Further, since the rail set 10 is laid by digging down the fire-resistant and heat-insulating material 9 laid on the fire-resistant and heat-insulating material 8, as in the related art,
There is no need to provide a plate material around the rail set 10 to compensate for the protrusion of the rail set 10, and it is possible to contribute to a reduction in manufacturing cost because the plate material is unnecessary. Furthermore, since the rail set 10 is laid in such a manner that the fire and heat insulating material 9 laid on the fire and heat insulating material 8 is dug down, the thickness of the entire intermediate floor 30 can be reduced, and It is possible to increase the space in the upper direction of the fixed shelf or the space in the vertical direction of the movable shelf located in the upper layer.

In the above-described embodiment, three refractories are used.
Although the heat insulating materials 7, 8, and 9 are used, the thickness is not limited to this as long as the thickness of the fireproof and heat insulating material on the intermediate floor is maintained at a predetermined value. For example, two refractory and heat insulating materials may be used, or only one refractory and heat insulating material may be used. However, if three or less fireproof / insulation materials are used, that is, if two or one fireproof / heat insulation materials are used, the fireproof / heat insulation materials cannot be used as they are in the form of a plate. It is necessary to carry out a digging process in advance in consideration of a portion to which 10 is attached.

According to the present invention, a refractory heat insulating material is laid on the intermediate floor with a predetermined thickness, the rail is dug down by the refractory heat insulating material, and another refractory heat insulating material is provided between the beam and the rail. Is added to ensure the thickness of the refractory heat insulating material, so that a sufficient refractory and heat insulating effect can be obtained. In addition, since the rails are laid by digging fire-resistant heat insulating materials, the thickness of the intermediate floor can be reduced, and thus the rails are positioned vertically while obtaining a sufficient fire resistance and heat insulation effect as described above. The space in the vertical direction between the movable shelf and the fixed shelf can be expanded. Further, since the rails are laid by digging the fire-resistant heat insulating material, it is not necessary to provide another member around the rails to compensate for the protrusion of the rails, so that the manufacturing cost can be reduced accordingly.
