Description

The present invention relates to a method of installing a soundproof room, a soundproof panel, and an assembly type soundproof room.

Soundproof rooms formed by connecting soundproof panels are installed in various places. The soundproof room is installed via a vibration-proof material formed of rubber, for example, between the floor and the floor so that the vibration from the floor of the installation location is not transmitted to the soundproof room or the vibration in the soundproof room is not transmitted to the floor. (For example, Japanese Patent Application Laid-Open No. 2000-17868).

The soundproof room is being considered to be used not only inside a building but also in a transport aircraft such as a vehicle, a ship, or an aircraft to provide a living room with reduced noise level and improved comfort. For example, in recent years, the International Maritime Organization (IMO) has tightened noise regulations for living spaces and control spaces of ships. Therefore, installing a soundproof room inside the ship is considered to be a realistic solution.

When installing a soundproof room in a transport aircraft such as a ship, it is necessary to fix the soundproof room so that the soundproof room does not shift due to vibration or shaking of the transport aircraft. Therefore, it is desired to fix the soundproof room and the structure at the installation location with a fixture having anti-vibration properties.

On the other hand, in a transport aircraft, it is required to improve the space utilization efficiency, so it is desirable that the soundproof room is installed with the space between the wall and the pillar and the gap between the adjacent soundproof rooms as small as possible. However, in order to fix the soundproof room to the structure, it is necessary to secure a sufficient work space between the soundproof room and the structure, so that a dead space is generated around the soundproof room. There is an inconvenience.

Japanese Unexamined Patent Publication No. 2000-17868

In view of the above inconvenience, the present invention presents a method of installing a soundproof chamber capable of fixing the soundproof chamber to the structure with a relatively small gap, a soundproof panel capable of fixing the soundproof chamber to the structure with a relatively small gap, and an assembly type soundproof chamber. The challenge is to provide.

The invention made to solve the above problems is a method of installing a soundproof chamber in which a soundproof chamber formed of a plurality of sound insulation panels is fixed to a structure at an installation location, wherein the sound insulation panel and the structure are fixed. A fixing member fixed to one side and having a screw hole extending in the normal direction of the sound insulation panel, and a shaft body provided with an engagement structure that engages with the screw hole and engages a tool with an end portion on the sound insulation panel side. The soundproof chamber is supported by a pressure contact mechanism having a sound insulation panel and a vibration isolation member that is supported by the shaft body and is pressed against the other side of the structure as the distance from the fixing member increases with the rotation of the shaft body. This is a method of installing a soundproof chamber, which comprises inserting a tool into a through hole formed in advance in the sound insulation panel to rotate the shaft body from the inside of the sound insulation panel.

The soundproof chamber is installed by using the pressure welding mechanism in which the distance between the fixing member and the vibration-proof member changes as the shaft rotates, and a tool is inserted into a through hole formed in advance in the soundproof panel from the inside of the soundproof chamber. By inserting and rotating the shaft body, the vibration isolation member can be pressed against the sound insulation panel or structure to fix the sound insulation chamber to the structure by increasing the distance between the fixing member and the vibration isolation member. it can. Therefore, the method of installing the soundproof room does not require a work space outside the soundproof room, so that the soundproof room can be fixed to the structure with a relatively small gap.

It is preferable that the fixing member is fixed inside the through hole of the sound insulation panel.

The fixing member may be fixed to the structure.

It is advisable to assemble the soundproof room at the installation site and perform this assembly work from the inside of the soundproof room. In this way, by assembling the soundproof chamber at the installation location and performing this assembly work from the inside of the soundproof chamber, the gap between the structure and the soundproof chamber can be made smaller.

Another invention made to solve the above problems is a sound insulation panel used as a wall, floor or ceiling of a prefabricated soundproof room, which is a plate-shaped panel body having through holes communicating with the front and back, and the penetration. It has a fixing member fixed inside the hole and having a screw hole penetrating in the normal direction of the panel body, and an engaging structure that engages with the screw hole and engages a tool at one end, and the other end The sound insulation panel is provided with a shaft body protruding to the outside of the through hole and a vibration isolator member supported at the other end of the shaft body.

The sound insulation panel includes the fixing member, the shaft body having the engaging structure, and the vibration isolation member, whereby a tool is inserted into the through hole from the inside of the sound insulation chamber to rotate the shaft body. Therefore, the distance between the fixing member and the anti-vibration member can be widened. As a result, the soundproof panel can be fixed to the structure by pressing the vibration-proof member against the soundproof panel or the structure by performing the work inside the soundproof chamber. As described above, since the soundproof room using the sound insulation panel does not require an outdoor work space when fixed at the installation location, it can be fixed to the structure with a relatively small gap.

Yet another invention made to solve the above problems is a prefabricated soundproof chamber provided with the sound insulation panel.

As described above, in the method of installing the soundproof room, the soundproof panel, and the assembly type soundproof room of the present invention, the soundproof room can be fixed to the structure with a relatively small gap.

It is a schematic plan view which shows the installation state of the assembly type soundproof room provided with the sound insulation panel of FIG. It is a schematic elevation view of the installation state of the assembly type soundproof room of FIG. It is a flowchart which shows the procedure of the installation method of the assembly type soundproof room of FIG. It is a schematic cross-sectional view which shows the pressure welding mechanism used in the installation method of the soundproof chamber which concerns on another embodiment of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[First Embodiment]
[Sound insulation panel]
The sound insulation panel 1 according to the embodiment of the present invention shown in FIG. 1 is used as a wall, floor or ceiling of an assembly-type soundproof room.

The sound insulation panel 1 includes a plate-shaped panel main body 2 and a pressure welding mechanism 3 arranged on the panel main body 2.

<Panel body>
The panel body 2 includes one or a plurality of through holes 4 formed so as to communicate with each other on the front and back surfaces. Further, the panel main body 2 is preferably formed in a rectangular shape in the normal direction, and the through hole 4 is preferably formed in the vicinity of the outer edge, and more preferably the through hole 4 is formed in the vicinity of the corner portion.

It is desirable that the panel body 2 has not only sound insulation but also nonflammability. In addition, "having non-flammability" means preferably a non-combustible material compliant with the Building Standards Act, and more preferably an international code (FTP code: International Code for Application of) regarding the application of the 2010 fire test method. It means that it is a non-combustible material compliant with Fire Test Procedures).

The lower limit of the average thickness of the panel body 2 is not particularly limited as long as sound insulation can be obtained, but 2 cm is preferable, and 3 cm is more preferable. On the other hand, the upper limit of the average thickness of the panel body 2 is preferably 12 cm, more preferably 8 cm. If the average thickness of the panel body 2 is less than the lower limit, a part of the pressure welding mechanism 3 described later may protrude into the soundproof chamber, or sufficient sound insulation and strength may not be obtained. On the contrary, when the average thickness of the panel main body 2 exceeds the upper limit, the soundproof panel 1 and the soundproof chamber assembled by using the soundproof panel 1 may become unnecessarily heavy.

As a specific example of the structure of the panel body 2, there is an aggregate 5 that is connected in a square frame shape in a cross-sectional view to form a frame, and a pair of sound insulation plates that are arranged so as to sandwich the frame formed by the aggregate 5. 6. The sound absorbing material 7 filled in the space surrounded by the aggregate 5 and the sound insulating plate 6 and the surface plate 8 laminated on the outer surface of the sound insulating plate 6 can be provided. The through hole 4 is preferably formed so as to penetrate the aggregate 5.

(aggregate)
As the aggregate 5, for example, a square pipe, a lip groove shaped material (C-shaped channel), or the like can be used. Further, as the material of such an aggregate 5, for example, steel, stainless steel, aluminum and the like can be mentioned.

(Sound insulation board)
As the sound insulation board 6, for example, gypsum board, calcium silicate board, plywood, MDF (medium density fiberboard: medium density fiberboard), particle board and the like can be used.

(Sound absorbing material)
As the sound absorbing material 7, for example, glass wool, rock wool, ceramic wool or the like can be used.

(Surface plate)
As the surface plate 8, for example, a plated steel plate, a non-combustible coated steel plate, a stainless steel plate, or the like can be used.

(Through hole)
The through hole 4 may penetrate the panel main body 2 in the thickness direction, and the cross-sectional shape and the hole diameter may not be constant. As an example, when penetrating a hollow aggregate 5, the lumen of the aggregate 5 is interpreted as part of the through hole 4. The through hole 4 has a size that enables the operation of the pressure welding mechanism 3 described later by inserting the tool T at least on the indoor side of the panel main body 2.

Further, the through hole 4 may be sealed by a pressure contact mechanism 3 described later, at least on the outer surface side of the panel main body 2. By sealing the through hole 4 with the pressure welding mechanism 3, sound insulation and fire resistance can be ensured relatively easily.

<Pressure welding mechanism>
The pressure welding mechanism 3 penetrates the fixing member 9 fixed inside the through hole 4 of the panel body 2 and the fixing member 9, one end is arranged inside the through hole 4, and the other end is outside the through hole 4. That is, the shaft body 10 arranged on the outer surface side of the panel main body 2 and the vibration isolator member 11 supported by the other end of the shaft body 10 are provided. Further, it is preferable that the pressure welding mechanism 3 further includes a lock member 12 for fixing the shaft body 10 to the fixing member 9.

(Fixing member)
The fixing member 9 has a screw hole 13 penetrating so as to extend in the normal direction of the panel body 2. As the fixing member 9, for example, a nut, a metal plate having a screw hole 13 formed therein, or the like can be used.

The fixing member 9 is preferably fixed to the outdoor side inside the through hole 4, typically to the outdoor inner surface of the hollow aggregate 5, as shown. The method of fixing the fixing member 9 is not particularly limited, but for example, welding to the aggregate 5 or screwing may be used.

(Axis body)
The shaft body 10 has an external screw 14 screwed into a screw hole 13 on the outer periphery thereof, and has an engaging structure 15 in which a tool T engages with an end portion on a side arranged inside the through hole 4.

As the engaging structure 15, for example, a cross hole, a ground hole, a hexagonal hole, a hexarobula hole, a square head, a hexagonal head, or the like can be applied.

The lower limit of the axially movable distance of the shaft body 10 with respect to the fixing member 9 is preferably 1 cm, more preferably 2 cm. On the other hand, as the upper limit of the movable distance in the axial direction with respect to the fixing member 9 of the shaft body 10, 10 cm is preferable, and 7 cm is more preferable. If the movable distance of the shaft body 10 with respect to the fixing member 9 in the axial direction is less than the above lower limit, or if there is a deviation in the installation position of the soundproof chamber or an error in the arrangement position of the structure S, the vibration isolation member 11 is attached to the structure S. It may not be possible to press on. On the contrary, when the movable distance of the shaft body 10 with respect to the fixing member 9 in the axial direction exceeds the above upper limit, the shaft body 10 may become long and protrude inside the soundproof chamber.

(Vibration isolation member)
The vibration isolator member 11 secures a pressure contact force with respect to the structure S to maintain a fixed state of the soundproof chamber, and absorbs the vibration so that the vibration does not propagate between the soundproof chamber and the structure S. It has an elastic body 16 that can be compressed in the axial direction of the body 10.

The anti-vibration member 11 is rotatably supported by the outdoor end of the shaft body 10 or has a structure in order to prevent the surface of the structure S from being damaged by rotating integrally with the shaft body 10. It is preferable that a part including a part that is pressed against the object S is rotatably configured with respect to the other part.

As the elastic body 16, for example, a metal spring such as a coil spring, a nonflammable rubber, or the like can be used.

(Lock member)
The lock member 12 prevents the shaft body 10 from unintentionally rotating and keeps the soundproof chamber fixed.

As the lock member 12, for example, a lock nut that is screwed into the shaft body 10 and pressed against the fixing member 9 can be used. When a locknut is used as the lock member 12, the rotation of the shaft body 10 can be prevented by inserting a tool such as a long socket wrench into the through hole 4 and tightening the lock member 12.

[Assembled soundproof room]
2 and 3 show the installation state of the assembled soundproof room according to another embodiment of the present invention. Note that FIGS. 2 and 3 show an example in which a soundproof chamber is fixed in the cabin of a ship so as to be close to the outer wall W in order to be used as a living room for sailors of the ship.

<Structure>
The structure S for fixing the assembly-type soundproof chamber is not particularly limited as long as it is firmly arranged at the installation location, but is, for example, directly or indirectly rigidly attached to the building frame or the structure of the transport aircraft. It can be a column, beam, frame, etc. connected to. Further, as the structure S, for example, a floor, a ceiling, a beam, a pillar, a wall, or the like of a building or a transport aircraft may be used.

As the material used as such a structure S, for example, steel materials such as T-shaped steel and L-shaped steel can be preferably used. In the illustrated example, the structure S is arranged upright between the floor F and the ceiling C of the cabin in the vicinity of the outer wall W having the window G, and between the T-shaped steels. It is an L-shaped steel to be hung.

The assembly-type soundproof chamber includes the sound insulation panel 1 of FIG. 1 as a component forming at least a portion of the wall and ceiling fixed to the structure S. Further, the assembled soundproof room is provided with a flooring material having sound insulation and has a soundproof door D. The assembled soundproof room may further have a window H provided opposite to a window G provided on the outer wall W of the ship.

As shown in FIG. 1, the assembly-type soundproof chamber pushes the vibration-proof member 11 supported by the tip of the shaft of the sound-insulating panel 1 against the structure S at the installation location by projecting the shaft body of the sound-insulating panel 1 to the outside. It is fixed by that.

In the assembly type soundproof room, the sound insulation panel 1 is assembled so that the pressure welding mechanism 3 is arranged near the corner formed by the wall and the wall of the soundproof room or near the corner formed by the wall and the ceiling or the floor. It is more preferable that the pressure welding mechanism 3 is assembled so as to be arranged in the vicinity of the corner formed by the two walls arranged perpendicular to each other in the soundproof chamber and the ceiling or floor.

Further, it is preferable that the assembly type soundproof chamber is assembled so that the pressure contact mechanism 3 is arranged at the opposite positions of the sound insulation panels 1 facing each other. By arranging the pressure contact mechanism 3 at the facing position in this way, the assembly type soundproof chamber can be more reliably sandwiched and fixed between the two structures S.

Further, a plurality of the assembled soundproof chambers may be fixed between the pair of structures S. In this case, one pressure welding mechanism 3 of the adjacent assembly type soundproof chamber may press the vibration isolator member 11 against the outer surface of the other sound insulation panel 1 of the adjacent assembly type soundproof chamber.

<Advantage>
By using the sound insulation panel 1 as a wall, floor, or ceiling of the soundproof room, a tool T is inserted into the through hole 4 from the inside of the soundproof room after assembly to operate the pressure welding mechanism 3, and the structure at the installation location can be used. On the other hand, the soundproof chamber can be fixed by pressure-welding the vibration-proof member 11. Therefore, since the soundproof chamber can be fixed by operating the pressure welding mechanism 3 from the indoor side, it is not necessary to secure a work space between the structure and the soundproof chamber, and the soundproof chamber has a relatively small gap with respect to the structure. Can be fixed with.

Further, in the sound insulation panel 1, since the pressure contact mechanism 3 presses the vibration isolation member 11 against the structure to fix the sound insulation chamber, the vibration of the structure is absorbed by the vibration isolation member 11, for example, the power engine of the transport aircraft. It is possible to prevent the vibration of the installation location from being conducted into the soundproof room, such as the vibration of the soundproof room.

[How to install a soundproof room]
As shown in FIG. 4, the assembly-type soundproof chamber includes a step of assembling the soundproof chamber <step 101: assembly step> and a step of fixing the soundproof chamber to the structure S at the installation location by the pressure welding mechanism 3 <step 102. : It can be installed by a method including a fixing process>.

<Assembly process>
In the assembly process of step 101, the soundproof chamber is provided by using the sound insulation panel 1 in which the shaft body 10 is screwed into the fixing member 9 so that the distance between the vibration isolation member 11 of the pressure welding mechanism 3 and the panel body 2 is relatively small. assemble. In this assembly process, the soundproof room may be assembled at a place different from the installation place, but it is preferable to assemble the soundproof room at the installation place.

When assembling the soundproof room at the installation location, it is advisable to perform the assembly work from the inside of the soundproof room. By assembling the soundproof chamber from the inside at the installation location, the gap between the soundproof chamber and the structure S can be made smaller.

As a specific example of the assembly process, first, a member to be the floor of the soundproof room is arranged at an installation location close to the structure S, and a member such as a sound insulation panel 1 is attached to the peripheral edge of the floor on the floor to form a wall. Do the work to configure. Further, the soundproof room is assembled by attaching a member such as a sound insulation panel 1 to the upper edge of the wall and performing the work of constructing the ceiling from the lower side of the ceiling. In this assembly process, the vibration isolator member 11 of the pressure welding mechanism 3 is kept close to the panel body 2.

<Fixing process>
In the fixing step of step 102, the anti-vibration member 11 is separated from the panel main body 2 by inserting the tool T into the through hole 4 of the sound-insulating panel 1 and rotating the shaft body 10 from the inside of the sound-insulating chamber. The member 11 is pressed against the structure S. In this way, by pressing the plurality of pressure welding mechanisms 3 of the soundproof chamber to the surrounding structure S, the soundproof chamber can be fixed so as not to be movable up, down, left and right.

After the fixing step, the opening of the through hole 4 on the soundproof chamber side may be sealed with another member such as a skirting board.

[advantage]
Since the soundproofing panel 1 is used in the installation method of the soundproofing room, the pressure welding mechanism 3 is operated from the inside of the soundproofing room after assembly to fix the soundproofing room to the structure S, so that the structure and the soundproofing room are installed. It is not necessary to secure a work space between the two, and the soundproof chamber can be fixed to the structure S with a relatively small gap.

[Second Embodiment]

In FIG. 5, the same components as those in FIG. 1 are designated by the same reference numerals, and duplicate description will be omitted.

[Pressure welding mechanism]
The pressure contact mechanism 3a includes a fixing member 9a fixed to the structure S, a shaft body 10a whose one end engages with the fixing member 9a, and a vibration isolator member 11a supported by the shaft body 10a. Further, it is preferable that the pressure contact mechanism 3a further includes a lock member 12a for fixing the shaft body 10a.

As the fixing member 9a, for example, a long nut, a block having a screw hole 13a formed, a member in which a long nut is arranged in a plate state fixed to the structure S, or the like can be used. Further, when the structure S is provided with a hole for inserting the shaft body 10a, a plate-shaped body having a screw hole 13a formed may be used as the fixing member 9a.

The method of fixing the fixing member 9a to the structure S is not particularly limited, and for example, adhesion with an adhesive, welding, screwing, or the like can be used. Since the fixing member 9a is finally pressed by the structure S, the fixing member 9a is fixed to the structure S to the extent that the fixing member 9a does not rotate together with the shaft body 10a when the shaft body 10a is rotated. It suffices if the fixing member 9a can be held.

(Axis body)
The shaft body 10a has an external screw 14a screwed into a screw hole 13a on the outer periphery thereof, and has an engaging structure 15a in which the tool T engages with an end portion on the side protruding from the fixing member 9a.

As the engaging structure 15a, for example, a cross hole, a ground hole, a hexagonal hole, a hexarobula hole, a square head, a hexagonal head, or the like can be applied.

(Vibration isolation member)
The vibration isolator member 11a secures a pressure contact force with respect to the sound insulation panel 1a to maintain a fixed state of the soundproof chamber, and also absorbs vibration so that vibration does not propagate between the soundproof chamber and the structure S. It has an elastic body 16a that can be compressed in the axial direction of the body 10a.

The vibration isolator member 11a is rotatably supported by the shaft body 10a or pressed against the sound insulation panel 1a in order to prevent the surface of the sound insulation panel 1a from being damaged by rotating integrally with the shaft body 10a. It is preferred that the portion including the portion is rotatably configured with respect to the other portion.

As the elastic body 16a, for example, a metal spring such as a coil spring, rubber, or the like can be used.

In the method of installing the soundproof room, a through hole 4a for operating the pressure welding mechanism 3a from the inside of the soundproof room is formed in advance in the panel main body 2a of the soundproof panel 1a of the soundproof room. Then, after arranging the soundproof chamber at the arrangement location, the tool T is inserted into the through hole 4a to engage with the engaging structure 15 of the shaft body 10a, and the shaft body 10a is rotated to cause the vibration isolation member 11a. It is moved to the soundproof room side and pressed against the outer surface of the sound insulation panel 1a.

(Lock member)
The lock member 12a prevents the shaft body 10a from unintentionally rotating and keeps the soundproof chamber fixed.

As the lock member 12a, for example, a lock nut or the like that is screwed into the shaft body 10a and sandwiches a part of the sound insulation panel 1a with the vibration isolator member 11a can be used. When a lock nut is used as the lock member 12a, the rotation of the shaft body 10a can be prevented by inserting a tool T such as a long socket wrench into the through hole 4a and tightening the lock member 12a.

<Advantage>
