Abstract
The invention relates to a method for conducting anti-seismic reinforcement through later-arranged dark ring beams in a masonry panel and a reinforcement structure of the method, and belongs to the technical field of anti-seismic reinforcement. The method is the technology that drilling devices are erected on the outer side of an existing building, at the position where the ring beams are planned to be built, long-distance horizontal drilling is carried out in a panel, reinforcing steel bars are arranged in holes in a penetrated mode, then the holes are filled with polymer mortar to form dark ring beam limiting rod pieces similar to the ring beams, and therefore ductility of the panel of an existing building is reinforced. When earthquakes occur, crack developing of the panel is limited, and integrity of the panel is strengthened. Damage of the anti-seismic force to upper structures is reduced. According to the method and the reinforcement structure, the anti-seismic property of a masonry body can be greatly improved without entering a room, construction is simple, and the construction cost is low. The method and the reinforcement structure are wide in application scope and suitable for solid brick walls, solid hollow blocks, cavity brick walls and boulder strip masonry walls.
