Bidirectional displacement damping support

The invention belongs to the technical field of building supports, and particularly relates to a bidirectional displacement damping support. The support comprises a rotating body, symmetrical arc-shaped faces are arranged on the rotating body, and supports are arranged on the arc-shaped faces; the two ends, in the arc direction of the arc-shaped face, of the support exceed the rotating body, and the other two ends of the support are arranged in limiting parts connected with the rotating body. The support comprises a first support body and a second support body, the first support body and the second support body are arranged in an overlapped mode, the two ends of the second support body exceed the first support body and are arranged in the limiting part, the second support body is connectedwith the limiting part through an elastic damping element, and a gap is formed between the end of the limiting part and the second support body; the face, matched with the arc-shaped face of the rotating body, of the second
