[0013] [Figure 1] It is a plan view of a building as one embodiment of the present invention. [Figure 2] It is a view showing details near the middle column shown in FIG. 1. [Figure 3] It is a front view of the vicinity of the middle column shown in FIG. 1.

Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the middle column, the shutter structure, and the building according to the present invention will be illustrated and described with reference to the drawings. The same reference numerals are assigned to common members and parts in each figure.

[0015] FIG. 1 is a plan view of the second floor of a building 1000 as an embodiment of the building according to the present invention. In this embodiment, the building 1000 is a two-story building, but the building 1000 may be a single-story building or a three-story building or higher. FIG. 1 is a plan view of the second floor of the building 1000 of this embodiment, but the same floor plan as that of FIG. 1 may be adopted on another floor of the building 1000. The second floor of the building 1000 of this embodiment is an office, but its use is not particularly limited.

[0016] As shown in FIG. 1, the second floor of the building 1000 of this embodiment includes a first living room 1001 having the largest floor area on the second floor, and a plurality of second living rooms 1002 and a plurality of staircase rooms 1003 that are arranged adjacent to the first living room 1001 so as to be accessible to and from the first living room 1001 and have a smaller floor area than the first living room 1001. The plurality of second living rooms 1002 are arranged on both sides of the first living room 1001, one side and the other side, in plan view (see FIG. 1). Also, the plurality (two in this embodiment) of staircase rooms 1003 are also arranged on both sides of the first living room 1001, one side and the other side, in plan view (see FIG. 1). Hereinafter, for the sake of convenience of explanation, the direction in which the plurality of second living rooms 1002 and the plurality of staircase rooms 1003 are located with respect to the first living room 1001 in FIG. 1 is simply referred to as "vertical direction A", and the direction orthogonal to the vertical direction A in FIG. 1 is simply referred to as "horizontal direction B".

[0017] The first living room 1001 of this embodiment is partitioned by a partition wall 1004 that is located on both sides in the vertical direction A in plan view (see FIG. 1) and extends in the horizontal direction B, and outer walls 1005 that are located on both sides in the horizontal direction B. The partition wall 1004 is a partition wall that partitions between the first living room 1001 and the plurality of second living rooms 1002 and the plurality of staircase rooms 1003. The partition wall 1004 of this embodiment extends continuously in the horizontal direction B, but may be arranged intermittently. The outer wall 1005 is a partition wall that partitions between the first living room 1001 and the outdoor space. In addition to the plurality of staircase rooms 1003 described above, a staircase 1200 connected to the first floor of the building 1000 is provided in the first living room 1001 of this embodiment. Also, a stepped portion 1100 is formed in the floor portion 1001G of the first living room 1001 of this embodiment.

[0018] As shown in Figure 1, the first living room 1001 of the building 1000 in this embodiment is equipped with a shutter structure 200 that can partition the first living room 1001 into a first indoor space 1001A and a second indoor space 1001B. As shown in Figure 1, the shutter structure 200 in this embodiment is equipped with a plurality of shutters 210 that extend in the vertical direction A between partition walls 1004 on both sides in the vertical direction A. The shutter structure 200 is also equipped with a central column 100 that can connect two shutters 210 that are connected in the vertical direction A. The shutter structure 200 in this embodiment is equipped with three shutters 210 and two central columns 100. However, the number of shutters 210 is not particularly limited and may be, for example, two or four or more. The number of central columns 100 may also be appropriately changed according to the number of shutters 210.

[0019] As shown in Figure 1, the shutter 210 of the shutter structure 200 can partition the first room 1001 of the building 1000 into a first indoor space 1001A located on one side in the left-right direction B relative to the shutter 210, and a second indoor space 1001B located on the other side in the left-right direction B relative to the shutter 210. Hereinafter, the state in which the first room 1001 is partitioned into the first indoor space 1001A and the second indoor space 1001B by the multiple shutters 210 of the shutter structure 200 will be described as the "partitioned state". The state in which the first room 1001 is not partitioned into the first indoor space 1001A and the second indoor space 1001B by the multiple shutters 210 of the shutter structure 200 will be described as the "connected state". Even in the connected state, the part that becomes the first indoor space 1001A in the partitioned state will be called the first indoor space 1001A. Furthermore, even when the spaces are connected, the portion that becomes the second indoor space 1001B when partitioned off is also referred to as the second indoor space 1001B.

[0020] The shutter 210 may be provided with one or more (one or two in this embodiment) entrances / exits 210D that allow passage in the left-right direction B when it is in a partitioned state. The shutter 210 in this embodiment is a sheet shutter, and the entrances / exits 210D may be formed by slits formed in the sheet shutter.

[0021] The sheet shutter used as shutter 210 may be, for example, a fire-resistant shutter. When a fire-resistant shutter is constructed using a sheet shutter as shutter 210, shutter 210 may be made of, for example, silica cloth. A base plate may be attached to the lower end of shutter 210 that abuts against the floor portion 1001G of the first room 1001. Note that shutter 210 is not limited to a sheet shutter. Shutters 210 may also be heavy-duty shutters.

[0022] Each of the exterior walls 1005 located on both sides in the left-right direction B of the first living room 1001 of the building 1000 is provided with a viewing section 1005A that allows visibility into the outdoor space from the first living room 1001. The configuration of the viewing section 1005A is not particularly limited, as long as it allows visibility into the outdoor space from the first living room 1001. The viewing section 1005A may be made of a transparent member such as a glass plate provided in the opening of the exterior wall 1005. This transparent member may be included in a fitting that can open and close the opening of the exterior wall 1005, or it may be fixed in the opening of the exterior wall 1005. Alternatively, the viewing section 1005A may be the curtain wall itself, which is the exterior wall 1005, made of a transparent member such as a glass plate.

[0023] In the building 1000 of this embodiment, a user using the first living room 1001 can see the sight-through sections 1005A on both sides in the left-right direction B while in a state of communication. In other words, a user in the first indoor space 1001A of the first living room 1001 can see the sight-through section 1005A provided in the outer wall 1005 (the right outer wall 1005 in Figure 1) that separates the second indoor space 1001B from the outdoor space, through the opening between the partition wall 1004 and the central column 100, and the openings between the multiple central columns 100. Furthermore, a user in the second indoor space 1001B of the first living room 1001 can, in a connected state, view the viewing section 1005A provided in the outer wall 1005 (the left outer wall 1005 in Figure 1) that separates the first indoor space 1001A from the outdoor space, through the opening between the partition wall 1004 and the central column 100, and the openings between the multiple central columns 100.

[0024] Thus, the first living room 1001 of the building 100 in this embodiment is configured such that, in a connected state, a user located in one of the first indoor space 1001A and the second indoor space 1001B can see the viewing section 1005A, which is an object installed in the other of the first indoor space 1001A and the second indoor space 1001B. The object is not limited to the viewing section 1005A provided on the exterior wall 1005 in this embodiment, but may be, for example, a work of art such as a painting, a screen or interior wall surface for image projection, a stage, etc. The object does not have to be located on or near the exterior wall 1005, but may be located, for example, in the central part of the first indoor space 1001A or the second indoor space 1001B.

[0025] As described above, a step portion 1100 is formed in the floor portion 1001G of the first living room 1001 in this embodiment. The floor portion 1001G of the first living room 1001 is divided into a first floor portion 1001G1, which is lower in height, and a second floor portion 1001G2, which is higher in height, with the step portion 1100 as the boundary. In this way, by providing a step portion 1100 in the floor portion 1001G of the first living room 1001, the spaces on both sides of the step portion 1100 as a boundary are connected without being partitioned, and a large open space can be realized. On the other hand, the step portion 1100 is easily recognized as a boundary, making it easy to separate and use the spaces on both sides of the step portion 1100 as a boundary. As shown in Figure 1, the stepped section 1100 in this embodiment is provided with alternating parallel sections 1100A1 that extend substantially parallel to the extending direction of the outer wall 1005 in a plan view, and inclined sections 1100B1 that extend in a direction intersecting the extending direction of the outer wall 1005 in a plan view. The stepped section 1100 may be used as a seat, for example. Therefore, a rest area where the stepped section 1100 can be used as a seat may be provided at the location of the stepped section 1100. Note that the stepped section 1100 may consist of only one stepped surface (for example, only the parallel section) connecting the first floor section 1001G1 and the second floor section 1001G2, or it may be a staircase-like configuration having multiple stepped surfaces, as in this embodiment.

[0026] As shown in Figure 1, the multiple shutters 210 of the shutter structure 200 may be arranged in a plan view along the stepped portion 1100.

[0027] As shown in Figure 1, the multiple shutters 210 of the shutter structure 200 in this embodiment are located at the lower height of the first floor section 1001G1 of the floor section 1001G of the first living room 1001, but the configuration is not limited to this. The multiple shutters 210 of the shutter structure 200 may, for example, be located at the higher height of the second floor section 1001G2 of the floor section 1001G of the first living room 1001. Also, as shown in Figure 1, the stairs 1200 in this embodiment are provided at the second floor section 1001G2, but the configuration is not limited to this. The stairs 1200 may be provided at the first floor section 1001G1.

[0028] Next, with reference to Figures 2 and 3, the configuration of the vicinity of one central column 100 of the shutter structure 200 will be described in detail. Figure 2 is a detailed view of the vicinity of the upper central column 100 of the two central columns 100 shown in Figure 1. Figure 3 is a front view of the vicinity of the upper central column 100 of the two central columns 100 shown in Figure 1, viewed from left to right. For the sake of explanation, the two shutters 210 connected by one central column 100 will be referred to as "first shutter 210A" and "second shutter 210B". Also, when there is no particular distinction between "first shutter 210A" and "second shutter 210B", they will simply be referred to as "shutter 210". Note that here, only the vicinity of the upper central column 100 of the two central columns 100 shown in Figure 1 will be described, but the configuration of the vicinity of the lower central column 100 of the two central columns 100 shown in Figure 1 is the same.

[0029] As shown in Figures 2 and 3, the shutter structure 200 comprises a central column 100, a first shutter 210A and a second shutter 210B connected by the central column 100, a first shutter box 220A, and a second shutter box 220B. As shown in Figure 3, the first shutter box 220A of this embodiment houses a first shaft 230A and a first drive unit 240A. Also, as shown in Figure 3, the second shutter box 220B of this embodiment houses a second shaft 230B and a second drive unit 240B. In Figure 2, for the sake of explanation, the positions of the first shutter box 220A and the second shutter box 220B, as well as the positions of the first drive unit 240A and the second drive unit 240B, are shown by dashed lines. In Figure 3, since the positions of the first drive unit 240A and the second drive unit 240B partially overlap, their positions are shown by the same dashed rectangles.

[0030] As described above, the first shutter 210A and the second shutter 210B can be connected by the central column 100. In this embodiment, the central column 100 is erected vertically d3 from the floor portion 1001G of the first living room 1001. More specifically, in this embodiment, the central column 100 is erected vertically d3 from the first floor portion 1001G1 of the floor portion 1001G of the first living room 1001. The base of the central column 100 is fixed to the floor portion 1001G. The top of the central column 100 is fixed to the ceiling portion of the first living room 1001. The central column 100 may be formed by combining various steel materials such as square steel pipes, angle steel, and lip channel steel.

[0031] The central column 100 includes a first guide rail 110A capable of guiding the first shutter 210A vertically, and a second guide rail 110B capable of guiding the second shutter 210B vertically. The first guide rail 110A is provided on a first side surface 100S1 located on one side of the central column 100 in the width direction d1. The second guide rail 110B is provided on a second side surface 100S2 located on the other side of the central column 100 in the width direction d1. Here, "width direction d1 of the central column 100" is the direction along the first shutter 210A and the second shutter 210B connected by the central column 100 in a plan view (see Figures 1 and 2), and in this embodiment, it is the vertical direction A.

[0032] As shown in Figure 2, the first guide rail 110A of this embodiment includes a first slit portion 111A capable of receiving the widthwise end portion 210A1 of the first shutter 210A. The first slit portion 111A extends vertically in an elongated shape and opens to the first side surface 100S1. The first shutter 210A can move vertically while its end portion 210A1 is inserted into the first slit portion 111A of the first guide rail 110A. In other words, the first shutter 210A can move vertically because its end portion 210A1 is guided by the first slit portion 111A of the first guide rail 110A.

[0033] Furthermore, the second guide rail 110B of this embodiment includes a second slit portion 111B capable of receiving the widthwise end portion 210B1 of the second shutter 210B. The second slit portion 111B extends vertically in an elongated shape and opens to the second side surface 100S2. The second shutter 210B can move vertically while its end portion 210B1 is inserted into the second slit portion 111B of the second guide rail 110B. In other words, the second shutter 210B can move vertically because its end portion 210B1 is guided by the second slit portion 111B of the second guide rail 110B.

[0034] As shown in Figure 2, the first guide rail 110A and the second guide rail 110B are positioned at different locations in the depth direction d2 of the central column 110. The "depth direction d2 of the central column 100" is the direction perpendicular to the width direction d1 in a plan view (see Figures 1 and 2), and in this embodiment, it is the left-right direction B. This makes it difficult for the first guide rail 110A and the second guide rail 110B to interfere with each other. Also, it makes it difficult for the first shutter box 220A and the second shutter box 220B to interfere above the central column 100. As a result, the length w in the width direction d1 of the central column 100 can be reduced. This suppresses the reduction in visibility along the depth direction d2 due to the presence of the central column 100. Specifically, in the first living room 1001 of the building 1000 of this embodiment, when in a connected state, the reduction in visibility from one of the first indoor space 1001A and the second indoor space 1001B to the other due to the central column 100 can be suppressed. Therefore, in this embodiment, the visible portion 1005A, which is an object installed in the first indoor space 1001A, becomes easier to see from the second indoor space 1001B while in a state of communication. Also, in this embodiment, the visible portion 1005A, which is an object installed in the second indoor space 1001B, becomes easier to see from the first indoor space 1001A while in a state of communication.

[0035] Furthermore, if the widths of the first shutter 210A and the second shutter 210B are different, the length of the guide rail in the width direction d1 that receives the end of the wider shutter (the second shutter 210B in this embodiment) may be made longer than the length of the guide rail in the width direction d1 that receives the end of the narrower shutter (the first shutter 210A in this embodiment). By doing so, deformation of the wider shutter, which is more prone to deformation in the thickness direction, can be suppressed.

[0036] Furthermore, the central column 100 of this embodiment includes a substantially rectangular outer frame 120. A first guide rail 110A is attached to one side wall of the outer frame 120 in the width direction d1. A second guide rail 110B is attached to the other side wall of the outer frame 120 in the width direction d1. The first side surface 100S1 of the central column 100 of this embodiment is composed of the one side wall of the outer frame 120 in the width direction d1 and the first guide rail 110A. The second side surface 100S2 of the central column 100 of this embodiment is composed of the other side wall of the outer frame 120 in the width direction d1 and the second guide rail 110B. The constituent material of the outer frame 120 is not particularly limited, but may be, for example, steel. Note that a base material 130 to which the outer frame 120 is attached may be provided inside the outer frame 120.

[0037] As shown in Figure 2, in this embodiment, the length l in the depth direction of the central column 100 is longer than the length w in the width direction of the central column 100. The length l in the depth direction of the central column 100 is, for example, about 600 mm. The length w in the width direction of the central column 100 is, for example, about 150 mm.

[0038] Furthermore, as shown in Figures 2 and 3, in this embodiment, the first shutter box 220A and the second shutter box 220B are arranged above the central column 100 in the vertical direction d3, overlapping in the depth direction d2. In other words, the first shutter box 220A and the second shutter box 220B are positioned directly above the central column 100, partially overlapping (duplication) in the width direction d1. Also, as shown in Figure 2, the first shutter box 220A and the second shutter box 220B are arranged spaced apart in the depth direction d2. Thus, in the shutter structure 200 of this embodiment, the first shutter box 220A and the second shutter box 220B can be arranged above the central column 100 in the vertical direction d3 without interfering with each other.

[0039] The first shutter box 220A is capable of housing the first shutter 210A. More specifically, as shown in Figure 3, the first shutter box 220A houses the first shaft 230A and the first drive unit 240A.

[0040] The first shaft 230A is capable of winding around the first shutter 210A. The first shaft 230A extends above the central column 100 along the width direction d1. The first shaft 230A is cylindrical.

[0041] The first drive unit 240A is capable of winding the first shutter 210A onto the first shaft 230A. The first drive unit 240A can rotationally drive the first shaft 230A. By rotating the first shaft 240A, the first shutter 210A can be wound up and unwound. In other words, by rotating the first shaft 240A, the first shutter 210A can be raised and lowered. The first drive unit 240A may be, for example, an electric motor.

[0042] The second shutter box 220B is capable of housing the second shutter 210B. More specifically, as shown in Figure 3, the second shutter box 220B houses the second shaft 230B and the second drive unit 240B.

[0043] The second shaft 230B can be wrapped around the second shutter 210B. The second shaft 230B extends above the central column 100 along the width direction d1. The second shaft 230B is cylindrical.

[0044] The second drive unit 240B is capable of winding the second shutter 210B onto the second shaft 230B. The second drive unit 240B can rotationally drive the second shaft 230B. By rotating the second shaft 240B, the second shutter 210B can be wound up and unwound. In other words, by rotating the second shaft 240B, the second shutter 210B can be raised and lowered. The second drive unit 240B may be, for example, an electric motor.

[0045] As described above, in this embodiment, the first shutter box 220A and the second shutter box 220B are arranged above the central column 100 in the vertical direction d3, partially overlapping in the depth direction d2. More specifically, in this embodiment, as shown in Figures 2 and 3, the first drive unit 240A housed in the first shutter box 220A and the second drive unit 240B housed in the second shutter box 220B are arranged above the central column 100 in the vertical direction d3, partially overlapping in the depth direction d2. In other words, in the shutter structure 200 of this embodiment, the first drive unit 240A and the second drive unit 240B are arranged directly above the central column 100, spaced apart in the depth direction d2.

[0046] The central column, shutter structure, and building according to the present invention are not limited to the specific configurations and processes shown in the embodiments described above, and various modifications and changes are possible as long as they do not depart from the scope of the claims.
