Description

{SIDEWALK FOR PREVENTING DAMAGE DUE TO WIND PRESSURE}

More particularly, the present invention relates to a method of connecting a wind pressure distributing means in the form of a blind to a lower portion of a free end of an H beam for supporting a stern guiding, The present invention relates to a suspension for preventing damage due to wind pressure that can prevent breakage of the suspension by wind pressure.

Generally, on bridges and roads, it is common to construct concrete structures at both ends of the roads through which vehicles are traveling to form boundaries between roads and roads.

Therefore, it is difficult to secure a sufficient range of people to which a person can pass. Therefore, it is necessary to maintain the width of the existing roads and to install the roads to install the roads.

In the case of such a hypothetical delivery, in general, the outer side of the bridge structure is in contact with the river or the sea, and in the case of the road, since the underground structure for supporting the upper load is not constructed outside the road surface, It is a common practice to construct the cantilever structure with the concrete structures at both ends of the road as points.

However, such a hypothesis leads to the problem that the walk deck is damaged by the wind pressure of the strong wind when the seal passes.

Especially, the H beam or the girder of the hypothetical guide is bent by the upward wind pressure generated on the concrete wall surface outside the road or the bridge, and the walking deck is frequently broken, which causes a large cost for the maintenance cost.

In the conventional patent literature, there is a "suspension of bridges and roads (patent registration no. 1353753) ", and such a conventional hypothetical guide has only a durability-oriented point of view but no coping structure against wind pressure.
