Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated soundproof and hermetically sealed structure used in an indoor playground, karaoke box, or the like.

[0002]

2. Description of the Related Art Some play equipment emits a high level sound in order to give the player a realistic sensation. When this equipment is installed in a building, this high level sound is generated in the adjacent room or adjacent room. May propagate to buildings and cause noise pollution.

In order to prevent such noise pollution, conventionally, a sound-insulating hermetically sealed structure has been constructed by surrounding a play facility that generates a high level of sound with a large panel and arranging the panel above it. .

[0004]

In the conventional sound-insulating hermetically-sealed structure described above, a solid reinforcing frame structure is used to join a joint between a panel on one wall surface and a panel on a wall surface adjacent thereto at a right angle without a gap. In addition to requiring detailed work, a large panel must be created on site, and if the installation location is changed, the panel cannot be carried out and must be destroyed on site. A large amount of waste was generated, which was also a factor of cost increase.

The inner side of the rectangular side portion 32b and the side wall of the side wall 33 or the side view of the adjacent side wall 33 are integrally fixed to each other by welding or the like.

Although the upper and lower end surfaces of the frame member 31 and the upper and lower end surfaces of the gypsum board 35 are flush with each other, as shown in the left side of FIG. The left side surface of the gypsum board 35 is displaced to the right inside by a fixed distance δ, and as shown in the right side of FIG. 10, the right side surface of the gypsum board 35 is different from the right side surface of the frame member 31. It is offset to the right outside by a certain distance δ, and when the panels 30 are aligned in the width direction and joined to each other, there is no gap between the side surfaces of the panels 30.

A door frame 24 is provided on both left and right sides of one wall of the assembly type sound insulation box 1, and a door 25 is attached to one edge of the door frame 24 so as to be openable and closable.

To assemble the above-described embodiment, the upper portion of the panel 30 is inserted into the groove of the inner intermediate downward channel-shaped panel holding member 13 and the panel 30 is lifted upward, and the inner lower upward channel-shaped panel holding member 9 rises up inside. After the lower part of the panel 30 has crossed over the piece 9a, lower the panel 30 to
The panel 30 is stretched inside the frame structure 4 by inserting the lower portion of the groove 30 into the groove of the channel-shaped panel holding member 9 facing downward and upward.

Next, as shown in FIG. 7, the frame structure 4
The glass wool 23 is attached to the outer surface of the panel 30 stretched over the glass wool, and the glass wool 23 is attached by the same operation as described above.
The upper part of the panel 30 is fitted in the groove of the outer middle downward channel-shaped panel holding member 12 and the lower part of the panel 30 is fitted in the groove of the outer lower downward channel-shaped panel holding member 8.

The above operation is performed by fitting the upper and lower parts of the panel 30 into the grooves of the inner upper and lower channel-shaped panel holding members 17 and the inner middle upward channel-shaped panel holding member 15, and then installing the glass wool 23, Thereafter, the upper and lower parts of the panel 30 are fitted in the grooves of the outer upper and lower downward channel-shaped panel holding members 16 and the outer middle upward channel-shaped panel holding members 14, and the fitting portions of the upper and lower panels 30 are shown in FIG. If the gypsum board piece 27 is adhered as described above, the wall portion of the prefabricated soundproof box 1 can be configured.

After that, the same work as the wall portion is performed on the ceiling portion of the frame structure 4, so that the ceiling portion of the assembled soundproof box 1 can be constructed.

Then, both ends of the panel 30 and the outer downward upper channel-shaped panel holding member 8, the inner lower upward channel-shaped panel holding member 9, the outer middle downward channel-shaped panel holding member 12, and the inner middle downward channel-shaped panel holding member 13 are provided. , Outer middle upward channel-shaped panel holding member 14, inner middle upward channel-shaped panel holding member 1
5, the caulking agent 26 having high adhesiveness is loaded into the fitting portions of the outer upper and lower downward channel-shaped panel holding members 16, the inner upper and lower downward channel-shaped panel holding members 17, and the upper inward channel-shaped panel holding member 18.

After that, if a sound absorbing ceiling plate (not shown) is stretched over the ceiling inside the assembly type sound insulation box 1 in the same manner as in a conventional building, the assembly type sound insulation box 1 can be assembled, and in the reverse order. The assembly-type sound insulation box 1 can be disassembled by performing the above work.

In the embodiment shown in the drawings, the gypsum board 35 is made of a relatively light and thin gypsum board 35, but the gypsum board 35 is a frame member composed of an outer frame 32, a horizontal groove 33 and a vertical groove 34. The gypsum board 35 is firmly attached on both sides of the 31 and the panel 30 is stretched on both sides inside and outside with the pillar 5 sandwiched therebetween so that the gypsum board 35 is 4
Constructed in a layered structure, glass wool 23 between the inner and outer panels 30
And the caulking agent 26 is loaded into both ends of the panel 30 and the fitting portions of the outer downward channeling panel holding member 8 and other channel-shaped panel holding members, and the ceiling of the assembly type sound insulation box 1 is also filled. As it has a double sound insulation structure, its sound insulation is extremely high.

Further, the width L of the panel 30 is narrower than the width L of the channel-like panel holding members 8a, 9a, ... Plus length L
Since the distance X between the horizontal section pieces 8c and 9c of the channel-shaped panel holding members 8 and 9 which are vertically opposed to each other is set to be slightly longer than + W, the upper end of the panel 30 serves as an upper channel-shaped panel holding member. Insert and lift the panel 30 upwards, and the lower end of the panel 30 rides over the narrow rising part of the lower channel-shaped panel holding member and then lowers the panel 30 to hold the upper and lower ends of the panel 30 to the upper and lower channel-shaped panel holding members. Since the panel 30 can be attached to the upper and lower channel-shaped panel holding members without sequentially inserting the members from one end, the tensioning operation of the panel 30 can be performed easily and efficiently in a short time.

Further, since the frame structure 4 is composed of the columns 5, the horizontal brace beams 6 and the wall braces 7, it has sufficient strength and rigidity to support the panel 30.

Furthermore, since the panel 30 is removably stretched over the frame structure 4 and the frame structure 4 can be disassembled, the prefabricated sound insulation box 1 is reused in another place, and waste is generated. The cost can be reduced while being prevented.

Moreover, since the frame structure 4 and the panel 30 are all made of non-combustible material, they are excellent in heat resistance and fire resistance.

In the above-mentioned embodiment, the holding member mounting bracket 11 of the support column 5, the outer middle downward channel-shaped panel holding member 12, the inner middle downward channel-shaped panel holding member 13,
An outer middle upward channel-shaped panel holding member 14, an inner middle upward channel-shaped panel holding member 15, an outer upper downward channel-shaped panel holding member 16, an inner upper downward channel-shaped panel holding member 17, and an upper inward channel-shaped panel holding member 18. Although they are connected by welding or the like, if these are detachably connected by fixing means such as bolts and nuts, wedges, the assembling / disassembling of the assembly type sound insulation box 1 can be further improved.
