ㄱ 형강을 이용한 철근콘크리트용 선조립 철골조의 접합부A Connection of pre-assembled steel frame for reinforced concrete using section steel
본 발명은 철근콘크리트 부재를 구성하는 선조립 철골조의 접합부에 대한 것으로, 더욱 상세하게는 철근콘크리트용 선조립 철골조에서 상하로 인접한 ㄱ 형강의 내측에 플레이트를 접합하여 피복두께 확보에 유리하고, ㄱ 형강에 접합되는 연장플레이트에 볼트 결합공을 형성하여 볼트 결합공의 가공비를 감소시킬 수 있는 ㄱ 형강을 이용한 철근콘크리트용 선조립 철골조의 접합부에 대한 것이다.The present invention relates to the joint portion of the pre-fabricated steel frame constituting the reinforced concrete member, and more particularly, to secure the coating thickness by bonding the plate to the inner side of the a-beam adjacent up and down in the pre-fabricated steel frame for reinforced concrete, It is about the junction of the pre-fabricated steel frame for reinforced concrete using a-beam to form a bolt coupling hole in the extension plate to be joined to reduce the processing cost of the bolt coupling hole.
종래 철근콘크리트 부재의 효율성을 유지하면서 공정을 단순화하고 현장 작업량을 줄이기 위하여 철근콘크리트 기둥을 강구조화 하는 방법이 많이 연구되고 있다. 그리고 이러한 방법의 하나로 철근콘크리트 기둥의 철근 부분을 공장에서 선조립하여 철골처럼 운반 및 시공하는 PRC(Prefabricated Reinforced Concrete Column)에 대한 기술이 출원되어 등록된바 있다(특허 제10-1050956호).In order to simplify the process and reduce the amount of work in the field while maintaining the efficiency of conventional reinforced concrete members, there are many researches on the method of steel structure of reinforced concrete columns. In addition, one of such methods has been filed and registered a technology for the Prefabricated Reinforced Concrete Column (PRC) for pre-assembled reinforcement of the reinforced concrete column in the factory to transport and construct like steel frame (Patent No. 10-1050956).
또한, 철근만으로 설계하기에는 부담되는 대응력, 대규모 기둥 부재의 일부 철근을 ㄱ 형강으로 대체하는 철근콘크리트용 선조립 철골조인 PSRC(Prefabricated Steel Reinforced Concrete Column)에 대한 기술이 특허 출원된 상태에 있다.In addition, the technology for the prefabricated Steel Reinforced Concrete Column (PSRC), which is a prefabricated steel frame for reinforced concrete to replace some of the reinforcement of large column members with a section steel, is burdened to design only with rebar.
도 1은 종래 철근콘크리트용 선조립 철골조의 접합부를 도시하는 사시도이다.1 is a perspective view showing a joint of a conventional pre-assembled steel frame for reinforced concrete.
상기 선조립 철골조는 도 1에 도시된 바와 같이, 철골철근콘크리트 기둥에서 기둥 단면 중앙에 위치한 철골기둥을 분산시켜 ㄱ 형강(10a, 10b)을 외곽으로 밀어내고, 이들 강재의 주변을 띠철근으로 묶어 높은 강성을 가진 조립기둥을 형성하는 한편, 형강 사이에 기둥 주근을 배치한 골조이다. As shown in FIG. 1, the pre-assembled steel frame disperses the steel pillars located in the center of the cross-section of the steel reinforced concrete pillars to push the a-beams (10a, 10b) outwards, and tie the periphery of these steels into the band steel bars. It is a frame in which the column heads are arranged between the section steels while forming an assembly column with high rigidity.
상기 선조립 철골조의 접합은 부재 외곽에 상하로 배치된 ㄱ 형강(10a, 10b)의 외측에서 연결플레이트(20)를 덧대 용접하거나 이들을 상호 볼트 결합하여 이루어진다. Joining of the pre-assembled steel frame is made by padding the connecting plate 20 or bolted to each other on the outside of the a-beams (10a, 10b) disposed up and down on the outside of the member.
그러나 이 경우 덧대는 연결플레이트(20) 또는 볼트 등의 부재가 ㄱ 형강(10a, 10b)의 외면보다 외측에 위치하므로 피복 두께 확보에 불리하다는 단점이 있다.However, in this case, the padding member 20 or the bolt is disadvantageous in securing the coating thickness because it is located outside the outer surface of the a-beams (10a, 10b).
한편, 볼트 결합공의 가공비는 가공되는 부재의 무게에 따라 책정됨이 일반적이다. 따라서 상기 선조립 철골조의 ㄱ 형강(10a, 10b)에 볼트 결합공을 천공할 경우, 볼트 결합공은 ㄱ 형강 단부 일부에만 가공됨에도 불구하고 가공비가 고가라는 단점이 있다. 그러므로 부재 일부에 형성되는 볼트 결합공의 가공비를 줄여, 부재 가공에 소요되는 비용을 줄일 필요가 있다.On the other hand, the processing ratio of the bolt coupling hole is generally determined according to the weight of the member to be processed. Therefore, when the bolt coupling holes are drilled in the a-beams 10a and 10b of the pre-assembled steel frame, the bolt coupling holes have a disadvantage in that the processing cost is expensive despite being processed only in a portion of the a-beams. Therefore, it is necessary to reduce the processing cost of the bolt coupling hole formed in a part of the member, thereby reducing the cost required for processing the member.
