法の１つの問題点になっている。It is common practice to rigidly connect a precast concrete beam to a concrete column by introducing prestress, but in the conventional method, even if the concrete column is ready-made or cast-in-place, a sheath is buried within the concrete column and It is necessary to connect this sheath to the sheath inside the precast concrete beam to prevent concrete from entering. However, it is difficult to reliably set and connect the sheath at joints where reinforcing bars, separators, spacers, etc. are involved, and this is one problem with the conventional method.

ある。The present invention aims to provide a method for joining precast concrete beams and columns that will solve the above problems and shorten the construction period of the entire building, and its structural features are as follows:
Place the end of the precast concrete beam on the bracket attached to the steel column, temporarily secure the precast concrete beam to prevent it from falling over, and attach the steel column to the end of the PC steel material inserted through the sheath inside the precast concrete beam. Connect the ends of the unbonded steel materials that pass through, and in this state, cast column concrete together with the floor concrete. After the column concrete has hardened to the specified strength, tension the unbonded steel materials and fix the ends to the column concrete. At the point.
以下、図示の一実施態様に基いて本発明を具体的に説明
する。Hereinafter, the present invention will be specifically explained based on one embodiment shown in the drawings.
図において、１はブレキャストコンクリート梁（以下、
ＰＣ梁という）であシ、その内部には複数本のシース２
が埋設され、その各々にＰＣ鋼材３が挿入されている。In the figure, 1 is a precast concrete beam (hereinafter referred to as
It is called a PC beam), and inside it there are multiple sheaths 2.
are buried, and a PC steel material 3 is inserted into each of them.
また、ＰＣＣ１０端には、下縁と上縁近くにそれぞれ短
いＴ形材４，５が基部をコンクリートに埋込んで取付け
られている。Further, short T-shaped members 4 and 5 are attached to the end of the PCC 10 near the lower edge and upper edge, respectively, with their bases embedded in concrete.
一方、図示の鉄骨柱６は、断面がＨ形（又は十字形、箱
形）で、その内側フランジ７の表面にはブラケット８が
取付けられている。On the other hand, the illustrated steel column 6 has an H-shaped (or cross-shaped, box-shaped) cross section, and a bracket 8 is attached to the surface of its inner flange 7.
本発明では、先ず、ＰＣＣ１０端部を鉄骨柱６のブラケ
ット８上に載置し、Ｔ形材４の露出部をブラケット８に
固着するとともに、Ｔ形材５の露出部を、Ｔ形材９を介
して鉄骨柱６の内側フランジ７に固着する。In the present invention, first, the end of the PCC 10 is placed on the bracket 8 of the steel column 6, the exposed part of the T-shaped member 4 is fixed to the bracket 8, and the exposed part of the T-shaped member 5 is fixed to the T-shaped member 9. It is fixed to the inner flange 7 of the steel column 6 via.

材３の端に接続する。By applying pressure in this way, the PC beam l is temporarily fixed to the steel column 6 in a stable state without falling over, and at the position M opposite to the exposed end of each PC steel member 3, the outer flange 10 and inner flange 7 of the steel column 6 are connected from the outside. Unbonded steel material 11
is inserted, and its tip is connected to the end of the PC steel material 3 via the coupler 12.
この状態で、床コンクリートと柱コンクリートの型枠組
立てや配筋等を行って、床コンクリート１３と柱コンク
リート１４ｆ、打設する。In this state, formwork assembly and reinforcement for the floor concrete and column concrete are performed, and the floor concrete 13 and column concrete 14f are poured.

ンボンド鋼材１１を緊張し、その端部を、適宜の定着具
１５を介して柱コンク’Ｊ −） １４に定着する。After the column concrete IJ-) 14 is hardened to a predetermined strength, the unbonded steel material 11 is tensioned and its end portion is fixed to the column concrete 'J-) 14 via an appropriate fixing device 15.
図示の場合は、ＰＣ鋼材３はＰＣＣ１０製作段階で緊張
されており、シース３にはすでにグラウトが施されてい
るが、無緊張状態のＰＣ＠材３にアンボンド鋼材１１を
接続し、アンボンド鋼材１１の緊張によりＰＣ鋼材３を
も緊張させる場合は、後でシース３内にグラウトを注入
することになる。In the illustrated case, the PC steel material 3 is tensioned at the PCC 10 manufacturing stage, and the sheath 3 has already been grouted. If the PC steel material 3 is also to be tensed by this tension, grout will be injected into the sheath 3 later.
本発明の接合方法は前述のようなものであり、その利点
としては次のような事項が挙げられる。The joining method of the present invention is as described above, and its advantages include the following.
柱部分のＰＣ鋼材にアンボンド鋼材を用いたことにより
、この部分にシースを配設する必要がないから、先に述
べた従来法に比べて接合部の作業性が良好であり、施工
の確実性も大である。By using unbonded steel for the PC steel in the column, there is no need to install a sheath in this area, so the workability of the joint is better than with the conventional method mentioned earlier, and the construction is more reliable. is also large.
ＰＣ梁の端部を鉄骨柱に転倒しないように仮止めした状
態で床コンクリートと柱コンクリートを打設するので、
全体的工期の短縮が期待できる。Floor concrete and column concrete are poured with the ends of the PC beams temporarily secured to the steel columns to prevent them from falling over.
It is expected that the overall construction period will be shortened.
アンボンド鋼材の使用によシ、接合部にしん性が付与さ
れ、耐震上好ましい剛接合部が得られる。The use of unbonded steel imparts stiffness to the joint, resulting in a rigid joint that is favorable for earthquake resistance.
