Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column penetration method in a joint structure of a square steel pipe column or a square steel pipe concrete column 1 and an H-shaped steel beam 4.

[0002]

2. Description of the Related Art As shown in FIG. 1, in the column penetration method, it is conventional to provide a flat plate-shaped diaphragm from the outside in the vicinity of the joint between the rectangular steel pipe column and the H-shaped steel beam without cutting the rectangular steel pipe column. Was the method.

[0003]

According to the conventional diaphragm construction method, since the diaphragm is flat, the out-of-plane drag force is weak, a large diaphragm is required, and the diaphragm and the finishing material interfere with each other. .

The present invention has been devised to solve this drawback.

[0005]

According to a first aspect of the present invention, an end portion of an H-shaped steel beam is welded to a rectangular steel tube column, and a lateral slit is formed at one end so as to have a V shape when viewed from above. Regarding the upper and lower flanges of the H-shaped steel beam, the flanges of the H-shaped steel beam are inserted into the slits of the vertical reinforcing member and welded, and the other end of the vertical reinforcing member is welded to the corner portion of the rectangular steel pipe column. The main purpose is a joint structure of a square steel pipe column and an H-shaped steel beam, which is characterized in that it is performed.

According to a second aspect of the present invention, the end portion of the H-shaped steel beam is welded to the square steel tubular column so that the H-shaped portion is formed so as to have a V shape when viewed from above.
A vertical reinforcing member is welded to the inner flange of the H-shaped steel beam, and the other end of the vertical reinforcing member is welded to the corner portion of the rectangular steel tubular column for the upper and lower flanges of the H-shaped steel beam. The main purpose is a joint structure between a rectangular steel pipe column and an H-shaped steel beam.

2 is a plan view showing an embodiment of claim 1. As shown in FIG. FIG. 3 is a sectional view taken along line AA of FIG. The slit 3 is formed in the rectangular vertical reinforcing member 2 so as to be perpendicular to the flange of the H-shaped steel frame beam 4 and to have a “C” shape when viewed from above,
The flange of the H-shaped steel frame beam 4 is inserted and welded so as to be vertically symmetrical. The other vertical side of the vertical reinforcing member 2 is welded to the corner of the square steel pipe column 1 to join the square steel pipe column 1 and the H-shaped steel beam 4.

FIG. 4 is a diagram showing an embodiment of claim 2.
Without forming the slit 3 in the rectangular vertical reinforcing member 2,
This is an example in which the vertical reinforcing member 2 is placed inside the upper and lower flanges of the shaped steel beam 4.

FIG. 5 is a sectional view taken along line BB of FIG. FIG. 4 is a sectional view taken along line CC of FIG. In this way, by accommodating the vertical reinforcing member 2 in the inner space of the upper and lower flanges of the H-shaped steel beam 4, the interference of the floor slab reinforcement is eliminated and the construction becomes easy.

If necessary, a square steel pipe column is filled with concrete. In the case of a square steel pipe concrete column,
If the concrete does not adhere well, the load from the H-shaped steel beam 4 will not be transmitted to the concrete. Therefore, a stud may be provided at a portion of the rectangular steel tube column where the H-shaped steel beam 4 is joined to improve the adhesion of the concrete. If the concrete is firmly attached to the square steel pipe concrete pillar 1, no stud is provided.

[0011]

The effect of the present invention is that the use of the vertical reinforcing member 2 perpendicular to the flange surface of the H-shaped steel beam 4 reduces the interference between the diaphragm and the finishing material.

According to the second aspect of the invention, interference with the floor member can be avoided.

Further, as compared with the conventional outer diaphragm being a flat plate, since the vertical reinforcing member is used, the second moment of area is large and the out-of-plane drag force is large.
