ABSTRACT:
The upright annular concrete wall of a silo, swimming pool, or like structure of large diameter is poured in a slip form suspended from three columns for best stability of the slip form arrangement. A work platform is mounted on beams which radially connect the form with a coaxial, inner, annular frame. Carriers are interposed between the columns and the frame in such a manner that six approximately equally distributed circumferential portions of the frame are connected to the columns, so that the unsupported spans of the frame between connections to the carriers are only one half of what they would be if the frame were directly attached to the columns.
