BUILDING STRUCTURE REINFORCEMENT METHOD Russian patent published in 2006 - IPC E04G23/02 

FIELD: building, particularly to repair beams, walls, columns and poles.

SUBSTANCE: method involves installing reinforcing members on structure to be reinforced and connecting the members with fastening members; welding the fastening members to one reinforcing member; heating thereof and welding the heated members to opposite reinforcing member; terminating the heating operation. The fastening members may be installed between reinforcing member surfaces or laid on ends thereof. In the first case initial fastening member length is determined from the following equation: L=S_BH-α·(T-T_a), where S_BH is distance between inner reinforcing member surfaces, α is linear expansion factor of fastening member material, T is fastening member heating temperature, T_a is ambient temperature. In the second case fastening member length is defined as L≥S_o, where S_o is distance between outer surfaces of reinforcing members.

EFFECT: increased reliability of structure to be reinforced.
