The present invention relates to a horizontal member system using a structure between long spans, which comprises an assembly type precast concrete member, and a depositing part. The assembly type precast concrete member comprises: a bottom flange having a constant-shaped section, in which a plurality of first penetration holes is formed to be separated at regular distance intervals in a transverse direction vertically with regard to a longitudinal direction; and/or a abdomen formed on the bottom flange when the bottom flange is formed, and having a constant-shaped section, in which a plurality of second penetration holes is formed to be separated at regular distance intervals in a transverse direction vertically with regard to a longitudinal direction; and a top flange coupled on the bottom flange or the abdomen, and having a constant-shaped section, in which a plurality of third penetration holes is formed to be separated at regular distance intervals in a transverse direction vertically with regard to a longitudinal direction, and the depositing part being formed by depositing a topping concrete on the assembly type precast concrete member. The bottom flange, the abdomen and the top flange of the assembly type precast concrete member are separately manufactured using a precast concrete method, the first, second and third penetrating holes of the assembly type precast concrete member is formed in an area of corresponding with each other to be seen as one hole when viewed from above at the time of coupling the top and bottom flanges and the abdomen of the assembly type precast concrete member. Moreover, after a bolt is inserted by penetrating in the top and bottom flanges and the bottom flange and the first, second and third penetrating holes in the abdomen, and is fixed with a nut, the abdomen and the top flange are pressing-coupled to one another. |
