Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a hanging frame used for hanging and installing an air conditioner or the like from the ceiling of a building.

For example, as shown in FIGS. 7 and 8, a suspension frame 102 for suspending an air conditioner 101 or the like from a ceiling 100 of a building is known.

Here, reference numeral 103 denotes a vibration isolator provided as a countermeasure against vibrations such as earthquakes, which is arranged between the suspension frame 102 and the air conditioner 101, and its upper end 103a is connected to the lower surface 102a of the suspension frame 102. The lower end 103b of the air conditioner 101 is connected to the hanging metal fitting 101b of the air conditioner 101 on the upper surface 101a of the air conditioner 101 .

By the way, in order to suppress the horizontal vibration of the air conditioner 101 that occurs when an earthquake occurs, the stopper member 104 extends downward from the lower surface 102a of the suspension frame 102, and the lower end 104a of the stopper member 104 extends laterally of the air conditioner 101. It can suppress shaking.

However, in such a method, the separation distance between the air conditioner 101 and the suspension frame 102 becomes long, so the length of the stopper member 104 also becomes large. In other words, there was a problem that the anti-vibration countermeasure for seismic reinforcement measures was large-scale, and it was necessary to use expensive and strong materials.

SUMMARY OF THE INVENTION In consideration of the conventional problems described above, it is an object of the present invention to provide a suspension mount that is compact in anti-vibration measures for seismic reinforcement and is inexpensive in cost.

In a state in which the target device is suspended from the vibration isolator, the anti-vibration frame member is spaced apart from the vibration isolator, and the stopper member extends horizontally with respect to the target device. Suspension mounts are arranged at opposite positions with a predetermined interval.

In such a configuration, when the stopper member is attached directly to the frame on which the anti-vibration device is suspended as in the conventional method, the stopper member must be elongated in the vertical direction. Since the anti-vibration frame member is attached below the frame that suspends the anti-vibration device, and the stopper member is attached to the anti-vibration frame member, the horizontal stress on the stopper member is small when the target equipment collides, so it is inexpensive. material can be used. That is, it is possible to use a material that can withstand a small stress and to reduce the cost.

Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view showing an example of a hanging stand according to an embodiment of the present invention, FIG. 2 is a schematic side sectional view thereof, and FIGS. 3, 4, 5 and 6 are perspective views seen from various angles. It is a diagram.

A main body 12 of the suspension frame suspends a substantially rectangular parallelepiped air conditioner 101 from the ceiling 100 of the building. Here, reference numeral 103 is a vibration isolator provided for anti-vibration measures. , and the lower end 103b thereof is connected to the hanging metal fitting 101b of the air conditioner 101 on the upper surface 101a of the air conditioner 101. As shown in FIG.

Furthermore, reference numeral 1 denotes a frame member for anti-seismic reinforcement (hereinafter simply referred to as a frame member for anti-vibration), which is fixed to the lower portion 12a of the main body 12 of the hanging frame. Its shape is composed of a substantially rectangular lower frame 1b, four vertical frames 1a erected at each corner, and two vertical frames 1c erected in the middle. The four vertical frames 1a, 1a, 1a, 1a and the two vertical frames 1c are fixed to the lower part 12a of the main body 12 of the hanging frame.

On the other hand, the lower surface frame 1b has a frame shape along each side of the substantially rectangular upper surface 101a of the air conditioner 101 to be suspended. However, of the four side frames 1b1, 1b2, 1b3, and 1b4 that constitute the lower frame 1b, a pair of opposing frames are arranged inside each side of the upper surface 101a of the air conditioner 101. ing.

In the illustrated embodiment, side frames 1b1 and 1b3 are positioned inwards and side frames 1b2 and 1b4 are positioned slightly outwards. With such a configuration, there is an advantage that the inward side frames 1b1 and 1b3 come into contact with the upper surface of the air conditioner 101 and play a role of a stopper against pitching caused by an earthquake. Note that all four side frames may be arranged inside. In this way, the steady rest frame member 1 has the same degree of skeleton (especially in the horizontal direction) as the main body 12 of the suspension cradle.

In this embodiment, the anti-vibration device 103 is arranged outside the lower surface frame 1b of the anti-vibration frame member 1. As shown in FIG.

Further, a stopper member 2 is attached to a predetermined portion of the frame member 1 for anti-vibration. That is, as shown in FIGS. 3(A) and 3(B), in this embodiment, two stopper members 2 are attached to each of the side frame 1b1 and the side frame 1b3 at a predetermined interval. FIG. 3B is a partially enlarged schematic sectional enlarged view. The side frame 1b1 and the side frame 1b3 are L-shaped frames, and are attached so that the vertical portion 1b1b is located inside the horizontal portion 1b1a. The L-shaped stopper member 2 is arranged such that the horizontal portion 2b is located inside the vertical portion 2a, and the horizontal portion 2b and the horizontal portions 1b1a of the side frames 1b1 and 1b3 are overlapped with each other to form two pieces. The stopper member 2 is attached to the side frames 1b1 and 1b3 by being fixed to each other with bolts.

Further, the inner side of the vertical portion 2a of the stopper member 2 is arranged at a position opposed to each side of the upper surface 101a of the air conditioner 101 in the suspended state with a predetermined gap in the horizontal direction. This is to provide a margin within a range that does not impair the function of the anti-vibration device 103 . And when a large horizontal shake occurs, it exerts a stopper function by contacting it. As a result, the air conditioning equipment 101 can be prevented from falling off due to breakage of the equipment hanging bolts due to the horizontal rocking of the air conditioning equipment 101, and from stopping functioning due to damage to pipes or the like connected to the air conditioning equipment.

On the other hand, the side frames 1b2 and 1b4 are L-shaped frames like the side frames 1b1 and 1b3, but as shown in FIGS. It is installed so that it comes to the outside. FIG. 3(C) is a partially enlarged schematic sectional view. The L-shaped stopper member 3 is arranged so that the horizontal portion 3b is located outside the vertical portion 3a, and the horizontal portion 3b and the horizontal portions 1b2a of the side frames 1b2 and 1b4 are overlapped with each other. The stopper member 3 is attached to the side frames 1b2 and 1b4 by being mutually fixed with two bolts.

Further, the outer side of the vertical portion 3a of the stopper member 3 is arranged at a position opposed to each side of the upper surface 101a of the air conditioner 101 in the suspended state with a predetermined gap in the horizontal direction. This is to provide a margin within a range that does not impair the function of the anti-vibration device 103 as described above. And when a large horizontal shake occurs, it exerts a stopper function by contacting it.

It should be noted that the stopper members 2 and 3 are characterized in that the horizontal width of the stopper members 2 and 3 cannot be made very long because the shape of the upper surface of the air conditioner 101 or the like to be hung varies. In the case of this embodiment, instead of directly attaching the stopper members 2 and 3 to the main body 12 of the suspension frame, the anti-vibration frame member 1 having the same skeleton (especially in the horizontal direction) as the main body 12 of the suspension frame. Since it is attached to the lower part of the , there is an advantage that it can control the vibration without making it a vertically long member like the conventional one.

The lower part of the anti-vibration frame member of the present invention is not limited to a rectangular shape, and may be circular as long as it follows the outer periphery of the upper part of the target device.

Also, the number of stopper members of the present invention is not particularly limited, but it is desirable that at least one stopper member be arranged in at least four directions because the shaking of an earthquake may occur from either the left or the right, but the present invention is not limited to this.

The suspension frame according to the present invention is useful as a suspension frame for suspending air conditioners, etc., because the stopper member of the present invention is compact as a countermeasure against vibrations such as earthquakes, and the cost is low.
