In the slat structure according to the sixth embodiment, the band plate member on which the component is worn is the slat 93. As described above, the shutter curtain 11 is formed by connecting a plurality of slats 21 and connecting a base board 23 (87) at the lowermost stage. In the present embodiment, one of the arbitrary slats 21 above the skirting board 23 (87) is a slat 93 for wearing a component, and constitutes the shutter curtain 11.
In the slat 93 for wearing the parts, the same flange portion 37 including the receiving portion 67 and the rising portion 65 is formed.
According to this slat structure, it is suitable for the case where a lock device 43 and other resin parts are provided on an arbitrary slat 21 in the middle in the vertical direction of the shutter curtain 11, without receiving and dropping the molten resin, The spread of fire from the outside to the inside due to the burning of the molten resin can be prevented.

  Therefore, according to the slat structure of the fire shutter according to the present embodiment, it becomes possible to prevent the spread of fire due to the resin parts such as the lock device 43 being melted by heat from the fire and flowing down to the lower frame 31, for example. .

  Note that the indoor side described in each of the above-described embodiments not only means the indoor side with respect to the outdoor side of a building such as a house, but also the side on which the spread of fire is desired when a fire occurs is called the indoor side. For example, when a fire occurs in a hallway in a building, when the present invention is applied to prevent the spread of fire into the room facing the hallway, the hallway side is the outdoor side and the room inside is the room. In other words, the present invention is effective to prevent the spread of fire not only in the outdoors and indoors but also in separated compartments.
