DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, A duplicate description thereof will be omitted.

It is also to be understood that the terms first, second, etc. used hereinafter are merely reference numerals for distinguishing between identical or corresponding components, and the same or corresponding components are defined by terms such as first, second, no.

In addition, the term " coupled " is used not only in the case of direct physical contact between the respective constituent elements in the contact relation between the constituent elements, but also means that other constituent elements are interposed between the constituent elements, Use them as a concept to cover each contact.

The modified concrete filling column according to an embodiment of the present invention (Embodiment 1) basically comprises a rectangular plate column 100 formed with an internal space 110 in which concrete is filled, And a corner reinforcement member 300 formed at an edge of the plate column 100 to resist side pressure by the center member 200 installed in the inner space 110 and concrete filled in the inner space 110 , Fig. 3).

The plate column 100 is formed by a plate, and the plate may be any material having rigidity and elasticity, but is preferably formed of iron.

The inner space 110 is a space where concrete is filled, and thus the plate column 100 serves as a permanent mold.

Accordingly, it is not necessary to form a separate concrete filling column according to an embodiment of the present invention, and only the process of charging and filling concrete in the internal space 110 of the plate column 100 is performed, Formation can be completed. Accordingly, since the construction period can be shortened dramatically, it has high utility in a construction site requiring a very short air.

The center member 200 may include a pillar steel frame 210 formed at a plurality of edges of the inner space 110 and a connecting steel frame 220 having both ends connected to the pillar steel frame 210 (Figs. 2 and 3) .

The center member 200 may be formed of an H beam, which is configured to resist loads such as axial and moment forces acting on concrete pillar columns or when used columns are used.

The column steel frame 210 is formed along the longitudinal direction of the plate column 100, and a plurality of H beams can be connected (FIG. 3).

The connecting steel frame 220 is coupled to the two column steel frames 210 at both ends thereof and may be formed at predetermined intervals along the longitudinal direction of the plate column 100 (FIG. 3).

The connecting steel frame 220 supports a load applied to the column steel frame 210 and fixes the column steel frame 220 so as not to be separated from the forming position.

When four column steel frames 210 are formed, a first connecting steel frame 221 having both ends connected to two of the four column steel frames 210, and two remaining column connecting frames 221, And a second connecting steel frame 222 having both ends connected to the steel frame 210 may be included. In this case, it is preferable that the first connecting steel frame 221 and the second connecting steel frame 222 are alternately formed at predetermined intervals along the longitudinal direction of the plate column 100 (FIGS. 2 and 3).

When the column steel frame 210 is formed at each side of the inner space 110 formed in a square shape, it is possible to resist a higher load as compared with a conventional concrete filling column, and thus it is possible to construct a concrete filling column having a large diameter .

In addition, although not shown in the drawing, the column steel frame 210 and the connecting steel frame 220 may be formed by members having various shapes such as a columnar shape and a square shape.

It is preferable in terms of structural stability that the pillar steel frame 210 is formed symmetrically with respect to the center of the inner space 110 (FIG. 2).

The edge reinforcement member 300 is resistant to the side pressure provided to the plate column 100 by the concrete filling the internal space 110.

That is, in the modified concrete pillar according to an embodiment of the present invention (Embodiment 1), the axial and moment acting on the pillar installed are resisted by the center member 200 embedded in the concrete and concrete, And the lateral pressure acting upon the concrete in the internal space 110 is resisted by the edge reinforcement member 300 formed at the edge of the plate column 100 so that the plate column 100 acting as a permanent die So that the thickness of the plate to be formed can be reduced.

The corner members may be formed in plural (Figs. 11 and 12).

The conventional concrete filling column has a problem that the axial force and moment acting on the column and the side pressure at the time of concrete pouring are concentrated on the plate column until the concrete placed in the inner space 110 is cured and has sufficient strength.

Accordingly, although the thickness of the plate for forming the plate column 100 is inevitably increased, the modified concrete pillar according to an embodiment of the present invention can be easily manufactured even when the concrete is hardened, 200, and the side pressure due to the placement of concrete can be resisted by the edge reinforcing member 300, thereby reducing the thickness of the plate forming the plate column 100. [

Thus, the effect of improving the workability and reducing the member used in the construction of the concrete filling column is added.

Here, the distance D1 from the vertex A to the first contact point B and the distance D2 from the vertex A to the second contact point C may be different (FIG. 9).

Since the contact points B and C are interpreted as the supporting points by the edge reinforcing member 300, the distance from the vertex A to the contact points B and C is set to be constant in forming the corner reinforcement member on the large- The reinforcement between the vertex A and the contact points B and C is difficult to be smoothly performed.

Therefore, the improved concrete filling column according to an embodiment of the present invention has a distance D1 from the vertex A to the first contact B and a distance D2 from the vertex A to the second contact C, The contact points B and C at various points can be formed to maximize the effect of reinforcing the corner portions.

To achieve this effect, it is preferable that the edge reinforcing member 300 is formed at predetermined intervals along the longitudinal direction of the plate column 100 (Figs. 9 and 10).

The modified concrete filling column according to an embodiment of the present invention (Embodiment 1) is constructed by a columnar steel frame 210 and a plate column 100 connected to the plate column 100 so as to resist side pressure by concrete filled in the internal space 110 , And a spacing member 400 (Figs. 2 and 3).

That is, the spacer member 400 is additionally provided in addition to the corner reinforcement member 300 as an element for resisting the side pressure caused by the pouring of the concrete into the internal space 110.

In addition, the spacing member 400 maintains a constant gap between the column steel frame 210 and the plate column 100 so that the column steel frame 210 can not be displaced.

It is preferable that the plate column 100 is formed by joining two or more rectangular plates having corners and the engaging portions 120 of the rectangular plates are formed on the surface abutting the spacing member 400 3).

Here, the spacing member 400 may be formed as a member that is in one-sided surface contact, such as "c" or "T"
