Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-assembly column, and more particularly, to a pre-assembly column using a round angle and a rebar.
Although the existing column-related pre-assembling and new-construction methods are being used, new and innovative ones are being proposed. However, since the data are not applicable to the existing methods and are not universal, the parties who are reviewing the construction method Designers) are relying on developer data or evidence without sufficient evidence or data.
For this reason, as the construction progresses, the reviewer or the client will proceed with the construction with anxiety and suspicion. Eventually, management elements of each other increase.
Among these new methods, one of the most popular pre-assembly methods is to develop the main steel material in the pre-assembly column using the welding steel rod. In order to increase the degree of self-assemble during construction, steel material instead of reinforcing steel is inserted into the outer part of the column section Construction methods are being developed and applied.
As disclosed in the Japanese Patent No. 1233693, when a
1 is a cross-sectional view showing a conventional pre-assembly column. 1 and 1233693, a pre-assembly column using angles and angles, which are frequently used recently, has a problem in that when a
If the reinforcing bar of D16 or less is applied as stub and steel bar, the inner radius of bending of the standard hook shall be 2db or 3db (db: nominal diameter of rebar) The
An object of the present invention is to provide a pre-assembly column using a round angle and a reinforcing bar capable of satisfying the inner radius of curvature of a standard bar cage.
In order to achieve the above object, a pre-assembly column using a round angle and a reinforcing bar according to an embodiment of the present invention is an angle formed by arcuate portions bent at 90 degrees and vertically arranged at corner positions of the columns Four round angles; And a plurality of band bars surrounding the outside of the round angles and coupled to the outside of the round angles in a multi-stage manner.
Here, the inner radius of the bent portion of the band reinforcing bar may be 2 to 10 times the nominal diameter of the band reinforcing bar.
In addition, the round angle and the band bar can be joined by spot welding, respectively.
Further, the band bar may be a reinforcing bar for welding.
In addition, the round angle may be a diagonal angle so as to be applicable to a column with a semicircular section.
Further, between the round angles, a pair of auxiliary round angles having an arcuate shape bent at 90 degrees may be further included, and the auxiliary round angles may be wrapped around the auxiliary round angles in multiple stages And a plurality of auxiliary strip reinforcing bars.
In addition, the inner band radius of the bent band portion may be two to ten times the nominal diameter of the band reinforcing bar.
Further, the auxiliary round angle and the auxiliary strip reinforcement may be joined by spot welding, respectively.
Further, the auxiliary strip reinforcement may be a reinforcing steel for welding.
According to the pre-assembled column using the round angle and the reinforcing bar according to the embodiment of the present invention,
First, in order to secure universality and workability that are difficult to meet with conventional a-shaped steel, a round angle, which is a deformed steel rather than a conventional steel sheet, can be applied to satisfy the bending inner radius of the standard steel bar.
Second, to eliminate irregularities caused by the use of existing steels in applying steel of structures by using round angles and welding reinforcing bars to exclude the use of existing a-beams, Parties that apply the evidence more effectively and review the design of the structure can review the structure on a universal basis.
Third, when a curved round angle is used to secure the inner radius of the bent portion of the reinforcing bar, there is no edge, and the steel material adheres closely to the round surface, so that it is easy to secure the proof force. Moreover, The welding amount can be greatly reduced.
Fourth, it is possible to secure the effect of increasing the flexural strength by increasing the center of the round angle compared to the conventional a-shape steel.
Fifth, when the curved surface of the round angle is largely applied, it is easy to chamfer the column that can not be achieved by the conventional a-shaped steel, and it is difficult to secure the coating thickness of the steel and concrete, which is a problem in applying the conventional angle or a- The problem can be compensated.
Sixth, it is possible to form the image of a soft image than when the corner is angled when the concrete is exposed to the outside.

Note that, in the drawings, the same components are denoted by the same reference symbols as possible. Further, the detailed description of known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some of the components in the drawings are exaggerated, omitted, or schematically illustrated.

FIG. 3 shows a case where the corner of the column CL is angled, and FIG. 4 shows a case where the corner of the column is chamfered (CF). As shown in FIG. 5 (c), a portion bent at 90 degrees can be reduced to have a smaller inner radius R, and a portion bent at 90 degrees as shown in FIG. 5 (d) It is possible to apply a large radius (R) on the inner surface. If the inner radius (R) is increased, the posterior edge of the column can be easily chamfered (CF). Therefore, when the column is exposed to the outside, it can form a smoother image than when the corner is angled.
5 (a), as described above, it is difficult to manufacture the column due to the interference S1 with the inner radius of the bend of the
According to [KBC2009], when applying stirrups and barrels, the inner radius of the bending of the standard hooks should be at least 2 db, and the bending inner radius of all bends other than the standard hooks should be at least 3db.
Conventionally, it is difficult to apply this rule. However, as shown in FIG. 5 (b), the
The
When the
For reference, the role of a standard claw with an inner radius of 2 db is the fixation of the bar reinforcement (200), and all other reinforcement inner radius, 3db, is related to the continuity aspect of the bar reinforcement (200).
When the

That is, when the internal force is concentrated on the strong axis of the section of the column CL 'as in the case of FIG. 7, it is possible to easily apply the section steel of the uniaxial angle 100' to which the minimum steel amount can be applied. Even if the unbalanced angle 100 'is used, since the bending radius of the

On the other hand, in the case of penetrating the beam B as shown in FIG. 6, among the methods of joining the
When the placement of the column main member is completed, the same connection method as that of the conventional RC beam connection method can be applied for connecting the RC beams, and the various types of beams such as the beam (B) B), it is possible to minimize the specificity of the pre-assembly column and to minimize the heterogeneity due to the application of the new method by applying the universality.
For reference, it is difficult to produce various members as shown in the case of applying the conventional steelmaking production method which is a blast furnace production method in producing and applying the
