  As shown in FIG. 13, the reinforced concrete column 4 has a main bar 43 extending in the height direction Y inside the reinforced concrete column 4 by connecting a plurality of reinforcing bars 41 in the height direction Y by a connecting portion 42 by a lap joint or the like. It arrange | positions at several places and the connection part 42 will be arrange | positioned to the side of the beam steel beam 3. Note that the reinforced concrete column 4 includes a beam-to-column joint 40 in which the coupling portion 42 is disposed, and the coupling portion 42 among the plurality of column-beam joints 40 to which the inter-beam steel beam 2 and the girder steel beam 3 are joined. And the column-beam joint portion 40 that is not disposed.

  The reinforced concrete column 4 is attached with a face bearing plate 24 such as a pair of steel plates so as to cover a groove formed by the upper flange 21, the lower flange 22 and the web 23 of the inter-beam steel beam 2. Concrete can be placed while making a part of the formwork. At this time, the reinforced concrete column 4 does not require a separate formwork formed in an uneven shape along the groove portion of the inter-beam steel beam 2, and concrete can be easily placed to form a reinforced concrete column. It can be built.

  As shown in FIG. 7, the columnar beam structure 1 of the plate-like apartment house to which the present invention is applied is such that the inter-beam steel beam 2 is arranged on the upper part of the lower floor Fd, so that the passage C of the common part S becomes the inter-beam steel beam 2 and without forming a step due to the inter-beam steel beam 2 at the foot of the passage C, the inter-beam steel beam 2 is connected to the reinforced concrete columns 4 arranged in pairs facing the inter-beam direction Z. It can be extended.

  In the columnar beam structure 1 of a plate-like apartment house to which the present invention is applied, a girder steel beam 3 arranged at the lower part of the upper floor Fu is provided above the inter-beam steel beam 2 arranged at the upper part of the lower floor Fd. Thus, the girder steel beam 3 is not provided as a hanging wall from the upper part of each floor, and the walls such as the handrail wall of the balcony B of the common part S and the handrail wall of the passage C without obstructing the view of the owner of the dwelling unit etc. A girder steel beam 3 can be provided inside the body 80.

  On the other hand, as shown in FIG. 14, the conventional column beam structure 9 is provided with a concrete bearing wall 91 on the boundary wall D without providing a steel beam as a structural member extending in the inter-beam direction Z. There are no openings in the load bearing wall 91 for securing the passage C of the shared part S up to the part where the load bearing wall 91 is joined to the reinforced concrete column 90. The pillar 90 had to be arranged.

  Further, in the conventional column beam structure 9, a reinforced concrete beam 92 extending in the row direction X is arranged at the upper part of each floor without providing a steel beam as a structural member extending in the column direction X, and the reinforced concrete column 90 is provided with the reinforced concrete beam 92. Since they are to be joined, the reinforced concrete beam 92 is provided like a hanging wall from above each floor.

  For this reason, in the conventional column beam structure 9, when the reinforced concrete columns 90 are arranged at the four corners of the exclusive portion P, the opening A for entering and exiting the balcony B and the entrance E for entering and exiting from the passage C are provided. Since the reinforced concrete beam 92 is partially blocked from above, it is necessary to increase the floor height H of each floor in order to secure a predetermined opening height at the opening A and the entrance E.

  Further, in the conventional column beam structure 9, even if the reinforced concrete column 90 is provided on the balcony B or the passage C of the common part S, the reinforced concrete beam 92 joined to the reinforced concrete column 90 is provided from above each floor. By being provided like a hanging wall, it obstructs the field of view of owners such as dwelling units, and it has been necessary to increase the floor height H of each floor in order to ensure a predetermined field of view.

  As shown in FIG. 7, the column beam structure 1 of the plate-like apartment house to which the present invention is applied is provided in the common part S, without the girder steel beam 3 extending in the girder direction X being provided in the exclusive part P.
