AUTOMATED METHOD TO ERECT STRUCTURE FRAME Russian patent published in 2013 - IPC E04G21/14 

FIELD: construction.

SUBSTANCE: method to erect a carcass building consists in the following. After erection of the foundation, tubular columns of the carcass are mounted as oval in the cross section, and are rigidly connected with the foundation by anchor bolts. Main beams of the carcass are mounted and connected with the columns. A left non-detachable formwork is suspended onto the carcass with a tower crane, a concrete pump station is mounted, as well as flexible pumpcrete pipes. Plastic fine-grained expansive concrete is injected at the pressure into tubular shells by the "bottom up" method, and columns are turned into tube confined concrete pillars. After concrete setting, main and auxiliary beams of the slab are mounted. With the help of the tower crane the formwork left in the slab is suspended to the main and auxiliary beams of the slab. The additional operating reinforcement of the slab is mounted, flexible pumpcrete pipes are installed, and by control of concrete supply from a panel, the slab is concreted, and concrete is compacted through vibration. The building frame is grown onto the floor, and cycles of erection of the fireproof building carcass are continued until complete erection of the carcass and monolithic slabs of the structure.

EFFECT: reduced labour intensity of assembly.
