The utility model relates to a storied warehouse for storing bulk grain, which comprises a warehouse bottom, a warehouse wall, interlayer warehouse bottom plates, a warehouse top plate, a warehouse beam, a warehouse column, vertical transporting equipment, multi-point discharging and conveying equipment, warehouse inlet distribution chutes and warehouse outlet chutes. The vertical transporting equipment is arranged at an end part of the storied-warehouse and used for vertically lifting grain and conveying the grain to the warehouse top; the multi-point discharging and conveying equipment is fixed at the warehouse top and connected with the warehouse inlet distribution chutes; the grain gets into the storied-warehouse by penetrating the warehouse inlet distribution chutes of all the interlayer warehouse bottom plates; the warehouse outlet chutes are arranged on the interlayer warehouse bottom plates and penetrate through the warehouse wall; a large proportion of grain can automatically flow out of the storied-warehouse; and the rest grain gets out the storied-warehouse through a grain elevator and a free-flow pipeline. Connecting beams are arranged on the warehouse wall. The transfer channel of the grain lateral pressure is clear, and the grain lateral pressure borne by the warehouse wall is firstly transferred to the connecting beams, then transferred to combined columns from the connecting beams, and then transferred downward from the combined columns. The grain horizontal load is distributed according to the distribution of the connecting beams, the original triangular grain lateral pressure mechanical model with the stress gradually increased from a grain loading line to the warehouse bottom is changed, a mechanical model with connecting beams bearing staggered trapezoidal grain lateral pressure is formed, and the maximum value of the grain lateral pressure is greatly reduced, therefore, the mechanical behavior of the warehouse wall is more reasonable.
