Description

[Detailed Description of the Invention] The object of the present invention is to use a sound insulation and sound absorption construction method and special stone panels used therein for partition walls and ceiling surfaces of rooms related to music and acoustics, such as music practice rooms, recording studios, and audio listening rooms. It was developed as

These rooms are required to ensure sound insulation between rooms, appropriately control indoor sound absorption, etc., and building with these panels is effective for both.

The first panel is made of gypsum board with a thickness of, for example, 12 mm.
It is formed into a triangular shape as shown in FIG.

Several types of combination methods can be considered depending on the purpose of use. For example, when combined as shown in Figure 3, it becomes a sound insulating partition, Figure 4 shows an external wall sound insulation structure of a wooden house, Figure 5 adds sound absorbing panels, etc., and Figure 6 shows a space inside the panel. Sound insulation and sound absorbing panel walls.

Conventionally, when relatively large sound insulation (transmission loss) performance is required, materials with high areal density and denseness are used. Furthermore, as shown in FIG. 8, a relatively high transmission loss can be obtained by independently supporting vibration-insulated panels, and this is often used in dry construction methods.

However, in order to construct a structure like the one shown in Figure 8, studs must be installed independently on both sides of the panels, and they must be insulated to prevent the formation of sound bridges. This generally requires large distances between panels and increases wall thickness.

This means that when used as a partition wall in an apartment complex or a hotel, it is not preferable because it reduces the effective area of the floor.

Furthermore, as shown in FIG. 9, when a sound-absorbing interior is applied to this partition wall, it is necessary to prepare a new base, and the wall thickness becomes even thicker.

Compared to these conventional construction methods, the special stone panel of the present invention is self-supporting, and does not require any base material such as studs other than the mounting members above and below the panel. Furthermore, as shown in Figure 3, the panels are built in double layers with an interval of about 10 mm, so it is possible to obtain the same effect as independent support.

Also, as shown in Figure 5, it is possible to directly attach a sound absorbing panel (glass wool, rock wool sound absorbing board, etc.) that has an air layer behind it.

Therefore, the present invention has the following advantages compared to conventional construction methods.

Since the panel itself can stand on its own, it can be constructed with fewer steps (fewer types of work).

When used as a sound insulating wall for a partition, the wall thickness can be thinner than before.

It is certain that performance such as sound insulation and sound absorption properties will be achieved.

Great sound insulation performance can be obtained by incorporating it into the outer wall of a wooden house.

The structure and operation of the triangular special stone panel of the present invention will be explained.

For example, the triangular shaped special stone panel is 12cm thick.
The base of the stone board (Fig. 1) is 400 mm, and the oblique side is
221, the basic plan is to build it into a triangle with a 130 degree angle at the top. The top part contains a base (Fig. 2 A) for installing the sound absorbing panel.
There are PVC protection rods (Figure 2 B) in the remaining two folded corners to protect them from damage. The air gap is filled with glass wool 32 to prevent resonance transmission in the low frequency range.
Kg/m ³ (Figure 2 C).

The panels will be installed after marking them out on site.
Screw the mounting components to the ceiling and floor. A special triangular stone panel of the present invention is sandwiched and fixed on top of this, and the joint portion is sealed with caulking or sound insulating tape.

Seals are also applied to the upper and lower edges as necessary.

After this work, a 9mm thick plaster board is applied over the surface to create a finished surface.

In principle, the triangular special stone panel of the present invention can be cut to any height and width. From this point on, you can create a wall of any size using two or three types of panels. This is also a major feature of this special stone panel.

When using the triangular special stone panel of the present invention as a sound-insulating partition, the most standard configuration is as shown in FIG. 3.

The transmission loss in this case is 44 dB at f=500 Hz, which is equivalent to a concrete wall with a thickness of about 100 mm.

When a very high degree of sound insulation is required, a floating structure consisting of a fixed side primary sound insulation layer and a secondary sound insulation layer insulated from the fixed side primary sound insulation layer is adopted as shown in FIG.

When the special triangular stone panel of the present invention is used in such a structure, it is very easy to construct because it does not require a base, and it also has good performance as a floating structure.

When creating a floating structure, first the structure slab (7th
A floating floor (Fig. 7) supported by glass wool or anti-vibration rubber is constructed on top of the floating floor (Fig. 7), and then a ceiling supported by anti-vibration rubber is constructed using special plaster panels for the ceiling. (Figure 7) Finally, a floating structure room is created by attaching special stone panels on the wall supported by the floating floor and special stone panels for the ceiling.

In this case, there is no need for any base material to prevent warping between the primary sound insulation layer and the special wall stone panel, and they can be supported completely independently, making it an ideal floating structure compared to conventional construction methods (with a base). It becomes a structure.

Sound absorbing panels (glass wool panels,
The rock wool sound-absorbing panels (rock wool sound absorbing boards) are attached to the top portions of the outer ends of each of the special rock wool panels arranged in series as shown in FIG. Generally used sound absorbing materials have different frequency characteristics of sound absorption coefficient depending on the thickness of the air layer behind them, and the thicker the air layer, the higher the sound absorption coefficient up to the low frequency range.

When a sound absorbing panel is attached to the triangular special stone panel of the present invention, an air layer that continuously changes from 0 to 95 mm is created behind the sound absorbing material, making it possible to absorb sounds up to relatively low frequencies.

According to conventional construction methods, it is not possible to secure an air layer without constructing a base for the sound-absorbing wall separately from the sound-insulating wall, but with the triangular special stone panel of the present invention, there is no need for any base. A sound-absorbing wall with an air layer can be created.

According to the present invention, when constructing a room related to acoustics or music, it is possible to control both sound insulation and sound absorption at the same time. Previously, the solution was to create a combination of different wall surfaces. In the case of the newly developed special stone panel, it is possible to construct a wall of any size with a single member. Moreover, this panel can be combined in various ways, and it is relatively easy to construct a floating structure, which was difficult to install and support in the past. Additionally, it has the advantage of being able to achieve the same sound insulation performance with a smaller wall thickness than conventional double walls.

In an embodiment of the present invention, a special stone panel having a triangular shape having triangular sides 1, 2, and 3 is formed by bending a plaster board as shown in FIG. As shown in Figure 4, the convex part of the other special masonry panel is placed in the concave part formed by arranging the special masonry panels with a gap 4 between them, and the partition wall or the external sound insulation wall of the wooden house shown in Figure 4 and the convex part are placed on the outside for sound insulation. Build panel walls and ceilings, etc.
