BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof panel used when building a soundproof building or the like, and in particular, the soundproof panel is improved so that sound absorbing materials can be replaced. Is.

[0002]

2. Description of the Related Art At a civil engineering / construction construction site where construction is carried out using various types of equipment and devices, noise is prevented from being diffused by shielding the surrounding area with a soundproof building or a soundproof wall.

[0003] For example, at a construction site where a high-voltage electric wire is laid under the road surface, a pit is opened in order to remove soil under the road surface. At this time, noise generated by an excavator or the like is generated. The area around the eaves is shielded by a soundproof building to prevent diffusion.

By the way, a soundproof panel has been well known as a material used for building a soundproof building.

This soundproof panel is composed of a main body frame formed by bending a steel plate into a concave shape, a perforated plate having a plurality of small holes opened therein, and a sound absorbing material made of glass wool or the like.

FIG. 6 is a sectional view showing the soundproof panel.
In the figure, reference numeral 1 is the main body frame, 2 is a perforated plate, and 3 is a sound absorbing material.

As clearly shown in this figure, the perforated plate 2 and the sound absorbing material 3 are arranged on the side of the opening 1a of the main body frame 1, and the perforated plate 2 and the sound absorbing material 3 form a frame 4. It is fixed.

The frame 4 is welded to the body frame 1, and the perforated plate 2 is welded to the frame 4.

[0009]

However, according to the conventional soundproof panel described above, the frame is welded to the main body frame, and the perforated plate is welded to the frame so that the main body frame and the perforated plate are sandwiched. Since the sound absorbing material is arranged, even if the perforated plate is damaged due to long-term use or the sound absorbing material is contaminated, it is almost impossible to replace it.

By the way, contrary to the remarkable deterioration of the perforated plate and the sound absorbing material, the body frame has a large plate thickness and high strength, so that it can be used for a long period of time.

However, as described above, since it is impossible to replace the perforated plate and the sound absorbing material, when it deteriorates, it was forced to repurchase the entire soundproof panel including the main body frame having a high price composition ratio.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to improve the soundproof panel so that the sound absorbing material and the like can be easily replaced.

[0013]

DISCLOSURE OF THE INVENTION The present invention comprises a body frame having a concave shape, a perforated plate attached to the opening side of the body frame, and a sound absorbing material arranged between the perforated plate and the body frame. In a soundproof panel constituted by, a holding frame on which a plurality of crosspieces are installed is made detachable to the opening side of the main body frame, and the perforated plate is arranged between the crosspieces. The above object is achieved by providing a soundproof panel structure characterized in that the sound absorbing material is detachably locked to a porous plate.

[0014]

According to the soundproof panel structure of the present invention, the holding frame fixed to the main body frame can be removed from the main body frame by pulling out the screw which is the fixing member.

Further, a perforated plate is arranged between the crosspieces of the holding frame, and a sound absorbing material is locked to the perforated plate by a pin.

Therefore, it is possible to replace only the sound-absorbing material in a particularly heavily polluted portion, and when the deterioration of the entire perforated plate and the sound-absorbing material is remarkable, the whole including the holding frame can be replaced. .

[0017]

Embodiments of the soundproof panel structure according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing a soundproof building. Reference numeral 10 shown in the figure is a soundproof panel of the present invention.

By the way, although various works are carried out in the inside, the noise diffusion is prevented by the soundproof panel 10.

FIG. 2 is a plan view showing the soundproof panel 10. Reference numeral 20 in the drawing is a main frame, and 40 is a perforated plate.

As is clear from this figure, the soundproof panel 10 is provided with a vertically long main body frame 20, and has a rectangular shape as a whole.

The main body frame 20 is formed by bending a steel plate into a concave shape. The angle plates 21 and 21 are welded to both ends of the main body frame 20, and the holding frame 30 is arranged in the opening.

The holding frame 30 is formed by connecting the angled steels 31, ... In a rectangular shape and erected a plurality of crosspieces 33 ,. .. are fixed to the main body frame 20 with screws t or the like.

Further, as clearly shown in this figure,
Between the crosspieces 33, ... Of the holding frame 30, there are arranged perforated plates 40 ,.

Next, FIG. 3 shows a sectional view of the soundproof panel 10. Particularly, (a) is a sectional view taken along the line XX 'in FIG. 2 and (b) is a sectional view taken along the line YY' in FIG. The reference numeral 23 shown in the drawings and both drawings is the above-mentioned opening.

First, as clearly shown in FIG. 3A, ribs 25, 25 such as a square steel pipe are fixed along the main body frame 20 in the opening 23 of the main body frame 20, and Inside the perforated plate 40 arranged in the opening 23 of the main body frame 20, a sound absorbing material 50 made of glass wool or the like is arranged.

Further, the holding frame 30 is composed of the angle steels 3 on the left and right sides.
The perforated plates 40 are welded to the crosspieces 33 on both sides, while 1, 1 and 31 are locked to the edges of the opening 23.

Further, through holes 27, 27 are bored in the angle plate 21 welded to both ends of the main body frame 20, and each soundproof panel 1 is utilized by utilizing the through holes 27, 27.
It is possible to connect 0, ...

On the other hand, as clearly shown in FIG. 3 (b), the crosspiece 33 is fixed to the ribs 25, 25 by the screw t as described above, whereby the holding frame 3 is formed.
