PROBLEM TO BE SOLVED: To provide a small light weight jig which carries out the temporarily locking work of a splice plate to the web of a H steel frame effectively easily with relatively small force. SOLUTION: The jig 1 for temporary locking is provided with a fitting part 2 which is fitted to the head of a bolt B, a first rod part 3 which extends along the plate surface of the splice plate 24 from the fitting part 2, a pressing part 4 which extends at a right angle to the splice plate 24 side from the end of the first rod part 3 and is brought into contact with an upper short side 24c, and a second rod part 5 which extends in the direction opposite to the first rod part 3 from the pressing part 4. The splice plate 24 is upwardly rotated by pressing downward and rotating the end of the second rod part 5 in a state that the pressing part 4 is brought into contact with the upper short side 24c of the splice plate 24. The temporarily fastening work is carried out by screwing a nut to a bolt B in a state that the splice plate 24 is positioned in a temporarily locking state. COPYRIGHT: (C)2007,JPO&INPIT
