Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a joint structure in which a column is a rectangular steel tube and a beam made of an H-shaped steel or the like is joined to the column.

[Problems to be Solved by Prior Art and Invention]

When bolting a joint between a steel column and a steel beam made of a rectangular steel pipe, since the rectangular steel pipe is generally thin, there is a risk of insufficient strength of the joint and deformation of the joint. Various structures have been developed for adding a reinforcing metal to the above, and are proposed in JP-A-61-225437.

The inventor, in order to improve the ease of construction and the reinforcing effect,
The present invention has been invented for the purpose of developing a structure to be attached to the reinforcing metal and the outer surface of the column.

[Means for solving the problem]

The present invention relates to an outer surface of a column and a beam end at a joint between a square steel tubular steel column and a steel frame beam made of a H-shaped steel or the like in which a square ring-shaped beam end plate metal that can be inserted through the column is connected by a mounting hardware. A column-beam joint structure in which a flat plate-shaped or L-shaped reinforcing filler is interposed between the metal plate and the column, beam end plate metal, and bolts and nuts that penetrate the reinforcing filler are tightened. Details will be described based on the illustrated embodiment.

[Example 1] In Figs. 1 and 2, a column 1 is a steel frame made of square steel pipe and the like, a beam 2 is a steel frame made of H-shaped steel and the like, and the column 1 is inserted at the end of the beam 2. It is mounted by using a T-shaped mounting metal member 4 with a square end beam metal member 3.

The beam end metal plate 3 has a size such that when it is fitted on the outer periphery of the column 1, a gap of about the wall thickness of the column 1 is generated, and the gap, that is, between the outer surface of the column 1 and the beam end metal plate 3. A plate-shaped reinforcing filler 5 serving as a reinforcing plate is interposed, and a nut is screwed and tightened with a bolt 6 penetrating the pillar 1, the beam end metal plate 3, the reinforcing tailor 5, and the T-shaped fitting 4. Further, in this embodiment, since the beam end plate metal piece 3 has a square ring shape, it also serves as the end plate metal piece of each beam 2 in three directions. The bolt 6 may be a long bolt, and the column 1 may be a combination of channels and flat steel, and may not be a completely closed cross section.

With the above configuration, a reinforcing filler is added to the outer surface of the column at the column-beam joint, the cross section of the bolt penetration is corrected, the proof stress is improved and deformation is prevented, and the reinforcing filer is attached to the outer surface of the column. The workability of the assembly is good because it is possible.
In addition, since the end plate metal parts are connected between the adjacent beams, the force transmission is sure.

[Embodiment 2] FIGS. 3 and 4 show a modified example of Embodiment 1, in which a beam connecting bracket 7 which integrally serves as a mounting member is projectingly provided from the square annular beam end metal plate 3. The beam 2 is connected to the beam connecting bracket 7 using the attachment plate 8 or the like. A reinforcing plate 9 is fixed in the direction in which the beams 2 are not connected. A reinforcing filler 5 is interposed in the gap between the beam end metal plate 3 and the column 1.

[Embodiment 3] In the embodiment shown in FIGS. 5 and 6, an L-shaped reinforcing filler 5 is used, and between the outer surface of the column 1 and the square-shaped beam end metal plate 3 at the corner portion. L-shaped reinforced filler 5
Is intervening. The structure of the connecting bracket 7, etc., which is the mounting hardware, is substantially the same as that of the above-mentioned embodiment.

[Embodiment 4] FIG. 7 shows a case where, in addition to the L-shaped reinforcing filler 5, a reinforcing plate 5 having a substantially flat plate shape and one side end thereof is slightly bent is interposed in double. is there.

〔The invention's effect〕

The present invention has the above-described structure, and when a column made of a square steel pipe and a beam made of shaped steel in which a square annular beam end plate metal object that can be inserted through the column is connected by a mounting metal object is bolted, By interposing a reinforcing filler between the beam end plate and the metal plate, the wall thickness of the column is corrected, the proof stress is improved and the deformation is prevented, and the stress transmission between the adjacent beams becomes smooth.
