Description

Column and beam joint core {CONNECTING CORE FOR COLUMN-BEAM JOINT}

The present invention relates to a junction core between a column and a beam, and more particularly, to a core for a junction between a column and a beam that can maximize 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. Columns and beams are usually made of metal. For example, the pillar 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 joint core 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 moment-resisting frames of steel structures, column flange-beam flanges are welded or performed in factories to process moment joining, 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 joining 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 joining 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 reinforcement 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 has a through-type diaphragm type, an inner diaphragm type, and an outer diaphragm type. The through-type diaphragm type and the inner diaphragm type cut the steel pipe column and then pass the diaphragm at the beam flange position or 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 in welding, and there are many difficulties in quality control according to welding inspection. The external diaphragm type reinforces and welds a diaphragm with an inclined shape on the outside of the steel pipe. It is easy to weld, but it takes a relatively large amount of steel and costs a lot to manufacture and process the diaphragm. 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.

Accordingly, the need for a joint core capable of maintaining excellent rigidity in a simple manner has emerged, and the present applicant has applied for and registered a technology for the joint core.

However, in the case of registered technology, considering that the internal reinforcing plate has a straight structure, the adhesion to concrete may be somewhat lowered, and technology development for the joint core is necessary to compensate for this.

Referring to these drawings, the joint core 100 according to the present embodiment includes a pillar 140 , that is, an intermediate pillar 140 , an internal reinforcement 120 , a diaphragm 130 , an external reinforcement 150 , and these once It may include a fastening unit 170 for fastening to the .

The intermediate column 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 .

The inner reinforcing material 120 is a steel material and is 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 degrees, and in this embodiment, it is 70°.

The inner reinforcing material 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 with the concrete than before, and prevent out-of-plane deformation of the rectangular steel pipe. do.

The diaphragm 130 is a quadrilateral plate-shaped steel material. 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 four inner reinforcement members 120 can be inserted.

In this embodiment, there are two diaphragms 130 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.

The external reinforcement 150 is in the form of a plate, and is coupled to the outer wall of the intermediate pillar 140 . Even without the external reinforcement 150 , the joint core 100 may achieve its original purpose, but when the external reinforcement 150 is combined, the structural rigidity of the joint core 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 50 .

A stiffener 165 is formed at an end of the beam 163 in contact with the external reinforcement 150 . The stiffener 165 may distribute the cross-sectional force from the through slit 134 of the diaphragm 13 to the external reinforcement 150 . In particular, the external reinforcement 150 is connected to the beam 163 and the stiffener 165 so that it can be joined to the intermediate column 140 .

The fastening part 170 is a means for integrally fastening the external reinforcement 150 , the intermediate pillar 140 , and the internal reinforcement 120 . That is, the outer reinforcing material 150 , the intermediate pillar 140 , and the inner reinforcing material 120 are assembled together at a time through the fastening part 170 . Accordingly, the hassle of individually assembling the structure can be avoided, and workability can be improved.

In this embodiment, the fastening part 170 is formed of a combination of the bolt 171 and the nut 172 , and 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 inner reinforcing material 120 are integrally formed to form one body.

For reference, in this embodiment, the bolt 171 provides a fastening force even if the nut 172 is fixed in advance, so even if the nut 172 is not held with a tool, only the bolt 171 is tightened in one way. It can be a bolt that can do it.

When the external reinforcement 150, the intermediate pillar 140, and the internal reinforcement 120 are integrally fastened using the fastening part 170, the bolt 171 of the fastening part 170 is the outside of the external reinforcement 150. Since it is fastened from the side, the operation is easy.

However, since the bolt 171 is fastened, a nut is required to fix the external reinforcement 150 , the intermediate pillar 140 and the internal reinforcement 120 , but it is difficult to work with the nut inside the internal reinforcement 120 . Therefore, in the present 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 internal reinforcement 120 , the bolt 171 is pulled from the outside of the external reinforcement 150 toward the external reinforcement 150 , the intermediate pillar 140 and the internal reinforcement 120 . and finally fastened to the nut 172 , so that the external reinforcement 150 , the intermediate pillar 140 and the internal reinforcement 120 can be integrally fastened with a simple method. 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, three beams 163 as shown in FIG. 6 and two beams as shown in FIG. 7 may be applied. Therefore, it is not limited to a specific number.

Hereinafter, application of the abutment core 100 will be described.

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

The joint core 100 thus formed is temporarily assembled at the factory with the upper and lower columns 161 and 162 made of rectangular steel pipe, and then the external reinforcement 150 is combined and delivered to the site.

Alternatively, the assembly of the abutment core may be performed in the manner shown in FIG. 17 .

That is, after delivering only the junction core 100 to the site, it may be temporarily assembled with the upper and lower pillars 161 and 162 at the site.

When the junction core 100 and the column are connected in this way, the beam 163 is then coupled.

The coupling of each part is made by tightening the bolt 171 , which is an element of the fastening part 170 . Of course, it is advantageous to combine the internal reinforcement 120, the intermediate pillar 140, and the external reinforcement 150 at the same time by the bolt 171, but some bolts may combine only the internal reinforcement 120 and the lower pillar 162. it might be
