2. Description of the Related Art In many cases, bullet trains, conventional railway overpasses, high-speed overpasses, and the like are built through urban areas, and their noise has become a serious problem as it hinders the living environment.
For that purpose, there is an increasing demand for providing sound insulation walls such as cement plates or the like for the purpose of sound insulation, for the purpose of safety to prevent inadvertent entry, etc., or from a visual point of view. .

FIGS. 5 and 6 show a well-known conventional soundproof wall.
This soundproof wall is formed by inserting a small mouth portion 54a of a soundproof wall 54 into a pair of flange portions 53a of an H-shaped steel material 53 which is firmly uprightly attached to a ground cover 51 via bolts 52 or the like. The soundproof wall 54 is formed of the H-shaped steel 53
It is a structure to hold.

[0005] The above-mentioned soundproofing wall 54 has an H
It is attached to these H-shaped steel members 53 by a method of being inserted into the flange portion 53a of the molded steel member 53 from above, a so-called dropping method.

[0006] The soundproof wall 54 supported by the H-shaped steel material 53 as described above does not fall off due to the wind pressure of a typhoon or the like, and the H-shaped steel material 53 and the soundproof wall 54 are protected against displacement due to thermal expansion or the like.
As shown in FIG. 6, a wedge is formed in the gap between one flange 53a of the H-shaped steel member 53 and the small opening 54a of the soundproof wall 54 inserted in the flange 53a so as to be able to follow the difference in the behavior. The mold rubber material 55 is inserted from both sides of the web portion 53b of the H-shaped steel material 53 and sandwiched.

The wedge-shaped rubber members 55 on both sides are
A hole 56 provided in the web portion 53b of the H-shaped steel material 53
Are connected to each other by bolts 57
In this way, it is attached so as not to fall off between the flange portion 53a of the H-shaped steel material 53 and the small edge portion 54a of the soundproof wall 54. As described above, the gap between the small surface of the soundproof wall 54 fixed by the flange portion 53a and the wedge-shaped rubber material 55 and the web portion 53b of the H-shaped steel material 53 enables It is customary that a certain gap b is formed in design and construction.

[0008]

However, as described above, the small face of the soundproof wall 54 and the web portion 53b of the H-shaped steel material 53 are used as described above.
A gap b must be provided in the design between
The provision of the gap b results in the formation of an unexpectedly large gap b when an error in construction accuracy occurs, and the back surface of the soundproof wall 54 and the flange portion 5 of the H-shaped steel material 53 as described above.
There was a shortage of the margin a due to the surface of 3a, and there was a concern that the soundproof wall 54 would fall off from the H-shaped steel material 53.

That is, since the soundproof wall 54 is attached to the H-shaped steel material 53 erected on both sides by the dropping method as described above, the small face of the soundproof wall 54 and the web portion 53 of the H-shaped steel material 53 are provided.
It is necessary to provide a gap b to some extent between the H-shaped steel material 53 and the vertical position of the H-shaped steel material 53, or an error occurs in the accuracy of the vertical position. An excessively large gap b is formed, which causes the shortage of the above-mentioned clearance a, and there is a concern that the soundproof wall 54 may fall off the H-shaped steel material 53.

Further, since the right and left ends of the sound-insulating wall 54 are attached to the H-shaped steel member 53 in the same structure, when an external force is generated during an earthquake or the like, the sound-insulating wall is shifted to one side.
There is a concern that the shortage of the margin a on the opposite side will increase, and eventually the margin a will be extremely reduced, and there is also a concern that all the margin a will disappear, and the danger that the soundproof wall 54 will fall off is predicted. there were.

The wall falling-off preventing member and the wall mounting structure according to the present invention are a completely new technology developed in view of the above-mentioned conventional problems, and are simple and reliable without changing the conventional soundproof wall structure. If the vertical position and accuracy of the H-shaped steel material have errors, or if the sound-insulating wall is displaced by an external force during an earthquake or the like, the surface of the sound-insulating wall and the flange of the H-shaped steel material can be mounted. The present invention provides a completely new technology that always secures a certain amount of interference with the surface, thereby preventing the wall from falling off.
