PURPOSE: To summarize conventional constructing method and enhance the industrializing ratio of constructed beams.
CONSTITUTION: A beam constructing structure is formed of large beams 2, 2 erected between columns 1, 1 and opposed to each other, and a pair of small beams 4, 4 erected at a determined interval between them to be parallel to each other. Of the whole large beam 2, the erecting part of the small beams 4, 4 is formed of a conventional part 7, and the remaining part is of a half PC part 8. The large beam 2 half-precasted with leaving the part forming the conventional part 7 in a part of its own body is erected between the columns 1, 1. The pair of small beams 4, 4 are erected at a determined interval between respective opening parts of the opposed large beams 2, 2 to be parallel to each other. Then, molds 14 are arranged in the opening part of each large beam 2, 2 and between the pair of small beams 4, 4, and concrete is placed therein.
