Description

철근 연결 구조Rebar connection structure

본 발명은 건설, 토목 현장에서 시공물의 골격을 형성하는 철근의 연결구조에 관한 것으로서, 보다 상세하게는 연결부의 기계적 강도를 향상시키고, 연결작업이 매우 용이하여 공기단축과 비용을 절감시킬 수 있는 철근 연결구조에 관한 것이다.The present invention relates to a connection structure of the reinforcing bars forming the skeleton of the construction in construction, civil engineering, and more specifically, to improve the mechanical strength of the connection portion, the connection work is very easy to reduce the air shortening and cost It relates to the connection structure.

예컨대, 건설 및 토목 현장에서는 철근을 이용하여 기본 골격을 세운 후에 콘크리트를 타설 양생시키는 과정으로 시공물을 건축하게 된다.For example, in the construction and civil engineering site, after constructing the basic skeleton by using reinforcing bar, the construction of the concrete is built by the process of pouring concrete.

그리고 상기 철근은 제조업체에서 소정의 길이로 절단되어 공급되기 때문에 시공물의 크기에 따라 철근을 절단하거나 상호 연결하여 요구하는 길이로 만들어 사용하게 되는데, 본 발명은 철근을 길이방향으로 연결하는 것에 관계한다.And since the reinforcing bar is cut and supplied to a predetermined length from the manufacturer, the reinforcing bar is cut or interconnected according to the size of the construction to make the required length, the present invention relates to connecting the reinforcing bars in the longitudinal direction.

즉, 철근을 길이방향으로 연결함에 있어서는 여러 가지 방법이 알려져 있는데, 그 대표적인 연결방법을 살펴보면 다음과 같다.That is, a variety of methods are known for connecting the reinforcing bars in the longitudinal direction.

먼저, 연결하고자 하는 철근을 맞대어 놓고 가스불을 이용하여 그 연결부위를 용융온도까지 가열하여 융착시키는 가스 압접법이 있는데, 이 방법은 특수장비가 필요치 않고 현장에서 위치에 관계없이 시공이 가능하다는 장점은 있으나, 1급이상의 기능사 자격 보유자가 필요하고, 용융온도까지 가열하여야 함으로써, 많은 시간이 소요되며, 연결부위가 취약해지고, 초음파, X 레이 등 비파괴검사에 의하여 연결부위를 검사가 이루어져야 한다는 문제점을 내포하고 있다.First of all, there is a gas welding method in which a steel bar is connected to each other and a gas fire is used to heat the connection part to a melting temperature for fusion. This method requires no special equipment and can be constructed regardless of location. Although there is a need for qualified technicians with a level 1 or higher, heating to the melting temperature, it takes a lot of time, the connection is vulnerable, and the connection must be inspected by non-destructive tests such as ultrasound and X-rays. It is implicated.

그리고 연결하고자 하는 철근의 연결부위에 파이프 형상의 슬리이브를 끼워 놓고 이의 슬리이브를 가압하여 철근에 압착시키는 방법이 있는데, 이 방법은 철근에 별도의 가공공정이 필요치 않고 비 숙련공도 작업이 가능하다는 장점은 있으나, 철근 마디 형상에 따라 품질이 변화하고, 좁은 공간에서 작업이 불가능하며, 작업시 특수장비가 요구된다는 문제점을 내포하고 있다.In addition, there is a method of inserting a pipe-shaped sleeve into the connection portion of the reinforcing bar to be pressed and pressing the sleeve to compress the reinforcing bar. Although there is an advantage, the quality varies according to the shape of the rebar bar, it is impossible to work in a narrow space, and has a problem that requires special equipment when working.

또한, 연결하고자 하는 철근을 겹쳐 놓고 슬리이브를 끼운 후에 철근과 슬리이브 사이에 쐐기를 박아 연결하는 방법이 있는데, 이 방법은 특수 장비가 요구되고, 연결부위의 단면적이 커지게 되므로 콘크리트 단면적이 작아진다는 문제점을 내포하고 있다.In addition, there is a method of overlapping the reinforcing bars and inserting the sleeves, and then connecting a wedge between the bars and the sleeves. This method requires special equipment and increases the cross-sectional area of the connection part so that the concrete cross-sectional area is small. There is a problem with losing.

그리고 상기 방법 이외에 연결하고자 하는 부위에 슬리이브를 끼워놓고 철근과 슬리이브 사이에 화학약품(레진)을 투입하는 화학약품에 의한 방법과, 철근 선단에 테이퍼 나사를 가공하여 원통형의 연결부재를 체결하는 방법 등 여러 가지 방법과, 철근 양 선단에 나사부를 형성하여 내경부에 암나사가 형성된 슬리이브의 체결하는 방법 등 여러 가지가 알려져 있다.And in addition to the above method by inserting a sleeve in the area to be connected to the chemicals (resin) between the reinforcement and the sleeve by the chemical method, and taper screw on the end of the rebar to fasten the cylindrical connecting member Various methods such as a method and a method of forming a screw portion at both ends of the reinforcing bar and fastening a sleeve having a female thread in the inner diameter portion are known.

그러나 이들 방법은 공통적으로 연결부위의 기계적 강도가 기준치에 못미치는 등 연결부위에 대한 신뢰성이 저하되고, 연결작업이 어려우며, 비용이 크게 상승된다는 문제점을 내포하고 있다.However, these methods have a problem in that the reliability of the connection is degraded, the connection work is difficult, and the cost is greatly increased, such that the mechanical strength of the connection is less than the standard value.

또한, 철근에 나사부를 형성하는 방법에 있어서는 나사부를 형성하는 작업이 매우 어렵고, 업셋팅(Up Setting)에 의하여 얻어진 섬유상 조직을 외주 가공 및 나사가공에 의하여 파괴시키므로 그 부위에 노치(Notch)부를 발생시켜 취약하게 한다는 문제점을 안고 있다.In addition, in the method of forming the threaded portion in the reinforcing bar, it is very difficult to form the threaded portion, and the notched portion is generated at the site because the fibrous structure obtained by the upsetting is broken by the outer circumferential processing and the threading process. It has the problem of making it vulnerable.

이에 따라 본 발명자는 상기 종래 기술에 대한 문제점을 예의 연구한 결과, 연결부의 기계적 강도를 향상시키고, 연결작업이 매우 용이하여 공기단축과 비용을 절감시킬 수 있는 철근 연결구조를 제안하게 되었다.Accordingly, the present inventors have studied the problems of the prior art as a result, it has been proposed a reinforcing bar connection structure that can improve the mechanical strength of the connection portion, the connection work is very easy to reduce the air shortening and cost.
