If a sheath (not shown) is embedded also in the portion (between), the PC steel material 5 is pushed into the inside of one beam 1, and after the beams 1 and 1 are erected, the PC steel material 5 can be inserted. It is easy, and the tension of the PC steel material 5 can be performed using a small jack having a size that fits in the vertical hole 3.
【００１１】なお、梁１を柱２の一側のみに接続する場
合は、ＰＣ鋼材５の一端は柱２の側面に定着することに
なる。When the beam 1 is connected to only one side of the pillar 2, one end of the PC steel material 5 is fixed to the side surface of the pillar 2.

工能率が良好で工期を短縮できる。Since the present invention is as described above,
The following effects can be expected. As in the case of the prior art described above, the precast beam can be fastened to the column by the PC steel material without increasing the cross section of the end portion of the beam. Since the PC steel material is tensioned and fixed in the vertical hole that opens at the top of the beam,
Tensioning and fixing work of PC steel is easier than when the opening is sideways. Since the filling of mortar or concrete for filling holes can be performed without a formwork and by dropping from above, the filling operation is easier and easier than when the openings are oriented horizontally. Overall construction efficiency is good and the construction period can be shortened.
