BRIDGE FLOOR SLAB DECOMPOSITION DEVICE AND BRIDGE FLOOR SLAB DECOMPOSITION METHOD

摘要

To provide a bridge floor slab decomposition device and a bridge floor slab decomposition method which makes it possible to further improve the installation property and economical efficiency.SOLUTION: It is provided with reciprocation driving means 2 for making a device body 1 reciprocate in a back-and-forth direction T1; and first cutting means 8 which is attached to the device body 1 and cuts a floor slab 3 immediately above an upper flange of a steel girder 4, and a stud implanted in the upper flange along with the movement the device body 1 in a lateral width direction and along a bridge axial direction. Furthermore, second cutting means 5 is provided which is attached to the device body 1 and cuts both the right and left sides of the floor slab 3 across the steel girder 4 along the bridge axial direction along with the movement of the device body 1.SELECTED DRAWING: Figure 1
