Description

[Technical Field]

[0001] The technology disclosed in this application relates to a mount. [Background technology]

[0002] Patent Document 1 describes a hot water storage tank unit in which one or more hot water storage tanks and a piping unit are integrally arranged and fixed to a hot water storage tank stand. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-108734 Summary of the Invention [Problem to be solved by the invention]

[0004] Various types of equipment are installed in designated equipment rooms in buildings. For example, a pipe space (hereinafter abbreviated as "PS") in an apartment building may be used as an equipment room, and various types of equipment such as a fuel cell unit, a hot water storage unit, and a backup heat source may be installed in this PS. These devices have piping that protrudes from the door side of the equipment room (hereinafter referred to as "door-side piping"), and this door-side piping may pass through a through-hole in the PS door and lead to the outside of the PS. In other words, the through-hole in the PS door is formed to match the height position of the door-side piping from the equipment (height from the PS floor).

[0005] In the configuration in which a hot water storage tank is installed on a hot water storage tank stand described in Patent Document 1, when the hot water storage tank is replaced, the height position of the door-side piping of the replaced equipment may not match the height position of the through-hole formed to match the hot water storage tank before replacement. In this case, forming a new through-hole in the PS door increases the number of work steps and reduces workability.

[0006] This type of issue can arise not only in hot water tanks installed within PSs, but also in various types of equipment installed in equipment rooms when replacing them.

[0007] In consideration of the above, an object of the present invention is to improve the workability when replacing equipment in an equipment room of a building. [Means for solving the problem]

[0008] The first type of stand is a stand that supports equipment placed in an equipment room of a building, and its height is set so that the height position of the piping protruding from the equipment toward the door of the equipment room matches the height position of the through hole in the door.

[0009] Therefore, when replacing equipment, the height position of the door-side piping of the replaced equipment matches the through-hole formed in the equipment room door. This through-hole was formed in the door to match the height position of the door-side piping of the equipment before replacement. Since there is no need to re-form the through-hole in the equipment room door to match the door-side piping of the replaced equipment or to eliminate the height difference, workability is improved when replacing equipment within the equipment room of a building.

[0010] In the second aspect, the stand body has a hollow interior, a top opening formed on the top surface that is located on the upper side when the stand body is installed in the equipment room and that is continuous with the hollow interior, and a front opening formed on the front surface that is located on the door side when the stand body is installed in the equipment room and that is continuous with the hollow interior.

[0011] Since the top opening is continuous with the hollow portion of the gantry body, various pipes and wires extending downward from the equipment installed on the gantry body can be placed in the hollow portion through the top opening. Also, since the front opening is continuous with the hollow portion, tools can be inserted into the hollow portion through the front opening to perform various operations on the various pipes and wires within the hollow portion. In this way, the workability of the various pipes and wires extending downward from the equipment is improved.

[0012] In a third aspect, the top opening and the front opening are continuous.

[0013] This makes the hollow portion easier to see and improves workability compared to a structure in which the top opening and the front opening are not continuous (there are other components between the top opening and the front opening).

[0014] Furthermore, for example, various pipes and wires extending forward from the hollow portion through the front opening can be deformed (by adjusting the degree of bending so that they stand up) while still protruding outside the gantry body without being retracted into the hollow portion, i.e., inside the gantry body, so that they can pass through the top opening. Since there is no need to retract the various pipes and wires into the hollow portion when erecting them, workability is improved.

[0015] In a fourth aspect, the front opening extends to the lower end of the front surface.

[0016] Therefore, compared to a configuration in which the front opening does not reach the lower end of the front surface, the front opening is wider downward, making it easier to see the hollow portion and improving workability.

[0017] In addition, the workability of various operations performed by inserting tools or the like into the hollow portion through the front opening is improved.

[0018] In the fifth aspect, the stand body has a bottom opening formed on the bottom surface located on the lower side when installed in the equipment room, the bottom opening being continuous with the hollow portion, a rear opening formed on the rear surface located on the opposite side of the door when installed in the equipment room, the rear opening being continuous with the hollow portion, and a side opening formed on a side surface located to the side when installed in the equipment room, the side opening being continuous with the hollow portion.

[0019] The hollow section of the stand body is connected to a bottom opening, a rear opening, and a side opening, so that tools can be inserted into the hollow section through these openings to perform various operations on the various pipes and wiring within the hollow section, improving workability.

[0020] In a sixth aspect, the device has a fixing portion for fixing the device to the stand.

[0021] The fixing part can be used to fix the device to the stand.

[0022] In a seventh aspect, the apparatus has a fixed portion for fixing the stand to the equipment room.

[0023] The mount can be fixed to the equipment room using the fixed part.

[0024] In an eighth aspect, the gantry body has, on its upper surface located on the upper side when installed in the equipment room, a guide member for positioning the equipment in the width direction of the gantry body and for guiding movement in the depth direction.

[0025] The guide members allow the device to be positioned in the width direction on the top surface of the stand body, and when the device is pushed to the back, it is guided without any unintentional movement or meandering in the width direction, making the installation of the device easier. [Effects of the Invention]

[0026] In the present application, the workability when replacing equipment in the equipment room of a building is improved. [Brief explanation of the drawings]

[0028] Hereinafter, an example of an embodiment of the present application will be described in detail with reference to the drawings.

[0029] 1 and 2 show an example in which a fuel cell unit 20 is installed in a PS 12 of an apartment building using the mount 22 of the first embodiment. Also, FIGS. 3 to 8 show the mount 22 and a guide member 34. The apartment building is an example of a building, the PS 12 is an example of an equipment room, and the fuel cell unit 20 is an example of equipment.

[0030] The PS 12 is a space in an apartment building that houses various pipes and wiring, such as water supply and sewerage pipes and gas pipes. In this embodiment, the PS 12 houses the fuel cell unit 20 (see FIG. 2), and can also house a hot water storage unit and a backup heat source. For example, when a so-called cogeneration system is configured with the fuel cell unit 20, the hot water storage unit, and the backup heat source, the fuel cell unit 20, the hot water storage unit, and the backup heat source are often installed integrally within the PS 12. The hot water storage unit and the backup heat source can also be installed within the PS 12 using a stand 22. In this case, the hot water storage unit and the backup heat source are examples of equipment in the technology disclosed in the present application.

[0031] 1 and 2, the PS 12 is provided with a door 14. In this embodiment, it has a right door 14R and a left door 14L that can be rotated by hinges. In the illustrated example, a fuel cell unit 20 is disposed in the area corresponding to the right door 14R, and a hot water storage unit and a backup heat source (not shown) are disposed in the area corresponding to the left door 14L.

[0032] As shown in Fig. 2, a base 16 is installed inside the PS 12. In this embodiment, the base 16 is fixed inside the PS and essentially forms part of the PS 12. A fuel cell unit 20 is supported on the base 16 by a stand 22 and installed inside the PS 12.

[0033] The fuel cell unit 20 has a support leg 20L at its bottom. In the example shown in Fig. 2, the support leg 20L is formed in the shape of a rectangular frame when viewed from the front. The support leg 20L is installed on an upper surface 22UP of the stand 22, as will be described later.

[0034] The fuel cell unit 20 is provided with an exhaust pipe 20P that protrudes toward the closed door 14. The exhaust pipe 20P is an example of a door-side pipe in the technology disclosed in the present application.

[0035] A through-hole 14H is formed in the right door 14R. The through-hole 14H is an opening through which the exhaust pipe 20P passes when the right door 14R is closed. That is, even when the right door 14R is closed, the tip of the exhaust pipe 20P protrudes outside the PS 12.

[0036] The fuel cell unit 20 shown in Figure 2 has replaced the fuel cell unit originally installed in the PS 12. The replaced fuel cell unit 20 has a lower height compared to the fuel cell unit before replacement. The height of the exhaust pipe (measured from the bottom end of each unit) of the replaced fuel cell unit 20 is also lower than that of the fuel cell unit before replacement.

[0037] 3 to 8, the mount 22 has a mount main body 22H and a pair of guide members 34. The mount main body 22H is shaped like a rectangular parallelepiped frame overall, and has six sides: an upper side 22UP, a lower side 22DO, a front side 22FR, a rear side 22RR, a right side 22RH, and a left side 22LH. The upper side 22UP also serves as a support surface for supporting the fuel cell unit 20.

[0038] In the drawings, the arrow UP indicates the top of the pedestal 22, the arrow DO indicates the bottom, the arrow RH indicates the right, the arrow LH indicates the left, the arrow FR indicates the front, and the arrow RR indicates the rear. In the technology disclosed in the present application, these directions of the pedestal 22 coincide with the directions of the pedestal main body 22H, the fuel cell unit 20, and the PS12. Note that a symbol with an "x" inside a "circle" in the drawings indicates an arrow pointing from the front to the back of the page. Also, a symbol with a "·" inside a "circle" in the drawings indicates an arrow pointing from the back to the front of the page.

[0039] In the drawings, the external width (external dimension in the left-right direction) of the gantry main body 22H is indicated as W1, the external height (external dimension in the up-down direction) as H1, and the external depth (external dimension in the front-to-back direction) as D1. The external height H1 of the gantry main body 22H is the actual height of the gantry 22 when supporting the fuel cell unit 20. Furthermore, the gantry 22 of this embodiment has the same external width and depth as the gantry main body 22H.

[0040] In the gantry 22 of this embodiment, the six surfaces of the gantry main body 22H can all be formed from metal plates. For example, a single plate can be punched into a predetermined shape (the shape of the developed view), bent at predetermined locations, and assembled to form the rectangular parallelepiped gantry main body 22H having six surfaces. Alternatively, a plurality of plate materials can be joined at predetermined locations to form the rectangular parallelepiped gantry main body 22H having six surfaces.

[0041] The outer width W1 and outer depth D1 of the stand body 22H are sized to be able to support the fuel cell unit 20 on the upper surface 22UP. Specifically, it is sufficient that the outer width W1 and outer depth D1 are longer than the lower part of the fuel cell unit 20, i.e., the support legs 20L which are the parts installed on the upper surface 22UP of the stand body 22H.

[0042] The external height H1 of the stand body 22H is set so that when the fuel cell unit 20 is installed on the upper surface 22UP, the height position of the exhaust pipe 20P coincides with the height position of the through hole 14H in the right door 14R of the PS12.

[0043] Because the gantry 22 has a gantry main body 22H formed in a frame shape as described above, the interior is a hollow portion 24. An opening that continues to the hollow portion 24 is formed on each of the six sides of the gantry 22. Specifically, a front opening 26FR is formed on the front side 22FR, a rear opening 26RR is formed on the rear side 22RR, an upper opening 26UP is formed on the upper side 22UP, a lower opening 26DO is formed on the lower side 22DO, a right side opening 26RH is formed on the right side 22RH, and a left side opening 26LH is formed on the left side 22LH. Hereinafter, when there is no need to distinguish between these six openings, they will be referred to as openings 26.

[0044] All six openings 26 communicate with the hollow portion 24. Therefore, at any of the six openings 26, it is possible to access the hollow portion 24 through the opening 26 from outside the pedestal 22 and insert tools or the like.

[0045] 4, the opening width W2 of the front opening 26FR is narrower than the outer width W1 of the gantry main body 22H, and the opening height H2 of the front opening 26FR is equal to the outer height H1 of the gantry 22. Therefore, the front opening 26FR is located in the center of the front surface 22FR in the width direction, and is formed from the upper end to the lower end in the vertical direction.

[0046] 5, the opening width W3 of the top opening 26UP is narrower than the outer width W1 of the gantry main body 22H and wider than the opening width W2 of the front opening 26FR, but is formed to have an opening width equal to the opening width W2 of the front opening 26FR (and therefore narrower than the opening width W3) on the front and rear sides in the depth direction. Also, the opening depth D3 of the top opening 26UP is shorter than the outer depth D1 of the gantry 22, and in particular, the top opening 26UP is formed up to the front surface 22FR (see FIG. 3).

[0047] In this way, the front opening 26FR is formed up to the upper surface 22UP, and the upper surface opening 26UP is formed up to the front surface 22FR, thereby realizing a shape in which the front opening 26FR and the upper surface opening 26UP are continuous. In other words, there is no part separating the front opening 26FR and the upper surface opening 26UP.

[0048] In the upper surface opening 26UP, portions with an opening width W2 narrower than the opening width W3 are formed on the front and back sides of the portion having the opening W3, thereby forming support regions 28 that are rectangular in plan view at the four corners of the upper surface 22UP. The support regions 28 are portions where the fuel cell unit 20 is supported.

[0049] Each of the support regions 28 has an upper bolt hole 32UP formed therein that penetrates the upper surface 22UP in the plate thickness direction. The upper bolt hole 32UP is an example of a fixing portion. For example, a bolt can be inserted into the upper bolt hole 32UP and screwed into a female thread formed in the fuel cell unit 20, thereby fixing the fuel cell unit 20 to the upper surface 22UP of the frame 22. In this embodiment, the upper bolt hole 32UP is formed as an elongated hole whose longitudinal direction is the depth direction of the frame 22, and the fixing position of the fuel cell unit 20 can be adjusted in the depth direction.

[0050] The central depth portion of the upper surface opening 26UP (portion having opening width W3) is wider than the widthwise spacing L3 between the four upper bolt holes 32UP, and is open wide in the widthwise direction up to the portion between the front and rear upper bolt holes 32UP.

[0051] In addition, the widthwise central portion of the upper surface opening 26UP (the portion having the opening depth D3) is wider than the depthwise spacing L2 between the four upper bolt holes 32UP, and is open to the front and back sides up to the portion between the left and right upper bolt holes 32UP.

[0052] 6, the opening width W4 of the bottom opening 26DO is narrower than the outer width W1 of the gantry main body 22H, and the opening depth D4 is shorter than the outer depth D1 of the gantry main body 22H. The bottom opening 26DO is located at the center of the bottom surface 22DO in the width and depth directions, and a bottom frame region 30DO that is rectangular in plan view is formed around the bottom opening 26DO on the bottom surface 22DO. The bottom frame region 30DO is the portion that comes into contact with the floor surface of the PS 12 when the gantry 22 is installed inside the PS 12.

[0053] In the lower frame region 30DO, lower bolt holes 32DO are formed near the four corners of the lower surface 22DO, penetrating the lower surface 22DO in the plate thickness direction. The lower bolt holes 32DO are an example of a fixed portion. The gantry 22 can be fixed to the floor surface of the PS 12 by inserting a bolt protruding from the floor surface of the PS 12 into the lower bolt hole 32DO and fastening a nut to the bolt. In this embodiment, the lower bolt holes 32DO are formed as elongated holes whose longitudinal direction is the depth direction of the gantry 22, and the fixed position of the gantry 22 can be adjusted in the depth direction.

[0054] 7, the opening width W5 of the rear opening 26RR is narrower than the outer width W1 of the gantry main body 22H, and the opening height H5 is shorter than the outer height H1 of the gantry main body 22H. The rear opening 26RR is located at the center of the rear surface 22RR in the width and height directions, and a rear frame region 30RR that is rectangular in front view is formed around the rear opening 26RR on the rear surface 22RR.

[0055] 8, the opening depth D6 (effectively the opening width) of the right side surface opening 26RH and the left side surface opening 26LH is shorter than the external depth D1 of the gantry main body 22H, and the opening height H6 is shorter than the external height H1 of the gantry main body 22H. The right side surface opening 26RH and the left side surface opening 26LH are located at the centers of the right side surface 22RH and the left side surface 22LH, respectively. A right side surface frame region 30RH is formed around the right side surface opening 26RH in a side view, and a left side surface frame region 30LH is also formed around the left side surface opening 26LH in a side view.

[0056] Although FIG. 8 shows the left side surface 22LH, the same shape also appears symmetrically in the front-rear direction of the pedestal 22 on the right side surface 22RH.

[0057] In this embodiment, the gantry main body 22H has a shape symmetrical with respect to the center line CL in the width direction (strictly speaking, the center plane).

[0058] A pair of guide members 34 are disposed on the upper surface 22UP of the gantry main body 22H. The guide members 34 are shaped and disposed symmetrically on the left and right sides with respect to the center line CL in the width direction of the gantry main body 22H.

[0059] The guide member 34 is an elongated member arranged with its longitudinal direction aligned with the depth direction of the mounting body 22H, and when viewed from the front, has a horizontal plate portion 34H that contacts the upper surface 22UP, and a vertical plate portion 34V that rises upward from the center of the width direction of this horizontal plate portion 34H (the end edge close to the center line CL).

[0060] The guide members 34 are fixed to the upper surface 22UP of the frame body 22H using fasteners (bolts, pins, clips, etc.) or adhesive (not shown). As shown in Figures 4 and 7, the distance W7 between the vertical plate portions 34V of the left and right guide members 34 is equal to or slightly longer than the outer width W11 of the lower end of the fuel cell unit 20 (the portion installed on the frame body 22H).

[0061] At the end of the guide member 34 in the depth direction, a positioning piece 36 located below the horizontal plate portion 34H and a positioning stopper 38 located above the horizontal plate portion 34H are formed.

[0062] When the guide member 34 is placed on the upper surface of the stand 22 and the positioning piece 36 comes into contact with the rear surface 22RR of the stand 22, the guide member 34 cannot move any further forward relative to the stand 22, and the guide member 34 is positioned in the depth direction.

[0063] When the fuel cell unit 20 is placed on the upper surface 22UP of the stand body 22H and comes into contact with the positioning stopper 38, the fuel cell unit 20 cannot move any further rearward relative to the positioning stopper 38. In other words, when the fuel cell unit 20 comes into contact with the positioning stopper 38, the fuel cell unit 20 is positioned in the depth direction.

[0064] Next, the operation of this embodiment will be described.

[0065] A fuel cell unit may be replaced inside the PS 12. A through-hole 14H in a right door 14R of the PS 12 is formed to match the height position of the exhaust pipe of the fuel cell unit before replacement.

[0066] However, in the replaced fuel cell unit 20, the height position of the exhaust pipe 20P may be lower than the height position of the exhaust pipe of the fuel cell unit before replacement, for example, because the external dimension height of the replaced fuel cell unit 20 is lower than that of the fuel cell unit before replacement.

[0067] Therefore, if the replaced fuel cell unit 20 is simply installed inside the PS 12, the exhaust pipe 20P will be located lower than the through-hole 14H of the right door 14R. To bring the exhaust pipe 20P outside the PS 12 requires work such as forming a new through-hole in the right door 14R or adjusting the height of the exhaust pipe 20P, which increases the number of steps and reduces work efficiency.

[0068] In contrast, in the stand 22 of this embodiment, the external dimension height H1 of the stand body 22H is set so that when the replaced fuel cell unit 20 is installed on the upper surface 22UP, the height position of the exhaust pipe 20P matches the height position of the through hole 14H of the right door 14R of the PS12.

[0069] As a result, when the fuel cell unit 20 is installed inside the PS 12 using the stand 22 of this embodiment, the exhaust pipe 20P can be inserted into the through-hole 14H without having to perform tasks such as reforming the through-hole 14H in the right door 14R of the PS 12 or adjusting the height position of the exhaust pipe 20P. Because tasks such as reforming the through-hole 14H and adjusting the height position of the exhaust pipe 20P are not required, workability is improved compared to when these tasks are required.

[0070] A pair of guide members 34 are provided on the upper surface 22UP of the gantry main body 22H. The guide members 34 have positioning pieces 36, which come into contact with the rear surface 22RR of the gantry main body 22H. This positions the guide members 34 in the front-rear direction relative to the gantry main body 22H. Then, in the positioned state, the guide members 34 are fixed to the upper surface 22UP of the gantry main body 22H.

[0071] The distance W7 between the left and right guide members 34 is equal to or slightly longer than the width W11 of the lower end of the fuel cell unit 20. Therefore, the fuel cell unit 20 is positioned in the width direction when it is placed on the upper surface 22UP between the guide members 34. There is no need to align the fuel cell unit 20 in the width direction on the upper surface 22UP of the frame main body 22H, which makes installation easier.

[0072] Then, with the fuel cell unit 20 aligned in the width direction, it can be pushed in towards the rear as shown by arrow A1 in Figure 9. Because the fuel cell unit 20 is guided in the width direction by the guide members 34, it is guided without any unintentional movement or meandering in the width direction when it is pushed in towards the rear, making installation of the fuel cell unit 20 easier.

[0073] The guide member 34 has a positioning stopper 38, and the fuel cell unit 20 is also positioned in the depth direction when it comes into contact with the positioning stopper 38. There is no need to align the fuel cell unit 20 in the depth direction on the upper surface 22UP of the stand main body 22H, and the fuel cell unit 20 can be installed in the specified position by simply pushing it in the depth direction, resulting in excellent workability.

[0074] In particular, in the PS 12, the installation work of the fuel cell unit 20 is performed with the door 14 open. When the installation work is performed from the door 14 side in this way, the fuel cell unit 20 can be aligned in the width direction and depth direction on the upper surface 22UP of the stand main body 22H, improving the workability of the installation work.

[0075] The frame body 22H has support areas 28 formed at the four corners of the upper surface 22UP. Using these support areas 28, the fuel cell unit 20 can be reliably supported.

[0076] 11 and 12, various types of pipes 42 (gas pipes, water supply pipes, hot water storage pipes, etc.) and wiring 44 (power lines, current transformer wiring, communication lines, etc.) are arranged below the fuel cell unit 20. A hollow section 24 is provided in the frame main body 22H, and these pipes 42 and wiring 44 can be arranged in the hollow section 24 through the top surface opening 26UP, allowing various work (such as connecting to other pipes and wiring) to be performed. In this way, the hollow section 24 can be used as a space for arranging the pipes 42 and wiring 44, making it easier to work than a structure without the hollow section 24.

[0077] The gantry body 22H has a plurality of openings 26 (provided on each of six sides in this embodiment). Tools and the like can be inserted into the hollow portion 24 through the openings 26, allowing various operations to be performed in the hollow portion 24, improving workability.

[0078] For example, the hollow portion 24 can be accessed from any of the openings 26, such as the front opening 26FR or the top opening 26UP, to perform the work of fixing the fuel cell unit 20 to the frame 22. In other words, the openings 26 and the hollow portion 24 function as a work space for the work of fixing the fuel cell unit 20.

[0079] In particular, the front opening 26FR is an opening in the front surface 22FR located on the door 14 side of the PS 12. Therefore, as shown in Fig. 2, when the door 14 (the right door 14RF in the example of Fig. 2) is open, access to the hollow portion 24 from the front surface 22FR side is easy, resulting in excellent workability.

[0080] Furthermore, when supporting a fuel cell unit 20 having support legs 20L, for example, the upper surface opening 26UP allows access to the hollow portion 24 from between the support legs 20L through the upper surface opening 26UP, resulting in excellent workability.

[0081] Furthermore, when the fuel cell unit 20 is installed on the right side within the PS 12, a gap may be formed between the fuel cell unit 20 and other equipment installed on the left side (for example, a hot water storage unit or a backup heat source), but this gap allows access to the hollow portion 24 through the left side opening 26LH, improving workability. The frame 22 also has a right side opening 26RH, so when the fuel cell unit 20 is installed on the left side within the PS 12, for example, the hollow portion 24 can be accessed through the gap between the fuel cell unit 20 and other equipment on the right side through the right side opening 26RH.

[0082] Furthermore, depending on the internal dimensions of the PS 12, gaps may occur between the inner surface of the PS 12 and the stand 22. These gaps may allow access to the hollow space 24 through the rear opening 26RR and the right side opening 26RH, and in this case too, using the stand 22 contributes to improving the workability of the cleaning work.

[0083] Of the six openings 26, the front opening 26FR in particular is located in the center in the width direction on the front surface 22FR of the frame 22, and is formed from the top end to the bottom end in the vertical direction. Because the opening height H2 of the front opening 26FR is wide in the vertical direction, it is easy to access the hollow portion 24 from the front surface 22FR side, and workability is high.

[0084] 13, the front opening 26FR and the top opening 26UP are continuous, and there is no part separating them. Therefore, when viewing the hollow portion 24 from outside the pedestal 22, the members between the front opening 26FR and the top opening 26UP do not get in the way, resulting in excellent workability.

[0085] For example, it is possible to erect pipe 42A, with its tip portion protruding from front surface opening 26FR toward front surface 22FR, as shown by arrow A2, so that it passes through upper surface opening 26UP without temporarily retracting (pushing to the back) pipe 42A into hollow portion 24. Since pipe 42A can be erected without retracting into hollow portion 24, this also provides excellent workability.

[0086] The portion of top surface opening 26UP having opening width W3 is wider than the widthwise spacing L3 between four upper bolt holes 32UP. In other words, the opening is wide in the widthwise direction up to the portions between the front and rear upper bolt holes 32UP, which makes it easier to access hollow portion 24 and improves workability compared to a shape that does not open as widely.

[0087] Furthermore, the widthwise central portion of the top surface opening 26UP is wider than the depthwise spacing L2 between the four upper bolt holes 32UP. Because the opening extends to the front and back sides up to the portions between the left and right upper bolt holes 32UP, access to the hollow portion 24 is easier and workability is improved compared to a shape that does not open as widely.

[0088] Although the upper bolt holes 32UP are given above as an example of a fixing portion, the fixing portion is not limited to this. For example, clips, clamps, etc. can also be used as fixing portions. By providing the upper bolt holes 32UP as fixing portions, the fuel cell unit 20 can be fixed to the frame 22 using bolts and nuts, thereby simplifying the fixing structure.

[0089] Similarly, although the lower bolt hole 32DO is given above as an example of a fixed portion, the fixed portion is not limited to this. As with the fixing portion, a clip, a clamp, or the like can also be used as the fixed portion. By providing the lower bolt hole 32DO as the fixed portion, the mount 22 can be fixed to the PS 12 using a bolt and nut, thereby simplifying the fixing structure.

[0090] Although the shape of the gantry main body 22H formed in the shape of a rectangular parallelepiped frame has been described above, the shape is not limited to this. For example, the gantry main body may have a shape other than a rectangle in a plan view (as viewed from above).

[0091] Furthermore, the mount may include an upper frame member and a lower frame member that are connected so as to be movable together, thereby making the mount height adjustable. For example, by placing an angle member having a vertically elongated hole between the upper and lower frame members and inserting a bolt into the elongated hole and fastening a nut, a mount structure whose height is adjustable within the range of the length of the elongated hole can be realized.

[0092] Furthermore, the mount 22 may be provided with holes or hooks for fastening devices (cable ties, rubber ties, etc.) for fastening various types of pipes and wiring to the mount 22. Fastening the pipes and wiring to the mount 22 with fastening devices can prevent the pipes and wiring from flapping and can maintain them in a predetermined position, resulting in excellent workability.

[0093] The equipment supported by the stand 22 is not limited to the fuel cell unit 20 described above. For example, it may be a hot water storage unit or a backup heat source that constitutes a cogeneration system similar to the fuel cell unit 20. Furthermore, if the equipment has door-side piping facing the outside of the PS 12, it is possible that the position of the through-hole 14H (see FIGS. 1 and 2) does not match the door-side piping of the replaced equipment. In such a case, by using the stand 22 of the technology disclosed in the present application, the height position of the door-side piping of the replaced equipment can be made to match the height position of the through-hole 14H without performing any special work, thereby improving workability.

[0094] The space for installing the equipment is not limited to the PS described above, and may be any equipment room in a building that is provided to accommodate various types of equipment.

[0095] The building in which the equipment is placed in the equipment room is not limited to the above-mentioned apartment building, but may also be an office building, a commercial facility, a factory, or the like. [Explanation of symbols]
