Description

전단보강용 조립식 철근헤드{Prefabricated reinforced head for shear reinforcement}Prefabricated reinforced head for shear reinforcement

본 발명은 전단보강용 조립식 철근헤드에 관한 것으로, 더욱 상세하게는 이형철근의 단부에 조립식으로 결합되어 작업자가 현장에서 이형철근에 용이하게 설치할 수 있도록 개선된 전단보강용 조립식 철근헤드에 관한 것이다.The present invention relates to a prefabricated reinforcing bar head for shear reinforcement, and more particularly, to an improved prefabricated reinforcing bar head for shear reinforcement that is prefabricated to the end of the deformed reinforcing bar so that the operator can easily install it on the deformed reinforcing bar in the field.

일반적으로 철근콘크리트 구조물이란 콘크리트의 내부에 철근이 매립되어 골조를 이루면서 콘크리트의 강도를 보강하도록 구성된 구조로, 현대의 건축에서 널리 적용되고 있다.In general, a reinforced concrete structure is a structure configured to reinforce the strength of concrete while reinforcing reinforcement is embedded in the concrete to form a frame, and is widely applied in modern architecture.

내진 성능을 높이기 위해 골조를 이루도록 콘크리트에 매립되는 철근은 주철근과 주철근을 연결하는 보강철근으로 구성된다. 즉, 주철근을 설치하고 주철근을 가로지르도록 다수의 보강철근을 설치한 후, 주철근과 보강철근의 단부를 연결하는 방식으로 설치된다. In order to improve the seismic performance, reinforcing bars embedded in concrete to form a frame are composed of reinforcing bars connecting the main reinforcing bars and the main reinforcing bars. That is, after installing the main reinforcing bar and installing a plurality of reinforcing bars to cross the main reinforcing bar, it is installed in a manner that connects the ends of the main reinforcing bar and the reinforcing bar.

주철근과 보강철근의 단부를 연결하는 방법의 일례를 들면, 주철근과 보강철근의 단부를 겹쳐 놓은 상태에서 결속선을 이용하여 묶어서 연결하게 된다. 이를 위해, 보강철근의 단부를 구부려서 주철근에 걸리도록 하거나 별도의 헤드를 용접 등으로 부착하여 주철근에 걸리도록 한 상태에서 결속선으로 묶게 된다.As an example of a method of connecting the ends of the main reinforcing bar and the reinforcing bar, the ends of the main reinforcing bar and the reinforcing bar are superimposed, and the ends of the main reinforcing bar and the reinforcing bar are superimposed, and the ends of the main reinforcing bar and the reinforcing bar are superimposed, and the ends of the reinforcing bar are tied together and connected. To this end, the end of the reinforcing bar is bent so that it is caught by the main reinforcing bar, or a separate head is attached to the main reinforcing bar by welding or the like, and is tied with a binding line in the state that it is caught by the main reinforcing bar.

그러나 결속선으로 묶기 위해 보강철근의 단부를 구부리거나 별도의 헤드를 용접으로 부착하는 종래의 방식은 현장에서 작업이 불가능한 단점이 있다. 따라서 현장에서는 미리 제작된 보강철근을 사용하게 되는 데, 현장의 상황에 따라 보강철근의 길이를 줄이거나 늘려야 하는 경우, 미리 제작된 보강철근을 사용하게 되면 현장 상황에 따라 대처하지 못하는 문제점이 있다.However, the conventional method in which the end of the reinforcing bar is bent or a separate head is attached by welding to tie it with a binding line has a disadvantage that it is impossible to work in the field. Therefore, in the field, pre-fabricated reinforcing bars are used, and when the length of the reinforcing bars must be reduced or increased according to the situation at the site, there is a problem in that the use of pre-fabricated reinforcing bars does not cope with the site situation.

한편, 대한민국 등록특허 제10-0652896호에는 보강철근의 단부에 헤드가 일체로 결합된 헤드철근이 개시되어 있다.Meanwhile, Korean Patent Registration No. 10-0652896 discloses a head reinforcing bar in which a head is integrally coupled to an end of a reinforcing bar.

물론, 이와 같이 철근에 헤드가 일체로 결합된 헤드철근도 상술한 바와 같이 현장 상황에 따라 대처하지 못하는 문제점이 있다. 예들 들면, 현장 상황에 따라 갑자기 헤드철근의 길이를 줄이거나 늘려야 하는 경우, 종래의 헤드철근은 이러한 상황은 대처할 수 없는 문제점이 있다.Of course, there is a problem in that the head reinforcement in which the head is integrally coupled to the reinforcing bar cannot cope with the field situation as described above. For example, if the length of the head reinforcement must be suddenly shortened or increased according to the field situation, the conventional head reinforcement has a problem that this situation cannot be coped with.
