Anti-seismic performance reinforcement and crack repair structure of masonry structure and construction method of same

A method of performing anti-seismic reinforcement and crack repair of a masonry structure with masonry bricks on an outside of a wall, the method comprising:

• removing a predetermined depth of a horizontal joint along an entire circumference of the masonry structure by selecting the horizontal joint at a predetermined height on an outer surface of the masonry structure;
• mounting deformed bars such that the deformed bars are in contact with the horizontal joint by forcibly fitting a press-in holder to a perforated hole in the masonry structure while the deformed bars are coupled to a horizontal holder of a cross joint after perforating a vertical joint by selecting the vertical joint being in contact with the horizontal joint at predetermined intervals along the horizontal joint;
• fixing a deformed bar fixture to the wall by driving the deformed bar fixture thereto after inserting and coupling the deformed bar fixture to the press-in holder of the cross joint;
• and
• tying the entire circumference of the masonry structure after surrounding the entire circumference with the deformed bars.
