Description

[Technical field]

[0001] The technology disclosed in this specification relates to buildings. [Background technology]

[0002] In a building, a shaft, which is a space extending in the vertical direction, may be formed. More specifically, for example, when a plurality of rooms are formed, including a certain room (first room) and another room (second room) horizontally adjacent to the first room, and each room is divided into an upper floor and a lower floor, the shaft is formed between the first room and the second room so as to extend in the vertical direction across the upper floor and the lower floor.

[0003] There are various kinds of shafts. Examples of shafts include an elevator shaft that functions as an elevator shaft in a building, and a return shaft that functions as a circulation flow path for circulating clean air supplied from the space above the ceiling to a clean room, which is an example of a building, back to the space above the ceiling.

[0004] 2. Description of the Related Art Conventionally, buildings in which beams are provided inside an elevator shaft have been disclosed (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2009-84049 A Summary of the Invention [Problem to be solved by the invention]

[0006] When beams are installed within a shaft as in the above-mentioned building, it is necessary to secure space within the shaft to install the beams, which may increase the area occupied by the shaft and ultimately reduce the area occupied by the room.

[0007] This specification discloses a technique that can solve the above-mentioned problems. [Means for solving the problem]

[0008] The technology disclosed in this specification can be realized, for example, in the following forms.

[0009] (1) The building disclosed in this specification is formed with a plurality of rooms and a shaft. The plurality of rooms include a first room and a second room horizontally adjacent to the first room, and each of the rooms is divided into an upper layer and a lower layer. The shaft is a space extending vertically between the first room and the second room, straddling the upper layer and the lower layer. The building includes a first side wall, a second side wall, a first beam, and a second beam. The first side wall divides the first room and the shaft. The second side wall divides the second room and the shaft. The first beam is a beam that constitutes a floor structure of the upper layer of the first room, extends approximately parallel to the first side wall, and is disposed closest to the second room. The second beam is a beam constituting the upper floor structure of the second room, extends approximately parallel to the second side wall, and is disposed closest to the first room. The shaft is located between the first beam and the second beam.

[0010] According to this building, the shaft is located between the first beam and the second beam. In other words, in this building, no beam is arranged in the shaft. Therefore, compared to a configuration in which a beam is arranged in the shaft, for example, there is no need to secure space to install a beam in the shaft, so the area occupied by the shaft can be reduced, and the area occupied by the room can be expanded.

[0011] (2) In the above-mentioned building, the first beam may be arranged to be aligned vertically with the first side wall, and the second beam may be arranged to be aligned vertically with the second side wall. According to this configuration, the first beam is arranged to be aligned vertically with the first side wall, and the second beam is arranged to be aligned vertically with the second side wall. That is, in this configuration, no beam is arranged in the shaft. Therefore, compared to a configuration in which a beam is arranged in the shaft, for example, there is no need to secure space for installing a beam in the shaft, so the area occupied by the shaft can be reduced, and the area occupied by the room can be expanded more effectively.

[0012] (3) In the above-mentioned building, the first side wall may include a first partition plate located above the first beam and a second partition plate located below the first beam, and the first beam may be connected to each of the first partition plate and the second partition plate. According to this configuration, since each of the first partition plate and the second partition plate is connected to the first beam, the first side wall can be easily fixed to the installation location.

[0013] (4) The above-mentioned building may further include a stiffener plate that joins the first beam and the second beam. According to this configuration, the first beam and the second beam are joined by the stiffener plate, so that buckling of the first beam and the second beam can be suppressed and the strength of the building can be improved.

[0014] (5) In the above-mentioned building, the building may be a clean room, the room may be a clean room, and the shaft may be a return shaft. With this configuration, compared to a configuration in which a beam is disposed in a return shaft in a clean room, for example, there is no need to secure space for installing a beam in the return shaft, so the area occupied by the return shaft can be reduced, and the area occupied by the clean room can be expanded.

[0015] The technology disclosed in this specification can be realized in various forms, for example, in the form of a building, a construction method for a building, etc. [Brief description of the drawings]

[0016] [Figure 1] FIG. 1 is an explanatory diagram showing the overall structure of a building 10. [Diagram 2] FIG. 1 is an explanatory diagram showing the configuration around the shaft 40. [Diagram 3] FIG. 1 is an explanatory diagram showing the configuration around the shaft 40. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] A. Embodiment: A-1. Building 10 composition: FIG. 1 is an explanatory diagram that shows a schematic overall configuration of a building 10. In FIG. 1 and each of the following figures, mutually orthogonal XYZ axes for specifying directions are shown. FIG. 1 shows the XZ cross-sectional configuration of the building 10. In this specification, the X-axis direction and the Y-axis direction are parallel to the horizontal direction, and the Z-axis direction is parallel to the up-down (vertical) direction (the positive Z-axis direction is the upward direction, and the negative Z-axis direction is the downward direction). Note that the X-axis direction and the Y-axis direction do not need to be strictly parallel to the horizontal direction, and may have a certain inclination with respect to the horizontal direction. Similarly, the Z-axis direction does not need to be strictly parallel to the up-down direction, and may have a certain inclination with respect to the up-down direction.

[0018] In this embodiment, the building 10 is, for example, a clean room. More specifically, the building 10 is a building equipped with a clean room in which air cleanliness is ensured, and is used, for example, as a manufacturing factory for semiconductors or precision machinery. The building 10 includes a plurality of rooms 20, an upper space 30, and a shaft 40.

[0019] The multiple rooms 20 are living spaces in the building 10. The multiple rooms 20 are composed of multiple rooms including a first room 20A and a second room 20B horizontally adjacent to the first room 20A. Each room 20 is divided into an upper layer 21 and a lower layer 22 located below the upper layer 21. The upper layer 21 and the lower layer 22 communicate with each other via a gap formed in a floor structure 400 described later.

[0020] In this embodiment, the room 20 is, for example, a clean room. More specifically, the room 20 is a space in which air cleanliness is ensured by supplying clean air in which fine particles such as dust and microorganisms are reduced. In addition, in this embodiment, the upper layer 21 is, for example, a manufacturing area, and the lower layer 22 is, for example, a sub-fab. More specifically, the upper layer 21 is a work space in which, for example, semiconductors and precision machinery are manufactured. Since air cleanliness is ensured in the room 20, the risk of foreign matter being mixed into various products manufactured in the upper layer 21 is reduced. In the lower layer 22, for example, auxiliary equipment (for example, a chiller, a vacuum pump, etc.) required for manufacturing semiconductors and the like in the upper layer 21 is installed.

[0021] The upper space 30 is a space above the ceiling of the multiple rooms 20, and is located above the multiple rooms 20. The upper space 30 communicates with the multiple rooms 20 via a fan filter unit 100 described later.

[0022] The shaft 40 is a space located between the first room 20A and the second room 20B. The shaft 40 extends in the vertical direction across the upper floor 21 and the lower floor 22. In other words, the shaft 40 is a space that penetrates the building 10 in the vertical direction. The upper floor 21 and the shaft 40 communicate with each other via a vent (not shown) provided in the side wall 200 described later. The lower floor 22 and the shaft 40 communicate with each other via a vent (not shown) provided in the side wall 200 described later. The upper space 30 and the shaft 40 communicate with each other. That is, the shaft 40 is in communication with each of the upper layer 21, the lower layer 22, and the upper space 30.

[0023] In this embodiment, the shaft 40 is a return shaft. More specifically, the shaft 40 functions as a circulation flow path that circulates the clean air supplied from the upper space 30 to the room 20 back to the upper space 30.

[0024] The building 10 also includes a fan filter unit 100, a plurality of side walls 200, pillar members 300, and a floor structure 400.

[0025] The fan filter unit 100 is attached to a plate material that separates the upper layer 21 and the upper space 30. The fan filter unit 100 has a filter 110 and a fan 120. The filter 110 is a member with fine holes formed therein, and it collects dust and microorganisms in the air, and supplies and exhausts air between the upper space 30 and the upper layer 21. The filter 110 is, for example, a HEPA filter (High Efficiency Penetration Air Filter) or a ULPA filter (Ultra Low Penetration Air Filter). The fan 120 has multiple blades and generates an air flow F within the building 10.

[0026] The side walls 200 are plate members arranged vertically in the X-axis direction, and partition the room 20 and the shaft 40. The side walls 200 are provided with an air vent (not shown) relatively below the portion that partitions the upper layer 21 and the shaft 40, allowing the upper layer 21 and the shaft 40 to communicate with each other. The side walls 200 are also provided with an air vent (not shown) relatively below the portion that partitions the lower layer 22 and the shaft 40, allowing the lower layer 22 and the shaft 40 to communicate with each other. The side walls 200 include a first side wall 200A and a second side wall 200B. The first side wall 200A partitions the first room 20A and the shaft 40. The second side wall 200B partitions the second room 20B and the shaft 40.

[0027] The pillar 300 is a member extending in the vertical direction (Z-axis direction) (see FIG. 3). In this embodiment, the pillar 300 separates the outside of the building 10 from the shaft 40. The pillar 300 supports a first beam 410A and a second beam 410B, which will be described later.

[0028] The floor structure 400 constitutes the floor surface of the upper level 21 and the ceiling surface of the lower level 22. The floor structure 400 has a plurality of beams 410, joists 420, and a grating 430.

[0029] The beams 410 are members extending in the horizontal direction (Y-axis direction). The beams 410 are arranged at intervals in the X-axis direction, so that there is a gap between two adjacent beams 410. The beams 410 are located below the joists 420 and support the joists 420. The beams 410 include a first beam 410A and a second beam 410B. The first beam 410A is a beam that constitutes the floor structure 400 of the upper level 21 of the first room 20A, extends approximately parallel to the first side wall 200A (Y-axis direction), and is disposed closest to the second room 20B. The second beam 410B is a beam that constitutes the floor structure 400 of the upper level 21 of the second room 20B, extends approximately parallel to the second side wall 200B (Y-axis direction), and is positioned closest to the first room 20A.

[0030] The joists 420 are members extending horizontally (in the X-axis direction). The multiple joists 420 are arranged at intervals in the Y-axis direction, so that there is a gap between two adjacent joists 420. The joists 420 are located below the grating 430 and support the grating 430.

[0031] Grating 430 is made of, for example, metal, and is a lattice-like member having a plurality of holes (not shown) penetrating in the Z-axis direction.

[0032] As described above, there are gaps between the beams 410 that make up the floor structure 400 and between the joists 420 that make up the floor structure 400, and there are multiple holes in the grating 430 that makes up the floor structure 400. Therefore, gaps that communicate in the vertical direction are formed in the floor structure 400. Because of this configuration, the floor structure 400 divides the upper layer 21 and the lower layer 22 so that they can communicate with each other.

[0033] The air flow F in the building 10 will be described in detail with reference to FIG. 1. The air inside the building 10 circulates by leaving the upper space 30 and passing through the room 20 and the shaft 40. Specifically, the air inside the building 10 is first supplied from the upper space 30 to the upper floor 21 through the fan filter unit 100. At this time, the air passes through the filter 110, so that dust, microorganisms, etc. in the air are captured by the filter 110. Next, the air supplied to the upper floor 21 flows directly from the upper floor 21 to the shaft 40, or passes from the upper floor 21 to the lower floor 22 and flows into the shaft 40. Next, the air that flows into the shaft 40 flows into the upper space 30. As a result, the air that has passed through the filter 110 is supplied to the room 20, so that the cleanliness inside the room 20 is maintained. In this way, the building 10 of this embodiment employs a vertical unidirectional laminar flow method (downflow method) in which clean air flows from above to below.

[0034] A-2. Detailed configuration around shaft 40: Next, a detailed configuration of the periphery of the shaft 40 in the building 10 of this embodiment will be described. Figures 2 and 3 are explanatory diagrams showing the configuration of the periphery of the shaft 40. Figure 2 shows an enlarged XZ cross-sectional configuration of the building 10 at part X1 in Figure 1. Also, Figure 3 shows an XY cross-sectional configuration of the building 10 at the position III-III in Figure 2.

[0035] As shown in FIG. 2, the shaft 40 is located between the first beam 410A and the second beam 410B. The first beam 410A is arranged so as to be aligned with the first side wall 200A in the vertical direction. The first beam 410A, together with the first side wall 200A, divides the first room 20A and the shaft 40. The second beam 410B is arranged so as to be aligned with the second side wall 200B in the vertical direction. The second beam 410B, together with the second side wall 200B, divides the second room 20B and the shaft 40. That is, no beam 410 is arranged in the shaft 40.

[0036] The first side wall 200A includes a first partition plate 210A and a second partition plate 220A. The first partition plate 210A is located above the first beam 410A and separates the upper layer 21 from the upper portion of the shaft 40. The second partition plate 220A is located below the first beam 410A and separates the lower layer 22 from the lower portion of the shaft 40. The upper end of the first beam 410A is connected to the lower end of the first beam 210A, and the lower end of the first beam 410A is connected to the upper end of the second partition plate 220A. That is, the first beam 410A is connected to each of the first partition plate 210A and the second partition plate 220A.

[0037] The second side wall 200B includes a third partition plate 210B and a fourth partition plate 220B. The third partition plate 210B is located above the second beam member 410B and separates the upper layer 21 from the upper portion of the shaft 40. The fourth partition plate 220B is located below the second beam member 410B and separates the lower layer 22 from the lower portion of the shaft 40. The upper end of the second beam member 410B is connected to the lower end of the third partition plate 210B, and the lower end of the second beam member 410B is connected to the upper end of the fourth partition plate 220B. That is, the second beam member 410B is connected to each of the third partition plate 210B and the fourth partition plate 220B.

[0038] 3, the building 10 further includes a stiffener plate 500. The stiffener plate 500 is a plate-shaped member. The stiffener plate 500 is disposed vertically in the Y-axis direction, and joins the first beam 410A and the second beam 410B.

[0039] A-3. Advantages of this embodiment: As described above, the building 10 of this embodiment is formed with a plurality of rooms 20 and a shaft 40. The plurality of rooms 20 include a first room 20A and a second room 20B horizontally adjacent to the first room 20A, and each room 20 is divided into an upper layer 21 and a lower layer 22. The shaft 40 is a space extending in the vertical direction between the first room 20A and the second room 20B, straddling the upper layer 21 and the lower layer 22. The building 10 includes a first side wall 200A, a second side wall 200B, a first beam 410A, and a second beam 410B. The first side wall 200A partitions the first room 20A and the shaft 40. The second side wall 200B partitions the second room 20B and the shaft 40. The first beam 410A is a beam constituting the floor structure 400 of the upper level 21 of the first room 20A, extends approximately parallel to the first side wall 200A, and is disposed closest to the second room 20B. The second beam 410B is a beam constituting the floor structure 400 of the upper level 21 of the second room 20B, extends approximately parallel to the second side wall 200B, and is disposed closest to the first room 20A. The shaft 40 is located between the first beam 410A and the second beam 410B.

[0040] According to the building 10 of this embodiment, the shaft 40 is located between the first beam 410A and the second beam 410B. That is, the building 10 does not have the beam 410 arranged inside the shaft 40. Therefore, compared to a configuration in which a beam is arranged inside the shaft, for example, there is no need to secure space for installing the beam 410 inside the shaft 40, so the area occupied by the shaft 40 can be reduced, and the area occupied by the room 20 can be expanded.

[0041] In addition, in the building 10 of this embodiment, the first beam 410A is arranged so as to be aligned with the first side wall 200A in the vertical direction, and the second beam 410B is arranged so as to be aligned with the second side wall 200B in the vertical direction. According to the building 10 of this embodiment, the first beam 410A is arranged so as to be aligned with the first side wall 200A in the vertical direction, and the second beam 410B is arranged so as to be aligned with the second side wall 200B in the vertical direction. That is, in the building 10, the beam 410 is not arranged in the shaft 40. Therefore, compared to a configuration in which a beam is arranged in the shaft, for example, there is no need to secure a space for installing the beam 410 in the shaft 40, so the exclusive area of ​​the shaft 40 can be reduced, and thus the exclusive area of ​​the room 20 can be expanded more effectively.

[0042] In the building 10 of this embodiment, the first side wall 200A includes a first partition plate 210A located above the first beam 410A and a second partition plate 220A located below the first beam 410A, and the first beam 410A is connected to each of the first partition plate 210A and the second partition plate 220A. According to the building 10 of this embodiment, since each of the first partition plate 210A and the second partition plate 220A is connected to the first beam 410A, the first side wall 200A can be easily fixed to the installation location.

[0043] Moreover, the building 10 of this embodiment further includes a stiffener plate 500 that joins the first beam 410A and the second beam 410B. According to the building 10 of this embodiment, the first beam 410A and the second beam 410B are joined by the stiffener plate 500, so that buckling of the first beam 410A and the second beam 410B can be suppressed, and the strength of the building 10 can be improved.

[0044] In the building 10 of this embodiment, the building 10 is a clean room, the room 20 is a clean room, and the shaft 40 is a return shaft. In the building 10 of this embodiment, in a clean room, compared to a configuration in which a beam is arranged in a return shaft, for example, there is no need to secure space for installing the beam 410 in the return shaft, so the area occupied by the return shaft can be reduced, and the area occupied by the clean room can be expanded.

[0045] B. Variations: The technology disclosed in this specification is not limited to the above-described embodiments, and can be modified in various forms without departing from the spirit of the invention. For example, the following modifications are also possible.

[0046] The configuration of the building 10 in the above embodiment is merely an example, and various modifications are possible. For example, the shaft is not limited to two stories, the upper and lower stories, but may extend vertically across three or more stories.

[0047] In the above embodiment, the first beam 410A is arranged to be aligned vertically with the first side wall 200A, but the first beam does not necessarily have to be aligned vertically with the first side wall. Similarly, in the above embodiment, the second beam 410B is arranged to be aligned vertically with the second side wall 200B, but the second beam does not necessarily have to be aligned vertically with the second side wall.

[0048] In the above embodiment, the first side wall 200A includes the first partition plate 210A and the second partition plate 220A, but is not necessarily limited to such a configuration. Similarly, the second side wall 200B includes the third partition plate 210B and the fourth partition plate 220B, but is not necessarily limited to such a configuration.

[0049] Although the building 10 in the above embodiment is equipped with the stiffener plate 500, the building does not have to be equipped with a stiffener plate.

[0050] Although the pillar material 300 in the above embodiment separates the outside of the building 10 from the shaft 40, the pillar material does not have to separate the outside of the building from the shaft.

[0051] In the above embodiment, the building 10 is a clean room, but the present invention is not limited to this and can be applied to various buildings. Similarly, in the above embodiment, the room 20 is a clean room, the upper layer 21 is a manufacturing area, the lower layer 22 is a sub-fab, and the shaft 40 is a return shaft, but the uses of these spaces are not limited to the above embodiment.

[0052] Although the building 10 in the above embodiment is equipped with the fan filter unit 100, the building does not necessarily have to be equipped with a fan filter unit.

[0053] In the above embodiment, the upper layer 21 and the shaft 40 are in communication with each other, but the upper layer and the shaft do not necessarily need to be in communication with each other. In other words, the air supplied from the upper space to the upper layer only needs to pass from the upper layer through the lower layer and flow into the shaft, and does not necessarily need to flow directly from the upper layer to the shaft.
