CONSTITUTION:Joint members 3 in a shape extending along the surface of a corner part are arranged to the upper and lower surfaces and both sides of the inner corner part between the flange and the web of a H-steel beam 2. A joint plate 4 is arranged astride a portion between the long side of a square steel pipe column 1 and the side of the joint member 3. The joint plate 4 is fixed to the square steel column 1 and the joint plate 4, the joint member 3, and the H-steel beam 2 are fixed to each other by means of bolt nuts.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a joint structure between a square steel pipe column having a rectangular cross section and an H-shaped steel beam.

0002

[Problems to be Solved by the Invention] The inventor has previously developed an architectural structure in which a square steel pipe column with a rectangular cross section is used and the column is housed within a wall so that the column does not protrude into the room.

[0003] In this structure, it was decided to use H-beam steel as the beam or girder between the columns in the girder direction, but there was a demand for a structure in which the metal fittings connected to the column did not protrude from the upper and lower flange surfaces of the beam or from the upper flange surface of the beam. Ta. That is, it is preferable that there is no protrusion from the upper or lower surface of the beam from the floor or ceiling fitting. This invention has been developed to meet the above demand.

0004

[Means for Solving the Problems] This invention provides a joint member at the inner corner between the flange and the web of an H-shaped steel beam, and a joint plate that extends over the long side of the square steel pipe column and the side of the joint member. Arranged,
This is a joint structure of a square steel pipe column and an H-shaped steel beam with a rectangular cross section, in which the joint plate, the square steel pipe column, the joint plate, the joint member, and the H-shaped steel beam are fixed with bolts and nuts.

[0005]

[Example] In the example shown in Figs. 1 to 6, the square steel pipe column 1
has a rectangular cross section, and an H-shaped steel beam 2 is joined to the short side of the square steel pipe column 1 in a butt state.

At the inner corner between the flange and the web of the H-shaped steel beam 2, there is a joining member 3 having a shape that follows the surface of the corner.
Place them on the top, bottom, and both sides.

[0007] Furthermore, a cross shape as shown in FIGS. 1 to 5 or a cross shape as shown in FIG.
As shown in the figure, a rectangular joint plate 4 is arranged, and the joint plate 4 and the square steel pipe column 1 are fixed by bolts and nuts 5 made of long bolts or short bolts and nuts. Note that when using long bolts, a filling member is inserted into the square steel pipe column 1. Further, the joint plate 4, the joint member 3, and the web of the H-shaped steel beam 2 are penetrated and fixed by long bolts and nuts.

[0008] The connecting plate 4 may be provided with a connecting plate 7 of cross beams projecting from the connecting plate 4 to connect beams in a direction perpendicular to the connecting plate 4. In addition, when joining the H-shaped steel beam 2 to one side of the square steel pipe column 1, the joining plate 4 can have a half shape as shown in FIG. Further, the joint plate 4 is provided with bolt holes for attaching a column and bolt holes for attaching a beam.

In the embodiments shown in FIGS. 7 to 11, the joint plate 4 is made narrow and is used on the upper flange side of the H-shaped steel beam 2, and the web of the H-shaped steel beam 2 on the side surface of the square steel pipe column 1 and A joining metal fitting 8 and a joining metal fitting 9 are used in the lower flange portion. Further, the joining plate 4 and the joining member 3 can be fixed together in advance and then attached to the pillar/beam.

0010

[Effects of the Invention] The present invention has the above-mentioned structure, and is capable of connecting a square steel pipe column with a rectangular cross section and an H-beam steel beam to a desired joint strength without causing any protrusion on the upper or lower surfaces of the beam or the upper surface of the beam. Can be joined.
