JP6975517B2 - Smoke exhaust protruding window - Google Patents

Description

The present invention relates to a smoke exhaust window for allowing indoor smoke to escape to the outside in the event of a fire or the like.

As a smoke exhaust window as a smoke exhaust facility, a smoke exhaust window with a damper has been conventionally known so that the window can be opened smoothly.

For example, Patent Document 1 discloses a smoke exhaust protruding window in which a damper 29 is attached between a vertical frame 13 of a frame 1 and a vertical frame 17 of a shoji screen 2.
In such a smoke exhaust window, the problem of the damper caused by the fire must also be solved.

Patent Document 2 describes the problem as follows.
That is, "If a stay damper 6 containing flame-retardant oil is installed in the space between the vertical frame 3a of the smoke exhaust window 1 and the attachment frame 4, the oil can be burned or scattered by heating. It is described that there is a possibility that flames, oil, etc. may enter the room through the gap between the door stop portion 4a and the vertical frame 3a of the shoji 3 (see paragraph 0006).

As a solution to this problem, the document states that "the stay damper 34 is stored in the space k1 partitioned by the partition wall 33, etc." The partition wall 33 is used to prevent it from scattering inward "(see paragraph 0020).

Further, "the first to fourth heated foaming materials 36, 37, 38, 39 are provided in the space k1 in order to protect the smoke exhaust window 14 from the explosion and scattering of oil in the stay damper 34." It is stated to that effect (see paragraphs 0021 and 0022).

However, if the pressure generated by the explosion of the gas or the like filled in the damper attached to the smoke exhaust protrusion window is large, the heated foaming material may be blown off by the pressure. Moreover, when the sash frame of the smoke exhaust window is deformed by the pressure, there is a possibility that the flame invades through the deformed gap and the flame penetrates indoors and outdoors.
