本发明提供一种方法，桥梁施工用于安装多路径之间的桥梁的跨部件的梁100，通气过度，其中值梁100假设的跨度（A）区域，跨度安装假想事件300的安装步骤 移动轨道安装步骤，在底板1的与区域A相邻的一侧的上表面上安装移动轨道200以用于观察主梁100， 安装haneungeo进一步安装步骤中，所述一个底板（1）用于安装牵引装置400，以驱动所述梁（100），所述牵引装置400的牵引装置安装步骤，涡住宅更多的相对的（ 100通过驱动牵引装置400移动桁架100以将牵引构件410连接到保持装置410而安装在跨度A的跨度的两端 ）通过haneungeo更多安装步骤中，假说除去假说通风口300的通气口去除步骤和gyojwa梁（100），以增加驱动以降低安装装置500到 该装置还包括使用移动导轨安装桥梁的梁的第三步骤。 根据本发明，使用所述移动导轨和牵引装置，一个连续梁桥式起重机的一部分构造的方法不可用时，可以在不昂贵的设备假设来构造。 另外，由于施工时间短，施工时间可以缩短，移动的钢轨可以适用于所有场地，而不考虑桥梁的长度和尺寸。

The present invention provides a method bridge construction for installing the girder 100 of the part-span of the bridge between the multi-path, vent installation step of installing a hypothetical event 300 over the span (A) region in which the girder 100 is installed, the span (a) on the upper surface of one side of the bottom plate (1) adjacent to the area moving rail installation step of installing the movable rail (200) for the traction of the girder 100, and the girder (100) to the movable rail (200) mounted girder-mounted step, towing unit installation steps for installing the traction device 400 to drive the said girder (100) opposite to the one side the bottom plate (1), the traction device 400 and the girder ( 100) pulling member 410 traction element installation phase, through the device to drive the traction device 400 is installed to the girder 100 on both the pedestal section (2) of the span (a) region (500 to connect to ) girder through two steps, the hypothesis vent removal step and the mounting device (500 removing the hypothesis vent 300. mounted on) Present a method of traction girder bridge construction using the mobile rail comprising a; driven to lower the height of the girder mounted to mount the girder 100 to the device gyojwa Step 3.
According to the invention a method of construction using the moving rail and the traction device, a portion of a continuous girder bridge crane is not available, it can be constructed without expensive equipment hypothesis.
In addition, because of the short construction time, it is possible to minimize the construction period, the movable rail is applicable to any field, regardless of the length and size of the bridges.
