され、この結果複合梁７（第２図）が形成される。In FIGS. 1 to 3, a 20 member 1 is used as a core material of a beam in this example, and reinforcing bars 2, 2 are arranged in the longitudinal direction at the top and bottom of the inside. Both reinforcing bars 2. In 2, both ends of a plurality of reinforcing bars 3 arranged at regular intervals are looped. There are 26 members 10 between the pitches of each reinforcing bar.
A through hole 4 passing through in the width direction is provided. Each through hole 4... is for enhancing the restraint between the PC member l and the post-cast concrete, and this through hole can also be used as an equipment hole for an equipment sleeve or as an insertion hole for a separator. It is possible. Also, main beam reinforcements 5 are arranged on the outside of the 20 members 1, and stirrups 6 are hung around the main beam reinforcements. PC member l is beam main reinforcement 5
．． The stirrup 6 and post-cast concrete are integrated, and as a result, a composite beam 7 (FIG. 2) is formed.

継手パイプ８，１０との結合を固定している。Further, the rear end of a joint pipe 8 is crimped to the end of the reinforcing bar 2 of the 26 member 1, as shown in FIG. This joint pipe protrudes outward from the end surface of the 20 member 1, and is provided with a screw thread 8a inside. The joint pipe 8 has a threaded rod 11 attached to a joint pipe 10 that projects horizontally from the outer surface of the steel column 9.
Can be connected by The joint pipe 10 is provided with a female thread 10a inside, and its rear end is fixed to the outer surface of the flange of the steel column 9 by welding. One end of the threaded rod 11 is screwed to the joint pipe 8, and the other end is screwed to the joint pipe 10 on the steel column side, thereby joining the 26 member 1 to the steel column 9. Nuts 12 and 13 attached to the threaded rod 11 fix the connection between the threaded rod 11 and the coupling pipes 8 and 10.
ここでネジ棒１１による継手パイプ８と１０の連結操作
について説明する。Here, the operation of connecting the joint pipes 8 and 10 using the threaded rod 11 will be explained.
