If the building 100 has four or more floors, the predetermined reference floor 10, the first upper floor 20 and the second upper floor 30 need not be the first to third floors. If the building 100 has four or more layers, the atrium space 40 may extend over at least three layers, or may extend over four or more layers.

Note that, as shown in FIGS. 1 to 3, the atrium space 40 of the present embodiment is arranged to be biased toward one side of the building 100 in plan view. That is, as shown in FIGS. 2 and 3, the atrium space 40 of the present embodiment is not surrounded by the first upper story 20 and the second upper story 30 in plan view, and is surrounded by the first upper story 20 in plan view. and on only one side (for example, the west side) of the second upper floor 30 . The position of the atrium space 40 in the building 100 is not limited to the position shown in this embodiment, and may be, for example, an atrium space surrounded by upper floors. However, as in this embodiment, the atrium space 40 is not surrounded by the first upper story 20 and the second upper story 30 in plan view, and at least a part of it is adjacent to the outer peripheral wall 101 of the building 100. is preferred. By doing so, light can be easily taken in through the openings provided in the outer peripheral wall 101 and the glass curtain walls constituting the outer peripheral wall 101, and the atrium space 40 can be made into a bright and open space. It can be seen from outside the building.

The first upper story 20 has a first adjacent part 21 that is visible from the atrium space 40 . As shown in FIG. 2 , the first adjacent portion 21 is adjacent to the atrium space 40 and extends along the atrium space 40 in plan view.

The second upper floor 30 has a second adjacent portion 31 that is visible from the atrium space 40 . As shown in FIG. 3 , the second adjacent portion 31 is adjacent to the atrium space 40 and extends along the atrium space 40 in plan view.

The first adjacent portion 21 includes, in a plan view, a partition line L1 that separates the first upper floor 20 and the atrium space 40, and a pillar street passing through the centers of the plurality of pillars 25 arranged along the atrium space 40. It means an area sandwiched between the reference line L2, which is the core. The first adjacent portion 21 of the present embodiment is a first passage that is sandwiched between the partition line L1 and the reference line L2 in a direction orthogonal to the reference line L2 in plan view (hereinafter referred to as "passage width direction A"). It is composed of a portion 21a and a first stage portion 21b.

In addition, the second adjacent portion 31 passes through the division line L3 that separates the second upper floor 30 and the atrium space 40 and the centers of the plurality of pillars 35 arranged along the atrium space 40 in a plan view. It means an area sandwiched between the reference line L4, which is the pillar-street core. Note that the reference lines L0, L2, and L4 of the present embodiment are aligned in plan view. The second adjacent portion 31 of the present embodiment includes a second passage portion 31a and a second passage portion 31a sandwiched between the partition line L3 and the reference line L4 in a direction perpendicular to the reference line L4 in plan view (the same direction as the passage width direction A). It is composed of a stage portion 31b.

Here, the second adjacent portion 31 has a portion that does not overlap the first adjacent portion 21 in the vertical direction. In other words, in plan view, the first adjacent portion 21 and the second adjacent portion 31 have portions that do not overlap each other. In this way, the first adjacent portion 21 arranged on the first upper story 20 and the second adjacent portion 31 arranged on the second upper story 30 are arranged so as to have portions that do not overlap in the vertical direction. Therefore, both the first adjacent portion 21 and the second adjacent portion 31 on different floors can be visually recognized from the position of the predetermined reference floor 10 through the atrium space 40 . Therefore, a person on the standard floor 10 recognizes the difference in the position, shape, etc. of the first adjacent portion 21 and the second adjacent portion 31 in a plan view, and is able to access the first upper floor 20 and the second upper floor 30. intriguing. As a result, the effect of inviting people on the standard floor 10 to the upper floor can be expected.

More specifically, in this embodiment, the second stage portion 31b has a portion that does not vertically overlap the first stage portion 21b. By doing so, a person on the reference floor 10 can more easily recognize the difference in the positions, shapes, etc. of the first adjacent portion 21 and the second adjacent portion 31 in a plan view. Therefore, people on the base hierarchy 10 are more likely to be interested in the first upper hierarchy 20 and the second upper hierarchy 30 . This can be expected to have the effect of attracting more people to the upper floors.

As described above, the first adjacent portion 21 includes the first stage portion 21b that protrudes toward the atrium space 40 from its surroundings. More specifically, the first stage portion 21 b of the present embodiment is a portion of the first adjacent portion 21 that protrudes toward the atrium space 40 . The first passage portion 21a of the present embodiment is a portion of the first adjacent portion 21 other than the first stage portion 21b. That is, the first stage portion 21b of the present embodiment is a portion that protrudes toward the atrium space 40 from the first passage portion 21a.

The second adjacent portion 31 also includes a second stage portion 31b that protrudes toward the atrium space 40 from the surroundings. More specifically, the second stage portion 31 b of the present embodiment is a portion of the second adjacent portion 31 that protrudes toward the atrium space 40 . The second passage portion 31a of the present embodiment is a portion of the second adjacent portion 31 other than the second stage portion 31b. That is, the second stage portion 31b of the present embodiment is a portion that protrudes toward the atrium space 40 from the second passage portion 31a.

In addition, in the 1st adjacent part 21, there may be multiple 1st stage parts 21b. Moreover, in the second adjacent portion 31, there may be a plurality of second stage portions 31b. As described above, in the building 100 including the plurality of first stage portions 21b and the plurality of second stage portions 31b, at least one second stage portion 31b is arranged vertically with at least one first stage portion 21b. It is sufficient to provide a portion that does not overlap.

A handrail 22 is provided on the first adjacent portion 21 at the position of the partition line L1. Furthermore, the second adjacent portion 31 is provided with a handrail 32 at the position of the partition line L3. The handrails 22 and 32 include visibility members, such as glass or a plurality of crosspieces. Therefore, the handrails 22 and 32 are configured to be visible. Therefore, a person on the predetermined standard floor 10 can visually recognize the liveliness of the first adjacent portion 21 and the second adjacent portion 31 through the handrails 22 and 32 . This makes it easier for people on the base hierarchy 10 to be more interested in the first upper hierarchy 20 and the second upper hierarchy 30 . As a result, the effect of attracting more people to the upper floor can be expected.

Glass walls or the like may be placed at the positions of the partition lines L1 and L3. , and the atrium space 40 are preferably communicated with each other. By doing so, the unity of the first adjacent portion 21 and the second adjacent portion 31 and the atrium space 40 can be emphasized, and the effect of attracting people to the upper floors can be expected.

Further, as shown in FIG. 2, the width W1 of the first adjacent portion 21 is wider than the surroundings at the position of the first stage portion 21b. More specifically, the width W1 of the first adjacent portion 21 in the passage width direction A orthogonal to the reference line L2 in plan view varies along the atrium 40, and is wider at the position of the first stage portion 21b than the surroundings. It is wide.

Furthermore, as shown in FIG. 3, the width W2 of the second adjacent portion 31 is wider than the surroundings at the position of the second stage portion 31b. More specifically, the width W2 of the second adjacent portion 31 in the passage width direction A orthogonal to the reference line L4 in plan view varies along the atrium 40, and is wider at the position of the second stage portion 31b than the surroundings. It is wide.

FIG. 4 is a front view of the escalator as the lifting section 51 that connects the first upper story 20 and the second upper story 30 as seen from the atrium 40 side. As shown in FIGS. 2 to 4, the escalator as the lifting section 51 is provided at a position connecting the first stage section 21b and the second stage section 31b. More specifically, the lower portion of the escalator as the lifting section 51 is connected to the first stage section 21 b of the first adjacent section 21 of the first upper story 20 . Also, the upper part of the escalator as the lifting part 51 is connected to the second stage part 31 b of the second adjacent part 31 of the second upper floor 30 . Therefore, a person can go back and forth between the first stage portion 21b of the first upper story 20 and the second stage portion 31b of the second upper story 30 by the escalator as the lifting portion 51 shown in FIGS. be. In this way, by installing the lifting section 51 so as to connect the first stage section 21b and the second stage section 31b, a person on the standard floor 10 can be interested in the first upper floor 20 and the second upper floor 30 as well as , the first upper hierarchy 20 and the second upper hierarchy 30 can be recognized. Therefore, the effect of inviting more people to the upper floor can be expected.

Further, as shown in FIGS. 1 and 2, the predetermined standard floor 10 and the first upper floor 20 are connected by an escalator as a separate lifting section 51 . Further, there may be another lifting section 51 that connects the predetermined reference floor 10 and the second upper floor 30 .

The lifting unit 51 is not limited to the escalator of this embodiment. The ascending/descending part 51 may be stairs, an elevator, or the like. However, by constructing the lifting section 51 with an escalator, it is possible to improve the number of people that can be transported per unit time, which is the transportation efficiency between floors.

Next, further details of the first adjacent portion 21 and the second adjacent portion 31 in the building 100 will be described.

As described above, in the present embodiment, the second stage portion 31b has a portion that does not overlap the first stage portion 21b in the vertical direction. More specifically, the second stage portion 31b of the present embodiment includes a portion that does not vertically overlap the first stage portion 21b in a front view (see FIG. 4) seen from the atrium space 40 side. In other words, when viewed from the front (see FIG. 4), the second stage portion 31b of the present embodiment does not match the width of the first stage portion 21b in the horizontal direction and/or does not match the width of the first stage portion 21b. The center positions in the left and right directions are different. By doing so, a person on the predetermined reference floor 10 can see the positions of the first stage portion 21b of the first adjacent portion 21 and the second stage portion 31b of the second adjacent portion 31 in plan view, It is easy to recognize the difference in shape and the like. Therefore, people on the predetermined base hierarchy 10 are likely to be interested in the first upper hierarchy 20 and the second upper hierarchy 30 . This can be expected to have the effect of inviting people on the standard floor 10 to a higher floor.

Furthermore, the second stage portion 31b may protrude toward the atrium space 40 more than the first stage portion 21b. FIG. 5 is a diagram showing how the second stage portion 31b protrudes toward the atrium space 40 side more than the first stage portion 21b. As shown in FIG. 5, by projecting the second stage portion 31b of the second upper story 30 toward the atrium space 40 side more than the first stage portion 21b of the first upper story 20, the user is on the predetermined reference story 10. Humans tend to recognize differences in the positions, shapes, etc., in plan view between the first stage portion 21b of the first adjacent portion 21 and the second stage portion 31b of the second adjacent portion 31 . Therefore, people on the predetermined base hierarchy 10 are likely to be interested in the first upper hierarchy 20 and the second upper hierarchy 30 . This can be expected to have the effect of inviting people on the standard floor 10 to a higher floor.

The second stage portion 31b has a portion that does not overlap the first stage portion 21b in the vertical direction in a front view (see FIG. 4) viewed from the atrium space 40 side, and the atrium space is located closer to the atrium space than the first stage portion 21b. It may protrude towards 40.

Furthermore, as shown in FIGS. 2 to 4, each of the first stage portion 21b and the second stage portion 31b of this embodiment includes a lower slab member 61 and an upper slab member 62. As shown in FIG. At least a part of the upper slab material 62 is laminated on the lower slab material 61 in the vertical direction.

In this embodiment, each of the first stage portion 21b and the second stage portion 31b includes the lower slab member 61 and the upper slab member 62, but the configuration is not limited to this. Only one of the first stage portion 21 b and the second stage portion 31 b may be configured to include the lower slab member 61 and the upper slab member 62 .

In addition, the first adjacent portion 21 of the present embodiment is cantilevered on the atrium space 40 side from a plurality of pillars 25 arranged along the reference line L2. Therefore, as shown in FIG. 5, the slab that constitutes the first adjacent portion 21 is configured so that the thickness decreases from the reference line L2 toward the atrium space 40. As shown in FIG. More specifically, in the first adjacent portion 21 of the present embodiment, the first stage portion 21b has a two-layer structure of the lower slab member 61 and the upper slab member 62, and the first passage portion 21a includes the lower slab member 61 and the upper slab member 62. It has a three-layer structure including the slab material 62 and another slab material. The second adjacent portion 31 of this embodiment also has the same structure. However, the laminated structure of the slab materials of the first adjacent portion 21 and the second adjacent portion 31 is not limited to the structure of the present embodiment. The passage portion may be formed by laminating four or more layers of slab materials.

Further, the lower slab member 61 and the upper slab member 62 forming the first stage portion 21b and the second stage portion 31b, respectively, may completely coincide in horizontal position and completely overlap in the vertical direction. However, as in this embodiment, the lower slab member 61 and the upper slab member 62 that respectively constitute the first stage portion 21b and the second stage portion 31b preferably have portions that do not overlap in the vertical direction. In this way, the floor thickness of each of the first stage portion 21b and the second stage portion 31b can be adjusted depending on the position. Therefore, compared with the first stage portion and the second stage portion having a uniform thickness, it becomes easier to emphasize the specificity of each of the first stage portion 21b and the second stage portion 31b.

In the present embodiment, the lower slab material 61 and the upper slab material 62 that respectively constitute the first stage portion 21b and the second stage portion 31b are vertically Provide non-overlapping parts. Furthermore, the upper slab member 62 may protrude toward the atrium space 40 more than the lower slab member 61 . In this way, the positions of the portions where the lower slab member 61 and the upper slab member 62 that constitute the first stage portion 21b and the second stage portion 31b do not overlap are not particularly limited.

The portion where the lower slab member 61 and the upper slab member 62 constituting the first stage portion 21b and the second stage portion 31b do not overlap in the vertical direction may be designed according to the application of the position, for example. In each of the first stage portion 21b and the second stage portion 31b, for example, the position where the escalator as the lifting portion 51 is connected may be the position where the lower slab member 61 and the upper slab member 62 overlap in the vertical direction. In this way, the thickness of the floor of the portion supporting the lifting section 51 to which a vertical load is likely to be applied can be increased. On the other hand, the lower slab member 61 and the upper slab member 61 and the upper slab member 61 and the upper slab member 61 are placed at positions where the lifting unit 51 and people are not directly supported from below, such as positions used only for placing decorative materials such as flowers. The position may be such that the members 62 do not overlap in the vertical direction. For example, the lower slab member 61 may be made to protrude from the upper slab member 62 in the lateral direction in front view (see FIG. 4) or toward the atrium 40 side, and the upper surface of the protruding portion of the lower slab member 61 may be covered with plants, flowers, or trees. A decorative material such as . In this manner, the degree of overlapping of the lower slab member 61 and the upper slab member 62 may be designed according to the use of each location of the first stage portion 21b and the second stage portion 31b.

Further, as shown in FIG. 5, it is preferable that a projecting portion 62a projecting toward the atrium space 40 is provided at the lower portion of the end surface of the upper slab member 62 on the atrium space 40 side. In other words, the upper part of the end face of the upper slab material 62 on the side of the atrium space 40 is preferably chamfered. By doing so, it becomes easier for a person on the predetermined reference floor 10 to visually recognize the liveliness of the first stage portion 21b and the second stage portion 31b. Also, the upper surface of the projecting portion 62a may be used as a space for arranging decorative materials such as plants and flowers.

For the same reason as described above, not only the upper slab material 62 but also the lower slab material 61 is preferably provided with a projecting portion at the lower portion of the end surface on the side of the atrium space 40 .

The building and design method according to the present invention are not limited to the configuration specifically shown in the above-described embodiment and the design method of the configuration, and various modifications and variations are possible without departing from the gist of the invention described in the scope of claims. Change is possible. Therefore, it is preferable to set the number of floors from the standard floor 10 to the second upper floor 30 so that the first upper floor 20 and the second upper floor 30 can be visually recognized from the standard floor 10 through the atrium space 40 . Depending on the floor area at the position of the atrium space 40 on the reference floor 10, for example, the number of floors is preferably 3 to 5 floors.
