Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam joining structure for joining beams at the column head of a square steel pipe without projecting columns.

[0002]

2. Description of the Related Art Conventionally, when a beam is joined to a column head of a rectangular steel pipe, the column protrudes upward as shown in FIG.

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned conventional problems and to provide a beam joint structure of a square steel tube column head capable of joining a beam to a square steel tube column head without projecting a column. .

[0004]

A solution for the present application devised a state where harbor this stigma of RHS Column to achieve the above object
4 that will be fixed at each provided with bolts or welded to the four corners
L -shaped hardware, a cross-shaped top plate welded to the top surface of the square steel pipe column, and an upper flange portion of a beam tip is bolted to the top plate.
And the lower flange of the beam tip is split tee.
Another object of the present invention is to provide a beam joint structure of a column head of a square steel pipe including a beam joined to the L-shaped metal member by bolts via an end plate . The L-shaped hardware extends vertically above and below the lower flange of the beam and has a height that does not reach the top surface.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing a beam joint structure of a square steel pipe according to the present invention. FIGS. 1 and 2 show a beam joint structure according to the present invention. The beam joint structure includes four L-shaped metal members (4) fixed by bolts or welding while holding the corners of the column heads of the square steel tubular column (1). 2).

The L-shaped hardware (2) is a split tee (3
a) or supports the lower flange of the beam (5) which is bolted via the end plate (3b). On the other hand, a cross-shaped top plate (4) as shown in FIG. 3 is fixed to the top surface of the rectangular steel tube column (1) by welding.

The top plate (4) is formed in a cross shape by integral welding. The top plate (4) supports the upper flange of the beam (5) to be bolted.

As described above, since the upper flange of the beam (5) is joined to the top plate (4), the rectangular steel tube column (1) does not protrude above the beam (5). Therefore, the construction of the roof slab (not shown) is not hindered by the square steel tubular column (1). Next, when beams (5) are not provided on all four sides, a reinforcing plate (6) is bolted to a surface without beams (5) as shown in FIG.

[0009]

[Effects of the Invention] The embodiment of the beam joint structure of the square steel pipe column head according to the present invention is as described above, and the effects thereof will be listed below. (1) Since the beam joint structure of the present invention welds a cross-shaped top plate particularly to the column capital, the rectangular steel tube column does not protrude upward. (2) Since the beam joint structure of the present invention uses an L-shaped hardware, the strength of the column capital is ensured.
