Description

[Detailed explanation of the idea] The present invention relates to an improvement of a soundproof box.

Recently, as a noise prevention measure for press machines, compressors, etc., these machines are covered with prefabricated soundproof boxes whose walls and ceilings are assembled using soundproof panels, columns, beams, etc.

However, most of these conventional prefabricated soundproof boxes have the following problems.

■ The gap between the soundproof panel and the pillar cannot be completely closed, leading to noise leakage and the soundproofing function being insufficient.

■ Because the columns and beams have multiple shapes, processing costs are high;
It cannot be manufactured cheaply.

■ Construction is difficult because assembly requires work at height.

The present invention has been made to solve these problems, and aims to provide a soundproof box that has excellent soundproofing functions, can be produced at low cost, and is easy to install.

The soundproof box according to the present invention has a plurality of soundproof panels that are equipped with sound absorbing material inside, a perforated plate on the inner surface, and recesses formed on both ends, and are arranged vertically in parallel, and a seal is placed between the recesses of each soundproof panel. After fitting groove-shaped closing materials that fix the materials to the outer surfaces of both sides, L-shaped frame materials are arranged at the upper and lower ends of the inner and outer surfaces of the vertically arranged soundproof panels, and bolts are installed. They are connected with nuts, and one side of each large and small angle-shaped column is overlapped with the outer and inner surfaces of one end of the vertically arranged soundproof panels, respectively, and connected with bolts and nuts. A plurality of the above-mentioned soundproof panels are arranged horizontally, and a groove-shaped sealing material is fitted between the recesses of each soundproof panel to fix the sealing material to both sides, and then the soundproof panels are arranged horizontally. Place the upper sides of tall frame members on both the left and right outer edges of the soundproof panels, connect them with bolts and nuts, and then place L-shaped frames on the tops of the front and rear ends of the horizontally arranged soundproof panels. A ceiling panel is constructed by arranging the frame material facing downward, a U-shaped frame material with a closing plate bent at both ends on the bottom surface, and a sealing material fixed on the outer surface of the upper side, and connecting these with bolts and nuts. are characterized in that the panels are connected with a sealing material interposed between the joint surfaces of each panel.

Align the bolt holes 15 and connect them with bolts and nuts.
Bolt hole 24 in the middle of one side of the upper column 10°10'
The wall panels 26 are assembled by connecting them with bolts and nuts as shown in FIG. 3.

Four wall panels 26 are assembled using the same procedure.

However, in order to assemble the soundproof box of the present invention using the ceiling panel 25 and four wall panels 26 assembled on the ground, first set up the four wall panels 26 at the required installation positions, and then Only the wall panel 26 is erected by fastening the frame member 8.9 at the lower end to an anchor (not shown) on the floor.

Next, the other end of the adjacent wall panel 26, that is, the pillar material 10
．． 10' is not attached to the side edge of the soundproof panel 1',
Align the bolt holes 24 at both the upper and lower ends of the pillar members 10 and 10' with the bolt holes 23 at the other ends of the frame members 6°7, 8, and 9 and the bolt holes 15 of the soundproof panel 1' arranged outside, and bolt. Connect with nuts, and bolt the intermediate bolt holes 24 on the other sides of the pillars 10, 10'.

Connect with nuts.

Then, the frame members 8 and 9 at the lower end of the wall panel 26 are fastened and fixed to anchors (not shown) on the floor.

Thereafter, the wall panels 26 are sequentially joined in the same manner to assemble the peripheral wall.

Next, between the upper ends of the pillars 10 and 10' at the four corners of this peripheral wall,
After fitting the corners of both ends of the frame members 3, 4.5 around the ceiling panel 25, the ceiling panel 25 is placed on the upper end of the peripheral wall, and the soundproof box 27 is assembled as shown in FIG.

In the soundproof box 27 of the present invention assembled in this way, there is a recess 13 at the side end of each soundproof panel 1' between the soundproof panels 1' making up the wall panel 26, as shown in FIG. It is completely sealed by the sealing material 17 fixed to both sides of the sealing material 2' fitted in between, and the soundproof panel 1'
The space between the inner pillar 10' and the inner pillar 10' is completely sealed by sealing material 17 fixed to the outer surface of both sides of the pillar 10'.
Further, the lower end of the wall panel 26 has a sealing material 17 fixed to the outer surface of one side of the frame member 8 at the inner lower end, as shown in FIGS. 6 and 7.
completely blocked by.

Moreover, between the wall panel 26 and the ceiling panel 25, the sixth and seventh
As shown in the figure, the space between the soundproof panels 1 composing the ceiling panel 25 is completely sealed by the sealing material 17 fixed to the bottom surface of the lower side of the frame members 4 and 5 around the ceiling panel 25. are completely sealed by sealing materials 17 fixed to both sides of the closing material 2 which is fitted between the recesses 13 at the side ends of each soundproof panel 1 in the same manner as described above.

Furthermore, the space between the side edges of the soundproof panel 1 on both the right and left sides of the ceiling panel 25 and the frame member 5 is completely sealed by sealing material 17 fixed to the inner surface of the upper side of the frame member 5, as shown in FIG. Furthermore, the space between the frame material 4 at the front and rear ends of the ceiling panel 25 and the front and rear ends of each soundproof panel 1 is completely sealed by a sealing material 17 fixed to the upper surface of the upper side of the frame material 4, as shown in FIG. It's blocked.

Therefore, the soundproof box 27 of the present invention prevents internal noise from leaking.

In addition, in the soundproof box 27 of the present invention, the pillar material 10.
10' gap, internal space of closing material 2, ceiling panel 25
, the recess 13 around the wall panel 26, the internal space of the frame members 4, 5 around the ceiling panel 25, etc. may be filled with sound absorbing material.

Further, the soundproof panels 1, 1' may have a structure including an air layer and a sound absorbing material.

As can be seen from the above explanation, the soundproof box according to the present invention is
This occurs internally because the space between the ceiling panel and the surrounding wall panels is completely sealed with sealant, and the gaps between the members that make up each panel are completely sealed with sealant. It does not leak noise and has excellent soundproofing properties.

In addition, the soundproof box of the present invention has an extremely simple structure in which the closing materials, frame materials, pillar materials, etc. that make up the ceiling panels and wall panels can be easily processed at low cost, reducing the cost of the soundproof box. can be achieved.

Furthermore, the soundproof box of the present invention requires only assembling the ceiling panels and wall panels on the ground, then standing them up and joining them together, so there is very little work at heights and the construction is easy.
