2. Description of the Related Art Conventionally, as a soundproof wall 110 provided as a measure for preventing noise generated from a road, one shown in FIGS. 13 and 14 is known. This sound barrier 110 is on the road 1
A plurality of H-shaped steels 120 as columns are erected at predetermined intervals along the road edge 100s of 00, and the soundproofing means 130 is fitted from above between the recesses 120a and 120a facing each other between the H-shaped steels 120 and 120. It consists of The H-shaped steel 120 is formed by connecting a wide flat plate 120A facing the road 100 side to the left and right with another flat plate 120B by a connecting plate 120C so as to face each other.
The surface of 20 facing the road side is the front surface portion 120f. On the lower side, which is the road surface side between the H-section steels 120, 120, a side wall 110B made of concrete or the like is provided for stabilizing the H-section steel 120. The soundproofing means 130
The sound absorbing material 140 such as a non-woven fabric formed in a rectangular shape is housed in a slightly larger aluminum case 150 or the like. The case 150 is composed of a bottomed storage container 150A for storing the sound absorbing material 140 and an upper lid 150B. A plurality of through holes 150s for sound absorption by the sound absorbing material 140 are formed on the entire surface 150f of the storage container 150A. Has been done.

However, the above soundproof wall 110 is
U-shaped recesses 120a, 120a of shaped steels 120, 120
Since the soundproofing means 130 is fitted between them, the flat plate 120 that is wide on the left and right sides of each H-section steel 120 facing the road 100 side.
The surface portion 120f of A remains exposed on the road 100 side, and sound propagates through the exposed surface portion 120f so as to wrap around and leaks to the outside of the road 100,
Since the light is reflected to the road 100 side, there is a problem that the sound absorbing efficiency of the soundproof wall 110 is deteriorated.

Therefore, the applicant of the present application has proposed the following soundproofing means. As shown in FIG. 14, in this soundproofing means, in the sound absorbing material 3 made of a plate-shaped fiber molded body, a rectangular notch 3c extending along both ends on one surface side is provided. The sound absorbing material 3 is formed and functions as the soundproofing means 4. As shown in FIG. 14, the soundproofing means 4 is used for a soundproofing wall that is vertically installed at predetermined intervals along the road edge 100s of the road 100 as a noise source, and faces the road 100 side. In contrast to the H-shaped steel 120 as a column having the surface portion 120f of the wide flat plate 120A,
It is attached so as to cover the surface portion 120f from the f side.
The plurality of soundproofing means 4 are attached in the vertical direction between the H-section steels 120, 120. Therefore,
The soundproofing means 4 is such that the covering surface and the contact surface of the soundproofing means 4 come into contact with the half surfaces 120fh, 120fh and the side walls 120s, 120s of the adjacent H-section steels 120, 120, respectively.
By mounting the H-shaped steel 120 between the H-shaped steels 120 and 120, the H-shaped steel is applied to each covering surface of each soundproofing means 4 which is mounted adjacent to the left and right.
It is possible to assemble a soundproof wall in which the surface portion 120f of the shaped steel 120 is covered. Thereby, the surface portion 1 of the H-section steel 120
Since 20f is covered with the sound absorbing material 3, sound can be efficiently absorbed, so that a soundproof wall having higher sound absorbing efficiency than the conventional one can be obtained.

[0005]

With this structure, however, it is necessary to form the notch 3c in the sound absorbing material 3 with high precision, but if this was relied on by hand, mass production would be difficult. Quality cannot be achieved and the yield will be deteriorated.

[0027]

According to the plate-shaped member processing apparatus of the first aspect of the present invention, there is provided a first cutting device for making a cut from the one surface of the plate-shaped member in the other surface direction. Since a second cutting device for making a cut from the end of the plate-shaped member toward the central portion is provided, for example, in the sound absorbing material used for soundproofing means, on the left and right end surface sides, The notch for forming the rectangular notch extending along the end of the sound absorbing material can be easily and accurately formed. According to the plate-shaped member processing apparatus of claim 2, since the plate-shaped member is processed by molding a resin material, a rubber material, or a foamed body or a fiber molded body thereof, the same effect as described above. Can be obtained.
According to the plate-shaped member processing device of the third aspect, since the cutting device for forming the end portion of the plate-shaped member is provided, the notch is formed and the sound absorbing material is formed into a predetermined length. Can be formed. In the plate-shaped member processing apparatus according to claim 4, since the cutting device is arranged such that the inclinations of the cutting blades of the cutting blades that cut each end portion are opposite to each other, when cutting the sound absorbing material. You can keep straightness without shifting the cutting position to either left or right,
It is possible to accurately form the left and right end faces. Since the plate-shaped member processing apparatus according to claim 5 includes the movable table on which the plate-shaped member is placed and which is movable toward the cutting devices and the cutting device, the processing operation can be performed smoothly. The workability can be improved. Since the plate-shaped member processing apparatus according to claim 6 is provided with the third cutting device extending between the both ends on one surface of the plate-shaped member, a plurality of cuts for bending the sound absorbing material are formed. It can be easily formed. Since the plate-shaped member processing apparatus according to claim 7 includes angle adjusting means for setting the inclination angle of the cutting blade of each of the cutting devices or the cutting blade of the cutting device, cutouts of various shapes, etc. It is possible to make a notch to form the. The plate-shaped member processing method according to claim 8 forms the notch between the notch formed by the first notch device and the notch formed by the second notch device. Since the holding part that holds the rectangular cutout is left, when the processed sound absorbing materials are stacked and transported to a predetermined place, the upper part of the cutout is It is possible to prevent deformation or the like due to the weight of the material or the like.
