Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sound absorbing structure for a large mountain-shaped roof that has a simple structure, can be easily constructed, and has excellent sound absorbing effects.

[Conventional technology and its problems]

Conventionally, sound absorption treatment on the indoor side of a large chevron roof has been carried out by attaching a heat insulating board that also serves as a sound absorbing material, or by installing sound absorbing properties between the heat insulating board and the sloped side of the indoor side of the large chevron roof. The existing cotton-like glass wool was inserted.

However, when the above structure is used in buildings such as gymnasiums and indoor ball game facilities, if the ball collides with the ceiling during a ball game, the insulation board may be damaged. Since it is inserted between the glass wool and the sloped sides of the roofing material, problems such as the sound absorption properties of glass wool are not fully utilized.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above problems, the inventor has developed the present invention by polymerizing a sound absorbing material made of relatively low-density glass wool into a substantially flat plate and a relatively thin heat insulating plate material. The inner wall panel material is glued to form an inner wall panel material 7, and this inner wall panel material is attached approximately parallel to both inclined sides on the indoor side of the large-sized chevron roofing material, so that the insulation board material side of the inner wall panel material faces the inclined sides. By arranging large chevron-shaped roofing materials such as these in parallel and connecting them to create a sound-absorbing structure, the sound-absorbing properties of glass wool can be fully utilized to protect the insulation board materials from impact. This is extremely simple and solves the above problems.

〔Effect of the invention〕

In the present invention, the inner wall panel material 7 is formed by polymerizing and adhering a sound absorbing material 7b made of relatively low-density glass wool into a substantially flat plate shape and a relatively thin section board material 7a. The insulation board material 7a of the inner wall panel shrine 7 is installed approximately parallel to the double-ended oblique side 2.2 on the indoor side of the large-sized chevron roofing material A.
Strain the G so that the side faces the sloped side 2, and arrange the large chevron roofing materials in parallel and adjacent to each other (11 pieces to 1!!
! By adopting a sound-absorbing structure with a large chevron-shaped roof, firstly, an excellent sound-absorbing effect can be obtained, and secondly, the inner wall panel material 7 can be made sufficiently durable against impact. Thirdly, the inner wall panel material 7
can obtain excellent insulation effect, and fourthly, inner wall panel material 7
has the advantage of being resistant to staining.

To explain these effects in detail, firstly, in the present invention, glass wool, which is a TV material with excellent sound absorption properties and has a relatively low density (approximately 20 kg/n? to approximately 50 kg/m), is used as the sound absorbing material 7b. This is used as the inner wall panel material 7 by polymerizing and bonding this with a board-like heat insulating plate material 7a. This inner wall panel + 47 is attached so that the danshi board shrine 7a side faces the (about hypotenuse 2) of the large chevron roofing material A, and the sound absorbing material 7b faces the indoor side, so the sound absorbing material of glass wool The characteristics are fully utilized and a good sound absorption effect can be obtained.

Furthermore, in the present invention, since the inner wall panel material 7.7 is attached approximately parallel to the oblique sides 2, 2 on the indoor side of the large-sized chevron-shaped roof material A, the sound partially reflected by the inner wall baffle material 7 on one side is , the sound is absorbed by the inner wall panel material 7 on the side opposite to the inner wall panel material 7, and the sound reflected there can be made extremely small. A large mountain-shaped roof with a series of such mountain shapes has the great effect of effectively absorbing noise from inside (indoors).

Second, in the present invention, glass wool is made into a substantially flat plate shape to form the sound absorbing material 7b, and this and a board-shaped heat insulating board material 7a are polymerized and bonded to form the inner wall panel material 7, so that the sound absorbing material 7b faces the indoor side. Since the inner wall panel material 7 is attached to the large-sized chevron-shaped roof material A, if the present invention is used in a gymnasium or an indoor ball game facility, the sound absorbing material 7b (glass wool) can absorb the impact when a ball collides with the ceiling during a ball game, etc. This can protect the heat insulating board material 7a from impact, and the inner wall panel material 7 can be made extremely durable.

Thirdly, in the inner wall panel material 7, the glass wool used as the sound absorbing material 7b has properties obtained as a heat insulating material, and the synergistic effect between this and the heat insulating properties of the board-shaped heat insulating board material 7a makes it extremely effective. You can get superior insulation effect.

Fourthly, the inner wall panel material 7 has a two-layer structure of a heat insulating board material 7a and a sound absorbing material 7b, and the heat insulating board material 7a has almost no air permeability. Therefore, the inner wall panel material 7 blocks the flow of air in the room. For this reason, even if the sound absorbing material 7b is made of low-density glass wool and is in the form of coarse fibers, air will not circulate, and dirt and dust in the air will be difficult to adhere to the sound absorbing material 7b, and the inner wall panel material 7 will be It can be relatively stain-resistant.

In addition, as shown in FIGS. 1 and 2, if cotton-like glass wool is filled as a heat insulating material 11 between the inner wall panel material 7 and the inclined side 2 to the large-sized chevron roof material, the inner wall panel material 7 With the addition of the insulation performance of It is possible to reduce the amount of ?Ji 77 applied to the inner wall panel material 7.
