Description

[Detailed description of the invention] : Industrial application field] The present invention targets a sensitive device that is a source of %i:tr, such as a press machine installed in a factory building, and is aimed at reducing noise by surrounding the machine. 11 We tried to prevent it from spreading to surrounding areas.
Concerning Tachi-ni's soundproof box.

(Conventional technology) When installing and using a machine that makes a lot of noise, such as a press machine, in a factory building, make sure that other workers working in the same building are not affected by the noise. In addition, the press I1w & 1 is stored in a soundproof box for use.

Here, the structure 1 of the conventional soundproof box,
The machine is installed by welding steel panels to the steel frame assembled on site to cover the surrounding walls and ceiling, and then affixing soundproofing material to the inner surface of the panels. .

[Problems to be Solved by the Invention] By the way, in the soundproof box of the conventional structure described above, the iron plate banuru is large in size and heavy, and it is difficult to assemble it.
A crane, welding machine, etc. to handle the ornaments is required, and it is not possible to assemble the soundproof box easily in places without these equipment, and the construction requires time and effort as the soundproofing material is pasted on the inside of the soundproof box at the construction site. It takes. Moreover, it is difficult to assemble the box in a building with a low ceiling because it requires the use of a crane, and since the soundproof box has a welded structure, it is extremely difficult to disassemble the box once it has been assembled.

The present invention has been made in consideration of the above points, and has excellent soundproofing performance, and can be easily assembled and dismantled manually without the need for a crane or welding machine. The purpose is to provide a soundproof box.

[Means for Solving the Problems] In order to solve the above problems, the soundproof box of the present invention has the following features:
From the assembly of the foundation channel material laid on the floor, the pillars erected on the foundation channel materials, the beam materials connecting the pillars, and the split-structure soundproof panel that covers the area around the box and the ceiling surface. The structure will be constructed by inserting soundproof panels one by one into the framework assembled from the above-mentioned foundation channel materials and one support beam material.

Here, the soundproof panel in the above configuration is a laminated structure in which vibration-proof rubber, sound-absorbing material, and perforated boards are stacked on the inner surface of the outer wall board.

Additionally, in order to keep noise leakage from the soundproof box to a low level, it is recommended to assemble the soundproof panels by interposing elastic padding in the overlapping areas to close the gaps.

[Operation] In the above configuration, the soundproof bubble that covers the periphery of the box and the ceiling insulates, absorbs, and attenuates the noise emitted from the machine installed in the box, thereby reducing the noise level propagating to the surroundings. In addition, the soundproofing panels are made of a laminated structure in which vibration-proof rubber sound-absorbing material and perforated boards are layered on the inner side of the outer wall board made of synthetic resin, and elastic filling is used between the soundproofing panels to close the gaps. intervening, the soundproofing effect is further enhanced.

22. Individual soundproofing panels are lightweight objects that can be easily carried manually by about two workers, such as groove-shaped,
Since the soundproof panels are inserted one by one into Ws-shaped pillars and assembled in a stacked manner, construction can be carried out by hand without using a crane or the like, even in buildings with low ceilings.

〔Example: Embodiments of the present invention will be described below based on the drawings.

Figure 1 is a diagram showing the complete assembly of the soundproof box, with 1 being the foundation channel material, 2 the pillars, 3 the beams, 4 the soundproof panel with a split structure, and 5 the second sliding door.

Such a soundproof box is assembled by the following construction method. As shown in Figure 2, for installation, first lay the foundation channel material 1 on the floor surface of the site, and to install the four corners and the door, vertically erect supports 2 such as channel steel at the locations and tighten bolts. In addition, a channel steel beam 3° reinforcing beam 6. Build a frame by tightening bolts such as the door rail 7.Next, to the above-mentioned frame, install one soundproof panel 4 from above between the pillars 2 to cover the periphery of the box using the method shown in Figure '3. Insert them one by one and stack them up, and also on the ceiling, insert the 3rd one for the channel steel beam 3.
Insert and secure the soundproof panels 4 one by one from the sides in the same manner as shown in the figure.

Although Fig. 3 shows an assembly method in which channel steel is used as the support column 2 and the soundproof panel is inserted into the groove, another method is to use bar-shaped steel material for the support column 2 as shown in Fig. 4. There is a method of assembling the soundproof panel 4 by inserting the holes 4a drilled in the soundproof panel 4, or as shown in FIG. It can also be implemented by fitting and assembling. Further, when disassembling the soundproof box after assembly, it can be easily disassembled by removing each component in the reverse order to the above.

Next, FIG. 6 shows a specific structure of the soundproof panel 4 having the split structure described above. That is, the soundproof panel 4 has an outer wall Fi8 (thickness 1.-6
m), on the inner surface there is a vibration-proof rubber 9 (thickness of about 3I), felt 10 as a sound absorbing material (thickness of about 25mm),
It is a laminated structure made by overlapping and assembling perforated gypsum board (thickness 6m, hole diameter 6am, hole pitch about 201), and each soundproof panel 4 has a size that can be easily carried by two workers. It is made with external dimensions that are heavy.

According to the soundproof panel 4 having such a laminated structure, the outer wall board 8 provides sound insulation, the vibration isolating rubber 9 provides vibration damping, the felt 10 provides sound absorption, and the perforated board 11 provides sound diffraction.

It has been confirmed that the synergistic effects such as the distance attenuation effect using reflection effects can significantly attenuate the noise that passes through the soundproof panel and propagates outward. In other words, according to the results of an experiment conducted to evaluate the soundproofing effect, the noise level of the sound source (press machine) was reduced to 95 dB (frequency 500 Hz).
As a result, the noise level outside the soundproof panel is 77 dB.
could be reduced to.

Furthermore, Fig. 7 shows an assembly structure that prevents sound from leaking outside the box between adjacent soundproof panels 4, and the soundproof panels 4 are stacked and assembled as explained in Fig. 2. At this time, an elastic filling 12 such as rubber or sponge is inserted between the overlapping parts of the panels to close the gap. Note that 13-=a double-sided adhesive tape for attaching the elastic filling 12 to the end surface of the soundproof panel 4. 'Furthermore, FIG. 8 shows a door 5 attached to the door 5 shown in FIG.
As shown in the figure, to suppress noise leakage outside the box,
An elastic packing 14 is attached to the end face of the door plate to close the gap between the W@. Note that 15 indicates a magneto-canch that temporarily adsorbs the door.

〔Effect of the invention〕

Since the soundproof box of the present invention is configured as described above, it has the following effects.

In the structure of claim 1, the soundproof panel covering the periphery of the soundproof box and the ceiling is divided into basic channel materials,
Since the soundproof panels are assembled one by one by inserting them into the frame made of pillars and beams, there is no need for cranes or welders to handle heavy objects during construction, and the manual labor of only a few workers is required. You can proceed with the assembly and disassembly of the soundproof box. Furthermore, assembly can be carried out even in factory buildings with low ceilings and no crane equipment.

Further, according to the configuration of claim 2, a soundproof panel with high soundproofing performance can be obtained.

Furthermore, by adopting the configuration of claim 3, it is possible to suppress noise leaking from inside the soundproof box to the outside even more effectively.
