PURPOSE:To reduce the construction term and the cost by mounting a tensioner member on a bracket fixed on a suspended structural member, installing a hangup means on a bracket fixed to supporting structure, and pulling up the tensioner member by this hangup means. CONSTITUTION:A chord tensioning beam 3 is assembled on a provisional mount table installed on the ground between supporting structures. Tensioner members 5 are fixed to the ends of this chord tensioning beam 3, and the upper part of each tensioner member 5 is mounted on a hangup jack 6 installed over the inner end of a receipt truss 2 on each structure 1 and lifted. A provisional plate is fixed to each joining end of the receipt truss 2 and chord tensioning beam 3, and provisional plates are joined with each other by bolt provisionally. After the jack 6 is removed, the receipt truss 2 and chord tensioning beam 3 are joined permanently.
