And a rising edge is provided at a rear portion of the fire prevention plate, and a hanging edge is provided at a front portion of the fire prevention plate. According to the invention of claim 3, the racks of the two automatic warehouses are arranged back to back, and the fire protection plates provided on both racks are positioned so as to face each other, and the fire protection plates are formed so as to straddle the rising edges of the both fire protection plates. 3. The device according to claim 1, wherein at least a gap closing cover opened downward is covered.

[0005]

According to the present invention, the following effects can be obtained by the above configuration. According to the first aspect of the present invention, since the rising edge is provided only at the rear part of the fire prevention plate, when the fire protection plate is transported from the factory to the construction site of the automatic warehouse in a state where the fire protection plate is stacked, the rising edge is shifted back and forth. By stacking the fire prevention plates in such a manner, the fire prevention plates can be stacked without generating a gap between the fire prevention plates, so that the transportation efficiency can be improved as compared with the related art. In addition, since the rising edge is provided at the rear of the fire prevention plate, when the article transfer device provided on the elevator of the stacker crane is a slide fork, the article is moved by the slide fork between the elevator and the article storage shelf. When giving and receiving, the rising edge does not become a hindrance. As a result, the height of the rising edge can be increased, and the strength of the fire prevention plate can be increased. According to the invention of claim 2, a rising edge is provided at a rear portion of the fire prevention plate, and a hanging edge is provided at a front portion of the fire prevention plate, so that the fire protection plate is superimposed on a construction site of an automatic warehouse from a factory. When transporting, fire protection plates can be stacked without gaps between fire protection plates by stacking fire protection plates so that rising edges and hanging edges are shifted back and forth. Can be improved. Further, since the rising edge is provided at the rear part of the fire protection plate and the hanging edge is provided at the front part of the fire protection plate, the strength of the fire protection plate can be higher than that of the first aspect of the invention. According to the invention of claim 3, it is possible to easily close the rear gap between the mutually facing fire protection plates with the gap closing cover.
