[0002]

2. Description of the Related Art Conventionally, a corrugated iron plate or an iron plate with slits is usually used as a sound insulating / windproof wall plate for a soundproof / windproof wall (such as a soundproof wall or a windbreak fence). A resin plate with a raised cord is applied.
Further, the above-mentioned iron plate is arranged in contact with the front surface of each of the shaped steel columns that are built with a gap and is fixed by washers or bolts.
The translucent resin plate is formed into a width size corresponding to the interval between the shaped steel columns, and at least both side portions are provided with reinforcing frames to form a panel, and both side portions with the reinforcing frames are attached to each shaped steel column (H-shaped steel). It is fitted between the flanges and fixed by bolts.

[0003]

As described above, the conventional sound-insulating / wind-proof wall sound-insulating / wind-proof wall plate is brought into contact with the front surface of the shaped steel column or both sides are fitted between the flanges of the shaped steel column. Since they are fixed with bolts, the fixing is gradually loosened due to vibration and bending of the wall plate, or the load dropped from the running vehicle may collide and fall off due to this impact. Therefore, the development of this fall prevention measure has become an issue.

As a measure for preventing the above-mentioned fall, sound insulation and
It is conceivable that multiple pairs of horizontal members (wire ropes, plates, pipes, etc.) may be attached to the front and rear sides of the windbreak plate with a vertical gap between them to sandwich the members. Therefore, there is a problem that the cost is high and the translucent resin plate has a reduced translucency and a reduced field of view.

The present invention was developed in order to solve the above-mentioned problems. The object of the present invention is to fix a sound insulating / windproof wall plate to the front surface of a shaped steel column with a contact plate and bolts. Then, insert the wire rope into the shaped steel column and connect both ends to the left and right sides of the sound insulation and wind barrier plate, and assemble it to improve the placement performance and fall prevention performance and reduce cost. To provide a fall prevention device.
