Each shield plate 15 has sliders 16 on both sides, and the sliders 16 are provided in guide grooves 17 provided on the opposite surfaces of the left and right vertical frames 11, 12. Engaged. The guide groove 17 is provided in the lengthwise direction of the left and right vertical frames 11 and 12, and a plurality of guide grooves 17 are provided indoors and outdoors to guide the vertical movement of the plurality of shield plates 15.
Further, each shielding plate 15 has a contact piece 18 protruding in an inverted L shape toward the indoor side on the upper side, and a contact piece 19 protruding in an inverted T shape on both the indoor and outdoor sides on the lower side. . The contact piece 18 is capable of contacting the outdoor side upper surface of the contact piece 19 of the adjacent shield plate 15, and the indoor side upper surface of the contact piece 19 of the shield plate 15 is adjacent.
It can come into contact with the lower surface of the outdoor side of 19.

Therefore, if the shield plate 15 at the outermost position is lifted up to the position of the shield housing portion 14, the shield plate 15 is guided by the guide groove 17 and moves upward, and the upper surface of the contact piece 19 of the shield plate 15 on the indoor side. Touches the lower surface of the contact piece 19 of the adjacent shield plate 15 on the outdoor side and sequentially moves the adjacent shield plate 15 upward, and all the shield plates 15 are housed in the shield housing portion 14 in a stacked state in the indoor and outdoor directions. Will be done. Then, in this state, the lock release device 20 is engaged with the shield plate 15 at the outermost position to move the shield 8 to the shield housing portion 14.
It is designed to be supported and stored inside.

The unlocking device 20 is attached to the outdoor side of the shield housing portion 14 of the upper frame 9, and has a contact piece 19 of the shield plate 15 at the outermost position.
It is provided with a rod-shaped stopper 21 attached to the shield accommodating portion 14 so as to be able to move forward and backward at a corresponding position, and a shape memory alloy coil 22 having one end attached to the upper frame 9 and the other end attached to the stopper 21. The coil 22 always uses the stopper 21 as the shield housing portion 14
Of the shield plate 15 at the outdoor position.
The lower surface of the contact piece 19 is engaged and locked to maintain the housed state. In addition, the coil 22 has a shape memory so as to be in a contracted state when heated, and when the coil 22 is heated in the event of a fire, the coil 22 is deformed into a contracted state and is a stopper.
21 is supposed to be relocated.

Therefore, in the event of a fire, the stopper 21 releases the lock of the shield plate 15 at the outermost position, and each shield plate 15 falls due to its own weight. In this case, the shield plate located on the outdoor side
