  1 to 10, reference numeral 1 denotes a support made of H-shaped steel, and the sound insulation panel 2 is attached to the front side flange 1a of the support 1 as described later. At the back of the front side flange 1 a of the support 1, stoppers 3 are provided so as to protrude at every height interval of the sound insulation panel 2.

  In addition, the support | pillar 1 is not limited to H-shaped steel, Shaped steels, such as I-shaped steel and channel steel, may be sufficient.

  In FIG. 2, the front side (main line side) is shown by (A), and the back side (private land side) is shown by (B) (the same applies hereinafter).

  The stopper 3 is an L-shaped protrusion provided on the back surface of the front side flange 1a, and the mounting member 9 described later inserted from the upper end of the front side flange 1a enters and is mounted. The panel 2 is held at a predetermined height position of the support 1. The stopper 3 may be a bolt fixed to the front side flange 1 a by a nut other than the L-shaped protrusion.

  The stopper 3 may be composed of an opening (not shown) formed in the front side flange 1 a and a projection (not shown) inserted into the opening provided in the mounting member 9 in a protruding manner. .

  2 is a sound insulation panel. The sound insulation panel 2 is mounted on the back side of the frame 5 and the frame 5 consisting of a plate-shaped sound insulation 4, an upper frame 5 a, a lower frame 5 b and a vertical frame 5 c attached around the sound insulation 4. And the back plate 6. The sound insulating material 4 is made of a sound absorbing material made of a polyester fiber molding material. Note that the sound insulation material 4 may be a translucent material made of a resin plate. When the sound insulating material 4 is a light transmitting material made of a resin plate, the back plate 6 becomes unnecessary. In this case, the wire holding fixture 13 described later is attached to the back surface side of the light transmitting material.

  Reference numeral 7 is a mounting means for mounting the sound insulation panel 2 between the columns 1. The attachment means 7 is attached to the vertical frame 5c of the frame 5 by the bolt 8 and the U-shaped attachment member 9 through which the front side flange 1a of the support 1 is inserted, the front surface of the front side flange 1a and the attachment member 9 And a fixing spring 10 for fixing the sound insulation panel 2 by pressing the mounting member 9 against the front side flange 1a. The length of the attachment member 9 may be the total length of the plurality of sound insulation panels 2. Thereby, the number of stoppers 3 can be reduced.

  The fixing spring 10 is fixed to the inner surface of the front plate 9a of the mounting member 9 by a bolt 11 (see FIGS. 1 to 4). At the end of the front plate 9a, a flange 9c is formed by bending the front plate 9a inward at a right angle. The flange 9c abuts on the front side flange 1a of the support 1 (see FIG. 1).

  A notch 9b is formed in the flange 9c of the portion to which the fixing spring 10 is attached (see FIG. 1). The notch 9 b is an insertion port of a tool such as a driver used when folding and unfolding the fixing spring 10.

  The fixing spring 10 is formed by spirally bending a plate spring as shown in FIG. 7 to FIG. 9, and one end (M) has a bolt hole 10a through which the bolt 11 is inserted, and A first engagement piece 10c provided with an opening 10b into which the two engagement pieces 10d are inserted is formed. The first engagement piece 10c is formed by punching out a part of the fixing spring 10 in the lower part of the bolt hole 10a.

  The other end (N) of the fixing spring 10 is bent in a mountain shape, and a second engagement piece 10d is formed on the upper part of the bent portion by punching out a part of the fixing spring 10 outward. ing.

  As shown in FIG. 9, in order to fold the fixing spring 10, the other end (N) of the fixing spring 10 is elastic until the second engagement piece 10d is inserted into the opening 10b of the first engagement piece 10c. It resists the inside and pulls it against the force. Thereby, the fixing spring 10 can be folded.

  On the other hand, in order to release the folding of the fixing spring 10, the other end (N) of the fixing spring 10 is from the state shown in FIG. 9 until the second engagement piece 10d is released from the opening 10b of the first engagement piece 10c. Move further inside. Thereby, the folding of the fixed spring 10 can be released.

  The folding operation of the fixing spring 10 and the releasing operation of the folding can both be performed by inserting a tool such as a driver from the notch 9 b formed in the mounting member 9.

  Reference numeral 12 denotes a fall prevention wire which is stretched vertically along the support 1 and prevents the sound insulation panel 2 from falling. The fall prevention wire 12 is inserted into a wire holding fitting 13 attached to the back plate 6 of the sound insulation panel 2 and formed of a J-bolt described later.

  Numeral 13 denotes a wire holding fitting consisting of a J-bolt through which the fall prevention wire 12 is inserted, and is attached to the back plate 6 of the sound insulation panel 2 via a bolt 14 at an interval. Note that the number of wire holding brackets is not limited to two. As described above, since the fall prevention wire 12 is stretched on the back plate 6 side of the sound insulation panel 2, the fall prevention wire is compared with the case where the fall prevention wire 12 is stretched in the column 1 of H-shaped steel. 12 inspections can be done easily.

  Further, as shown in FIG. 3, a gap for removing the fall prevention wire 12 is obtained between the wire holding fitting 13 and the back plate 6 by using J-bolts having different lengths as the wire holding fitting 13 (see FIG. 3). P) can be opened, so the noise insulation panel 2 can be easily removed. That is, when the J-bolt 14 is loosened and separated from the back plate 6, a gap (P) can be opened between the short end of the J-bolt and the back plate 6.

  The sound insulation wall of the present invention, which is configured in this manner, is constructed as described below.

  The folded fixed spring 10 is fixed to the inner surface of the front plate 9 a of the mounting member 9 by a bolt 11.

  Then, the mounting member 9 to which the fixing spring 10 is fixed is fixed to the vertical frame 5 c of the sound insulation panel 2 by the bolt 8.

  Then, the mounting member 9 is inserted along with the sound insulation panel 2 from the upper end of the front side flange 1 a of the support 1. Since the stopper 3 is attached to the front side flange 1a, the sound insulation panel 2 is inserted until the mounting member 9 abuts on the stopper 3 as shown in FIG. At this time, the fall prevention wire 12 is inserted into the J bolt as the wire holding fixture 13.

  Next, a tool such as a driver is inserted from the notch 9b (see FIG. 1) of the flange 9c of the mounting member 9, and the fixing spring 10 is further inserted until the second engagement piece 10d is released from the opening 10b of the first engagement piece 10c. Move the other end (N) inward. As a result, since the folding of the fixing spring 10 is released, the sound insulation panel 2 is fixed to the support 1 by the elastic force of the fixing spring 10.

  After the above operation is performed for each sound insulation panel 2, a sound insulation wall is constructed by fixing the fall prevention wire 12.

  When replacing with a new sound insulation panel, some of the sound insulation panels 2 are damaged due to an accident etc., after removing the damaged sound insulation material 4, remove the bolt 8 and loosen the J bolt as the wire holding bracket 13 , Remove the fall prevention wire 12 from the gap (P). Then, the fixing spring 10 is folded or slid toward the center of the support interval to remove the mounting member 9 from the support 1. Thereafter, if a new sound insulation panel is attached, the damaged sound insulation panel 2 can be easily and quickly replaced.

  As described above, according to the present invention, installation, replacement, and inspection of the sound insulation panel 2 can be easily performed by not using a bolt for mounting the sound insulation panel 2 to the support 1.

  Further, according to the present invention, by covering the fall prevention wire 12 of the sound insulation panel 2 on the back plate side of the sound insulation panel 2, the fall prevention wire 12 of the sound insulation panel 2 can be easily checked.

  Further, according to the present invention, the use of the J-bolt as the wire holding fixture 13 facilitates the removal of the sound insulation panel 2 from the fall prevention wire 12.
