In this case, bicycle roads can not be used for a part of existing roads or parts of India, resulting in complaints due to inconveniences of users on the roads or in India. , The road width was limited when the existing bridge was changed to a bicycle road.

Therefore, construction is carried out in the form of receiving bicycle roads along side the roadway already constructed, or reducing the restriction of the space by constructing the roadway.

As an example of such a technique, a bicycle or a walkway structure of JP 10-1118120 and a construction method thereof are disclosed.

The bicycle or sidewalk structure and method of constructing the same include a structure that is installed on a side surface of an existing bridge to extend a road, wherein a surface coupled to both ends of a coping portion of a pier is pierced to fit the shape of both ends of the coping portion A bracket that is coupled to an outer surface of the base opposite to the base surface of which one end is coupled with the coping portion; And a connecting member whose both ends are fixed to the fixing plate provided at both ends of the coping portion; An I-type girder which is connected to the upper surface of the bracket of the existing bridge piers installed at the lower ends of the existing bridge piers and which is installed along the direction of the existing bridge, and an I-type girder which has one end joined to the upper end of one side of the girder, And the other end of the auxiliary cross member is coupled to one side of the side surface of the girder and the other end of the auxiliary cross member is connected to the other side of the side surface of the girder and the cross member, An auxiliary girder having the same shape as the auxiliary girder, a wrapping plate provided on the surface formed by the girder, the auxiliary girder and the cross member, and the auxiliary cross member, and a rail structure provided on one side of the upper surface of the auxiliary girder in accordance with the direction of the existing bridge And an upper portion.

However, according to the conventional technique, the cross member is connected between the I-shaped girder installed along the longitudinal direction of the existing bridge and the girder, and as the time passes, the packing plate is twisted by the load applied to the bridge, There is a problem that the durability of the bridge structure is remarkably deteriorated.

Even if a structure for reinforcing the side surface of the bridge is not provided or a side reinforcing structure is provided, there is a problem that the structural rigidity is weak as a whole, so that a reliable wooden deck bridge structure can not be realized.
