In particular, since the connection bracket 14 is installed at a portion where the beam 13 and the column 10 are connected to each other, the connection bracket 14 functions to reinforce the connection portion, I have.

In addition, it has a function of allowing a large number of beams to be installed on the column up and down through the vertical alignment of the beam.

However, when the column 10 is formed into an angular pipe having a square cross-section, the manufacturing process becomes complicated, resulting in a problem of increased production cost. Further, there is a problem that the workability of the joint portion is deteriorated and it is difficult to secure the performance.

In addition, since the cross-shaped connecting member 15 fastens the bolts and the nuts to penetrate the column 10, the connecting operation is exposed to the outside of the column 10 and unnecessarily interferes with the cross-shaped connecting member 15, which lowers the workability.

[Steel Structure Using A-Type Column 110 for Unit Structure]

Figure 2a shows a perspective view of a unit structure 100 using the a-pillar 110 for a unit structure according to the present invention.

The unit structure 100 includes a plurality of unit columns 110 and beams 120 as a steel structure. The unit structures 100 include a plurality of horizontally connected upper and lower ends of four columns 110 disposed at corners, And the beam 120 is formed as a box-shaped skeleton.

Also, it can be seen that two beams 120 are connected to each column 110, so that one unit structure 100 can be made of a box-shaped steel structure made up of columns and beams.

Figs. 2B and 2C show a joining structure connecting the unit structures 100 according to Fig. 2A to the upper, lower, left, and right sides.

2B, the unit structures 100 are horizontally connected (horizontally joined) to each other (horizontally joined), and the unit structures 100 joined to the left and right sides of the unit structures 100 are connected vertically Vertical joining) so as to construct a plurality of unit structures.

Referring to FIG. 2B, it can be seen that two and four columns are joined to each other when horizontally connecting the four unit structures 100.

Further, according to FIG. 2C, it can be seen that, in connecting the eight unit structures 100 horizontally and vertically, additional four and eight columns are joined to each other.

Accordingly, since a plurality of columns and a plurality of beams are connected to each other at the joining portion of the column 110 and the beam 120 and the joining portion of the beam 110 and the beam 110 of the unit structure 100 adjacent to each other, It should be stable as described below.

[A-pillars 110 and beams 120 for unit structures]

3a, there is shown a perspective view of the a-pillar 110 for a unit structure of the present invention.

In other words, it can be seen that the a-shaped column 110 for the unit structure is formed by bending the central portion of the vertical plate at right angles to form the folded end portion 112.

So that the a-shaped pillar 110 for the unit structure is formed in the vertical direction at four corners of the unit structure 100 as shown in Figs. 2B and 2C, such that the pillar openings S opened between the folded ends 112 are formed .

Therefore, it can be understood that the shape is extremely simple, so that it is possible to use the same shaped preformed product as it is, or to use the manufactured preformed product, thereby making it possible to secure convenience and economical efficiency.

The width dimension of both bent ends 112 is not particularly limited, and thus the opening width of the columnar opening S can be increased or decreased.

Accordingly, the manufacturing cost can be reduced as compared with the prismatic column having the closed end face of the square, and the columnar opening S is formed on one side, so that it is not necessary to process a separate hole for joining with another member.

Referring to FIG. 3B, it can be seen that a filling material 114 such as concrete can be filled in the column opening S of the a-shaped column 110 for the unit structure.

That is, one or more plate-shaped stiffeners 115 or diaphragms may be disposed inside the a-shaped pillar 110 for the unit structure at right angles to the longitudinal direction. For example, the stiffener 115 or the diaphragm may be provided on the central portion side except for both ends of the a-shaped pillar 110 for the unit structure. When a plurality of stiffeners 115 or diaphragms are provided, they are spaced apart from one another by a predetermined distance. The stiffener 115 is preferably made of a metallic material and has the same shape as the internal cross-section of the a-shaped pillar 110 for the unit structure. The thickness of the stiffener 115 or diaphragm need not be equal to the plate thickness of the a-pillars 110 for the unit structure, but can be adjusted according to the design. By providing the stiffener 115 and the diaphragm in this manner, various strengths are increased.

A plurality of stiffeners 115 or diaphragms may be disposed in a direction perpendicular to the inside of the a-shaped pillar 110 for the unit structure. In the whole or a part of the area defined by the stiffeners 115, a mortar or non- May be installed.

For example, the beam 120 may be manufactured by directly using a C-shaped steel product or by bending or forming a steel sheet.

The beam 120 is not limited to the one having the specified cross section, and thus is not limited to the cross section exemplified.

The connection structure of the beam 120 and the a-pillar 110 for a unit structure will be described below.

That is, as shown in FIG. 3C, when one beam 120 contacts the inner side A1 of the one bent end 112a and the end face B2 extends perpendicularly to the one bent end 112a, And is in contact with the inner side surface A2 of the other bent end 112b.

The end face B2 of the other beam 120 is disposed so as to be in contact with the front face B3 of the beam 120 installed in advance and the rear face B1 to be in contact with the inner side face A2 of the other bent end 112b Able to know.

In addition, it can be seen that the bolts and nuts are welded to each other to fix the beams 120 to the a-pillars 110 for the unit structure, in particular, the upper connecting plate 131 and the lower connecting plate 132 are used.

That is, the upper connection plate 131 is formed on the upper surfaces of the beams 120 arranged perpendicular to the inner surfaces A1 and A2 of the a-shaped pillars 110 for the unit structure and the upper surface of the a- To be fixed horizontally by welding.

The lower connection plate 132 also includes a bottom surface of the beams 120 disposed perpendicularly to the inner surfaces A1 and A2 of the a-shaped pillar 110 for the unit structure and a bottom surface of the a- To be fixed by welding horizontally to the sides.

The upper coupling plate 131 and the lower coupling plate 132 are formed with coupling holes to be described later, and are used for vertical joining of the a-pillars 110 for the unit structure. That is, the fastening holes of the upper connecting plates 131 are communicated and fastened to each other by bolts and nuts. This will be described in the following second embodiment.

The beam 120 may be vertically contacted with the a-shaped pillar 110 for the unit structure or adjoined to the pillar 110 so as to face each other.

4, it can be seen that the four pillars 110 of the unit structure 100 are formed by crisscrossed column joints of open cross-section, with their respective folded ends 112 abutting each other, They can be integrated with each other by bolts or welding.

Even if the bent ends 112 are in contact with each other, since the columnar openings S are formed respectively, it is advantageous that such integration is very easy.

At this time, it can be seen that the beams 120 integrated with the column joints in the state of being joined to each other can be integrated with the end faces of the column joints at four corners.

The beams 120 adjacent to each other at the column joints are already installed in the columns 110 and may not be integrated with each other by welding or bolts.

At this time, it can be seen that four vertical connection plates 131 provided on the four pillars 110 are faced to each other to facilitate vertical bonding as in the second embodiment.

As a result, it can be seen that the columns 110 of the unit structure 100 can be simply connected to each other in the horizontal direction.

4B, bolts and nuts are used to penetrate the fastening holes 133 formed in the cross-shaped connecting member 130 and the fastening holes 123 formed in the beams 120. In this case, As a result, when the cross-shaped connecting member 140 is used, the pillars 110 can be easily connected to each other at the column connecting portion by connecting the beams 120 to each other.

[Example 2]

Referring to FIG. 5A, the second embodiment of the present invention will be described with reference to FIG. 5A. In the vertical joining of FIG. 2C, eight columns 110 disposed at the corners of eight unit structures 100 are joined together Are shown.

Four columns 110 joined horizontally to each other are vertically connected to connect eight columns,

As a result, it can be seen that the four beams 120 horizontally joined together are also vertically connected.

It can be seen that the pillars 110 of the unit structure 100 are formed by crisscrossed column joints of open cross section with their respective bent ends 112 abutting each other and these bent ends 112 are integrated with each other by bolts and nuts .

Since the pillar openings S are respectively formed even if the bent ends 112 are in contact with each other, the integration operation is very easy.

At this time, the beams 120 adjacent to each other at the column joints are already installed in the columns 110 and may not be integrated with each other by welding or bolts.

As a result, it can be seen that the columns 110 of the unit structure 100 can be easily connected to each other also in the vertical direction.

At this time, it can be seen that the upper connecting plate 131 and the lower connecting plate 132, which are in contact with each other at the column connecting portion, are connected to each other by bolts and nuts, Able to know.

5b, bolts and nuts are used to penetrate the fastening holes 133 formed in the cross-shaped connecting member 130 and the fastening holes 123 formed in the beams 120. As shown in FIG. As a result, when the cross-shaped connecting member 140 is used, the pillars 110 can be easily connected to each other at the column connecting portion by connecting the beams 120 to each other.
