DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evacuation device for evacuating to the outer periphery of a building such as a high-rise house in an emergency such as when a fire occurs.

[0002]

2. Description of the Related Art Conventionally, in a high-rise building, a balcony is continuously provided along the outer periphery of the building to form an evacuation passage, and the building is used as an emergency evacuation in the event of a fire or the like. Balconies could be evacuated clockwise or counterclockwise not only inside but also outdoors.

[0003] Therefore, as shown in FIG.
If a fire occurs near the entrance in one of the rooms 0, it is not possible to escape to the elevator 14 provided on the north side, so escape from the opening to the balcony 15 and turn left or right (the dotted line in the figure). (Shown in FIG. 3).

[0004] However, due to the problem of the sunshine of land and buildings adjacent to the north side of the high-rise building 10, the shade of the high-rise building 10 may be restricted, and the northeast side of the high-rise building 10 may be controlled. In some cases, a balcony for evacuation cannot be provided along the outer periphery of the building at the corners 11 and 12 on the northwest side. In this case, for example, it is conceivable to provide the evacuation passage 13 inside the corner of the building.

[0005]

However, if the evacuation passage 13 is provided diagonally inside the corner, the occupied area inside is reduced, and the room becomes a deformed room, which restricts the layout and lowers the utility value. There is a problem to say. As a result, the prices of condominiums and rentals are relatively high, which causes inconvenience in the construction plan.

[0006] As described above, the conventional high-rise building has a problem to be solved in that when the evacuation balcony is provided on the outer periphery of the building, it is limited by the shading regulation.

[0007]

The gist of the present invention for solving the above-mentioned problem of the movable evacuation balcony according to the present invention is to provide an evacuation balcony provided on both sides of a corner of a building, and to be provided at the ends of both balconies. An extendable movable extension is provided, the movable extension is extended toward a ridgeline of the corner, and the distal ends thereof are engaged with each other to form an evacuation passage , and the movable extension is provided.
Provided between the floor of the balcony and the floor of the movable extension
The sliding means and the movable extension in the horizontal direction
And the moving means .

The moving means is a combination of a manual moving means and an electric moving means; one of the movable extensions of the balconies is connected to the other movable extension. Is provided with a stopper for restricting horizontal movement.

[0009] According to the movable evacuation balcony according to the present invention, usually, at the corner of a high-rise building, a movable extension is accommodated in the balcony, and the shadow is not projected on the adjacent land for a predetermined time or more. In the event of an emergency, such as when a fire has occurred, when the shadow regulation has been cleared, the moving means operates together with the operation of the fire alarm, and the movable extension extends toward the ridgeline of the corner, and the tip ends of the movable extension extend from each other. Engage to form an evacuation passage. Therefore, a person can evacuate in either of the left and right directions through the evacuation passage.

[0010]

Next, an embodiment according to the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 3, the first embodiment of the present invention, for example, includes a balcony 6 of a northern opening 4 and a western opening 5 at a northwest corner of a high-rise building 10. , 7 are provided with movable extensions 8, 9.

The structure of the movable extension portions 8 and 9 can be variously formed by known means. In the first embodiment, for example, as shown in FIGS. In the description of the balcony 6, steel guide rails 2 and 2 are juxtaposed on the lower surface of the floor 6a along the longitudinal direction thereof, and the steel guide 8 and the movable floor 8 extend from the steel floor 8a of the movable extension 8 in the hollow of the guide rail 2. By fitting the flange portion of the standing support member 1,
The floor 8a of the movable extension 8 is suspended from the floor 6a.

The size of the floor 8a is, for example, about 1.2 to 1.5 m in width and about 2 to 4 m in length.
In addition, the part which the movable extension part 8 protrudes and protrudes from the balcony 6 is about 1-2 m. Since the overhang is cantilevered, it is necessary to ensure safety. For safety, a protective wall 8b is provided on the balcony 6 so as to overlap with the protective wall 6b.

As shown in FIG. 1, the balcony 6 is provided with a protective wall 18 in a normal state. One end of the protective wall 18 is rotatable through a hinge to the high-rise building 10 (the opening 4 side). It is preferable to rotate only in
And the other end is locked to the side wall of the balcony 6 by means such as a lock device.

As shown in FIG. 3, a moving rail (for example, a moving rail) is provided on the lower surface of the floor 8a.
H-shaped steel) 16 is fixed, and a rack 17 is provided on one side surface of the moving rail 16.

A gear 3a of the drive motor 3 is provided so as to mesh with the rack 17. The drive motor 3 is fixed to the wall surface of the high-rise building 10. And
The drive motor 3 is electrically connected to and controlled by a control device so as to operate in cooperation with an indoor fire hydrant and a disaster prevention management center.

The movable extension 9 provided on the west side of the high-rise building 10 is also suspended on the balcony 7 in the same manner as described above, and is provided with moving means.

The entire length of the movable extension 9 is longer than the length of the movable extension 8 by the width of the balcony 6, and as shown in FIG. 19, the distal end of the movable extension 9 is extended to the protection wall 8b of the movable extension 8.

Therefore, when the protective wall 9c of the movable extension 9 engages with the tip of the movable extension 8,
And is connected so as to be substantially flush with the protective wall 8b.

In addition, it is preferable to provide a stopper 8c at the tip of the movable extension portion 8 outside. The stopper 8c mechanically stops the extension of the distal end portion of the movable extension portion 9 to secure safety. The stopper 8c comes into contact with the protective wall 9c and / or the floor portion 9a of the movable extension portion 9. A rigid member is protruded. Therefore, the stopper 8c only needs to achieve its purpose, and there is no particular restriction on the shape and the like. Of course, it is preferable to provide a mechanical stopper in each of the movable extension portions 8 and 9 so as not to overhang.

Slides toward the corner of the skyscraper 10.

As shown in FIG. 2, the movable extension 8 reaches the corner ridge 19 and stops extending. The movable extension 9 extends beyond the corner ridge 19 and comes into contact with the stopper 8c. At the same time, the extension stops.

When a person escapes from the opening 4, the protection wall 18 is unlocked and rotated toward the opening 4 to open an evacuation route. The protection wall 8b and the protection wall 9
For safety, they are locked to each other at the contact portion.

As described above, since the movable extension portions 8 and 9 are connected to each other to form an evacuation passage, a person goes out of the opening portion 4 or the opening portion 5 to the balconies 6 and 7 and moves in either the left or right direction. Is to escape.

If the transmission signal for driving the drive motor 3 is cut off or the electric wiring is cut off and the drive motor 3 is not automatically driven, for example, the drive mounted on the wall of the building may be used. The shaft is manually rotated by a handle or the like, and the movable extension portions 8 and 9 are simultaneously extended by a gear transmission mechanism or a gear and chain transmission mechanism.

As a second embodiment of the present invention, a groove which engages with the tip of the floor 8a of the movable extension 8 and the tip of the floor 9a of the movable extension 9 and fits into the groove. An engaging portion may be provided. Thereby, the strength of the evacuation passage is also reinforced.
