Description

  The present invention relates to a sound insulation panel that forms a field wall and a partition wall provided inside a building.

  The boundary walls and partition walls in the panel method may be formed by sound insulation panels. This sound insulation panel is known to have a gypsum board, which is a sound insulation material, attached to a frame assembled with a core material, and a sound absorbing material such as glass wool is filled in the frame body to which this gypsum board is attached. (See Patent Document 1).

By the way, the sound insulation performance varies depending on the frequency range, and the sound absorbing material such as glass wool can efficiently absorb the sound wave in the high frequency range, but has little effect on the sound wave in the low frequency range. In order to insulate the sound in this low frequency range, it is necessary to increase the surface density of the wall panel according to the law of mass, so multiple gypsum boards of the sound insulation panel are stuck together or thicker than usual. I was stuck.
JP 7-158179 A

  However, when the gypsum board of the sound insulation panel is made thick or a plurality of gypsum boards are stacked, the total thickness of the panel becomes thicker than other panels, and there is a problem that the construction at the site becomes complicated. In addition, if the width of the core material that forms the frame is changed without changing the thickness of the gypsum board of the sound insulation panel, a new type of core material is manufactured because the size of the core material used in other panels does not match. There must be. Therefore, there has been a problem that the types of creative members produced at the factory increase, and the manufacturing cost increases.

  An object of the present invention is to suppress manufacturing costs and facilitate construction in a sound insulation panel that forms a field wall or a partition wall provided inside a building.

In order to solve the above-described problems, the invention described in claim 1 includes, as shown in FIG. 1, for example, a frame 2 formed by assembling a vertical frame 2a and a horizontal frame 2b into a rectangular frame, and the frame. A face material (for example, plywood 4) provided on both sides of
Reinforcing bars 3 are provided vertically and horizontally in the frame 2, and the face material 4 is fixed to the frame 2 and the reinforcing bars 3,
A hollow portion surrounded by at least one surface material (for example, plywood 4) of the double-sided material (for example, plywood 4) by the reinforcing bar member 3, the frame 2, and the surface material (for example, plywood 4). Each is characterized in that one hole 5 communicating with the hollow portion is provided close to the vertical rod side 2a .

According to the first aspect of the present invention, the face material (for example, the plywood 4) is provided with the frame body 2 formed by assembling the vertical frame material 2a and the horizontal frame material 2b into a rectangular frame shape, and the frame body 2. One hole 5 communicating with the hollow portion surrounded by the formed face material (for example, plywood 4) and the reinforcing bar member 3 is provided close to the vertical rod side 2a . Here, the sound wave emitted from the sound source travels in the air and is transmitted to the face material (for example, the plywood 4) to become a vibration wave. At this time, the vibration wave is transmitted through the vertical frame member 2a and the horizontal frame material 2b, as well as the frame member 2 of the face material (for example, the plywood 4) and the portion where the reinforcing bar member 3 is not fixed. And the part to which the reinforcing bar 3 is fixed serves as a fixed end, and a part of the vibration wave is reflected. Therefore, when the part to which the frame 2 of the face material (for example, the plywood 4) is not fixed is a rectangle, vibration waves that travel the same distance increase. Accordingly, the wavelengths of the vibration waves become equal, and the sound generated from the face material (for example, the plywood 4) is amplified and increased. However, by providing the hole 5 in the face material (for example, the plywood 4), the hole 5 serves as a free end, and the vibration wave transmitted through the face material (for example, the plywood 4) travels through various distances and is reflected. Therefore, it becomes difficult to match the wavelengths of the vibration waves, and the sound generated from the face material (for example, the plywood 4) can be suppressed. Therefore, the sound insulation performance of the sound insulation panel 1 is improved.

  Moreover, since it is not necessary to make the sound insulation panel 1 thick as in the prior art, the total thickness of the sound insulation panel 1 can be adjusted to the total thickness of other panels, and construction on the site becomes easy. Furthermore, since the vertical gutter material 2a and the horizontal gutter material 2b which form the frame 2 of the sound-insulating panel 1 can be diverted from those used for other panels, the manufacturing cost can be reduced.

In addition , reinforcing bars 3 are provided in the frame 2 vertically and horizontally, and face materials (for example, plywood 4) are provided for each hollow portion surrounded by the reinforcing bars 3, the frame 2, and the face material (for example, plywood 4). ) Is provided with a hole 5. Therefore, the intensity | strength with respect to the load concerning the sound-insulation panel 1 can be raised, and it can prevent that the sound-insulation panel 1 deform | transforms with a load, or is destroyed.

The invention according to claim 2 is characterized in that, in the sound insulation panel 1 according to claim 1, for example, as shown in FIG. 1, the face material (for example, plywood 4) is a plywood 4.

According to the invention described in claim 2 , since the face material (for example, the plywood 4) is the plywood 4, the sound insulating property of the sound insulating panel 1 is improved. Moreover, since the plywood 4 is inexpensive, the manufacturing cost of the sound insulation panel 1 can be suppressed.

According to a third aspect of the present invention, for example, as shown in FIG. 1, in the sound insulation panel 1 according to the first or second aspect , the frame 2 is filled with a sound absorbing material (for example, glass wool 6). It is characterized by being.

According to the invention described in claim 3 , since the sound absorbing material (for example, glass wool 6) is filled in the frame 2 of the sound insulating panel 1, the sound that is not sound-insulated by the face material (for example, the plywood 4). Is absorbed by a sound absorbing material (for example, glass wool 6). Therefore, the sound insulation performance of the sound insulation panel 1 is improved.

According to a fourth aspect of the present invention, for example, as shown in FIG. 1, in the sound insulation panel 1 according to the third aspect , the sound absorbing material (for example, glass wool 6) is glass wool 6.

According to the invention described in claim 4 , since the sound absorbing material (for example, glass wool 6) is the glass wool 6 having heat insulation properties, the sound insulation performance of the sound insulation panel 1 is improved and the heat insulation performance is improved.

According to the present invention, the face material is provided with one hole 5 communicating with the hollow portion surrounded by the frame body 2 and the face material provided on the frame body 2 and the reinforcing bar material, close to the vertical saddle material side. Therefore, since the hole serves as a free end and the vibration waves transmitted through the face material travel and are reflected at various distances, the wavelengths of the vibration waves are not matched and the sound generated from the face material can be suppressed. . Therefore, the sound insulation performance of the sound insulation panel 1 is improved. Moreover, the total thickness of the sound insulation panel can be matched with the total thickness of other panels, and construction on the site becomes easy. Furthermore, since the vertical gutter material and the horizontal gutter material which form the frame body of a sound insulation panel can divert what is used for another panel, manufacturing cost can be held down.
