2. Description of the Related Art Conventionally, a three-dimensional warehouse has been used for three-dimensionally storing long materials such as round bars, square bars and tubes. This type of three-dimensional warehouse has a plurality of storage shelves vertically formed from a plurality of warehouse frames that are arranged upright in the front-rear direction and are formed by horizontally extending arms. It is a structure in which the materials are placed and stored on each storage shelf in a tiered manner.

The material is carried into or out of the storage rack by a stacker crane. These stacker cranes are orthogonal to the extending direction of the arms above and below the left and right crane bodies provided so as to run across the entire warehouse frame in a direction parallel to the above extending direction of the arms. A fork that is long in the direction of the arrow is provided so as to be able to move up and down along the left and right portions of the crane body, and a pair of hooks is configured to be movable on the fork.

The left and right ends of the material are held and held by hooks on the forks of the crane that move up and down between the open ends of the storage shelves, and the above-mentioned running operation of the stacker crane and the fork of the stacker crane are held. The material is carried in from the outside of the three-dimensional warehouse or the material on the storage rack is carried out of the three-dimensional warehouse by the lifting operation and the moving operation of the hook.

[0005]

When materials are loaded into the three-dimensional warehouse from the outside, the stacker-crane forks fall from above the warehouse frame into the gap between the open ends of the storage shelves. When the material of the desired storage rack is transferred and the material on the storage rack is carried out of the three-dimensional warehouse, the fork of the stacker crane moves in the gap between the open ends of the storage rack. It moves up and is transferred from above the warehouse frame to the outside of the three-dimensional warehouse. Therefore, the adjacent warehouse frames cannot be connected to each other in the traveling direction of the stacker crane, but are merely forested.

The warehouse frame is constantly loaded with the weight of the material placed on the storage shelves and is weak against the horizontal external force acting on the three-dimensional warehouse, that is, the external force caused by an earthquake.

The object of the present invention was proposed in view of the above problems in a conventional three-dimensional warehouse, and is devised so as to have excellent earthquake resistance and not to hinder the vertical movement of the forks of the crane. To provide a three-dimensional warehouse.
