Description

철근연결구{Reinforcing Bar Jointer}Reinforcing Bar Jointer}

본 발명은 콘크리트 구조물의 철근연결구에 관한 것으로서, 보다 상세하게는 2개의 고정키이(30a)와 2개의 손잡이 달린 조임너트(30c)는 이동볼트(30b)형상의나사이음으로 조립되어지며, 하부 연결체(30)속에 부착된다. 또한 2개의 고정키이(40a)와 2개의 손잡이 달린 조임너트(40c)는 이동볼트(40b)형상의 나사이음으로 조립되어지며 상부연결체(40)속에 부착된다. 이러한 하부연결체(30)와 상부연결체(40)는 암나사(30d)와 수나사(40d)의 나사이음으로 일체식의 구조로 조립되어 현장에 반입된다.The present invention relates to a reinforcing connector of a concrete structure, and more specifically, two fixing keys 30a and two handle-tightening nuts 30c are assembled with screw bolts having a moving bolt 30b shape and connected to the bottom. It is attached to the sieve (30). In addition, the two fixing keys 40a and the two handle tightening nuts 40c are assembled by screw joints in the shape of the moving bolts 40b and are attached to the upper connector 40. The lower connector 30 and the upper connector 40 are assembled into an integrated structure by screwing the female screw 30d and the male screw 40d into the site.

이렇게 일체식으로 조립되어 현장에 반입된 하부연결체(30)와 상부연결체(40)는 하부연결체(30) 구멍속 방향으로 선시공된 철근(10)을 삽입시키며, 선시공된 철근(10)끝이 하부연결체(30)의 암나사(30d) 중간부에 위치토록 하며, 하부연결체(30)에 부착된 2개의 손잡이 달린 조임너트(30c)를 회전시켜 철근마디(10a) 사이의 홈에 2개의 고정키이(30a)를 고정시킨다. 그리고 후속작업으로 연결될 철근(20)을 상부연결체(40) 구멍속방향으로 삽입시킨 후, 상부연결체(40)에 부착된 2개의 고정키이(40a)가 철근마디(20a)사이의 홈에 고정될 수 있도록 상부연결체(40)를 회전시켜 위치를 조정한 후 2개의 손잡이 달린 조임너트(40c)를 회전시켜 2개의 고정키이(40a)를 고정시키는 것으로 구조상 인장 및 압축강도가 크고, 작업성이 우수하며, 기존 기술의 제반 문제점을 해결할 수 있는 장점이 있다.The lower connector 30 and the upper connector 40 which are integrally assembled and brought into the site insert the reinforcing bar 10 pre-installed in the direction of the lower connector 30 and the pre-installed rebar 10. The end is positioned in the middle of the female screw 30d of the lower connector 30, and rotates the two handled tightening nuts 30c attached to the lower connector 30 in the groove between the reinforcing bar 10a. Fix two fixing keys 30a. Then, after inserting the reinforcing bar 20 to be connected in a subsequent operation into the upper connector 40 in the hole direction, the two fixing keys 40a attached to the upper connector 40 are inserted into the grooves between the rebar nodes 20a. After adjusting the position by rotating the upper connector 40 so that it can be fixed by fixing the two fixing keys (40a) by rotating the tightening nut (40c) with two handles, the tensile and compressive strength of the structure is large, work Excellent in performance, there is an advantage that can solve all the problems of the existing technology.

기존의 철근연결이음 방법에 있어 철근의 겹치기 이음방식은 철근의 길이방향으로 인장력이나 압축력이 극히 취약한 단점이 있다. 또한 철근의 각이음부에 나사산을 만들어 연결하는 방식은 나사산을 가공하는 작업이 어렵고, 나사산의 피치와 일치하도록 철근이음부 간격을 일정하게 하여야 하는 등 현장조립시 시간과 비용이 많이 소요되는 단점 등이 있다. 본 발명은 상기한 제반 문제점을 해결하기 위한 것으로 공장등에서 조립된 연결체를 현장에 반입하여 간단한 작업으로 조립이 가능하고, 연결되는 철근의 길이방향으로 철근이음부의 간격이 불규칙하여도 조립이 가능하며, 금속재료로 제작된 고정키이에 의한 견고한 고정으로 철근이음부의 인장강도와 압축강도가 크다.In the conventional reinforcing bar connection method, the overlapping joint method of the reinforcing bar is extremely weak in tension or compression force in the longitudinal direction of the rebar. In addition, the method of making and connecting the thread to the reinforcing bar of the reinforcing bar is difficult to process the thread, and the reinforcing part of the reinforcing bar should be constant to match the pitch of the thread. There is this. The present invention is to solve the above-mentioned problems and to be assembled in a simple operation by bringing the assembly assembled in the factory, etc., it is possible to assemble even if the spacing of the reinforcing bars in the longitudinal direction of the connected reinforcing bars are irregular. It is firmly fixed by fixing key made of metal material, and its tensile and compressive strength are high.

본 발명은 상기한 문제점을 해결하기 위한 것으로서 현장작업에서 반드시 발생되는 철근이음부의 절단면 위치가 불규칙하거나 철근의 길이방향으로 간격의 차이가 발생하여도 간단한 조정으로 정확하고 견고한 조립이 가능하다.The present invention is to solve the above problems, even if the position of the cut surface of the reinforcing bar portion necessarily generated in the field work is irregular or the gap in the longitudinal direction of the rebar, it is possible to precise and robust assembly by simple adjustment.

그리고 철근마디와 마디사이의 넓은 폭을 금속재질의 고정키이로 고정시키므로써 철근이음부의 인장강도와 압축강도를 크게하는 장점이 있다. 또한 현장작업시 별도의 철근조립용 공구가 필요없으므로 작업성이 우수하고 작업이 간단하다. 선시공된 철근이음부의 연결체를 활용하여 연결될 철근을 설치할 때 지지할 수 있는 구조이므로 작업이 편리하고 시간이 단축된다.In addition, by fixing the wide width between the bar and the node with a metal fixing key has the advantage of increasing the tensile strength and compressive strength of the reinforcing bar joint. In addition, since there is no need for a separate reinforcing bar assembly tool in the field work, the workability is excellent and the work is simple. It is a structure that can be supported when installing the reinforcing bars to be connected by using the connection parts of the pre-installed reinforcing bar joints, so the work is convenient and the time is shortened.

Let them stay on Tightening nut 40c with two handles to rotate the upper connector 40 in a clockwise or counterclockwise direction so that two fixing keys 40a, which can be pressed against the grooves between the rebar nodes 20a, can be fixed. Rotate It can be applied to the horizontal reinforcing joint method other than the vertical reinforcing joint method as described above. It is the same as the method for the vertical reinforcing joint but the installation position is horizontal.

이상의 구성 및 작용에 따르면 본 발명은 철근마디와 마디사이의 홈에 견고히 밀착될 수 있는 금속재질의 고정키이로 고정되므로 철근이음부의 인장강도와 압축강도가 크고, 현장작업에서 반드시 발생하는 철근이음부간의 불규칙한 간격이 발생하여도 간단한 조정으로 철근을 견고히 고정시킬 수 있으므로 현장작업성이 우수하고 균일한 강도의 품질보증이 가능하다. 또한 철근이음작업에 별도의 조립용 공구가 필요하지 않으며, 선시공된 철근위에 조립된 상부연결체 구멍속을 연결될 철근의 하부지지대 역할로 활용하므로서 작업속도가 빠르고 경제성이 높다.According to the above configuration and operation, the present invention is fixed with a metal key that can be tightly adhered to the groove between the bar and the bar, so the tensile strength and compressive strength of the reinforcing bar is large, the reinforcing bar necessarily generated in the field work Even if irregular intervals occur between the joints, the rebar can be firmly fixed by simple adjustment, so it is excellent in the field workability and quality assurance of uniform strength is possible. In addition, there is no need for a separate assembly tool for reinforcing bars, and the work speed is high and economical by utilizing the upper connector hole assembled on the pre-installed reinforcing bars as the lower support of the reinforcing bars.
