construction industry. SUBSTANCE: proposed way can be used for reinforcement of supporting structures of beam type ( for instance, beams of coverings, floors, crane beams, etc ). Way of reinforcement of beam with pre-stressed strut frame includes connection of strut frame from beneath and its pre-stressing. Columns of reinforcing strut frame are attached to beam with rigid tie bars. Columns of temporary strut frame tied up with cross bar and fitted with locating arms and stoppers are entered into spaces of columns of strut frame. Its tie bar is anchored on rigid tie bar of reinforcing strut frame. Tightening clamps are put on rests of the latter and tightened. Then ends of rigid tie bars are joined to beam and temporary strut frame is taken down. EFFECT: simplified process of reinforcement of beams by prestressed strut frame, reduced labor input. 5 dwg
