Description of the Related Art In a joint structure of a reinforced concrete column and a steel beam in a structure composed of a reinforced concrete column and a steel beam, how to construct the joint portion between the column and the beam to ensure reliable transmission of the load between them. It is a technical problem. In order to transfer the shearing force and bending moment from the steel beam to the reinforced concrete column, the beam member is penetrated into the column, the joint is surrounded by a steel plate outer frame, such as a steel pipe, and a horizontal bearing plate is installed inside. Methods such as providing or welding and fixing a reinforcing bar to a steel beam have been used.

点がある。For example, FIG. 5 is described in "Construction Technology", August 1990, "Development of Mixed Structure and its Background", page 118, in which the girder 2 penetrates this joint and is continuous left and right. The main reinforcing bar 11 is a screw reinforcing bar and is fastened by the flange surface fixing nut 36 of the girder 2. On the other hand, a reinforcing iron plate (blocking plate) 3 is wound around the pillar portion of the joint portion, and also serves as a concrete formwork to constrain the concrete inside to form a strong joint portion. However, this structure is not only very uneconomical in that the construction is complicated and requires a lot of labor, costs are high, and it takes a long time to complete the construction. However, there is a problem in that the load transmission is disturbed.

ている。Example 1 FIG. 1 shows a first example of the present invention. (A) is a side view of a state in which some concrete is cut to expose the reinforcing bars,
(B) is the AA sectional view. Reference numeral 1 is a reinforced concrete column, 2 and 2'are steel beams, and the reinforced concrete column 1 is composed of main reinforcing bars 11, hoop reinforcing bars 12, and concrete 13. The steel beams 2 and 2 ′ are made of H-shaped steel having upper and lower flange surfaces, and the respective tip portions are immersed in the reinforced concrete column 1 by a length a. Steel beams 2 and 2'are connecting members 21
Are pierced through the reinforced concrete columns 1 and connected to each other. That is, the connecting member 21 is composed of two steel plates having vertical projections on the surface thereof, and is joined to the web portions of the steel beams 2 and 2 ′ by the high-strength bolt 22. Steel beams 2, 2 '
The front end portion of is locked and supported by a locking metal member 35 that is temporarily fixed to the main rebars 11 opposed to each other by welding or the like.

であり、構造物の設計上の荷重支持ではない。The steel beam web portion and the connecting member 21 may be joined by direct welding instead of high-strength bolts. Further, instead of welding the locking metal 35 to the main reinforcing bar 11, the hoop reinforcing bar closest to the flange of the steel frame beam may be brought close to this flange and welded to the main reinforcing bar to support the steel beam. The support of the steel beams 2 and 2'by the locks 35 and the like is temporary support until concrete placement in the building stage, and is not load support in designing the structure.

This protrusion may be provided by welding or the like, and a steel plate with a protrusion or a striped steel plate may be used as a material. Particularly when importance is attached to horizontal load transfer in this portion, it is more preferable to provide a vertical protrusion as illustrated.

ンクリートを充填することができる。After the reinforcing bars and the steel beams are constructed as described above,
Although the formwork is assembled and the concrete 13 is placed to construct the skeleton of this structure, according to the present invention, the steel beam 2, 2'is locked to the main rebar 11 by the locking metal 35. Therefore, for example, as shown in FIG. 2, it is possible to raise the main reinforcing bar to the upper floor and to attach the steel beam regardless of the concrete placement of the pillar portion. Since 21 penetrates the inside of the reinforced concrete pillar 1 and connects with each other, and the longitudinal projection is provided on the surface of the connecting member 21, the steel beam and the concrete are attached and integrated, and Since the tip is immersed inside the reinforced concrete column 1, horizontal and vertical loads from the beam are surely transmitted to the reinforced concrete column, and even in the joint where the beam and the column intersect, the beam is distributed over the distance d in the central part. Vertical and suspended Coupling member 21 is no hindrance to pouring of the concrete because it is only exist, it is possible to fill the most important reliably concrete to steel beam flange lower portion or the like in load transmission.

From the workability of (1), a dimension of b is required to some extent, so it may be determined in consideration of both of them. Further, in this embodiment, the simplest case is shown in which the beams are provided only in the left and right directions with respect to the columns, but columns having beams in three directions, four directions, etc. are rather common.

(A) is a side view of a state in which a part of concrete is cut to expose a reinforcing bar, and (b) is a BB sectional view thereof. Reinforced concrete columns 1, steel beams 2, 2 ', main rebars 11, hoops 12, and concrete 13 are all the same as in the first embodiment and FIG. The difference lies in the joint portion, and in this embodiment, the frame body 3 made of steel plate and having substantially the same outer shape as the reinforced concrete column 1.
Are arranged, and the tip portions of the steel beams 2 and 2 ′ are joined to the frame body 3 by welding. The frame body 3 is formed inside the outer frame 31 by providing a partition plate 32 on the extension surface of the web of the steel beam 2, 2 '.

仕切り板32を平行に２枚以上設ければよい。In this embodiment, the frame 3 is fixed around the reinforced concrete column 1 and the tip of the steel frame beam is joined to the frame 3 so that the horizontal force is transmitted from the steel beam to the column. However, since it is considered that the frame 3 alone is insufficient for transmission of vertical force or moment, the partition plate 32 is provided inside to increase the adhesive area with concrete and the inside of the outer frame 31. Alternatively, instead of keeping the surface of the partition plate 32 flat, a striped steel plate or the like is used to provide protrusions on the surface. In particular, in order to emphasize load transfer in the vertical direction, in the example of FIG. 3, a steel plate with projections is used as the material of the partition plate 32, and horizontal projections are provided on both sides. If it is desired to further increase the adhesive area, two or more internal partition plates 32 may be provided in parallel.

The frame body 3 is locked to and supported by the main rebars 11 via the clasp 35, and the same effect as described with reference to FIG. 2 in the first embodiment is obtained. The shape of the locking metal 35 is not limited to that shown in FIGS.
Various modes are possible, such as connecting 5'to form an integral body, or locking a horizontal projection instead of supporting the bottom side of the frame body 3.
