Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a soundproof ceiling that prevents floor noise from being transmitted upstairs.

[Background technology]

Conventionally, as shown in FIG. 1, a ceiling frame 4 with a ceiling finishing material 5 stretched through a frame support member 2 is attached to a floor structure 1 that holds an upper floor. There was a problem in that the floor sound from the upper floor was transmitted to the ceiling at the lower floor via the floor structure 1, the frame support member 2, and the ceiling frame 4.

[Purpose of invention]

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a soundproof ceiling that can prevent the sound of the floor above from being transmitted to the downstairs.

[Disclosure of the invention] In the soundproof ceiling of the invention, a frame support member 2 is attached to a floor structure 1 that holds an upper floor.
and the ceiling frame body 4 with a substantially U-shaped hanging tool 9.
At the same time, a substantially U-shaped impact buffer 3 is interposed on the inner periphery to support the ceiling frame 4 by fixing both side pieces 9a of the hanging tool 9 to the other side, and supporting the ceiling frame 4 on the frame support member 2.
It is made up of a ceiling frame body 4 with a ceiling finishing material 5 stretched over it, and this structure achieves the above object.

The present invention will be described below based on embodiments shown in the accompanying drawings. Figure 2 shows an embodiment of the present invention.
A hanging tree 2a as a frame support member 2 is fixed by driving six nails at the upper end to a floor structure 1, such as a metal beam made of large wire or channel steel, which is attached and fixed to the four corners that hold the floor. In this embodiment, the ceiling frame body 4 consists of a field edge receiver 7 and a ceiling edge 8.
A substantially U-shaped metal hanging tool 9 is attached from below with a U-shaped shock absorbing material 3 interposed therebetween to hold the field edge receiver 7, and both sides 9a of the hanging tool 9 are attached to the hanging rod. A ceiling frame body 4 is supported by fixing with 10 nails to the lower end of the ceiling frame 2a. A ceiling finishing material 5 is stretched over the ceiling frame body 4. Therefore, although the floor sound on the upper floor is transmitted to the hanging fixture 9 via the frame support member 2, it is absorbed by the shock absorbing material 3 and is not transmitted to the ceiling frame 4. In the embodiment shown in FIG. 3, a U-shaped impact buffer 3 is interposed on the inner periphery of a field edge 2b serving as a frame support member 2, and a metal U-shaped hanging tool 9 is held upside down. The hanging tool 9 is made to straddle and hold the ceiling edge 2b, and both side pieces 9a of the hanging tool 9 are fixed to the ceiling edge 8, which is the ceiling frame body 4, by driving 10 nails to support the ceiling edge 8. A ceiling finishing material 5 is stretched over this ceiling edge 8. Therefore, although the sound from the floor above is transmitted to the frame support member 2, the shock absorbing material 3
It will not be absorbed into the hanger 9 and transmitted to the ceiling frame 4. The ceiling edge 8 and the ceiling finishing material 6 may be integrated at the site. In any of the above embodiments, the impact cushioning material 3 is made of glass wool with a density of 48 to 160 Kg/m ³ , preferably 64 to 96 Kg/m ³ and whose outer surface is impregnated with resin to form an outer skin. Can be suitably adopted. In addition to glass wool, rock wool felt, fiber mat, fiber board, etc. can also be used. Also, the frame support member 2
Other materials such as joists can also be used.

[Effect of idea]

In the present invention, a frame support member is attached to the floor structure that holds the floor above, and either the frame support member or the ceiling frame is attached to the inner periphery using a substantially U-shaped hanging tool. Since the ceiling frame is supported by the frame support member by interposing the shock absorbing material and fixing both sides of the hanger to the other side, the sound from the floor above is transmitted through the frame support member. The impact is absorbed by the shock absorbing material interposed on the inner periphery of the hanging fixture and is not transmitted to the ceiling frame or ceiling finishing material, and the shock absorbing material is formed approximately in a U-shape. Therefore, a shock absorbing material can be interposed between the inner periphery of the approximately U-shaped hanging tool and the outer periphery of the frame support member and the ceiling frame.
The shock absorbing material can reliably prevent the hanging tool from coming into contact with the frame support member or the ceiling frame, and can ensure soundproofing.
