PROBLEM TO BE SOLVED: To shrink a beam framing as a receiving girder, to miniaturize the whole structure on the ensuring of the same inner section and to quicken the execution of works and reduce a cost by combining an assembled truss frame as a reinforced frame. SOLUTION: A timbering construction method has a plurality of lower chords 12, in which both ends are installed on the upper sections of a pair of side walls 3 at regular intervals and which are composed of H-steel, a plurality of deck plates 14, in which both ends are mounted on the lower flanges of each lower chord 12 and which cover the upper (top-slab undersides) openings of the side walls, and the truss frames 16 being integrally assembled to the upper sections of each lower chord 12 and constituting the receiving girders together with the lower chords 12. Lower reinforcing bars 18 are arranged on the lower chords 12, the truss frames 16 are assembled to the lower chords 12, top-slab upper reinforcing bars 20 are arranged to the upper sections of the truss frames 16, using the truss frames 16 as the reinforced frames, and top slabs 22 are built by placing concrete.
