    • 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.
    • 目的:提供一种预制混凝土空心板型的交叉连接箱梁和使用该预制混凝土空心板式桥梁的桥梁施工方法,由于在大梁上进行了交叉分配结构,因此无需单独的工作台即可实现简单,高效和安全的工作。 构成:预制混凝土空心板型交叉连接箱梁如下。 在梁的顶部(110)上形成L形连接单元。 L形连接单元包括垂直单元(114)和水平单元。 垂直单元从顶部向下形成。 水平单元从侧面(120)水平形成。 垂直单元顶部的水平钢筋(114a)以规则的间隔水平曝光。 锚定螺栓(116a)埋在水平单元处并从顶部露出。 锚定螺栓对应于与水平钢筋的间隙具有相同长度的连接钢板(140)的紧固孔(142)。
