DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the soundproof panel according to the present invention will be described.
This will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a soundproof panel and a connection structure thereof according to an embodiment of the present invention. In this connection structure, a plurality of soundproof panels are arranged side by side, and two adjacent soundproof panels are sequentially connected in a state where the side end faces thereof abut each other, thereby forming a wall of the soundproof room.

First, the soundproof panel will be specifically described. The illustrated soundproof panels 20, 20, and 20 are formed by processing a plywood or a gypsum board having a sound absorbing property into a square shape, and are mounted on the base 10 with a sound insulating material that prevents a gap therebetween. The end face of the connection end on both the left and right sides of each soundproof panel 20 has
A pair of grooves 24 for accommodating 0 are formed. The hijack 60 includes a pair of connected soundproof panels 20, 2.
It is fitted in the space between 0 and increases the number of times the sound is diffracted at this connecting portion to enhance the soundproofing effect.

A pair of lower cutouts 22 are formed on the left and right connecting end sides of the lower end of each soundproof panel 20. Each lower cutout 22 is obtained by cutting a rectangular parallelepiped region from a predetermined position of the edge of the panel material of the soundproof panel 20, and the soundproof panel 20 weighing 40 kg or more is mounted on the base 1.
It has a supporting strength that can withstand a pulling load required to slide rightward or leftward on zero. Further, a pair of upper cutouts 23, 23 are also formed on the left and right connection end sides of the upper end of each soundproof panel 20. Each upper notch 23 is
Like the lower notch 22, the panel material of the soundproof panel 20 is cut out and has a supporting strength enough to withstand a pulling load necessary for sliding the soundproof panel 20 rightward or leftward on the base 10. .

Next, a connector for connecting the above soundproof panels will be described. A pair of adjacent soundproof panels 2
The reference numerals 0 and 20 are connected to each other by a base plate 50 and an upper plate 51 which are connecting tools. The lower portions of a pair of opposing connection ends of the adjacent soundproof panels 20 and 20 are formed by a base plate 50 made of a square iron plate.
The soundproof panels 20 and 20 are fixed in a state where the end faces of the connection ends of the bases 20 abut each other, and in which the front faces of the base 10 and the panel faces of the soundproof panels 20 and 20 are matched. On the other hand, soundproof panel 2
The upper ends of the pair of connection ends 0 and 20 are in a state where the end faces of the connection ends of the soundproof panels 20 and 20 are abutted by the upper plate 51 made of an elongated iron plate, and the panel surfaces of the soundproof panels 20 and 20 are matched. Fixed at.

Hereinafter, a method of connecting the soundproof panels of the embodiment will be described. It is to be noted that the steps after the stage in which the fixing of the right connection end of the soundproof panel (A) 20, which is entirely shown on the right side of the drawing, has been completed will be described.

First, the base plate 50 is attached to the base 10 using four screws, and then the base plate 50 is mounted.
The front of the base 10 and the soundproof panel (A) 2 are fixed by screwing the soundproof panel (A) 20 using two screws.
These are fixed to each other in a state where they are matched with the panel surface of No. 0.

Next, the hiring wrench 60 is fitted into the groove 24 formed on the end face of the left connection end of the soundproof panel (A) 20, and the soundproof panel (B) 20 on the left side of the drawing is soundproofed at the right connection end. The panel (A) 20 is disposed so as to be close to the left connection end and that the panel surface substantially matches the front surface of the base 10. In this case, the soundproof panel (B) 20 is arranged at a position considerably separated from the soundproof panel (A) 20 by manual work or the like, and is arranged along the longitudinal direction of the base 10.
It may be moved until it approaches zero.

Next, the claws of a pair of pulling tools (a gripper such as a so-called brushed metal or a vise such as a solitary hand) shown in FIG.
2, 22 and the upper notches 23, 23 are respectively bitten (only the upper pulling tool is shown), and these are operated to
Connect the right connection end of the soundproof panel (B) 20 to the soundproof panel (A).
20 gradually approach the left connecting end. Thereby, the end face of the left connection end of the soundproof panel (A) 20 and the soundproof panel (B)
The end faces of the right connection ends of the 20 can be abutted against each other and firmly adhered to both the upper and lower sides.

The soundproof panel 20 of the above embodiment is as heavy as 40 kg or more, and a sound insulating material for preventing slippage is sandwiched between the soundproof panel 20 and the base 10. There is friction resistance. Therefore, the end face of the soundproof panel (A) 20 and the soundproof panel (B) 2
It is extremely difficult to bring the zero end face into close contact. However, the lower cutouts 22, 22 and the upper cutouts 23, 23, which can be formed easily and inexpensively, are provided in the soundproof panel 20 in advance, and are drawn by a simple pulling tool 70 attached to these cutouts 22, 23. Thus, the soundproof panel (A) 20 and the soundproof panel (B) 20 can be relatively easily brought into close contact with each other.

Thereafter, with the pulling tool attached, the soundproof panel (B) 20 is screwed to the base plate 50 fixed to the base 10 using two screws, and four screws are further used. And soundproof panel (A) 20
The upper plate 51 is screwed so as to straddle the upper end of the soundproof panel (B) 20 from the upper end of the upper end of the soundproof panel (B) 20.

First, the soundproof panel (B) 20 is screwed to the base plate 50, so that the front surface of the base 10 and the panel surface below the connection end of the soundproof panel (A) 20 are formed.
The panel surface at the lower part of the connection end of the soundproof panel (B) 20 can be accurately matched. Also, soundproof panel (A) 2
0 and the upper end of the connection between the soundproof panel (B) 20 and the upper plate 5.
Soundproof panel (A) by screwing through 1
20 and a soundproof panel (B) 20
Can be accurately matched with the panel surface at the upper end of the connection end. At this time, leave the pulling tool attached,
Since the plates 50 and 51 are screwed in a state where the end face of the left connection end of the soundproof panel (A) 20 and the end face of the right connection end of the soundproof panel (B) 20 are firmly adhered, the pulling tool is removed. After that, the soundproof panel (A) 20 and the soundproof panel (B) 20 are fixed in a state where they abut each other, and the same or higher sound insulation can be maintained as in the related art.

By repeating the above steps, the soundproof panel can be sequentially connected to assemble the soundproof room.

As described above, according to the soundproof panel 20 of the above embodiment, the pair of soundproof panels 20 and 20 can be easily formed by using the simple pulling tool 70 such as a vise and the inexpensive plates 50 and 51. It can be closely attached and fixed, and the sound insulation of the soundproof wall connecting them can be enhanced without impairing the workability. Moreover, in this case, the opposed connection ends of the pair of soundproof panels 20, 20 are connected to the plates 50, 51.
These soundproof panels 20 can be easily aligned with each other simply by pressing them, so that not only the left and right but also the front and rear directions can be accurately aligned and fixed.

Although the present invention has been described with reference to the embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the cutouts 22 and 23 are formed on the inside (indoor side), but may be formed on the outside.

In the above embodiment, the notches 22, 23
Are formed as depressions at the upper and lower edges of the soundproof panel 20, but the position thereof can be set arbitrarily on the soundproof panel 20 as long as the pair of notches 22, 22 face each other. Anything can be used as long as it can withstand. However, from the viewpoint of workability of the soundproof panel 20, a simple shape is preferable.

Further, the notches 22 and 23 may be formed as through-hole notches penetrating between the front and back panel surfaces of the soundproof panel 20. However, in the case of a through-hole type notch, it is necessary to close the notch hole for sound insulation after connection.

[0029]

As described above in detail, according to the soundproofing panel of the present invention, a pair of notches formed opposite to each of a pair of soundproofing panels arranged close to each other on the base are provided. By biting a suitable pulling tool such as a vise and gradually pulling both soundproof panels, the end faces of the connection ends of these soundproof panels can be abutted against each other in a state of being in close contact with each other. In this state, a pair of soundproof panels can be easily and simply attached with their connecting ends in close contact by passing a simple and inexpensive fixing means such as a fixing plate between the connecting ends of the pair of soundproofing panels and screwing them. It can be fixed at low cost. In addition, since such a notch can be formed by simple processing, the soundproof panel itself is relatively inexpensive. Also, in this case, by pressing opposing connection ends of the pair of soundproof panels against a fixing plate or the like, these panel surfaces can be easily matched, so that
The connection end of each soundproof panel can be accurately aligned and fixed not only in the left and right directions but also in the front and rear directions.
