期待できる。As described above, according to the present invention, the concrete of the beam-column crossing portion is cut away, only the column main bar is exposed at the crossing section, and the reinforcing hoop reinforcement is provided on the column main bar. Since we made hollow precast concrete columns that were attached in a bundle, the number of members was reduced,
Productivity in manufacturing, transportation, and assembly of members will be improved, and the number of joints of the main bars will be reduced, which can be expected to improve economic efficiency.

る。Further, since the adjacent precast concrete columns are provided with a level difference of one layer, the precast concrete girders can be easily assembled.
Furthermore, since the cross section of the precast concrete column is hollow, the weight of the member is reduced, and the economical efficiency of manufacturing, transporting and assembling is improved. Furthermore, by utilizing the hollow portion of the precast concrete column, it becomes possible to set the fixing method of the end-defining main bar of the girder downward.
