The invention relates to the field of buildings, in particular to a novel finished anti-seismic supporting and hanging rack and a using method thereof. The novel finished anti-seismic supporting and hanging rack comprises an anchor part, an anti-seismic buffer, a hanging rod, a vertical steel channel, a movable connector I, a saddle-shaped pipe hanger, a hung piece, a movable connector II, a lateral steel channel, a fastener and a supported piece. The specific structure of the novel finished anti-seismic supporting and hanging rack is that the anchor part is anchored into a building foundation; the upper portion of the anti-seismic buffer is connected with the anchor part; the lower portion of the anti-seismic buffer is connected with the hanging rod; the vertical steel channel is fixed to the hanging rod through the fastener; the upper portion of the lateral steel channel is connected with the movable connector I; the lower portion of the lateral steel channel is connected with the movable connector II; the saddle-shaped pipe hanger is connected with the hanging rod; the hung piece is hung through the saddle-shaped pipe hanger; the lower end of the hanging rod is connected with the horizontal steel channel; and the supported piece is supported on the horizontal steel channel. The novel finished anti-seismic supporting and hanging rack is suitable for the building industry with the supporting and hanging requirements, meets the supporting and hanging requirements in the building industry, and is suitable for the anti-seismic field during supporting and hanging.
