段を含む。In the lower floor pillar made of precast concrete, similarly to the upper floor pillar, the column main bar connecting end projects from the column base end surface. In order to make it easier to place concrete at the joint between the column and the beam, a through hole is formed in the axial direction of the column from the end face of the column head to the end face of the column base, through which a filler such as concrete or mortar can pass. It is desirable to put it. At the same time, it is preferable to form the end face of the column base of the column into an inverted trapezoidal cross section having a tapered surface that is inclined downward toward the center. The through hole may be single or plural, and its cross-sectional shape does not matter. As the column joint member, for example, a mortar-filled metal sleeve material is used. Further, in the case of a plurality of beam main bars by multi-stage bar arrangement, the on-site beam joint means of the beam connects the beam main bar connecting ends of the beam main bars including the lower end bar. The field beam joint means includes a mechanical joint member such as a screw type, a filling type or a steel pipe crimping type, or various joint means for connecting the opposite beam connecting ends by welding, gas pressure welding means or lap joints.

図１２及び図１３に示された柱と同じである。14 and 15 show examples of different columns used in the same construction method as the embodiment of FIGS. 12 and 13. The column 201 has a tapered surface 218 on the end surface of the column base of the column body 202, which is inclined downward toward the center of the column body. As a result, the lower end of the column base has a substantially inverted trapezoidal cross section. Other configurations are
It is the same as the pillar shown in FIGS. 12 and 13.

て行われる。The tapered surface 218 forms an annular gap 219 between the bottom surface of the column base and the upper surface of the beam. Therefore, when concrete is poured into the joint through the through hole 217,
The gap 219 functions as an open window for visually recognizing the situation of the concrete pouring from the outside, and also functions as an air vent for the pouring concrete. Further, when the column and the beam 209 are joined by using the column 201, the mortar grouting work on the joint is unnecessary. It is desirable to use high flow rate concrete. Note that the pillar in which the lower end of the pillar base is formed in a substantially inverted trapezoidal cross section can be configured as a pillar having no through hole unlike the case of FIGS. 14 and 15. In this case, the step of filling the joint between the column and the beam with the filler is performed in the same manner as the column of the embodiment of FIG. 1 described above.

減化を図ることができる。As described above, according to the present invention, since the column main bar connecting end does not project to the column head forming the joint, they are opposed to each other on the flat column head end surface without obstacles. The main beam connecting end of the beam can be reliably joined by various on-site beam joint means. For this reason, the beam ends of the beams for each span are abutted in the horizontal direction in one direction, the T-direction, or the cross direction at the joints with the columns without manufacturing a complicated and large-sized beam structure as in the past. Thus, they can be easily joined. The joining in the L-shape can be performed more easily than in the conventional example. In addition, compared to the conventional method that uses a beam structure that joins beams at the mid-span of the beam, the number of joints between beams is reduced and the number of steps can be reduced accordingly, and the loader is also relatively small. The above can be used, and the construction cost can be reduced.

で、その分の手間や工程数も削減できる。According to the present invention, the beam for each span can be suspended and placed at the joint position, and the beam can be slid at the joint portion with the column not only vertically or axially but also in the beam width direction. Since they can be arranged, workability of beam joining can be improved. In addition, since no support work is required for beam joining, the labor and the number of steps can be reduced.

接合部に十分な耐力と剛性を確保できる。In the joint structure obtained by the method of the present invention, not only the upper end bar of the main beam of the beam due to the multi-stage bar arrangement but also the lower end bar of the beam is strengthened at the site by the joint means in the joint between the column and the beam. Since they are joined to each other, sufficient strength and rigidity can be secured at the joint between the column and the beam.

Because it is done
By increasing the cross-sectional area of the column main bar in the column main column supporting the beam, the strength can be reinforced.
