The invention relates to an apparatus for the construction of monolithic of multi-level or pillar-framed buildings having suspended ceilings, said apparatus is provided with surface- and in given case working level-forming formwork shell surrounding the monolithic concrete form-space of the ceiling, formwork bearer supporting the formwork shell, furthermore actuating mechanisms, e.g. lifting units for lifting and lowering the formwork bearer, the actuating mechanism, e.g. lifting units are in force-transmitting connection directly or indirectly with a certain part, e.g. pillars of the temporary or permanent vertical load bearing structures of the building, load bearing elements, e.g. bear frame, connecting member, etc. are built in between the formwork bearer and the lifting units. The essence of the apparatus lies in that the units /7/ are interconnected preferably with storey-high intermediate members /8/ forming forced trajectory for the formwork bearer /3/, furthermore the intermediate members /8/ are provided with releasable hinged bearers /9/ fixed to the vertrical load bearing structure /1/ temporarily holding and temporarily releasing the intermediate members /8/ and allowing the inching movement of the lifting units /7/ .
An improved process for constructing a multiple-story, reinforced concrete building, in which a central core tower is first erected on a conventional foundation by moving concrete forms incrementally upwardly. A work platform is mounted for self-propelled movement along the top side of the core forms, to move men and equipment to selected locations on the core tower as it is being erected, thus simplifying the construction and substantially reducing costs. Afer the core tower has been erected, floor slabs and integral, underlying walls are constructed from the uppermost floor downwardly using slab/wall forms that can be moved repeatedly downwardly without requiring disassembly and reassembly for each story. The integral, underlying walls associated with each floor slab provide the support structure for each story, thus permitting the slab/wall forms to be lowered without the need for re-shoring.
