In the mounted state of the decorative frame 14, a step portion 14 a is formed between the lower end portion of the upper decorative frame 14 and the outer surface of the fixed frame constituting member 11 so that the thickness of the frame increases upward. It is formed.
The means for fixing the decorative frame 14 to the fixed frame constituent member 11 uses a fastener 15 (for example, a screw or a bolt) according to the illustrated example. It is also possible to use the fixing means. As another example, the decorative frame 14 can be a single long member extending in the longitudinal direction of the fixed frame constituting member 11.

Then, as shown in FIG. 6 (b), the smoke proof curtain 1 is inserted into the ceiling side support frame 50.
The ceiling-side support frame 50 is a member having a U-shaped cross-section with an opening at the bottom, and extends in the lateral width direction. Projections 51, 51 are formed on the lower end side in the ceiling side support frame 50 so as to protrude in the thickness direction of the smoke proof curtain 1 and face each other. The ceiling-side support frame 50 is fixed to the ceiling portion a via a bracket 52 and a fastening tool 53 (for example, a screw or a bolt).

Therefore, the smoke-proof hanging curtain 1 inserted into the ceiling-side support frame 50 is temporarily fixed so that the stepped portion 14a on the upper end side is locked to the projections 51 and 51 and does not fall easily. The
Then, as shown in FIG. 6C, a fastening device 16 (for example, a screw or a bolt) is inserted into the ceiling side support frame 50, and the fastening device 16 is made up of the decorative frame 14 and the fixed frame constituent member. The smoke proof curtain 1 is fixed so as not to be dropped by being inserted and screwed into 11.

The space S absorbs the vibration when the smoke proof banner 1 and the ceiling part a and the wall part b are shaken by an earthquake or the like, and the smoke proof banner 1 irradiates the smoke proof banner 1. Prevent damage to the supporting part.

Therefore, according to the smoke proof curtain 1 and the installation structure A of the smoke proof curtain 1 configured as described above, when the hanging curtain body 30 fixed to the fixed frame 10 is loosened, the movable frame 20 is moved to the movable frame. If the pulling means 40 pulls the fixed frame 10 in the direction of the outside of the frame, the hanging curtain main body 30 is also pulled together with the movable frame 20, so that wrinkles and slack of the hanging curtain main body 30 can be eliminated.
In addition, since the movable frame tensioning means 40 having a simple structure is arranged between the fixed frame 10 and the movable frame 20, even if a plurality of movable frame tensioning means 40 are provided, the increase in weight is relatively small. As a result, even if the smoke proof banner 1 falls, the impact can be reduced.
In addition, since a plurality of movable frame pulling means 40 are provided in the lateral width direction (see FIG. 2), the vertical tension of the hanging curtain body 30 can be finely adjusted in the lateral width direction. It is possible to prevent wrinkles and slack from occurring over the entire length of the pulling means 40 in the width direction.
In addition, since a plurality of movable frame pulling means 40 are provided on the end side in the width direction with an interval in the vertical direction, the tension in the width direction of the movable frame pulling means 40 can be finely adjusted also in the vertical direction. it can.

Next, another example of the installation structure of the smoke proof banner 1 will be described with reference to FIG.
Since the installation structure B of the smoke proof banner 1 shown in FIG. 9 is obtained by changing a part of the installation structure described above, the changed part will be mainly described in detail, and redundant description will be omitted.

  The support frame 81 is a member that extends over substantially the entire length of the fixed frame constituent member 12 in the upward direction, and has a concave portion 81a that fits into the concave shape of the fixed frame constituent member 12 on one end side in the lateral width direction. In addition, a recess 81b is fitted into the end of the vibration absorbing film 82 in a substantially C-shaped cross section. The support frame 81 is fixedly fixed to the fixed frame constituent member 12 by a fixing tool 81c (for example, a screw or a bolt) inserted from the outside into the recess 81b.

Further, the vibration absorbing film 82 is a flexible sheet material provided in a state where the smoke proof banner 1 extends in the vertical direction and is bent in the horizontal width direction. As this sheet material, for example, a sheet material made of the same material as the hanging curtain main body 30 may be used.
Further, fastening bars 82a and 82b extending in the vertical direction are connected to one end side and the other end side in the lateral width direction of the vibration absorbing film 82, respectively. One fastening bar 82a is fitted to the recess 81b in the fastening member 83 so as not to come out in the lateral width direction. Further, the other fastening bar 82b is fitted to a fastening member 83 described later so as not to come out in the lateral width direction.
