Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a ceiling structure for a so-called easily assembled soundproof room that is installed indoors to prevent noise pollution by installing a piano or the like therein.

(Prior Art and Its Disadvantages) A conventional soundproof room a of this type is usually installed at a corner of a room L, as shown in FIGS. 6 and 7. Then, in the upper part of the soundproof wall member b of the soundproof room a that is not in contact with the wall W of the room L, two through holes are provided as far apart as possible from each other, and a ventilation fan c is attached to one of these holes to exhaust the air. One hole d was used, and the other one was used as an intake hole e to ventilate the inside of the soundproof room a. In addition, in FIGS. 6 and 7, R indicates the ceiling of room L, f indicates the door of soundproof room a,
Similarly, g indicates a ceiling member, and h similarly indicates a floor member.

However, in such a conventional soundproof room a, the sound in the soundproof room a easily flows out into the room L through the exhaust hole d and the intake hole e, and the noise in the room L easily flows into the soundproof room a. The problem was that the noise from the ventilation fan C could be heard both in room L and in the soundproof room.

Therefore, as shown in FIG. 8, it is conceivable that the entire ceiling member g has a duct structure. That is,
A ventilation fan c is provided on the outer upper surface i of the ceiling member g, and the ventilation fan c sends the air in the soundproof room a through the ceiling member g to the room L, and at the same time sends the air from the room L into the soundproof room a through the ceiling member g. Let's send it in.

By doing this, it is thought that the outflow of sound from inside the soundproof room a to the room L and the inflow of noise from the room L into the inside of the soundproof room a are greatly improved.

However, if the ceiling member g is entirely constructed as a duct, the ceiling member g itself needs to be quite thick, so the ceiling height j in the soundproof room a becomes quite low. Furthermore, since the ventilation fan c is installed on the outer upper surface i of the ceiling member g, it is inevitable that the distance k between the ceiling R of the room L and the outer upper surface i of the ceiling member g of the soundproof room a be equal to the thickness of the ventilation fan c. This also means that the ceiling height j in the soundproof room a becomes quite low. This gives the people in the soundproof room a a very cramped and oppressive feeling.

(Purpose of the invention) This invention aims to improve the ventilation efficiency of the soundproof room, and also allows for a sufficient ceiling height in the soundproof room so that the people in the soundproof room do not feel cramped or oppressed. The present invention provides a ceiling structure for a soundproof room.

First, the structure of the exhaust duct ceiling member 1 shown in FIG. 1 will be explained.

This exhaust duct ceiling member 1 consists of a top plate 1a, a bottom plate 1b, a left side plate 1c, a right side plate 1d, a front plate 1e, and a rear plate 1f, and a partition plate 1g is provided inside thereof. 1g forms two rooms, a left room 1h and a right room 1i. These two rooms 1h and 1i are communicated at the rear, and a ventilation fan M is installed in contact with the top plate 1a, the bottom plate 1b, the left side plate 1c, and the partition plate 1g in the rear part of the left room 1h. As the ventilation fan M, an axial ventilation fan is suitable in order to reduce static pressure and increase air volume. Further, an external air exhaust hole 1j is provided in the upper part of the left side plate 1c near the front plate 1e, and an internal air exhaust hole 1k is provided in the lower part of the right side plate 1d near the front plate 1e. Ta. A soundproofing material (not shown) such as glass wool is pasted inside the exhaust duct ceiling member 1 to the extent that it does not increase the static pressure and does not increase the amount of sound and noise passing through inside and outside the soundproofing room. There is.

In addition, in FIG. 1, support bars 1m and 1n are horizontally protruded from the center of each outer surface of the front plate 1e and the rear plate 1f.
As shown in FIG. 4, this is for supporting the exhaust duct ceiling member 1 when it is dropped into the inner surface of the wall member 4 of the soundproof room. In addition, right side plate 1
The support bar 11 horizontally protruding from the center of the outer surface of d is
Similarly, as shown in FIG. 4, this is for supporting the left side surface of the soundproof ceiling member 2 whose front and rear ends are placed on the wall member 4. FIG. 2 shows the soundproof ceiling member 2.
The thickness of this soundproof ceiling member 2 is approximately half that of the exhaust duct ceiling member 1 shown in FIG. is filled. In addition, 2aa in FIG. 2 indicates a notch corresponding to the support bar 11 of the exhaust duct ceiling member 1, as shown in FIG. 4, and 2ab indicates a notch corresponding to the support bar 31 of the intake duct ceiling member 3, which will be described later. shows.

FIG. 3 shows the air intake duct ceiling member 3. The internal structure of this intake duct ceiling member 3 is the same as that of the exhaust duct ceiling member 1 shown in FIG. 1, with the ventilation fan M removed. That is, this intake duct ceiling member 3 consists of a top plate 3a, a bottom plate 3b, a left side plate 3c, a right side plate 3d, a front plate 3e, and a front plate 3f, and a partition plate 3g is provided inside. Two rooms, a left room 3h and a right room 3i, are formed by the board 3g. These 2
The two rooms 3h and 3i are connected at the front. An external air intake hole 3j is provided in the upper part of the right side plate 3d near the rear plate 3f, and an internal air intake/exhaust hole 3k is provided in the lower part of the left side plate 3c near the rear plate 3f.
Similar to the exhaust duct ceiling member 1, a soundproof material (not shown) such as glass wool is pasted inside the intake duct ceiling member 3.

In addition, in FIG. 3, support beams 3m and 3n that are horizontally protruding from the center of each surface of the front plate 3e and the rear plate 3f are as follows:
As shown in FIG. 4, this intake duct ceiling member 1
This is for supporting when it is dropped into the inner surface of the wall member 4 of the soundproof room. Further, the support bar 31 horizontally installed in the center of the outer surface of the left side plate 3c is also the fourth support bar 31.
As shown in the figure, this is for supporting the right side of the soundproof ceiling member 2 whose front and rear ends are placed on the wall member 4.

FIG. 4 is a sectional view of the soundproof room A, and is an example in which one soundproof ceiling member 2 is used. In the figure, 4 indicates a wall member, the rear indicates a floor member, and T indicates an exhaust duct ceiling member 1, a soundproof ceiling member 2, and an intake duct ceiling member 3.
This figure shows a ceiling formed by installing the and in parallel horizontally in order. The outer upper surface Ta of this ceiling T is flat 2
The soundproof room A can be installed as tightly as possible up to the height of the ceiling R of the room L. , Q indicates a duct ceiling member support that is hooked to the upper end surface of the wall member 4 and is vertically installed along the wall member 4 within the soundproof room Aa. Further, Wa indicates an interior wall member, and F indicates a carpet.

Although FIG. 4 shows an example in which one soundproof ceiling member 2 is used, two or more soundproof ceiling members 2 may be used depending on the size of the soundproof room A.

In addition, in FIGS. 1, 3, and 4,
The internal air exhaust hole 1k of the exhaust duct ceiling member 1 is provided on the right side plate 1d of the exhaust duct ceiling member 1, and the internal air intake and exhaust hole 3k of the air intake duct ceiling member 3 is provided on the right side plate 1d of the exhaust duct ceiling member 1.

may be provided.

FIG. 5 shows a plan view of a room L in which a soundproof room A is installed. As you can see from Figure 4 and this Figure 5,
Exhaust duct ceiling member 1 equipped with ventilation fan M
It can be seen that a space S corresponding to the thickness of the wall member 4 of the soundproof room is formed in the front part of the external air exhaust hole 1j, and there is no problem in exhausting the air.

(Effects of the invention) As described above, according to this invention, the ventilation efficiency is greatly improved compared to the conventional method, and the noise prevention effect of the ventilation fan is also significantly improved. Furthermore, the exhaust duct ceiling members and the intake duct ceiling members were somewhat thicker, but since these duct ceiling members were located at the left and right ends of the soundproof room, the overall ceiling height in the soundproof room was lowered. Rather, the effect is that the people in the soundproof room do not feel cramped or oppressed.
