PURPOSE: A cross connecting box girder of a pre-cast concrete hollow slab type and a bridge constructing method using the same are provided to enable easy, efficient and safe work without a separate working table since a cross distribution structure is made on a girder. CONSTITUTION: A cross connecting box girder of a pre-cast concrete hollow slab type is as follows. An L-shaped connecting unit is formed on the top(110) of a girder. The L-shaped connecting unit comprises a vertical unit(114) and a horizontal unit. The vertical unit is formed downwardly from the top. The horizontal unit is formed horizontally from the side(120). The horizontal rebars(114a) of the top of the vertical unit are horizontally exposed at regular intervals. An anchor bolt(116a) is buried at the horizontal unit and is exposed from the top. The anchor bolt corresponds to the fastening hole(142) of a connecting steel sheet(140) with the same length to the gap of the horizontal rebars. |
