JPH10127799A - Smoke-preventive dangling wall device interlocking with smoke sensor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To secure the level of ceiling and eliminate the sense of uncomfort and unnaturalness on the design by accommodating a dangling wall within the ceiling surface using an electromagnetic force, disengaging the electromagnetic force with actuation of a smoke sensor, and allowing the wall to dangle by its own weight. SOLUTION: Using hinges 3, one side of a dangling wall 1 is fastened flush with a ceiling in the lower part of an underlay plate 7 for ceiling, and an iron piece 13 is installed on the opposite side. This iron piece 13 is attracted and held by an electromagnet 5 installed on the ceiling 8 side and accommodated in the ceiling 8. One of the edges, not diagonal, of a swing stopper 2 is fixed by a hinge 4, and the whole surface is folded and placed on the wall 1 within the ceiling plane. When the electromagnetic force of the electromagnet 5 is disengaged interlocking ly with smoke sensing of a smoke sensor 6, the wall 1 retained is released, and the wall 1 dangles by its own weight to perform smoke prevention. At the same time, the swing stopper 2 will dangle down to preclude the wall 1 from swinging caused by the smoke flow pressure. At normal times, the wall 1 constitutes a part of the ceiling 8, which exhibits a natural finishing on the design.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sway-preventing wall (1) for automatically dropping from a ceiling when smoke is generated to form a spill-preventing sloping wall and at the same time preventing the sloshing of the sloping wall due to smoke flow pressure. Regarding 2).

[0002]

2. Description of the Related Art Conventional hanging walls always protrude downward from the ceiling surface by a width of 500 mm due to the regulations of the Building Standards Law, and the ceiling height has been partially reduced by 500 mm. In order to avoid the view hindered by the hanging wall, the hanging wall is made of glass to compensate for the disadvantage of the visibility.

[0003]

Conventional smoke-proof hanging walls use transparent glass in order to avoid obstructing the view of the ceiling surface. The part where the glass wall hangs down at all times cannot secure a complete ceiling height, and is uncomfortable and unnatural in terms of design, and was invented for the purpose of resolving this drawback.

[0004]

In order to achieve the above object, the hanging wall (1) device of the present invention is normally housed in a ceiling (8) surface by electromagnetic force (8), and smoke detector (6). When the magnetic force is released by the operation of (1), the surface side not supported by the hanging wall hinge (3) hangs down by the own weight of the hanging wall (1) to form the hanging wall (1). The right-angled triangular plate supported in the ceiling by the hanging wall (1) device also hangs down at the same time, and serves as a steady rest (2) of the hanging wall (1).

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS When smoke is generated due to a fire or the like, the magnetic force of the electromagnet (5) linked via the lead wire (12) is released from the smoke detector (6) and the magnetic force is lost. The smokeproof hanging wall (1) is formed. Also, the right-angled triangular support plate supported by the hanging wall device hangs in a direction perpendicular to the rotation direction of the hanging wall device, and stops the movement of the hanging wall in the rotation direction, and at the same time forms a steady rest (2). This can stop the movement due to the stream pressure of the smoke.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In Fig. (1), one side of the hanging wall (1) is fixed with a hanging wall hinge (3) on the same surface as the ceiling (8) below the ceiling base plate (7), and an iron piece attached to the opposite side (13) is held by the electromagnet (5). In the steady rest (2), one side other than the oblique side is stopped by the steady rest hinge (4), and the entire surface is bent and mounted on the hanging wall (1) in the ceiling surface.

The hanging wall (1) is made of a thin non-combustible material such as thin metal or glass and has a width of at least 500 mm and a length that can be held on the ceiling surface by electromagnetic force. .

[0008] The length of the hanging wall (1) is determined by the length of a necessary section in the room, but is connected every length that can be held on the ceiling by electromagnetic force. In order to prevent smoke flow between hanging walls (1), a gap is not formed between the hanging walls (1). In addition, a stopper (11) is set on the wall to also serve as a steady rest between the wall and a gap between the wall and the wall to prevent smoke flow.

The steady rest (2) is a right-angled triangular plate and is made of the same material as the hanging wall (1), and is formed of the same material as the hanging wall hinge (3). Attach with The hanging wall (1) interlocked with the smoke detector hangs vertically and at the same time hangs down in a direction perpendicular to the rotation direction of the hanging wall (1), and the vertical surface is made up of the side and the hypotenuse that contact the hanging wall and contact the ceiling surface. The right-angled triangle becomes the steady rest (12) and stops the swing of the hanging wall (1) due to the smoke pressure.

【The invention's effect】

The present invention has the following effects because it is configured as described above. This eliminates the need for a sloppy design in which a hanging wall, which is useful only when smoke is generated by a fire, is always suspended from the ceiling. Since the present invention hangs down by the operation of the smoke detector (6), it always hangs down the wall (1).
There is no need to secure the ceiling height in a state where the ceiling is suspended, and the ceiling height can be secured to the minimum necessary.

Claims (2)

[Claims] A hanging wall (1) held on a ceiling (8) surface by an electromagnet (5) loses magnetic force due to the operation of a smoke detector (6) and hangs down due to its own weight to form a smokeproof hanging wall (1). Smoke-proof hanging wall device forming. 2. A steady rest (2) device in which a right-angled triangular plate held in a ceiling together with a smokeproof hanging wall (1) hangs down simultaneously with the hanging wall to form a support wall.
