METHOD OF ERECTION OF SHELLS ON PNEUMATIC FALSEWORK Russian patent published in 1998 - IPC

FIELD: erection of vaulted and dome-shaped frameless and frame bodies of metal or plastic plate members and of monolithic or built-up- monolithic fine-mesh wire-fabric reinforced concrete and reinforced concrete, ship hulls inclusive. SUBSTANCE: foundations 1 and base 2 are produced, soft inflated falsework 3 is mounted on base 2, and two compact flexible plate constructions 4 or two flexible multi-link constructions of hinge-joined rigid blocks that are hinge-joined to foundations 1 are placed flatwise directed towards each other over falsework 3 in the structure outline on the inner side in overlap for slippage between each other and over the falsework; fixing of shells in the design position after inflation of falsework 3 is accomplished in different variants, for instance, by coupling devices 5 and 6 located on opposite joint edges of flexible constructions, or by wire or strip bindings or hoops 7 of a fixed length, by restraint of the lower part of the walls by additional stiffening ribs 8, rigid external or internal arches, by filling of gaps between the rigid blocks by adhesive or hardening compounds. EFFECT: facilitated procedure. 12 cl, 11 dwg
