って落下する危険性があった。本考案はこれらの課題を
解決しようとするものである。Since the conventional soundproof wall is made of a metal material, the soundproof wall reflects radio waves and causes reflection failure. In addition, since the constituent members are separated and have many members, man-hours such as drilling and riveting are required to assemble into the final product, which increases the cost, and further, all the members are passed through the fall prevention wire. Is not necessarily
If the rivets come off due to a car collision, there was a risk of falling apart and falling. The present invention is intended to solve these problems.

すると、両者の係止を簡単にできる。[0007] The sound absorber inserted into the molded body absorbs sound energy and does not transmit it to the back. Since both of these are radio wave permeable, they do not reflect radio waves and do not cause radio interference. An integrated sound-absorbing and sound-insulating wall is defined as one unit, and an arbitrary number of the sound-insulating walls are stacked to form a sound insulating wall of a required height. If a member for preventing the guide pipe from coming off is provided in the vicinity of a portion where the guide pipe penetrates the main body molded product, it is possible to easily lock both members.

ダウンにつながる。According to the present invention, since the molded body and the sound absorber are made of a radio wave permeable material, they do not reflect radio waves and are extremely effective as sound barriers for preventing radio wave interference. In addition, the required strength is obtained by the box-shaped integral structure, even with synthetic resin properties that are less rigid and stronger than metal.
It can be formed by an extrusion molding method or a drawing molding method.
In addition, the integrated structure, which is not just a box structure, is a strong and stable structure from the standpoint of strength and molding from the standpoint of strength and molding. The cost is reduced due to the reduction in the number of assembly steps.
