Subsequently, the corner joint members 1 are attached to both ends of the horizontal frame member 84 in the longitudinal direction, and the vertical frame members 83 are attached to the corner joint members 1, respectively. An intermediate frame member 87 is attached. As a result, there are two spaces between the intermediate frame member 87 connected to one horizontal frame member 84 and each of the vertical frame members 83 on both sides, and the remaining one space for constituting the side plate frame 82 is provided. An E-shaped frame is formed to which the transverse frame members 84 are not yet attached.

A panel 85 is inserted into each of the two spaces between the intermediate frame member 87 and each of the vertical frame members 83 on both sides from the open end/open end of the E-shaped frame. Specifically, one of the pair of opposing end portions 851 of the panel 85 is inserted into the groove portion 832 of the vertical frame member 83 (specifically, between the pair of walls 832a) to The other of the ends 851 is inserted into the groove 872 of the intermediate frame member 87 (specifically, between the pair of walls 872a). The panel 85 is inserted and slid from the open end/open end of the E-shaped frame so that the leading edge 852 fits into the groove 842 of the horizontal frame member 84 (specifically, between the pair of walls 842a). inserted into.

At this time, the horizontal frame member 84, the vertical frame member 83 and the intermediate frame member 87 are joined by the corner joining member 1 and the intermediate joining member 2 in a manner that they are exactly perpendicular to each other, resulting in an E-shaped configuration. The panel 85 can be smoothly inserted and slid into the groove 832 of the vertical frame member 83 and the groove 872 of the intermediate frame member 87 without distortion.

A notch 853 corresponding to the shape and size of the insertion locking portion 14 of the corner connecting member 1 is formed in the corner of the panel 85 on the vertical frame member 83 side in order to avoid interference with the insertion locking portion 14 of the corner coupling member 1 . are formed at the corners of the intermediate frame member 87 to avoid interference with the second and third insertion locking portions 23 and 24 of the intermediate portion connecting member 2. A notch 854 is formed corresponding to the shape and size of the stops 23,24.

A transverse frame member 84 to which two corner joint members 1 and one intermediate joint member 2 are attached is further provided. Specifically, the first insertion locking portion 21 of the intermediate coupling member 2 extends from the longitudinal end of the horizontal frame member 84 (open end/open end) to the groove portion 842 of the horizontal frame member 84 . (Specifically, between the pair of walls 842a) and attached to the central portion of the horizontal frame member 84 in the longitudinal direction. Also, the corner coupling members 1 are attached to each of the longitudinal ends of the horizontal frame member 84 .

The transverse frame members 84 described above are attached to the open/open ends of the E-shaped frame. Specifically, each of the two corner connecting members 1 of the horizontal frame member 84 is connected to the vertical frame member 83 , and the intermediate connecting member 2 is connected to the intermediate frame member 87 .

As described above, the upper side plate 8A is assembled using the plurality of frame members (reference numerals 83, 84, 87) and the panel (reference numeral 85), and using the corner joint member 1 and the middle portion joint member 2. As shown in FIG.

(Action and effect of coupling member)
