DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A suspended metal article according to a first embodiment of the present invention will be described with reference to FIGS. This hanging hardware is fixed to the floor panel 10 on the second floor and suspends the ceiling base panel 11 on the first floor. The upper hardware 1, the lower hardware 2 and the two hardwares 1, 2
A vibration-proof rubber 3 for connecting the 2 and 3 are side views of FIG.

The upper metal 1 is flat and has a notch 4 at the top.
Is provided and a hole 5 is bored in the middle part. The notch 4 is shaped so that the lower flange 10a of the frame of the floor panel 10 can be press-fitted and fixed. The lower hardware 2 includes a locking portion 6 that is inserted into the hole portion 5 so as to be locked, a ceiling base panel 1
1 has a fixing portion 7. Specifically, the vertical piece 2a of a substantially L-shaped flat plate is bent, its tip is further bent downward, and both sides are cut off to form the locking portion 6. Further, a horizontal piece of a substantially L-shaped flat plate is bent at a right angle, and a fixing tool insertion hole 8 is provided on the adjacent surface thereof to form the fixing portion 7.

The anti-vibration rubber 3 connects the lower portion of the hole 5 of the upper metal 1 and the vertical portion of the vertical piece 2a of the lower metal 2 and ascends to the lower metal 2 as shown in FIG. Is formed into a columnar shape. In a state where the upper metal 1 and the lower metal 2 are connected by the anti-vibration rubber 3, the locking portion 6 is set to be spaced from the peripheral edge of the hole 5. At the time of construction, the fixing portion 7 is fixed to the ceiling base panel 11 by the fasteners 12, and the notch portion 4 is press-fitted into the lower flange 10a of the frame of the floor panel 10 and locked. As a result, the ceiling base panel 11 is hung on the floor panel 10 via the hanging hardware. In this case, as shown in FIG. 5 and FIG. 6, since the fixing portion 7 is L-shaped, it can be fixed to the field edge of the ceiling base panel 11 that intersects in a grid pattern on the front or side of the hanging object. The anti-vibration rubber 3 elastically deforms with the weight of the ceiling base panel 11, but the stability is good because the lower metal 2 side on which the load is applied is higher.

In this embodiment, an upper metal piece 1 attached to the floor panel 10 side and a lower metal piece 2 attached to the ceiling base panel 11 side are separated, and the upper metal piece 1 and the lower metal piece 2 are connected by a vibration-proof rubber 3. As a result, the impact sound of the floor panel 10 is absorbed by the anti-vibration rubber 3 and is unlikely to be transmitted to the ceiling base panel 11 below. Therefore, the vibration amplitude to the ceiling surface is reduced even if there is no ceiling sound insulation material (3 for each frequency).
The noise level of the floor panel 10 is reduced (about 2/3 of the conventional level). Further, when the vibration-proof rubber 3 is reduced in strength due to combustion or the like, the locking portion 6 of the lower metal piece 2 is locked in the hole 5 of the upper metal piece 1 and the ceiling base panel 11 is suspended and dropped. There is nothing to do.

The hanging hardware of the second embodiment will be described with reference to FIGS. 7 to 9. In this hanging hardware, the vibration-proof rubber 3'is hollow, and the rubber 12 as shown in FIG. 9 can be inserted into the hollow portion 16 thereof. For this reason, holes 13 and 14 are also provided in the lower portion of the hole 5 of the upper metal 1 and the vertical portion of the vertical piece 2a of the lower metal 2. The rubber 12 has a spring constant different from that of the anti-vibration rubber 3 ', and plates 15 and 15 for closing the holes 13 and 14 are attached to both ends thereof. The other structure is the same as that of the first embodiment, and the same portions are denoted by the same reference numerals and the description thereof is omitted.

In this embodiment, only the anti-vibration rubber 3'is used for the part that suspends only the ceiling, and the hollow part 16 of the anti-vibration rubber 3'is used for the part where heavy lighting equipment is attached to the ceiling. The rubber 12 is inserted into and the spring constant is increased. This makes it possible to reduce the initial displacement amount of the anti-vibration rubber 3 '. In this way, the spring constant of the anti-vibration rubber 3'can be increased, so that it is effective for a portion such as a heavy lighting fixture to which a large load is applied. Other effects are similar to those of the first embodiment.

The hanging hardware of the third embodiment will be described with reference to FIG. The hanging hardware includes an L-shaped upper hardware 20 including a horizontal piece 20a fixed to a lower flange 10a of a frame of the floor panel 10 and a vertical piece 20b rising from the horizontal piece 20a to the inside of the floor panel 10, and a ceiling base. The fixed part 21a fixed to the panel 11 and the floor panel 1 from the fixed part 21a
0 is provided with a lower metal piece 21 formed of an extension portion 21b extending into the interior of the floor panel 0, and a vibration-proof rubber 22 located inside the floor panel 10 and connecting the vertical piece 20b and the extension portion 21b. is there. The horizontal portion 20a of the upper hardware 20 is fixed to the lower flange 10a of the frame of the floor panel 10 with bolts, nuts and washers (not shown). Fixed part 21 of the lower hardware 21
Similarly to the first embodiment, a is L-shaped and has fastener insertion holes formed on the adjacent surfaces. The anti-vibration rubber 22 has the same shape as that of the first embodiment or the second embodiment.

In this embodiment, as in the first embodiment, the impact sound of the floor panel 10 is absorbed by the anti-vibration rubber 22,
The floor panel 10 is less likely to be propagated to the ceiling base panel 11 below, and the vibration amplitude to the ceiling surface is reduced without the ceiling sound insulation material.
It also reduces the impact noise. In addition, the upper hardware 20 and the lower hardware 2
Since 1 is connected to the inside of the floor panel 10 by the vibration-proof rubber, there is no problem even in the arrangement in which the space between the floor panel 10 and the ceiling base panel 11 is small.

[0017]

According to the hanging hardware of claim 1, it is separated into an upper metal fitting attached to the floor panel side and a lower metal fitting attached to the ceiling base panel side, and the upper metal fitting and the lower metal fitting are connected by a vibration-proof rubber. Therefore, the impact sound of the floor panel is absorbed by the anti-vibration rubber and is difficult to be transmitted to the ceiling base panel below. Therefore, the vibration amplitude to the ceiling surface is reduced and the impact sound of the floor panel is also reduced without the ceiling sound insulating material. Further, when the anti-vibration rubber is reduced in strength due to combustion or the like, the locking part of the lower metal piece is locked in the hole of the upper metal piece, and the ceiling base panel is not suspended and does not fall off.

According to the hanging hardware of claim 2, as in claim 1, the impact sound of the floor panel is absorbed by the anti-vibration rubber and is difficult to be propagated to the ceiling base panel below, and the ceiling does not have a sound insulating material. The vibration amplitude to the surface is reduced and the impact noise of the floor panel is also reduced. Further, since the upper metal member and the lower metal member are connected to each other by the rubber vibration proof inside the floor panel, there is no problem even in the arrangement in which the space between the floor panel and the ceiling base panel is small.
