The invention provides an unloading building and relates to the field of buildings. The unloading building comprises a load-bearing framework and further comprises a connection device and a plurality of unloading plates rotationally connected to the load-bearing framework. The two unloading plates are connected through a connection device, and when the two unloading plates are connected, the unloading plates cover the load-bearing framework. The unloading plates are rotationally connected to a support through a rotary shaft, the unloading plates located on the two sides of the rotary shaft include the first unloading plate and the second unloading plate, the area of the first unloading plate is S1, the distance from the centroid of the first unloading plate to the rotary shaft is L1, the area of the second unloading plate is S2, the distance from the centroid of the second unloading plate to the rotary shaft is L2, and S1*L1 is larger than S2*L2. The unloading building is simple in structure and capable of achieving unloading.
