Abstract

PURPOSE:To facilitate construction work, by providing steel skeleton columns, a plurality of reinforcing rods extending along the steel skeleton column 4, steel pipe joints, concrete filled in the steel pipe joint, steel skeleton beams, and concrete covering the steel column. CONSTITUTION:A plurality of main reinforcing rods 2 are arranged along a steel skeleton column 1 with a H-shaped lateral section vertically extended and steel skeleton beams 3 are fixed by welding at the sides. A steel pipe joints 4 provided with ribs 5 in the inside wall is equipped around the steel column and the steel reinforcing rods 2. Next, a plurality of steel hoops are horizontally applied over a plurality of steel rods 2 and molding frames are set at the position shown by dotted lines and then concrete is placed. The adhesion of the steel pipe 4 with the concrete is made stronger by the ribs 5 to form a jointed structure of the steel framed reinforced concrete column and the steel beam 3. In this way, the reinforcing rods 2 can be freely arranged by fixing the beam 3 at the side of steel pipe 4 and concrete is securely filled inside the steel framed reinforced concrete column to facilitate the construction.

2. Description of the Related Art In the construction of buildings and the like, a mixed structure in which steel-framed reinforced concrete columns and steel-framed beams are joined is sometimes used. The reason for this is that this reinforced concrete column has the advantage of being more earthquake-resistant than concrete columns or reinforced concrete columns because it has reinforcing bars and column steel frames that are rich in toughness. Further, since the steel frame beam is lighter than the reinforced concrete beam and does not require reinforcement bar arrangement, it has an advantage that a long span frame structure is possible and the workability thereof is good.

SUMMARY OF THE INVENTION In the above conventional technique,
At the joint between the steel-framed reinforced concrete column 30 and the steel-framed beam 35, the H-shaped steel of the steel-framed beam 35 becomes an obstacle, and there is a problem that the main reinforcing bars 32 of the steel-framed reinforced concrete column 30 cannot be freely arranged. In addition, since the stiffener 34 is provided at the joint portion to prevent its local deformation, the stiffener 34 impedes the flow of concrete, and it is difficult to pour concrete into the steel reinforced concrete columns 30 and sufficiently fill it. There is also the problem that Further, the H-shaped steel of the steel beam 35 and the steel reinforced concrete column 30
The cross steel frame 31 is firmly joined by welding or the like,
The concrete of the steel beam 35 and the steel reinforced concrete column 30 is joined by the bearing force and adhesive force of this concrete. Therefore, when the force is transmitted from the steel beam 35 to the steel reinforced concrete column 30, this force is not evenly transmitted to the cross steel frame 31 of the steel reinforced concrete column 30 and the concrete.

By the way, conventionally, a reinforced concrete column and a steel frame beam have been joined together. FIG. 5 is a perspective view of a joint portion between a reinforced concrete column and a steel frame beam disclosed in JP-A-2-95702. 4 as shown in FIG.

The joint between the reinforced concrete column 25 and the steel beam 28 shown in FIG. 5 may be perceived to be similar to the present invention at first glance. However, the joint shown in FIG. 5 cannot join the steel frame beam 28 to the column steel frame because the column steel frame is not provided in the reinforced concrete column 25, and therefore the joining steel pipe 27 is inevitably provided with the reinforced concrete column 25. The steel frame beams 28 are joined together. On the other hand, in the case of steel frame reinforced concrete columns, since there is a column steel frame, it is common knowledge to join the column steel frame and the steel beam, and the column steel frame and the steel beam are directly connected. A structure without joining was not considered. The present invention overcomes the idea of this point, and in a joint structure of a steel-framed reinforced concrete column and a steel beam, a joined steel pipe is provided so as not to directly join the column steel frame and the steel beam.

As described above, since the joint structure of the steel-framed reinforced concrete column and the steel frame beam of the present invention is configured such that the steel beam is fixed to the side surface of the joined steel pipe, the reinforcing bar can be freely arranged. In addition, concrete is reliably filled inside the steel-framed reinforced concrete columns. Further, since the present invention is configured such that the column steel frame and the steel beam are not directly joined, the force from the steel beam is smoothly transmitted to the concrete of the steel reinforced concrete column, the column steel frame, and the rebar through the joining steel pipe. It Therefore, according to the present invention, since the load bearing ratio of the column steel frame and the steel beam is not limited, the load bearing ratio of the column steel frame and the steel beam can be freely combined.
Further, the present invention is capable of arbitrarily selecting the cross-sectional shape of the column steel frame, omitting the mounting process of a reinforcing material such as a stiffener, and reinforcing the steel beam part near the steel-framed reinforced concrete column with ribs and concrete. Since it can be omitted, the manufacturing cost can be reduced. Further, according to the present invention, the flange of the column steel frame can be positioned in any direction, and the cross-sectional strength can be selected depending on the position in which the flange is positioned.
