Description

[Technical field]

[0001] The present disclosure relates to an installation structure, a support member, and an installation method. [Background technology]

[0002] When air conditioning equipment is installed indoors, the equipment may be suspended from a ceiling. The equipment is suspended from a building structure by, for example, a suspension bolt (see, for example, Patent Document 1).

[0003] Since air conditioning equipment is installed at a high position indoors, when a building shakes due to an earthquake or the like, the air conditioning equipment may shake relative to the ceiling and fall. There is also a risk of the air conditioning equipment colliding with the ceiling substrate. In Patent Document 1, braces are attached to the hanging bolts that suspend the air conditioning equipment in order to suppress the shaking of the air conditioning equipment relative to the ceiling (the braces in Patent Document 1 are fully threaded bolts P). In the example of Patent Document 1, eight braces are attached to four hanging bolts. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-124856 A Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, when installing air conditioning-related equipment, it is necessary to perform tasks such as setting anchors to attach the suspension bolts to the ceiling, attaching braces to the suspension bolts, and lifting the air conditioning-related equipment near the ceiling.

[0006] In the conventional installation structure of air conditioning-related equipment, a lot of work is required to install the air conditioning-related equipment. In addition, since it involves working at high altitudes, a lot of manpower may be required to ensure safety. The object of the present disclosure is to provide an installation structure, air conditioning-related equipment, a support member, and an installation method that can improve the work efficiency when installing air conditioning-related equipment. [Means for solving the problem]

[0007] The installation structure of a first aspect that solves this problem is an installation structure for installing air conditioning-related equipment between a building structure and a ceiling substructure, and includes a hanging member for suspending the air conditioning-related equipment from the building structure and a support member attached to the air conditioning-related equipment, and the support member is attached to the ceiling substructure.

[0008] According to this configuration, the support member connects the air conditioning equipment to the ceiling foundation, so the air conditioning equipment is prevented from shaking relative to the ceiling. Since the support member prevents the air conditioning equipment from shaking, the installation of braces is not necessary, and the labor required to install the braces can be reduced. Therefore, the work efficiency when installing the air conditioning equipment is improved.

[0009] The installation structure of a second aspect is the installation structure of the first aspect, wherein the ceiling base has a first frame and a second frame disposed away from the first frame in a first direction in a plan view, and the support member has a connection portion, a first ceiling mounting portion attached to the first frame, and a second ceiling mounting portion attached to the second frame, the connection portion extends in the first direction, the first ceiling mounting portion extends in a vertical direction with one end connected to the connection portion and the other end attached to the first frame, and the second ceiling mounting portion extends in a vertical direction with one end connected to the connection portion and the other end attached to the second frame. With this configuration, since the support member is attached to the first frame and the second frame, shaking of the air-conditioning-related equipment in the first direction can be suitably suppressed.

[0010] An installation structure according to a third aspect is the installation structure according to the second aspect, wherein the first ceiling mounting portion is formed integrally with the connecting portion, and the second ceiling mounting portion is formed integrally with the connecting portion. With this configuration, the connecting portion, the first ceiling mounting portion, and the second ceiling mounting portion are formed integrally, making it easy to handle the support member.

[0011] The installation structure of a fourth aspect is the installation structure of any one of the first to third aspects, wherein one end of the hanging member is attached to the architectural structure, and the other end of the hanging member is attached to the support member. With this configuration, since the other end of the hanging member is attached to the support member, the hanging member can hang air-conditioning-related equipment via the support member. With this configuration, there is no need to add a structure for attaching the hanging member to the air-conditioning-related equipment.

[0012] In a fifth aspect, in the installation structure of any one of the first to third aspects, one end of the hanging member is attached to the architectural structure, and the other end of the hanging member is attached to the air-conditioning-related equipment. With this configuration, the weight of the air-conditioning-related equipment can be directly supported by the architectural structure via the hanging member.

[0013] The installation structure of a sixth aspect is the installation structure of any one of the first to fifth aspects, further comprising a connecting member for connecting the air-conditioning-related equipment to the support member, the connecting member having a hanging bolt, the support member having a support connecting portion connected to the hanging bolt, the air-conditioning-related equipment having a first connecting portion connected to the hanging bolt, the first connecting portion configured to be adjustable in position relative to the hanging bolt. With this configuration, the position of the first connecting portion relative to the support member can be suitably adjusted by adjusting the position of the first connecting portion relative to the hanging bolt.

[0014] The installation structure of a seventh aspect is the installation structure of the sixth aspect, wherein the air-conditioning-related equipment has a second connecting portion that connects to the hanging bolt, and the second connecting portion connects to a portion of the hanging bolt different from the portion to which the first connecting portion connects. With this configuration, the air-conditioning-related equipment is connected to the hanging bolt at two points, so that the air-conditioning-related equipment is less likely to shake relative to the hanging bolt, and therefore shaking of the air-conditioning-related equipment relative to the support member can be suitably suppressed.

[0015] An installation structure according to an eighth aspect is the installation structure according to any one of the first to fifth aspects, further comprising a connecting member for connecting the air-conditioning-related equipment to the support member, the connecting member having a positioning member for determining a position of the air-conditioning-related equipment relative to the support member, the support member having a support connecting portion connected to the positioning member, and the air-conditioning-related equipment having a third connecting portion connected to the positioning member. According to this configuration, the position of the air-conditioning-related equipment relative to the support member can be determined by the positioning member, thereby reducing the need for work to adjust the position of the air-conditioning-related equipment relative to the support member.

[0016] According to a ninth aspect of the present invention, in the installation structure of any one of the first to eighth aspects, the suspension member is a wire. With this configuration, since it is not necessary to install suspension bolts in the architectural structure, it is possible to reduce the work required for installing suspension bolts in the architectural structure.

[0017] The installation structure of a tenth aspect is the installation structure of the ninth aspect, further comprising a wire engaging portion attached to the air conditioning-related equipment, the wire engaging portion being configured to be switchable between a first state and a second state when the air conditioning-related equipment is suspended from the architectural structure, the first state being a state in which the wire engaging portion is movable relative to the wire in a first movement direction from the ceiling substructure toward the architectural structure and is unable to move relative to the wire in a second movement direction opposite to the first movement direction, and the second state being a state in which the wire engaging portion is movable relative to the wire in the first movement direction and is able to move relative to the wire in the second movement direction.

[0018] According to this configuration, by switching the state of the wire engagement portion from the first state to the second state, the air conditioning-related equipment can be moved away from the building structure. Therefore, when the air conditioning-related equipment is suspended near the ceiling, the worker can adjust the position of the air conditioning-related equipment to match the ceiling substrate. Since the position of the air conditioning-related equipment can be suitably adjusted while the air conditioning-related equipment is suspended near the ceiling, work efficiency is improved compared to when the air conditioning-related equipment is suspended by a suspension bolt.

[0019] An installation structure according to an eleventh aspect is the installation structure according to any one of the first to tenth aspects, wherein the air conditioning-related equipment is an indoor unit of an air conditioner, a total heat exchanger, or an outdoor air processing unit. With this configuration, the indoor unit of the air conditioner, the total heat exchanger, or the outdoor air processing unit can be suitably installed on the ceiling.

[0020] An installation structure according to a twelfth aspect is the installation structure according to any one of the first to eleventh aspects, further comprising the air-conditioning-related equipment installed by the installation structure. According to this configuration, the air-conditioning-related equipment can be suitably installed on the ceiling.

[0021] A support member according to a thirteenth aspect of the present invention is a support member that is attached to air-conditioning-related equipment so as to support the air-conditioning-related equipment, and is attached to a ceiling base of a ceiling on which the air-conditioning-related equipment is installed. With this configuration, the support member suppresses shaking of the air-conditioning-related equipment relative to the ceiling. Since braces are not required when installing the air-conditioning-related equipment, work efficiency is improved compared to conventional installation structures.

[0022] The installation method according to a fourteenth aspect for solving this problem is a method for installing air conditioning-related equipment of an air conditioner between a building structure and a ceiling substrate, and includes the steps of suspending the air conditioning-related equipment from the building structure and attaching a support member to be attached to the air conditioning-related equipment to the ceiling substrate. According to this configuration, the support member prevents the air conditioning-related equipment from shaking relative to the ceiling after installation. Since no braces are required during installation, work efficiency is improved compared to conventional installation methods. [Brief description of the drawings]

The first ceiling mounting bracket 33 has a plate-shaped portion 33A extending horizontally from the first ceiling mounting part 24. The plate-shaped portion 33A is hooked onto the upper surface of the first frame 4. The plate-shaped portion 33A is bent so that the first ceiling mounting part 24 does not move in the first direction D1 relative to the first frame 4. The second ceiling mounting bracket 34 is attached to the first ceiling mounting part 24 so as to surround the first frame 4.

[0044] As shown in FIG. 6, in a state where the plate-shaped portion 33A is hooked on the upper surface of the first frame 4, the second ceiling mounting bracket 34 is attached to the first ceiling mounting part 24 by the connecting member 34A so as to surround the first frame 4. In a state where the plate-shaped portion 33A is hooked on the upper surface of the first frame 4, the first ceiling mounting part 24 can move in the second direction D2 relative to the first frame 4. Therefore, before the second ceiling mounting bracket 34 is attached to the first ceiling mounting part 24, the position of the first ceiling mounting part 24 relative to the first frame 4 in the second direction D2 can be finely adjusted. Similarly, before the second ceiling mounting bracket 34 is attached to the second ceiling mounting part 25, the position of the second ceiling mounting part 25 relative to the second frame 5 in the second direction D2 can also be finely adjusted. By the first ceiling mounting part 24 and the second ceiling mounting part 25, the position of the air-conditioning-related equipment 10 relative to the ceiling substrate 3 can be finely adjusted when attaching the support member 22 to the ceiling substrate 3. The first ceiling mounting part 24 may be attached to the first frame 4 by a method other than the first ceiling mounting bracket 33 and the second ceiling mounting bracket 34. The same applies to the second ceiling mounting part 25.

[0045] <Wire engagement part> 3, the installation structure 20 further includes a wire engaging portion 35 that is attached to the air-conditioning-related equipment 10. The hanging member 21 has the wire engaging portion 35. The installation structure 20 of the present embodiment has two wire engaging portions 35 for one support member 22. In the present embodiment, the wire engaging portions 35 are attached to the support member 22. The wire engaging portions 35 are configured so that the wire 21A passes through them in the vertical direction.

[0046] 7 illustrates the wire engaging portion 35 disposed on one end 23X side of the connection portion 23. As shown in FIG. 7, the wire engaging portion 35 has a wire engaging portion main body 36 and a wire engaging portion support 37. The wire engaging portion main body 36 has a through hole 36A through which the wire 21A passes.

The wire engaging portion 35 disposed on the other end 23Y side of the connection portion 23 is disposed so as to pass through the second wire connection hole 31B and the second ceiling mounting hole 28A.

[0047] The wire engagement portion support 37 is provided on the outer periphery of the wire engagement portion main body 36. The wire engagement portion support 37 has a plate shape extending in the horizontal direction. The size of the wire engagement portion support 37 is set so that it cannot pass through the first wire connection hole 31A and the first ceiling mounting hole 26A in the vertical direction. The wire engagement portion support 37 is arranged below the connection bar member 23A and the first arm member 26 in the vertical direction so as to support the wire engagement portion main body 36 with respect to the connection portion 23. The wire engagement portion 35 may have a wire engagement portion fitting 38 arranged above the upper surface of the connection portion 23 in the vertical direction. The wire engagement portion main body 36 is arranged so as to pass through a hole formed in the wire engagement portion fitting 38. The wire engagement portion fitting 38 is, for example, a washer.

[0048] The wire engaging portion 35 is configured to be switchable between a first state and a second state. The first state and the second state are states defined in a state in which the air-conditioning-related equipment 10 is suspended from the architectural structure 2. The first state is a state in which the wire engaging portion 35 is movable in a first movement direction DM1 relative to the wire 21A, and is not movable in a second movement direction DM2 relative to the wire 21A. The second state is a state in which the wire engaging portion 35 is movable in the first movement direction DM1 relative to the wire 21A, and is movable in the second movement direction DM2 relative to the wire 21A. The first movement direction DM1 is a direction from the ceiling foundation 3 toward the architectural structure 2 (see FIG. 1). The second movement direction DM2 is a direction opposite to the first movement direction DM1. The wire engaging portion 35 is switchable between the first state and the second state in a state in which the air-conditioning-related equipment 10 is suspended from the architectural structure 2.

[0049] The wire engaging portion 35 has a suspension state switching portion 39 that switches between a first state and a second state. The suspension state switching portion 39 includes a pin 39A provided below the wire engaging portion 35. The wire engaging portion 35 is configured to switch from the first state to the second state, for example, by operating the suspension state switching portion 39. The wire engaging portion 35 may have a configuration different from that of this embodiment as long as it is configured to be switchable between the first state and the second state in a state in which the air-conditioning-related equipment 10 is suspended from the building structure 2. The internal structure of the wire engaging portion 35 may be the structure disclosed in Japanese Utility Model Application Publication No. 58-73163, Japanese Utility Model Application Publication No. 62-52469, etc.

[0050] <Connecting parts> 3, the installation structure 20 further includes a connecting member 40 that connects the air-conditioning-related equipment 10 to the support member 22. The connecting member 40 in this embodiment has a hanging bolt 41. The installation structure 20 in this embodiment has two connecting members 40 for one support member 22.

[0051] As shown in Fig. 4, in this embodiment, the support joint portion 32 of the support member 22 is joined to a hanging bolt 41. The connecting member 40 has a hanging bolt 41 that passes through the first ceiling mounting hole 26A and the first connection hole 30A, and a hanging bolt 41 that passes through the second ceiling mounting hole 28A and the second connection hole 30B (see Fig. 5). The hanging bolt 41 is joined to the support member 22 by a support joint member 42. The support joint member 42 is, for example, a nut.

[0052] In this embodiment, the first connecting portion 14 of the air conditioning-related equipment 10 is connected to the hanging bolt 41. In this embodiment, the second connecting portion 15 of the air conditioning-related equipment 10 is connected to the hanging bolt 41. A first connecting member 43 connects the first connecting portion 14 to the hanging bolt 41. A second connecting member 44 connects the second connecting portion 15 to the hanging bolt 41. The portion of the hanging bolt 41 to which the second connecting portion 15 is connected is located above the portion of the hanging bolt 41 to which the first connecting portion 14 is connected.

[0053] The first connecting portion 14 is configured to be able to adjust the position of the first connecting portion 14 relative to the hanging bolt 41. The first connecting member 43 is, for example, a nut arranged to sandwich the first connecting portion 14. By adjusting the position of the first connecting member 43 relative to the hanging bolt 41, the position of the first connecting portion 14 relative to the hanging bolt 41 in the up-down direction can be adjusted. The second connecting portion 15 is connected to a portion of the hanging bolt 41 different from the portion to which the first connecting portion 14 is connected. The second connecting member 44 is, for example, a nut arranged to sandwich the second connecting portion 15. By adjusting the position of the second connecting member 44 relative to the hanging bolt 41, the position of the second connecting portion 15 relative to the hanging bolt 41 in the up-down direction can be adjusted.

[0054] As shown in Fig. 5, the hanging bolt 41 is arranged to pass through the first connection hole 30A and the first ceiling mounting hole 26A. Since the first ceiling mounting hole 26A and the first connection hole 30A are elongated holes whose major diameters extend in the first direction D1, the position of the hanging bolt 41 relative to the support member 22 in the first direction D1 is adjustable. Similarly, the hanging bolt 41 is arranged to pass through the second connection hole 30B and the second ceiling mounting hole 28A, so the position of the hanging bolt 41 relative to the support member 22 in the first direction D1 is adjustable. Therefore, the installation structure 20 can adjust the position of the connecting member 40 relative to the support member 22 in the first direction D1 according to the dimensions of the air-conditioning-related equipment 10, etc.

[0055] A method for installing air-conditioning-related equipment 10 will be described with reference to Fig. 8 to Fig. 10. The installation method is a method for installing air-conditioning-related equipment 10 of an air conditioner between a building structure 2 and a ceiling substrate 3. The installation method includes a step of suspending air-conditioning-related equipment 10 from the building structure 2, and a step of attaching a support member 22 to be attached to the air-conditioning-related equipment 10 to the ceiling substrate 3. In the installation method, a lifter 91 is used to lift the air-conditioning-related equipment 10 up to near the ceiling 1.

[0056] 8 shows a process of preparing to suspend the air-conditioning-related equipment 10 from the architectural structure 2. The preparation for suspending the air-conditioning-related equipment 10 from the architectural structure 2 is performed by a worker 92. In the installation method of the present disclosure, the worker may be a single person. A support member 22 is attached to the air-conditioning-related equipment 10 placed on a lifter 91. A wire 21A is attached to the support member 22 via a wire engagement portion 35. The wire 21A is attached to the architectural structure 2 via an anchor 2A.

[0057] 9 shows the process of suspending the air-conditioning-related equipment 10 from the building structural body 2. The air-conditioning-related equipment 10 is lifted up to near the ceiling 1 by a lifter 91. In this process, the wire engagement portion 35 is in the first state. As the air-conditioning-related equipment 10 approaches near the ceiling 1, the wire 21A is pulled downward so as not to slacken. Because the wire engagement portion 35 is in the first state, the wire 21A can move downward relative to the wire engagement portion 35.

[0058] The air conditioning-related equipment 10 is temporarily lifted up to a height above the height at which the ceiling substructure 3 will actually be placed. In FIG. 9, the height at which the ceiling substructure 3 will actually be placed is indicated by a two-dot chain line. After the ceiling substructure 3 is lifted up to a height above the height at which it will actually be placed, the lifter is withdrawn, but since the wire engagement portion 35 is in the first state, the air conditioning-related equipment 10 does not fall. The wire 21A may be wound in a loop so that it does not hang down (see FIG. 10). Since the air conditioning-related equipment 10 is lifted up to a height above the height at which the ceiling substructure 3 will actually be placed, it is easy to assemble the ceiling substructure 3 when the air conditioning-related equipment 10 is lifted up near the ceiling 1.

[0059] FIG. 10 shows a process in which the support member 22 to be attached to the air conditioning-related equipment 10 is attached to the ceiling substrate 3. The first ceiling attachment part 24 is attached to the first frame 4, and the second ceiling attachment part 25 is attached to the second frame 5. In this process, when the support member 22 is attached to the ceiling substrate 3, the wire engagement part 35 is switched from the first state to the second state. Therefore, the air conditioning-related equipment 10 that has been raised above the height at which the ceiling substrate 3 is disposed can be lowered to the height at which the ceiling substrate 3 is disposed. In addition, the position of the air conditioning-related equipment 10 can be finely adjusted according to the position of the air outlet of the indoor unit 11. When the air conditioning-related equipment 10 is the indoor unit 11, a decorative cover 12 is attached below the indoor unit 11 (see FIG. 1).

[0060] A first effect of this embodiment will be described. According to the conventional installation structure, the air conditioning-related equipment is suspended from the building structure by the suspension bolt. The suspension bolt is connected to an anchor driven into the building structure. In such a conventional installation structure, when a building shakes due to an earthquake or the like, the air conditioning-related equipment shakes relative to the building, and stress caused by the vibration may act on the building structure, the anchor, and the suspension bolt. As an example, the stress caused by the vibration may cause the anchor to loosen relative to the building structure, the suspension bolt to loosen relative to the anchor, and the suspension bolt to break. In the installation structure 20 of this embodiment, the air conditioning-related equipment 10 is supported on the ceiling substrate 3 by the support member 22, so that the air conditioning-related equipment 10 is suppressed from shaking relative to the building. In addition, since the air conditioning-related equipment 10 is suspended from the building structure 2 by the wire 21A, even if the position of the air conditioning-related equipment 10 relative to the building structure 2 changes, the building structure 2 and the anchor 2A are unlikely to be loaded. Therefore, even if the air-conditioning-related equipment 10 shakes relative to the building, the generation of stress due to vibration in the building structure 2 and the anchors 2A is suppressed compared to the case where the air-conditioning-related equipment 10 is suspended by suspension bolts.

[0061] A second effect of this embodiment will be described. In the conventional installation structure described above, the task of placing the air conditioning-related equipment near the ceiling required multiple workers. For example, when lifting the air conditioning-related equipment near the ceiling by a lifter, in addition to the worker who operates the lifter, a worker who supports the air conditioning-related equipment so that it does not fall from the lifter was required. In the installation structure 20 of this embodiment, when the air conditioning-related equipment 10 is lifted, the wire engagement portion 35 is switched to the first state so that the air conditioning-related equipment 10 does not fall from the lifter 91. Therefore, in the installation structure 20, when the air conditioning-related equipment 10 is lifted near the ceiling, a worker who supports the air conditioning-related equipment 10 is not required. Although the task of eliminating the slack in the wire 21A with respect to the wire engagement portion 35 is required, this task can be performed by the worker 92 who operates the lifter 91.

[0062] The effects of this embodiment will be described. (1-1) The installation structure 20 comprises a hanging member 21 that suspends the air-conditioning-related equipment 10 from the building structural body 2, and a support member 22 that is attached to the air-conditioning-related equipment 10. The support member 22 is attached to the ceiling substrate 3. With this configuration, the support member 22 connects the air-conditioning-related equipment 10 to the ceiling substrate 3, thereby suppressing the air-conditioning-related equipment 10 from shaking relative to the ceiling 1. Since the support member 22 can suppress the shaking of the air-conditioning-related equipment 10, the installation of a brace is not required, and the labor required to install the brace can be reduced. This improves the work efficiency when installing the air-conditioning-related equipment 10.

[0063] (1-2) The ceiling base 3 has a first frame 4 and a second frame 5. The support member 22 has a connection portion 23, a first ceiling mounting portion 24, and a second ceiling mounting portion 25. The connection portion 23 extends in a first direction D1. The first ceiling mounting portion 24 extends in the vertical direction such that one end 24X is connected to the connection portion 23 and the other end 24Y is attached to the first frame 4. The second ceiling mounting portion 25 extends in the vertical direction such that one end 25X is connected to the connection portion 23 and the other end 25Y is attached to the second frame 5. With this configuration, the support member 22 is attached to the first frame 4 and the second frame 5, so that shaking of the air-conditioning-related equipment 10 in the first direction D1 can be suitably suppressed.

[0064] (1-3) The first ceiling mounting portion 24 is formed integrally with the connection portion 23. The second ceiling mounting portion 25 is formed integrally with the connection portion 23. According to this configuration, the connection portion 23, the first ceiling mounting portion 24, and the second ceiling mounting portion 25 are formed integrally, making it easy to handle the support member 22.

[0065] (1-4) One end 21X of hanging member 21 is attached to building structural body 2. The other end 21Y of hanging member 21 is attached to supporting member 22. With this configuration, since the other end 21Y of hanging member 21 is attached to supporting member 22, hanging member 21 can suspend air-conditioning-related equipment 10 via supporting member 22. With this configuration, there is no need to add a structure for attaching hanging member 21 to air-conditioning-related equipment 10.

[0066] (1-5) The installation structure 20 further includes a connecting member 40. The connecting member 40 has a hanging bolt 41. The support member 22 has a support joint 32. The air-conditioning-related equipment 10 has a first joint 14. The first joint 14 is configured so that the position of the first joint 14 relative to the hanging bolt 41 is adjustable. With this configuration, the position of the air-conditioning-related equipment 10 relative to the support member 22 can be suitably adjusted by adjusting the position of the first joint 14 relative to the hanging bolt 41.

[0067] (1-6) The air-conditioning-related equipment 10 has a second connecting portion 15. The second connecting portion 15 is connected to a portion of the hanging bolt 41 that is different from the portion to which the first connecting portion 14 is connected. With this configuration, the air-conditioning-related equipment 10 is connected to the hanging bolt 41 at two points, making it difficult for the air-conditioning-related equipment 10 to swing relative to the hanging bolt 41, and therefore swinging of the air-conditioning-related equipment 10 relative to the support member 22 can be suitably suppressed.

[0068] (1-7) The hanging member 21 is a wire 21A. With this configuration, it is not necessary to install the hanging bolts 41 in the architectural structure 2, and therefore the amount of work required to install the hanging bolts 41 in the architectural structure 2 can be reduced. Also, compared to the case where the air-conditioning-related equipment 10 is suspended by the hanging bolts 41, it is easier to adjust the position of the air-conditioning-related equipment 10 in the horizontal direction when installing the air-conditioning-related equipment 10.

[0069] (1-8) The installation structure 20 further includes a wire engaging portion 35. The wire engaging portion 35 is configured to be switchable between a first state and a second state while the air-conditioning-related equipment 10 is suspended from the architectural structure 2. With this configuration, the state of the wire engaging portion 35 is switched from the first state to the second state, so that the air-conditioning-related equipment 10 can move away from the architectural structure 2. Therefore, the worker 92 can adjust the position of the air-conditioning-related equipment 10 to match the ceiling substrate 3 while the air-conditioning-related equipment 10 is suspended near the ceiling 1. Since the position of the air-conditioning-related equipment 10 can be suitably adjusted while the air-conditioning-related equipment 10 is suspended near the ceiling 1, work efficiency is improved compared to the case where the air-conditioning-related equipment 10 is suspended from the architectural structure 2 by a suspension bolt.

[0070] (1-9) The air conditioning-related equipment 10 is an indoor unit 11 of an air conditioner. According to this configuration, the indoor unit 11 of the air conditioner can be suitably installed on the ceiling 1.

[0071] (1-10) The installation structure 20 further includes the air-conditioning-related equipment 10 that is installed by the installation structure 20. According to this configuration, the air-conditioning-related equipment 10 can be suitably installed on the ceiling 1.

[0072] (1-11) The support member 22 is attached to the ceiling foundation 3 arranged horizontally alongside the air-conditioning-related equipment 10. With this configuration, the support member 22 suppresses shaking of the air-conditioning-related equipment 10 relative to the ceiling 1. Since braces are no longer required to install the air-conditioning-related equipment 10, work efficiency is improved compared to conventional installation structures.

[0073] (1-12) The method for installing the air-conditioning-related equipment 10 includes a step of suspending the air-conditioning-related equipment 10 from the building structure 2, and a step of attaching a support member 22 to be attached to the air-conditioning-related equipment 10 to the ceiling base 3. According to this configuration, since it is not necessary to install a brace in the building structure 2, work efficiency is improved compared to conventional installation methods.

[0074] <Second embodiment> The installation structure 20, support member 22, and installation method of the present embodiment will be described with reference to Fig. 11. In this embodiment, the air-conditioning mounting bracket 17 is omitted from the air-conditioning-related equipment 10 of the first embodiment. The same reference numerals as in the first embodiment are used for the configurations of the installation structure 20, support member 22, and installation method of the present embodiment that are common to the first embodiment, and duplicated explanations will be omitted.

[0075] In this embodiment, the air conditioning-related equipment 10 does not include the second connecting portion 15. In this embodiment, the second connecting member 44 is omitted. The first connecting portion 14 in this embodiment is provided on the housing 10H of the air conditioning-related equipment 10. The first connecting portion 14 in this embodiment may be the air conditioning mounting portion 16. The air conditioning mounting hole 16A of the air conditioning mounting portion 16 may be the first connecting hole 14A of the first connecting portion 14. The first connecting member 43 is arranged to sandwich the air conditioning mounting portion 16 of the air conditioning-related equipment 10.

[0076] In this embodiment, only the first coupling portion 14 is coupled to the hanging bolt 41 of the connecting member 40. In this embodiment, the first coupling portion 14 may be provided at a location other than the air conditioning mounting portion 16. For example, the first coupling portion 14 may be provided on the upper surface of the housing 10H.

[0077] The effects of this embodiment will be described. The first coupling portion 14 is provided on the housing 10H of the air-conditioning-related equipment 10. With this configuration, the connecting member 40 can be directly attached to the housing 10H of the air-conditioning-related equipment 10, so that the configuration of the installation structure 20 can be simplified.

[0078] <Third embodiment> The installation structure 20, support member 22, and installation method of this embodiment will be described with reference to Figures 12 to 14. In the installation structure 20 of this embodiment, the connecting member 40 has a positioning member 52 instead of the hanging bolt 41. In the installation structure 20, support member 22, and installation method of this embodiment, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and duplicated descriptions will be omitted.

[0079] <Supporting member> As shown in FIG. 12, in this embodiment, the support joint 32 is formed in the first ceiling mounting part 24 and the second ceiling mounting part 25. A positioning member 52 is provided as a connecting member 40 so as to bridge the support joint 32 in the first ceiling mounting part 24 and the support joint 32 in the second ceiling mounting part 25. FIG. 14 illustrates the support joint 32 formed in the first ceiling mounting part 24. In this embodiment, the first connection hole 30A and the second connection hole 30B may be omitted from the connection part 23. Also, the first ceiling mounting hole 26A of the first ceiling mounting part 24 and the second ceiling mounting hole 28A of the second ceiling mounting part 25 do not have to be elongated holes.

[0080] <Air conditioning related equipment> As shown in FIG. 13, the air conditioning-related equipment 10 has a third joint portion 51. The third joint portion 51 is formed in the air conditioning mounting bracket 17. The third joint portion 51 has a plate shape extending in a generally horizontal direction. A third joint hole 51A is formed in the third joint portion 51. In this embodiment, in addition to the third joint portion 51, the second joint portion 15 of the first embodiment may be formed in the air conditioning mounting bracket 17. The second joint portion 15 of the first embodiment may also serve as the third joint portion 51. The second joint hole 15A of the first embodiment may also serve as the third joint hole 51A. The first joint portion 14 of this embodiment is joined to the air conditioning mounting portion 16 by a joint member 14X. The joint member 14X is, for example, a bolt and a nut.

[0081] <Connecting parts> The connecting member 40 of this embodiment has a positioning member 52 that determines the position of the air-conditioning-related equipment 10 relative to the support member 22. The support coupling portion 32 of this embodiment is coupled to the positioning member 52. The positioning member 52 is attached to the support member 22 and the air-conditioning-related equipment 10, thereby determining the position of the air-conditioning-related equipment 10 relative to the support member 22. The positioning member 52 is attached to the air-conditioning-related equipment 10 via the air-conditioning mounting bracket 17. The positioning member 52 may be attached directly to the housing 10H of the air-conditioning-related equipment 10. The positioning member 52 may have a plate-shaped member 53 extending in the first direction D1.

[0082] As shown in FIG. 13, the plate member 53 is formed of a first plate member 53A extending in the vertical direction and a second plate member 53B extending in the horizontal direction. The lower end of the first plate member 53A is connected to the second plate member 53B. The support joint 32 of this embodiment is connected to the first plate member 53A of the positioning member 52. One end of the first plate member 53A is connected to the support joint 32 of the first ceiling mounting part 24 by a joint member 53X (see FIG. 14). The other end of the first plate member 53A is connected to the support joint 32 of the second ceiling mounting part 25 by a joint member 53X (see FIG. 12).

[0083] The third connecting portion 51 is connected to the positioning member 52. The third connecting portion 51 is connected to the second plate-shaped member 53B by a connecting member 53Y. The connecting members 53X and 53Y are, for example, a bolt and a nut.

[0084] The operation of this embodiment will now be described. The position of the support joint portion 32 in the support member 22 can be set according to the height of the air-conditioning-related equipment 10 relative to the ceiling substrate 3. By attaching the plate-shaped member 53 to the support member 22, the position of the air-conditioning-related equipment 10 relative to the support member 22 can be determined according to the height of the air-conditioning-related equipment 10 relative to the ceiling substrate 3. Before lifting the air-conditioning-related equipment 10 near the ceiling 1, the position of the air-conditioning-related equipment 10 relative to the support member 22 can be determined.

[0085] The effects of this embodiment will be described. Connecting member 40 has positioning member 52. Support member 22 has support coupling portion 32 that couples to positioning member 52. Air-conditioning-related equipment 10 has third coupling portion 51 that couples to positioning member 52. With this configuration, positioning member 52 can determine the position of air-conditioning-related equipment 10 relative to support member 22, thereby reducing the need for work to adjust the position of air-conditioning-related equipment 10 relative to support member 22.

[0086] <Fourth embodiment> The installation structure 20, the support member 22, and the installation method of this embodiment will be described with reference to Fig. 15 to Fig. 17. In this embodiment, the wire engagement portion 35 is attached to the air-conditioning-related equipment 10. The same reference numerals as in the first embodiment are used for the configurations of the installation structure 20, the support member 22, and the installation method of this embodiment that are common to the first embodiment, and duplicated descriptions will be omitted.

[0087] 15 , in this embodiment, one end 21X of the hanging member 21 is attached to the building structural body 2. The other end 21Y of the hanging member 21 is attached to the air-conditioning-related equipment 10. The hanging member 21 in this embodiment is directly connected to the air-conditioning mounting bracket 17 of the air-conditioning-related equipment 10. The other end 21Y of the hanging member 21 is attached to the air-conditioning mounting bracket 17 of the air-conditioning-related equipment 10.

[0088] 16, in this embodiment, a wire connection hole 61 is formed in the second coupling part 15 of the air conditioning mounting bracket 17. The wire connection hole 61 is formed side by side with the second coupling hole 15A. In this embodiment, the wire engagement part main body 36 of the wire engagement part 35 is positioned so as to pass through the wire connection hole 61. The size of the wire engagement part support material 37 is set so that it cannot pass through the wire connection hole 61 in the vertical direction.

[0089] Fig. 17 is a schematic diagram of the installation structure 20 viewed from the outside of the first frame 4 in a direction along the first direction D1. As shown in Fig. 17, the wire engagement portion 35 of this embodiment is disposed below the connection portion 23 of the support member 22 in the up-down direction. The wire engagement portion 35 of this embodiment is located between the air-conditioning-related equipment 10 and the support member 22 in the horizontal direction.

[0090] The effects of this embodiment will be described. One end 21X of the hanging member 21 is attached to the building structure 2, and the other end 21Y of the hanging member 21 is attached to the air-conditioning-related equipment 10. According to this configuration, the hanging member 21 allows the building structure 2 to directly support the weight of the air-conditioning-related equipment 10 via the hanging member 21.

[0091] <Modification> In addition to the above-described embodiments, the installation structure, support member, and installation method of the present disclosure may be configured in the following modified examples, or in a form that combines at least two modified examples that are not mutually contradictory.

[0092] 18, in the second embodiment, the other end 21Y of the hanging member 21 may be attached to the air-conditioning-related equipment 10. In this modification, the other end 21Y of the hanging member 21 may be attached to the air-conditioning mounting portion 16 of the air-conditioning-related equipment 10.

[0093] 19 , in the third embodiment, the other end 21Y of the hanging member 21 may be attached to the air-conditioning-related equipment 10. In this modification, the other end 21Y of the hanging member 21 may be attached to an air-conditioning mounting bracket 17 of the air-conditioning-related equipment 10.

[0094] As shown in FIG. 20, the first ceiling mounting part 24 may be in contact with the outer surface of the first frame 4. The second ceiling mounting part 25 may be in contact with the outer surface of the second frame 5. In this modification, the support member 22 may have a first movable part 71 and a second movable part 72. The first movable part 71 is configured so that the first bar member 27 of the first ceiling mounting part 24 can move along the first direction D1 relative to the connection bar member 23A of the connection part 23. The second movable part 72 is configured so that the second bar member 29 of the second ceiling mounting part 25 can move along the first direction D1 relative to the connection bar member 23A of the connection part 23. In this modification, the air-conditioning-related equipment 10 is lifted up near the ceiling 1 in a state in which the distance between the first bar member 27 and the second bar member 29 is set to be larger than the distance between the outer surface of the first frame 4 and the outer surface of the second frame 5. When the support member 22 is connected to the ceiling substrate 3, the distance between the first bar member 27 and the second bar member 29 is adjusted by the first movable part 71 and the second movable part 72 to match the distance between the outer surfaces of the first frame 4 and the second frame 5. In this manner, in this modified example, the distance between the first bar member 27 and the second bar member 29 can be adjusted according to the distance between the actually positioned first frame 4 and second frame 5.

[0095] The other end 24Y of the first ceiling mounting part 24 may be attached to the third frame 6, and the other end 25Y of the second ceiling mounting part 25 may be attached to the fourth frame 7. In this modification, whether the ceiling mounting parts 24, 25 are attached to the frames 4, 5, or to the frames 6, 7 can be determined depending on the installation status of the piping 13, etc.

[0096] The hanging member 21 may be a hanging bolt. Even if the hanging member 21 is a hanging bolt, in the installation structure 20 including the support member 22, there is no need to provide a brace on the hanging bolt of the hanging member 21, and therefore the work required for installing a brace can be reduced.

[0097] The first ceiling mounting portion 24 may be formed integrally with the connection portion 23. The second ceiling mounting portion 25 may be formed integrally with the connection portion 23. The first ceiling mounting portion 24 may be formed inseparably with the connection portion 23. The second ceiling mounting portion 25 may be formed inseparably with the connection portion 23. For example, the first ceiling mounting portion 24 and the connection portion 23 are formed integrally by pressing a metal member. For example, the second ceiling mounting portion 25 and the connection portion 23 are formed integrally by pressing a metal member.

[0098] In the third embodiment, the shape of the positioning member 52 is not limited to that of the embodiment, so long as it can determine the position of the air-conditioning-related equipment 10 relative to the support member 22. The positioning member 52 may be formed of a plate-like member extending in the vertical or horizontal direction, or may include a rod-like member.

[0099] 21 , the air conditioning-related equipment 10 may be an indoor unit 11 of an air conditioner, a total heat exchanger 81, or an outdoor air processing unit 82. The air conditioning-related equipment 10 may be the total heat exchanger 81. According to this modification, the total heat exchanger 81 can be suitably installed on the ceiling 1.

[0100] 22, the air conditioning-related equipment 10 may be an outside air processing device 82. The outside air processing device 82 is, for example, an air purifier. According to this modification, the outside air processing device 82 can be suitably installed on the ceiling 1.
