Anti-seismic reinforcing mechanism for building

The utility model relates to the technical field of earthquake resistance, and discloses an earthquake-resistant reinforcing mechanism for buildings, which comprises a plurality of upper side bearing plates, and upper bottom bearing plates are fixedly arranged on the lower sides of the end surfaces of the sides, far away from a connecting central column, of the upper side bearing plates. Upper fixing plates are movably arranged at the positions, close to the upper sides, of the end faces of the sides, away from the connecting center column, of the multiple upper side bearing plates. According to the utility model, the erecting cross beam and the constructional column are wrapped by various bearing plates and fixing plates, and are mounted in a clamping manner, punching fixation is not needed, the original structural concrete of the beam column is not damaged, and compared with bolt connection, the mechanism is firmer and not easy to fall off after being mounted; the beam column connecting position, prone to b
