2. Description of the Related Art Conventionally, a wall structure such as a soundproof wall has been installed along a road or a railway along a railroad or the like for the purpose of preventing vehicle noise and projections. Some of such wall structures are formed from opaque face plates made of metal or the like, but those formed from opaque face plates are shielded from surrounding scenery by the face plates. As a soundproof wall, a light-transmitting wall structure formed from a face plate made of a transparent or translucent light-transmitting plate such as a synthetic resin or glass is installed along a road or a railway. .

[0003]

As a structure of the wall structure, there is a structure in which an end of a face plate is directly fixed to a support member erected on a road surface by a bolt, but in particular, a transparent material such as synthetic resin or glass is used. In the case of a plate made of a face plate made of a light plate, the stress caused by the deflection caused by wind load etc. concentrates on the fixed part, and the free expansion and contraction due to thermal expansion etc. of the face plate is prevented, There is a problem that is damaged from the part that was.

Therefore, as shown in FIG. 13, for example, an L-shaped fixing member c is bolted to a web b in a concave groove of a supporting member a made of H-shaped steel, so that an inner surface of a flange e of the supporting member a and the fixing member c are connected to each other. There is also proposed an apparatus in which an end portion of a face plate f is interposed therebetween to movably support the face plate f, thereby preventing stress concentration due to a wind load and breakage due to expansion and contraction such as thermal expansion. However, in order to make the face plate f movable,
It is necessary to make the distance between the inner surface of the flange e of the support member a and the fixing member c larger than the thickness of the face plate f, but the face plate f is simply sandwiched between the flange e of the support member a and the fixation member c. Therefore, when the face plate f is made of a light-transmitting plate such as a synthetic resin or glass, there is a problem that the face plate f bends and falls off due to wind pressure or the like and drops.

Accordingly, the present invention solves the above-mentioned problems and provides a wall structure which prevents damage to the face plate due to stress concentration due to wind load and expansion and contraction such as thermal expansion, and also prevents falling due to deflection such as wind pressure. It will not be provided.

[0006]

In order to achieve the above object, the present invention has the following arrangement. That is, the wall structure according to the present invention is a support member erected at a predetermined interval, a face plate provided with a plurality of elongated holes elongated in the length direction at appropriate intervals in the height direction, A holding member provided with a bolt mounting hole corresponding to the long hole and having a retaining projection having a height higher than the thickness of the face plate on the back surface, and a face plate arranged along the support member. A holding member is provided on the front surface, a bolt inserted from a bolt mounting hole of the holding member and a retaining projection are respectively penetrated through a long hole of the face plate, and the bolt is attached to the supporting member and an upper end of the retaining projection is formed. The face plate is supported so as to be movable in the length direction within the range of the elongated hole between the support member and the holding member that is in contact with the support member and is wider than the thickness of the face plate. Things.

According to the present invention, the face plate is supported between the holding member and the support member having a width larger than the thickness of the face plate so as to be movable in the longitudinal direction within the long hole. The stress such as a wind load applied to the plate is dispersed, and the expansion and contraction of the face plate due to thermal expansion and the like are not hindered.

In addition, since the bolt inserted from the bolt mounting hole of the holding member and screwed to the supporting member and the retaining projection protruding from the back surface of the holding member penetrate through the elongated hole of the face plate, the wind pressure is increased. Even if the face plate is bent due to, for example, the face plate is locked by the bolt and the retaining projection, it is prevented from falling off between the holding member and the support member, and it is not necessary to attach a fall prevention member such as a fall prevention wire.

In the present invention, if the bolt mounting holes and the retaining projections provided on the holding member are separately formed, the face plate is locked by both the bolts and the retaining projections. The retaining projection may be hollow, and the hollow portion may be formed as a bolt mounting hole,
In such a form, the face plate is locked by the retaining projection,
The retaining projection is reinforced by a bolt inserted into a bolt mounting hole in the hollow portion.

In the present invention, in order to prevent the face plate supported between the holding member and the support member from rattling,
To the extent that the movement of the face plate is not impaired, insert a cushion material between the holding member and the face plate and between the face plate and the support member, or between the holding member and the face plate or between the face plate and the support member. It is preferable to keep it.

In the present invention, the face plate may be formed of an opaque plate such as a metal. However, if the face plate is formed of a transparent or translucent light-transmitting plate such as a synthetic resin or glass, the surrounding plate is formed by the face plate. This is preferable because sound can be shielded without being shielded.
