Description

Composite column and joint structure of composite column and beam member {COMPOSITE COLUMN AND CONNECTING STRUCTURE OF COMPOSITE COLUMN AND BEAM}

The present invention relates to a composite column with improved workability, and a joint structure of a composite column and a beam member.

It should be noted that the content described in this section merely provides background information on the present invention and does not constitute the prior art.

The concrete filled steel pipe column prevents the reduction of the strength of the steel pipe due to buckling because the concrete filled inside the steel pipe suppresses the local buckling deformation of the steel pipe.

In addition, since the filled concrete is constrained by the steel pipe, the strength increases without the concrete falling off due to cracks appearing in the reinforced concrete column or the steel frame reinforced concrete column.

Therefore, the concrete-filled steel pipe column exhibits high bearing capacity and deformability, so that it can maintain the bearing strength up to the large deformation region after the maximum bearing strength.

Out-of-plane deformation occurs in the column flange due to the stress of the beam flange caused by the moment in the column (closed section column) and the beam joint.

Therefore, the diaphragm is absolutely necessary to reinforce the stress concentration or bending deformation of the joint and to prevent the buckling of the column.

The diaphragm constituting the column-beam joint is divided into an outer diaphragm, an inner diaphragm, and a through-type diaphragm.

The external diaphragm is installed by welding a horizontal plate on the outside of the column, so it is easy to weld, but since the diaphragm is large in size and protrudes to the outside, interference with other members may occur.

In addition, when the step difference of the girder installed on the column surface occurs, since the external diaphragm suitable for each level must be installed, the junction becomes quite complicated, and when a construction error occurs, there is a problem that on-site construction becomes difficult.

The through-type diaphragm is a method of welding through a diaphragm after cutting a column, and it is not used well because of a relatively large amount of welding.

On the other hand, the inner diaphragm is a type in which the diaphragm is installed inside the steel pipe by welding, and it is difficult to weld one side of the column due to the characteristics of the column.

As shown in FIG. 1, the other side can be welded only by using a welding method called ESW, but it is virtually impossible to apply the internal diaphragm because the machine is relatively expensive and there is no equipment in Korea.

Therefore, in construction sites, we prefer details that are manufactured in factories and that can only be installed on site.

As such, if details that can use the inner diaphragm for the column are developed, the number of applications for the closed cross-section composite column can be increased. Therefore, the development of the inner diaphragm part with improved workability is urgently needed.

1 to 7D , the joint structure according to an embodiment of the present invention may include a composite column 10 and a beam.

The joint structure includes a composite column 10 and a beam member 20 connected to the composite column 10 and having an H- or I-shaped cross-section, and a flange member 21 of the beam member 20 . ) is installed in corresponding portions of the plurality of diaphragm units 210 of the diaphragm portion 200, and at least a portion of the stiffener portion 300 corresponds to the web member 22 of the beam member 20. can be installed on

The beam member 20 may be composed of a steel member having an H-shaped or I-shaped cross-section.

The beam member 20 may be composed of a pair of flange members 21 and a web member 22 connecting the pair of flange members 21 .

At this time, from the viewpoint of stress transmission between the beam member 20 and the column part 100 , the diaphragm unit 210 of the diaphragm part 200 is disposed in a portion corresponding to the flange member 21 of the beam member 20 . It may be desirable to be

Of course, while construction errors occur in the field, the flange member 21 of the beam member 20 and the diaphragm unit 210 of the diaphragm part 200 may be installed to slightly deviate from corresponding positions.

Of course, in the beam member 20 applied to the joint structure of the present invention, additional components such as reinforcing ribs may be installed in the width direction other than the H- or I-shaped cross-section.

From the viewpoint of stress transmission between the beam member 20 and the column part 100 , at least a part of the stiffener part 300 is preferably installed in a portion corresponding to the web member 22 of the beam member 20 . can

In addition, it goes without saying that various embodiments of the composite column 10 having various embodiments described above may be applied to the joint structure of the present invention.

Therefore, the detailed configuration of the column part 100, the diaphragm part 200, the stiffener part 300, the end plate part 400 of the composite column 10 has already been described, and detailed descriptions thereof are to avoid duplication. omitted for

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and variations are possible within the scope without departing from the technical spirit of the present invention described in the claims. It will be apparent to those of ordinary skill in the art.
