Description

철골기둥 접합용 철골 일체형 합성ＰＣ기둥과 이를 이용한 복합기둥 시공방법{Composite PC Column for Connecting Steel Column} Steel integrated composite PC column for steel column joining and composite column construction method using same {Composite PC Column for Connecting Steel Column}

본 발명은 철골기둥을 간편하게 접합 시공하기 위한 철골 일체형 합성PC기둥과 이를 이용하여 철근콘크리트기둥과 철골기둥을 효과적으로 복합화한 복합기둥의 시공방법에 관한 것이다.
The present invention relates to a steel integrated composite PC column for the easy construction of the steel column and the method of constructing a composite column effectively composited the reinforced concrete column and the steel column using the same.

철근콘크리트구조는 철근과 콘크리트를 일체화한 구조방식으로, 압축강도가 우수하고 경제적이나 거푸집 설치 등 현장작업이 복잡한 구조방식이 된다. 반면 철골구조는 형강재 등을 볼트, 용접 등의 접합을 통해 시공하는 구조방식으로, 조립식에 의해 현장작업이 용이하다는 장점이 있으나 고가의 철골 사용으로 공사비가 비싸다는 단점이 있다. Reinforced concrete structure is a structural method integrating reinforcing bar and concrete. It has excellent compressive strength and economical structure, but it is a complex structural method such as formwork installation. On the other hand, the steel frame structure is a structural method of constructing the joining steel, such as bolts, welding, etc., there is an advantage that the on-site work is easy by the prefabricated structure, but the construction cost is expensive due to the use of expensive steel frame.

최근에는 철근콘크리트구조와 철골구조 각각의 장점을 살리는 복합구조가 제안되고 있으며, 압축부재인 기둥은 압축강도가 우수한 철근콘크리트구조를 택하고 휨부재인 보는 휨강도가 우수한 철골조를 택하는 방법이 대표적이다. 그러나 철근콘크리트기둥과 철골보의 접합이 곤란하므로, 통상 기둥부재를 철근콘크리트구조와 철골구조의 복합기둥으로 완성하고 복합기둥의 철골구조부분에 철골보를 접합하는 것이 일반적이다. Recently, a composite structure that utilizes the advantages of each of the reinforced concrete structure and the steel structure has been proposed, and the method of selecting the reinforced concrete structure of the column as the compressive member and the steel frame having the excellent flexural strength as the bending member is the typical method. . However, since it is difficult to join the reinforced concrete column and the cheolgolbo, it is common to complete the column member with a reinforced column of the reinforced concrete structure and the steel structure and to join the cheolgolbo to the steel structure portion of the composite column.

도 1은 종래 철근콘크리트와 철골을 복합화한 복합기둥에 의한 건물구조의 일례를 도시한다. 보는 바와 같이 종래 복합기둥은 앵커볼트를 돌출 매설시키면서 기둥하부를 RC로 시공하고, 이어 앵커볼트에 수평레벨을 맞추면서 베이스플레이트를 고정 설치한 후 무수축 모르타르를 충진한 다음, 베이스플레이트 위에 철골기둥을 접합 설치하는 방식으로 시공한다. 하지만 이와 같은 시공방식은 현장작업이 많아 작업성이 떨어질 뿐만 아니라 공사기간이 길어지는 단점이 있다.
Figure 1 shows an example of a building structure by a composite column of a combination of conventional reinforced concrete and steel frame. As you can see, the conventional composite column is constructed with RC under the pillar while protruding and anchoring the anchor bolt, and then fixed the base plate while leveling the horizontal level on the anchor bolt, and then filling the non-shrink mortar, and then Construct by joining and installing. However, this construction method has a lot of on-site work, there is a disadvantage not only workability but also long construction period.

본 발명은 종래 복합기둥 시공상의 문제를 개선하고자 개발된 것으로서, 현장 조립식으로 간단하게 시공할 수 있는 복합기둥 시공방법과, 이러한 복합기둥 시공방법에 바람직하게 사용하기 위한 철골 일체형 합성PC기둥을 제공하고자 한다.
The present invention has been developed to improve the problems in the conventional composite column construction, to provide a composite column construction method that can be easily installed in the field assembly type, and to provide a steel integral composite PC pillar for use in such a composite column construction method preferably do.

상기한 기술적 과제를 해결하기 위해 본 발명은, 상부에 철골기둥을 접합 설치하기 위한 기둥부재로서, 기둥철근과 기둥콘크리트가 일체화된 PC기둥본체;와, 상기 PC기둥본체의 상부구간 내부에 매설되어 PC기둥본체와 일체화된 매설철골;을 포함하여 구성되되, 상기 매설철골로, 상기 PC기둥본체의 상부면과 일치하게 위치하는 베이스플레이트; 상기 베이스플레이트 하부면에 접합되어 PC기둥본체에 매설되는 매설철골기둥; 상기 매설철골기둥의 표면에 접합되어 상기 PC기둥본체에 매설되는 스터드;를 포함하여 구성되는 것을 특징으로 하는 철골기둥 접합용 철골 일체형 합성PC기둥을 제공한다.In order to solve the above technical problem, the present invention is a pillar member for joining and installing a steel pillar on the top, the PC pillar body is integrated with the column reinforcement and pillar concrete; and, embedded in the upper section of the PC pillar body A buried steel frame integrated with the PC pillar body; including, the buried steel frame, the base plate positioned to coincide with the upper surface of the PC pillar body; Buried steel frame pillar is bonded to the lower surface of the base plate embedded in the PC pillar body; It is bonded to the surface of the buried steel pillars studs embedded in the PC pillar body; provides a steel integrated composite PC pillar for steel pillars, characterized in that it comprises a.

또한 본 발명은 상기한 특징의 철골 일체형 합성PC기둥을 반입하여 기둥위치에 설치하는 제1단계; 철골기둥을 반입하여 철골 일체형 합성PC기둥의 베이스플레이트 위에 접합 설치하는 제2단계;를 포함하여 이루어지는 것을 특징으로 하는 복합기둥 시공방법을 제공한다.
In another aspect, the present invention is the first step of importing the steel-integrated composite PC pillar of the above-described feature to install at the pillar position; It provides a composite pillar construction method comprising a; the second step of bringing the steel frame pillar bonded to the base plate of the steel integrated composite PC pillar.

본 발명에 따르면 다음과 같은 효과를 기대할 수 있다.According to the present invention, the following effects can be expected.

첫째, 종래 기둥 하부를 RC로 시공하던 복합기둥에서 RC부분을 PC화하기 때문에 전반적으로 조립식 시공방식을 구현할 수 있으며, 이에 따라 거푸집 설치, 철근배근, 콘크리트 타설, 동절기 보양 등의 현장작업을 생략할 수 있어 복합기둥의 공사기간을 단축할 수 있을 뿐만 아니라 시공품질을 향상시킬 수 있다. First, since the RC part is made into a PC in the composite pillar, which was previously constructed in the lower part of the pillar, the overall prefabricated construction method can be realized, thereby eliminating field work such as formwork installation, reinforcement, concrete placement, and winter maintenance. This can shorten the construction period of the composite column and improve the construction quality.

둘째, 상부구간에 매설철골기둥을 매설하여 합성PC기둥으로 완성하므로 그 위에 철골기둥을 접합하여 복합기둥으로 시공하면 철골부분이 연속화되기 때문에 구조적인 안정성을 유리하게 확보할 수 있다.
Second, since the buried steel pillars are buried in the upper section and completed as a composite PC pillar, when the steel pillars are joined to each other and constructed as a composite pillar, structural stability can be advantageously secured because the steel sections are continuous.
