Only rotation is possible. Of course, when the contact member 136a is pulled out from the ratchet wheel 135 by pulling the stopper 136, rotation is possible in any direction.

As illustrated in FIGS. 2 and 14, the upper support part 140 extends to upper ends of the first vertical member 110a and the second vertical member 110b, respectively.

The upper support part 140 is composed of a support plate 141 and a rotation support rod 142 formed under the support plate 141.

The support plate 141 is bent in a '┎' shape in a direction opposite to the building opening S, that is, the interior direction of the building. The support plate 141 may be formed to extend in one body to the first vertical member 110a and the second vertical member 110b, or may be fixedly installed by welding or bolting. When the support plate 141 is formed in a shape in which the upper end position of the building opening S corresponds to the ceiling, the first vertical member 110a and the second vertical member 110b by the height adjusting unit 120 are formed. When height is adjusted, it is in close contact with the ceiling of the building.

The rotary support rod 142 extends downward from the lower portion of the support plate 141 to be fitted to the inner diameter portions of the tubular first support member 171 and the second support member 172. With this structure, even when the support plate 141 is in close contact with the building ceiling, the first support member 171 and the second support member 172 can be rotatably supported.

3, the penetrating pin hole 175 is formed in the lower portion of the first support member 171, the coupling hole 132 is formed in the rotating member 133, and the rotating member is formed. A pin (not shown) is inserted into the pin hole 175 and the coupling hole 132 in a state in which 133 is inserted into the lower portion of the first support member 171 so that the first support member 171 and the rotating member ( 133 may be integrally rotated.

Although it is possible to include the barrier film tensioning unit 130 in the lower portion of the second vertical member 110b similarly to the first vertical member 110a, it is economical to have a structure capable of pulling the blocking film 180 only on either side. Since it is advantageous in terms of phosphorus, it is preferable to have a lower support portion 160 at the lower portion of the second vertical member 110b.

2 and 10, the lower support bracket 161 is connected to the lower portion of the second vertical member 110b by welding or bolting, and the lower support bracket 161. It consists of an extension support member 163 extending upwards from the. The lower support bracket 161 is installed in the room direction. The second support member 172 is a hollow body and has a lower end inserted into the extension support member 163. Although the cross-sectional shape of the second support member 172 is illustrated in FIG. 3 in a circular manner, the cross-sectional shape of the second support member 172 is not limited thereto.

As shown in FIGS. 2 to 4, the first support member 171 is spaced from the top to the bottom and protrudes, and the upper locking member 173 extends downward in the longitudinal direction of the first support member 171. The lower locking member 174 is spaced upward from the lower end and protrudes and extends upward in the longitudinal direction of the first support member 171.

The departure preventing member 190, as shown in Figures 2, 15 and 16, forms a cross-sectional structure of the '' 'shape, the first vertical member (110a) and the second vertical member (110b). It is fixedly installed at the desired position of.

The detachment preventing member 190 surrounds the first vertical member 110a and the second vertical member 110b and the first vertical member 110a and the second based on the horizontal protection part 150. It is provided to both the upper and lower sides of the vertical member (110b) or is installed to be fixed through a screw 194 or the like at any one of the upper and lower sides. To this end, a through hole 192 is formed at a predetermined position of the separation preventing member 190. The first vertical member 110a and the second close contact with both side walls of the opening S to fix the separation preventing member 190 to the first vertical member 110a and the second vertical member 110b. Move to the vertical member (110b) side, it can be fixed to the fixing hole 112 of the first vertical member (110a) and the second vertical member (110b) by passing the screw 194, etc. through the fastening hole (192). (See arrow ⓑ direction in FIG. 16).
