PROBLEM TO BE SOLVED: To mount horizontal pipelines of a facility including air conditioning and hygiene pipelines and frame materials as a unit when steel materials of a building are constructed.SOLUTION: In a horizontal pipeline unit construction method, a horizontal pipeline unit in which horizontal pipelines of a facility including air conditioning and hygiene pipelines and frame materials are unitized is incorporated. After a plurality of girders A, C of a building are combined and before beams are combined between the girders A, a horizontal pipeline unit 1 is hangingly hoisted above the girders A, C at the outside of the building and the horizontal pipeline unit 1 is moved into the inside of the building and is hung down below the girders A, C. Then, the frame materials and the girders C are joined together while the horizontal pipeline unit 1 is positioned substantially in parallel with the girders A. |
