【発明が解決しようとする課題】ところで近年この種橋
梁における防音壁及び防風壁は巨大化しつつあり、橋梁
本体へ加わる風荷重は膨大なものとなり、橋梁の設計・
施工上さまざまな支障をきたしている。However, in recent years, the soundproof walls and windbreak walls of this type of bridge have become enormous, and the wind load applied to the bridge body has become enormous.
There are various obstacles in construction.
【０００４】とくに橋梁への動的な空力影響が橋種選定

て不安定走行を招く恐れがある。[0005] The windbreak wall has a greater effect of reducing the wind speed as the filling ratio of the material constituting the windbreak wall is higher. However, the wind speed changes greatly with respect to the running vehicle at the boundary of the installation section, and there is a possibility that the running may be unstable. .

A movable wall is provided, and the movable wall has a ventilation opening, and the opening and closing can be opened and closed with respect to the ventilation opening to apply the spring force. A lid for closing the ventilation opening is provided, and the movable wall is inclined to the inside of the bridge with the lower side as a hinge when the lateral force becomes higher than the wind speed at which the lid closes by applying a spring force. And

になれば壁の一部が傾き、風を上方に逃すようになる。In the wall structure of the present invention having the above structure,
At low wind speeds, the opening that opens to a part of the wall is open,
If the wind speed of the cross wind is large enough to hinder the safe driving of the vehicle or the walking of the rider, the opening ratio of the opening is reduced,
Furthermore, when the wind speed becomes high and the safety of the bridge itself becomes uneasy, a part of the wall is inclined and the wind escapes upward.

を十分に果すことができる。In the case of this embodiment, since it is a windbreak wall,
If the wind speed of the cross wind 8 received by the wall increases, the running of the vehicle will be hindered. Therefore, the lid 5 is closed, and if the wind speed further increases, the wind load on the windbreak wall causes a problem on the strength of the bridge. The wall 6 is tilted, and the crosswind 8 is released in the direction indicated by the dotted line 9 to reduce the wind load hitting the windbreak wall. In this case, since the wind entering the inside is directed upward, there is no problem in running the vehicle traveling inside the windbreak wall, and the role of the windbreak wall can be sufficiently fulfilled.

The movable wall is provided with a ventilation opening, and the opening and closing can be opened and closed with respect to the ventilation opening to open the ventilation opening at a low cross wind speed and close the ventilation opening when the cross wind speed increases. A movable lid is provided, and the movable wall is inclined toward the inside of the bridge with the lower side as a hinge when the wind force is higher than the wind speed at which the lid closes due to the application of a spring force. Since the wall can be reduced without impairing the purpose of the wall, the installation of the wall does not become a determining condition of the bridge type hull as in the past.
