EFFECTS OF THE INVENTION The method of transporting a shelf board and a belt-shaped single body for a shelf board of the present invention can be carried out as described above, and the shelf board of the present invention constitutes this shelf board. The ribs on the top plate of each belt-shaped unit increase the surface strength of the entire shelf, and even if the thickness of the component plate material of each belt-shaped unit is reduced to reduce weight and reduce costs, the shelf plate when loading and unloading cargo There is no sticky feeling on the surface, and a high-class feeling can be maintained. Moreover, the concave streak or groove formed on the surface of each strip-shaped simple substance by the rib functions as a slip stopper for the load depending on the property of the surface of the load to be handled, and the risk of the load slipping off from the shelf board. Less likely.

When the strip-shaped simple substance having the above-mentioned cross-sectional shape is conveyed or stored, the two strip-shaped simple substances are separated from one side plate portion of one strip-shaped simple substance and the lip of one side of the other strip-shaped simple substance. Generally, the inner sides of the parts are fitted face-to-face so as to be adjacent to each other, and in this case, according to the configuration of claim 2, the outer surface of the lip part of one strip-shaped single body is Since the lip portion can be brought into surface contact with the back surface of the top plate portion of the other strip-shaped single body without riding on the rib projecting to the back side of the top plate portion of the other strip-shaped single body, the outside of the lip portion of the strip-shaped single body The side surface is less likely to be scratched, and it becomes easy to handle the two strip-shaped single bodies by fitting them face-to-face as described above.

Further, when the two strip-shaped single bodies are handled by being fitted face-to-face with each other as described above, according to the configuration of claim 3, the outer surface of the lip portion of one strip-shaped single body is different from that of the other strip-shaped single body. Not only does it not ride on the rib protruding to the back side of the top plate part, but also the relative movement of both strip-shaped units in the width direction is caused by the inner side of the lip on one side of one strip-shaped unit and the rib of the strip-shaped unit. Since it can be prevented by positioning by sandwiching one side of the other strip-shaped unit between
It becomes easier to handle the two strip-shaped single bodies by fitting them face-to-face as described above.

Further, according to the structure of the fourth aspect, the cross-sectional efficiency of the strip-shaped simple substance can be determined so that the rising plate portion bent and connected from the inner side of the lip portion and the position facing the rising plate portion or in the vicinity thereof. It can be effectively increased with the ribs provided on the.

Further, according to the structure of claim 5, by installing and using the shelves so that the strip-shaped simple substance of at least one side formed of the thick plate is located on the loading / unloading side,
Since the strength of the strip-shaped unit on the loading / unloading side is increased while the overall weight and cost are reduced compared to the case where all strip-shaped units are made of thick plates, the strip-shaped unit on the side of the load is loaded. It is possible to reduce the risk of deformation even if it is subjected to a larger load (load) than other band-shaped single bodies accompanying with taking in and out.

According to the sixth aspect of the present invention, the member mounting holes provided in the side plate portion of the belt-shaped simple substance can be utilized for mounting various name plates and the like, and the member mounting holes are provided. It is possible to minimize the reduction in cross-sectional efficiency (strength reduction) of the strip-shaped simple substance.

The present invention also provides a method of transporting a strip-shaped single piece for a shelf plate as described in claim 7. Claim 7
