Description
본 발명은 철근연결 이음쇠에 관한 것으로 철근은 콘크리트와 함께 모든 구조물의 주재료로서 콘크리트가 높은 압축강도를 가지고는 있으나, 반면 인장강도에는 매우 취약하기 때문 에 철근을 사용 함으로서 일체화되에 외력에 저항할 수 있도록 하는 것이다.The present invention relates to reinforcing bar fittings. Reinforcing bars are concrete as the main material of all structures together with concrete, but concrete has high compressive strength, but is very vulnerable to tensile strength. To ensure that
그런데 철근의 길이는 운송 취급 사용상 제조 공정에서 일정길이로 절단되어져 공급되며 구조물의 사용목적에 따라 연결하여 사용하는 것이 대부분이며 이 경우 겹침이음, 가스압접 (용접), 별도의 철근이음 장치를 사용하는 방법이 있다.However, the length of the rebar is cut and supplied to a certain length in the manufacturing process during transportation and handling.In most cases, the rebar is connected and used according to the purpose of the structure.In this case, the overlapping joint, gas welding (welding), and a separate reinforcing bar joint are used. There is a way.
현장시공 사례는 겹침이음에 의한 방법이 주로 쓰이고 있으며, 근접된 철근과의 간격, 피복 두께의 정도, 철근의 직경 등 구조물의 여러 가지 조건에 따라 겹이음 길이에 대한 적용은 달라지며 이에 따라 철근의 소요량이 증가하게 된다.In the case of field construction, the method of overlapping joints is mainly used, and the application of the length of overlapping joints depends on various conditions of the structure, such as the distance between adjacent bars, the degree of covering thickness, and the diameter of the bars. The requirements will increase.
가스압접에 의한 철근 이음 방법은 압접시 표면과 단면부의 가공 및 가스 사용에 따른 가스안전, 산업안전관리, 화재위험성과 작업 후 비파괴검사 등 타 작업과 비교시 작업시간이 과다하게 소요 됨으로서 경제적 비용이 증가하게 된다.Rebar joint method by gas welding is economical because it requires excessive working time compared with other works such as gas safety, industrial safety management, fire risk and non-destructive inspection after work, when machining the surface and cross-section of press welding. Will increase.
철근 이음장치 경우는 이론에 치우쳐 이음장치의 제작비용이 비경제적이고 작업상 시간의 과다로 경제적 비용이 증가하는 문제점을 안고 있다.In the case of rebar joints, the manufacturing cost of the joints is not economical and the economic cost increases due to excessive working hours.
본 발명은 목적은 철근을 기계적인 방법에 의한 연결 이음쇠로 상기 서술한 철근 콘크리트의 목적상 외력에 의한 인장 및 압축응력에 대한 저항력이 충분해야 함은 물론 연결이음쇠의 부품 제작시 경제성이 확보되어야 하며, 시공상 작업이 단순 용이하여 시공성 및 공정성이 확보 되어야 한다.The object of the present invention is to connect the reinforcing bar by mechanical method to the reinforced concrete for the purpose of the above-mentioned reinforced concrete, the resistance to external forces and tensile stress should be sufficient as well as to secure the economics when manufacturing the parts of the connecting fitting In addition, construction and processability should be secured by simple and easy operation.

본 발명을 도면 기준으로 설명한다.The present invention will be described with reference to the drawings.
제1도는 생산되고 있는 이형철근의 마디 모양이 철근 굵기 및 제조 공장에 따라 다소 다르게 생산되고 있는 것을 나타낸다.Figure 1 shows that the bar shape of the deformed rebar being produced is produced somewhat differently depending on the bar thickness and the manufacturing plant.
이에 따라 철근 연결 이음쇠의 몸체(2,2')의 내면에는 마디의 요철과 대응되는 마디 홈이 파여져 연결 시에는 철근과 밀착 되어진다.Accordingly, the inner groove of the body (2, 2 ') of the reinforcing bar connection is notched in the grooves corresponding to the unevenness of the bar is in close contact with the reinforcing bar.
제2도는 대표도로서 철근과 철근을 직선으로 연결시 연결 이음쇠의 분해 사시도로서 구성 부품으로는 상부와 하부 이음쇠(2,2')상부와 하부이음쇠의 연결볼트(3) 셋나사(4) 둥근 나사부 덮개카바(5)로 구성된다.2 is an exploded perspective view of connecting fittings when connecting reinforcing bars and reinforcing bars in a straight line. The components include connecting bolts (3) of upper and lower fittings (3) and three (4) rounded upper and lower fittings. It consists of a thread cover cover (5).
상부와 하부의 이음쇠(2,2')는 길이 방향으로 중심부가 막힌 원통형으로 이음쇠의 내부 면은 철근(1)과 동일한 마디 모양의 홈이 철근과 대응되게 파여져 있어 두개의 철근을 이음쇠 좌·우에서 밀어 넣은 후 마디 홈에 안착시킨 후 상·하부 이음쇠의 연결볼트(3)로 조임하여 체결한다.The upper and lower fittings (2, 2 ') are cylindrical in the longitudinal direction, and the inner surface of the fitting is grooved in the same node shape as that of the reinforcing bar (1) so as to correspond to the reinforcing bars. Push it in, and settle it in the groove of the node, and then tighten it with the connecting bolt (3) of the upper and lower fittings.
이 연결볼트 체결구멍은 상부 이음쇠의 볼트구멍(20)에는 나사산이 없고 하부 이음쇠의 볼트 구멍(20')에만 나사산이 있어 체결작업이 보다 더 용이하다.This connection bolt fastening hole has no thread in the bolt hole 20 of the upper fitting and only a thread in the bolt hole 20 'of the lower fitting so that the fastening operation is easier.
상·하부 이음쇠를 연결볼트(3)로 체결한 후에는 하부 이음쇠의 밑 부분에 좌우 두개의 셋나사 구멍(21)을 통하여 셋나사(4)로 철근을 재조임한다.After fastening the upper and lower fittings with the connecting bolts (3), re-tighten the rebar with the set screws (4) through the two left and right three screw holes (21) at the bottom of the lower fitting.
이 셋나사 구멍(21)은 철근 마디의 끝 부분에 만들어져 있어 재조임시 철근의 미끄럼을 재 방지하는 역할을 하며 철근의 굵기에 따라 소형 지름의 철근보다는 굵은 지름의 철근 연결시 사용한다.This three screw hole 21 is made at the end of the reinforcing bar, serves to prevent the re-slip of the rebar when re-tightening, and is used when connecting the reinforcement of the coarse diameter than the rebar of the small diameter according to the thickness of the rebar.
체결과 조임이 완료된 후에는 체결된 연결 이음쇠의 길이 방향으로 양단 외면에 둥근 나사부 덮개카바(5)로 체결하게 된다. 상·하부 연결 이음쇠(2,2')의 연결볼트(3) 체결 완료 후에는 연결 이음쇠의 양단부 외면(5')에 원주방향으로 병마개 나사 모양의 둥근 나사와 둥근 나사부 덮개 카바(5) 내면의 둥근 나사가 결합 체결되어 연결이음쇠의 상하 좌우 뒤틀림과 내부철근의 결속을 더욱 강화하게 되어 철근이 외력이 더욱 강하게 되어 소기의 목적을 달성할 수가 있다.After completion of the fastening and tightening is fastened with a round screw cover cover (5) on the outer surface of both ends in the longitudinal direction of the fastened connection fitting. After the coupling bolts (3) of the upper and lower coupling fittings (2, 2 ') have been tightened, round caps having the shape of a cap with screw caps in the circumferential direction on the outer surfaces (5') of both ends of the coupling fittings Round screw is combined to tighten up and down, left and right twist of the fitting and strengthen the binding of the internal reinforcing bar is stronger external force can achieve the desired purpose.
굵기가 서로 다른 철근을 연결하는 경우는 제5도의 직경이 다른 철근 연결 이음쇠의 분해사시도에 나타난 바와 같이 구성 및 작용은 제2도 대표도에서 서술한 내용과 동일하다.In the case of connecting reinforcing bars having different thicknesses, as shown in the exploded perspective view of the reinforcing bar fittings having different diameters in FIG. 5, the structure and operation are the same as those described in the representative diagram of FIG.
본 발명에 의한 철근 연결 이음쇠는 철근 콘크리트 구조물의 안정성 학보가 가능하며, 간단한 작업으로 시공성이 뛰어나 작업시간이 단축되고, 제작 생산비용이 저렴하여, 가치창출면에서 공사비의 절감, 공기단축으로 기업의 생산성이 향상되며, 부가적으로 설계 시공간에 불협화음 해소에도 기여할 수 있다.Reinforcing bar connection fittings according to the present invention is capable of studying the stability of reinforced concrete structures, excellent workability by simple work, shortening the working time, low production and production costs, in terms of value creation, construction cost reduction, air shortage Productivity is improved, and additionally, it can contribute to resolving dissonance in design time and space.
