ことができる。In order to achieve the above-mentioned object, the present invention provides a plate-like or sheet-like reinforcing member and an integral member of this reinforcing member, and is capable of enclosing a predetermined fluid therein. A hollow body, wherein the hollow body expands as the fluid is injected, and is contractible as the fluid is discharged. The hollow body extends along the surface of the reinforcing material in a state where the fluid is enclosed. It has a structure that it expands. According to such a configuration, the sound insulating material can be configured without providing the frame-shaped core material, so that it is possible to reduce the weight of the sound insulating material as a whole, and moreover, before assembling or after disassembling the soundproof room. Can reduce the volume of the entire sound insulation material by removing the fluid enclosed in the hollow body. Therefore, it is possible to easily carry out the work of transporting the sound insulating material during the assembling work and the disassembling work of the soundproof room. In addition, a plurality of sound insulating materials can be preliminarily connected and integrated, and the work of connecting the sound insulating materials can be reduced, and at the time of the transportation work or the storage, the fluid enclosed in the hollow body is removed. By pulling out, it is possible to reduce the total volume while keeping a plurality of sound insulating materials as one body. Furthermore, the reinforcing material and the hollow body are integrally formed, and since the hollow body expands along the surface of the reinforcing material in a fluid-filled state, the reinforcing material always acts as a protective member for the hollow body, Even if a building material or the like accidentally hits the sound insulation material, the hollow body is less likely to be broken and the durability of the sound insulation material can be improved. In addition, since the air layer formed by the hollow body is formed along the surface of the reinforcing material when the fluid is enclosed in the hollow body, it is lightweight and reinforced with the air layer. Depending on the material, more effective sound insulation performance can be obtained.

逆の手順で行うことができる。First, a required number of materials constituting the soundproof room 10 are prepared at the construction site. At this time, each sound insulation panel 19
Air is evacuated from the hollow body 22, that is, the hollow body 22 is crushed and the reinforcing members 21 and 21 are brought into the construction site in a substantially two-thick plate shape that is close to each other.
Then, as shown in FIG. 2, the frame 17 is formed by framing the frame forming member 16 along the outer shape of the soundproof room 10. Around this, the hollow body 22 is filled with air to expand the hollow body 22 and the sound insulation panel 1
9 is set in an expanded state, and the sound insulation panel 19 in the expanded state is attached to the outside of the frame 17 so that the soundproof room 10
The side wall portion 13 is formed. At this time, each sound insulation panel 19
As shown in FIG. 4, their end portions are connected to each other by a joining means 26 such as a known surface fastener or a double-sided adhesive tape, or an adhesive agent. Note that FIG.
As shown in FIG. 5, for example, the joining means 26 is arranged in a band shape so as to be bridged between the surfaces of the adjacent reinforcing members 21 and 21, and the sound insulation panels 19 and 19 are connected in a hinge shape to form a sound insulation panel. 19 can also be used as a door. Then, after the side wall portion 13 is assembled, the ceiling plate 14 is connected to the side wall portion 13 side, and the soundproof room 10 is completed. Further, when disassembling the soundproof room 10, the procedure can be performed in the reverse order of the above.

果をも得る。Therefore, according to such an embodiment, since the sound insulation panel 19 is of the air injection type, not only can the weight of the entire panel be reduced, but also sound insulation can be achieved when the soundproof room 10 is assembled or disassembled. The effect that the volume of the panel 19 can be reduced and the sound insulation panel 19 can be easily carried is obtained. Further, since the reinforcing member 21 made of a sheet material containing a lead component is attached to the surface portion of the hollow body 22, the sound insulating panel 19 can be easily bent in a state where air is removed, and the sound insulating panel 19 is in a folded state. In addition to being able to be transported and stored in the sound insulation panel, it is possible to suppress deterioration of sound insulation performance due to the coincidence effect.
The sound insulation performance of No. 9 can be improved. Furthermore, the sound insulation panels can be easily connected to each other with a surface fastener, a double-sided adhesive tape, or the like, and when the sound insulation panels 19 are connected to each other, fastening work such as screwing is unnecessary, and the sound insulation chamber 10 is assembled and disassembled. It also has the effect of making the work easier.

ととなる。As shown in FIG. 6, as the sound insulation panel 19, the hollow body 22 is filled with air so that the concave portion 28 or the convex portion 29 can be formed at the abutting portion. The sound insulation panels 19 may be connected to each other in a state where they are engaged with each other. As a result, it is possible to more firmly maintain the connected state of the sound insulation panels 19 against the force in the direction crossing the surfaces of the reinforcing members 21 and 21. In this case, the joining means 26 is arranged so as to straddle the surfaces of the reinforcing members 21 and 21, and the sound leakage from the abutted portion of the sound insulation panel 19 is suppressed.

できる。Further, as shown in FIG. 7, a plurality of sound insulation panels 19 can be connected through a connecting tube 31 to form a plurality of sound insulation panels 19. The connection tube 31 serves as an air flow path between the hollow bodies 22, 22 of the sound insulation panels 19, 19.
By discharging or injecting air from the inlet / outlet 24 provided in one sound insulation panel 19, it is possible to take air in and out of each hollow body 22 of the integrated sound insulation panel 19. With such a configuration, the number of steps for assembling the sound insulation panel 19 can be reduced,
The connecting work can be speeded up and simplified.
Moreover, even when the sound insulation panels 19 that constitute the bent portions of the sound insulation room 10 such as the corners of the sound insulation room 10 are integrated, the sound insulation panels 19 are transported or housed when the sound insulation panels 19 are integrated.
