DEVICE FOR AMPLIFICATION OF BEARING STRUCTURES Russian patent published in 2016 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: invention can be used for reinforcement of bearing structures of columns, walls and brick columns. Device for bearing structures reinforcement includes metal holder in form of vertical elements of angle shape interconnected by transverse planks installed on bearing structure, spacer device formed by prefabricated crossbar interacting with cage, and two hydraulic jacks mounted in lower part of device and interacting with top crossbar. Crossbar is made of interconnected elements enclosing cage bottom part to act on lower ends of vertical elements of framework for transfer of pretension force. Crossbar comprises tightened by means of ties post angle section covering vertical elements of cage, and two support angles horizontally located on side of jacks, and connected to each other by bolted joints. One end of each support area is rigidly connected to post, and by other end is placed under top crossbeam support element, rigidly fixed on end of adjacent post to form hinged support joint. In posts base L-shaped crossbar support elements are fixed, made with possibility to interact with lower ends of vertical elements and transmit pretension force.

EFFECT: reduced material consumption of device.
