Description

Column and beam connection structure {CONNECTING STRUCTURE FOR COLUMN AND BEAM}

The present invention relates to a structure for connecting a column and a beam, and more particularly, to a structure for connecting a column and a beam that can maximize the adhesion with concrete than before, and in particular, can easily perform connection work with various beams. it's about

Many columns and beams are required in the construction of a building. Usually columns and beams are made of metal. For example, the column may be in the form of a rectangular metal pipe with an empty interior, and the beam may be an H-shaped steel pipe.

After these columns and beams are connected to each other to form the framework of the building, the building can be constructed.

In this way, many columns and beams are used in the construction of a building, and since they must be connected, various techniques for a connecting structure for joining them are known.

In this regard, local buckling occurs at the joint between the column and the beam, and the brittle fracture of the joint occurs after the frame absorbs energy to some extent. In particular, when looking at the previous earthquake damage cases, it was confirmed that brittle fracture occurred at the junction after fracture at the junction and local buckling at the beam.

In particular, in the case of a steel structure moment-resisting frame, the column flange-beam flange is welded or performed in a factory to process as a moment joint, so a joining method other than welding needs to be considered.

On the other hand, in the case of an H-shaped steel column composed of a web and a flange, the bonding process is simple in the form of an open cross-section, and in the case of a closed-section steel pipe column, due to the morphological feature of the closed cross-section of the steel pipe, the bonding is difficult. It is difficult to process, so it is difficult to secure strength and rigidity.

Considering these points, among the joining methods currently used, there is a method of reinforcing the joint by using a reinforcing means called a diaphragm to prevent deformation of the column surface, to cope with the bending load by the beam, and to enable moment joining with the beam. It is used a lot.

The diaphragm includes a through-type diaphragm type, an internal diaphragm type, and an external diaphragm type. It is a type that puts the diaphragm inside and welds it again. Although this type has a simple appearance, it requires a high level of skill for welding, and there are many difficulties in quality control according to welding inspection. The external diaphragm type reinforces and welds a diaphragm with a slope on the outside of the steel pipe. It is easy to weld, but it requires a relatively large amount of steel, and the manufacturing and processing of the diaphragm is expensive. The appearance is also complicated.

Above all, in the method using the conventional diaphragm, a number of processes up to 16 types are required, and furthermore, welding is essential.

Therefore, the need for a connection structure capable of maintaining excellent rigidity in a simple manner has emerged, and the present applicant has applied for and registered a patent for this technology.

However, in the case of registration technology, since the internal reinforcing plate has a straight structure, the adhesion to concrete may be somewhat lowered. There is a need to develop technology for a connection structure for this purpose.

Referring to these drawings, the connection structure 100 according to the present embodiment allows to maximize the adhesion with concrete than before, and in particular, to facilitate the connection work with the various beams 163 .

The connection structure 100 according to the present embodiment that can provide such an effect is a pillar 140, that is, an intermediate pillar 140, an internal reinforcement 120, a diaphragm 130, an external reinforcement 150, a side reinforcement ( 180), and a fastening unit 170 may be included.

As will be described later, since the ribs 121 are formed in the internal reinforcement 120, the adhesion to concrete can be maximized compared to the conventional one, and out-of-plane deformation of the rectangular steel pipe can be prevented. And unlike the past, since the side reinforcement 180 is applied, it is possible to easily perform a connection operation with the various beams 163 as shown in FIG. 1 . Therefore, it is very advantageous for shortening the air.

Looking at the intermediate pillar 140 first, in the connection structure 100 according to the present embodiment, the intermediate pillar 140 is a cut shape of a rectangular steel pipe. The inner reinforcement 120 is coupled to the inner surface of the intermediate pillar 140 . For coupling, a plurality of bolt holes are formed on each of the four sides of the intermediate post 140 . Although the intermediate pillar 140 and the internal reinforcement 120 may be individually fastened, in the present embodiment, they may be fastened together with the external reinforcement 150 together with the fastening unit 170 . Therefore, the workability is very high.

The inner reinforcing material 120 is a steel material formed in a plate shape with one side bent. That is, in the present embodiment, the internal reinforcement 120 includes a rib 121 that is coupled to the inner wall of the intermediate pillar 140 but protrudes inward. The rib 121 may be bent at an angle smaller than 90°, and is preferably bent at 70°.

The inner reinforcement 120 is symmetrically coupled to one pair on one side along the inner wall circumference of the intermediate pillar 140 . In particular, in this embodiment, the internal reinforcement 120 is formed to be segmented in pairs on one side of the inner wall of the intermediate pillar 140 .

At this time, the ribs 121 are formed to protrude inward from the internal reinforcement 120, and these ribs 121 act like a hook in the concrete to maximize the adhesion to the concrete than before, and prevent out-of-plane deformation of the rectangular steel pipe. do. That is, if the inner surface of the internal reinforcement 120 is flat, it is difficult to increase the adhesion to concrete. However, when the ribs 121 are formed on the internal reinforcement 120 as in the present embodiment, the ribs 121 can serve as hooks or reinforcing bars in the concrete, thereby maximizing the adhesion with the concrete.

3 and 4 , the diaphragm 130 is a rectangular plate-shaped steel material, and a through hole 132 is formed in the center of the diaphragm 130 .

In addition, the diaphragm 130 has a through slit 134 for inserting the internal reinforcing material 120 including the rib 121 is formed. The through slits 134 are formed at each of the four edges of the diaphragm 130 so that all of the four inner reinforcing materials 120 can be inserted.

In this embodiment, the diaphragm 130 is two to be coupled to the upper and lower portions of the intermediate pillar 140, respectively. The two diaphragms 130 have the same configuration except for a different position.

In FIG. 5 , the external reinforcement 150 is coupled to the outer wall of the intermediate pillar 140 . Even without the external reinforcement 150, the connection structure 100 can achieve its original purpose. However, when the external reinforcement 150 is combined, the structural rigidity of the connection structure 100 may be further increased. A plurality of through holes into which the bolts 171 of the fastening part 170 are inserted are also formed in the external reinforcement 150 .

The external reinforcement 150 is coupled to the outer wall of the intermediate pillar 140 in the remaining area except for the area in which the edge support 181 of the side reinforcement 180 is in contact. Therefore, the external reinforcement 150 is manufactured in the form of a plate material.

On the other hand, as shown in FIG. 7 , the side reinforcement 180 is a structure coupled to the intermediate pillar 140 . The side reinforcement 180 is a connecting means applied for the convenience of construction.

That is, the side reinforcement 180 is applied to improve the beam connection method when a composite beam (TU beam, hyper beam, TSC beam, etc.) is applied. In other words, after applying the side reinforcement 180 as shown in FIG. 1 , the beam 163 may be connected to the side reinforcement 180 using the beam connecting member 185 . Therefore, workability can be improved remarkably. The connection structure with composite beams or general beams will be described again in detail through the following examples.

The side reinforcement 180 that can provide this effect may include a corner support 181 and a wing portion 182 connected to the edge support 181 .

The corner support part 181 is a part that supports the middle pillar 140 and the corner regions of the upper and lower pillars 161 and 162 connected to the upper and lower sides of the intermediate pillar 140 . Accordingly, the edge support 181 has a bent structure to partially wrap the edges of the middle pillar 140 and the upper and lower pillars 161 and 162 .

The wing portion 182 forms a place connected to the beam 163 through the beam connecting member (185). In this embodiment, the wing part 182 is provided symmetrically on both sides of the edge support part 181 . This is because the beam 163 is provided symmetrically on the four sides of the intermediate column 140 , and if the beam 163 is coupled to only one side of the intermediate column 140 , the shape of the wing portion 182 corresponds to that. can be very deformed.

The fastening part 170 is a forced connection means. That is, in this embodiment, the fastening part 170 serves to integrally fasten the intermediate pillar 140 , the internal reinforcement 120 , the diaphragm 130 , the external reinforcement 150 , and the side reinforcement 180 to the corresponding ones. do

In this embodiment, the fastening part 170 integrally connects the external reinforcement 150 , the intermediate pillar 140 and the internal reinforcement 120 , and the side reinforcement 180 , the intermediate pillar 140 and the internal reinforcement 120 . ) may be combined together.

In this way, the external reinforcement 150, the intermediate pillar 140, and the internal reinforcement 120 are fastened together and assembled through the fastening part 170 or the side reinforcement 180, the intermediate pillar 140 and the internal reinforcement 120 ) are fastened together and assembled at a time, so the hassle of individually assembling structures can be avoided, and workability can be improved.

In this embodiment, the fastening unit 170 is formed of a combination of a bolt 171 and a nut 172 . At this time, unlike the bolt 171 , the nut 172 is integrally formed on the inner surface of the internal reinforcement 120 . That is, the nut 172 and the internal reinforcement 120 form an integral body.

For reference, the bolt 171 in this embodiment refers to the fastening force even if the nut 172 is fixed, that is, even if the bolt 171 is tightened only in one way without holding the nut 172 with a tool. It is preferable that it be a bolt that can be provided.

The external reinforcement 150, the intermediate pillar 140, and the internal reinforcement 120, or the side reinforcement 180, the intermediate pillar 140, and the internal reinforcement 120 are integrally fastened using the fastening part 170, respectively. In this case, since the bolt 171 of the fastening portion 170 is fastened from the outside of the external reinforcement 150 or the side reinforcement 180 , the operation is facilitated.

However, the bolts 171 are fastened to the external reinforcement 150, the intermediate pillar 140 and the internal reinforcement 120, or the side reinforcement 180, the intermediate pillar 140, and the internal reinforcement 120, respectively. A nut is needed to fix it, and it is difficult to work with the nut from the inside of the internal reinforcement 120 . Therefore, in this embodiment, the nut 172, which is an element of the fastening part 170, is integrally formed on the inner surface of the internal reinforcement 120.

As such, when the nut 172 is integrally formed on the inner surface of the inner reinforcing material 120 , the external reinforcing material 150 or the lateral reinforcing material 180 , the bolt 171 from the outside of the outer reinforcing material 150 , the intermediate pillar 140 and the inner They can be fastened in a simple way by inserting them toward the reinforcing member 120 or the side reinforcing member 180 , the intermediate pillar 140 and the inner reinforcing member 120 , and finally being fastened to the nut 172 . Therefore, workability can be very improved.

The beam 163 is an H-beam connected to the external reinforcement 150 . In the embodiment of FIG. 1 , four beams 163 are applied along the circumference of the intermediate column 140 . However, depending on the construction site, the beam 163 may be applied in two or three. Therefore, it is not limited to a specific number.

Hereinafter, the operation of the connection structure 100 will be described.

First, the components constituting the connection structure 100, that is, the internal reinforcement 120 having the ribs 121, the diaphragm 130, the intermediate pillar 140, the external reinforcement 150, the edge support 181. And the side reinforcement 180 having a wing portion 182, etc. are manufactured in advance.

Specifically, the connection structure 100 may be manufactured by simple assembly unlike conventional welding. In other words, it can be assembled just like assembling toy blocks such as Lego.

First, the four internal reinforcements 120 are penetrated through the through slits 134 of the lower diaphragm 130 . Then, the intermediate pillar 140 is coupled to the lower diaphragm 130 to which the internal reinforcement 120 is coupled.

Next, the upper diaphragm 130 is installed by inserting the four inner reinforcing materials 120 .

After the connection structure 100 thus formed is temporarily assembled at the factory with the upper and lower pillars 161 and 162 made of prismatic steel pipe, the external reinforcement 150 is combined, and then the side reinforcement 180 is connected and delivered to the site.

Of course, alternatively, only the connection structure 100 may be delivered to the site and then temporarily assembled with the upper and lower pillars 161 and 162 at the site.

When the connecting structure 100 and the column are connected in this way, the beam 163 is then coupled. The coupling of each component may be achieved by tightening the bolt 171 , which is an element of the fastening unit 170 .

According to this embodiment, which operates in the structure as described above, since the ribs 121 are formed on the internal reinforcement 120, the adhesion to concrete can be maximized compared to the conventional one, and out-of-plane deformation of the prismatic steel pipe can be prevented.

In particular, it is possible to easily proceed with the connection work with the various beams (163).

These structures and functions are the same as those of the above-described embodiments, and thus redundant descriptions are avoided.

On the other hand, unlike the above-described embodiment, the connection structure 200 according to the present embodiment is further applied with a shim plate 291 and a splice plate 292 .

The fitting 291 is a fitting plate disposed between the intermediate pillar 140 and the edge support 181 of the side reinforcement 180 , and reinforces the intermediate pillar 140 and the edge support 181 . That is, the load applied to the corner support 181 region can be reinforced by allowing the edge support 181 of the side reinforcement 180 to contact through the fitting 291 instead of directly contacting the intermediate pillar 140. .

The joint reinforcement 292 is combined with the fitting 291 from the outside of the edge support 181, so that the side reinforcement 180, the fitting 291, the middle pillar 140, and the upper and lower pillars 161 and 161 are integrally formed. to allow it to be combined.

When a plurality of fittings 291 and joint reinforcement 292 are applied as in the present embodiment, there is an effect of reinforcing the rigidity of the corresponding portion and increasing the fastening force.
