=== First Embodiment ===
FIG. 1 is a plan view showing an architectural space 1 that is a target for smoke shield arrangement arrangement according to the first embodiment. As shown in the figure, the building space 1 is partitioned into a passage 10 and a chamber 20.

The passage 10 includes an evacuation entrance 14 at the boundary with the evacuation space 12 where occupants evacuate when a disaster such as a fire occurs.
The chamber 20 includes a passage entrance 22 for connecting to the passage 10 at any location of the passage 10.

FIG. 2 is a flowchart showing the procedure of the design method of the present embodiment.
First, linear passage sections 10A, 10B, and 10C are specified by dividing the passage 10 with a bent portion (S202). Here, the linear shape of the passage section 10 refers to a passage shape with good visibility, and includes a substantially straight passage shape such as a passage having a curved outer edge portion of the passage.

  It is determined whether each end of the passage sections 10A, 10B, and 10C is connected to the evacuation entrance 14 or another passage section 10A, 10B, and 10C (S204), and if not connected (S204: NO) The design is redone (S222). On the other hand, when both ends of each passage section 10 are connected to the evacuation entrance 14 or another passage section 10A, 10B, 10C (S204: YES), first, the first room serving as an evacuation start point is selected ( S206, S208).

  Then, the passage section 10A connected to the first room via the passage entrance 22 is identified (S210), and all the passage sections 10 on the first route from the passage section 10A to the first evacuation entrance 14A are identified ( S212). In the case of FIG. 1, the first room is indicated by “(1)”, and the passage section 10 on the first route is only the passage section 10A. Further, all the passage sections 10 on the second route from the passage section 10A to the second evacuation entrance 14B are specified (S214). In the case of FIG. 1, it is passage area 10A, 10B, 10C.

  For the passage section 10A on the first route and the passage sections 10A, 10B, and 10C on the second route, it is determined whether there is no overlap other than the passage section 10A to which the first room is connected (S216). If there is (S216: YES), the design is performed again (S222). If there is no overlapping passage section 10 (S216: NO), the process proceeds to S218. In the example of FIG. 1, there is no overlap between the passage section 10A on the first route and the passage sections 10A, 10B, and 10C on the second route other than the passage section 10A to which the first room is connected (S216: NO).

  When the above work is performed for all M rooms 10 in the building space (S218: YES), the process ends. On the other hand, when the above operation is not completed for all the chambers 10 (S218: NO), the operation from S210 to S216 is repeated when the second chamber of the next chamber 10 is the starting point of evacuation (S220). Furthermore, the operations from S210 to S216 are repeated in the case where all the rooms 10 from the 3rd room to the Mth room are the starting point for evacuation (S218, S220).

  According to the present embodiment, the partition of the building space 1 can be designed so that there is no other than the passage section to which the room where the overlapping section is selected is connected in any evacuation route from any room 10.

  In other words, if there are two or more evacuation routes with no overlapping sections, the occupant can evacuate through another evacuation route even if there is an inaccessible portion on any evacuation route. A passage section connected to a certain room is included in any evacuation route, but the evacuation route from one room to one end of the passage section overlaps with the evacuation route from one room to the other end. There is no route. Therefore, even if there is an inaccessible part in a passage section connected to a certain room, the occupant can evacuate to the evacuation space.

  Moreover, according to this embodiment, the partition of the building space 1 can be designed so that there is no overlapping section in the evacuation route from all the rooms 20 from the first room to the M room in the building space.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment, The deformation | transformation as shown below is possible in the range which does not deviate from the summary.

  The shape of the passage in the first embodiment is a U shape, but the shape of the passage is not limited to this, and may be an L shape, a B shape, or a T shape.

  FIG. 3 is a plan view showing the building space 2 when the passage shape is L-shaped. As shown in the figure, the passage section 10A and the passage section 10B are specified at the bent portion of the passage 10, and the chamber 20 serving as an evacuation start point is provided in the first evacuation route and the second evacuation route as in the first embodiment. It is confirmed whether there is no overlapping passage section 10 other than the passage section 10 to be connected. In addition, evacuation entrances 14A and 14B are respectively provided at the end of the passage 10 so that the evacuation space 12 can be evacuated.

  Thus, even if the shape of the passage 10 is L-shaped, the partition of the building space 2 can be designed so that there is no overlapping section in any evacuation route from any room 10.

  FIG. 4 is a plan view showing the building space 3 when the shape of the passage 10 is a T-shaped branch. Evacuation entrances 14A, 14B, and 14C are provided at the end portions of the three passages 10, respectively, so that they can evacuate to the evacuation space 12. As shown in the figure, the passage section 10A and the passage section 10B are specified at the bent portion of the passage 10, and the chamber 20 serving as an evacuation start point is provided in the first evacuation route and the second evacuation route as in the first embodiment. It is confirmed whether there is no overlapping passage section 10 other than the passage section 10 to be connected.

  Thus, even if the passage 10 has a branch, the partition of the building space 3 can be designed so that there is no overlapping section in at least two evacuation routes from any of the chambers 10. For example, when a route from a certain room 20A to the evacuation entrance 14A is a first evacuation route and a route from the room 20A to the evacuation entrance 14B (or 14C) is a second evacuation route, the passage section is on the first evacuation route Only 10A and on the second evacuation route are passage sections 10A and 10B. Therefore, it can be confirmed that there is no overlapping passage section 10 other than the passage section 10A to which the room 20A that is the starting point of evacuation is connected, and it can be confirmed that there is no overlapping section in at least two evacuation routes.

  FIG. 5 is a plan view showing the building space 4 in the case where the shape of the passage 10 is a circular-shaped square shape. As shown in the figure, the passage section 10A, the passage section 10B, the passage section 10C, and the passage section 10D are identified at the bent portion of the passage 10, and the first evacuation route and the second evacuation route are evacuated as in the first embodiment. It is confirmed whether there is an overlapping passage section 10 other than the passage section 10 to which the chamber 20 that is the starting point of the connection is connected. In addition, it can evacuate to the evacuation space 12 such as an emergency stairs from a plurality of passage sections.

  Thus, even if the passage 10 is a circulation type, the partition of the building space 4 can be designed so that there is no overlapping section in any evacuation route from any room 10.

  Furthermore, even with these combined passage shapes, it is possible to design the partition of the building space so that there is no overlapping section in the evacuation route from any room 10 as described above.
