(Constitution)
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 X-Y-Z directions shown in these figures are orthogonal to each other. Specifically, the Z direction is perpendicular to the X direction and the Y direction is perpendicular to the vertical direction. In the following description, 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 the description is made using figures other than 2).

  As shown in FIGS. 1 and 2, the reinforcing mechanism 1 is an aseismatic reinforcing mechanism for aseismatic reinforcing the facility equipment 9 which is an air conditioning facility supported by the suspension bolts 91 suspended from the ceiling slab 92 which is the upper structure. Specifically, the reinforcing means is a reinforcing means for suppressing the swinging of the equipment 9 with respect to the ceiling slab 92, and includes, for example, the rod member 11, the vibration-damping member 12 of FIG. Note that “droop” indicates that the drooping is provided along the vertical direction (Z direction), and is, for example, a concept including hanging from a ceiling slab 92 and the like.

  Here, the installation device 9 is attached to and supported by the ceiling slab 92 which is the upper structure by the suspension bolt 91, and is, for example, an air conditioner as described above.

  The suspension bolt 91 is the support means described above, and more specifically, is suspended from the ceiling slab 92. Although the specific configuration and type of the suspension bolt 91 are arbitrary, for example, the upper end (+ Z direction) end is attached to the ceiling slab 92 and the lower end (−Z direction) is equipment It is attached to the four corners of 9, and as an example, it is a long thing provided four.

  Moreover, although the attachment method of the suspension bolt 91 with respect to the ceiling slab 92 and the installation apparatus 9 is also arbitrary, for example, the upper end (+ Z direction) edge part in the suspension bolt 91 is a fixture not shown embedded in the ceiling slab 92. The ceiling slab 92 and the suspension bolt 91 are freely rotatable at the joint point with respect to the insert, which is attached via a pin joint (not shown). Further, for example, the lower (+ Z direction) end of the suspension bolt 91 is fixed to the fixing member 93 fixed to the side surface at the four corners of the facility device 9 by any fixing means (for example, a screw or the like not shown). On the other hand, it is fixed and attached by any fixing means (for example, nut 94). By configuring in this manner, for example, a part (lower part in the present embodiment) on the equipment device 9 side of the suspension bolt 91 faces at least a part of the target equipment 9 in the horizontal direction.

(Configuration-bar member)
The rod member 11 in FIG. 2 is a member extending from the ceiling slab 92 to the equipment 9. Specifically, the upper end (+ Z direction) end side (one end side) of the rod member 11 is attached to the ceiling slab 92 The lower end (the -Z direction) end side (the other end side) of the self is a member provided to the facility device 9. Although the specific configuration and type of the rod member 11 are arbitrary, for example, the rod member 11 is suspended from the ceiling slab 92 to the upper surface of the facility device 9, and with the ceiling slab 92 in the vertical direction (Z direction). It is provided between the equipment 9 and at a position corresponding to the center of the equipment 9 in the horizontal direction (direction along the XY plane), and A single metal single pipe 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 the main body 111, the upper joint 112, and the lower joint A unit 113 is provided.

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

(Structure-bar-upper joint)
The upper joint portion 112 is a portion coupled to the main body portion 111 at the upper side (+ Z direction), and is a portion attached to the lower surface of the ceiling slab 92 via the vibration isolation member 12. It is a flat flange. Although the attachment method to the ceiling slab 92 of this upper side junction part 112 is arbitrary, it is attached using the anchor 112a which penetrates the upper side junction part 112 and the anti-vibration member 12, and reaches the ceiling slab 92, for example.

(Structure-Bar-Lower Joint)
The lower bonding portion 113 is a portion coupled to the main body portion 111 at the lower side (−Z direction), and is a portion disposed on the upper surface of the facility device 9 via the viscous body 13, for example , Rectangular flat flange.

(Configuration-anti-vibration member)
The anti-vibration 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, and more specifically, provided between the rod member 11 and the ceiling slab 92 For example, in addition to the function as the above-mentioned vibration transmission preventing means, it has a function of adjusting the unevenness on the lower surface of the ceiling slab 92. Note that "the natural vibration of the equipment 9" is a vibration unique to the equipment 9, specifically, mechanical vibration that occurs while the equipment 9 is always in operation, and the equipment 9 itself is For example, it is vibration that may occur regardless of whether or not an earthquake has occurred. Although the specific configuration and type of the vibration-proof member 12 are arbitrary, for example, it is sandwiched between the upper joint portion 112 and the ceiling slab 92, and as an example, it has elasticity such as rubber. It is an elastic body.

(Composition-viscous body)
The viscous body 13 is a sway reduction means for suppressing sway of the equipment 9 with respect to the ceiling slab 92, and specifically, is provided between the rod member 11 and the equipment 9. Here, “swing of the installation device 9 with respect to the ceiling slab 92” refers to relative swing of the installation device 9 with respect to the ceiling slab 92, specifically, swing in the horizontal direction, for example, as described above. The natural vibration is a vibration different from that of the natural vibration, which may occur at least when an earthquake occurs. Although the specific configuration and type of the viscous body 13 are arbitrary, for example, the viscous body 13 is sandwiched between the lower bonding portion 113 and the equipment 9, and as an example, a known material having viscosity And at least a property different from that of the above-described vibration isolation member 12.

(Mounting method)
Next, the attachment method of the reinforcement mechanism 1 comprised in this way is demonstrated. In particular, a method of attaching the reinforcing mechanism 1 to the facility device 9 attached to the ceiling slab 92 using the suspension bolt 91 will be described (the same applies to each embodiment other than the first embodiment).

  Although the attachment method is arbitrary, first, the bolt portion of the anchor 112 a is positioned with respect to the ceiling slab 92. Here, positioning is performed at a position facing the vicinity of the center in the horizontal direction of the upper surface of the facility device 9 and 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 in the ceiling slab 92 is performed. Next, as shown in FIG. 2, after the rod member 11 is provided via the vibration isolation member 12, the nut portion of the anchor 112a is screwed into the bolt portion of the anchor 112a (that is, for example, fitting by screwing) By fixing them, the rod member 11 is fixed to the ceiling slab 92 via the vibration isolation member 12.

  Next, after the viscous body 13 is disposed on the upper surface of the facility device 9, the facility device 9 is attached to the suspension bolt 91. In this case, the viscous body 13 is disposed between the rod member 11 and the equipment 9. This completes the attachment of the reinforcement mechanism 1.

(Transmission of force by earthquake shaking)
Next, transmission of force due to earthquake shaking in the attached reinforcing mechanism 1 will be described. For example, when an earthquake occurs, the equipment 9 shakes horizontally with respect to the ceiling slab 92. In this case, the inertia force of the equipment 9 due to this shaking, mainly the ceiling slab via the reinforcement mechanism 1 Since the power is transmitted to 92, the force transmitted to the ceiling slab 92 via the suspension bolt 91 is weakened, and a reduction in the strength of the suspension bolt 91 can be prevented. In particular, it may be assumed that unevenness is present on the lower surface of the ceiling slab 92 and the upper surface of the equipment 9, but even in this case, the rod member 11 has the ceiling slab 92 via the vibration isolation member 12 and the viscous member 13. Of the strength of the suspension bolt 91 because the inertia force of the equipment 9 due to the shaking of the earthquake can be transmitted to the ceiling slab 92 through the reinforcing mechanism 1 because it is attached to the lower surface of the equipment and the upper surface of the equipment 9. A drop can be reliably prevented. Moreover, 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 junction point, and an earthquake occurs. Since the bending stress applied to the suspension bolt 91 can be reduced when the equipment 9 shakes, it is possible to prevent the reduction in the strength of the suspension bolt 91 more reliably.

(Effect of this embodiment)
According to the present embodiment, by preventing the swing of the facility device 9 with respect to the ceiling slab 92, for example, the force transmitted from the facility device 9 side to the suspension bolt 91 by the swing of the facility device 9 (in one example, inertia) Since the force) can be reduced, a reduction in the strength of the suspension bolt 91 can be prevented.

  Further, by providing the viscous body 13, for example, the vibration of the equipment 9 or the force (in one example, the inertial force) transmitted from the side of the equipment 9 to the side of the suspension bolt 91 can be further reduced. The acceleration generated in the facility device 9 due to the shaking of the device 9 can be reduced, and a reduction in the strength of the suspension bolt 91 can be reliably prevented.

  Further, by providing the vibration isolation member 12, for example, it is possible to prevent transmission of the natural vibration of the equipment 9 to the ceiling slab 92, so the ceiling slab 92 vibrates due to the natural vibration of the equipment 9. Can be prevented.

  Moreover, since the rod member 11 is suspended from the ceiling slab 92 to the upper surface of the facility device 9, for example, the rod member 11 can be sandwiched and supported between the ceiling slab 92 and the facility device 9, It is possible to prevent the rod member 11 from coming off and to prevent the reduction in the strength of the suspension bolt 91 with certainty. Further, since the ceiling slab 92 and the equipment 9 can be connected to each other by the rod member 11 in the shortest distance, the length of the rod member 11 is shortened, and the weight reduction and cost reduction of the reinforcement mechanism 1 are achieved. It is possible to achieve high construction efficiency while planning.

The upper load transfer portion 321 is a transfer means for transferring the horizontal load transmitted from the facility device 9 to the interference member 31 from the interference member 31 to the suspension bolt 91 when the facility device 9 swings in the horizontal direction. Specifically, it is a member provided between the interference member 31 and the upper bonding portion 323, for example, a member attached to the interference member 31 and the side bonding portion 323, and also shown in FIG. Thus, it is a triangular metal plate which spreads from the upper bonding portion 323 side toward the interference member 31 side. Although the attachment method to the interference member 31 of this upper side load transfer part 321 is arbitrary, it is attached by pin joint so that it may turn, for example based on the upper side 1st connection pin 321a of FIG. Further, although the method of attaching the upper load transfer portion 321 to the upper joint portion 323 is arbitrary, for example, it is attached by pin joint so as to be rotatable on the basis of the upper second connection pin 321b.

Although the attachment method to the suspension bolt 91 of this upper side joint part 323 is arbitrary, for example, the upper side joint part 323 itself adopts a so-called known split nut structure, and the upper joint part 323 is broken to make the suspension bolt 91 It is what is attached by fixing after arranging. With such a configuration, the upper joint 323 can be attached to the suspension bolt 91 without removing the suspension bolt 91 itself from the ceiling slab 92 or removing the equipment 9 from the suspension bolt 91.

Next, the attachment method of the damage prevention mechanism 3 comprised in this way is demonstrated.

  Specifically, first, the attachment positions of the upper joint 323 and the lower joint 324 in the suspension bolt 91 are determined. Here, since each element of the damage prevention mechanism 3 is rotatable on the basis of each connection pin, the upper joint 323 and the lower joint 324 are mutually separated in the vertical direction (Z direction). In the case where the interference member 31 separates from the equipment 9 in the horizontal direction, while the upper joint 323 and the lower joint 324 are brought close to each other in the vertical direction (Z direction), the interference member 31 is equipment in the horizontal direction Focusing on approaching to 9, mounting so that the interference member 31 faces the side surface of the facility device 9 in a non-contact manner via a slight gap (for example, a gap of about several mm to about several tens of mm) Determine the position.

The interference member 41 is an interference means provided between the equipment 9 in the horizontal direction and a part of the suspension bolt 91. Specifically, when the equipment 9 does not shake in the horizontal direction, the interference member 41 is equipment. It is a member which is apart from 9 and which contacts and interferes with the equipment 9 when the equipment 9 shakes in the horizontal direction. Although the specific configuration and type of the interference member 41 are arbitrary, for example, a slight gap (for example, a gap of about several mm to about several tens of mm) is provided to the side surface of the facility device 9 in a non-swinging state.
