Description

[Detailed description of the invention]

[0001]

Industrial Applicability The present invention projects on the ceiling of a building below the ceiling surface so as to prevent the spread of smoke in the event of a fire and to prevent the development of a large fire. The present invention relates to a smoke-proof saucer wall mounting structure provided with a fire-resistant and heat-resistant plate in a state.

[0002]

2. Description of the Related Art Conventionally, when a smoke-proof sagging wall is mounted, a fire-resistant and heat-resistant material such as a glass material forming the smoke-proof sagging wall is provided in a groove formed between opposing walls or between adjacent walls. The upper edge of the plate was fitted, and the plate was fixed to the ceiling so that there was no gap between the upper edge of the plate and the groove in this state.

[0003]

[Problems to be Solved by the Invention] However, since the conventional smoke-proof saucer wall is fixed to the ceiling, there is no problem at normal times, but when carrying luggage with a relatively high height, There was a drawback that the luggage collided with the smoke-proof sauce wall and the smoke-proof sauce wall and the luggage were damaged.

In addition, when a smoke-proof sagging wall is damaged, it is left unrepaired without repair, and when a fire occurs, smoke flows from the damaged portion and the spread of smoke cannot be prevented.

The present invention has been made in view of such circumstances, and has as its object to prevent damage to a smoke-proof sagging wall caused by collision with another object.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a fireproof and heat-resistant plate provided on the ceiling of a building so as to protrude downward from the ceiling surface. In the mounting structure of the saucer wall, the upper end side of the plate is swingably mounted on the ceiling around the horizontal axis, and between the upper edge of the plate and the ceiling, the plate is allowed to swing. A fire-resistant and heat-resistant sealing material that blocks the passage of smoke is provided.

[0007]

According to the construction of the mounting structure of the smoke-proof saucer wall of the present invention, even if something such as luggage collides with the plate material, it is maintained in a state in which the passage of smoke is prevented by the fire-resistant and heat-resistant sealing material. While the plate material swings and escapes, the impact force of any of the other object and the plate material can be reduced.

[0008]

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overall schematic front perspective view showing a structure for mounting a smoke-proof sagging wall according to the present invention.
The wall protruding below the ceiling surface and facing
A fire-resistant and heat-resistant plate material 3 is provided in a state extending between the two to form a smoke-proof sagging wall A.

As shown in the partially cutaway enlarged front view of FIG. 2, the plate member 3 has aluminum vertical frames 6 attached to upper and lower aluminum frames 4, 5 at predetermined intervals in the longitudinal direction. Glass with wire mesh inside 4,5 and vertical frame 6 ...
Is fitted so as to have fire resistance and heat resistance.

As shown in the cross-sectional view of the main part of FIG. 3, a groove 8 for fitting the upper aluminum frame 4 is formed in the ceiling 1 over the entire length between the opposed walls 2 and 2. The mounting brackets 9 are mounted in the groove 8 at predetermined intervals in the longitudinal direction, and the upper aluminum frame 4 can swing around the horizontal axis P via the hinges 10 in each of the mounting brackets 9. Installed.

A groove 8 is filled with rock wool 11 as a fire-resistant and heat-resistant sealing material so as to cover the upper side of the upper aluminum frame 4 from the upper side and the periphery of the hinge 10, and swing the plate 3. Is configured to prevent the passage of smoke from one side to the other while sandwiching it.

With the above configuration, in the event of a fire or the like,
Smoke can be prevented from spreading early on one ceiling,
Moreover, when another object collides with the smoke-proof dripping wall A, it swings and the smoke-proof dripping wall A escapes, so that the impact force of both the other object and the smoke-proof dripping wall A can be reduced to prevent breakage. Has become.

In the above embodiment, the fire-resistant and heat-resistant plate member 3 is provided so as to extend between the opposing walls 2 and 2, and the smoke-proof dripping wall A is provided.
However, for example, the smoke-proof sagging wall A may be configured by providing the state over an adjacent wall, or by providing the same wall in a rectangular shape.
In such a case, at the corners, the edges of the adjacent plate members may be connected to each other by a fire-resistant and heat-resistant sheet or the like so as to allow the adjacent plate members to swing.

[0015]

As described above, according to the mounting structure of the smoke-proof saucer wall of the present invention, the impact of any object or plate caused by collision with another object such as luggage due to the swing of the plate. Therefore, it is possible to prevent damage to other objects and the smoke-proof sagging wall, and also to prevent a decrease in safety at the time of fire occurrence due to the damage to the smoke-proof sagging wall.
