が容易になる。(Effects of the Invention) According to the present invention, as described above, the PC beam does not need to be composed of a single member of the cross-shaped girder.
By preparing a total of four PC beam members, one pair each in length and width, with a beam main bar protruding from one end face opposite to the intersection of the cross-shaped PC beams and a notched step at the other end. Therefore, after constructing the columns and girders, each of the PC beam members can be easily carried into the space surrounded by the girders. In addition, by mounting the cutout step provided at the other end of each PC small beam member on the cutout step for the small beam receiver provided in the main beam, each of the PC
The other end of the small beam member is supported by the large beam, and each
Since post-cast concrete is placed at the intersection of the PC beam members, it is only necessary to provide shoring to temporarily support the intersection, and the shoring is simpler than when using large cross-shaped members. Moreover, the installation of the PC beam members is facilitated because the lifting equipment used for erection of the columns and girders is used as is.
