Precast concrete barrier and barrier system of bridge

The present invention relates to a precast barrier member and a bridge structure of a bridge using the same, and by making the precast barrier member constituting the barrier in advance before the construction of the bridge, the construction site uses a precast barrier member in a construction site for simple operation. An object of the present invention is to provide a barrier structure in which a barrier is integrated with a bridge deck when constructing a barrier using a precast barrier member and a precast barrier member configured to be completed. Precast security member of the present invention for achieving the above object is a reinforced concrete structure, a groove is formed in the longitudinal direction on the bottom surface, a portion of the reinforcement located therein is protruded into the groove, It is characterized in that the pour in communication with the outer surface of the structure is formed. In addition, according to the security barrier structure of the present invention, the precast security barrier member, a bridge bottom plate protruding a part of the reinforcing bar located inside the boundary line to be constructed, the reinforcement of the bridge bottom plate and the precast security barrier A reinforcing bar passing through the overlapped portions in a state where the rebars of the members cross each other, and a filler filled inside a groove of the precast security barrier member, wherein the plurality of precast security barrier members are disposed along the boundary line to form a security barrier. It is a technical feature to do.
