Anti-seismic structure for modular building

The utility model relates to an anti-seismic structure for a modular building, which is mounted above an infrastructure platform and comprises a main body frame and a floor frame which are independently arranged, the main body frame is fixedly connected with an infrastructure platform through a shock absorber A arranged in the vertical direction; the bottom plate frame is arranged in the main body frame and is fixedly connected with the capital construction platform through a shock absorber B arranged in the horizontal direction; the shock-resistant floor frame is suitable for a relatively severe environment, a traditional integrated structure is avoided, the main body frame and the floor frame are relatively independently arranged, mutual influence is reduced, large-amplitude swing of articles placed on the floor frame indoors due to shaking of the main body frame is reduced, and meanwhile shock resistance can be effectively achieved due to the arrangement of the shock absorbers A, the shock absorbers B and
