However, if other equipment (eg, piping, ducts, etc.) is provided around the equipment, these other equipment may get in the way and it may be difficult to properly attach the brace. rice field. On the other hand, even if the brace is properly attached, the equipment will shake due to the shaking of the earthquake, and the part of the hanging bolt to which the brace is joined (for example, the part attached to the slab in the hanging bolt, hanging) There is a possibility that the strength of the part of the bolt where the brace is provided, or the part of the hanging bolt that comes into contact with the swaying equipment, etc.) is reduced. Therefore, there has been a demand for a technique for preventing a decrease in the strength of the support member.

(Embodiment)
First, the first embodiment will be described. In this embodiment, a case where the “seismic retrofitting mechanism” is a reinforcing mechanism and the “rod member” of the reinforcing mechanism hangs down from the superstructure to the equipment will be described.

(composition)
First, the configuration of the reinforcing mechanism according to the present embodiment will be described. FIG. 1 is a perspective view showing a reinforcing mechanism and the like according to the present embodiment, and FIG. 2 is a side view showing the reinforcing mechanism and the like. In the following description, the XYZ directions shown in each of these figures are orthogonal to each other. Specifically, the Z direction is the vertical direction, and the X and Y directions are relative to the vertical direction. For example, the Z direction is referred to as the height direction, the + Z direction is referred to as the upper side (plane), and the −Z direction is referred to as the lower side (bottom surface). The same applies to the case where each figure other than 2 is used for explanation).

As shown in FIGS. 1 and 2, the reinforcing mechanism 1 is a seismic reinforcing mechanism that seismically reinforces equipment 9 which is an air conditioner supported by a hanging bolt 91 suspended from a ceiling slab 92 which is an upper structure. Specifically, it is a reinforcing means for suppressing the shaking of the equipment 9 with respect to the ceiling slab 92, and includes, for example, a rod member 11, a vibration isolator member 12 of FIG. 2, and a viscous body 13. The term "hanging" indicates that the slab is provided along the vertical direction (Z direction), and is a concept including, for example, being suspended from the ceiling slab 92.

Here, the equipment 9 is attached to and supported by a ceiling slab 92, which is a superstructure, by a hanging bolt 91, and is, for example, an air conditioner as described above.

The hanging bolt 91 is the above-mentioned support means, and specifically, is hung from the ceiling slab 92. The specific configuration and type of the hanging bolt 91 are arbitrary, but for example, the upper end (+ Z direction) is attached to the ceiling slab 92, and the lower (−Z direction) end is equipment. It is attached to the four corners of 9, and as an example, it is a long one provided with four.

Further, the method of attaching the hanging bolt 91 to the ceiling slab 92 and the equipment 9 is also arbitrary. For example, the upper end (+ Z direction) of the hanging bolt 91 is a fixture (not shown) embedded in the ceiling slab 92. The insert is attached to the insert by pin-joining it via a pin joint (not shown), and the ceiling slab 92 and the suspension bolt 91 are freely rotatable at the joint point. Further, for example, the lower end (+ Z direction) of the suspension bolt 91 is attached to the fixing member 93 fixed to the side surfaces at the four corners of the equipment 9 by arbitrary fixing means (for example, screws (not shown)). On the other hand, it is fixed and attached by an arbitrary fixing means (for example, a nut 94). With this configuration, for example, a part of the suspension bolt 91 on the equipment 9 side (lower part in the present embodiment) faces at least a part of the target equipment 9 in the horizontal direction.

(Structure-bar member)
The rod member 11 in FIG. 2 is a member extending from the ceiling slab 92 to the equipment 9, and specifically, the end side (one end side) on the upper side (+ Z direction) of the bar member 11 is attached to the ceiling slab 92. At the same time, the lower side (-Z direction) of the self (the other end side) is a member provided in the equipment 9. The specific configuration and type of the rod member 11 are arbitrary, but for example, the rod member 11 is hung from the ceiling slab 92 on the upper surface of the equipment 9, and is referred to as the ceiling slab 92 in the vertical direction (Z direction). It is provided between the equipment 9 and the equipment 9 at a position corresponding to the center of the equipment 9 in the horizontal direction (direction along the XY plane), and is provided in the vertical direction (direction along the XY plane). Only one metal single tube that is slightly shorter than the distance from the lower surface of the ceiling slab 92 to the upper surface of the installation device 9 in the Z direction), and also has the main body 111, the upper joint 112, and the lower joint. The unit 113 is provided.

(Structure-Bar member-Main body)
The main body 111 is a cylindrical portion extending along the vertical direction (Z direction) between the ceiling slab 92 and the equipment 9.

(Structure-Bar member-Upper joint)
The upper joint portion 112 is a portion that is connected to the main body portion 111 on the upper side (+ Z direction), and is a portion that is attached to the lower surface of the ceiling slab 92 via the vibration isolator member 12, for example, a rectangular shape. It is a flat plate-shaped flange. The method of attaching the upper joint portion 112 to the ceiling slab 92 is arbitrary, but for example, a plurality of anchors 112a that penetrate the upper joint portion 112 and the vibration isolator member 12 and reach the ceiling slab 92 are used for attachment.

(Structure-Bar member-Lower joint)
The lower joint portion 113 is a portion that is coupled to the main body portion 111 on the lower side (−Z direction), and is a portion that is arranged on the upper surface of the equipment 9 via the viscous body 13, for example. , A rectangular flat flange.

(Structure-vibration isolation member)
The vibration isolator member 12 is a vibration transmission preventing means for preventing the natural vibration of the equipment 9 from being transmitted to the ceiling slab 92. Specifically, the vibration isolator member 12 is provided between the rod member 11 and the ceiling slab 92. For example, it has a function of adjusting the unevenness on the lower surface of the ceiling slab 92 as well as a function of the above-mentioned vibration transmission preventing means. The "natural vibration of the equipment 9" is a vibration peculiar to the equipment 9, specifically, a mechanical vibration generated while the equipment 9 is always in operation, and the equipment 9 itself. It is the vibration caused by the vibration source, and is, for example, the vibration that can occur regardless of whether or not an earthquake has occurred. The specific configuration and type of the anti-vibration member 12 are arbitrary, but for example, they are sandwiched between the upper joint portion 112 and the ceiling slab 92, and as an example, they have elasticity such as rubber. It is an elastic body.

(Construction-viscous body)
The viscous body 13 is a shaking reducing means for suppressing the shaking of the equipment 9 with respect to the ceiling slab 92, and specifically, the viscous body 13 is provided between the rod member 11 and the equipment 9. The "sway of the equipment 9 with respect to the ceiling slab 92" here is a relative sway of the equipment 9 with respect to the ceiling slab 92, specifically, a sway in the horizontal direction. It is a tremor different from the natural vibration, and is a tremor that can occur at least when an earthquake occurs. The specific configuration and type of the viscous body 13 are arbitrary, but for example, the viscous body 13 is sandwiched between the lower joint portion 113 and the equipment 9, and as an example, a known material having viscosity. At least, it has properties different from those of the above-mentioned anti-vibration member 12.

(Mounting method)
Next, a mounting method of the reinforcing mechanism 1 configured in this way will be described. In particular, a method of attaching the reinforcing mechanism 1 to the equipment 9 attached to the ceiling slab 92 by using the suspension bolt 91 will be described (the same applies to each embodiment other than the first embodiment).

The mounting method is arbitrary, but first, the bolt portion of the anchor 112a is positioned with respect to the ceiling slab 92. Here, positioning is performed at a position opposite to the vicinity of the center in the horizontal direction of the upper surface of the equipment 9 in the vertical direction (Z direction). Next, after removing the equipment 9 from the suspension bolt 91, the bolt portion of the anchor 112a is provided at the position where the positioning is performed on the ceiling slab 92 described above. Next, as shown in FIG. 2, after providing the rod member 11 via the vibration isolator member 12, the nut portion of the anchor 112a is screwed into the bolt portion of the anchor 112a (that is, for example, it is fitted by a screwing action). By matching), the rod member 11 is fixed to the ceiling slab 92 via the vibration isolator member 12.

Next, after arranging the viscous body 13 on the upper surface of the equipment 9, the equipment 9 is attached to the hanging bolt 91. In this case, the viscous body 13 is arranged between the rod member 11 and the equipment 9. This completes the installation of the reinforcing mechanism 1.

(Transmission of force due to the shaking of an earthquake)
Next, the transmission of the force due to the shaking of the earthquake in the attached reinforcing mechanism 1 will be described. For example, when an earthquake occurs, the equipment 9 sways in the horizontal direction with respect to the ceiling slab 92. In this case, the inertial force of the equipment 9 due to this sway, mainly through the reinforcing mechanism 1, the ceiling slab. Since it is transmitted to the suspension bolt 91, the force transmitted to the ceiling slab 92 via the suspension bolt 91 is weakened, and it is possible to prevent a decrease in the strength of the suspension bolt 91. In particular, it can be assumed that the lower surface of the ceiling slab 92 and the upper surface of the equipment 9 have irregularities, but even in this case, the rod member 11 passes through the vibration isolator member 12 and the viscous body 13 to the ceiling slab 92. Since it is attached to the lower surface of the equipment 9 and the upper surface of the equipment 9, the inertial force of the equipment 9 due to the shaking of the earthquake can be transmitted to the ceiling slab 92 via the reinforcing mechanism 1, so that the strength of the suspension bolt 91 can be increased. The decrease can be surely prevented. Further, in particular, since the suspension bolt 91 is attached to the ceiling slab 92 via a pin joint (not shown), the ceiling slab 92 and the suspension bolt 91 are free to rotate at the joint point, and an earthquake occurs. Since the bending stress applied to the suspension bolt 91 when the equipment 9 is shaken can be reduced, it is possible to more reliably prevent a decrease in the strength of the suspension bolt 91.

(Effect of this embodiment)
According to the present embodiment, by preventing the equipment 9 from shaking with respect to the ceiling slab 92, for example, a force transmitted from the equipment 9 side to the suspension bolt 91 due to the shaking of the equipment 9 (for example, inertia). Since the force) can be reduced, it is possible to prevent a decrease in the strength of the hanging bolt 91.

Further, by providing the viscous body 13, for example, the shaking of the equipment 9 and the force transmitted from the equipment 9 side to the suspension bolt 91 side (for example, the inertial force) can be further reduced, so that the equipment can be further reduced. The acceleration generated in the equipment 9 due to the shaking of the equipment 9 can be reduced, and the decrease in the strength of the suspension bolt 91 can be reliably prevented.

Further, by providing the anti-vibration member 12, for example, it is possible to prevent the natural vibration of the equipment 9 from being transmitted to the ceiling slab 92, so that the ceiling slab 92 vibrates due to the natural vibration of the equipment 9. Can be prevented.

Further, since the rod member 11 is hung from the ceiling slab 92 on the upper surface of the equipment 9, for example, the rod member 11 can be sandwiched and supported between the ceiling slab 92 and the equipment 9. It is possible to prevent the rod member 11 from coming off and surely prevent a decrease in the strength of the hanging bolt 91. Further, since the ceiling slab 92 and the equipment 9 can be connected to each other by the rod member 11 at the shortest distance, the length of the rod member 11 can be shortened to reduce the weight and cost of the reinforcing mechanism 1. Along with this, high workability can be achieved.

(Embodiment 2)
Next, the second embodiment will be described. In this embodiment, a case where the “seismic retrofitting mechanism” is a reinforcing mechanism and the “rod member” of the reinforcing mechanism is inclined from the superstructure to the equipment will be described.
