation, the two long units are located at least partly side by side, so that the support length is less than that in the first situation. |
