REINFORCEMENT DEVICE FOR LOAD-CARRYING STRUCTURES Russian patent published in 2015 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: reinforcement device for load-carrying structures includes a metal frame installed on the load-carrying structure and made of vertical angled elements connected to each other with transverse planks, and a hold-down device having a possibility of acting on the metal frame in its longitudinal direction. The metal frame is rigidly attached to thrust members; the hold-down device is formed with a supporting structure and at least two hydraulic jacks installed in the lower part of the reinforcement device and interacting with the upper part to the supporting structure installed so that it can be borne against transverse support planks of the metal frame and supported from the above jacks. The jacks are supported through distributing devices from lower thrust angles installed on a mortar layer; with that, the supporting structure of the hold-down device is made in the form of at least two steel thrust members symmetrically adjacent to the load-carrying structure. A steel thrust member includes a flange of a U-shaped cross-section, which is provided with a wall exceeding the flange height and with ribs located in a T-shaped manner on the flange, by means of one of which with the wall part projecting above the flange there formed is a mating slot for the transverse support plank of the metal frame. The wall is located in a gap between the load-carrying structure and the transverse support plank, and under the second rib there located is a jack transmitting the thrust force through the steel thrust member and the transverse support plank to the metal frame.

EFFECT: reduction of material consumption.
