Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fire shutoff device for a parking tower.

In tower parking, where cars are placed on each mounting part of a lift installed in the tower main body, and a large number of cars are stored in a vertical space inside the tower main body,
If the tower main body is not provided with a ceiling wall and the upper part of the tower main body is opened, construction costs can be reduced. However, with this structure,
If a fire breaks out inside the tower body, the fire will erupt outside from the open upper end of the tower body.
The problem arises that this is not desirable in terms of disaster prevention.

Therefore, with this invention, when a fire breaks out inside the tower body with the top open, when the fire alarm switch is pressed,
The object of the present invention is to provide a fire shutoff device for a parking tower in which an open part of the upper part of the tower main body is automatically shielded with a noncombustible sheet to prevent fire from spreading to the outside.

The configuration of the present invention will be described in detail below based on embodiments shown in the accompanying drawings.

2 is the main body of the tower parking tower, and its upper end is open. A well-known lift 4 equipped with a large number of car mounting parts is installed in a space 2a extending in the vertical direction of the tower body 2. The upper end of the tower body 2 is open, and sheet winding shafts 6 and 8 are rotatably mounted approximately in the center of the upper end.
Noncombustible sheets 10 and 12 are wound around.
Rattle wheels 14 and 16 are fixed to the winding shafts 6 and 8. A member 17 that supports the winding shafts 6 and 8
The bracket fixed to the bracket has claw members 18, 19.
is rotatably supported, and one of the pawl members 18 and 19 is engaged with an operating shaft 21a of a solenoid 21 fixed to the member 17. the claw member 18,
19 meshes with the ratchet wheels 14, 16 as shown in FIG. 3, and prevents the ratchet wheels 14, 16 from rotating. The claw members 18, 19 and the solenoid 21
constitutes a locking mechanism that locks the rotation of the winding shafts 6 and 8. Flexible wire ropes 20, 22, 24, 2 are attached to one end of each of the noncombustible sheets 10, 12.
6 are connected and the wire lobes 20, 22, 2
A weight G is attached to each tip of 4 and 26. The wire ropes 20, 22, 24, 26
is guided in the horizontal direction by a number of rope pulleys 28 rotatably supported on the upper end of the tower body 2. Approximately at the center of the open upper end of the tower body 2,
A sheet guide roller 30 is rotatably supported via a horizontal rod 32 installed on the tower body 2.

34, 36, 38, 40 are a pair of guide rollers rotatably supported on both sides of the tower main body 2, and the wire ropes 20, 22, 24, 26
passes between the guide rollers 34, 36, 38, and 40, and hangs down due to the weight of the weight G. The guide rollers 30 and 34, 36, 3
8, 40 are nonflammable sheets 10, 12 attached to the tower body 2.
It constitutes a sheet guide mechanism that guides the upper end in the horizontal direction. Normally, the noncombustible sheets 10, 12 are completely wound up on the winding shafts 6, 8, and the upper end of the tower body 2 is in an open state.

The solenoid 21 is electrically connected to a fire alarm push button switch 42, and when the switch 42 is pressed to turn on, the operating shaft 21a of the solenoid 21 resists the return spring force as shown in FIG. The claw members 18, 19 are driven downward.
The actuating shaft 21a is configured to be disengaged from the actuating shaft 21a. Incidentally, instead of the weight G, a coil spring may be used to pull the wire ropes 20, 22, 24, and 26 downward.

In the above configuration, if a fire occurs in the tower body 2 and the button switch 42 is pressed, the ratchet wheel 1
4 and 16 are in a free rotation state, and the wire rope 2
0, 22, 24, and 26 are moved downward by the weight of the weight G, as shown in FIG. The tower body 2 is guided by guide rollers 30 and drawn out, and the upper open part of the tower main body 2 is covered with a nonflammable sheet 1.
0,12. Note that the switch 42 is not particularly limited to a manually operated push button switch.

As mentioned above, in this invention, since the upper end of the tower body is open, it is possible to maintain good ventilation inside the tower body and reduce construction costs.Moreover, in the event of a fire, The non-combustible sheet has the advantage of being able to prevent flying flames.
