Description

The present invention relates to a low-noise construction method (low-noise construction for building interior construction) that can suppress noise generated during installation work of a partition device and other construction interior construction.

  Recent buildings are constructed with one floor open, and various partitioning devices are installed to partition the space inside the floor of this large building into a predetermined size. In other words, the partition device can be separated from the building body and installed later, and the size of the room can be freely set and changed.Therefore, each room (office space) may be partitioned by the partition device. Many.

  In addition, a low partition composed of low-profile panels is often used in order to form individual small spaces within a relatively large office space partitioned by a partition device. In addition to the partitioning device, the space may be partitioned by a wall composed of a gypsum board and a lightweight steel frame.

  By the way, when installing the partition device, members such as partition panels, studs, floor rails and ceiling rails are generally used. The floor rails are fixed to the floor surface, the ceiling rails are fixed to the ceiling surface, and the partition panels are floors. Installed between rail and ceiling rail.

  FIG. 9 shows a general partitioning device, but adjusters (b), (b),... Are arranged in places on the floor rail (a), and the adjusters (b), (b),. A partition panel (d) is placed on a baseboard (c) that is placed and supported at a predetermined height. The upper ends of the partition panels (d) are positioned by being fitted to the ceiling rail (e), and studs (f) are interposed between the partition panels (d), (d),. .

  The office space is partitioned by the partition device configured as described above, but the size (width) of the office may be changed later.In such a case, the existing partition device is removed and a new partition is created. It is possible to create another office space by installing the device. In other words, the partition device can change the office space freely without modifying the building body.

  By the way, when the existing partition device is removed and a new partition device is installed, the partition panel, floor rail, ceiling rail, stud, etc. are cut into predetermined dimensions according to the specifications of the office space, and these members are It must be screwed in place. Individual members are manufactured at the factory, but the partition installation work is a field work, and the noise generated at this time is very large.

  Conventionally, the idea that noise is attached to the installation work of the partitioning device and cannot be dealt with is a reality. Therefore, conventionally, in order to avoid inconvenience on the same floor and upper and lower floors of a building, the partition device is installed mainly in a holiday work or night work in an office space. Therefore, the labor contractor is forced to be harsh, and the construction period is prolonged because the construction is performed using such a time zone. Of course, the interior work is not only a partition device, but also general interior work such as building walls, ceilings, floors, etc. is often performed, and in this case, the same amount of noise is involved.

  As described above, the interior work for constructing the walls, ceiling, and floor of the building, such as the installation work for the partition device, is often a holiday work or a night work, and thus has the above-described problems. The problems to be solved by the present invention are these problems, and the low-pitched sound construction of the building interior work that enables daytime work on weekdays by suppressing noise so as not to bother the same floor and upper and lower floors of the building Providing services (small-scale construction for architectural interior work).

  When installing a partition device or constructing a building wall, ceiling, floor, etc., noise of up to about 100 dB is generated. This 100 dB is comparable in size to the noise under the guard when a train passes, and conventionally, holiday construction and night construction are performed so as not to bother the same floor and upper and lower floors of the building. Therefore, in the present invention, on-site processing of each member such as a lightweight steel frame as a base of a wall or ceiling of a building or a floor rail or a ceiling rail constituting a partition device is performed in a soundproof partition booth. And the tool used when attaching each processed member uses a small sound tool.

  The sound construction service (sound construction) using this soundproof partition booth is not possible due to the noise generated during the construction, and the interior construction work such as the installation of the partition device during the daytime on weekdays is not possible. When construction work and night work are requested from the customer side, the sales department proposes to the customer. Therefore, the members constituting the soundproof partition booth are brought into the site together with the members constituting the building walls, ceiling, floor, etc., and the members constituting the partition device, and the soundproof partition booth is assembled at an appropriate place. Then, operations such as cutting and drilling of each member are performed in the soundproof partition booth, and the processed members are unloaded from the soundproof partition booth and assembled.

  When the construction of the walls, ceiling, floor, etc. of the building is completed and the installation of the predetermined partition device is completed, the soundproof partition booth becomes unnecessary and is dismantled and transported to the next construction site. Here, the soundproof partition booth is an assembly of a plurality of partition panels and has an entrance door. The partition panel has a sound absorbing function, and a part of the noise hitting the partition panel is reflected, but most of it is absorbed.

  Therefore, the basic structure as a partition panel is configured by sticking a surface material on both sides of the filler, but a plurality of small holes penetrate through almost the entire inner surface material, and the filler is partitioned into a plurality of spaces. In addition, a plurality of honeycomb cores having a certain thickness are stacked. Then, a thin sheet having a plurality of small holes is interposed between the honeycomb cores, and a panel having a whole sound insulation region without providing holes on one outer surface material is used.

  The low-pitched sound construction service for architectural interior work according to the present invention (low-noise construction for architectural interior work) can assemble a soundproof partition booth on site and process each member in the soundproof partition booth. The cutting processing of the metal that generates the largest noise reaches about 100 dB, but it is reduced to about 60 dB or less outside the soundproof partition booth. The noise of 60 dB or less is the same level as that of a normal office, and the noise is not worrisome at all. On the other hand, by processing each member in the soundproof partition booth, not only the noise is suppressed, but dust and dust generated by the processing can be prevented from scattering in the building.

  The partition panel that constitutes the above soundproof partition booth has a plurality of small holes in the surface material, so when noise occurs during work inside the booth, the noise passes through the panel holes and enters the interior. And is absorbed by the internal filler. That is, the filler inside the panel is constituted by a honeycomb core, and noise enters the space partitioned by the honeycomb core and attenuates. A honeycomb core as a filler is composed of a plurality of layers, and a thin sheet having fine holes is interposed between the honeycomb cores.

  Therefore, a part of the noise that has entered from the small hole in the surface material is absorbed in the partition space of the honeycomb core, while the other part is separated from the adjacent honeycomb core through the hole in the sheet. Enter. And it is absorbed in this partition space. Furthermore, a part of the noise that has not been absorbed passes through the hole in the sheet and enters the partition space of the honeycomb core laminated on the rear side. However, since the hole is not penetrating through the opposite surface material (the surface material outside the booth), the sound leaking to the outside is reduced.

  And when assembling each member processed into the predetermined shape and dimension, the noise which generate | occur | produces is suppressed by using a small sound tool. In this way, the installation work of the partition device and other architectural interior work do not generate a great deal of noise, so there is no need to perform holiday work or night work as in the past, and work can be done in the daytime on weekdays. Become. As a result, the work environment is easy for workers and the construction period is shortened. On the other hand, the soundproof partition booth is constructed by assembling panels, and can be easily disassembled when construction is completed, or can be reused by being transported to another site and assembled. Furthermore, since it is a structure which connects a partition panel via a pole, the magnitude | size (width) can be freely adjusted by the field.

There may be no problem even if a loud noise is generated during installation work of the partition device or other construction interior work, and it may not always be necessary to perform cutting work or the like in the soundproof partition booth. Hereinafter, the sound construction service procedure for building interior construction in the present invention will be described in detail.
(1) Proposal of a low noise construction service (low noise construction) for building interior work to customers.

(2) Determining the date of installation work Once the arrangement of the sound construction service (sound construction) is made, the construction date is determined. Of course, it is weekday daytime.
(3) Set-up sales department to provide a low-noise construction service (low-tone construction) to the construction arrangement department, installment of partitioning equipment and other building interior work to be done by a low-noise construction service (low sound construction) Instructed, the construction arrangement department will set up the sound construction service (sound construction) and give instructions to the contractor.
(4) Deliver soundproof partition booth components to building sites such as building walls, ceilings, floors, or partition device components such as partition panels, studs, floor rails, ceiling rails, baseboards, etc. Carry in and at the same time, carry in the necessary parts to configure the soundproof partition booth.
(5) Assembling the soundproof partition booth The soundproof partition booth is installed at an appropriate location. The structure of the soundproof partition booth will be described later. Since the soundproof partition booth has a structure in which a plurality of partition panels are connected, the size (width) of the booth can be freely changed.
(6) Processing of members Processing such as cutting and drilling of each member is performed in the soundproof partition booth. And each member processed into the predetermined dimension is assembled using a small sound tool.
(7) Completion of partitioning equipment installation work and other architectural interior work
(8) Demolition of the soundproof partition booth After completion of construction work such as installation of the partitioning device for the soundproof partition booth, the soundproof partition booth is dismantled and transported to the end. It is reused at the next construction site.

  FIG. 1 is a specific example of the present invention showing the appearance of a soundproof partition booth for processing each member for building interior such as a partition device. Here, the architectural interior is a concept including a partition device, and mainly targets the wall, ceiling, and floor of the building, but does not limit the form and structure thereof. In the case of a partition device, a low partition, a toilet booth, and a moving partition are also targeted as a broad partition device.

  By the way, the soundproof partition booth of the present invention has a structure in which a plurality of partition sound absorbing panels 1, 1... Are assembled, and an entrance door 2 is attached at least at one place on the side wall. . The ceiling also has a structure in which partition sound absorbing panels 1, 1,. Moreover, the window 3 is provided in the side wall part, and it can take in the light from the outside. And the window 3 can also be provided in the door 2 as needed.

  In the present invention, in this soundproof partition booth, lightweight steel frames, which serve as foundations for building walls and ceilings, floor rails and ceiling rails of partition devices, and other members are cut to a predetermined length. In this soundproof partition booth, the partition sound absorbing panels 1, 1,... Have a function capable of absorbing the noise generated inside so that the noise hardly leaks outside. The noise generated when the member is cut is about 100 dB, but the sound that is absorbed by the partition sound absorbing panels 1, 1. Of course, not only the leakage of noise but also dust and dust are not scattered outside the soundproof partition box.

  FIG. 2 shows a part of the transverse section of the soundproof partition booth, and FIG. 3 shows a part of the longitudinal section. Between the partition sound absorbing panels 1, 1,..., Poles 4, 4,. Here, the connection structure of the partition sound absorbing panels 1, 1... Is not limited to the case shown in FIG. The partition sound-absorbing panel 1 has honeycomb cores 6a, 6b and 6c stacked as fillers between the inner surface material 5a and the outer surface material 5b, and thin sheets 7a and 7b between the honeycomb cores 6a, 6b and 6c. It consists of a structure sandwiched between. A large number of small holes are provided through the inner surface material 5a. The sheets 7a and 7b are also provided with a large number of small holes.

  As shown in the longitudinal sectional view of FIG. 3, the partition sound absorbing panel 1 is supported at an appropriate height by an adjuster 8, and baseboards 9, 9 are magnets 10, 10. The seal 11a is provided along the upper end of the baseboard 9 so as to be in close contact with the panel surface 12 so that there is no gap. Similarly, a seal 11b is provided along the lower end, is in close contact with the floor surface 13, and closes the gap 14. FIG. 4 is a longitudinal sectional view of a portion where the door 2 is attached, and an airtight material 15 is attached around the entrance so that no gap is generated when the door 2 is closed.

  By the way, the partition sound absorption panel 1 which comprises the side wall part and ceiling part of the soundproof partition booth where the small sound construction based on this invention is performed is equipped with the function which absorbs the noise which generate | occur | produces in the case of an internal operation | work. FIG. 5 is a specific example showing a cross section of the partition sound absorbing panel 1. In the figure, 5a is an inner surface material, 5b is an outer surface material, and three honeycomb cores 6a, 6b, 6c are laminated between the inner and outer surface materials 5a, 5b. A thin sheet 7a is interposed between the honeycomb cores 6a and 6b, and a thin sheet 7b is also interposed between the honeycomb cores 6b and 6c. Here, as the thin sheets 7a and 7b, for example, an aluminum foil or a resin film is used.

  The honeycomb cores 6a, 6b, and 6c are structures of a certain thickness made of paper, metal, or resin, and a plurality of small partitioned spaces 16a, 16a, ..., 16b, 16b, ..., 16c. 16c... And this space 16a is only divided by the adjacent space 16a and the side wall 17a, and the both surface side has formed the through-hole opened. Accordingly, the sheet 7a is interposed between the honeycomb cores 6a and 6b to close the through hole, but the sheet 7a is provided with small holes 18, 18,. In the present invention, the honeycomb core 6 as a filler can be interpreted in a broad sense, and can be used as a filler as long as the space 16 partitioned by the side wall 17 is formed. The shape of the space 16 is not particularly limited.

  By the way, when noise is generated in the soundproof booth partitioned by the partition sound absorbing panels 1, 1,..., The sound wave diffuses to the surroundings, and a part thereof hits the partition sound absorbing panels 1, 1,. Then, as shown in the figure, the sound wave hitting the partition sound-absorbing panel 1 passes through the small hole 19 formed in the inner surface material 5a and enters the space 16a of the honeycomb core 6a. This space 16a only has a small hole 19 in the inner surface material 5a and a small hole 18 provided in the sheet 7a, and the sound wave that has entered the space 16a vibrates the side wall 17a of the honeycomb core 6a and consumes energy, Decay immediately.

  However, a part of the sound wave that is not attenuated passes through the small hole 18 provided in the sheet 7a and enters the space 16b of the adjacent honeycomb core 6b stacked. Then, as in the case of the space 16a, the side wall 17b of the space 16b is vibrated and attenuated. Furthermore, the sound waves that are not attenuated enter the space 16c of the honeycomb core 6c. Since the honeycomb core 6c is closed by the outer surface material 5b, the sound leaking out of the soundproof box is reduced.

  As described above, the soundproof booth of the present invention is constituted by the partition sound absorbing panels 1, 1,..., And the sound waves hitting the partition sound absorbing panel 1 pass through the holes 19, 19,. It is possible to enter the partition spaces 16a, 16b and 16c and attenuate. And since the outer surface material 5b stuck on the outer side is a sound insulation region in which the holes 19, 19,... Are not provided, the sound leaking outside the soundproof booth is reduced.

  Thus, in this invention, the soundproof partition booth which can be assembled easily is installed in the field, and each member of a partition apparatus and the member for building interiors are processed in this soundproof partition booth. For example, partition panels, floor rails, ceiling rails, studs, gypsum boards constituting building walls and ceilings, and lightweight steel frames as base materials for mounting gypsum boards must be cut to predetermined dimensions. In addition, it is necessary to process holes, screw holes, and grooves in necessary places.

  Here, the processing that generates the largest noise is the cutting processing, and the size is about 100 dB. This is comparable to the noise under the guard when a train passes. If this noise spreads to the surroundings, it will cause trouble on the same floor and upper and lower floors of the building.

However, if the soundproof partition booth is installed inside the building and processed in the building, the noise that leaks outside through the soundproof partition booth is reduced to about 60 dB. 6 and 7 show the magnitude of noise in that case.
FIG. 6 shows noise when a baseboard is cut with a high-speed cutter in the same room.
A: The noise at a position 3 m from the cutting machine is 98 dB without a soundproof partition booth.
B: When a soundproof partition booth is used, the noise at a position 3 m from the cutting machine is reduced to 64 dB.
C: When a soundproof partition booth is used, the noise at a position 10 m from the cutting machine is 60 dB.

FIG. 7 shows the noise in the adjacent room 5 m away from the cutter when the baseboard is cut with a high-speed cutter.
A: 82 dB in the state without the soundproof partition booth.
B: When a soundproof partition booth is used, it is reduced to 58 dB.
If a soundproof partition booth is used, it is generally in the state shown in FIG. 7B. If the noise in the adjacent office is about 58 dB, the noise is not worrisome.

For reference, the noise in various places is as follows.
(1) 40 dB Quiet residential area, library (2) 50 dB Quiet park, quiet office (3) 60 dB Quiet passenger car interior, normal conversation (4) 70 dB Vacuum cleaner sound, train car interior (5) 80dB Road with heavy traffic, subway car (6) 90dB factory, loud voice, dog cry (5m in front)
(7) 100dB Under guard when the train passes (8) 110dB Car horn (2m ahead)
FIG. 8 is a specific example showing a floor structure on which soundproof partition booths are installed. The soundproof partition booth uses sound absorbing panels 1, 1... At the side wall and the ceiling, so that the noise generated inside is absorbed and the sound leaking outside is reduced. However, this noise may leak outside along the floor. Therefore, a soundproof partition booth may be installed in a state where a curing sheet 20 is laid on the floor surface 13 and a soundproof panel 21 (for example, a wooden porous panel) is laid thereon. The curing sheet 20 is laid on the soundproof panel 21. Here, the curing sheet 20 and the soundproof panel 21 are commercially available products.

  By the way, in the soundproof partition booth, the sound absorbing panels 1, 1... Are generally used for the side wall and the ceiling, and all the panels are used as the sound absorbing panels 1, but some panels are used as necessary. A general partition panel may be used. And the window glass which comprises the window 3 provided in the said side wall part uses the thick (about 10 mm) acrylic glass with a soundproofing effect. Furthermore, in order to block the joint formed between the sound absorbing panels 1, 1..., A magnetic tape may be attached along the joint.
