Abstract

PURPOSE:To save a construction cost hy stretching the respective lower chords of truss bodies, to push frames consisting of trusses, upward in the shape of an arch, and by arranging the tie rods of the lower chords between the lower chord end sections of the trusses. CONSTITUTION:Sections between the end sections of the upper chords 1a of trusses 1 adjacent to each other are jointed to each other with pins 2 to connect the respective trusses 1 to each other, and the one end of a truss group is pin- supported 3, and the other end is roller-supported 4, and the intermediate section is temporarily supported by a temporary bearing member. After that, between the end sections of the lower chords 1b of the trusses 1, stretching jacks 7 are placed, and the jacks 7 are connected to a control body 9 via hydraulic hoses 8, and at the support 4, a horizontally pushing jack 10 is set. After that, the jacks 7 are worked, and spaces between the lower chords 1b are shortened, and the whole frames are pushed upward. Besides, when the frames are raised in the shape of a specified arch, then tie rods are connected to sections between the end sections of the lower chords 1b, and after that, the jacks 7 are removed from.
