DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a multi-tubular steel pipe concrete column / beam.

[0002]

2. Description of the Related Art Heretofore, there has been no structure in which a steel pipe concrete column and a steel pipe concrete beam are joined to each other, and development thereof has been demanded.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to meet the above-mentioned conventional needs, and an object of the present invention is to provide a multi-tubular steel pipe concrete column which can be connected reliably and with high strength. An object of the present invention is to provide a beam joint structure.

[0004]

SUMMARY OF THE INVENTION The joint structure of a multi-tubular steel pipe concrete column / beam of the present invention comprises a steel pipe concrete column composed of multiple inner and outer steel pipes and a steel pipe concrete beam having at least two inner steel pipe beams. The joint structure is characterized in that the inner steel pipe beams are crossed while sandwiching both sides of the inner steel pipe columns, and the inner steel pipe beams are supported by the outer steel pipe columns and the concrete filled therein.

[0005] A joint structure of a multi-tubular steel tube concrete column / beam of the present invention is a joint structure of a steel tube concrete column having at least two inner steel tube columns and a steel tube concrete beam composed of multiple inner and outer steel tubes. The inner steel beam is crossed in a state of being sandwiched by the inner steel column, and the inner steel beam is supported by the outer steel column and the concrete filled therein.

[0006] The steel pipe concrete beam can be joined in a cross shape by making the steel pipe concrete beam of another steel pipe concrete beam orthogonal to the upper side of the above-mentioned inner steel pipe beam.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1, 2 and 3, A is a steel pipe concrete column, which has a double pipe structure of an outer steel pipe column 1 and an inner steel pipe column 2, and a concrete 1 'inside the outer steel pipe column 1. And the inside of the inner steel pipe column 2 is also filled with concrete 2 ′.

A steel pipe concrete beam B in the X direction and a steel pipe concrete beam C in the Y direction are joined to the head of the steel pipe concrete column A.

In the steel pipe concrete beam B in the X direction, two inner steel pipe beams 4 are arranged in parallel inside an outer steel pipe beam 3 (see FIG. 3), and concrete 3 'is placed inside the outer steel pipe beam 3. And the inside of the two inside steel pipe beams 4 is also filled with concrete 4 '.

The steel pipe concrete beam C in the Y direction is also X
It has almost the same structure as the steel pipe concrete beam B in the direction. The inner steel pipe beam 5 of the steel pipe concrete beam C is placed so as to be orthogonal to the upper side of the inner steel pipe beam 4.

Each of the steel pipe columns 1 and 2 of the steel pipe concrete column A is made of a round steel pipe, but the present invention is not limited to this, and may be a square steel pipe or a combination of a round steel pipe and a square steel pipe. Although the steel pipe beams 3 and 4 of the steel pipe concrete beams B and C are made of square steel pipes, they may be round steel pipes or a combination of square steel pipes and round steel pipes. Further, the inner steel pipe column 2 and the inner steel pipe beam 4
May be hollow without filling with concrete, and the steel pipe concrete columns A and the steel pipe concrete beams B and C may be lightened.

FIGS. 4, 5 and 6 show another embodiment of the present invention, in which a steel tube concrete beam E in the X direction and a steel tube concrete beam F in the Y direction are joined to the head of a steel tube concrete column D. Have been.

The steel pipe concrete column D has a structure in which four inner steel pipe columns 7 are arranged inside an outer steel pipe column 6, and the inside of the outer steel pipe column 6 is filled with concrete 6 '. Concrete 7 'inside each inner steel pipe column 7
Is filled.

The steel pipe concrete beam E has a double pipe structure in which an inner steel pipe beam 9 is disposed inside an outer steel pipe beam 8 (see FIG. 6), and concrete 8 'is placed inside the outer steel pipe beam 8. At the same time, concrete 9 'is also filled inside the inner steel pipe beam 9. The steel pipe concrete beam F has substantially the same structure. The inner steel pipe beam 10 of the steel pipe concrete beam F is placed so as to be orthogonal to the upper side of the inner steel pipe beam 9.

Although each of the steel pipe columns 6 and 7 of the steel pipe concrete column D is made of a round steel pipe, the present invention is not limited to this, and may be a square steel pipe or a combination of a round steel pipe and a square steel pipe. Moreover, the inside of the inner steel pipe column 7 and the inner steel pipe beam 9 may be hollow without filling with concrete, so that the steel pipe concrete column D and the steel pipe concrete beams E and F may be lightened.

[0016]

According to the present invention, since the inner steel pipe beams are crossed while sandwiching both sides of the inner steel pipe columns, and the inner steel pipe beams are supported by the outer steel pipe columns and the concrete filled therein, the steel pipe concrete columns are accommodated. And the steel pipe concrete beam can be joined reliably and with high strength.
