JP6780279B2 - Soundproof room fixture, assembly type soundproof room set and how to install the soundproof room - Google Patents

Description

The present invention relates to a soundproof room fixture, an assembly type soundproof room set, and a method for installing the soundproof room.

Soundproof rooms formed by connecting sound insulation 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 machine 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. For this reason, installing a soundproof room inside the ship is considered to be a realistic solution.

When a soundproof room is installed in a transport machine 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 machine. 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 transport aircraft, it is required to improve the space utilization efficiency, so it is desirable to install the soundproof room with the space between the wall and the pillar as small as possible and the gap between the adjacent soundproof rooms. 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 inconveniences, it is an object of the present invention to provide a soundproof chamber fixture, an assembly type soundproof chamber set, and a method for installing the soundproof chamber, which can fix the soundproof chamber to the structure with a relatively small gap. And.

The invention made to solve the above problems is a soundproof room fixture that fixes the soundproof room by being arranged between the soundproof room and the structure at the installation location, and the soundproof room and the structure. A base plate fixed to one side, a bolt placed upright on this base plate, a nut engaged with this bolt, and placed on the opposite side of the nut base plate so as to move along the bolt together with this nut. It is a soundproof chamber fixture characterized by being provided with a vibration-proof member.

Since the distance between the base plate and the anti-vibration member can be adjusted by the bolts and nuts, the soundproof chamber fixture is arranged so as to sandwich the soundproof chamber, and the base plate is fixed to one of the soundproof chamber and the structure to provide soundproofing. The soundproof chamber can be fixed with a relatively small gap by pressure-welding the vibration-proof member to the other side of the chamber and the structure.

Another invention made to solve the above problems is an assembling type soundproof room set including the soundproof room fixture and a plurality of sound insulation panels assembled in the soundproof room.

Since the prefabricated soundproof chamber set is provided with the soundproof chamber fixture, the nut of the soundproof chamber fixture is operated when assembling the soundproof chamber to make the soundproof chamber a relatively small gap with respect to the structure. The soundproof room can be fixed relatively easily.

Yet another invention made to solve the above problems is a method of installing a soundproof room in which the soundproof room is fixed to the structure of the installation place, and is between the soundproof room and the structure of the installation place. It is a method of installing a soundproof chamber including a step of arranging the soundproof chamber fixture and a step of rotating a nut of the soundproof chamber fixture to press a vibration-proof member against a structure or a soundproof chamber.

The base plate may be fixed to the structure in the arrangement step.

In the arrangement step, the base plate may be fixed to a sound insulation panel forming a part of the sound insulation chamber.

It is preferable to further include a step of assembling the soundproof chamber at the installation location, and perform the assembly work in this assembly step from the inside of the soundproof chamber.

As described above, the soundproof room fixture, the assembly type soundproof room set, and the method of installing the soundproof room can fix the soundproof room to the structure with a relatively small gap.

It is a schematic cross-sectional view which shows the detail of the soundproof chamber fixture of the embodiment different from FIG. 3 of this invention.

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

[First Embodiment]
The assembly-type soundproof chamber set according to the embodiment of the present invention whose assembly is shown in FIGS. 1 and 2 is assembled into the soundproof chamber fixture 1 and the soundproof chamber 2 which are itself another embodiment of the present invention. A plurality of sound insulation panels 3 are provided. Note that FIGS. 1 and 2 are examples in which the soundproof chamber 2 is fixed in the cabin of the ship so as to be close to the outer wall W in order to be used as a living room for crew members.

<Structure>
The structure S for fixing the soundproof chamber 2 is not particularly limited as long as it is firmly arranged at the installation location of the soundproof chamber 2, but is, for example, directly or indirectly to the frame of the building or the structure of the transport machine. It can be a pillar, beam, frame, etc. that is firmly connected to. Further, as the structure S, for example, a floor, a ceiling, a beam, a pillar, or the like of a building or a transport machine may be used.

As the material used as such a structure S, steel materials such as T-shaped steel and L-shaped steel can be preferably used. In the illustrated example, the structure S is placed 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 that is hung.

[Soundproof room fixture]
As shown in detail in FIG. 3 or 4, the soundproof chamber fixture 1 fixes the soundproof chamber 2 by being arranged between the soundproof chamber 2 and the structure S at the installation location. Typically, the soundproof chamber fixture 1 is disposed between the sound insulation panel 3 forming the outer wall of the soundproof chamber 2 and the structure S, as shown in the figure.

The soundproof chamber fixture 1 includes a base plate 4 fixed to one of the soundproof chamber 2 and the structure S, a bolt 5 arranged upright on the base plate 4, and an adjusting nut 6 engaged with the bolt 5. And the anti-vibration member 7 arranged on the opposite side of the base plate 4 of the adjusting nut 6 so as to move along the bolt 5 together with the adjusting nut 6. Further, it is preferable that the soundproof chamber fixture 1 further includes a fixing nut 8 for fixing the adjusting nut 6.

<Base plate>
The base plate 4 is formed in a plate shape, and a bolt 5 is fixed to one surface side, and the surface opposite to the bolt 5 is the surface of the structure S as shown in FIG. 3 or soundproof as shown in FIG. It is attached to the outer surface of the room 2. Further, it is preferable that the base plate 4 has fixing holes 9 on both sides of the bolt 5 in a plan view (direction view perpendicular to the plate surface).

The material of the base plate 4 may be any material having sufficient strength, but for example, a metal such as iron or stainless steel, which is relatively inexpensive and has excellent workability, is preferably used.

(Fixed hole)
The fixing hole 9 is formed so as to penetrate the base plate 4 and facilitates fixing of the base plate 4 to the soundproof chamber 2 or the structure S. Specifically, when the base plate 4 is fixed to the soundproof chamber 2 or the structure S by spot welding, the base plate 4 is relatively easily fixed to the structure S by spot welding in the fixing holes 9. be able to. Further, the base plate 4 may be fixed to the soundproof chamber 2 or the structure S by bolts or screws using the fixing holes 9.

After the soundproof chamber 2 has been fixed, the soundproof chamber fixture 1 presses the base plate 4 against the soundproof chamber 2 or the structure S to maintain the fixed state of the base plate 4 to the soundproof chamber 2 or the structure S. can do. Therefore, the method of fixing the base plate 4 to the soundproof chamber 2 or the structure S may be any method as long as the base plate 4 is held in the soundproof chamber 2 or the structure S until the fixing work of the soundproof chamber 2 is completed. Instead of a firm fixing method such as the above, a simple method using, for example, an adhesive, a magnet, or the like may be used.

<Bolt>
The bolt 5 is fixed perpendicularly to one surface of the base plate 4. The method of fixing the bolt 5 to the base plate 4 is not particularly limited as long as it can be firmly fixed, but relatively simple and reliable welding is preferably used. Further, as the bolt 5, a stud bolt screwed into a screw hole formed in the base plate 4 may be used.

As the lower limit of the outer diameter (nominal diameter) of the bolt 5, 3 mm is preferable, 4 mm is more preferable, and 5 mm is further preferable. On the other hand, the upper limit of the outer diameter of the bolt 5 is preferably 16 mm, more preferably 14 mm. If the outer diameter of the bolt is less than the lower limit, the strength of the bolt 5 may be insufficient. On the contrary, when the outer diameter of the bolt 5 exceeds the upper limit, the soundproof chamber fixture 1 becomes unnecessarily heavy, and there is a possibility that work such as fixing to the structure S becomes complicated.

Further, as the lower limit of the effective length (length of the screw portion) of the bolt 5, 1 cm is preferable, 2 cm is more preferable, and 3 cm is further preferable. On the other hand, the upper limit of the effective length of the bolt 5 is preferably 15 cm, more preferably 12 cm. When the effective length of the bolt 5 is less than the lower limit, the movable range of the adjusting nut 6 is narrowed, so that the vibration isolator member 7 may be pressed against the structure S at the installation site or the sound insulation panel 3 of the sound insulation chamber 2. It may not be possible. On the contrary, when the effective length of the bolt 5 exceeds the upper limit, the gap between the structure S at the installation location and the soundproof chamber 2 may become unnecessarily large.

<Adjustment nut>
The adjusting nut 6 may be screwed into the bolt 5 and rotated from the outside in the radial direction around the axis of the bolt 5 by using a tool such as a spanner, and is typically a hexagon nut. For example, different shapes such as a square nut may be used.

<Vibration isolation member>
The anti-vibration member 7 moves along the bolt 5 together with the adjusting nut 6, and at least in the used state, the tip portion protrudes from the bolt 5 on the opposite side of the base plate 4 and comes into contact with the soundproof chamber 2 or the structure S.

The vibration isolator member 7 secures a pressure contact force with respect to the soundproof chamber 2 or the structure S to maintain a fixed state, and absorbs the vibration to prevent the vibration from propagating between the soundproof chamber 2 and the structure S. Therefore, it is preferable to have an elastic body 10 that can be compressed in the axial direction of the bolt 5.

As the elastic body 10, for example, a metal spring such as a coil spring as shown in the figure, a nonflammable rubber, or the like can be used.

Further, it is preferable that the vibration isolator member 7 is connected to the adjusting nut 6 so as to prevent the soundproof chamber 2 from being detached before being fixed. In this case, it is preferable that the vibration isolator member 7 is configured so that at least the tip portion in contact with the soundproof chamber 2 or the structure S can move in the axial direction of the bolt 5 without rotating together with the adjusting nut 6.

<Fixing nut>
The fixing nut 8 is screwed into the bolt 5 on the base plate 4 side of the adjusting nut 6. The fixing nut 8 is tightened in a direction of moving further toward the adjusting nut 6 from a state of being in contact with the adjusting nut 6, so that the adjusting nut 6 is pressed against the soundproof chamber 2 or the structure S of the vibration isolator member 7. Fix it.

As the fixing nut 8, the one that can be rotated around the axis of the bolt 5 by using a tool from the outside in the radial direction is used like the adjusting nut 6, and the one that can be operated by using the same tool as the adjusting nut 6 is used. It is preferable to do.

〔Soundproof room〕
The soundproof chamber 2 is formed by assembling a plurality of sound insulation panels 3. Specifically, the soundproof room 2 has a floor, a wall, and a ceiling, each of which is formed by connecting a plurality of sound insulation panels 3. Further, as shown in the figure, the soundproof chamber 2 is provided with a door D on a wall not adjacent to the outer wall W of the ship and another soundproof chamber 2, and a sound insulation panel having a window H at a position adjacent to the window G of the outer wall W. May be provided.

In the soundproof chamber 2, a plurality of the soundproof chamber fixtures 1 are arranged around the soundproof chamber 2, and each vibration-proof member 7 is pressed against each other to prevent movement to each soundproof chamber fixture 1 side. It is fixed so that it cannot be moved.

The soundproof chamber fixture 1 is a portion where the strength of the soundproof chamber 2 is relatively high, specifically, the vicinity of a corner portion where two sound insulation panels 3 or three sound insulation panels 3 are arranged at right angles to each other. It is preferable to be arranged in. Further, it is preferable that the soundproof chamber fixtures 1 are arranged at opposite positions of the sound insulation panels 3 facing each other. By arranging the soundproof chamber fixture 1 at the facing position in this way, the soundproof chamber 2 can be more reliably sandwiched and fixed between the two structures S.

Further, a plurality of soundproof chambers 2 may be fixed between the pair of structures S. In this case, the soundproof chamber fixture 1 is also arranged between the adjacent soundproof chambers 2, and the base plate 4 of the soundproof chamber fixture 1 is fixed to the outer surface of one soundproof chamber 2 and the outer surface of the other soundproof chamber 2. The anti-vibration member 7 may be pressed against the surface.

<Sound insulation panel>
It is desirable that the sound insulation panel 3 has not only sound insulation but also nonflammability. In addition, "having non-flammability" means preferably a non-combustible material compliant with the Building Standards Law, 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 Processes).

The lower limit of the average thickness of the sound insulation panel 3 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 sound insulation panel 3 is preferably 12 cm, more preferably 8 cm. If the average thickness of the sound insulation panel 3 is less than the lower limit, sufficient sound insulation and strength may not be obtained. On the contrary, when the average thickness of the sound insulation panel 3 exceeds the upper limit, the assembled sound insulation chamber set may become unnecessarily heavy.

The lower limit of the average width of the sound insulation panel 3 is preferably 30 cm, more preferably 40 cm. On the other hand, the upper limit of the average width of the sound insulation panel 3 is preferably 70 cm, more preferably 60 cm. If the average width of the sound insulation panel 3 is less than the lower limit, the assembly cost of the sound insulation chamber may be unnecessarily increased, or the sound insulation may be lowered. On the contrary, when the average width of the sound insulation panel 3 exceeds the upper limit, it may not be easy to arrange the soundproof chamber fixture 1 on the side far from the open space of the sound insulation panel 3 and operate the adjustment nut 6. ..

As a specific example of the structure of the sound insulation panel 3, an aggregate 11 that is connected in a rectangular frame shape in a cross-sectional view to form a frame body and a pair of sound insulation plates arranged so as to sandwich the frame body formed by the aggregate 11 A sound absorbing material 13 filled in a space surrounded by an aggregate 11 and a sound insulating plate 12 and a surface plate 14 laminated on the outer surface of the sound insulating plate 12 can be provided.

(aggregate)
As the aggregate 11, for example, a square pipe, a lip groove shape material (C type channel), or the like can be used. Further, as the material of such an aggregate 11, for example, steel, stainless steel, aluminum and the like can be mentioned.

(Sound insulation board)
As the sound insulation plate 12, for example, a gypsum board, a calcium silicate board, a plywood, an MDF (medium density fiber board), a particle board or the like can be used.

(Sound absorbing material)
As the sound absorbing material 13, for example, glass wool, rock wool, ceramic wool or the like can be used.

(Surface plate)
As the surface plate 14, for example, a plated steel plate, a non-combustible coated steel plate, a stainless steel plate, or the like can be used.

[How to install a soundproof room]
As shown in FIG. 5, the soundproof room 2 of the assembly type soundproof room set is attached to the structure S at the installation location by the method of installing the soundproof room according to the embodiment of the present invention using the soundproof room fixture 1. Is fixed.

The method of installing the soundproof room is a step of arranging the soundproof room fixture 1 between the soundproof room 2 and the structure S at the installation location <step 101: placement step> and a step of assembling the soundproof room 2 <step 102. : Assembling step> and a step <step 103: pressure welding step> of rotating the adjusting nut 6 of the soundproof chamber fixture 1 to press the vibration isolator member 7 against the structure S or the soundproof chamber 2.

<Placement process>
In the arrangement step of step 101, a portion that should be between the soundproof chamber 2 and the structure S (a portion that does not actually require the soundproof chamber 2 and the structure S to exist and should be between the soundproof chamber 2 and the structure S). The soundproof chamber fixture 1 is arranged in (may be), and the base plate 4 is fixed to the soundproof chamber 2 or the structure S.

As shown in the figure, when the base plate 4 is fixed to the structure, it is relatively easy to firmly fix the soundproof chamber fixture 1 to the structure S by, for example, welding, and it is applicable to various soundproof chambers. can do.

When the base plate 4 is fixed to the sound insulation panel 3, by attaching the sound insulation chamber fixture 1 to the sound insulation panel 3 in advance, the work at the installation location can be simplified and the fixing work of the sound insulation chamber 2 becomes easier. ..

<Assembly process>
In the assembly step of step 102, the soundproof chamber 2 may be assembled at a place different from the installation place, but it is preferable to assemble the soundproof room 2 at the installation place.

When assembling the soundproof room 2 at the installation location, it is preferable to perform the assembly work from the space inside the soundproof room 2. By assembling the soundproof chamber 2 from the inside at the installation location, the gap between the soundproof chamber 2 and the structure S can be made smaller.

As a specific example of this assembly process, first, a member to be the floor of the soundproof chamber 2 is arranged at an installation location close to the structure S, and a member such as a sound insulation panel 3 is attached to the peripheral edge of the floor on the floor. Work to construct the wall. Further, a soundproof room is assembled by attaching a member such as a sound insulation panel 3 to the upper edge of the wall to construct the ceiling from the lower side of the ceiling.

<Pressure welding process>
In the pressure welding step of step 103, the worker inserts a hand into the gap between the soundproof chamber 2 and the structure S and engages the tool with the adjusting nut 6, so that the vibration-proof member 7 is brought into the structure S or the soundproof chamber 2. Press contact (to the soundproof chamber 2 in the illustrated example).

In the method of installing the soundproof room, the assembly process is performed at the installation location, and at least this pressure welding step is performed every time the sound insulation panel 3 to which the soundproof room fixture 1 is to be pressure-welded is assembled to the portion installed in front of the soundproof room 2. That is, it is preferable to perform this before assembling the sound insulation panel 3 on the side where the open space exists. That is, the assembly step of step 102 and the pressure welding step of step 103 may be repeated with one or a plurality of sound insulation panels 3 attached as a unit. By performing the assembly process and the pressure welding process for each sound insulation panel in this way, the worker can operate the soundproof room fixture 1 by inserting only his / her arm without putting his / her body in a narrow space. The gap between the soundproof chamber 2 and the structure S can be made smaller.

<Advantage>
As described above, the method of fixing the soundproof chamber is such that the soundproof chamber 2 is pressed against the surrounding structure S by using a plurality of the soundproof chamber fixtures 1, and the soundproof chamber is sandwiched vertically and horizontally. It can be easily fixed. Since the soundproof chamber fixture 1 can be operated by inserting a tool from the outside in the radial direction, the soundproof chamber 2 can be fixed if there is a gap into which the arm can be inserted.

Therefore, the soundproof room fixture 1, the assembly type soundproof room set including the soundproof room fixture 1, and the method of fixing the soundproof room using the soundproof room fixture 1 make the soundproof room 2 to the structure S. It can be fixed with a relatively small gap.

Further, since the soundproof chamber fixture 1 connects the soundproof chamber 2 and the structure S via the vibration isolator member 7, the vibration of the structure S is absorbed by the vibration isolator member 7, for example, the power engine of the transport machine. It is possible to prevent the vibration of the installation location (mechanical vibration and noise) such as the vibration of the soundproof chamber 2 from being conducted in the soundproof chamber 2.

The adjusting nut 6a is a long nut screwed into the bolt 5. The adjusting nut 6a is screwed into the bolt 5 at a part thereof, and the end portion on the opposite side of the base plate 4 protrudes from the bolt 5. That is, in the soundproof chamber fixture 1a, the movable range of the vibration-proof member 7a is determined by the length of the adjusting nut 6a.

<Vibration isolation member>
The anti-vibration member 7a is held at the end of the adjusting nut 6a on the side protruding from the bolt 5. Therefore, it is not necessary to avoid cushioning the anti-vibration member 7a with the bolt 5, and the degree of freedom in shape is relatively large. Therefore, as shown in the drawing, the vibration isolator member 7a can be configured such that a rubber elastic body 10a or the like having a relatively small axial length of the bolt 5 is efficiently arranged.

[Other Embodiments]
