In this manner, as shown in FIG. 1, the corner of the fixed shelf 2 is brought into contact with the pipe support 1,
A shelf in which the fixed shelves 2 are vertically arranged in parallel is completed. In addition, this shelf can be used by appropriately dividing an intermediate portion between the upper and lower shelves 2 and 2 with a partition shelf 3. This is achieved by fixing the partitioning shelves 9 in the intermediate notches 11c formed intermittently in the middle of the pipe support 1 and holding the partitioning shelves 3 in the partitioning shelves 9. Done. FIG. 7 is an exploded perspective view showing a state where the partition shelf plate 3 is attached to the intermediate notch groove 11c of the pipe support 1, and FIGS. 8 and 9 are a longitudinal sectional view and a transverse sectional view showing an assembled state. . As shown in FIG. 7, the partitioning shelf plate attachment 9 is formed by integrally forming a plate-shaped attachment piece 92 at the center of an L-shaped holding piece 91. Each of the plate pieces 94 and 94 of the holding piece 91 are connected to each other at an angle of 90 degrees, and the mounting piece 92 is provided on a bisector of the angle between the two pieces 94 of the holding piece 91. ing.

Each of the plate pieces 94 of the holding piece 91 is formed in a substantially rectangular plate shape, and the lower end thereof is formed to be slightly inclined upward toward the tip end. The attachment piece 92 is formed in a rectangular plate shape, but a portion connected to the holding piece 91 is formed slightly thick. A substantially U-shaped locking groove 99 is formed at the base end of the mounting piece 92 so as to open to the lower end. In addition, the width dimension of the locking groove 99 is the pipe support 1
Is formed slightly larger than the thickness of the peripheral side wall. The mounting piece 92 has a width dimension slightly smaller than the width of the cutout groove of the pipe support 1 and a height dimension shorter than the length of the cutout groove 11c of the pipe support 1. Since the partitioning shelf mounting fixture 9 is configured as described above, the mounting piece 92 is inserted into the middle notch groove 11c of the pipe support 1 and then pushed downward with respect to the pipe support 1, as shown in FIG. The lower end of the cutout groove 11c is engaged with the locking groove 99 to fix the mounting piece 92 to the pipe support 1. In this state, the tip of the mounting piece 92 is
