Bridges generally refer to facilities provided to allow vehicles or people to cross terrain with severe elevations such as rivers and valleys, and are installed in various ways depending on the characteristics and purpose of the site to be constructed.

In the case of a bridge provided for the main purpose of moving vehicles, additional installation of sidewalks or bicycle paths may be required depending on the development of the surrounding area and if necessary. To solve this problem, an extended footbridge is installed. After installing poles or piles at regular intervals, the girders are fastened on the poles and the floor is formed directly on the top of the girders, or a cantilever is installed to form the floor on the top.

The coupling between the first support plate 330 , the auxiliary bar 360 , and the second support plate 350 is a vertex of the coupling portion between the auxiliary bar 360 and the second support plate 350 . It may be combined to form an isosceles triangle with Therefore, by dispersing and supporting the load applied to the first support plate 330 and the second support plate 350 by the auxiliary bar 360, the support force of the support member 300 for the deck member 100 can be reinforced. have.

In this case, the stiffness of the auxiliary bar 360 may be formed to be weaker than that of the second support plate 350 and the first support plate 330 . For example, the auxiliary bar 360 may be provided to have a relatively weak rigidity by being formed of a metal having a thickness or width smaller than that of the second support plate 350 and the first support plate 330 , or of a different material. Therefore, when strong vibration acts on the support member 300 , the auxiliary bar 360 absorbs the strong vibration due to deformation such as cracking, thereby helping to alleviate the impact applied to the support member 300 .

Furthermore, the base part 310 has a bracket 311 on the lower side, and one end of the second support plate 350 is fitted between the brackets 311, the bracket 311 and the second The fifth vibration reducing part 450 may be positioned between one end of the support plate 350 . Of course, as shown in FIG. 5 , a bracket may be provided in the coupling region with the H-beam 320 of the second support plate 350 , and it is obvious that the fifth vibration reducing unit may be located.

The fifth vibration reducing unit 450 may be provided in a plate shape in which an elastic layer 453 is interposed between the support plates 451 , and the elastic layer 453 is formed in a stacked structure of elastic plates having different elastic forces. can be As shown in FIG. 5 , a fifth vibration reducing part 450 may be interposed in a structure in which the support plate 451 is in contact between both sides of one end of the second support plate 350 and the bracket 311 , The bracket 311, the fifth vibration reducing part 450, and the second support plate 350 can be coupled through the 311B.
