In recent years, in order to increase the storage efficiency of the load W, the frame shelves 30 are becoming higher in number. The height of the frame shelf is 10
In the case of about m, each strut 31 had one strut having a length corresponding to its height. As the frame shelves 30 become higher in height, long pillars are required. However, if the length is too long, it is not possible to deal with one prop because of the limitation of the pillar manufacturing equipment such as the painting process, the carry-in space at the installation site of the frame shelf, or the transportation limit. . For example, in the frame shelf 30 having a height of about 15 m, the support column 31 configured by connecting the upper support column 38 and the lower support column 39 is used.
