Method of replacing PC floor slabs using temporary floor slabs

Abstract

To provide a PC floor slab replacing method using a temporary floor slab for shortening a construction period in replacing work to a new PC floor slab.SOLUTION: A PC floor slab replacement method using a temporary floor slab 1 is a method for replacing an existing concrete floor slab 32 of a steel girder bridge with a new PC floor slab 35 using a plurality of temporary floor slabs 1. An existing floor slab removing step S11 of removing an existing concrete floor slab 32 on an existing steel girder, a temporary floor slab installation step S13 of installing a temporary steel floor slab 1 on the existing steel girder as a temporary steel floor slab 1 using a crane 2, and installing a new PC floor slab 3 on the existing steel girder from one end of the existing steel girder to an other end side hoisting position where the new PC floor slab 3 can be hoisted from above, a new PC floor slab installation step S14 of removing the other temporary floor slab 1 from the other end side hoisting position to the one end, and installing the new PC floor slab 3 on the existing steel girder; The present invention is characterized by comprising: SELECTED DRAWING: Figure 3
