Therefore, the front frame 2 and the front frame 3
The top plate 4 is fixed to the top plate 4, and the system rack 1 is assembled as shown in FIG.

That is, when assembling the system rack 1 on site, the top plate 4 is attached to the front frame 2 and back frame 3.
, the bottom plate 5, the side panels 6.7 and the two shelves 8 can be easily attached to the system rack 1 without using numerous fasteners.
can be assembled, eliminating the need for numerous fasteners such as screws, washers, bolts, nuts, etc. As a result,
When assembling the system rack 1 on site, fastening tools such as screwdrivers, wrenches, spanners, etc. for tightening fasteners are no longer required.

Therefore, the system rack 1 can be assembled without using a large number of fasteners, so the number of parts can be reduced and parts management can be simplified. Furthermore, the assembly and work time can be significantly reduced.

(Modification) In this embodiment, the frame of the present invention is used for the front frame and the back frame, but it may also be used for a pair of side frames.

In this example, cylindrical materials with a cross-sectional shape or fan-shaped cross-section were used as the horizontal and vertical members of the frame, but it is also possible to use cylindrical materials, round bars, square bars, etc. It's okay.

In this embodiment, the pair of frames were formed into a square shape consisting of two parallel horizontal members and two parallel vertical members. It may be a letter shape, a substantially E-shape, a substantially H-shape, or the like.

In this example, the plates of the present invention were used as a top plate, a bottom plate and two
Although it was used for two side panels, it may also be used for plates such as top plates, bottom plates, shelves, panels, etc. that are hung between a pair of frames on site.

In this example, an engaging pawl was used as the engaging part, but a groove,
It may be a hole or the like, or a retaining portion may be provided on the JfS side plate. The engaged portion may have any shape as long as it can be engaged with the engaging portion.
