Abstract

PURPOSE:To enable a bolt to be stably fastened in a place having a limited space and located in the elevated level of a stay, by a method wherein, in a monorail construction site, a fixing bolt mated to a coupling rod is coupled directly to a foundation bolt, the coupling rod is pushed upward by means of a pair of hydraulic jacks, and torque is managed by means of an oil pressure gauge. CONSTITUTION:A beam 11 is temporarily placed so that the bolt holes of a lower support 5 of the beam 11 are engaged with four foundation bolts 2. A regular nut 7 is threadedly joined with the foundation bolt 2 and rotated to a cam 3, and a fixing bolt 26 is inserted in a coupling rod 25 to threadedly joint it with the foundation bolt 2. The coupling rod 25 is raised to the support part of the fixing bolt 26, and is set such that the shaft of each of a pair of hydraulic jacks 24 is engaged with each of spherically dented shaft supports in both ends of the coupling rod 25. By connecting the hydraulic jack 24 with a hydraulic pump 21 having an oil pressure gauge 22 through a hydraulic hose system 23, the hydraulic pump 21 and the hydraulic jack 24 can be moved in a position allowing a worker to execute a safe and reliable work.
