DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a steel pipe column and an H-shaped steel beam.

[0002]

2. Description of the Related Art Various types of joint structures between steel pipe columns and H-shaped steel beams have been developed. However, H
In the connection structure for joining shaped steel beams, a split tee is attached to a steel pipe column, reinforcing materials are juxtaposed and bolted from inside and outside, and an H-shaped steel beam is welded to the split tee to form a joint. Was normal.

[0003]

However, in the joint structure as shown in FIG. 7, the transmission of the force from the beam is performed from the flange of the steel pipe to the web of the steel pipe. Steel here
The flange of the pipe refers to the plane perpendicular to the beam joining the beams,
The web portion refers to the surface of the beam in the axial direction . In this case, the flange portion of the steel pipe is weak and some reinforcement is required inside and outside the steel pipe. Moreover, the bolt for tightening the split tee must be tightened from inside and outside of the steel pipe, but some means must be taken to reach inside the steel pipe.

[0004] Accordingly, the present invention provides a steel pipe column using a one-side bolt which has a split tee shape in which force is transmitted along the web of the steel pipe, does not require reinforcement, and can be tightened from the outside of the steel pipe. A connection structure for an H-shaped steel beam is provided.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] A one-side bolt is used.
H-shaped steel frame is used for T-shaped joints to be fastened to square steel tubular columns.
In a connection structure formed by welding beams, the joint metal
The flange width is made substantially the same as the width of the square steel tubular column,
Abutting the flange on the surface of the square tubular column,
To the corners of the square steel tubular column.
The gist of the connection structure is to transmit the force from the H-shaped steel beam without using the out-of-plane resistance of the flange portion of the steel pipe column, and as much as possible use bolts to join the steel pipe column and the joint hardware. The shape is close to the web of the column, and the web surface of the steel pipe column is
One-side bolts are used so that force can be transmitted and tightening bolts do not have to reach into the steel column.

[0006]

FIG. 2 shows an embodiment. 1 is a top view, FIG. 2 is a sectional view taken along line AA, and FIG. 3 is a sectional view taken along line BB.

A T-shaped cross section of a steel pipe column 1 is fastened by a tightening bolt (one-side bolt) 2 near the web 1 ′ of the steel pipe column 1 .
This is an example in which a metal joint 3 is joined and an H-shaped steel beam 4 is welded.

The shape of the metal joint 3 having a T-shaped cross section is shown in FIG.
Attaching the mold metal (cut tee) to the web part of the steel pipe
Bolt holes have been drilled in the vicinity of
5, a vertical rib is provided on the T-shaped metal as shown in FIG.
Ensure that force is transmitted through the web of the
Bolt holes are provided near the web of the steel pipe from which
There are also shapes with different shapes.

[0009]

The effect of the present invention is that the use of one-side bolts and the need for reinforcement do not require the use of a one-side bolt, so that the production and construction of the joint can be saved.
