Description

The present invention relates to a steady rest device for steadying a ceiling suspended object such as an air conditioner installed in a ceiling space.

BACKGROUND ART Conventionally, air conditioners installed in a suspended state in a ceiling space are known (for example, Patent Documents 1 and 2). This air conditioner has a generally rectangular shape in plan view, and includes a pair of mounting pieces for connecting bolt members such as hanging bolts near the bottoms of two mutually parallel side surfaces. When installing such an air conditioner in a ceiling space, the lower ends of bolt members hanging from a ceiling structure such as a ceiling slab are connected to a pair of mounting pieces provided on each of the two sides. . That is, the concealed air conditioner is installed in a ceiling space with the lower portions of two mutually parallel sides supported by a total of four bolt members.

FIG. 11 is a diagram showing a conventional support structure 200 with an air conditioner 300 installed in a ceiling space. As shown in FIG. 11, in the conventional support structure 200, a bolt member 209 such as a hanging bolt is suspended from a ceiling structure 8 such as a ceiling slab, and the air conditioner 300 is supported at the lower end of the bolt member 209. It is a structure. The air conditioner 300 includes a pair of attachment pieces 311, 311 for connecting the bolt member 209 near the lower part of the side surface, and the lower end of the bolt member 209 is connected to the pair of attachment pieces 311, 311. Ru. Thereby, the air conditioner 300 is supported in a suspended state in the ceiling space.

When the air conditioner 300 is installed in a suspended state by the bolt members 209, a brace 213 for resting the air conditioner 300 is attached to the bolt members 209. The brace 213 is arranged diagonally to connect two bolt members 209 adjacent to each other, and connects and fixes the upper part of one bolt member 209 and the lower part of the other bolt member 209. By intersecting the two braces 213 between the two adjacent bolt members 209, 209, the bolt members 209, 209 are fixed, and the air conditioner 300 can be stopped from swinging.

However, the conventional support structure 200 described above has a structure in which the brace 213 is connected to the bolt members 209, 209 at a position higher than the top surface of the air conditioner 300. Therefore, the anti-sway effect of the brace 213 cannot be obtained at the lower part of the bolt members 209, 209 (region R shown in FIG. 11). As a result, there is a problem in that when an earthquake occurs, the lower portions of the bolt members 209, 209 vibrate, and the air conditioner 300 also vibrates accordingly.

In addition, in this type of air conditioner 300, refrigerant pipes, air ducts, etc. are connected to the main body of the device, so if the main body of the device vibrates, these connections will be damaged, and even after the earthquake has subsided, There is also the problem of not being able to operate normally.

The present invention has been made to solve the above-mentioned problems, and it fixes bolt members that support ceiling-suspended objects such as air conditioners, and improves the effect of preventing the ceiling-suspended objects from swinging compared to conventional methods. It is an object of the present invention to provide a steady rest device that can be used effectively.

(First embodiment)
FIG. 1 is a perspective view showing a support structure for a ceiling suspended object including a steady rest device 1 according to a first embodiment of the present invention. The XYZ three-dimensional coordinate system shown in FIG. 1 is a coordinate system in which the XY plane is a horizontal plane and the Z direction is a vertical direction, and is a coordinate system common to other figures. The steady rest device 1 of this embodiment is a device that fixes the lower part of a bolt member 9 that supports a ceiling suspended object in a suspended state in a ceiling space, and prevents the ceiling suspended object from steadying. In this embodiment, a concealed air conditioner 100 is illustrated as an object suspended from the ceiling. This air conditioner 100 is installed in a hidden state in a ceiling space between a ceiling structure such as a ceiling slab and a ceiling panel.

The air conditioner 100 is a generally rectangular box-shaped unit in a plan view that includes a heat exchanger therein, and has four side surfaces 110a, 110b, 110c, and 110d around the unit. For example, the side surface 110a is provided with a connection portion for connecting a refrigerant pipe or the like. A pair of attachment pieces 111, 111 for connecting the lower end portions of the bolt member 9 are provided at predetermined positions below both ends of the side surface 110a. Furthermore, a pair of attachment pieces 111, 111 are similarly provided on a side surface 110b, which is located on the opposite side of the side surface 110a and is parallel to the side surface 110a, at predetermined positions at the bottom of both ends. The remaining two side surfaces 110c and 110d are connected to both ends of these two side surfaces 110a and 110b. The side surface 110c is provided with an outlet 118 for blowing out the heat-exchanged air, and the side surface 110d is provided with an intake port (not shown) for guiding the air to the internal heat exchanger. That is, this air conditioner 100 is configured to suck in air from an intake port provided on a side surface 110d, and blow out heat-exchanged air from an air outlet 118 provided on a side surface 110c. Note that a blow-off unit (not shown) can be connected to the blow-off port on the side surface 110c, and an air intake unit (not shown) can be connected to the suction port on the side surface 110d.

In this air conditioner 100, the lower ends of four bolt members 9 hanging in the ceiling space are connected to a pair of mounting pieces 111, 111 provided on two mutually parallel side surfaces 110a, 110b, respectively. As a result, it is supported in a suspended state in the ceiling space. These pair of attachment pieces 111, 111 are provided at the lower part of the side surfaces 110a, 110b of the air conditioner 100 at a predetermined interval in the horizontal direction (Y direction). Each mounting piece 111 has an insertion portion cut out in, for example, a U-shape, and the bolt member 9 can be inserted into the insertion portion. Then, with the two nuts 151 and 152 attached to the bolt member 9, the lower end of the bolt member 9 is inserted into the insertion portion of the mounting piece 111, and the mounting piece 111 is sandwiched between the two nuts 151 and 152, so that the bolt member A lower end portion of 9 is connected to a mounting piece 111. By connecting the lower ends of the bolt members 9 to each attachment piece 111 in this manner, the air conditioner 100 is in a state where it is supported by the four bolt members 9.

In the steady rest device 1 of this embodiment, the bolt member 9 connected to the mounting pieces 111 provided on the side surfaces 110a and 110b of the air conditioner 100 as described above is attached to the air conditioner 100 at a position above the mounting piece 111. This is a device that suppresses the vibration of the lower part of the bolt member 9 and stops the air conditioner 100 from swaying. This steady rest device 1 is constituted by, for example, two connecting members 2 and 3 having mutually symmetrical shapes. Among these two connecting members 2 and 3, one is the first connecting member 2 and the other is the second connecting member 3.

The connecting member 2 is arranged along the upper surface 110e of the air conditioner 100 at the upper end of one side surface 110a of the air conditioner 100, and is attached to a pair of mounting pieces 111, 111 provided at the bottom of both ends of the side surface 110a. The two connected bolt members 9 are connected to each other at the upper surface position of the air conditioner 100, and the relative displacement of the two bolt members 9 is restricted.

The connecting member 2 is a long member extending in the Y direction parallel to one side surface 110a, and includes a long flat plate portion 10 disposed so as to be joined to the upper surface 110e of the air conditioner 100, and a long flat plate portion 10 extending from the flat plate portion 10. It has a vertical plate part 14 that stands upright above. At both ends of the flat plate part 10, a pair of mounting pieces 111, 111 provided on the side surface 110a extends beyond the end of the upper surface 110e of the air conditioner 100 (the end in the -X direction). Wide bolt holding parts 11, 11 are provided.

On the other hand, the connecting member 3 has a structure symmetrical to that of the connecting member 2. That is, the connecting member 3 is an elongated member extending in the Y direction parallel to one side surface 110b, and is connected to an elongated flat plate portion 10 (not shown) disposed so as to be joined to the upper surface 110e of the air conditioner 100. , and a vertical plate part 14 that stands upright from the flat plate part 10. Also, at both ends of the flat plate portion 10 of the connecting member 3, a pair of mounting pieces 111, 111 provided on the side surface 110b beyond the end of the upper surface 110e (end in the +X direction) of the air conditioner 100 are located above. Wide bolt holding portions 11, 11 are provided that extend up to 100 mm.

The bolt holding parts 11, 11 of the connecting members 2, 3 are provided with a mounting part 15 for mounting the bolt member 9 at a position on the vertical line of the insertion part provided in the mounting pieces 111, 111. FIG. 1 illustrates a case where the mounting portion 15 is configured as a hole through which the bolt member 9 can be inserted. However, the attachment part 15 is not limited to this, and the attachment part 15 may be formed as a U-shaped notch that is open to the side ends of the bolt holding parts 11, 11. For example, by forming the mounting portion 15 as a U-shaped notch, even if the air conditioner 100 is already supported by the bolt member 9, the bolt holding portions 11, 11 of the connecting members 2, 3 can be attached. There is an advantage that it can be attached to the bolt member 9 by retrofitting.

Furthermore, first engaging portions 12, 12 are provided at both ends of the connecting members 2, 3 to engage with the upper ends of a pair of side surfaces 110c, 110d that are connected to both ends of each side surface 110a, 110b. For example, the first engaging portions 12, 12 are formed by bending both ends of the flat plate portion 10 downward by 90 degrees. By engaging these first engaging portions 12, 12 with the upper ends of the side surfaces 110c, 110d of the air conditioner 100, the connecting members 2, 3 are not displaced relative to the air conditioner 100 in the Y direction. Can be installed in any state.

Further, a second engaging portion 13 is provided at the center of the flat plate portion 10 of the connecting members 2, 3 to engage with the upper end portion of each side surface 110a, 110b. For example, the second engaging portion 13 is formed by bending a bent piece extending from the end of the central portion of the flat plate portion 10 downward by 90 degrees. The second engaging portion 13 is for restricting the connecting members 2 and 3 from being displaced relative to the air conditioner 100 in the X direction.

The connecting members 2 and 3 are provided at positions where the first engaging portions 12 and 12 and the second engaging portion 13 match the shape and size of the air conditioner 100. Therefore, the first engaging parts 12, 12 are arranged in a state in which they are engaged with the upper ends of the two side surfaces 110c, 110d, and the second engaging part 13 is engaged with the upper end parts of each side surface 110a, 110b. As a result, the connecting members 2 and 3 are positioned relative to the upper surface 110e of the air conditioner 100.

Furthermore, mounting portions 16, 16 for mounting connection bolts 31, 32 (see FIG. 2) are provided near both ends of the vertical plate portions 14 of the connection members 2, 3. The mounting parts 16, 16 are formed as holes into which the connecting bolts 31, 32 can be inserted, for example. However, the mounting parts 16, 16 are not necessarily limited to holes. For example, the mounting portion 16 may be formed as a U-shaped notch that is open to the upper end of the vertical plate portion 14.

In the steady rest device 1, the bolt member 9 is attached to the mounting portion 15 of the bolt holding portion 11 with the flat plate portion 10 of each connecting member 2, 3 arranged along the upper surface 110e of the air conditioner 100 as described above. The two nuts 21 and 22 that have been installed in advance on the top and bottom of the bolt member 9 with the bolt holding part 11 in between are tightened, so that the bolt holding part 11 is positioned above the mounting piece 111 and the bolt is inserted. It is fixed in a state where the member 9 is held. At this time, the connecting member 2 connects the two bolt members 9 connected to the pair of mounting pieces 111, 111 provided on the side surface 110a of the air conditioner 100 to each other at the upper surface position of the air conditioner 100. However, the two bolt members 9 are attached in such a manner that relative displacement thereof is restricted. The same applies to the connecting member 3, and the two bolt members 9 connected to the pair of mounting pieces 111, 111 provided on the side surface 110b of the air conditioner 100 are connected to each other at the upper surface position of the air conditioner 100. The two bolt members 9 are connected to each other and are attached in such a manner that relative displacement of the two bolt members 9 is restricted.

FIG. 2 is a diagram showing a state in which the steady rest device 1 is attached to the air conditioner 100. When the connecting members 2 and 3 are arranged on the upper surface 110e of the air conditioner 100 as described above, the connecting bolts 31 and 32 are inserted into the mounting portions 16 provided on the vertical plate portions 14 of the connecting members 2 and 3. It will be installed. That is, the connecting bolts 31 and 32 are inserted into the mounting portion 16, and the nuts 33 are tightened at both ends of the connecting bolts 31 and 32, so that the connecting members 2 and 3 are connected to each other by the two connecting bolts 31 and 32. It becomes connected. Thereby, the two connecting members 2 and 3 are fixed on the upper surface 110e of the air conditioner 100 so as not to be relatively displaced in the X direction.

In this way, the steady rest device 1 is attached so that the two connecting members 2 and 3 are not displaced relative to each other in both the X direction and the Y direction on the upper surface 110e of the air conditioner 100. In other words, each of the connecting members 2 and 3 connects the two bolt members 9 inserted through the mounting portions 15 of the bolt holding portion 11 projecting laterally at both ends of the flat plate portion 10 to the upper position of the mounting piece 111 (in the air). By connecting and fixing them at the same height position as the top surface 110e of the harmonizer 100, the two bolt members 9 are held so as not to be relatively displaced in the Y direction. Furthermore, since the connecting members 2 and 3 are connected to each other by connecting bolts 31 and 32, there is no relative displacement. As a result, the four bolt members 9 supporting the air conditioner 100 are fixed at the height position of the top surface 110e of the air conditioner 100 so as not to be relatively displaced in each of the X direction and the Y direction by the steady rest device 1. will be done. Therefore, the steady rest device 1 is designed to prevent the four bolt members 9 supporting the air conditioner 100 from vibrating between the mounting pieces 111, 111 and the bolt holding parts 11, 11. It is possible to hold it, and it exhibits a better steady rest effect than conventional ones.

The air conditioner 100 to which the steady rest device 1 is attached as described above is supported in a suspended state from a ceiling structure such as a ceiling slab. FIG. 3 is a diagram showing an example of a state in which the air conditioner 100 is installed in a ceiling space using the steady rest device 1. The example shown in FIG. 3 shows a state in which the air conditioner 100 is installed at a position relatively close to a ceiling structure 8 such as a ceiling slab. In this state, the distance H between the lower surface of the ceiling structure 8 and the upper surface of the air conditioner 100 is relatively small. Therefore, it is not possible to arrange a brace serving as a diagonal reinforcing member for the bolt member 9 hanging from the ceiling structure 8. However, by installing the steady rest device 1 of this embodiment on the top surface 110e of the air conditioner 100 and fixing the four bolt members 9 to the air conditioner 100 at the top surface position of the air conditioner 100, each bolt member 9 is fixed to the air conditioner 100 at an intermediate position between the upper end and the lower end. Therefore, even if an earthquake occurs, the steady rest device 1 can be held so that the lower portions of the four bolt members 9 do not undergo relative displacement, and the vibration width of the air conditioner 100 can be suppressed to a small level. Therefore, the steady rest device 1 of this embodiment exhibits the effect of preventing the air conditioner 100 from steadying even when a brace cannot be arranged.

FIG. 4 is a diagram showing another example of the air conditioner 100 installed in a ceiling space using the steady rest device 1. The example shown in FIG. 4 shows a state in which the air conditioner 100 is installed at a relatively distant position from the ceiling structure 8 such as a ceiling slab. In this state, the distance H between the lower surface of the ceiling structure 8 and the upper surface of the air conditioner 100 is relatively large, and the brace 61 serving as a diagonal reinforcing member is disposed on the upper part of the bolt member 9 hanging from the ceiling structure 8. Can be done. Therefore, the brace connecting fittings 60 are attached to the upper and lower parts of the bolt members 9, and the two braces 61 are arranged in a crossed manner between the two adjacent bolt members 9, and the upper and lower parts of each brace 61 are and are connected to the brace connection fitting 60. By arranging such braces 61 on four sides with the four bolt members 9 as vertices, the four bolt members 9 are in a state of being interconnected at their upper portions.

Further, the lower portions of the four bolt members 9 are fixed to the air conditioner 100 by the steady rest device 1. Therefore, even if an earthquake occurs, the vibration amplitude of the air conditioner 100 can be suppressed to a small level because the steady rest device 1 holds the lower portions of the four bolt members 9 so as not to be relatively displaced. In other words, in the steady rest device 1 of this embodiment, the lower part of the bolt member 9 where the steady rest effect cannot be obtained by the brace 61 is fixed to the upper surface of the air conditioner 100, so that the lower part of the bolt member 9 does not vibrate. It is possible to suppress vibrations of the air conditioner 100 due to

(Second embodiment)
Next, a second embodiment of the present invention will be described. In the first embodiment, the bolt member 9 connected to the mounting pieces 111, 111 of the air conditioner 100 is a hanging bolt installed in a hanging state in the ceiling space. In this embodiment, a steady rest device 1 will be described in which a vibration isolating member is provided in the steady rest device 1, and a hanging bolt can support the air conditioner 100 via the vibration isolating member.

FIG. 5 is a perspective view showing the support structure of the air conditioner 100 including the steady rest device 1 of the second embodiment. Moreover, FIG. 6 is a diagram showing a state in which the steady rest device 1 of the second embodiment is attached to the air conditioner 100. In this steady rest device 1, a vibration isolating member 40 is attached to the bolt holding parts 11, 11 of the connecting members 2, 3 described in the first embodiment. The vibration isolating member 40 is fixedly attached to the bolt holding parts 11, 11 of the connecting members 2, 3. The method of fixing the vibration isolating member 40 to the bolt holding parts 11, 11 is not particularly limited, and may be fixed by welding or may be fixed using bolts or nuts.

The vibration isolating member 40 has a rectangular frame body 41 made of metal. The vibration isolating member 40 has a hole 43 in the upper plate portion of its rectangular frame 41 through which a bolt member 9 such as a hanging bolt can be inserted, and a vibration isolating damper 42 made of a spring or the like is provided on the lower surface side of the hole 43. is installed. Further, a hole 44 through which a bolt member 50 can be inserted is provided in the lower plate portion of the rectangular frame 41 at a position coaxial with the hole 43 in the upper plate portion. The axis of this hole 44 coincides with the hole of the attachment part 15 provided in the bolt holding parts 11, 11 of the connecting members 2, 3. Therefore, the upper end portion of the bolt member 50 can be inserted into the hole 44 from the lower surface side of the connecting members 2 and 3.

In this steady rest device 1, the lower end of a bolt member 9 such as a hanging bolt installed in a ceiling space in a hanging state is inserted into a vibration isolating damper 42 through a hole 43 of a vibration isolating member 40, and a nut is inserted into the lower end of the bolt member 9. 45, it becomes supported by the bolt member 9. For example, the air conditioner 100, which is suspended from the ceiling, generates mechanical vibrations during operation. The vibration isolating member 40 is provided to prevent such mechanical vibration from propagating to the bolt member 9 and the ceiling structure.

On the other hand, the lower end portion of the bolt member 50 is attached to attachment pieces 111, 111 provided on the side surfaces 110a, 110b of the air conditioner 100 with two nuts 151, 152. The upper end of the bolt member 50 is inserted into the hole 44 of the connecting members 2, 3, and is fixed to the connecting members 2, 3 by tightening the nut 52. That is, the bolt member 50 is configured to support the air conditioner 100 while being physically separated from the bolt member 9 such as a hanging bolt.

Note that the other configuration of the steady rest device 1 is the same as that described in the first embodiment.

Therefore, in the steady rest device 1 of this embodiment, as in the first embodiment, each connecting member 2, 3 connects the two bolt members 50 connected to the mounting pieces 111, 111 of each side surface 110a, 110b with air. It can be fixed to the air conditioner 100 at the upper surface 110e of the conditioner 100 to suppress relative displacement in the Y direction. Further, in the steady rest device 1, as in the first embodiment, the respective connecting members 2 and 3 are connected by connecting bolts 31 and 32, so that the four bolt members 50 supporting the air conditioner 100 are Relative displacement within a plane can be suppressed. Therefore, the steady rest device 1 of this embodiment exhibits a better steady rest effect than the conventional one.

Furthermore, since the steady rest device 1 of this embodiment is connected via the vibration isolating member 40 to the lower end of the bolt member 9, such as a hanging bolt, hanging in the ceiling space, vibrations may occur during operation of the air conditioner 100. This structure prevents mechanical vibrations from propagating to ceiling structures such as ceiling slabs. This has the advantage of suppressing mechanical vibrations from being transmitted to the floor above the ceiling structure and creating a quiet floor space.

FIG. 7 is a diagram showing an example of a state in which the air conditioner 100 is installed in a ceiling space using the steady rest device 1 of this embodiment. The example shown in FIG. 7 shows a state in which the air conditioner 100 is installed at a position relatively close to a ceiling structure 8 such as a ceiling slab. In this state, the distance H between the lower surface of the ceiling structure 8 and the upper surface of the air conditioner 100 is relatively small. Therefore, it is not possible to arrange a brace serving as a diagonal reinforcing member for the bolt member 9 hanging from the ceiling structure 8. However, by installing the steady rest device 1 of this embodiment on the top surface 110e of the air conditioner 100 and fixing the four bolt members 50 to the air conditioner 100 at the top surface position of the air conditioner 100, each bolt member 50 is fixed to the air conditioner 100 at its upper end and lower end. Therefore, even if an earthquake occurs, the steady rest device 1 can hold the four bolt members 50 so that they do not undergo relative displacement, and the vibration width of the air conditioner 100 can be suppressed to a small level. Therefore, the steady rest device 1 of this embodiment exhibits the effect of preventing the air conditioner 100 from steadying even when a brace cannot be arranged.

FIG. 8 is a diagram showing another example of a state in which the air conditioner 100 is installed in a ceiling space using the steady rest device 1 of this embodiment. The example shown in FIG. 8 shows a state in which the air conditioner 100 is installed at a relatively distant position from a ceiling structure 8 such as a ceiling slab. In this state, the distance H between the lower surface of the ceiling structure 8 and the upper surface of the air conditioner 100 is relatively large, and the brace 61 serving as a diagonal reinforcing member is disposed on the upper part of the bolt member 9 hanging from the ceiling structure 8. Can be done. Therefore, the brace connecting fittings 60 are attached to the upper and lower parts of the bolt members 9, and the two braces 61 are arranged in a crossed manner between the two adjacent bolt members 9, and the upper and lower parts of each brace 61 are and are connected to the brace connection fitting 60. By arranging such braces 61 on four sides with the four bolt members 9 as vertices, the four bolt members 9 are in a state of being interconnected.

Furthermore, the four bolt members 50 that support the air conditioner 100 are fixed to the air conditioner 100 by the steady rest device 1. Therefore, even if an earthquake occurs, the vibration amplitude of the air conditioner 100 can be suppressed to a small level because the steady rest device 1 holds the four bolt members 50 so as not to be relatively displaced. In other words, in the steady rest device 1 of this embodiment, since the bolt member 50, which does not provide the steady rest effect by the brace 61, is fixed to the air conditioner 100, the vibration of the bolt member 950 causes the vibration of the air conditioner 100. Vibration can be suppressed.

(Third embodiment)
Next, a third embodiment of the present invention will be described. In the first and second embodiments described above, the hidden air conditioner 100 is exemplified as the object to be hung. On the other hand, in this embodiment, a case will be exemplified in which the object to be hung is an air conditioner 100 installed at the same height as the ceiling panel surface, such as a packaged air conditioner.

FIG. 9 is a perspective view showing a support structure of an air conditioner 100 including the steady rest device 1 of the third embodiment. Moreover, FIG. 10 is a diagram showing a state in which the steady rest device 1 of the third embodiment is attached to the air conditioner 100.

(Modified example)
Although several embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above. That is, the present invention includes various modifications of the embodiments described above.

For example, in the embodiment described above, the case where the steady rest device 1 is mainly attached to the air conditioner 100 is exemplified. However, the steady rest device 1 of the present invention can also be applied to ceiling hanging objects other than the air conditioner 100.

Moreover, in the embodiment described above, the case where the two connecting members 2 and 3 have mutually symmetrical shapes is illustrated. However, ceiling hanging objects such as the air conditioner 100 may not necessarily have a symmetrical shape. Therefore, the first connecting member 2 has a shape corresponding to the upper end of one side of the ceiling hanging object, and the second connecting member 3 has a shape corresponding to the upper end of the other side of the ceiling hanging object. It's good as well. That is, the two connecting members 2 and 3 do not necessarily need to have symmetrical shapes. In other words, it is sufficient that the two connecting members 2 and 3 can be arranged at the upper end portions of mutually opposing sides of the ceiling hanging object, so that each of the connecting members 2 and 3 can be arranged along the upper surface of the ceiling hanging object. In this case, if there are irregularities on the upper surface of the ceiling hanging object, the connecting members 2 and 3 may be shaped to follow such irregularities.

Further, in the above embodiment, the case where the flat plate portion 10 is provided with the first engaging portion 12 and the second engaging portion 13 is illustrated. These first engaging portions 12 and second engaging portions 13 are for positioning the steady rest device 1 so as not to be displaced relative to the air conditioner 100. However, when the flat plate part 10 is fixed to the upper surface of the air conditioner 100 using a fastening member such as a screw, it is not essential to provide the first engaging part 12 and the second engaging part 13.

Further, in the embodiment described above, the case where the two connecting members 2 and 3 are configured as separate bodies and connected using the connecting bolts 31 and 32 has been exemplified. However, the invention is not limited to this, and the steady rest device 1 may be realized as a structure in which the two connecting members 2 and 3 described above are integrated in advance.

Further, in the above embodiment, a ceiling slab is exemplified as an example of a ceiling structure in which a ceiling hanging object is installed. However, the ceiling structure in which ceiling hanging objects are installed is not necessarily limited to a ceiling slab. For example, if there is a structure constructed by assembling steel materials or the like in a ceiling space, a ceiling hanging object may be installed on such a structure.
