FIG. 3 is a perspective view of a stairs room, an evacuation room, a stairs, and an evacuation tool of a building evacuation facility according to a modification of the first embodiment of the present invention. FIG. 4 is an enlarged perspective view showing only the starting end portion of an in-building evacuation facility according to another embodiment of the present invention. FIG. 5 (a) is a front sectional view of the evacuation tool of the present invention, and FIG. 5 (b) is a perspective view of only the slide.

A first embodiment of the present invention will be described with reference to FIG.
FIG. 1A is a plan view showing a staircase 1 connected to a corridor 2 on a normal floor. In this embodiment, the specific floor evacuation room 3 is provided adjacent to the landing 13 of the staircase 1 on the specific floor.
21.22 is a fire door that partitions the staircase room 1 and the evacuation room 3 from the hallway 2.
The specific floor here refers to the floor where a childcare room that can not evacuate by itself, a nursery that keeps infants, a sick room that can not walk, and a serious sick person, etc. is provided, in this example Is the third floor. The building evacuation facility of the present invention is a facility provided in the building to safely and quickly evacuate people who cannot evacuate by themselves from this specific floor to the first floor or escape floor of the basement floor. is there.

Reference numeral 11 denotes an intermediate floor landing 11 provided between the third floor and the fourth floor, and the arrow shown in FIG.
The specific floor evacuation room 3 includes a first evacuation room 31 that is substantially at the same level as the floor of the specific floor, a second evacuation room 32 that is a predetermined dimension lower than the floor surface of the first evacuation room, and these It is a three-dimensional section composed of an escape chamber staircase 33 connecting the first and second escape chambers 31.32.
Here, “substantially the same level” is a concept including a barrier-free structure in which a step is eliminated by an inclined plate so that a stretcher or a wheelchair can move.

  In the building, at least from the specific floor to the escape floor such as the first floor and the basement floor, a tilting elevator 12.14.16.18.20 such as stairs and escalators is disposed. The evacuation device 4 is suspended from the oblique lifting device and the lower surface of the landing.

On the other hand, an escape floor evacuation chamber 5 is shown in the vicinity of the landing hall 15 on the first floor which is the escape floor or the intermediate floor 15 of the first floor and the second floor, with the floor surface set at the escape floor level or a level close thereto. It is installed inside.
In this embodiment, the escape floor evacuation room 5 is provided on the rear side of the landing 19 as viewed from the down direction of the stairs 18 as shown in FIG. It may be provided on the right side of the landing 19 or may be provided below the stairs 20.
In short, it is only necessary to secure a necessary space at a position and height that can safely and reliably accommodate evacuees such as infants who slide down the slide in consideration of the layout of the building.

The evacuation tool 4 shown in FIG. 2.4 includes a slide base 41 having a bottom plate 42, a side plate 43, and a handrail 44, and a plurality of suspension tools 45 for attaching the slide base 41 to the lower surface of the staircase 12.14.16. ing. Reference numeral 49 denotes a deceleration surface of the slide 41.
In addition, in order to prevent the user of the evacuation tool 4 from falling, the interval between the handrails can be set to a predetermined size, or a surface material such as a wire net can be provided on the side surface of the slide.
The lifting tool 45 includes two vertical members 46.46 suspended from the outer surfaces of both side plates 43.43 of the slide base 41 at a predetermined interval and a horizontal member 47 connecting the lower ends of these vertical members. A plurality of pieces are fixed to the bottom surface of the slide table 41 at appropriate intervals in the slide direction.

A long cap nut (not shown) is rotatably attached to the upper ends of the two vertical members 46.46 that are spaced apart from each other in the orthogonal direction of the slide 41, and the stairs 12.14.16. The bolts welded to the Sasara girders 48 can be screwed together.
The evacuation tool 4 has a lower surface of the slanting lifting tool by rotating the long bag nuts of the plurality of suspension tools and adjusting the screwing length in order to moderate the slope angle and sliding speed of the sliding surface. And a distance to the sliding surface of the bottom plate is suspended and installed with an appropriate predetermined dimension. The long cap nut is secured by a double nut or the like.

The starting end 411 of the slide 41 has a lower surface of a predetermined dimension from the lower end of the skew elevator that connects the landing on the specific floor and the landing on it, that is, the third floor and the fourth floor as shown in FIG. The lower floor of the staircase 12 connecting the landing hall 11 on the middle floor and the landing hall 13 on the third floor is suspended from the lower surface of the staircase to the sliding surface of the bottom plate by about 1 m. This ensures a sufficient overhead height for evacuees and a necessary overhead height for daily stair users. Similarly, there are X stairs that alternately install two stairs that save space and increase evacuation capacity, but the present invention can move to the escape floor without walking for infants and sick people who are difficult to walk, It is possible to deal with the case where the floor height is too low for the X staircase. When the floor height is 4000 mm, the distance from the lower surface of the stairs to the slip surface can be up to 1400 mm.
The bottom plate level of the start end 411 is the same level as that of the second evacuation chamber 32 of the escape floor evacuation chamber 3, so that the level difference is eliminated and quick escape is achieved.

  This evacuation tool 4 is attached to the lower surface of a direct folding type staircase having a structure in which a straight staircase is folded back at a landing that is formed on each floor and an intermediate floor. For this reason, it has the turning part 412 which folds in the opposite direction from one direction on the lower surface of each landing.

  Also, since the entrance to the slide is directed to the second evacuation chamber 32 and faces the second evacuation chamber, the evacuee turns to the left immediately after moving from the evacuation chamber to the slide, and as soon as it begins to slide It reaches the above-mentioned turning part on the lower surface of the landing on the specific floor, turns back slowly and turns down and slides in the opposite direction.

In this turning part 412, the slope of the sliding face is adjusted and attached to the lower surface of the staircase so that the turning speed can be reduced and the turning speed can be reduced while slowing down at the linear part of the slide.
In other words, it is designed so that it can slide down while repeating the motion of accelerating to some extent at the linear part of the slide and decelerating at the turning part.
When the staircase width is wide, the lateral distance perpendicular to the staircase descending direction of the turning part 412 becomes long. Therefore, a necessary sliding speed may be secured by adding a considerable gradient to the turning part.

On the other hand, the deceleration surface 49 of the terminal portion 413 of the evacuation tool 4 faces the escape floor evacuation room 5 provided adjacent to the landing floors on the first and second floors.
The level of the deceleration surface 49 may be the same as or slightly higher than the level of the floor of the escape floor evacuation room 5, but the point is to select a height at which the evacuation assistant can quickly accommodate the evacuees. It is.

Next, with reference to FIG. 1C and FIG. 3, a modification of the first embodiment will be described.
The specific floor evacuation room 3 'of this modification is installed adjacent to the intermediate floor landing 11 provided between the third floor and the fourth floor.
The specific floor evacuation room 3 ′ includes a first evacuation room 31 ′ that is substantially at the same level as the floor of the specific floor, and a second evacuation room 32 ′ that is a predetermined dimension higher than the floor surface of the first evacuation room. And an evacuation chamber stairway 33 'connecting the first and second evacuation chambers 31.32.

The slide 41 has substantially the same configuration as that of the first embodiment, except that the starting end of the slide 41 of the first embodiment extends to the wall surface near the intermediate floor landing 11 of the specific floor evacuation chamber 3 ′. This is also substantially the same in terms of operation.
As is clear from the above description, the specific floor evacuation room is functionally the same even if it is provided at either the landing 13 of the staircase 1 on the specific floor or the landing 11 of the intermediate floor with the upper floor.

  The second embodiment is an in-building evacuation facility that is employed when it is impossible or difficult to provide an evacuation room as in the first embodiment for any reason regardless of whether the building is an existing facility or a new facility. It is.

FIG. 3 is an enlarged perspective view showing only the starting end portion of the in-building evacuation facility according to the present embodiment. The present embodiment will be specifically described with reference to this figure.
The present embodiment is an in-building evacuation facility provided in a building in which slanting lifts are arranged from at least a specific floor of the building to the escape floor, and an evacuation provided with a bottom plate, a side plate, and a handrail A sliding surface of the bottom plate along the lower surface of the skew lifting device by means of a plurality of suspension tools, the upper end of which is attached to the lower surface of the skew lifting device and is suspended from the outer surface of the side plate with a predetermined interval. There is no difference in the basic configuration from the first embodiment in that it is suspended and installed with a distance up to a predetermined dimension.

That is, the evacuation tool 4 includes a slide 41 having a bottom plate 42, a side plate 43, and a handrail 44, and a plurality of hanging tools 45 for attaching the slide 41 to the lower surface of the stairs 12.14.
However, since the present embodiment does not have an evacuation room on a specific floor, even if the slide 41 is attached to the lower surface of the stairs 12.14..., There is no means for the evacuee to get on the slide 41.

Therefore, in this embodiment, several of the plurality of vertical bars 22 of the handrail 21 facing the upper and lower stairs of the stairs 14 are cut out to form the opening 23.
A characteristic configuration of this embodiment is that the opening 23 formed in the handrail 21 of the staircase functions as the entrance 411 of the evacuation tool.

Specifically, the entrance 411 that is the starting end of the slide 41 is directed to the opening 23 and faces the tread plate of the stairs 14.
Therefore, the evacuation assistant holds the refugee and stably places the evacuation person on the slide 41, and then pushes the back while changing the direction to the left. The movement after the start of sliding is the same as in the first embodiment. That is, it immediately reaches the turning part 412 on the lower surface of the landing on the specific floor, turns slowly while turning, and slides down in the opposite direction.

  Moreover, it is relatively easy to form an evacuation room on the escape floor that does not have a staircase connected to the basement floor. At this time, the terminal portion of the evacuation tool may be faced with an evacuation room formed on the escape floor.

However, when it is difficult to form an evacuation room on the escape floor as in the case where stairs connected to the lower floor of the escape floor are continuously provided, the terminal portion 413 of the evacuation tool 4 is set to It is good to form an opening part in the reverse positional relationship of the specific floor.
That is, an opening is formed in the handrail at the upper position of the stairs connecting the escape floor and the lower floor.
And the exit which is the termination | terminus part of the slide 41 suspended below the stairs which connects an escape floor and the upper floor faces the said opening.
At this time, it is important that the stop state is surely realized by increasing the slope of the deceleration surface 49 so that the evacuee cannot stop at the exit and be injured. .

  By constructing as described above, the in-building evacuation facility can be easily constructed even when evacuation rooms cannot be formed on both the specific floor and the escape floor.

  In the two embodiments described above, the evacuation device is attached to the lower surface of the straight folding type lifting / lowering device having a structure in which the straight type lifting / lowering device is folded back at the landing, and the evacuation device is unidirectionally connected to the lower surface of the landing. However, the present invention may be a straight-line type in which the skew lifting / lowering tool extends in a straight line regardless of whether or not there is a landing.

  In the present invention, the skew lifting / lowering tool is not limited to a staircase and may be an escalator. At this time, the opening is formed in a partition wall standing on the boundary.

Furthermore, by providing an emergency exit door on an appropriate lower floor of a specific floor, it becomes possible to cope with an emergency such as a failure occurring in the middle of the evacuation equipment.
Furthermore, it is possible to prepare the emergency evacuation doors on a plurality of floors to prepare for emergency response in detail.
