Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure between a square steel tube column having a square cross section or a circular steel tube column having a circular cross section and a shaped steel beam of an H-section steel or the like.

[0002]

There are a through-diaphragm type, an inner-diaphragm type and an outer-diaphragm type for joining a steel pipe column and a beam, but the welding length is considerably large. By the way, the inventor has previously proposed in JP-A-4-306335 and JP-A-7-252886 a structure in which a steel column having a flat cross section and a steel beam are joined by a web bending joint using a joining plate.

[0003] This invention is a development of the invention of the above publication, in which a structure capable of joining a steel pipe column and a shaped steel beam using a joining plate has been developed, and the steel tube column is joined as a middle column, an outer column or a corner column. The structure is designed so that it can be easily implemented by appropriately changing the shape of the plate and that the transmission of stress is ensured, and the welding length can be made shorter than in the conventional example.

[0004]

The joint structure between a column and a beam according to the present invention is characterized in that, at the joint between a square steel tubular column and a shaped steel beam, a joining plate arranged to form a cross in a plan view is provided in the column. The connecting plate and the web of the beam, which are crossed in a penetrating manner and protrude from the column side surface, are connected.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIGS.
As shown in FIGS. 3A and 3B and FIG. 3, the joining plates A and B, which are arranged so as to form a cross in a plan view, at the joining portion between the square steel tube column 1 and the shaped steel beam 3 each having a rectangular cross section. The joining plate and the web of the beam 3 are penetrated in the pillar and project from the side surface of the pillar. And FIG.
(A) shows a case where it is used as a middle pillar, FIG. 1 (B) shows an outer pillar, and FIG. 1 (C) shows a case where it is used as a corner pillar. In addition, FIG.
(B) shows a case in which the joining plates are arranged in parallel in one or two directions, and eccentric beams in two directions are used for connection.

FIG. 3 is a cross-sectional view showing an example of a state in which a section steel beam 3 is connected to a square steel tube column 1.

FIGS. 4 (A), 4 (B), 5 (A), 5 (B)
FIG. 6 shows a case of a circular steel tube column 1 having a circular cross section.
It is the same as the case of the square steel tube column, and the connection plates A and B, which are arranged so as to form a cross shape when viewed in a plane, cross the connection plates A and B penetrating in the circular steel tube column 1 and the beam 3 The webs are connected.

FIGS. 7 (A) and 7 (B) show the state of the intersection of the joining plates. In the case of the middle pillar, the joining plates A and B are formed so as to form a cross in the square steel tube column 1 as viewed in a plane. Are arranged so as to intersect in a penetrating manner.

In this embodiment, a vertical through hole 2 having a width slightly larger than the thickness of the bonding plate B is formed in the center of one of the bonding plates A, and the other bonding plate B is One half can be inserted into the vertical through hole 2.

Each of the joining plates A and B has an end protruding from a side surface of the square steel tubular column 1.

FIGS. 8 (A) and 8 (B) show the case of an outer column, in which an inverted U-shaped notch is formed on the side of the joining plate A, and the other joining plate B is formed in this notch. The portions where the results have become smaller intersect in a penetrating manner.

9 (A) and 9 (B), one joining plate A
Are vertically separated from each other, and the other joining plate B is formed with a vertical notch from the top and bottom at the center,
One joining plate A is arranged in the vertical notch 4 so as to intersect in a penetrating manner.

10 (A), 10 (B) and 10 (C), the central portion of one joining plate A is enlarged, and a notch is formed in the other joining plate B. Are inserted through upper and lower vertical through holes of the joining plate A. Further, flanges are provided on the upper and lower sides of the protrusion, and the protrusion is formed to have a U-shaped cross section.

FIG. 11 shows a case in which the shapes of the shaped steel beams 3 attached to the left and right of the square steel tubular column 1 are different from each other, by shifting the formation and attachment positions of the joining plates A and B or the positions of the through holes of the joining plates. .

Then, as shown in FIG. 12 and FIG. 13, the joints A and B are welded to the penetrating portions of the steel pipe columns 1 or FIG.
As shown in FIG. 4, the reinforcing steel 4 is attached, and the column 1 and the joining plate A,
Fix B. Further, concrete mortars 5 are filled so as to bury the joining plates A and B, and the joining plates A and B are fixed and the panel zone is reinforced.

[0016]

According to the present invention, since the joint plates connecting the columns and the beams intersect in the steel tube columns, the stress transmission from the beams to the beams and from the beams to the columns can be ensured, and the present invention can be used sufficiently. In particular, when welding the column and the joining plate, the welding length is shorter than in the conventional structure, and the assembling of the joining plate and the steel pipe column is easy.
