Description

  The present invention relates to a room-to-room soundproofing construction method that can provide sound insulation between rooms and is easy to construct.

2. Description of the Related Art A double ceiling is known in which a crosspiece is formed under a ceiling slab formed from a concrete base via a hanging bracket, a ceiling base is formed, and a ceiling material is disposed on the ceiling base. In this double ceiling, a sound insulation wall is provided between the ceiling slab and the ceiling material in order to prevent sound from propagating to other rooms through the space behind the ceiling (for example, Patent Documents). 1).
JP 2003-155791 A

  However, since ducts, piping, and wiring are generally installed on the back of the ceiling, in order to ensure sound insulation, the sound insulation wall is cut out so that the duct, piping, and wiring penetrate, and sound leakage occurs at the notched portions. It was necessary to seal so as not to occur. For this reason, there is a problem in that the trouble at the construction site increases and the soundproof performance varies depending on the construction method.

  This invention is made | formed in view of such a situation, and makes it a subject to provide the sound insulation construction method between rooms which can maintain the sound insulation performance equivalent to the conventional sound insulation wall, making construction simple.

In order to solve the above problems, the present invention provides a plate-like sound absorbing material on a partition wall panel fixing rail in a ceiling base disposed in advance, so as to straddle between the rails. Sound insulation is required so that one end of the material is placed above the partition wall panel via a crosspiece or abuts against the surface material of the partition wall panel so as not to disturb the duct, piping, and wiring installed on the back of the ceiling It is characterized by being partially arranged corresponding to the upper part of the partition wall panel .

  According to the present invention, it is possible to attenuate sound coming into the back of the ceiling with the sound absorbing material and make the sound insulation between rooms equal to that of a conventional sound insulation wall. Sound insulation between rooms can be realized without any obstacles due to ducts, piping and wiring installed in the ceiling.

  FIG. 1 is a cross-sectional view showing one embodiment of the inter-room soundproofing construction method of the present invention.

  A support leg 2 is erected on a floor slab 1 formed from a concrete base, and a floor base material 3 is placed on the support leg 2 to form a double floor 4. A floor finish 5 is disposed on the surface of the double floor 4. The ceiling base 6 is formed after the construction of the double floor 4.

  The ceiling foundation 6 is formed below the ceiling slab 7 formed from the concrete foundation via suspension bolts 8. The ceiling base 6 is formed by a combination of bars 9 arranged vertically and horizontally at a predetermined pitch. The crosspiece 9 is generally made of a wood material such as LGS or LVL.

  After the ceiling base 6 is formed, the partition wall panel 10 is fixed to the double floor 4 and the ceiling base 6 and the floor plan is performed. For example, as shown in FIG. 2, the partition wall panel 10 is fixed to the upper horizontal frame 11 of the partition wall panel 10, and the side surface of the partition wall 12 is fixed to the side surface of the rail 9. It is carried out by abutting on and connecting with a fixture 13 such as a nail.

  The partition wall panel 10 has two face members 14 such as gypsum board disposed on the left and right sides and attached to each other. In order to increase the strength and improve the sound insulation between the rooms, two face materials 14 are provided. The face material 14 does not necessarily have to be two on one side, and the number of face materials can be set appropriately depending on the thickness or the like. One sheet can also be used. A baseboard 15 is disposed at the lower end of the partition wall panel 10 as shown in FIG.

  A sound absorbing material 17 is disposed above the partition wall panel 10 where sound insulation is required before the ceiling board 16 is attached. The sound absorbing material 17 is a plate-like member, and is formed from an appropriate material that absorbs sound such as glass wool. The sound absorbing material 17 is bridged over a crosspiece 9 that forms the ceiling base 6, and one end thereof is disposed above the partition wall panel 10. Since the sound absorbing material 17 is arranged so as to straddle between the crosspieces 9 in this way, in other words, the width of the sound absorbing material 17 is larger than the pitch of the crosspieces 9 forming the ceiling base 6, so that the ceiling board 16 is pasted. There is no need to work on the fall prevention. Moreover, although the sound absorbing material 17 is plate-shaped, it does not necessarily have to have a sufficiently high rigidity, and a portion that protrudes from the crosspiece 9 by hanging over the crosspiece 9 may hang downward.

  After the sound absorbing material 17 is disposed, the ceiling board 16 is disposed. As shown in FIGS. 1 and 2, the ceiling board 16 is disposed such that the end abuts against the partition wall panel 10 so that no gap is formed between the ceiling board 16 and the partition wall panel 10.

  If there is a sound source in the room on the left side in FIG. 1, since the ceiling board 16 is generally thinner than the face material 14 disposed on the partition wall panel 10, the sound is likely to be transmitted to the back of the ceiling. The transmitted sound is attenuated by the sound absorbing material 17 and is less likely to leak into the room on the right. Similarly, if there is a sound source in the right room, the sound transmitted to the back of the ceiling is attenuated by the sound absorbing material 17 and hardly leaks into the room on the left. Thus, the sound transmitted around the ceiling is suppressed by a simple method, and soundproofing between rooms is realized. In addition, the arrangement of the sound absorbing material 17 does not obstruct the ducts, piping, and wiring installed on the back of the ceiling, so there is no need to form notches for penetration or seal around the notches. Are better. Waste material at the construction site is also reduced.

  FIG. 3 is a sectional view showing another embodiment of the inter-room soundproofing construction method of the present invention.

  This embodiment is different from the embodiment shown in FIG. 1 in that the crosspiece 9 that forms the ceiling base 6 is orthogonal to the partition wall panel 10, and the rest is the same as the embodiment shown in FIG. 1. It is.

  In this way, even when the crosspiece 9 is orthogonal to the partition wall panel 10, the plate-like sound absorbing material 17 is arranged so as to span the juxtaposed crosspiece 9, and one end of the crosspiece 9 is placed above the partition wall panel 10. Arranged through. Sound transmitted from the ceiling board 16 to the back of the ceiling is attenuated by the sound absorbing material 17 and is prevented from leaking into the adjacent room. Sound transmitted around the ceiling is suppressed by a simple method, and soundproofing between rooms is realized. Moreover, the arrangement of the sound absorbing material 17 does not interfere with ducts, piping, and wiring installed on the back of the ceiling, and is excellent in workability. Waste material at the construction site is also reduced.

  FIG. 4 is a cross-sectional view showing another embodiment of the inter-room soundproofing construction method of the present invention.

  In the present embodiment, a soundproofing method between rooms having different ceiling heights is shown. If a duct or a ventilation fan is installed behind the ceiling of a room with a low ceiling, such as a toilet, washroom, or bathroom, the sound absorbing material may not be installed above the room. The plate-like sound-absorbing material 17 is disposed on the back of the ceiling of a neighboring room with a high ceiling, for example, a bedroom. As in the embodiment shown in FIG. 1, the sound absorbing material 17 is stretched over a crosspiece 9 that forms the ceiling base 6, and one end thereof is disposed above the partition wall panel 10. Sound generated in a room with a low ceiling height and transmitted from the ceiling board 16 to the back of the ceiling is attenuated by the arranged sound absorbing material 17 and is prevented from leaking into the adjacent room. Sound transmitted around the ceiling is suppressed by a simple method, and soundproofing between rooms is realized. Moreover, since the sound absorbing material 17 is disposed irrespective of a duct, a ventilation fan, or the like, it has excellent workability.

  FIG. 5 is a sectional view showing another embodiment of the inter-room soundproofing construction method of the present invention.

  In the present embodiment, unlike the embodiment shown in FIG. 4, a plate-like sound absorbing material 17 is disposed above a room having a low ceiling height such as a Japanese-style room or a bedroom via a bar 9. The sound absorbing material 17 is bridged on the crosspiece 9 and one end thereof is brought into contact with the face material 14 of the partition wall panel 10. In this embodiment, this is also common to the embodiment shown in FIG. 4, but because it is additionally attached, the upper end portion of the face material 14 on the room side with a low ceiling height is used to dispose the crosspiece 9. The outer face material 14 is cut away. In the present embodiment, the sound absorbing material 17 is brought into contact with the upper end portion of the inner face material 14 that is not cut out. Sound generated in a room such as a living room / dining room with a high ceiling and transmitted from the ceiling board 16 to the back of the ceiling is attenuated by the arranged sound absorbing material 17 and is prevented from leaking into the adjacent room. Sound transmitted around the ceiling is suppressed by a simple method, and soundproofing between rooms is realized. Moreover, the arrangement of the sound absorbing material 17 does not interfere with ducts, piping, and wiring installed on the back of the ceiling, and is excellent in workability. Waste material at the construction site is also reduced.

  Actually, in the embodiment shown in FIG. 1, when a single gypsum board that is not additionally attached is disposed as the face material 14 and when a conventional sound insulation wall is provided (no additional attachment), a sound absorbing material is provided on the back of the ceiling. We compared the soundproofing performance between rooms when there is no (no additional sticking). A glass wool plate having a width of about 400 mm and a thickness of about 50 mm was used as the sound absorbing material. As shown in FIG. 6, it is confirmed that the embodiment of the present invention has substantially the same soundproofing performance as that in the case of providing a conventional sound insulating wall. Even when ducts, piping, and wiring are installed on the back of the ceiling and it is difficult to dispose a sound insulation wall, it is possible to realize sound insulation between rooms by disposing a sound absorbing material at a predetermined position. In the case of a partition wall panel in which two gypsum boards are arranged and pasted, it is understood that the sound insulation is better.

  In the present invention, the room arranged by the partition wall panel includes a corridor.
