PROBLEM TO BE SOLVED: To provide a construction form for constructing an expansion joint capable of coping with the replacement of only a form construction panel even when the size of a rail joint opening is different between a bridge girders or between the bridge girder and an abutment. SOLUTION: The form construction panel 12 and an end part reinforcing plate 14 adapted to a width of the rail joint opening, are installed in a form body 11 by using an installation member 13. A position of the installation member 13 is adjusted in response to a width of the form construction panel 12, and a position of the end part reinforcing plate 14 is adjusted. The form construction panel 12 is removed from the form body 11, and the construction form body 11 is positioned in a box extracting part arranged in a floor slab end part. The form body 11 and the end part reinforcing plate 14 are fixed to an embedded reinforcement anchor embedded in a floor slab. The form construction panel 12 is installed again in the form body 11. Post-placement concrete is poured into an area surrounded by the form body 11, the form construction panel 12, the end part reinforcing plate 14 and the floor slab. After curing the post-placement concrete, the form body 11 and the form construction panel 12 are removed. COPYRIGHT: (C)2007,JPO&INPIT
