The staircases are arranged near the ends of the core part, and are located on the side of the shared corridor facing the evacuation route leading to the staircase located on the U-shaped opening side through the crossing corridor and the U-shaped opening part. Since an evacuation route that leads to the stairs through the shared corridor is formed, two short-distance evacuation routes are secured in an emergency, and safety in terms of disaster prevention is improved. It is also possible to selectively use two steps through the core passage.
(5) According to the invention according to claim 5, the height of the roof portion of the elevator installed in the core portion gradually decreases from the side of the passageway toward the side of the common hallway located on the side facing the elevator. Since the bank is divided into a plurality of banks, it is possible to improve the lighting and ventilation for the dwelling unit that is located on the side of the common corridor located on the side opposite to the side of the crossing corridor and is originally difficult to obtain lighting.

First, the main features of a building to which the present invention is applied will be described with reference to the drawings.
A building 1 configured as an apartment house shown in FIG. 1 includes a building body 100, a crossing corridor 10, and a core 20.
As shown in FIG. 1A, the building body 100 includes a building body central part 110 and two building body protrusions 120 bent from both ends of the building body central part 110. The floor plan of the reference floor is bent in a substantially U shape.
In the building main body 100, the common hallway 3 is arranged in a substantially U shape in plan view on the inner peripheral side, and a dwelling unit zone 2a in which a plurality of dwelling units are continuously arranged along the common hallway 3 is formed.
The passage corridor 10 is arranged as a long and narrow corridor that connects the common corridors 3 of the two projecting main body projecting portions 120 facing each other, and the passage corridor 10 and the common corridor 3 of the central portion 110 of the building body are only the length of the core portion 20. Separated and parallel (indicated by CL in FIG. 1 (a)). The core portion 20 forms an elongated belt-like floor plan shape (indicated by the width CB * the length CL in FIG. 1A), and the substantially central portions of the common corridor 3 of the passage corridor 10 and the central portion 110 of the building main body. Are crossed and tied. The crossing corridor 3 and the core portion 20 are connected to form a substantially T shape in plan view.
The building body portion 100 having a substantially U shape in plan view forms a large space (indicated by the length B of the building body central portion 110 in FIG. 1A * the length L of the protruding portion of the building body 120). However, since the crossing corridor 10 and the core part 20 having a substantially T shape in plan view are arranged, two divided vents 4 a and 4 b are formed on both sides of the core part 20. Since both sides of the transfer corridor 10 are external spaces in which no dwelling units are arranged, horizontal lighting and ventilation can be obtained for the two divided vents 4a and 4b via the transfer corridor 10.

As shown in FIG. 1B, the core portion 20 includes a passage 20a, a staircase 40, and a plurality of elevators 30. Since the passage 20a of the core 20 crosses and connects almost the central parts of the common corridor 3 of the crossing corridor 10 and the central part 110 of the building body, the common corridor of the corridor 20a of the core part 20 and the common corridor 10 and the building main part 100 is used. 3, a horizontal movement path (human passage) having a substantially letter shape in plan view is formed. In addition to the sun-shaped horizontal movement path, the common corridor 3 of the building body protruding portion 120 is extended to the tip of the building body protruding portion 120 by a desired length (indicated by L1 in FIG. 1A). Can be extended.
The two stairs 40, 40 are located in the core part 20 so that the evacuation route from the dwelling unit to the stairs of the building main body part 100 is shortened, and in the vicinity of both ends of the core part 20 near the crossing corridor 10 and the common corridor 3. Are spaced apart from each other.
Therefore, the evacuation route from the dwelling unit to the two stairs 40, 40 is in the dwelling unit having the longest evacuation distance, and reaches the stairs on the side of the crossing corridor via the common corridor 3 and the crossing corridor 10 (see FIG. 2 (bold broken line indicated by R1 in FIG. 1B) and a second evacuation route (thick broken line indicated by R2 in FIG. 1B) that reaches the stairs on the shared hallway side via the shared hallway 3 A short evacuation route is secured. That is, the longest evacuation distance becomes shorter and the evacuation distance from each dwelling unit is averaged as compared with the case where the core portions are provided at both ends of the building main body protrusion 120 as in the prior art disclosed in Patent Document 1. (Variation is reduced). For this reason, even if the planar shape of the building main body 100 is large and the total length of the common corridor 3 is long (for example, more than 100 m), there is no need to increase the number of steps to 3 or more. It is possible to easily cope with the fact that the evacuation route from the dwelling unit to the stairs on each floor is required to be a predetermined length (usually 50 m) or less according to the law.

As described above, the core portion 20 including the staircase 40 and the elevator 30 lifting / lowering equipment is disposed in the substantially central portion of the building main body portion 100. Therefore, it has the convenience that the approach flow line between each dwelling unit and the elevator 30 becomes shorter at all times, and the disaster prevention excellence that the evacuation route from each dwelling unit to the stairs 40 becomes shorter in an emergency.
And it has the two divided | segmented blow-throughs 4a and 4b on both sides of a core part, and the lighting and ventilation of the horizontal direction with respect to the blow-throughs 4a and 4b are obtained via the passageway 10. Furthermore, when the passage corridor 3 is located on the north side, it is possible to make use of the feature of the building main body 100 that is substantially U-shaped in plan view and that does not have a dwelling unit (no sunshine dwelling unit) facing only the north side.
Moreover, since the core part 20 has arrange | positioned several elevators along the channel | path 20a between the two stairs arrange | positioned in the planar view both ends vicinity, it forms the elongate strip | belt-shaped floor plane shape. However, since the corridor 10 and the core part 20 form a substantially T-shaped floor structure in plan view, horizontal deformation and torsional deformation during an earthquake in the floor plane of the core part 20 can be suppressed. it can.

  Hereinafter, more specific preferred embodiments of the present invention will be described with reference to the drawings. Note that the same reference numerals are used for the same elements in the drawings, and description thereof may be omitted as appropriate.

  FIG. 2 is a plan view schematically showing a reference floor of the multi-layered building (apartment house) according to the first embodiment.

  As shown in FIG. 2, the building 1 (building body part) configured as an apartment house is formed in a U-shape in plan view by bending an opposing vertical composition plane that forms a row direction, It is the structure provided with both ends. The dwelling unit zone formed by the dwelling units 2 arranged continuously in the vertical direction in the vertical direction is also U-shaped and has dwelling units at both ends. The opposing vertical composition is usually formed by a ramen structure, but is not limited by the type of structure. The U-shape refers to a shape having an opening cut out in a part of an annular shape surrounding the space, and is not strictly interpreted as an exact Roman U-shape. The bending angle can be changed as appropriate. The number of floors of the building 1 is not particularly limited, although it is suitable for high-rise to high-rise housing.

  A common corridor 3 is arranged inside the dwelling unit 2, and atriums 4 a and 4 b are provided inside the common corridor 3. The shared corridor 3 may be arranged on either the outer side or the inner side of the inner peripheral vertical construction surface. The blow-throughs 4a and 4b will be described in detail later. Reference numeral 6 denotes a balcony.

  A crossing corridor 10 is provided that connects the common corridors 3 and 3 facing each other across the U-shaped opening 5. This crossing corridor 10 is located in the opening 5 and is different from the common corridor 3 in that it is not provided along the dwelling unit 2. The crossing corridor 10 is constructed using pillars or the like facing each other with the opening 5 interposed therebetween, but the structure is not particularly limited. However, it is important that the transit corridor 10 has a structure in which the lighting is obtained in the horizontal direction (horizontal direction) from the outside of the building into the atriums 4a and 4b. Preferably, the side surfaces are open, which allows ventilation in the lateral direction between the vents 4a and 4b and the outside of the building on the opposite side. If only daylighting needs to be obtained, a transparent screen, a glass window, or the like may be provided on the side wall.

And the elongate strip | belt-shaped core part 20 which connects the substantially center part of the passage corridor 10 and the common corridor 3 located in the opposite side is provided. The core unit 20 includes a staircase 40, lifting equipment such as an elevator, and other shared equipment or facilities. In the core portion 20, an elevator 30 is installed at an intermediate portion in the longitudinal direction. The elevator 30 is located approximately at the center in the longitudinal direction of the core portion 20.
With this configuration, a short distance from the dwelling unit located on the U-shaped opening 5 side and the dwelling unit located on the U-shaped bottom side, to the elevator 30 installed on the belt-shaped core unit 20 from either side dwelling unit. The flow line is formed, and the flow line distance from each dwelling unit 2 to the elevator 30 can be averaged to reduce the inequality between the dwelling units. Moreover, since there is no dwelling unit which touches the elevator 30, the noise of the elevator 30 can be made difficult to reach the dwelling unit 2. The core unit 20 can be provided with an emergency elevator other than an elevator that is always used, a garbage storage, and other shared facilities or spaces.

In the illustrated example, the core portion 20 has a passage 20a at the center thereof, and communicates the crossing corridor 10 with the common corridor 3 located on the opposite side. The passage 20a is a so-called inner corridor, and the elevator 30 and the stairs 40 are arranged on both sides thereof. The passage 20a, the crossing corridor 10, and the common corridor 3 form a horizontal movement path that is substantially sun-shaped in plan view. Conveniently, movement through the core section on the same floor is ensured and choices of movement routes are increased.
The core portion 20 is provided with a staircase 40. The staircase 40 is disposed on both sides of the elevator and near the end of the core portion, and faces the evacuation route that leads to the staircase located on the U-shaped opening side through the crossing corridor and the U-shaped opening portion. An evacuation route that leads to the stairs located on the side of the shared hallway is formed through the shared hallway. Two short-distance evacuation routes are secured in an emergency, improving safety in terms of disaster prevention. It is also possible to selectively use two steps through the core passage.
The structures of the passageway 10 and the core portion 20 can be selected in accordance with the structure of the building body such as reinforced concrete or steel reinforced concrete. Since the structure having a T-shape in plan view formed by the crossing corridor 10 and the core portion 20 can be configured as a structural housing integrated with the main body portion of the U-shaped building 1, the lighting and ventilation to each dwelling unit is good. Thus, the rigidity of the building 1 can be increased.

  The strip-shaped core portion 20 is provided with divided vents 4a and 4b on both sides thereof. The atriums 4a and 4b are spaces without a floor communicating from the lower floor to the top floor of the building. The lighting through the passageway 10 is obtained by the blow-throughs 4a and 4b to the dwelling unit 2 facing the blow-throughs 4a and 4b. Moreover, the lighting and ventilation through the passageway 10 are obtained by opening the side surface of the passageway 10 to the dwelling unit facing the atriums 4a and 4b. Also about the dwelling unit 2 in the position where the core part 20 is connected, it is comprised so that the blower 4a, 4b surface side may not be completely covered by the elongate strip | belt-shaped core part 20, Therefore, with respect to all the dwellings Both sides (the surface on the inner peripheral side of the building with the vents 4a and 4b and the surface on the outer peripheral side of the building with the balcony 6) can be daylighted. It should be noted that a transparent roof (ceiling) may be provided at the top of the vents 4a and 4b to form an atrium.

  The second embodiment shown in FIG. 3 is a modification of the first embodiment shown in FIG. 2, and the position of the passageway 10 is slightly closer to the dwelling unit located at both ends compared to the first embodiment. The depth is long. The elevator 30 installed in the middle part in the longitudinal direction of the core unit 20 is divided into two banks that are separated in the longitudinal direction.

The third embodiment shown in FIG. 4 is a modification of the second embodiment shown in FIG. 3, and the configuration of the core portion 20 is slightly different. The passage 20a is a so-called one-side corridor, in which an elevator 30 and a staircase 40 are arranged on one side, and the width of the core portion 20 is formed shorter.
In addition, as shown with a broken line in FIG. 3, FIG. 4, each edge part (or one edge part) position of the building which makes a U-shape can be extended suitably, and a dwelling unit can also be provided there. This is advantageous in that, in the case where the commercial value differs depending on the regional characteristics, more dwelling units, and dwelling units that can also be both-sided-lighted, can be arranged in the high-valued commercial direction.

  Example 4 shown in FIG. 5 shows a modification of Example 2 shown in FIG. 3, and shows an application example in the building 1 having a larger site area and a larger number of units per floor. Reference numeral 41 denotes an emergency elevator.

  The fifth embodiment shown in FIG. 6 shows a modification of the second embodiment shown in FIG. The shape of the building 1 (building body part) is a U shape in plan view, but the bending angle of the U shape is an obtuse angle, and both ends thereof are widened. An example in which a U-shape can be modified according to the site shape or the like is shown. Note that the staircase 40 on the side of the staircase 10 located in the core portion 20 is arranged outside the crossover corridor 10.

It is a longitudinal cross-sectional view in d line position (each shown with an end elevation).
The elevator 30 installed in the core portion 20 includes a plurality of banks A, B, C in which the height of the roof portion gradually decreases from the side of the passageway 10 toward the side of the shared corridor 3 positioned on the opposite side. It is divided into two. Bank A is used for raising and lowering the higher floor, bank B is used for raising and lowering the middle floor, and bank C is used for raising and lowering the lower floor. The elevators 30 that constitute the banks A, B, and C are disposed on both sides of the central passage 20 a of the core portion 20. The central passage 20a and the bank A of the core part 20 are provided up to the top floor, but the bank B is provided up to the middle floor, the bank C is provided up to the lower floor, and the height of the roof of the bank corresponds to the top floor of each bank. It ends at the height. The number of banks can be changed as appropriate according to the number of floors of the building. Moreover, the position in the longitudinal direction of the core part 20 of a bank can be adjusted suitably.
With the above configuration, for the dwelling units (the middle floor and some dwelling units on the upper floors in the example shown), which are located on the side of the shared corridor 3 that is originally the most difficult to reach daylighting, that is, on the side facing the crossing corridor 10 Lighting from the heaven direction will be brought about, and the lighting and ventilation in the dwelling unit can be improved.
