In operation, it is caught through the hook 83a to the support pipe 45B welded to connect the two guide rings 45 in the middle portion. The support pipes 45B are interconnected by a central pipe 45A.

The support pipe 45B should be welded to the inside of the guide ring 45 as can be seen in more detail in FIG. 3A in order not to interfere with the folding operation of the inner wall panel assembly P1.

There are three scaffolds 83 in total, and four corners of the scaffolds 83 are provided with hooks 83a that span the horizontal bars 81.

Next, the folding means for the inner wall panel 20B to fold and unfold the hinge to the axis may be used a variety of known means. However, considering the force of the electric lifting means 70, the lightest folding means possible.

First, FIGS. 1A and 2A are provided with folding means 60 in the form of a turnbuckle. The turnbuckle 60 connects two panels 20B positioned at corners thereof, and in turn goes to a spiral part 63, a middle part 65, and attached to the panel while going toward the panel with the central rotating body 61 in the center. The fixing plates 67 are arranged in a symmetrical form.

The fixing plate 67 and the intermediate part 65 are connected to the connecting pins 67a to allow the angle of the turnbuckle 60 to be changed as the panel is folded and unfolded, and the two spiral parts 63 are opposite to each other. A spiral is formed in the direction so that the entire length of the turnbuckle 60 becomes longer or shorter as the rotation body 61 rotates. Alternatively, the spiral grooves formed in the rotating body 61 may be formed in opposite directions to each other.

In addition, the folding means 160 illustrated in FIG. 2B uses a hydraulic cylinder 160. The illustrated hydraulic cylinder 160 has a first intermediate portion 163 connected to one end of the cylinder portion with respect to the cylinder portion 161, a first connecting arm 164, a second intermediate portion 165, and a second connection. The arm 166 and the coupling plate 167 attached to the panel 20B are arranged in a symmetrical form.

The first intermediate portion 163 is formed with a guide hole 163a for the first connection arm 164, one end of which is coupled to the other first intermediate portion.

Both ends of the second connection arm 166 are connected to each other by the coupling plate 67 and the second intermediate portion 165A and 165B and the coupling pins 166a and 166b, respectively. As the folding and unfolding, it is possible to change the connection angle of the hydraulic cylinder 160 and the panel.

When the cylinder portion 161 expands, the panel 20B positioned at the corner portion is folded, and conversely, when the cylinder portion contracts, the panel is unfolded.

As shown in FIG. 2B, when the cylinder 161 is contracted, the first intermediate portion 163 on the left side may have a first connection arm 164 connected to the second intermediate portion 165 on the left side. Since the shape is fixed through the nut 164b coupled to the end bolt portion 164a of the first, the first connecting arm 164 is contracted along the guide hole 163a of the first intermediary 163 during contraction. The intermediary portion 163 slides closer to each other, so that the left and right two coupling plates 167, and eventually the inner panel 20B of the corner portion, are pushed to expand the panel assembly P1.

On the contrary, as shown in (b) of FIG. 2B, when the cylinder 161 expands, the first intermediate portion 163 is far from each other, and the coupling plate 167 is close to each other. The force on the panel causes the panel assembly to be folded.
