ERECTION METHOD AND DEVICE FOR STEEL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an erection method and device for a steel structure shortening a construction period, reducing an erection cost and improving safety in constructing the steel structure such as a station terminal building at an upper part of an existing facility such as a platform of an existing station. SOLUTION: All permanent first section columns a1of the steel structure are erected, and blocks of suitable length of an upper structure AUare assembled on a permanent end frame 1 constructed on one end side. The assembled blocks are slid to the other end side, and the following blocks are assembled and connected to the slid blocks. This process is sequentially repeated to slide the upper structure AUprojected to the other end side from the end frame 1, while supporting it by the first section columns a1on the other end side. When the upper structure AUreaches a prescribed installation position, the upper structure AUis lowered to connect second section columns a2of the upper structure AUto the first section columns a1, and first section floor slabs b1are lowered into the regular mounting position and joined to the first section columns a1.
