Since the present invention is configured as described above, it is possible to eliminate the trouble of inserting the upper beam and the lower support beam of the rail and the first panel into the beam fitting hole in the axial direction of the beam fitting hole. It can be fitted easily from the opening surface, and when the beam is moved slightly in the axial direction of the opening and the small protrusion of the beam is placed in the groove drilled in the beam fitting hole, the fitted beam will be removed. It can be securely installed by inserting and tightening bolts into the beam fitting holes without fear of the beams coming out of the beam fitting holes. This eliminates the hassle of drilling holes in the beam and the beam fitting hole, aligning both holes, and tightening bolts, and allows for easy construction by drilling only the beam fitting hole and tightening bolts, etc.
This has the effect of making work simple and inexpensive in both manufacturing and construction.
