DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency evacuation facility of a type in which a slide is provided on an emergency evacuation stair.

[0002]

2. Description of the Related Art Conventionally, as a type of emergency evacuation equipment installed along an outer wall of a building or the like, a type in which a slide is provided on a spiral emergency evacuation staircase is known. This equipment has a structure in which slides are spirally provided along the inside of the spiral stairs. Since the emergency evacuation stairs and slide are integrated, it is necessary to install emergency evacuation equipment. In this case, there is an advantage that space can be saved in designing and cost can be reduced.

[0003]

However, some local governments do not allow the installation of spiral emergency evacuation stairs due to regulations, and in such local governments (for example, Tokyo, etc.) No spiral slide evacuation equipment with a slide can be installed. In general, emergency evacuation facilities with slides are particularly useful in facilities that require the assistance of the user when evacuating, such as hospitals, nursing homes for the elderly, and nursing homes for the elderly. In such a facility, when using the emergency evacuation equipment, a user of the slide needs to be assisted from the stairs side.

[0004] However, in the above-mentioned conventional equipment in which a spiral slide is provided inside the spiral staircase, the length of the inner spiral slide is greatly different from the length of the outer spiral staircase (spiral slide <spiral slide). Stairs), and there is a problem that it is difficult to assist the slide user from the stairs side. In other words, even when going down the same floor, the slide is much shorter in travel length, and it is much faster to slide down the slide compared to running down the stairs. It is not easy to assist a person from the stairs according to the descending speed. In addition, the spiral slide has a tendency to give a sense of fear to the user, and furthermore, the spiral emergency evacuation equipment provided with the slide has a spiral shape, so construction is required. There are also disadvantages such as complexity.

Accordingly, an object of the present invention is to provide an emergency evacuation facility in which the emergency evacuation stairs are not of a spiral type, enabling safe and quick evacuation in an emergency, and assisting a slide slide user from the stairs side. It is an object of the present invention to provide a slide-equipped emergency evacuation facility that is easy to perform, does not give a user a fear like a spiral slide, and is easy to construct itself.

[0006]

The features of the present invention for achieving the above object are as follows. [1] An emergency evacuation facility installed outside a building such as a building, wherein a direct-turn staircase has a structure in which a direct staircase is folded at a landing located in the middle of the upper and lower floors, and the emergency evacuation staircase. An emergency evacuation facility, comprising: a slide provided along substantially the entire length of the outside of the vehicle; and a slope provided on a slide provided outside the landing in the middle of the upper and lower floors.

[2] In the equipment of the above [1], the sliding surface of the slide portion provided outside the landing in the middle of the upper and lower floors is formed by a plurality of rotatable roller bodies arranged along the sliding surface width direction. An emergency evacuation facility characterized by the configuration. [3] The facility according to [1] or [2], wherein the plane shape of the landing in the middle of the upper and lower floors is configured to be substantially semicircular, and the slide part is provided in an arc shape along the landing. Evacuation equipment. Such an emergency evacuation facility of the present invention can be installed in any of a vertical installation type installed at right angles to the skeleton and a horizontal installation type installed in parallel with the skeleton.

[0008]

1 and 2 show an embodiment of an emergency evacuation facility according to the present invention, wherein B is a building such as a building, and A is the present invention provided along the outside of the building B. This is an emergency evacuation facility. The emergency evacuation facility A has a structure in which a straight staircase is folded back at the middle of the landing between the upper and lower floors.
A so-called "straight-back type" emergency evacuation staircase 1 and a slide 2 provided along substantially the entire length outside the emergency evacuation staircase 1 are provided. , Provided for each of the upper and lower floors. Therefore, the slide 2 constituting the emergency evacuation facility A of the present invention
Has a structure that is temporarily interrupted on each floor.

The emergency evacuation stairs 1 have a landing 3 in the middle of the upper and lower floors, and the landing 3 and each of the emergency evacuation exits on the upper and lower floors (or landings provided on the front of the landing) are directly connected (in a straight line). ) Has a structure connected by the stairs 5a and 5b, and therefore, the straight staircase constitutes a so-called straight-turn staircase in which the stairs are folded back at the landing 3. In the present embodiment, the landing 3 in the middle of the upper and lower floors has a substantially semicircular planar shape.

The slide 2 is provided along the substantially entire length outside the emergency evacuation stairs 1 including the stairs 5a and 5b and the landing 3. The slide 2 has stairs 5a,
Slide parts 20a, 20 provided along the outside of
b and a slide portion 21 provided along the outside of the landing 3 and connecting the slide portions 20a and 20b. The slide portion 21 provided outside the landing 3 has a slope (inclination). Thus, the slide 2 can be continuously slid down between the upper and lower floors. The slide 2 has side plates 22 on both sides of the slide surface.
have.

The slide portion 21 outside the landing 3 is provided in an arc shape along the shape of the landing 3 so that a user of the slide 2 can safely pass through the landing portion. The slide part 21 outside the landing 3 is a slide part 20.
Since the inclination is relatively small as compared with the sliding surfaces a and 20b, the sliding surface of the slide portion 21 is rotatable disposed along the sliding surface width direction so that the sliding surface can smoothly slide down. It is constituted by a plurality of roller bodies 6. The rotatable roller body 6 may be constituted by a roller body having a straight shape in the longitudinal direction. However, since the slide portion 21 is formed in an arc shape along the landing 3, the diameter of the landing 3 is reduced. It is preferable that the roller member is formed of a roller-like body.

Further, in order to prevent the user of the slide 2 from receiving a force that is pushed out of the slide 21 by the action of the centrifugal force, the slide surface of the slide 21 (as in the present embodiment, a roller). When the body 6 is provided, it is preferable that the sliding surface formed by the roller body has a downward slope toward the landing 3. Slide part 20a, 2
The sliding surface 12 of 0b may be constituted by a smooth surface such as a plate material,
In order to minimize the friction at the time of sliding down, for example, a sliding surface may be configured by arranging pipes along the slide longitudinal direction in the slide width direction.

In the emergency evacuation facility A of the present invention, the above-described structure including the emergency evacuation stairs 1 and the slide 2 is provided for each of the upper and lower floors.
b, which are erected on the lowermost base at both ends between
The main evacuation stairs 1 and the upper and lower ends of the slide 2 are fixed to the skeleton side by bolts and the like while being supported by the main pillar 7 of the book. By supporting the entire emergency evacuation facility with the two main pillars 7 in this way, it is possible to obtain excellent strength and durability in terms of structure.

A landing 4 is formed at the end of the emergency evacuation stairs 1 and the slide 2 that communicate with the emergency evacuation exit on each floor. The landing 4 may be provided as a structural part on the skeleton side. In the other drawings, 8 is an emergency evacuation facility A
A louver (protective body) covering the entire outside of the vehicle, 9 is a handrail of the stairs, 10 is a beam for the main pillar 7 to support a structural part such as a staircase and a landing.

FIG. 3 shows another embodiment of the present invention. In the embodiment shown in FIGS. 1 and 2, the emergency evacuation stairs 1 are perpendicular to the body surface in plan view. In the embodiment of FIG. 3, the emergency evacuation stairs 1 are provided so that the emergency evacuation stairs 1 are parallel to the frame surface in a plan view. A relatively large landing 11 is provided in front of the emergency exit on the skeleton side, and the upper and lower ends of the emergency evacuation stairs 1 and the slide 2 are fixed to the landing 11. I have. The landing 11 may be provided as a part of the emergency evacuation facility A, or may be provided as a part of a structural part on the skeleton side. Since other configurations are the same as those of the embodiment shown in FIGS. 1 and 2, the same reference numerals are given and the detailed description is omitted.

The emergency evacuation facility A according to the present invention as described above has the following advantages as compared with the conventional spiral evacuation facility. (1) Since the stairs and slides are of a straight-turn type, even local governments that do not allow spiral emergency evacuation stairs can be installed without any problems.

(2) Since the stairs and the slide are provided in parallel at right angles except at the landing between the upper and lower floors, when the slide user is assisted from the stairs side, the attendant is the user of the slide. It is only necessary to move by the same distance as that described above, so that the user of the slide can be easily assisted from the stairs side. On the other hand, at the landing between the upper and lower floors, there is a difference between the movement length on the slide side and the movement length on the stairs (landing) side. This part is a flat landing on the stairs side, and it is easy for attendants to move. That the travel length is [slide side]> [stairs (landing side) side], and that the travel length of the attendant is smaller than the user of the slide,
Usually, the slope of the slide part along the landing is less steep than the slope of the slide part along the stairs, so that the slide down speed of the slide user is reduced, and the like. Even at the landing, it is possible to extremely easily assist the user of the slide from the stairs side. Therefore, when viewed as a whole, there is an advantage that it is much easier for the user of the slide to assist from the stairs side than the conventional spiral type emergency evacuation facility.

(3) Since the slide is of a direct turn-over type, the user has less fear of a user than a conventional spiral slide. (4) In the construction of conventional spiral evacuation equipment, the workability is extremely poor because it is necessary to attach the treads of the spiral stairs one by one at the site, and installation of such treads is a work at a high place. Therefore, there was a problem in terms of work safety. On the other hand, since the emergency evacuation equipment of the present invention has a basic structure of a straight turn-around staircase, the main structural parts including the treads of the stairs can be assembled at a factory, which makes the construction easy and conventional. Work at high places such as that described above can be reduced, and high workability and work safety during construction can be ensured.

[0019]

As described above, the emergency evacuation facility of the present invention does not have the restrictions on installation as the conventional spiral evacuation facility because the stairs are not spiral, and it is safe and quick in emergency. In particular, there is a great advantage that it is much easier to provide a slide user with assistance from the stairs side as compared with a conventional spiral-type slide-equipped emergency evacuation facility. Moreover, since it does not give a sense of fear to the user like a spiral slide and is extremely easy to construct itself, it is suitable for emergency evacuation facilities of various buildings and facilities, especially hospitals, geriatric health facilities It is an emergency evacuation facility that is particularly useful in facilities such as special elderly nursing homes that require the assistance of a user when evacuating.
