[0045] [Support structure] The support section 11 may be made up of a plurality of members, or may be made up of a single member. In this embodiment, the support section 11 is made up of a plurality of members. Examples of the support section 11 will be described below.

[0046] The support part 11 includes a horizontal bar 30, a first vertical bar 31 connected to the horizontal bar 30, and a second vertical bar 32 connected to the horizontal bar 30. The horizontal bar 30, the first vertical bar 31, and the second vertical bar 32 are made of metal. The first vertical bar 31 is fixed to an end of the horizontal bar 30. The second vertical bar 32 is fixed to an end of the horizontal bar 30 opposite to the end to which the first vertical bar 31 is fixed.

[0047] The cross bar 30, the first vertical bar 31, and the second vertical bar 32 may have a groove-shaped cross section. The groove-shaped cross section structure improves the strength of the support member 10.

[0048] The horizontal bar 30 extends horizontally in an attached state in which the support member 10 is attached to the ceiling substrate 6 (hereinafter, referred to as the attached state of the support member 10). The horizontal bar 30 is provided with a fixing hole 11C. The fixing hole 11C is configured so that the connecting bolt 20A of the hanging member 20 can be inserted therethrough.

[0049] The first vertical bar 31 and the second vertical bar 32 extend in the up-down direction when the support member 10 is attached. The first vertical bar 31 is fixed to an end of the horizontal bar 30 with a bolt. The second vertical bar 32 is fixed to an end of the horizontal bar 30 opposite the end to which the first vertical bar 31 is fixed with a bolt. The second vertical bar 32 is disposed parallel to the first vertical bar 31.

[0050] A first connecting portion 13 is provided at the lower end of the first vertical bar 31. A hole through which a bolt is inserted is provided in the first connecting portion 13. The first connecting portion 13 is connected to the frame 7 by the bolt. A second connecting portion 14 is provided at the lower end of the second vertical bar 32. A hole through which a bolt is inserted is provided in the second connecting portion 14. The second connecting portion 14 is connected to the frame 7 by the bolt.

[0051] In the attached state of the support member 10, the second coupling portion 14 is coupled to the same frame 7 as the frame 7 to which the first coupling portion 13 is coupled. The second coupling portion 14 may be coupled to a frame 7 different from the frame 7 to which the first coupling portion 13 is coupled.

[0052] The support part 11 may be composed of one member. In this case, the support part 11 is formed by bending one rod-shaped metal member with a press. Alternatively, the support part 11 may be formed by pressing a plate-shaped metal member.

[0053] [Operation of the embodiment] Conventionally, the air-conditioning-related item 1 is placed in the ceiling space above the ceiling substrate 6 by being suspended by a suspension bolt. In this case, the suspension bolt needs to be set to a predetermined length, which takes time. Positioning the air-conditioning-related item 1 relative to the suspension bolt also takes time. In addition, when the air-conditioning-related item 1 is suspended by a suspension bolt, the air-conditioning-related item 1 also sways with the shaking of the building due to an earthquake or the like, so the air-conditioning-related item 1 is engaged with the ceiling substrate 6 to prevent the shaking. For example, in the case of a duct 2A or a refrigerant pipe 2C as the air-conditioning-related item 1, it is connected to the frame 7 of the ceiling substrate 6 by an auxiliary member (e.g., a pipe support member). At the site, the installation of the auxiliary member is time-consuming. When there are few workers, the installation of the air-conditioning-related item 1 takes a lot of time.

[0054] Furthermore, if the number of air conditioning-related facilities 3 arranged in the attic space increases, the number of ducts 2A or refrigerant pipes 2C will increase accordingly. This will result in an increase in the number of hanging bolts arranged in the attic space, which can cause a problem in that it becomes difficult to arrange the ducts 2A or refrigerant pipes 2C.

[0055] The support member 10 of this embodiment supports the air-conditioning-related item 1, and is fixed to the ceiling substrate 6. The support member 10 has a first connecting portion 13 and a second connecting portion 14 that are connected to the ceiling substrate 6. This makes it easy to connect the support member 10 to the ceiling substrate 6.

[0056] In addition, since the air-conditioning-related item 1 is fixed to the ceiling foundation 6 via the support member 10, the number of suspension bolts suspended from the architectural structure 5 can be reduced. This improves the ease of installation of the air-conditioning-related item 1.

[0057] [Effects of the embodiment] The effects of this embodiment will be described. (1) The support member 10 includes a support portion 11, a first connecting portion 13, and a second connecting portion 14. The support portion 11 is configured so that an air-conditioning-related item 1 can be placed under the support member 10 with the first connecting portion 13 and the second connecting portion 14 connected to the ceiling substrate 6.

[0058] Because the support member 10 has a first connecting portion 13 and a second connecting portion 14 that connect to the ceiling substrate 6, the support member 10 can be easily connected to the ceiling substrate 6. When the support member 10 is connected to the ceiling substrate 6, the air-conditioning-related item 1 is supported by the support member 10. In this manner, the air-conditioning-related item 1 can be easily supported.

[0059] (2) The support member 10 supports the air-conditioning piping-related item 2. The support portion 11 of the support member 10 is configured so that, when the first connecting portion 13 and the second connecting portion 14 are connected to the ceiling substrate 6, a gap is provided between the air-conditioning piping-related item 2 supported by the support portion 11 and the ceiling substrate 6. With this configuration, the air-conditioning piping-related item 2 can be easily positioned at a predetermined height relative to the ceiling substrate 6 without the air-conditioning piping-related item 2 coming into contact with the ceiling substrate 6.

[0060] If the air conditioning piping-related item 2 is placed directly on the ceiling substrate 6, condensation may occur in the area of ​​the air conditioning piping-related item 2 that comes into contact with the ceiling substrate 6. Condensation may cause deterioration of the air conditioning piping-related item 2. In this regard, since the air conditioning piping-related item 2 can be supported without coming into contact with the ceiling substrate 6, deterioration caused by condensation in the contact area as described above can be suppressed.

[0061] (3) The support portion 11 of the support member 10 has a position adjustment portion 29. The position adjustment portion 29 is configured to be able to adjust the position of the hanging member 20 that suspends the air-conditioning piping-related item 2 from the support portion 11. With this configuration, the position of the air-conditioning piping-related item 2 with respect to the support portion 11 can be adjusted.

[0062] (4) The support member 10 supports the air-conditioning-related equipment 3. The support parts 11 of the support member 10 are configured so that, when the support parts 11 are in a connected state, the bottom surface 3B of the air-conditioning-related equipment 3 supported by the support parts 11 is positioned higher than the underside 6A of the ceiling substrate 6, at the same position as the underside 6A, or at a lower position than the underside 6A. With this configuration, the air-conditioning-related equipment 3 can be easily positioned at a predetermined height relative to the ceiling substrate 6.

[0063] <Second embodiment> A support member 10 according to a second embodiment will be described with reference to Figures 4 and 5. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0064] The support member 10 has a structure that allows it to be suspended from the architectural structure 5. With the structure in which the support member 10 is suspended from the architectural structure 5, the load of the air-conditioning related item 1 can be distributed between the support member 10 and the architectural structure 5.

[0065] With reference to FIG. 4, the support member 10 including the suspension structure will now be described. The support member 10 further includes a wire 35 and a wire engaging portion 36 movably engaged with the wire 35. The wire 35 is for suspending the support member 10 from an architectural structure 5 (e.g., a slab). The wire engaging portion 36 movably engages with the wire 35. The support member 10 is movably attached to the wire 35 via the wire engaging portion 36.

[0066] An upper end of the wire 35 is connected to an anchor driven into the architectural structural body 5. The wire 35 is hung down from the architectural structural body 5. The support member 10 is supported by the wire 35 via a wire engaging portion 36. The wire engaging portion 36 is provided on the wire 35 so as to be movable only upward, as described later. Since the wire engaging portion 36 cannot move downward, the support member 10 is supported by the wire 35 via the wire engaging portion 36.

[0067] The wire engaging portion 36 has a through hole through which the wire 35 passes. The wire engaging portion 36 engages with the wire 35 by an internal structure provided in the through hole. Examples of the internal structure are disclosed in Japanese Utility Model Application Publication No. 58-73163 or Japanese Utility Model Application Publication No. 62-52469. The internal structure is not limited to these disclosed techniques.

[0068] The wire engagement portion 36 is configured to be switchable between an engaged state and a released state. The engaged state indicates a state in which the wire engagement portion 36 can move relative to the wire 35 only in a first direction and cannot move in a second direction opposite to the first direction. The released state indicates a state in which the wire engagement portion 36 can move relative to the wire 35 in both the first and second directions.

[0069] The wire engaging part 36 is attached to the wire 35 so that the movable direction of the wire engaging part 36 (i.e., the first direction) coincides with the upward direction with respect to the wire 35 hanging down from the architectural structure 5. When the wire engaging part 36 is in an engaged state, the wire engaging part 36 is movable only upward with respect to the wire 35.

[0070] 5, the wire engagement portion 36 has a switching portion 37 that switches between an engaged state and a released state. The switching portion 37 acts on the internal structure of the wire engagement portion 36. When the switching portion 37 is operated, the wire engagement portion 36 switches from one of the engaged state and the released state to the other.

[0071] The function of the wire engagement portion 36 will now be described. The support member 10 can move upwards while remaining engaged with the wire 35 hanging from the architectural structure 5. In contrast, when the support member 10 is moved downwards with respect to the wire 35 hanging from the architectural structure 5, the wire engagement portion 36 is moved downwards in a released state. When the wire engagement portion 36 is in an engaged state, the wire engagement portion 36 cannot move downwards with respect to the wire 35. For this reason, when the wire engagement portion 36 is in an engaged state, if the weight of the support member 10 or the weight of the air-conditioning-related item 1 is applied to the wire engagement portion 36, the wire engagement portion 36 stops in a stable state at a predetermined position.

[0072] [effect] The support member 10 includes a wire 35 and a wire engagement portion 36 that movably engages with the wire 35. The support member 10 is movably attached to the wire 35 via the wire engagement portion 36. Therefore, the support member 10 can be suspended from the architectural structure 5 by the wire 35. And, because the support member 10 can be moved relative to the wire 35, the air-conditioning-related item 1 can be easily positioned at a predetermined height. Also, the load of the air-conditioning-related item 1 applied to the support member 10 is distributed not only to the ceiling substrate 6 but also to the architectural structure 5. This makes it possible to reduce the load applied to the ceiling substrate 6.

[0073] The wire 35 may be provided to prevent the air conditioning-related item 1 from falling. In this case, the support member 10 is connected to the ceiling substrate 6 so that the wire 35 is slack. Such an installation prevents the ceiling substrate 6 from being pulled by the wire 35, and therefore deterioration of the ceiling substrate 6 can be suppressed in the event of shaking that causes the ceiling substrate 6 to bend up and down.

[0074] <Third embodiment> A support member 10 according to a third embodiment will be described with reference to Fig. 6. In this embodiment, configurations common to the first embodiment are given the same reference numerals as the configurations of the first embodiment, and descriptions of overlapping configurations will be omitted.

[0075] In this embodiment, the support member 10 further includes a connecting metal fitting 40 in addition to the configuration of the support member 10 in the first embodiment. The connecting metal fitting 40 is a metal fitting for connecting the support member 10 to the frame 7 of the ceiling substructure 6. Specifically, the connecting metal fitting 40 connects the first vertical bar 31 to the frame 7 of the ceiling substructure 6. The connecting metal fitting 40 also connects the second vertical bar 32 to the frame 7 of the ceiling substructure 6.

[0076] The connecting fitting 40 includes a first fitting 41 and a second fitting 46 that engages with the first fitting 41. The first fitting 41 is fixed to the support portion 11 near the first connecting portion 13 or the second connecting portion 14. The first fitting 41 has a fitting fixing portion 42 that is fixed to the support portion 11, and a receiving portion 43 that protrudes from the fitting fixing portion 42. The receiving portion 43 is disposed on the upper surface of the frame 7. When the receiving portion 43 is placed on the frame 7, the load of the support member 10 is applied to the frame 7. The first fitting 41 further has a first engagement protrusion 44 with which the second fitting 46 engages, and a second engagement protrusion 45 with which the second fitting 46 engages. The first engagement protrusion 44 is provided on the fitting fixing portion 42. The second engagement protrusion 45 protrudes from the receiving portion 43.

[0077] The second metal fitting 46 is configured so that the frame 7 can be sandwiched between the first metal fitting 41 and the second metal fitting 46. The second metal fitting 46 has a first engagement hole 47 through which the first engagement protrusion 44 is inserted, a second engagement hole 48 through which the second engagement protrusion 45 is inserted, and a second metal fitting coupling part 49. The second metal fitting coupling part 49 is coupled to the support member 10 directly or via the first metal fitting 41. The second metal fitting coupling part 49 is fixed to the frame 7 by a bolt in a state where it is attached to the first metal fitting 41 so as to be sandwiched between the frame 7 together with the first metal fitting 41. The first coupling part 13 or the second coupling part 14 of the support part 11 is fixed by the first metal fitting 41 and the second metal fitting 46 so as not to move in the horizontal direction relative to the frame 7. For this reason, lateral shaking (horizontal shaking) of the support part 11 is suppressed.

[0078] <Fourth embodiment> A support member 10 according to a fourth embodiment will be described with reference to Fig. 7. In this embodiment, configurations common to the first embodiment are given the same reference numerals as the configurations of the first embodiment, and descriptions of overlapping configurations will be omitted.

[0079] In this embodiment, the support portion 11 of the support member 10 includes a horizontal bar 30, a first vertical bar 31 connected to the horizontal bar 30, and a second vertical bar 32 connected to the horizontal bar 30, as in the first embodiment. In this embodiment, the first vertical bar 31 and the second vertical bar 32 are fixed to the horizontal bar 30 so as to be rotatable about a line along the up-down direction. The first vertical bar 31 and the second vertical bar 32 are fixed to the horizontal bar 30 at a predetermined angle by a bolt. The predetermined angle is defined as the angle between a line along the width direction of the first vertical bar 31 and the second vertical bar 32 and a line along the longitudinal direction of the horizontal bar 30. The predetermined angle is 0 degrees or 90 degrees. The predetermined angle may be a predetermined angle in the range of 0 degrees to 180 degrees.

[0080] 7, the first vertical bar 31 and the second vertical bar 32 are fixed to the horizontal bar 30 at 0 degrees. According to the support member 10 of this example, the support member 10 can be fixed to the frame 7 that is arranged parallel to the horizontal bar 30 in a plan view.

[0081] The first vertical bar 31 and the second vertical bar 32 are rotatably fixed to the horizontal bar 30, so that the support member 10 can be fixed in various orientations relative to the frame 7. For example, the support member 10 can be fixed to the frame 7 parallel to the horizontal bar 30 (see FIG. 9). The support member 10 can also be fixed to the frame 7 perpendicular to the horizontal bar 30 in a plan view (see FIG. 12). When the specified angle is 45 degrees, the support member 10 can be fixed to the frame 7 intersecting the horizontal bar 30 at 45 degrees or 135 degrees in a plan view. In this way, the support member 10 can be fixed at various angles relative to the frame 7 of the ceiling substrate 6 in a plan view. This increases the degree of freedom in arranging the air-conditioning-related items 1 relative to the frame 7 of the ceiling substrate 6.

[0082] <Fifth embodiment> A support member 10 according to a fifth embodiment will be described with reference to Fig. 8. In this embodiment, configurations common to the first embodiment are given the same reference numerals as the configurations of the first embodiment, and descriptions of overlapping configurations will be omitted.

[0083] The support member 10 further includes a connecting portion 33 in addition to the support portion 11 . The connecting portion 33 reinforces the support portion 11. The connecting portion 33 is configured to connect a predetermined portion to another predetermined portion in the support portion 11. Hereinafter, a specific example of the support member 10 according to this embodiment will be described.

[0084] The support part 11 includes a horizontal bar 30, a first vertical bar 31 connected to the horizontal bar 30, and a second vertical bar 32 connected to the horizontal bar 30. The connecting part 33 is configured as a bar extending parallel to the horizontal bar 30. The connecting part 33 is configured to connect the first vertical bar 31 and the second vertical bar 32. The support part 11 and the connecting part 33 form a frame. This improves the strength of the support member 10. Such a support member 10 is suitable for use in supporting air-conditioning-related equipment 3.

[0085] Sixth embodiment A support structure for an air-conditioning-related item 1 according to a sixth embodiment will be described with reference to Fig. 9. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0088] The first connecting portion 13 and the second connecting portion 14 of the support member 10 are connected to the ceiling substrate 6 so that the duct 2A is disposed below the support member 10.

[0089] Furthermore, the duct 2A is suspended from the support portion 11 so that a gap is provided between the duct 2A and the ceiling substrate 6.

[0090] [effect] (1) According to this support structure for air-conditioning-related items 1, duct 2A can be easily disposed at a predetermined height relative to ceiling substrate 6. Furthermore, duct 2A is disposed at a predetermined height relative to ceiling substrate 6 without contacting ceiling substrate 6. This suppresses deterioration of duct 2A.

[0091] (2) In addition, the air conditioning piping-related object 2 is suspended from the support portion 11 so that a gap is provided between the air conditioning piping-related object 2 and the ceiling substrate 6. Therefore, the air conditioning piping-related object 2 is disposed at a predetermined height relative to the ceiling substrate 6 without contacting the ceiling substrate 6. This prevents deterioration of the air conditioning piping-related object 2.

[0092] Seventh embodiment A support structure for an air-conditioning-related item 1 according to the seventh embodiment will be described with reference to Fig. 10.

[0123] The first connecting portion 13 and the second connecting portion 14 of the support member 10 are connected to the ceiling substrate 6 such that the refrigerant piping 2C is disposed below the support member 10. Furthermore, the refrigerant piping 2C is suspended from the support portion 11 such that a gap is provided between the refrigerant piping 2C and the ceiling substrate 6.

[0124] According to this configuration, the refrigerant pipes 2C can be easily arranged at a predetermined height position relative to the ceiling substrate 6. Furthermore, the refrigerant pipes 2C are arranged at a predetermined height position relative to the ceiling substrate 6 without contacting the ceiling substrate 6. This suppresses deterioration of the refrigerant pipes 2C.

[0125] <Thirteenth embodiment> 16 to 19, a support structure for an air-conditioning-related item 1 according to a thirteenth embodiment will be described.

According to this configuration, the air conditioner 3A can be easily disposed at a predetermined height relative to the ceiling substrate 6.

[0129] [First example of a connection structure using connecting members] With reference to FIG. 17, the support member 10 and the connecting structure including the connecting member 25 will be described. The support member 10 has a structure similar to that of the support member 10 of the first embodiment (see FIG. 1). The support member 10 further has a support joint portion 15. The support joint portion 15 is a portion that is joined to a joining bolt 26 (e.g., a hanging bolt) serving as a connecting member 25. The support joint portion 15 may be the fixing hole 11C described above.

[0130] The air conditioner 3A has a first fixed portion 3C and a second fixed portion 3D provided above the first fixed portion 3C. The connecting member 25 includes a connecting bolt 26 and a connecting fitting 27. An upper portion of the connecting bolt 26 is fixed to the support joint portion 15 of the support portion 11 of the support member 10. An intermediate portion of the connecting bolt 26 is inserted into a hole of the second fixing portion 3D. A lower portion of the connecting bolt 26 is fixed to the first fixing portion 3C provided on the air conditioner 3A.

[0131] The connecting fitting 27 is made of sheet metal. The connecting fitting 27 has an upper end fixing portion 27A and a lower end fixing portion 27B located below the upper end fixing portion 27A. The upper end fixing portion 27A of the connecting fitting 27 is fixed to the second fixing portion 3D of the air conditioner 3A while engaging with the middle portion of the connecting bolt 26. The lower end fixing portion 27B of the connecting fitting 27 is fixed to the first fixing portion 3C of the air conditioner 3A while engaging with the lower portion of the connecting bolt 26.

[0132] Thus, the support structure for air-conditioning-related items 1 including the first example connecting structure is provided with a connecting member 25 that connects the air conditioner 3A to the support member 10. The connecting member 25 has a connecting bolt 26 (suspension bolt). The air conditioner 3A has a first fixing portion 3C that connects to the connecting bolt 26, and a second fixing portion 3D that connects to the connecting bolt 26. The second fixing portion 3D connects to a portion of the suspension bolt different from the portion to which the first fixing portion 3C is connected. The first fixing portion 3C is connected to the suspension bolt so that its position can be adjusted.

[0133] According to this configuration, the position of the air conditioner 3A relative to the support member 10 can be adjusted by changing the connection position between the connecting bolt 26 and the air conditioner 3A.

[0134] Furthermore, because the air conditioner 3A is connected to the connecting bolts 26 (suspension bolts) at two points, the air conditioning-related equipment 3 is less likely to shake relative to the connecting bolts 26. This makes it possible to suitably suppress shaking of the air conditioning-related equipment 3 relative to the support member 10. Furthermore, the first fixed portion 3C and the second fixed portion 3D of the air conditioner 3A are connected by a connecting fitting 27. This reinforces the first fixed portion 3C and the second fixed portion 3D of the air conditioner 3A.

[0135] [Second example of a connection structure using connecting members] With reference to FIG. 18, the support member 10 and the connecting structure including the connecting member 25 will be described. In this example, the support member 10 has the structure of the first embodiment. The air conditioner 3A has a first fixing portion 3C. The connecting member 25 includes a connecting bolt 26. An upper portion of the connecting bolt 26 is fixed to the support connecting portion 15 in the support portion 11 of the support member 10. A lower portion of the connecting bolt 26 is fixed to the first fixing portion 3C provided on the air conditioner 3A.

[0136] The support structure for air-conditioning-related items 1 including the second example connecting structure has a connecting member 25 that connects air-conditioning-related equipment 3 to the support member 10. The connecting member 25 has a connecting bolt 26 (suspension bolt). The air-conditioning-related equipment 3 has a first fixing portion 3C that connects to the connecting bolt 26. The first fixing portion 3C is connected to the connecting bolt 26 so that its position can be adjusted. Therefore, the position of the air-conditioning-related equipment 3 relative to the support member 10 can be adjusted.

[0137] [Effect] In the support structure for the air-conditioning-related item 1, the first connecting portion 13 is connected to the hanging bolt in a position adjustable manner, so that the position of the air-conditioning-related equipment 3 relative to the support member 10 can be adjusted.

[0138] [Third example of a connection structure using connecting members] 16 and 19, the support member 10 and the connecting structure including the connecting member 25 will be described.

[0139] In this example, the support member 10 has the structure of the fifth embodiment (see FIG. 8). That is, the support member 10 has a connecting portion 33. The air conditioner 3A has a second fixing portion 3D and a first fixing portion 3C provided below the second fixing portion 3D.

[0140] The connecting member 25 includes a connecting fitting 27. The connecting fitting 27 is made of sheet metal. The connecting fitting 27 has an upper end fixing portion 27A and a lower end fixing portion 27B located below the upper end fixing portion 27A. The upper end fixing portion 27A of the connecting fitting 27 is arranged so as to overlap the second fixing portion 3D of the air conditioner 3A or the connecting portion 33 of the support member 10. The upper end fixing portion 27A of the connecting fitting 27, the second fixing portion 3D of the air conditioner 3A, and the connecting portion 33 of the support member 10 are fixed to each other by bolts and nuts. The lower end fixing portion 27B of the connecting fitting 27 is fixed to the first fixing portion 3C of the air conditioner 3A.

[0141] In the support structure for air-conditioning-related items 1 including the connecting structure of the third example, the support member 10 has a connecting portion 33 to which the air-conditioning-related equipment 3 is connected. An air conditioner 3A as the air-conditioning-related equipment 3 is connected to the connecting portion 33. Furthermore, the connection between the air conditioner 3A and the support member 10 is reinforced by a connecting fitting 27.

[0142] [Effect] In the support structure for air-conditioning-related items 1, a connecting portion 33 is provided on support member 10. Air conditioner 3A is connected to connecting portion 33. This reinforces support member 10 and allows air conditioner 3A to be joined to connecting portion 33 of support member 10. Furthermore, because the connection between air conditioner 3A and support member 10 is reinforced by connecting fitting 27, shaking of air conditioner 3A can be suppressed when the building shakes due to an earthquake.

[0143] <Fourteenth embodiment> A support structure for an air-conditioning-related item 1 according to a fourteenth embodiment will be described with reference to Fig. 20. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0144] The support structure for the air-conditioning-related equipment 1 includes a chamber 2B, a duct 2A, a refrigerant piping 2C, an air conditioner 3A, and a support member 10 that supports these. The chamber 2B, the duct 2A, and the refrigerant piping 2C are supported by the support member 10. The air conditioner 3A is suspended from the architectural structure 5 by a wire 35.

[0145] [effect] With this configuration, construction can be made more efficient than if all of the air conditioning-related items 1 were hung by wires 35.

[0146] <Fifteenth embodiment> 21 to 23, a method for installing the air-conditioning-related item 1 will be described. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0147] [Installation method for air conditioning piping] In the installation method for the air-conditioning-related item 1, the air-conditioning-related item 1 is attached to a ceiling base 6 by a support member 10. The installation method for the air-conditioning-related item 1 includes a first step and a second step. The first step and the second step are performed after the first preparation step and the second preparation step. In a first example of this embodiment, the air-conditioning-related item 1 is an air-conditioning piping-related item 2. An example of the air-conditioning piping-related item 2 is a duct 2A.

[0148] 21, in a first preparation step, a hanging member 20 is attached to a duct 2A in advance. Then, the duct 2A is placed on a ceiling substrate 6. Then, the duct 2A is placed so as to follow a preset arrangement line.

[0149] 22, in the second preparation step, the support member 10 is placed at a predetermined position with respect to the duct 2A. The installation position of the support member 10 on the ceiling foundation 6 may be set in advance, or may be appropriately set on-site.

[0150] As shown in FIG. 23, in the first step, the duct 2A is attached to the support member 10. For example, the duct 2A is suspended from the support portion 11 of the support member 10 by the first hanging member 21. Then, the height of the duct 2A from the ceiling substrate 6 in the vertical direction is adjusted by adjusting the connection point between the connection bolt 20A of the first hanging member 21 and the support portion 11 in the longitudinal direction of the connection bolt 20A. This adjustment allows the duct 2A to be easily positioned at a predetermined height relative to the ceiling substrate 6. If the predetermined height is set in advance, the connection point may be marked on the connection bolt 20A. Next, in the second step, the first connection portion 13 and the second connection portion 14 of the support member 10 are connected to the ceiling substrate 6. Specifically, the first connection portion 13 and the second connection portion 14 are connected to the frame 7.

[0151] [Effects] According to this construction method, the air conditioning piping-related items 2 can be easily arranged at a predetermined height in the ceiling space. Then, the air conditioning piping-related items 2 can be attached to the ceiling substrate 6 via the support members 10.

[0152] [Installation method for air conditioning related equipment] The installation method of the air conditioning-related equipment 3 is similar to the installation method of the air conditioning piping-related items 2. The installation method of the air conditioning-related equipment 3 includes a first step and a second step. In the first step, the air conditioning-related equipment 3 is attached to the support member 10. In the second step, the first joint portion 13 and the second joint portion 14 of the support member 10 are joined to the ceiling base 6.

[0153] [Effects] According to this construction method, the air conditioning-related equipment 3 can be easily arranged at a predetermined height. And the air conditioning piping-related items 2 can be attached to the ceiling substrate 6 via the support members 10.

[0154] <16th embodiment> 24 to 26, a method for installing the air-conditioning-related item 1 will be described. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0155] In the installation method for the air-conditioning-related item 1, the air-conditioning-related item 1 is attached to a ceiling substrate 6 by a support member 10. The installation method for the air-conditioning-related item 1 includes a first step to a fourth step. In this embodiment, the air-conditioning-related item 1 is an air-conditioning piping-related item 2. An example of the air-conditioning piping-related item 2 is a duct 2A.

[0156] As shown in Fig. 24, in the first step, an end of a wire 35 is fixed to an architectural structure 5 (e.g., a slab). Specifically, an anchor is driven into the underside of the slab. The upper end of the wire 35 is fixed to the anchor in the slab. The wire 35 is hung down from the slab to the floor surface. This makes it possible to perform installation work for air conditioning piping-related items 2 (e.g., duct 2A) on the floor below the slab.

[0157] The wire engaging portion 36 is attached to the wire 35 in advance. When attaching the wire 35 to the slab, the wire 35 is attached to the slab as follows. The wire 35 is attached to the slab so that the direction in which the wire engaging portion 36 can move in the engaged state is upward. The wire engaging portion 36 is disposed on the wire 35 at a position close to the floor surface. When adjusting the position of the wire engaging portion 36 relative to the wire 35, the wire engaging portion 36 can be moved downward relative to the wire 35 by switching the state of the wire engaging portion 36 to a released state. Then, the support member 10 is attached to the wire engaging portion 36. As a result, the support member 10 is movably attached to the wire 35 via the wire engaging portion 36.

[0158] 25, in the second step, an air conditioning piping-related item 2 (e.g., a duct 2A) is attached to the support member 10 that engages with the wire 35. For example, the air conditioning piping-related item 2 is attached to the support part 11 of the support member 10 by a first hanging member 21. The method of attaching the first hanging member 21 to the support part 11 of the support member 10 conforms to the method of the fifteenth embodiment.

[0159] 26, in the third step, the support member 10 is placed in a predetermined position by moving the support member 10 relative to the wire 35. Specifically, the support member 10 and the air conditioning piping-related item 2 are placed in a predetermined position higher than the ceiling substrate 6 by moving the wire engaging portion 36 upward relative to the wire 35 while maintaining the wire engaging portion 36 in an engaged state. Because the wire engaging portion 36 is in an engaged state, the support member 10 and the air conditioning piping-related item 2 will not fall even if the worker releases their hands from these items when moving the support member 10 and the air conditioning piping-related item 2 upward.

[0160] In a fourth step, the first connecting portion 13 and the second connecting portion 14 of the support member 10 are connected to the ceiling substrate 6. Specifically, the first connecting portion 13 and the second connecting portion 14 are connected to the frame 7.

[0161] According to this configuration, the air conditioning piping-related item 2 can be easily positioned at a predetermined height by moving the support member 10 relative to the wire 35. Then, the air conditioning piping-related item 2 can be attached to the ceiling foundation 6 via the support member 10.

[0162] <Seventeenth embodiment> 27 to 29, a method for installing the air-conditioning-related item 1 will be described. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0163] In the installation method for the air-conditioning-related item 1, the air-conditioning-related item 1 is attached to a ceiling substrate 6 by a support member 10. The installation method for the air-conditioning-related item 1 includes a first step to a fifth step. In this embodiment, the air-conditioning-related item 1 is an air-conditioning piping-related item 2. An example of the air-conditioning piping-related item 2 is a duct 2A.

[0164] 27, in the first step, the end of the wire 35 is fixed to the architectural structural body 5 (for example, a slab). The method for fixing the end of the wire 35 to the architectural structural body 5 is similar to the second step of the sixteenth embodiment.

[0165] 28, in the second step, the air conditioning piping-related item 2 is attached to the support member 10. The method of attaching the air conditioning piping-related item 2 to the support member 10 is similar to the method of attaching the air conditioning piping-related item 2 to the support member 10 in the sixteenth embodiment.

[0166] 29, in a third step, an air-conditioning piping-related item 2 (e.g., a duct 2A) is engaged with a wire 35. For example, the air-conditioning piping-related item 2 is attached to the wire 35 by a first hanging member 21. Specifically, with a band 21A of the first hanging member 21 wrapped around the duct 2A, a connecting bolt 20A of the first hanging member 21 is attached to a wire engaging portion 36.

[0167] Then, in a fourth step, the air conditioning piping-related object 2 is placed at a predetermined position by moving the air conditioning piping-related object 2 relative to the wire 35. The method of moving the air conditioning piping-related object 2 conforms to the third step of the sixteenth embodiment.

[0168] Furthermore, in a fifth step, the first connecting portion 13 and the second connecting portion 14 of the support member 10 are connected to the ceiling substrate 6. Specifically, the first connecting portion 13 and the second connecting portion 14 are connected to the frame 7.

[0169] According to this configuration, the air conditioning piping-related item 2 can be easily positioned at a predetermined height by moving the air conditioning piping-related item 2 relative to the wire 35. Then, the air conditioning piping-related item 2 can be attached to the ceiling foundation 6 via the support member 10.

[0170] <Modification> In addition to the above-described embodiments, the support member 10, the support structure for the air-conditioning-related item 1, and the installation method for the air-conditioning-related item 1 of the present disclosure may also be configured in a form that combines, for example, the modified examples shown below, or at least two modified examples that are not mutually contradictory.

[0171] The shape of the support member 10 is not limited to the example of the embodiment. The support portion 11 of the support member 10 may be configured in an arc shape. The horizontal bar 30 may be curved. The shapes of the first vertical bar 31 and the second vertical bar 32 are not limited. The first vertical bar 31 and the second vertical bar 32 may be configured from a plate material. The horizontal bar 30, the first vertical bar 31 and the second vertical bar 32 may be configured as cylindrical members.

[0172] The multiple support members 10 may be connected to each other. For example, in the sixteenth embodiment, the two support members 10 supporting the air conditioner 3A may be connected by a connecting bar. This makes it possible to suppress the shaking of the air conditioner 3A when the building shakes due to an earthquake. Similarly, the multiple support members 10 supporting the duct 2A may be connected to each other. This makes it possible to suppress the shaking of the duct 2A when the building shakes due to an earthquake.

[0173] The means for fastening the air conditioning-related item 1 to the support member 10 is not limited to the example given in the first embodiment. As a means for fastening the air conditioning-related item 1 to the support member 10, commercially available metal fittings may be used.

[0174] 19, the air-conditioning-related equipment 3 is fixed to the connecting portion 33 of the support member 10 by a connecting fitting 27 serving as the connecting member 25. Alternatively, the air-conditioning-related equipment 3 may be fixed to the connecting portion 33 of the support member 10 by a connecting bolt 20A (hanging bolt) serving as the connecting member 25.

[0175] The above describes embodiments and their variations of the support member 10, the support structure for the air-conditioning-related item 1, and the installation method for the air-conditioning-related item 1. However, it will be understood that various modifications in form and details are possible without departing from the spirit and scope of the support member 10, the support structure for the air-conditioning-related item 1, and the installation method for the air-conditioning-related item 1 as described in the claims.
